Wireless Monitoring and Control Solution for Greenhouse

1. Background

With the development of science and technology and the improvement of people's living standards, the demand for greenhouse planting is becoming more and more important.

The traditional greenhouse is usually just a big shed, lack of systematic monitoring facilities and automation control facilities. Users can not grasp soil information and climate information in time, which leads to failure to take corresponding adjustment measures in time to ensure the healthy growth of crops, and it is easy to cause losses to farmers.

The modern greenhouse wireless monitoring and control solution adopts wireless data transmission terminal, connects various functional sensors and controllers, and builds a perfect and highly automated wireless measurement and control system with strong monitoring center.

2. Solution

The greenhouse environment measurement and control system is mainly composed of sensor equipment, data transmission equipment and monitoring center system.

Monitoring center: mainly responsible for data collection, reception, analysis, processing, and data push and so on. It is mainly composed of server, communication software, management platform, database and so on.

Data transmission terminal: each greenhouse has aBaimaBMD200 data terminal unit, which adopts module integrated design. According to industrial standard and the needs of industrial users, it has the advantages of fast and flexible networking, short construction cycle and low cost. BMD200 dial-up Internet through 2G/3G/4G network, and take the initiative to establish a connection with the server, automatic construction of data channels, while BMD200 can easily meet industry protocol customization, various sensors docking, on-site real-time monitoring management platform can make all kinds of information, and promptly issued a variety of control

Sensor equipment: mainly air temperature and humidity sensor, soil moisture sensor, electromagnetic valve, relay, fan, light sensor and so on. It is mainly used for real-time monitoring of various environmental information.

To establish a communication link between the platform and sensor equipment via data terminal unit, various front-end sensor devices for induction of air and soil information, and real-time data reported to the platform, the platform is responsible for sending control commands, or sending the measurement command.

3. The advantages
