| 摘 要： | 针对国家电网的电、水、气、热多表集抄,提出了一种自适应的MBUS主机电路,通过调整LDO的反馈电阻来实现对M-BUS总线电平的控制,使用电容来采样、锁存总线电流数值,自动适应外部总线电流的变化,从而完成对从机数据的收发。文中详细阐述了主机电路的收发原理,并结合实际应用的特点,实现了与主控电路的光电隔离。现场应用表明,该电路抗干扰能力强、可靠性高、带负载能力强。

| Abstract: | An adaptive M-BUS master circuit is proposed for the multiple meter collection including water,electric,gas and heat of State Grid.The control of M-BUS level is achieved through adjusting the feedback resistor of LDO.The bus current numerical is saved by use of capacitance sampling to automatically adapt to the change of external bus current,so as to receive and send data from the slaves.In this paper,the principle of the master circuit is described in detail,and the photoelectric isolation of the main control circuit is achieved combing with the characteristics of the practical application.The on-site application shows that the circuit has strong anti-interference ability,high reliability and strong load capacity. |
