Infrared video monitoring system

Abstract

The invention discloses an infrared video monitoring system, which comprises an infrared receiving circuit, a single-chip microcomputer, a reset circuit, an amplifying circuit and a communication circuit, wherein the single-chip microcomputer is respectively connected to the amplifying circuit, the infrared receiving circuit and the communication circuit; the amplifying circuit is also connected to an LED dynamic display circuit; the communication circuit is also respectively connected to N decoding circuits; and output ends of the N decoding circuits are all connected to image acquisition equipment. According to the infrared video monitoring system, through using an operational amplifier U2, a chip U1 and a chip U3, a received infrared signal can be accurately fed back to a chip U4 to output, so that the sensitivity and the receiving range of an infrared receiver are improved, and furthermore, the circuit structure is simple, so that the manufacturing cost and the manufacturing difficulty are reduced, and the infrared video monitoring system is suitable for promotion and application.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an infrared video monitoring system. Background technique [0002] Coal mines and other operating environments are harsh and accidents are prone to occur. Using the video surveillance system, ground monitoring personnel can directly and real-time monitor the underground situation, not only can intuitively monitor and record the safety production situation of the underground work site, but also timely discover hidden dangers of accidents , prevent problems before they happen, and can also provide relevant first-hand image data for post-event analysis of accidents, so the video monitoring system is an important part of the modern mine safety production monitoring system; the wireless transceiver device in the existing video monitoring system, Most of them have limited receiving range and low sensitivity, which is very inconvenient to use. Contents of the invention [0003] The object of th...
