本文提出了一种新的供广大用户缴纳水费、暖气费等公共事业费用的缴费方式,介绍了基于GSM短信的缴费系统的设计和实现。此缴费系统以GSM网络为通信平台,通过SMS实现了用户以“空中充值”的形式缴纳费用。短信收发子系统是数据采集终端和后台处理系统通信的门户,它采用状态机机制来实现短信的读取、删除、发送三个功能,并且利用互斥变量来实现对短信接收队列和短信发送队列的互斥访问。缴费业务处理平台通过数据库实时监控子线程来实现对手动处理业务信息表和自动处理业务信息表的实时监控,调用各个功能模块实现用户缴费、用户余额查询、对账等功能。
This paper presents a new payment method for public utilities such as water fee and heating fee, and introduces the design and implementation of payment system based on GSM SMS. This payment system to GSM network as a communication platform, through SMS to achieve the user to “over the air recharge” in the form of payment. SMS transceiver subsystem is the data acquisition terminal and background processing system communication portal, which uses the state machine mechanism to read, delete, send SMS function, and the use of mutually exclusive variables to achieve the SMS receiving queue and SMS sending queue Mutual exclusion visit. The payment service processing platform realizes the real-time monitoring of manually processing the business information table and automatically processing the business information table through the real-time monitoring sub-thread in the database, and invokes various function modules to realize the functions of user payment, user balance inquiry and reconciliation.
