The invention discloses a centralized multi-meter reading communication interface converter of self-adapting meter reading. Upstream communication with a concentrator is achieved by an RS-485, power line carrier and micropower wireless communication manner for receiving and responding to a data reading command of the concentrator for a water meter, a gas meter and a heat meter; downstream communication with the corresponding type of the water meter, the gas meter and the heat meter is achieved by an RS-485, M-BUS and LoRa wireless communication manner for forwarding and receiving of the data reading command. The converter contributes to improving data reading compatibility, a success rate and efficiency of a centralized 'water, electricity, gas and heat' multi-meter reading system for different types of meters, and a technical support is provided for further popularizing centralized multi-meter reading and achieving resource sharing of public utility infrastructures.
