Abstract
With the development of industrial and agricultural, Multi-channel data acquisition is bound to be more and more applications. To adapt to this trend, researching in this area is important. In scientific research, we will get a lot of dynamic information by using the data acquisition system. As well as access to scientific data and knowledge generated, it is one of the important means. In short, Regardless of which application in the field, Data acquisition and processing will have a direct impact on the efficiency and cost-effectiveness of the work.
The graduation design is the design of the data processing module of remote data acquisition termination, which is about the basic research of the multi-channel data acquisition system. The system is to solve the problem of the real-time data acquisition and multi-channel data processing. Contain of AD574A and 8051 as the core, the system has two part of the data acquisition and data processing .The system include the simulation of multi-channel switch, MCU and ADC materially. The system do 16 routes data acquisition by using two AD4501, and then the data are sent to the AD475A. After A/D conversion, the data are sent to MCU by Parallel transmission. The hardware was designed by using electronic design automation tools, then the software was designed by using the modular Programming.
