基于SIM800C的短信投送系统的设计与实现

Design and Implementation of a Software for Delivering SMS with SIM800C

虽然大多数企事业单位建立了内部管理信息系统或电子邮件系统,基本实现了内部信息及时交流。但是,员工不会一直关注内部信息系统的通知,以及在外出途中、参加会议等特殊情况下,无法使用内部管理系统时,一些内部信息无法及时传达。在该文中提出了一个基于短信的通知发送软件,采用SIM800C通信模块,能单次或批量生成并发送短信息,具有较好的即时性和保密性。该软件使用C#开发,实现软件控制SIM800C模块按要求发送短信,能预约发送时间,并记录发送状态,支持对发送失败的信息进行延时重发。该软件具有方便、实惠等特点,能满足各种中小企业发布重要信息的需求。

Although most enterprises and institutions have established their internal MIS or e-mail system,basically realizing the timely exchange of internal information,employees will not always pay attention to the messages in the internal MIS.Some internal information cannot be delivered in time when employees are unable to use the internal MIS in special circumstances such as on the way out and attending meetings.A software for delivering SMS,which uses SIM800C communication module to delivering message one-by-one or in batch,is proposed in this article,and it has the advantage of timeliness and reliability.The software is developed with C#.It manipulates SIM800C module to send short messages according to the requirements,and it records the sending time and the sending status.It can deliver the failed messages by delayed retransmission.The software is convenient and affordable,which can meet the needs of various small and medium-sized enterprises to release important information.
