With the rapid development of the Internet of Things, information technology and computer technology, urban lighting from the traditional lighting towards automation and intelligence, in recent years we often hear the intelligent light pole is one of the applications of intelligent lighting. Speaking of intelligent light pole, we have to mention is its intelligent lighting control system. Compared with traditional lighting, intelligent lighting pole intelligent lighting has a safe and stretchable, feature-rich, energy-saving and emission reduction effects. Among them, the application of intelligent lighting control system plays a key role in the realization of remote control of lighting equipment – intelligent light pole switch, brightness adjustment lamp function. This article will focus on the structure and composition of the intelligent lighting control system to continue to talk about those things of the intelligent light pole.
In general, intelligent lighting control systems are digital lighting management systems, consisting of system units, input units and output units, which are composed of several parts. In addition to the power supply equipment, each unit has set a unique unit address, and set its function with software.
Used to provide working power, source system clock and various system interfaces, including system power, various interfaces (PC, Ethernet, telephone, etc.), network bridge. The main system implements the same network of control and signal sampling for each area; the subsystem implements a network of different specific controls for each partition. The main system and the subsystem are connected to each other by components such as messages for data transmission.
Used to transform external control signals into signals transmitted on the network; such as programmable multi-function (on / off, dimming, timing, soft start / soft off, etc.) input switches, infrared receiving switches and infrared remote control (to achieve lighting dimming or on / off function). Various types and multi-functional control board, (such as the provision of LCD page display and control mode, and graphics, text, pictures to do soft keys, multi-point control, timing control, storage of a variety of bright mode, etc.), a variety of functional sensors (such as infrared sensors can sense human activity to control the switch of the lamps or other loads, brightness sensor), through the detection of the brightness of the surrounding environment, adjust the Through the detection of the brightness of the surrounding environment, the brightness of the light source, so that the surrounding environment to maintain the appropriate illumination, in order to achieve the effective use of natural light, saving electricity.
The output unit of intelligent light pole control system is used to accept the signal transmitted from the network and control the output of the corresponding circuit to achieve real-time control. The output unit has various types of relays. Dimmer (to adjust the load current object, in addition to dimming function, can also be used as a soft start, soft shutdown of lamps and lanterns) analog output unit, lighting dimming interface, infrared output module, etc..
The system generally adopts the way of centralized control and management, decentralized execution, that is, the configuration of the central monitoring center and intelligent control lighting cabinet, the former has control computer, main communication controller and other equipment for the control and management of the whole system, through the network will control the command and the intelligent control cabinet of the programmable controller for communication, while receiving from the intelligent control cabinet of the programmable controller about automatic and manual working status, lighting on/off status, etc., and take processing measures under abnormal conditions.
