[0002] In the field of construction, the problem of inaccurate energy-saving regulation is common. Since most current sensor data monitoring and intelligent analysis are not comprehensive enough, the energy management systems of many buildings cannot accurately control energy consumption. For example, in office scenarios, the central air-conditioning system may not be able to operate intelligently when some areas are occupied and some areas are unoccupied. For the sake of comfort, the system can only be kept on, resulting in energy waste. Such problems not only increase energy costs, but also have a negative impact on the environment.

[0003] The current operation mode of intelligent control is: use a single infrared human body sensor, thermopile sensor, radar sensor to detect whether there is someone in a single area, and control the switch status of lighting, air conditioning, etc. according to the status of the person. When the person leaves this area, only the air conditioning and lights can be turned off. However, after the person leaves this area, if he is only in the area next to the area, in general, the person is still in the building space and there is a possibility of returning to the area. If the person returns to the area in a short time, the lighting and air conditioning need to be restarted, resulting in energy loss. Summary of the invention

[0028] See also Figure 1 and Figure 2 The embodiment of the present invention provides a building energy-saving control method based on edge intelligent control, which is applied to an edge intelligent control device 10. The building space includes multiple areas. The edge intelligent control device 10 is arranged in the building space. Each of the areas is provided with a millimeter wave radar 20, an air conditioner 30 and a lighting device 40 that are communicatively connected to the edge intelligent control device 10. The areas include adjacent first areas and second areas. The building space may be an office building, which may include multiple areas such as an office area, a meeting area and a rest area. The edge intelligent control device 10 is arranged in the building space, and can receive and send data nearby to control other devices that are communicatively connected to it, such as a millimeter wave radar 20, an air conditioner 30 for adjusting indoor temperature and humidity, and a lighting device 40 for adjusting indoor lighting. The millimeter wave radar 20 can be used to scan the interior of the building space to obtain spatial information of each area, object information in the space and status information of personnel. The spatial information may include boundary shape information, volume information, and area information. The object information may include object shape information and object position information. The method includes S100~S200.

[0029] S100: Based on the scanning result of each millimeter-wave radar, obtain status information of people in each area.

[0030] Based on the scanning results of each millimeter-wave radar, the status information of the people in each area is obtained. The millimeter-wave radars set in each area perform real-time and dynamic scanning of the space within its scanning range to obtain the status information of the people in the corresponding area and transmit it to the edge intelligent control device in real time. The status information of the people may include whether there are people, the current location information of the people, the movement trajectory information composed of the location information of the people within a certain period of time, the posture information of the people, the number of people and the height information of the people. Therefore, the edge intelligent control device can judge whether there are people in the area and the specific location of the people, whether the people are moving and the posture of the people based on the status information of these people. For example, it is detected that there are 5 people in area A, of which 2 are in a moving state, 3 are in a sitting state, non-moving state, etc. The heights of the two people in the moving state are 175.8cm and 183.5cm respectively.

[0031] In a specific embodiment, before step S100, the following may also be included: based on the scanning results of each millimeter-wave radar, a virtual model of each area is established, and the millimeter-wave radars, air conditioners, lighting devices and the virtual models of the area located in the area are associated to obtain a relationship chain; and the attribute information of each node on the relationship chain is pre-defined according to the actual use of each area.

[0032] Based on the scanning results of each area in the building space by the millimeter-wave radar, the edge intelligent control device obtains the boundary shape information of each area, the shape and position information of the objects in the area, and establishes a virtual model of each area. This virtual model includes both the model of the building itself and the model of the objects in the area, such as tables, chairs, etc., and stores this virtual model in the edge intelligent control device. With the real-time dynamic detection of each area in the building space by the millimeter-wave radar, when the objects in its scanning range change, such as position movement, type replacement, etc., the edge intelligent control device can receive new object information in a timely manner and update the virtual model in a timely manner. After the virtual model is established, the millimeter-wave radar, air conditioner, lighting device located in the area and the virtual model stored in the edge intelligent control device corresponding to the area are associated to obtain the relationship chain corresponding to the physical device located in the area and the virtual model. The attribute information of each node on the relationship chain is defined in advance according to the actual use of each area. The attribute information includes name information and, for example, if the area is actually an office area, a relationship chain named office area-office area radar-office area model-office area air conditioner-office area lighting device is obtained.

[0033] S200: Send corresponding control instructions to the air conditioner and the lighting device according to a preset strategy based on the relationship between the status information of the person and the first area and the second area.

[0034] According to the relationship between the status information of the personnel and the first area and the second area, the corresponding control instructions are sent to the air conditioner and the lighting device according to the preset strategy. The first area is adjacent to the second area. For example, the first area is an office area, and the second area can be a rest area, a meeting area, or another office area adjacent to the first area. The office area can be an area where office equipment is placed, the rest area can be a tea room, a lunch break room, etc., and the meeting area can be an area for work meetings or discussions. According to the strategy preset in the edge intelligent control device, when the relationship between the status of the personnel and the first area and the second area changes, the millimeter wave radar will convert the scanned personnel status into information data and send it to the edge intelligent control device. The edge intelligent control device integrates the received personnel status information with the virtual model to obtain the relationship between the personnel status in the actual space and the first area and the second area, and according to the strategy, send control instructions to the air conditioner and lighting device on the same relationship chain as the virtual model to achieve precise control of the air conditioner and lighting device.

[0035] In a specific embodiment, refer to Figure 3 , step S200 includes sub-steps S210~S240.

[0036] S210: If it is detected that there are people in the current area, a work instruction is sent to the air conditioner and the lighting device in the current area.

[0037] If it is detected that there are people in the current area, a work instruction is sent to the air conditioner and the lighting device in the current area. The current area includes the first area and the second area. For example, if the millimeter-wave radar detects that there are people in the first area, the personnel status information is sent to the edge intelligent control device, and the edge intelligent control device sends a work instruction to the air conditioner and lighting device in the same relationship chain as the millimeter-wave radar in the first area, so as to control the air conditioner and lighting device in the first area to start working.

[0038] Specifically, the corresponding work instructions can be sent to the air conditioners and lighting devices in the same relationship chain as the virtual model according to the pre-stored mapping relationship table between the virtual model name and the work mode. For example, the first area is the office area, and the second area is the rest area. The pre-stored mapping relationship table includes: office area model-office mode; rest area model-rest mode. The office mode and rest mode store the temperature parameters of the air conditioner and the brightness parameters of the lighting device, wherein the temperature parameters of the rest mode are higher than those of the office mode, and the brightness parameters of the rest mode are lower than those of the office mode.

[0039] In some embodiments, a humidity sensor communicatively connected to the edge intelligent control device may be arranged in the area. The edge intelligent control device may pre-store a humidity range, for example, 40% to 60%. After the air conditioner in the area is turned on, the humidity sensor collects the humidity information in the area in real time and sends it to the edge intelligent control device. The edge intelligent control device compares the real-time received humidity information with the pre-stored humidity range to determine whether the humidity value in the area is within the pre-stored humidity range. If it is not within the pre-stored humidity range, a humidity adjustment control instruction is sent to the air conditioner in the corresponding area to control the temperature rise or fall so as to adjust the humidity in the area and make the people in the area feel more comfortable.

[0040] S220: If it is detected that the last person leaves the first area, obtain a corresponding movement trajectory of the person; the movement trajectory of the person is the movement trajectory of the last person after leaving the first area.

[0041] If the last person is detected to have left the first area, the corresponding person's movement trajectory is obtained; the person's movement trajectory is the movement trajectory of the last person after leaving the first area. For example, the first area is an office area. When the millimeter-wave radar in the first area detects that the last person has left the office area, the millimeter-wave radar in the second area adjacent to the first area obtains the movement trajectory of the last person in the first area after leaving the first area in real time and dynamically. The second area does not refer to a single area, and all areas adjacent to the first area are second areas.

[0042] S230: Determine whether the last person is in the second area according to the movement trajectory of the personnel, and obtain an entry judgment result.

[0043] Whether the last person is in the second area is determined based on the movement trajectory of the person, and an entry judgment result is obtained. Specifically, when the last person is detected to have left the first area, the millimeter-wave radar in the first area sends the height information of the last person to the edge intelligent control device, and the edge intelligent control device promptly obtains the height information of the dynamic people in the second area. If a certain height information of the dynamic people in the second area is the same as the height information of the last person in the first area, it is determined that this person is the last person to leave the first area. The millimeter-wave radar in the second area continues to detect to obtain the movement trajectory of the person. Similarly, the millimeter-wave radars in other areas (i.e., areas not adjacent to the first area) also obtain the movement trajectory of the person in the same way, and then comprehensively judge whether the last person in the first area has entered and is in the second area.

[0044] S240: If the entry judgment result is yes, a continuous operation instruction is sent to the air conditioner and the lighting device in the first area.

[0045] If the entry judgment result is yes, that is, the person's movement track is only in the second area, then it is judged that the last person leaving the area is in the second area. For example, the first area is the office area, and the second area is the tea room in the rest area, or the second area is the office area adjacent to the first area, then it means that the person is very likely to return to the first area within a certain period of time, so a continuous working instruction is sent to the air conditioner and the lighting device in the first area to avoid turning off the air conditioner and the lighting device after the person leaves the first area, and turning on the air conditioner and the lighting device in the first area again when the person returns to the first area from the second area, causing energy waste.

[0046] In a specific embodiment, the method of judging whether the last person is in the second area based on the movement trajectory of the personnel, after obtaining the entry judgment result, further includes the following steps: if the entry judgment result is no, recording the duration of the last person leaving the first area; judging whether the duration of the last person leaving the first area is greater than a first preset value, and obtaining a duration judgment result; if the duration judgment result is no, sending a continuous working instruction to the air conditioner and the lighting device in the first area.

[0047] Specifically, if the entry judgment result is no, that is, the last person in the first area is not in the second area after leaving the first area, the edge intelligent control device records the duration of the last person leaving the first area, and determines whether the duration is greater than a first preset value, for example, the first preset value is 5 minutes. If the duration judgment result is no, that is, the duration is not greater than 5 minutes, a continuous working instruction is sent to the air conditioner and lighting device in the first area to avoid energy waste caused by turning off the air conditioner and lighting device after leaving the first area, and then returning to the first area within a short time and turning them back on. When the person returns to the first area or a new person enters the first area, the recording of the duration is stopped.

[0048] In some embodiments, if the entry judgment result is yes, the step of recording the duration of the last person leaving the first area is also performed. That is, after the last person leaves the first area, if he enters and stays in the second area, the time when the last person left the first area is also recorded to prevent energy waste caused by people staying in the second area for a long time while the air conditioners and lighting devices in the first area continue to work for a long time.

[0049] In a specific embodiment, the first area and the second area are adjacent to each other and there is no partition between them. Temperature sensors communicatively connected to the edge intelligent control device are respectively arranged in the first area and the second area. After judging whether the time when the last person left the first area is greater than a first preset value, the steps are also included: if the duration judgment result is yes, a stop working instruction is sent to the lighting device in the first area; the temperature of the first area and the temperature of the second area are obtained; the temperature difference between the temperature of the first area and the temperature of the second area is calculated, and it is judged whether the absolute value of the temperature difference is greater than the second preset value; if the absolute value of the temperature difference is greater than the second preset value, a continuous working instruction is sent to the air conditioner in the first area.

[0050] Specifically, the first area is adjacent to the second area and there is no partition between them. For example, the first area is an office area, and the second area is another office area adjacent to the first area. If the duration judgment result is yes, that is, it is judged that no personnel have returned to the first area within a certain period of time, the edge intelligent control device sends a stop working instruction to the lighting device in the first area, and the temperature sensors in the first area and the second area send the detected temperature information to the edge intelligent control device, so that the edge intelligent control device can obtain the temperature values ​​of the first area and the second area. The edge intelligent control device calculates the temperature difference between the first area and the second area, and determines whether the absolute value of the temperature difference is greater than the second preset value. At this time, the first area is in an empty state, while the second area is in a occupied state. Since the first area is adjacent to the second area and there is no partition, if the temperature difference between the first area and the second area is greater than the second preset value, the cold air or warm air blown out by the air conditioner in the second area may spread to the first area. In order to ensure that the people in the second area are in a comfortable working environment, it is necessary to increase the power or energy consumption of the air conditioner in the second area. Therefore, after the people in the first area leave, when the temperature difference in the second area is greater than the second preset value, the edge intelligent control device sends a continuous working instruction to the air conditioner in the first area to continue to control the operation of the air conditioner in the first area, thereby reducing the energy consumption of the air conditioners in the first and second areas as a whole.

[0051] After calculating the difference between the temperature of the first area and the temperature of the second area, and determining whether the absolute value of the difference is greater than the second preset value, the method further includes: if the absolute value of the temperature difference is not greater than the second preset value, sending a stop instruction to the air conditioner in the first area. If the temperature difference between the first area and the second area is not greater than the second preset value, there is no need to increase the power or energy consumption of the air conditioner in the second area, and the edge intelligent control device sends a stop instruction to the air conditioner in the first area to control the air conditioner in the first area to stop working, thereby avoiding energy waste caused by the air conditioner in the first area continuing to work.

[0052] In a specific embodiment, refer to Figure 4 If it is detected that there are people in the current area, a work instruction is sent to the air conditioner and the lighting device in the current area, including sub-steps S211~S213.

[0053] S211. If a person is detected to be located in the overlapping area of ​​the first area and the second area, a location distribution map of the person within a preset time period is obtained, wherein the preset time period is a time period before the person is detected to be located in the overlapping area of ​​the first area and the second area.

[0054] In this embodiment, there is an overlapping area between the first area and the second area. If a person is detected to be in the overlapping area between the first area and the second area, that is, the millimeter-wave radars in the first area and the second area detect the status information of the same person, then the edge intelligent control device obtains the position distribution map of the person within a preset time period after receiving the personnel status information sent by the millimeter-wave radars in the first area and the second area, wherein the preset time period is a time period before the person is detected to be in the overlapping area between the first area and the second area. When the edge intelligent control device receives the position information in the personnel status information sent by the millimeter-wave radar, it saves the position information of the person once per unit time, and after a time period, the position information saved per unit time constitutes its position distribution map. The preset time period can be 6 minutes, that is, after the edge intelligent control device receives the personnel status information sent by the millimeter-wave radars in the first area and the second area, it obtains the position distribution map of the person in the first area and the second area within the previous 6 minutes.

[0055] S212: Determine the area sizes of the location distribution map of the first area and the location distribution map of the second area.

[0056] Determine the area size of the location distribution map of the first area and the location distribution map of the second area. Each time the edge intelligent control device saves the location information of a person, it marks a pixel point on the plane map of the corresponding virtual model. Several pixels constitute a location distribution map within a time period. The edge intelligent control device can compare the area size of the location distribution map of the first area and the location distribution map of the second area by comparing the number of pixels.

[0057] S213: Send work instructions to the air conditioners and lighting devices in corresponding areas of the location distribution map with a larger area.

[0058] If the area of ​​the person's position distribution map in the first area is larger than the area of ​​the person's position distribution map in the second area, it is judged that the probability of the person's activity in the first area is greater than the probability in the second area, and the edge intelligent control device sends a work instruction to the air conditioner and lighting device in the first area to control them to start working; otherwise, it sends a work instruction to the air conditioner and lighting device in the second area. This embodiment is suitable for situations where there are fewer people in the building space and they are in overlapping areas. The air conditioner and lighting devices in the corresponding area can be turned on more accurately to avoid unnecessary energy loss caused by turning on the air conditioners and lighting devices in two areas at the same time.

The above-mentioned building energy-saving control method based on edge intelligent control can accurately obtain the status of the personnel through the millimeter-wave radar, and according to the relationship between the real-time status of the personnel and the first area and the second area, more accurately control the operation or shutdown of the air conditioner and lighting devices, avoid energy waste, and achieve energy-saving control.

[0060] An embodiment of the present invention further provides a building energy-saving control device based on edge intelligent control, wherein a building space includes multiple areas, and edge intelligent control equipment is arranged in the building space. The building energy-saving control device based on edge intelligent control can be configured in the edge intelligent control equipment, and each of the areas is provided with a millimeter-wave radar, an air conditioner and a lighting device that are communicatively connected to the edge intelligent control equipment, and the areas include adjacent first areas and second areas.
