Abstract:

LED can effectively release the light of a specific wavelength to promote the plant photosynthesis. However, the plant growth lights mostly used on the market are lack of systematic control, which generally have the disadvantage of high cost, low reliability and low flexibility.In order to solve these problems, a set of intelligent LED control system for promoting plant growth is developed. The system uses a centralized and distributed architecture, which can greatly expand the control range and optimize the system's response capability. In particular, the multi-communication mode used in system integrates a variety of data transmission mode, which includes various kinds of remote communications and local area network communications. In this way, it will greatly improve the flexibility and reliability of the control system. In the multi-communication mode,the control device is embedded with a configurable priority list and centralized controller completes the real-time detection to dynamically select the steady communication mode with high priority.In the local area wireless network communication,a set of network strategy with the function of self-maintenance and self-healing is proposed, which greatly improves the reliability of the wireless network. Finally, an actual test has been carried on and the result is good. The control system with the characteristics of high reliability and high flexibility can adapt to various kinds of agricultural field conditions .It will have good market potential.
