Abstract
Description
Technical Field
[0001] The present application relates to the field of anti-theft technology, and in particular to an electronic anti-theft tag and a control method thereof. Background Art
[0002] Commodity anti-theft is an important part of shopping malls and supermarkets operations and warehouse storage. Especially with the rapid development of society and economy, there are more and more shopping malls and supermarkets, and their scale is getting bigger and bigger. Shopping malls and supermarkets must not only consider reducing labor costs and improving customer experience, but also solve the problem of commodity anti-theft. Anti-theft tags are currently the most commonly used anti-theft devices.
[0003] In the related art, a locking anti-theft tag is provided. This type of tag adopts a specific mechanical structure to form a locking device. The locking device and the anti-theft nail are used to fix the anti-theft tag on the commodity. Only with a corresponding magnetic opening tool can this type of anti-theft tag be opened. Customers cannot open the anti-theft tag with bare hands, thereby achieving the purpose of anti-theft. The locking device and the anti-theft nail need to be used in conjunction. The anti-theft nail is inserted into the lock cylinder of the locking device after passing through the commodity. The unlocking device (generally a magnet) at the counter is required to open the anti-theft tag and remove it from the commodity. If the commodity with the anti-theft tag is not checked out at the counter, when passing through the exit of the shopping mall or supermarket, the detection device at the exit of the shopping mall or supermarket will detect the chip or coil in the anti-theft tag, and the detection device will sound an alarm, ultimately achieving the purpose of anti-theft. The disadvantage of this anti-theft tag is that it does not have an absolutely safe anti-theft function. Since this type of anti-theft tag can be easily opened by any magnet, it can be opened by others with a magnet brought by themselves, making the anti-theft tag lose its anti-theft function. Moreover, this type of anti-theft tag requires anti-theft nails to pierce the product, which is not suitable for some products with special requirements, so its usage scenarios are limited.

[0049] like Figures 1 to 5 As shown, an embodiment of the present application provides an electronic anti-theft tag, including: a carrier 1, a controller 2, an air pressure sensor 3, an alarm 4 and a battery module 5. The carrier 1 can be a shell structure, such as a plastic shell. The controller 2 is arranged on the carrier 1, the air pressure sensor 3 is electrically connected to the controller 2, and the air pressure sensor 3 is used to monitor the air pressure signal in real time. The alarm 4 is arranged on the carrier 1, and the alarm 4 is electrically connected to the controller 2. The alarm 4 includes any one or more of a warning light 42, a buzzer 41 and a speaker. The battery module 5 is arranged on the carrier 1, and the battery module 5 is electrically connected to the controller 2. The battery module 5 is used to provide power to the controller 2, the air pressure sensor 3 and the alarm 4, etc. The air pressure sensor 3 is used to send the monitored air pressure signal to the controller 2, and the controller 2 is used to send an alarm instruction to the alarm 4 according to the air pressure signal, and control the alarm 4 to execute the alarm instruction.
[0050] When the electronic anti-theft tag provided by the present application is used, it is placed in a packaging bag together with the object, and the packaging bag needs to be vacuumed. When the packaging bag is damaged, the air pressure in the packaging bag will rise rapidly, and the air pressure sensor 3 will monitor the change of air pressure and send a signal to the controller 2, and the controller 2 controls the alarm 4 to sound an alarm. The electronic anti-theft tag of the present application has a simple structure and low cost, and can effectively achieve the purpose of anti-theft protection of objects.
[0051] The electronic anti-theft tag provided by the present application innovatively adopts the air pressure sensor 3, and cleverly uses the air pressure sensor 3 to sense the air pressure change to monitor whether the package is damaged. This anti-theft principle cannot or is difficult to be cracked, and can effectively achieve the purpose of anti-theft protection of objects.
[0052] In some possible implementations, the carrier 1 has a cavity, and the controller 2 and the battery module 5 are both arranged in the cavity, and the carrier 1 can protect the controller 2 and the battery module 5. The air pressure sensor 3 can be arranged in the cavity, and can also be effectively protected by the carrier 1. When the cavity is a sealed cavity, the air pressure sensor 3 can also be exposed to the outer surface of the carrier 1, so as to conveniently sense the air pressure changes in the packaging bag. For example, a recessed groove can be set on the surface of the carrier 1, and the air pressure sensor 3 can be set in the recessed groove. The air pressure sensor 3 does not protrude from the notch of the recessed groove to avoid being bumped by external structures.
[0053] In some possible implementations, the controller 2 includes a circuit board and a control module disposed on the circuit board, and the control module may be a chip, for example, the control module may be an MCU. The circuit board is located in the cavity, and the air pressure sensor 3 is disposed on the circuit board. The air pressure sensor 3 is integrated on the circuit board, which simplifies the assembly structure, and there is no need to separately assemble the air pressure sensor on the carrier 1.
[0054] In some possible implementations, the air pressure sensor 3 is disposed in the cavity, and the carrier 1 has a vent 11 connected to the cavity. In this implementation, the air pressure sensor 3 is disposed inside the carrier 1, and the air pressure sensor 3 is protected by the carrier 1, thereby extending the service life. At the same time, the carrier 1 is provided with a vent 11, which can connect the cavity with the outside world, so that the air pressure sensor 3 can smoothly monitor the air pressure changes in the outside world, thereby realizing accurate alarm.
[0055] In some possible implementations, a groove 12 is disposed on the outer wall of the carrier 1 , and the vent 11 includes a vent hole disposed on the bottom wall of the groove 12 , and the vent hole is connected to the cavity.
[0056] In this embodiment, by providing the groove 12 and providing the vent hole on the bottom wall of the groove 12, it is possible to avoid the packaging bag closing the vent hole during vacuuming, thereby affecting the accurate monitoring of the air pressure change by the air pressure sensor 3. After the packaging bag is vacuumed, the packaging bag will cover the groove 12, but will not directly cover the vent hole. As a result, the air pressure in the groove 12 is consistent with the air pressure value inside the carrier 1, and the air pressure sensor 3 can accurately and effectively monitor the change of the air pressure in the packaging bag.
[0057] In some possible implementations, such as Figure 1 As shown, the groove 12 extends along the carrier 1, and the groove 12 is an annular closed groove. The extension span of the groove 12 is large, and the matching area between the groove and the packaging bag is large. When any position of the packaging bag is damaged, the corresponding air pressure change is easy to occur at the groove 12, so that the air pressure sensor 3 can quickly sense the change of air pressure, so as to give an alarm in time.
[0058] In some possible embodiments, the electronic anti-theft tag includes a switch 6, which is located in the cavity and electrically connected to the controller 2. The carrier 1 has an operating hole 13 connected to the cavity, and the operating hole 13 is opened on the bottom wall of the groove 12.
[0059] The controller 2 includes a circuit board and a control module disposed on the circuit board. The switch 6 may be disposed on the circuit board. Figure 1 and Figure 3 As shown, the carrier 1 is provided with an operation hole 13, through which a professional tool can pass and contact the switch 6 to trigger the electronic anti-theft tag to start. The setting of the operation hole 13 is conducive to connecting the internal cavity of the carrier 1 with the external environment. The operation hole 13 is set on the bottom wall of the groove 12, which not only realizes a hidden setting, which is conducive to the complete and beautiful appearance of the carrier 1, but also prevents the packaging bag from closing the operation hole 13 when vacuuming, so that the air pressure sensor 3 in the cavity can accurately monitor the external air pressure value in real time.
[0060] In some possible embodiments, combined with Figure 2 and Figure 4 As shown, the carrier 1 includes two shells, and the edges of the shells are provided with notches 111. When the two shells are connected, the cavity is formed between the two shells, and the notches 111 of the two shells are connected to form the vent 11. The vent 11 does not need to be specially opened in the middle of the shell, but the notch 111 is provided on the edge of the shell. After the two shells are spliced, the two notches 111 enclose to form a vent.
[0061] In some possible implementations, the alarm 4 includes a warning light 42 disposed on a circuit board, the warning light 42 may be an LED light, a light hole is disposed on the housing, and the electronic anti-theft tag further includes a light guide column 8, the light guide column 8 is embedded in the light hole, and the light guide column 8 extends to the LED light. When the electronic anti-theft tag detects theft information, the LED light is controlled to light up or flash. There are obvious brightness and color changes on the light guide column 8, and the LED light can achieve the effect of sound and light alarm in conjunction with a buzzer 41 or a speaker.
[0062] The electronic anti-theft tag also includes a wireless receiving module, which is used to receive external signals to terminate the alarm program. The wireless receiving module can be a frequency element 7.
[0063] like Figure 5 As shown, the present application also provides a control method for an electronic anti-theft tag, including:
[0064] Step S1, the electronic anti-theft tag receives a power-on instruction;
[0065] In this step, the operator uses a professional tool to pass through the operating hole 13 and press against the switch 6 to trigger the electronic anti-theft tag to start up.
[0066] Step S2, the electronic anti-theft tag is turned on and obtains the ambient air pressure, and the electronic anti-theft tag sets a first air pressure value and a second air pressure value according to the ambient air pressure;
[0067] In this step, after the electronic anti-theft tag is turned on, it first monitors the ambient air pressure, that is, the atmospheric pressure. Due to different geographical locations, the atmospheric pressure has some deviations. The electronic anti-theft tag automatically sets the first air pressure value and the second air pressure value according to the local atmospheric pressure. The first air pressure value is the threshold for triggering the entry into the protection state (or defense mode). The second air pressure value is the threshold for triggering the alarm.
[0068] Step S3, the electronic anti-theft tag monitors the air pressure value in real time, and determines whether the air pressure value is lower than the first air pressure value. If the determination result is yes, proceed to step S4, otherwise proceed to step S3;
[0069] In this step, the operator puts the electronic anti-theft tag and the object (or commodity) into a packaging bag, and then evacuates the packaging bag so that the air pressure inside the packaging bag is much lower than the external atmospheric pressure.
[0070] In this step, if the air pressure value monitored by the electronic anti-theft tag is always lower than the first air pressure value, it is determined that the vacuuming operation is not performed or the vacuuming is not successful, so the electronic anti-theft tag does not enter the protection state (or defense mode).
[0071] Step S4, the electronic anti-theft tag controls the device to enter a protection state, the electronic anti-theft tag monitors the air pressure value in real time, and determines whether the air pressure value is higher than the second air pressure value. If the determination result is yes, the device proceeds to step S5, otherwise, the device proceeds to step S4;
[0072] When the air pressure value monitored by the electronic anti-theft tag is higher than the second air pressure value, it can be determined that the packaging bag is damaged and leaking, and there is a risk of the goods being stolen.
[0073] Step S5: The electronic anti-theft tag controls the alarm 4 to sound an alarm.
[0074] In some possible implementations, the first air pressure is obtained by multiplying the ambient air pressure by a first coefficient, and the second air pressure is obtained by multiplying the ambient air pressure by a second coefficient, wherein the first coefficient is less than the second coefficient. For example, the first coefficient may be 0.2 to 0.4, preferably 0.3. The second coefficient may be 0.7 to 0.9, preferably 0.8.
