Example 1
As shown in fig. 1, the present embodiment provides a door opening system of a bluetooth induction lock, including: set up bluetooth response module, radar ranging module and the control module in bluetooth response lock, still include: a Bluetooth key.
The radar ranging module is used for detecting the distance between users outside the door and sending a detection signal to the control module.
The Bluetooth induction module is used for receiving an unlocking signal of the Bluetooth transmitting module and sending the signal to the control module.
The Bluetooth key is mobile communication equipment inserted with an SIM card, and a Bluetooth transmitting module is integrated on the SIM card; the mobile communication equipment is a mobile phone, and the Bluetooth transmitting module can automatically send signals to the Bluetooth sensing module through a power supply of the mobile phone; and a security chip is further integrated on the SIM card and used for protecting the information of the Bluetooth key. In addition, as an alternative embodiment, the mobile phone can also adopt other mobile communication equipment suitable for inserting the SIM card.
The Bluetooth induction module detects the intensity of the received unlocking signal of the Bluetooth key by adopting a Bluetooth directional antenna, and the Bluetooth directional antenna points outdoors and is in signal connection with the control module.
The control module receives the signals of the Bluetooth induction module and the radar ranging module respectively and judges: whether the Bluetooth key passes the safety certification, whether the user is outside the door or not, and whether the user moves to a preset distance outside the door or not, and sends a signal to unlock the door.
Example 2
This example provides an unlocking method of a bluetooth induction lock, as shown in fig. 2, including the following steps:
step S1: receiving an unlocking signal of a Bluetooth key, performing security authentication on the Bluetooth key, and executing the next step if the authentication is passed; the Bluetooth key is mobile communication equipment inserted with an SIM (subscriber identity module), a Bluetooth transmitting module is integrated on the mobile communication equipment, and the Bluetooth transmitting module can automatically send signals to a Bluetooth induction module through a power supply of the mobile communication equipment; when the mobile communication equipment approaches to the Bluetooth induction lock, a Bluetooth induction module on the Bluetooth induction lock automatically scans and receives signals of the Bluetooth transmitting module and performs Bluetooth connection with the mobile communication; for the safety of opening a door by the Bluetooth induction lock, malicious door opening is prevented, after the Bluetooth induction lock is in Bluetooth connection with the mobile communication, the Bluetooth induction lock performs safety authentication on the mobile communication equipment, the algorithm of the safety authentication adopts an AES (advanced encryption standard) algorithm, and the secret key of each Bluetooth key safety algorithm has uniqueness.
Step S12: and after the Bluetooth key is subjected to security authentication, judging whether the Bluetooth key is out of the door, and if so, executing the next step. Specifically, the bluetooth directional antenna is integrated on the bluetooth induction lock, and the bluetooth directional antenna points to the outside of the door. And when the signal intensity of the Bluetooth transmitting module received by the Bluetooth directional antenna is greater than a preset threshold value, judging that the Bluetooth key is positioned outdoors. And the preset threshold value is determined by taking the strongest signal in the gate as a reference signal and adding a revision value of 5-10 db on the basis of the reference signal.
Step S2: the user distance outside the door is detected. Specifically, the bluetooth response is locked to be integrated with radar ranging module, radar ranging module adopts TOF laser radar, detects the user distance outdoors through radar ranging module.
Step S3: and judging whether the user outside the door is at a preset door opening distance or not, and if so, executing the next step. The radar ranging module sends a detection signal to the control module, and the control module judges whether a user is in a preset door opening distance.
Step S4: and (6) unlocking.
In this embodiment, before unlocking, the bluetooth key needs to be registered first.
As shown in fig. 3, the step of registering the bluetooth key is as follows:
step 1: setting a Bluetooth PIN code; when the bluetooth response is opened the door, the prerequisite is that to carry out the bluetooth authentication, and every bluetooth key all has a unique PIN code, and the PIN code is the key of bluetooth authentication algorithm, and when bluetooth response lock connected user's bluetooth key, the bluetooth key carries out safety certification according to bluetooth safety certification flow through the PIN code, and safety certification passes through the back, can carry out the bluetooth response and open the door.
The user registers bluetooth key operation suggestion according to the APP on the APP customer end, inputs bluetooth key PIN code, and after the bluetooth response lock received APP customer end and registers bluetooth key instruction, the system will generate a user information list, and the information list contains bluetooth key PIN code, bluetooth response door opening distance, the internal reference signal of bluetooth response door opening.
Step 2: measuring an in-door signal; after bluetooth PIN sign indicating number setting is accomplished to bluetooth response lock, signal measurement step in bluetooth response lock initiating door, every 200ms acquires the signal of a bluetooth key and sends for the APP customer end, the user searches the bluetooth signal about 1 meter in the door, the strongest signal in APP customer end meeting automatic recording door, after the user searches to accomplish clicks the decision button for use, send indoor reference signal and give bluetooth response lock, the back is received to bluetooth response lock, in preserving this user information table to indoor reference signal value.
And 3, step 3: setting the door opening distance of the door; when the Bluetooth key is registered, the door opening distance outside the door needs to be set, and the Bluetooth key user opens the door and can open the door only when the set door opening distance is reached; when the bluetooth key registers, accomplish the interior signal measurement step back of door, carry out the distance setting of opening door outward, the bluetooth response lock initiates the distance setting step of opening door outward, and the user of uploading every 200ms of bluetooth response lock gives the APP customer end from the distance of bluetooth response lock, and distance message can show in real time on the APP interface, and convenience of customers looks over, after the user clicks the confirm button on the APP interface for use, and the distance setting of opening door outward is accomplished.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
