Intelligent greenhouse management system based on Internet of Things

Abstract

The invention provides an intelligent greenhouse management system based on the Internet of Things. The intelligent greenhouse management system comprises a control terminal for displaying, transmitting and processing data, a coordinator for transmitting and receiving signals, a relay for controlling a feedback control circuit, a feedback control circuit controlled by the relay and used for starting and stopping corresponding facilities in a greenhouse, a monitoring network for collecting data in the greenhouse and a remote browser for the user access; and alarm upper and lower limits and an alarm stop value of the management system can be set by the user according to the actual conditions, and the performance is stable. Arbitrary placement of monitoring points is achieved, and the systemorganization is flexible; single-point or multi-point acquisition of multiple physical objects in the greenhouse environment is achieved; the number of monitoring objects and monitoring points in thenetwork can be increased or decreased according to the actual needs of the user, the monitoring data of different objects can also be calculated, processed and transmitted in the same network, and thesystem has good adaptability and compatibility; and the system has good working stability and measurement accuracy, a wide monitoring range, low energy consumption and a long running time.

Description

technical field [0001] The invention belongs to the technical field of agricultural greenhouses and relates to an intelligent greenhouse, in particular to an intelligent greenhouse management system based on the Internet of Things. Background technique [0002] The traditional agricultural structure model has great defects in terms of green environmental protection, energy conservation, high yield and high yield. Most of the commonly used farmland greenhouses do not have soil moisture monitoring methods, but use planting experience, visual inspection (observation) and other means to subjectively judge whether to irrigate, which not only wastes water resources, but also cannot make crops grow under suitable soil moisture; Eliminate the influence of ambient air temperature and humidity on crop growth. [0003] In recent years, IoT technology has been widely used in various aspects such as medical care, smart home, national defense, military, and intelligent transportation. A...
