Embodiment
In prior art, the remote control of railway contact line electric isolating switch generally adopts the mode of the remote monitoring+local background monitoring based on telemechanical dedicated network passage (hereinafter referred to as " telecontrol channel "), contact net electric isolating switch is in the running of reality, owing to disturbing by electromagnetic field and lightning surge, once repeatedly there is electric isolating switch malfunction, tripping and missed the problems such as remote signalling, its shortcoming major embodiment several respects below:
When one, having operation: when control centre carries out straighforward operation to contact net electric isolating switch, after straighforward operation, whether contact net electric isolating switch there is malfunction, tripping and misses the situations such as remote signalling, and the dispatching desk on control centre and local backstage cannot get on-the-spot truth in time.
Two, without operation time: contact net electric isolating switch is not when operating, and when switch occurs malfunction, tripping and misses the situations such as remote signalling, the truth that contact net electric isolating switch is current cannot be known in control centre and local backstage.
Current processing mode is, all needs to carry out manual confirmation to as slave station operator on duty.Even if also patent discloses corresponding video monitoring system in prior art, but video monitoring system is by wireless network transmissions monitor video, and networking cost is high, is not on the actual application at present.
The main present situation of current railway contact line electric isolating switch has following feature:
1, contact net electric isolating switch slave station is configured with local background monitoring system;
2, video monitoring system can be configured at slave station, because local backstage and contact net electric isolating switch are apart near, build video channel cost compare cheap, be equipped with the conditions permit of video monitoring at local contact net electric isolating switch, and some contact net electric isolating switch is controlled to be configured with video system.
3, the local backstage of contact net electric isolating switch and control centre, only have special telecontrol channel at present; In order to ensure not affect remote control, therefore can not take telecontrol channel as video channel, and due to the bandwidth of telecontrol channel low (being generally 2M), the bandwidth requirement of video system passage cannot be met.
4, contact net electric isolating switch slave station and control centre is distant, as laid separately video designated lane, construction cost is very expensive, and technology to realize difficulty higher, be therefore that the feasibility of contact net electric isolating switch configuration video channel is more difficult in control centre.
5, electric railway telecontrol system concerns the normal production and operation of high-speed railway, therefore the requirement real-time of remote control very high (remote control delay requirement is no more than 2s), and stability, fail safe, confidentiality requirement are higher, therefore special wired telecontrol channel can only be adopted, communication port and the Internet passages such as public wireless, satellite can not be adopted, and build special wireless, satellite channel on existing basis, cost is higher.
Based on These characteristics, therefore the multiplexing telecontrol channel in local backstage and control centre is made to communicate in the present invention, only when receiving the remote signals of isolating switch or the video of taken at regular intervals isolating switch or image data send to control centre, adopt and alleviate the high problem of networking cost in this way, do not affect again the normal use of telecontrol channel.Namely for the electronic visual control of telemechanical separating switch of contact line, multiplexing existing telecontrol channel mode can only be considered, and will consider the impact of telecontrol channel minimum.Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
