基于PSoC的超声波测距及其语音播报系统设计与实现
作者__ 张昊天
指导 马学文副often rapid, convenient, simple calculation and easy to do real-time control, And the measurement accuracy to achieve industrial and practical requirements. The ultrasonic distance measurement principle is the use of ultrasonic propagation velocity in the air is known, measuring the sound waves encounter obstacles reflected back after launch, according to the transmitting and receiving time difference to calculate the actual distance to the launch point to the obstacles. Thus, the principle of ultrasonic ranging and radar principle is the same. Based on the above reasons ultrasonic distance measurement used in reversing reminder, construction sites, industrial sites, such as distance measurement.
This article describes a design based on SrF06 ultrasound module. Accurate measurement of distance, and the number of voice reporting on the basis of analysis of the development status and work characteristics of ultrasonic distance measurement at home and abroad, combined with the characteristics of PSOC to makes project of more humane.
The system uses the the CYPRESS company PSOC3 as the main development platform, its most important feature is integrated in its core surrounded by a large number of devices, and almost no need other external devices. .The design by its own integrated counter to count the length of echo signal and then by the algorithm to determine the distance.

Own integration of DA on the digital signal processing which can then be amplified by its own OPMAP zoom and real-time voice signal by io port output. The system uses the PSOC CRETER software to compile the program. Which includes not only the compilation of the code also includes the compilation of is also a feature of psoc. By MiniProg3,the program downloaded to the chip, and then tes
