Obstacle point detection method and system and test equipment

The invention discloses an obstacle point detection method and system and test equipment, and relates to the field of communication technologies. The obstacle point detection method comprises the steps that the test equipment acquires a calibration value corresponding to the test equipment; the test equipment measures a signal level value of a feeder joint; the test equipment acquires a calibratedsignal level value of the feeder joint according to the measured signal level value and the calibration value; and the test equipment judges whether the feeder joint has an obstacle or not accordingto a comparison result of the calibrated signal level value of the feeder joint and a standard signal level value. When obstacle point detection is performed, a calibration value corresponding to thetest equipment is firstly acquired, then calibration is performed on a measured signal level value by adopting the calibration value, and whether the feeder joint has a fault or not is judged according to the calibrated result,
