Abstract
At present, the data transmission of total station is transmitted by wired mode, which requires the laying of transmission line hardware and has a high cost. In this paper, the total station wireless data transmission system is designed by using TMS320F28335 DSP and nRF905 wireless transceiver module. The system consists of wireless module sending data node and receiving node, displaying the data collected by the total station on the upper computer and applying it. The hardware design of the system includes the interface circuit between total station and DSP, the hardware circuit between wireless module and DSP, and the serial communication between DSP and host computer, and the software part includes nRF905 software, DSP control program software, and CSI serial communication software. The experimental results of wireless transmission waveform and PC serial port debugging show that the design can achieve wireless transmission of total station data, and the results are accurate.
