Communication island solving method based on high-speed power line carrier and LORA technology

Abstract

The invention relates to the field of carrier communication technology application, in particular to a method for coping with a communication difficulty scene in the field of intelligent power grid centralized meter reading application, and particularly relates to a method for solving a communication island problem based on a high-speed power carrier communication and LORA technology. Data transmission is completed, and the actual problems of 'last kilometer' and related 'communication island' are solved; According to the method, wireless modules of different schemes can be replaced accordingto actual problems on site, maintenance is convenient, applicability is higher, data acquisition requirements of users are well met, the user experience is effectively enhanced, and the method has high social application value.

Description

technical field [0001] The invention relates to the application field of carrier communication technology, and is a method for coping with difficult communication scenarios in the application field of smart grid centralized copying, in particular to a solution to the communication island problem of high-speed power carrier communication and LORA technology. Background technique [0002] Based on the smart energy meter and network communication technology, the State Grid has started the large-scale construction of the electricity consumption information collection system in 2009, and the power carrier communication technology has been widely used in the national smart grid construction needs due to its low construction cost and easy system maintenance. Especially in the business field of centralized meter reading. With the continuous deepening of the State Grid's new round of electricity information collection system construction in 2018 and the continuous expansion of collec...

Problems solved by technology

[0006] The present invention is mainly used to solve the following problems in carrier communication application scenarios: newly installed high-speed power carrier station area or some area nodes in the process of station area transformation, carrier signal cannot reach or areas where data index assessment is seriously affected due to extremely unstable signals; The reasons for the above phenomenon are: on-site short-term or continuous pulse noise interference; the transmission distance of the line is too long; the signal attenuation caused by the ground cable is serious, etc.
