Summary of the invention
In order to avoid transformer station easily occur tear the equipment such as hanging earthing conductor open time the maloperation that occurs; reduce transformer station's maloperation number of times; improve the safety coefficient of electrical production, the protection person and device security, the invention provides a kind of ground wire in substation supervisory system and method for supervising.
Technical solution of the present invention is:
A kind of ground wire in substation supervisory system, comprise radio frequency reading receiver, radio-frequency card, be arranged on the ground wire control module of ground wire indoor, described radio frequency reading receiver to be arranged in ground wire cabinet and with the distance of ground wire riding position in effective range of receiving, radio-frequency card is placed on ground wire, described ground wire control module is formed by as the embedded computer of central control unit and multiple 485 communication ports, be connected with radio frequency reading receiver by 485 communication ports, ground wire control module is connected with the background computer of master-control room by wireless communication mode, and be connected with liquid crystal touch display screen with the phonetic warning system of master-control room by background computer.
Described radio-frequency card is arranged in a nylon box, and have a through hole in the middle of described nylon box, the through hole of described ground wire and described nylon box is affixed, plays the effect isolated with metal, ensures the accuracy of scanning; Because nylon material has protection against the tide, the feature such as antifreeze, sun-proof, be applicable to outdoor application, serve the effect isolated with metal, also ensure that the accuracy of scanning, and durable in use.
A kind of ground wire in substation method for supervising, its special character is:
1, carry out real time scan by radio-frequency card to the ground wire putting into ground wire cabinet by the radio frequency reading receiver be arranged in ground wire cabinet, sweep signal passes to ground wire control module by 485 communication ports; Show that ground wire is indoor at ground wire as ground wire control module receives sweep signal, otherwise show that ground wire has left ground wire room;
2, when having ground wire to leave or to put back to ground wire room, ground wire control module sends signal by wireless communication mode to background computer, and by phonetic warning system automatic speech prompting, gives described background computer by the ground wire situation report-back of ground wire room;
3, on the liquid crystal touch display screen key frame of master-control room, adopt object simulating graphics mode by described background computer and arrange and quantity according to ground wire in actual putting position display ground wire room, and the service condition of the current live ground wire received with master-control room and ground cutter is compared, if ground wire situation is consistent with field condition in ground wire room, then belong to normal condition, main frame is not reported to the police, and only points out; Otherwise main frame is reported to the police and started voice message type of error, thus realize the effective management to ground wire.
Described 485 communication ports take parallel scan mode; To improve sweep time and accuracy, realize the rapid scanning to ground wire room ground wire, substantially reduce the scan period of ground wire, meet the requirement of the quick reflection of user.
The invention has the beneficial effects as follows:
1, less radio-frequency scanning technique is applied to ground wire room locality on line position, solves and ground wire is monitored it is all that it is bad that time length can produce contact, the inaccurate problem of state with mechanical contact contact acquisition mode in the past.The application of less radio-frequency scanning technique, eliminates the weakness of mechanical contact, has service time long, easy to use, the feature that accuracy rate is high.Can real time monitoring ground wire room state of ground wire.
2, system can be connected with liquid crystal touch display screen, make ground wire room ground wire and liquid crystal touch display screen composition set of system, package unit take background computer as core, ground wire room control module is connected with background computer wireless communication mode, can accurately accept and send data, floor is penetrated without in different floor gap punching, ground wire room control module carries out real time scan by 485 interfaces to ground wire, control audio alert prompt facility simultaneously, and be responsible for carrying out communication with background computer, by the situation report-back of ground wire room to background host computer, realize using the ground wire in ground wire room and the Real-Time Monitoring of state of placement situation and grounding switch, ensure the proper use of of ground wire, the mistake hanging ground-wire avoiding various factors to cause, tear the operating mistakes such as wrong ground wire open, the available protecting person and equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
