The Design of Multi-channel Wireless Data Communication System For Local Space

摘要:

通过对无线数据通信及信号处理的研究,设计并实现了一种面向局部空间的多通路无线数据通信系统。本系统利用MTTM协议和ShockBurstTM射频模式并结合ARM处理器对各通道的信息源进行信道解码、信息获取、信息校验、信息匹配和传输等处理。实现在一定空间范围内对多个外部监测设备的无线连接。通过不同的通道获取来自不同设备不同通信协议的数据,确保信息能够实时、稳定、有效的传输。通过实验测试,该系统可以实时、稳定地获取外部蓝牙的多种监测数据以及外部NRF射频器件的监测数据；也可以从电脑端实时、稳定地获取数据,进而控制已连接的外部设备。该系统具有可扩展性,可以通过更换或增加不同的通信协议模块对通信方式进行扩展使其支持更多的无线通信协议。

S：Through the research of wireless data communication and signal processing, a multi-channel wireless data communication system oriented to local space is designed and implemented. Based on the MTTM protocol and the ShockBurstTM radio frequency model, the channel is decoded and the information is acquired, verified and matched in the ARM processor. Such the system finally achieve the wireless connection of multiple external monitoring devices in a certain space. Such the system finally achieve the wireless connection of multiple external monitoring devices in a certain space. The data obtained from different communication protocols and devices ensure the real-time, stable and effective transmission of the information. Via experimental tests, the system can obtain various monitoring data from external bluetooth and external NRF radio frequency devices in real time. The data can also be steadily obtained from the computer and other external equipments in real time. The system has extensibility and is allow to be extended to support more wireless communication protocols by changing or adding different communication protocol modules.
