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
thatthesoftwareandhardwaredesigningisjustified, theanti-disturbance
competence is powerful and the real-time capability is satisfactoryand
byextension and upgrade, this system can resolve the problem of the car
availably, building construction the position of the workplace and some
industries spot supervision.
