Intelligent street lamp control module and intelligent street lamp control system

Abstract

The invention provides an intelligent street lamp control module and an intelligent street lamp control system. The intelligent street lamp control module comprises a power line carrier communication module, a network switch, a sensor data acquisition module, a dimming controller and a single chip microcomputer, wherein the single chip microcomputer is connected with the sensor data acquisition interface through a serial port; the power line carrier communication module is connected with the single chip microcomputer through a serial port; the network switch is connected with the power line carrier communication module through a serial port; the dimming controller is connected with the single chip microcomputer through a serial port; and the single chip microcomputer is used for realizing communication and control on the above power line carrier communication module, the network switch, the sensor data acquisition interface and the dimming controller. According to the intelligent street lamp control module to building a high-bandwidth communication network based on the power line, the bandwidth of a PLC communication scheme can be greatly improved. Besides, the system also realizes remote on and off of the street lamp, sensor data acquisition, video monitoring and transmission and electronic advertisement content pushing and displaying.

Description

technical field [0001] The invention relates to the field of the Internet of Things and lighting, and in particular to an intelligent street lamp system and an implementation method. Background technique [0002] The smart street lighting system in the prior art generally includes three modules: [0003] The street lamp control module is used to complete the intelligent control of street lamps and complete the data collection functions such as sensors; [0004] Centralized controller, on the one hand, it can manage the single lamp control module, on the other hand, it can interact with the platform remotely; [0005] Platform data service center to manage street light control modules and centralized controllers, [0006] The single lamp control modules on the market generally adopt narrowband PLC (power line), Zigbee (wireless) and other transmission modes, and realize remote interaction with the platform data service center through the centralized controller. Both PLC an...

AI Technical Summary

Problems solved by technology

Both PLC and Zigbee communication modes have the disadvantage of low bandwidth (usually around tens of Kb, which can only be used to realize remote switching of street lamps, sensor data collection and other small data transmission), which cannot meet the needs of more scenarios. Rich application requirements, such as the application scenarios where street lights are installed with terminals such as video surveillance, broadcasting, and electronic advertising screens

[0007] In the existing solutions, optical fiber or twisted pair communication is used to solve high bandwidth requirements. The disadvantage of this is that it will lead to a double increase in system cost and cost.

If the street light control adopts PLC or zigbee, it can only use low-bandwidth data, and the application scenario is single and the efficiency is low

If high-bandwidth data uses optical fiber / network switches, street light control cannot be realized

If wifi bridge is used, the actual effect is poor and cannot meet the application requirements
