Bluetooth-based double-group counterweight block motion data acquisition system

The utility model provides a Bluetooth-based double-group counterweight block motion data acquisition system, which is characterized by comprising a display subsystem, a motion data acquisition subsystem A and a motion data acquisition subsystem B, the motion data acquisition subsystem A comprises a digital label unit A, an identification unit A, an acquisition unit A, a Bluetooth transmission unit A and a power supply A; the motion data acquisition subsystem B comprises a digital label unit B, an identification unit B, an acquisition unit B, a Bluetooth transmission unit B and a power supplyB; and the motion data acquisition subsystem A is respectively connected with the motion data acquisition subsystem B and the display subsystem through Bluetooth. A Bluetooth working mode of a Bluetooth transmission unit A of the motion data acquisition subsystem A is a one-master multi-slave mode; a Bluetooth working mode of a Bluetooth transmission unit B of the motion data acquisition subsystemB is a slave mode; and th
