Description
Technical field
The utility model relates to a kind of cable anti-theft alarm system, especially a kind of cable monitor terminal controller.
Background technology
In the society of current high speed development; Traffic problems have become the social concern that receives much concern; The stolen phenomenon of highway power cable is very serious, causes great economic loss on the one hand, the more important thing is the normal operation of the equipment of having a strong impact on; Constitute a threat to for the highway operation safety, highway related management department all prevents that power cable from being stolen by the people and cuts seeking positive mode.
The present situation of highway power cable anti-theft technique, the method that is used for cable theft-prevention generally has following several kinds:
1, professional duty personnel carries out inspection on duty.
Hand over patrol police, road administration and local public security department to step up patrols, wait for, reach the caution purpose for the crime personnel, simultaneously quick response is made in stolen highway section, loss is reduced to minimum in the mode of working at a selected spot in shifts that taked 24 hours in frequent stolen location.This kind mode consumes manpower and materials, because the highway distance is longer, cable is stolen to exist contingency again, so produce little effect.
2, adopt civil engineering technology to reach the antitheft purpose
When cable lays with its direct-burried; Buried, system of laying such as shutoff and construction technology combine, and also can adopt whole the service cable pipeline or local concrete sealed mode simultaneously; The cable shaft well lid also adopts the concrete shutoff, can play good anti-theft effect.This kind mode quantities is bigger, and cost is high, effectively also daily repair and maintenance is being made troubles in the antitheft.
3, scientific and technological antitheft means
Do not influencing under the situation that the highway power cable normally lays; Through technological means such as extra installing cable anti-theft alarm device, warning instrument, watch-dogs; When cable is stolen when cutting; The instrument signalisation relevant personnel that give the alarm in time arrest the offender, effectively play the cable theft-prevention effect.Various ways has appearred in cable anti-theft alarm device on the market at present, though alarm principle has nothing in common with each other, mainly shows as two aspects.The one, the collection of burglar alarm signal, the 2nd, the transmission channel of alerting signal.The acquisition mode of alerting signal mainly contains electric current and voltage detection, electric capacity detection, power line carrier detects is main.
4, leakage current detection method
Adopt to detect the electric leakage mode and monitor, cardinal principle is that the three-phase and four-line cable with a highway section passes mutual inductor simultaneously and detects, and normal value should be an initial electrical leakage, and this is worth basic fixed.Terminal people produces electric leakage for making between its live wire and the ground on this road simultaneously, and then the value of its detection should surpass original initial value.In case, think then that cable is stolen to report to the police immediately so detected value returns to normally.This mode is feasible according to its principle in perfect condition, but a lot of problems are arranged in the practical operation, the main performance as follows:
Detecting initial value is difficult to confirm; Owing to aging circuit or at laying-out is that damage is arranged, and the electric leakage situation of circuit more or less all can exist, and according to weather condition (moist or dry) not electric leakage in the time of also can changing to some extent or install; Of long duration electric leakage taken place; So this particular value be difficult to confirm, the installation initial stage reports to the police morely often, and the result heightens and do not report to the police again when cable is stolen behind the initial value and actual effect differs greatly.If be used for places such as lamp stand power supply, because the highway illumination is to control unlatching at times, also can't report to the police when electroless state cuts off the power supply daytime.It is a potential safety hazard that there is leaky in terminal lamp stand of while, loses more than gain in case security incident takes place.
5, power line carrier detection method
Low-voltage powerline carrier communication is meant and utilizes existing low-voltage network as transmission medium, realizes a kind of technology of data transfer and message exchange.
What the technology of power line carrier was considered is to utilize the good carrier of electric power cable as transmitting signal, simply says, utilizes the line of electric force cable exactly, when transmitting electric power, can transmit weak electric signal again, so just need not to lay signal cable.The power supply of highway is mainly to be supplied with by the power transformer of special use, does not make other purposes, and clutter or interference ratio on the line of electric force are less, so power carrier is a kind of reliable economic again method.
Power line carrier detects and to be used for the basic functional principle that cable theft-prevention cuts and to show as 4 kinds of modes:
When the normal power supply state, main frame has detected electric signal, sends carrier signal simultaneously; If extension set also has electricity, also to receive carrier signal, and send the normal response signal, do not send alerting signal this moment, and line work is normal.
Under normal power down mode, main frame detects the short of electricity signal, changes battery-powered, and transmitting terminal sends carrier signal; Because circuit is under power down mode, it is battery-powered that receiving end also changes, beginning reception carrier signal; If circuit is not disconnected, show that circuit is unobstructed, send out one group of carrier signal at set intervals; If circuit is normal, the normal response signal will be arranged, the alert signal of also not transmitting messages this moment.
Under the normal power supply state, as broken string occurring or being cut, normal power supply is arranged and send carrier signal, receiving end has a power failure changes battery-powered, and extension set is in carrier signal, so can not send the normal response signal, can think power circuit generation aborted at this moment.
According to which the warning extension set that is provided with warning taking place on the way and then can infer the distance of warning place apart from starting point, accurately behind the location, can notify the related management personnel to solve as early as possible.
The limitation that power line carrier detects:
The communication distance of power line carrier receives the restriction of a lot of factors, the obstruct of substation transformer; The strong noise that exists on the line of electric force simultaneously is connected to various power equipments on the line of electric force, resistive, capacitive, perception, and frequent switching powerful, low power various device is arranged, and will bring various noise, and communication distance can be quite short.
Though cable is stolen between turnoff time can detection alarm through power line carrier technology, end generally need install lithium battery additional could accomplish the normal electricity carrier communication through lithium battery power supply between turnoff time.But because the charging and discharging lithium battery life-span is shorter, frequent discharge and recharge the direct battery life that influences, bring a lot of inconvenience for the later maintenance cost and the false-alarm quantity of administrative authority.
