Description
Technical field
The utility model relates to alarm fields, specifically, being a kind of anti-theft alarm for cable.
Background technique
Expressway Road monitoring device cable is stolen phenomenon duration and occurs, and after cable is cut, on the one hand causes great
Direct economic loss, on the other hand also influenced the normal operation of road monitoring equipment, the management of traffic safety
It manufactures into and seriously affects.While increasing people's air defense dynamics, using the intelligent anti-theft of power cable, should be solve the problems, such as it is important
Technological means.The author makes a power cable anti-theft alarm device according to Expressway Road monitoring device cable service condition,
It aims at the monitoring of Expressway Road monitoring device cable theft-prevention and designs.
Utility model content
In order to solve the above-mentioned technical problem, the utility model, which is used, is mounted on power distribution room power distribution cabinet for anti-theft device for cable
It is interior, it is connected on road furniture cable by current-voltage transformer, anti-theft alarm for cable is opened when to equipment power transmission, reported
Alert device is on the alert, once outfield electrical equipment is cut or closed to power transmission cable, anti-theft device for cable starts alarm, i.e.,
Alarm condition can not be eliminated by connecting the cable that will be cut again again, and report could be released by only resetting in alarm host machine switch
It is alert, safety guarantee is provided to road cable, and an anti-theft device for cable only need to be installed on every road cable, it is at low cost, it fits
Ying Xingqiang, it is easy for installation.
To achieve the goals above, the specific technical solution that the utility model uses is as follows:
A kind of anti-theft alarm for cable, which is characterized in that mainly include anti theft host, combined aural and visual alarm and monitoring center value
Class's phone three parts composition, the anti theft host are installed in power distribution room power distribution cabinet, are connected to by current-voltage transformer
On pipeline equipment cable, the anti theft host both can also pass through group net operation with independent operating.
The utility model is further improved, and the anti theft host is on the alert when accessing power supply.
The utility model is further improved, and outfield electrical equipment is cut or closed to the anti theft host in power transmission cable,
It can sound an alarm.
The utility model is further improved, and the anti theft host is under alarm state, even if the cable cut is weighed again
Alarm condition can not be eliminated by newly connecting.
The utility model is further improved, and can only switch to reset by alarm host machine under the alarm condition could release report
It is alert.
Anti-theft device for cable is mounted in power distribution room power distribution cabinet the utility model has the beneficial effects that using, passes through electric current
Voltage transformer is connected on road furniture cable, and anti-theft alarm for cable is opened when to equipment power transmission, and alarm is in police
Ring state, once outfield electrical equipment is cut or closed to power transmission cable, anti-theft device for cable starts alarm, even if will be cut
Cable connect again can not eliminate alarm condition again, only resetting in alarm host machine switch could release alarm, to road
Cable provides safety guarantee, and only need to install an anti-theft device for cable on every road cable, at low cost, adaptable, peace
Dress is convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structure principle chart of the utility model.
In figure, 1- anti theft host, 2- power distribution cabinet, 3- combined aural and visual alarm, 4- monitoring center working telephone.
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is done below in conjunction with embodiment and is further retouched in detail
It states, which is only used for explaining the utility model, does not constitute and limits to the protection scope of the utility model.
A kind of embodiment: anti-theft alarm for cable, which is characterized in that mainly include anti theft host 1, combined aural and visual alarm 3 and
4 three parts of monitoring center working telephone composition, the anti theft host 1 is installed in power distribution room power distribution cabinet 2, mutual by Current Voltage
Sensor is connected on road furniture cable, and the anti theft host 1 both can also pass through group net operation with independent operating.
In the present embodiment, alternating voltage is incuded from mutual inductor T, is mentioned after C1 rectifying and wave-filtering by the pole b that R1 is BG1
Voltage supplied, relay J1 conducting.Under the state of alert, the pole BG2b bias voltage is through relay switch shorted to earth, BG2 not work
Make.Such as robber's feelings, relay switch is disconnected, BG2 work once electrified immediately.BG2 emitter current is led through R3 triggering SCR
Logical, indicator light LED is bright, exports alarm control signal through BG2J2 and issues alarm sound to alarm buzzer, even if at this moment
It is that disconnection cable is reclosed, is not also missed according to report, alarm could be released by only turning off the power switch, so having tamper-proof work
With.
In the present embodiment, anti theft host 1 is on the alert when accessing power supply.
In the present embodiment, outfield electrical equipment is cut or closed to anti theft host 1 in power transmission cable, can be sounded an alarm.
In the present embodiment, anti theft host 1 is under alarm state, even if the cable cut is connected again again to disappear
Except alarm condition.
In the present embodiment, can only switch to reset by alarm host machine under alarm condition could release alarm.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this
The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change
And improvement, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope
It is defined by the appending claims and its equivalent thereof.
