The invention provides a stroke limiting control system and method based on speed control, and belongs to the field of tower crane control. The system and the method are applied to a working motion mechanism of the tower crane. The method comprises the steps that under the circumstance that the motion mechanism meets a first speed limiting condition, speed limiting operation is executed on the motion mechanism according to the real-time stroke of the motion mechanism, according to the speed limiting operation, the motion mechanism is controlled to operate at different operation speeds in a speed reduction manner during different speed limiting sections from the first speed limiting point, until the operation stop point is reached, and the speed limiting sections at least comprise linear speed reduction sections. Limiting control of the tower crane is divided into the multiple speed reduction sections comprising linear speed reduction sections, while stable speed reduction is ensured, system operation efficiency is further improved, and impact on the system is reduced.
