[0016] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0017] Please refer to Figure 1 The present application provides a technical solution: a human body presence sensor, comprising a human body presence detection module, an alarm module, a central control module, a network module, a POE power supply module and a power module, the central control module is connected with the human body presence detection module, the alarm module, the network module, the POE power supply module and the power module respectively, the network module is connected with an external Internet of Things management platform, and the POE power supply module and the power module are respectively used for power supply of the human body presence detection module, the alarm module, the central control module and the network module.

[0018] The human body presence detection module is a radar microwave detector, which is a detector combining microwave receiving and transmitting equipment, and its working principle is based on Doppler effect. The wavelength of microwave is very short, between 1mm and 1000mm, so it is easily reflected by objects. When the microwave signal is reflected by a moving object, the Doppler effect occurs, that is, the frequency of the reflected microwave signal is slightly shifted from the frequency of the transmitted wave signal. At this time, the alarm is considered to be generated, and the signal generated at this time is transmitted to the central control module to trigger the central control module to send an alarm signal to control the alarm module to send an alarm.

[0019] The POE power supply module is connected with the network module, the network module is connected with an external network switch with POE power supply, and the network module is an Ethernet connection unit.

[0020] POE power supply refers to using a conventional Ethernet cable to supply power while transmitting data on the basis of the existing Ethernet CAT-5 wiring infrastructure without any modification, so as to ensure that the cable can provide DC power supply capability for the integrated power supply module of the Ethernet terminal device such as wireless LAN access point AP and other IP-based terminals while transmitting data signals.

[0021] The power supply module is a DC 12V power supply module, which cooperates with the POE power supply module and sets corresponding functions in the central control module, so that the POE power supply and the DC power supply are simultaneously powered, and the DC power supply is preferentially selected.

[0022] The alarm module is a buzzer, which alarms after detecting the alarm signal.

[0023] The central control module is a logic processor, which can receive signals and control the human body presence detection module, the alarm module, the network module, the POE power supply module and the power supply module, so as to realize human body detection, network signal transmission and corresponding alarm functions.

[0024] By the technical scheme, the high-stability radar microwave detector is adopted, the advanced signal analysis and processing technology is adopted, the super-high detection and false alarm prevention performance is achieved, when an intruder passes through the detection area, the detector will automatically detect the activity of the human body in the detection area. If there is dynamic movement, an alarm will be generated, the Ethernet communication network is supported to realize long-distance data acquisition and transmission, the centralized monitoring of human body presence data is realized, the standard POE power supply is supported, the device is powered while transmitting data, and the use is convenient. The utility model has the advantages of scientific design, strong practicability, simple structure and convenient use.
