Integrated controller for intelligent street lamp

Abstract

The invention relates to an integrated controller for an intelligent street lamp. The integrated controller communicates with a server through any one of a 4G communication module, a WiFi communication module, a ZigBee communication module and an Ethernet communication module. Six relay output interfaces, a PLC power carrier interface, a three-phase ammeter and six digital quantity acquisition interfaces are arranged in the integrated controller; a RS485 interface is connected with a plurality of external relays, a plurality of external electricity meters, a plurality of external digital quantity acquisition modules and a plurality of external illuminance meters; a PLC power line carrier interface is connected with a PLC single lamp controller and is used for managing and controlling the PLC single lamp controller; and the MCU is connected with a man-machine interaction interface. Ethernet communication, 4G communication and WiFi communication can be selected as the communication modes of the integrated controller and the server; through expansion of an external relay, 60 relay loops can be expanded at most; at most 512 PLC single lamp controllers can be managed and controlled; and electrical parameters of at most 30 loops can be acquired.

Description

technical field [0001] The invention belongs to the technical field of street lamp control, in particular to a centralized controller for smart street lamps. Background technique [0002] With the development of the city, the urban road lighting system is increasingly showing its importance in urban construction, especially with the advancement and construction of smart cities, street lighting is also very suitable to become the carrier of smart city infrastructure , but with the continuous expansion and complexity of the construction of the street lighting system, the existing system will be overloaded. Apply centralized controller, can control the switch of multiple loops, can automatically open or close one or several loops according to the predetermined strategy; can collect the electrical parameters of each loop; can collect multiple digital signals; can collect illuminance values ; And part of the background work of the system can be handed over to the centralized con...

AI Technical Summary

Problems solved by technology

[0003] The existing central controller has a single communication mode, including only 4G or Ethernet, or ZigBee; the number of controllable loops is limited, generally only 6 loops; the number of digital channels that can be collected is limited, generally 6 to 8; manageable, There are also fewer PLC single lamp controllers controlled, generally about 200
