[0038] The embodiment of the present application provides a hard disk, comprising: a hard disk motherboard and a positioning label integrated on the hard disk motherboard; the positioning label is used to accurately position the hard disk in different environments (such as indoor environments or outdoor environments, etc.), wherein, Figure 1 As shown, the positioning tag includes:

[0039] a first positioning module having a positioning function in an outdoor environment; the first positioning module may also be referred to as a first positioning device / apparatus / assembly / component / device / (integrated) circuit, or an outdoor positioning module / apparatus / apparatus / assembly / component / device / (integrated) circuit, etc.; the outdoor environment may also be referred to as an outdoor area, i.e., an area outside a building;

[0040] The second positioning module has a positioning function in an indoor environment; the second positioning module may also be referred to as a second positioning device / apparatus component / component / device / (integrated) circuit, or an indoor positioning module / apparatus / apparatus / component / component / device / (integrated) circuit, etc.; the indoor environment may also be referred to as an indoor area, i.e., an area within a building;

[0041] The controller module is electrically connected to the first positioning module and the second positioning module respectively, and is used to receive the outdoor positioning signal of the first positioning module and / or the indoor positioning signal of the second positioning module, and send the received outdoor positioning signal and / or the indoor positioning signal to an external device; here, the controller module can be a controller of a hard disk that multiplexes the positioning tag, or it can be a controller set on the motherboard of the hard disk specifically for positioning processing.

[0042] Here, the controller module sends the received outdoor positioning signal and / or indoor positioning signal to an external device (such as a cloud device, a server device, a mobile terminal, etc.), which can facilitate the staff to promptly learn the real-time location of the hard disk.

[0043] In addition, in the positioning tag of the embodiment of the present application, by setting the first positioning module and the second positioning module, the intelligent positioning switching of the hard disk indoors and outdoors can be realized, and seamless positioning can be achieved. Compared with the device that only sets the outdoor positioning module, the hard disk can be accurately positioned in the indoor environment. Compared with the device that only sets the indoor positioning module, the hard disk can be accurately positioned in the outdoor environment, thereby realizing accurate positioning / position tracking of the hard disk in any environment.

[0044] The hard disk of the embodiment of the present application is structured such that a positioning tag is integrated on the hard disk motherboard, which can realize the positioning / tracking of the hard disk. Specifically, the positioning tag includes: a first positioning module, which has the function of positioning in an outdoor environment; a second positioning module, which has the function of positioning in an indoor environment; a controller module, which is electrically connected to the first positioning module and the second positioning module, respectively, for receiving the outdoor positioning signal of the first positioning module and / or the indoor positioning signal of the second positioning module, and sending the received outdoor positioning signal and / or the indoor positioning signal to an external device. In this way, when the hard disk is located outdoors, the hard disk is positioned using the first positioning tag, and when the hard disk is located indoors, the hard disk is positioned using the second positioning tag, thereby realizing accurate positioning of the hard disk in any environment, and transmitting the positioning information to the external device in real time, so that the user can understand the location of the hard disk at any time, thereby further reducing the risk of leakage of data stored in the hard disk due to loss or theft of the hard disk, and improving the security of data storage.

[0045] As a specific implementation, the first positioning module includes at least one of the following:

[0046] Beidou satellite positioning module;

[0047] LoRa positioning module; LoRa positioning module is a low-power wide area network-based geolocation technology that mainly uses arrival time difference to achieve accurate location tracking. This technology utilizes the LoRaWAN network to transmit data packets between the terminal node and the server and measure the time difference between these data packets reaching the server from different base stations or gateways to calculate the location of the target object;

[0048] ZigBee positioning module; ZigBee positioning module is suitable for applications with short distance, low traffic, and low power. Specifically, the ZigBee positioning module can use the Received Signal Strength Indication (RSSI) ranging method to achieve positioning. More specifically, it can use the Pythagorean theorem of triangles and the conversion of RSSI and distance to achieve positioning.

[0049] Global Positioning System (GPS) positioning module.

[0050] The above-mentioned Beidou satellite positioning module, LoRa positioning module, ZigBee positioning module and GPS positioning module are modules that have the function of accurately positioning the target (the hard disk in the embodiment of the present application) in an outdoor area.

[0051] As another specific implementation, the second positioning module includes at least one of the following:

[0052] Ultra-Wideband (UWB) positioning module; Here, UWB is a carrier-free communication technology that can transmit data using non-sinusoidal narrow pulses in the nanosecond to picosecond range. By transmitting extremely low-power signals over a wider spectrum, UWB technology can achieve data transmission rates of hundreds of Mbit / s to several Gbit / s within a range of about 10 meters. It has the advantages of strong anti-interference performance, high transmission rate, large system capacity, very low transmission power, and can greatly extend the system power supply working time. Among them, the UWB positioning module 13 and the UWB base station 2 use the time of flight (TOF) ranging method for ranging, that is, the UWB positioning module transmits a pulse radio for a first time, and multiple UWB base stations receive the pulse radio for a second time, and then by analyzing and calculating the time difference between the first time and the second time, the flight time of the pulse radio is obtained, and then the distance from the UWB positioning module to each UWB base station is calculated, and then the indoor positioning coordinate information of the UWB positioning module is determined;

[0053] Bluetooth positioning module;

[0054] Wireless network WIFI positioning module.

[0055] Furthermore, as an optional implementation, the hard disk further includes a housing, and the hard disk mainboard, the first positioning module, the second positioning module and the controller module are located in the housing.

[0056] Furthermore, as an optional implementation, the positioning tag further includes:

[0057] A first antenna interface, embedded in the housing and connected to the first positioning module; for example, the first antenna interface may be a Sub Miniature Version A (SMA) interface, wherein a standard SMA interface has an external thread and a hole at one end and an internal thread and a pin at the other end; the first antenna interface is connected to the first positioning module via an IPX-to-SMA cable, wherein IPX-to-SMA cables are commonly used in fields such as wireless communications and radio frequency identification to ensure that devices with different interfaces can connect and communicate normally;

[0058] A first antenna is located outside the housing and connected to the first antenna interface. The first antenna is arranged outside the housing and even extends to the outside of the housing of the host computer where the hard disk is located, so as to prevent the first antenna from being unable to normally receive and transmit signals due to shielding by the housing.

[0059] A second antenna interface is embedded in the housing and connected to the second positioning module. Here, the second antenna interface can be the same as the first antenna interface, both using an SMA interface. The second antenna interface and the second positioning module are also connected via an IPX to SMA cable.

[0060] The second antenna is located outside the shell and is connected to the second antenna interface. Similarly, the second antenna can even extend to the outside of the shell of the host machine where the hard disk is located to avoid the second antenna being unable to receive and transmit signals normally due to shielding of the shell.

[0061] Here, it should be noted that when the controller module sends the outdoor positioning information to an external device, it is specifically sent to the corresponding satellite or base station through the first positioning module, the first antenna interface and the first antenna, so that the satellite or base station sends the outdoor positioning information to the external device; similarly, it should be noted that when the controller module sends the indoor positioning information to an external device, it is specifically sent to the corresponding satellite, base station or gateway through the second positioning module, the second antenna interface and the second antenna, so that the satellite, base station or gateway sends the outdoor positioning information to the external device.

[0062] Of course, further, as an optional implementation, such as Figure 1 As shown, the hard disk also includes: a power supply data interface embedded in the shell, wherein the power supply data interface is electrically connected to the first positioning module, the second positioning module and the controller module (not shown in the figure) to supply power to the first positioning module, the second positioning module and the controller module. It should be noted that at this time, the hard disk is located in its host machine, and the host machine supplies power to the first positioning module, the second positioning module and the controller module through the power supply data interface. Wherein, the hard disk is specifically electrically connected through a parallel port (Integrated Drive Electronics, IDE), a serial port (Serial Advanced Technology Attachment, SATA), a small computer system interface (Small Computer System Interface, SCSI), a serial connection small computer system interface (Serial Attached Small Computer System Interface, SAS) and a fiber channel interface. In other words, the power supply data interface is an IDE, SATA, SCSI, SAS or fiber channel interface.

[0063] In addition, if Figure 1 As shown, the power supply data interface is also in communication with the controller module ( Figure 1 In this way, the controller module can communicate with its host machine / transmit and receive data through the power supply data interface. Therefore, the controller module can send the outdoor positioning information and / or the indoor positioning information to the host machine through the power supply data interface, so that the host machine can send it to the external device.

[0064] As another optional implementation, the hard disk may further include a communication module ( Figure 1 (not shown), the communication module is connected to the controller module, so that the controller module can send the outdoor positioning information and / or the indoor positioning information to the external device via the communication module. Transmitting the outdoor positioning information and / or the indoor positioning information via the communication module can improve data transmission efficiency and achieve real-time data transmission.

[0065] Furthermore, as an optional implementation, Figure 1 As shown, the hard disk further includes:

[0066] A power supply module includes a rechargeable battery, which is electrically connected to the first positioning module, the second positioning module and the controller module respectively, and is used to provide operating voltage for the first positioning module, the second positioning module and the controller module.

[0067] It should be noted here that, as an example, the nominal voltage of the rechargeable battery is 3.7V, that is, the power module can provide a 3.7V operating voltage for the first positioning module, the second positioning module and the controller module. In this way, when the hard disk is independent of its host machine, the power module can provide an operating voltage for each of the above modules to ensure that outdoor positioning information and / or indoor positioning information can still be transmitted in a short time, so that the user can understand the location of the hard disk in a timely manner and avoid the data in the hard disk from being illegally stolen.

[0068] Of course, when the hard disk includes a power supply data interface, the power module can also be electrically connected to the power supply data interface to enable the AC power or host machine to charge the rechargeable battery through the power supply data interface, so that when the hard disk is independent of the host machine, the rechargeable battery can provide working voltage for each module on the hard disk.

[0069] As an optional implementation, the hard disk further includes: a storage module for storing data within the life cycle of the hard disk, wherein the storage module is electrically connected to the controller module. In this way, the controller module can control the storage module, such as controlling the storage module to erase the data stored therein. For example, when the controller module receives a message from an external device indicating that the hard disk is outside a pre-set target area (legal area), the controller module can send a data erase instruction to the storage module to erase the data in the storage module to avoid data leakage. In addition, specifically, the storage module and the controller module are electrically connected via a NAND Flash interface.

[0070] As a specific example, the hard disk of the embodiment of the present application includes a storage module for storing data within the life cycle of the hard disk, a power supply data interface connected to the host, a power module and a positioning tag, wherein the power supply data interface is connected to the power module, and the host or the mains electricity charges the rechargeable battery in the power module through the power supply data interface, and the rechargeable battery is used to provide working voltage for each module in the storage module and the positioning tag after the hard disk and the host are powered off. Specifically, the positioning tag includes a controller module, a first positioning device (including a first positioning module, a first antenna interface and a first antenna connected in sequence) and a second positioning device (including a second positioning module, a second antenna interface and a second antenna connected in sequence) connected to the controller module respectively; wherein the controller module can communicate with an external device through the first positioning device / second positioning device, and can also communicate with an external device through the power supply data interface and the host; the controller can also manage the storage module, such as destroying the data in the storage module. In this way, the hard disk can have a positioning function in different environments, realizing seamless positioning indoors and outdoors, so that the data stored in the hard disk can be processed based on the positioning results to avoid data leakage.

[0071] In addition, as a specific example, the first positioning module is electrically connected to the controller module via a universal asynchronous receiver / transmitter (UART);

[0072] Alternatively, the second positioning module is electrically connected to the controller module via a serial peripheral interface (SPI).

[0073] Below, the positioning process of the hard disk in the embodiment of the present application is described by taking the first positioning module as a Beidou satellite positioning module and the second positioning module as a UWB positioning module as an example:

[0074] When the hard drive is in an outdoor environment, the Beidou satellite positioning module in the positioning tag inside the hard drive receives signals from Beidou satellites and transmits the signals to the controller module. The controller module parses the Beidou satellite signals, calculates the hard drive's outdoor location coordinate data (corresponding to the aforementioned outdoor positioning information), and transmits the data to the data center (corresponding to the aforementioned external device) via a Beidou short message (corresponding to the transmission based on the first positioning module, the first antenna interface, and the first antenna).

[0075] When the hard drive enters an indoor environment, the UWB positioning module in the positioning tag begins to operate. The UWB positioning module transmits a pulsed radio signal, which is received by the indoor UWB base station and returns a feedback signal. Based on the feedback signal from the UWB base station, the controller module calculates the indoor location coordinate data of the hard drive (corresponding to the aforementioned indoor positioning information) and transmits it to the data center (corresponding to the aforementioned external device) via the indoor UWB gateway (corresponding to the transmission based on the second positioning module, the second antenna interface, and the second antenna).

[0076] When transmitting outdoor positioning information and / or indoor positioning information to an external device, the controller module also transmits real-time time information and the device's unique serial number (provided by the hard disk's security chip to prevent the serial number from being maliciously tampered with).

[0077] Furthermore, after transmitting the indoor positioning information and / or outdoor positioning information to the external device, the controller module may also receive a control instruction (such as a data destruction instruction) fed back by the external device, and transmit a large current to the storage module based on the control instruction to destroy the data in the storage module by damaging the storage module, or transmit a data erasure instruction to the storage module based on the control instruction to trigger the storage module to erase the data stored therein. The control instruction may be an instruction generated by the external device based on the received outdoor positioning information and / or indoor positioning information. For example, when the external device determines that the hard disk is located outside a pre-set target area (i.e., the hard disk is located in an illegal area) based on the outdoor positioning information and / or indoor positioning information, the control instruction is generated. The target area is related to the stage of the hard disk (distribution stage, use stage, maintenance stage, and destruction stage). The target area may also be referred to as an electronic fence.

[0078] Here, it should be noted that the controller module can be directly electrically connected to the storage module, and can also be connected through a module for triggering data destruction (such as a circuit with a current amplification function or a component with an instruction forwarding function).

[0079] In addition, when the external device receives both outdoor positioning information and indoor positioning information (i.e., the hard disk is located in an environment that switches between indoors and outdoors), the external device can determine the final positioning information of the hard disk based on data fusion of the outdoor positioning information and the indoor positioning information (such as directly determining by weighting or averaging, or filtering relatively accurate location information based on the signal strength of the outdoor positioning information and the indoor positioning information. For example, if the signal strengths of both are higher than a preset strength, the final positioning information can be determined by weighting or averaging. If the signal strength of only one is higher than the preset strength, the information is determined as the final positioning information of the hard disk), thereby improving positioning accuracy; and further determining whether the hard disk is located in the target area based on the final positioning information. If not, the control instruction is generated. Of course, the above-mentioned functions of the external device can also be implemented by the controller module, that is, the controller module determines whether the hard disk is located in the target area based on the received outdoor positioning information and / or indoor positioning information. When it is determined that the hard disk is not located in the target area, the storage module is triggered to destroy the data stored therein, so as to achieve security protection of data at all stages of the hard disk's life cycle and avoid data leakage.

[0080] The hard drive provided in the embodiments of this application integrates a Beidou satellite positioning module (first positioning module) and a UWB positioning module (second positioning module) into the hard drive's positioning tag, utilizing Beidou satellite signals for high-precision outdoor positioning while simultaneously utilizing UWB signals for high-precision indoor positioning. By intelligently switching and fusing the two positioning signals, seamless positioning of the hard drive is achieved both indoors and outdoors, ultimately enabling precise location tracking of the hard drive in any environment. This meets the requirements for high-precision positioning and monitoring of hard drives in complex environments, thereby ensuring the security of the data stored on the hard drive throughout its lifecycle.

[0081] The embodiment of the present application also provides an electronic device, such as Figure 2 As shown, it includes a device host and the hard disk as described above, wherein the device host is connected to the aforementioned power supply data interface and storage module to achieve electrical connection and communication between the device host and the hard disk. The electronic device can be a device widely used in computing, communication, network boundaries, etc. The hard disk with positioning function as described above is installed on the electronic device. On the one hand, it can achieve real-time location supervision of data processing and data communication equipment. On the other hand, based on the location supervision of the entire life cycle of hard disk distribution, use, maintenance and destruction, it can ensure the data traceability and audit compliance of the information system constructed by these hard disks, ultimately ensuring the security of data throughout its life cycle, improving the efficiency and accuracy of asset management, and reducing operating costs.

[0082] The hard disk and electronic device of the embodiment of the present application, firstly, can realize seamless connection of indoor and outdoor positioning based on the positioning function of the Beidou satellite positioning module and the UWB positioning module. This avoids the problem of positioning interruption or increased error when switching between indoor and outdoor with the traditional positioning method; secondly, when the hard disk is indoors, the hard disk position data is transmitted back to the service platform in real time via the UWB gateway; when the hard disk is outdoors, the hard disk position data is transmitted back to the service platform in real time via the Beidou short message. Thirdly, the system can flexibly deploy UWB base stations according to actual needs to meet the positioning needs in different scenarios. At the same time, this method also supports integration and expansion with other positioning technologies.

[0083] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0084] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
