It is to be noted that the experimental methods described in the following embodiments are all conventional methods unless otherwise specified, and the reagents and materials, if not otherwise specified, are commercially available; in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The iBeacon is a positioning beacon node released by apple corporation, the iBeacon node periodically broadcasts outwards, and the distance between the beacon node and receiving equipment is calculated by detecting the broadcast sending intensity of the iBeacon node, so that the position information of the beacon is determined.
In the prior art, the iBeacon node broadcasts information periodically all the time, but only the broadcast information received in the positioning time period is useful information, and most of the other broadcast information is useless broadcast information, so that the power consumption and the efficient utilization of broadcast signals cannot be realized, and the broadcast signal pollution is also caused.
In order to overcome the above problems in the prior art, an embodiment of the present invention provides an anti-fake bluetooth transmission device, which transmits a bluetooth signal containing its unique identifier to the surroundings according to a BLE technology, and the anti-fake bluetooth transmission device adjusts a transmission state of the bluetooth signal according to a current motion state;
the sending state comprises the awakening duration of the anti-counterfeiting Bluetooth sending equipment and the sending times in unit time.
It should be noted that the anti-fake bluetooth sending device in the embodiment of the present invention adjusts the sending state of the bluetooth signal according to the motion state, and has corresponding wake-up duration in different motion states, and sends the bluetooth signal only when waking up, and has different sending times in unit time in different motion states, thereby overcoming the problems of large power consumption and broadcast signal pollution caused by the anti-fake bluetooth sending device sending the bluetooth information in a fixed sending period in the prior art.
On the basis of the above embodiment, fig. 1 shows a functional block diagram of an anti-counterfeit bluetooth transmission device, and referring to fig. 1, the anti-counterfeit bluetooth transmission device according to the embodiment of the present invention includes:
and the dynamic and static detection module is used for monitoring and transmitting the motion degree of the anti-counterfeiting Bluetooth transmitting equipment after the anti-counterfeiting Bluetooth transmitting equipment is started.
For the dynamic and static detection module, the dynamic and static detection module can represent the motion degree of the anti-counterfeiting Bluetooth sending equipment through recording the acceleration, and the motion degree is larger when the acceleration is larger.
The processor is connected with the dynamic and static detection module and used for receiving the motion degree sent by the dynamic and static detection module and sending a first instruction according to the fact that the motion degree exceeds a preset motion degree threshold; and sending a second instruction according to the fact that the motion degree is lower than a preset static degree threshold value after the first instruction is sent.
The signal sending module is connected with the processor and is used for:
according to a first instruction, sending a Bluetooth signal in a first sending state;
according to a second instruction, sending a Bluetooth signal in a second sending state;
wherein the number of transmissions per unit time in the first transmission state is greater than the number of transmissions per unit time in the second transmission state.
For the processor, the processor is responsible for adjusting the sending state of the anti-counterfeiting Bluetooth sending device according to the change of the motion degree, when the motion degree of the anti-counterfeiting Bluetooth sending device exceeds a preset motion degree threshold value, it is indicated that the anti-counterfeiting Bluetooth sending device may obviously move, at this time, the processor sends a first instruction, and the signal sending module sends the Bluetooth signal in a first sending state according to the first instruction. In the embodiment of the invention, the static state can also be considered as a normal state or a safe state, therefore, when the anti-counterfeiting Bluetooth transmitting equipment is in the static state, the processor can transmit a second instruction, the letter transmitting module transmits a Bluetooth signal in the second transmitting state according to the second instruction, and the number of times of transmission in unit time of the second transmitting state is less than that in unit time of the first transmitting state, so that the power consumption of the processor can be saved.
For the motion level threshold, 250mg (mg is the acceleration unit) can be designed. For the threshold of the degree of quiescence, 150mg can be designed.
The above embodiment is suitable for the situation with high requirement on the motion degree of the anti-counterfeiting Bluetooth transmitting device, such as a museum, an exhibition hall and the like, that is, the transmitting state is changed as long as the motion degree of the anti-counterfeiting Bluetooth transmitting device is lower than the preset stationary degree threshold value or higher than the preset motion degree threshold value. In some scenarios, however, it is not necessary for the anti-counterfeit bluetooth transmission device to be so sensitive to change transmission status, and therefore, in another embodiment, the processor sends the first instruction only when the degree of motion of the anti-counterfeit bluetooth transmission device exceeds the degree of motion threshold for m time periods (e.g., 10 seconds), and similarly, the processor sends the second instruction only when the degree of motion is below the preset degree of rest threshold for n time periods (e.g., 20 seconds).
On the basis of the above embodiment, the processor is further configured to:
sending a third instruction according to the fact that the duration time of the movement degree lower than the preset static degree threshold value after the second instruction is sent exceeds a preset first time threshold value;
the signal sending module is further configured to:
and entering a dormant state according to the third instruction and sending a heartbeat packet according to a preset frequency.
It should be noted that, if the quiescent time of the anti-counterfeit bluetooth sending device exceeds the preset first time threshold, the anti-counterfeit bluetooth sending device is considered to be in the quiescent state again, and at this time, in order to save electric power, the anti-counterfeit bluetooth sending device will send a heartbeat packet, and the purpose of sending the heartbeat packet is to make the ibeacon receiving device know that the anti-counterfeit bluetooth sending device is still in the connected state, so that the data content in the heartbeat packet may only include the unique identifier of the anti-counterfeit bluetooth sending device, and thus, the energy can be saved to the maximum extent. It should be noted that the dynamic and static detection module does not enter the dormant state, and still detects whether the anti-counterfeiting Bluetooth sending equipment moves or not at all times, and sends a message to the processor when the anti-counterfeiting Bluetooth sending equipment moves.
On the basis of the above embodiment, the anti-counterfeiting bluetooth sending device of the embodiment further comprises a clarinet switch; when the reed switch is in the magnetic field range, the reed switch is closed to wake up the label (similar to a sleep wake-up key of a mobile phone, the mobile phone is a physical key, and the physical key is considered as a magnetic key);
and the processor is also used for sending a third instruction after the anti-counterfeiting Bluetooth sending equipment is started. That is to say, when the anti-fake bluetooth transmitting device is enabled, the signal transmitting module first enters a sleep state, and maintains the connection with the bluetooth receiving device with extremely low power.
On the basis of the above embodiment, the processor is further configured to use a specific byte in the bluetooth signal to be sent as a decryption key, and encrypt the bluetooth signal to be sent according to an AES encryption algorithm.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
