摘　　要：对通讯能力和效率较差的农村来说,电子显示屏和大喇叭是气象预警信息最有效的发布手段。为实现海南突发事件预警信息的及时发布,为农村及时提供气象预警信息,海南省气象局设计开发了基于大喇叭、显示屏的气象信息发布监控系统。该系统整合了现有的预警信息发布手段,与电子显示屏、高音喇叭等发布手段实现了对接,可多手段一键式发布气象灾害预警信息、气象服务信息、气象为农信息。该系统采用C/S三层架构和MVC设计模式来构建,采用跨平台应用程序框架Qt开发,基于TCP协议和FTP协议实现系统内的相互通信。同时为了实现系统核心业务“多手段发布”功能,系统实现了多线程、多队列的信息多手段一键式发送机制,充分利用服务器硬件资源提高信息的发送效率。该系统目前已经投入使用,结果表明,该系统能够及时有效地通过电子显示屏和大喇叭等发布渠道向公众发布气象预警信息,并实现了电子显示屏、大喇叭等多种手段信息发布的全程监控,同时具有较高的稳定性和可靠性。For the rural areas with poor communication ability and efficiency,electronic display screen and loudspeaker are the most effective means of releasing meteorological early warning information.In order to release the early warning information of Hainan emergencies in time and provide meteorological early warning information for rural areas in time,Hainan Meteorological Bureau has designed and developed a meteorological information issuing and monitoring system based on loudspeaker and display screen.The system integrates the existing means of issuing early warning information,and realizes the docking with electronic display screen,loudspeaker and other means of issuing.It can publish early warning information of meteorological disasters,meteorological service information and meteorological information for agriculture by multiple means and one key.The system is constructed with C/S three-tier architecture and MVC design pattern,developed with Qt,a cross-platform application framework,and based on TCP and FTP to achieve mutual communication within the system.At the same time,in order to realize the“multi-means publishing”function of the core business of the system,the system implements a multi-threaded,multi-queue,multi-means and one-key information transmission mechanism,and makes full use of the hardware resources of the server to improve the efficiency of information transmission.The system has been put into use at present.The results show that the system can timely and effectively release meteorological warning information to the public through electronic display screen and loudspeaker,and realize the whole process monitoring of information release by electronic display screen,loudspeaker and other means.At the same time,the system has high stability and reliability.
