Agricultural greenhouse intelligent control device based on Internet of Things

Abstract

The invention discloses an agricultural greenhouse intelligent control device based on the Internet of Things. The agricultural greenhouse intelligent control device comprises a control center, a communication module, a data acquisition module, an environment regulation and control module and a video monitoring module. The control center is composed of a processor, a data analysis system, a database system, a fault diagnosis system and an early warning system. The communication module adopts a wireless network for data transmission, and the wireless communication module is responsible for reporting monitoring data among greenhouses and issuing a central station control command; the data acquisition module comprises a soil temperature and humidity detection unit, an illumination intensity detection unit, an air temperature and humidity detection unit and a CO2 concentration detection unit; the environment regulation and control module comprises a rainwater collection unit, an irrigationunit, a ventilation unit, a temperature and humidity regulation and control unit and an illumination regulation and control unit. According to the agricultural greenhouse intelligent control device,all the modules cooperate with one another, intelligent control over the greenhouse is achieved, and the agricultural greenhouse intelligent control device has the advantages of being accurate, stable, maintainable, upgradable, extensible, economical, applicable and the like.

Description

technical field [0001] The invention relates to the field of intelligent control of greenhouses, in particular to an intelligent control device for agricultural greenhouses based on the Internet of Things. Background technique [0002] At present, most agricultural greenhouses are still managed by traditional manual methods. If you want to obtain the crop parameters, soil and environmental parameters and the status of control equipment in the greenhouse, you must go to the greenhouse to collect them. This makes the management of the greenhouse both time-consuming and laborious and inefficient. At the same time, the traditional greenhouse irrigation method still uses flood irrigation, which causes a lot of waste of water resources. Agricultural intelligent greenhouse is the main development direction of modern agriculture. It is a general term for agricultural production activities integrating environment, biology, information science and other technologies; it is a modern i...

Problems solved by technology

[0003] The existing smart greenhouse control technology has the following problems: (1) The environmental control standard of smart greenhouses is not high: the existing smart greenhouses are mostly solar greenhouses and plastic greenhouses, with simple structures and poor weather resistance, and manual control methods are mostly used. Control, the ability to regulate environmental factors such as temperature, humidity, and light intensity in the greenhouse is weak; (2) Smart greenhouses are not highly intelligent: At present, most smart greenhouses in my country use wireless networks to collect environmental factors in the greenhouse through MCU microcontrollers. And upload the data to the server through the wireless network, and then issue control commands to adjust the environment in the greenhouse. Although this control method can control the environment in the greenhouse wirelessly and remotely, it does not add a control algorithm, which makes the degree of intelligence not high; (3 ) is not highly networked

The wireless network of the intelligent greenhouse control system mostly uses ZigBee networking or 433MHz frequency wireless module networking to realize wireless transmission of data inside the greenhouse. The transmission distance of this wireless network is about 70m, and the network stability is not strong
