Abstract
In the invention, using the channel self and the CD carrier signal complete the detection. The single chip technique and the DSP sampling technique are utilized to collect quantities of state and channel levels in eight routes of RTU. Whether the channel is normal or not is judged by monitoring the signal level in the receiving channel of RTU. The monitoring device possesses two ends for input signal and one end for output signal. The two input ends are connected to the receiving and sending channels of RTU respectively. The output signal is connected to the sending channel of the device channel. The connectors of the relay supported by the power taken from the power source of the RTU are connected to the said receiving and sending channels. If the power is in failure, then the exciting, receiving and sending channels of the relay are in short circuit. The invention uses standard communication protocol and the main station can reset the RTU power sources.
Description
Technical field
The present invention relates to the design and the manufacturing technology field of power system management technical field of automation and related device, particularly relate to and utilize telecontrol channel to realize RTU and passage distant place failure diagnosis
Technical field.
Background technology
The channel failure type roughly has following several: 1, send out passage and interrupt; 2, receiving passage interrupts; 3, the channel levels attenuation is big, and makes the sending and receiving level too low; 4, in the passage interference signal is arranged and make communication that error code be arranged; 5, the sending and receiving passage all breaks.
Cause the fault of the communication disruption of RTU own to have four kinds: 1, RTU crashes; 2, power of alterating and direct current dead electricity; 3, working power fault; 4, modem failure.
At present, there is not the diagnostic device of typing in electric power system, to use.There is minority unit to utilize the public telephone passage to realize RTU and passage distant place failure diagnosis.Its shortcoming is, because public telephone channel failure rate is higher, brings added burden for O﹠M nurse far away, is unfavorable for system stable operation.
Summary of the invention
The objective of the invention is, a kind of method of utilizing telecontrol channel to realize RTU and passage distant place failure diagnosis is provided.Its technical scheme is:
Utilize telecontrol channel self, utilize the CD carrier signal to finish detection.Mainly solve to send out passage and interrupt, receive that passage interrupts, the channel levels attenuation is big and make that the transmitting-receiving level is too low, interference signal arranged in the passage and the channel failure that makes communication have error code and sending and receiving passage all to break; Solve the own communication disruption fault of RTU of RTU deadlock, power of alterating and direct current dead electricity, working power fault and modulation fault simultaneously.
Advantage of the present invention is, overall technology is reliable and stable, and equipment therefor is cheap, installation is simple, convenient, possesses remote measurement, remote signalling, distant control function.During the diagnostic device fault, can not influence the normal operation of RTU.
