Brief description of the drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is parts connection diagram of the present utility model.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment is only for the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in Figure 1, long-range household safety alarm system of the present utility model, comprises microprocessor unit 1, infrared eye unit and GSM modulator-demodular unit;
Infrared eye unit comprises that the signal that passive type infrared eye 21, signal conditioning circuit I21 and analog to digital conversion circuit 23 passive type infrared eyes 21 survey processes through signal conditioning circuit I22, and after analog to digital conversion circuit 23 conversions, exports the signal input part of microprocessor unit to; Passive type infrared eye does not need additional infra red radiation light source, and itself does not launch any energy to the external world, but by detector direct detection the infrared radiation from moving target, therefore just have the title of passive type.Passive type infrared eye utilizes pyroelectric effect to survey, ordinary people knows from experience the specific wavelength infrared ray of transmitting 10 μ m left and right, just whether can detect targetedly this ultrared existence with custom-designed sensor, when human body infrared be irradiated on sensor after, because pyroelectric effect will outwards discharge electric charge, subsequent conditioning circuit just can produce control signal after processing after testing.This custom-designed probe is only the sensitive for infrared radiation of 10 μ m left and right to wavelength, so other objects except human body can not cause probe action.Once have in people's intrusion detection region, human infrared radiation focuses on by partial mirror, and received by pyroelectricity unit, but two heat differences that pyroelectricity unit receives, and pyroelectricity is also different, can not offset, so output detection signal.
In the present embodiment, the signal input part of the signal output part of microprocessor unit 1 and GSM modulator-demodular unit 3 is connected, and GSM modulator-demodular unit receives after coherent signal, send information to specific receiving equipment by the mode of wireless transmission.In the present embodiment, adopt TC35i Siemens industry gsm module, this module is a technical grade gsm module of supporting Chinese short message breath, be operated in EGSM900 and GSM1800 two-band, power range is direct current 3.3～4.8V, and current drain---dormant state is 3.5mA, and idle condition is 25mA, emission state is 300mA (on average), 2.5A peak value; Can transferring voice and data-signal.In native system, TC35i is connected by TTL serial ports with single-chip microcomputer.
