具体实施方式Detailed ways
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application. , not all examples. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.
沥青搅拌站中，依靠人工经验控制冷料仓的冷料的上料速度的方式并不准确，容易存在误差，因冷料仓远离操作室，无法及时准确判断冷料仓的情况，在多种冷料同时上料时，操作就会受到限制，不容易做到各种冷料仓的上料速度的快速调整，容易出现上料不及时导致的缺料或者溢料等 情况，降低生产效率，增加损耗，从而增加成本。In asphalt mixing stations, the method of controlling the loading speed of cold material in the cold material silo based on manual experience is not accurate and prone to errors. Because the cold material silo is far away from the operation room, it is impossible to accurately judge the situation of the cold material silo in a timely manner. In various situations, When cold materials are loaded at the same time, the operation will be restricted. It is not easy to quickly adjust the feeding speed of various cold material bins. It is easy to cause shortage or overflow caused by untimely loading, which reduces production efficiency. Increase losses, thereby increasing costs.
另外，部分厂家冷料上料要求冷料仓固定，举例来说，假设冷料***有6个冷料仓，每个冷料仓储存不同的冷料，假设为6种冷料分别设置编号，即1#冷料、2#冷料、3#冷料、4#冷料、5#冷料和6#冷料，相应的，设置6个骨料仓，分别存放1#到6#骨料，缺少1#骨料时，启动1#冷料上料，缺少2#骨料时，启动2#冷料上料，依此类推。此种方法作业不灵活，需要冷料的编号与骨料的编号严格对应，同时要求1#冷料中的1#骨料的占比较大，否则可能会出现上错料的情况，可见，这种方式对冷料原材料和作业要求非常高，有时难以达到，控制可靠性不高。In addition, some manufacturers require cold material silos to be fixed when loading cold materials. For example, assume that the cold material system has 6 cold material silos, and each cold material warehouse stores different cold materials. Assume that the six cold materials are individually numbered. That is, 1# cold material, 2# cold material, 3# cold material, 4# cold material, 5# cold material and 6# cold material. Correspondingly, 6 aggregate bins are set up to store 1# to 6# aggregates respectively. , when the 1# aggregate is missing, start the 1# cold material loading, when the 2# aggregate is missing, start the 2# cold material loading, and so on. This method is inflexible and requires that the number of the cold material strictly corresponds to the number of the aggregate. At the same time, it is required that the 1# aggregate in the 1# cold material accounts for a large proportion, otherwise the wrong material may be loaded. It can be seen that this This method has very high requirements on cold material raw materials and operations, which are sometimes difficult to achieve and the control reliability is not high.
为此，本申请提供了一种冷料上料方法，准确实现各冷料仓的目标上料速度的自动控制，可以应用于沥青搅拌站中，由沥青搅拌站中的软件和/或硬件执行，示例性的，可以由控制器执行，该控制器可以控制上料控制***中的各部分，该控制器可以但不限于为可编程逻辑控制器(Programmable Logic Controller，PLC)或者单片机。To this end, this application provides a cold material loading method that accurately realizes automatic control of the target feeding speed of each cold material bin. It can be applied to asphalt mixing stations and executed by the software and/or hardware in the asphalt mixing stations. , exemplarily, it can be executed by a controller, which can control various parts of the material loading control system. The controller can be, but is not limited to, a programmable logic controller (Programmable Logic Controller, PLC) or a single-chip microcomputer.

图1是本申请提供的上料控制方法的流程示意图之一。Figure 1 is one of the flow diagrams of the feeding control method provided by this application.
如图1所示，本实施例提供一种上料控制方法，该方法至少包括：As shown in Figure 1, this embodiment provides a feeding control method, which at least includes:
步骤101、基于冷料数据模型，确定各冷料仓的目标上料速度；各冷料仓用于为各骨料仓供料；冷料数据模型中包含每个冷料仓的冷料中各骨料的含量。 Step 101. Based on the cold material data model, determine the target feeding speed of each cold material bin; each cold material bin is used to supply materials to each aggregate bin; the cold material data model includes each cold material in each cold material bin. Aggregate content.
目标上料速度即需要控制冷料仓达到的上料速度。The target feeding speed is the feeding speed that needs to be controlled by the cold material bin.
冷料中一般包含不同粒径的骨料，冷料中各骨料的含量可以理解为冷料所包含的各骨料的含量，示例性的，骨料的含量可以为骨料在冷料中的重量比例，也可以为骨料在冷料中的体积比例，等等。Cold materials generally contain aggregates of different particle sizes. The content of each aggregate in the cold material can be understood as the content of each aggregate contained in the cold material. For example, the content of aggregates can be the aggregate content in the cold material. The weight ratio can also be the volume ratio of aggregate in cold material, etc.
各骨料仓储存的骨料的粒径不同。实施中，冷料仓中储存冷料，可以将冷料仓的冷料输送到筛网(例如振动筛等)，然后由筛网将冷料细分成不同粒径的骨料，这些不同粒径的骨料可以进入到对应粒径的骨料仓中，从而实现冷料仓对骨料仓的供料。The particle sizes of aggregates stored in each aggregate bin are different. In practice, the cold material is stored in the cold material bin, and the cold material in the cold material bin can be transported to a screen (such as a vibrating screen, etc.), and then the screen will subdivide the cold material into aggregates of different particle sizes. These different particles Aggregates with different particle sizes can enter the aggregate silo with corresponding particle size, thereby realizing the cold material silo supplying the aggregate silo.
示例性的，如图2所示的上料控制***，包括上位机(例如计算机)，与上位机电连接的控制器，多个冷料仓和多个骨料仓，与多个冷料仓一一 对应连接的多个电机(图中以M示意)，以及与多个电机一一对应电连接的多个变频器，与多个冷料仓一一对应设置的多个上料皮带，与多个上料皮带对应的输送皮带，滚筒，提升机和振动筛。控制器与各变频器电连接。图中以6个冷料仓示意，并进行编号，分别为1号冷料仓、2号冷料仓、3号冷料仓、4号冷料仓、5号冷料仓和6号冷料仓，以6个骨料仓示意，并进行编号，分别为1号骨料仓、2号骨料仓、3号骨料仓、4号骨料仓、5号骨料仓和6号骨料仓。Exemplary, the material loading control system shown in Figure 2 includes a host computer (such as a computer), a controller electrically connected to the host machine, multiple cold material bins and multiple aggregate bins, together with the multiple cold material bins. A plurality of motors (indicated by M in the figure) connected in a one-to-one manner, a plurality of frequency converters electrically connected to a plurality of motors in a one-to-one correspondence, a plurality of feeding belts corresponding to a plurality of cold material silos, and multiple Each feeding belt corresponds to the conveyor belt, roller, elevator and vibrating screen. The controller is electrically connected to each frequency converter. The figure shows 6 cold material silos and they are numbered, namely No. 1 cold material silo, No. 2 cold material silo, No. 3 cold material silo, No. 4 cold material silo, No. 5 cold material silo and No. 6 cold material The bins are represented by 6 aggregate bins and are numbered, namely No. 1 aggregate bin, No. 2 aggregate bin, No. 3 aggregate bin, No. 4 aggregate bin, No. 5 aggregate bin and No. 6 aggregate bin. warehouse.
基于此，控制器可以通过控制变频器的频率，来控制电机的速度，进而控制冷料仓的上料速度，将冷料仓的冷料通过上料皮带、输送皮带、滚筒、提升机进入振动筛，通过振动筛的振动将冷料细分成不同粒径的骨料进入对应粒径的骨料仓。其中，冷料通过滚筒的出料口进入提升机。Based on this, the controller can control the speed of the motor by controlling the frequency of the frequency converter, thereby controlling the loading speed of the cold material bin, and passing the cold material in the cold material bin into vibration through the feeding belt, conveyor belt, roller, and elevator. Screen, through the vibration of the vibrating screen, the cold material is subdivided into aggregates of different particle sizes and enters the aggregate bin of corresponding particle sizes. Among them, the cold material enters the elevator through the discharge port of the drum.
实际应用中，在基于冷料数据模型，确定各冷料仓的目标上料速度之前，可以先获取冷料数据模型，示例性的，可以从本地获取预先存储的冷料数据模型，也可以通过网络下载云端存储的冷料数据模型，还可以获取人工手动输入的冷料数据模型。In practical applications, before determining the target feeding speed of each cold material bin based on the cold material data model, the cold material data model can be obtained first. For example, the pre-stored cold material data model can be obtained locally, or through The cold material data model stored in the cloud can be downloaded online, and the cold material data model input manually can also be obtained.
示例性的，上述冷料数据模型可以存储在本地的上位机中。控制器可以从上位机中获取冷料数据模型。For example, the above cold material data model can be stored in the local host computer. The controller can obtain the cold material data model from the host computer.
步骤102、基于各冷料仓的目标上料速度，控制各冷料仓上料。Step 102: Control the loading of each cold silo based on the target loading speed of each cold silo.
本实施例中，冷料数据模型能够提供冷料仓中的冷料所包含的各骨料的含量，能够准确体现出不同冷料的成分的差异，为冷料仓的上料速度的控制提供了数据基础，可以基于冷料数据模型，确定各冷料仓的目标上料速度，进而自动控制各冷料仓上料，解决了现有技术中依靠人工经验控制冷料仓的上料速度不准确的问题，实现了各冷料仓的上料速度的准确地自动独立控制，可靠性更高。并且，与人工经验控制冷料仓的上料速度相比，能够实时快速调整多个冷料仓的上料速度，控制更加及时，避免了出现缺料或者溢料等情况，从而提高了生产效率，减少了损耗，降低了成本。In this embodiment, the cold material data model can provide the content of each aggregate contained in the cold material in the cold material silo, can accurately reflect the differences in the composition of different cold materials, and provide a method for controlling the loading speed of the cold material silo. With the data foundation, the target feeding speed of each cold silo can be determined based on the cold material data model, and then the loading of each cold silo can be automatically controlled, which solves the problem of relying on manual experience in the existing technology to control the loading speed of the cold silo. Accurate questions realize accurate automatic independent control of the feeding speed of each cold material bin, with higher reliability. Moreover, compared with manual control of the feeding speed of cold silos, the feeding speed of multiple cold silos can be quickly adjusted in real time, and the control is more timely, avoiding shortages or overflows, thereby improving production efficiency. , reducing losses and lowering costs.
需要说明的是，本实施例的方案中，一个冷料仓可以为多个骨料仓供料，一个骨料仓也可以由多个冷料仓供料，无需要求某个冷料仓固定为某个骨料仓供料，基于冷料数据模型提供的冷料仓中的冷料所包含的各骨料的含量，就能够准确地进行上料速度的控制，更加可靠。It should be noted that in the solution of this embodiment, one cold silo can supply materials to multiple aggregate silos, and one aggregate silo can also be fed by multiple cold silos. There is no need to require a certain cold silo to be fixed as When an aggregate silo supplies materials, based on the content of each aggregate contained in the cold material in the cold silo provided by the cold material data model, the feeding speed can be controlled accurately and more reliably.
在示例性实施例中，基于冷料数据模型，确定各冷料仓的目标上料速度，如图3所示，具体实现方式可以包括：In an exemplary embodiment, based on the cold material data model, the target feeding speed of each cold material bin is determined, as shown in Figure 3. Specific implementation methods may include:
步骤301、获取各骨料仓的料位值。Step 301: Obtain the material level value of each aggregate bin.
参见图2，上料控制***中，每个骨料仓中可以设置料位计(图中在每个骨料仓内条状结构示意)，该料位计用于实时检测骨料仓中的料位值并发送至控制器。控制器可以基于料位计的检测结果，获取到骨料仓的料位值。Referring to Figure 2, in the feeding control system, a material level meter can be set in each aggregate bin (the strip structure in each aggregate bin is shown in the figure). The material level meter is used to detect the level in the aggregate bin in real time. The material level value is sent to the controller. The controller can obtain the material level value of the aggregate bin based on the detection results of the material level meter.
步骤302、基于冷料数据模型，计算各冷料仓的当前上料速度。本步骤的具体实现方式可以包括：获取各骨料仓的卸料速度和料位变化率；基于冷料数据模型、各骨料仓的卸料速度和料位变化率，计算各冷料仓的当前上料速度。Step 302: Calculate the current feeding speed of each cold material bin based on the cold material data model. The specific implementation of this step may include: obtaining the unloading speed and material level change rate of each aggregate bin; based on the cold material data model, the unloading speed and material level change rate of each aggregate bin, calculating the Current loading speed.
其中，获取各骨料仓的卸料速度时，具体的，可以基于各骨料仓对应的计量秤称量的骨料重量以及称量周期，得到骨料仓的卸料速度。实际应用中，参见图2，上料控制***中还包括计量秤，计量秤可以按照预设时长为称量周期，称量骨料仓的卸料时的骨料重量并发送至控制器。示例性的，可以将计量秤称量的骨料重量与称量周期的比值，作为骨料仓的卸料速度。如此，可以准确得到骨料仓的卸料速度。When obtaining the discharging speed of each aggregate bin, specifically, the discharging speed of the aggregate bin can be obtained based on the weight of the aggregate measured by the weighing scale corresponding to each aggregate bin and the weighing cycle. In practical applications, see Figure 2. The loading control system also includes a weighing scale. The weighing scale can weigh the weight of the aggregate during unloading of the aggregate bin according to the preset time period and send it to the controller. For example, the ratio of the weight of the aggregate measured by the weighing scale to the weighing cycle can be used as the discharging speed of the aggregate bin. In this way, the discharge speed of the aggregate bin can be accurately obtained.
控制器还可以基于料位计的检测结果，获取到骨料仓的料位变化率。料位变化率即当前时刻的料位值与上一时刻的料位值的差值与两个时刻的时间变化量的比值。The controller can also obtain the material level change rate of the aggregate bin based on the detection results of the material level meter. The material level change rate is the ratio of the difference between the material level value at the current moment and the material level value at the previous moment and the time change of the two moments.
其中，基于冷料数据模型、各骨料仓的卸料速度和料位变化率，计算各冷料仓的当前上料速度，具体可以包括：针对每个骨料仓，获取与骨料仓的骨料对应的冷料供应优先级，基于冷料供应优先级，确定为骨料仓供料的至少一个冷料仓中冷料的优先级最高的冷料仓，基于骨料仓的卸料速度和料位变化率以及优先级最高的冷料仓的冷料中骨料仓的骨料的含量，确定优先级最高的冷料仓的当前上料速度；其中，冷料供应优先级是按照各冷料仓的冷料中骨料仓的骨料的含量确定的，冷料仓的冷料中骨料仓的骨料的含量越大，冷料仓的冷料的优先级越高。Among them, based on the cold material data model, the unloading speed and material level change rate of each aggregate bin, the current feeding speed of each cold material bin is calculated. Specifically, it can include: for each aggregate bin, obtain the data related to the aggregate bin. The cold material supply priority corresponding to the aggregate is based on the cold material supply priority. The cold material silo with the highest priority among at least one cold material silo supplying the aggregate silo is determined based on the unloading speed of the aggregate silo. Based on the material level change rate and the aggregate content of the cold material in the cold material silo with the highest priority, the current feeding speed of the cold material silo with the highest priority is determined; among them, the cold material supply priority is based on each The cold material in the cold material bin is determined by the aggregate content in the aggregate bin. The greater the aggregate content in the cold material in the cold material bin, the higher the priority of the cold material in the cold material bin.

冷料数据模型中可以包含冷料、冷料中的各骨料及各骨料的含量的对应关系。如表1所示的冷料数据模型，冷料数据模型中可以包含多种冷料，每种冷料中各骨料的含量(重量比例或者体积比例)按照从大到小的顺序排列。冷料数据模型中，记录每种冷料的编号及对应的各骨料的编号和含量。表1中，以6种冷料示意，分别为1号到6号冷料，每种冷料包括1号骨料的含量、2号骨料的含量、3号骨料的含量、…….、min_1号骨料的含量Amin_1，其中，min_1表示含量最小的骨料，Amin_1表示含量最小的骨料的含量。又由于有的冷料以某几种骨料为主，这些骨料含量比较高，其它骨料的含量比较低，对上料速度的影响较小，因此，可以忽略这些骨料的影响，从而获取冷料数据模型中多种含量最高的骨料，即关注主要的一些骨料，以对冷料数据模型进行简化。简化后的冷料数据模型，如表2所示，以6种冷料示意，分别为1号到6号冷料，每种冷料对应三种含量最高的骨料。The cold material data model can include the corresponding relationship between the cold material, each aggregate in the cold material, and the content of each aggregate. As shown in the cold material data model shown in Table 1, the cold material data model can contain a variety of cold materials, and the content (weight ratio or volume ratio) of each aggregate in each cold material is arranged in order from large to small. In the cold material data model, the number of each cold material and the corresponding number and content of each aggregate are recorded. In Table 1, six kinds of cold materials are represented, namely cold materials No. 1 to No. 6. Each cold material includes the content of No. 1 aggregate, the content of No. 2 aggregate, the content of No. 3 aggregate, etc. , the content of min_1 aggregate Amin_1, where min_1 represents the aggregate with the smallest content, and Amin_1 represents the content of the aggregate with the smallest content. And because some cold materials are mainly composed of certain types of aggregates, the content of these aggregates is relatively high, and the content of other aggregates is relatively low, which has a small impact on the feeding speed. Therefore, the influence of these aggregates can be ignored, thus Obtain the aggregates with the highest content in the cold material data model, that is, focus on the main aggregates to simplify the cold material data model. The simplified cold material data model, as shown in Table 2, is represented by six types of cold materials, namely cold materials No. 1 to No. 6. Each cold material corresponds to the three highest-content aggregates.
基于此，可以针对每个骨料仓的骨料，从冷料数据模型中查找每个冷料仓的冷料中该骨料仓的骨料的含量并进行排序，基于排序结果确定骨料仓的骨料对应的冷料供应优先级，冷料仓的冷料中骨料仓的骨料的含量越大，冷料仓的冷料的优先级越高。Based on this, for the aggregates in each aggregate bin, the aggregate content of the cold materials in each cold bin can be found from the cold material data model and sorted, and the aggregate bin is determined based on the sorting results. The cold material supply priority corresponding to the aggregate is. The greater the aggregate content of the cold material in the cold material bin, the higher the priority of the cold material in the cold material bin.

参见表3，示意了1号骨料到6号骨料中，每种骨料对应的冷料供应优先级。表3中，以1号骨料为例，1号骨料对应的冷料供应优先级中，最优供应冷料(即优先级最高的冷料)为6号冷料，次优供应冷料(即优先级次高的冷料)为2号冷料，最后供应冷料(即优先级最低的冷料)为1号冷料，2号骨料对应的冷料供应优先级中，最优供应冷料为1号冷料，次优供应冷料为3号冷料，最后供应冷料为2号冷料，3号骨料对应的冷料供应优先级中，最优供应冷料为2号冷料，次优供应冷料为1号冷料，最后供应冷料为5号冷料，等等。基于此，示例性的，为1号骨料仓供1号骨料的冷料有6号冷料、2号冷料和1号冷料，则确定出优先级最高的6号冷料的冷料仓。Refer to Table 3, which shows the cold material supply priority corresponding to each aggregate from No. 1 aggregate to No. 6 aggregate. In Table 3, taking No. 1 aggregate as an example, in the cold material supply priority corresponding to No. 1 aggregate, the optimal cold material supply (that is, the cold material with the highest priority) is No. 6 cold material, and the second-best cold material supply (i.e. the cold material with the second highest priority) is cold material No. 2. The cold material supplied last (i.e. the cold material with the lowest priority) is cold material No. 1. Among the cold material supply priorities corresponding to aggregate No. 2, the best The cold material supplied is No. 1 cold material, the second best cold material supplied is No. 3 cold material, and the last cold material supplied is No. 2 cold material. Among the cold material supply priorities corresponding to No. 3 aggregate, the optimal cold material supply is 2. No. 1 cold material, the second best cold material supply is No. 1 cold material, the last cold material supplied is No. 5 cold material, and so on. Based on this, for example, the cold materials supplying No. 1 aggregate to the No. 1 aggregate bin include No. 6 cold materials, No. 2 cold materials and No. 1 cold materials, then the cold materials of No. 6 cold materials with the highest priority are determined. Silo.
示例性的，基于骨料仓的卸料速度和料位变化率以及优先级最高的冷料仓的冷料中骨料仓的骨料的含量，确定优先级最高的冷料仓的当前上料速度，具体可以包括：Illustratively, the current loading of the cold silo with the highest priority is determined based on the unloading speed and material level change rate of the aggregate silo and the aggregate content of the cold material in the cold silo with the highest priority. Speed, specifically can include:
第一步，基于骨料仓的卸料速度和优先级最高的冷料仓中骨料仓的骨料的含量，确定优先级最高的冷料仓对应的第一速度。The first step is to determine the first speed corresponding to the cold silo with the highest priority based on the unloading speed of the aggregate silo and the aggregate content of the aggregate silo in the cold silo with the highest priority.
具体的，可以基于骨料仓的卸料速度与优先级最高的冷料仓的冷料中骨料仓的骨料的含量的比值，确定优先级最高的冷料仓对应的第一速度。示例性的，可以将骨料仓的卸料速度与优先级最高的冷料仓中骨料仓的骨料的含量的比值，作为优先级最高的冷料仓对应的第一速度。也可以将骨料仓的卸料速度与优先级最高的冷料仓中骨料仓的骨料的含量的比值乘以设定的系数，作为优先级最高的冷料仓对应的第一速度。Specifically, the first speed corresponding to the cold silo with the highest priority can be determined based on the ratio of the unloading speed of the aggregate silo to the aggregate content of the cold silo in the cold silo with the highest priority. For example, the ratio of the unloading speed of the aggregate silo to the aggregate content of the aggregate silo in the cold silo with the highest priority can be used as the first speed corresponding to the cold silo with the highest priority. The ratio of the unloading speed of the aggregate silo to the aggregate content of the aggregate silo in the cold silo with the highest priority can also be multiplied by a set coefficient as the first speed corresponding to the cold silo with the highest priority.
第二步，基于骨料仓的料位变化率，确定优先级最高的冷料仓对应的第二速度。The second step is to determine the second speed corresponding to the cold silo with the highest priority based on the material level change rate of the aggregate silo.
具体的，可以将骨料仓的料位变化率，作为优先级最高的冷料仓对应的第二速度。也可以将骨料仓的料位变化率乘以设定的系数，作为最高的 冷料仓对应的第二速度。Specifically, the material level change rate of the aggregate silo can be used as the second speed corresponding to the cold silo with the highest priority. The material level change rate of the aggregate silo can also be multiplied by the set coefficient as the second speed corresponding to the highest cold silo.
第三步，基于第一速度和第二速度，确定优先级最高的冷料仓的当前上料速度。具体的，可以按照预设算法，基于第一速度和第二速度，确定优先级最高的冷料仓的当前上料速度。示例性的，可以将第一速度和第二速度求和，得到优先级最高的冷料仓的当前上料速度。也可以对第一速度和第二速度求均值，得到优先级最高的冷料仓的当前上料速度。The third step is to determine the current feeding speed of the cold silo with the highest priority based on the first speed and the second speed. Specifically, the current feeding speed of the cold silo with the highest priority can be determined based on the first speed and the second speed according to a preset algorithm. For example, the first speed and the second speed can be summed to obtain the current feeding speed of the cold silo with the highest priority. You can also average the first speed and the second speed to obtain the current loading speed of the cold silo with the highest priority.
步骤303、将各骨料仓的料位值与预设料位区间进行对比。Step 303: Compare the material level value of each aggregate bin with the preset material level interval.
实际应用中，可以预先设置各骨料仓对应的预设料位区间，各骨料仓对应的预设料位区间可以相同，也可以不同。由于各骨料仓对骨料的需求量可能不同，单独设置每个骨料仓对应的预设料位区间，控制更加准确。可以接收用户输入的预设料位区间，也可以根据生产配方对骨料的需求量自动确定预设料位区间。生产配方中一般包含需求的各骨料的比例，该骨料的比例能够表征骨料的需求量。例如，可以预先设置骨料的需求量与预设料位区间的对应关系，基于该对应关系确定骨料的需求量对应的预设料位区间。In practical applications, the preset material level intervals corresponding to each aggregate bin can be preset, and the preset material level intervals corresponding to each aggregate bin can be the same or different. Since the demand for aggregates in each aggregate bin may be different, setting the preset material level interval corresponding to each aggregate bin separately will make the control more accurate. It can receive the preset material level interval input by the user, and can also automatically determine the preset material level interval based on the demand for aggregates in the production formula. The production formula generally contains the required proportion of each aggregate, and the proportion of the aggregate can represent the demand for the aggregate. For example, the corresponding relationship between the demand for aggregate and the preset material level interval can be set in advance, and the preset material level interval corresponding to the demand for aggregate is determined based on the correspondence.
步骤304、基于各冷料仓的当前上料速度以及各对比的结果，确定各冷料仓的目标上料速度。Step 304: Determine the target feeding speed of each cold silo based on the current feeding speed of each cold silo and the results of each comparison.
其中，预设料位区间可以包括料位值依次增大的第一料位区间、第二料位区间和第三料位区间。那么，基于各冷料仓的当前上料速度以及各对比的结果，确定各冷料仓的目标上料速度，具体可以包括：The preset material level interval may include a first material level interval, a second material level interval and a third material level interval in which the material level value increases sequentially. Then, based on the current feeding speed of each cold silo and the results of each comparison, determine the target feeding speed of each cold silo, which may include:
若骨料仓的料位值位于第一料位区间内，将为骨料仓供料的至少一个冷料仓的当前上料速度增加，以得到为骨料仓供料的至少一个冷料仓的目标上料速度。若骨料仓的料位值位于第一料位区间内，说明骨料仓内的骨料较少，需要增加骨料，避免缺料，此时，可以增加当前上料速度。If the material level value of the aggregate silo is within the first material level interval, the current feeding speed of at least one cold silo supplying material to the aggregate silo is increased to obtain at least one cold silo supplying material to the aggregate silo. target feeding speed. If the material level value of the aggregate bin is within the first material level interval, it means that there is less aggregate in the aggregate bin and more aggregate needs to be added to avoid material shortage. At this time, the current feeding speed can be increased.
若骨料仓的料位值位于第二料位区间内，将为骨料仓供料的至少一个冷料仓的当前上料速度，作为为骨料仓供料的至少一个冷料仓的目标上料速度。若骨料仓的料位值位于第二料位区间内，说明骨料仓内的骨料比较合适，维持当前上料速度即可。If the material level value of the aggregate silo is within the second material level interval, the current feeding speed of at least one cold silo supplying material to the aggregate silo will be used as the target of at least one cold silo supplying material to the aggregate silo. Feeding speed. If the material level value of the aggregate bin is within the second material level range, it means that the aggregate in the aggregate bin is more suitable and the current feeding speed can be maintained.
若骨料仓的料位值位于第三料位区间内，将为骨料仓供料的至少一个冷料仓的当前上料速度减小，以得到为骨料仓供料的至少一个冷料仓的目 标上料速度。若骨料仓的料位值位于第三料位区间内，说明骨料仓内的骨料较多，为避免溢料，此时，可以减小当前上料速度。If the material level value of the aggregate silo is within the third material level interval, the current feeding speed of at least one cold material silo that supplies material to the aggregate silo is reduced to obtain at least one cold material that supplies material to the aggregate silo. The target loading speed of the warehouse. If the material level value of the aggregate bin is within the third material level interval, it means that there is more aggregate in the aggregate bin. In order to avoid overflow, the current feeding speed can be reduced at this time.
其中，可以按照预设步长，进行冷料仓的当前上料速度减小或者增加，预设步长的具体值可以根据实际情况设置，此处不做具体限定。当然也可以基于其它方式实现冷料仓的当前上料速度减小或者增加，此处不再一一列举。Among them, the current feeding speed of the cold material bin can be reduced or increased according to the preset step length. The specific value of the preset step length can be set according to the actual situation, and is not specifically limited here. Of course, the current feeding speed of the cold material bin can also be reduced or increased based on other methods, which will not be listed here.
本实施例中，综合考虑了冷料数据模型中提供的冷料中各骨料的含量，以及各骨料仓的卸料速度、料位值和料位变化率等多方面的因素，准确衡量各冷料仓的当前上料速度，并基于各骨料仓的料位值与预设料位区间的对比的结果，进而确定各冷料仓的目标上料速度，准确实现了冷料仓的上料速度的定量控制。In this embodiment, the content of each aggregate in the cold material provided in the cold material data model, as well as the unloading speed, material level value and material level change rate of each aggregate bin are comprehensively considered to accurately measure The current feeding speed of each cold silo is determined based on the comparison between the material level value of each aggregate silo and the preset material level interval, and the target feeding speed of each cold silo is determined to accurately realize the loading of the cold silo. Quantitative control of feeding speed.
在示例性实施例中，上料控制方法还可以包括：检测各冷料仓的料位值和/或表征是否可供料的供应状态；相应的，基于冷料供应优先级，确定为骨料仓供料的至少一个冷料仓中冷料的优先级最高的冷料仓，具体可以包括：基于冷料供应优先级，以及基于各冷料仓的料位值和/或表征是否可供料的供应状态，确定为骨料仓供料的可用的至少一个冷料仓中冷料的优先级最高的冷料仓，可用的冷料仓是料位值大于预设料位值和/或供应状态表征可供料的冷料仓。In an exemplary embodiment, the material loading control method may also include: detecting the material level value of each cold material bin and/or a supply status indicating whether material is available; accordingly, based on the cold material supply priority, determine the aggregate The cold silo with the highest priority of cold material in at least one cold silo supplied by the warehouse may include: based on the cold material supply priority, and based on the material level value of each cold silo and/or indicating whether material is available supply status, determine the cold silo with the highest priority of cold material in at least one available cold silo that supplies materials to the aggregate silo. The available cold silo has a material level value greater than the preset material level value and/or supply The status represents the cold silo available for feeding.
实际应用中，可以在冷料仓中设置料位计，用于检测冷料仓的料位值，若冷料仓的料位值大于预设料位值，说明该冷料仓的冷料足够，若冷料仓的料位值小于或者等于预设料位值，说明该冷料仓即将缺料。也可以在冷料仓的底部设置接近传感器，用于检测冷料仓的供应状态，若冷料仓已空，则无法供料，此时，接近传感器可以发出无物体接近的电信号给控制器，控制器可以确定冷料仓的供应状态为不可供料，以防止空转，否则，可以确定冷料仓的供应状态为可供料。In practical applications, a material level meter can be set up in the cold material bin to detect the material level value of the cold material bin. If the material level value of the cold material bin is greater than the preset material level value, it means that the cold material in the cold material bin is sufficient. , if the material level value of the cold material bin is less than or equal to the preset material level value, it means that the cold material bin is about to be short of material. A proximity sensor can also be set at the bottom of the cold silo to detect the supply status of the cold silo. If the cold silo is empty, the material cannot be supplied. At this time, the proximity sensor can send an electrical signal to the controller that no object is approaching. , the controller can determine that the supply status of the cold silo is unavailable to prevent idling, otherwise, it can determine that the supply status of the cold silo is available.
为保证连续生产，实施中，可以优先利用可用的冷料仓，即料位值大于预设料位值和/或供应状态表征可供料的冷料仓，为骨料仓进行供料，避免出现缺料的情况影响生产。当冷料仓小于或者等于预设料位值和/或不可供料时，可以自动切换至可用的冷料的优先级最高的冷料仓，例如，可以由骨料对应的冷料供应优先级中冷料的优先级最高(即最优供应冷料)的 冷料仓切换至冷料的优先级次高(即次优供应冷料)的冷料仓。In order to ensure continuous production, during implementation, the available cold material bins can be prioritized, that is, the cold material bins whose material level value is greater than the preset material level value and/or the supply status indicates the available materials, to supply materials to the aggregate bin to avoid The shortage of materials affects production. When the cold material bin is less than or equal to the preset material level value and/or is unavailable, it can automatically switch to the cold material bin with the highest priority of available cold material. For example, the cold material supply priority can be determined by the cold material supply priority corresponding to the aggregate. The cold material bin with the highest priority for cold materials (i.e., optimal cold material supply) is switched to the cold material bin with the second highest cold material priority (i.e., suboptimal cold material supply).
在示例性实施例中，基于各冷料仓的当前上料速度以及各对比的结果，确定各冷料仓的目标上料速度，还可以包括：In an exemplary embodiment, determining the target feeding speed of each cold silo based on the current feeding speed of each cold silo and the results of each comparison may also include:
第一步、获取骨料供应优先级，骨料供应优先级是按照各骨料仓的骨料的需求量确定的，骨料仓的骨料的需求量越大，骨料仓的骨料的优先级越高。The first step is to obtain the aggregate supply priority. The aggregate supply priority is determined according to the demand for aggregates in each aggregate bin. The greater the demand for aggregates in the aggregate bin, the higher the demand for aggregates in the aggregate bin. The higher the priority.
其中，各骨料仓的骨料的需求量可以是基于生产配方中各骨料的比例确定的。基于此，可以获取预先存储的生产配方，对生产配方中需求的各骨料的比例进行排序，基于排序结果，确定骨料供应优先级，骨料仓的骨料的需求量越大，骨料仓的骨料的优先级越高。The demand for aggregates in each aggregate bin can be determined based on the proportion of each aggregate in the production formula. Based on this, the pre-stored production formula can be obtained, and the proportion of each aggregate required in the production formula can be sorted. Based on the sorting results, the priority of aggregate supply is determined. The greater the demand for aggregates in the aggregate bin, the higher the aggregate demand. The higher the priority of the aggregates in the bin.
当然，也可以通过手动输入骨料供应优先级并存储。Of course, the aggregate supply priority can also be entered manually and stored.
第二步、确定各冷料仓的目标上料速度之和，得到总速度。The second step is to determine the sum of the target feeding speeds of each cold material bin to obtain the total speed.
第三步、若总速度大于预设的速度上限，基于骨料供应优先级，确定各骨料仓料中骨料的优先级最低的至少一个骨料仓。Step 3: If the total speed is greater than the preset speed limit, based on the aggregate supply priority, determine at least one aggregate bin with the lowest priority among the aggregate bins.
第四步、将为优先级最低的至少一个骨料仓供料的至少一个冷料仓的目标上料速度减小，以使得总速度小于或者等于预设的速度上限。The fourth step is to reduce the target feeding speed of at least one cold silo that supplies at least one aggregate silo with the lowest priority, so that the total speed is less than or equal to the preset speed upper limit.
实际应用中，上料控制***所能加载的负载是有限的，因此，需要在负载范围内，控制各冷料仓的目标上料速度。各冷料仓的目标上料速度之和能够反应上料控制***加载的总的负载，若总速度超过预设的速度上限，上料控制***将无法承受，在这种情况下，可以考虑按照骨料的需求量优先供应需求量大的骨料，减少需求量小的骨料的供应，基于此，设置上述骨料供应优先级，骨料仓的骨料的需求量越大，骨料仓的骨料的优先级越高，若确定的各冷料仓的目标上料速度的总速度大于预设的速度上限，则按照骨料供应优先级，将为优先级最低的至少一个骨料仓供料的至少一个冷料仓的目标上料速度减小，以使得总速度小于或者等于预设的速度上限，从而进一步保证连续生产。In practical applications, the load that the loading control system can load is limited. Therefore, it is necessary to control the target loading speed of each cold material bin within the load range. The sum of the target loading speeds of each cold silo can reflect the total load loaded by the loading control system. If the total speed exceeds the preset speed upper limit, the loading control system will not be able to bear it. In this case, you can consider The demand for aggregates gives priority to the supply of aggregates with large demand, and reduces the supply of aggregates with small demand. Based on this, the above-mentioned aggregate supply priority is set. The greater the demand for aggregates in the aggregate silo, the higher the demand for aggregates in the aggregate silo. The higher the priority of the aggregate, if the total speed of the determined target feeding speed of each cold silo is greater than the preset speed limit, then according to the aggregate supply priority, at least one aggregate silo with the lowest priority will be The target feeding speed of at least one cold silo of the supplied material is reduced so that the total speed is less than or equal to the preset speed upper limit, thereby further ensuring continuous production.
其中，将为优先级最低的至少一个骨料仓供料的至少一个冷料仓的目标上料速度减小，以使得总速度小于或者等于预设的速度上限时，具体的，可以先减小一个优先级最低的冷料仓的目标上料速度，若该一个优先级最低的冷料仓的目标上料速度减小到零，再减小一个优先级次低的冷料仓的 目标上料速度，依此类推，直至总速度小于或者等于预设的速度上限。如此，可以尽量使得骨料优先级高的优先供应。Among them, the target feeding speed of at least one cold silo that supplies at least one aggregate silo with the lowest priority is reduced so that the total speed is less than or equal to the preset speed upper limit. Specifically, it can be reduced first The target loading speed of a cold silo with the lowest priority. If the target loading speed of the cold silo with the lowest priority is reduced to zero, then reduce the target loading speed of the cold silo with the next lowest priority. speed, and so on, until the total speed is less than or equal to the preset speed upper limit. In this way, aggregates with high priority can be supplied first.
在示例性实施例中，可以根据用户的第一输入操作，确定冷料仓的冷料的种类。冷料因原材料可能来自地质不同的地区等因素，导致形成的冷料的成分有差异。实际应用中，可以预先获取各种冷料中各骨料的含量，以构建冷料数据模型。用户可以根据生产的需要，通过输入操作，选择冷料仓的冷料的种类，基于选择的冷料仓的冷料的种类，从冷料数据模型中获取冷料仓的冷料中各骨料的含量，生产更加灵活。In an exemplary embodiment, the type of cold material in the cold material bin may be determined according to the user's first input operation. Because the raw materials of cold materials may come from different geological areas and other factors, the composition of the cold materials formed will be different. In practical applications, the content of each aggregate in various cold materials can be obtained in advance to build a cold material data model. Users can select the type of cold material in the cold material silo through input operations according to production needs. Based on the selected type of cold material in the cold material silo, each aggregate in the cold material in the cold material silo is obtained from the cold material data model. content, production is more flexible.
在示例性实施例中，可以根据用户的第二输入操作，更新冷料仓的冷料中的不同骨料的含量。当冷料中的不同骨料的含量改变之后，骨料对应的冷料供应优先级也会发生改变。本实施例适用于现场冷料的种类较少的情况，骨料对应的冷料供应优先级中优先级最高的冷料没有，则可以利用与其它冷料仓的冷料的种类相同的冷料来替代，可以通过输入操作来更新用来替代的冷料中的不同骨料的含量，使用来替代的冷料成为骨料对应的冷料供应优先级中优先级最高的冷料。此时，多个冷料中放的是同一种冷料，但是，可以通过手动调整冷料数据模型中的骨料的含量来改变骨料对应的冷料供应优先级，以使装同一种冷料的不同冷料仓成为不同骨料的最优供应者，而不是同一骨料的最优供应者。In an exemplary embodiment, the contents of different aggregates in the cold material of the cold material bin may be updated according to the user's second input operation. When the content of different aggregates in the cold material changes, the cold material supply priority corresponding to the aggregate will also change. This embodiment is suitable for situations where there are fewer types of cold materials on site. If there is no cold material with the highest priority in the cold material supply priority corresponding to the aggregate, cold materials of the same type as those in other cold material bins can be used. To replace, you can update the content of different aggregates in the cold material used for replacement through input operations. The cold material used for replacement becomes the cold material with the highest priority in the cold material supply priority corresponding to the aggregate. At this time, the same cold material is placed in multiple cold materials. However, the cold material supply priority corresponding to the aggregate can be changed by manually adjusting the aggregate content in the cold material data model so that the same cold material is installed. Different cold silos of materials become the optimal suppliers of different aggregates, rather than the optimal suppliers of the same aggregate.
示例性的，冷料数据模型可以是通过如下方式构建的：将目标冷料仓中的冷料输送至多个骨料仓中，其中，冷料中各骨料分别进入对应的骨料仓中；检测冷料中各骨料在对应的骨料仓的储存量；基于冷料中各骨料的储存量，确定冷料中各骨料的含量；基于冷料中各骨料的含量，构建冷料数据模型。这里的目标冷料仓是当前待确定冷料中各骨料的含量的冷料仓。冷料仓和骨料仓均是沥青搅拌站中已有的，参见图2所示的沥青搅拌站中的上料控制***，基于该上料控制***，可以将冷料仓中的冷料输送至多个骨料仓中。如此，利用已有的沥青搅拌站就可以实现冷料数据模型的自动构建，无需其它专业设备，操作简单，具有很强的推广性。For example, the cold material data model can be constructed in the following manner: transport the cold material in the target cold material bin to multiple aggregate bins, where each aggregate in the cold material enters the corresponding aggregate bin respectively; Detect the storage amount of each aggregate in the cold material in the corresponding aggregate bin; determine the content of each aggregate in the cold material based on the storage amount of each aggregate in the cold material; build a cold material based on the content of each aggregate in the cold material Material data model. The target cold material bin here is the cold material bin where the content of each aggregate in the cold material is currently to be determined. Both the cold material silo and the aggregate silo are existing in the asphalt mixing plant. Refer to the material loading control system in the asphalt mixing plant shown in Figure 2. Based on this material loading control system, the cold material in the cold material silo can be transported to multiple aggregate bins. In this way, the existing asphalt mixing station can be used to automatically construct the cold material data model without the need for other professional equipment. The operation is simple and has strong generalizability.
基于以上实施例，将目标冷料仓中的冷料输送至多个骨料仓中，包括：将目标冷料仓中的冷料输送至筛网，通过筛网将冷料中的各骨料筛分至对应的骨料仓中。其中的筛网具有筛分功能，用于将冷料筛分成不同粒径的 骨料，然后分别存放到对应粒径的骨料仓中。这里的筛网可以为振动筛。如此，可以对冷料的各骨料进行准确区分。Based on the above embodiment, transporting the cold material in the target cold material bin to multiple aggregate bins includes: transporting the cold material in the target cold material bin to a screen, and screening each aggregate in the cold material through the screen. Divide into corresponding aggregate bins. The screen has a screening function and is used to screen the cold material into aggregates of different particle sizes, and then store them into aggregate bins of corresponding particle sizes. The screen here can be a vibrating screen. In this way, each aggregate of the cold material can be accurately distinguished.
其中，检测冷料中各骨料在对应的骨料仓的储存量，其具体实现方式可以包括：利用计量秤，检测冷料中各骨料在对应的骨料仓的重量；或者，利用料位计，检测冷料中各骨料在对应的骨料仓的料位值。Among them, detecting the storage amount of each aggregate in the cold material in the corresponding aggregate bin, the specific implementation method may include: using a weighing scale to detect the weight of each aggregate in the cold material in the corresponding aggregate bin; or, using the material The level meter detects the material level value of each aggregate in the cold material in the corresponding aggregate bin.
如图2所示的上料控制***，骨料仓对应有计量秤，可以按照顺序来依次将每个骨料仓的骨料卸放到计量秤上，通过计量秤来称量当前卸放的骨料的重量，作为储存量，即得到w 1，w 2，w 3，w 4，w 5，w 6，……w n，w n表示n个骨料仓中n号骨料仓的骨料的重量。也可以利用每个骨料仓中的料位计来检测骨料仓的骨料的料位值，作为储存量，即得到L 1，L 2，L 3，L 4，L 5，L 6……L n，L n表示n个骨料仓中n号骨料仓的骨料的料位值，料位值能够反应骨料的体积。 As shown in Figure 2, the loading control system has a weighing scale corresponding to the aggregate bin. The aggregates in each aggregate bin can be discharged to the weighing scale in sequence, and the currently discharged weight can be weighed by the weighing scale. The weight of the aggregate, as the storage capacity, is obtained as w 1 , w 2 , w 3 , w 4 , w 5 , w 6 ,... w n , w n represents the bone in the n aggregate bin in the n aggregate bins The weight of the material. The material level meter in each aggregate bin can also be used to detect the material level value of the aggregate in the aggregate bin, as the storage amount, that is, L 1 , L 2 , L 3 , L 4 , L 5 , L 6 ... ...L n , L n represents the material level value of the aggregate in the n aggregate bin in n aggregate bins, and the material level value can reflect the volume of the aggregate.
相应的，基于冷料中各骨料的储存量，确定冷料中各骨料的含量，其实现方式可以包括：将各骨料的储存量求和，得到总储存量；基于各骨料的储存量与总储存量的比值，确定各骨料的含量。Correspondingly, the content of each aggregate in the cold material is determined based on the storage capacity of each aggregate in the cold material. The implementation method may include: summing the storage capacity of each aggregate to obtain the total storage capacity; based on the storage capacity of each aggregate The ratio of storage capacity to total storage capacity determines the content of each aggregate.
实际应用中，可以直接将骨料的储存量与总储存量的比值，作为骨料的含量。In practical applications, the ratio of the aggregate storage capacity to the total storage capacity can be directly used as the aggregate content.
若骨料的储存量为骨料的重量，则冷料的n种骨料中第k种骨料的含量A k＝w k/(w 1+w 2+w 3+w 4+w 5+w 6+…+w n)，1≤k≤n，w k为第k种骨料的重量。基于此，骨料的含量为骨料的重量比例。 If the storage capacity of aggregate is the weight of aggregate, then the content of the kth aggregate in the n aggregates of the cold material A k =w k /(w 1 +w 2 +w 3 +w 4 +w 5 + w 6 +...+w n ), 1≤k≤n, w k is the weight of the kth aggregate. Based on this, the content of aggregate is the weight proportion of aggregate.
若骨料的储存量为骨料的料位值，冷料的n种骨料中第k种骨料的含量A k＝L k/(L 1+L 2+L 3+L 4+L 5+L 6+…+L n)，1≤k≤n，L k为第k种骨料的料位值。基于此，骨料的含量为骨料的体积比例。 If the storage capacity of aggregate is the material level value of the aggregate, the content of the kth aggregate in the n aggregates of the cold material A k =L k /(L 1 +L 2 +L 3 +L 4 +L 5 +L 6 +...+L n ), 1≤k≤n, L k is the material level value of the kth aggregate. Based on this, the content of aggregate is the volume proportion of aggregate.
当然，也可以将骨料的储存量与总储存量的比值乘以设定的系数之后作为骨料的含量。Of course, the ratio of the aggregate storage amount to the total storage amount can also be multiplied by a set coefficient as the aggregate content.
如此，通过沥青搅拌站中已有的计量秤和料位计，即可以准确得到每个骨料的储存量，进而准确得到冷料中每个骨料的含量。In this way, through the existing weighing scales and material level meters in the asphalt mixing station, the storage volume of each aggregate can be accurately obtained, and then the content of each aggregate in the cold material can be accurately obtained.

考虑到本实施例的主要目的是得到目标冷料仓中的冷料的各骨料的含量，因此，无需持续上料，只要能够准确地分析出冷料的各骨料的含量即可，如此，可以提高处理效率，基于此，本实施例提供了两种将冷料输送至多个骨料仓的方式，一种方式是，持续上料预设上料时长，然后就停止上料，另一种方式是，按照预设上料总量上料，达到该预设上料总量之后，则停止上料。对于按照预设上料总量上料的方式来说，可以预先称量该预设上料总量的冷料，放入冷料仓中。其中的预设上料时长和预设上料总量均可以根据经验统计进行设置，此处不做具体限定。Considering that the main purpose of this embodiment is to obtain the content of each aggregate of the cold material in the target cold material bin, there is no need to continue feeding materials, as long as the content of each aggregate of the cold material can be accurately analyzed, so , can improve processing efficiency. Based on this, this embodiment provides two ways to transport cold materials to multiple aggregate bins. One way is to continue loading for a preset loading time, and then stop loading. The other way is to continue loading for a preset loading time, and then stop loading. The first method is to load materials according to the preset total amount of materials, and stop loading after reaching the preset total amount of materials. For the method of loading materials according to the preset total amount of materials, the cold materials of the preset total amount of materials can be weighed in advance and put into the cold material bin. The preset feeding time and the preset total amount of feeding can be set based on empirical statistics, and there are no specific limitations here.
在示例性实施例中，基于冷料中各骨料的含量，构建冷料数据模型，其具体实现方式可以包括：将冷料中各骨料的含量排序；基于排序结果，构建冷料数据模型。参见表2所示的冷料数据模型，可以清晰地反应冷料中各骨料的含量排序，查询更加方便。In an exemplary embodiment, a cold material data model is constructed based on the content of each aggregate in the cold material. The specific implementation may include: sorting the content of each aggregate in the cold material; building a cold material data model based on the sorting results. .

Cold silo.
实际应用中，可以在多个冷料仓中储存多种冷料，基于此，可以针对每种冷料，确定冷料中各骨料的含量，基于多个冷料仓的冷料中各骨料的含量，构建冷料数据模型。如此，可以快速得到包含多种冷料中各骨料的含量的冷料数据模型，非常全面。In practical applications, a variety of cold materials can be stored in multiple cold material silos. Based on this, the content of each aggregate in the cold material can be determined for each cold material. Based on the content of each aggregate in the cold material in multiple cold material silos, The content of the cold material is determined and a cold material data model is constructed. In this way, a very comprehensive cold material data model containing the content of each aggregate in a variety of cold materials can be quickly obtained.

After obtaining the content of each aggregate in the No. 1 cold material in the No. 1 cold material bin, the No. 2 cold material bin is selected as the target cold material. warehouse, and transport the No. 2 cold material to multiple aggregate warehouses according to the preset loading time and preset loading speed. In this way, until all 6 cold material warehouses are selected, the cold materials in the 6 cold material warehouses are obtained. The content of each aggregate in the material is determined to complete the automatic construction of the cold material database.
下面以具体的应用场景为例，对本申请实施例提供的一种上料控制方法进行更加详细地介绍。Taking a specific application scenario as an example, a feeding control method provided by the embodiment of the present application will be introduced in more detail below.

The controller may be a PLC, and the host computer may be a computer. In addition, material level meters and proximity sensors can also be installed in the cold material bin. The host computer can store cold material data models, production recipes and preset material level intervals, and can also display production status in real time, such as the loading speed of the cold material bin. The preset material level intervals include the accelerated loading material level interval add_zone (i.e., the above-mentioned first material level interval), the fixed frequency material level interval static_zone (i.e., the above-mentioned second material level interval), and the decelerated loading material level interval sub_zone (i.e. The above third material level interval) and full material level stop_line and other material level marks. Among them, the full material level is used to trigger the full material prompt. In addition, the type of cold material for production can be selected from the cold material data model through the computer.
第一步、通过程序自动捕捉设备信息和设备状态。The first step is to automatically capture device information and device status through the program.
其中，设备状态包括皮带、滚筒、振动筛等的运行状态，若运行状态为开启状态，满足自适应上料前提条件。Among them, the equipment status includes the operating status of belts, rollers, vibrating screens, etc. If the operating status is on, the prerequisites for adaptive feeding are met.

In implementation, the unloading speed of the aggregate silo can be obtained based on the weight of the aggregate measured by the weighing scale corresponding to the aggregate silo and the elapsed time since the last weighing.
进一步的，还可以确定各冷料仓的目标上料速度之和，得到总速度。若总速度大于预设的速度上限，基于骨料供应优先级，确定多个骨料仓料中骨料的优先级最低的至少一个骨料仓。将为优先级最低的至少一个骨料仓供料的至少一个冷料仓的目标上料速度减小，以使得总速度小于或者等于预设的速度上限。Furthermore, the sum of the target feeding speeds of each cold material bin can also be determined to obtain the total speed. If the total speed is greater than the preset speed upper limit, based on the aggregate supply priority, at least one aggregate bin with the lowest priority of aggregate among multiple aggregate bins is determined. The target feeding speed of at least one cold silo feeding at least one aggregate silo with the lowest priority is reduced so that the total speed is less than or equal to a preset speed upper limit.
第五步、控制器根据最终的各冷料仓的目标上料速度，控制冷料仓对 应的变频器输出对应的频率。Step 5: The controller controls the frequency corresponding to the inverter output of the cold silo based on the final target loading speed of each cold silo.
第六步、变频器控制电机的输出，以调整冷料仓的上料速度。Step 6: The frequency converter controls the output of the motor to adjust the loading speed of the cold material bin.
