Abstract

The embodiment of the present invention provides a meter reading method and a data collector based on power line communication. The meter reading method includes: the data collector obtains communication time information, and the communication time information includes the communicable time of the electric meter, and the communicable time is a predetermined time when the electric meter can successfully communicate with the electric meter; The target communication time is determined according to the communicable time; the data collector communicates with the electric meter to read the meter at the target communication time. In the embodiment of the present invention, by determining the target communication time according to the predetermined communicable time that can successfully communicate with the electric meter, and communicating with the electric meter for meter reading at the target communication time, it is possible to avoid peak power consumption, thereby improving reading efficiency. Table success rate.

Description

technical field [0001] The invention relates to the field of power communication, in particular to a meter reading method and a data collector based on power line communication. Background technique [0002] Power line communication (PLC for short) refers to a technology that uses existing power lines to transmit analog or digital signals at high speed through carrier waves. PLC is currently widely used in smart grids adopting Advanced Metering Infrastructure (AMI) to realize remote automatic management of electric meters and collection of electric meter data. However, in the power line communication system, when the power line is disturbed by noise or the load is heavy, normal communication will be affected, resulting in a low communication success rate. Contents of the invention [0003] The application provides a meter reading method and a data collector based on power line communication, which can improve the success rate of meter reading. [0004] In the first aspec...
