The invention discloses an industrial production guiding system and method based on a light-emitting diode color array. The system comprises a plurality of light-emitting diode color array RGB-LEDs, an array CCD, a central microprocessor MCU, a production fixing device, a main server, production mobile devices and the like. Each light-emitting diode color array corresponds to one production fixingdevice; the state information of the production fixing device is transmitted back to the MCU through a bus GPIB, the RGB-LED is controlled through real-time coding, data is shared to all terminals inreal time through a MIMO-VLC communication system, and three-dimensional space measurement is achieved through the RGB-LED and the CCD array. According to the invention, the advantages of rich spectrum resources, illumination and communication, greenness, high safety, no electromagnetic interference and the like of visible light communication (VLC) are utilized; based on a pixelated MIMO-VLC optimization method, a spatial three-dimensional industrial production guiding system is built, resources are saved, the data interaction efficiency of an intelligent factory is greatly improved by meansof the advantage of visible light, and the method is safe, reliable, energy-saving, environment-friendly, rapid, efficient and real-time in modeling.
