Flower Intelligent Greenhouse System And Its Key Technology Research

With the improvement of the standard of living,people are gradually concerned about how to improve the quality of life.Due to the influence of environmental pollution in recent years,people pay more attention to environmental changes.With the deepening of the Green concept,indoor flowers gradually come into people's vision,and many kinds of green plants appear in people's lives.Flowers are usually planted in the flower base or called a nursery base,these flower base usually in the form of flower greenhouses.The traditional planting methods entirely rely on manual management,the majority of flowers need farmers' all-time management,especially for some precious flowers,the works of farmer are huge time sinks.However,the awareness of many environmental factors is difficult to be judged accurately by human judgment.But for flowers,the small changes in environmental factors may have a great impact on their growth,such as excessive or insufficient soil moisture will cause adverse flower root growth.Therefore,the traditional flower shed management put forward higher requirements on farmers,and increased the difficulty of entering the ranks of planting flower growers at the same time.To a certain extent,it also affects the cost of flower planting and the price of flowers in the market.For that reason,this paper presents a new intelligent flower monitoring system based on ZigBee technology and optical fiber communication technology combined with intellectual agriculture.This system uses ZigBee wireless transmission technology to realize the function of intelligent monitoring and remote control of the greenhouse environment.The system consists of two parts:the upper computer and the lower computer.The role of the upper computer is to monitor and manage the node's environmental information,to display the warning information and providing user remote control functions.Lower machine contains two sets of ZigBee network,one set is used to collect and transmit environmental information such as temperature,humidity,light,etc.It also can be a manager to control the execution of user telecontrol commands.Another set of ZigBee is responsible for communication with the host computer,and the construction of the ZigBee network.At the same time,it is responsible for the summary of the data of the environmental monitoring nodes and the sending of control commands.The communication between the upper computer system and the lower computer system depends on the optical fiber communication,which realizes the long distance and reliable communication function.This paper also designs a set of video monitoring system based on optical fiber transmission,with the help of anti-jamming and low loss characteristics of optical fiber communication,it greatly improve the transmission distance of video monitoring,and improve the monitoring range of video surveillance,to solve the traditional network monitoring system for short distance transmission constraints,effectively improves the practicability of video surveillance in the system of intelligent greenhouse flowers.
