Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of fail safe system for transformer substation, including anti-error main frame, communication adapter and off-line lockset, it is characterised in that: also include the first communication network, the second communication network, gateway coordinator, online computer key, some controllers and online lockset；Described first communication network is used for telecommunication, and the second communication network is used for field data collection, and the first communication network and the second communication network are got in touch with by gateway coordinator；Anti-error main frame realizes the remote operation to online lockset by communication adapter, the first communication network, gateway coordinator, the second communication network, controller；Online lockset gathers the status information of primary equipment, is uploaded to anti-error main frame in real time by controller, the second communication network, gateway coordinator, the first communication network, communication adapter；Grid switching operation bill is handed down to online computer key by the first communication network by anti-error main frame, and by online computer key, off-line lockset is unlocked operation；The real remote signalling of off-line lockset is uploaded to anti-error main frame by online computer key, the first communication network and communication adapter.
Anti-error main frame is equipped with the industrial computer of error resistant operation ticket software, possesses anti-false judgment function during simulation preview, prevents all kinds of maloperation from occurring during generating operation order；Possess Real-time Logic arbitration functions, according to lockset status information, current every single stepping can be carried out Real-time Logic judgement；Anti-error main frame, by serial ports and communications adapter communication, the integrated GPRS module of communications adapter, can carry out radio communication by GPRS network with gateway coordinator and online computer key, obtain online lockset state and off-line lockset reality remote signalling in real time.
Described online lockset includes remote controlled locking relay and intelligent lock, and remote controlled locking relay is for the online locking to the electrical equipment remote manipulation such as chopper and electric knife gate；Intelligent lock is for equipment states such as online locking mechanical operating mechanism, Real-time Collection ground wire, net doors.Online lockset remote operation place in transformer station, main frame as anti-error in primary cut-out, high-voltage switch etc. is remotely controlled the equipment of locking.When online lockset is operated, operator send the romote controlled locking order through logical judgment by anti-error main frame, first pass through the first communication network and operational order is issued to gateway coordinator, gateway coordinator carries out data and processes and by the second communication network, operational order be issued to controller after protocol conversion, controls the locking of online lockset.On the other hand, controller Real-time Collection online lockset state, sent to gateway coordinator by the second communication network, gateway coordinator carries out data and processes and by the first communication network, lockset information be uploaded to anti-error main frame after protocol conversion, it is achieved thereby that anti-error main frame is to on-the-spot lockset and the real-time monitoring of equipment state, the problem efficiently solving five-preventing system in prior art " off-line operation ".When wireless network breaks down, the on-line/off-line handle on intelligent controller is placed in regard to position by operator, operates online lockset by online computer key.
Off-line lockset is the place of local operation in transformer station, such as contact net electrical verification, hanging earthing conductor, local operation case locking box etc..When off-line lockset is unlocked operation, first operator are simulated preview to the operation that will carry out on anti-error main frame, operation order is generated after simulation preview is errorless, operation order is downloaded to online computer key by the first communication network or communications adapter by anti-error main frame, online computer key carries out local operation to off-line lockset after receiving operation order, often operate a step and all the real remote signalling of off-line lockset is uploaded to anti-error main frame by GPRS network, it is achieved the real-time monitoring to off-line lockset of the anti-error main frame.Anti-error main frame according to each lockset state carry out Real-time Logic accuracy of judgement errorless after, confirmation is sent to online computer key by the first communication network, online computer key just can carry out next step operation, thus can be prevented effectively from online computer key problem of " walking idle running ".
Described first communication network is GPRS network；Described second communication network is ZigBee-network.System without wiring, simple in construction, be prone to construction, given full play to the fast advantage of GPRS network long transmission distance, transfer rate and ZigBee technology automatic network-building, time delay is short, capacity is big advantage.
As shown in Figure 2, gateway coordinator has microprocessor module, GPRS communication module and ZigBee communication module, wherein microprocessor module uses Samsung's S3C2440A chip, GPRS communication module selects the MC55 chip of Siemens Company, and ZigBee communication module selects the CC2430 chip of TI company.Gateway coordinator receives, by GPRS network, the operational order that anti-error main frame issues, and carries out data through microprocessor module and processes and after communication Protocol Conversion, be issued to terminal node by ZigBee-network through router；The data that gateway coordinator can also be forwarded by ZigBee-network receiving router, through the data of microprocessor module process with communication Protocol Conversion after, by GPRS network, data are uploaded to anti-error main frame.
As it is shown on figure 3, controller controls Guan Bi and the disconnection of on-the-spot online lockset by photoisolator, the online lockset of Real-time Collection and equipment state also report to tag contact.Online lockset includes remote controlled locking relay and intelligent lock, remote controlled locking relay is for the online locking to the electrical equipment remote manipulation such as chopper and electric knife gate, intelligent lock is used for online locking mechanical operating mechanism, and can collecting device state, the state efficiently solving the equipment such as ground wire, net door cannot the problem of Real-time Collection.Intelligent controller also has on-line/off-line handle, when wireless network breaks down, handle is placed in off-line position, can be unlocked online lockset by online computer key.
Online computer key is internally integrated GPRS communication module, for off-line lockset carrying out local operation and obtaining off-line lockset state, by GPRS network, off-line lockset reality remote signalling is uploaded to anti-error main frame.Online computer key often operates a step, by GPRS network, off-line lockset state and operation information must be uploaded to anti-error main frame, so that anti-error main frame carries out Real-time Logic judgement, online computer key just can carry out next step operation after receiving the confirmation that anti-error main frame issues.Online computer key makes to be finished and is positioned over communications adapter afterwards and is charged.
