Problems solved by technology

But at present, the automatic smart meter reading service under the concentrator is mainly based on narrow-band carrier communication. Due to the limitation of modulation technology and bandwidth, the meter reading method adopted has a slow communication rate, low meter reading efficiency, and poor real-time performance, which cannot meet the needs of smart grid cons

Abstract

The embodiment of the invention discloses a meter reading method, a meter reading device and a meter reading system. The meter reading method comprises the following steps: continuously sending first meter reading commands and second meter reading commands to central coordination device CCO by a concentrator during first meter reading period, wherein the first meter reading commands are used for indicating the CCO to acquire first measurement data of a measuring meter, and the second meter reading commands are used for indicating the CCO to acquire second measurement data of a second measuring meter; and receiving first reporting messages and second reporting messages sent by the CCO, wherein the first reporting messages comprise first metering data and markers of the first measuring meter, and the second reporting messages comprise second metering data and markers of the second metering meter, so that the meter reading efficiency is improved.

Description

technical field [0001] The invention relates to power line communication, in particular to a meter reading method, device and system. Background technique [0002] Power Line Carrier (PLC) is a unique communication method for power systems. Power line carrier communication uses high-voltage power lines (35kV and above voltage levels), medium-voltage power lines (10-35kV voltage levels) or low-voltage distribution lines (380 / 220V subscriber line) as a communication method for information transmission as an information transmission medium. This technology loads the high-frequency signal carrying information onto the power line, uses the power line for data transmission, and then separates the high-frequency signal from the power line through a dedicated power line modulator-demodulator, and transmits it to the terminal equipment. Power line carrier communication can Divided into narrowband carrier communication and broadband carrier communication. Narrowband carrier communi...
