基于多传感器融合的压力测量系统设计

当今，所有以微处理器为基础的测控系统都需要传感器来提供做出实时决策的数据。本文详细阐述了压力传感器测量系统硬件设计、压力传感器智能化软件设计、压力传感器误差与温度补偿技术设计。针对传感器测量的温度漂移和非线性等问题，提出了利用多传感器信息融合技术--曲面拟合法和曲线拟合法来加以解决，并实现PC机与传感器测量系统之间的通信，完成数据转换、数据处理和打印等功能，使测量系统更加完善。

Design of Pressure Measurement System based on Multi-sensor Technology

At present, all the control system based on the microprocessor need the sensor to supply real-time data. The author detailed expatiated on the hardware design of measurement system and software design of intelligent. We put forward a scheme that multisensor data fusion-surface fitting and curve-fitting was applied in this system according to the temperature drift and nonlinear of sensor. Communication between personal computer and measurement system of sensor was realized by means of transceiver, which could finish the data conversion, data processing and printing task, with the result that the measurement system was further improved.
