Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of ultrasound wave control module of the present utility model, comprise ultrasonic transmit circuit 1, ultrasound wave receiving circuit 2 and single chip machine controlling circuit 3, the output terminal of described ultrasonic transmit circuit 1 is connected to the input end of single chip machine controlling circuit 3, the input/output terminal of described ultrasound wave receiving circuit 2 is connected with the input/output terminal of single chip machine controlling circuit 3, and the output terminal of described single chip machine controlling circuit 3 is connected to the input end of RS485 communication interface circuit 31.
Described ultrasonic transmit circuit 1 by ultrasound wave emission sensor UM1 connect 6 groups of inverter ics 2 and resistance R 1, R2 constitutes, described ultrasound wave receiving circuit 2 connects CX20106A demoder IC3 by ultrasound wave receiving sensor UM2 and constitutes, when object when the ultrasound wave emission sensor UM1,6 groups of inverter ics 2 are formed the Transistor-Transistor Logic level circuit with resistance R 1, R2.After ultrasound wave emission sensor UM1 and ultrasound wave receiving sensor UM2 formation correlation, after 6 groups of inverter ic 2 carrier modulation are amplified, form with current field sends carrier signal, this signal is after ultrasound wave receiving sensor UM2 receiving circuit amplifies, after demodulation also goes out original numerical coding pulse signal, deliver to the 32nd end of 89S52 single-chip microcomputer IC1, decode through internal processor, the digital signal that ultrasound wave receiving sensor UM2 receives, be 0dB through CX20106A demoder IC3 gain amplifier, the 7th pin output pulse signal of CX20106A demoder I C3, the full gain size is by the external resistance R 1 of its 2nd pin, capacitor C 1 determines, resistance R 1 is more little or capacitor C 1 is more big, it is more high to gain, adopt the peak detection mode, detection capacitor C 2, resistance R 2 is bandpass filter, integrating capacitor C3, handle through CX20106A demoder IC3 pulse signal, the 7th pin output signal by CX20106A demoder IC3, reach the 32nd end of 89S52 single-chip microcomputer IC1 again, after 89S52 single-chip microcomputer IC1 inter-process is judged, connect to form RS485 communication interface circuit 31 by 89S52 single-chip microcomputer IC1 and SN75176 communication interface chip IC5, send the driving command signal by 89S52 single-chip microcomputer IC11 to SN75176 communication interface chip IC5, after SN75176 communication interface chip IC5 decoding, by the standard interface outputting data signals, can connect various instrument or industrial control equipment, have very high compatibility, be widely used in reversing radar of vehicle, level gauging, fields such as range finding.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
