Description

Technical Field

[0001] This utility model relates to the field of communication technology, and more specifically, to a laptop anti-loss device. Background Technology

[0002] Currently, laptop anti-loss devices use the laptop's built-in positioning device for location tracking, which cannot be used to locate and retrieve the laptop when it is powered off. Furthermore, existing laptop anti-loss devices require connection to an external network when traveling, posing a significant security risk of information leakage. Utility Model Content

[0003] This invention provides a notebook anti-loss device to solve the above-mentioned technical problems.

[0004] This utility model is achieved through the following technical solution:

[0005] A laptop anti-loss device includes a black box, which comprises a main control chip, a Bluetooth module, a GPS module, a Wi-Fi module, a buzzer, a communication module, and a power module. The Bluetooth module, GPS module, Wi-Fi module, buzzer, communication module, and power module are all connected to the main control chip.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1 As shown, the laptop anti-loss device disclosed in this embodiment includes a black box and a server.

[0032] The black box includes a main control chip, a Bluetooth module, a GPS module, a Wi-Fi module, a buzzer, a communication module, and a power module. The Bluetooth module, GPS module, Wi-Fi module, buzzer, communication module, and power module are all connected to the main control chip, and the power module is used to supply power to the device.

[0033] Of course, the black box needs to be physically bound to a laptop for use, and can be connected to the anti-loss device using the computer's built-in USB port.

[0034] The Bluetooth module is connected and used to determine the distance between the laptop and the black box. Bluetooth devices can estimate the approximate distance between them using the Signal Strength Indicator (RSS I). A higher RSS I value likely indicates that the devices are closer; RSS I is converted into distance using a formula.

[0035] The Bluetooth module is used for Bluetooth connection with the client. When the Bluetooth module is disconnected from the client / mobile / handheld terminal, the buzzer sounds an alarm, making it easy for the user to quickly find the laptop based on the alarm sound.

[0036] The GPS module is used to locate the black box. The communication interface of the GPS module is connected to the main control chip to collect data and observe time, longitude, latitude and altitude in real time, so as to facilitate the location information.

[0037] The WIFI module can be used to provide network access for laptops, avoiding the information leakage security risks that arise when connecting to the external network while on business trips. At the same time, it can upload real-time GPS data to the cloud platform, allowing administrators to monitor the computer's location in real time.

[0038] The communication module can make phone calls to remind users that their computers are lost, and send real-time location information (longitude, latitude, altitude, and speed) via SMS to the user's mobile phone to help the user quickly retrieve their computer.

[0039] The server includes a cloud server for locating and tracking the position of the anti-loss device.

[0040] The client device can be a mobile phone or a smartwatch. For example, it connects to the mobile phone via a Bluetooth module. When the distance between the black box, laptop, and mobile phone is within a set distance range, the Bluetooth module maintains the connection with the mobile phone; when the distance between the black box, laptop, and mobile phone exceeds the set distance, Bluetooth is disconnected, and a buzzer sounds.

[0041] In one possible design, when the Bluetooth module is connected to the mobile phone, the red light on the Bluetooth module flashes twice in succession with a long interval between each flash.

[0042] In one possible design, the black box has a charging port that connects to the power module for charging the power module.

[0043] In one possible design, the main control chip is selected as STM32F103ZET, the Bluetooth module is selected as HC05, the WIFI module is selected as ESP8266, the GPS module is selected as ATK1218-BD, and the communication module is selected as SIM800C.

[0044] Figure 5 The 3-jump wire of P is explained as follows:

[0045] If the voltage regulator circuit provides a stable 5V, then simply short-circuit P3 as default.

[0046] If you are using USB power or a USB-TTL module outputting 5V for debugging, in most cases you can simply short-circuit P3 by default (most computer USB outputs will be lower than 5V).

[0047] If you are using a 5V power adapter, please measure the output voltage with a multimeter beforehand (many power adapters have an output voltage of 5.2-5.4V).

[0048] If the adapter or computer USB output voltage exceeds 5.1V, the short-circuited part of P3 needs to be removed with a soldering iron to ensure the core operating voltage VBAT is normal. Principle: D1 drops the voltage by 0.7V, and D2 drops the voltage by 0.3V.

[0049] In practical use, select whether to short-circuit P3 according to your own VCC input voltage to make VAT meet the voltage range of 3.4V-4.4V.

[0050] Too low a voltage will cause the module to shut down automatically, while too high a voltage will burn out the core, resulting in irreparable damage.

[0051] It is also worth mentioning that, Figure 5 Only TXD and RXD can be directly connected to the IO control of a 5V / 3.3V microcontroller with a VCC input voltage of 5V;

[0052] V_TLL connects to the core power supply of your microcontroller board (5V / 3.3V).

[0053] TXD and RXD will automatically switch to the required logic level according to the V_TTL voltage.

[0054] A short circuit between PWR and GND can automatically power on and start the module.

[0055] In one possible design, the communication module is connected to a 3.7V lithium battery, which is used to power the communication module separately.

[0056] In one possible design, the server includes the PC-based ONENET platform.

[0057] In one possible design, the cloud server sets up an interface to receive location information sent from the mobile application.

[0058] Furthermore, by writing code on the cloud server, these locations can be displayed in a suitable way on cloud applications or web interfaces based on the stored location information; this technology includes generating map markers, path lines, or visualizations of other geographic information, which are conventional technologies in this field and will not be elaborated here.

[0059] When using this utility model, the Bluetooth module connects to the client. When the distance between the client and the black box exceeds the system-set distance, the Bluetooth connection is lost and the black box sounds an alarm. When a customer loses their computer, the communication module sends a text message containing location information to the customer's mobile phone and makes a phone call to remind the user that the computer is lost. The user can then locate the laptop based on the received location information.

[0060] The Wi-Fi module uploads location information such as longitude and latitude to the cloud platform. Administrators can control the server to view the location of the black box and laptop through the cloud map. This technology is used for remote monitoring of employees.

[0061] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
