Designing smart greenhouses, satisfactory price-quality
Abstract
Smart greenhouse is a revolution in agriculture, which creates a self-regulating microclimate suit-able for plant growth through the use of sensors, actuators and control and management systemsthat optimize growth conditions and automate the growing process. The global smart greenhousemarket was valued at approximately 680.3 million in 2016 and is expected to reach approximately1.31 billion by 2022, an increase of 14.12% on average between 2017 and 2022.However, high installation prices and high upfront investment costs can constrain greenhouseadoption in many underdeveloped and developing countries. Therefore, the urgent task is the de-velopment and implementation of smart greenhouses that are suitable for the wider population,which provide the population with vegetables and fruits seasonally or year-round. Improving thequality of service of greenhouses, controlling and monitoring microclimate processes is possiblethrough the use of programmable logic controllers, modern smart, wireless and web technologiesWSN and IoT.The article is devoted to the design of the Home Smart Greenhouse system, the control device ofwhich is implemented on the basis of NLC. The system allows you to perform a) control (monitor-ing) of microclimate processes in Online mode; b) fuzzy control in manual and automatic mode;c) adjust the parameters of the three microclimate processes: cooling, watering and lighting.The described NLC model adequately reflects the microclimate control process in the greenhouse. As a result of using the system, the productivity of the farmer user is increased, thereby helpingthe farmer user control the plant growth process and take the necessary measures to care for them.The developed system meets the criterion of price-quality, that is, it is simultaneously accessible tothe population, and at the same time has an acceptable quality of service, using wireless networkand web technologies (WSN, IoT) and fuzzy control. The cost of the system is 86.75 (the price isnot higher than the minimum wage of Kazakhstan), the economic effect of using the system is 25,the payback period of the greenhouse is 4 seasons.
