s1, the base station 10 receives the online report of the external Bluetooth tag 301 installed outside the safe 30, the door opening report of the door opening Bluetooth tag 302 installed inside the safe 30 and the asset report of the asset Bluetooth tag 303 attached to the anti-theft article inside the safe 30 at regular time;
s2, the base station 10 determines whether the safe is moved out of the safe range according to the status information of the online report, and sends the status information of the online report to the mobile terminal 20;
s3, the base station 10 determines whether the safe door is opened according to the determination result of whether the safe is moved out of the safe range and the state information of the door opening report, and sends the state information of the door opening report to the mobile terminal 20;
s4, the base station 10 determines whether the stolen goods in the safe 30 are moved out of the safe range and placed back into the safe 30 according to the determination result of whether the safe door is opened and the status information of the asset report, and sends the status information of the asset report to the mobile terminal 20.
Step S2 specifically includes:
s21, if the base station 10 receives the online report, it determines that the safe 30 is not moved out of the safe range; if the base station 10 does not receive the online report at the preset time interval, it is determined that the safe 30 is moved out of the safety range, the base station 10 sends out a warning sound prompt and sends warning information to the mobile terminal 20, and the mobile terminal 20 also sends out a warning sound prompt at the same time. The base station 10 may also send alarm information to the external bluetooth tag 301, and the external bluetooth tag 301 may also send an alarm prompt.
Step S3 specifically includes:
s31, when the safe 30 is determined not to be moved out of the safe range, if the base station end 10 receives the door opening report, the door of the safe is judged to be opened; if the base station terminal 10 does not receive the door opening report at the preset number of time intervals, it is determined that the safe door is closed.
Step S4 specifically includes:
s41, when it is determined that the door of the safe is opened, if the base station 10 does not receive the asset report at the time interval of the preset amount, it is determined that the theft-proof object in the safe 30 is moved out of the safe range, and the base station 10 sends out an alarm sound prompt and sends an alarm message to the mobile terminal 20; the mobile terminal 20 also sends out a warning sound. The base station 10 may also send alarm information to the asset bluetooth tag 303, and the asset bluetooth tag 303 may also send a warning sound.
When it is determined that the safe door is closed, if the base station 10 still receives the asset report, it is determined that the stolen-proof object in the safe 10 is not put back into the safe 10, and a prompt message is sent to the mobile terminal 20.
The method realizes the anti-theft and door opening and closing state monitoring of the safety box, wherein the base station end 10 mainly refers to an electronic fence base station end, and the mobile terminal mainly refers to a mobile phone, specifically a mobile phone APP. And a communication pair is composed of a plurality of Bluetooth tags and a base station end 10 (electronic fence base station end). The preset number of time intervals is three in the present embodiment, and may be two or four in other embodiments.
Bluetooth tags are mounted on items that are to be stolen, typically referred to as valuables, outside, inside safe 30 and inside safe 30, respectively. The Bluetooth tag arranged outside the safe 30 is called as an external Bluetooth tag 301, the Bluetooth tag arranged inside the safe 30 is divided into a door opening Bluetooth tag 302 and an asset Bluetooth tag 303, the door opening Bluetooth tag 302 is used for sending a door opening report to the base station end 10 (electronic fence base station end), and the asset Bluetooth tag 303 is attached to the valuable articles which are stolen and lost in the safe 30 and used for monitoring the valuable articles. The external Bluetooth tag 301 is installed outside the safe 30, and regularly sends an online report customized by a specific protocol to the base station end 10 (electronic fence base station end) at time intervals, and when the base station end 10 (electronic fence base station end) does not receive the online report of the external Bluetooth tag 301 at 3 time intervals, the external Bluetooth tag sends alarm information to the mobile terminal 20 (mobile phone APP), and the external Bluetooth tag also sends an alarm sound; the door opening Bluetooth tag 302 is installed inside the safe 30, and also sends a door opening report customized in a specific format to the base station terminal 10 (electronic fence base station terminal) at a specific time interval, because the safe 30 is closed and shields wireless communication signals, when the safe door is not opened, the door opening report cannot be transmitted to the base station terminal 10 (electronic fence base station terminal), and therefore when the base station terminal 10 (electronic fence base station terminal) receives the door opening report, it indicates that the safe door is opened; when the door opening report is not received in 3 time intervals, the safe door can be judged to be closed. The asset bluetooth tag 303 is attached to a protected and loss-proof valuable item, and can be in the shape of a bookmark or a pendant. The asset bluetooth tag 303 also sends asset reports in a specific format to the base station end 10 (electronic fence base station end) at regular time intervals. When the safe door is closed, the base station end 10 (electronic fence base station end) cannot receive the asset report of the stolen goods due to signal shielding; when the safe door is opened, the base station terminal 10 (electronic fence base station terminal) starts to receive the asset report after receiving the door opening report, and sends the asset report state to the mobile terminal 20 (mobile phone APP) through INTERNET. When the safe door is not closed and the corresponding asset report is not sent to the base station end 10 (electronic fence base station end) at 3 time intervals, the base station end 10 (electronic fence base station end) judges that the corresponding theft-proof article is moved out of the monitoring area, namely the safety range, alarms to the mobile terminal 20 (mobile phone APP), and sends out warning sound; when the safe door is closed and the corresponding asset report is received, the stolen-proof article is judged not to be put back into the safe 30, and a prompt message report is sent to the mobile terminal 20 (mobile phone APP).
The reports sent by the external bluetooth tag 301, the door-open bluetooth tag 302 and the asset bluetooth tag 303 to the base station 10 are called an online report, a door-open report and an asset report, respectively, and have the following formats: header (2 bytes) + message type (1 byte) + device number (1 byte) + check code (2 bytes). Wherein, the header is a leader sequence and consists of a 16-system code A5A 5; the message type is defined as: 0 xFE: online report, 0x0 FF: door open report, 0x00- -0 xFD: asset reports and doubles as asset numbers, i.e., manageable assets numbers from 0-0xFD, up to 253. The equipment number is the number of the safe case, and the value range is 0-255. The check code adopts standard CRC check to check the information of the 1 st to the 4 th bytes of the message.
Judging whether the anti-theft articles are still controlled within the safety range of the safe case or not by utilizing the communication connection condition between the base station end 10 (electronic fence base station end) and the Bluetooth ends on the external Bluetooth tag 301, the door opening Bluetooth tag 302 and the asset Bluetooth tag 303; support to dynamically set an alarm context on the mobile terminal 20 (mobile APP), mainly including but not limited to: the signal intensity is continuously weakened, connection interruption and signal shielding are performed, or the electric quantity of the bluetooth terminals on the base station terminal 10, the external bluetooth tag 301, the door-opening bluetooth tag 302 and the asset bluetooth tag 303 is insufficient, and the like. Specifically, the base station end 10 (e.g., the electronic fence base station end) obtains the signal intensity and the power information from the external bluetooth tag 301, the door-opening bluetooth tag 302, or the bluetooth end of the asset bluetooth tag 303, and when the signal intensity and the power information exceed the preset condition threshold, the base station end 10 (e.g., the electronic fence base station end) sends the alarm information to the mobile terminal 20 (e.g., the mobile APP), and also can simultaneously send the alarm information to the external bluetooth tag 301, the door-opening bluetooth tag 302, or the asset bluetooth tag 303, so that the mobile terminal 20 (e.g., the mobile APP), the base station end 10 (e.g., the electronic fence base station end) and the external bluetooth tag 301, the door-opening bluetooth tag 302, or the. By selecting and utilizing the algorithm, the false alarm rate of a safe theft-proof system is minimized, and the service life rate of the battery of the object label is maximized. The APP software can automatically detect a new version and upgrade the firmware of the base station 10 (base station of the electronic fence) and the tag of the anti-theft object.
Further, referring to fig. 2 and fig. 3, the present invention also provides a flow chart of locating and finding the safe and a flow chart of locating and finding the theft-proof article in the intelligent theft-proof method for the safe according to the second embodiment of the present invention.
In the second embodiment, when it is determined that the safe 30 is moved out of the safe range, after step S21, the method further includes:
s22, the base station 10 acquires the position sensing information of the safe 30;
s23, the base station 10 accurately positions the position of the safe 30 based on the position sensing information;
and S24, calculating the distance between the safe 30 and the base station end 10 and the mobile terminal 20 respectively.
When it is determined that the item to be stolen in the safe 30 is moved out of the safe range, the method further includes, after step S41:
s42, the base station 10 acquires the position sensing information of the stolen-proof articles in the safe 30;
s43, the base station terminal 10 accurately positions the position of the theft-proof article based on the position perception information;
s44, the base station 10 calculates the distance between the article to be stolen and the base station 10 and the mobile terminal 20 respectively.
The base station 10 (electronic fence base station) forms alarm information, encrypts and transmits the alarm information to the mobile terminal 20 (mobile phone APP), and gives an alarm together with the mobile terminal 20 (mobile phone APP) and a tag end on an object to be stolen (indicating a safe or an article to be stolen in the safe). Meanwhile, the mobile phone mobile terminal 20 (mobile phone APP) enables a fast positioning and searching function.
The base station 10 (electronic fence base station) obtains the corresponding location sensing information of the theft-proof object by positioning the bluetooth end on the bluetooth tag of the theft-proof object (referring to the safe or the theft-proof object in the safe). In this embodiment, the location awareness information includes: the location of the base station end 10, the location of the bluetooth end of the bluetooth tag of the loss-deterrent object (including the external bluetooth tag 301 and the asset bluetooth tag 303), absolute positioning calculations, communication connection disconnection time records, etc. are known.
