China is a major agricultural country, but agricultural production has long faced the dilemma of "difficulty in determining soil moisture and relying on experience for irrigation". Especially in the context of climate change, frequent disasters such as droughts and floods have further exacerbated the difficulty of soil moisture management.
Traditional soil moisture judgment relies on farmers´ empirical method of "pinching hands and treading feet", or the detection method of manual soil sampling and weighing, which has obvious limitations: empirical judgment is subjective, and different farmers have a large difference in cognition of "dry and wet", which easily leads to deviation in irrigation timing and water volume; manual soil sampling detection is time-consuming and laborious, and can only reflect the single point and instantaneous soil moisture, which can not achieve regional and dynamic monitoring. The blind area of soil moisture in mountainous areas, fields and other large planting areas is particularly prominent. When encountering sudden drought or short-term rainstorm, it is difficult for farmers to quickly grasp the change of soil moisture throughout the region, often missing the best opportunity for irrigation or waterlogging drainage, resulting in irreparable losses. In this context, it can be real-time and accurate capture The professional monitoring station of soil moisture has become the key to solving the problem of "eating by moisture".
The soil automatic monitoring station can achieve 24/7 uninterrupted monitoring. The system can comprehensively, scientifically, and truthfully reflect the changes in soil moisture in the monitored area. The on-site remote monitoring equipment automatically collects real-time soil moisture data and uses GPRS wireless network to achieve remote data transmission; The monitoring center automatically receives and stores monitoring data from each monitoring point into the database. It can provide timely and accurate soil moisture conditions at various monitoring points, providing important basic information for disaster reduction, drought resistance, fertilization, and irrigation.
Product features
1. Real time monitoring of soil temperature and humidity, with flexible single channel measurement or multi-channel profile measurement at each monitoring point. Provide important basic information for fertilization and irrigation.
When the soil moisture exceeds the pre-set limit, an alarm message can be reported to the user through GPRS to provide farmland environmental information for remote fertilization control.
3. Expand monitoring functions for soil salinity, nitrogen, phosphorus, potassium, pH value, negative oxygen ion concentration, particulate matter, weather temperature and humidity, CO2 concentration, etc.
4. The frequency of data collection and storage can be flexibly adjusted, and the working parameters of monitoring equipment can be remotely set.
5. Remote monitoring equipment only supplies power to sensors when collecting data, which saves energy and avoids measurement errors caused by changes in soil physical properties due to long-term power supply.
6. Supports multiple communication methods such as GPRS, short message, local area network, etc. It is recommended to use GPRS wireless communication.
7. Monitoring data can be reported to multiple centers simultaneously.
8. It has statistical and analytical functions for monitoring data and alarm data, and data reports can be exported and printed out.
9. The monitoring system software has GIS function and can display the detailed distribution location of each monitoring point on the map.
10. Used for all-weather on-site monitoring of soil temperature, soil moisture, soil pH and other factors. It can be connected to a computer through a professional data collection communication cable, and the data can be transmitted to the soil computer soil database for statistical analysis and processing.
11. The soil moisture data recorder has functions such as soil moisture data collection, timed storage of soil moisture data, parameter setting, user-friendly software human-machine interface, and standard communication. It can display graphical data and has wired communication. It can run in Windows 2000 or above system environment and store data in EXCEL standard format. It can generate meteorological data charts for other software to call.
12. LED wireless information publishing platform: professional and simple operation, convenient management, stable transmission, high reliability; It can transmit program information such as text without distance limitations and has a wide range of applications; After the terminal goes offline and goes online, it can be resumed to save data
13. Wired transmission method: Connect to the monitoring center PC via a standard USB/RS485 communication interface and transmit collected data in real-time.
14. Wireless transmission method: As long as there is internet access, data can be viewed and analyzed through GPRS wireless transmission for web browsing.
