离子迁移谱嵌入式控制系统设计及实现

离子迁移谱探测器控制系统需要完成对离子迁移谱信号,压力、温度和湿度等环境参数的实时读取、分析和处理,并实时监控仪器的运行状态.因此,要求该仪器内部的计算机系统响应速度快、可靠性高.嵌入式计算机PC/104的实时性和稳定性满足了控制系统的快速可靠的要求.本文简要描述了PC/104的基本特点,重点阐述了控制系统的硬件结构设计和软件任务模块设计.提出了以SBS SCM/SDXa模块和ADT600数据采集模块构成的控制系统和数据采集系统.

Design and realization of the embedded control system of IMS

The control system of IMS detector will mainly be used to complete the task of reading,analysis and processing the IMS spectrum and environmental parameters signals,e.g.pressure,temperature and humidity,and real-time supervising the running status of detector.Therefore,the internal computer system is demanded to offer the quick speed of response and extra high reliability.The embedded computer PC/104 with property of real time and stability meets the demands of the IMS control system.This paper presents the design and realization of the embedded operating system of IMS,describes the essential feature of PC/104,and emphatically elaborates on the hardware structural design and software task module frame,puts forwards the PC/104 embedded control system consists of SCM/SDXa CPU module and ADT600 data-collecting module.
