A kind of Radio infrared fence comprehensively monitoring warning systemTechnical field
The invention belongs to enclosure wall safety monitoring technology field, especially a kind of Radio infrared fence comprehensively monitoring warning system.
Background technology
Radio infrared fence is also referred to as infrared railing, it is a kind of alarm of active infrared correlation, transmitting terminal wherein sends a bundle infrared light, receiving end is responsible for reception, it is the mode of low frequencies, time-division detection between this transmitting terminal and receiving end, once have personnel or object to block, any adjacent two bundles that transmitter sends exceed certain hour with glazed thread, receiver is output alarm signal immediately, according to its principle of work, can also multiple use be expanded, be widely used in various fields such as city security protection, community, factory, company, school, warehouses.According to the setting of producer, when toy or wisp block wherein Ray Of Light time, alarm can not output alarm signal, but find in actual use, when the toy such as cat, bird is bonded at the top of a wall, still can trigger alarm, the paper of some larger areas, leaf also can trigger alarms even, cause more misoperation, security personnel needs often to carry out site inspection.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Radio infrared fence comprehensively monitoring warning system jointly being judged whether warning by host computer according to the multi-signal received is provided.
The technical scheme that the present invention takes is:
A kind of Radio infrared fence comprehensively monitoring warning system, comprise enclosure wall, enclosure wall is installed many compositions to the transmitting terminal used and receiving end, it is characterized in that: the multiple piezoelectric pressure indicator of the inner setting-in in enclosure wall upper end between described two adjacent transmitting terminals and receiving end, the output terminal of each piezoelectric pressure indicator connects host computer by mixed-media network modules mixed-media, and the control signal output terminal of this host computer connects the high-speed rotary monopod video camera of enclosure wall side installation.
And, described mixed-media network modules mixed-media comprises A/D change-over circuit and RS485 serial port circuit, the input end of A/D change-over circuit connects the output terminal of piezoelectric pressure indicator, the output terminal of A/D change-over circuit connects the input end of RS485 serial port circuit, and the output terminal of RS485 serial port circuit connects the serial ports of host computer.
And, described mixed-media network modules mixed-media comprises A/D change-over circuit and radio transmitter, the input end of A/D change-over circuit connects the output terminal of piezoelectric pressure indicator, the output terminal of A/D change-over circuit connects the input end of radio transmitter, and the output terminal of radio transmitter connects the wireless receiving circuit that host computer fills.
Another object of the present invention is to provide a kind of disposal route of Radio infrared fence comprehensively monitoring warning system, it is characterized in that: comprise the following steps:
(1) transmitting terminal sends infrared light to receiving end constantly, and piezoelectric pressure indicator detects the pressure value of enclosure wall upper surface constantly;
(2) when receiving end exports block signal, piezoelectric pressure indicator does not detect the pressure value exceeding pre-set threshold value, then host computer display state, but does not report to the police, and host computer drives high-speed rotary monopod video camera to turn to enclosure wall place to make an inspection tour;
When receiving end exports block signal, piezoelectric pressure indicator detects the pressure value exceeding pre-set threshold value, then host computer display state, same to alarm, and host computer drives high-speed rotary monopod video camera to turn to enclosure wall place to make an inspection tour;
(1) and (2) (3) constantly repeat step, complete process.
Advantage of the present invention and good effect are:
In the present invention, the multiple piezoelectric pressure indicator of the inner setting-in in enclosure wall upper end between transmitting terminal and receiving end, the output signal of these piezoelectric pressure indicators and the block signal common transport of infrared light are to host computer, whether reported to the police by the state automatic decision of host computer according to two signals, and drive high-speed rotary monopod video camera to make an inspection tour enclosing wall alarming place and periphery, thus avoid in prior art, the false alarm that kitten, bird, paper etc. cause, reduces the working strength of security personnel.

Embodiment
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A kind of Radio infrared fence comprehensively monitoring warning system, as shown in Figure 1, comprise enclosure wall 2, enclosure wall is installed many compositions to the transmitting terminal 1 used and receiving end 4, innovation of the present invention is: the multiple piezoelectric pressure indicator 3 of the inner setting-in in enclosure wall upper end between described two adjacent transmitting terminals and receiving end, the output terminal of each piezoelectric pressure indicator connects host computer 6 by mixed-media network modules mixed-media 7, and the control signal output terminal of this host computer connects the high-speed rotary monopod video camera 5 of enclosure wall side installation.
In the present embodiment, described mixed-media network modules mixed-media comprises A/D change-over circuit and RS485 serial port circuit, the input end of A/D change-over circuit connects the output terminal of piezoelectric pressure indicator, the output terminal of A/D change-over circuit connects the input end of RS485 serial port circuit, and the output terminal of RS485 serial port circuit connects the serial ports of host computer.
Above-mentioned mixed-media network modules mixed-media can also adopt wireless mode, specifically mixed-media network modules mixed-media comprises A/D change-over circuit and radio transmitter, the input end of A/D change-over circuit connects the output terminal of piezoelectric pressure indicator, the output terminal of A/D change-over circuit connects the input end of radio transmitter, and the output terminal of radio transmitter connects the wireless receiving circuit that host computer fills.
The disposal route of above-mentioned Radio infrared fence comprehensively monitoring warning system comprises the following steps:
(1) transmitting terminal sends infrared light to receiving end constantly, and piezoelectric pressure indicator detects the pressure value of enclosure wall upper surface constantly;
(2) when receiving end exports block signal, piezoelectric pressure indicator does not detect the pressure value exceeding pre-set threshold value, then host computer display state, but does not report to the police, and host computer drives high-speed rotary monopod video camera to turn to enclosure wall place to make an inspection tour;
When receiving end exports block signal, piezoelectric pressure indicator detects the pressure value exceeding pre-set threshold value, then host computer display state, same to alarm, and host computer drives high-speed rotary monopod video camera to turn to enclosure wall place to make an inspection tour;
(1) and (2) (3) constantly repeat step, complete process.
In the present invention, the multiple piezoelectric pressure indicator of the inner setting-in in enclosure wall upper end between transmitting terminal and receiving end, the output signal of these piezoelectric pressure indicators and the block signal common transport of infrared light are to host computer, whether reported to the police by the state automatic decision of host computer according to two signals, and drive high-speed rotary monopod video camera to make an inspection tour enclosing wall alarming place and periphery, thus avoid in prior art, the false alarm that kitten, bird, paper etc. cause, reduces the working strength of security personnel.
