Description
Technical field
The utility model relates to a kind of safety-protection system, especially a kind of circumference safety-protection system.
Background technology
The circumference safety-protection system that traditional circumference safety-protection system generally has fence and infrared beam interruption detector to constitute.
The electronic fence periphery safety-protection system generally has two kinds: Pulse Electric pressure type and induction.
With reference to figure 1, Pulse Electric pressure type circumference safety-protection system is made up of fence controller 1 to fence controller N and N road bus system or switching value alarm host machine, signal bus or switching value alerting signal line.It is that F, output crest voltage are the pulse voltage output terminal OUT of U that fence controller has frequency
1, OUT
2, with pulse voltage loop input end IN
1, IN
2, connect and compose the loop by metal bare wire line 1, line 2, line 3, the line 4 of four parallel installations on Fig. 1 and the enclosure wall; Touch, bore line 1, line 2, line 3, line 4 more in case have by force, cause the adjacent wires short circuit or cut off line 1, line 2, line 3, line, corresponding fence controller is output bus system or switching value alerting signal just, this signal transfers to N road bus system or switching value alarm host machine through signal bus or switching value alerting signal line, send alert news by it, finish the warning task.
With reference to figure 2, induction circumference safety-protection system is made up of fence controller 1 to fence controller N and N road bus system or switching value alarm host machine, signal bus or switching value alerting signal line.It is frequency electromagnetic waves OUT1, OUT2, OUT3, the OUT4 lead-out terminal of f that fence controller has output frequency, press Fig. 2 respectively with enclosure wall on the metal bare wire line 1, line 2, line 3, line 4 of four parallel installations connect.Line 1, line 2, line 3, line 4 are equivalent to inductance, electric capacity, and its distributed inductance, capacitance parameter are L
0, C
0In case, there is the people to touch, bore more or causes the adjacent wires short-circuit conditions to take place, will cause its distributed inductance, capacitance parameter L
0, C
0Change, this variable quantity makes corresponding fence controller output frequency f change, according to this variable quantity, fence controller is output bus system or switching value alerting signal just, this signal transfers to N road bus system or switching value alarm host machine through signal bus or switching value alerting signal line, send alert news by it, finish the warning task.
With reference to figure 3, infrared beam interruption detector circumference safety-protection system is made up of infrared beam interruption detector 1 to N and N road bus system or switching value alarm host machine, signal bus or switching value alerting signal line.Infrared beam interruption detector is a kind of detector that is widely used in the circumference security system, and it normally is made up of an infrared transmitter and an infrared receiving set.Its basic functional principle is: transmitter sends the infrared signal of a branch of or a few bundle through modulating, receiver is received and is made after this signal demodulation constant or other signals that can represent its current state of one of its output give system host, in case the light beam that transmitter sends is interdicted, receiver loses input signal, bus system or switching value signal that its output expression different with original state reported to the police are given N road bus system or switching value alarm host machine, main frame is made corresponding processing, is sent alert news, realizes warning function.
The defective of legacy system
1) defective of electronic fence periphery warning system is that the electronic fence periphery warning system has more intense " stopping and certain deterrence function ", but can not be divided into too much defence area, construction, installation inconvenience, " scaring " possibility to normal resident is arranged when using high-voltage pulse, and have the risk that causes normal resident to come to harm; If use action of low-voltage pulse, then exist and crack the possibility that makes it to lose efficacy with technological means easily.Induction electronic fence periphery warning system also exists the higher defective of rate of false alarm.In a word, electronic fence periphery warning system " the obstruction function is strong, warning function weak ", cost is higher when constituting many defence areas.
2) defective of infrared beam interruption detector circumference safety-protection system is that infrared beam interruption detector circumference security protection system is opposite with the electronic fence periphery warning system, it does not possess " obstruction " function, but it is disguised better, cost is low, warning function is strong, is the main product in the existing market.But due to its principle, if miscarriage or infrared beam can cause certain wrong report after being blocked by the trees branches and leaves.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of compound circumference safety-protection system traditional triangular web defective, that the operation warning is more reliable and stable, rate of false alarm is lower that overcome will be provided,
In order to solve the problems of the technologies described above circumference safety alarm system of the present utility model, include at least one fence controller and corresponding metal bare wire, fence controller links to each other with bus system or switching value alarm host machine by signal bus or switching value alerting signal line, described system also is provided with at least one pair of infrared beam interruption detector, the electronic fence periphery that described metal bare wire is constituted is divided into some defence areas, and described infrared beam interruption detector links to each other with bus system or switching value alarm host machine by signal bus or switching value alerting signal line.
Described fence controller can be a Pulse Electric pressure type fence controller, Pulse Electric pressure type fence controller is provided with at least one pair of output terminal and input end, output terminal, input end and corresponding metal bare wire are connected, and are interconnected to form the loop with metal bare wire that every pair of output terminal links to each other with input end.
Described fence controller also can be induction fence controller, and the output terminal of induction fence controller is connected with the metal bare wire.
The circumference safety alarm system that the utility model constitutes fence, the compound use of infrared beam interruption detector has just in time overcome the other side's defective mutually, has brought into play strong point separately, makes the circumference safety alarm system be tending towards perfect.Constitute the perimeter system with " obstruction " function by fence on enclosure wall in the use, then several infrared beam interruption detectors are installed on the enclosure wall according to the distance needs, the circumference that fence is constituted is divided into several defence areas.When the metal wire of electronic enclosure system by short circuit, touching, cut off, fence controller just output bus system or switching value alerting signal to system bus system or switching value alarm host machine, this moment, main frame only provided early warning signal, when corresponding infrared beam interruption detector also provides bus system or switching value alerting signal (infrared beam is interdicted), system bus system or switching value alarm host machine are just formally sent alert news (having regarded as illegal invasion), when promptly having only fence and infrared beam interruption detector to send alerting signal simultaneously, system bus system or switching value alarm host machine assert that just illegal invasion is arranged, send alert news, finish the warning task; Vice versa.
Fence of the present utility model can be the pulsating electronic fence, also can be induction fence.
This shows, compound circumference safety alarm system has had the variation of matter than the perimeter alarm system of traditional single type, its reliability, stability have had significantly raising, rate of false alarm reduces greatly, system possessed bigger stop the deterrence function, also possessed perfect warning function, overcome traditional triangular web defective fully, brought into play the legacy system advantage, allowed perimeter system that revolutionary variation has taken place.
