  "abstract": "A cable length measurement device, configured to: be connected a winding wheel and measure an extension or retraction length of a cable on the winding wheel, which includes a fixed shell, a rotating shell and a control panel. The rotating shell is rotatably connected to the fixed shell. The rotating shell is configured to be connected to the winding wheel and rotate around a rotation axis with the winding wheel. One of the fixed shell and the rotating shell is provided with a signal transmitter. The other one of the fixed shell and the rotating shell is connected to the control panel. The control panel is provided with a signal receiver. When the signal transmitter passes through the signal receiver, the signal receiver generates a counting signal, and the control panel receives the counting signal to calculate the extension or retraction length of the cable on the winding wheel.",
