分布式无线信息发布平台的设计与实现

提出了一种基于短消息的分布式无线信息发布平台,该平台由控制终端和多个短信收发器组成.设计了网络进程间一种基于消息队列异步通信机制和基于TCP/IP的"心跳"检测机制.在控制终端实现了按照消息优先级分级进行排队、管理和消息均衡分发的机制,以及对每条消息发布状态的"实时"跟踪,在发送失败或者发送超时的情况下能将其成功转移到另外一个短信收发器进行发送,并分析了消息队列达到平衡状态的充分条件.介绍了短信收发器发送短信和接收短信的过程,提出无线信息发布平台具有良好可扩展性,可根据业务量增加而扩展短信收发器数量,能广泛应用到布置有线网络有困难的场所.

Design and realization of distributed wireless information release platform

One kind of distributed wireless information release platform is brought forward,which is composed of the terminal control and several SMS(short message service) transmitter and receivers.The mechanism of message queue asynchronous communication between net processes beside 'heartbeat' based on TCP/IP protocol is designed.The terminal control realizes message queue queuing,management,ordering by priority and dispatching according to equality arithmetic,and also tracks the status of every message been sen-ding and transfers it to another SMS transmitter when finding it has been transmitted unsuccessfully or has been beyond the deadline;the plenty condition of the balance of message queue status is analyzed.At last,the process of transmitting and receiving SMS are introduced.The platform can increases SMS transmitter and receivers according to increasing information.Importantly,it can be applied to places where it is difficult to set lineate net.
