[0056] a data destruction module connected to the storage module and configured to destroy data in the storage module; where destroying data in the storage module means making the data in the storage module unusable, such as making it impossible to read the data in the storage module;

In this way, the controller module can control the reading and writing of data in the storage module.

[0058] Among them, the first positioning module transmits the outdoor positioning information to the controller module, and / or the second positioning module transmits the indoor positioning information to the controller module, the controller module transmits the outdoor positioning information and / or the indoor positioning information to the communication module, and the communication module transmits the outdoor positioning information and / or the indoor positioning information to the external device; in simple terms, the first positioning module sends the outdoor positioning information to the controller module, the second positioning module sends the indoor positioning information to the controller module, the controller module sends the received outdoor positioning information and / or indoor positioning information to the external device using the communication module, so that the external device determines whether the electronic device is located in a reasonable / legal area based on the received outdoor positioning information and / or indoor positioning information; the specific determination process can be a position comparison process, comparing the outdoor positioning information / indoor positioning information with a pre-stored target area (reasonable / legal area);

[0059] The controller module sends a first control instruction representing the damaged data to the data damage module, and the data damage module damages the data in the storage module. Here, the first control instruction is generated and transmitted by the aforementioned external device, and the transmission process of the first control instruction will be described later.

In the electronic device of the embodiment of the present application, the positioning of the electronic device can be achieved through signal transmission between the first positioning module / second positioning module, the controller module, the data destruction module, the storage module, the communication module and the external device, and when the external device determines that the electronic device is located in an illegal area (an area outside the preset target area) based on the positioning information (outdoor positioning information / indoor positioning information), the control instruction is transmitted to the controller module, which can trigger the controller module to transmit a signal to the data destruction module to destroy the data in the storage module, thereby avoiding leakage of data in the storage module and ensuring data security.

[0061] As an optional implementation, the communication module includes any one of the following:

[0062] Category 1 communication module: Category 1 technology is a modulation and coding technology of Long Term Evolution (LTE) technology. It can provide relatively high data transmission rates, making electronic devices more real-time, while also being low power and low-cost. This enables real-time transmission of electronic device data (especially positioning-related data), improving the real-time performance of electronic devices and preventing the loss of stored data in electronic devices due to positioning delays.

[0063] LTE communication module;

[0064] 5th Generation Mobile Communication Technology (5G) communication module;

[0065] Narrow Band Internet of Things (NB-IOT) communication module.

[0066] That is to say, the communication module can be any module that can realize cellular (Internet of Things) network communication, wherein the communication module is preferably a Cat.1 communication module, so that remote transmission and real-time processing of data can be realized, thereby improving the real-time performance of electronic equipment.

[0067] As an optional implementation, the first positioning module includes at least one of the following:

[0068] Beidou satellite positioning module; with outdoor high-precision positioning capability;

[0069] 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 uses 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;

[0070] 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.

[0071] Global Positioning System (GPS) positioning module;

[0072] 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 a target (the electronic device of the embodiment of the present application) in an outdoor area.

[0073] Alternatively, the second positioning module includes at least one of the following:

[0074] Ultra-Wideband (UWB) positioning module; Here, UWB is a carrier-free communication technology that can achieve centimeter-level positioning accuracy in indoor environments. Specifically, it can use non-sinusoidal narrow pulses in the nanosecond to picosecond range to transmit data. 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 and very low transmission power, which 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;

[0075] Bluetooth positioning module;

[0076] Wireless network WIFI positioning module.

[0077] The UWB positioning module, Bluetooth positioning module, and Wi-Fi positioning module are modules that can accurately locate the target (the electronic device in the embodiment of the present application) in indoor areas. The base station corresponding to the second positioning module can be flexibly deployed according to actual needs to meet the positioning requirements in different scenarios.

[0078] In the above optional implementation, by setting the first positioning module to at least one of the Beidou satellite positioning module, LoRa positioning module, ZigBee positioning module and GPS positioning module, and setting the second positioning module to at least one of the UWB positioning module, Bluetooth positioning module and WIFI positioning module, by intelligently switching and fusing the two positioning signals, it is possible to accurately locate the electronic device whether it is located indoors or outdoors, thereby achieving seamless connection between indoor and outdoor electronic devices, and ultimately achieving accurate positioning of electronic devices located in complex environments, avoiding the problem of increased positioning terminals or errors when switching between indoor and outdoor in traditional positioning methods. In addition, the positioning method in the embodiment of the present application can also be integrated and expanded with other positioning technologies to improve positioning accuracy.

[0079] Furthermore, as an optional implementation, the electronic device further includes:

[0080] An alarm module is embedded in the housing of the electronic device, wherein the alarm module is connected to the controller module. Here, the control module can trigger the alarm module to alarm or stop the alarm; specifically, the external device can determine whether it is necessary to control the electronic device to alarm based on the outdoor positioning information and / or indoor positioning information sent by the communication module. If an alarm is required, the external device sends an alarm instruction to the communication module, and the communication module transmits the alarm instruction to the controller module. The controller module triggers the alarm module to alarm based on the alarm instruction. Specifically, for example, the controller module transmits an electrical signal (such as a high level) to the alarm module to trigger the alarm module to start; if the alarm needs to be stopped, the external device sends a stop alarm instruction to the communication module, and the communication module transmits the stop alarm instruction to the controller module. The controller module triggers the alarm module to stop the alarm based on the stop alarm instruction. Specifically, for example, the controller module transmits an electrical signal (such as a low level) to the alarm module to trigger the alarm module to stop working. In addition, the external device can determine whether the electronic device is located in a pre-set target area based on the received indoor positioning information and / or outdoor positioning information. If the electronic device is not located in the target area, an alarm instruction can be sent to the communication module. If the electronic device enters the target area from an illegal area (an area outside the target area) within a short period of time, a stop alarm instruction can be sent to the communication module.

[0081] Specifically, the alarm module includes one or more of a buzzer, an indicator light, and an audible and visual alarm. In other words, the alarm module has both audible and visual alarm functions. Thus, when it is determined that the electronic device has left a specific location area (the aforementioned target area), the buzzer generates a periodic alarm, and the indicator light flashes periodically to provide an alarm.

[0082] Furthermore, as an optional implementation, the electronic device further includes:

[0083] A power module, which is responsible for power supply and power management of the entire electronic device; wherein the power module includes a rechargeable battery, which provides operating voltage for the first positioning module, the second positioning module, the data damage module, the storage module and the controller module.

[0084] 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, the data damage module, the storage module and the controller module. In this way, after the power supply of the electronic device is disconnected, the power module can provide an operating voltage for each of the above modules to ensure that the 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 electronic device in a timely manner and avoid the data in the storage module of the electronic device from being illegally stolen.

[0085] Furthermore, as an optional implementation, the electronic device further includes:

[0086] A first antenna interface is embedded in the housing of the electronic device and connected to the first positioning module. For example, the first antenna interface may adopt a Sub Miniature Version A (SMA) interface. 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. 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.

[0087] a first antenna located outside the housing and connected to the first antenna interface; wherein the first antenna is disposed outside the housing to prevent the first antenna from being unable to normally transmit and receive signals due to shielding by the housing;

[0088] 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.

[0089] a second antenna located outside the housing and connected to the second antenna interface; similarly, the second antenna being located outside the housing can prevent the second antenna from being unable to normally receive and transmit signals due to shielding by the housing;

[0090] A communication antenna interface is embedded in the housing and connected to the communication module; the communication antenna interface can be the same as the first antenna interface and the second antenna interface, both of which adopt SMA interface form; the communication antenna interface and the communication positioning module are also connected via an IPX to SMA cable;

[0091] The communication antenna is located outside the shell and is connected to the communication antenna interface; similarly, the communication antenna is arranged outside the shell, which can avoid the communication antenna being unable to normally receive and send signals due to the shielding of the shell.

[0092] That is to say, the electronic device also includes an antenna device, which includes the first antenna interface and first antenna, the second antenna interface and second antenna, the communication antenna interface and communication antenna as described above, so as to transmit and receive signals with the corresponding equipment (satellite / base station / gateway / cloud device, etc.) through the antenna device to ensure stable reception and transmission of signals.

[0093] As a specific implementation method, when the controller module transmits the outdoor positioning information and / or the indoor positioning information to the communication module, it also transmits the time information and / or the device identification to the communication module. When the communication module transmits the outdoor positioning information and / or the indoor positioning information to the external device, it also transmits the time information and / or the device identification to the external device, wherein the time information represents the acquisition time of the outdoor positioning signal and / or the indoor positioning signal, and the device identification is provided by the security chip of the electronic device to avoid the device identification of the electronic device from being illegally tampered with. In this way, the external device can locate a specific electronic device (the electronic device indicated by the device identification) based on the received information and control the electronic device (alarm or destroy data).

[0094] In addition, the external device can also transmit pre-set data, such as electronic fence / target area, to the control module through the communication module. When the electronic device is at different stages of its life cycle, the electronic fence / target area is different, that is, different stages of the life cycle of the electronic device correspond to different electronic fences / target areas. In this way, the positioning of the electronic device throughout its life cycle and the determination of whether the electronic device is located in a legal area are achieved, thereby ensuring the data security of the electronic device throughout its life cycle.

[0095] As an optional implementation, the external device sends the first control instruction to the communication module, the communication module transmits the first control instruction to the controller module, and the controller module transmits the first control instruction to the data destruction module; that is, the first control instruction transmitted by the controller module to the data destruction module is generated by the external device and transmitted to the controller module via the communication module;

[0096] or,

[0097] When it is detected that the electronic device is located in an area outside the target area, the controller module transmits a first control instruction representing the damaged data to the data damage module; in this case, monitoring whether the electronic device is located in the target area can specifically be to compare the received outdoor positioning information and / or indoor positioning information with the coordinates corresponding to the target area, and determine whether the position corresponding to the outdoor positioning information and / or indoor positioning information is within the target area; if not (for example, not in the target area within a preset time period), then the first control instruction representing the damaged data is transmitted to the data damage module; wherein, as an example, the monitoring process can be implemented by the controller module.

[0098] As an optional implementation, the data destruction module destroys the data in the storage module including:

[0099] The data destruction module inputs a preset current into the storage module to destroy the storage module. This method is hardware destruction, that is, by destroying the hardware (storage module), the data in the storage module is destroyed, making the data in the storage module unreadable. It should be noted that data destroyed in this destruction method cannot be recovered.

[0100] And / or, the data destruction module inputs a data erasure instruction to the storage module; this method is software destruction, that is, by overwriting the data in the storage module, the data in the storage module cannot be read. It should be noted that the data destroyed by this destruction method can be recovered.

[0101] Below, taking the first positioning module as a Beidou satellite positioning module, the second positioning module as a UWB positioning module, and the communication module as a Cat.1 communication module as an example, the implementation process of the damaged data in the embodiment of the present application is described in detail:

[0102] 1.1a: When the electronic device is in an outdoor environment, the Beidou satellite positioning module receives signals from Beidou satellites and transmits the signals to the controller module. The controller module parses the Beidou satellite signals and calculates the outdoor location coordinate data of the electronic device (corresponding to the aforementioned outdoor positioning information).

[0103] 1.1b: When the hard drive enters an indoor environment, the UWB positioning module begins operating. It transmits a pulsed radio signal, which is received by an indoor UWB base station and returned as a feedback signal. Based on the signal from the UWB base station, the controller module calculates the indoor location coordinates of the electronic device (corresponding to the aforementioned indoor positioning information).

[0104] The above steps 1.1a and 1.1b may be performed only one or both depending on the actual situation. Specifically, the above steps 1.1a and 1.1b are performed passively, that is, the Beidou satellite positioning module passively receives signals from Beidou satellites, and the controller module passively receives signals fed back by the UWB base station. Specifically, when located in an area covered by both the Beidou satellite positioning module and the UWB positioning module (such as the area at the junction of indoor and outdoor areas), the above steps 1.1a and 1.1b are performed simultaneously.

[0105] 1.2a: The controller module transmits outdoor positioning information and indoor positioning information (if the controller module obtains it) to the data center through the Cat.1 communication module;

[0106] 1.2b: The controller module determines whether the electronic device is located in a preset target area based on the acquired outdoor positioning information and / or indoor positioning information;

[0107] In this example, there is no restriction on the execution order of 1.2a and 1.2b. You can execute 1.2a first and then 1.2b, or 1.2b first and then 1.2a, or you can execute 1.2a and 1.2b simultaneously.

[0108] 1.3: After 1.2a, the data center determines whether the electronic device is located in a preset target area based on the acquired outdoor positioning information and / or indoor positioning information; if not, an alarm instruction is transmitted to the Cat.1 communication module, which transmits the alarm instruction to the controller module, and the controller module triggers the alarm module to alarm; if the electronic device is not located in the target area for a first preset time period, a first control instruction is transmitted to the Cat.1 communication module, indicating that data in the storage module is to be destroyed by software destruction, which is transmitted to the Cat.1 communication module, which transmits the first control instruction to the controller module, which transmits the first control instruction to the data destruction module, which sends a data erasure instruction to the storage module to erase the data in the destruction module; if the electronic device is not located in the target area for a second preset time period, a first control instruction is transmitted to the Cat.1 communication module, indicating that data in the storage module is to be destroyed by hardware destruction, which is transmitted to the Cat.1 communication module, which transmits the first control instruction to the data destruction module, which increases the current input to the storage module to destroy the storage module, thereby destroying the data in the storage module;

[0109] 1.4: After 1.2b, if it is determined that the electronic device is not located in the target area, the alarm module is triggered to sound an alarm; if the duration of time the electronic device is not located in the target area reaches a first preset duration, the controller module transmits a first control instruction to the data destruction module instructing the data in the storage module to be destroyed by software destruction, and the data destruction module sends a data erasure instruction to the storage module to erase the data in the destruction module; if the duration of time the electronic device is not located in the target area reaches a second preset duration, the controller module transmits a first control instruction to the data destruction module instructing the data in the storage module to be destroyed by hardware destruction, and the data destruction module increases the current input to the storage module to destroy the storage module, thereby destroying the data in the storage module;

[0110] Here, it should be noted that the above step 1.4 is executed when the controller module determines that the electronic device is not located in the target area and does not obtain the first control instruction transmitted by the Cat.1 communication module (for example, when the network is abnormal or the electronic device is blocked);

[0111] Here, the process of determining whether the electronic device is located in a preset target area in 1.2b and 1.3 is explained. If only outdoor positioning information or indoor positioning information is obtained, whether the electronic device is located in the preset target area is determined based on the obtained outdoor positioning information or indoor positioning information. If both outdoor positioning information and indoor positioning information are obtained at the same time, data processing is performed on the outdoor positioning information and the indoor positioning information based on the signal strength of the outdoor positioning information and the signal strength of the indoor positioning information (such as direct weighting or averaging, or screening relatively accurate location information based on the signal strength of the outdoor positioning information and the indoor positioning information.
