【摘要】：随着社会的进步和新技术的发展，工业监控的模式和范围正在发生着深刻的变化。传统上局限于较小地理范围的工业监控手段，已越来越难以满足工业用户自动化生产和设备厂商提供高质量售后服务的需求。当前，无线通讯技术的发展使得手机网络可以覆盖全球，嵌入式系统的发展使仪器仪表拥有良好的计算平台。将手机网络与嵌入式系统有机结合起来，可以大大提高工业监控的水平，扩展工业监控系统覆盖的地理范围。由于工业监控系统的实时性要求通常比较高，而Nucleus具有实时响应、抢先、多任务、外部接口清晰以及源代码开放等特点，因此本文采用Nucleus实时操作系统，以广泛应用的MTK手机系统为硬件基础，设计并实现基于二者结合的工业监控实时系统。本文的主要工作及成果主要包括以下几个方面：1）对Nucleus系统的体系结构进行了介绍，对该系统的实时性能进行了深入分析；2）设计并实现了一个函数库，，对监控系统的线程、优先级、中断等的管理，监控系统的数字量、模拟量、控制量、通信等I/O接口的访问进行了统一封装，使得工业自动化系统设计人员可以方便快捷地进行二次开发；3）在MTK手机系统硬件平台上，基于本文所开发的函数库搭建了可进行远程数据采集、故障报警、参数调整、算法分析的实时监控系统。本文通过实际应用验证了所设计的嵌入式平台、软件系统结构，以及数据传输方式的有效性。
[Abstract]:With the progress of society and the development of new technology, the mode and scope of industrial monitoring are undergoing profound changes. It has become increasingly difficult to meet the needs of industrial users to automate production and equipment manufacturers to provide high-quality after-sales service. With the development of embedded system, the instrument has a good computing platform. The combination of mobile phone network and embedded system can greatly improve the level of industrial monitoring and expand the geographical coverage of industrial monitoring system. Because the real-time requirement of industrial monitoring system is usually high, and Nucleus has the characteristics of real-time response, preemption, multi-task, clear external interface and open source code, so this paper adopts Nucleus real-time operating system. Based on the widely used MTK mobile phone system, a real-time industrial monitoring system based on the combination of both is designed and implemented. The main work and achievements of this paper include the following several aspects: 1) the architecture of Nucleus system is introduced, the real-time performance of the system is analyzed deeply and a function library is designed and implemented to monitor the thread of the system. Priority, interrupt management, digital, analog, control, communication, and other I / O interfaces are uniformly encapsulated. On the hardware platform of MTK mobile phone system, based on the function library developed in this paper, remote data acquisition, fault alarm, parameter adjustment are built. Algorithm analysis of real-time monitoring system. The effectiveness of the designed embedded platform, software system structure and data transmission mode is verified by practical application in this paper.
