摘要
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.关键词
