Abstract

The invention discloses an intelligent deceleration system and method. The method includes the following steps that: the real-time position data and speed data of a walking platform are obtained through detection, and a dynamic deceleration distance is obtained through calculation; the validity of the dynamic deceleration distance is judged, and if the dynamic deceleration distance is invalid, thewalking platform is controlled to perform speed-limited operation, and the walking platform is finally limited and stopped through a mechanical rocker arm; if the dynamic deceleration distance is valid, a dynamic deceleration point is calculated; when the walking platform reaches the dynamic deceleration point, deceleration detection is performed on the walking platform; if it is detected that the deceleration of the walking platform is qualified, a two-stage deceleration scheme is adopted, so that the walking platform decelerates and stops at a preset stopping position; and if it is detectedthat the deceleration of the walking platform is unqualified, the walking platform is controlled to perform speed-limited operation, and the walking platform is finally limited and stopped through the mechanical rocker arm. According to the intelligent deceleration system and method of the invention, the dynamic deceleration distance is calculated, so that the dynamic deceleration point can be obtained, and therefore, the operating efficiency of the system can be improved; and the two-stage deceleration scheme is adopted as a position control strategy, and therefore, millimeter-level design technical requirements can be satisfied.

Description

technical field [0001] The invention relates to the field of parking control, in particular to an intelligent deceleration system and method applied to a walking platform. Background technique [0002] The main task of the walking platform is to transport super-large loads from the technical workshop to the relevant work stations. Stepless speed regulation can be realized throughout the walking process, and the stop point of the relevant work stations needs to achieve millimeter-level position control accuracy. In the prior art, the mechanical stop limit is used to control the parking point within 1 meter from the end point, and then the walking platform is micro-operated by manual control to realize the alignment function. Since there is no intervention of position control technology in the whole process, the fixed deceleration point deceleration method of magnet limit induction is adopted. There are following three deficiencies in the above scheme: [0003] 1. The speed ...
