Based on the control system of the air exhausting equipment described above, as shown in fig. 4, the present embodiment further provides a control method of the air exhausting equipment, which includes steps S100 to S600.
Step S100) a user sets the infrared thermopile sensor to the top or the side of the air supply space. The infrared thermopile sensor 120 is used to collect temperature values of each region. In the bathroom scenario of the present embodiment, the infrared thermopile sensor 120 is disposed at the top of the air supply space. In the present embodiment, in the vehicle air conditioning scenario, the infrared thermopile sensor 120 is provided to the side of the air supply space so that the user can be detected by the infrared thermopile sensor. In the present embodiment, the infrared thermopile sensor 120 is disposed on the exhaust device 130, so that the infrared thermopile sensor 120 can better receive temperature data.
Step S200) the data processing unit divides an air supply space into a plurality of areas. In the present embodiment, the data processing unit 110 divides the air supply space into 4 × 4 matrix spaces or square matrix spaces so that the air-discharging device 130 can supply air to each area within each matrix area with precision.
Step S300) the user stores the area number of each area, the wind direction data corresponding to the area number and the wind speed data corresponding to the area number into the instruction database. In this embodiment, the instruction database 140 stores the wind direction and wind speed data of each area, so that the subsequent data processing unit 110 can issue an accurate instruction to the exhaust device 130. Optionally, in order to facilitate user operation, a manufacturer of the exhaust device directly sets standard data of wind direction and wind speed of each area, and stores the standard data in the instruction database. For example, the wind speed corresponding to the region with the region number 1 in the command database 140 is 2.75 m/s, and the wind direction corresponding thereto is 90 degrees.
Step S400) the data processing unit determines whether a user exists in each area of the air supply space. If the data processing unit 110 determines that there is a user, step S500 is executed, and if the data processing unit 110 determines that there is no user, the step is executed in a loop. In this embodiment, the data processing unit 110 determines whether the user is present through the infrared thermopile sensor 120, and in other embodiments, the data processing unit 110 may also determine whether the user is present in the air supply space through the depth sensor.
Step S500) the data processing unit sends a control instruction to the air exhaust equipment according to the area where the user is located. The control instructions comprise a first control instruction for controlling the wind speed of the air exhaust device and a second control instruction for controlling the wind direction of the air exhaust device.
Step S600) the air exhausting device 130 adjusts the wind speed according to the first control instruction, and adjusts the wind direction according to the second control instruction. Since the parameters of the first control command and the second control command are retrieved by the data processing unit 110 through the command database 140, the wind speed and the wind direction adjusted by the data processing unit 110 can make the user feel comfortable.
The steps S100 to S300 are pre-setting steps, so that the steps S100 to S300 do not need to be repeated before using the control method each time on the premise of no other requirements after the user setting is completed.
As shown in fig. 5, step S400) the data processing unit determines whether there is a user in each area of the air supply space, and specifically includes steps S410-S430.
Step S410) the data processing unit obtains the temperature variation of each area in real time, as shown in fig. 6, specifically including steps S411 to S413. Step S411) the data processing unit collects real-time temperature values of each area in real time. Step S412) the data processing unit compares the real-time temperature values of each area, and finds out the lowest temperature value as the environmental temperature value of the air supply space. The data processing unit obtains the ambient temperature value in this step, so as to facilitate the subsequent judgment of whether the user exists in the area. Step S413) the data processing unit calculates the amount of temperature change for each area. The temperature variation is the difference between the real-time temperature value and the environmental temperature value of the area. The greater the difference between the real-time temperature value and the ambient temperature value for an area, the greater the likelihood that a user will be in the area.
Step S420) the data processing unit determines whether the temperature variation of each region is greater than a predetermined threshold. If yes, the data processing unit 110 executes step S430, otherwise, returns to step S410) the data processing unit obtains the temperature variation of each area in real time. In the present embodiment, the data processing unit 110 needs to compare the temperature variation of each region. Preferably, the developer may perform model training on the temperature variation of each area when the user uses the exhaust device 130 each time through a machine learning algorithm, so that the obtained model may obtain the preset threshold. Alternatively, the developer stores the preset threshold directly in the data processing unit 110 in order to reduce the amount of calculation of the data processing unit 110. The preset threshold obtained by machine learning is more accurate, so that the data processing unit 110 can more accurately find the position of the user. For example: the data processing unit 110 obtains that the preset threshold is 20 degrees centigrade through a machine learning model, the environment temperature of each region of the air supply space is 10 degrees centigrade at this time, and when the temperature variation obtained by subtracting 10 degrees centigrade from the real-time temperature value of a certain region in the air supply space is greater than 20 degrees centigrade, the data processing unit 110 determines that the region is occupied.
Step S430) the data processing unit determines that the user exists in the area. After the data processing unit 110 determines that the user exists in the area, the data processing unit 110 may perform step S500) the data processing unit sends a control command to the air exhausting device according to the area where the user is located. The wind speed of the air-discharging device 130 is determined by the distance between the user and the air-discharging device 130, i.e. the farther the user is from the air-discharging device 130 in the air supply space, the faster the wind speed of the air-discharging device 130, so as to ensure that the user can get the most comfortable hot wind or cold wind. The direction of the air-discharging device 130 is determined by the relative position relationship between the user and the air-discharging device 130, that is, the hot air or the cold air blown by the air-discharging device 130 is on the straight line where the air-discharging device and the user are located, so that the user can feel the flow of the hot air or the cold air.
As shown in fig. 7, step S500) the data processing unit transmits a control command to the exhaust device according to the area where the user is located includes steps S510-S530.
Step 510) the data processing unit calls wind speed data corresponding to the area number from the instruction database according to the area number of the area where the user is located. Since the area number is already set by the command database, the data processing unit 110 can accurately set the specific parameters.
Step S520) the data processing unit generates a first control instruction according to the wind speed data.
Step S530) the data processing unit sends a first control instruction to the exhaust device.
As shown in fig. 8, step S500) the data processing unit sends a control command to the exhaust device according to the area where the user is located includes steps S540-S560.
Step 540) the data processing unit calls the wind direction data corresponding to the area number from the instruction database according to the area number of the area where the user is located. Since the area number is already set by the command database, the data processing unit 110 can accurately set the specific parameters.
Step 550) the data processing unit generates a second control instruction according to the wind direction data.
Step S560) the data processing unit sends a second control instruction to the exhaust device.
In this embodiment, there is no correlation between steps S510-S530 and steps S540-S560, and they can be executed separately, and the data processing unit first calls who has no influence on the final control result.
The rotation speed of the fan 132 is determined by the distance between the user and the air exhausting device 130, i.e. the farther the user is away from the air exhausting device 130 in the air supply space, the faster the rotation speed of the fan 132 is, so as to ensure that the user can obtain the most comfortable hot or cold air. The angle of the rotating means is determined by the relative position relationship between the user and the air discharging device 130, that is, the hot air or cold air blown by the air discharging device 130 through the rotating means is on the straight line where the air discharging device 130 and the user are located, so that the user can feel the flow of the hot air or cold air. For example: when the user enters the air supply space for the first time, the infrared thermopile sensor 120 detects that the temperature variation of an area is greater than the preset threshold, that is, the data processing unit 110 determines that the area is occupied. After determining that there is a person in the area, the data processing unit 110 adjusts the rotation speed and the angle of the fan 132 to the rotation speed and the angle corresponding to the area in the instruction database 140 through the instruction database 140. When the user leaves the air supply space, the infrared thermopile sensor 120 detects that the temperature variation of an area is smaller than the preset closing threshold, the data processing unit 110 determines that the user leaves the air supply space, and the data processing unit 110 powers off the exhaust device 130. For example: the preset closing threshold is set to 5 degrees celsius, and when the temperature variation of each zone is less than 5 degrees celsius, the data processing unit 110 powers off the air exhausting device 130. The problem of resource waste caused by the fact that a user forgets to power off can be solved by setting the preset closing threshold.
The data processing unit realizes the regulation and control of each parameter of the air exhaust equipment by sending the first control instruction and the second control instruction. Optionally, the control instructions include third control instructions, which may control the lighting of the air exhaust device 130. For example, the light fixture darkens when the user is near the exhaust device 130 and brightens when the user is away from the exhaust device.
Optionally, when the area where the user is located is more than two areas that are not adjacent to each other, that is, the data processing unit 110 considers that there are multiple users in the air supply space, the multiple rotating devices drive the multiple air outlets to rotate to different areas to supply air to the multiple users.
Optionally, when the area where the user is located is more than two adjacent areas, that is, the data processing unit 110 considers that there is one user in the air supply space or that the multiple users are close to each other, the wind speed data in the first control instruction is an average value of wind speed data corresponding to the multiple areas where the user is located, and the wind direction data in the second control instruction is an average value of wind direction data corresponding to the multiple areas where the user is located.
The control method provided in this embodiment adopts a scheme of monitoring temperature variation at different positions of an air supply space, determines a real-time position of a user in the space, and adjusts an operation state of an air exhaust device according to the real-time position, such as adjusting a wind speed or a wind direction of an air outlet. When the user moves the position in the air supply space, the control method can adjust the wind direction and the wind speed of the air outlet in time, so that the wind discharged from the air outlet can face the user, and the user can obtain better user experience. According to the control method, the wind direction and the wind speed of the air outlet do not need to be manually adjusted by a user, so that the user operation is reduced, the electric shock of the user is effectively prevented, and the safety risk is reduced.
