A two-dimensional code-based power meter reading system and method thereof

Abstract

A two-dimensional code-based power meter reading system and method thereof, including multiple electric meters, multiple concentrators with communication functions, multiple portable mobile terminals, and a background service control terminal, each electric meter is used for power metering, and the metering The data is converted into two-dimensional code labels, the signal output terminals of the electric meters are connected to the corresponding concentrators, and the signal output terminals of each concentrator are respectively connected wirelessly to the background service control terminal to send the two-dimensional code labels of each electric meter. The electric meter obtains the two-dimensional code label, each portable mobile terminal is wirelessly connected to the background service control terminal, and sends the two-dimensional code label of the electric meter, and the background server control terminal analyzes each two-dimensional code label to read the metering data of each electric meter and stores in the database. The invention provides a new method for intelligent meter reading in electric power systems, successfully develops a remote meter reading technology based on two-dimensional codes, and provides a systematic research and development platform for advanced metering of new intelligent grids.

Description

technical field [0001] The invention relates to the field of electric meter reading, in particular to a meter reading method based on a two-dimensional code. Background technique [0002] In May 2009, the State Grid released the research report "Building a Strong Smart Grid" and put forward the connotation of developing a strong smart grid. The highly integrated integration of "flow, information flow, and business flow" is a modern power grid that is strong, reliable, cost-effective, transparent, open, and friendly. A unified strong smart grid featuring informatization, digitization, automation, and interaction. [0003] Relatively speaking, the current domestic electricity meter reading methods mainly include remote wireless meter reading, infrared meter reading, manual meter reading, etc. This method has the following defects: 1. The response is not timely. 2. Resource scheduling is unreasonable and resources are wasted. 3. The meter reading cycle is long. 4. The commu...
