ABSTRACT

Fast increase of Earth population during the last decades raised a serious problem when it came to providing fresh and good quality food (mainly vegetables) in big quantity over a short period of time. Due to relatively long lifecycles of plants when growing in gardens or fields, the best solution consisted in using greenhouses. Greenhouses proved to be a very important solution since they are capable of operating regardless of local environments if minimum requirements (heating and water) are provided. By offering optimum growing conditions for the plants, the greenhouse environments not only stimulate a shorter lifecycle but also offer almost perfect protection against pests or plants diseases. An even better solution is represented by hydroponic greenhouses which exhibit several advantages over traditional greenhouses: they do not need earth for growing plants, the size and location are less restrictive, the plant cultures can be overlapped and the nutrients and other parameters can be controlled and personalized more efficiently. However, this comes with a higher cost for implementing and using automatic control architecture. In addition to specialized sensors, efficient solutions for data transmission, control and command must be used. In this paper a hydroponic system is presented. It aims to control not only a greenhouse but a set of greenhouses by aggregating them into a complex grid alike mechanism of monitoring and control. Intermediate results prove the solution is functional but the final architecture is not yet finalized.
