Abstract
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 core
component of the development of ultrasonic range finder. Therefore, it is very important
to design a good ultrasonic range finder.
At the core of the design using AT89C51 low-cost, high accuracy, Micro figures
show that the ultrasonic range finder hardware and software design methods. Modular
design of the whole circuit from the main program, pre subroutine fired subroutine
receive subroutine. display subroutine modules form. SCM comprehensive analysis of
the probe signal processing, and the ultrasonic range finder function. On the basis of the
overall system design, hardware and software by the end of each module.
The research has led to the discovery that the software and hardware designing is
justified, the anti-disturbance competence is powerful and the real-time capability is
satisfactory and by extension and upgrade, this system can resolve the problem of the
car availably, building construction the position of the workplace and some industries
spot supervision.
