The principle of work of present embodiment.Each ingredient of the warning device of present embodiment is worked under the power supply of power module 3.
1. the work of infrared module 4: the power input VCC of infrared module 4 is connected with the power output end of power module 3, and infrared module 4 is worked because of the power supply that obtains power module 3.Wait for half a minute adaptation time, at this moment the output terminal IR output low level of infrared module 4.Before passive type human body pyroelectricity sensor, rock the output level saltus step of the output terminal IR of infrared module 4, output high level with hand.Start timing circuit, the extended period T=20 second of timing circuit.
2. the work of key press module 5: the power input VCC of key press module 5 is connected with the power output end of power module 3, and key press module 5 is worked because of the power supply that obtains power module 3.When any one button in the key press module 5 was not pressed, the output terminal OUT of key press module 5 exported high level.Push button first of modular pressure 5～the 5th button (during any one button among the K1～K5), the output terminal OUT output low level of key press module 5.
3. operation below carrying out under the control of the program among the ROM of the CPU of single-chip microcomputer 1 in single-chip microcomputer 1 and the commander:
The first step continues to detect the output level of first mouthful of line P0.0, promptly detect the output signal of the output terminal IR of infrared module 4, when the output level of first mouthful of line P0.0 is high level, the infrared zone bit set of infrared module 4, start timing circuit, the extended period T=20 second of timing circuit;
Second step was detected the output level of the 3rd mouthful of line P0.2, it is the output signal of the output terminal OUT of key press module 5, when the output level of the 3rd mouthful of line P0.2 is a high level, then continue to detect a period of time again, (as 20 seconds) are high level as the output level that still detects the 3rd mouthful of line P0.2, then the infrared zone bit of infrared module 4 are resetted, as the output level that detects the 3rd mouthful of line P0.2 is low level, then the key press zone bit set of key press module 5;
When the infrared zone bit of hot outer module 4 of the 3rd step and the key press zone bit of key press module 5 all are in set, trigger end IN to buzzer warning module 6 sends high trigger signal, make buzzer warning module 6 send chimes of doom, simultaneously the key press zone bit of the infrared zone bit of infrared module 4 and key press module 5 is resetted.
Embodiment 4 car alarms
Except for the following differences, present embodiment has 3 identical structure and the circuit with embodiment.The device of present embodiment can with the automobile coupling, passive type human body pyroelectricity sensor is contained in the door handle position of the door of outer driving of automobile and front passenger's seat, being used for to stranger's body activity monitors, whether key press module 5 places under the seat cushion at each seat, be used for monitoring taking on the seat.In case the burglar is arranged from invading outdoors, passive type human body pyroelectricity sensor has induction, be sitting on the seat when preparing to start up the car as the burglar simultaneously, button in the modular pressure 5 is equivalent to push button, key press module 5 triggers, because the set simultaneously of infrared zone bit and key press zone bit, single-chip microcomputer 1 sends trigger pip to buzzer warning module 6, and buzzer warning module 6 is reported to the police.If general pedestrian is other through out-of-date from car, because key press module 5 does not trigger, the hummer of buzzer warning module 6 can not reported to the police, but single-chip microcomputer 1 can keep passive type human body pyroelectricity sensor signal a period of time, measures in advance as the time of burglar's phagocytic process.Otherwise, if the car owner places weights such as luggage on back row seats, though 5 triggerings of key press module, owing to passive type human body pyroelectricity sensor does not trigger, so the hummer of buzzer warning module 6 can not reported to the police yet.
Embodiment 5 anti-intrusion alarm devices
Except for the following differences, present embodiment has 3 identical structure and the circuit with embodiment.Apparatus of the present invention and above-mentioned auto alarm device are identical, passive type human body pyroelectricity sensor places on the doorframe place, angle or place, angle on window frame, direction outwardly, being used for to stranger's body activity monitors, key press module 5 places below the carpet of doorway or on the windowsill, is used for monitoring the someone invades.In case there is the invador to enter, at first infrared module 4 is triggered, when in invador's inlet chamber, step on a button in five buttons of key press module 5, because infrared zone bit and key press zone bit set simultaneously, single-chip microcomputer 1 sends trigger pip to the trigger end IN of buzzer warning module 6, the buzzer warning of buzzer warning module 6.As the people is arranged outdoors, as the salesperson, though infrared module 4 is triggered, because the people does not enter, key press module 5 does not trigger, the hummer of buzzer warning module 6 can not reported to the police, otherwise, as indoor no one, because pet steps on a button in five buttons that suffered key press module 5, because infrared module 4 is not triggered, so the hummer of buzzer warning module 6 can not reported to the police yet.
