Description

Technical Field

[0001] This utility model relates to the technical field of power failure protection equipment for cryptographic machines, and more specifically, to a cryptographic machine with power failure protection function. Background Technology

[0002] Server cryptographic machines are developed for applications requiring high security, high speed, and high performance. They feature comprehensive functions, high algorithm processing speed, and large concurrent workload capacity. As a high-end commercial basic cryptographic product, it can provide high-performance data encryption / decryption services for secure information transmission systems, and serve as a primary cryptographic device and core component for host data security storage systems, identity authentication systems, and symmetric and asymmetric key management systems, possessing broad system application potential. It can be widely used in secure business application systems in industries such as banking, insurance, securities, transportation, postal services, e-commerce, and mobile communications.

[0003] To meet the high computational demands and large concurrent capacity of server cryptographic machines, similar to servers, the motherboard of a server cryptographic machine typically needs to house multiple CPUs, memory modules, and hard drives. Additionally, considering heat dissipation, multiple ventilation holes need to be designed on the I / O panel. Due to the large number of these components, a single power supply cannot meet the power requirements of multiple components, so usually two or more power supplies are designed. After prolonged operation, existing server cryptographic machines are prone to voltage anomalies due to the large number of internal components. High currents can damage these components, and individual components may also be damaged when operating at high temperatures. Therefore, a dedicated power-off protection function needs to be designed for server cryptographic machines. Utility Model Content

[0004] The purpose of this invention is to provide a cryptographic machine with a power-off protection function. The power-off protection function of this cryptographic machine can be triggered by a detected large current or high temperature, and the power supply path is disconnected through a relay. The designed adapter can be used with multiple power supplies of the server cryptographic machine, and has good applicability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cryptographic device with power failure protection includes a cryptographic device, an I / O panel on one rear side with several interfaces and ventilation holes, a dual-power fan bracket and a dual-power plug on the other rear side, a power failure protection box installed at the front end of the dual-power plug, a power cord connected to the lower outer side of the power failure protection box and inserted into a socket via a power plug, a control panel and a display screen on the surface of the power failure protection box, symmetrical mounting threaded holes machined on the rear end of the upper surface of the cryptographic device, a rearward mounting lug on the upper rear side of the power failure protection box and fixed by screws screwed into the mounting threaded holes, raised insert plates corresponding to the positions of the dual-power plugs on the upper and lower inner sides of the power failure protection box, the raised insert plates being aligned and embedded into the dual-power plugs, and a data transmission line on the side of the power failure protection box.

[0007] As a further optimization of this solution, a main board is fixed inside the power failure protection box, and threaded cylinders are provided at the four corners of the outer side of the main board. The cover plate of the power failure protection box is fixed by screwing into the threaded cylinders.

[0008] As a further optimization of this solution, the motherboard is equipped with relays, operational amplifier ICs, and a data interface. The relay pins are respectively connected to the base plate of the upper and lower protruding plug-in plates, the controller, and the current detection resistor. A memory is connected above the controller. The motherboard is connected to the display screen via a display cable and to the control panel via a control line. The data interface is connected to an external data transmission line.

[0009] As a further optimization of this solution, the data transmission line is connected to a USB plug at its outer end, and the USB plug is inserted into the USB port on the I / O panel.

[0010] As a further optimization of this solution, the power failure protection box only covers the outer area of ​​the dual power plugs of the cipher machine.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a power-off protection box structure that can be directly installed on the outer side of the dual power plug of an existing cipher machine. The protruding insert and power cord enable a transfer function, allowing the cipher machine's operating current to pass through the mainboard component of the power-off protection box. When the cipher machine's input current is too high, the current detection resistor detects an abnormality, causing the relay to disconnect the circuit. Alternatively, when the controller detects abnormal temperature data of internal components such as the CPU through the data transmission line, it controls the relay to disconnect the circuit, thus achieving the protection function. Multiple protruding inserts can be designed to accommodate cipher machines with different power supplies. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] To address the issue that existing server cryptographic machines are prone to voltage anomalies after prolonged operation due to the large number of internal components, which can damage these components due to high current, and the risk of damage to individual components when their operating temperature is high;

One end of the rear side of the cryptographic machine 1 is provided with an I / O panel 3, which has several interfaces and heat dissipation holes. The other end of the rear side of the cryptographic machine 1 is provided with a dual power fan bracket 2 and a dual power plug 8. A power failure protection box 4 is installed at the front end of the dual power plug 8. A power cord 5 is connected to the lower end of the outer side of the power failure protection box 4 and is inserted into the socket through a power supply plug 12. A control panel 6 and a display screen 7 are provided on the surface of the power failure protection box 4. Symmetrical mounting threaded holes 9 are machined at the rear end of the upper surface of the cryptographic machine 1. A hanging ear is provided at the upper end of the rear side of the power failure protection box 4 and is fixed by screws 13 into the mounting threaded holes 9. The upper and lower ends of the inner side of the power failure protection box 4 are provided with protruding insert plates 10 corresponding to the position of the dual power plug 8. The protruding insert plates 10 are aligned and embedded into the dual power plug 8. A data transmission line is provided on the side of the power failure protection box 4.

[0021] like Figure 4 As shown, a main board is fixed inside the power failure protection box 4. Threaded cylinders 23 are provided at the four corners of the outer side of the main board. The cover plate of the power failure protection box 4 is fixed by screws into the threaded cylinders 23. The main board is equipped with a relay 16, an operational amplifier IC 14, and a data interface 21. The pins of the relay 16 are respectively connected to the base plate 22 of the upper and lower protruding insert plate 10, the controller 19, and the current detection resistor 15. A memory 20 is connected above the controller 19. The main board is connected to the display screen 7 through the display cable 17 and to the control panel 6 through the control line 18. The data interface 21 is connected to an external data transmission line.

[0022] In practical use, the protruding insert plate 10 of the power failure protection box 4 is aligned and embedded into the dual power plug 8 of the cipher machine 1. The data transmission line is connected to a USB plug 11 at its outer end. The USB plug 11 is inserted into the USB port on the I / O panel 3. The power failure protection box 4 only covers the outer area of ​​the dual power plug 8 of the cipher machine 1. The protruding insert plate 10 is connected to the dual power plug 8. The power cord 5 is connected to the socket through the power supply plug 12 to achieve the conversion function. The working current of the cipher machine 1 passes through the current detection resistor 15 on the motherboard of the power failure protection box 4. When the input working current of the cipher machine 1 is too large, the current detection resistor 15 detects the abnormality and causes the relay 16 to disconnect the circuit. Alternatively, when the controller 19 detects abnormal temperature data of the internal CPU and other components of the cipher machine 1 through the data transmission line, it controls the relay 19 to disconnect the circuit to achieve the protection function. Temperature detection software can be written into the memory 20. The real-time working temperature of the CPU, hard disk and memory modules on the internal motherboard of the cipher machine 1 can be obtained through this software.
