Description

Technical Field

[0001] This invention relates to the field of automatic hot standby switching technology for EAP primary and backup servers, and particularly to an EAP primary and backup server capable of automatic hot standby switching and its usage method. Background Technology

[0002] The EAP primary and backup servers with automatic hot standby switching are a highly available and redundant authentication system consisting of two servers equipped with EAP authentication services. The system adopts a one-primary-one-backup operating architecture. The primary server normally undertakes all EAP access authentication, authorization and billing services, while the backup server is continuously powered on and running, synchronizing the primary server's authentication configuration, user policies and session data in real time, and is in a hot standby state.

[0003] Although existing primary and backup servers can perform automatic hot standby switching, the hot standby switching of existing devices mainly relies on pre-written pre-defined programs. However, vulnerabilities in the program code or external influences can cause unexpected errors in the program execution, which may lead to hot standby switching failures. This can easily affect the reliability and stability of the device's automatic hot standby switching, thereby impacting the device's market competitiveness. Furthermore, the device has poor adaptability to continuous production scenarios, and the existing devices have fixed spacing between the primary and backup servers. This means that when the primary server is fully loaded and generates a large amount of heat, the nearby backup server is continuously affected by the heat, leading to increased ambient temperature, accelerated component aging, and ultimately, high-temperature anomalies in the backup server, affecting the overall operational stability of the primary and backup servers. Therefore, this application provides an EAP primary and backup server with automatic hot standby switching and its usage method to meet the requirements. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an EAP primary / backup server with automatic hot standby switching and its usage method. This solves the problem that the automatic hot standby switching between the primary and backup servers in existing devices relies on software program code, which is subject to numerous factors that hinder successful control of the automatic hot standby switching. These factors can negatively impact the reliability, stability, market competitiveness, and adaptability to various production scenarios of the device's automatic hot standby switching. Furthermore, the fixed spacing between the primary and backup servers in existing devices makes the backup server susceptible to continuous heat from the primary server, leading to abnormally high temperatures and consequently affecting the overall stability of the primary and backup server system.

[0008] Preferably, an electromagnet is fixedly connected to the inner wall of the electromagnetic circular hole, one end of the electromagnet is provided with an electromagnetic wire, an electromagnetic relay is installed on the electromagnet through the electromagnetic wire, and a short wire for transmitting electrical signals is provided on one side of the electromagnetic relay.

[0009] Preferably, the electromagnetic relay is equipped with an expansion dock via an electrical signal transmission short line, one side of which is provided with an electrical signal output line, and a rigid connector is fixedly connected to the back of the expansion dock.

[0010] Preferably, the server tension module includes a solid base block, a U-shaped plate is fixedly connected to the front of the solid base block, a base plate is fixedly connected to the back of the U-shaped plate, a temperature monitor is provided on the back of the base plate, and the temperature monitor is threadedly connected to the base plate by a temperature monitor bolt.

[0011] Preferably, a first top base plate is fixedly connected to the top of the solid base block, a large U-shaped plate is fixedly connected to one side of the solid base block, a side sealing plate is provided on one side of the large U-shaped plate, and the large U-shaped plate is threadedly connected to the side sealing plate by a side sealing plate bolt.

[0012] Preferably, a lead screw circular hole is provided on one side of the side sealing plate, and a servo motor is provided on the other side of the side sealing plate. The servo motor is threadedly connected to the side sealing plate through a servo motor bolt. A track rod and a lead screw are provided sequentially from left to right on one side of the side sealing plate. The track rod is threadedly connected to the side sealing plate through a track rod bolt. The lead screw and the lead screw circular hole are mutually compatible.

[0013] Preferably, a pivot hole is provided on the other side of the large U-shaped plate, and a pivot is provided inside the pivot hole. The large U-shaped plate and the lead screw are adapted to each other. A track rod sleeve is provided on the surface of the track rod, and a lead screw sleeve is provided on the surface of the lead screw. A vertical connecting short plate is fixedly connected to the upper surface of the track rod sleeve and the lead screw sleeve. A second top base plate is fixedly connected to the top of the vertical connecting short plate.

[0014] A method for using an EAP primary / standby server with automatic hot standby switching includes the following steps: Step 1: The primary server casing and the backup server casing are responsible for protecting their respective internal displays and server assemblies. Personnel view the data inside the server through the displays. The setup and start buttons on the control panel are used to configure and start the server. The displays are connected via a monitor cable to configure or view the server assembly. The input and output terminals are for receiving and outputting electrical signals. The auxiliary automatic switching module performs automatic hot standby switching mechanically. In the event of a primary server failure, the backup server can be quickly started. The electrical signal input line is responsible for transmitting external electrical signals to the input terminal, which then inputs them into the server assembly. The server distance module can push the backup server away when the primary server's heat dissipation temperature exceeds the specified temperature, thereby increasing the distance between the two servers. This reduces the risk of the backup server prematurely triggering a high-temperature alarm or becoming unstable due to overheating, thus helping to improve the overall stability of the primary and backup server system. Step 2: When the main server is working normally, it means that the server assembly is outputting electrical signals through the output terminal. The output electrical signals can be transmitted to the expansion dock through the rigid connector. The short electrical signal transmission line on the side of the expansion dock can transmit the electrical signals to the electromagnetic relay. The electrical signal output line on the side of the expansion dock can transmit the electrical signals to the outside without loss. The expansion dock is designed to allow the electrical signals to be transmitted to the outside without loss, and at the same time, the electrical signals can be transmitted to the electromagnetic relay to be converted into electricity. The electricity is transmitted to the electromagnet through the electromagnetic wire. When the electromagnet is energized, it will generate magnetic force, so the magnetic force can attract the connecting plate. At this time, the spring is compressed and deformed. However, once there is no electrical signal output from the output terminal, the electromagnet has no magnetic force. Therefore, the electromagnet will pop out the connecting plate, which will then move in the slide rail through the rotating wheel. This allows the rubber block to trigger the start button on the standby server to start synchronously. Step 3: The temperature monitor is responsible for monitoring the heat dissipation of the main server. If the heat dissipation is too high, the temperature monitor will be triggered to issue an alarm and transmit a start signal to the servo motor. After receiving the signal, the servo motor will start, which will drive the lead screw to rotate. The lead screw sleeve and the lead screw are matched. The rotation of the lead screw will drive the lead screw sleeve to move forward or backward. The lead screw sleeve and the track rod are also matched. The forward or backward movement of the lead screw sleeve will drive the second top base plate and the track rod sleeve to move. The track rod sleeve moves on the track rod. At the same time, the cooperation of the track rod sleeve and the track rod sleeve is to limit the movement of the second top base plate and prevent it from flipping over.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, an auxiliary automatic switching module is set up. This module realizes the diversion of line signals through mechanical means. While maintaining the normal transmission of the original operating condition signals, it uses the diverted signals to control the electromagnetic adsorption mechanism. Relying on the main unit's operating condition output signal, it accurately identifies equipment failures. After a failure, it can automatically start the backup main unit, thereby ultimately realizing automatic hot standby switching between the main and backup units. This can improve the reliability and stability of the automatic hot standby switching of the device to a certain extent, thereby increasing the device's competitiveness in the market and helping to improve the device's adaptability to continuous production scenarios.

[0016] By setting up a server distance module, this module can monitor whether the heat emitted by the server during operation exceeds the standard. If it exceeds the standard, the standby server can be pushed a little distance away from the main server. This can reduce the thermal interference caused by the heat radiated outward from the main server to the standby server to a certain extent, avoid the heat accumulation causing the ambient temperature of the standby server to rise, reduce the risk of the standby server prematurely triggering high temperature alarms and unstable operation due to overheating, and thus help improve the overall stability of the main and standby servers.

[0017] In summary, this invention has the advantages of enabling automatic hot standby switching via mechanical means, improving the reliability, stability, market competitiveness, and adaptability of the device in automatic hot standby switching, as well as its adaptability to continuous production scenarios. It can also automatically adjust the distance between the primary and backup servers when the primary server overheats, reducing the continuous impact of high temperature on the backup server and ensuring the overall stability of the primary and backup server operation.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an EAP primary / backup server with automatic hot standby switching and a method of use, including a primary server shell 1 and a backup server shell 2. The back of the backup server shell 2 is provided with an auxiliary automatic switching module 3. Both the primary server shell 1 and the backup server shell 2 are provided with a display 4. The back of the display 4 is provided with a control panel 5. From left to right, the back of the display 4 is provided with a setting button 6 and a start button 7. The front of the display 4 is provided with a display connection cable 8. The display 4 is connected to a server assembly 9 through the display connection cable 8. From top to bottom, the front of the server assembly 9 is provided with an input terminal 10 and an output terminal 11. The front of the input terminal 10 is provided with an electrical signal input line 12. The bottom of both the primary server shell 1 and the backup server shell 2 is provided with a server tension module 13.

[0027] The auxiliary automatic switching module 3 is installed on the standby server shell 2. The control panel 5 and the display 4 are integrated. The setting button 6 and the start button 7 are both connected to the control panel 5. The display connection cable 8 is installed between the display 4 and the server assembly 9. The display 4 and the server assembly 9 are installed inside the main server shell 1 and the standby server shell 2. The input terminal 10 and the output terminal 11 are both integrated with the server assembly 9. The electrical signal input line 12 is installed on the input terminal 10. The server tension module 13 is located at the bottom of the main server shell 1 and the standby server shell 2.

[0028] The main server casing 1 and the backup server casing 2 are responsible for protecting their respective internal displays 4 and server assemblies 9. Personnel view the data inside the server through the display 4. The setting button 6 and start button 7 on the control panel 5 can be used to set up and start the server. The display 4 is used to set up or view the server assembly 9 through the display connection cable 8. The input terminal 10 and output terminal 11 are for receiving and outputting electrical signals. The auxiliary automatic switching module 3 performs automatic hot standby switching through mechanical means. After the main server fails, the backup server can be quickly started. The electrical signal input line 12 is responsible for transmitting external electrical signals to the input terminal 10, which in turn inputs them into the server assembly 9. The server distance module 13 can push the backup server away when the temperature of the main server exceeds the specified temperature, thereby increasing the distance between the two and reducing the risk of the backup server prematurely triggering a high temperature alarm or unstable operation due to overheating. This helps to improve the overall stability of the main and backup server system.

[0029] like Figures 3 to 6 As shown, in this embodiment, the auxiliary automatic switching module 3 includes a slide rail 301. The slide rail 301 is threadedly connected to the backup server housing 2 via slide rail bolts. A C-shaped plate 302 is fixedly connected to the side of the slide rail 301. An electromagnetic circular hole is opened on the back of the C-shaped plate 302. A slider 303 is provided inside the slide rail 301.

[0030] The top and bottom of the slider 303 are provided with wheel grooves, and the inside of the wheel grooves is provided with a rotating wheel 304. A connecting plate 305 is fixedly connected to one side of the slider 303. A trigger block 306 is fixedly connected to the front of the connecting plate 305. A rubber block 307 is provided on the front of the trigger block 306. A spring 308 is fixedly connected to the back of the connecting plate 305.

[0031] An electromagnet 309 is fixedly connected to the inner wall of the electromagnetic circular hole. An electromagnetic wire 310 is provided at one end of the electromagnet 309. An electromagnetic relay 311 is installed on the electromagnet 309 through the electromagnetic wire 310. A short line 312 for transmitting electrical signals is provided on one side of the electromagnetic relay 311.

[0032] The electromagnetic relay 311 is equipped with an expansion dock 313 via an electrical signal transmission short line 312. An electrical signal output line 314 is provided on one side of the electrical signal transmission short line 312, and a rigid connector 315 is fixedly connected to the back of the expansion dock 313.

[0033] The slide rail 301 is fixed to the backup server housing 2 by slide rail bolts. The backup server housing 2 is welded to the slide rail 301. The slider 303 is placed inside the slide rail 301. The rotating wheel 304 is installed in the wheel groove of the slider 303. The connecting plate 305 is welded to the slider 303. The trigger block 306 is welded to the front of the connecting plate 305. The spring 308 is welded between the connecting plate 305 and the C-shaped plate 302. The rubber block 307 and the trigger block 306 are integrally connected. The outer surface of the electromagnet 309 is welded to the inner wall of the electromagnetic circular hole of the connecting plate 305. The electromagnetic wire 310 is installed between the electromagnet 309 and the electromagnetic relay 311. The electrical signal transmission short wire 312 is installed between the electromagnetic relay 311 and the expansion dock 313. The electrical signal output line 314 is installed at the expansion dock 313. The rigid connector 315 and the expansion dock 313 are integrally formed. The expansion docks 313 are welded together with each other.

[0034] When the main server is working normally, it means that the server assembly 9 is outputting an electrical signal through the output terminal 11. This output electrical signal can be transmitted to the expansion dock 313 through the rigid connector 315. The electrical signal transmission short cable 312 on the side of the expansion dock 313 can transmit the electrical signal to the electromagnetic relay 311. The electrical signal output cable 314 on the side of the expansion dock 313 can transmit the electrical signal to the outside without loss. The expansion dock 313 is designed to allow the electrical signal to be transmitted to the outside without loss, while also allowing the electrical signal to be converted into electrical signals by the electromagnetic relay 311. Electricity is transmitted to the electromagnet 309 through the electromagnetic wire 310. When the electromagnet 309 is connected to electricity, it will generate a magnetic force, which can attract the connecting plate 305. At this time, the spring 308 is compressed and deformed. However, once there is no electrical signal from the output terminal 11, the electromagnet 309 will have no magnetic force, so the electromagnet 309 will pop out the connecting plate 305. Then, the connecting plate 305 will move in the slide rail 301 through the rotating wheel 304, so that the rubber block 307 can trigger the start button 7 of the backup server to start the start button 7 synchronously.

[0035] By using the auxiliary automatic switching module 3, the module achieves line signal diversion through mechanical means. While maintaining the normal transmission of the original operating condition signal, it uses the diverted signal to control the electromagnetic adsorption mechanism. Relying on the main unit's operating condition output signal, it accurately identifies equipment failures. After a failure, it can automatically start the backup main unit, thereby ultimately achieving automatic hot standby switching between the main and backup units. This can improve the reliability and stability of the automatic hot standby switching of the device to a certain extent, thereby increasing the device's competitiveness in the market and helping to improve the device's adaptability to continuous production scenarios.

[0041] Temperature monitor 1304 is responsible for monitoring the heat dissipation of the main server. If the heat dissipation is too high, temperature monitor 1304 will be triggered to issue an alarm and transmit a start signal to servo motor 1308. After receiving the signal, servo motor 1308 will start. The start of servo motor 1308 will drive lead screw 1310 to rotate. Lead screw sleeve 1313 and lead screw 1310 are matched. The rotation of lead screw 1310 will drive lead screw sleeve 1313 to move forward or backward. Lead screw sleeve 1313 and track rod 1309 are also matched.

[0042] By setting up the server spacing module 13, this module can monitor whether the heat emitted by the server during operation exceeds the standard. If it exceeds the standard, the backup server can be pushed a little distance away from the main server. This can reduce the thermal interference caused by the heat radiated outward by the main server to the backup server to a certain extent, avoid the heat accumulation causing the ambient temperature of the backup server to rise, reduce the risk of the backup server prematurely triggering a high temperature alarm and unstable operation due to overheating, and thus help improve the overall stability of the main and backup server operation.

[0043] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0044] A method for using an EAP primary / standby server with automatic hot standby switching includes the following steps: Step 1: The main server casing 1 and the backup server casing 2 are responsible for protecting their respective internal displays 4 and server assemblies 9. Personnel can view the data inside the server through the display 4. The setting button 6 and start button 7 on the control panel 5 can be used to set up and start the server. The display 4 is used to set up or view the server assembly 9 through the display connection cable 8. The input terminal 10 and output terminal 11 are used to receive and output electrical signals. The auxiliary automatic switching module 3 performs automatic hot standby switching through mechanical means. After the main server fails, the backup server can be quickly started. The electrical signal input line 12 is responsible for transmitting external electrical signals to the input terminal 10, which is then input into the server assembly 9. The server distance module 13 can push the backup server away when the temperature of the main server exceeds the specified temperature, thereby increasing the distance between the two and reducing the risk of the backup server prematurely triggering a high temperature alarm or unstable operation due to overheating. This helps to improve the overall stability of the main and backup server operation. Step 2: When the main server is working normally, it indicates that the server assembly 9 is outputting electrical signals through output terminal 11. These output signals can be transmitted to the expansion dock 313 via the rigid connector 315. The short electrical signal transmission cable 312 on the side of the expansion dock 313 can then transmit the electrical signals to the electromagnetic relay 311. The electrical signal output cable 314 on the side of the expansion dock 313 can transmit the electrical signals to the outside without loss. The expansion dock 313 is designed to allow for lossless transmission of electrical signals to the outside while simultaneously transmitting the signals to the electromagnetic relay 311 for conversion. Electricity is transmitted through the electromagnetic wire 310 to the electromagnet 309. When the electromagnet 309 is connected to electricity, it will generate a magnetic force. Therefore, the magnetic force can attract the connecting plate 305. At this time, the spring 308 is compressed and deformed. However, once there is no electrical signal transmitted from the output terminal 11, the electromagnet 309 will have no magnetic force. Therefore, the electromagnet 309 will pop out the connecting plate 305, which will then move in the slide rail 301 through the rotating wheel 304. This allows the rubber block 307 to trigger the start button 7 of the backup server to start the start button 7 synchronously. Step 3: Temperature monitor 1304 monitors the heat dissipation of the main server. If the heat dissipation is too high, temperature monitor 1304 will be triggered to issue an alarm and transmit a start signal to servo motor 1308. After receiving the signal, servo motor 1308 will start. The start of servo motor 1308 will drive lead screw 1310 to rotate. Lead screw sleeve 1313 and lead screw 1310 are matched. The rotation of lead screw 1310 will drive lead screw sleeve 1313 to move forward or backward. Lead screw sleeve 1313 and track rod 1309 are also matched. The forward or backward movement of lead screw sleeve 1313 will drive the second top base plate 1315 and track rod sleeve 1312 to move. Track rod sleeve 1312 moves on track rod 1309. At the same time, the cooperation of track rod sleeve 1312 is to limit the movement of the second top base plate 1315 and prevent it from flipping.

[0045] The technical solution provided by this invention: The main server casing 1 and the backup server casing 2 are responsible for protecting their respective internal displays 4 and server assemblies 9. Personnel view the data inside the server through the displays 4. The setting button 6 and start button 7 on the control panel 5 can be used to set up and start the server. The displays 4 are used to set up or view the server assembly 9 via the display connection cable 8. The input terminal 10 and output terminal 11 are for receiving and outputting electrical signals. The auxiliary automatic switching module 3 performs automatic hot standby switching mechanically, quickly starting the backup server after the main server fails. The electrical signal input line 12 is responsible for transmitting external electrical signals to the input terminal 10, thereby inputting them into the server assembly 9. The server distance module 13 can push the standby server away when the main server's temperature exceeds the specified temperature, increasing the distance between them. This reduces the risk of the standby server prematurely triggering a high-temperature alarm or becoming unstable due to overheating, thus improving the overall stability of the main and standby servers. When the main server is working normally, it means that the server assembly 9 is outputting an electrical signal through the output terminal 11. This output signal can be transmitted to the expansion dock 313 through the rigid connector 315. The short electrical signal transmission line 312 on the side of the expansion dock 313 can transmit the electrical signal to the electromagnetic relay 311, and the electrical signal output line 314 on the side of the expansion dock 313 can transmit the electrical signal to the outside without modification. The expansion dock 313 is designed to allow electrical signals to be transmitted to the outside world without loss, while simultaneously transmitting the signals to the electromagnetic relay 311 for conversion into electricity. This electricity is then transmitted via the electromagnetic wire 310 to the electromagnet 309. When the electromagnet 309 is energized, it generates a magnetic force, which attracts the connecting plate 305, causing the spring 308 to compress and deform. However, if no electrical signal is transmitted from the output terminal 11, the electromagnet 309 loses its magnetic force, thus ejecting the connecting plate 305. This causes the connecting plate 305 to move along the slide rail 301 via the rotating wheel 304, thereby triggering the start button 7 on the backup server to simultaneously activate the start button 7. Temperature monitor 1304 monitors the heat dissipation of the main server. If the heat dissipation is too high, temperature monitor 1304 is triggered and an alarm is sent to servo motor 1308. Upon receiving the signal, servo motor 1308 starts, which in turn drives lead screw 1310 to rotate. Lead screw sleeve 1313 and lead screw 1310 are paired; rotation of lead screw 1310 drives lead screw sleeve 1313 to move forward or backward. Lead screw sleeve 1313 and track rod 1309 are also paired; forward or backward movement of lead screw sleeve 1313 drives the second top base plate 1315 and track rod sleeve 1312 to move. Track rod sleeve 1312 moves on track rod 1309. Simultaneously...The use of track sleeve 1312 and track sleeve 1312 together is to restrict the movement of the second top base plate 1315 and prevent it from overturning.

10. The method of using the EAP primary / standby server with automatic hot standby switching according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: The main server shell (1) and the backup server shell (2) are responsible for protecting the internal display (4) and server assembly (9). Personnel can see the data inside the server through the display (4). The setting button (6) and start button (7) on the control panel (5) can be used to set up and start the server. The display (4) is used to set up or view the server assembly (9) through the display connection cable (8). The input end (10) and output end (11) are for receiving and outputting electrical signals. The auxiliary automatic switching module (3) performs automatic hot standby switching in a mechanical way. After the main server fails, the backup server can be started quickly. The electrical signal input line (12) is responsible for transmitting external electrical signals to the input end (10) and inputting them into the server assembly (9). The server pull distance module (13) can push the backup server away when the temperature of the main server exceeds the standard temperature, thereby increasing the distance between the two and reducing the risk of the backup server prematurely triggering a high temperature alarm and unstable operation due to heat. This helps to improve the overall stability of the main and backup servers. Step 2: When the main server is working normally, it means that the server assembly (9) is outputting electrical signals through the output terminal (11). The output electrical signals can be transmitted to the expansion dock (313) through the rigid connector (315). The electrical signal transmission short line (312) on the side of the expansion dock (313) can transmit the electrical signals to the electromagnetic relay (311). The electrical signal output line (314) on the side of the expansion dock (313) can transmit the electrical signals to the outside without loss. The expansion dock (313) is designed so that the electrical signals can be transmitted to the outside without loss, and at the same time, the electrical signals can be transmitted to the electromagnetic relay (311) to be converted into electricity. The signal is transmitted through the electromagnetic wire (310) to the electromagnet (309). When the electromagnet (309) is connected to the power supply, it will generate a magnetic force. Therefore, the magnetic force can attract the connecting plate (305). At this time, the spring (308) is compressed and deformed. However, once there is no electrical signal transmitted from the output end (11), the electromagnet (309) will not have a magnetic force. Therefore, the electromagnet (309) will pop out the connecting plate (305), and then the connecting plate (305) will move in the slide rail (301) through the rotating wheel (304). This allows the rubber block (307) to trigger the start button (7) of the backup server to start the start button (7) simultaneously. Step 3: The temperature monitor (1304) is responsible for monitoring the heat dissipation of the main server. If the heat dissipation is too high, the temperature monitor (1304) will be triggered to issue an alarm and transmit a start signal to the servo motor (1308). After receiving the signal, the servo motor (1308) will start. The start of the servo motor (1308) will drive the lead screw (1310) to rotate. The lead screw sleeve (1313) and the lead screw (1310) are matched. The rotation of the lead screw (1310) will drive the lead screw... The rod sleeve (1313) moves forward or backward, and the lead screw sleeve (1313) and the track rod (1309) are also matched. The forward or backward movement of the lead screw sleeve (1313) will drive the second top base plate (1315) and the track rod sleeve (1312) to move. The track rod sleeve (1312) moves on the track rod (1309). At the same time, the cooperation between the track rod sleeve (1312) and the track rod sleeve (1312) is to limit the movement state of the second top base plate (1315) and prevent it from flipping.
