Description

一种不同频率电台进行音频通信的系统
技术领域
本发明涉及通信领域，具体为一种不同频率电台进行音频通信的系统。
背景技术
无线电台之间要进行音频通信(即电台喊话)，则必须要求电台的频率一致(在同一个频段)，跟收音机/收音台类似，需要调制对应的频率才可能接受到音频数据。电台之间进行音频通信，必须通过串口来控制PTT。因为电台之间的通信时半双工的，即：一方讲，另一方听；电台双方不能同时讲话，按下PTT键的一方可以讲话，只能当一方的PTT键松开后，另外一方才可以按下PTT键再讲话。图1是现有技术的不同频率的电台无法通过天线进行音频通信的示意图，其中电台A和B的频率相等（如44KHZ），电台C和D的频率相等（如110KHZ），而频率不同的电台之间无法进行音频通信。因此有必要进行改进。

参照图2，是本发明实现不同频率电台的互通的实现原理示意图。其中，电台A和B的频率相等（如44KHZ），电台C和D的频率相等（如110KHZ），其实现互通的步骤为：
使用前，用户分别将音频线和PTT控制的串口线连接好；
并将音频端口对应配置下发到业务配置模块，即需要互通的两个音频端口对应关系；
音频端口检测模块检测到互通的两个音频端口中的一个接收到音频数据，则上报给主控模块；
主控模块接收到音频端口检测模块上报的消息，根据上报内容里携带的端口信息，向串口控制模块下发关闭该端口对应的PTT口，并打开与该端口进行互通的端口对应的PTT口；
如检测到第一音频端口有音频数据，则关闭第一音频端口对应的PTT口；打开第二音频端口对应的PTT口；

电台互通系统至少提供两个以上的音频口、两个以上的串口，音频接电台的音频线，串口接电台的PTT控制线。
参照图4，是本发明一实施例的示意图。电台接收到音频信号，通过音频线传送到电台互通系统设备的音频端口；
当检测到有音频信号时，通过配置信息找到对应的串口，下发打开PTT命令。
接收到音频信号的音频端口通过时隙通道同时将音频信号传送到对应的另外一个音频端口，然后经过与之连接的音频线传送到对应的电台音频口。

检测到音频信号的端口，启动检测定时器，当定时器超时还未接收到音频信号，则向对应的串口下发关闭PTT口的命令。(如果没有关闭PTT机制，电台一直处于向外发射状态，无法接收数据，故设置10秒的音频信号检测机制)。
