Fig. 2 has schematically shown battery powered wireless motion detectors or has had detecting device 1.Detecting device 1 comprises proving installation 100,101,102 and the control module 103 that is used to produce with evaluate test signals 100b, utilizes described test signal 100b can detect the motion of target or has 100a.To moving or existing the detection of signal 100b to realize by sampling equally.It is power autonomous 105 that detecting device 1 comprises, it is used for the intermittent at least power supply of at least one power consumption components 100,101,102,103,104 of detecting device 1.Power consumption components is specifically related to: motion sensor 100, Data Detection parts or signal processing unit 101,102, be used to discern people's electronics assessment unit 103 and communication component 104.Target to be detected can relate to people, animal, bicycle, automobile etc.Motion detector 1 comprises for example heat-ray sensor 1 (PIR), but also can comprise: based on the active IR detecting device of infrared external reflection, based on the active ultrasonic detector of ultrasonic reflections or Doppler effect, noise detector, active microwave detector etc.With the widely used heat-ray sensor of Reference numeral 100 expressions, described detecting device comprises two pyroelectric crystal A, A ', and these two pyroelectric crystals link together according to opposite polarity.Heat radiation 100a based on the thermal target that is moving, crystal A, A ' sends characteristic Electronic Testing signal 100b, it is amplified in advance by comprising the field effect transistor that drain D, the collection utmost point and capacitive character are connected to the source S of ground connection GND, in signal amplifier 101, further amplify, in A/D converter 102, convert digital signal to, and finally evaluated in microcontroller 103.Especially, under the situation that modified is used, when the installation site of storage does not have direct electric power master network inlet or when system comprises a plurality of sensors and actuator 2, need allow detecting device 1 be independent of actuator 2 installations.Like this, should be able to utilize battery 105 sensor element 1 that turns round, and, 2 switch command preferably transmitted from sensor 1 to actuator by wireless connections 3.For this reason, detecting device 1 has transmitter 104, and actuator 2 has receiver 204, and they can play a role based on radiowave, microwave, sound wave etc.In addition, in order to control light source, veil, fan, air-conditioning unit, heating system or other electrical equipment, actuator 2 comprises independent microcontroller 203 and switch 200, particularly postpones or semiconductor switch 200.If there is the additional control that depends on light, then photosensitive part 5 can be photoelectric cell, light resistance (LDR=photoresistance), phototransistor etc.In addition, between detecting device 1 and actuator 2, be under the situation of radio communication, give the outline 3 of actuator 2 except being used to transmit order, can also have towards returning of detecting device 1 and communicate by letter 4.Return communication 4 and be used for transmitting how connect role to detecting device 1 notice, if necessary, be adjusted to optimizing level, particularly make its reduction so that will transmit output level from actuator 2.
Fig. 3 shows the traditional method of sampling 12 and the method for sampling of the present invention 13, in traditional method of sampling 12, implement test signal 100b continuously in uninterrupted mode, the sampling 12 of 101b, in contrast, in the method for sampling 13 of the present invention, in order to reduce power autonomous 105 power consumption I, implement the sampling 13 of test signal 101b quasi-continuously, promptly, the sampling time section 14 that qualification is implemented to sample in uninterrupted mode ', and allow sampling time section 14 ' between do not implement the sampling gap 14 of sampling.In other words, replaced equidistant or continuous at least sampling 12, implemented sampling with the pulse mode 13 that wherein allows detector gap or sampling gap 14.Therefore, it is constant substantially or constant to keep sample rate f, but intermittently suspends or interruption.Like this, just can be independent of the remaining life of battery 105 basically and carry out pulse mode 13.The following describes several embodiment.
Should be according to required test signal 101b, the availability of 100b, particularly be the availability of required gas consumption signal 101b or motor message 100b, select dead time during the sampling gap 14 and sampling time section 14 ' during the ratio of wakeup time.Can realize power saving like this: during sampling gap 14, disconnect power device 1,1 ' a plurality of preferred all power consumption components 100,101,102,103,104, perhaps, if desired sampling time section 14 ' automatically exciting, then above-mentioned a plurality of preferred all power consumption components are switched to stand-by state.For this reason, for example microcontroller 103 is waken in for example running in microcontroller 103 of clock the every 0.1s of described clock or 1s or 10s, and generation sample window 14 '.

1The traditional sampling rate of=75Hz has realized the prediction battery T in serviceable life in 5 years
EIf after 4 years, f
1The sampling rate of=75Hz is decreased to f
2=60Hz, then extending to serviceable life just is 6 years, and, utilize to be decreased to f once more
3=45Hz then extends to above 6 years serviceable life.Therefore, with the detecting reliability that relatively reduces a little, system 1 can turn round considerable time, all exhausts until the electric capacity of battery 105.Above-mentioned sample rate f

1, f
2, f
3Also must be with the behavior that allows sampling gap 14 as the function of wanting monitored area of space, as the function of visual field, and determine as the function of a plurality of motion detectors 1.In any situation, wish to guarantee minimum sample rate in the cycle at minimum time so that guarantee at least off and on device 1,1 ' function electric capacity.
