The invention discloses a tower crane detection system for a fabricated building, and effectively solves the problem that in the prior art, a sensor arranged for a lifting motor of a tower crane cannot detect the aging phenomenon of the lifting motor, so that the normal hoisting work of the tower crane is influenced. The signal detection circuit detects a vibration signal and a sound signal when the lifting motor works at a low speed by using a vibration sensor U1 and a microphone M1 respectively, calculates the vibration signal and the sound signal respectively, obtains a ratio signal and an abnormal sound signal, and transmits the ratio signal and the abnormal sound signal to the signal processing circuit; and the signal processing circuit obtains an alarm signal by utilizing the ratio signal and the abnormal sound signal, obtains an aging signal of the hoisting motor winding by utilizing the alarm signal and the crack signal, and transmits the alarm signal and the aging signal to a control center through the signal transmission module, so that the normal hoisting work of the tower crane is ensured.
