Bluetooth Technology Applied in Theodolite

Theodolite data are recorded by person, there is human error and post-processing workload. Transmitted by USB data cable realized digital transmission and recording, but person activities are yoked by the cable, field operation is inconvenient and inflexible enough. Often plugging USB data cable, poor contact and the equipment damaged are easy caused, etc. Single-chip Microcomputer and Bluetooth technology are applied in wireless transmission and control of theodolite data, it is realized that mapping data are wirelessly transmitted and storaged to the PDA. The experiment indicated that the communication distance is more than 500 meters, which the error rate is 0%, and that it is also 0% to avoid obstacle transmission error rate.
