Forming a working frequency by loop aerial and microwave triode inside highly reliable microwave induction controller is
The microwave oscillator of 2.4GHz, loop aerial had both done transmitting antenna or can receive the echo reflected by human motion.It is internal micro-
Beat detects faint frequency shift signal (detecting the movable signal of human body), microwave after the semiconductor PN mixing of wave triode
Special microprocessor HT7610A removes the too small interference signal of amplitude first and is only converted to the detection frequency shift signal of some strength
Constant amplitude pulse of different size, circuit only identify the sufficiently wide monomer signal of pulse, as human body, vehicle its discriminator circuit ability are touched
Hair had 2~3 burst pulses in two seconds, such as takes precautions against edge people from area and walks about 2~3 steps, width discriminating circuit is also triggered, and starting is prolonged
When, control circuit work.If it is weaker interference signal, such as the animal of small size, remote trees shaking, high frequency communications
The interference generated when signal, remote lightning and Household appliance switch is excluded.Last HT7610A identifies real big object
When body movable signal, control circuit is triggered, the high level of output 2 seconds or so, and has LED2 simultaneous display, and the way of output is electricity
Pressure mode is high level (8 volts or more) when having output, is low level when not exporting.
The clock frequency of the dedicated microprocessor HT7610A of microwave is 16KH, and when first power-up, system will be latched 60
Second, it during which completes the initialization of microprocessor and establishes electric field, at this moment LED extinguishes after glittering 60 seconds, and system is automatically into detection
State will have signal output in 2 seconds, and synchronized and lighted by indicator light LED when detecting useful signal.
Very reliable, the typically no wrong report of highly reliable microwave induction controller work, is previous infrared ray, ultrasonic wave, heat
Warning circuit and the conventional microwave circuit for releasing electric device composition are incomparable, are currently used for safety precaution and automatic prison
The best product of control.
Power unit forms constant pressure, current limliting floating charging uninterruptible power supply by the lead-acid accumulator and LM317 of 12V/1.2Ah,
It may insure that battery is in sufficient electricity condition at any time, alarm can be made to work normally in the case where mains failure, plumbic acid
The float charge voltage of battery is 14.2V, and LM317 is connected into constant pressure source, output terminals A point can be made to export by adjusting W stable
14.9V DC voltage, resistance R4 can limit that charging current is excessive, and D2 can prevent battery back discharge after mains failure.
TWH9236/9238 is remote-transmitter, receiving unit, when any in A, B, C, the D for pressing transmitter TWH9236
When one key, A, B, C, D output end of receiver TWH9238 can also correspond to output high level, and lock when saving output
State.It here is alarm work button by A key assignments, other three key assignments are alarm releasing button.As long as so
Transmitter A key is pressed, the A output end of receiver will export 4 volts or so of high level and holding, then press by transmitter B, C, D
Key any one when receiver A output end will become low level again and keep.
When A output end exports high level, triode T1 is connected by resistance R1, relay J is attracted, 12V positive supply
The power end of highly reliable microwave induction controller is added to by relay contact, Light-emitting diode LED is lighted at this time, instruction alarm
Device has worked, after highly reliable microwave induction controller initialization in 60 seconds, alarm life's work, as long as at this moment existing
Monitoring area has human action, and the white line output end of highly reliable microwave induction controller will export drop-down in 10 seconds or so
T2 is connected in signal, and high loudness alarm TWH-11 will issue police's alarm of 120dB.When A output end exports low level
When, relay J is disconnected, and highly reliable microwave induction controller cannot get operating voltage so not working.
As shown in figure 4, processing flow schematic diagram of the invention:
1, action message is obtained to be completed by microwave induction controller；
2, action message output voltage control signal after microwave induction controller is handled,
3, thus diode is lit, and makes a sound alarm speaker.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Within protection scope of the present invention, therefore, protection scope of the present invention should be based on the protection scope of the described claims lid.
