In order to monitor and analyze quantitatively the important performance parameters of a system in operation during full process and satisfy the operation requirements under special operation environments such as high pressure impact, a measurement and storage system design method is proposed based on field-programmable gate array (FPGA) and Flash dielectric. The circuits and operation principles of the modules in hardware system are described in detail. The corresponding timing sequence logic of digital circuits in the system is given. The methods for encoding in collection and for improving storage speed are introduced. The accurate and reliable design requirements in operation are achieved. And detailed basis is provided for analyzing the operation states of the device based on the recorded data.
