System Introduction: The remote monitoring system for agricultural greenhouse environment is composed of front-end components (temperature and humidity sensors, light sensors, CO2 concentration detectors, leaf surface humidity sensors, etc.) to monitor, summarize, convert, and transmit environmental parameters, including temperature, humidity, light, soil temperature, soil moisture, etc CO2 concentration, leaf surface humidity, and other environmental parameters are measured using different methods by data collection terminals to obtain highly accurate measurement data. The results are processed and converted through GPRS network to transmit data to an online monitoring data platform. The online monitoring data transmission platform is used to receive, filter, store, process, statistically analyze, and provide real-time data queries. When the temperature and humidity exceed the set threshold, the designated device is automatically turned on or off. The entire system can achieve: safe, reliable, accurate, real-time, comprehensive, fast, and efficient display of real greenhouse environment information in front of management personnel.
The remote monitoring system for agricultural greenhouse environment consists of three main parts: data center, greenhouse monitoring point, and user mobile phone.
1. Data Center: The data center is mainly composed of PCs and upper computers, which realize information management work such as data reception, storage, display, data request, curve display, report printing and output, as well as monitoring center warning for special situations, and conveniently access real-time and historical data through client software.
2. Greenhouse monitoring point: The greenhouse monitoring point collects real-time data on temperature, humidity, lighting, leaf surface humidity, soil temperature and humidity, soil pH value, etc. to the data collection terminal. Based on the real-time data, automatic alarms are triggered at the collection point to prevent accidents from occurring. (And reserve control interfaces for monitoring points)
3. User's mobile phone: Access the data center through the 3G smartphone app to collect real-time on-site data or edit text messages and send them to the data collection terminal to collect real-time on-site data. Main function: ◆ 24-hour collection
It can collect and record environmental parameters such as temperature, humidity, light, soil temperature, soil moisture, CO2 concentration, and leaf moisture in real-time for 24 hours online. The monitoring information can be displayed, recorded, and stored in various ways such as numbers, graphics, and images. There can be up to thousands of monitoring points.
◆ Powerful data processing and communication capabilities
By using computer network communication technology, any computer within the local area network can access the monitoring computer and view the temperature and humidity changes of the monitoring points online, achieving remote monitoring. The system can not only monitor in the duty room, but also be conveniently viewed and monitored by leaders in their own offices and smartphones.
◆ Chinese graphical interface
The data center software adopts a standard Windows 98/2000/XP fully Chinese graphical interface, which can display and record real-time temperature, humidity, light, soil temperature, soil moisture, CO2 concentration, leaf surface humidity and other curve changes of each monitoring point 24 hours a day. It can also collect historical data, values, small values and average values of environmental data such as temperature, humidity, light, soil temperature, soil moisture, CO2 concentration, leaf surface humidity, accumulate data, and alarm screens.
◆ Set alarm value
Alarm values for parameters such as humidity, temperature, light, soil temperature, soil moisture, CO2 concentration, and leaf moisture can be set for each monitoring point. When abnormal data occurs at the monitored point, an alarm signal can be automatically sent to the manager. The alarm methods include on-site media sound and light alarm, network client alarm, telephone voice alarm, mobile SMS alarm, etc. Upload the alarm information set by the user and perform local or remote monitoring. The system can notify the on duty personnel at different times.
◆ Data processing supports multiple formats
The system can be extended to various recording data analysis and processing software, which can be used to draw bar charts, pie charts, and perform curve fitting. It can output in TEXT format and also enter office software such as EXCEL spreadsheets for data processing.
◆ Printable data
The monitoring host can use monitoring software to print current environmental data and equipment operation reports such as temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, leaf surface humidity, etc. at any time.
◆ Hardware reduction software devices can be added at any time
When designing the system, there are reserved interfaces that can add or remove software and hardware devices at any time. The system only needs to make a small amount of changes and can complete other user requirements in a very short time. New content can be added or removed at any time according to changes in user policies. Main features: ◆ Easy to operate
The system software has complete functions, modular and graphical design, and the entire process is fully assisted in Chinese. The operation is simple and convenient.
◆ High cost-effectiveness
This system is tailor-made for remote environmental monitoring of greenhouses, fully considering the business needs of various links in agricultural greenhouse environments, and has a high cost-effectiveness.
◆ Simple equipment maintenance
The system can execute corresponding remote operation commands on the data collection terminal, including remote parameter setting, remote control, remote data copying, remote terminal reset, remote terminal software upgrade, etc.
The device runs smoothly
The agricultural greenhouse bases in our country are mainly located in remote suburban counties, so using a widely covered GPRS network with high signal is easy to capture. If necessary, high gain antennas can be used to ensure the normal operation of this equipment network.
◆ Data will never be lost
Integrated design, with a built-in large capacity storage chip in the terminal, ensures that data will not be lost even in the event of network failure.
◆ Support device addition and removal
Scalability, supporting smooth increase in the scale and quantity of main station devices, collection terminals, sensors, etc., without the need to modify application programs.
