Abstract

The invention discloses a self-powered wireless two-way communication sensor which comprises a microcontroller unit 9, a power supply management control unit 7 connected with the microcontroller unit 9, and a wireless signal transceiving unit 11 connected with the microcontroller unit 9, as well as soft magnet 1, a conductive coil 2, a permanent magnet 3 and a reset spring 4, wherein the wireless signal transceiving unit 11 can realize two-way communication and one-way receiving or transmitting; the positions of the conductive coil 2, the permanent magnet 3 and the reset spring 4 are fixed relatively; the conductive coil 2 is sheathed on the soft magnet 1, the fulcrum of the soft magnet 1 in the conductive coil 2 is fixed relative to the conductive coil 2, two ends of the soft magnet 1 can do certain vertical displacement around the fulcrum, and the displacement can not exceed the height of inside space at two ends of the permanent magnet 3; one end of the soft magnet 1 is connected with the reset spring 4; and the soft magnet, the coil 2, the permanent magnet 3 and the reset spring 4 forms a self-powered energy collection unit 20. According to the invention, no wiring, batteries or maintenance is required, and microniaturization can be achieved.

Description

technical field [0001] The invention belongs to the application technical fields of wireless sensor network, intelligent building, intelligent home and the like, and is suitable for wireless sensors and control switches. Background technique [0002] With the development of industrial control and sensing technology, various sensor and control switch applications are becoming more and more common. Traditional sensor and switch products require signal lines for signal transmission and / or power lines for power to function properly. However, in many practical applications, due to environmental constraints, wiring is basically impossible or very expensive. At this time, wireless sensing and control technology becomes an ideal choice. However, wireless technology only solves the problem of not needing signal lines, but it also requires energy. Therefore, batteries are often used to power wireless sensors and switches in places where power lines cannot be laid. The service life o...
