Accompanying drawing 1 is structured flowchart of the present utility model.
The method flow diagram that accompanying drawing 2 adopts for the utility model.
In the above accompanying drawing: 1, the first R-T unit; 2, the second R-T unit; 3, the first sending module; 4, the first receiver module; 5, the second sending module; 6, the second receiver module; 7, testing fixture; 8, timing unit; 9, master control device; 10, background computer; 11, Surveillance center; 12, relay protection device; 13, counting unit.
Embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Embodiment one: several original in electric system relay protection devices 12 all are connected with master control device 9, and master control device 9 is connected with background computer 10, Surveillance center 11, and master control device 9 is used for controlling the operation of whole electric system.As shown in Figure 1, the relay protection device real-time monitoring device of now setting up comprises the first R-T unit 1 and the second R-T unit 2, and the testing fixture 7 that can carry out to relay protection device 12 self-examination.The first R-T unit 1 is connected with master control device 9, comprises that specifically the first sending module 3 and the first receiver module 4, the second R-T units 2 are arranged on the relay protection device 12, specifically comprise the second sending module 5 and the second receiver module 6.The first sending module 3 is connected by self-test signal with the second receiver module 6; the second sending module 5 is connected by the self-detection result signal with the first receiver module 4; wherein; the first sending module 3 is for broadcasting the module of issuing an order; its self-test signal that sends is all issued an order with the form of broadcasting, and the self-detection result signal that the second sending module 5 sends obtains according to the check result that is arranged on the testing fixture 7 on the relay protection device 12.Simultaneously, the first R-T unit 1 also is connected with a timing unit 8, is used for the frequency of control the first R-T unit 1 transmitted signal.
As shown in Figure 2; the principle of work of this relay protection device real-time monitoring device is as follows: at first; the first sending module 3 of the first R-T unit 1 sends self-test signal by the form of broadcasting; usually issued an order once every 10 seconds by timing unit 8 controls; after the second receiver module 6 of the second R-T unit 2 receives self-test signal signal is transferred to testing fixture 7; testing fixture 7 begins relay protection device 12 is carried out self-examination; check complete after; the check result that the second sending module 5 of the second R-T unit 2 draws according to testing fixture 7 is transferred to the self-detection result signal the first receiver module 4 of the first R-T unit 1 again; if the self-detection result signal is normal; then represent relay protection device 12 normal operations; if the self-detection result signal is unusual; relay protection device 12 operation exceptions of then expression correspondence; this moment the first R-T unit 1 again with this abnormal results signal feedback to master control device 9; master control device 9 namely sends the alarm signal of this relay protection device 12 " deadlock " simultaneously to background computer 10 and Surveillance center 11, the staff of Surveillance center 11 finds just can notify immediately relevant maintainer to come reparing hidden danger after the alarm signal.
The first R-T unit can also connect a counting unit 13; N time (N continuous is inferior to be used for avoiding interference when the first sending module 3 is issued an order continuously; the problem such as communication abnormality intermittently; by issue an order time counting number of 13 pairs of counting units); when the first receiver module 4 is not all received the feedback of self-detection result signal; then the first R-T unit 1 also can be judged this relay protection device 12 operation exceptions; simultaneously can be with this abnormal results signal feedback to master control device 9; master control device 9 namely sends the alarm signal of this relay protection device 12 " deadlock " simultaneously to background computer 10 and Surveillance center 11, the staff of Surveillance center 11 finds just can notify immediately relevant maintainer to come reparing hidden danger after the alarm signal.
Because the utility model has adopted the first R-T unit 1 that is connected with master control device 9; and be provided with the second R-T unit 2 and be used for the testing fixture 7 that the oneself detects at relay protection device 12; the mode of issuing an order by broadcasting is controlled relay protection device 12 and is carried out the oneself and detect; feed back to judge its operation conditions according to the information of relay protection device 12 again; realized the Real-Time Monitoring of relay protection device 12 operations; so that any operation exception all can in time be found; avoid protective relaying device to cause its incorrect operation because of long-time abnormal work; also can avoid manual patrol to erroneous judgement and the omission of equipment state, greatly promote the security performance of electric system.
