Mobile induction wireless alarm device and system

Abstract

The invention provides a mobile induction wireless alarm device and system, and the device comprises a microwave induction circuit module, an LED lamp / buzzer control circuit module, a wireless transmission circuit module, an MCU main control module, and a USB power supply circuit module which is used for supplying power to the MCU main control module. The microwave induction circuit module is usedfor converting changes of reflected waves generated by detecting object movement into electric signals to be output according to the Doppler principle. The MCU main control module performs AD conversion on the electric signals into digital signals for logic processing to obtain an MCU processing result; the wireless transmission line module is used for wirelessly transmitting the MCU processing result; and the LED lamp / buzzer control circuit module is used for giving a light alarm / sound alarm according to the MCU processing result. The advantage of the invention is that the more precise detection and alarm of a moving object can be achieved.

Description

technical field [0001] The invention relates to an alarm device and system, in particular to a mobile induction wireless alarm device and system. Background technique [0002] At present, to detect human motion, most products use infrared sensing technology to determine whether someone is moving by detecting the infrared signal emitted by the human body. At present, most of the alarm equipment adopts the device to actively use the buzzer to alarm, the indicator light flashes, connect to bluetooth or wifi, upload to the cloud, and view the alarm information through the mobile APP. [0003] Infrared sensing technology is a passive sensing technology. It detects whether someone is moving by detecting the infrared signal emitted by the human body. This technology is susceptible to external environment interference. For example, when the ambient temperature is close to the human body temperature, it is easy to cause induction failure and poor penetration. Easily blocked by obsta...

AI Technical Summary

Problems solved by technology

[0003] Infrared sensing technology is a passive sensing technology. It detects whether someone is moving by detecting the infrared signal emitted by the human body. This technology is susceptible to external environment interference. For example, when the ambient temperature is close to the human body temperature, it is easy to cause induction failure and poor penetration. Easily blocked by obstacles, etc.

Buzzer alarms, flashing lights, etc., are likely to cause troubles for sensitive groups such as infants and the elderly, and may not be able to reach the owner in time.

Bluetooth connects to the mobile phone, and Wifi connects to upload to the cloud. The owner needs to actively check the alarm information of the mobile phone, and it is easy to miss the information.
