Abstract
The utility model discloses a terminal signal feedback ware of cable electronic monitoring, the terminal feedback ware of cable theftproof is installed on the street lamp cable, including dc circuit and ac circuit, dc circuit includes thermistor, is equipped with positive and negative wiring end, and anodal wiring end forms the direct current route with negative terminal after concatenating thermistor, ac circuit includes resistance, electric capacity and diode. The direct current route is pressed at street lamp non -working time section input low -voltage direct current can feed back great detected signal, ac circuit is used for keeping apart the alternating current and to dc circuit's influence, especially street lamp operating time section, forms the protection to thermistor. The utility model discloses small, with low costs, the terminal feedback ware of cable theftproof through the low -power consumption reaches the cable theftproof of street lamp non -working time section, and the terminal feedback ware operating voltage of cable theftproof be direct current 12V, and is out of work in street lamp good time section, and the low power dissipation is energy -concerving and environment -protective, is provided with corresponding protection circuit, and not fragile, cost of maintenance hangs down.
Description
Technical field
The utility model relates to lighting control technique field, particularly a kind of cable theft prevention monitoring end signal feedback device.
Background technology
Along with the development of city China urbanization, city construction project constantly increases, scale constantly increases, some construction projects improve constantly for the requirement of energy resource consumption and intelligent control management, particularly, at city street lamp lighting field, will save electric power energy consumption and intelligent control management is important indicator. And in existing open urban illuminator, generally to adopt by the control model of period switch, such control model has many shortcomings, for example, no matter whether need out (pass) lamp, open (pass) lamp time as long as arrive, lamp also can be opened (or closing), can not open according to longitude and latitude adjustment the time of (pass) lamp, the area that longitude and latitude is different, sunset time is also different, and after turning on light, no matter the stream of people mostly is few, be all that the lamp of whole quantity is being worked; Once have a power failure, whole system all cannot be worked; And entire system monitoring of tools deficiency, for fault and artificially steal the monitoring alarm deficient function of equipment, break down and be difficult for clear failure equipment place position, intelligent degree is low, be not easy to repair and maintenance, cable theft prevention monitoring end-equipment for public lighting circuit is all larger, and the large energy consumption of power is high, fragile.
Summary of the invention
The utility model is large for current urban lighting system circuit cable theft prevention monitoring end-equipment, and the large energy consumption of power is high, and the fragile deficiency that waits provides a kind of cable theft prevention monitoring end signal feedback device. The technical solution of the utility model is:
A kind of cable theft prevention monitoring end signal feedback device, described cable theft prevention end ultramagnifier is arranged on street lamp cable, comprises DC circuit and alternating current circuit; DC circuit comprises thermistor, is provided with positive and negative terminals, after positive terminal serial connection thermistor, forms DC channel with negative terminals; Alternating current circuit comprises resistance, electric capacity and diode. DC channel can feed back larger detection signal at street lamp non-working time section input low-voltage dc voltage; Alternating current circuit, for isolating the impact of alternating current on DC circuit, particularly street lamp working time section, forms protection to thermistor, increases the service life of thermistor.
As the preferred technical scheme of the utility model, also comprise the relay that disconnects thermistor DC channel while connecting alternating current.
Closer, described thermistor is semistor.
Closer, described alternating current routing resistance and connect after be connected with described relay through a rectifier bridge, between rectifier bridge and relay and be connected to electric capacity and diode.
Closer, under described semistor normal temperature, resistance is 10 Ω-20 Ω.
Advantage of the present utility model:
The utility model volume is little; cost is low; reach the cable theft prevention of street lamp non-working time section by the cable theft prevention end ultramagnifier of low-power consumption; cable theft prevention end ultramagnifier operating voltage is direct current 12V, does not work in street lamp section normal working hours, low in energy consumption; energy-conserving and environment-protective; be provided with corresponding holding circuit, not fragile, maintenance cost is low.

Detailed description of the invention
Embodiment:
A kind of cable theft prevention monitoring end signal feedback device, cable theft prevention end ultramagnifier is arranged on street lamp cable, comprises DC circuit and alternating current circuit; DC circuit comprises thermistor, is provided with positive and negative terminals, after positive terminal serial connection thermistor, forms DC channel with negative terminals; Alternating current circuit comprises resistance, electric capacity and diode. DC channel can feed back larger detection signal at street lamp non-working time section input low-voltage dc voltage; Alternating current circuit, for isolating the impact of alternating current on DC circuit, particularly street lamp working time section, forms protection to thermistor; Also be provided with the relay that disconnects thermistor DC channel while connecting alternating current; Described thermistor is semistor, and under normal temperature, resistance is 10 Ω; Alternating current routing resistance and connect after be connected with described relay through a rectifier bridge, between rectifier bridge and relay and be connected to electric capacity and diode.
The utility model is by sending the voltage signal of 12V to cable theft prevention end ultramagnifier, judge that according to the feedback signal of cable theft prevention end ultramagnifier whether street lamp cable is stolen, determination methods is in street lamp working time section and non-working time section and different, the 12V direct current sending in street lamp working time section is specifically connected antitheft end ultramagnifier, thermistor resistance is very little, the current signal of feedback is larger, monitoring system judges that according to this signal street lamp cable is in normal condition, if now the current signal of feedback is very little or do not have, judge that street lamp cable is in abnormality, likely stolen. in street lamp working time section, monitor by street lamp cable curent change, be under normal operating conditions, monitoring cable line current, unchanged or amplitude of variation is less judges fault-free or normal fault, if current break amplitude is more greatly, judge that cable is stolen, detect data variation according to branch current and can tentatively judge stolen circuit.
