Abstract

The invention discloses a PLC based intelligent lighting system for a plant. The plant lighting involves lighting of a plurality of different areas, and the lighting of the plurality of different areas can be independently controlled through a control system; the control system comprises a PLC, a human-computer interface, a plurality of temperature sensors, a plurality of light-sensitive sensors, a plurality of infrared sensors and a plurality of relays; the temperature sensors, the light sensitive sensors and the infrared sensors are distributed in different areas as requirement and used for respectively the temperature, brightness and parameters signals of people in each area; the output ends are connected to the PLC; each I / O output end of the PLC is connected with a relay; a lamp is connected to the output end of the relay; the PLC is used for receiving the parameter signals and intelligently controlling the lamp in each corresponding area by the internal programming control of the PLC. The system is reasonable in design and can effectively save energy and electricity.

Description

technical field [0001] The invention relates to the field of lighting control, in particular to an intelligent lighting system based on a PLC controller and targeting factories. Background technique [0002] Countries all over the world are taking different ways to save energy and save electricity. With the rapid development of the national economy and the acceleration of urbanization in our country, the power consumption for lighting has increased tremendously in the past ten years, and the problem of power saving for lighting has been listed as another major power saving project besides power saving. Factory lighting occupies a certain proportion of the total industrial electricity consumption in my country. Lighting electricity consumption is the basic power demand of factories and enterprises. The quality of lighting has a direct relationship with production safety, labor productivity, product quality and labor hygiene. Therefore, power saving for factory lighting is a ...
