Intelligent manufacturing PLC experimental device

 

This device is developed according to the "Elementary Program Control System Designer" tr--ning and the national vocational standard assessment outline formulated in accordance with the Ministry of Human Resources and Social Security. of. Suitable for vocational colleges, vocational tr--ning schools, vocational education centers, appr--sal stations/appr--sal stations, tr--ning and skill appr--sal of the fourth, third, and secondary levels of the designer of the programmatic program control system.

 

2. R & D background

 

1. This device is based on the tr--ning of the "Summable Program Control System Designers" tr--ning and outline of the national vocational standard assessment formulated by the Ministry of Human Resources and Social Security. And developed.

 

2. The requirements for rapid development of processors are continuously improved. Teaching needs to be continuously upgraded with the current equipment, and teaching needs to start from basic learning. At the same time, it is necessary to meet the need for laboratory construction to cause waste of funds and laboratory space.

 

3. One product requires multiple processing processes, which leads to the complexity of the industrial site equipment. A host cannot complete all the tasks, and multiple sites need to be done with each other.

 

4. The assessment of different levels requires different equipment and cannot be organized organically. After some tr--ning, some tr--ning cannot take consideration to check the degree of acceptance of students.

 

Third, product characteristics

 

1. The concept of tr--ning and construction is one -time construction. This equipment uses a general -purpose wide exhibition port. All host's I/O ports can be drawn through the expansion port. Tr--ning; there are two demolished mesh boards that can evaluate students at different levels.

 

2. Use module combined structures, including switching, analog quantity, frequency conversion speed regulation, touch screen, communication module, etc., supporting MCGS industrial control configuration monitoring software to achieve simulation and information tr--ning teaching.

 

3. Project tr--ning module: Use the current typical programmable controller and bus technology to complete the control objects of typical cases in industrial production, logic, simulation, process, and movement in the physical model.

 

4. Simulation tr--ning teaching: In real time, the PLC operating status is displayed in real -time in the virtual environment, and the field control of the simulation industry can perform programming tr--ning, programming testing and other functions.

1. Product introduction

 

In order to adapt to the development of various fields as soon as possible, to cultivate technical workers, technicians, engineers, engineers, and various fronts that master the basic knowledge of hydraulic transmission and actual operating skills. Our company refers to advanced foreign technologies based on the content requirements of "Hydraulic Transmission", "Principles of Hydraulic Pressure", "Mechanical Basics", and the characteristics of domestic hydraulic components. The high -precision processing process is adopted to overcome a series of practical difficulties that transparent organic plastic are thermoplasticity, easy to deform, and poor mechanical strength, while hydraulic component surface smoothness, high structural accuracy requirements, and finally developed a successful transparent hydraulic transmission demonstration system.

Various mechanical requirements for hydraulic transmission are diverse. Generally, most of the basic function circuits such as control circuit, pressure control circuit, speed control loop, and sequential control circuit. The experimental screen of the experimental table is made of 1.0mm cold -rolled steel plate. Each hydraulic element uses a transition bottom plate. The overall appearance is beautiful and generous, the structure is solid and durable, and the operation is convenient. This demonstration system uses the experimental demonstration of the eighteen basic control circuits of the above four basic functions (60 extension experiments), so that students can familiarize the structure, performance and use of more than 20 common hydraulic elements, and master a dozen dozen. The working process and principles of the basic circuit to improve the ability to deal with students' fault treatment and solve problems, which is inspired in the experimental demonstration and triggers interest. Using it can experiment with other oil circuits within the tolerance provided by this product ( As shown in the figure, graduation design).

This product refers to the characteristics of domestic hydraulic components, which is more suitable for domestic teaching requirements. The system adopts transparent hydraulic components, combined card slot structures, active oil circuit joints, general electrical lines, and uses the admission tool material to refer to the experimental guidance book. Students understand the principles, structure and working process inside the oil circuit and hydraulic element, which is an ideal equipment for hydraulic transmission teaching.
