Wireless door magnetic device with low power consumption and method for controlling wireless door magnetic alarm

Abstract

The invention relates to a wireless door magnetic device with low power consumption. The wireless door magnetic device with the low power consumption comprises a power supply, a main controller, a magnetic reed pipe and a radio frequency emission circuit, wherein the power supply is respectively connected with the main controller and the magnetic reed pipe, the magnetic reed pipe is connected with a signal input end of the main controller, and a signal output end of the main controller is connected with the radio frequency emission circuit. The invention further relates to a method for controlling a wireless door magnetic alarm at low power consumption by employing the device. The method comprises the steps of main control operation processing and interruption control operation processing, wherein in the main control operation processing, the main controller judges whether an alarm signal is received from the magnetic reed pipe, whether an under voltage alarm condition is satisfied and whether a timing heartbeat maintenance condition is achieved; after entering the interruption program operation, the main controller transmits under voltage information, heartbeat information or alarm information by the radio frequency emission circuit so as to achieve wireless interaction with a 3G wireless fixed telephone, thus the wireless door magnetic detection with the low power consumption and the method for controlling the wireless magnetic door alarm can be conveniently applied to an intelligent safety prevention early warning system based on a 3G network.

Description

technical field [0001] The invention relates to the technical field of security products, in particular to the technical field of wireless door magnetic devices, and specifically refers to a low-power wireless door magnetic device and a method for wireless door magnetic alarm control. Background technique [0002] With the popularization of 3G mobile network, a new generation of intelligent security early warning system based on 3G network came into being. In addition to the 3G wireless landline function, the intelligent security warning system based on the 3G network also provides comprehensive security at home in terms of door and window alarms, smoke and gas monitoring, and emergency calls. Usually, the intelligent security early warning system is composed of four parts, one is the probe that senses changes in objects, such as anti-theft door sensor, smoke detector, window infrared sensor, etc.; the other is the terminal 3G wireless landline that realizes interaction; the...

AI Technical Summary

Problems solved by technology

Most of the door magnets on the market before cannot be used in the intelligent security warning system based on 3G network. The reason is that the anti-theft door magnet needs to use a wireless method to realize the interaction with the 3G wireless landline, and it needs to use a specific wireless data communication method.
