Description

Real-time Silo Inventory Measurement System The present invention relates to a real-time silo inventory measurement system, and more specifically, to a real-time silo inventory measurement system capable of managing inventory in real time by installing a leveling device inside a silo constructed in a rice processing plant. A rice processing plant is a facility that integrates the drying and milling processes of paddy rice in one location. Harvested paddy rice is dried and stored at a constant temperature and humidity, and then processed into white rice through the milling process. This process allows for efficient processing while maintaining the quality of the paddy rice, thereby playing a role in increasing agricultural productivity and the quality of rice provided to consumers. The main functions of a comprehensive rice processing plant include drying, storage, milling, packaging, and shipping processes. The drying process involves drying harvested paddy rice to an appropriate moisture content to enable long-term storage. The storage process involves storing the dried paddy rice in grain warehouses and managing temperature and humidity to prevent spoilage. The milling process involves removing the husks from the paddy rice to produce white rice, which is a critical step in managing rice quality and hygiene. The packaging and shipping process involves packaging the milled white rice so that consumers can conveniently purchase it and shipping it to the market. In addition to these, some comprehensive rice processing plants can enhance the efficiency of rice processing by performing various additional processes, such as quality inspection, washing, and the disposal of post-processing by-products. Typically, silos are installed in comprehensive rice processing plants for the long-term storage of rice. Silos serve to protect grain from the external environment and enable efficient storage and shipment. Their key features include airtightness, which prevents contact with outside air to reduce the effects of moisture, pests, and mold while maintaining grain freshness; temperature, humidity, and ventilation systems that automatically regulate and manage the internal grain conditions; and conveyor systems that automatically fill and discharge grain. However, in conventional rice processing plants, there is a persistent problem of rice loss during the drying and storage processes of the comprehensive processing. This occurs not so much due to a lack of management, but rather because the storage conditions of the silos within the processing plants—that is, inventory checks—are not properly conducted. Conventional methods for measuring inventory and storage volumes in general rice processing plants involve manual labor to perform leveling and actual measurements, which has the drawback of being highly inefficient and potentially causing safety issues. In addition, there is a problem in that when rice is discharged from a silo, the rice at the discharge port becomes sunken, making it very difficult to measure and manage the amount of grain released and the inventory. Furthermore, conventionally, since the silo operator had to go directly to the site to check the temperature of the rice and manage the temperature and moisture content by operating agitators, blowers, etc., there is a problem in that immediate response is impossible when the operator is not present at the site. The matters described above as background technology are intended solely to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art.
