1 is a functional block diagram of a preferred embodiment of the Bluetooth anti-theft early warning system of the present invention.

2 is a flow chart of a preferred embodiment of the Bluetooth anti-theft warning method of the present invention.

As shown in FIG. 1, it is a functional module diagram of a preferred embodiment of the Bluetooth anti-theft early warning system of the present invention. The Bluetooth anti-theft early warning system (hereinafter referred to as "early warning system") 2 is installed in the electronic device 1 and the lock head 3, respectively, for issuing early warning information to the electronic device 1 when an abnormality occurs in the lock head 3. The electronic device 1 and the lock 3 respectively mount the Bluetooth device 10 and the Bluetooth device 30 for realizing the establishment of the electronic device 1 and the lock 3 Wire connections and transfer related information.

The lock 3 further includes a battery 32 for providing power to the lock 3 to ensure proper operation of the early warning system 2. The battery 32 may be a rechargeable battery or a general battery. In other embodiments, the lock 3 can also be directly connected to a power source.

The lock 3 can be a key lock or a combination lock. The password lock includes a push-button lock and a dial-type lock. In the present embodiment, a push-button lock is taken as an example for description. As shown in Figure 1, the lock 3 further includes a keyboard 34 for the user to enter the unlocked password.

The electronic device 1 may be a desktop computer, a notebook computer, a mobile phone or the like, which can communicate with the lock, and receive an early warning signal and generate relevant instructions to prompt the early warning information. The electronic device 1 includes a display screen 12 and a speaker 14. The display screen 12 can display early warning information, and the speaker 14 can issue an early warning sound to prompt the user to pay attention.

The early warning system 2 is opened by the following steps: the Bluetooth device 10 of the electronic device 1 is connected with the Bluetooth device 30 of the lock 3, and the Bluetooth device is connected and paired, thereby opening the device. The early warning system 2 described.

The early warning system 2 mainly includes three functional modules, namely: an induction module 20, a conversion module 22, and an early warning module 24.

The sensing module 20 is configured to detect whether the lock 3 is attempted to be opened by an external force, and generate an analog analog signal when an external force is detected to attempt to open the lock 3. In the embodiment, the sensing module 20 further includes a sensor 200, the feeling The charger 200 is disposed at the bottom of the keyboard 34 for detecting whether a button on the keyboard 34 is pressed. When the sensor 200 detects that the button on the keyboard 34 is pressed, the sensing module 20 is configured to generate an analog analog signal and transmit the analog signal to the conversion module 22.

In other embodiments, if the lock is a key lock, the sensor 200 can be placed at the bottom of the lock cylinder for sensing whether the lock cylinder is rotated.

The conversion module 22 is configured to receive the analog signal, convert the analog signal into a digital signal, and transmit the digital signal to the Bluetooth device 30 of the lock 3. The Bluetooth device 30 transmits the digital signal to the Bluetooth device 10 of the electronic device 1 by means of its wireless connection with the Bluetooth device 10 of the electronic device 1. After the Bluetooth device 10 acquires the digital signal, the digital signal is transmitted to the early warning module 24.

The warning module 24 is configured to generate a corresponding early warning command according to the digital signal, so that the electronic device 1 issues a corresponding early warning, including: transmitting the early warning command to the display screen 12 and/or the speaker 14 The display screen 12 displays warning information and/or causes the speaker 14 to emit an early warning sound. The warning information is preset by the early warning module 24, for example, it can be preset as “please pay attention to the door lock security”; the warning sound is also preset by the early warning module 24 .

The user can set different warning modes by using the early warning module 24 according to individual needs, for example, setting warning information, issuing an early warning sound, or a combination of the two. When the electronic device 1 is a mobile phone, the early warning mode may further include a vibration prompt.

In the present embodiment, if the user himself unlocks, the early warning system 2 can be turned off by the Bluetooth connection between the electronic device 1 and the lock 3, or can be received by the early warning system 2 After the warning, the warning is cancelled on the electronic device 1, for example, the display of the warning information is cancelled and/or the warning sound is cancelled.

2 is a flow chart of a preferred embodiment of the Bluetooth anti-theft warning method of the present invention. First, in step S2, the lock 3 is opened, that is, the lock 3 is energized. If the lock 3 is currently energized, this step can be omitted.

In step S4, the Bluetooth device 10 of the electronic device 1 and the Bluetooth device 30 of the lock 3 establish a Bluetooth wireless connection and perform pairing.

In step S6, the electronic device 1 uses the Bluetooth wireless connection to open the early warning system 2 installed on the electronic device 1 and the lock.

In step S8, the sensor 200 detects whether a button on the keyboard 34 is pressed. If it is pressed, step S10 is performed; otherwise, the flow returns to step S8 to continue the detection.

In step S10, the sensing module 20 generates an analog analog signal and transmits the analog signal to the conversion module 22.

In step S12, the conversion module 22 receives the analog signal, converts the analog signal into a digital signal, and transmits the digital signal to the Bluetooth device 30 of the lock 3.

Step S14, the Bluetooth device 30 transmits the digital signal to the Bluetooth device of the electronic device 1 by using the wireless connection between the Bluetooth device 30 and the Bluetooth device 10 of the electronic device 1. After the digital device 10 acquires the digital signal, the digital signal is transmitted to the early warning module 24.

In step S16, the early warning module 24 generates a corresponding early warning instruction according to the digital signal.

In step S18, the early warning module 24 transmits the warning command to the display screen 12 and/or the speaker 14, so that the display screen 12 displays the warning information, and/or causes the speaker 14 to issue an early warning sound. And then end this process.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
