Bi-directional wireless intelligent door magnetic detector

Abstract

The invention discloses a bi-directional wireless intelligent door magnetic detector. The bi-directional wireless intelligent door magnetic detector comprises a cylinder and door magnetic switch combination body, a wireless door magnetic sensor and a door magnetic alarm, wherein the wireless door magnetic sensor comprises a door magnetic sensor, door closing and opening circuits, a power module, an MCU (microprogrammed control unit), a voltage-stabilizing and filtering circuit, a Wi-Fi (wireless fidelity) module power supply control circuit, a clock circuit and a low-voltage detection circuit; an input end of the door magnetic sensor is divided into two paths, one path is electrically connected with the door closing circuit and the clock circuit, and the other path is electrically connected with the door opening circuit and the MCU through the voltage-stabilizing and filtering circuit; the voltage-stabilizing and filtering circuit and the MCU form a closed loop through the Wi-Fi module power supply control circuit and a Wi-Fi module; an output end of the door magnetic sensor is electrically connected with the MCU through the door closing circuit and the door opening circuit. The bi-directional wireless intelligent door magnetic detector solves the problems that a detector in the prior art is high in cost, large in size, complicated in circuit and high in power consumption and a battery can only support the detector for a few days, can detect the opening and closing states of doors, windows and drawers, and has the advantages of low power consumption, low cost and small size.

Description

technical field [0001] The invention relates to a door magnetic sensor or detector mainly used in a smart home security system, in particular to a two-way wireless smart door magnetic detector. Background technique [0002] In the smart home access control system, the door magnetic detector is an anti-theft alarm device used to detect whether doors, windows, drawers, etc. The alarm device used by the door switch is the first line of defense for monitoring illegal activities in offices, workplaces, and homes to ensure safety. The usual function of the door magnetic switch is to control whether the door magnet is energized or not, when it is energized, it will be magnetized (close the door), and when it is powered off, it will demagnetize (open the door). Alarm devices can generally be divided into three parts: door magnetic switch, door magnetic sensor or detector, and door magnetic alarm. The door sensor is divided into wired door sensor and wireless door sensor. The wired...
