Embodiment 1

[0021] Embodiment 1: Design and implementation of the three-position round-trip electric control system for the trolley

[0022] Task description: Use the relay contactor control method to realize the delayed round-trip control of the trolley position. That is, the car starts from point A, stays at point B for 10 seconds, then continues to move to point C, and stays for another 10 seconds; then reverses back to point B, stays for 10 seconds, and then continues to return to point A and stops. For the task schematic diagram and the car path diagram, see image 3 , Figure 4 .

Embodiment 2

[0023] Embodiment 2: Design and implementation of electrical control system for four-station assembly line

[0024] Task description: Use the relay contactor control method to realize the electrical control of the four-station assembly line of the workpiece. That is, after the workpiece arrives at the feeding port, it is transferred to station 1 through conveyor belt A to stop; after processing at station 1, it is transferred to station 3 through bridge plate A; after processing at station 3, it is transferred to station 1 through conveyor belt B. Station 4 stops; after the processing of station 4 is completed, it is transferred to station 2 through bridge plate B; after station 2 is completed, it is transferred to the discharge port through conveyor belt A to end. For task diagram see Figure 5 .

Abstract

The invention discloses a training system for logic control. The training system for logic control comprises a logic control practical training carrier and a control device. The logic control practical training carrier is composed of a support, a speed reducing motor, a conveying belt, a position detecting switch, a standard linear air cylinder, a bridge plate, a wiring terminal and the like. A mesh plate is used in the control device, and the control device is provided with discrete components such as an air switch, a contactor, a thermal relay, an intermediate relay, a time relay, a 24V switching power supply, a button, an indicating lamp and a wiring terminal. The training system for logic control can be combined to achieve tens of practical training projects in electrical control, the equipment structure is simple, operation is easy, covering range is wide, the training system is vivid and visual and is beneficial to arousing the learning interests of students, the practical training effect is guaranteed, the requirements for all skill training of curriculum requirements are met, and good popularization value is achieved.

Description

technical field [0001] The invention relates to a training system for scientific research and teaching, in particular to a training system for improving the logic control skills of students majoring in electrical and automation. Background technique [0002] In modern vocational education, in order to improve students' hands-on ability and adapt to the requirements of future work as soon as possible, some targeted general-purpose training devices are usually used to conduct skill training and assessment for students, so that students can practice in a series of activities close to the actual working environment of the factory. During the training process, master the professional skills required by this major, and provide excellent skilled talents for enterprises. [0003] The current general-purpose training equipment used for logic control has single training items and content, and insufficient expandability. It is difficult to adapt to the development requirements of profe...
