Description
Technical field
This utility model relates to a kind of supersonic range finder, is specially a kind of ultrasonic distance-measuring sensor Teaching Module.
Background technology
In the last few years, along with the raising of people's living standard, more and more there has been the private car of oneself in China, and traffic is more and more crowded, drives a vehicle or often can use ultrasonic measurement in reversing process；Additionally construction building site and the monitoring position of some industry spot, liquid level, the degree of depth of well, duct length etc. measure occasion, it is necessary to are accurately positioned and measure, also can use ultrasonic measurement.Visible ultrasonic measurement range of application is widely.But the ultrasonic measurement instrument on market is on the high side, and the research funding of general school is all fewer, the particularly school of remote districts, the instruments used for education of high cost of at all cannot afford.Therefore, it is not appropriate for carrying out popularization and application as the instruments used for education of school.
Summary of the invention
In order to reduce instruction cost, sensor teaching devises ultrasonic sensor Teaching Module, allow student fully understand operation principle and the application of ultrasonic distance-measuring sensor, be better Teaching Service, closer to the demand of actual application environment.
Design of the present utility model is as follows: a kind of ultrasonic ranging Teaching Module, including housing and the pcb board being encapsulated in housing, pcb board is provided with controller and the ultrasound wave receiver module being connected with controller, ultrasonic emitting module, described ultrasound wave receiver module is made up of the ultrasonic receiver being sequentially connected with, signal amplification circuit and phaselocked loop detecting circuit, received ultrasonic signal also converts a signal into voltage signal, and sends a signal to the A/D passage that controller is logical；Described ultrasonic emitting module is connected ultrasonic transmitter by amplifying circuit and constitutes, and receives the control signal of controller and launches ultrasonic signal；Described case panel is provided with display, button keyboard and alarm module, is connected with controller respectively through circuit.Described alarm module includes LED light and the sound and light alarm of buzzer composition.Described display is 4 LED nixie displaies.Described button keyboard includes on and off switch, arrange key and distance arranges key.This Teaching Module realizes hyperacoustic transmitting and reception, utilizes ultrasound probe detection to return the time of sound source after arriving object from sound source, calculates from sound source range-to-go, complete range operation.Utilize hyperacoustic high reliability and contactless property, and detectable signal is converted to voltage signal, convert to through A/D converter and after digital signal, give Single Chip Microcomputer (SCM) system, single-chip microcomputer and respective peripheral circuit thereof carry out the process of signal, it is shown that sound source is to the distance between object.
This Teaching Module utilizes ultrasonic emitting and reception, the distance of object position in detection environment, and has sound and light of alarm.Modular structure is succinctly light, and parts all select common device, and production cost is low, is suitable for using with education experiment.

Detailed description of the invention
Below in conjunction with specific embodiment and Figure of description, the utility model is described in further detail.Specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Embodiment: as shown in Fig. 1～Fig. 2, a kind of ultrasonic ranging Teaching Module, including housing and the PCB being encapsulated in housing.PCB is provided with controller and the ultrasound wave receiver module being connected with controller, ultrasonic emitting module.Described ultrasound wave receiver module is made up of the ultrasonic receiver being sequentially connected with, signal amplification circuit and phaselocked loop detecting circuit, and received ultrasonic signal also converts a signal into voltage signal, and sends a signal to the A/D passage that controller is logical；Described ultrasonic emitting module is connected ultrasonic transmitter by amplifying circuit and constitutes, and receives the control signal of controller and launches ultrasonic signal.Controller adopts CMOS8 8-digit microcontroller chip STC89C52, adopts 74HC04 phase inverter and CX20106 to beat connection circuit and realize hyperacoustic transmitting and reception.Detectable signal is converted to voltage signal by ultrasonic receiver, and peripheral circuit carries out the process of signal, is calculated measuring sound source to the distance between object after the A/D converter of single-chip microcomputer converts digital signal to.
The panel of housing is additionally provided with 4 LED nixie displaies 6, button keyboard and alarm module, is connected with controller respectively through circuit, and is controlled by controller.Described display is 4 LED nixie displaies 6, is used for showing measurement distance.Described alarm module includes LED light and buzzer, and sound, light are reported to the police and combined.Described button keyboard includes on and off switch 1, arrange key 2 and distance arranges key 3, and on and off switch is used for power-on, arranges key and distance arranges bond and closes the upper distance limit used for arranging warning.When object distance exceedes the upper limit of setting LED light 4 glimmer, buzzer 5 sounding alarm；When object distance is lower than when arranging the upper limit, LED light 4 is extinguished, buzzer 5 stop alarm.
It is this utility model preferred embodiment in sum, all changes made according to technical solutions of the utility model, belong to protection domain of the present utility model when the function produced is without departing from the scope of technical solutions of the utility model.
