运营商在新建和扩建基站机房时,会考虑配置节能型换热设备,替代空调或者与空调进行联动控制,以保障机房内各类设备长期稳定的工作条件。节能型换热设备的基本原理是以室外的自然环境为冷源,当室外空气温度低于室内温度一定程度时,将室外低温空气与机房内高温空气进行热交换,把机房的热量带走,达到降低机房温度的目的,从而减少空调设备的使用时间,节约电能。When building and expanding base station computer rooms, operators will consider configuring energy-saving heat exchange equipment to replace air conditioners or perform linkage control with air conditioners to ensure long-term stable working conditions for all types of equipment in the computer room. The basic principle of energy-saving heat exchange equipment is based on the outdoor natural environment as the cold source. When the outdoor air temperature is lower than the indoor temperature to a certain extent, the outdoor low-temperature air and the high-temperature air in the computer room are heat exchanged to take away the heat from the computer room. To achieve the purpose of lowering the temperature of the computer room, thereby reducing the use time of air-conditioning equipment and saving electrical energy.
常规联动控制算法是传统的温控启停方法,以环境温度作为换热设备和空调联动控制的主要依据,算法简单但难以改进。常规联动控制过程如下:实时检测室内外温度,如果室内温度超过设备运行的温度上限,则启动换热设备或空调制冷:当换热设备启动条件满足时(如室内外温差达到阈值),优先启动换热设备,否则启动空调。空调和换热设备不宜频繁切换,间隔半小时以上。The conventional linkage control algorithm is a traditional temperature control start-stop method. The ambient temperature is used as the main basis for the linkage control of heat exchange equipment and air conditioners. The algorithm is simple but difficult to improve. The conventional linkage control process is as follows: real-time detection of indoor and outdoor temperature, if the indoor temperature exceeds the upper limit of the equipment operation temperature, start the heat exchange equipment or air conditioning refrigeration: when the heat exchange equipment startup conditions are met (such as the indoor and outdoor temperature difference reaches the threshold), priority is started Heat exchange equipment, otherwise start the air conditioner. Air conditioning and heat exchange equipment should not be switched frequently, with an interval of more than half an hour.
分别设置换热设备和空调的启停条件参数,比如换热设备的启 停温度可为35/25℃,温差为8℃,即,室温超过35℃时开启换热设备,室温低于25℃时停机,室内外温差超过8℃时允许启动换热设备。但实际工程应用中,启停条件参数通常很难确定,而且,针对不同地域、不同季节性气候、不同的早晚温差,启停条件参数不是固定的,如果设置固定的启停条件参数,会造成空调的频繁启动,增加能耗。常规联动控制算法仅考虑了环境温度这个外部因素,空调的启动时间和启动次数是不可预期的,且控制精度低,想要改进非常困难。Set the start and stop condition parameters of the heat exchange equipment and the air conditioner separately. For example, the start and stop temperature of the heat exchange equipment can be 35/25°C, and the temperature difference is 8°C. When the temperature difference between indoor and outdoor exceeds 8℃, it is allowed to start the heat exchange equipment. However, in actual engineering applications, it is often difficult to determine the start-stop condition parameters. Moreover, for different regions, different seasonal climates, and different morning and evening temperature differences, the start-stop condition parameters are not fixed. If a fixed start-stop condition parameter is set, it will cause Frequent activation of air conditioners increases energy consumption. The conventional linkage control algorithm only considers the external factor of the ambient temperature. The start time and number of starts of the air conditioner are unpredictable, and the control accuracy is low, so it is very difficult to improve.
四季气候轮转、气温变化、负载变化、设备实际温度等各种因素,以及这些因素的变化组合,它们都对制冷设备运行策略产生影响,因此,制冷设备控制策略缺乏可循的规律。以换热设备启动温度为35℃、空调启动温度为40℃为例,假设某基站室温超过35℃的时候不多,平常开启换热设备足以满足热负荷的要求,无需开启空调,但在某个业务高峰和气温高峰的叠加期,室温偶尔会超过40℃。按照传统控制算法,需要开启空调,但如果能提前预知40℃以上高温时间将会很短暂、不会影响设备安全运行的话(部分基站/传输设备工作范围长期可到40℃,短时50℃),实际上不需要开启空调。这样,在保障设备安全的同时,可以避免一次空调的开启,实现了一定程度的节能。Various factors such as climate rotation in four seasons, temperature changes, load changes, equipment actual temperature, and the change combination of these factors all have an impact on the operation strategy of refrigeration equipment. Therefore, the control strategy of refrigeration equipment lacks a followable law. Taking the start-up temperature of the heat exchange equipment at 35°C and the air-conditioning start-up temperature at 40°C as an example, it is assumed that the room temperature of a certain base station does not exceed 35°C often. During the overlapping period of business peaks and temperature peaks, the room temperature occasionally exceeds 40°C. According to the traditional control algorithm, the air conditioner needs to be turned on, but if the high temperature time above 40℃ can be predicted in advance, it will be very short and will not affect the safe operation of the equipment (the working range of some base stations/transmission equipment can reach 40℃ for a long time, and 50℃ for a short time) In fact, there is no need to turn on the air conditioner. In this way, while ensuring the safety of the equipment, it is possible to avoid turning on the air conditioner once, and to achieve a certain degree of energy saving.

The method can be applied to the refrigeration control system shown in FIG. 1. As shown in FIG. 1, the refrigeration control system provided by the present disclosure includes a refrigeration equipment control device, a field supervision unit (FSU), and a refrigeration equipment. FSU is a field device, set in the computer room where the refrigeration equipment is located, and includes a collection unit and an execution unit. The collection unit is used to collect real-time data such as outdoor temperature and humidity, indoor temperature, equipment load, etc., and upload it to the refrigeration control device. The execution unit is used to control the operation of the refrigeration equipment according to the instruction of the refrigeration control device. The refrigeration equipment control device can be a cloud device, and a Unified Management Expert (UME) can be selected, which is configured with a first neural network (NN) model, a second neural network model, and a third neural network model , Historical sample database and control strategy of refrigeration equipment (for example, refrigeration control algorithm). UME can obtain the predictive control plan of the refrigeration equipment according to the data reported by the FSU and the first neural network model, the second neural network model, and the third neural network model, and issue the predictive control plan to the FSU. The refrigeration equipment can include air conditioning and heat exchange equipment, and can operate according to the issued control plan.
在初始化阶段,可以在制冷设备控制装置内预设以下第一阈值至第十阈值以及各种时长。In the initialization phase, the following first threshold to tenth threshold and various durations can be preset in the refrigeration equipment control device.
第一阈值VHT,例如可以为45℃,当室内温度超过VHT时,空调无条件启动。第二阈值VLT,例如可以为15℃,当室内温度低于VLT时,空调无条件关闭,第二阈值VLT小于第一阈值VHT。第三阈值HT AC,例如可以为40℃,当室内温度超过HT AC时,可以启动空调。第四阈值HT HEE,例如可以为35℃,当室内温度超过HT HEE时,可以启动换热设备。第五阈值,用于判断是否满足间接换热设备的第二高温预启动条件。第六阈值LT,例如可以为25℃,当室内温度低于LT时,可以关闭空调和换热设备,第六阈值LT小于第四阈值HT HEE和第三阈值HT AC。第七阈值,用于判断制冷设备停机时长。第八阈值,用于判断是否满足直接换热设备的第二高温预启动条件中的室内外温差。第九阈值,用于判断是否满足直接换热设备的第二高温预启动条件中的湿度。第十阈值,用于判断空调实际运行参数与空调最优控制参数之间的误差。空调最大开启时长MAXCOT和空调最短停机时长MINCST,通常,空调最大开启时长MAXCOT为12小时,空调最短停机时长MINCST为0.5小时。 The first threshold VHT, for example, may be 45°C. When the indoor temperature exceeds VHT, the air conditioner is started unconditionally. The second threshold VLT, for example, may be 15° C., when the indoor temperature is lower than VLT, the air conditioner is unconditionally turned off, and the second threshold VLT is less than the first threshold VHT. The third threshold HT AC may be, for example, 40°C. When the indoor temperature exceeds HT AC , the air conditioner can be started. The fourth threshold HT HEE , for example, may be 35°C. When the indoor temperature exceeds HT HEE , the heat exchange equipment can be started. The fifth threshold is used to determine whether the second high temperature pre-start condition of the indirect heat exchange equipment is met. The sixth threshold LT, for example, may be 25°C. When the indoor temperature is lower than LT, the air conditioner and heat exchange equipment may be turned off. The sixth threshold LT is less than the fourth threshold HT HEE and the third threshold HT AC . The seventh threshold is used to determine how long the refrigeration equipment is down. The eighth threshold is used to determine whether the indoor and outdoor temperature difference in the second high temperature pre-start condition of the direct heat exchange equipment is met. The ninth threshold is used to determine whether the humidity in the second high temperature pre-start condition of the direct heat exchange equipment is met. The tenth threshold is used to judge the error between the actual operating parameters of the air conditioner and the optimal control parameters of the air conditioner. The maximum air conditioner on time MAXCOT and the air conditioner's shortest off time MINCST. Generally, the air conditioner's maximum on time MAXCOT is 12 hours, and the air conditioner's shortest off time MINCST is 0.5 hours.
在初始化阶段建立第一神经网络模型、第二神经网络模型和第三神经网络模型。以下结合图2,对建立第一神经网络模型、第二神经网络模型和第三神经网络模型的流程进行详细说明。In the initialization phase, the first neural network model, the second neural network model and the third neural network model are established. The flow of establishing the first neural network model, the second neural network model, and the third neural network model will be described in detail below in conjunction with FIG. 2.
如图2所示,所述建立第一神经网络模型、第二神经网络模型和第三神经网络模型包括以下步骤S21至S23。As shown in FIG. 2, the establishment of the first neural network model, the second neural network model, and the third neural network model includes the following steps S21 to S23.
在步骤S21,获取历史样本数据。In step S21, historical sample data is acquired.
样本数据可以包括室外温度、室内温度和制冷设备负荷。Sample data can include outdoor temperature, indoor temperature, and refrigeration equipment load.
在步骤S21中,制冷设备控制装置可以从历史数据库中获取历史样本数据。历史数据库中可以存储大量的每日室外温度T Rout、室内温度T Rin、制冷设备负荷L R等历史样本数据。可以根据这些参数变化 缓急程度确定采样周期,例如,室外温度T Rout的采样周期可以为10分钟,室内温度T Rin和制冷设备负荷L R的采样周期可以为5分钟。 In step S21, the refrigeration equipment control device may obtain historical sample data from the historical database. The historical database can store a large amount of historical sample data such as daily outdoor temperature T Rout , indoor temperature T Rin , refrigeration equipment load L R and so on. Can vary the degree of urgency determine the sampling period, e.g., the outdoor temperature T Rout sampling period may be 10 minutes, the sampling period T Rin room temperature and refrigeration load L R five minutes may be based on these parameters.
样本数据可以包括模拟数据和采样数据。模拟数据是当室内温度大于第三阈值HT AC时,经过模拟制冷设备的运行得到的数据。采样数据是当室内温度小于第六阈值LT且制冷设备实际停机时长大于第七阈值时采样得到的数据。也就是说,在室内温度T Rin较高、需要制冷设备运行的情况下,可以利用假负载模拟真实制冷设备,并记录T Rout、T Rin、L R等数据。在室内温度T Rin较低并且制冷设备较长停机的情况下(比如室外温度T Rout较低的季节或夜间),可以直接使用大量已有的历史样本数据,以加快历史样本数据采集速度。 The sample data may include analog data and sampling data. The simulated data is data obtained by simulating the operation of the refrigeration equipment when the indoor temperature is greater than the third threshold HT AC. The sampled data is the data sampled when the indoor temperature is less than the sixth threshold LT and the actual shutdown duration of the refrigeration equipment is greater than the seventh threshold. That is to say, when the indoor temperature T Rin is high and the refrigeration equipment needs to be operated, the dummy load can be used to simulate the real refrigeration equipment, and data such as T Rout , T Rin , L R and so on can be recorded. When the indoor temperature T Rin is low and the refrigeration equipment is out of service for a long time (such as the season or night when the outdoor temperature T Rout is low), a large amount of existing historical sample data can be directly used to speed up the collection of historical sample data.
在步骤S22,对历史样本数据仿真模拟,计算得到制冷设备每日的最优控制参数。In step S22, the historical sample data is simulated and simulated, and the daily optimal control parameters of the refrigeration equipment are calculated.
在步骤S22中,通过计算机仿真训练,建立机房环境、发热设备和制冷设备的热分布图,对历史样本数据模拟计算,输出制冷设备当日控制最优解向量(即,制冷设备每日的最优控制参数),并将定制冷设备每日的最优控制参数保存为样本数据标签。In step S22, through computer simulation training, establish the heat distribution map of the computer room environment, heating equipment and refrigeration equipment, simulate and calculate the historical sample data, and output the optimal solution vector of the refrigeration equipment control of the day (that is, the daily optimal refrigeration equipment Control parameters), and save the daily optimal control parameters of the refrigeration equipment as sample data tags.
根据仿真结果和日常经验,空调不宜频繁开启,例如,可以限定每日空调最多开启12次,每日换热设备最多开启12次。也就是说,对于空调来说,若一个开启时刻/开启时长(T moment/T hours)标签组有2个有效值,则意味着当日空调最优控制参数是:当日开启空调运行两次,每次在开启时刻T moment开启,运行时长为对应的开启时长T hours的值。 According to simulation results and daily experience, the air conditioner should not be turned on frequently. For example, the air conditioner can be turned on at most 12 times a day, and the heat exchange equipment may be turned on at most 12 times a day. In other words, for the air conditioner, if a tag group of T moment /T hours (T moment /T hours) has 2 valid values, it means that the optimal control parameter of the air conditioner for that day is: the air conditioner is turned on and run twice every day. T moment is turned on at the turn-on time, and the running time is the value of the corresponding turn-on time T hours .
在步骤S23,根据历史样本数据和制冷设备每日的最优控制参数,建立第一神经网络模型、第二神经网络模型和第三神经网络模型。In step S23, a first neural network model, a second neural network model, and a third neural network model are established based on historical sample data and daily optimal control parameters of the refrigeration equipment.
在步骤S23中,依次建立第一神经网络模型、第二神经网络模型和第三神经网络模型。In step S23, the first neural network model, the second neural network model and the third neural network model are established in sequence.
如图3所示,在对历史样本数据仿真模拟,计算得到制冷设备每日的最优控制参数的步骤(即,步骤S22)之后,并且在根据历史样本数据和制冷设备每日的最优控制参数,建立第一神经网络模型、第二神经网络模型和第三神经网络模型的步骤(即,步骤S23)之前, 本公开的制冷设备控制方法还可以包括步骤S22'至S23'。As shown in Figure 3, after the step of simulating the historical sample data to calculate the daily optimal control parameters of the refrigeration equipment (ie, step S22), and according to the historical sample data and the daily optimal control of the refrigeration equipment Parameters, before the steps of establishing the first neural network model, the second neural network model, and the third neural network model (ie, step S23), the refrigeration equipment control method of the present disclosure may further include steps S22' to S23'.
在步骤S22',对历史样本数据和制冷设备每日的最优控制参数进行归一化处理。In step S22', the historical sample data and the daily optimal control parameters of the refrigeration equipment are normalized.
可以根据以下公式,对历史样本数据和制冷设备每日的最优控制参数进行归一化处理,使数据处于范围(0,1)之间:The historical sample data and the daily optimal control parameters of the refrigeration equipment can be normalized according to the following formula, so that the data is in the range (0, 1):
Figure PCTCN2021099313-appb-000001
Figure PCTCN2021099313-appb-000001
其中,X real为实际样本的真实值,X *为归一化处理后的数据,X max为对应类型数据样本的最大值或上限值,X min为对应类型数据样本的最小值或下限值。 Among them, X real is the true value of the actual sample, X * is the normalized data, X max is the maximum or upper limit of the corresponding type of data sample, and X min is the minimum or lower limit of the corresponding type of data sample value.
对于室外温度T Rout和室内温度T Rin,X max可以为上限值100℃,X min可以为下限值-40℃,因此各真实温度X real的归一化值X *=(X real-X min)/(X max-X min)=(X real+40)/140。对于制冷设备负荷L R,设定X max可以为制冷设备的满负荷,X min可以为0,因此制冷设备负荷L R的X real归一化值X *=X real/X maxFor the outdoor temperature and the indoor temperature T Rout T Rin, X max is the upper limit may be 100 ℃, X min may be a lower limit -40 ℃, so the temperature of each of the true X real normalized value X * = (X real - X min )/(X max -X min )=(X real +40)/140. For the refrigeration equipment load L R , X max can be set as the full load of the refrigeration equipment, and X min can be 0. Therefore, the normalized value of X real of the refrigeration equipment load L R is X * = X real /X max .
对于空调开启时刻T moment-AC和换热设备开启时刻T moment-HEE(其格式可以为hh:mm:ss),可以设定X max为上限值1440(即,一天有24*60=1440分钟),X min可以为0,因此T moment-AC和T moment-HEE的归一化值X *=(hh*60+mm)/1440。对于空调开启时长T hours-AC和换热设备开启时长T hours-HEE,可以设定X max为上限值24(即,一天有24小时),X min可以为0,因此T hours-AC和T hours-HEE的归一化值X *=X real/24。 For the air conditioner on time T moment-AC and the heat exchange equipment on time T moment-HEE (the format can be hh:mm:ss), X max can be set to the upper limit of 1440 (that is, 24*60=1440 in a day Minutes), X min can be 0, so the normalized values of T moment-AC and T moment-HEE X* =(hh*60+mm)/1440. For the air conditioner on time T hours-AC and the heat exchange equipment on time T hours-HEE , X max can be set to the upper limit of 24 (that is, there are 24 hours a day), and X min can be 0, so T hours-AC and The normalized value X * of T hours-HEE = X real /24.
在步骤S23',根据归一化处理后的数据建立训练样本数据集,训练样本数据集包括训练集、验证集和测试集。In step S23', a training sample data set is established based on the normalized data. The training sample data set includes a training set, a verification set, and a test set.
在步骤S23'中,可以按照6:2:2的样本比例建立训练集、验证集和测试集。In step S23', a training set, a verification set, and a test set can be established according to a sample ratio of 6:2:2.
相应地,根据历史样本数据和制冷设备每日的最优控制参数,建立第一神经网络模型、第二神经网络模型和第三神经网络模型的步骤(即,步骤S23)可以包括:根据训练样本数据集建立第一神经网络模型、第二神经网络模型和第三神经网络模型。Correspondingly, the step of establishing the first neural network model, the second neural network model, and the third neural network model according to the historical sample data and the daily optimal control parameters of the refrigeration equipment (ie, step S23) may include: according to the training sample The data set establishes the first neural network model, the second neural network model and the third neural network model.
以下结合图4,对建立第一神经网络模型、第二神经网络模型和第三神经网络模型的流程进行详细说明。The following describes in detail the process of establishing the first neural network model, the second neural network model, and the third neural network model in conjunction with FIG. 4.
如图4所示,根据历史样本数据和制冷设备每日的最优控制参数,建立第一神经网络模型、第二神经网络模型和第三神经网络模型的步骤(即,步骤23)可以包括步骤S231至S233。As shown in Figure 4, the steps of establishing the first neural network model, the second neural network model, and the third neural network model (ie, step 23) may include steps S231 to S233.
在步骤S231,将制冷设备负荷的同期历史样本数据和预设的影响因子作为第一输入参数,并将制冷设备当日负荷的历史样本数据作为第一输出参数,建立第一神经网络模型。In step S231, the historical sample data of the load of the refrigeration equipment and the preset influence factor are used as the first input parameters, and the historical sample data of the load of the refrigeration equipment of the day is used as the first output parameter to establish a first neural network model.
影响因子可以包括以下之一或任意组合:节假日影响因子F holiday、潮汐影响因子F tide、区域事件因子F event。节假日影响因子F holiday、潮汐影响因子F tide和区域事件因子F event的取值范围均为(0,1),并且可以根据人工经验确定。例如,针对居民小区而言,正常工作日的节假日影响因子F holiday可以为0、双休日的节假日影响因子F holiday可以为0.1、春节长假的节假日影响因子F holiday可以为0.25等;针对工业园而言,工作时间段的潮汐影响因子F tide可以为0.5、加班时间段的潮汐影响因子F tide可以为0.7、深夜时间段的潮汐影响因子F tide可以为0.3等;针对某些区域而言,正常区域事件因子F event可以为0,有商业营销活动的区域事件因子F event可以为0.1,集会的区域事件因子F event可以为0.2,演唱会的区域事件因子F event可以为0.3等。 The impact factor can include one or any combination of the following: holiday impact factor F holiday , tide impact factor F tide , and regional event factor F event . The value ranges of holiday influencing factor F holiday , tide influencing factor F tide and regional event factor F event are all (0, 1), and can be determined based on manual experience. For example, for residential communities, the holiday impact factor F holiday on normal working days can be 0, the holiday impact factor F holiday on weekends can be 0.1, and the holiday impact factor F holiday on the Spring Festival holiday can be 0.25, etc.; for industrial parks , The tidal impact factor F tide during working hours can be 0.5, the tide impact factor F tide during overtime can be 0.7, and the tide impact factor F tide during the late night period can be 0.3, etc.; for some areas, normal areas The event factor F event can be 0, the regional event factor F event for commercial marketing activities can be 0.1, the regional event factor F event for gatherings can be 0.2, the regional event factor F event for concerts can be 0.3, and so on.
在步骤S232,将室外温度的同期历史样本数据和制冷设备当日负荷的历史样本数据作为第二输入参数,并将当日室内温度的历史样本数据作为第二输出参数,建立第二神经网络模型。In step S232, the historical sample data of the same period of outdoor temperature and the historical sample data of the load on the day of the refrigeration equipment are used as the second input parameter, and the historical sample data of the indoor temperature of the day is used as the second output parameter to establish a second neural network model.
在步骤S233,将当日室内温度的历史样本数据和预设的制冷效率因子作为第三输入参数,并将制冷设备当日最优控制参数的历史样本数据作为第三输出参数,建立第三神经网络模型。In step S233, the historical sample data of the indoor temperature of the day and the preset cooling efficiency factor are used as the third input parameter, and the historical sample data of the optimal control parameter of the refrigeration equipment of the day is used as the third output parameter to establish a third neural network model .
最优控制参数可以包括开启时刻T moment和开启时长T hours,即,空调开启时刻T moment-AC、换热设备开启时刻T moment-TEE,空调开启时长T hours-AC和换热设备开启时长T hours-TEEThe optimal control parameters may include the opening time T moment and the opening time T hours , that is, the air conditioner opening time T moment-AC , the heat exchange device opening time T moment-TEE , the air conditioner opening time T hours-AC and the heat exchange device opening time T hours hours-TEE .
制冷效率因子可以包括换热制冷效率因子F eff1和空调制冷效率因子F eff2。当机房环境固定时,换热制冷效率因子F eff1和空调制冷效率因子F eff2都是常量,若机房环境发生改变(比如,制冷设备更换或空间位置挪动等),则需将换热制冷效率因子F eff1和空调制冷效率因 子F eff2调整为新的常量。 The refrigeration efficiency factor may include a heat exchange refrigeration efficiency factor F eff1 and an air conditioning refrigeration efficiency factor F eff2 . When the environment of the computer room is fixed, the heat exchange and cooling efficiency factor F eff1 and the air conditioner cooling efficiency factor F eff2 are both constant. If the environment of the computer room changes (for example, the cooling equipment is replaced or the space position is moved, etc.), the heat exchange and cooling efficiency factor must be changed F eff1 and the air-conditioning refrigeration efficiency factor F eff2 are adjusted to new constants.
假设换热设备的24组T moment/T hours数据中有2个有效值,比如T moment1为0.45、T hours1为0.05和T moment2为0.60、T hours2为0.10,而空调的12组T moment/T hours都没有有效值。将开启时刻T moment回转到hh:mm:ss格式,并且将开启时长T hours回转到标准时长后,制冷设备当日最优控制参数的含义如下: Assume that there are 2 valid values in the 24 sets of T moment /T hours data of the heat exchange equipment. For example, T moment1 is 0.45, T hours1 is 0.05, T moment2 is 0.60, T hours2 is 0.10, and 12 sets of T moment /T for air conditioning None of the hours has a valid value. After turning the opening time T moment back to the hh:mm:ss format, and turning the opening time T hours back to the standard time length, the meaning of the optimal control parameters of the refrigeration equipment for that day is as follows:
(1)当日换热设备预开启运行两次;(1) The heat exchange equipment was pre-opened and operated twice on the same day;
(2)换热设备第一次开启时刻为10:48(即,0.45*24=10.8=10:48),并运行1.2小时(即,0.05*24=1.2),即,运行时间区间为10:48至12:00(即,0.45*24+0.05*24=12=12:00);(2) The first time the heat exchange equipment is turned on is 10:48 (that is, 0.45*24=10.8=10:48), and it runs for 1.2 hours (that is, 0.05*24=1.2), that is, the operating time interval is 10 : 48 to 12:00 (ie, 0.45*24+0.05*24=12=12:00);
(3)换热设备第二次开启时刻为14:24(即,0.60*24=14.4=14:24),并运行2.4小时(即,0.10*24=2.4),即,运行时间区间为14:24至16:48(即,0.60*24+0.10*24=16.8=16:48);(3) The second opening time of the heat exchange equipment is 14:24 (that is, 0.60*24=14.4=14:24), and it runs for 2.4 hours (that is, 0.10*24=2.4), that is, the operating time interval is 14 : 24 to 16:48 (ie, 0.60*24+0.10*24=16.8=16:48);
(4)当日空调不开启运行。(4) The air conditioner is not turned on on the day.
第一神经网络模型、第二神经网络模型和第三神经网络模型经过训练和优化后,可以根据实际运行环境进行部署。三个神经网络模型可以都部署在UME上,以充分利用云端的强大算力资源,从而实现实时或在线的训练。如有必要,也可以通过增加计算棒等方式,将三个神经网络模型部署在边缘侧,例如,部署在FSU上。After the first neural network model, the second neural network model, and the third neural network model are trained and optimized, they can be deployed according to the actual operating environment. The three neural network models can all be deployed on UME to make full use of the powerful computing resources of the cloud to achieve real-time or online training. If necessary, the three neural network models can also be deployed on the edge side by adding computing sticks, for example, on the FSU.
图5为本公开提供的制冷设备控制流程示意图。Fig. 5 is a schematic diagram of the control flow of the refrigeration equipment provided by the present disclosure.
如图5所示,本公开提供的制冷设备控制方法可以用于控制制冷设备运行,并且包括步骤S11至S15。As shown in FIG. 5, the refrigeration equipment control method provided by the present disclosure can be used to control the operation of the refrigeration equipment, and includes steps S11 to S15.
在步骤S11,确定当前室外温度。In step S11, the current outdoor temperature is determined.
可以根据预测温度和检测的室外温度经过加权计算得到当前室外温度T Rout,即,先确定当前时刻前预设时长内的室外温度,然后根据当前时刻前预设时长内的室外温度、当天预测温度和预设的第一权重和第二权重确定当前室外温度T Rout。通常,预设时长可以为1小时,当天预测温度可以是天气预报预测的当天温度。例如,室外温度T Rout=天气预报温度*0.8+上一小时实测室外温度*0.2。 The current outdoor temperature T Rout can be calculated by weighting according to the predicted temperature and the detected outdoor temperature, that is, the outdoor temperature within the preset time period before the current time is first determined, and then the outdoor temperature within the preset time period before the current time and the predicted temperature of the day are determined. And the preset first weight and second weight to determine the current outdoor temperature T Rout . Generally, the preset duration may be 1 hour, and the predicted temperature of the day may be the temperature predicted by the weather forecast. For example, outdoor temperature T Rout = weather forecast temperature * 0.8 + actual outdoor temperature in the last hour * 0.2.
需要说明的是,FSU可以采集室内外温度、湿度、制冷设备负荷 等数据并上传给UME。It should be noted that FSU can collect indoor and outdoor temperature, humidity, refrigeration equipment load and other data and upload it to UME.
在步骤S12,将制冷设备负荷的同期历史样本数据和预设的影响因子作为第一输入参数输入第一神经网络模型,得到制冷设备当日预测的负荷。In step S12, the historical sample data of the load of the refrigeration equipment and the preset influence factors are input as the first input parameters into the first neural network model to obtain the load predicted on the day of the refrigeration equipment.
同期是指历史上同一时期,例如,去年今天的同一时刻、前年今天的同一时刻均可以为今天该时刻的同期。The same period refers to the same period in history. For example, the same moment of today last year and the same moment of today the year before can be the same period of today.
在步骤S12中,如图6A所示,将制冷设备负荷的同期历史样本数据L N和节假日影响因子F holiday、潮汐影响因子F tide和区域事件因子F event输入第一神经网络模型,得到制冷设备当日预测的负荷L R,作为第一神经网络模型的输出值。 In step S12, as shown in FIG. 6A, input the historical sample data L N of the load of the refrigeration equipment, the holiday influencing factor F holiday , the tide influencing factor F tide and the regional event factor F event into the first neural network model to obtain the refrigeration equipment The load L R predicted on the day is used as the output value of the first neural network model.
在步骤S13,将室外温度的同期历史样本数据和制冷设备当日预测的负荷作为第二输入参数输入第二神经网络,得到当日预测的室内温度。In step S13, the historical sample data of the outdoor temperature and the load predicted on the day of the refrigeration equipment are input as the second input parameters into the second neural network to obtain the predicted indoor temperature on the day.

图7为本公开提供的空调控制流程示意图。Fig. 7 is a schematic diagram of the air-conditioning control process provided by the present disclosure.
如图7所示,本公开提供的空调控制流程包括步骤S31至S39。As shown in Figure 7, the air conditioning control process provided by the present disclosure includes steps S31 to S39.
在步骤S31,若当前室内温度大于第一阈值VHT,则执行步骤S36;否则,执行步骤S32。In step S31, if the current indoor temperature is greater than the first threshold VHT, step S36 is executed; otherwise, step S32 is executed.
在步骤S31中,若当前室内温度大于VHT,说明当前室内温度过高,则可以进一步判断空调运行是否超时(即,执行步骤S36);若当前室内温度小于或等于VHT,则可以进一步判断当前室内温度是否过低(即,执行步骤S32)。In step S31, if the current indoor temperature is greater than VHT, indicating that the current indoor temperature is too high, it can be further judged whether the air conditioner is running overtime (ie, step S36); if the current indoor temperature is less than or equal to VHT, it can be further judged Whether the temperature is too low (ie, execute step S32).
在步骤S32,若当前室内温度小于第二阈值VLT,则执行步骤S39;否则,执行步骤S33。In step S32, if the current indoor temperature is less than the second threshold VLT, step S39 is executed; otherwise, step S33 is executed.
在步骤S32中,若当前室内温度小于第二阈值VLT,说明当前室内温度过低,则空调可以因低温异常而停机(即,执行步骤S39); 若当前室内温度大于或等于第二阈值VLT,说明当前室内温度不会因高温异常而停机也不会因低温异常而停机,则可以进一步判断是否满足第一高温预启动条件(即,执行步骤S33)。In step S32, if the current indoor temperature is less than the second threshold VLT, indicating that the current indoor temperature is too low, the air conditioner can be shut down due to the abnormal low temperature (ie, step S39); if the current indoor temperature is greater than or equal to the second threshold VLT, It means that the current indoor temperature will not be shut down due to abnormal high temperature and will not shut down due to abnormal low temperature, and it can be further determined whether the first high temperature pre-start condition is met (ie, step S33 is executed).
在步骤S33,若满足第一高温预启动条件,则执行步骤S34;否则,返回步骤S31。In step S33, if the first high temperature pre-start condition is met, step S34 is executed; otherwise, step S31 is returned.
在步骤S33中,当前室内温度小于或等于第一阈值VHT且大于或等于第二阈值VLT,若满足第一高温预启动条件,则根据空调当日的最优控制参数控制空调运行(即,执行步骤S34);若不满足第一高温预启动条件,则返回步骤S31。In step S33, the current indoor temperature is less than or equal to the first threshold VHT and greater than or equal to the second threshold VLT, and if the first high temperature pre-start condition is met, the air conditioner is controlled to operate according to the optimal control parameters of the day (ie, execute step S34); if the first high temperature pre-start condition is not met, return to step S31.
第一高温预启动条件可以包括:到达空调开启时刻T moment-AC,且当前室内温度大于第三阈值HT AC,且空调实际停机时长大于空调最短停机时长MINCST。 The first high-temperature pre-start condition may include: reaching the air conditioner on time T moment-AC , the current indoor temperature is greater than the third threshold HT AC , and the actual air conditioner shutdown duration is greater than the air conditioner's shortest shutdown duration MINCST.
在步骤S34,将空调最大运行时长T on-max设置为空调开启时长T hours-AC和空调最大开启时长MAXCOT中的最小值。 In step S34, the maximum air conditioner operating time T on-max is set to the minimum value of the air conditioner on time T hours-AC and the air conditioner maximum on time MAXCOT.
在步骤S34中,可以取空调开启时长T hours-AC和空调最大开启时长MAXCOT中的最小值作为实际控制空调运行的控制参数,以保证空调运行的可靠性和安全性。 In step S34, the minimum value of the air conditioner on time T hours-AC and the air conditioner’s maximum on time MAXCOT may be taken as the control parameter for actually controlling the operation of the air conditioner, so as to ensure the reliability and safety of the air conditioner operation.
步骤S35,启动空调,并执行步骤S38。Step S35, start the air conditioner, and execute step S38.
在步骤S35中,控制空调启动后,开始记录空调实际开启时长T on-AC,将空调实际停机时长T off-AC清零,并执行步骤S38。 In step S35, after the air conditioner is controlled to start, start to record the actual on-time duration of the air conditioner T on-AC , reset the actual off-time duration of the air conditioner T off-AC to zero, and execute step S38.
在步骤S36,若空调实际停机时长T off-AC大于空调最短停机时长MINCST,则执行步骤S37;否则,返回步骤S31。 In step S36, if the air conditioner's actual shutdown time T off-AC is greater than the air conditioner's shortest shutdown time MINCST, step S37 is executed; otherwise, step S31 is returned.
在步骤S36中,当前室内温度大于第一阈值VHT,若当前空调实际停机时长T off-AC大于空调最短停机时长MINCST,说明满足高温异常启动条件,则执行空调高温异常启动操作(即,执行步骤37);若当前空调实际停机时长T off-AC小于或等于空调最短停机时长MINCST,则返回步骤S31。 In step S36, the current indoor temperature is greater than the first threshold VHT, if the current air conditioner actual shutdown duration T off-AC is greater than the air conditioner minimum shutdown duration MINCST, indicating that the high temperature abnormal start condition is met, then the air conditioner high temperature abnormal start operation is performed (ie, execute step 37); if the current actual air conditioner shutdown time T off-AC is less than or equal to the air conditioner's shortest shutdown time MINCST, return to step S31.
在步骤S37,将空调最大运行时长T on-max设置为空调最大开启时长MAXCOT,并执行步骤S35。 In step S37, the maximum air conditioner operating time Ton-max is set to the maximum air conditioner on time MAXCOT, and step S35 is executed.
在步骤S37中,在空调高温异常启动的情况下,直接根据预设 的空调最大开启时长MAXCOT控制空调的运行时长。In step S37, when the air conditioner is started abnormally at a high temperature, the operating time of the air conditioner is directly controlled according to the preset maximum on time MAXCOT of the air conditioner.
在步骤S38,若空调实际开启时长T on-AC大于或等于空调最大运行时长T on-max,则执行步骤S39;否则,保持空调当前状态。 In step S38, if the actual on-time of the air conditioner Ton-AC is greater than or equal to the maximum operating time of the air conditioner Ton-max , step S39 is executed; otherwise, the current state of the air conditioner is maintained.
空调启动之后,开始记录空调实际开启时长T on-AC,若空调实际开启时长T on-AC大于或等于空调最大运行时长T on-max,则关闭空调;否则,保持空调当前状态。 After the air conditioner is started, it starts to record the actual air conditioner on time Ton-AC . If the air conditioner’s actual on time Ton-AC is greater than or equal to the maximum air conditioner operating time Toon-max , the air conditioner is turned off; otherwise, the current state of the air conditioner is maintained.
在步骤S39,关闭空调,并返回步骤S31。In step S39, the air conditioner is turned off, and the process returns to step S31.
在步骤S39中,控制空调关闭后,开始记录空调实际停机时长T off-AC,并将空调实际开启时长T on-AC清零,随后返回步骤S31继续检测室内温度。 In step S39, after controlling the air conditioner to turn off, start recording the actual off time T off-AC of the air conditioner, and clear the actual on time T on-AC of the air conditioner to zero, and then return to step S31 to continue detecting the indoor temperature.
空调控制流程还可以包括:若当前室内温度小于第六阈值LT,则关闭空调。The air-conditioning control process may further include: if the current indoor temperature is less than the sixth threshold LT, turning off the air-conditioning.
通过上述步骤S31至S39可以看出,在应用第三神经网络模型输出的预测方案的基础上,结合预置的空调和换热设备启停策略的算法,可保障在神经网络模型预测异常时,空调和换热设备也能安全运行。在实际室温超过第一阈值VHT时,空调可以因高温异常而启动;在实际室温低于第二阈值VLT时,空调可以因低温异常而停机;在达到空调开启时刻T moment-AC且实际室温超过第三阈值HT AC且满足运行间隔超过最短停机时长MINCST时,空调将按照第三神经网络模型输出的预测方案运行,即,在空调开启时刻T moment-AC到达时启动运行,运行持续时间为空调开启时长T hours-ACFrom the above steps S31 to S39, it can be seen that based on the prediction scheme output by the third neural network model, combined with the preset air conditioning and heat exchange equipment start-stop strategy algorithm, it can ensure that when the neural network model predicts abnormalities, Air conditioning and heat exchange equipment can also operate safely. When the actual room temperature exceeds the first threshold VHT, the air conditioner can be started due to abnormal high temperature; when the actual room temperature is lower than the second threshold VLT, the air conditioner can be shut down due to the abnormal low temperature; when the air conditioner is turned on T moment-AC and the actual room temperature exceeds When the third threshold HT AC meets the requirement that the operation interval exceeds the shortest shutdown duration MINCST, the air conditioner will operate according to the prediction scheme output by the third neural network model, that is, the air conditioner will start to operate when T moment-AC arrives at the time when the air conditioner is turned on, and the operation duration is the air conditioner. Turn on time T hours-AC .
图8为本公开提供的换热设备控制流程示意图.Figure 8 is a schematic diagram of the control flow of the heat exchange equipment provided by the present disclosure.
如图8所示,本公开提供的换热设备控制流程包括步骤S41至S44。As shown in Figure 8, the heat exchange equipment control process provided by the present disclosure includes steps S41 to S44.
在步骤S41,若满足第二高温预启动条件,则执行步骤S42;否则,保持换热设备当前的状态。In step S41, if the second high temperature pre-start condition is met, step S42 is executed; otherwise, the current state of the heat exchange equipment is maintained.
需要说明的是,换热设备可以包括直接换热设备和间接换热设备,直接换热设备可以包括新风***,间接换热设备可以包括热管设备(Heat Pipe Equipment,HPE)。It should be noted that the heat exchange equipment may include direct heat exchange equipment and indirect heat exchange equipment, the direct heat exchange equipment may include a fresh air system, and the indirect heat exchange equipment may include heat pipe equipment (HPE).
当换热设备为间接换热设备时,第二高温预启动条件可以包括: 到达换热设备开启时刻T moment-TEE,且当前室内温度大于第四阈值HT HEE,且当前室内温度与室外温度的差值大于第五阈值。 When the heat exchange equipment is an indirect heat exchange equipment, the second high-temperature pre-start condition may include: reaching the turning-on time T moment-TEE of the heat exchange equipment, and the current indoor temperature is greater than the fourth threshold HT HEE , and the current indoor temperature and outdoor temperature The difference is greater than the fifth threshold.
当换热设备为直接换热设备时,第二高温预启动条件包括以下之一:When the heat exchange equipment is a direct heat exchange equipment, the second high temperature pre-start condition includes one of the following:
(1)到达换热设备开启时刻T moment-TEE,且当前室内温度大于第四阈值HT HEE,且当前室内温度与室外温度的差值大于第八阈值。第八阈值可以大于第五阈值,也就是说,在第二高温预启动条件中,直接换热设备的室内外温差要求高于间接换热设备的室内外温差要求,例如,第五阈值可以为6℃,第八阈值可与为10℃。 (1) When the heat exchange device is turned on at T moment-TEE , the current indoor temperature is greater than the fourth threshold HT HEE , and the difference between the current indoor temperature and the outdoor temperature is greater than the eighth threshold. The eighth threshold may be greater than the fifth threshold, that is, in the second high-temperature pre-start condition, the indoor and outdoor temperature difference requirements of the direct heat exchange equipment are higher than the indoor and outdoor temperature difference requirements of the indirect heat exchange equipment. For example, the fifth threshold may be 6°C, the eighth threshold can be 10°C.
(2)到达换热设备开启时刻T moment-TEE,且当前室内温度大于第四阈值HT HEE,且当前室内温度与室外温度的差值大于第八阈值,且当前室内湿度小于或等于第九阈值。也就是说,直接换热设备的第二高温预启动条件可以包括温度条件和湿度条件,例如,第九阈值可以为90%。 (2) When the heat exchange equipment is turned on at T moment-TEE , and the current indoor temperature is greater than the fourth threshold HT HEE , and the difference between the current indoor temperature and the outdoor temperature is greater than the eighth threshold, and the current indoor humidity is less than or equal to the ninth threshold . That is, the second high temperature pre-start condition of the direct heat exchange device may include temperature conditions and humidity conditions, for example, the ninth threshold may be 90%.
在步骤S42,启动换热设备。In step S42, the heat exchange equipment is started.
在步骤S42中,控制换热设备启动后,开始记录换热设备实际开启时长T on-HEE,并将换热设备实际停机时长T off-HEE清零。 In step S42, after the heat exchange equipment is controlled to start, it starts to record the actual turn-on time T on-HEE of the heat exchange equipment, and clears the actual shutdown time T off-HEE of the heat exchange equipment to zero.
在步骤S43,若换热设备实际开启时长T on-HEE大于或等于换热设备开启时长T hours-HEE,则执行步骤S44;否则,保持换热设备当前的状态。 In step S43, if the actual opening time of the heat exchange equipment Ton-HEE is greater than or equal to the opening time T hours-HEE of the heat exchange equipment, step S44 is executed; otherwise, the current state of the heat exchange equipment is maintained.
在步骤S44,关闭换热设备。In step S44, the heat exchange equipment is turned off.
在步骤S44中,控制换热设备关闭后,开始记录换热设备实际停机时长T off-HEE,并将换热设备实际开启时长T on-HEE清零。 In step S44, after controlling the heat exchange equipment to turn off, start recording the actual shutdown time T off-HEE of the heat exchange equipment, and clear the actual turn-on time T on-HEE of the heat exchange equipment to zero.
换热设备控制流程还可以包括:若当前室内温度小于第六阈值LT,则关闭换热设备。The control process of the heat exchange device may further include: if the current indoor temperature is less than the sixth threshold LT, turning off the heat exchange device.
需要说明的是,空调和间接换热设备可以同时运行,但空调和直接换热设备的运行是互斥的,即,空调和直接换热设备二者不能同时运行。另外,如果出现延误、火情告警时,需要立刻停止运行直接换热设备、关闭风阀,以保障安全。It should be noted that the air conditioner and the indirect heat exchange equipment can operate at the same time, but the operation of the air conditioner and the direct heat exchange equipment are mutually exclusive, that is, the air conditioner and the direct heat exchange equipment cannot operate at the same time. In addition, if there is a delay or a fire alarm, it is necessary to immediately stop the operation of the direct heat exchange equipment and close the air valve to ensure safety.
当换热设备为直接换热设备时,空调开启时刻与换热设备开启 时刻不同;相应地,本公开的制冷设备控制方法还可以包括:若开启空调,则关闭换热设备;若开启换热设备,则关闭空调。When the heat exchange device is a direct heat exchange device, the opening time of the air conditioner is different from the opening time of the heat exchange device; accordingly, the refrigeration device control method of the present disclosure may further include: if the air conditioner is turned on, the heat exchange device is turned off; if the heat exchange is turned on Equipment, turn off the air conditioner.
需要说明的是,空调和换热设备控制算法可以运行在UME云端,如有需要,也可以将空调和换热设备控制算法复制到FSU上,实现本地执行,在此情况下,UME要把第三神经网络预测的制冷控制方案提前下发给FSU。It should be noted that the air conditioning and heat exchange equipment control algorithm can be run on the UME cloud. If necessary, the air conditioning and heat exchange equipment control algorithm can also be copied to the FSU for local execution. In this case, the UME must first The refrigeration control plan predicted by the three neural network is issued to the FSU in advance.
需要说明的是,空调控制和换热设备控制可并发执行,图5所示的步骤S11至S14每日零点前执行一次,输出制冷设备当日的最优控制参数。It should be noted that the air conditioning control and the heat exchange equipment control can be executed concurrently. Steps S11 to S14 shown in FIG. 5 are executed once a day before zero o'clock to output the optimal control parameters of the refrigeration equipment on the day.
图9为本公开提供的再次确定并更新制冷设备当日的最优控制参数的流程示意图。FIG. 9 is a schematic diagram of the process of re-determining and updating the optimal control parameters of the refrigeration equipment on the day provided by the present disclosure.
如图9所示,在根据最优控制参数控制制冷设备运行的步骤(即,图5所示的步骤S15)之后,本公开的制冷设备控制方法还可以包括步骤S51至S53。As shown in FIG. 9, after the step of controlling the operation of the refrigeration equipment according to the optimal control parameters (ie, step S15 shown in FIG. 5), the refrigeration equipment control method of the present disclosure may further include steps S51 to S53.
在步骤S51,若空调当日的实际运行参数与空调当日的最优控制参数之间的误差超过第十阈值,则执行步骤S52;否则,结束本流程。In step S51, if the error between the actual operating parameters of the air conditioner on that day and the optimal control parameters of the air conditioner on that day exceeds the tenth threshold, step S52 is executed; otherwise, the process ends.
在步骤S52,再次确定空调当日的最优控制参数。In step S52, the optimal control parameters of the air conditioner for the day are determined again.
步骤S52的具体实现方式与步骤12至S14相同,在此不再赘述。The specific implementation of step S52 is the same as that of steps 12 to S14, and will not be repeated here.
在步骤S53,根据再次确定的空调当日的最优控制参数更新训练样本数据集。In step S53, the training sample data set is updated according to the re-determined optimal control parameters of the air conditioner on the day.
例如,若当日空调实际开启时刻和当日空调最优控制参数中空调开启时刻之间的误差超过10分钟,则需要重新预测空调当日的最优控制参数,并根据再次预测的空调当日的最优控制参数更新训练样本数据集,以提高制冷控制策略的及时应变能力,以及预测控制的实时性和精度。For example, if the difference between the actual air conditioner on time of the day and the air conditioner on time in the optimal control parameters of the day is more than 10 minutes, it is necessary to re-predict the optimal control parameters of the air conditioner for that day and use the predicted optimal control of the air conditioner for that day. The parameter updates the training sample data set to improve the timely adaptability of the refrigeration control strategy and the real-time performance and accuracy of the predictive control.
神经网络模型可以部署和运行在云端,在外部参数不断变化时,这些模型还可以不断进行实时或在线的训练,以不断提升预测精度,并能适应机房环境改变等异常情况而进行训练和调整。Neural network models can be deployed and run in the cloud. When external parameters are constantly changing, these models can also be continuously trained in real time or online to continuously improve prediction accuracy, and can be trained and adjusted to adapt to abnormal conditions such as changes in the computer room environment.
空调和换热设备可以实现故障倒换,相应地,本公开的制冷设备控制方法还可以包括:若当前运行的一种制冷设备故障且另一种制 冷设备正常,则关闭故障的制冷设备,并开启所述正常的制冷设备;以及若当前运行的两种制冷设备均故障,则在故障消除时,启动故障消除的制冷设备。也就是说,如果当前开启的制冷设备故障,则关闭该故障的制冷设备,并开启正常的制冷设备,等到故障消除时,再开启该制冷设备,并关闭另一个制冷设备。通过空调和换热器在故障时的互为备份的启动运行,可以避免机房异常高温的危险发生。The air conditioner and the heat exchange equipment can realize fault switching. Accordingly, the refrigeration equipment control method of the present disclosure may further include: if one type of refrigeration equipment currently running fails and the other type of refrigeration equipment is normal, turning off the failed refrigeration equipment and turning it on The normal refrigeration equipment; and if both of the two currently running refrigeration equipment are faulty, when the fault is eliminated, the refrigeration equipment with the elimination of the fault is activated. That is to say, if the currently opened refrigeration equipment fails, the faulty refrigeration equipment is turned off and the normal refrigeration equipment is turned on. When the fault is eliminated, the refrigeration equipment is turned on and the other refrigeration equipment is turned off. Through the mutual backup startup operation of the air conditioner and the heat exchanger in the event of failure, the danger of abnormally high temperature in the computer room can be avoided.
在根据最优控制参数控制制冷设备运行(即,图5所示的步骤S15)的过程中,本公开的制冷设备控制方法还可以包括:若当前室内温度小于第六阈值LT且制冷设备实际停机时长大于第七阈值,则根据当前获取的样本数据训练第二神经网络模型,所述样本数据包括室外温度、室内温度和制冷设备负荷。也就是说,在环境条件较好(例如,FSU和云端UME间有快速以太网互联,云端UME算力资源充足)的情况下,可以支持实时或在线模型训练。在机房内温度较低、制冷设备较长时间未运行时(比如,气温凉爽的季节、或者低温的夜晚),可以根据实时采集的室外温度、设备负荷、室内温度等数据,实时在线训练第二神经网络模型。In the process of controlling the operation of the refrigeration equipment according to the optimal control parameters (ie, step S15 shown in FIG. 5), the refrigeration equipment control method of the present disclosure may further include: if the current indoor temperature is less than the sixth threshold LT and the refrigeration equipment actually shuts down When the duration is greater than the seventh threshold, the second neural network model is trained according to the currently acquired sample data, the sample data including outdoor temperature, indoor temperature and refrigeration equipment load. That is to say, in the case of good environmental conditions (for example, there is a fast Ethernet interconnection between FSU and cloud UME, and cloud UME computing resources are sufficient), real-time or online model training can be supported. When the temperature in the computer room is low and the refrigeration equipment has not been running for a long time (for example, in a cool season or a low temperature night), you can perform real-time online training based on real-time data such as outdoor temperature, equipment load, and indoor temperature. Neural network model.
在根据最优控制参数控制制冷设备运行(即,图5所示的步骤15)之后,本公开的制冷设备控制方法还可以包括:将获取到的当日的样本数据和制冷设备当日的实际运行参数加入训练样本数据集,以便根据训练样本数据集训练第一神经网络模型和第三神经网络模型。通过将当日的样本数据和实际制冷控制结果添加到大数据集中,可以丰富训练集和测试集,对第一和第三神经网络模型进行在线训练,以提升模型的预测精度。After controlling the operation of the refrigeration equipment according to the optimal control parameters (ie, step 15 shown in FIG. 5), the refrigeration equipment control method of the present disclosure may further include: combining the acquired sample data of the day and the actual operation parameters of the refrigeration equipment on the day The training sample data set is added to train the first neural network model and the third neural network model according to the training sample data set. By adding the sample data and actual refrigeration control results of the day to the big data set, the training set and test set can be enriched, and the first and third neural network models can be trained online to improve the prediction accuracy of the model.
在通信网络中断情况下,FSU无法与UME通信,为了实现制冷设备的控制,FSU可以自动运行内置的温度启停控制算法,也可以接收并保存UME提前下发的制冷控制预案,并在本地运行从UME上复制的制冷联动控制算法。In the case of communication network interruption, FSU cannot communicate with UME. In order to realize the control of refrigeration equipment, FSU can automatically run the built-in temperature start-stop control algorithm, and can also receive and save the cooling control plan issued by UME in advance, and run it locally Refrigeration linkage control algorithm copied from UME.
相应地,在初始化阶段建立了第一神经网络模型、第二神经网络模型和第三神经网络模型之后,本公开的制冷设备控制方法还可以包括:将第一神经网络模型、第二神经网络模型和第三神经网络模型 部署在FSU上,以使在FSU与UME通信故障时,确定制冷设备当日的最优控制参数,并根据所述最优控制参数控制制冷设备运行。Correspondingly, after the first neural network model, the second neural network model, and the third neural network model are established in the initialization phase, the refrigeration equipment control method of the present disclosure may further include: combining the first neural network model and the second neural network model And the third neural network model is deployed on the FSU, so that when the FSU and the UME fail to communicate, the optimal control parameters of the refrigeration equipment of the day are determined, and the operation of the refrigeration equipment is controlled according to the optimal control parameters.
本公开的一个应用场景是:机房通信设备发热量小于10KW的基站类机房,其通常为运营商的数据、传输、交换类基站机房。原先机房制冷设备只有一台空调,为了降低空调能耗,在考虑了基站机房的外部环境、发热量和安装条件后,加装了智能热管设备(HPE)这种间接换热器,以通过空调和热管设备的联动控制来实现机房的解决方案。采用热管技术不需要机械制冷,室内外温差基本保持在6度左右,因而可以适用于全年90%以上的时间。同时,它的部件耗能远远低于传统的压缩机空调,耗能仅为原空调***的约1/5,因此可以大幅度节省空调耗电。An application scenario of the present disclosure is: a base station type computer room where the heat generated by the communication equipment in the computer room is less than 10 KW, which is usually a data, transmission, and switching type base station computer room of an operator. The original computer room refrigeration equipment only had one air conditioner. In order to reduce the energy consumption of the air conditioner, after considering the external environment, heat generation and installation conditions of the base station computer room, an indirect heat exchanger such as intelligent heat pipe equipment (HPE) was installed to pass the air conditioner. Linkage control with heat pipe equipment to realize the solution of the computer room. The use of heat pipe technology does not require mechanical cooling, and the temperature difference between indoor and outdoor is basically maintained at about 6 degrees, so it can be applied to more than 90% of the year. At the same time, the energy consumption of its components is much lower than that of the traditional compressor air conditioner, and the energy consumption is only about 1/5 of the original air conditioning system, so it can greatly save the power consumption of the air conditioner.
通常情况下,无论是机房的新建还是扩容,都会充分考虑机房的应用环境,以便选择合适的换热设备。通过热管和热交换器等间接换热设备,可以实现内外环境的隔离,适用范围较广,但是初始投资成本较高。在空气质量较好(没有盐雾、腐蚀性气体污染)、温度和湿度较低、用户有较强的定期维护能力的情况下,可以选择新风***作为直接换热设备。因此,本公开的另一个应用场景是:采用新风***和空调进行联动制冷的基站机房。Under normal circumstances, whether it is a new construction or expansion of a computer room, the application environment of the computer room will be fully considered in order to select the appropriate heat exchange equipment. Through indirect heat exchange equipment such as heat pipes and heat exchangers, the internal and external environments can be isolated, and the scope of application is wide, but the initial investment cost is relatively high. When the air quality is good (no salt spray or corrosive gas pollution), the temperature and humidity are low, and the user has strong regular maintenance capabilities, the fresh air system can be selected as the direct heat exchange equipment. Therefore, another application scenario of the present disclosure is: a base station room where a fresh air system and an air conditioner are used for linkage cooling.
根据本公开提供的制冷设备控制方案,可以基于大数据技术和神经网络技术,充分考虑到当前室内外温湿度、***负载等数据,结合负载预测、天气预报、同期历史样本数据等,通过神经网络的计算,***制冷设备负荷、室内温度,并输出制冷设备当日联动控制的最优预案,再与传统控制规则策略相结合,可以实现机房空调和换热设备的可预测的主动控制,达到优化控制、节能降耗的目的。According to the refrigeration equipment control scheme provided by the present disclosure, it can be based on big data technology and neural network technology, fully taking into account the current indoor and outdoor temperature and humidity, system load and other data, combined with load prediction, weather forecast, historical sample data of the same period, etc., through neural network Calculating, predicting the load and indoor temperature of the refrigeration equipment in advance, and outputting the optimal plan for the linkage control of the refrigeration equipment on the day, combined with the traditional control rule strategy, can realize the predictable active control of the air conditioning and heat exchange equipment in the computer room to achieve optimization The purpose of control, energy saving and consumption reduction.
由于实现了换热设备和空调的可预测的主动联控,显著减少了空调运行时间和启动次数;同时,可将机房设备的工作温度提高到可控的30-40℃的安全范围,进一步降低了制冷设备的能耗。初步估算,相比单空调制冷方式,通过空调和换热设备的主动预测式联控方案,每年可为通信基站节省耗电量将近1万度,平均耗电量减少40%,如果按照500万基站的10%比例计算,每年将减少电费50亿元、以及 135万吨碳排放,经济和社会效益显著。As the predictable and active joint control of heat exchange equipment and air conditioner is realized, the air conditioner running time and the number of starts are significantly reduced; at the same time, the working temperature of the equipment in the computer room can be increased to a controllable safety range of 30-40°C, further reducing The energy consumption of refrigeration equipment is improved. According to preliminary estimates, compared with the single air-conditioning refrigeration method, the active predictive joint control scheme of air-conditioning and heat exchange equipment can save nearly 10,000 kWh of power consumption for communication base stations each year, and the average power consumption is reduced by 40%. Calculated with a 10% ratio of base stations, annual electricity bills will be reduced by 5 billion yuan and 1.35 million tons of carbon emissions will be reduced, with significant economic and social benefits.
