Method and system for controlling and tracking speed of multi-freedom degree track trolley

Abstract

The invention belongs to the field of the motorized rides and provides a system and a method for controlling and tracking the speed of a multi-freedom degree track trolley, wherein the method comprises the following steps of: generating technical parameters which can be recognized by a PLC (Programmable Logic Controller) from a motion-trajectory technical parameter document and keeping the generated technical parameters in a PLC memory unit; compiling the PLC algorithm programs of a traveled distance, a rotation angle and an inclination angle of the trolley during motion through a CPU (Central Programming Unit) within the PLC; after the trolley is started, detecting a track position signal by the PLC according to a sensor, executing different algorithm programs, and calculating the difference value between the actual motion parameter and the target parameter of the trolley during motion in real time according to the predetermined motion trajectory target parameters stored in the memory unit; and proportionally outputting voltage values to a trolley servo output control unit so as to control the speed of the motor of the trolley to realize quick trolley tracking, thereby obtaining an ideal motion trajectory.

Description

technical field [0001] The invention belongs to the field of motorized amusement facilities, and in particular relates to a speed control and tracking system and method for a multi-degree-of-freedom track trolley. Background technique [0002] In the playground, when tourists watch movies or perform stunts in cars, tourists can do various simulation actions according to the movie scenes or stunt plots, and the accurate real-time performance of various actions will make tourists physically and mentally synchronized with visual experience. , so that it can achieve the feeling of being in the scene. [0003] The track trolley uses the track to set the driving route of the trolley, so that the trolley can travel with multiple degrees of freedom on the track, and the operation of the trolley is controlled by a PLC programmable logic controller. PLC is an electronic system for digital operation. The memory of the programmable program is used to store operation commands such as lo...

AI Technical Summary

Problems solved by technology

At present, the track trolley control system is generally connected with the PLC programmable logic controller through the host computer (background host). The system control needs to call the control software of the host computer in the background through the PLC, and the PLC executes the control commands issued by the host computer to control the operation of the trolley, which makes the communication time delay longer, so it is impossible to truly realize the fast tracking control of the trolley
