The linkage between smart control valves and soil moisture sensors essentially relies on a closed-loop logic of "real-time sensing - precise decision-making - automatic execution" to address the pain points of "experience-based judgment and manual operation" in traditional irrigation/fertilizer-water management. It provides an efficient, water-saving, and intelligent solution for scenarios such as agricultural planting, landscape maintenance, and greenhouse cultivation. The following details its core competitiveness from three dimensions: основные функциональные преимущества, преимущества пользовательской ценности, и преимущества адаптации сценариев.
Traditional smart valves can only realize "timed on/off" or "remote manual control". However, after linking with soil moisture sensors, the system can dynamically adjust based on the actual soil moisture, achieving "on-demand supply". The core functional advantages are reflected in the following four aspects:
Датчики влажности почвы могут быть установлены непосредственно в корневой зоне культуры (например, на глубине 20-30 см для полевых культур, 10-15 см для тепличных овощей) для сбора в режиме реального времени ключевых данных, таких как объемное содержание воды в почве (VWC) и водный потенциал почвы (с точностью ±1%), которые затем передаются на интеллектуальный контроллер клапана по беспроводным (LoRa/NB-IoT) или проводным каналам.
- Comparison with traditional methods: It avoids subjective errors caused by "watering based on weather" or "judging dryness/wetness by hand", especially solving the misjudgment problem of "dry surface but wet deep layer" in clay soil or "wet surface but dry deep layer" in sandy soil. This ensures that the sensing data highly matches the actual water demand of crops.
Soil moisture "threshold values" can be preset for smart valves (e.g., turning on irrigation when the soil moisture content of corn at the seedling stage is below 18%, and turning it off when it exceeds 25%). When the sensor detects that the data exceeds the threshold, the controller will automatically send instructions to the smart valve to complete the whole process of "valve opening - water supply - valve closing" without manual intervention.
- Key value: It addresses the pain points of "labor shortage and large management radius" in agricultural production (e.g., large-scale farms, orchards) and the scenario needs of "nighttime water supplement and unattended management on holidays" in landscape maintenance. This reduces labor costs while avoiding "missed irrigation and delayed irrigation".
Связанная система может гибко регулировать пороговые значения и продолжительность полива в соответствии с нормами потребности в воде для культур на разных стадиях роста:
- Example: Tomato seedlings have low water demand, so the threshold is set to "15%-20%" with a single irrigation duration of 15 minutes; during the fruiting period, the water demand is high, so the threshold is adjusted to "18%-25%" with a single irrigation duration of 30 minutes.
- Comparison with timed irrigation: It avoids "watering on time regardless of soil dryness/wetness", reducing water waste (field tests show that the linked system saves 30%-50% more water than timed irrigation). At the same time, it prevents soil compaction or crop root rot.
The system not only enables "automatic execution" but also records real-time information such as soil moisture data, smart valve on/off time, and irrigation duration. It generates reports (e.g., "Soil moisture change curve of a certain plot in July" and "Weekly irrigation water consumption statistics") through the cloud platform.
- Core function: It provides data support for users to optimize irrigation strategies (e.g., adjusting thresholds in different seasons based on historical data) and meets the "precision management" needs of large-scale planting (e.g., multi-plot comparison and correlation analysis between yield and soil moisture).
From the perspective of the manufacturer’s customers (e.g., farmers, landscape companies, and greenhouse operators), the linked solution can directly bring "quantifiable" value, which is mainly reflected in three aspects:
Different application scenarios have different demands for "soil moisture - valve linkage". The linked solution can adapt to diverse scenarios by flexibly adjusting sensor types, valve parameters, and control logic, enhancing the product’s market competitiveness:
- Ключевые моменты адаптации: Выбирайте датчики влажности почвы, устойчивые к воздействию солей и щелочей и механическим повреждениям (например, датчики из нержавеющей стали). Интеллектуальные клапаны поддерживают большой расход (например, калибр DN50-DN100), чтобы удовлетворить потребности в орошении больших площадей;
- Core value: Solve the problem of "scattered plots and long irrigation cycles" and realize "on-demand irrigation", which is especially suitable for large-scale planting bases.
- Ключевые моменты адаптации: Датчики поддерживают высокую точность (±0,5%) и могут контролировать влажность почвы на разных глубинах корневой зоны сельскохозяйственных культур; интеллектуальные клапаны поддерживают малый расход воды (например, калибр DN20-DN32) для адаптации к местным методам орошения, таким как капельное орошение и микродождевальное орошение;
- Core value: Precisely control the humidity in the greenhouse to avoid diseases caused by high humidity. At the same time, it can be combined with the fertilizer-water integration system to realize the coordinated control of "water - fertilizer - soil moisture".
- Ключевые моменты адаптации: Датчики поддерживают низкое энергопотребление (работают от батарей, срок службы 1-2 года). Умные клапаны поддерживают сегментированное управление (например, полив в разные периоды времени на одном участке);
- Core value: Address the pain points of "large maintenance area and difficult manual inspection", especially suitable for scenarios with high requirements for landscape effects such as urban green belts and golf courses, avoiding vegetation withering or over-watering.
- Основные моменты адаптации: Датчики можно закапывать в глубокую почву (например, на глубину 30-50 см для плодовых деревьев). Интеллектуальные клапаны поддерживают двойные режимы по времени и влажности почвы (например, приоритетный полив по влажности почвы в период цветения и комбинированный с дополнительным поливом по времени в период роста плодов);
- Core value: Meet the demand of cash crops for "large differences in water demand at different growth stages", improve yield and quality, and increase planting income.
