In recent years, the emergence of agricultural greenhouses has brought great convenience to improve people's living standards. Therefore, agricultural greenhouses have been rapidly promoted and applied. During the growth of crops, environmental factors such as temperature, humidity, light intensity, and CO2 concentration in the environment have a great impact on crop growth and yield. Traditional manual monitoring methods are difficult to meet the requirements of scientific planting. At present, China's technology to achieve automatic monitoring of the above environmental factors is still immature. If we introduce foreign multi-functional large-scale greenhouse control systems, the price is expensive, which is not conducive to the long-term stability and rapidity of China's agriculture. Development of national conditions.
。 In view of the current development trend of agricultural greenhouses in China, we have proposed a design scheme of a greenhouse greenhouse remote monitoring system . According to the particularity of greenhouse monitoring--the real-time parameters of greenhouse greenhouses need to be transmitted to the managers in real time, and the manager's orders are sent to the on-site execution equipment, and at the same time, the superior department can understand the area of the greenhouse through the Internet or mobile phone information at any time. Real-time status of the crop. The remote monitoring system for agricultural greenhouse environment based on GPRS , which was developed and designed by Chengdu Xinxin Electronic Technology Co., Ltd. , makes these possible.
The remote monitoring system for the greenhouse environment of agricultural greenhouses consists of front-end parts ( temperature and humidity sensors , light sensors , C02 concentration detectors, foliar humidity sensors, etc.) to complete the monitoring, aggregation, conversion and transmission of environmental parameters. Environmental parameters include temperature, Humidity, light, soil temperature, soil humidity, CO2 concentration, leaf surface humidity, etc. These environmental parameters are measured by the data acquisition terminal using different methods to obtain a very accurate measurement data. This result is converted through data processing to the GPRS network. The online monitoring data platform transmits data. The online monitoring data transmission platform implements data reception, filtering, storage, processing, statistical analysis, and provides real-time data query tasks. When the temperature and humidity exceed the set threshold, the designated data is automatically turned on or off. device. The entire system can achieve: safe, reliable, accurate, real-time, comprehensive, fast, and efficient display of real greenhouse environmental information in front of managers.
The agricultural greenhouse greenhouse environment remote monitoring system consists of three parts: data center, greenhouse monitoring point, and user's mobile phone.
1. Data center: The data center is mainly composed of a PC and a host computer. It implements data management, such as data reception, storage, display, data request, curve display, report printout, etc., and special center monitoring and early warning. Client software provides easy access to real-time and historical data.
2. Shed monitoring point: Shed monitoring point will collect the temperature, humidity, light, leaf humidity, soil temperature and humidity, soil ph value and other data into the data collection terminal in real time. Prevent accidents. (And reserve the control interface of the monitoring point)
3. User mobile phone: Access the data center to collect live real-time data through the 3G smartphone App or edit the short message to send to the data collection terminal to collect live real-time data.
【The main function】
◆ 24 hours collection
It can collect and record the temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, leaf humidity and other environmental parameters of the monitoring point continuously for 24 hours in real time online, using digital, graphics and images, etc. Real-time display and record storage monitoring information, monitoring points can be up to thousands of points.
◆ Powerful data processing and communication capabilities
Using computer network communication technology, any computer in the local area network can access the monitoring computer, check the temperature and humidity changes at the monitoring point online, and realize remote monitoring. The system is not only able to monitor in the duty room, the leaders can easily watch and monitor in their own offices and smart phones.
◆ Chinese graphic interface
The data center software uses a standard Windows 7/8/10 full Chinese graphic interface, which can display and record the temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, leaf humidity and other curve changes at various monitoring points in real time for 24 hours. Environmental data such as temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, leaf surface humidity, historical data, value, small value and average value, cumulative data, alarm screen.
◆ Set alarm value
It can set the alarm value of humidity, temperature, light, soil temperature, soil humidity, CO2 concentration, leaf humidity and other parameters at each monitoring point. When the data of the monitored point is abnormal, it can automatically send an alarm signal to the manager. Alarm methods include: on-site media sound and light alarm, network client alarm, telephone voice alarm, mobile phone short message alarm, etc. Upload the alarm information set by the user and perform local or remote monitoring. The system can notify the staff on duty at different times.
◆ Data processing supports multiple formats
The system can be extended with a variety of recorded data analysis and processing software, which can process histograms, pie charts, and curve fitting. It can be output in TEXT format, and can also enter office software such as Excel spreadsheets for data processing.
◆ Printable data
The monitoring host can use the monitoring software to print the current environmental data and equipment operation reports such as temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, leaf humidity, etc. at any time.
◆ Hardware and software equipment can be added at any time
The system has a reserved interface when designing. It can add and subtract software and hardware equipment at any time. The system only needs to make a small number of changes, which can complete other user requirements in a short time. New content can be added or removed at any time according to changes in user policies.
◆ Simple operation
The system software has perfect functions, modularization and graphic design, full Chinese help throughout the process, and simple and convenient operation.
◆ High cost performance
This system is tailor-made for the remote environment monitoring of the greenhouse, which fully considers the business needs of all aspects of the agricultural greenhouse environment, and has a high cost performance.
◆ Easy equipment maintenance
The system can execute corresponding remote operation commands to the data collection terminal, including remote parameter setting, remote control, remote data copying, remote terminal reset, remote terminal software upgrade, etc.
◆ The equipment runs smoothly
China's agricultural greenhouse bases are basically located in remote suburban areas. Therefore, the high-signal coverage of the GPRS network with wide coverage is easy to capture. If necessary, high-gain antennas can be used to ensure the normal operation of this equipment network.
◆ Data is never lost
Integrated design, the terminal has a built-in large-capacity storage chip, which guarantees that data will not be lost even if the network fails.
◆ Support equipment increase or decrease
Scalability, supporting the smooth increase in the number of scales, such as master station equipment, acquisition terminals, sensors, etc.
