基于STM32F103的无主机通信系统的设计

针对目前工矿企业生产调度通信系统呼叫方式单一、强噪声环境下语音通信质量差以及缺少维护管理等问题,提出了一种基于STM32F103的无主机通信系统解决方案。本系统对现有无主机通信系统的呼叫方式进行优化,增加了选呼、强插、强拆和监听功能;采用DSP语音处理技术,提高了系统的抗噪声性能;通过中继器实现用户终端与公共交换电话网络用户的通信;通过管理控制器、管理终端对整个系统进行管理与控制;采用有限用户多信道共用理论与不同参数下信道数优化配置方案对系统参数进行配置。实验表明,所设计的系统可靠性和实用性较高,呼叫针对性强,通信质量较好。

Design of Non-central-switch Calling System Based on STM32F103

Focusing on the problems existing in current industrial and mining enterprise production dispatching communication system which includes the single of calling mode, the poor quality of communication in strong noise environment, the lack of operating and managing, a solution of non-central-switch calling system based on STM32F103 is proposed. The system optimizes current non-central-switch calling system and increases the functions of forced-inserting, forced-releasing and supervising. The DSP voice-processing technology is used to improve the anti-noise performance of user terminals. The communication between user terminals and PSTN users can be realized through the repeater. Besides, the management and control of the entire system can be realized through the management controller and management terminal. The system parameters can be configured according to wired multi-channels user sharing theory and channel-number optimized configuration scheme under different parameters. The experimental results show that the designed system with a high reliability and practicability, a strong call pertinence, a good communication quality.
