Description

Intelligent monitoring system for greenhouse based on internet of things

Technical field

The invention relates to the field of intelligent monitoring technology, and in particular to a greenhouse intelligent monitoring system based on the Internet of Things.

Background technique

In recent years, China's facility horticulture has developed rapidly. As of 2012, the cultivated area has reached 3.62 million hm2, accounting for 89.3% of the world; the glass greenhouse area representing the modernization level of facility horticulture is close to 9000hm2, accounting for 22.5% of the world's glass greenhouse area. Greenhouse environmental monitoring system is a key technology to increase greenhouse crop yield and reduce labor costs, and represents the core competitiveness of greenhouse production.

With the rapid development of sensor technology, computer control, network communication, and the Internet of Things, intelligent monitoring systems incorporating the above-mentioned high-tech technologies are gradually being applied to the field of greenhouse monitoring. However, the above-mentioned system mainly focuses on the acquisition of environmental information and simple control of equipment in a single greenhouse. Its intelligence is not high, its versatility is not strong, and it is difficult to expand and apply to the environmental regulation of large multi-span greenhouses. However, the construction of domestic greenhouses is mainly based on greenhouse groups composed of multiple greenhouses. Under this new situation, it is required that the current intelligent greenhouse monitoring system should be based on a unified agricultural IoT technology framework in terms of software and hardware design, and ensure equipment. Under the premise of controlling security, environmental intelligent control algorithms are applied to the actual production management of the greenhouse, and a highly scalable and versatile greenhouse environment intelligent monitoring system is constructed.

Summary of the Invention

Purpose of the invention: The purpose of the present invention is to provide an intelligent monitoring system for a greenhouse based on the Internet of Things, which can realize automatic collection, real-time display, and visual data query and analysis of greenhouse environmental parameters. In particular, it can monitor the working status of field equipment and realize intelligence. Control and combine the working characteristics of greenhouse equipment.

The technical solution adopted by the present invention is a greenhouse intelligent monitoring system based on the Internet of Things, which includes a remote monitoring system, a database, and a field monitoring system. The remote monitoring system includes a Web server, an administrator terminal, and a user terminal. The field monitoring system is placed in the greenhouse. It includes a monitoring computer, a real-time data acquisition module, a data storage management module, a device control module, and a video monitoring module. The real-time data acquisition module, data storage management module, device control module, and video monitoring module communicate with the monitoring computer, and then communicate with the monitoring computer. The database performs data transmission and communicates with the Web server, uploading on-site monitoring data to the server and sending it to administrators and user terminals.

The real-time data acquisition module, the data storage management module, the device control module, and the screen monitoring module communicate with the monitoring computer through a CAN bus.

Beneficial effect: An intelligent monitoring system for a greenhouse based on the Internet of Things according to the present invention realizes automatic collection, real-time display, and visual data query and analysis of greenhouse environmental parameters, and in particular, it can monitor the working status of field equipment and implement intelligent control. Combined with the working characteristics of greenhouse equipment.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a frame diagram of the present invention.

detailed description

The specific embodiment is further described below with reference to the accompanying drawings:

As shown in Figure 1, an intelligent monitoring system for a greenhouse based on the Internet of Things includes a remote monitoring system, a database, and an on-site monitoring system. The remote monitoring system includes a Web server, an administrator terminal, and a user terminal. The on-site monitoring system is placed in the greenhouse. Including monitoring computer, real-time data acquisition module, data storage management module, equipment control module and video monitoring module, said real-time data acquisition module, data storage management module, device control module and video monitoring module communicate with the monitoring computer, and then communicate with the database Perform data transmission, and communicate with the web server, upload the on-site monitoring data to the server and send to the administrator and user terminal.

The on-site monitoring subsystem is a C / S architecture. The monitoring software running on the on-site monitoring computer communicates with the greenhouse data acquisition and control system based on the distributed CAN bus through the CANOpen protocol to achieve the collection of the main environmental factors of the greenhouse and the control of the equipment. The input module receives the greenhouse microclimate environmental factors (air temperature, humidity, solar radiation, etc.) and outdoor weather information (air temperature, humidity, wind speed, wind direction, light intensity, etc.) collected by the sensor, sends them to the CAN bus, and monitors the computer on site These data are received through the CAN communication card and displayed in real time, and stored in the database at the same time. The output module receives control signals from the field monitoring software through the CAN bus to control the actions of the relays. The corresponding actions of the relays control the start and stop of the greenhouse environmental control equipment (fans, skylights, wet curtains, shade nets, etc.).

The database is between the remote monitoring subsystem and the on-site monitoring subsystem, which is the bridge between them. The on-site monitoring subsystem stores the processed real-time environmental data, equipment status information, and equipment control logs into a database for users to conduct historical query and analysis. The remote monitoring subsystem displays information stored in the database to remote users on the one hand, and writes control commands of remote users into the control decisions of the database on the other hand. The on-site monitoring subsystem polls the control decision table in real time to control the greenhouse equipment. .

The technical content and technical features of the present invention have been disclosed as above. However, those skilled in the art may still make various substitutions and modifications without departing from the spirit of the present invention based on the disclosure of the present invention. Therefore, the protection scope of the present invention should not be limited to the embodiments. The disclosed content should include various substitutions and modifications that do not depart from the present invention and are covered by the claims of this patent application.
