Research Of Wireless Data Transmission System Based On PTR4000

Wire communication system cannot meet the need of development andapplication of communication technology due to its limitation of on wiring and netting,and the shortage of high building cost. Wireless communication technology has beenpaid more and more attention in many provinces, and was developed rapidly. Circuitand software design of wireless data transmission system based on PTR4000 wasresearched in this paper.The background and the present research status of wireless data transmissionsystem based on PTR4000 is introduced as well as the content of this paper at first. Afterthat, the model of wireless data transmission system is studied. The construct andperformance of this system, and the main factors that affect wireless transmission havebeen studied. The critical techniques such as digital modulate mode, error control, andcommunication protocols are also discussed.The basic architecture of data acquisition system is introduced. The frame ofdistributed data acquisition system based on wireless transmission is presented. The partof data acquisition system that is about wireless data transmission is studied. The projectdesign and realization of wireless data transmission system based on PTR4000 has beenelaborated. The general project design is presented, and the constitution of the circuit iselaborated accordingly. The wireless data transceiver module named PTR4000, whichtakes nRF2401 as kernel chip, the single chip microprocessor named AT89LV51, andtheir circuit connection is introduced. At the same time, the software design is elaboratedincluding the main program and several primary subprograms. The distance andreliability in open terrain, and barrier terrain and on rotary condition of wireless datatransmission system is tested and analyzed.The research of wireless data transmission system is summarized, and aspects to beimproved in the future are listed at last.
