ABSTRACT:
Ultrasonic ranging technology has wide using worth in many fields,such as the industrial locale,vehicle navigation and sonar it has been used in level measurement,self-guided autonomous vehicles, fieldwork robots automotive navigation,air and underwater target detection,identification,location and so there is an important practicing meaning to learn the ranging theory and ways deeply. To improve the precision of the ultrasonic ranging system in hand,satisfy the request of the engineering personnel for the ranging precision,the bound and the usage,a portable ultrasonic ranging system based on the single chip processor was developed.

1、Introductive
With the development of science and technology, the improvement of people's standard of living, speeding up the development and construction of the city. urban drainage system have greatly developed
their situation is constantly improving. However, due to historical reasons many unpredictable factors in the synthesis of her time, the city drainage system. In particular drainage system often lags behind urban construction. Therefore, there are often good building excavation has been building facilities to upgrade the drainage system phenomenon. It brought to the city sewage, and it is clear to the city sewage and drainage culvert in the sewage treatment system. comfort is very important to people's lives. Mobile robots designed to clear the drainage culvert and the automatic control system Free sewage culvert clear guarantee robot, the robot is designed to clear the culvert sewage to the core. Control System is the ponent of the development of ultrasonic range finder. Therefore, it is very important to design a good ultrasonic range finder.
2. A principle of ultrasonic distance measurement
