The invention discloses an intelligent electric meter terminal positioning method and system. The method and system are used for positioning intelligent electric meter terminals in an intelligent power grid. The method includes the following steps: an intelligent electric meter terminal sends a Chirp signal; multiple intelligent power grid gateways receive the Chirp signal sent by the intelligentelectric meter terminal, and each intelligent power grid gateway reproduces the received Chirp signal according to information of the received Chirp signal and jointly sends the reproduced Chirp signal and processing delay information of the Chirp signal by the intelligent power grid gateways to the intelligent electric meter terminal; the intelligent electric meter terminal calculates the distance between self and each intelligent power grid gateway according to the information of the received Chirp signal and the processing delay information after receiving the Chirp signal returned by eachintelligent power grid gateway; and the intelligent electric meter terminal calculates the own position according to the distances and the position of each intelligent power grid gateway. The method and system are lower in cost and higher in positioning reliability and accuracy.
Description
technical field [0001] The invention relates to the field of smart grids, in particular to a smart meter terminal positioning method and system. Background technique [0002] In the power grid, it is usually necessary to locate the terminals of the electric meter. For example, when an electric meter fails, the location information of the electric meter terminal can help maintenance personnel find the specific location of the faulty electric meter in time for emergency repairs, effectively improving work efficiency. For another example, when the power company conducts statistics on fixed assets, it can conveniently make statistics on the electric meter terminal according to the location information of the electric meter terminal, and it is also helpful to obtain the relevant information of the electric meter terminal lost due to special circumstances. [0003] At present, in the smart grid, the positioning scheme mainly includes satellite positioning, RSSI (received signal s...
