For large power consumption, short using time and detecting special conditions could not real-time feedback problems existing in current wireless dynamometer, a wireless dynamometer test system was designed to solve the above problems.Through designing the hardware and software for the system, low power consumption, long service life of battery and timely feedback of detecting special conditions and other functions were realized. The oil field measured data show that the performance of the system is stable and reliable, and it can be used for long-term monitoring of oil well production status.
