Greenhouse planting is a commonly used planting technique in modern agriculture. It plays an outstanding role in preventing plants from cold, preventing winter or promoting growth and early flowering and fruiting. The environmental conditions such as temperature, humidity, light, and carbon dioxide concentration in the greenhouse affect the growth of crops. The key factor. Therefore, timely monitoring of indicators such as temperature, humidity, and illuminance in the greenhouse to ensure good "microclimate" conditions is an issue that every greenhouse manager must consider.
The environmental monitoring and control system in the greenhouse constitutes the perception layer:
Perception layer: The system perception layer is composed of various IoT devices. In the greenhouse environment monitoring system, it consists of sensors such as temperature, humidity, light, CO2 sensors, and IoT control terminal cabinets, which are used to detect environmental data and fans in the greenhouse. , Spray, wet curtains and other equipment, shading roller blinds and other equipment operating information, and realize the on-off and status control of related equipment.
Transmission layer: Through various communication protocols, the system transmission layer transmits environmental information such as temperature, humidity, illuminance, and spray and fan device status information detected by sensors and IoT controllers to the server and sends it to the user's computer or mobile phone; The control commands for the fan and spray equipment are also sent to the IoT controller through the transmission layer, so as to realize the control of the equipment and change the environmental conditions such as temperature and humidity.
Application layer: The platform layer in the temperature and humidity monitoring system refers to the comprehensive management and control cloud platform of the Internet of Things. The platform integrates many functions such as data monitoring, equipment control, abnormal alarms, data reports, etc., which can not only help users detect and control the temperature in the greenhouse in real time. Humidity environment can also improve the level of security and optimize management strategies.
The data monitoring function of this system can display the temperature and humidity, CO2 concentration, equipment operation information and other data of each monitoring point in the computer or mobile phone interface. The user can grasp the temperature and humidity, light intensity information and fan, The operation information of supplementary lights, insecticidal lights, sprinklers and other equipment; click on the relevant data card, you can also display the changes in the target data within a certain period of time.
Shengqi system supports the equipment control function. Users only need to click the corresponding equipment card on the control interface to call out the equipment control window, and click the corresponding button to control the air conditioning and spray equipment in the greenhouse. Through custom logic settings, users can also set the automatic start-stop control of air conditioners and other equipment according to the temperature and humidity changes in the greenhouse.
The system has an abnormal alarm function. Whether the detected temperature, CO2 concentration and other data exceed the normal limit, or the communication is abnormal or the device is offline due to network fluctuations, power outages, etc., the system will alarm the user according to the settings. The alarm method supports APP, SMS, phone, WeChat, email, etc., to ensure that the alarm information is delivered to the user in time to avoid losses.
The system supports video surveillance function and can be connected to a variety of video equipment. As long as it is connected to the Internet, you can view the video status in the greenhouse anytime, anywhere through your mobile phone or computer. It provides users with more convenience in observing the growth status of crops, preventing theft, and tracing history.
The system has a configuration screen function, which can display environmental data information such as temperature, humidity, light, and equipment status on the plan. The user can easily judge the environmental information such as temperature, humidity, light, and specific equipment in the schematic diagram. According to the current state of the device, the device can be directly controlled on this interface.
The system is equipped with big data analysis and processing functions, which can comprehensively process the collected environmental information and equipment status information, and can also display data analysis results through bar graphs and pie charts. Users can rely on the results of data analysis to dynamically adjust management strategies such as temperature, room temperature, humidity, and light, to ensure the most suitable growth environment for crops, and ultimately achieve the goal of increasing production and income.
