摘要:

針對模擬訓練系統中語(yǔ)音通信的應用需求,提出了一種基于TCP/IP協(xié)議在局域網(wǎng)內進(jìn)行IP語(yǔ)音通信的實(shí)現方法;分析了該語(yǔ)音通信系統的組成結構和工作原理,設計了以微處理器STM32F103ZET6為核心、以語(yǔ)音編解碼芯片VS1053B為驅動(dòng)的語(yǔ)音控制電路,SD卡連接電路和電源電路；移植了UCOSⅢ嵌入式實(shí)時(shí)操作系統增強控制系統的實(shí)時(shí)性和穩定性,采用FatFs文件系統管理SD卡存儲設備;利用串口服務(wù)器實(shí)現串口數據與以太網(wǎng)數據的快速交換,完成模擬訓練系統局域網(wǎng)的搭建,實(shí)現基于TCP/IP協(xié)議的穩定高效的IP語(yǔ)音通信。采用.NET Framework的Socket模塊和Winform模塊設計了上位機模擬網(wǎng)控軟件;測試結果表明,系統穩定可靠、擴展性強,語(yǔ)音通信質(zhì)量滿(mǎn)足模擬訓練使用要求。

Abstract:

Aiming at the application of voice communication in simulation training system, a method of IP voice communication based on TCP / IP protocol in LAN is proposed. The composition and working principle of the voice communication system are analyzed, the voice control circuit driven by the microprocessor STM32F103ZET6 and the speech codec chip VS1053B is designed, the SD card connection circuit and the power supply circuit are also designed.The embedded real time operating system UCOS Ⅲ is transplanted in order to enhance the real-time and stability of the control system, and the FatFs file system is used to manage the SD card storage device. The serial port server is used to achieve rapid exchange of serial data and Ethernet data and build the LAN of simulation training system, IP voice communications based on TCP/IP protocol is accomplished stably and efficiently. The .NET Framework's Socket module and Winform module are used to design PC's simulation network control software.Test results show that the system is stable、reliable and scalable, voice communication quality is good to meet the requirements of simulation training.
