Greenhouse environment cloud control system and control method thereof

Abstract

The invention relates to a greenhouse environment cloud control system and a control method thereof. According to the system, a cloud control end operates a control algorithm and stores data information; a controlled process end carries out remote communication with the cloud control end and performs data collection and control functions of the whole control system; a client monitoring end installs a mobile terminal with APP monitoring software and accesses a remote cloud control end through the mobile Internet; a management end accesses the remote cloud control end through the Internet and realizes cloud management of the whole system; and the control method is an interval control algorithm of a non-square control system. According to the system and the method, a control algorithm library and a database are arranged in remote cloud to form a cloud controller; rapid computing, non-disturbance rapid switching and the like of a complex control algorithm are finished through utilization of the strong computing capability of the cloud; large-scale data storage is realized; the controlled process end only needs to send filed collection data and receive a remote control signal through a high-speed remote communication channel; system costs of the system are clearly reduced; and the flexibility of the control system is improved.

Description

technical field [0001] The invention relates to an environment control technology in the agricultural field, in particular to a greenhouse environment cloud control system and a control method thereof. Background technique [0002] The control of the greenhouse environment is a part of smart agriculture, which plays an important role in meeting the needs of urban consumer groups, reducing planting risks, making full use of natural light sources, and promoting advanced agricultural technologies. As a controlled process, the greenhouse environment has two distinct characteristics in addition to the complex process multivariable, large lag, nonlinear, and strong coupling characteristics: one is the controlled variables (such as temperature, humidity, carbon dioxide, light, etc.) The number of variables is often more than the number of operating variables (sunroof opening, water spray volume, etc.), which belongs to a typical non-square control system (non-square thin system); t...
