System of the present invention at work, program such as Fig. 4 that data are handled of client stations server, and the workflow of the master server of centralized control center such as Fig. 5.It issues acquisition in the mode of poll to serial server, so that power equipment is carried out remote signalling, remote measurement.This acquisition has comprised the address and the specific instructions of acquisition module.Serial server will be transmitted to acquisition module by bus in the mode of broadcasting.Acquisition module will be made comparisons with the address of self after receiving acquisition, and acquisition is then resolved in the order that belongs to self, and the register that refers in particular to from acquisition reads register data and according to agreement return register data.Serial server passes to the client stations server after receiving the data of acquisition module, and the client stations server is finished the parsing work of data, and analysis result is upgraded real-time data base, and is saved to historical data base.According to analysis result, send remote control, remote regulating information and interrogating signal simultaneously, make control module control and regulate corresponding power equipment, make power equipment keep normal condition according to this remote information, remote regulating information to control module.The client stations server also is forwarded to centralized control center's server with above-mentioned analysis result.
Video camera is view data to be uploaded to the client stations server by video server initiatively, and video server receives and processing video data, and handles warning message.The client stations server will be finished the restriction warning of data simultaneously and handle, if the data of resolving exceed its specific value range, to report to the police and handle operation, as: promote the warning picture, play the alarm sound file, write down alarm condition etc., and video and warning message are uploaded to the centralized control center.
Meanwhile, the client stations server also will be transmitted the order that the centralized control center issues.If receive centralized control center's transmitting order to lower levels, then carry out command analysis work and carry out this order by control module, and will transmit the result and implementation status feeds back to the centralized control center by serial server.If the inquiry order, the client stations server then is uploaded to the centralized control center to the running state information of self.
The client stations server receives, transmits data and controls through router by multichannel, if the master network VPN traffic normally then is the main data transmission of carrying out with the master network, if master network communication is undesired, then starts backup network and carries out data communication.
The master server of centralized control center then is responsible for issuing of order and to the reception and the processing of client stations data.Fig. 5 is the process flow diagram of this master server.A plurality of monitoring equipments of centralized control center are to send instructions under master server according to different operation grades, mainly strictness control is carried out in instruction and operation grade, the operation that meets the demands then sends instructs to the corresponding client station, and the product survivor and the command content of recording instruction, wait the implementation status of pending client stations simultaneously, and preserve implementation status sending instructions down.Client stations is then continual transmits data to the centralized control center, and the collection control will be carried out data parsing and processing, if produce the processing of then reporting to the police of reporting to the police, as promoting the warning picture, playing alarm sound.Meanwhile, master server according to the operation grade of monitoring equipment and authority to its distributing data.
Be the example illustrative system course of work with the power equipment transformer below:
Increase along with load, the temperature of transformer and electric current also will increase, if transformer temperature and electric current exceed the safe operation setting value, transformer itself will produce temperature and electric current warning message automatically, this information is passed to acquisition module through connection terminal, and acquisition module receives heat alarm, and displacement will take place the mode bit of acquisition module, the relevant register address value that is acquisition module can be revised as 1, and (normally being 0) displacement taken place reported to the police.Client stations inquires about and reads the buffer status and the register value of acquisition module in the mode of poll, if collect warning message, then read the warning name information (comprising the substation title of produce reporting to the police, line name, loop title etc.) of warning register correspondence from database, upgrade the real-time data base of client stations data server, if this warning variable needs the display alarm picture, then be positioned to the picture at warning variable place, and report to the police with red color flicker expression according to the warning name information.If this variable need be play alarm sound, then play the alarm sound file according to configuration.The client stations data server is handled after the alert data, need be saved to historical data base, transmits this warning message to the centralized control center simultaneously.After the centralized control center receives the alert data of client stations, master server will promptly upgrade the variable alarm condition of real-time data base to alarm information processing, and the display alarm picture is play alarm sound, is saved to historical data base, transmits warning message to monitoring equipment.Monitoring equipment can monitor alarm information time of origin, warning message take place local, warning message type, and, implement different operations according to alarm level.The monitor staff can issue different warning processing commands according to type of alarm, reports to the police, confirms to report to the police, disconnect overload switch etc. as removing.Behind the guidance command that master server reception monitoring equipment issues, at first detect the legitimacy of transmitting order to lower levels, that satisfies the operating right scope will resolve the telecontrol order, and issue corresponding substation end client stations server, this server is forwarded to control module with the destination address of resolve command by serial server, and control module changes the status register value, produces control signal, finish control operation, and execution result is returned.
Like this, centralized control center's unification is monitored in real time to client transformer station, and have all functions such as remote measurement, remote signalling, remote control, remote regulating, management, guarantee the unmanned ground safe operation of client transformer station, become fully independently Automatic monitoring systems, for the normal operation of substation equipment and the timely processing of fault provide reliable guarantee.While gps satellite clock system; Correct effectively satellite time can be provided, to the equipment that is monitored terminal carry out to the time make the equipment operation clock correctly reliable, can in the very first time, reach the spot by GPS and generalized information system when peculiar situation or breakdown repair appear in client transformer station simultaneously, the loss that minimizing brought because of the not yet done delay time at stop of road is so that client's loss drops to is minimum.
