Design of the Anti-Omission Shared Lockers System Based on the Single Chip Microcomputer

摘要

In recent years, shared lockers have been widely used in supermarkets, libraries, exhibition halls and other places due to their features of high safety, reliability and convenience. However, existing lockers, because of their depth, tend to lose small items and are difficult to find. In addition, traditional barcode lockers are also easy to lose barcode. Based on this background, this paper presents a design scheme of the system for anti-omission of the shared locker based on the single chip microcomputer (SCM). In the scheme, STC89C52 single chip microcomputer is used as the main control chip, and the pressure sensor is used to detect whether there are things in the shared lockers and send the information to STC89C52 single chip microcomputer to achieve anti-omission function. Supplemented by relevant keyboard module, which is the input module of the system. Furthermore, display module and voice module are the output module of the system. The fingerprint module is used to input the user's information and used the information to open the door of shared lockers. GSM (global system for mobile communication) module is used to get help from administrator when the user needs to help, and so forth. This system can realize the function of preventing omission and it is simple to operation, high security, easy to manage by the administrator.
