Design of Distributed Intelligent Waste Sorting and Dropping System Based on RS-485

In response to the problem of complicated structure and poor scalability of waste sorting and dropping systems in the market. Combined with distributed measurement and control technology, an intelligent garbage sorting and dropping system is designed. The system is based on RS-485 bus, and the framework adopts the data interaction method of one master station and multiple slave stations. The master station is mainly used for communication and data processing, and realizes human-computer interaction with users through the touch screen; it connects to the cloud through the DTU to obtain user information and upload the points information to the cloud server after the garbage is put out, so as to fulfill the record of user’s put-out information; The slave station is mainly used to control the movement of the bin door at the drop port and the acquisition of the waste weight. The experimental results show that the system operates stable and satisfies the needs of environmental protection enterprises. Compared with the traditional intelligent sorting and putting station, the system is more expandable and the free combination of the drop system is more convenient, which achieves the intelligent construction of waste separation and disposal.
