Description
technical field [0001] The invention relates to a real-time point-to-point electric energy meter centralized meter reading system based on Ethernet, and belongs to the technical field of a new structure of a meter reading technical device for a power supply enterprise. Background technique [0002] At present, the traditional energy meter centralized reading technology is mainly composed of a meter reading master station, a collector, a concentrator, and an energy meter. It uses carrier, wireless or wired communication, or a combination of multiple methods. For example, the collector and the energy meter use a 485 interface. To connect, the carrier is used between the collector and the concentrator, and then the concentrator communicates with the meter reading master station through GPRS. This kind of meter reading technology has many nodes, and the data is processed and converted by multiple devices. The operation and maintenance of the equipment is complicated and the work...
