Agricultural Internet of Things Application-Smart Greenhouse System, Facility Agriculture Management Assistant

The application of the Internet of Things system has been applied in many fields and industries, such as the Internet of Vehicles, the Agricultural Internet of Things, etc. There are also many specific single application projects in the Agricultural Internet of Things, including soil moisture monitoring, intelligent irrigation, intelligent water supply, etc. Among them, the smart greenhouse system has a number of applications, which fully reflects the advantages of the Internet of Things in agricultural applications.

The application of the Internet of Things system generally includes data acquisition, intelligent control, data transmission and so on. Through the sensor node installed in each production area, the sensor collects data according to the set timing length. Now the collection frequency of the sensor is generally once a minute. Through a low-power wireless communication technology of self-organizing network, data transmission is realized, and all data are collected to the central node, thus establishing the connection between the wireless gateway and the Internet, and using mobile phones or computers to grasp the environmental status information of the production area in real time, diagnosing the growth of crops, poultry or aquatic products based on environmental parameters is the principle of agricultural IoT applications.

The intelligent greenhouse system embodies the application of the agricultural Internet of things system in detail. The sensor nodes such as soil temperature and humidity, illuminance, carbon dioxide, etc. form a monitoring network to collect the temperature, humidity, light, carbon dioxide and other production in the greenhouse, 24-hour online monitoring, data transmission wireless transmission data upload cloud platform, to realize real-time monitoring, thus linkage control of water and fertilizer integrated machine, rolling machine and other equipment, real-time control. Find the problem in time and quickly determine the cause of the problem.

The greenhouse was originally designed to change the climate and seasonal restrictions on crop growth, and was roughly adjusted according to past planting experience. With the help of Internet of things sensing technology and equipment, the intelligent greenhouse system accurately collects various environmental parameters of the greenhouse, takes different measures to regulate the indoor temperature and humidity according to different situations, and pertinently regulates ventilation, irrigation, fertilization and medicine application, further refines the extensive management of the original greenhouse, changes the growth environment inside the greenhouse, and provides a suitable growth environment for crops.

The intelligent greenhouse system can timely and accurately grasp the time of crop medication and fertilizer use in facility gardening, effectively reduce the use of pesticides and chemical fertilizers, greatly improve the utilization rate of pesticides and chemical fertilizers, reduce the carrying pressure of the environment, and at the same time reduce labor and save production costs. According to estimates, the general yield can be increased by 10%, and the income per mu of greenhouse can be increased by more than 1500 yuan.

If the environmental data detected by the sensor exceeds or falls below the value set by the manager on the cloud platform, the system will automatically trigger the alarm mechanism, which can quickly find the failure point of the greenhouse and respond positively.

With the continuous application of the agricultural Internet of Things system, the functions of the smart greenhouse system are also being continuously improved. Recently, the team of Professor Xu Lihong of Tongji University, with the help of the smart greenhouse, explored the multi-factor coordinated control technology of blueberries, which successfully made blueberries go on sale one month earlier, and the quality has also been greatly improved, resulting in good economic benefits. I believe that in the future, more high-quality fruits and vegetables will be grown through the smart greenhouse system, which will truly bring real benefits to farmers.
