| Abstract: | Fruit and vegetable sorting is an indispensable part of postharvest fruit and vegetable production, and the automatic production line with programmable logic control technology as the core provides a new way for the intelligent development of modern agriculture. In the present study, the technologies of data acquisition, data processing, wireless communication, intelligent control and so on were deeply integrated, and a remote-controlled intelligent sorting mechanism for fruit and vegetable was studied, in order to improve the efficiency of fruit and vegetable sorting and reduce the labor cost of local sorting. The remote control sorting schemes were investigated via programmable logic controller(PLC) automatic data acquisition and mechanical control method and distributed network control method based on .NET core architecture, aiming to realize high-speed remote on-line intelligent sorting of fruit and vegetable coordinating appropriate sugar content-quality model. The control strategy and sorting accuracy were simulated based on testing the software and hardware scheme of the sorting technology. Results showed that, compared with the traditional fruit and vegetable sorting technology, this system had advantages in system cost, reaction speed, sorting accuracy, management efficiency, etc. and the fruit and vegetable sorting accuracy could reach to more than 93%, which could realize remote fault diagnosis, save labor cost, and presented the values of generalization and application. |
