智能快递系统的设计及其辐射干扰与传导分析

Design of An Intelligent Express System and Analysis of Its Radiation Interference and Conduction

采用模块化的方法设计了一款实用性强、成本低、操作简单的智能快递系统。功能包括:短消息的自动发送,通过键盘和面板决定功能的确定与信息的输入、柜门的开启。系统以STC89C58RD+为主控制器,用键盘模块控制信息的输入,用LCD1602控制信息的显示,单片机控制GSM模块发送短信验证码。系统电磁干扰测试表明,系统在低频和高频段的辐射干扰和传导干扰均符合国家有关的电磁兼容标准。

A intelligent express system, with high practicability, low cost and simple operation, is designed by modularization method. The functions include automatic sending of short messages, determination of functions through keyboards and panels, input of information and opening of cabinet doors. The system uses keyboard module to control the input of information and LCD1602 to display the information. Electromagnetic interference tests show that the radiation interference and conduction interference in low and high frequency bands of the system are in line with the relevant national electromagnetic compatibility standards.
