The invention discloses a tower crane walking mechanism control system and method.The tower crane walking mechanism control system comprises a tower crane precise stop algorithm controller, and a reference value of a current tower crane stop error is obtained according to an error between an actual stop position and an expected stop position of a last tower crane and a predicted value of the current tower crane stop error; determining a brake control strategy according to the reference value; according to the current speed of the tower crane and the braking distance of the tower crane when the tower crane is braked, the operation acceleration is calculated in combination with the braking control strategy; the braking system performs braking response according to the calculated operation acceleration; the speed sensor is used for measuring the current speed of the tower crane when the tower crane is braked; the distance sensor is used for measuring the braking distance of the tower crane when braking is adopted and measuring the actual error when the tower crane stops; and the tower crane stop error data acquisition system is used for acquiring the stop error data of the tower crane and feeding back the data to the tower crane precise stop algorithm controller for subsequently predicting the stop error of the tower crane.
