AI Technical Summary

Problems solved by technology

This technology enables students to learn and understand the principle and use of refrigerators perceptually, intuitively and clearly, but there are still problems that all components are fixed installation, large in size, relatively simple in experimental content, short in experimental process, large in size and occupying a large area , lack of comprehensiveness and other shortcomings

[0005] 2.1.3 The utility model patent "Comprehensive Experimental Platform for Basic Experiments of Process Equipment" (Patent No. ZL200720148945.3) proposes an experimental platform that combines equipment experiments, process experiments and control experiments, allowing students to combine process equipment, The process and process control are linked together. Although the comprehensiveness is increased, the volume is large, the equipment structure is fixed, and the designability, variability, installability, and visibility are still relatively poor.

[0006] 2.1.4 The utility model patent "Sensor Comprehensive Experimental Platform" (Patent No. ZL200720112610.6) proposes a sensor technology comprehensive experimental platform including the screen body, the detected source, the sensor signal conditioning module and the experimental table. Good variability, designability, and assembleability, but it is still specially equipped with screens, consoles, etc., which are bulky and have low interdisciplinary degrees

[0007] 2.1.5 The article "Development of FANUC CNC system comprehensive experimental device platform", ("China Modern Educational Equipment", Cao Jinjiang, Yu Hanqi, Li Hongsheng), proposed "NBF-1 FANUC CNC (lathe) system comprehensive experimental device", Various mechanical and electrical structural components are fixedly installed on the operating table and mechanical execution test bench in a modular manner, and a transparent cover is used to enhance the comprehensiveness and observability of the platform, but its various modular structural components are still It is a fixed installation, it is inconvenient to disassemble and assemble, the volume is large, the versatility of the module is not strong, and the utilization rate is low

[0008] 2.1.6 The article "Construction of Electronic Information Technology Comprehensive Experimental Platform" ("Experimental Technology and Management", Gu Tianxiang, etc., Vol.18No.3200) proposed to integrate "electronic experiment, microcomputer experiment and design, development, test The experimental link is built on a microcomputer (PC) platform to form a multi-functional comprehensive experimental platform", which increases the experimental process, improves the comprehensiveness of the equipment, and the flexibility and designability of the design. Fixed installation, the lines between the modules are arranged on the circuit board, just plug and unplug the wiring to complete, there is still a lack of practical links for assembly, and the modules used can only be used on this platform, which is comprehensive and flexible Performance, designability, and practical operability are still insufficient

[0011] 2.2.1 are all fixed installations, including the internal structure of the platform, circuits, experimental content and experimental methods, etc. are almost fixed, the relationship between the internal structure of the equipment is not easy to observe, the correlation with external equipment is poor, the experimental process is short, and the content is small , which is not conducive to cultivating students' design ability and innovation ability, and it is not easy to expand and update;

[0012] 2.2.2 The experimental content is relatively single, the structural components cannot be shared, and the interdisciplinary degree is not high. To meet the requirements of multidisciplinary comprehensive and design experiments, we can only rely on multiple platforms to achieve interdisciplinary interdisciplinary research, but this also involves excessive investment and occupation. The laboratory area is too large, the utilization rate of equipment is low, and the degree of correlation between disciplines cannot be well reflected. It is difficult for students to establish systematic correlation between courses, between subjects, and between courses and subjects through experiments. , which is not conducive to the cultivation of students' comprehensive and systematic analysis ability;

[0013] 2.2.3 Each experimental platform has one or several large cabinets, which is the main reason why many school laboratories are overcrowded but still cannot meet the needs of experimental teaching.

[0014] 2.2.4 The designability, changeability, innovation, observability, and manipulability of experiments are not high enough, especially for those complex and expensive experimental platforms, students can only choose to follow the experimental instructions or the ready-made ones provided by teachers. Steps, do some simple line connection, parameter setting and other operations. As for the internal structure, principle, structural relationship between components and mechanisms, as well as design and installation, it is difficult to obtain, which is not conducive to cultivating students' engineering practice ability

[0015] 2.2.5 Most of the components, especially the electrical and electronic components are installed in the cabinet, and students can only see their symbols on the panel, and these symbols are the same as those in the books. The experimental content and process are the same as the engineering practice content and The requirements are far apart, so the real effect of the experiment has not been exerted

[0016] 2.2.6 All experimental platforms are assembled with new components and new equipment. The price is high, which affects the number of equipment on the experimental platform, and students cannot let go of the most valuable experiments such as disassembly, installation, and debugging.

[0017] The above series of problems will have a certain impact on the experimental results, the actual utilization rate of the equipment and the investment benefits.
