Description
Technical Field
[0001] This invention relates to the field of wireless network equipment security technology, specifically to an industrial control wireless network security protection system. Background Technology
[0002] With the rapid development of industrial informatization, the integration of industrialization and informatization is becoming increasingly profound. This integration can improve production efficiency, enhance production safety, and reduce production costs. Many industrial control systems utilize communication protocols and hardware / software systems from traditional networks, or connect directly to traditional networks in specific ways. This changes the previously closed working principle, causing industrial control equipment to be directly connected to the internet and exposed to various threats, posing potential harm to production safety and public safety. Therefore, people are actively seeking protective equipment and methods to counter these threats.
[0003] Currently, there are many types of existing industrial control wireless network security protection systems, but they do not provide security protection for the interfaces of the industrial control equipment itself or effectively limit the permissions of personnel. Industrial control data is not encrypted and is easily stolen and attacked by networks. It is easy for outsiders to maliciously plug and unplug interface lines, and it is difficult to hold them accountable. In some cases, excessively high temperatures during equipment operation can also lead to frequent equipment failures. Furthermore, external accidental impacts and fires can damage equipment and prevent the network from operating. These issues affect the security of industrial control networks from the perspective of the equipment itself. To address these problems, we propose an industrial control wireless network security protection system. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1
[0022] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides an industrial control wireless network security protection system, including an industrial control computer body 1. Antenna interfaces 4 are fixedly installed on both sides of one end face of the industrial control computer body 1. The antenna interfaces 4 are connected to wireless antennas 2. Heat sinks 3 are fixedly connected to the outside of the industrial control computer body 1. A USB interface 6, a media interface 7, and a network interface 8 are respectively provided on one side of the industrial control computer body 1 from top to bottom. Sensing components 9 are respectively provided between and on both sides of the media interfaces 7. Side support strips 10 are fixedly connected to one end of the two side sensing components 9. Several limiting strips 11 are fixedly connected to the opposite side of the side support strips 10. A middle support strip 12 is fixedly connected to one end of the middle sensing component 9. Several auxiliary limiting strips 18 are fixedly connected to both sides of the middle support strip 12.
[0023] A cooling fan 16 is fixedly installed in the middle of the other end face of the industrial computer body 1. Buzzers 17 are fixedly installed in the industrial computer body 1 on both sides of the cooling fan 16. Hinges 13 are fixedly connected to the bottom of both sides of the industrial computer body 1. A sliding plate 14 is hinged to the hinge 13. A protective plate 15 is hinged to the end of the sliding plate 14 away from the hinge 13. The industrial control computer 1 connects to mains power via power interface 5 and a power cord. It connects to the network via network interface 8 and a network cable, or via antenna interface 4 and a wireless antenna 2. When the network cable is connected, the elasticity of the limiting strip 11 allows for angle adjustment. The auxiliary limiting strip 18 is then moved to position it on either side of the network cable. Simultaneously, the C-shaped structure of the auxiliary and limiting strips 11 wraps around and restricts the network cable. A lock is then inserted through the round hole 111 to lock the auxiliary and limiting strips 18, thus protecting the network cable. Only authorized personnel with key access can operate the network cable, ensuring network security. The same method can be used to... The wiring of USB interface 6 and media interface 7 is protected separately to ensure safety and prevent malicious plugging and unplugging of interface lines by external personnel. When an external person attempts to plug or unplug an interface, the limiting strip 11 and auxiliary limiting strip 18 forming a circular structure limit the wire body of the interface. When an external person attempts to plug or unplug an interface with brute force, the greater external force pulls the side support strip 10 and the middle support strip 12. The side support strip 10 and the middle support strip 12 drive the fixed sensing component 9 to move. When the external force reaches the threshold, the pressure signal is transmitted to the microcontroller installed inside the industrial control computer body 1. The microcontroller transmits the signal to the buzzer 17, which activates and emits an alarm signal to warn the surrounding personnel and prevent external personnel from attempting to plug or unplug interfaces with brute force, further ensuring the security of the wireless network of the industrial control computer body 1.
[0024] Example 2
[0025] Reference Figure 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, each of the two protective plates 15 has a buckle and a slot at the end away from the hinge. Through the cooperation of the buckle and the slot, after the two protective plates 15 are unfolded, the buckle and the slot limit and fix the spliced protective plates 15 to ensure consistency after unfolding. At the same time, the protective plates 15 protect the industrial control computer body 1 and prevent external forces from directly impacting the industrial control computer body 1.
[0026] Specifically, the limiting strip 11 has a Y-shaped structure. The C-shaped structure of the limiting strip 11 is made of a metal sheet wrapped around a rubber strip, and the rectangular structure of the limiting strip 11 is made of an elastic rubber strip. Rectangular metal plates are fixedly connected to both sides of the C-shaped structure of the limiting strip 11, and a circular hole 111 is opened in the middle of the metal plate. The material of the rectangular metal plate ensures the tightness of the connection between the auxiliary limiting strip 18 and the limiting strip 11.
[0027] Specifically, the limiting strip 11 and the auxiliary limiting strip 18 have identical structures and materials. They are symmetrically arranged, with the center of the ring formed by the limiting strip 11 and the auxiliary limiting strip 18 located at the centers of the USB interface 6, media interface 7, and network interface 8, respectively. By moving the limiting strip 11, its elasticity allows for easy angle adjustment. Moving the auxiliary limiting strip 18 positions it on either side of the network cable. Simultaneously, the auxiliary and auxiliary limiting strips 18 wrap around the network cable through their C-shaped ends, securing them. A lock is then inserted through the circular hole 111 to lock both the auxiliary and auxiliary limiting strips 18, thus protecting the network cable. Only authorized personnel with keys can operate the network cable, ensuring network security.
[0028] Specifically, a groove 141 is recessed on one side of the sliding plate 14, and a sliding block 142 is slidably mounted in the groove 141. A rotating plate 143 is fixedly connected to one end of each sliding block 142, and a protective plate 15 is hinged to one end of the rotating plate 143. By pulling the protective plate 15, the rotating plate 143 is moved, causing the fixed sliding block 142 to slide within the groove 141, thereby moving the protective plate 15 to its outermost position. Then, the sliding plate 14 is rotated to a position parallel to the two side walls of the industrial computer body 1, and finally, the protective plate 15 is rotated to a position parallel to the top wall of the industrial computer body 1. Simultaneously, the locking mechanism of the protective plate 15 ensures protection of the top wall of the industrial computer body 1, while the sliding plate 14 protects the side walls of the industrial computer body 1.
[0029] Furthermore, the slide 141 is a T-shaped groove, and the sliding plate 14 is located in the middle of both sides of the industrial control computer body 1.
[0030] Specifically, the sensing component 9 includes a support cylinder 91, a movable rod 92, a limiting plate 93, and an annular pressure sensor 94. One end of the support cylinder 91 is fixedly connected to the industrial control computer body 1. The movable rod 92 is slidably sleeved inside the support cylinder 91. One end of the movable rod 92 is fixedly connected to the limiting plate 93. The limiting plate 93 is movably disposed inside the support cylinder 91. The annular pressure sensor 94 is fixedly connected to the inner wall of the other end of the support cylinder 91. The movable rod 92 is movably sleeved inside the annular pressure sensor 94. When an external person attempts to forcefully plug or unplug the device, the significant external force pulls the side support bar 10 and the central support bar 12. The side support bar 10 and the central support bar 12 then move the movable rod 92 of the fixed sensing component 9. The movable rod 92 moves the fixed limiting plate 93. When the movable rod 92 moves to its end within the support cylinder 91, the limiting plate 93 abuts against the annular pressure sensor 94. The external force applies pressure to the annular pressure sensor 94 through the limiting plate 93. When the pressure reaches the threshold, the annular pressure sensor 94 transmits a signal to the microcontroller installed inside the industrial control computer 1. The microcontroller then transmits a signal to the buzzer 17, which activates and emits an alarm signal to alert surrounding personnel and prevent external personnel from attempting to forcefully plug or unplug the device, further ensuring the security of the wireless network of the industrial control computer 1.
[0031] Example 3
[0032] Reference Figure 1-5This is the third embodiment of the present invention, based on the above two embodiments. In use, the industrial control computer 1 is connected to mains power via power interface 5 and power cord. The industrial control computer 1 connects to the network via network interface 8 and network cable, or via antenna interface 4 and wireless antenna 2. When the network cable is connected, the elasticity of the limiting strip 11 allows for angle adjustment. Then, the auxiliary limiting strip 18 is moved to position it on both sides of the network cable. Simultaneously, the auxiliary limiting strip 18 and the limiting strip 11 wrap around and limit the network cable through the C-shaped structure. A lock is then used through the round hole 111 to lock the auxiliary limiting strip 18 and the limiting strip 11, thus protecting the network cable. Only authorized personnel with keys can operate the network cable, ensuring network security. The same method can be used to protect the connections of the USB interface 6 and media interface 7, similarly ensuring security and preventing... To prevent unauthorized plugging and unplugging of interface lines by external personnel, when such personnel attempt to plug or unplug the interface, the limiting strip 11 and auxiliary limiting strip 18, forming a circular structure, provide limiting protection for the cable body. When external personnel attempt to use brute force to plug or unplug, the greater external force pulls the side support strip 10 and the middle support strip 12. The side support strip 10 and the middle support strip 12 drive the movable rod 92 of the fixed sensing component 9 to move. The movable rod 92 drives the fixed limiting plate 93 to move. When the movable rod 92 moves to the end within the support cylinder 91, the limiting plate 93 abuts against the annular pressure sensor 94. The external force applies pressure to the annular pressure sensor 94 through the limiting plate 93. When the pressure reaches the threshold, the annular pressure sensor 94 transmits a signal to the microcontroller installed inside the industrial control computer 1. The microcontroller transmits a signal to the buzzer 17, which activates and emits an alarm signal to warn surrounding personnel, preventing external personnel from attempting to use brute force to plug or unplug, and further ensuring the security of the wireless network of the industrial control computer 1.
