Design of intelligent greenhouse monitoring system

Design of intelligent greenhouse monitoring system

(1) Intelligent greenhouse monitoring system design requirements

1. The intelligent control system of heliostat is a complex system involving various factors such as temperature, humidity, carbon dioxide concentration, light intensity and vegetable varieties. Therefore, the design of the system should have the following functions.

1、Wider working voltage range: 160V one by one 260V Ac.

2、Ability to work continuously, stably and reliably for a long time.

3、Can make accurate measurement of temperature, humidity, carbon dioxide concentration, light intensity and other parameters in the greenhouse.

4、It can set the alarm range of temperature, humidity, carbon dioxide concentration, light intensity and other parameters manually/automatically according to the different vegetable varieties.

5、The control status of the system can be set: manual control status and automatic control status. In the manual control state. The system only has the function of parameter detection and warning, and does not control the motor, pump and other control equipment. In the automatic control state, the system has both parameter detection and warning function, and can automatically regulate the motor, pump and other control equipment.

6、The front-end equipment inside the greenhouse can work individually, but also has data remote transmission and networking functions.

7、The computer in the testing center can be connected to multiple front-end devices through 4G network or Zigbbe network, and can detect and control the controlled objects of these devices.

(2) Intelligent greenhouse monitoring system design principles

1、Stable performance and reliable operation of the system.

2、Simple operation and easy maintenance.

3, the whole system is easy to expand.

4, economic operation and energy saving, low maintenance costs.

5、High performance to price ratio.

(3) The overall architecture of intelligent greenhouse monitoring system

The system adopts the upper and lower computer control scheme. The lower computer is the front-end controller of the system, which implements the detection of environmental parameters of greenhouse and the control of environmental adjustment mechanism; the upper computer is the remote monitoring computer of the system, which adopts the visual programming language to design the environment monitoring and management system with friendly interface to realize the remote monitoring and management operation of greenhouse.
