Design of Control System for Intelligent Self-Service Cabinet

The Intelligent Self-Service Cabinet is an important device which developed for convenient delivery of fresh distribution fields. In order to meet the needs of the users, this paper is based on Cortex-M3 to cater the design requirements of the Intelligent Self-Service Cabinet. The Host-Controller communicates with the Sub-Controller by RS-485 Bus. Once the Sub-Controller received the instructions from the Host-Controller, it can set the communication address and display data; in addition, it can also open and close all the cells, or detect temperature and adjust the temperature; what is more, it can use the infrared sensor to detect items and so on. All of those are by means of the peripheral module circuit. When we put them together, thereby we can use the Sub-Controller to control the Intelligent Self-Service Cabinet. Introduction Especially the last mile of the distribution about fresh product has been difficult to break through the technical bottleneck, which gives rise to the sale of fresh electricity supplier has brought a great deal of trouble. In view of the above shortcomings, smart fresh from mentioning cabinet system provides a cold storage type self lockers in machinery from mentioning cabinet is composed of several independent and a box door closed container, with refrigeration equipment and control system of intelligent cabinets from mentioning fresh complete from mentioning cabinet system, can from the cold chain storage on the locomotive after fresh products, and can provide consumers with fresh products 24 hours pick up service, avoid the attendant direct distribution to consumers in the process, so as to solve the logistics distribution chain of fresh products distribution problem, meet the development needs of the new logistics system with low energy consumption. Design of Control System In order to meet the needs of the customers, the intelligent Self-Service cabinet should be able to communicate with the master and slave logic based on the realization of the function of the main controller and the controller. In order to facilitate the function of intelligent self extracting cabinet, flexible configuration and routing, installation and maintenance, the design of the system adopts master-slave bus system architecture. The overall design block diagram of the system is shown in figure 1. A set of intelligent Self-Service cabinet is provided with 10 sub cabinets, and is controlled by a sub controller, and the main controller can be connected with a plurality of sub controllers through the field bus, so as to realize the convenient module expansion function. The main controller by combining storage module, voice module, card module, barcode scanning module, wireless communication module, keyboard module, LCD module main control circuit, and then realize the local storage, voice broadcast, IC card identification, barcode scanning, wireless communication, human-computer interaction and other functions. The utility model is provided with a 10 way cabinet control port, and the corresponding 10 sub cabinets are respectively controlled. Each sub controller for detecting and controlling temperature and humidity of each cell, infrared object detection and gated lock gate, data transmit through Fieldbus with the main controller, without sensor signal line is connected to the main controller, 2nd International Conference on Automation, Mechanical Control and Computational Engineering (AMCCE 2017) Copyright © 2017, the Authors.
