A kind of real-time monitoring and statistics of automatic channel analyzes system
Technical field
The present invention relates to a kind of real-time monitoring and statistics of automatic channel and analyze system.
Background technology
Gradual perfection along with intelligent grid, it is ensured that reliable, the instant and accurate delivery of four distant data becomes particularly to weigh
Want.Dispatch data net bears the transmission of four distant data, is the neutral net of intelligent grid.In dispatch automated system
In, the passage between main website and subordinate substation is the important means that control centre monitors substation in real time.Subordinate station (includes
Switchyard, transformer station, power plant, ground tune etc.) send remote measurement, remote signalling data by dispatch data net superior station,
Higher level station sends remote control and remote regulating data by dispatch data net to subordinate station.In running, there is part
Having interruption saltus step on-the-spot during data of standing, owing to scene is unattended station, main website is difficult to learn that affecting the quality of data asks
Topic concrete reason, it is impossible to suit the remedy to the case.
The data-transmission interruptions when passage occurs abnormal, on-the-spot service data cannot obtain, the control command of main website
Cannot send, especially when breaking down in substation, this monitoring hysteresis quality seriously increase the fault economy that causes of lock and
Equipment loses, even personal security.Immediately grasp state of data channel, find out passage and frequently throw move back the most former
Because of extremely the most urgent.Data use two-way TX and RX in the channel, use high frequency 3V signal.
