An electronic fruit system specifically designed for walnuts, integrating multi-point vibration parameter collection with simulated fruit abscission functions was developed to investigate the conditions under which walnuts detached from the tree. The development process involved creating a dynamic model that described the interaction between walnuts and the tree, establishing criteria for walnut abscission, and designing a device along with an indoor experimental platform to test the system’s capabilities. The reliability and functionality of the system were confirmed through indoor experiments, which demonstrated its effectiveness in accurately collecting and analyzing vibration data from walnuts. Subsequent outdoor field tests were conducted to evaluate the system’s performance in a real-world setting. During these tests, the electronic fruit system collected synchronized multi-point vibration data, providing insights into the dynamics of walnut detachment. The data analysis revealed that during vibration-assisted harvesting, walnuts predominantly experienced normal vibrations, with the normal force exerted on the walnuts being the primary factor leading to their detachment from the tree. The system’s integration of multi-point synchronous measurement and simulated abscission functionality offered significant advantages for studying walnut drop conditions. Moreover, this technology showed promise for application in automated harvesting of other crops, potentially revolutionizing agricultural practices by enhancing efficiency and effectiveness in crop management. By providing detailed and actionable data, the electronic fruit system not only advanced understanding of walnut abscission but also contributed to the broader goal of improving harvesting techniques and practices across various agricultural sectors, making it a valuable tool with extensive future applications in the industry.
