Embodiment
The invention will be further described for composition graphs 1 to Fig. 3, a kind of going out prompting device, the first body induction circuit, the confirmation circuit of going out that arrange before and after comprising, and prompting control circuit; Described first body induction circuit induction human body radiation signal, exports the first electric signal to described prompting control circuit; Described going out confirms circuit inductance human body radiation signal, exports the second electric signal to described prompting control circuit; Described prompting control circuit receives the first signal that described first body induction circuit exports simultaneously and describedly gos out when confirming secondary signal that circuit exports, exports electric signal driving circuit and sends cue.
As shown in Figure 1, described first body induction circuit comprises the first human body pyroelectricity infrared sensor U2, the the first rpyroelectric infrared control integration circuit U 1 be connected with described first human body pyroelectricity infrared sensor, described first human body pyroelectricity infrared sensor U2 receives the infrared signal of human body radiation, export electric signal, after the low-pass filter filtering interference signals that electric capacity C5 and resistance R4 forms, input pin 2 pin through described first rpyroelectric infrared control integration circuit U 1 inputs, as input signal, sensing signal amplifies through secondary, whether triggering is had again through window voltage multilevel iudge, have, export control level.The now controlled beginning timing of timer, enters delay state, is greater than the 768T(clock period when the U2 detection signal time) time, just export high level, to prevent false triggering.When timing output and zero passage detection go out simultaneously for high level, just can export positive pulse, export high level signal by output pin 11 pin, described high level signal inputs through described prompting control circuit input pin; Export the TCI clock control of time by 8 pin of high level, the length of high level time is changed by the resistance changing RP1, the time that this circuit is arranged is 9 seconds, namely when people will go out or through induction region, the first body heat pyroelectric sensor U2 induces the infrared signal of human body radiation, exports the high level of about 9 seconds at 11 pin of U1.
As shown in Figure 2, described going out confirms that circuit comprises the second body induction circuit, and be connected to the reverser of described second body induction circuit output terminal, described reverser is made up of triode VT1 and peripheral circuit, the principle of work of described second body induction circuit is identical with the principle of described first body induction circuit, described second body induction circuit comprises described second human body pyroelectricity infrared sensor, the the second rpyroelectric infrared control integration circuit be connected with described second human body pyroelectricity infrared sensor, described second human body pyroelectricity infrared sensor receives the infrared signal of human body radiation, export electric signal, input pin through described second rpyroelectric infrared control integration circuit inputs, high level signal is exported by output pin, through described reverser output low level signal, described prompting control circuit receives the first signal of described first body induction circuit output and the described secondary signal confirming that circuit exports of going out, and exports electric signal driving circuit and sends cue.Although the described principle of work of the second body induction circuit is identical with the principle of the body induction circuit of body induction circuit, but now the detection signal time can shorten, no longer carry out time controling, signal detected at short notice, just an of short duration low level is exported at the collector of triode VT1, the time of output low level signal, by resistance adjustment, is adjusted to 3 seconds here; The time of detection signal, the time of output high level and the time of detection signal, the time of output low level in the second body induction circuit in the first body induction circuit, with the installation site of the second human body pyroelectricity infrared sensor in the first human body pyroelectricity infrared sensor U2 in described first body induction circuit and described second body induction circuit and distance dependent between the two, can regulate according to both installation sites and distance between the two.
As shown in Figure 3, described prompting control circuit comprises NE555 integrated circuit and hummer, and the output pin of described NE555 integrated circuit is connected with described hummer with switching tube VT2 by resistance, when described first body induction circuit
end exports high level, confirmation circuit of going out simultaneously
during end output low level, respectively through the 4 pin input high levels of NE555, through the 2 pin input low levels of NE555, meet trigger condition, enter temporary stable state, 3 pin of NE555 export high level, described switching tube VT2 saturation conduction, hummer is sounded, and to going out, people reminds, and whether forgets band thing.But when people enters, 2 pin of NE555 have triggering level, but because U2 detection signal time controling is longer in described first body induction circuit, described first body induction circuit does not trigger, now 4 pin are still low level, NE555 does not work, when people arrives the first pyroelectric infrared sensor U2 of described first body induction circuit, although 4 pin are high level, but go out described in should be and confirm that the time of circuit output low level is shorter, 2 pin are transformed to high level by low level, and prompting device can not be sounded, false alert when effectively preventing people from entering.
