Dual-mode meter reading technology based on LoRa and carrier waves

Abstract

The invention discloses a dual-mode meter reading technology based on LoRa and carrier waves. The technology comprises a LoRa carrier dual-mode built-in module, a collector, a carrier concentrator, aLoRa base station, a communication management machine and an uplink metering platform which are installed on an electric energy meter, wherein the LoRa carrier dual-mode built-in module and the collector which are installed on the electric energy meter execute tasks after receiving task commands transmitted by the concentrator through power line carriers, and transmit the task commands back to theconcentrator through the power line carriers after task data collection is completed. The dual-mode meter reading technology based on LoRa and carrier waves is advantaged in that through combinationof two channels of LoRa and carrier waves, wireless and wired synchronous communication is achieved, and the communication coverage range is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of meter reading, in particular to a dual-mode meter reading technology based on LoRa and carrier waves. Background technique [0002] In the existing field of remote meter reading, most of them use power line carrier and micro-power wireless as the main communication methods, among which power line carrier communication occupies a dominant position in the field of meter reading, but power carrier is easily affected by grid noise and environmental factors, causing meter reading The success rate is not high, and the number of times is long. Although the single micro-power wireless meter reading method gets rid of the influence of grid noise, it is easily interfered by weather, geographical environment and installation location, resulting in some meters being unable to read. The success rate Large fluctuations. [0003] LoRa wireless technology is an ultra-long-distance wireless transmission scheme based on s...

Although the single micro-power wireless meter reading method gets rid of the influence of grid noise, it is easily interfered by weather, geographical environment and installation location, resulting in some meters being unable to read. The success rate High volatility

[0003] LoRa wireless technology is an ultra-long-distance wireless transmission scheme based on spread spectrum technology. This scheme has changed the previous compromise between transmission distance and power consumption, and provides users with a simple way to achieve long-distance and long battery life. , large-capacity system, and then expand the sensor network. Compared with traditional wireless communication technology, it has the characteristics of high sensitivity, wide coverage, strong anti-interference ability, and low power consumption. However, for some building areas and closed spaces in basements also does not provide good coverage

[0004] According to theoretical analysis and application effects, it is difficult for a single communication technology to get rid of the defects of their respective channels
