Design of High Frame Frequency Data Communication System on Theodolite

Abstract:

The data communication system is the internal data exchange platform of theodolite, which completes data exchange among multiple subsystems. According to requirement of proving range to target attitude measurement, the rate of real time target image storage is quicker and quicker, as the synchronous measurement information deliverer, the communication frame frequency of data communication is also increasing. Adopting time pre-processing method resolves the problem that B code terminal cannot provide high frame frequency time information, The utilization of ARM processor built in watchdog counter function and configuration of external interruption signal can realize the precise time sequence control, and realize the synchronous transmission of measured data in case of high frame frequency, and the software realization method is provided.
