Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only 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.
The embodiment of the application provides a radar power control system, which comprises an air conditioner controller, a radar controller and a radar antenna, as shown in fig. 1. After a user starts an air conditioner through remote control or application software, the air conditioner controller controls the radar controller to start, the radar controller controls the radar antenna to start, the radar antenna feeds back detected heartbeats of each object to be detected to the radar controller, the radar controller determines that target objects with at least two heartbeats exist in the objects to be detected, and then the radar antenna is controlled to emit radar waves according to first emission power. The radar antenna sends the sign data of the target object to the air conditioner controller through the radar controller, and the air conditioner controller analyzes the sign data and displays the sign data on the air conditioner panel. The air conditioner controller can be an air conditioner main chip, and the radar controller can be a radar main chip.
The embodiment of the application provides a radar power control method, which can be applied to a radar controller and is used for controlling the power of radar waves emitted by a radar.
The following will describe a detailed description of a method for controlling radar power according to an embodiment of the present application, as shown in fig. 2, and the specific steps are as follows:
step 201: and under the condition that the objects to be detected exist in the detection area of the radar, acquiring the heartbeat quantity of each object to be detected.
In the embodiment of the application, the air conditioner is provided with the radar device and the air conditioner controller, and the radar device is used for detecting data information of an object to be detected in a temperature regulation area of the air conditioner, such as the distance between the object to be detected and the air conditioner, and information such as respiration and heartbeat of the object to be detected. The radar device is provided with a radar controller and a radar antenna, the radar antenna is used for transmitting or receiving radar waves, the radar controller is used for controlling the quantity and the power of the radar antenna which are started, and the radar controller can also be communicated with the air conditioner controller. The air conditioner controller main board controls the speed and the direction of air conditioner blowing and the air conditioner display board displays the data detected by the radar device, so that the functions of wind following people, wind sealing, wind surrounding and the like can be realized in the radar starting process.
After the radar device is started, the radar controller transmits radar waves through the radar antenna, and detects whether an object to be detected exists in a detection area of the radar or not through the radar waves, wherein the transmission power of the radar waves is rated power. If the radar controller determines that the object to be detected exists in the detection area, the radar controller acquires the heartbeat quantity of each object to be detected and is used for determining whether a pregnant woman exists in the object to be detected; and if the radar controller determines that no object to be detected exists in the detection area, indicating that no personnel exist in the detection area, the radar controller reduces the transmitting power.
As an optional implementation manner, before acquiring the number of heartbeats of each object to be detected in the case that the object to be detected exists in the detection area of the radar, the method further includes: under the condition that a radar starting instruction is received, determining whether an object to be detected exists in a detection area; under the condition that no object to be detected exists in the detection area of the radar, determining the transmitting power of the radar as second transmitting power; if the object to be detected exists in the detection area under the second transmission power, changing the second transmission power into rated transmission power; the control radar transmits radar waves according to rated transmission power.
After the radar device is started, if the radar controller determines that no object to be detected exists in the detection area, the rated transmission power of the determined radar is changed into the second transmission power, so that energy consumption is reduced, and the service life of the radar controller is prolonged. The second transmitting power is lower than the rated transmitting power, and the power intensity of the second transmitting power can determine whether an object to be detected exists in the detection area. If the radar controller detects that an object to be detected exists in the detection area under the second transmission power, the radar controller changes the second transmission power into rated transmission power, then the radar is controlled to transmit radar waves according to the rated transmission power, and the heartbeat number of each object to be detected is obtained.
Specifically, a radar antenna is arranged on the radar, and the process of determining that the transmitting power of the radar is the second transmitting power is as follows: when all the radar antennas are started, the radar controller transmits radar waves with rated transmission power, and if the transmission power of the radar is reduced to second transmission power, the number of the current radar antennas is required to be reduced to the number of target antenna radars, wherein the number of the target antenna radars corresponds to the second transmission power.
Illustratively, the radar controller turns on four receive antennas and three transmit antennas when transmitting radar waves at a nominal transmit power, and turns on two receive antennas and one transmit antenna when transmitting radar waves at a second transmit power.
As an alternative implementation manner, under the condition that a radar starting instruction is received, the radar controller determines whether an object to be detected exists in a detection area through the infrared detection device, and under the condition that the object to be detected does not exist in the detection area of the radar, the radar is turned off, namely all radar antennas are turned off, so that energy sources are further saved, and the service life of the radar is prolonged. The infrared detection device can be a device for detecting a human body, such as an infrared sensor.
Step 202: and under the condition that target objects with at least two heartbeats exist in all the objects to be detected, determining the first transmission power according to the distance between the target objects and the radar.
If the radar controller detects that the number of heartbeats of the object to be detected is at least two in all the objects to be detected, the radar controller indicates that at least two hearts exist in the object to be detected, and the object to be detected is considered as a target object of the pregnant woman. Since pregnant women are more vulnerable to the body damage by radar electromagnetic waves than non-pregnant women, the transmission power of the radar controller needs to be reduced, and thus the radar controller changes the rated transmission power to the first transmission power according to the distance between the target object and the radar.
Step 203: in the process that the radar detects the target object by using the radar wave, the radar is controlled to emit the radar wave according to the first emission power.
The radar controller transmits radar waves according to the first transmission power, and detects a target object.
In the application, the radar controller confirms that target objects with at least two heartbeats exist in the object to be detected, and indicates that the target objects are pregnant women, and the radar controller reduces the transmitting power of the radar to the first transmitting power so as to reduce the body damage to the pregnant women and protect the body health of the pregnant women.
As an alternative embodiment, after determining the first transmit power according to the distance between the target object and the radar, the method further comprises: recording a first transmission power; the first transmitting power is used as the initial transmitting power when the radar is started next time; and detecting whether an object to be detected exists in the detection area through the initial transmitting power.
The radar controller controls the radar to emit radar waves according to the first emission power, so that the possibility that pregnant women exist in the detection area when the radar is started next time is high, the radar controller records the first emission power, and when the radar is started next time, the initial emission power of the radar is set to be the first emission power, so that the pregnant women are prevented from being damaged by too high electromagnetic waves. When the radar is started next time, the radar controller detects whether a target object exists in the detection area through the first transmitting power, if the target object exists, the transmitting power is determined again according to the distance between the target object and the radar, so that when the distance between the target distance and the radar is reduced, the transmitting power is further reduced, and the health of the target object is ensured.
As an alternative embodiment, determining the first transmit power according to the distance between the target object and the radar includes: acquiring the distance between a target object and a radar; a first transmit power of the radar is determined based on the distance, wherein the first transmit power is proportional to the distance.
The first transmitting power is proportional to the distance, and the closer the target object is to the radar, the larger the field intensity of the electromagnetic field is, and the more obvious the hazard is, therefore, the radar controller needs to acquire the distance between the target object and the radar, then determine the first transmitting power of the radar according to the distance, and the nearer the target object is to the radar, the transmitting power is reduced, so that the body damage of the radar to the target object is reduced.
Wherein, the formula for calculating the first transmitting power is:
P＝P0(L>L0)；
P＝P1+a(L-L0)(L0>L>L1)；
P＝P2(L<L1)。
wherein, P is power, P0 is rated power, P1 is low power operation power, P2 is power for only reserving ranging, a is a proportionality coefficient, L is distance, and L0 and L1 are preset distances. Wherein L0> L1.
As an optional implementation manner, after acquiring the number of heartbeats of each object to be detected, the method further includes: under the condition that the number of heartbeats of all objects to be detected is one, determining the transmitting power of the radar as rated transmitting power; in the process that the radar detects an object to be detected by using the radar waves, the radar is controlled to emit the radar waves according to rated emission power.
If the radar controller detects that the number of heartbeats of all the objects to be detected is one, the radar controller considers that no pregnant woman exists in the objects to be detected, and in order to improve the detection accuracy, the radar controller determines the transmitting power of the radar to be rated transmitting power, and controls the radar to transmit radar waves according to the rated transmitting power, so that the objects to be detected are detected.
As an optional implementation manner, before acquiring the number of heartbeats of each object to be detected in the case that the object to be detected exists in the detection area of the radar, the method further includes: under the condition that a radar starting instruction is received, determining whether an object to be detected exists in a detection area; under the condition that no object to be detected exists in the detection area of the radar, determining the transmitting power of the radar as second transmitting power; if the object to be detected exists in the detection area under the second transmission power, changing the second transmission power into rated transmission power; the control radar transmits radar waves according to rated transmission power.
After the radar is started, the radar controller obtains a radar starting instruction, and then determines whether an object to be detected exists in a detection area according to rated emission power, if the radar controller determines that the object to be detected does not exist in the detection area of the radar, all the radar antennas are started to waste energy, so that the radar controller changes the rated emission power into second emission power by reducing the number of current radar antennas to the number of target radar antennas, and the number of target radar antennas corresponds to the second emission power.
And the radar controller determines whether an object to be detected exists in the detection area under the second transmitting power, if the radar controller determines that the object to be detected exists in the detection area, the second transmitting power is changed into rated transmitting power, the radar is controlled to transmit radar waves according to the rated transmitting power, and the detection accuracy is improved.
As an alternative embodiment, after controlling the radar to emit radar waves, the method further comprises: acquiring physical sign data of a detected object; and sending the sign data to an air conditioner controller so that the air conditioner controller can display analysis results after analyzing the sign data.
After the radar controller controls the radar to emit radar waves, the sign data of the detected object are obtained, then the sign data are sent to the air conditioner controller, the air conditioner controller analyzes the sign data, and the analysis result and the sign data are displayed on the air conditioner panel, so that the user can see the sign data conveniently. Wherein the physical sign data comprise the height, the body type, the breathing frequency, the heartbeat frequency and the like of the detected object, and the analysis result comprises diet advice, exercise advice and the like.
Optionally, the embodiment of the application further provides a processing flow chart of a radar power control method, as shown in fig. 3, and the specific steps are as follows.
Step 301: if the object to be detected is not present in the detection area, step 302 is executed, and if the object to be detected is present, step 303 is executed.
Step 302: and determining the transmitting power of the radar as the second transmitting power, or turning off the radar.
Step 303: judging whether target objects with at least two heartbeats exist in all the objects to be detected, if so, executing step 304, and if not, executing step 305.
Step 304: a first transmit power is determined based on a distance between the target object and the radar.
Step 305: and determining the transmitting power as the rated transmitting power.
Step 306: and sending the physical sign data to an air conditioner controller, and displaying an analysis result by an air conditioner panel.
Step 307: it is determined whether a radar shutdown instruction is received, if so, step 308 is executed, and if not, step 301 is returned.
Step 308: the radar is turned off.
According to the application, under the condition that an object to be detected exists in a detection area, the position information and the sign information of the object to be detected are detected through rated power, so that the detection accuracy is improved, the open radar antenna is reduced or closed under the condition that the object to be detected does not exist, the energy loss is reduced, and the emission power is reduced under the condition that a target object such as a pregnant woman is detected, so that the health of the pregnant woman is protected.
