Design And Implementation Of High Energy Efficient Wireless Data Acquisition System

The data acquisition system is widely applied in the scientific research and the industrial production,and it plays the important role in raising in the people working efficiency and the plant production efficiency.The traditional data acquisition system's design often pursued the sampling speed and the sampling precision.But along with time development and society's progress,people start to pay attention to data acquisition system's power,communication and storage capacity.Based on such background,this thesis designed and realized the high energy efficiency wireless data acquisition system.The system optimizes the system's power consumption,and expand the system's data storage capacity and uses wireless communication technology for data transmission.This thesis will introduce the high energy efficiency wireless data acquisition system's software and hardware design and low power loss design of the system in detail.According to technical requirement,this paper first discusses the general structure and the design of data path, and demonstrates the feasibility in theory.Then the system hardware platform which using FPGA+MCU dual processors are described.This thesis will introduce software design of system from MCU to FPGA dual processors,In the part of MCU,the thesis will give the software design of man-machine interaction,the design of file system for data storaging and the communication protocol between FPGA and the MCU.In the part of FPGA,the thesis will describe the function and the logic design of each module within the FPGA design in detail.In low power design,this thesis analyzed the power consumption of the system in detail at first,and unifies the current popular low power loss design technique and system's characteristic to designs system high energy efficiency operation plan and test this plan.In the end,the thesis analysis the testing result of system's function,and gave the improvement comment.The result verify the rationality of the hardware platform and the feasibility of the software and provide foundation for research better high energy efficient wireless data acquisition system.
