Description

Rail Electric Gantry Crane for Paddy Field Work System The present invention relates to agricultural automation, and more specifically to a rail-based electric crane system capable of automatically performing various tasks (e.g., plowing, fertilizer application, sowing, watering, weed removal, etc.) in a paddy field. This system is designed to perform each task with precision, using cameras to recognize and remove weeds and other crops via object detection technology. Utilizing technologies such as Convolutional Neural Networks (CNN), Roboflow, and YOLO, it monitors the condition of the paddy fields in real time and maximizes the efficiency of each task. This system can reduce the burden on the aging agricultural population and maximize operational efficiency by increasing the accuracy and speed of each task. Traditional paddy farming operations consume a significant amount of manpower and time, while limiting access to machinery. These tasks are physically demanding and lead to labor burnout due to repetitive demands. In particular, major operations such as fertilizer application, sowing, and watering require substantial labor, which tends to result in lower crop productivity. The aging of the agricultural workforce is increasing the need for automation systems. The unique environment of rice paddies, characterized by mud and water, makes the use of conventional agricultural machinery difficult, leading to problems such as wheels easily slipping or the machinery becoming submerged. In such conditions, efficient operation of agricultural machinery is challenging, resulting in reduced productivity. Therefore, there is a demand for new automation technology capable of performing large-scale agricultural operations stably and efficiently, while also preparing for future food shortages. This invention was designed to address these needs and provides a power supply method that considers operational stability and energy efficiency. Figure 1 is a drawing showing the overall structure of an electric crane that moves along a rail installed on the edge of a rice paddy. This drawing includes each element of the electric crane and the crane moving along a power supply coil on the edge of the rice paddy to perform various agricultural tasks. High-voltage power supply coils (5) are installed along the edge of the rice paddy, and crops are managed using an electric crane (2) that moves along them. The rail (1) is made of a corrosion-resistant material and is designed to be used for a long time even in the special humid environment of the rice paddy, and the crane (2) moves stably along the rail (1) to perform each task. The work device (2) uses a fixed work module (3) to perform various tasks such as spreading fertilizer, sowing seeds, supplying water, and removing weeds. Each work module (3) is designed to analyze the discussion status in real time and perform the optimal work, thereby increasing the accuracy and efficiency of the work. The fertilizer spreading module detects the condition of the paddy field and evenly sprays an appropriate amount of fertilizer. The sowing module is designed to plant seeds accurately at regular intervals. The water supply module detects the moisture status of the paddy field in real time and automatically supplies the required amount of water. Each work module (3) is linked with the central control system (4) to optimize and perform work according to the discussion status and environmental changes. The central control system (4) monitors the work status of each work module (3) in real time and automatically sets the optimal work schedule. Based on data collected by the camera, the central control system (4) monitors the location and work status of each crane in real time and optimizes the work schedule. Power is supplied via electromagnetic induction through a fixed work module (4) and a central control system (6), thereby allowing the crane to continuously receive power along the rice paddy and perform work. The crane moves smoothly along the rail (1) using a current collection coil (7) and performs the necessary work within the work area. The crane (2) generates powerful torque through high-voltage power to efficiently move heavy work modules (3). This provides more powerful performance than conventional work devices and enables work on various terrains. The work module (3) can be height-adjusted through a gearbox installed on the central frame, thereby automatically adjusting its height to suit various terrains. The gearbox is connected to an electric motor, allowing it to quickly respond to changes in terrain and perform work at an optimal height. The gearbox is connected to an electric motor, allowing for precise control of the position of the work module (3). This enables the module (3) to perform work at the required height and to respond quickly to changes in the terrain of the field. The crane (2) is supplied with power through electromagnetic induction using a power supply coil
