Description

Technical Field

[0001] This invention belongs to the field of embedded system technology, specifically relating to a general data offloading system for hardened solid-state drives. Background Technology

[0002] To withstand harsh working environments such as vibration and shock, industrial embedded devices mostly employ ruggedized solid-state drives (SSDs) with shock-resistant mechanical structures. The mechanical and electrical interfaces of these ruggedized SSDs are device-specific, ensuring stable data transmission and retrieval within the device. However, unloading data from ruggedized SSDs presents a challenge: the computer uses a universal interface. Current solutions involve designing a dedicated unloading device for each ruggedized SSD to bridge the gap between the ruggedized and universal interfaces. This method is complex, lacks compatibility across different ruggedized SSDs, and places high demands on the personnel performing the unloading process. Summary of the Invention

[0003] The purpose of this invention is to provide a universal data offloading system for rugged solid-state drives (SSDs) in exploration and other industrial embedded fields, enabling data offloading without dedicated offloading equipment. This addresses the problem that existing technologies require dedicated offloading equipment for rugged SSDs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a universal data offloading system for hardened solid-state drives, the system comprising: A dual-interface switching circuit is connected to the ruggedized SSD main controller and is used to split the data output by the ruggedized SSD main controller into two outputs according to the signal switching. The two outputs are connected to the ruggedized interface and the general interface, respectively. The MOS switching circuit has two different power supply interfaces, which are connected to the ruggedized interface power supply and the general interface power supply, respectively. An adaptive power management system circuit, connected to a MOS switching circuit, is used to switch the output of the dual-interface switching circuit according to the power supply connected to the MOS switching circuit. The secondary power conversion circuit, connected to the adaptive power management system circuit, is used to convert the power introduced by the MOS switching circuit to power the ruggedized solid-state drive.

[0005] The universal data offloading system for ruggedized solid-state drives provided by this invention also has the following technical feature: the ruggedized interface outputs a PCIe 3.0 signal through a ruggedized connector.

[0006] The universal data offloading system for ruggedized solid-state drives provided by this invention also has the following technical features: a PCIe to USB bridge is provided between the dual-interface switching circuit and the universal interface for converting PCIe 3.0 to USB signals and transmitting them; the universal interface outputs USB signals through a universal interface Type-C connector.

A power enable signal is output to the dual-interface switching circuit, which turns on the switching switch of the dual-interface switching circuit and outputs through the general interface.

Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances.

[0019] like Figure 1 As shown, this embodiment of the invention provides a universal data offloading system for ruggedized solid-state drives, the system comprising: A dual-interface switching circuit is connected to the ruggedized SSD main controller and is used to split the data output by the ruggedized SSD main controller into two outputs according to the signal switching. The two outputs are connected to the ruggedized interface and the general interface, respectively. The MOS switching circuit has two different power supply interfaces, which are connected to the ruggedized interface power supply and the general interface power supply, respectively. An adaptive power management system circuit, connected to a MOS switching circuit, is used to switch the output of the dual-interface switching circuit according to the power supply connected to the MOS switching circuit. The secondary power conversion circuit, connected to the adaptive power management system circuit, is used to convert the power introduced by the MOS switching circuit to power the ruggedized solid-state drive.

[0020] The system provided in the above embodiments uses a power management system to control the switching circuit between ruggedized and general interfaces for the physical mechanical and electrical interfaces of ruggedized solid-state drives (SSDs). This solves the problem of requiring dedicated unloading equipment for data offloading of ruggedized SSDs, improving the versatility and maintainability of data offloading for ruggedized SSDs. Furthermore, the ruggedized and general interfaces cover both physical mechanical and electrical interfaces, and can achieve lossless data switching between them according to the interface usage scenario.

[0021] In some embodiments, the ruggedized interface outputs a PCIe 3.0 signal through a ruggedized connector. A PCIe-to-USB bridge is provided between the dual-interface switching circuit and the universal interface for converting and transmitting PCIe 3.0 signals to USB signals. The universal interface outputs a USB signal through a universal interface Type-C connector.

[0022] In the above embodiment, the dual-interface switching circuit includes a signal switching switch for splitting the PCIe 3.0 signal output by the SSD main controller into two paths. One PCIe signal is transmitted to the rugged connector, and the other path converts the PCIe 3.0 signal to a USB signal via a PCIe-to-USB bridge and transmits it to the universal interface Type-C connector. The switching switch is controlled by an adaptive power management system circuit. When the rugged interface is powered by 12V, the switching switch is off, and the SSD's data access is through the rugged connector path. When the universal interface is powered by 5V, the switching switch is on, and the SSD's data access is through the Type-C interface connector path.

[0023] In some embodiments, the ruggedized interface is powered by a 12V power supply, and the general-purpose interface is powered by a 5V power supply.

[0024] In some embodiments, the adaptive power management system circuit is configured as follows: When both 12V and 5V power supplies are input simultaneously, the 5V power supply is selected. A power enable signal is output to the dual-interface switching circuit, which turns on the switching switch of the dual-interface switching circuit and outputs through the general interface. When only 5V power is input, a power enable signal is output to the dual-interface switching circuit, which turns on the dual-interface switching circuit switch and outputs through the general interface. When only 12V power is input, a power enable signal is output to the dual-interface switching circuit, causing the dual-interface switching circuit switch to open and output through the hardened interface.

[0025] In some embodiments, the ruggedized connector is a brush-type ruggedized connector. The brush-type ruggedized connector employs a multi-point contact dynamic compensation principle, effectively distributing the mechanical wear and charge load during the connector's insertion and removal process to hundreds of independent, elastic micro-contact points. Its redundant design ensures low and stable contact resistance, high current carrying capacity, and effective cleaning of the contact surface, compensating for the low reliability of commercial connectors and improving the vibration resistance, reliability, and lifespan of the solid-state drive.

[0026] In some embodiments, the ruggedized solid-state drive main controller is a PCIe 3.0 x4 controller. The PCIe 3.0 x4 controller is a STAR controller, featuring a PCIe 3.0 x4 interface, backward compatible with PCIe 2.0 and PCIe 1.0, with lane backward compatible with x2 and x1, supporting the NVMe protocol, and a maximum transmission rate of 32Gbps.

[0027] In some embodiments, the secondary power conversion circuit includes a power-down protection sub-circuit and a hot-swap protection sub-circuit. The power-down protection sub-circuit is used for capacitor backup energy storage and discharge after power failure when the power is lost due to the reinforcement power supply interface or the simultaneous power supply of two power supply interfaces. The hot-swap protection sub-circuit is used for overvoltage and overcurrent protection when the two power supply interfaces are simultaneously powered, and sets reasonable voltage and current limiting points.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
