Introduction: Technical innovation needs of grain storage management

In the grain industry chain, the storage link is the core node to ensure the quality of grain and reduce the loss. The traditional storage mode relies on manual inspection and empirical judgment, which has some problems, such as lagging temperature and humidity control, untimely pest warning and so on. As a comprehensive enterprise integrating planting, purchasing, processing, warehousing and sales, Yaduo Grain Management Co., Ltd. has realized the transformation from "experience management" to "data driven" by introducing intelligent storage system, providing technical guarantee for food security.

Technical layout: multi-dimensional sensor network and AI decision system

Yaduo's intelligent storage system takes "perception-analysis-execution" as its core architecture, and builds a sensor network covering the inside of the grain pile by deploying temperature and humidity sensors, gas concentration monitors, insect detection lights and other equipment. For example, in wheat storage, the system can monitor the temperature gradient of the grain pile in real time (accuracy ± 0.5 ℃), and automatically trigger the ventilation equipment when the local temperature exceeds 25 ℃ to avoid fever and mildew. Based on historical data and real-time parameters, the AI decision-making system dynamically adjusts the ventilation frequency and the amount of chemicals to reduce the incidence of pests by 40%.

Key technical parameters and equipment selection

1. Sensor accuracy: The temperature and humidity sensor adopts industrial SHT31 chip, with a range of -40 ℃ ~ 125 ℃ and a humidity resolution of 0.04 RH; The gas concentration monitor can detect gases such as CO₂ and PH with a detection limit of 1ppm.
2. Actuator: Axial flow fan is selected for ventilation equipment, with air volume ranging from 5000 to 20000 m/h, and accurate air control is realized with electric valve. Micro peristaltic pump is used for drug delivery, and the error of single delivery volume is ≤ 0.1ml.
3. Data transmission: LoRa wireless communication technology is adopted, the transmission distance is up to 1.5km, the power consumption is as low as 50mA, and the long-term operation of battery-powered equipment is supported.

Application Case: Intelligent Transformation of Corn Storage

In a 5000-ton corn storage project, Atour achieved the following optimizations through intelligent systems:
1. Energy consumption reduction: traditional ventilation needs to be manually turned on and runs for 8 hours a day; The intelligent system automatically adjusts according to the temperature of the grain pile, shortening the average daily operation time to 3 hours and saving about 120000 degrees of electricity annually.
2. Quality improvement: Through precise temperature control, the annual increase in corn fatty acid value is reduced from 15mgKOH/100g to 8mgKOH/100g, reaching the first-class grain standard.
3. Loss reduction: Pest warning advance rate increased from 3 days to 7 days, with the precise delivery of chemicals, the proportion of insect particles decreased from 2% to 0.5.

Technology Extension: From Warehousing to Digital Collaboration of the Whole Industry Chain

Yaduo will connect the intelligent storage system with the Internet of Things equipment at the planting end and the automated production line at the processing end, forming a closed loop of data for the whole industry chain. For example, by analyzing the quality change data of grain in storage, the fertilization scheme at the planting end is optimized in reverse. According to the humidity data of grain in storage, the processing end dynamically adjusts the drying process parameters to increase the rice yield by 2%.

Conclusion: A new technology-driven paradigm for food security

The practice of Yaduo Grain Management Co., Ltd. shows that the intelligent storage system can not only improve the efficiency and safety of the storage link, but also feed the whole industry chain through data, and promote the development of the grain industry in the direction of refinement and intelligence. In the future, with the integration of 5G, edge computing and other technologies, intelligent warehousing will further realize "unmanned" management, providing stronger technical support for ensuring national food security.
