4G illuminating street lamp intelligent controller based on Internet-of-things

Abstract

The invention discloses a 4G illuminating street lamp intelligent controller based on Internet-of-things. The 4G illuminating street lamp intelligent controller comprises a main processing board, a switching mode power supply which is connected with the main processing board, a communication module (4G/NB-IoT/Wifi), a single-lamp concentrated management module, an analog signal transmitting moduleand an input/output transmitting motherboard. The main processing board comprises the components of an embedded ARM processor, a programmable logic device (CPLD), a program resetting IC, a clock IC,a storage IC and an A/D converting circuit, a precise operational amplifier circuit, a linear rectification circuit, multiple RS232/RS485/RJ45 communication interfaces, a display screen and an operating button. The 4G illuminating street lamp intelligent controller is based on mobile Internet-of-things technology. A modular structure design is utilized. Plug-and-play is realized. The 4G illuminating street lamp intelligent controller supports communication modes of 4G/NB-IoT/Wifi. The 4G illuminating street lamp intelligent controller realizes intelligent centralized management of an illuminating street lamp facility and realizes scientific management of illuminating power.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to an intelligent controller for 4G lighting street lamps based on the Internet of Things. Background technique [0002] The existing street lamp controller circuit does not have a modular partition structure design, and the circuit units are all on the same circuit board. There is no isolation protection design and independent power supply between the circuits, and effective anti-interference protection design cannot be adopted. The EMC electromagnetic interference is serious. affect the stable operation of the circuit. If any part of the circuit is damaged, it will cause the entire circuit board to fail, thus affecting the normal lighting of the city. When struck by lightning or surge voltage, it is very easy to damage the entire circuit system. [0003] Street light controllers without product structure design also have the following disadvantages: everything is installed in ...

AI Technical Summary

Problems solved by technology

[0003] Street light controllers without product structure design also have the following disadvantages: everything is installed in a sealed case, large in size, poor heat dissipation, mutual interference, input and output lines are connected to the case, there is no standard for line installation, and the connection The wiring is messy, and it will be difficult to disassemble and maintain in the future

However, its wireless communication method has narrow bandwidth and large delay, and faces the risk of being eliminated

At the same time, the invention lacks a single lamp centralized management module, which is not conducive to the centralized management of street lamps
