| 摘 要： | 为满足航天仪器在飞行试验过程中对环境温度变化的测控,提出了一种基于ARM和FPGA的远程温度测控系统,以STM32F103和XC2S200作为控制核心,通过高精度AD采集芯片ADS1148采集温度传感器端的电压信号,通过ADS1148内部放大、转换成数字量信号,再通过SPI接口传输给控制核心STM32F103。为了实现远端控制,能在2.5 km对-160℃~1370℃温度范围的测控,设计了光电转换模块,把采集的数字量信号转换成光信号传输给近端的控制台,实现温度的远程、实时监测。该项目已经在某航天仪器上的应用实践表明,该系统测温范围广、精度高、功耗低、可靠性高。

| Abstract: | In order to meet the requirements of aerospace instruments in flight test,the paper presents a remote temperature measurement and control system based on ARM and FPGA.With STM32F103 and XC2S200 as the control cores,the ADS1148 high-precision AD acquisition chip is used to collect the voltage signal from temperature sensor.The signal is amplified through the ADS1148 internal,converted into digital signals,and then transmitted to the control core STM32F103 through the SPI interface.In order to realize the remote control,the photoelectric conversion module is designed to measure and control the temperature range of-160℃~1370℃2.5 km away.This module converts the collected digital signal into optical signal and transmits it to the near-end console to achieve the goal of remote real-time monitoring temperature.The application of this project in space instrument shows that the system has wide temperature range,high precision,low power consumption and high reliability. |
