摘要
针对目前人工抄表存在的种种缺陷,提出了一种结合GPRS技术、LPC2294高效微处理器和μC/OS-II嵌入式实时系统,采用目前流行的嵌入式代码组件化技术研制出一种低功耗、高性能、强实时、构件化的无线自动抄表系统方案。在硬件方面主要介绍了GPRS数据通讯技术和CS5460A计量芯片的应用;软件方面主要讲述基于μC/OS-II操作系统组件化移植方法和WINDOWS系统COM组件服务技术。由于具备了低功耗、速度快、数据吞吐量大等优点,本系统具有良好的市场前景。
Focused on the shortcomings of current automatic reading meter systems, present a solution based on GPRS technology, efficient microprocessors LPC2294 and μC/OS-II embedded real-time systems, using the popular embedded component technology, developed a low-power, high-performance, strong real-time and component model wireless automatic meter reading system. In the aspect of hardware, introduced the GPRS data communication technology and the application of CS5460A. In the aspect of software, described component of source code design methods based on μC/OS-II and component object model services technology of Windows. With features of a low power,rapid transmission, big throughput, this system has a bright future.
