Abstract

A human proximity sensing alarm based on the Internet of Things relates to an Internet of Things control technology, in order to solve the problem that the existing proximity sensing alarm with self-locking function cannot be remotely closed. The siren body of the present invention is used to send out the alarm sound and strong light; the wifi module of the Internet of Things includes a remote control unit and a relay K; the common end of the relay K switch is connected with the fire wire of the 220V AC power supply, and the normally open contact of the relay K switch It is connected to the positive input terminal of the power supply of the alarm body, and the negative input terminal of the power supply of the alarm body is connected to the neutral line of the 220V AC power supply. The induction circuit is used to drive the relay K switch from a normally closed contact to a Normally open contact; the remote control unit is used to convert the switch of the drive relay K from a normally open contact to a normally closed contact after receiving a shutdown command from the communication device. The beneficial effect is that the self-locking and remote closing functions of the alarm are realized.

Description

technical field [0001] The invention relates to an Internet of things control technology. Background technique [0002] Proximity sensing siren is one of the common sirens. It is often used for safety alarms in dangerous goods, safes, and isolation areas. When the proximity sensing siren is triggered, it will emit a high-decibel sound alarm and a strong light to scare away The role of thieves or reminders; the existing proximity sensor siren, when the trigger stops, the siren is automatically closed, and the effect of warning or anti-theft is not good; in order to improve the effect of warning or anti-theft, the existing siren is added Self-locking circuit, after the alarm is triggered, the alarm will continue to open, and finally the alarm will be turned off manually, but the remote shutdown of the proximity sensor alarm with self-locking function cannot be realized. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the ...
