Maintenance-free wireless door sensor and wireless door sensor system

Abstract

The invention relates to a maintenance-free wireless door sensor and a wireless door sensor system. The door sensor comprises a door sensor body and a door sensor pedestal; the door sensor body is fixed on the door sensor pedestal; and the door sensor body comprises a casing, a chargeable battery, a solar cell panel, a wireless energy collecting and converting device, a USB charging interface and a mini coil, wherein the solar cell panel is arranged on the casing, the wireless energy collecting and converting device is arranged in the casing, the USB charging interface is arranged at one side of the casing, and the mini coil is arranged in the casing. The maintenance-free wireless door sensor of the structure can ensure that the door sensor does not require maintenance in the service life and realize maintenance-free automatic power supply, and is simple in structure and wide in application range.

Description

technical field [0001] The present invention relates to the mechanical field, in particular to security, and specifically refers to a maintenance-free wireless door magnetism and a wireless door magnetism system. Background technique [0002] Wireless door magnetism has been widely used in the security alarm industry. Its basic working principle is to control the switch state of the reed switch in the door magnetism through the distance between the magnet and the door magnet (magnetic induction function component). When the switch state of the reed switch changes, the wireless transmission function part in the wireless door sensor sends the 24-bit address code of the door sensor to the host, and the alarm host performs corresponding process processing after receiving the signal. [0003] However, the current domestic wireless door magnetic products have some inherent defects, which have not been fundamentally resolved, resulting in poor practicability, narrow application ran...

AI Technical Summary

Problems solved by technology

[0004] 1. There are defects in the installation method: due to the defects in the ordinary door magnetic design, there are big problems in the installation

"The installation is difficult and the installation efficiency is low" is an important obstacle restricting the large-scale promotion and use of Yuanxian door magnetism

[0006] 2. Installation and use will damage the home decoration: due to the defects of ordinary door magnetic design, if you use screws to install wooden doors, it will inevitably cause certain damage to the door and door frame; and the door frame caused serious damage

[0007] 3. The battery of the door sensor in the prior art is troublesome to replace, which is not conducive to the long-term use of the door sensor

[0008] Due to the above defects in the installation of ordinary wire door magnets, the installation is too complicated, and the installation damages the interior decoration, which limits the large-scale promotion and use of civilian anti-theft alarms.
