DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In one embodiment, a new type of PLC training platform is provided, such as Figure 1-8 As shown, the new PLC training platform includes a test platform 1, which includes a square box on the outside. A PLC 2 and an industrial control device 3 are provided in the test platform 1. The industrial control device 3 is provided with a display screen. In this embodiment, the industrial control device 3 is an industrial control all-in-one machine. In other embodiments, the industrial control device can also use an industrial touch screen, a desktop computer, a tablet computer or an all-in-one computer.

[0027] An operation panel 21 is provided on the front side of the experimental table 2. The PLC 2 and the industrial control device 3 are embedded in the operation panel 21. The display screen of the industrial control device 3 is located on the operation panel 21, and the progress of the experiment can be observed from above. The operation panel 21 is provided with a PLC input port group 22, a PLC output port group 23, an industrial control device input port group 24, and an industrial control device output port group 25. Each port in the PLC input port group 22 is electrically connected to the input terminal of the PLC 2, each port in the PLC output port group 23 is electrically connected to the output terminal of the PLC 2, each port in the industrial control device input port group 24 is electrically connected to the input terminal of the industrial control device 3, and each port in the industrial control device output port group 25 is electrically connected to the output terminal of the industrial control device 3. The PLC input port group 22 includes 24 signal input ports, numbered I0.0 to I0.7, I1.0 to I1.7, I2.0 to I2.7, and I3.0 to I3.0. .7, and also includes a common input port 1M; PLC output port group 23 includes 16 signal output ports, numbered Q0.0 to Q0.7 and Q1.0 to Q1.7, and also includes four common output ports 1L to 4L; industrial control equipment input port group 24 includes 32 signal input ports, numbered DI0 to DI31, and also includes a common input port COM; industrial control equipment output port group 25 includes 32 signal output ports, numbered DO0 to DO31, and also includes a common output port COM. Each port in PLC output port group 23 and PLC input port group 22 is used to electrically connect to a port of industrial control equipment input port group 24 and industrial control equipment output port group 25 via a communication line, so that PLC2 and industrial control equipment 3 can communicate with each other and realize the experimental function of PLC.

[0028] This new type of PLC experimental platform is used to complete PLC programming and other related teaching tasks. Its working principle is as follows: students perform PLC programming through a PC (computer) or other programming device, and then download the program to PLC2 through a communication line. According to the experimental requirements corresponding to the programming, the wiring port on one side of PLC2 is connected to the wiring port on the side of the industrial control equipment 3 through the experimental wire. The PLC2 and the industrial control equipment 3 are connected through the experimental wire. The corresponding experimental model is selected in the human-machine interface (display screen) of the industrial control equipment 3 to conduct the experiment. Since the input port of PLC2 is connected to the output port of the industrial control equipment 3, and the output port of PLC2 is connected to the input port of the industrial control equipment 3, when PLC2 outputs a signal, the corresponding input port on the side of the industrial control equipment 3 detects the connected signal, and the corresponding information is displayed on the screen of the industrial control equipment 3. At the same time, when the industrial control equipment 3 outputs a signal, the corresponding input port of PLC2 can detect the connected signal, thereby realizing signal feedback. In this way, by editing different experimental screens in the industrial control device 3, different control processes can be realized, thereby realizing the experimental functions of the PLC device, and more functions such as assessment can be achieved by designing different experiments.

[0029] The new PLC experimental platform has the following characteristics: the device can replace the traditional PLC training machine. Since the PLC simulation experiment screen is realized through the industrial control equipment, the trouble of the traditional training equipment requiring a hanging box for each experiment is eliminated. The screen switching within the industrial control equipment 3 realizes the conversion of different experiments. When a series of experiments are completed, there is no need to perform multiple hanging box operations. At the same time, compared with the fixed single hanging box screen of the traditional hanging box, the new PLC experimental platform can realize vivid functions such as 3D animation, which is conducive to students to better learn and understand PLC. In addition, the new PLC experimental platform is equipped with multiple groups of input and output ports and has the function of wiring between ports, that is, it has the hands-on and training functions of traditional training equipment, which is different from the general PLC simulation or twin functions. Therefore, the new PLC experimental platform simplifies the traditional equipment and increases the operability. Users can design and expand more experiments without adding any hardware equipment.

[0030] The following are several experiments to detail the specific training methods of the new PLC test bench:

[0031] like Figure 9 As shown, Figure 9This is the interface diagram for an elevator control experiment using this new PLC training platform. This interface is displayed on the screen of industrial control device 3. During the experiment, students program the PLC using a PC (computer) or other programming device according to the experimental requirements for elevator control. They download the software for controlling the elevator to PLC2 and then, using experimental wires, connect the wiring ports on one side of PLC2 to the wiring ports on the other side of industrial control device 3 in a one-to-one correspondence according to the experimental requirements for elevator control. By operating the corresponding buttons on the interface displayed on industrial control device 3, the elevator can achieve the corresponding function. The display screen of industrial control device 3 can be either a touch screen or a non-touch screen. A non-touch screen requires a mouse or keyboard for operation.

[0032] like Figure 10 As shown, Figure 10 This is the interface diagram for using the new PLC training platform to control traffic lights. The interface is displayed on the screen of the industrial control equipment 3. When conducting the experiment, the trainees program the PLC through a PC (computer) or other programming device according to the experimental requirements of the traffic light control, and download the software for controlling the elevator to PLC2. Then, according to the experimental requirements of the traffic light control, the wiring ports on one side of PLC2 are connected to the wiring ports on the side of the industrial control equipment 3 one by one through the experimental wires. By operating the corresponding buttons on the interface displayed on the industrial control equipment 3, the traffic light can realize the corresponding function.

[0033] like Figure 11 As shown, Figure 11 This is an interface diagram of the offshore tower light lighting control using an embodiment of the new PLC training platform. The interface is displayed on the screen of the industrial control equipment 3. During the experiment, the trainees perform PLC programming through a PC (computer) or other programming device in accordance with the experimental requirements of the offshore tower light lighting control, write the software for controlling the elevator lifting and download it to PLC2, and then connect the wiring port on one side of PLC2 to the wiring port on the side of the industrial control equipment 3 one by one through the experimental wires in accordance with the experimental requirements of the offshore tower light lighting control. By operating the corresponding buttons on the interface displayed on the industrial control equipment 3, the offshore tower light can realize the corresponding function.

[0034] Furthermore, in another embodiment, Figure 1-8As shown, the new PLC training platform is also provided with a level indication port group 26, a level switch port group 27 and a signal power port 28 on the operation panel 21, wherein the level indication port group 26 includes a common level indication input port COM and 12 level indication output ports, and the 12 level indication output ports are numbered Q0.0~Q0.7 and Q1.0~Q1.3 respectively, and each level indication output port is electrically connected to the common level indication input port COM through a level indicator light; the level switch port group 27 includes a common level switch input port COM and 16 level switch output ports, and the 16 level switch output ports are numbered I0.0~Q0.7 and I1.0~Q1.7 respectively, and each level switch output port is electrically connected to the common level switch input port through a level switch. The signal power port 28 has two sets of 24V DC power interfaces. Each set of 24V DC power interfaces includes a positive interface and a negative interface. An indicator light is provided between the positive interface and the negative interface. When the indicator light is on, it means that the power supply is energized. The signal power port 28 is powered by a power module set in the new PLC training platform.

[0035] The level indication port group 26 and the level switch port group 27 are used as follows: for example, the common level switch input port COM is electrically connected to the positive pole of a group of 24V DC power supply interfaces in the signal power port 28 through an experimental wire, and then a level switch output port I0.0 is electrically connected to an input port of PLC2 through an experimental wire. When the level switch output port I0.0 is pressed, a high-level electrical signal can be input to an input port of PLC2 to realize the control function.

[0036] Furthermore, in another embodiment, Figure 1-8 As shown, the new PLC training platform is further provided with a signal power switch 281 electrically connected to the signal power port 28 and a PLC power switch 29 for controlling the PLC on the operation panel 21, which is used to control the corresponding power switch.

[0037] Furthermore, in another embodiment, Figure 1-8 As shown, the new PLC training platform also includes a computer host 6 and a display screen 4 for programming. Programs can be compiled through the computer host 6 and then downloaded to the PLC 2.

[0038] Furthermore, in another embodiment, Figure 1-8 As shown, the new PLC training table also includes a table 5, on which the experimental table 1, the computer host 6 and the display screen 4 are arranged. A support plate for placing the computer host 6 is provided at the bottom of the table 5, and universal wheels are provided at the four corners of the table 5.
