Description

Technical Field

[0001] This utility model relates to the field of hard disk technology, and in particular to a novel solid-state hard disk with UWB positioning. Background Technology

[0002] Data storage security is paramount. While there are many encryption methods for hard drives, there are even more decryption methods. The most effective security management is to monitor the real-time location of the data storage medium (hard drive) and keep important storage disks within a safe range to prevent leakage. Currently, hard drives are mainly used for data storage, but they lack location protection for the hard drive itself, making them prone to loss. Confidential data can be decrypted, causing incalculable losses to individuals, businesses, and even national security. Therefore, we propose a new type of solid-state drive with UWB positioning. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. Current hard drives are mainly used for data storage, but they lack positioning protection for the hard drive itself, making them prone to loss. Confidential data can be decrypted, causing incalculable losses to individuals, businesses, and even national security.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel solid-state drive (SSD) with UWB positioning includes an SSD controller chip, a FLASH memory chip, a UWB chip, a power supply circuit, a battery, an antenna, and an alarm buzzer. The SSD controller chip, FLASH memory chip, UWB chip, power supply circuit, battery, antenna, and alarm buzzer are integrated on the SSD PCB motherboard. The SSD controller chip is electrically connected to the UWB chip and is used to allocate data load on the FLASH memory chip for data transfer. The battery powers the UWB chip, and the UWB chip is electrically connected to the antenna. The power supply circuit is electrically connected to the SSD controller chip, FLASH memory chip, UWB chip, and battery.

[0006] Furthermore, the solid-state drive PCB motherboard provides electrical connections and support for communication and data transmission between the solid-state drive controller chip, FLASH flash memory chip, UWB chip, power supply circuit, battery, and antenna.

[0007] Furthermore, the alarm buzzer is electrically connected to the UWB chip.

[0008] Furthermore, the UWB chip serves as a positioning tag, wirelessly connecting to multiple UWB positioning base stations, and the UWB positioning base stations are connected to a data monitoring terminal via Ethernet cable, Wi-Fi, 4G, or 5G.

[0009] Furthermore, the UWB chip transmits radio waves to multiple UWB positioning base stations for reception, and ranging can be achieved through the two-way flight time of the radio waves.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] With a built-in UWB chip, the solid-state drive (SSD) has an effective positioning radius of several hundred meters. Utilizing UWB (Ultra Wide Band) technology, it can monitor and locate multiple storage drives in real time. The real-time location of the drives can be viewed on a monitoring host computer or mobile phone. A pre-defined safe zone can be established, and when a drive moves outside the designated safe zone, an alarm sounds on the drive, and the monitoring host or mobile phone receives an alarm notification, allowing the user to know in advance which drive is alarming and displaying the real-time location of the alarming drive. This new UWB-positioning SSD is ideal for data storage in technically sensitive laboratories and offices, government offices, and secure data centers. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Example 1, as Figure 1 As shown, this utility model provides a technical solution: a novel solid-state drive (SSD) with UWB positioning, comprising an SSD controller chip 1, a FLASH flash memory chip 2, a UWB chip 3, a power supply circuit 4, a battery 5, an antenna 6, and an alarm buzzer 7. The SSD controller chip 1, FLASH flash memory chip 2, UWB chip 3, power supply circuit 4, battery 5, antenna 6, and alarm buzzer 7 are integrated on the SSD PCB motherboard. The SSD controller chip 1 is electrically connected to the UWB chip 3 and is used to allocate the data load on the FLASH flash memory chip 2 for data transfer. The battery 5 supplies power to the UWB chip 3. The UWB chip 3 is electrically connected to the antenna 6. The power supply circuit 4 is electrically connected to the SSD controller chip 1, FLASH flash memory chip 2, UWB chip 3, and battery 5.

[0023] It should be added that the solid-state drive PCB motherboard provides electrical connections and support for communication and data transmission between the solid-state drive controller chip 1, FLASH flash memory chip 2, UWB chip 3, power circuit 4, battery 5, and antenna 6.

[0024] The alarm buzzer 7 is electrically connected to the UWB chip 3.

[0025] The UWB chip 3 acts as a positioning tag, wirelessly connecting to multiple UWB positioning base stations. The UWB positioning base stations are connected to the data monitoring terminal via Ethernet cable, Wi-Fi, 4G, or 5G.

[0026] UWB (Ultra Wide Band) technology is a wireless carrier communication technology that does not use a sinusoidal carrier. Instead, it transmits data via nanosecond-level non-sinusoidal extremely narrow pulses, thus occupying a very wide spectrum, with a bandwidth generally exceeding 500MHz. This allows for high-precision distance measurement, with accuracy down to the centimeter level. Its operating frequency band is 3.1-10.6GHz.

[0027] Through the above embodiments, such as Figure 2 As shown, the UWB positioning principle consists of multiple positioning base stations and positioning tags. The locations of the UWB positioning base stations are known and they are installed in the corners of designated areas, specifically in the four corners of the office area. The positioning tags are installed on mobile devices.

[0028] First, the UWB chip emits radio waves. Ranging is achieved through the two-way time of flight (TOF) of these radio waves, as follows:

[0029] Device A initiates a ranging request, and device B, as a responder, responds and listens to the radio messages initiated by device A. A sends a radio message to B and records its transmission timestamp t1. After receiving the message, B sends a reply to A after a specific delay treplyB. When A receives the reply and records a reception timestamp t2, after another specific delay treplayA sends a radio message to B and records its transmission timestamp t3. Finally, B receives the message and records its timestamp t4.

[0030] Since the round-trip time is known, we can obtain:

[0031] 1)troundA=treplyB+2TOF=t2-t1;

[0032] 2)troundB=treplyA+2TOF=t4-t0;

[0033] The time of flight of the signal is: TOF = (troundA - treplyB + troundB - treplyA) / 4;

[0034] If the speed of radio waves is v, then the distance between device A and device B is L = TOF * v.

[0035] Based on the above ranging principle, such as Figure 3As shown, when the tag measures distances with multiple base stations, the real-time distance between the tag and multiple base stations can be obtained. Draw a circle with the base station as the center and the distance from the base station to the tag as the radius. The intersection of the three circles is the tag's current position. In actual applications, due to ranging errors, the three circles are unlikely to intersect at a single point, but will only intersect in a region. This is the positioning error. The positioning accuracy of this UWB can be achieved at the centimeter level.

[0036] Furthermore, since the base station coordinates are known, the coordinates can be calculated using the equation of a circle, as shown in the formula below. Figure 4 As shown;

[0037] The working principle of this utility model is as follows: The UWB positioning base station can access the Internet. The UWB chip 3 transmits the real-time location of the SSD solid-state drive to the computer server or mobile phone for data monitoring. An electronic fence is pre-defined for the safe area. Once the SSD hard drive located by UWB is taken out of the safe area, the alarm buzzer 7 on the hard drive will sound an alarm. At the same time, the positioning software system on the monitoring computer will also issue an alarm prompt.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
