Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to infrared monitoring warning device embodiment, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
Referring to Fig. 1-2, a kind of infrared monitoring warning device, comprise infrared eye 1, infrared eye 22, wireless receiving system and warning system 11, wherein: wireless receiving system comprises relay 1, relay 24, Sheffer stroke gate logical circuit 7, relay 1 is connected with trigger 1, the output terminal of trigger 1 connects respectively the input end of timer 1 and Sheffer stroke gate logical circuit 7, relay 24 is connected with trigger 28, the output terminal of trigger 28 connects respectively the input end of timer 29 and Sheffer stroke gate logical circuit 7, and timer 29 connects the input end of Sheffer stroke gate logical circuit 7 by clamping circuit 10; The output terminal of Sheffer stroke gate logical circuit 7 connects warning system 11.
Described infrared sensor 12 is burnt electric type infrared ray sensor.
Principle of work: device is installed configuration and is shown as described in Figure 3, with infrared eye 1 and infrared eye 2 combinations, window 14 or other zone of monitoring is formed the infrared ray barrier that crosses together.Known behind human body signal by electric type infrared ray sensor 4 inspections of Jiao, the voltage of a Vdd-0.5V of output, (Vdd=5V) by making amplifier T saturation conduction after resistance R 1, resistance R 2 dividing potential drops, connect the current supply circuit of remote control coding wireless launcher 13, with these remote control coding wireless launcher 13 switches short circuit in advance.After the energising, remote control coding wireless launcher 13 is in the emission duty, and constantly sends signal to wireless receiving system.The relay of receiver is constantly connected, inputted one by one+the 5V high level to circuit, make circuit according to the signal sequence of receiving, through logical operation, make different output.
Deploy troops on garrison duty behind the button pressing apparatus remote control, device is in the state of deploying troops on garrison duty, and wireless receiving system does not receive signal this moment, and the internal digital circuit is in initial holding state.When the outside had the people to move in the monitored area of infrared eye 1, infrared eye 1 transmitted signals to the relay 1 of wireless receiving system.Relay 1 is connected, make+the 5V signal is input in next step the digital circuit, under the effect of high level rising edge, trigger one 5 upset driving timing devices 1 enter definition status and delay time a period of time (5-30 is adjustable second), wait in the delay time whether infrared eye 22 transmits signal, after the people of outside left the monitored area of infrared eye 1, device automatically restored to original state later at delay time.After the people of outside enters into the monitored area of infrared eye 1, do not leave and enter into again in the monitored area of infrared eye 22.At this moment trigger 1 formerly receive infrared eye 1 send signal after, and in timer one 6 delay times, the signal of infrared eye 22 is connected relay 24, trigger 28 upsets, at this moment, trigger 1, trigger 28 are all exported high level, after 7 logical conversions of Sheffer stroke gate logical circuit, make output terminal keep high level output, connect warning system 11 control power supplys, device is reported to the police.
Another kind of situation: when the human motion of inside, be introduced into the monitored area of infrared eye 22, and be not that (according to Environmental adjustments) removed in the monitored area that arrives first infrared eye 1.So relay 24 always receives first the signal of infrared eye 22.Relay 24 is connected, and makes trigger 28 upsets, and control timer 29 enters definition status, and timing was adjustable at 2-5 minute.In timing, the output terminal of Sheffer stroke gate logical circuit 7 by clamping circuit 10 clampers in low level.So no matter after this signal of infrared eye 1 arrives how many times, the equal no-output of the output terminal of Sheffer stroke gate logical circuit 7 can't be connected the circuit of warning system 11, and device is not reported to the police.
As preferably, the assemble method of infrared eye is in the utility model: select two interior pipe 15(material metals or plastics all can), a pipe 15 of installation infrared detector 1 is reamed part by front end one side shown in Figure 4, infrared eye one 1 parts are exposed in the mouth of pipe of truncated section, the tested angle to the inside one side is reduced in the convenient zone of detecting near monitored area one side.Also be so to infrared eye 22, by adjusting infrared eye 22 apart from the position of the mouth of pipe, the tested angle that infrared eye 22 is reduced the inside one side.Two sensors are carried out the adjustment of detection position, height and angle by Fig. 3, monitored zone is formed together by the three dimensions of infrared ray intersection sealing.The region height that suitable adjustment is monitored can be avoided toy oppositely to pass through timer and report to the police, and underwriter or other large objects can't enter again.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
