A Micro-Computer Controlling and Data Processing System for Fiber-optic Pressure Sensor

本文介绍的光纤压力传感器微机控制与数据处理系统是以8098单片机为核心,配上适量的外围电路所构成。该系统直接利用8098单片机芯片内的A/D模拟输入通道和脉宽调制(PWM)功能来进行数据采集和输出控制信号。该系统还方便地实现与微型打印机的联接,以便将采集的数据保存。整个系统结构简单,成本低,可靠性高,实时控制和测试功能较强,有良好的工业应用价值。

This paper presents a micro-computer controlling and data processing system which consists of a 8098 single-chip computer and some peripheral circuits for fiber-optic pressure sensor. The input channel of A/D and the signal of pulse width modulation in the 8098 were used for data acquisition and control sig- nal output. The system is connected conveniently with the micro-printer, so that the collected data are pre- served. The system is simple in structure, low cost, high reliablity, real-time control and more functions, so it has good applications in the industry.
