【摘要】 介绍了仪表总线M-BUS的发展与应用,论述了其通信中的接收、发送机制,在此基础上提出了仪表总线主机、从机嵌入式接口的软、硬件设计方案。在从机设计中采用接触式CPU智能卡实现计费管理,微处理器采用低电压、低功耗、高速度MSP430系列单片机。实际运行表明:所设计的主机接口传输距离远,带载能力强;从机接口功耗小、可靠性高、抗干扰能力强。更多还原

【Abstract】 The development and application of the M-BUS were introduced,and mechanism of transceiver was discussed.As the main content,the hardware and software design of host and slave embedded interfaces were researched deeply.While IC card was adopted to operate tariff manegement,slave interface uses MSP430 as microprocessor.As the application shows,the above host interface designment lengthens communication distance and strengthens the loading ability;the slave interface,improving precision and anti-jamming ability.更多还原
