The Design of Liquid Level Control System Based on MCU
Abstract
The liquid level measurement is widely used in industry, economy, life and
other fields. This design take the water tank water supply as a model, uses in
carries on the survey to the water tank fluid position signal to monitor the
record。
The liquid level measurement device base on MCU is widely used because of many
characteristics such as high measurement accuracy， good repeatability, low power
consumption and long useful time。 When we study Scientific Outlook on Development
thoroughly， the design of electronic aid should include the thought of sustainable
development. So， beyond the liquid level measurement device based on MCU， expand the
functions of real—time monitoring， data acquisition， serial communication。 Through
the new functions, the scientific method of the liquid level measurement could be
combined with Statistical Science ， be used to manage the water resources
reasonable, reduce energy consumption。
This thesis introduces the design process of the liquid level control system
by several parts as system schema， the design of hardware circuit， the software of
host computer and system software, ultimately achieved the level of real—time
measurement and monitoring. Finally， the paper summarizes the problems and solutions
of the design process, describes briefly the method of data processing, and leads
to ideas of the further design and development.
