【摘要】 本文致力于远程监控系统的研究。在全面、细致地分析了远程监控系统的发展趋势、可靠性的基础上，根据远程监控的特点及发展趋势，提出了一种以数字信号处理器(Digital Signal Processing，简称DSP)为核心，以控制器局部网(CAN-Controller Area Network)现场总线为基础组建远程监控系统的方案，并对该方案的选取、系统各部分的硬件和软件实现、整个系统的可靠性、抗干扰性以及设备故障诊断等问题进行了系统、深入的研究。 充分利用了DSP的高速数学运算能力和丰富的硬件和软件资源，建立了以DSP为核心的控制系统。在系统中实现对高达九路模拟信号的数字采集和处理；通过CAN总线通信系统对多达110路现场设备进行实时监控，通过DSP串行端口对现场设备进行故障诊断和管理，将DSP实时数据采集、CAN总线监控、远程通信有机集于一体，协调工作进行了研究和实现，着重研究了DSP作为微控制器实现CAN现场总线的方法，研究和实现了DSP对调制解调器的控制，和通过调制解调器与远程计算机串行数据通信的方法；对使用DSP汇编语言进行模块化、层次化编程进行了研究和尝试，同时对神经网络在设备故障诊断智能专家系统中的应用做了深入的理论研究。更多还原

【Abstract】 Based on overall and detailed analysis of developing tendency and reliability,systematical discussion to the Remote Monitoring System,this dissertation focuses on the research of Remote Monitoring System. It gives a method to constitute Remote Monitoring System,which is on the base of Controller Area Network (CAN),and its hardcore is Digital Signal Processing (DSP). The choosing of the method,the realization of hardware and software,the reliability and anti-jamming characteristic of the whole system,and fault diagnosis are also proposed.This dissertation presents a kind of control system based on DSP. The system can sample and process nine sets of analog. By CAN Bus,the system can supervise more than 110 sets of equipment in real time;by DSP,fault diagnosis to equipment,real-time data sampling and remote monitoring are integrated into an entire system. The dissertation especially studies micro-controller of DSP that carries CAN Bus into practice and accomplishes interface between DSP and CAN Bus. The dissertation studies how DSP controls MODEM and serial communication with remote computer;it also concerns assemble language programming and neural network in FDD (Fault Diagnosis and Detection).更多还原
