Abstract :
A kind of rock bolts length measuring system using techniques of embedded system and ultrasonic waves is proposed. It can realize controlling for circuit of ultrasonic transmitting, circuit of ultrasonic wave receiving, electrical source, circuit of A/D transforming, keyboard, LCD, loudhailer etc by program, and analyzing signal of reflecting ultrasonic waves. The system´s MCU is LPC2210 in the series of ARM7 and make uC/OS-II as operating system. The paper pays more attention to the theory of ultrasonic measuring and scheme of system for realizing.
