Description

Technical Field

[0001] This utility model relates to the field of storage host system technology, and in particular to a novel train video storage host system. Background Technology

[0002] With the increasing amount of onboard video data, train audio and video storage devices play a particularly important role, and train video monitoring systems play a vital role in train operation.

[0003] Traditional onboard video storage devices mostly use x86 processors and Windows file systems, with 100 Mbps Ethernet input for video data. However, such devices are not suitable for high-speed trains and cannot meet the real-time data storage requirements during train operation.

[0004] Specifically, this not only presents the problem of high power consumption, but also the risk of video data loss after power failure. Furthermore, the development and maintenance costs are very high, which further reduces the reliability and security of the stored data in current locomotive video storage devices. These devices suffer from technical defects such as high product costs, frequent loss of video data after power failure, and low communication speed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a new type of train video storage host system, which aims to solve the technical problems of storage capacity and transmission speed in the prior art.

[0006] To achieve the above objectives, the present invention employs the following:

[0007] This utility model provides a novel train video storage host system, including a main control module, a video storage module, a first communication module, a second communication module, a power supply, and a hard disk. The power supply is electrically connected to the main control module. The first communication module is bidirectionally connected to the main control module through a first network interface. The second communication module is bidirectionally connected to the main control module through a second network interface. The main control module is electrically connected to the video storage module through a high-speed transmission interface. The hard disk is electrically connected to the main control module through a SATA port.

[0008] Furthermore, the main control module uses the RK3568 core board, which divides the four wires of the USB3OTG interface of the RK3568 core board into two groups of signals. One group is used as a differential transmit signal and the other group is used as a differential receive signal. The differential transmit signal and differential receive signal are respectively connected to the transmit port and receive port of the SATA port through a capacitor. All other pins of the SATA port are grounded.

[0009] Furthermore, the main control module is equipped with an electronic lock. This lock is used to output a hard drive protection signal when the electronic lock is open, ensuring the integrity of the video information and preventing data from being downloaded or transmitted in hard drive protection mode.

[0010] Furthermore, the main control module is equipped with a power-loss protection module. This module provides backup power in the event of a power drop or failure, ensuring data security.

[0011] Furthermore, the main control module is equipped with a storage device reset module. This module is used to detect whether the main control module has undergone a restart operation; if so, it drives the power supply of the video storage module to reset.

[0012] Furthermore, a log recording module is provided on the main control module. The log recording module is used to store event information and fault logs related to the video storage module.

[0013] Furthermore, the first network interface uses an M12 interface, and the second network interface uses a DB9 interface. Utilizing the gigabit network interface to support gigabit Ethernet significantly improves video data transmission speed.

[0014] Furthermore, it also includes a USB interface, which is electrically connected to the main control module. The USB interface uses a USB 3.0 interface to connect to the main control module and is used to transmit online downloaded video information.

[0015] Compared with existing technologies, the advantages of this utility model are: it adopts a low-power microprocessor to reduce overall power consumption; it supports Gigabit Ethernet and USB 3.0 interfaces, which greatly improves the video data transmission speed; it is designed with online hard drive detection and power failure delay functions to ensure data integrity; and it has a storage capacity of up to 12TB and supports RAID0, RAID1, RAID5 and other configurations to ensure data security.

Detailed Implementation

[0025] To more clearly illustrate this utility model, the following description, in conjunction with preferred embodiments, further clarifies the invention. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Please see Figure 1 As shown in the figure. This utility model embodiment proposes a novel train video storage host system, including a main control module 1, a video storage module 2, a first communication module 3, a second communication module 4, a power supply 5, and a hard disk 6.

[0028] Power supply 5 is electrically connected to main control module 1 to supply power to the processor. First communication module 3 is bidirectionally connected to main control module 1 through first network interface 31. Second communication module 4 is bidirectionally connected to main control module 1 through second network interface 41. Main control module 1 is electrically connected to video storage module 2 through high-speed transmission interface 21. Hard disk 6 is electrically connected to main control module 1 through SATA port 61.

[0029] The main control module uses the RK3568 core board processor, which is responsible for receiving video information and performing parsing, compression and encoding processing. Specifically, it receives video information through the first network interface, parses and encodes the video information, and then sends the processed video information to the video storage module through the high-speed data transmission interface (i.e. SATA interface).

[0030] The system uses the RK3568 as its core and makes comprehensive use of the core board's resources. Figure 2 The diagram shows the external pins of the RK3568 core board, which reuses its USB3OTG interface as a SATA port. The USB3OTG interface has two application modes: HOST mode and DEVICE mode. Its operating mode is mainly selected by the core board pin USB3_OTG0_ID. When this pin is pulled low, the master device (core processor) is in HOST mode and the slave device (hard drive) is in DEVICE mode. When the pin is floating, it is connected to a high level by default, and the master device (core processor) is in DEVICE mode and the slave device (hard drive) is in HOST mode. When the core board is used as a slave device, the USB3_OTG0_VBUSDET pin can be used to determine whether the core board is connected to a master device.

[0031] The connection method between hard drive 6 and SATA port 61 is as follows: Figure 3 As shown, the RK3568 core board's USB3OTG interface is reused as a SATA port, with the core processor and hard drive acting as master and slave devices to each other. The four wires of the USB3OTG interface are divided into two sets of signals: one set is differential transmit signals (HTXP, HTXN), and the other set is differential receive signals (HRXP, HRXN). They are connected to the transmit port (DTXP, DTXN) and receive port (DRXP, DRXN) of the SATA port respectively through a 10nF capacitor. All other pins of the SATA port are connected to GND.

[0032] This host system uses the RK3568 processor as its core and is equipped with a variety of interfaces, including audio / video interfaces, SATA ports, USB ports, and gigabit Ethernet ports. Figure 4 As shown, network videos and local videos are stored on the hard drive via the SATA port. The hard drive capacity is available in 10TB and 12TB versions. The hard drive is ultimately placed in a 2U chassis, one on each side.

[0033] The first communication module 3 receives real-time video information during train operation through the first network interface 31 and transmits it to the main control module 1. Specifically, the first communication module is connected to the Ethernet switching board in the train video monitoring system to obtain the real-time video information transmitted during train operation and transmit this video information to the main control module through the first network interface, which is a gigabit network interface, such as an M12 interface. The second communication module 4 is connected to the main control module 1 through the second network interface 41 and is used to transmit real-time online download video information, which is a DB9 interface.

[0034] In this embodiment, both the first communication module 3 and the second communication module 4 are used to implement network communication. Specifically, an existing RTL8211F-CG Gigabit Ethernet transceiver can be selected.

[0035] Video storage module 2 is used to store processed video information. It mainly acquires and stores video information through a high-speed data transmission interface. In this embodiment, the video storage module consists of two parts: one part is in the memory integrated into the RK3568 processor, and the other part is in the hard disk.

[0036] The main control module 1 also has a power failure protection module 11, a storage device reset module 12, and a log recording module 13. The hard drive also has an electronic lock, which is connected to the main control module. When the electronic lock is in the open state, it outputs a hard drive protection signal. After receiving the hard drive protection signal, the main control module enters the hard drive protection mode to drive the video storage module to lock the stored video information.

[0037] like Figure 5 The diagram shown is a circuit diagram of the power failure protection module 11, which provides backup power to ensure data security when the input power drops or fails.

[0038] like Figure 6 The diagram shows the circuit diagram of the storage device reset module 12, which is used to detect whether the main control module has restarted. If it does, it drives the power reset of the video storage module.

[0039] like Figure 7 The diagram shown is a circuit diagram of the log recording module 13, which is used to store event information and fault logs for the video storage module.

[0040] The host system in this embodiment also includes a USB interface 7, which is electrically connected to the main control module 1. The USB interface adopts a USB 3.0 interface and is connected to the main control module for transmitting online downloaded video information.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
