[0012] When the controller of the present invention determines that the time length since the last time a personnel location scanning request was sent to the personnel location scanning device is greater than a preset time length threshold, it sends a personnel location scanning request to the personnel location scanning device again to prevent the personnel's position from changing or leaving during operation, thereby achieving real-time adjustment based on the dynamic changes of the personnel and realizing intelligent control of the cooling fan.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] According to an embodiment of the present invention, a fan rotation angle control embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] An embodiment of the present invention provides a fan, such as Figure 1 As shown, the fan includes a personnel position scanning device 1, a controller 2 and an oscillating motor 3 in the fan, wherein the controller 2 in the fan sends a personnel position scanning request to the personnel position scanning device 1 of the fan; the personnel position scanning device 1 responds to the personnel position scanning request sent by the controller 2 of the fan and performs scanning within a preset angle range; if the personnel position scanning device 1 detects the presence of a person at a target angle, it generates target angle information and sends it to the controller 2; the controller 2 receives the target angle information sent by the personnel position scanning device 1, and controls the oscillating motor 3 in the fan to oscillate the fan to the target angle to supply air.

[0033] The controller 2 of the embodiment of the present invention is connected to the personnel position scanning device 1, wherein the personnel position scanning device 1 is not limited and can be an infrared sensor or other sensors. Specifically, taking the photoelectric proximity sensor as an example, the photoelectric proximity sensor can determine the proximity state of the object by measuring the intensity of the reflected light or detecting whether the light beam is blocked, and is used to detect the position of the object, etc. Its structure is relatively simple and the cost is low. Compared with the infrared sensor, its accuracy is higher when high-precision measurement or long-distance measurement is required. This is just an example; the fan is turned on, the whole machine starts working, and the left and right shaking function is turned on. The controller 2 in the fan can send a personnel position scanning request to the personnel position scanning device 1. The personnel position scanning device 1 responds to the personnel position scanning request sent by the controller 2 and can scan within a preset angle range. The preset angle range is not limited, as long as it is not greater than the shaking angle range of the electric fan, such as Figure 2 As shown, the fan moves in a clockwise direction with a range of 360°. The corresponding photoelectric sensor can also scan the position of personnel in a range of 360°, which is just an example.

[0034] When the personnel position scanning device 1 detects the presence of a person at the target angle, it can generate target angle information and send it to the controller 2. There is no limitation on the method of generating the target angle information after the presence of a person is detected at the target angle. The personnel position scanning device 1 can record the current angle after detecting the presence of a person at the current angle, and then generate target angle information for all scanned angles and send it to the controller 2 after completing the scanning within the preset angle range. Alternatively, the personnel position scanning device 1 can directly generate target angle information and send it to the controller 2 after detecting the presence of a person at the current angle during the scanning process. After receiving the target angle information, the controller 2 can directly control the shaking motor 3 to shake the fan to the target angle. After receiving the next target angle information, the controller controls the fan to shake left and right to cover all the received target angle information. Alternatively, after receiving the target angle information, the target angle air supply may not be performed first. After determining that the personnel position scanning device 1 has completed the scanning within the preset angle range, the controller 2 counts all angle information sent by the personnel position scanning device 1, and then controls the shaking motor 3 to shake left and right to cover all angles. This is just an example.

[0035] Among them, the method for the controller 2 to determine whether the personnel position scanning device 1 has completed the scan within the preset angle range is not limited. The time required for the personnel position scanning device 1 to complete the preset angle range may be pre-recorded. After sending a personnel position scanning request to the personnel position scanning device 1, the timing is started until the recorded time reaches the time required for the personnel position scanning device 1 to complete the preset angle range, and it is determined that the personnel position scanning device 1 has completed the scan within the preset angle range. It is also possible to determine whether the target angle in the target angle information sent by the personnel position scanning device 1 is the last angle in the fixed scanning path of the personnel position scanning device 1. If it is the last angle, it can be determined that the personnel position scanning device 1 has completed the scan within the preset angle range. This is just an example.

[0036] After the controller 2 receives the target angle information sent by the personnel position scanning device 1, it can control the shaking motor 3 in the fan to shake the fan to the target angle to supply air. The personnel position scanning device 1, that is, the photoelectric proximity sensor, can output a high level or low level signal to the controller 2 after detecting the presence of a person at the target angle. After receiving the signal, the controller 2 can convert the signal fed back by the photoelectric proximity sensor into a specific output angle through the built-in algorithm processing. Based on the specific output angle, the controller 2 controls the shaking motor 3 to shake the fan to a specific angle to supply air.

[0037] The fan provided by the present invention has a controller in the fan that sends a personnel position scanning request to a personnel position scanning device of the fan. The personnel position scanning device performs a scan within a preset angle range based on the personnel position scanning request sent by the controller, and if a person is detected at a target angle, generates target angle information and sends it to the controller. The controller receives the target angle information sent by the personnel position scanning device, controls the shaking motor in the fan to shake the fan to the target angle to supply air. Through the coordinated work of the personnel position scanning device and the controller, the shaking angle can be adjusted according to the actual position of the person, thereby ensuring the efficient operation of the fan and providing the user with a more comfortable and convenient use experience.

[0038] Specifically, the fan is a cooling fan, such as Figure 3 As shown, the base of the cooling fan includes a water tank for humidification and a submersible pump for supplying water to the wet curtain. The fuselage support rod contains a water pipe. The photoelectric proximity sensor is installed on the head support structure rod. It can scan personnel according to the shaking range of the fan. The head part of the cooling fan can not only shake 360° left and right, but also shake 90° up and down. This is just an example.

[0039] Specifically, the target angle includes at least one angle. After the controller 2 receives the target angle information sent by the personnel position scanning device 1, it determines whether the target angle in the target angle information is one or more; if the target angle in the target angle information is one, the shaking motor 3 is controlled to shake the fan to the target angle to supply air.

[0040] After receiving the target angle information sent by the personnel position scanning device 1, the controller 2 of the embodiment of the present invention can determine whether the target angle in the target angle information is one or more. If the target angle in the target angle information is one, the shaking motor 3 can be controlled to shake the fan to the target angle, and can stop at the target angle to supply air.

[0041] If the controller of the present invention determines that the target angle is one, it can directly control the shaking motor to make the fan shake to the target angle to supply air, so that the fan shakes to the position where the personnel are located, thereby increasing the proportion of time that the personnel are blown by the wind and the utilization rate of the fan.

[0042] In an optional implementation, if there are multiple target angles in the target angle information, the controller 2 selects the maximum angle value and the minimum angle value among the multiple target angles to determine the target angle range; and controls the shaking motor 3 to make the fan shake left and right based on the target angle range.

[0043] If the controller 2 of the embodiment of the present invention determines that there are multiple target angles in the target angle information, the maximum angle value and the minimum angle value among the multiple target angles can be selected to determine the target angle range. For example, if the target angles include 10°, 20°, -50°, and -10°, the maximum angle value of 20° and the minimum angle value of -50° can be selected to determine the target angle range as [-50°, 20°]. The controller 2 then controls the shaking motor 3 based on the target angle range to make the fan shake left and right within the target angle range, thereby ensuring that the wind can accurately cover the area where people are located. This is just an example.

[0044] In an optional embodiment, before sending a personnel location scanning request to the personnel location scanning device 1, the controller 2 responds to the fan power-on command, executes the step of sending a personnel location scanning request to the personnel location scanning device 1, and / or determines whether the time since the last time the personnel location scanning request was sent to the personnel location scanning device 1 is greater than a preset time threshold. If the time since the last time the personnel location scanning request was sent to the personnel location scanning device 1 is greater than the preset time threshold, the step of sending a personnel location scanning request to the personnel location scanning device 1 is executed.

[0045] The embodiment of the present invention does not limit the timing when the controller 2 sends a personnel position scanning request to the personnel position scanning device 1. After responding to the fan power-on instruction, the controller 2 can send a personnel position scanning request to the personnel position scanning device 1, perform the first personnel position scan after this power-on, and control the fan to shake its head to the target angle for air supply. In order to provide a more comfortable and humane experience, a timing detection mechanism can also be designed. The controller 2 can determine whether the time since the last time the personnel position scanning request was sent to the personnel position scanning device 1 is greater than the preset time threshold. If the time since the last time the personnel position scanning request was sent to the personnel position scanning device 1 is greater than the preset time threshold, the personnel position scanning request can be sent to the personnel position scanning device 1 again. For example, after the fan supplies air at the last target angle for 5 minutes, the controller 2 will control the personnel position scanning device 1 to perform scanning detection within the preset angle range again. After the personnel position scanning device 1 scans the personnel at the target angle this time, the target angle information can be sent to the controller 2. The controller 2 can again control the shaking motor 3 to shake the fan to the target angle for air supply based on the target angle determined by the re-scanning. This is just an example.

[0046] When the controller of the present invention determines that the time length since the last time a personnel location scanning request was sent to the personnel location scanning device is greater than a preset time length threshold, it sends a personnel location scanning request to the personnel location scanning device again to prevent the personnel's position from changing or leaving during operation, thereby achieving real-time adjustment based on the dynamic changes of the personnel and realizing intelligent control of the cooling fan.

[0047] In an optional embodiment, after the controller 2 sends a personnel location scanning request to the personnel location scanning device 1, if the target angle information sent by the personnel location scanning device 1 is not received within a preset time period, or if the target angle information sent by the personnel location scanning device 1 includes information indicating that no person is detected, the controller 2 controls the shaking motor 3 to turn off the shaking function, or turns off the fan.

[0048] After the personnel position scanning device 1 of the embodiment of the present invention completes the personnel position scanning within the preset angle range, if no personnel is detected, there is no need to send the target angle information to the controller 2. Correspondingly, if the controller 2 does not receive the target angle information sent by the personnel position scanning device 1 within the preset time period, it can be determined that there is no one in the area, and the shaking head motor 3 can be controlled to turn off the shaking head function, or turn off the fan, wherein the preset time period can be set according to the duration of the personnel position scanning device 1 to complete the personnel position scanning within the preset angle range; if the personnel position scanning device 1 completes the personnel position scanning within the preset angle range and no personnel is detected, it can also send information to the controller 2 to prompt that no personnel is detected. After the controller 2 determines that there is no one in the area, it can control the shaking head motor 3 to turn off the shaking head function, or even turn off the fan.

[0049] After the controller of the embodiment of the present invention turns off the fan, it needs to be manually restarted. After the restart, the whole machine starts to work, and the controller sends a personnel position scanning request to the personnel position scanning device.

[0050] The embodiment of the present invention also provides a method for controlling the rotation angle of a fan, which is applied to Figure 1 The personnel position scanning device 1, the controller 2 and the shaking motor 3 shown in the figure, wherein Figure 4 As shown, the personnel position scanning device 1 is used to execute step S101 to step S102, and the controller 2 is used to execute step S201 to step S202.

[0051] Step S201: sending a personnel location scanning request to a personnel location scanning device of a fan.

[0052] Step S101 , in response to a personnel position scanning request sent by a controller of a fan, scanning is performed within a preset angle range.

[0053] Step S102: If the presence of a person is detected at the target angle, target angle information is generated and sent to the controller.

[0054] Step S202, receiving the target angle information sent by the personnel position scanning device, and controlling the shaking motor in the fan to shake the fan to the target angle to supply air.

[0055] In the embodiment of the present invention, the fan is turned on, the whole machine starts working, and the left and right shaking function is turned on. The controller in the fan can send a personnel position scanning request to the personnel position scanning device. The personnel position scanning device responds to the personnel position scanning request sent by the controller and can perform a scan within a preset angle range. When the personnel position scanning device detects the presence of a person at the target angle, it can generate target angle information and send it to the controller. After receiving the target angle information sent by the personnel position scanning device, the controller can control the shaking motor in the fan to shake the fan to the target angle to supply air.

[0057] In a specific embodiment, Figure 5 As shown, the fan starts to work, and after the shaking function is turned on, the controller sends a personnel position scanning request to the photoelectric proximity sensor. The photoelectric proximity sensor scans a circle according to the preset angle range to see if a person is detected. If no person is detected, the controller can turn off the fan. If a person is detected, the target angle information including the signal output angle is sent to the controller. The controller shakes left and right according to the target angle information fed back by the photoelectric proximity sensor, and the controller can determine whether the time since the last time the personnel position scanning request was sent to the personnel position scanning device is greater than the preset time threshold. If the time since the last time the personnel position scanning request was sent to the personnel position scanning device is greater than the preset time threshold, the photoelectric proximity sensor can be repeated to send the personnel position scanning request.
