Abstract

The invention relates to a capacitance human body approach alarming control device. The alarming control device comprises a 220V alternating current power supply, a 12V direct current power supply, a capacitance bridge circuit, a differential pressure signal detecting circuit and a differential pressure signal amplifying and alarming control circuit, wherein the capacitance bridge circuit comprises capacitors C1-C4; the differential pressure signal detecting circuit comprises Schottky diodes D1-D4; certain defects exist in certain finished product monitoring devices or facilities on the market; and the capacitance human body approach alarming control device is designed in order to solve or make up the certain defects existing in various monitoring devices on the market, higher selling prices and other problems. The capacitance human body approach alarming control device is mainly used for detecting whether a human body approaches a fortification area, is flexible and various in the monitoring mode and is not limited by factors such as the size of monitoring areas or properties of articles and the like; when certain cases happen, the alarming device acts dexterously and solves the problems of misinformation of non-substantiality conditions and failed reporting of dangerous warning conditions; four monitoring passageways can be simultaneously used; and a part of monitoring passageways can be used according to the need.

Description

technical field [0001] The invention belongs to the technical field of electronic monitoring, and relates to a capacitive human body approach alarm control device. Background technique [0002] There are many types of monitoring and alarm devices on the market, and the alarms made by infrared sensors as probes (pyroelectric effect devices plus Fresnel lenses) have the largest share. Although the dominant position and active role of this kind of infrared alarm in many fields are unquestionable, they also have some problems in actual use. [0003] The present invention is designed to solve or make up for some defects and relatively high prices of various monitoring devices on the market. [0004] The capacitive human body approach alarm control device described in the present invention has been tested, compared and analyzed in various schemes, and the present invention achieves the expected purpose by only using a small number of commonly used electronic components. The rele...
