Method for improving communication success rate of NB-IOT single lamp controller

Abstract

The invention provides a method for improving the communication success rate of a NB-IOT single lamp controller and relates to the technical field of a single lamp control system with NB-IOT (narrowband IOT) communication. Due to the narrowband nature of the NB-IOT communication, the requirements of grid connection and line access at the same time when a streetlight is turned on are not satisfied.According to the invention, in the process of the mass sending of communication commands by monitoring platform software, the peak shifting processing such as different batches, different times and hopping is used, and the communication success rate is improved with the combination of a heartbeat response mechanism. When the monitoring platform software performs the mass sending of the communication commands to a single lamp controller of a same road segment, at the same time, a command sequence to be subjected to mass sending is broken into a plurality of sub-sequences of a small number of sizes, the sub-sequences are transmitted in batches, and the limitation of the processing ability of a NB base station is avoided. When the monitoring platform software receives a heartbeat packet of aNB-IOT single-lamp controller, the monitoring platform software actively performs the command issuing operations including condition query, parameter query, parameter modification and lamp switchingcontrol. According to the invention, the communication success rate of the NB-IOT single-lamp controller is greatly improved without increasing the deployment number of NB base stations.

Description

technical field [0001] The present invention relates to the technical field of a single lamp control system for outdoor lighting, in particular to the technical field of a single lamp control system using NB-IoT communication. Background technique [0002] At present, the street lamp management in many cities adopts a single lamp control system, which further improves the level of scientific and refined management, and achieves the purpose of energy saving and emission reduction. NB-IoT narrow-band Internet of Things, as a new Internet of Things communication technology vigorously promoted by operators, has also been applied in single-light control systems. [0003] However, the application of NB-IoT technology to the occasion of single-light control still has the following problems: 1) The network communication of the single-light controller installed on the street light requires high concurrency and low delay, but the NB-IoT technology design The original intention is t...

Problems solved by technology

[0003] However, the application of NB-IoT technology to the occasion of single-light control still has the following problems: 1) The network communication of the single-light controller installed on the street light requires high concurrency and low delay, but the NB-IoT technology design The original intention is to apply to the application scenarios with low communication frequency and small data volume, such as remote meter reading, manhole cover anti-theft, etc.

Due to the bandwidth limitation of NB base stations, high concurrency will lead to communication congestion of NB base stations, and commands and data cannot be transmitted in a timely and effective manner; 2) The inherent low-power sleep characteristics of NB communication networks will cause problems such as command reception delays or even loss
