Research On Plant Illumination System Based On Wireless Network Communication Technology

At present,the agricultural production in most areas of China is still dominated by traditional agricultural production methods,which not only causes a lot of waste of human and material resources,but also has problems of high investment and low returns.At the same time,with the acceleration of the urban-rural integration process in our country,the rural population has been continuously lost,and the area of arable land has been continuously reduced.With the development of modern information technologies such as the Internet of Things technology,smart agriculture has become the trend of future agricultural development.By applying modern information technology such as Internet of Things technology to agricultural production,it can effectively reduce the use of human and material resources,improve agricultural production efficiency,and is the best choice to solve the current agricultural problems in China.Bluetooth mesh technology,as an emerging wireless network technology,has the characteristics of low power consumption,ad hoc network,long communication distance,simple operation,and high transmission rate.It can quickly and effectively provide users with data transmission functions,so it is applicable to many fields of the Internet of Things.This thesis discusses domestic and foreign achievements in agricultural informatization construction and the latest research progress.Based on the current research hot spots in society,the design scheme of smart agricultural plant lighting system based on Bluetooth mesh technology is given.Firstly,this article introduces the Bluetooth mesh technology in detail,and gives the overall design framework of the system according to the application requirements of the greenhouse.At the same time,according to the system framework,the functional modules that need to be designed,including the main control module and the power module,Lighting module,pwm dimming module,sensor module.The Bluetooth mesh network node is composed of a main control module and a function module.The main control module and the lighting module form a Bluetooth mesh lighting node,and the sensor module forms a Bluetooth mesh sensor node.The main control module is mainly used for data transmission and processing.The system collects required data through the sensor module and transmits it to the main control module.The main control module can also control the light intensity and spectral value through the pwm dimming module and lighting module.It can realize the control and management of Bluetooth mesh network nodes,and achieve the purpose of monitoring and adjusting the agricultural greenhouse greenhouse planting environment near and remotely.Finally,this article summarizes all the completed work,and gives further work prospects in light of the current domestic agricultural development status and technological research progress.
