Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1-4, the utility model comprises the Centralized Controller for launching alerting signal and the id signal source for output cable status signal; Two input ends of Centralized Controller connect live wire and the zero line of ac cable respectively, several street lamps are parallel with between ac cable starting point and terminal, ac cable end connects the first binding post and second binding post of relay respectively, the signal input part of the 3rd binding post connection identifier signal source of relay; The output terminal of Centralized Controller is connected to the GSM sender unit that can send signal; The signal output part in id signal source is connected on ac cable; The power input in id signal source is connected to ac cable, and circuit between the first binding post of relay and ac cable is in series with fuse FU and inductor.Two input ends of Centralized Controller connect live wire and the zero line of ac cable respectively, and wherein input end are provided with the first K switch 1-1, first binding post of the first K switch 1-1 through electric wire successively through second switch K1-2, resistance R and the first power supply Ec ground connection; Second binding post of the first K switch 1-1 and another input end are all connected to the input end of Hi-pass filter, and Hi-pass filter output terminal via line connects A/D converter, CPU and GSM signal projector successively.Id signal source comprises: input end connects the transformer T of ac cable live wire and zero line, the output terminal of transformer T connects first and the 3rd binding post of diode rectifier bridge, second binding post warp of diode rectifier bridge and the 4th binding post are connected to the input end of squegger, and the output terminal of squegger is connected to signal receiver through the second electric capacity C2.Diode rectifier bridge second and the 4th binding post connect circuit between be connected with the first electric capacity C1.The power input in id signal source is provided with air switch.Relay is electromagnetic type relay.Alternating current in ac cable is 220V, 50Hz.
In Fig. 1, central controller sends signal by day, forms loop by relay, can judge that whether cable is intact, after energising in evening, can be identified, send to central controller signal, thus judge that whether cable is intact by signal source.If cable occurs abnormal, then can point out to corresponding responsible official by GSM net by Centralized Controller.Centralized Controller can receive control terminal order by GSM net, and sends public lighting circuit status signal to control terminal, the status signal of anti-theft alarm for cable under street lamp unlatching or off state that public lighting circuit end connects can be detected simultaneously.
Under street lamp opening, electromagnetic type relay KEM coil is added with 220V operating voltage, switch " 3 " closes with " 1 ", id signal source produces a signal specific and is added on road lighting cable, and be transmitted to Centralized Controller, therefore, can judge that whether road lighting cable is intact by Centralized Controller detection with or without signal specific.
When under street lamp closed condition, electromagnetic type relay KEM " 3 " and " 2 " are in normally off, at the end of road lighting cable, the end of public lighting circuit is connected in parallel on after being connected with inductor by a fuse FU, be equivalent to direct-current short circuit state, therefore, detect whether street lamp is that zero Europe resistance judges that whether road lighting cable is intact by Centralized Controller, fuse FU in figure plays a protective role to alarm and public lighting circuit, inductor L be prevent public lighting circuit just opened power up time road lighting cable be not in short-circuit condition, to guarantee the safety conversion of relay status.
As shown in Figure 2, figure discontinuous oscillator produces sinusoidal wave or square wave to id signal source schematic circuit, and its frequency should be greater than 1KHZ, T0 should be 5 ~ 10ms, and in Tm>5min, figure, C2 plays high impedance effect to 50Hz.
In Centralized Controller circuit, the first K switch 1-1 controls by CPU, when street lamp in off position time, first K switch 1-1 is in " 1 " position, CPU starts the direct current resistance of A/D detection line, because line terminal is now be in short-circuit condition, the normal resistance of therefore testing be about zero Europe, otherwise can think that public lighting circuit is stolen or break at certain point, certainly also may there is end warning circuit and have problem.Street lamp in opening time, the first K switch 1-1 is in " 2 " position, and CPU starts A/D converter and detects from the id signal of terminal alarm, if had, then public lighting circuit is normal, otherwise public lighting circuit is abnormal.When public lighting circuit is abnormal, CPU starts GSM signal projector immediately and sends information to Control Room or relevant responsible official.
