Background technology
Transformer station has been the important place of voltage transitions.Transformer, line breaker, disconnecting link, arrester, capacitor, switchgear etc. are run in transformer station, for ensureing transformer station's stable operation, safety completes conversion and the transmission of voltage, electric company needs to carry out periodic inspection and maintenance to the various kinds of equipment in transformer station, completes the operation of relevant device.Because transformer substation voltage is higher, in operation, the safety of personnel and equipment must be guaranteed, avoid occurring security incident.Therefore electric company is when operating substation equipment, have employed the means such as operation order, work ticket, security control person, ensures that personnel's operating equipment carries out under being in safety, controllable state.Install safe fence around substation equipment, operating personnel enters fence and carries out equipment operating.Equipment fence serves certain protective effect for job safety.But equipment fence gate adopts traditional latch mode to carry out locking, arbitrarily can open, lack necessary safety monitoring mechanism, cannot the on off state of grasp fence promptly and accurately and latch, can not remind immediately for being strayed into equipment fence situation, there is job safety and device security hidden danger.When substation equipment operation and maintenance, the on off state of real-time perception equipment fence latch, wireless transmission plug-in switch data, to remind in time for substation equipment fence abnormal start-up be the problem needing in substation equipment safety work work to solve.
Summary of the invention
The present invention proposes a kind of transformer station fence gate latch monitoring method.
The object of the invention is the on-line monitoring technique based on sensing, wireless telecommunications, at fence latch node place integrated sensor, after latch inserts, sensor automatic sensing latch insert state.Status data uploads in monitoring system by the wireless communication module subsidiary by sensor, completes the on-line real time monitoring of power transformation station equipment fence latch state.For the situation of non-implement fence abnormal start-up, monitoring system, after receiving fence latch status data, is reported to the police by the mode such as system message, note, reminds transformer station's operation maintenance personnel to process in time.Stop the generation that substation equipment fence enters situation by mistake.
In order to achieve the above object, the present invention is by the following technical solutions:
Adopt wireless latch sensing joint, substitute original metal joint.Inside has feeler, is spring paddle mode, Compress Spring paddle after latch inserts, connecting circuit board after paddle, and state is 0, and expression is not inserted, state is 1, represents and inserts.When latch inserts joint, activating sensor, pressing spring paddle, sensor states changes to 1 automatically.When latch is transferred to, eject spring paddle, activating sensor, sensor states changes to 0 automatically
The inner integrated wireless communication module of wireless latch sensing joint, module is based on 2.4GHz wireless data communication mode, 2.4GHz wireless communication module is set up communication with the concentrator in transformer station and is connected, timing uploads latch status data to the concentrator devices in transformer station, avoids on-the-spot numeral system communication to connect up.
Wireless fence latch sensing joint, adopts passive design, is powered, do not need external power supply by internal battery.Plug and socket connector adopts integrated circuit structure, and power consumption is low, long service life.
Latch sensing joint is directly installed on fence, and each sensing joint has unique coding, corresponding each substation equipment fence.When fence occurring and being strayed into, then encode according to fence latch sensing, the equipment fence that automatic-prompting is corresponding.
Fence latch sensing joint timed sending fence plug-in switch status data is to concentrator, and concentrator devices is connected, by the on off state data upload of equipment fence to monitoring system with monitoring main frame by RS-485 bus.
Fence latch status data carries out processing and preserving by monitoring system, shows the switch conditions of each equipment fence with the interface of figure in real time.When the equipment fence Status Change operated without permission, send early warning signal, remind administrative staff to process.
Architectural feature: fence latch is provided with the latch post of slip, jack on latch post alignment receptacles sheet, wireless latch sensing joint is connected at the corresponding position of fence latch, at jack built with spring plectrum, the insertion of spring plectrum or extract generation signal, signal flows to wireless communication module by sensor, carried out monitoring and monitoring to supervisory control comuter at jack or the Signal transmissions not in jack by latch by wireless communication module, battery is respectively wireless communication module and sensor power.
Good effect, the present invention can detect power equipment and transformer station's fence locking latch state, this monitoring host computer is transmitted by the mode of wireless transmission, latch insertion can be detected by main frame or extract the state of jack, conveniently observing and record and detect entering with or without thinking, preventing power equipment to be destroyed, and prevent the generation of security incident, have structure simple, easy to use, maintenance is easy to feature.The suitable application of installation as substation equipment safety monitoring.
