Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings and deficiencies of the above-mentioned prior art, and provide a low-cost isolating switch isolating switch visual telecontrol monitoring method that does not need to re-build the network or modify the existing remote control network. It also provides a visual telecontrol monitoring system for the isolating switch. In the system, the local background and the dispatching center multiplex the telecontrol channel for communication, and only when receiving the remote signaling signal of the isolating switch or periodically collect the video or picture data of the isolating switch and send it to the dispatching center , using this method to alleviate the problem of high network construction costs without affecting the normal use of the telecontrol channel

Embodiment 1

[0054] Such as figure 1 As shown, the isolating switch visual remote monitoring system cooperates with the isolating switch and the remote dispatching center server to monitor all the isolating switches of the controlled station of the catenary electric isolating switch. A video system for video or image data. In this embodiment, the video system includes a plurality of cameras, and each isolating switch is equipped with a camera, and the local background monitoring system is connected to all cameras; Communication through the telecontrol channel; the remote control channel communication is multiplexed between the local background monitoring system and the remote dispatching center server;

[0055] All isolating switches are provided with associated remote signaling points and status remote signaling points for sending remote signaling signals. The associated remote signaling points can send associated remote signaling to the local background monitoring system. The system and...

Embodiment 2

[0060] On the basis of Embodiment 1, this embodiment further improves the local background monitoring system in the isolating switch visual remote monitoring system:

[0061] Such as figure 2 As shown, the local background monitoring system further includes: a remote signal analysis module, an instruction generation module, a data receiving module, a data processing module, a data sending module and a storage module.

[0062] The remote signaling signal analysis module is used to analyze the remote signaling signal, obtain the type of the remote signaling signal and the information of the isolating switch for sending the remote signaling signal, the type of the remote signaling signal includes associated remote signaling and status remote signaling, and the associated remote signaling includes "choose Operation" and "execution operation" are two state types. In this embodiment, the remote signaling signal adopts 0 to represent "selection operation" and 1 to represent "executi...

Embodiment 3

[0086] On the basis of Embodiment 2, in this embodiment, the local background monitoring system is further improved, and the local background monitoring system also includes:

[0087] The first timing module used for the timeout judgment of the isolating switch response, the first timing module is connected with the instruction generation module and the remote signaling signal analysis module, and starts timing when the remote signaling signal analysis module analyzes that the type of the remote signaling signal is "execute operation" When the remote signaling signal analysis module analyzes that the remote signaling signal type is state remote signaling or when the set time is reached, the timing is ended, and when the timing reaches the set time, an execution timeout signal is sent to the command generation module. In this embodiment, the set time is 30 seconds, that is, the remote signaling signal analysis module parses out that the remote signaling signal type is "execute o...

Abstract

The invention discloses a visual tele-control monitoring system and method for an isolating switch. The system comprises a local background monitoring system, and a video system for acquiring video or image data of the isolating switch, wherein the local background monitoring system communicates with a remote scheduling center server by multiplexing a tele-control channel and the isolating switch; the isolating switch is provided with an associated remote signaling point and a state remote signaling point capable of sending remote signals to the local background monitoring system, the associated remote signaling point sends associated remote signals, and the state remote signaling point sends state remote signals; and the local background monitoring system controls a video system according to the received remote signals and / or self timing information to acquire data of the isolating switch and send the data to the remote scheduling center server. By adopting the system and the method, a dedicated network for visual tele-control monitoring in the scheduling center is not needed, and the local background monitoring system sends the received remote signals of the isolating switch or the periodically acquired data of the isolating switch to the scheduling center, so that bandwidth resources of the tele-control channel are saved and normal use of the tele-control channel is not influenced.

Description

technical field [0001] The invention relates to the field of isolating switch remote monitoring technology, in particular to a visual remote monitoring system and method for an isolating switch. Background technique [0002] According to the national "medium and long-term railway network planning", by 2020, the national railway construction mileage will reach 120,000 kilometers. As of 2014, my country's electrified railway construction mileage has exceeded 50,000 kilometers. In the electrified railway, the catenary isolating switch is an important equipment for traction power supply catenary maintenance or segmental isolation during faults. Its operating status directly affects the railway traffic organization and power supply safety. and high reliability requirements. [0003] At present, the remote control of railway isolating switches generally adopts the method of remote monitoring based on the dedicated telecontrol network channel + local background monitoring. During...
