Operation principle of the present utility model is:

(1), detects reflector: detect reflector+12V power supply and introduce circuit by D601; the D601 effect has two; the one, constitute blocking-up type and prevent that electric power polarity from connecing anti-protective circuit; the 2nd, can effectively reduce interference signal from power supply; C601 and C602, C603 are connected on the input and output side of voltage stabilizing circuit IC602 (78L06) respectively, play filtering and anti-interference effect.IC602 then provides a stable 6V operating voltage for this machine.

Supply power voltage monitoring/normal online signal generating circuit, after the energized, this circuit is at its output (OUT end, low level is effective) promptly produce cyclical intermission short pulse output, it is shorter that just often LED201 lights the time, and when sampled voltage is lower than the threshold value of IC2B setting, the 7 pin output low levels of IC2B, connecting the low level output duration that makes IC2A by resistance R 205 increases, LED201 lights time lengthening, and whether can observe out intuitively very much supply power voltage according to the length that LED201 lights the time thus normal.Resistance R 201, R202 connect positive and negative power end respectively, its contact is sampling output, when its current potential is higher than the voltage reference reference potential that resistance R 203, D201 determine, 7 pin of voltage comparator ic 2 are high-impedance state, otherwise, IC2B is low resistive state (7 pin over the ground), and resistance R 205 is connected to ground by 7 pin, thereby R204, R207 junctional potential are descended.

IC2A and R206, R208, R209, R210, D202, D203, C201 etc. form the EDM Generator of Adjustable Duty Ratio oscillating circuit, the duty time is determined by R209, R210, be subjected to simultaneously R204, the influence of R207 junctional potential again, R204, R207 junctional potential are low more, and it is long more that then LED201 lights the time.

Its coefficient result is, voltage is LED201 intermittently about 10 seconds just often, lights 0.5 second, and LED201 was intermittently about 10 seconds when voltage was lower than set point, lighted about 1.5 seconds.OUT output is lighted the time corresponding to LED201.

Piezoelectric ceramic piece, four-operational amplifier and peripheral cell constitute little signal that shakes and detect and treatment circuit, and the sense signal that shakes that piezoelectric ceramic piece is collected is sent into IC101, and IC101A, IC101D amplify and shaping pulse signal.R102 sets multiplication factor, and C102 sets the upper frequency limit (this circuit only amplifies negative-going pulse) of the reducible sense signal that shakes, and further amplifies shaping (IC101D) back and is exported by 14 pin.

R105, R106, IC101C and RT101 constitute the adjustable threshold voltage comparator, and RT101 adjusts comparator sensitivity, and comparator output is taken out through D101 and exported (OUT1, low level alert signal) after the forward signal is amplified by Q101.R107, C103 value are all less in this one-level circuit, and time constant is less, and be comparatively sensitive to the sense reaction of shaking.

Another road signal is taken out after send into IC101B by R110 by D102, but C104 value big (greater than 22UF) in this level, the threshold level that R111, R113 set is also than higher, so the signal of this grade output only just responds to the long-term vibrations signal of high amplitude.The signal that IC101B sends amplifies back output (OUT2 by Q102.High-level alert signal).

In the foregoing circuit, the supply power voltage OUT that monitoring/normal online signal generating circuit is sent, little signal that shakes detects and treatment circuit is sent OUT1, OUT2, deliver to 10,12,11 pin of coding circuit IC601 (PT2262) respectively via the electronic switch of Q601, Q602, Q603 and peripheral element composition, by adding to radiating circuit after the IC601 encoding process, be radiated surrounding space by transmitting antenna.

(2), monitoring receiver: the 315MHZ coding signal that is received by antenna is delivered to the ANT end of receiver module, after its inner amplification demodulation, send 14 pin of data signals to decoding circuit IC501, state signal corresponding to transmitting terminal is sent at 12,17 pin 11, in decoding back, drives sound light alarming circuit respectively again after signal processing circuit IC502 handles.

R501 is the oscillation resistance of decoding circuit IC501,17 pin output high level explanation IC501 has received the radio signals (coincidence detection output) of same-code, after expanding stream, Q501 can light LED501, LED501 intermittently lights under the normal condition of acceptance, Q501 by the D504 bleed off C508 through lotus that R509 charges, C508 can not set up high voltage (less than 1/2VCC), so the IC502D voltage ratio is output as low level.

No matter in case what reason to cause receiving, decoding failure by, 17 pin do not have high level coincidence detection signal, Q501 ends, C508 loses discharge loop, its both end voltage will raise gradually, surpassed the mid-point voltage that sets by R510, R512, IC502D exports high level at once, add to the IC502A in-phase end by D506, thereby make IC502A also export high level immediately, one the tunnel lights LED 502 after Q502 expands stream, the other end makes Q505, Q506 saturation conduction through D507, R519, and the news Chinese percussion instrument of sound light alarming circuit sends chimes of doom.

Even if the above-mentioned course of work has illustrated that reflector suffers thoroughly to destroy or other any reasons cause linking the working mechanism that failure also can correctly be reported to the police.This technology is the accurate seamless link technology of so-called wireless type.

The high level signal that 12 pin of IC501 demodulate is OUT1 (the low level alert signal corresponding to transmitting terminal, as more weak vibrations, duration of shaking is short etc.) by R503, R502, after C509 filtering, add to the IC502A in-phase end, IC502A can trigger aforementioned sound light alarming circuit equally; 12 pin go back to low level, and warning stops.

The high level signal correspondence that 11 pin of IC501 demodulate be that the OUT2 (high-level alert signal, as stronger or continuous vibrations etc.) of transmitting terminal adds to the IC502B in-phase end by D503, R504, C510, also will cause reporting to the police.Different is, because the access of D510, sound and light alarm is with self-locking, and warning also will continue even if 11 pin go back to low level, unless turn off receiver power supply, just circuit can reset.

IC502C and R506, R507, R508, D505, R511 constitute this machine and power that (this is particularly necessary when powered battery for under-voltage warning circuit! ), the sampled voltage that constitutes as R506, R507 is lower than R508, during reference potential that D505 sets, and the 14 pin output high level of IC502C, LED503 lights, and prompting should be changed battery.

In addition, the bright time correspondence of LED501 electricity be the OUT low level signal of transmitting terminal, under the normal condition should be intermittently light and the duration shorter, if the time of lighting obviously extends, the supply power voltage of then representing transmitting terminal should be checked supplying cell or boost charge (not carrying out audible alarm this moment) not in normal range (NR).

Among the figure, R521, R522, R523 are the current-limiting resistances of respective leds, and C511 is the shunt capacitance of U501 (news Chinese percussion instrument), and R506, R507 should look concrete condition and regulate definite.D501 is that the parallel connection type battery polar connects anti-protective circuit.Element was the electronic switch of U501 around Q505, Q506 reached, and was controlled by that D507, D508, D509 form or logical circuit.L501 and C504, C505, C506 are filter circuits, can be receiver module etc. higher power supply quality is provided.

Emission, receiver module used in the utility model all adopt commercially available finished product, so its circuit diagram no longer provides.

The wireless link monitor can adopt two kinds of coded systems in order to satisfy different requirements in the utility model, the one, common coding, the 2nd, rolling coding, operation principle that provides among the embodiment and schematic diagram all with common code-shaped be example, the rolling coding type is not being given unnecessary details.
