Comprehensive security monitoring system for substation

Abstract

The invention relates to a comprehensive security monitoring system for a substation. The comprehensive security monitoring system comprises a perimeter security monitoring module, a running equipment temperature online monitoring module, a security measurement and control host and an information management module, wherein the perimeter security monitoring module comprises a first microprocessor and a laser fence; the laser fence is connected with the first microprocessor; the perimeter security monitoring module is used for detecting intrusion information in the perimeter of the substation; the running equipment temperature online monitoring module comprises a second microprocessor and a temperature measurement unit, which are connected with each other; the running equipment temperature online monitoring module is used for monitoring a real-time temperature of running equipment; the security measurement and control host is connected with the first microprocessor and the second microprocessor in a wireless communication manner and is used for receiving and processing the intrusion information and temperature information; and the information management module is connected with the security measurement and control host through an optical fiber network, and is used for receiving the information of the security measurement and control host and achieving information sharing. Compared with the prior art, the comprehensive security monitoring system has the advantages of being integrated in system, open in interface, convenient to maintain and the like.

Description

technical field [0001] The invention belongs to the field of network technology and embedded systems, in particular to a comprehensive safety monitoring system for substations. Background technique [0002] With the development of smart substation construction work, the requirements for power supply reliability are getting higher and higher, and the importance of perimeter security and equipment operation safety has become increasingly prominent. Smart substations require secondary equipment produced by various manufacturers to be able to achieve interoperability and information sharing. . Most of the existing perimeter security systems are relatively isolated and self-contained, and it is difficult to integrate into the existing information management platform of the substation. Especially with the popularization of the IEC61850 standard, this problem becomes more prominent. Furthermore, most of the existing equipment temperature monitoring adopts infrared temperature mea...

Problems solved by technology

Moreover, most of the existing equipment temperature monitoring adopts the method of infrared temperature measurement and fiber grating temperature measurement. The former is easily affected by factors such as the temperature, humidity and background radiation of the detection environment, and the measurement accuracy is not high and real-time online monitoring cannot be realized; the latter The cost is high, the wiring is difficult, and there will be "creeping" phenomenon, which will cause insulation problems
