[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] like Figure 1As shown, a multifunctional control box training device comprises a multifunctional control box, wherein the multifunctional control box comprises a 16-bit lever 10 arranged in sequence, an experimental module LED light board 20 for realizing input and output indicator lights of different experimental modules, a 16-way LED indicator board 30 for displaying the 16-bit lever 10, a seven-segment code display board 40, an analog quantity unit 50 for realizing the acquisition and display of PLC analog quantity input and output signals, and a card reading area 60 with a reading function;

[0024] The training device also includes cards with different PLC programs. By cooperating with the control experiment box, different cards realize different functions. By placing the cards on the card reading area 60, different PLC programs can be read.

[0025] like Figure 2 As shown, the card reading area 60 is also connected to the PLC unit 70, and the 16-bit lever 10 is also connected to the PLC unit 70. After reading the PLC program on the card, the 16-bit lever 10 performs binary encoding and outputs it to the PLC unit 70. According to the PLC program of the card, different encodings represent different actions. In addition, the 16-bit lever 10 is also connected to the 16-way LED indicator board 30, and the 16-way LED indicator board 30 can display the output of the 16-bit lever 10;

[0026] Each switch of the 16-bit lever 1 corresponds to an input point of the PLC. When the switch is turned to the left, the point outputs a signal "1", which is a hold switch; when the switch is turned to the right, the point also outputs a signal "1", which is a momentary switch.

[0027] Taking automobile control as an example, the working principle of the control experiment box is explained. Figure 2-3 As shown, by placing the corresponding car program card on the card reading area 60, the card reading area 60 reads the PLC program and inputs it into the PLC unit 70. The PLC unit 70 is also connected to the execution unit 80. In this embodiment, the execution unit 80 is a vehicle, and the binary code is output through the 16-bit lever 10. For example, the function corresponding to the lever of the first path is the start of the car. After the lever is moved, the binary code input to the PLC unit 70 is I0.0. The PLC unit 70 reads the code and then transmits it to the execution unit 80 (car) to execute the start command, and the rest are as follows Figure 3 As shown, I0.1 represents braking; I0.2 represents reversing; I0.3 represents turning on the car headlights, etc.

[0028] like Figure 4 As shown, different cards correspond to different PLC control programs. The control experiment box can also be used to control traffic lights. For example, the car control method is the same. Take I0.2 as an example. Figure 4As shown, after the PLC unit 70 inputs the I0.2 signal, the PLC unit 70 outputs Q0.2. At this time, the green light for the north-south direction shown in the figure is on, thereby achieving the purpose of north-south straight driving. The above operations can enable the execution unit 80 to perform different operations by moving different levers differently.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
