Design of mine-used audio and video linkage software
-
摘要: 针对目前矿井融合调度通信系统中音频通信和视频通信缺乏有效联动，无法支撑调度员进行高效音视频联动通信的问题，设计了一种矿用音视频联动软件。软件中间件通过OCP协议实时获取调度通信主机终端状态，数据处理模块判断电话状态，并将联动视频信息通过消息队列RabbitMQ发送给客户端，客户端接收数据处理模块传送的合法指令，控制视频终端开启和关闭。测试结果表明，该软件运行稳定，安装简便;通过Web配置管理平台，用户可以方便地对电话、视频信息进行管理，同时对二者的对应关系进行配置;对每个客户端绑定的调度电话，当该电话主叫或者被叫时，均可在屏幕上显示对端电话绑定的摄像仪信息，视频信息显示流畅，可在1 s内响应，满足用户的实时性要求。Abstract: In view of the lack of effective linkage between audio communication and video communication in current mine integrated dispatching communication system, it cannot support dispatcher to proceed efficient audio and video linkage communication, a mine-used audio and video linkage software was designed. The software middleware obtains status of terminal of scheduling communication host in real time through OCP protocol, the data processing module judges the phone status, and sends the linked video information to the client through the message queue RabbitMQ. The client receives the legitimate instructions sent by the data processing module and controls the opening and closing of the video terminal.The test results show that the software is stable and easy to install; through the Web configuration management platform, users can easily manage the telephone and video information, and configure the corresponding relationship between the two;for each scheduling phone bounded by client, when the phone is calling party or called, the camera information of phone of the other party can be displayed on the screen. The video information can be displayed smoothly and the response can be made within 1 s,which meets real-time requirements of users.
