Multi Channel Wireless Data Transceiver Design And Research

In the wireless sensor networks based on the environmental monitoring, data collection is the core of the monitor system. Wireless sensor networks (WSN) has been more widely applied as the base of the Internet of Things. The monitor aims should be arrived by analysis the datas that the collected through WSN. With the improvement of real-time needs, face the challenges of the reliability of datas and real-time transmit, the traditional data collection methods should not meet people’s requirements. Therefore, the datas collection methods have changed from the artificial to network remote collection. Transmit channels has also transformed from single channel to the multi-channels. Transmit network has developed from a single structure to a variety of heterogeneous networks. It is not difficult to see that the great significance of multi-channels real-time data transmit system with the heterogeneous.This paper proposed the specific schemes of the real-time monitor datas transport based on the wireless sensor network. The design of multi-channels wireless data transceiver has been completed by multi-channels and heterogeneous network to closely integrate. By the combination of ethernet and GPRS to realize a double transmission channels system, and finish the data real-time forward. In the process of project implementation, carried out a detailed study on the architecture and work principle of the entire transmission system, analysised the data transfer protocols, combined the system model and protocol conversion thinkings to achieve a multi-channels transmit mechanism. The modular approach was adopted to design the hardware and software system, and the modules with independence functionp are together to complete the transfer tasks through cooperation. In the design of the system software, built the system base on the embeded linux, completed the cut of the Linux system kernel, some drivers’development, and the kernel transplantation. The design of multi-channels data transceiver of the software base on ARM, we applied the Qt4and combined with the modular methods to realize the function of multi-channels transmit. In the end, the multi-channels wireless transceiver system has been tested and met the basic needs.In the project research, depend on the model of the multi-channels wireless data transceiver, apply the transport protocols and embedded technologies to build a new transfer mode. We realized the multi-channels transmit base on many differents protocols on one hardware platform. It is possible to achieve real-time data acquisition, transmit and network shared. The high performance ARM processor has been used in real-time datas acquisition system which realized the power of the low consumption and the resources of the high efficient use.
