Background technology
Traditional ultrasound measurement module is in order to ensure measuring distance, and commonly used 16mm*12mm sonac, employing I O trigger range finding, host computer automatically sends the square wave of 40KHZ to the high level signal range finder module of, automatically detected whether that signal returns；Having signal to return, export a high level by IO, high level duration is exactly that ultrasound wave is from the time being transmitted into return. and host computer goes out distance by Time Calculation.Although but this kind of relatively low performance of scheme cost is the most unstable, and a low and high level signal can only be given, the distance of actual test cannot be calculated, host computer is needed to be calculated by algorithm, take host computer resource, and the compatibility of product is not strong, needs host computer again to develop, additionally overall volume and weight are relatively big, cause the weight of range finder module and area bigger.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, it is provided that a kind of smart structural design, rationally, finds range effective, and volume is little, the ultrasound measurement module of the low blind area of lightweight high accuracy.
The technical scheme that this utility model is used for achieving the above object is: the ultrasound measurement module of the low blind area of a kind of high accuracy, it includes ultrasound emission sensor, ultrasonic reception sensor, signal processing chip, boost chip and single-chip microcomputer, described ultrasound emission sensor is connected with single-chip microcomputer by boost chip, and described ultrasonic reception sensor is connected with single-chip microcomputer by signal processing chip.
As further improvement of the utility model, described signal processing chip includes one stage signal amplification treatment circuit and second signal amplification treatment circuit.
As further improvement of the utility model, described ultrasound emission sensor and ultrasonic reception sensor are disposed side by side on upper surface two side position of wiring board.
As further improvement of the utility model, described signal processing chip and boost chip are arranged on the upper surface centre position of wiring board.
As further improvement of the utility model, described single-chip microcomputer is arranged on the lower surface of wiring board.
The beneficial effects of the utility model are: this utility model smart structural design, rationally, single-chip microcomputer drives ultrasound emission sensor by boost chip, emission sensor sends the square wave of certain frequency, pass back through ultrasonic reception sensor after running into object and receive signal, signal enters single-chip microcomputer with amplifying after filtering by signal processing chip, and single-chip microcomputer calculates distance, carries out data transmission to host computer by IIC communication, reduce and take host computer resource, find range effective；And signal processing chip is for closely different with the intensity of remote echo-signal, employing two-stage is amplified, one-level is closely used to amplify, solve that blind area is big and the problem of measurement of near distance precision, two grades of amplifications of remote employing, solve distance precision and the problem of stability, realize closely separately processing with distant signal, detection accuracy, blind area and distance excellent performance, additionally compact overall structure, volume is little, lightweight, the avoidance of current all kinds of robot can be met completely, fixed height, the requirements such as buffering, it is particularly well-suited to the technical fields such as the most growing legerity type robot or unmanned plane.
Below in conjunction with the accompanying drawings with embodiment, this utility model is further illustrated.
