The utility model provides a passive wireless infrared alarming device which consists of a signal detecting circuit, a wireless transmission circuit, a wireless receiving circuit and an alarming circuit, wherein the signal detecting circuit is connected with the wireless transmission circuit, and the wireless receiving circuit is connected with the alarming circuit. The passive wireless infrared alarming device has the benefits that 1) a wireless data transmission manner is adopted, therefore, rewiring is not needed, and the device is particularly suitable for users whose house is decorated and occasions that are not convenient for wiring, 2) the device has wide monitoring range, far detecting distance and high reliability, and 3) the device is low in cost and simple in structure.
Description
Technical field
The utility model relates to a kind of warning device, specifically, relates to a kind of passive type Radio infrared warning device, belongs to the alarm technique field.
Background technology
Along with the continuous progress in epoch, entity and individual have higher requirement to own environmentAL safety of living in, thereby anti-theft measure has been proposed new requirement.Intelligent alarm system has all been installed in now a lot of places, has improved safe coefficient greatly, has effectively guaranteed resident's personal safety as well as the property safety.
Burglar alarm is with a long history, and is of a great variety, as Ultrasonic Intruder Alarm, and touch time-delay anti-theft alarming device, touch burglar alarm etc.The video monitoring automatic alarm system has all been installed in some banks, market and hotel.This system works is got up effectively reliable, but cost height, unhidden is difficult for popularizing at average family and office.
Along with the continuous development of science and technology, the infrared emanation technology obtains application more and more widely in burglar alarm.Infrared alarm is to utilize infrared technology to come the technology that the invador is surveyed, and can be divided into active and passive infrared and report to the police two kinds.The active infrared alarm is made up of infrared emission and receiver two parts.Transmitter and receiver is installed in the two ends in zone relatively, and infrared transmitter sends a branch of modulated infrared beam and is received the machine reception, forms an invisible warning line of being made up of infrared beam.When the people invaded warning line, infrared beam is partly obtained all to be blocked, and the infrared signal that receiver is received is suddenlyd change, thereby sends the warning trigger pip.Outwards do not launch any energy during the passive infrared alarm work, only be abutted against receipts nature energy or energy variation and finish the detection purpose.When the people enters anti-norm space, can cause the variation of infrared energy, infrared sensor becomes corresponding electric signal to the variation of this energy, through suitably processing, can send alerting signal.The infrared eye that adopts pyroelectric infrared sensor to constitute has that structure is small and exquisite, advantages such as reliable operation, stable performance and cheap in price, has a extensive future.In the traditional optical acquisition system, install the electron device of data processing additional, can realize digitizing, the robotization of measuring.
Usually adopt the cable data transmission mode at present, concerning the occasion of renovated user and wiring inconvenience, need rewiring, use very inconvenient.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of passive type Radio infrared warning device is provided.
In the passive type Radio infrared warning device of the present utility model, said device is made up of signal deteching circuit, radio transmitter, wireless receiving circuit and warning circuit; Wherein said signal deteching circuit links to each other with radio transmitter, and said wireless receiving circuit links to each other with warning circuit.
Preferably,
Said signal deteching circuit is made up of pyroelectric infrared sensor P2288 and BISS0001 signal processing circuit.
Said radio transmitter and wireless receiving circuit all adopt the nRF401 wireless chip.
The principle of work of passive type infrared radio alarm of the present utility model is: pyroelectric infrared sensor, infrared special chip and peripheral circuit thereof, detect the infrared ray of human body radiation with the noncontact form, be translated into and relevant low frequency electric signal such as human motion speed, distance, direction, a warp level state controller later can produce corresponding output signal, thereby reaches the purpose of surveying moving target.Simultaneously, it can also identify the biology of motion and other are abiotic.When infrared sensor has detected human body when invasion, radio transmitter is the geocoding of this detection signal, and is transmitted into wireless receiving circuit, finishes warning by warning circuit at last.
Passive type Radio infrared warning device of the present utility model has following technique effect:
1) the utility model adopts the wireless data transmission mode, does not need rewiring, is specially adapted to renovated user and the inconvenient occasion of wiring;
2) monitoring range is wide, detection range is far away, reliability is high;
3) cheap, simple in structure.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is a signal deteching circuit of the present utility model;
Fig. 3 is a wireless transmission circuit of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail by embodiment.
As shown in Figure 1, passive type Radio infrared warning device of the present utility model is made up of signal deteching circuit, radio transmitter, wireless receiving circuit and warning circuit; Wherein signal deteching circuit links to each other with radio transmitter, and wireless receiving circuit links to each other with warning circuit.Radio transmitter and wireless receiving circuit are by wireless radiofrequency mode Data transmission.
As shown in Figure 2, signal deteching circuit is made up of pyroelectric infrared sensor P2288 and BISS0001 signal processing circuit.BISS0001 is a high performance passive pyroelectric infrared ray sensing signal processor.It is equipped with the rpyroelectric infrared switch of pyroelectric infrared sensor and a small amount of outward element formation passive type.BISS0001 adopts the manufacturing of high-performance CMOS technology, and power consumption is very low; Operating voltage is 3～6V, recommends to use 5V; When operating voltage was 5V, the drive current of output corresponded to 10mA; Working temperature is-20～70 ℃; Storage temperature-40～125 ℃.BISS0001 mixes special IC by the digital-to-analogue that operational amplifier, voltage comparator, state controller, time delay, timer and blocking time timer etc. constituted.After P2288 detected human body radiation, its S utmost point was exported detectable signal voltage, and import among the BISS0001 by 14 pin and amplify, and by 2 pin output control signal.
As shown in Figure 3, radio transmitter adopts identical nRF401 wireless chip with wireless receiving circuit.NRF401 promptly can also can be used as receiving circuit as radiating circuit.When TXEN=1, it is a radiating circuit.Otherwise when TXEN=0, it is a receiving circuit.When having key to press, IC2 receives the low level of input, and IC1 receives the high level of input, makes NRF401 enter emission state.When no key was pressed, IC2 sent low level, made it to enter accepting state.By transceiver circuit, signal is amplified, the signal carrier frequency is removed in demodulation.By the output of 10 pins, be input to warning circuit at last.
Warning circuit adopts the SPY0030 power amplifier that sound signal is amplified, and drives loudspeaker, finishes speech play.It can be operated in the 2.4-6.0V scope, and peak power output can reach 700mW.
The above only is a preferable embodiment of the present utility model, not in order to restriction the utility model, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
