Description
Technical field
This utility model is related to a kind of whether stolen street lamp cable burglary-resisting system of detection street lamp cable.
Background technology
Economic prosperity accelerates the paces of urbanization, while driven urban construction fast-developing, as city image
The Landscape Lighting of window, roadway illumination construction and management have also obtained unprecedented great development.But, with city illumination model
The expanding day for enclosing, the problem of management of city illumination facility just become increasingly to project.More seriously luminaire and
The frequent stolen or damage of light conduits, causes street lamp bright not, and this not only affects the landscape in city and traffic, returns illegal
Molecule crime provides favorable environment, brings a series of public security problem to society.
Common street lamp cable theft prevention adopts following several methods：
1. power carrier theft-proof warning scheme, power carrier scheme is using power carrier spread spectrum, by front and back end
Device signal communicate, if during communicating interrupt, then it is assumed that cable is abnormal and report to the police.2. electric leakage burglar alarm scheme, leaks electricity antitheft
Mainly detected also cross transformer by three-phase and four-line cable, normal value should be a specific initial value.Artificial in end
Make between live wire and ground, to produce electric leakage, such detected value should exceed presets initial normal value, just returns to initially when value is detected
Constant value, then it is assumed that cable produces warning extremely.3. communication apparatus is installed additional in lamp stand end implement the scheme that reports to the police using in lamp stand
End installs communication apparatus additional, is powered by public lighting circuit and carry out communication connection by wireless (radio station) or telephone line with main website
System.Type of alarm also has active and two kinds of passive-type.Active need install battery additional, if last end power-off are thought electricity
Cable is stolen, stands this and reports to the police to main website.And passive-type constantly patrols survey by main website, when multiple choosing survey obstructed (due to power cutoff device without
Method works), then think that cable is stolen.
Above several method respectively has feature, but there is also obvious problem：
1. power carrier theft-proof warning scheme has following limitation, when cable has compared with strong jamming noise signal, or cable
On compensating electric capacity excessive, cause carrier signal to be absorbed, and then have influence on before and after's end communication, cause to report by mistake.Meanwhile, carrier wave side
Case is not suitable for overlength circuit, and cable is slowly aging with the time, and therefore carrier signal also can decline, and easily forms wrong report.
2. the initial normal value of electric leakage burglar alarm scheme is present limitation and cable run, local environment are closely bound up,
Therefore be difficult to determine initial normal value, while because producing electric leakage, there is potential safety hazard, and can not detect under electroless state.
3. the scheme for installing communication apparatus enforcement warning additional in lamp stand end installs communication apparatus additional using in lamp stand end, by road
Lamp driver power by wireless (radio station) or telephone line and main website carry out this mode of communication contact be reliable,
The rate of false alarm that reports to the police is than relatively low, and can be properly positioned according to coded address, but which also has certain limitation：Its
Can only report to the police in the case of circuit has electricity (do not accomplish 24 hours round-the-clock）；Capital and installation difficulty are knocked down in advance all than larger,
Which includes：Street lamp end must all have radio station or telephone wire to tap into, the exercise question that antenna is installed, lightning protection measures etc..
It is therefore desirable to a kind of cable detects cable theft prevention system safe and reliable, convenient for installation and maintenance.
