Abstract
The water resources has become China's current and future development of the
important resource,It has important significance for the rational utilization of water
resources. In many places of our country need to water level monitoring, such as plant
reservoir, reservoirs, irrigation water level and so on, therefore the use of modern means
of communication to measure and control the water resources as well as the use of
computer management system to realize the acquisition and monitoring of data level
monitoring in field level, and water level data storage, in the water level information
management platform display, query and so on, is an important means to realize the
scientific management of water resources. This paper from the economic and reliability
point of view, on the basis of experiment, a device which can realize automatic water level
control is designed.
Control system of single chip microcomputer technology with its small size, high
reliability and is widely used in. The paper analyzes the design of the measurement and
control system. First of all, the performance and the development of the design used in
the single chip microcomputer is introduced briefly; principle of the ultrasonic sensor to do
a simple analysis, the system uses the analog-to-digital conversion chip ADC0809 haalso
made the simple description of properties.
Secondly, the paper focuses on the measurement and control hardware composition,
software for the breakdown, modular design analysis phase. On the part of the circuit one
one is introduced, the final realization of the system hardware circuit. Drawing the circuit
