Greenhouse intelligent control system based on Internet of Things technology

Abstract

The invention discloses a greenhouse intelligent control system based on Internet of Things technology. The intelligent control system is characterized in that the intelligent control system comprises an intelligent controller unit, a wireless sensor monitoring unit, a cell phone terminal containing control and monitoring app units, and a cloud end server end. The intelligent controller unit obtains environment data for storage and processing from the wireless sensor monitoring unit, and sends the environment data to the cloud end server and / or the cell phone terminal. The cloud end server receives the environment data sent by the intelligent controller in real time and is used for transmitting control command and request configuration command of the control and monitoring app units or / and the intelligent controller. The control and monitoring app units can search the environment data and control the intelligent controller unit, thereby controlling an external agricultural device connected to the intelligent controller unit. According to the invention, state multiple kinds of device control strategies like real-time monitoring, cloud end data storage, real-time searching of data flows by users, remote / local manual control, intelligent timed control and state coordinated control can be achieved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things and the field of automatic control, in particular to an intelligent control system for greenhouses based on the Internet of Things technology and a control method for the system, which are suitable for the cultivation and planting of greenhouse crops or flowers. Background technique [0002] As a traditional agricultural country, my country currently ranks first in the world in terms of greenhouse area. However, in terms of planting methods, most greenhouses in my country still adopt a purely manual extensive management method, which not only wastes manpower and material resources, but also has low yield and poor quality of crops. Therefore, it is urgent to change the low-efficiency management and operation status of greenhouses, develop new technologies for greenhouse management, and realize large-scale, intensive, intelligent, industrialized, and networked management of greenhouse...

AI Technical Summary

Problems solved by technology

[0005] However, the intelligent greenhouse monitoring system at this stage has the following deficiencies: first, the wired communication environment is humid and high temperature, and the soil and air have strong acidity and alkalinity, and the communication cable is prone to failure, which reduces the reliability of the system; The area is large, and more sensor nodes need to be arranged to collect information, and crisscross lines need to be laid, which is difficult to maintain, and at the same time, the flexibility is poor, and the function expansion is also limited. The third is that the detection system has many applications and lacks intelligence. Control section

Fourth, there are many shortcomings in the existing automatic configuration methods, such as wired network configuration methods, USB or serial port configuration methods, the hardware cost is relatively large

The disadvantage of the Bluetooth configuration method is that it is slow and the configuration process is complicated.

The WPS configuration method needs to provide a router that supports WPS, and this configuration method is greatly disturbed by the environment

Fifth, the processing of multi-sensor data by the existing intelligent control system is not accurate enough, resulting in large data errors
