Soil moisture monitor is an important technical means to achieve disaster prevention, drought resistance and water-saving irrigation in modern agriculture. It builds a monitoring network through professional equipment and network technology to provide data support for agricultural production management.
The system consists of three parts: management cloud platform, communication network and monitoring equipment, which can conduct long-term continuous monitoring of soil conditions. Farmers can flexibly arrange equipment according to their needs to fully reflect the soil changes in the monitoring area, timely provide the moisture status of each monitoring point, and lay a foundation for disaster reduction and drought resistance.
Each component of the system has clear functions:
Monitoring center: The hardware includes servers, computers, etc., and the software includes operating systems, databases and management cloud platforms. Farmers do not need to prepare their own servers. They can check the real-time moisture situation and receive alarm messages by installing the cloud platform APP or logging in to the web page on Android / IOS mobile phones, computers, tablets and other devices.
Communication network: Wireless networks such as GPRS can be selected according to the network conditions of the actual environment.
Monitoring equipment: Considering the scattered distribution of soil moisture monitoring points and the characteristics of wiring, common equipment includes soil temperature and humidity sensors, PH value sensors, conductivity sensors, rain and snow sensors, illumination sensors, etc. These can obtain data such as soil water content, pH value, EC value, etc. The monitoring frequency can be set to once every 1 minute, realizing 24-hour uninterrupted monitoring.
The system has expansion capability. Corresponding sensors can be added to monitor soil temperature, conductivity, PH value, groundwater level / water quality, as well as air temperature and humidity, light intensity, wind speed and direction, rainfall and other information, so as to meet the needs of function upgrading.
The working process is as follows: The on-site remote monitoring equipment automatically collects real-time moisture data, which is remotely transmitted through GPRS wireless network. The management cloud platform automatically receives and stores the data in the database to realize all-weather monitoring.
By monitoring soil temperature, moisture and water level, rational irrigation can be realized, avoiding water waste and soil nutrient loss; Monitoring nitrogen, phosphorus, potassium, dissolved oxygen, PH value, etc., can fully grasp soil nutrients, guide rational fertilization, improve yield and reduce environmental problems.
Soil moisture monitoring data is an important basis for service decision-making and production guidance. It provides a foundation for drought grade division, calculation of effective utilization coefficient of irrigation water, etc., helps put forward agricultural measures such as timely sowing and drought-resistant irrigation, and is of great significance to improve irrigation efficiency.
