Embodiment
The present invention is described further below in conjunction with accompanying drawing.
Structural representation of the present invention as shown in Figure 1, form base station end signal collecting device according to three-phase voltage sensor, three-phase alternating current outage monitor and base station power and environmental monitor, wherein the three-phase voltage sensor is connected with electric power facilities of base station with three-phase alternating current outage monitor.Base station power and environmental monitor adopt one of applicant the number of patenting be the system of 200420094647.7 utility model patent.
Concrete networking mode of the present invention as shown in Figure 2, the back-stage management center comprises server and operating terminal, and signal collecting device is arranged on and concrete is powered on the base station by power supply station, adopts the existing delivery platform of base station such as note, GPRS, 2M etc. to transmit networks signal collecting device is connected with the back-stage management central site network.
Three-phase voltage sensor among the present invention adopts AC voltage sensor, the electric power system that offers the base station according to electrical network is gathered the voltage of three-phase electricity, phase voltage as three-phase electricity under the situation of normal power supply is 220V (actual measured value can be unsteady to some extent), when wherein one or more the situation of broken string occurs, base station power and environmental monitor send to the back-stage management center with the information of voltage that collects in time by the data transport network of base station, and the phase voltage abnormal conditions are learnt at the back-stage management center.
The electric voltage exception situation comprises:
Three-phase voltage disappears simultaneously and has ground wire in the three-phase and four-line to be cut off or exchange the situation of power failure;
In the three-phase electricity all there be not three-phase voltage, and signal collecting device is sent to the data at back-stage management center for disconnect by stages, 10 seconds (can set interval time according to actual conditions) second phase voltages just do not disappear to having behind the voltage at interval as first phase acquisition, again at interval after 10 seconds third phase voltage also disappear, can tentatively be judged as transformer in the case or stolen situation appears in cable.
Three-phase alternating current outage monitor among the present invention is a duty of judging transformer or cable by the line voltage that exchanges three-phase.The phase line voltage of three-phase electricity is 380V (actual measured value can be unsteady to some extent) in the time of normal, when three-phase electricity power supply three-phase alternating current outage just often monitor is output as low level, in three-phase occurring, be output as the threshold level that between high-low level, is worth under the situation of one tunnel outage, under the situation that three-phase electricity is all cut off the power supply, be output as high level.Base station power and environmental monitor can judge according to three-phase alternating current outage monitor output level whether three-phase wire voltage is normal.
The present invention forms base station end transformer or cable working state monitoring with three-phase voltage sensor and three-phase alternating current outage monitor with base station power and environmental monitor, and monitoring state is as follows:
1, stolen when zero line occurring, three-phase alternating current outage this moment monitor is with nowhere to turn to the police, three-phase voltage sensor three-phase voltage is all unusual, and base station power and environmental monitor will be sent the back-stage management center on the collection result, the back-stage management center according on send the result can judge that zero line occur to steal feelings;
2, when stolen phenomenon appears in a live wire, alarm appears in three-phase alternating current outage this moment monitor, three-phase voltage sensor acquisition voltage single channel occurs unusual, base station power and environmental monitor will be sent the back-stage management center on the collection result, the back-stage management center according on to send the result can judge that live wire occurs stolen;
3, when theft phenomenon that being disconnected successively appears in three-phase firewire, three-phase alternating current outage this moment monitor alarm all can occur when detecting under the situation that to cut off appear in any one road live wire, the three-phase voltage sensor acquisition occurs (being cut off at last as zero line) unusually to three road voltages successively, the back-stage management center judges it is artificial trimming or power failure naturally according to the time interval that alarm for power-off appears in the interchange three-phase, promptly be judged as power failure than weak point as 1 second as the interval, otherwise be the theft that three-phase firewire is disconnected successively;
4, the theft phenomenon that disconnects simultaneously when three-phase and four-line, alarm appears in three-phase alternating current outage this moment monitor, three-phase voltage sensor acquisition voltage occurs unusual, the phenomenon that occur this moment is the same with AC dump, the back-stage management center can be according to the information of base station power and environmental monitor, gather associated base station (same ac power supply line is used in several base stations) simultaneously, similar warning information also occurs as association base station and then be judged as the electric power system outage, otherwise be the theft that three-phase and four-line disconnects simultaneously.
The present invention has overcome in traditional transformer or the cable theft-prevention and has judged the existing very big drawback of robber's feelings according to the voltage of three-phase electricity, conventional art when the three-phase voltage collector in the power supply process of phase three-wire three if the result who detects under the stolen situation of zero line for having a power failure, and the present invention can mainly be divided into above-mentioned 4 kinds as the case may be and steals mutual affections and analyse, and obtains the stolen situation of electric power facility more comprehensively.
The three-phase voltage sensor adopts the interchange 1:1 isolating transformer of high-isolation among the present invention, and use high-precision rectifier system to guarantee the acquisition precision and the stability of AC voltage sensor effectively, three-phase alternating current outage monitor among the present invention adopts the interchange 1:1 isolating transformer of high-isolation equally, and realizes ternary output according to input three-phase voltage state.
