[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure. Example 1

[0029] An experimental device for intrusion detection in industrial control systems, such as... Figures 1-8 As shown, it mainly consists of a main body 1, a flip cover 2, a support mechanism 5, a connecting mechanism 6, and various functional interfaces. The various parts work together to meet diverse experimental needs.

[0030] The main body 1 is made of high-strength engineering plastic material and manufactured by injection molding process. It has good pressure resistance and durability. Multiple sets of module plug-in plates 7 are evenly distributed on its surface. The channels at the four corners of the module plug-in plates 7 can ensure that the subsystem modules can be smoothly connected to the main control unit CortexM3 inside the main body 1. The main body 1 is also equipped with plug-in holes 8, start buttons 9 and adjustment knobs 10. The plug-in holes 8 are used to expand the functional modules, the start button 9 controls the opening and closing of the device, and the adjustment knobs 10 can adjust the experimental parameters.

[0031] The flip cover 2 is also made of high-strength engineering plastic and is rotatably connected to the main body 1 through the flip shaft 3. Multiple sets of insertion holes 4 are opened on the surface of the flip cover 2 to facilitate the installation of subsystem modules. Rubber pads 11 are fixed on both sides of the inner wall of the flip cover 2, which can effectively reduce the vibration generated when the flip cover 2 and the main body 1 are closed and protect the internal modules.

[0032] The support mechanism 5 is installed on both sides of the top of the flip cover 2, including a fixed plate 501, a flip support plate 502, a rotating shaft 503, a connecting groove 504, a limiting plate 505, a first sliding groove 506, a first bracket 507, a second bracket 508, a spring 509, a second sliding groove 510, a connecting block 511, a sliding block 512, a third sliding groove 513, and a first fastening bolt 514;

[0033] The fixed plate 501 is fixed to the flip cover 2 by the first fastening bolt 514. The flip support plate 502 is rotatably connected to the fixed plate 501 by the damping shaft 503, which can flexibly adjust the support angle. The damping shaft 503 uses a combination of friction plates and grease to generate damping force, ensuring that the flip support plate 502 is stable and reliable when supported.

[0034] The limiting plate 505 cooperates with the first sliding groove 506 and can slide inside the flip support plate 502. The first bracket 507 is fixed at the bottom of the limiting plate 505, and the second bracket 508 is fixed at the bottom of the flip support plate 502. The spring 509 connects the first bracket 507 and the second bracket 508. The second sliding groove 510 guides the sliding of the first bracket 507. The sliding block 512 is fixedly connected to the limiting plate 505 through the connecting block 511. The third sliding groove 513 provides sliding space for the connecting block 511, which facilitates the adjustment of the position of the limiting plate 505.

[0035] The connecting mechanism 6 is located on both sides of the main body 1 and consists of a locking plate 601, a rotating connecting plate 602, a limiting hole 603, and a second fastening bolt 604. The locking plate 601 is fixedly connected to the main body 1 by the second fastening bolt 604. The rotating connecting plate 602 is rotatably connected to the locking plate 601. Its end matches the connecting groove 504 of the support mechanism 5 and has a limiting hole 603, which cooperates with the limiting plate 505 to achieve a tight connection between the flip cover 2 and the main body 1.

[0036] The working principle of this utility model is as follows: When in use, the main body 1 is placed on the table, and the flip cover 2 and the main body 1 are opened to a suitable angle through the flip shaft 3. Then, the flip support plates 502 of the two sets of support mechanisms 5 are opened at a certain angle relative to the fixed plate 501 along the rotating shaft 503, so that the bottom of the flip support plate 502 contacts the table and plays a supporting role for the flip cover 2.

[0037] Specifically, the rotating shaft 503 is a damping rotating shaft, which achieves positioning through the damping force generated by the internal friction pads or grease. When an external force is applied, if the external force is less than the static friction force, the rotating shaft 503 remains stationary. When the external force exceeds the static friction force, the rotating shaft 503 rotates. In this process, static friction force is generated by squeezing the pads or grease. At this time, the static friction force is greater than the weight of the rotating shaft 503 itself and the gravity it bears, so that the flip support plate 502 can stably support the flip cover 2.

[0038] At this time, through the multiple insertion holes 4 opened on the flip cover 2 and the multiple subsystem module plug-in boards 7 set on the main body 1, different independent modules can be quickly inserted. Specifically, the hardware function modules of each subsystem are connected to the main control unit (Cortex M3) in a plug-and-play manner, and data transmission and command interaction are carried out through standardized communication protocols. For example, the sensor module and drive circuit of the intelligent access control system are connected to the main control unit to ensure normal communication.

[0039] The main control unit is installed inside the main body 1. The main control unit can be maintained by removing and installing the bottom cover of the main body 1. Each of the four corners of the multiple module plug-in boards 7 has a channel that leads into the interior of the main body 1. The connection end of the subsystem module can be inserted into the interior of the main body 1 through the channel to quickly connect with the active unit.

[0040] According to the experimental requirements, the parameters of each subsystem are configured. When using the energy-saving adaptive fan subsystem, the temperature threshold and fan speed adjustment parameters are set. During the experiment, students can operate and monitor the system through the human-computer interaction unit. In the intelligent wireless thermal printer subsystem, students can view the printing task status through the human-computer interaction interface. When an abnormal situation occurs, such as the temperature control module detecting that the temperature exceeds the threshold, the multi-system collaborative mechanism will automatically trigger the printer to output alarm logs.

[0041] If competition-level functional expansion is required, the reserved NB-IoT / LoRa communication compatible plug-in 8 can be used to connect the corresponding communication module to realize remote data transmission and control functions;

[0042] As mentioned above, this system solves the problem of fixed functions in traditional experimental equipment. Through modular architecture and plug-and-play combination, it achieves flexible expansion and customization of system functions, meeting the needs of different experimental projects and research topics. It overcomes the difficulties of interdisciplinary integration. The design of multi-system collaborative mechanisms and cross-professional subsystems enables the effective integration and application of knowledge from different disciplines within the system, promoting the cultivation of students' interdisciplinary thinking. The teaching adaptability design and supporting materials provide excellent teaching support for the development of innovative experiments and competitions in universities, helping to improve students' practical and innovative abilities and promoting the development of practical teaching in universities.

[0043] After use, remove all subsystem modules and manually flip the cover 2 to close it onto the main body 1. The rubber pad 11 on the inside of the cover 2 protects the contact between the cover 2 and the main body 1.

[0044] After the flip cover 2 is closed, the rotating connecting plate 602 in the connecting mechanism 6 on both sides of the main body 1 rotates to the inside of the connecting groove 504 on the fixed plate 501. Then, the sliding block 512 is slid manually. At this time, the sliding block 512 drives the limiting plate 505 to retract and slide through the connecting block 511. At this time, the spring 509 is stretched. Then, the flip support plate 502 is closed along the rotating shaft 503, so that the connecting groove 504 in the flip support plate 502 just covers the rotating connecting plate 602. At this time, the sliding block 512 is released. Under the reset action of the spring 509, the limiting plate 505 extends through the limiting hole 603 in the rotating connecting plate 602 and finally extends into the inside of the flip support plate 502.

[0045] As can be seen from the above, when not in use, the connection mechanism 6 and the support mechanism 5 work together to ensure a tight connection between the flip cover 2 and the main body 1, preventing the flip cover 2 from accidentally opening relative to the main body 1. This not only improves the overall portability but also allows the flip cover 2 to effectively protect the main body 1. Meanwhile, when in use, the support mechanism 5 provides stable support for the flip cover 2, providing stable support for the experimental process and ensuring the overall effect of the experiment.
