Embodiment Construction

[0025] With reference to accompanying drawing, further illustrate the present invention:

[0026] An automatic meter search method for a smart grid, comprising the following steps:

[0027] 1) Obtain and store the addresses of all residents' electricity meters;

[0028] 2) Start the search and initialize the table search information;

[0029] 3) All address bits are replaced by wildcard A for meter reading, to determine whether there is data received on the transmission bus:

[0030] (3.1), if no data is received on the transmission bus, it is considered that the device installed with the automatic meter search program is not connected to any electric energy meter, and the meter search process is directly ended;

[0031] (3.2) If a complete thermal insulation is received on the transmission bus, it means that there is an electric energy meter directly under the device, and the meter search process is ended after uploading the information of the electric energy meter;

Abstract

The invention relates to an automatic meter searching method for an intelligent power grid, which comprises the following steps of: acquiring and storing addresses of electric meters of all residents; starting to search and initializing meter searching information; replacing all the addresses with a wildcard character A to carry out meter reading and judging whether data is received on a transmission bus or not; and sequentially sending out meter reading commands and sequentially determining the addresses of the electric energy meters from the lowest level to the highest level. The automatic meter searching method for the intelligent power grid has the advantages that the accuracy of the information of the electric meters of the residents can be ensured; the automatic meter searching method for the intelligent power grid is convenient and rapid; and additional cost does not need to be added.

Description

technical field [0001] The invention relates to an automatic table search method for a smart grid. technical background [0002] At present, the national grid is in a period of rapid development, and the country has also put forward the requirements of smart grid, and an important content of smart grid is the smart meter reading system. The remote meter reading function of the main station is realized, which greatly enhances the real-time performance, reliability and convenience of meter reading. [0003] To realize the reliable operation of the above-mentioned system, an important prerequisite is to add the information of residents' electricity meters to the archives of the concentrator. However, at present, the information of residents' electricity meters is manually added to the file, and the information is prone to errors. Once there is an error in the information, the electricity consumption information of the resident’s electricity meter cannot be read back. accurac...
