该设计由STC15F2K61S2芯片作为系统的控制核心，外部扩展12864显示屏、矩阵键盘、GSM模块、蜂鸣器、直流继电器和电控锁等器件。该系统可以大大节省快递员的工作时间，还可以方便取件人取件。快递员首先要输入工作编码，验证正确后输入收件人手机号，此时系统产生验证码并打开箱门。当快递柜箱门关闭后会自动向收件人发送短信告知取件验证码，取件人通过输入正确的验证码可以取件。这样大大节省了快递员打电话或发短信通知取件的时间，提高了快递员的工作效率，减轻了工作压力，而取件人也不需要为了取快递而专门等待很长时间。(The design is made up of STC15F2K61S2 chip as the core of the system. It expands 12864 display screen, matrix keyboard, GSM module, buzzer, DC relay and electronic control lock. The system can greatly save the working time of the courier, and also facilitate the taking of a person. The courier must first enter the work code, verify the correct input after the recipient's mobile phone number, at this time the system generates verification code and open the box door.

This saves the courier call or send SMS notification to take time, improve the courier work efficiency, reduce the work pressure, and take people don't need to take delivery and wait for a long time.)
