Abstract
The utility model provides an anti-theft monitoring system for a transformer, which comprises an optical fiber, an optical fiber detection module, a communication module and a monitoring mainframe. The optical fiber is wound on the transformer to protect the transformer and completes the self-loop of a light path via the optical fiber detection module which is connected with the communication module for detecting the on/off status of the transmission and reception of an optical signal and transmitting the information to the communication module. The monitoring frame receives the warning information transmitted from the communication module and displaying the warning information to the personnel while recording the alarm in a historical database. By adopting the light path self-loop of the optical fiber, the monitoring system provides an effective and reliable monitoring manner for the transformer, and also prevents the interference of external objects. The optical fiber is made from non-conductive materials and can prevent the thunderstroke phenomenon caused by an attached power supply; therefore, the monitoring is safer and more reliable.
Description
One, affiliated technical field
The utility model relates to a kind of transformer anti-theft supervisory system, relates in particular to the long-range anti-theft monitoring system of the transformer of communication base station in the communications field.
Two, background technology
In the communications field, there is dotted communication base station, the base station is installed in more remote mountain top or mansion roof mostly, and condition is arduous, often adopts unattended mode; Along with skyrocketing of international copper valency, the outdoor transformer in base station has become lawless person's pilferage object, and they steal a large amount of copper core in transformer the inside, sell off channel etc. by waste product obtains illegal profit.This behavior has destroyed the power supply of communication line, causes communication disruption, causes heavy economic losses to common carrier, and people's life also is subjected to very big influence.
Therefore for the transformer of communication base station, all take certain anti-theft measure usually, for the transformer anti-theft supervisory system, the existing common step of method is:
Gather voltage by voltage sensor, infrared, shock sensor is gathered ambient signal and is input to Single Chip Microcomputer (SCM) system
Single Chip Microcomputer (SCM) system is low or have infrared or vibration signal is judged antitheft alarm signal according to voltage;
Single Chip Microcomputer (SCM) system is local preserve alarm signal, simultaneously with alarm signal by delivering to center host on the communication network.
Center host shows and preserves and alarm.
There is following shortcoming in this technical scheme: the one, and easy wrong report when normally having a power failure, can cause the voltage sensor erroneous judgement; Animal (as poultry) occurs around the transformer, during objects such as automobile, can cause erroneous judgement infrared, shock sensor; The 2nd, sensor is installed on outdoor, rainwater, and rugged surroundings such as high temperature have strengthened the failure rate of sensor; The 3rd, the base station equipment potential safety hazard, the sensor all needs indoorly from the base station to draw power supply power supply, and these power leads are drawn out to outdoor, cause lightning strike accident easily, damage outdoor sensor.Simultaneously, the thunderbolt heavy current flows to valuable equipments such as the indoor integrated drive generator in base station, base station controller by power lead, causes bigger communication accident and economic loss.
Three, utility model content
Based on this, the purpose of this utility model is to propose a kind of long-range transformer anti-theft supervisory system, this supervisory system utilizes optical fiber to carry out signal transmission, overcomes wrong report of the prior art, sensor fault rate height and base station equipment problems such as safety is latent such as be struck by lightning easily.
The utility model is achieved in that
A kind of transformer anti-theft supervisory system; it includes optical fiber, fiber detection module, communication module and monitoring host computer, and optical fiber is wound on the transformer, and transformer is protected; and finish light path by fiber detection module and encircle certainly; fiber detection module is connected with communication module, the break-make situation of sensed light signal transmitting-receiving, and these information are sent to communication module; monitoring host computer; the warning message that send on the received communication module, and present to the staff, simultaneously alarm is recorded in the historical data base.
Transformer, because it is installed on remote location mostly, unmanned is a monitored object of the present utility model.The utility model adopts optical fiber to protect; optical fiber must be cut off during theft and transformer could be stolen; the light path of optical fiber provides monitor mode effectively reliably from ring for transformer control; simultaneously; also can avoid the interference of external object, and optical fiber is non-conducting material; can avoid setting up the thunder-strike phenomenon that power supply brings, make monitoring safer reliable.
Described optical fiber comprises soft fiber and hard optical fiber, and soft fiber is the bend-insensitive soft fiber, finishes transformer and twines, and is connected with the waterproof interconnecting device.Because optical fiber is softer, can twine protective transformer from all angles like a cork, guarantee that the robber must disconnect the lid that optical fiber just can be opened transformer; Hard optical fiber is connected with fiber detection module, and the Transmission Fibers signal is connected by interconnecting device between soft fiber and the hard optical fiber.
Described interconnecting device is the waterproof interconnecting device, places near transformer, finishes soft fiber and hard optical fiber linking.Because soft fiber is wrapped on the transformer, therefore, the waterproof interconnecting device that optical fiber is set is convenient to the maintenance of transformer, and the maintainer only need open this waterproof interconnecting device and just can pull down soft fiber transformer is safeguarded.
Hard optical fiber stretching resistance is good, is fit to the connection between the indoor and outdoors of base station, and the steel core of hard optical cable needs reliable the access in the protection zone network.
Described optical fiber burn out detection module, finish light path from ring by soft fiber and hard optical fiber, the break-make situation of monitoring optical signal transceiver, and these information are sent to communication module by intelligent serial ports, in case alarm produces, optical cable burn out detection module is preserved alarm status, and the operator on duty confirms alarm, if light path is connected, alarm status is just eliminated.
Described communication module connects optical fiber burn out detection module and transmission network, finishes intelligent serial ports to the wireless access that waits communication mode of E1/UART/IP/.
Described is center host, by the wireless access that waits network of E1/UART/IP/, and the warning message that send on the received communication module, and present to the staff, simultaneously alarm is recorded in the historical data base.
Adopt method and apparatus described in the utility model, compared with prior art:
Compare with existing transformer anti-theft supervisory system, the antitheft scheme of transformer optical fiber has following advantage:
The accuracy height.In case optical fiber is cut off, optical signal transmission is interrupted, and just warning information can be transferred to the operator on duty of Surveillance center and locate in very short time, can not be had a power failure and interference that animal is moved.
Security is good.Outdoor no sensor has been avoided the high problem of sensor fault rate; What inside of optical fibre transmitted is light signal rather than traditional electric signal, and transformer side does not need the extra work power supply, only connects by optical fiber inside and outside the base station, the lightning current of outside, base station can be incorporated into inside of base station.
