Modern agriculture needs to be able to remotely obtain the air temperature and humidity, soil moisture temperature, carbon dioxide concentration, light intensity and video images inside the greenhouse in real time for the needs of industrialization and production. Through model analysis, remote or automatic control of wet curtain fans and sprayers is required. Equipment such as drip irrigation, internal and external shading, roof windows and side windows, and heating and supplementary lighting ensure that the environment in the greenhouse is the most suitable for crop growth and create conditions for high yield, high quality and safety of crops. Since the agricultural greenhouse base is basically located in remote areas, it adopts a wide-covered GPRS network for high-signal capture and high-gain antennas to ensure the normal operation of the network.
The agricultural wireless monitoring system developed by Zhongwei Intelligent Technology uses the Internet of Things technology to continuously collect and record the temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, leaf surface humidity, and dew point temperature of the monitoring point 24 hours online and in real time. The monitoring information can be displayed, recorded and stored in real-time in a variety of ways such as digital, graphic and image. The temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, leaf surface humidity, dew point temperature and other alarm limits of each monitoring point can be set, and an alarm signal can be automatically sent out when the monitored point data is abnormal. The monitoring host can use the monitoring software to print environmental data and operating reports such as temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, leaf humidity, and dew point temperature at any time at any time. The interface is reserved during system design, and hardware and software equipment can be added or reduced at any time. The system only needs to make a few changes, which can be completed in a short time. New content can be added at any time according to changes in policies and regulations. It has the function of alarming at all times of intrusion. This system is an integrated design, easy to install and maintain. With scalability, it supports the smooth increase of the number of main station equipment, acquisition terminals, sensors, etc., without modifying the application program.
