Description

Technical Field

[0001] This utility model relates to the field of train data recording and storage technology, specifically, it demonstrates a train storage server. Background Technology

[0002] Train storage servers are dedicated audio and video data storage devices designed for railway transportation systems. Their core function is to store and manage various key audio and video data generated during train operation in real time, such as dispatch instructions, equipment monitoring data, safety logs, and passenger information system data.

[0003] Train storage servers are primarily used in rail transit systems such as subways and high-speed trains. With the explosive growth of audio and video data on trains, these servers face multiple challenges related to capacity, performance, and reliability. Train storage servers require long-term stable operation to protect the security of stored audio and video data. Environmental factors such as unexpected power outages, train vibrations, and excessively high temperatures can cause hard drive failures. To protect mechanical hard drives from these risks, a series of preventative measures are necessary. Utility Model Content

[0018] This utility model embodiment provides a train storage server to solve the technical problems mentioned in the background art. (See reference...) Figures 1-6As shown. Specifically, it includes a chassis body 1, inside which are installed and fixed several hard drive enclosures 2, a main control PCB board 3, two power modules 4, a supercapacitor module 5, and an interface PCB board 6. The power modules 4 are mainly used to connect external DC power and are electrically connected to the supercapacitor module 5 and the main control PCB board 6. Equipped with two power modules 4, power can still be maintained by the other power module in the event of a single power failure. The dual power redundancy design prevents power interruption through multi-path power supply and hardware redundancy. The main control PCB board 3 is electrically connected to the hard drive enclosures 2, the supercapacitor module 5, and the interface PCB board 6. The function of the supercapacitor module 5 is to provide short-term power when the main power is interrupted, ensuring that cached data is completely written to the flash memory chip, providing power failure protection. See details. Figure 3 The diagram shows the connections between the modules within the system.

[0019] The hard drive extraction enclosure 2 is a standard component. Several hard drive extraction enclosures 2 with a drawer-type structure are embedded into the front of the chassis body 1. The hard drive extraction enclosure 2 has hard drive space inside for removable storage of hard drives. In one embodiment, three hard drive bays 2 are installed inside the chassis body 1. Two of the hard drive bays 2 are arranged vertically on one side of the chassis body 1, while the last hard drive bay 2 is located on the other side of the chassis body 1. That is, the three hard drive bays 2 are installed inside the chassis body 1 in a 2+1 configuration. The supercapacitor module 5 is installed at the rear end of the chassis body 1 and close to the rear of the two hard drive bays. The main control PCB board 3, two power modules 4, and interface PCB board 6 are installed inside the chassis body 1 and above the hard drive bays 2 via a support plate 10. In other words, the support plate 10 is installed horizontally inside the chassis body 1, and the main control PCB board 3, two power modules 4, and interface PCB board 6 are arranged in a certain position and connected by screws on the top surface of the support plate 10. In order to further avoid the design of the support plate affecting the heat dissipation performance of the server, the surface of the support plate can be designed with large-area heat dissipation perforations.

[0020] Installing three hard drive enclosures can increase the server's storage capacity and facilitate quick and easy data identification and management.

[0021] In this implementation, the hard drive extraction enclosure uses the current SAS / SATA hot-swappable hard drive extraction enclosure; the power module uses the current SDL-171C PW.HD060T.001 ultra-thin built-in power board; the main control PCB board uses the current RK3568 core board, which provides stable and reliable electrical connections for other devices and is responsible for controlling various functions of the server; the supercapacitor module uses the current BCC2R7M126YS1030 supercapacitor; the interface PCB board is a non-standard interface board and needs to be combined with the plug-in interfaces and status indicator lights described below. The interface PCB board is mainly used to expand and increase the interface functions of the server.

The hard drive status indicator light indicates whether the hard drive in the hard drive enclosure is working properly, the system status indicator light indicates whether the server is working properly, and the power status indicator light indicates whether the power module is working properly. Different data cables can be connected through the multiple connectors to connect different functional modules, thereby improving data transmission security and stability. The status is indicated by the color of the indicator lights, which facilitates server fault diagnosis.

[0023] In addition, a large area of ​​heat dissipation grilles 9 are provided on the outer shell of the chassis body 1. The heat dissipation grilles 9 are located on the top, bottom and left and right sides of the chassis body 1, and the heat dissipation grilles are used to improve the heat dissipation efficiency of the server.
