Description
Technical field
The present invention relates to supervisory control of substation field, specifically refer to transformer station's integrated synthesis supervisory system.
Background technology
Along with the fast development of computer technology and the network communications technology, Automation of Electric Systems construction development is all the more perfect.Traditional monitoring system of electric substation is subject to the limitation of technical development, can only carry out field monitor, simple warning message transmission, cannot realize remote distance video transfer signal, for the understanding of front end concrete condition, the confirmation of event is very difficult, in addition traditional monitoring system of electric substation needs manual operation, has certain danger, has virtually reduced the security of system.At present, how by telemonitoring, remote control, antitheft and report to the police and organically combine, both accomplishing can telemonitoring and remote control, can, to environment integral monitoring and warning, become the main direction of current monitoring system of electric substation development again.
Summary of the invention
The object of the present invention is to provide a kind of both can telemonitoring and remote control, transformer station's integrated synthesis supervisory system that again can be to environment integral monitoring and warning.
The present invention is achieved through the following technical solutions:
Transformer station's integrated synthesis supervisory system, comprise local monitor main frame and remote control device, local monitor main frame is connected by internet with remote control device, local monitor main frame respectively with video matrix switcher, analog to digital converter a, analog to digital converter b, analog to digital converter c, driving circuit, display, warning device, video compression card, keyboard connects, on video matrix switcher, be connected to video camera, analog to digital converter a is connected with temperature-sensing probe, analog to digital converter b is connected with Smoke Detector, analog to digital converter c is connected with infrared probe, driving circuit is connected with on-site control device.
Further, described on-site control device is relay.Relay is a kind of electric control device, is when the variation of input quantity reaches regulation requirement, makes controlled volume that a kind of electrical equipment that predetermined step changes occurs in electric output circuit, is actually a kind of " automatic switch " that with little electric current, go to control large electric current running.Due to the singularity of substation, by manual operation, cut-off circuit and there is certain danger, and cut-off circuit by relay, can be good at evading this potential danger.
Further, described remote control device is notebook computer.Notebook computer is compared with common desktop computer, carries more convenient.As long as there is network, in different regions, all can realize Remote.
Further, described local monitor main frame is connected with telephone sound card, and telephone sound card is connected with public switched telephone network by telephone wire.When situation is abnormal, telephone sound card carries out auto dialing, beats landline telephone (or mobile phone) and notifies duty personnel or technician, automatically completes notification procedure.
Further, described warning device comprises phonetic alarm device and electric bell.When situation is abnormal, local monitor main frame can emergency, harmfulness according to circumstances be reported to the police in different ways.For not being that particularly urgent and harmfulness are not that king-sized abnormal conditions adopt audio alert; Abnormal conditions large for danger or particularly urgent adopt electric bell alarming, improve duty personnel's alertness.
Further, described display is liquid crystal display.Liquid crystal display is the display device of planar ultra-thin, and it is comprised of colour or the monochrome pixels of some, is positioned over light source or reflecting surface the place ahead.It is different from CRT technology, and LCD picture can not glimmer, and can reduce the injury of display to eyes, and eyes are not easy fatigue, can effectively alleviate duty personnel because the visual fatigue that long-time monitoring brings.
Further, described infrared probe is passive type infrared eye.Passive type infrared eye does not need additional infra red radiation light source, and itself does not launch any energy to the external world, but by detector direct detection the infrared radiation from moving target.Passive type infrared eye detection performance is good, be easy to deploy troops on garrison duty, price economy material benefit.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) one aspect of the present invention has realized telemonitoring and remote control, can environment integral monitoring and warning be coincide with the main direction of current monitoring system of electric substation development again on the other hand, can meet the needs of transformer station's future development;
(2) the present invention, without manually cut-offfing circuit, has strengthened security of system greatly, and one side has effectively been avoided the danger bringing due to manual operation, has realized again on the other hand the robotization of operation;
(3) the present invention is by installing telephone sound card in local monitor main frame inside, and telephone sound card is connected with public switched telephone network by telephone wire, when situation is abnormal, can notify timely duty personnel and technician.
