The Design and Implementation of Data Acquisition Circuit Based on C51
Abstract
“The design and implementation of data acquisition circuit based on C51” is the circuit PCB designed and implemented according to data of water situation of modern conservancy industry. At the same time, in order to response to the digital conservancy raised by our country, it makes the conservancy informationization implement, perfect and grow. This paper discusses the basic function of electronic circuit design software-Protle99. It takes this system for example to introduce the development steps of this system one by one: demand analysis, system analysis, system design, system implementation and system maintenance. Demand analysis introduces the design of this system focusing on conservancy industry. It analyses functions of various components and various connections of electronic circuit design in system analysis, as well as the function of completion. In the design of this system, it shows the preparing steps of every functional module, drawing of principle chart, and completion of PBC of this system. In the implementation of this system, it gives a complete PBC matched for the function of the system. After repeated tests, the result is that the design of this system is successful and it can be applied to all conservancy industries to collect data.
