[0034] The present invention will be further described in detail in conjunction with the following specific embodiments and accompanying drawings. The process, conditions, experimental methods, etc. for implementing the present invention, except for the content specifically mentioned below, are common knowledge and common knowledge in this field, and the present invention has no special limitation content.

[0035] Figure 1 to Figure 4 Among them, 1-control unit, 2-motion controller, 3-motor.

[0036] figure 2 Shown is the structure diagram of the CT bed motion control system based on time series trajectory points. The control unit 1 is time-synchronized with the motion controller 2 . The motion controller 2 can control the working state of the motor 3 . The motion controller 2 has at least an internal buffer area with a length of 2 data points for storing received track point data (dummy data), for storing corresponding track point data.

Abstract

The invention discloses a CT (Computed Tomography) bed motion control method based on time sequence track points. The method comprises steps of receiving the first section of track point data; receiving a starting motion instruction and controlling a motor to enter the motion state and execute the first section of track point data; feeding state word data with motor starting time information back; receiving the second section of track point data based on the state word data; receiving track running data; and controlling the motor to carry out corresponding track motion. According to the method, the influences of network delay on motor running precision are eliminated and the control precision is improved. The invention also discloses a CT (Computed Tomography) bed motion control system based on time sequence track points.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a CT bed motion control method and system based on time series trajectory points. Background technique [0002] At present, in the computerized tomography imaging system (CT, Computed Tomography), the control of the CT bed mainly uses a closed-loop driver to directly control the motor. In order to make the motor run at a precise time point, a high-precision clock is required. and real-time systems to generate motion control commands at precise points in time. If the CT bed is to start running at a certain moment, and run according to the planned position and speed, the existing method is to send a motion command at the starting moment. In a distributed system, network delays occur during data transmission. The existing method needs to consider the network delay, which will have a negative impact on the accuracy of the start command sent by the controller and the...
