Abstract

The invention discloses an ultrasonic ranging device. A control processor and a temperature detection unit are connected for temperature detection, and then temperature compensation is conducted on measured ultrasonic data according to the environment temperature. The control processor and an ultrasonic emitting unit are connected for ultrasonic wave emission after signal amplification. The control processor and an ultrasonic receiving unit are connected to receive ultrasonic signals sent by the ultrasonic emitting unit. The control processor and an SCI communication unit are connected for serial communication, a power supply circuit supplies modular direct current working voltages and supplies power to the control processor, the temperature detection unit, the ultrasonic emitting unit, the ultrasonic receiving unit and the SCI communication unit. Ranging with the temperature compensation function can be achieved, and the ultrasonic ranging device is high in ranging accuracy, low in power consumption, convenient to use, easy to implement, and suitable for ranging of an education robot and other system applications.

Description

technical field [0001] The invention relates to a distance measuring device, in particular to a low power consumption, easy maintenance, high precision and low cost ultrasonic distance measuring device with temperature compensation function. Background technique [0002] In recent years, ultrasonic ranging technology has been more and more widely used. However, the current ultrasonic ranging system has high cost, complex implementation, high power consumption, and the measurement accuracy is affected by the ambient temperature, so the accuracy is low in practical applications. To this end, we have developed a low-power, easy-to-maintain, high-precision, low-cost ultrasonic distance measuring device with temperature compensation function. Contents of the invention [0003] The object of the present invention is to provide a low power consumption, easy maintenance, high precision and low cost ultrasonic distance measuring device with temperature compensation function in ord...
