Temperature early-warning centralized display system

Abstract

The invention discloses a temperature early-warning centralized display system, which mainly comprises a plurality of digital temperature acquisition devices and a system data receiver, wherein data transmission between the digital temperature acquisition devices and the system data receiver is realized in a wireless data communication mode; the system data receiver comprises a wireless communication module (U6), an intelligent video graphics array (VGA) control panel and an alarm module which are electrically connected with a singlechip (U3); the intelligent VGA control panel directly drives a liquid crystal display through an interface P1, and the liquid crystal display displays temperature acquired by each digital temperature acquisition device and real time; and the system data receiver is arranged in the liquid crystal display. The device for monitoring the temperature of each measured point in real time gives a sound alarm when reaching an alarm temperature to remind an operator in charge so as to avoid accidents; under the condition that high-voltage equipment is electrified, real-time on-line temperature monitoring, temperature rise early warning and computer networking are realized; and the device is digital intelligent equipment.

Description

technical field [0001] The invention belongs to a temperature early warning centralized display system for high-voltage power transmission and distribution equipment, and relates to a temperature early warning centralized display system with online real-time temperature monitoring, sound alarm and high temperature alarm. Background technique [0002] With the rapid development of today's science and technology, the equipment in the high-voltage transmission and distribution industry is also updated day by day. Various types of switch cabinets have replaced the older generation of equipment because of their large capacity, small size, tight sealing, and sensitive action. The ensuing redness and heat of the contacts is also difficult to detect and measure, resulting in many major accidents in the power transmission and distribution industry. [0003] At present, ordinary optical fiber on-line measurement, far-infrared on-line temperature measurement, far-infrared imaging teste...

Problems solved by technology

[0002] With the rapid development of today's science and technology, the equipment in the high-voltage transmission and distribution industry is also updated day by day. Various types of switch cabinets have replaced the older generation of equipment because of their large capacity, small size, tight sealing, and sensitive action. The ensuing problem of hot and red contacts is difficult to detect and measure, resulting in many major accidents in the power transmission and distribution industry

[0003] At present, ordinary optical fiber on-line measurement, far-infrared on-line temperature measurement, and far-infrared imaging tester and other test methods are in the category of non-monitoring for the contacts, joints, and cable heads of mid-mounted high-voltage switchgear produced in recent years at home and abroad. High-voltage switchgears have safety hazards to varying degrees
