Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present application, and are not intended to limit the scope of the present application. Those skilled in the art can adapt it as desired to suit a particular application.
In the embodiment of the application, the application scene of the air conditioner in a market is taken as an example, and the principle of the application is described. First, division of a first area in a venue area is performed for a mall space. For the example, division of the location area may be performed by combining one or more factors such as building structure, functional area, commodity area, etc. If a certain brand of clothing occupies an independent space, the building structure space can be used as a first area; in another example, a larger open space contains multiple different merchandise stores, where the first area may be divided by the same merchandise store.
As can be seen from the principle of dividing the first area, the first area is an area with relatively independent space and functions, and when a merchant expects customers to browse shopping in the area, the indoor temperature of each place is not greatly different, so that the air conditioners of the first area can be uniformly controlled, and the room temperatures of each place in the first area are basically the same. However, for some positions of the first area, such as a cash desk, a fitting room, etc., local personnel concentration may occur during holidays, etc., at this time, the position in the first area may be further divided into the second area, so that the air conditioning equipment in the second area may be independently controlled as required.
After the division of the first area and the second area is completed, the corresponding relation between the first area and the second area, the air conditioner air outlet, the human body detection sensor and other devices can be established according to engineering drawings such as a building plan, a functional area design drawing, an air conditioner installation drawing, a human body detection sensor installation drawing and the like of a market.
First, referring to fig. 1, fig. 1 is a flowchart of main steps of an air conditioner control method according to an embodiment of the present application. As shown in fig. 1, the air conditioner control method according to the embodiment of the present application includes:
step S101: acquiring a person average value type in a place area;
step S102: and controlling the air output of the air outlet of the air conditioner in the place area according to the average person value type and the area temperature control difference value.
In step S101, the total number of people in the first area is detected by a human body detection sensor installed in the venue area, and the average value of the venue area is obtained from the area of the venue area. The method for calculating the average value of the people comprises the following steps:
and the average value type is obtained according to the value of the average value, and is sparse when the average value is less than or equal to 0.4 person/square meter in a certain market environment by way of example; when the average person value is greater than 0.4 person/square meter and less than or equal to 1.0 person/square meter, the average person value type is normal; when the average value is more than 1.0 person/square meter, the average value type is crowded.
In the embodiment of the application, the camera of the market monitoring system is preferentially used for intercepting the image in the video at fixed time, detecting the human body in the image, determining the position of each person and further obtaining the total number of people in the place area. The method for detecting the human body in the image can adopt any known technology, and the application is not limited to the method. As an example, the implementation can be performed by adopting an AdaBoost algorithm, a Fast R-CNN network and the like. Those skilled in the art can select an appropriate method to implement according to the actual situation.
In addition, the detection of the number of people in the place area can be performed by one of other human body detection sensors such as millimeter wave radar sensors, ultrasonic sensors, infrared sensors and the like. Further, the human detection can be performed by adopting a mode of combining a plurality of human detection sensors. For example, in a mall, people in a place area can be detected together through video images collected by a monitoring camera and a millimeter wave radar sensor on an air outlet of an air conditioner.
In step S102, firstly, a regional temperature control difference is obtained, a local current temperature value near an air outlet is obtained through a temperature sensor installed at the air outlet of the air conditioner, an average value is taken for all local current temperature values in the region, a regional current temperature value is obtained, and the regional current temperature value is compared with a preset regional preset temperature to obtain a regional temperature control difference.
Specifically, when the air conditioner works in the cooling mode, if the current temperature of the area is less than or equal to the preset temperature of the area, the temperature control difference value of the area is invalid (the air conditioner can not need to continue cooling, and only needs to be controlled according to the default mode of the air conditioner at this time, such as working in a standby state with low power consumption); if the current temperature of the region is greater than the preset temperature of the region, the region temperature control difference is as follows:
zone temperature control difference = zone current temperature-zone preset temperature
When the air conditioner works in the heating mode, if the current temperature of the area is greater than or equal to the preset temperature of the area, the temperature control difference value of the area is invalid (the air conditioner can not continue heating, and at the moment, the air conditioner only needs to control according to the default mode of the air conditioner, such as the air conditioner works in the standby state with low power consumption), the current temperature of the area is less than the preset temperature of the area, and the temperature control difference value of the area is:
zone temperature control difference = zone preset temperature-zone current temperature
Next, the air outlet control of the air conditioner air outlet when the average person value types are sparse, normal, and crowded will be described in detail with reference to fig. 2 and 3, respectively, to explain step S102.
As shown in fig. 2, when the site area is a first area and the first person average value type is sparse, no matter the air conditioner is in a cooling mode or a heating mode, the air output control of the air outlet of the air conditioner in the first area is:
when the temperature control difference value delta T of the first area is smaller than or equal to a first temperature difference threshold value T1, namely delta T is smaller than or equal to T1, setting the first air output as a first air output gear;
when the temperature control difference value delta T of the first area is larger than a first temperature difference threshold value T1 and the temperature control difference value of the first area is smaller than or equal to a second temperature difference threshold value T2, namely T1 is smaller than delta T and smaller than or equal to T2, setting the first air output as a second air output gear;
when the temperature control difference value delta T of the first area is larger than the second temperature difference threshold value T2, namely delta T is larger than T2, the first air output is set to be a third air output gear.
At this time, under the condition that the comfort of personnel is hardly affected, the air outlet quantity of the air outlet of the air conditioner can be reduced in a few areas of personnel in a market in a targeted manner, so that the air conditioner load is reduced, and the effects of energy conservation and emission reduction are achieved. As an example, the first temperature difference threshold T1 may be set to 1 ℃, and the second temperature difference threshold T2 may be set to 2 ℃.
As shown in fig. 2, when the site area is the first area and the first person average value type is normal, no matter the air conditioner is in the cooling mode or the heating mode, the air output control of the air outlet of the air conditioner in the first area is:
when the temperature control difference value delta T of the first area is smaller than or equal to a first temperature difference threshold value T1, namely delta T is smaller than or equal to T1, setting the first air output as a second air output gear;
when the temperature control difference value delta T of the first area is larger than a first temperature difference threshold value T1 and the temperature control difference value of the first area is smaller than or equal to a second temperature difference threshold value T2, namely T1 is smaller than delta T and smaller than or equal to T2, setting the first air output as a third air output gear;
when the temperature control difference value delta T of the first area is larger than the second temperature difference threshold value T2, namely delta T is larger than T2, the first air output is set to be a fourth air output gear.
At the moment, the average person value type is normal, and the influence of personnel on the regional environment temperature is temporarily not considered. The air outlet of the air conditioner is improved, the refrigerating/heating effect of the air conditioner can be improved, the regional environment temperature can reach the preset regional temperature rapidly, and the customer is ensured to be in a comfortable regional environment.
Continuing to read FIG. 3, when the venue area is a first venue area and the first people average type is crowded, then it is often desirable to consider the effect of people on the temperature of the venue environment.
When the air conditioner is in a refrigerating mode, people dissipate heat, the air conditioner can be regarded as a heat source, and the effect of the air conditioner is opposite to that of the air conditioner, so that the influence of the people on the regional environment is partially counteracted, and the air outlet of the air conditioner can be increased relative to the air outlet control when the average value type of the people is normal. At this time, the control method of the air outlet air volume of the air conditioner comprises the following steps:
when the temperature control difference value delta T of the first area is smaller than or equal to a first temperature difference threshold value T1, namely delta T is smaller than or equal to T1, setting the first air output as a third air output gear;
when the temperature control difference value delta T of the first area is larger than a first temperature difference threshold value T1 and the temperature control difference value delta T of the first area is smaller than or equal to a second temperature difference threshold value T2, namely T1 is smaller than delta T and smaller than or equal to T2, setting the first air output as a fourth air output gear;
when the temperature control difference value of the first area is larger than the second temperature difference threshold value T2, namely delta T is larger than T2, setting the first air output as a fifth air output gear.
When the air conditioner is in a heating mode, people dissipate heat, the temperature of the regional environment can be raised as the same as the air conditioner, and the air outlet of the air conditioner can be reduced for energy conservation and environmental protection compared with the air outlet control when the average value type of the people is normal. At this time, the control method of the air outlet air volume of the air conditioner comprises the following steps:
when the temperature control difference value delta T of the first area is smaller than or equal to a first temperature difference threshold value T1, namely delta T is smaller than or equal to T1, setting the first air output as a first air output gear;
when the temperature control difference value delta T of the first area is larger than a first temperature difference threshold value T1 and the temperature control difference value of the first area is smaller than or equal to a second temperature difference threshold value T2, namely T1 is smaller than delta T and smaller than or equal to T2, setting the first air output as a second air output gear;
when the temperature control difference value delta T of the first area is larger than the second temperature difference threshold value T2, namely delta T is larger than T2, the first air output is set to be a third air output gear.
In one scenario of the embodiment of the application, the people average value type of the first area is normal, and the situation of centralized queuing and checkout of people occurs in the second area in the first area, so that the local people average value type of the second area becomes crowded. At this time, in order to improve the comfort level of the customers in the second area, the air volume of the second area can be controlled independently, so as to compensate the influence caused by the regional environmental temperature due to the local personnel concentration, and specifically, the method comprises the following steps:
when the second average person value type (average person value type of the second area) is crowded, and the air conditioner works in a refrigeration mode, the second air outlet quantity (air outlet quantity of the second area) is increased by one gear, the influence of personnel heat dissipation on the area temperature is compensated, and the customer comfort level is improved. For example, when the first region temperature control difference is less than or equal to the first temperature difference threshold, the second air output is changed from the third air output gear to the fourth air output gear.
When the second people average value type is crowded, and the air conditioner works in a heating mode, the second air output is reduced by one gear, so that the heating effect of people is fully utilized, the effects of energy conservation and consumption reduction are achieved, meanwhile, the situation that the temperature of a region is raised too fast can be avoided, and the waiting in line is reduced. For example, when the first region temperature control difference is less than or equal to the first temperature difference threshold, the second air output is changed from the third air output gear to the second air output gear.
Further, the application also provides an air conditioner control system, which comprises a human body detection sensor and a server. The human body detection sensor is used for detecting the number of people in the place area; the server comprises a memory and a processor, wherein the memory is used for storing a plurality of program codes, and the program codes realize the air conditioner control method of the method embodiment when being executed by the processor. Optionally, the human body detection sensor is a monitoring camera and/or a millimeter wave radar sensor arranged in an air outlet of an air conditioner and independently arranged in a public place, the server is a local intelligent home server or a cloud intelligent home sensor, and data interaction can be performed among the server, the air conditioner and the monitoring camera through wireless networks such as Wi-Fi, 4G/5G and/or wired networks such as Ethernet.
Further, the present application provides a central air conditioner including a human body detection sensor, a memory, and a processor. The human body detection sensor is used for detecting the number of people in the place area; the memory is used for storing a plurality of program codes, and the processor may be configured to execute instructions to implement the air conditioner control method of the above-described method embodiment.
