Description

technical field [0001] The invention mainly relates to a teaching system, in particular to a network-based constant pressure water supply group teaching system. Background technique [0002] With the development of frequency conversion speed regulation technology, the constant pressure water supply system based on PLC and frequency converter has gradually replaced the original water tower water supply system. Constant-pressure water supply has been widely used in factories, mines, enterprises, domestic and fire-fighting water supply systems. However, there are few types of training devices for constant-pressure water supply, and the comprehensive practical teaching system for regional water supply constant-pressure water supply groups is even scarcer in China. It is one of the reasons why college students' comprehensive analysis and problem-solving abilities are relatively weak. [0003] The existing constant pressure water supply teaching equipment mainly has the following...

Problems solved by technology

Constant-pressure water supply has been widely used in factories, mines, enterprises, domestic and fire-fighting water supply systems. However, there are few types of training devices for constant-pressure water supply, and the comprehensive practical teaching system for regional water supply constant-pressure water supply groups is even scarcer in China. It is one of the reasons why college students' ability to comprehensively analyze and solve problems is weak

[0003] The existing constant pressure water supply teaching equipment mainly has the following problems: the technical content is not high, or the integration of new technologies is low, and students do not have a comprehensive and in-depth understanding of the comprehensive application of new technologies; Secondary development, but simply move the actual constant pressure water supply equipment into the laboratory completely and intact, and only one start button and one stop button can be operated by students. Such equipment can only be demonstrated to students. It cannot be used by students for actual hands-on operation, and students' hands-on ability cannot be improved; some equipment developers have realized the needs of students for actual hands-on operation, but because the developers are not front-line teachers, they have not carried out secondary development for the actual teaching. Some of them have been made into simple teaching aids without the characteristics of actual equipment, and some are still actual equipment, which is not suitable for students to operate. Every time a student completes a teaching project, it is equivalent to an installation and debugging of the equipment, which will inevitably cause teaching problems. The efficiency is low, which is not conducive to the flexible organization of teaching; the essential difference between the actual equipment and the teaching equipment has not been found, and the students can only make repeated connections on the terminals of the actual spare parts, resulting in a high failure rate of the equipment, high maintenance costs, and long service life It is short, which seriously affects the normal teaching; there is a big gap between the electrical drawings and the actual control system, and it is difficult for students to understand and master the functions, distribution locations, and sources of contacts of each information point in a short period of time, which will inevitably result in teaching efficiency. Low; cannot form a group, cannot connect to a network, cannot realize remote monitoring and Internet ultra-remote monitoring; the function of the equipment is single, and there are few practical training items that can be issued, so the utilization rate of the equipment is low, and the limited teaching resources cannot be maximized The social and economic benefits; the communication between the various modules of the equipment is realized by plugging and unplugging the communication cables, and the plugging and unplugging of the cables can only be carried out in the case of a power failure. The communication interface reduces the efficiency of training and affects the normal progress of teaching
