In the construction of the power Internet of Things, the active reporting of power meter outage events was listed as a special pilot project. Based on the further study of residential users' power consumption information collection system, this paper presents the active reporting technology of power meter outage based on broadband power line communications, using the world's first IEEE1901.1 standard middle frequency band in the power line communication chip, design the hardware of the broadband power line communication module, software flow and communication protocol. The test results show that the broadband power line communication technology can fully meet the demand of active reporting of power meter outage in the power Internet of things.
