Problems solved by technology
In the actual operation process, the main reasons that affect the stability of meter reading are: (1) The technology of the energy meter suppliers is uneven, and the design schemes of the energy meters of each manufacturer are different, which will make the hardware characteristics of the energy meter of each manufacturer different. Different and there are differences in software functions, which leads to the phenomenon that the acquisition equipment is prone to fail to read or read unstable when collecting different types of electric energy meters, which affects the stability of meter reading
(2) At present, the construction of electricity consumption information system for power users is accelerating, and there are a large number of meter rotations and newly installed electric energy meters, resulting in inconsistent relationships between collection equipment, master station files and on-site electric energy meters, resulting in unstable copy rate
However, this method has a long period and seriously affects work efficiency.

The invention relates to a method for improving meter reading stability of a power utilization information acquisition system. The method comprises automatic identification process and automatic maintaining process, wherein in the automatic identification process, electric energy meters produced by different manufacturers can be fast and successfully identified with fewer steps and simple flow, and communication successful rate is improved, so that meter reading stability is effectively improved; in the automatic maintaining process, electric energy meter files can be effectively and automatically maintained, free maintenance of the electric energy meter files is achieved, meter reading stability is further improved, robustness of the power utilization information acquisition system is improved, and operation cost is reduced.
Description
technical field [0001] The invention relates to a method for improving the meter reading stability of an electricity consumption information collection system, which is applied to the field of electricity consumption information collection for power users. Background technique [0002] In the electricity consumption information collection system of power users, one of the basic functions of the collection equipment is meter reading, that is, the collection equipment collects and saves the data of the electric energy meter through the communication medium (RS485, power line carrier, micro-power wireless, etc.). [0003] In order to ensure the normal operation of the power company, it is usually required that the acquisition equipment can maintain good meter reading stability or copy rate stability. In the actual operation process, the main reasons that affect the stability of meter reading are: (1) The technology of the energy meter suppliers is uneven, and the design schemes...
