Abstract

The invention provides a passive position detecting device. The device comprises a position switch, a controller, a modulation circuit, an antenna, a rectifying circuit and a voltage stabilizing circuit. The antenna is connected to the voltage stabilizing circuit through the rectifying circuit. The voltage stabilizing circuit is used to output a direct voltage as the work power supply of the controller and the position switch. The position switch is connected to the controller and is used for detecting whether a detected object is in place and generating position information. The controller isconnected to the antenna through the modulation circuit and is used for acquiring the position information, generating positioning information according to the position information, sending the information to the modulation circuit to carry out modulation, and then sending to a reader through the antenna. By using the passive position detecting device, the power supply can be provided for the position switch through wireless power taking and the wireless transmission of data can be realized so that the workload and the cost of the laying of a power line and a data line are avoided.

Description

technical field [0001] The invention belongs to the technical field of position detection, and more specifically relates to a passive position detection device. Background technique [0002] In the automatic control system, it is an important part to detect the position of the moving object. At present, devices such as infrared sensors or laser displacement sensors are usually used in methods for detecting the position of moving objects, but there are problems of high cost and heavy workload of power-taking and wiring. Contents of the invention [0003] The object of the present invention is to provide a passive position detection device, aiming to solve the problems of high cost and heavy workload of power-taking and wiring in the prior art of active position detection devices such as infrared sensors or laser displacement sensors. [0004] In order to achieve the above purpose, an embodiment of the present invention provides a passive position detection device, includin...
