Abstract
The utility model relates to a cable anti-theft alarm device which is provided with a power feeder, a host and a terminal. The terminal can detect phenomena of power lines such as open circuit, short circuit, and phase absence, and feedback the detected information to the host through power feeder carrier, thereby time, location, harassment level and property can be accurately alarmed. The carrier signal transmission between the host and the terminal uses frequency-hopping voice pulse modulation, which is anti-interference, safe and reliable. The host can serially communicate with the computer, transfer the alarm information to the monitoring center and preset-numbered mobile phone through telephone network, and distinguish whether the detector itself is damaged.
Description
Affiliated technical field
The utility model relates to a kind of cable anti-theft alarm device.
Background technology
Be laid on power supply facilitiess such as open-air electric wire, cable, transformer, cut stolen incident to happen occasionally, bring for industrial and agricultural production and people's lives and have a strong impact on, how to protect electric wire, cable and power supply facilities to seem very important.Burglar alarm is of a great variety in the market, reveal cable intrusion detector etc. as two-beam or multi beam active infrared line intrusion detector, microwave wall formula intrusion detector, pulsed high-voltage fence and microwave, these anti-theft devices all have a common fault, as long as in the stage of deploying troops on garrison duty, no matter be the offender, all can report to the police as long as enter the cloth defence area,, also can produce the wrong report that animal is brought out if highly sensitive.And two-beam or multi beam active infrared line intrusion detector and microwave wall formula intrusion detector only be applicable to the open-air atmosphere of being convenient to safeguard, in the open air because the complicated easily wrong report of environmental factor and damaging; Adopt microwave to reveal the cable intrusion detector mode, leaky cable is imbedded underground, come the changes of magnetic field in the very low range around the detection streamer by desensitization, Hang Zou people does not just have wrong report so on the ground, protect cable by this way, lay a pair of leaky cable simultaneously with cable, cost is higher, for completed works, can't transform; The anti-theft effect of pulsed high-voltage fence is better, place a circle high pressure iron silk screen in controlled highway section, send into thousands of volt high voltages by pulsed high-voltage generator, can shock by electricity the guilty party when the people touches net, because effluve, line voltage descends rapidly, at this moment alarm will be reported to the police, but it is unrealistic first to wrap up in one deck high-voltage fence outside cable, second can produce alternating magnetic fields, may can't pass by EMC then.Therefore these burglar alarms all are not suitable for and are laid on the antitheft of open-air power supply facilitiess such as electric wire, cable and transformer.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of open-air antitheft cable anti-theft alarm devices of power supply facilities such as electric wire, cable and transformer that are used to be laid on.
