[0016] The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0017] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0018] In this embodiment, a dual-controller motion control training platform includes a platform body, on which an electrical control system is arranged, characterized in that the electrical control system includes a motion controller based on upper computer programming control and a PLC controller based on special programming software programming control; The platform is also provided with a switching module, and the switching module can switch between a motion controller based on the programming control of a host computer and a PLC controller based on the programming control of a dedicated programming software.

[0019] The purpose of this design is to set up a dual controller consisting of a motion controller based on host computer programming control and a PLC controller based on special programming software programming control, so that it can be used as a training platform for core professional courses such as electrical and PLC control technology, motion control technology, etc. in the electrical major.

[0020] In this embodiment, Figure 1 As shown in the figure, the training platform is mainly composed of a variety of training modules distributed on the table and an electrical control system composed of several electrical components installed under the table. The electrical components on the training modules are connected to the electrical control system through cables. The training modules are mainly composed of sensor modules, assembly line modules, three-axis manipulator modules and motor characteristic modules. The electrical control system of the training platform uses a motion controller based on host computer programming control and a PLC controller based on special programming software programming control as the control core. Only one of the dual controllers can be selected at the same time.

[0021] The designated controller is selected to carry out relevant training through one-touch switching of the first switching knob; the training platform adopts a common driver, and the motors of the three-axis robot module and the motor characteristic module are switched and controlled through one-touch switching of the second switching knob.

[0022] The training platform can be used as a training platform for core professional courses such as electrical and PLC control technology, motion control technology, etc. in the electrical major.

[0023] like Figure 2 As shown, the training platform provided in this embodiment can realize one-click switching of dual controllers and one-click switching of actuators by sharing drivers between training modules.

[0024] The one-button switching operation mode is: switch the controller through the first switch knob, and switch the training module (motor characteristic module / three-axis manipulator module) through the second switch knob.

[0025] Its operation is that the first switching knob is used to connect / disconnect several relay coils for switching of the first relay group, and the second switching knob is used to connect / disconnect several relay coils for switching of the second relay group.

[0026] like Figure 3As shown, in the training platform provided by this embodiment, various general external IO elements such as sensors, solenoid valves, buttons, indicator lights, etc. involved in each training module are connected to the common end of the normally open and normally closed contacts of several relays in the first relay group. The coils of these relays can be quickly connected / disconnected with one click through the first switching knob, and then the normally open contacts of these relays are connected or the normally closed contacts are connected, thereby switching the external IO elements to connect to the PLC module or the motion controller module, and completing fast and reliable switching. The training platform is extended to multiple courses by switching the controller, which improves the utilization rate of the training platform.

[0027] At the same time, in this embodiment, if Figure 4 As shown, multiple control signals involved in each driver, such as enable, reset, fault, ready, pulse, direction, etc., are connected to the common end of the normally open and normally closed contacts of several relays in the first relay group. The coils of these relays can be quickly connected / disconnected by one button through the first switching knob, and then the normally open contacts or normally closed contacts of these relays are connected, thereby switching the control signal of the driver to connect to the PLC module or the motion controller module, completing the fast and reliable switching of the control end.

[0028] At the same time, the output power lines, encoder lines, and brake lines of the drivers such as servo / stepper / frequency converter are connected to the common terminals of the normally open and normally closed contacts of several relays in the second relay group. The coils of these relays can be quickly connected / disconnected with one click through the second switching knob, and then the normally open contacts or normally closed contacts of these relays can be connected, thereby switching and selecting multiple motors involved in different training modules connected to the driver, and completing fast and reliable switching of the actuator end. The training module is expanded by switching the motors of the training module with a shared driver, which reduces the overall cost of the training platform.

[0029] In this embodiment, a dual-controller motion control training platform fast switching method is also provided, which is implemented based on a dual-controller motion control training platform and includes the following steps: Start dual-controller motion control training platform; Rotating the first switching module to switch functions between the motion controller based on the programming control of the host computer and the PLC controller based on the programming control of the dedicated programming software; The second switching module is rotated to switch between the motor used to control the three-axis manipulator module and the motor used to control the motor characteristic module.

[0030] The purpose of this design is that the controller and actuators such as servo / stepper / variable frequency motor parts can achieve one-click switching operation with a short switching time. By sharing drivers such as servo / stepper / variable frequency drivers among multi-module application units, the switching motor solution reduces the overall cost. The dual controllers can adapt to multiple training objects or courses, thereby improving the utilization rate of the training platform.

[0031] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
