Description

一种多媒体教室空调控制方法Multimedia classroom air conditioning control method

技术领域Technical field

本发明涉及一种空调的控制方法，特别是应用于多媒体教室的空调控制方法。The invention relates to a control method for an air conditioner, in particular to an air conditioner control method for a multimedia classroom.

背景技术Background technique

多媒体教室由多媒体计算机、液晶投影机、数字视频展示台、中央控制***、投影屏幕、音响设备等多种现代教学设备组成。随着教学设备的升级和改进及多媒体教室的普及，以往的大型的多媒体教室逐步的被中型的多媒体教室替代，这种中型的多媒体教室比普通的教室面积要大，但比大型的多媒体教室面积要小很多，不适合或没必要安装中央空调，因此，大匹数的室内挂机或柜机成为这类中型的多媒体教室的首选。近年来随着通风空调技术的发展，现有技术中，空调可以根据房间信息估计装置、房间信息估计方法简单且高精度地估计房间形状等的与房间有关的信息。估计与房间有关的信息的房间信息估计装置包括：摄像部件，拍摄估计对象的房间；人体检测部件，从由摄像部件拍摄到的图像检测人体，从而取得房间中的人体的位置；存在图生成部件，生成存在图，该存在图表示从不同的时刻拍摄到的多个图像检测到的人体的检测点的分布；以及估计部件，基于存在图来估计与房间有关的信息。人体检测部件能够从图像检测人的面部、头部、或者上半身，并基于图像中的面部、头部、上半身的位置以及大小，取得房间中的人体的位置。估计部件能够将与存在图中的检测点分布外接的多边形估计为房间的形状。即对于常规的房间来说，检测房间的形状、人物的数量分布均非技术上的难题。The multimedia classroom is composed of multimedia computers, LCD projectors, digital video display stands, central control systems, projection screens, audio equipment and other modern teaching equipment. With the upgrading and improvement of teaching equipment and the popularity of multimedia classrooms, the large-scale multimedia classrooms in the past have gradually been replaced by medium-sized multimedia classrooms. This medium-sized multimedia classroom is larger than the average classroom area, but larger than the large multimedia classroom area. It is much smaller, not suitable or necessary to install central air conditioning, so large indoor indoor hooks or cabinets become the first choice for this type of medium-sized multimedia classroom. In recent years, with the development of ventilation and air-conditioning technology, in the prior art, the air conditioner can estimate room-related information such as room shape simply and accurately based on the room information estimating device and the room information estimating method. A room information estimating device that estimates information related to a room includes: an image capturing unit that photographs a room to be estimated; a human body detecting unit that detects a human body from an image captured by the image capturing unit, thereby obtaining a position of a human body in the room; and a presence generating unit And generating a presence map indicating distributions of detection points of the human body detected from the plurality of images captured at different times; and estimating means for estimating information related to the room based on the presence map. The human body detecting component can detect the face, the head, or the upper body of the person from the image, and obtain the position of the human body in the room based on the position, size, and size of the face, the head, and the upper body in the image. The estimating component is capable of estimating a polygon circumscribing the distribution of the detection points in the existing map as the shape of the room. That is, for a conventional room, detecting the shape of the room and the number distribution of the characters are not technical problems.

国内现有技术中也曾公开一种空调器的控制方法，包括：控制空调器进入舒适控制模式；控制空调器将室内温度调整到设定温度；确定当前的PMV值；根据确定的PMV值对设定温度、相对湿度和风速进行调节。根据本发明的空调器的控制方法，能够使空调满足用户舒适性的要求，同时使空调可以节能运行，降低能耗。即先确定温度，再确定湿度，并根据控制方法来节能。A method for controlling an air conditioner is also disclosed in the prior art in the prior art, comprising: controlling an air conditioner to enter a comfort control mode; controlling an air conditioner to adjust an indoor temperature to a set temperature; determining a current PMV value; and determining a PMV value according to the determined Set the temperature, relative humidity and wind speed to adjust. According to the control method of the air conditioner of the present invention, the air conditioner can satisfy the requirements of the user's comfort, and at the same time, the air conditioner can be operated in an energy-saving manner and the energy consumption can be reduced. That is, determine the temperature first, then determine the humidity, and save energy according to the control method.

也有一种空调器的送风控制方法、***及空调器。其中，空调器的送风控制方法，包括：实时检测当前室内的人***置信息；实时检测当前室内的环境温度；获取空调器的设定温度；根据人***置信息、环境温度和设定温度，计算出空调器合适的送风角度和送风速度；控制空调器按照送风角度和送风速度运行。其实现了一种基于人***置信息的空调自适应的控制方法，使得空调器可以自动调整送风角度和送风速度，提供用户更舒适的智能风体验，提升用户的使用体验。进一步地，根据人***置信息，同时结合当前室内环境温度和空调器的设定温度，使得计算出来的送风速度更加准确，进一步地提升了用户的使用体验。但这种方法没有考虑到房间的面积对送风操作的影响。There is also a method, system and air conditioner for air supply control of an air conditioner. Among them, the air supply of the air conditioner The control method comprises: detecting the position information of the human body in the current room in real time; detecting the ambient temperature of the current indoor room in real time; obtaining the set temperature of the air conditioner; calculating the suitable air supply of the air conditioner according to the position information of the human body, the ambient temperature and the set temperature; Angle and air supply speed; control the air conditioner to operate according to the air supply angle and the air supply speed. The utility model realizes an air conditioner adaptive control method based on human body position information, so that the air conditioner can automatically adjust the air supply angle and the air supply speed, thereby providing a more comfortable intelligent wind experience for the user and improving the user experience. Further, according to the position information of the human body, combined with the current indoor ambient temperature and the set temperature of the air conditioner, the calculated air supply speed is more accurate, and the user experience is further improved. However, this method does not take into account the influence of the room area on the air supply operation.

也有一种空调器的控制方法、控制装置及空调器。其中控制方法包括以下步骤：接收安装在空调器上的超声波检测装置的范围检测信号；根据所述范围检测信号确定所述空调器的温度调控区域中的人员活动范围；根据所述人员活动范围控制所述空调器进行全方位送风或者分区域送风。其通过安装在空调器上的超声波检测装置检测空调器的温度调控区域中人员活动范围的大小，并根据检测到的人员活动范围选择、确定空调器的送风方式位全方位送风或者分区域送风。其公开了分区域送风的构思，但只停留在初步的构想阶段，没有给出具体的手段。There is also a method, a control device and an air conditioner for an air conditioner. The control method includes the steps of: receiving a range detection signal of the ultrasonic detecting device installed on the air conditioner; determining a range of human activities in the temperature control region of the air conditioner according to the range detecting signal; and controlling according to the range of the human activity The air conditioner performs air supply in all directions or air supply in a sub-area. The utility model detects the size of the human activity range in the temperature regulation area of the air conditioner through the ultrasonic detecting device installed on the air conditioner, and selects and determines the air supply mode of the air conditioner according to the detected range of the human activity, or the sub-area air supply or sub-area. Air supply. It disclosed the concept of sub-regional air supply, but only stayed in the preliminary concept stage, and did not give specific means.

现有技术中还出现了使用双温度传感器来检测人的体温的空调控制技术，其中一个传感器来感测热的温度，另一个检测是否低于某值，在这个现有技术中，出现了使用温度区域来调整空调运行的概念，但这种空调计算非常复杂，而且最重要的是无法适应于大面积的室内环境，也无法适用于人数众多的情况，因为人数众多时，温度检测就难以实现，而且很难根据体表的温度来控制送风参数。Air conditioning control techniques using dual temperature sensors to detect a person's body temperature have also appeared in the prior art, with one sensor sensing the temperature of the heat and the other detecting whether it is below a certain value. In this prior art, use has occurred. The temperature zone is used to adjust the concept of air conditioning operation, but this air conditioning calculation is very complicated, and the most important thing is that it cannot adapt to a large indoor environment, and it cannot be applied to a large number of cases. Because of the large number of people, temperature detection is difficult to achieve. And it is difficult to control the air supply parameters according to the temperature of the body surface.

现有技术中还有一种空调控制方法及基于红外检测的非人体热源滤除方法，滤除方法为将热源的温度与预设温度比较，若热源的温度高于预设温度，判断热源为高温热源，并滤除。其中，预设温度与室内环境温度和热源与空调的距离有关，室内环境温度越高、热源与空调的距离越近，预设温度越高；室内环境温度越低、热源与空调的距离越远，预设温度越低。本发明根据室内环境温度和热源与空调的距离确定预设温度，在热源温度高于根据室内环境温度和热源与空调的距离确定的预设温度的情况下，才判定热源为高温热源，并滤除。因而，本发明能够更加精确的滤除高温热源，防止误判，提高检测精度。这种技术提到了根据红外检测及离空调的距离的来判断是否是人体热源，这种方式已经开始了根据距离来判断送风条件，但其没考虑对于大面积室内温度调整时因距离而异的客观事实。In the prior art, there is also an air conditioning control method and a non-human body heat source filtering method based on infrared detection. The filtering method is to compare the temperature of the heat source with a preset temperature. If the temperature of the heat source is higher than the preset temperature, the heat source is determined to be a high temperature. Heat source and filter out. The preset temperature is related to the indoor ambient temperature and the distance between the heat source and the air conditioner. The higher the indoor ambient temperature, the closer the heat source is to the air conditioner, the higher the preset temperature; the lower the indoor ambient temperature, the farther the heat source is from the air conditioner. The lower the preset temperature. The invention determines the preset temperature according to the indoor ambient temperature and the distance between the heat source and the air conditioner, and determines that the heat source is high temperature heat when the heat source temperature is higher than the preset temperature determined according to the indoor ambient temperature and the distance between the heat source and the air conditioner. Source and filter out. Therefore, the present invention can more accurately filter out high temperature heat sources, prevent false positives, and improve detection accuracy. This technique refers to judging whether it is a human body heat source based on the distance of infrared detection and the distance from the air conditioner. This method has begun to judge the air supply condition according to the distance, but it does not consider the difference in distance for large-area indoor temperature adjustment. Objective facts.

现有技术中还出现了对于室内湿度的控制。其依据的是人的数量进行控制。当人数大于某个值时，控制空调执行除湿至最低阈值，但如果不大于某个阈值时，就上升到湿度的上限，但这种控制方式可能对小面积的房间适用，因为小的房间内，湿度检测精准，人数虽然变化，但只要不超过一个值，在小范围内变化是没有问题的，但对于大面积室内来说，很难准确得到湿度的确切值，而且单一根据人数是否超过某值来判断是否要除湿本身就不科学。其没有考虑复杂的环境变化。Control of indoor humidity has also appeared in the prior art. It is based on the number of people to control. When the number of people is greater than a certain value, the air conditioner is controlled to perform dehumidification to a minimum threshold, but if it is not greater than a certain threshold, it rises to the upper limit of humidity, but this control method may be applicable to a small-area room because of a small room The humidity detection is accurate, although the number of people changes, but as long as it does not exceed one value, there is no problem in a small range. However, for large-area indoors, it is difficult to accurately obtain the exact value of humidity, and whether the number is based on whether the number exceeds a certain number. It is not scientific to judge whether or not to dehumidify itself. It does not consider complex environmental changes.

另外，现有技术中，空调***的除湿方法包括：检测室内的环境温度；分别检测空调***的蒸发器的多个位置的多个温度；根据环境温度，计算环境温度下的目标湿度区间；根据目标湿度区间和环境温度得到露点温度区间；确定多个温度中的最低温度；根据最低温度与露点温度区间的上限值和下限值，调节所述空调的节流阀，以使最低温度在露点温度区间内。本发明的技术方案能够通过对节流阀的控制，使蒸发器温度的最小值在室内环境温度的人体舒适湿度对应的露点温度区间内，从而实现对室内环境湿度的控制，提升用户的使用体验。In addition, in the prior art, the dehumidification method of the air conditioning system includes: detecting an ambient temperature in the room; respectively detecting a plurality of temperatures of the plurality of positions of the evaporator of the air conditioning system; and calculating a target humidity interval at the ambient temperature according to the ambient temperature; The target humidity interval and the ambient temperature obtain a dew point temperature interval; determine a lowest temperature among the plurality of temperatures; adjust the throttle valve of the air conditioner according to an upper limit value and a lower limit value of the lowest temperature and the dew point temperature interval, so that the lowest temperature is at Dew point temperature range. The technical solution of the invention can control the throttle valve to make the minimum value of the evaporator temperature within the dew point temperature range corresponding to the comfortable temperature of the human body in the indoor environment temperature, thereby realizing the control of the indoor environment humidity and improving the user experience. .

但目前空调控制领域的研发主要集中在小面积室内的温度控制，这种控制通常为定值控制，即给出一个指定的目标温度，然后将整个室内的温度调节成该温度，这在小面积的室内是容易实现的，但对于中型面积的多媒体教室，尽管空调室内机的匹数增加，但定值控制的方法却很难达到预期效果，空调室内机因安装位置的局限性，其无法像小面积的室内那样，或大面积的室内多个出风口的中央空调那样均匀的送风或调节空气参数，只能从一点从近及远的向远处送风，而多媒体教室内热源情况复杂，所以很难做到定值控制，即使将室内的温度稳定在定值，室内的不同区域的温度差距也是必然客观存在的，空调器依据常规算法计算得出实际温度无法代表室内的客观情况。而且，目前在判断是否需要除湿操作时，往往根据的是经验参数或查表来确定，在复杂的环境下，这种判断会失效。 However, the current research and development in the field of air-conditioning control mainly focuses on the temperature control in a small-area room. This control is usually a fixed-value control, that is, giving a specified target temperature, and then adjusting the temperature of the entire room to the temperature, which is in a small area. The indoors are easy to implement, but for medium-sized multimedia classrooms, although the number of air-conditioned indoor units increases, the method of fixed value control is difficult to achieve the expected results. The air-conditioning indoor unit cannot be like the limitation of the installation position. In a small area indoors, or a large air conditioner in a large indoor air outlet, the air supply or air conditioning parameters can be evenly supplied from a point to a distance, and the heat source in a multimedia classroom is complicated. Therefore, it is difficult to control the fixed value. Even if the indoor temperature is stabilized at a fixed value, the temperature difference in different areas of the room must be objectively present. The air conditioner calculates according to the conventional algorithm that the actual temperature cannot represent the objective situation in the room. Moreover, at present, when judging whether a dehumidification operation is required, it is often determined based on empirical parameters or a look-up table, and in a complicated environment, such judgment may be invalid.

鉴于以上情况，为了提出更适合中型面积的多媒体教室的空气调节，提出本发明。In view of the above, the present invention has been made in order to propose air conditioning for a multimedia classroom that is more suitable for a medium-sized area.

多媒体教室的温差变化很大，这主要是因为多媒体教室的设备众多，由于每个人都使用一台计算机，而计算机发热对于室内环境的变化有显著影响，因此，可以将多媒体教室内的温度变化模糊的认为与教室内的人员数量和分布显著相关。而且，作为大温差变化的室内环境，除温度外，湿度也是影响人感觉舒适度的重要参数。The temperature difference in multimedia classrooms varies greatly.

更优选为，步骤S3包括：More preferably, step S3 comprises:

如果判断空调近距离送风区域无人，且空调远距离送风区域有人，如果是，则阶梯式降低室内温度至TL，且近距离送风区域送风时间短，空调远距离送风区域送风时间长。If it is judged that there is no air-conditioning area in the short-distance air-conditioning area, and there is someone in the air-conditioning long-distance air supply area, if it is, the indoor temperature is lowered to TL in a stepwise manner, and the air supply time in the short-distance air supply area is short, and the air-conditioning long-distance air supply area is sent. The wind is long.

本发明的有益效果是：The beneficial effects of the invention are:

1)本发明中，首次提出了对于利用温度区间和人的分布两个参数来控制室内温度的技术方案，如果判断空调近距离送风区域有人，且空调远距离送风区域无人，如果是，则阶梯式提高室内温度至TU，且近距离送风区域送风时间长，空调远距离送风区域送风时间短。如果判断空调近距离送风区域无人，且空调远距离送风区域有人，如果是，则阶梯式降低室内温度至TL，且近距离送风区域送风时间短，空调远距离送风区域送风时间长。1) In the present invention, a technical solution for controlling the indoor temperature by using two parameters of the temperature interval and the distribution of the person is proposed for the first time. If it is determined that there is a person in the air supply near the air supply area, and the air conditioning remote air supply area is unmanned, if Then, the indoor temperature is increased to TU in a stepwise manner, and the air supply time in the short-distance air supply area is long, and the air supply time in the air supply long-distance air supply area is short. If it is judged that there is no air-conditioning area in the short-distance air-conditioning area, and there is someone in the air-conditioning long-distance air supply area, if it is, the indoor temperature is lowered to TL in a stepwise manner, and the air supply time in the short-distance air supply area is short, and the air-conditioning long-distance air supply area is sent. The wind is long.

在上述的温度的控制下，室内温度根据室内人的分布进行调整，室温也一直在TU和TL之间进行摆动，只要人的分布情况稳定，则室温将阶梯式调整最终达到温度的上限值或下限值，或者停留在TL和TU之间的某一个值。如果在升温或降温的过程中，屋内的人员分布有所改变，则TS按ΔT的温差进行阶梯波动，但最终还是会达到温度的上限值或下限值，或者停留在TL和TU之间的某一个值。这样，空调就会根据用户发出的温度区间指令和教室内的实际情况进行调节空气。Under the above temperature control, the indoor temperature is adjusted according to the distribution of the indoor person, and the room temperature is always oscillated between TU and TL. As long as the distribution of the person is stable, the room temperature will be stepwise adjusted to reach the upper limit of the temperature. Or a lower limit, or a value that stays between TL and TU. If the distribution of people in the house changes during the process of heating or cooling, the temperature difference of TS is ΔT. Step fluctuations are made, but eventually the upper or lower temperature limit is reached, or a value between TL and TU. In this way, the air conditioner adjusts the air according to the temperature interval command issued by the user and the actual situation in the classroom.

2)对于除湿的步骤，首先，其是根据人数的变化而进行的除湿操作，只要人数变动，就先把室内的湿度直接降到湿度舒服区间的下限值，然后把检测到的R_实的值赋给R，下次再检测R_实与R比较，只要人数增加就把室内的湿度降到湿度舒服区间的下限值，但如果人数没有增加，或者减少了，那么目标湿度就会在当前的湿度值上阶梯上升，最后稳定在舒服区间的上限值。这种除湿的判断非常简单和易行，比传统的用多种难以获得的空气参数来确定是否除湿或除湿的目标湿度更易于执行。与现有技术相比，其将判断空调是否除湿由人数的绝对值变为相对变化值，这强调了空调控制的精准变化的思想。2) For the dehumidification step, firstly, it is a dehumidification operation according to the change of the number of people. As long as the number of people changes, the humidity in the room is directly lowered to the lower limit of the comfort interval of the humidity, and then the detected R _{is actually} The value is assigned to R. Next time, R _is compared with R. As long as the number of people increases, the indoor humidity is reduced to the lower limit of the humidity comfort interval. However, if the number of people does not increase or decrease, the target humidity will be at present. The humidity value rises stepwise and finally stabilizes at the upper limit of the comfort interval. This dehumidification judgment is very simple and easy, and it is easier to perform than the conventional use of various hard-to-obtain air parameters to determine whether the target humidity of dehumidification or dehumidification is performed. Compared with the prior art, it will judge whether the air conditioner is dehumidified from the absolute value of the number of people to the relative change value, which emphasizes the idea of accurate change of air conditioning control.

传统的方式中无法应对室内湿度因人的增加而在某一个时间段时迅速上升的情况，因为如果大量人集中进入室内，室内的湿度变化起初并不明显，但可能在之后的某个时间点突然上升，这就使空调压缩机的除湿工作负担很重，有时会因为超出空调的负荷而导致空调工作异常，而且除湿时风量减少，也不利于温度的控制。但本发明的中的湿度控制在大量的人进入室内之初就开始降低湿度，之后阶梯的上升湿度目标值与人的活动行为相一致，空调机在一个较长时间内间缓慢的调整室内湿度，而且保持室内湿度在一个舒服的区间内。In the traditional way, it is impossible to cope with the situation that indoor humidity rises rapidly at a certain time period due to the increase of people, because if a large number of people concentrate indoors, the humidity change in the room is not obvious at first, but may be at some later time. Sudden rise, which makes the dehumidification work load of the air conditioner compressor very heavy, sometimes the air conditioner works abnormally because of the load exceeding the air conditioner, and the air volume is reduced when dehumidifying, which is not conducive to temperature control. However, the humidity control in the present invention begins to reduce the humidity when a large number of people enter the room, and then the target value of the rising humidity of the step is consistent with the behavior of the person, and the air conditioner slowly adjusts the indoor humidity for a long period of time. And keep the indoor humidity in a comfortable interval.

以下将通过实施例对本发明进行详细描述。The invention will be described in detail below by way of examples.

首先，本发明中的空调器为现有技术中的空调器，如图1，一种典型的空调器包括压缩机1、四通阀2、室内换热器3、室外换热器5及节流部件6，所述压缩机1、四通阀2、室内换热器3、室外换热器5及节流部件6通过管道连接为密闭的空调***；本发明的特点是还包括冷媒加热器4、排气温度传感器7、室内换热器温度传感器8、室内环境温度传感器9及室外环境温度传感器10，所述冷媒加热器4设置在压缩机1的排气管上，所述排气温度传感器7设置在压缩机1的出口处，所述室内换热器温度传感器8和室内环境温度传感器9分别设置在室内换热器3处，所述室外环境温度传感器10设置在室外换热器5处。另外，人像检测的机器视觉***、湿度检测***(如干球检测)也是现有技术，这在背景技术部分有所介绍，不再详述。 First, the air conditioner in the present invention is an air conditioner in the prior art. As shown in FIG. 1, a typical air conditioner includes a compressor 1, a four-way valve 2, an indoor heat exchanger 3, an outdoor heat exchanger 5, and a section. The flow unit 6, the compressor 1, the four-way valve 2, the indoor heat exchanger 3, the outdoor heat exchanger 5, and the throttle member 6 are connected by pipes to be a closed air-conditioning system; the present invention is characterized by further including a refrigerant heater 4. An exhaust temperature sensor 7, an indoor heat exchanger temperature sensor 8, an indoor ambient temperature sensor 9, and an outdoor ambient temperature sensor 10, the refrigerant heater 4 being disposed on an exhaust pipe of the compressor 1, the exhaust gas temperature The sensor 7 is disposed at the outlet of the compressor 1, and the indoor heat exchanger temperature sensor 8 and the indoor ambient temperature sensor 9 are respectively disposed at the indoor heat exchanger 3, and the outdoor ambient temperature sensor 10 is disposed at the outdoor heat exchanger 5 At the office. In addition, the machine vision system for portrait detection and the humidity detection system (such as dry bulb detection) are also prior art, which are described in the background section and will not be described in detail.

另外，对于空调的送风***，现有的空调已经能实现室内小区域精准送风，比如格力空调有的机型采用了利用推出机构可伸出室内机身之外的导风板，其能控制风在上下范围内的吹送，而蜗舌下、出风口内的扫风叶风是控制左右送风的，两者的合用即可精准送风。In addition, for the air supply system of the air conditioner, the existing air conditioner can realize the accurate air supply in a small indoor area. For example, the Gree air conditioner has a wind deflector that can extend out of the indoor fuselage by using the push mechanism. The wind is controlled to blow in the upper and lower ranges, and the wind sweeping wind under the volute tongue and the air outlet is to control the left and right air supply, and the combination of the two can accurately supply the air.

为了对多媒体教室的室内温度、湿度更有利的控制，提出一种多媒体教室空调控制方法，包括以下步骤，In order to control the indoor temperature and humidity of the multimedia classroom more favorably, a multimedia classroom air conditioning control method is proposed, including the following steps.

S1：开始；这步骤可以在墙壁上的空调控制开关或者空调遥控手柄上完成，目的是将空调模式从常规的模式下切换到本发明提出的自动模式。S1: Start; this step can be done on the air conditioning control switch on the wall or the air conditioner remote control handle, in order to switch the air conditioning mode from the normal mode to the automatic mode proposed by the present invention.

S11：设定最高温度TU和最低温度TL；这里的最高温度TU代表着离空调较远的人在空调器控制室内为TU温度情况下认为舒服的温度上限，因为人离空调越远，空调吹出的同样温度的风，其感受与离空调近的人感觉必然不同，所以认为空调将室内的温度控制在TU的温度上限值时，是远离空高的人认为舒服的临界温度上了限值。相反，TL就是离空调近的人认为舒服的温度下限值，如果温度再低，可能离空调远的人不会有什么大的感觉，但离空调近的人将认为过于凉冷，难于忍受。使用者在S11中将最高温度TU和最低温度TL输入到空调的控制器内。S11: setting the maximum temperature TU and the lowest temperature TL; the highest temperature TU here represents the upper limit of the temperature that is considered to be comfortable when the person farther from the air conditioner is in the air conditioning control room for the TU temperature, because the farther away from the air conditioner, the air conditioner blows out The wind of the same temperature has a feeling that it is different from the person who is close to the air conditioner. Therefore, when the air conditioner controls the temperature of the room to the upper limit of the temperature of the TU, the critical temperature that is far from the height of the air is considered to be comfortable. . On the contrary, TL is the lower temperature limit that people close to the air conditioner think comfortable. If the temperature is lower, people who are far away from the air conditioner will not feel much, but people close to the air conditioner will think it is too cold and difficult to endure. . The user inputs the highest temperature TU and the lowest temperature TL into the controller of the air conditioner in S11.

S2：检测教室内实际人数R_实，教室内人的分布及检测当前实际温度T_实；这步骤的检测手段均为常规手段。S2: detecting the actual classroom _real number R, and detecting the distribution of current classroom person within _{the real} actual temperature T; step detecting means which are conventional means.

S5：返回步骤S2或结束。S5: Return to step S2 or end.

根据上述的步骤，使用者将用一个温度区域来控制室内的温度，从而满足多媒体教室的调温和调湿的需要。According to the above steps, the user will use a temperature zone to control the temperature in the room, thereby meeting the needs of temperature regulation and humidity control of the multimedia classroom.

对于步骤S3，可以进一步包括：For step S3, it may further include:

S341：也即判断了教室内空调近处无人，远离空调区域有人，因此，整个的送风将以满足远离空调区域的人为主，从而将空调的目标制冷温度设定为TS＝T_实-ΔT，没有一次性将目标制冷温度TS设定成为最低的TL是为了防止室内温度变化过快使人感觉不适应，而TS＝T_实-ΔT能使空调每次下调的温度区间很少，室内的人不会觉得温降过大。S341: Analyzing i.e. near the no air-conditioning in the classroom, away from the air-conditioning area was, therefore, will meet the entire blowing region of the person away from the main air-conditioning, so that the air conditioning target cooling temperature is set to TS = T _real - ΔT, the TL that does not set the target cooling temperature TS to the lowest at one time is to prevent the indoor temperature from changing too fast and makes people feel uncomfortable, and TS=T _real- ΔT can make the temperature range of the air conditioner to be lowered every time. People don't think the temperature drop is too big.

S343：将TS设置为TL；这是为了防止TS＝T_实-ΔT得到一个比TL还要小的值，所以也就是不会突破温度的下限，即使此时有人突然进入离空调近的区域，也不会感到不适应。S343: Set TS to TL; this is to prevent TS=T _real- ΔT from getting a value smaller than TL, so that it does not break through the lower limit of temperature, even if someone suddenly enters the area close to the air conditioner. I don't feel uncomfortable.

S344：空调在近距离送风区域送风时间短，空调在远距离送风区域送风时间长。这也是为了以远离空调的人为主的送风模式。S344: The air supply has a short air supply time in the short-distance air supply area, and the air supply has a long air supply time in the long-distance air supply area. This is also a mode of blowing air for people who are far away from air conditioners.

进一步，步骤S3包括：Further, step S3 includes:

S35：这时已经意判断室内没有人，一般这种情况下小面积的室内空调会进入休眠模式，但对于中型面积的多媒体教室，不应该进入休眠状态，因为当有人进入室内时，空调很难快速将温度调节成舒服的值。因此首先设定X＝0；这个参数用来控制程序的运行次数。S35: At this time, it is already determined that there is no one in the room. Generally, a small area of indoor air conditioner will enter a sleep mode in this case, but for a medium-sized multimedia classroom, it should not enter a dormant state, because when someone enters the room, the air conditioner is difficult. Quickly adjust the temperature to a comfortable value. So first set X=0; this parameter is used to control the number of times the program is run.

这里的S351和S352是为了提高空调外机的工作效率，现有技术中，会对空调外机的压缩机出气温度进行检测，如图1中排气温度传感器7。本申请根所据多媒体教室的客观情况，采用压缩机被动提高功率的方式来控制外机的工作。当室内无人时，降低室外机压缩机频率，这时排气温度传感器7检测到压缩机排气温度过低，将室外机风扇转速降低为第一速度，并保持第一预定时间，这是减少外机进风量，迫使室外机冷凝器内的制冷剂温度提高，在循环后压缩机排气的温度也进一步提高，这样压缩机的工作效率被动的提高。进一步，将室外机风扇转速降低为第二速度，并保持第二预定时间也是出于同样的目的，只是外机送风速率进一步下降。 Here, S351 and S352 are for improving the working efficiency of the outdoor unit of the air conditioner. In the prior art, the compressor outlet temperature of the outdoor unit of the air conditioner is detected, as shown in Fig. 1, the exhaust temperature sensor 7. According to the objective situation of the multimedia classroom, the application of the compressor passively increases the power to control the work of the external machine. When the indoors are unmanned, the outdoor unit compressor frequency is lowered. At this time, the exhaust temperature sensor 7 detects that the compressor exhaust temperature is too low, reduces the outdoor unit fan speed to the first speed, and maintains the first predetermined time, which is The air intake of the external unit is reduced, the temperature of the refrigerant in the condenser of the outdoor unit is increased, and the temperature of the exhaust gas of the compressor is further increased after the cycle, so that the working efficiency of the compressor is passively improved. Further, reducing the outdoor unit fan speed to the second speed and maintaining the second predetermined time is also for the same purpose, except that the external unit air supply rate is further decreased.

S353：设定X＝X+1；这时，将参数X增加1次。S353: Set X=X+1; at this time, the parameter X is increased by one time.

S354：判断X是否小于预设X’，如果是，返回S351，如果否，返回S31。也即如果循环了预定的次数，就需要再次对教室的人的情况检测。S354: It is judged whether X is smaller than the preset X', if yes, it returns to S351, and if not, it returns to S31. That is, if the predetermined number of times is cycled, it is necessary to detect the situation of the person in the classroom again.

需要说明的是，空调在室内无人时以节能的方式运行是本领域的常规手段，不局限于上述的方式。It should be noted that it is a conventional method in the art to operate the air conditioner in an energy-saving manner when no one is indoors, and is not limited to the above manner.

进一步，步骤S3包括：Further, step S3 includes:

S33：经过判断，说明教室内不论远近，都有人的分布，空调在近距离送风区域送风时间短，空调在远距离送风区域送风时间长，这样较远的区域可以得到更多的冷风，空调的目标制冷温度设定为TS＝K(TU+TL)/2，其中TL<TS<TU。这种情况下，空调的制冷温度只能是基于一个固定的值进行，但这个值是在用户输入的两个温度值之间。S33: After judging, it means that there are people in the classroom, no matter how far or near, there is a distribution of people. The air supply in the short-distance air supply area has a short air supply time, and the air-conditioning air supply time in the long-distance air supply area is long, so that the farther area can get more. For cold air, the target cooling temperature of the air conditioner is set to TS=K(TU+TL)/2, where TL<TS<TU. In this case, the cooling temperature of the air conditioner can only be based on a fixed value, but this value is between the two temperature values entered by the user.

可替换地，步骤S3包括：Alternatively, step S3 comprises:

S321：将空调的目标制冷温度设定为TS＝T_实+ΔT；这实质判断了空调送风区域中，近处有人，远处无人，此时不需过多考虑教室内远处的温度情况，以阶梯式的变温方法将室内温度提高到舒服温度的上限。S321: The target cooling temperature of the air conditioner is set to TS=T _real + ΔT; this substantially determines that there are some people in the air supply air supply area, and there is no one in the distance. At this time, it is not necessary to think too much about the distant temperature in the classroom. In the case, the indoor temperature is raised to the upper limit of the comfortable temperature by a stepwise temperature change method.

S323：将TS设置为TU；步骤S322，S323是防止空调升温超过TU这个上限值。S323: Set the TS to TU; in step S322, S323 is to prevent the air conditioner from rising above the upper limit of TU.

也可以认为，步骤S3包括：It can also be considered that step S3 includes:

如果判断空调近距离送风区域有人，且空调远距离送风区域无人，则阶梯式提高室内温度至TU，且近距离送风区域送风时间长，空调远距离送风区域送风时间短。If it is judged that there is someone in the air supply area at a short distance, and the air supply is far away from the air supply area, then the order is The ladder type increases the indoor temperature to TU, and the air supply time in the short-distance air supply area is long, and the air supply time in the air supply long-distance air supply area is short.

如果判断空调近距离送风区域无人，且空调远距离送风区域有人，则阶梯式降低室内温度至TL，且近距离送风区域送风时间短，空调远距离送风区域送风时间长。If it is judged that the air-conditioning short-distance air supply area is unmanned, and the air-conditioning long-distance air supply area is occupied, the indoor temperature is lowered to TL in a stepwise manner, and the air supply time in the short-distance air supply area is short, and the air supply time in the air-conditioning long-distance air supply area is long. .

在上述的温度的控制下，室内温度根据室内人的分布进行调整，室温也一直在TU和TL之间进行摆动，只要人的分布情况稳定，则室温将阶梯式调整最终达到温度的上限值或下限值，或者停留在TL和TU之间的某一个值。如果在升温或降温的过程中，屋内的人员分布有所改变，则TS按ΔT的温差进行阶梯波动，但最终还是会达到温度的上限值或下限值，或者停留在TL和TU之间的某一个值。这样，空调就会根据用户发出的温度区间指令和教室内的实际情况进行调节空气。Under the above temperature control, the indoor temperature is adjusted according to the distribution of the indoor person, and the room temperature is always oscillated between TU and TL. As long as the distribution of the person is stable, the room temperature will be stepwise adjusted to reach the upper limit of the temperature. Or a lower limit, or a value that stays between TL and TU. If the distribution of people in the house changes during the heating or cooling process, the TS will fluctuate according to the temperature difference of ΔT, but eventually it will reach the upper or lower limit of the temperature, or stay between TL and TU. A certain value. In this way, the air conditioner adjusts the air according to the temperature interval command issued by the user and the actual situation in the classroom.

对于除湿，现有技术中的除湿是根据每次检测的结果来调用除湿的参数或者决定不进行除湿，但对于多媒体教室来说，室内环境影响的因素很复杂，各种除湿的参数要么难于获取，要么无法反映客观的事实。根据多媒体教室的实际情况，本申请提出根据人的数量变化来判断是否需要除湿。因为人数的增多必然会带来室内湿度的变化，比如人的排汗，人的用水活动等，由于基本上人不会降低室内的湿度，因此可以认为，人数的增加会导致室内湿度的增加。单纯的人数值不能反映出湿度的变化，但人数的变化可以客观反映湿度的变化趋势。For dehumidification, the dehumidification in the prior art calls the parameter of dehumidification according to the result of each test or decides not to perform dehumidification, but for the multimedia classroom, the factors of the indoor environment influence are complicated, and various dehumidification parameters are difficult to obtain. Or it cannot reflect objective facts. According to the actual situation of the multimedia classroom, the present application proposes to determine whether dehumidification is required according to the change in the number of people. Because the increase in the number of people will inevitably bring about changes in indoor humidity, such as people's perspiration, people's water activities, etc., because basically people will not reduce the indoor humidity, it can be considered that the increase in the number of people will lead to an increase in indoor humidity. The simple human value does not reflect the change in humidity, but the change in the number of people can objectively reflect the trend of humidity.

步骤S4包括：Step S4 includes:

S421：设定目标湿度为湿度下限HL＝a％*RH，RH为饱合湿度；S421: setting the target humidity to a lower humidity limit HL=a%*RH, and RH is a saturated humidity;

S422：执行除湿预定时间，并检测当前教室内湿度H_实；S422: dehumidifying the predetermined time, and detects the current _real classroom humidity H;

S423：判断H_实是否等于a％*RH，如果是，执行S45，如果否，执行S422；S423: determining whether the _real H equals a% * RH, if yes, S45, and if not, performing S422;

S433：设定H＝b％*RH；S433: setting H=b%*RH;

S434：执行除湿预定时间； S434: Perform a dehumidification scheduled time;

S45：将R设置为R_实。S45: Set R to R _real .

对于除湿的上述步骤，首先，其是根据人数的变化而进行的除湿操作，只要人数变动，就先把室内的湿度直接降到湿度舒服区间的下限值，然后把检测到的R_实的值赋给R，下次再检测R_实与R比较，只要人数增加就把室内的湿度降到湿度舒服区间的下限值，但如果人数没有增加，或者减少了，那么就会在当前的湿度值上阶梯上升，最后稳定在舒服区间的上限值。与现有技术相比，其将判断空调是否除湿由人数的绝对值变为相对变化值，这强调了空调控制的精准变化的思想。For the above steps of dehumidification, firstly, it is a dehumidification operation according to the change of the number of people. As long as the number of people changes, the humidity in the room is directly lowered to the lower limit of the comfort interval of the humidity, and then the value of the detected R _{is actually} Assigned to R, the next time R _is compared with R, as long as the number of people increases the indoor humidity to the lower limit of the humidity comfort interval, but if the number does not increase, or decreases, then the current humidity value The upper step rises and finally stabilizes at the upper limit of the comfort interval. Compared with the prior art, it will judge whether the air conditioner is dehumidified from the absolute value of the number of people to the relative change value, which emphasizes the idea of accurate change of air conditioning control.

这种除湿的方式还有一个优点就是，传统的方式中无法应对室内湿度因人的增加而在某一个时间段时迅速上升的情况，因为如果大量人集中进入室内，室内的湿度变化起初并不明显，但可能在之后的某个时间点突然上升，这就使空调压缩机的除湿工作负担很重，有时会因为超出空调的负荷而导致空调工作异常，而且除湿时风量减少，也不利于温度的控制。但本发明的中的湿度控制在大量的人进入室内之初就开始降低湿度，之后阶梯的上升湿度目标值与人的活动行为相一致，空调机在一个较长时间内间缓慢的调整室内湿度，而且保持室内湿度在一个舒服的区间内。Another advantage of this method of dehumidification is that in the conventional method, it is impossible to cope with the situation that the indoor humidity rises rapidly at a certain time period due to the increase of people, because if a large number of people concentrate indoors, the humidity change in the room is not at first. Obvious, but may suddenly rise at a certain point in time later, which makes the dehumidification work load of the air conditioner compressor heavy, sometimes the air conditioner works abnormally because of the load exceeding the air conditioner, and the air volume is reduced when dehumidifying, which is not conducive to the temperature. control. However, the humidity control in the present invention begins to reduce the humidity when a large number of people enter the room, and then the target value of the rising humidity of the step is consistent with the behavior of the person, and the air conditioner slowly adjusts the indoor humidity for a long period of time. And keep the indoor humidity in a comfortable interval.

经过多个温度和湿度控制的循环，可以使室内温度和湿度适合多媒体教室的使用需要。如果需要跳出程序，可以手动的结束该控制方法。Through multiple cycles of temperature and humidity control, the room temperature and humidity can be adapted to the needs of the multimedia classroom. If you need to jump out of the program, you can manually end the control method.

实施例1：Example 1:

用户对多媒体教室进行温度设定，S1：开始；S11：设定最高温度TU＝24℃和最低温度TL＝21℃；S2：空调室内机检测教室内实际人数R_实、教室内人的分布及检测当前实际温度T_实＝30℃；S3：根据R_实、教室内人的分布，确定空调的目标制冷温度和送风模式；User multimedia classroom temperature setting, S1: Start; S11: setting a maximum temperature TU = 24 ℃ and the lowest temperature TL = 21 ℃; S2: the distribution of the actual number of air conditioning indoor unit detects _{the real} R classroom, classroom and wife detecting _{a real} current actual temperature T = 30 ℃; S3: the distribution of _{the solid} R, person within the classroom to determine a target refrigerant temperature and the air conditioner blowing mode;

其中，S31：判断空调近距离送风区域是否有人，发现有人存在，则进入S32，Among them, S31: judging whether there is someone in the air supply area of the air conditioner in close proximity, and if someone exists, it enters S32.

S32：判断空调远距离送风区域是否有人，发现远处没有人，则进入S321；S32: judging whether there is a person in the air supply long-distance air supply area, and if there is no person in the distance, the process proceeds to S321;

S321：将空调的目标制冷温度设定为TS＝30℃+0.5℃；S321: setting the target cooling temperature of the air conditioner to TS=30°C+0.5°C;

S344：空调在近距离送风区域送风时间长，空调在远距离送风区域送风时间短。S344: The air conditioner has a long air supply time in the short-distance air supply area, and the air conditioner supplies air in the long-distance air supply area. short time.

这种情况下，因为离空调室内机远的地方没有人，只需要满足离空调室内机近的人的舒适情况即可。由于室内温度高于舒适温度的最高值TU，所以将TS直接定为TU，需要说明的是，当室内温度稳定时，远离空调室内机的区域是高于舒适温度上限值的。但因为没有人处于远离的区域，所以对用户的体验并没有影响。In this case, since there is no one far from the air conditioner indoor unit, it is only necessary to satisfy the comfort of a person close to the air conditioner indoor unit. Since the indoor temperature is higher than the highest value TU of the comfort temperature, the TS is directly determined as the TU. It should be noted that when the indoor temperature is stable, the area away from the air conditioner indoor unit is higher than the upper limit of the comfort temperature. But because no one is in a faraway area, there is no impact on the user experience.

然后进入到步骤S4：Then proceed to step S4:

S41：判断R_实＝20是否大于R＝25，因为否，执行S431；S41: _solid judgment R = R = 20 is larger than 25, because no, performing S431;

S431：检测实际湿度H_实为50％*RH，设定目标湿度为H＝50％*RH+5％*RH＝55％*RH；S431: detecting the actual humidity H is _indeed 50% * RH, the target humidity is set to H = 50% * RH + 5 % * RH = 55% * RH;

S432：判断H是否大于湿度上限值70％*RH，RH为饱合湿度，因为否，执行S434；S432: determining whether H is greater than the upper limit of humidity 70% * RH, RH is saturated humidity, because no, perform S434;

S45：将R设置为R_实，即R_实＝20。S45: Set R to R _real , that is, R _real = 20.

实施例2：Example 2:

用户对多媒体教室进行温度设定，S1：开始；S11：设定最高温度TU＝24℃和最低温度TL＝21℃；S2：空调室内机检测教室内实际人数R_实、教室内人的分布及检测当前实际温度T_实＝22℃；S3：根据R_实、教室内人的分布，确定空调的目标制冷温度和送风模式；User multimedia classroom temperature setting, S1: Start; S11: setting a maximum temperature TU = 24 ℃ and the lowest temperature TL = 21 ℃; S2: the distribution of the actual number of air conditioning indoor unit detects _{the real} R classroom, classroom and wife detecting _{a real} current actual temperature T = 22 ℃; S3: the distribution of _{the solid} R, person within the classroom to determine a target refrigerant temperature and the air conditioner blowing mode;

S321：将空调的目标制冷温度设定为TS＝22℃+0.5℃；S321: setting the target cooling temperature of the air conditioner to TS=22°C+0.5°C;

S322：判断TS是否大于TU，TS＝22.5<24，所以TS的值就为22.5；S322: determining whether the TS is greater than TU, TS=22.5<24, so the value of TS is 22.5;

这种情况下，因为离空调室内机远的地方没有人，只需要满足离空调室内机近的人的舒适情况即可。但TS在实际室温T_实+ΔT后仍不能达室内温度高于舒适温度的最高值TU，这时如果一次性将TS设置到TU，人体将会感到一个剧烈温度变化的升温，采用以所以ΔT作为升温梯度，缓慢升温，最后当多次检测周期过后，当室内温度稳定时，离空调近的区域TS的温度就是TU。In this case, since there is no one far from the air conditioner indoor unit, it is only necessary to satisfy the comfort of a person close to the air conditioner indoor unit. But TS after the actual room temperature T + ΔT _real still can not reach the room temperature is higher than the highest value TU comfortable temperature, then if one-time TS is set to TU, the body temperature will feel a drastic change in temperature, using it to ΔT As the temperature rise gradient, the temperature is slowly increased. Finally, when the indoor temperature is stable after a plurality of detection cycles, the temperature of the region TS near the air conditioner is TU.

然后进入到步骤S4：Then proceed to step S4:

S41：判断R_实＝15是否大于R＝10，如果是，执行S421；S41: Analyzing R = 15 is larger than the _real R = 10, if yes, S421;

S421：设定目标湿度为湿度下限HL＝45％*RH，RH为饱合湿度；S421: setting the target humidity to a lower humidity limit HL=45%*RH, and RH is a saturated humidity;

S423：判断H_实是否等于45％*RH，如果是，执行S45；S423: determining whether or not equal to H _solid 45% * RH, if yes, S45;

S45：将R设置为R_实，即将R的值调整为当前的人数，R＝15。S45: Set R to R _real , that _is , adjust the value of R to the current number of people, R=15.

然后返回人数和人的分布和室内温度的检测。Then return the number and distribution of people and the detection of indoor temperature.

需要说明的是，当第二个循环检测时，只要人数不增加，空调在比对R_实与R的关系时，R_实将不大于R，这时就会将除湿的目标值变为湿度上限70％。Incidentally, when the second detection cycle, as long as the number does not increase, when compared to the relationship between air conditioning R and R of _{the solid,} the _solid is not greater than R R, then it will become the target humidity limit dehumidified 70%.

鉴于用户一般对温度有直观的判断，但对于湿度一般很少有判断的经验，本发明中湿度的舒适值由出厂时设定，但这并不排除可以人为设定湿度值。Since the user generally has an intuitive judgment on the temperature, but there is little experience in judging the humidity, the comfort value of the humidity in the present invention is set at the time of shipment, but this does not exclude that the humidity value can be artificially set.

实施例3：Example 3:

如果是空调近处没人而远处有人，这时就要调低空调的目标温度至TL，同样以梯度ΔT缓慢降温，最后将远离空调的区域控制在TL。需要说明的是，对于远离空调的区域的温度的检测有时需要在空调室内机外增加额外的检测装置。一般空调对室内温度的检测仅是在室内机进风口处进行检测，但这种检测有时会无法适应对大面积的室内的温度的检测。If there is no one near the air conditioner and there is someone in the distance, then the target temperature of the air conditioner should be lowered to TL, and the temperature will be slowly lowered by the gradient ΔT, and finally the area away from the air conditioner will be controlled at TL. It should be noted that the detection of the temperature of the area away from the air conditioner sometimes requires the addition of an additional detection device outside the indoor unit of the air conditioner. Generally, the air conditioner detects the indoor temperature only at the air inlet of the indoor unit, but such detection sometimes cannot adapt to the detection of the temperature in a large area.

对于温度的检测，也是强调人数的变化量，因为大面积的室内环境检测湿度的准确值是不容易的，所以强调人数变化对空调控制参数的影响。For the detection of temperature, it is also emphasized that the amount of change in the number of people, because the large-area indoor environment to detect the accurate value of the humidity is not easy, so emphasize the impact of the number of people on the air conditioning control parameters.
