Description
Technical field
The present invention relates to a kind of cable theft-prevention device, especially a kind of passive road lighting cable alarm.
Background technology
At present, cable theft-prevention device of the prior art all is to increase the UPS accumulator by transformer terminal, utilizes single lamp carrier-wave transmission net and voltage transformer wireless transmission network to realize the anti-theft feature of cable.To not using the street lamp control net of this system, also can realize anti-theft feature by increase transformer cable theft prevention RTU, control center's computer system; More than two kinds of road lighting cable anti-theft devices, structure is formed complicated, costs an arm and a leg.Therefore, designing a kind of structure and form simple, cheap passive road lighting cable alarm, is the present technical issues that need to address.
Summary of the invention
Technical matters to be solved by this invention provides a kind of structure and forms simple, cheap passive road lighting cable alarm.
The technical scheme that the present invention solves its technical matters is:
Passive road lighting cable alarm, mainly comprise resistance, relay and connecting terminal block, one termination of resistance connects the X2 terminal of connecting terminal block, one end of the normally closed contact of another relay termination of resistance, the X1 terminal of another termination connecting terminal block of the normally closed contact of relay, the X1 terminal of the connecting terminal block of passive road lighting cable alarm is connected with the wherein end of two strands of electric wires of road lighting cable respectively with the X2 terminal, passive road lighting cable alarm in being arranged on Master Control Room be connected signal supervisory instrument between above-mentioned two strands of electric wires and the power light of street lamp switch board forms the stolen signal source of full-time time cable.When the road lamp switch that closes was given street lamp power supply, road lamp power supply, power light was bright, and it is stolen to prove that cable does not have, and cable is stolen if power light extinguishes proof, and the normally closed contact of relay and the normally closed contact of the relay in the signal supervisory instrument are in off-state at this moment; When disconnecting road lamp switch, the normally closed contact of relay and the normally closed contact of the relay in the signal supervisory instrument are in closure state, signal supervisory instrument forms the loop by the normally closed contact of relay, the signal of signal supervisory instrument shows and is communicated with, the proof cable does not have stolen, if cable is cut off, signal supervisory instrument can not form the closed-loop path, the signal of signal supervisory instrument shows disconnection, proves that cable is stolen.
Preferably, between the other end of the normally closed contact of connection terminal X1 and relay, be in series with the restorability fuse.
Further preferably, also comprise the passive signal reverberator, the X3 terminal of one termination connecting terminal block of passive signal reverberator, the X4 terminal of another termination connecting terminal block of passive signal reverberator, wherein the X4 terminal connects the end of the zero line of road lighting cable, the X3 terminal connects the end of any live wire of road lighting cable, and above-mentioned live wire and zero line are connected the normally closed contact two ends of the relay in the street lamp switch board respectively.When the road lamp switch that closes was given street lamp power supply, road lamp power supply, the normally closed contact of the relay in the street lamp switch board was in off-state, and the passive signal reverberator does not constitute the closed-loop path but its two ends have normal voltage, and the passive signal reverberator does not send signal; When disconnecting road lamp switch, the normally closed contact of the relay in the street lamp switch board is in closure state, the two ends of passive signal reverberator do not have normal voltage, but the passive signal reverberator constitutes the closed-loop path by the normally closed contact of the relay in the street lamp switch board, and the passive signal reverberator does not send signal yet; When cable is cut off, the two ends of passive signal reverberator neither have normal voltage, also enough simultaneously do not become the closed-loop path, send signal, prove that cable is stolen.
Compared with prior art, at first, because the cable theft-prevention device adopts the carrier of the electric power cable of entity as data transmission, be not subjected to the influence of barrier, data transmission is stable; And, electric power cable transfer rate height, better satisfied communication needs.The second, because the cable theft-prevention device uses entity electric power cable transmission signals, exempt the worry of part position to wireless radiation.In addition, product is low in energy consumption, and power consumption belongs to the energy-conserving and environment-protective design less than 2W during operate as normal.The 3rd, can learn by cable loop whether road lighting cable is stolen behind the bright lamp of street lamp on the evening illuminating line, the low-voltage circuit of the back of turning off the light daytime by cable carries out the antitheft monitoring of road lighting cable, realized round-the-clock antitheft monitoring; In addition, the present invention powerful, simple in structure, effective, need not the power supply of outside savings power supply.

Embodiment
As shown in the figure, passive road lighting cable alarm, mainly comprise resistance 4, relay 2 and connecting terminal block, one termination of resistance 4 connects the X2 terminal of connecting terminal block, one end of the normally closed contact of another relay termination 2 of resistance 4, the X1 terminal of another termination connecting terminal block of the normally closed contact of relay 2, the X1 terminal of the connecting terminal block of passive road lighting cable alarm is connected with the wherein end of two strands of electric wires of road lighting cable respectively with the X2 terminal, passive road lighting cable alarm in being arranged on Master Control Room be connected signal supervisory instrument 5 between above-mentioned two strands of electric wires and the power light 6 of street lamp switch board forms the stolen signal source of full-time time cable.Between the other end of the normally closed contact of connection terminal X1 and relay 2, be in series with restorability fuse 3.When the road lamp switch 7 that closes is given street lamp power supply, road lamp power supply, power light 6 is bright, the proof cable does not have stolen, and cable is stolen if power light 6 extinguishes proof, and the normally closed contact of relay 2 and the normally closed contact of the relay in the signal supervisory instrument 5 are in off-state at this moment; When disconnecting road lamp switch 7, the normally closed contact of the relay in the normally closed contact of relay 2 and the signal supervisory instrument 5 is in closure state, signal supervisory instrument 5 forms the loop by the normally closed contact of relay 2, the signal of signal supervisory instrument 5 shows and is communicated with, the proof cable does not have stolen, if cable is cut off, signal supervisory instrument 5 can not form the closed-loop path, the signal of signal supervisory instrument 5 shows disconnection, proves that cable is stolen.
