Description
Technical field
The utility model belongs to Range Measurement System technical field, especially relates to a kind of ultrasonic distance and surveys
Amount system.
Background technology
The most common distance-finding method has laser ranging, radar range finding and ultrasonic ranging etc..Wherein laser
Range finding is to utilize laser to be measured the distance of target.Laser ranging operationally goes out one to objective emission
Restrainting thin laser, then photoelectric cell receives the laser beam of target reflection, and the counter in control circuit measures
From being transmitted into time of reception, thus calculating observation person's range-to-go.Radar range finding and laser ranging
Close, its advantage is that range finding range is big, but power consumption is big, price is high, and use occasion is limited to.
In above-mentioned several distance-finding method, the speed of ultrasonic wave is little relative to the light velocity many, it is easy to analogue simulation.
Ultrasonic wave is the frequency mechanical wave more than 20KHZ, and it has the Basic Physical Properties of sonic transmissions equally
Reflect, reflect, interference etc., ultrasonic wave can reflect at most of energy of different medium faces ultrasonic wave.Super
Sound ranging is that one utilizes Ultrasonic characteristics, electronic technology, optoelectronic switch to combine to realize noncontact
The method of formula range measurement.
Existing ultrasonic range finder comprises single-chip microcomputer, separate display screens, button, battery and ultrasonic wave biography
Sensor, and use single-chip microcomputer and the ultrasonic range finder shortcoming of display screen the most gradually to manifest, bring Gao Gong
Consumption, the defect of high cost, certainty of measurement is not high enough simultaneously.
Summary of the invention
The utility model provides a kind of certainty of measurement high and lower-cost ultrasonic distance measures system.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of ultrasonic distance is measured
System, the signal processor being connected with described ultrasonic sensor including ultrasonic sensor and with institute
Stating the data display equipment that signal processor connects, described ultrasonic sensor includes for tested barrier

Acoustical range estimates the distance calculation module that module connects, and described data display equipment includes distance display module,
Described distance display module is connected with described distance calculation module.
Further, described ultrasonic distance measure system also include respectively with described ultrasonic wave transmitter module,
The ultrasonic control module that described ultrasonic wave receiver module connects, described ultrasonic control module connects useful
In the analog signal sending module that the analog signal of return is transmitted to described signal processor.
Further, described signal processor also includes that analog signal receiver module, described analog signal are sent out
Module is sent to be connected with described analog signal receiver module, described analog signal receiver module and described ultrasonic wave
Scope is estimated module and is connected.
The utility model ultrasonic distance measures system, by described ultrasonic wave transmitter module to tested obstacle
Thing launches ultrasonic signal, the analog signal returned by tested barrier by described ultrasonic wave receiver module
Being received, analog signal after reception sends to be estimated module to ultrasonic wave range to carry out ultrasonic wave range pre-
Estimate, carry out the data after ultrasonic wave range is estimated and send to described distance calculation module, calculate final
Measure distance, finally measurement distance is sent extremely described data display equipment and show.The utility model surpasses
Sound wave Range Measurement System, uses ultrasonic wave range predictor method to carry out distance and calculates, have range measurement
The advantage that precision is high, system cost is low.
Accompanying drawing explanation
Fig. 1 is the structured flowchart that the utility model ultrasonic distance measures system.
Detailed description of the invention
Below in conjunction with the accompanying drawings specific embodiment of the utility model is elaborated.

From computing module, described data display equipment includes distance display module, and described distance display module is with described
Distance calculation module is connected.
Described ultrasonic distance measure system also include respectively with described ultrasonic wave transmitter module, described super
The ultrasonic control module that acoustic receiver module connects, controls institute respectively by described ultrasonic control module
State ultrasonic wave transmitter module, the transmitting of described ultrasonic wave receiver module, receive work.
Described ultrasonic control module connects to be had for the analog signal that will return to described signal processor
The analog signal sending module being transmitted.Described signal processor includes analog signal receiver module, institute
State analog signal sending module to be connected with described analog signal receiver module, described analog signal receiver module
Estimate module with described ultrasonic wave range to be connected.
The utility model ultrasonic distance measures the course of work of system: described ultrasonic control module is first
Controlling described ultrasonic wave transmitter module and launch ultrasonic signal to tested barrier, described ultrasonic wave controls mould
Block controls described ultrasonic wave receiver module again and the analog signal that tested barrier returns is received, and receives
After analog signal sent to described analog signal receiver module by described analog signal sending module, institute
State analog signal receiver module to retell analog signal and send to described ultrasonic wave range and estimate module and surpass
Acoustical range is estimated, and carries out the data after ultrasonic wave range is estimated and sends to described distance calculation module, surveys
Calculate final measurement distance, finally measurement distance transmission is carried out data to the most described distance display module and show
Show.
Above preferred embodiment of the present utility model is described in detail, but described content has been only this reality
With novel preferred embodiment, it is impossible to be considered for limiting practical range of the present utility model.Fan Yiben
