Application of FPGA in pressure measuring system with temperature compensation

介绍一种基于FPGA带温度补偿设计的气压测量系统,详细论述了FPGA处理器在气压测量系统设计中各功能部分的内部设计结构、工作流程以及补偿算法的分析和设计,最后通过系统测试结果验证FPGA设计对气压测量系统中温度补偿的可行性和有效性。由于FPGA具有高可靠性、强数据处理能力、速度快等特点,有效地改善了一般气压测量系统精度低、处理速度较慢、实时性较差的问题。

From the analysis of the characteristics of FPGA processor, This paper introduces the structure of pressure measure-ment system with temperature compensation design based on the FPGA, discusses in detail the FPGA processor design of the func-tional part of the internal design structure, work flow and compensation algorithm analysis and design in the pressure measurement system ,finally the system test results validate the design on FPGA in pressure measurement system with temperature compensation is feasible and effective. Because FPGA processors has the high reliability, strong data processing ability, speed and so on, effectively improved the general pressure measurement system accuracy is low, the processing speed is slow, lack of real time problem.
