specific Embodiment 1

[0079] This embodiment provides a low power consumption target monitoring device. figure 1 is a structural block diagram of a low-power target monitoring device according to an embodiment of the present application. Those skilled in the art can understand that, figure 1 The structure of the low-power target monitoring device shown in the above does not constitute a limitation to the low-power target monitoring device, and may include more or less components than shown in the figure, or combine some components, or arrange different components.

[0080] Combine below figure 1 A specific introduction to each component module of the low-power target monitoring device:

[0081] The infrared sensor 102 is used to monitor the target object within the detection range and send a first monitoring signal;

[0082]The radar sensor 103 is used to monitor the target object within the detection range and send a second monitoring signal. It is worth noting that the infrared sensor 102 moni...

[0091] image 3 It is a structural block diagram of another low-power target monitoring device according to an embodiment of the present application. refer to image 3 , the device of this embodiment at least includes:

[0092] The PIR sensor 202 is used to monitor the target object within the detection range and send out the first monitoring signal. Compared with the traditional active infrared sensor, the PIR sensor 202 does not emit any type of radiation itself, and has good concealment and low device power consumption. Small and cheap;

[0093] The radar sensor 203 is used to monitor the target object within the detection range and send a second monitoring signal, wherein the radar sensor 203 monitors the target object and enters a sleep state after sending the second monitoring signal;

[0094] The latch 204 is electrically connected to the radar sensor 203 and is used to receive the second monitoring signal and record it as high and low level signals. The latch 204 i...

[0102] Based on the low-power consumption target monitoring device in the first specific embodiment, this embodiment also provides a control method of the low-power consumption target monitoring device. Figure 5 is a flow chart of a control method of a low-power target monitoring device according to an embodiment of the present application, such as Figure 5 As shown, the process includes the following steps:

[0103] Infrared sensor monitoring step S301, the infrared sensor monitors the target object and sends out a first monitoring signal. If the controller judges that the target object is detected according to the first monitoring signal or the first level signal, it fails to detect the target object within the first preset time threshold range. If the target object is detected again, enter the radar sensor monitoring step S302, otherwise repeat this step;

[0104] Radar sensor monitoring step S302, the radar sensor monitors and sends a second monitoring signal, if the co...

Abstract

The invention relates to a low-power-consumption target monitoring device, a control method and a low-power-consumption target monitoring system. The monitoring device comprises an infrared sensor used for monitoring a target object and transmitting a first monitoring signal; a radar sensor used for monitoring the target object and sending a second monitoring signal; a latch electrically connected with the infrared sensor and / or the radar sensor, and used for receiving the first monitoring signal and recording the first monitoring signal as a first level signal, and / or receiving the second monitoring signal and recording the second monitoring signal as a second level signal; and a controller used for receiving the first monitoring signal, the second monitoring signal, the first level signal and the second level signal and controlling the working state of the infrared sensor or the radar sensor based on preset control logic according to at least one of the first monitoring signal, the second monitoring signal, the first level signal and the second level signal. According to the application, intermittent monitoring of the infrared sensor and the radar sensor is controlled by applying the latch, so that the standby working time of the system is greatly prolonged.

Description

technical field [0001] The present application relates to the field of smart devices, in particular to a low-power target monitoring device, a control method, and a low-power target monitoring system. Background technique [0002] At present, the design scheme of low-power human presence sensors is usually composed of a mixture of PIR sensor modules and radar sensors. When monitoring stationary human presence scenes, this technical scheme requires the radar sensor and PIR sensor module to work all the way, and consumes a lot of power. [0003] The levels that sensors will touch include motion perception, environmental monitoring, etc. In the application of smart devices, the demand for sensors is higher. For example, the requirements for power consumption are particularly high, so sensors with lower power consumption are especially required. Increase the usage time of the sensor. [0004] At present, no effective solution has been proposed for the problem of high power cons...
