The present invention is made up of ballistic device (8) and (9) two parts of receiving device, and wherein ballistic device comprises stainless steel casing (6), the ultrasound emission transducer, and circuit board (3), two external power supply lead-in wires (1,2), epoxy resin is filled out envelope (4); Receiving device comprises stainless steel casing (6), ultrasonic receiving sensor, and (3) two external power supply lead-in wires of circuit board (1,2), an output line (7) and epoxy resin are filled out envelope (4).Its ballistic device separates with receiving unit, can constitute easily as shown in Figure 2 the transmission-type assembly or reflective assembly as shown in Figure 3, ballistic device has two outer leads, receiving device has three outer leads.
The circuit configurations of ballistic device of the present invention is:
With IC555 is core, connect into typical astable multivibrator, it is 4., 8. pin is just connecing power supply, 1. pin ground connection, and 5. pin is by C2 ground connection, 7. pin is just connecing power supply by R1,2., 6. pin links, R2, the R3 series connection connects 7. pin and 6. pin respectively, 2. pin is through C1 ground connection simultaneously, and ultrasound emission transducer HN1 meets IC555 respectively and exports 3 pin and ground connection.
The circuit configurations of receiving device of the present invention is:
Ultrasonic receiving transducer HN2 connects V1 base stage and ground connection respectively, and collector electrode is just connecing power supply by R1, and R2 connects the collector electrode base stage respectively, the V1 collector electrode connects the V2 base stage, and the V2 collector electrode connects the V2 base stage, and the V2 collector electrode is just connecing power supply by R3, R2 is in parallel with C2, respectively sending and receiving emitter-base bandgap grading and ground connection.C1 one termination current collection collection also connects output by D1, D2 plus earth, and negative pole connects the D1 positive pole.
Working method of the present invention and principle are:
When the circuit of ballistic device powered up, C1 voltage was for triggering IC555 output high level, and the internal discharge triode ends.Power supply charges to C1 by R1, R2, when the voltage on the C1 surpass VCC 2/3 the time, trigger the IC555 output low level, the conducting of discharge triode, so C1 by the triode discharge of R2 and conducting, when the discharge of the voltage on the C1 is low to moderate 1/3Vcc, can triggers IC555 output and be uprised by low, the discharge triode ends, and power supply charges to C1 by R1, R2 again.Go round and begin again, form vibration f ≈ 1.443 (R1+2R2) C1.
When receiver HN2 receives the ultrasonic pulsative signal of the modulation that reflector sends here, just produce vibration, signal is after the direct coupled amplifier that V1, V2 form amplifies, and the detecting circuit of being made up of to D1, D2 capacitor C 1 coupling forms direct impulse and exports.This pulse can be directly used in the control miscellaneous equipment, or is connected with other various circuit and finishes multiple function.
In the present embodiment, radiating circuit is made up of 555 time-base circuits, and frequency of oscillation is 40Hz.Ultrasonic wave emission receiving sensor adopts VCM-40-12 (16) T/R.Receiving circuit is made up of simple discrete component, and V1, V2 are with low power tubes such as 9013, and all elements all adopt surface mount elements and little potted element.For easy to use and enhancing versatility, emitting module and receiving unit two parts have been formed respectively.According to the real work needs, size of components is divided into two kinds, and a kind of is miniature, ∮ 16 * 20mm, and another kind is a superminiature, ∮ 12 * 25mm uses MT-6/MR-16 respectively, and UMT-12/UMR-12 expression.M represents miniature, and UM represents superminiature.T represents emission, and R represents to receive.Circuit board ∮ 14 single sided boards in miniature, circuit board is 12 * 10mm single sided board in the superminiature.Emission, receiving unit can constitute the reflective and transmission-type structure of separation easily.
