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.
