本论文研究设计了一款基于MCU的嵌入式应用系统---无线对讲机,包括硬件以及软件设计,有相当的可靠性和低功耗措施。首先探究了无线通信终端对讲机的常用功能、性能指标、工作原理。从工作原理出发,通过现代电子系统设计方法---实时设计,深入行业现状寻找到高性能、低成本、开发环境良好的嵌入式微处理器TMP86C820及主要的功能性器件CMX808A、TB31202、KA8507B、LM386、RT178、KMZ52等,确立完整的具体的方案。在具体的硬件设计实现上,以MCU为中心,分别对各个基于IC的功能模块以信号、控制为联系进行设计。整个电路设计中包括有MCU最小系统设计,人机接口设计,系统电源设计,音频信号处理电路设计,频率合成电路设计及附加的指南针功能电路设计等。在软件设计上,通过主循环模块和任务时序安排模块将各功能模块有机地组织起来共同完成系统需要的功能。在软硬件的设计中都适当考虑了系统的可靠性、低功耗的性能需求,使用了去耦、滤波、隔离、数字滤波等方法。这样系统就是符合性能、可靠性、低功耗、低成本的要求的有竞争力的通信终端设备。最后,从软件柔性角度出发,对系统的新应用形态,无线对讲机应用到医院病房的监护中,针对具体情况给了些看法。
I research and design a embedded system based on TMP86C820 in this papers. I am in the charge of the software and the hardware except for radio part, among that there are much ways for reliability and low power of system. At the beginning, I study the operating principle, performance index and typical function of communication terminal equipment PMR. Real-time design that is a means for electronic system design is introduced after operating principle illustrated. During making specific rounded scheme, I have selected MCU TMP86C820 with high performance, low cost and good development tools, other IC CMX808A, TB31202, KA8507B, LM386, RT178, KMZ52 , etc. On the hardware design side, all function blocks based on IC are designed through the signal and control, on the center MCU. There are minimum MCU system, MMI blocks, system power supply block, audio processing block, frequency synthesized block and electronic compass. On the hardware design side, all function modules fulfill the needed functions of system. The main loop body and task-arrangement module make a connection for other modules. Whole designing, the reliability and low power are be considered, among which uncoupling, filtering, insulating and data filtering are used. so this system meet the challenge of functions, reliability, low power and low cost, which there is competitive power. Lastly, a little thinking for new use of system is showed at software flexibility part.
