Description
Technical field:
The present invention relates to a kind of observation and control technology, particularly a kind of telecontrol channel monitor alarm device.
Background technology:
In electric power scheduling automatization system, the telecontrol channel of employing comprises simulation, numeral and network channel.Automation of transformation substations equipment transmits automated information by telecontrol channel to scheduling station.Telecontrol channel is limited to many-sided reason, often occurs interrupting or anomaly.But in real work, often can not find in time, and in the time that SCADA dispatching system reflects that certain substation data information does not refresh, automation class can not determine failsafe link in time with the teams and groups that communicate by letter, cause fault handling time to extend.In addition, the reliability of telecontrol channel communication directly affects reliability, the real-time of scheduling station information.How to find in time that telecontrol channel communication is abnormal, fast processing defect, continuously reliably for dispatcher provides dispatching of power netwoks essential electric network information, become the key issue that ensures power grid security, stable, economical operation.
Summary of the invention:
The object of this invention is to provide that a kind of can immediately to find that telecontrol channel occurs abnormal so that a kind of telecontrol channel monitor alarm device of instant fast processing.
The technical scheme that realizes the object of the invention is, a kind of telecontrol channel monitor alarm device, comprise scheduling station, telecontrol channel, telemechanical communication equipment and automation of transformation substations equipment, it is characterized in that: the input of the I/0 interface of telecontrol channel monitor alarm device is connected with described telemechanical communication equipment, input, the output of the singlechip CPU in described telecontrol channel monitor alarm device are connected with output and the drive circuit input of above-mentioned I/0 interface respectively, and input, the output of relay are connected with output and the radio alarming of above-mentioned drive circuit respectively.
The present invention has compared with the prior art the telecontrol channel of discovery and occurs extremely immediately, the remarkable advantage of being convenient to get rid of.
Brief description of the drawings:
Fig. 1 is frame principle figure of the present invention.
Embodiment:
Existing telecontrol channel information transmission mode is that 101 or 104 stipulations are carried out, according to certain form agreement, transmission 0/1 code.Its basic working method is that scheduling station issues inquiry message to automation of transformation substations equipment, and automation of transformation substations equipment is made accordingly and being replied, and scheduling station is presented in corresponding man-machine interface after receiving the information of sending, i.e. Polling Protocol.Under this information transmission mode, once telecontrol channel is abnormal, automation of transformation substations equipment is the message that does not receive scheduling station and issue, or receives wrong downward message, all no longer responses.For the feature of moving conduit communication, adopt listening mode, monitor scheduling station on telecontrol channel and whether issued message, and whether automation of transformation substations equipment is made and being replied, thereby judge whether telecontrol channel exists extremely, and notify attendant to process in time by wireless mode.
In conjunction with above-mentioned accompanying drawing, operation principle of the present invention is described further, the present invention is by the I/0 interface access telemechanical communication equipment of telecontrol channel monitor alarm device, the input that this telecontrol channel monitor alarm device is singlechip CPU is connected with the input of I/0 interface and drive circuit respectively with output, input, the output of relay are connected with output and the radio alarming of drive circuit respectively, and above-mentioned drive circuit is that the model that factory of Texas Instrument produces is the drive circuit of TI/ULN2003A chip.Under normal circumstances, on telecontrol channel, message occurs incessantly, once there is not within a certain period of time message, be that account for motion passage breaks down, according to actual conditions can three minutes, two minutes or one minute as the abnormal time, in input singlechip CPU, when CPU at this moment between Duan Wei while receiving message signals, to drive circuit output action signal, make the actuating of relay, send telecontrol channel abnormal signal to maintenance department, attendant can safeguard in the very first time, guaranteed that electric power system is in reliable and stable state.
