Description
Technical field
The utility model relates to safety precaution field, particularly relates to a kind of signal and processes alarm unit.The utility model also relates to by described signal processes a kind of fence that alarm unit forms.
Background technology
At present, in housing unit or other places, base periphery, fence is installed on solid wall has become requisite security link, and fence is generally fixed area burglar alarm service is provided, and two kinds of more common fence forms are:
1. active electronics fence, is not generally provided with entity fence, mainly adopts infrared opposite-type detector or laser correlative detector, and it differentiates whether there is intrusion behavior according to the sudden change on infrared or laser signal.
Active infrared correlative detector and laser correlative detector are usually used in outdoor enclosing wall alarming.In the time that object is crossed its search coverage, interdict infrared beam and cause alarm.Active infrared correlative detector and laser correlative detector will be selected the suitable triggering response time: the response time is too short easily causes unnecessary interference, and as bird flies over, falling leaf is crossed etc. and to be caused false alarm; Oversize easy formation failed to report police.In addition, all may produce wrong report for blocking of the dense fog in nature, sleet, leaf or flowers and plants.
2. passive type fence, mainly by entity fence, tension force or pulse detection installation composition, tension force or pulse detection device are converted into electric signal and whether have intrusion behavior in order to differentiate detecting invasion signal on entity fence;
Pulse electronic fence is usually used in outdoor enclosing wall alarming.In the time that object is crossed its search coverage, cause adjacent wires short circuit or open wires to cause alarm.Pulse electronic fence will be selected suitable trigger pulse amplitude: pulse height is too low easily causes unnecessary interference, and as light rain, little grass waits and causes electric leakage false alarm; Tai Gaozeyi forms and fails to report police.In addition, the electric leakage causing for the dense fog in nature, sleet, leaf or flowers and plants all may produce wrong report.Fly over/falling leaf of the bird that pulse electronic fence has solved active infrared/laser correlative detector is crossed etc. and to be caused false alarm problem, weaken the wrong report problem that the dense fog in nature, sleet, leaf or flowers and plants are caused, but producing again a new problem, is exactly the safety problem that high-voltage pulse easily damages human body.
Tension electronic fence is usually used in outdoor enclosing wall alarming.In the time that object is crossed its search coverage, cause one or more tension cord tension variation to cause alarm.Tension electronic fence will be selected suitable trigger sensitivity: sensitivity is too high easily causes unnecessary interference, and as wind and snow rain, vegetation touches tension cord and causes false alarm; Sensitivity is too low easily to be formed and fails to report police.In addition, the interference causing for the dense fog in nature, sleet, leaf or flowers and plants all may produce wrong report.Tension electronic fence has solved the high-voltage pulse of pulse electronic fence to invader's life safety problem, does not still solve the wrong report problem that dense fog, sleet, leaf or flowers and plants in nature are caused.
Except aforementioned safety problem and wrong report problem, conventional fence all exists enclosure wall part not possess warning function can not realize warning function in the time being destroyed, and the problem that fence is attractive in appearance is installed on enclosure wall.
