Abstract
The utility model discloses a telecontrol-channel monitoring and alarming device. The telecontrol-channel monitoring and alarming device comprises a scheduling main station, a telecontrol channel, a telecontrol communicator and substation automation equipment, wherein the input end of an I/O interface of the telecontrol-channel monitoring and alarming device is connected with the telecontrol communicator; the input end and the output end of a CPU (Central Processing Unit) of a single chip microcomputer in the telecontrol-channel monitoring and alarming device are respectively connected with the output end of the I/O interface and the input end of a driving circuit; and the input end and the output end of a relay are respectively connected with the output end of the driving circuit and a wireless alarm. Compared with the prior art, the telecontrol-channel monitoring and alarming device disclosed by the utility model has the obvious advantage that when the telecontrol channel is abnormal, the abnormity is conveniently eliminated.
Description
Technical field:
The utility model 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 often can not in time find in real work, and when the SCADA dispatching system reflects that certain substation data information does not refresh, automation class can not in time determine failsafe link with the teams and groups that communicate by letter, and causes 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 the telecontrol channel communication is abnormal, the fast processing defective, continuously reliably for the 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 purpose of this utility model is to provide a kind ofly can find immediately 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 utility model purpose 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, the input of the singlechip CPU in described telecontrol channel monitor alarm device, output are connected with the drive circuit input with the output of above-mentioned I/0 interface respectively, and the input of relay, output are connected with radio alarming with the output of above-mentioned drive circuit respectively.
It is instant that the utility model has the telecontrol channel of discovery abnormal compared with the prior art, the remarkable advantage of being convenient to get rid of.
Description of drawings:
Fig. 1 is frame principle figure of the present utility model.
Embodiment:
Existing telecontrol channel information transmission mode is that 101 or 104 stipulations are carried out, namely according to certain form agreement, transmission 0/1 code.Its basic working method is that scheduling station issues the 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 on corresponding man-machine interface after receiving the information of sending, i.e. Polling Protocol.Under this information transmission mode, in case telecontrol channel is abnormal, automation of transformation substations equipment will not receive the message that scheduling station issues, or receive wrong downward message, all no longer response.Characteristics for the moving conduit communication, adopt listening mode, monitor on telecontrol channel, whether scheduling station has issued message, and whether automation of transformation substations equipment is made and being replied, thereby judge whether telecontrol channel exists extremely, and notify the attendant in time to process by wireless mode.
In conjunction with above-mentioned accompanying drawing, operation principle of the present utility model is described further, the utility model is with 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 output and is connected input with the I/0 interface with drive circuit and is connected, the input of relay, output are connected with radio alarming with the output 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, message generation incessantly on telecontrol channel, in case message does not occur within a certain period of time, be that the account for motion passage breaks down, according to actual conditions can three minutes, two minutes or one minute as the abnormal time, in the input singlechip CPU, when CPU at this moment between Duan Wei when receiving message signals, to drive circuit output action signal, make the actuating of relay, send the telecontrol channel abnormal signal to maintenance department, the attendant can safeguard in the very first time, guaranteed that electric power system is in reliable and stable state.
