ABSTRACT
Greenhouses are a form of protection to create crop growth and a development environment under artificial control. Modern agricultural greenhouses can generally be divided into two categories: glass greenhouses and plastic greenhouses. Glass greenhouses have a metal or wooden frame, covered with glass. Plastic greenhouses are covered with plastic film or plastic plates (including reinforced plastic board, glass steel, etc.) (Yang et al., 2006). Glass greenhouses represent the universal application of the modern greenhouse, so the intelligent agricultural greenhouse control system is mainly designed for the well-known Venlo glass greenhouse.
