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.
