Intelligent plant factory production run requires not only environmental factor control, fertilizer supply and deployment of control automation, also need to automate operations in the nursery, transplanting, harvesting and other production processes, reducing anthropogenic interference with the production of space pollution. Plant plant operation and production of intelligent management and control need to consume energy.
Artificial light energy plant factory constitutes includes a light source, air conditioning, pump-action systems, pneumatic systems, measurement and control systems. Plant Factory on artificial light, the energy consumption is the largest lighting system, more than 60% of total energy consumption; followed by air-conditioning systems, accounting for more than 30%, the rest of management and control systems are relatively less energy consumption. Currently, the cost of energy consumption has become the main form of plant plant operation costs is an important reason for the high cost of running the plant factory. Therefore, to reduce the energy consumption of lighting systems, has become the main way to plant the plant energy efficiency.
Light-emitting diode (Light-emitting diode, LED) is a semiconductor solid-state light source is a fluorescent lamp and other traditional sources of plant factories ideal alternative, energy-saving effect is obvious. As importantly, the development of LED semiconductor lighting technology for plant factory energy sources and environmental intelligent control provides hardware conditions, the maximum energy saving potential is to achieve a light quality, intelligent control of light intensity and photoperiod. Meanwhile, light as an effective environmental factors regulating plant growth and development and yield and quality formation, light environment is crucial to improve the regulation of artificial light plant factory production efficiency. Currently, the plant factory there is a high energy LED light source, the light energy utilization is low, the lack of light environment precise control technology and other outstanding issues, to carry out major horticultural crops plant plant optimization parameter control mode light environment research is to reduce the energy consumption of LED lighting systems, increasing productivity only way.
