Description

Technical Field

[0001] This invention belongs to the field of monitoring and anti-tampering technology, specifically relating to an alarm system and detection method for cigarette tampering. Background Technology

[0002] Cigarettes, especially high-end and expensive brands, are a relatively valuable commodity in convenience stores and supermarkets. Theft or substitution of cigarettes can cause significant losses. Cigarette counters are usually located in the cashier area, making theft less likely. However, criminals often use substitution to steal cigarettes: when receiving a cigarette from the shopkeeper, they feign asking the cashier to get another brand while turning their backs to the shopkeeper. The shopkeeper then hides the cigarette in their bag or hands it to an accomplice, taking a counterfeit cigarette of the same brand. When the cashier turns around, the counterfeit cigarette is returned. Because it's difficult to distinguish between real and counterfeit cigarettes with the naked eye, the cashier often doesn't notice the substitution and is thus cheated. Summary of the Invention

[0003] This invention provides a cigarette swapping alarm system and detection method to solve the above-mentioned technical problems.

[0004] The technical solution adopted in this invention is as follows:

[0005] A cigarette swapping alarm system includes: an information acquisition module for collecting information on the actions of a person taking cigarettes; a comparison module including a comparison unit and a database, wherein the comparison unit acquires the action information and compares it with a pre-stored cigarette swapping action database in the database to determine whether the person taking cigarettes has engaged in cigarette swapping behavior; the cigarette swapping action database includes several swapping posture information based on the 95th percentile of human beings when swapping cigarettes; when the action information matches at least one swapping posture information in the cigarette swapping action database, the comparison unit determines that the person taking cigarettes has engaged in cigarette swapping behavior and issues a confirmation of swapping information; and an alert module, which acquires the confirmation of swapping information and sends an alert signal through a terminal.

[0006] The cigarette swapping alarm system in this application also includes the following additional technical features:

[0007] The cigarette swapping behavior action database includes a dynamic information database, which includes at least a first swapping posture information, a second swapping posture information, and a third swapping posture information. The first swapping posture information is the posture of holding a cigarette; the second swapping posture information is the posture of placing a cigarette in the storage space carried by the person taking the cigarette to hide it, or the posture of passing a cigarette from the person holding the cigarette to another person; the third swapping posture information is the posture of retrieving a cigarette from the storage space carried by the person taking the cigarette, or the posture of receiving a cigarette passed by another person. When the behavior action information simultaneously matches the first swapping posture information, the second swapping posture information, and the third swapping posture information, the comparison unit determines that the person taking the cigarette has swapped cigarettes and issues a confirmation of the swapping behavior.

[0008] The cigarette-switching behavior action database includes a static information database, which includes several special gesture information. The special gesture information is based on the static posture of the 95th percentile human being when communicating with other people. The special gesture information includes at least a fourth and a fifth cigarette-switching posture. The fourth cigarette-switching posture is when the person holding the cigarette is in a hand-behind-the-back posture, and the fifth cigarette-switching posture is when the person holding the cigarette is in a raised-hand posture. When the behavior action information matches the fourth or fifth cigarette-switching posture information, the comparison unit determines that the person holding the cigarette has committed cigarette-switching behavior and issues a confirmation of the cigarette-switching behavior.

[0009] The warning signals include light signals and sound signals.

[0010] The warning module includes a light source facing the salesperson to emit the light signal and a sound source capable of emitting the sound signal.

[0011] The database contains a facial information database, which contains facial image information of the salesperson. After receiving the behavior information, the comparison unit compares the facial information in the behavior information with the facial image information. If the result is that the facial information corresponds to the facial image information, the cigarette swapping behavior is not judged.

[0012] A method for detecting cigarette swapping behavior is also provided, applied to the cigarette swapping behavior alarm system described above. The detection method comprises the following steps: a person receiving cigarettes; an information acquisition module collects and sends the behavioral action information of the person receiving cigarettes within a preset time range to a comparison module; the comparison module receives the behavioral action information and compares it with the swapping posture information in the swapping behavior action database through a comparison unit, and determines whether the person receiving cigarettes has swapped cigarettes. If so, the comparison module sends a confirmation of the swapping behavior; after obtaining the confirmation of the swapping behavior, the warning module sends a warning signal through the terminal.

[0013] Due to the adoption of the above technical solution, the beneficial effects achieved by this invention are as follows:

[0014] 1. This application collects the action information of the person taking cigarettes through an information acquisition module and sets up a comparison module to compare and analyze the action information. The comparison module includes a comparison unit and a database. By comparing the action information with the swapping posture information based on the 95th percentile of human body when swapping cigarettes, the system determines that the person taking cigarettes has swapped cigarettes if the action information matches at least one swapping posture information in the swapping behavior action database. If the action information does not match any swapping posture information in the swapping behavior action database, the system determines that the person taking cigarettes has not swapped cigarettes. If the determination result is that swapping behavior has occurred, the comparison module sends swapping information to the warning module. After receiving the swapping information, the warning module sends a warning signal through the terminal, thereby alerting the salesperson. The alarm system provided by this application determines whether cigarette swapping behavior has occurred by recognizing the action information of the person taking cigarettes. It can accurately identify swapping behavior and alert the salesperson, prompting the salesperson to identify whether the cigarettes have been swapped, thereby reducing the economic losses of the cigarette salesperson.

[0015] 2. As a preferred embodiment of the present invention, the dynamic information database pre-stores first, second, and third information on the act of switching cigarettes. If a person taking cigarettes engages in switching cigarettes, their actions will necessarily match the first, second, and third information on the act of switching cigarettes. Therefore, if the actions of the person taking cigarettes match the first, second, and third information on the act of switching cigarettes, it is determined that a cigarette switching act has occurred. This effectively improves the accuracy of the determination and largely avoids identifying normal customers as people who switch cigarettes, thereby improving the customer's purchasing experience.

[0016] 3. In a preferred embodiment of the present invention, the database also includes a static information database, which contains special gesture information. When a person taking a cigarette cooperates with another person to switch cigarettes, they often communicate through gestures. By pre-storing special gesture information, including fourth and fifth switching posture information, in the static information database, when the comparison unit detects that the behavior of the person taking the cigarette matches the fourth or fifth switching posture information, it is determined that the person taking the cigarette has engaged in switching behavior. By setting up a static information database, the comparison range of the comparison module for the behavior information of the person taking the cigarette can be improved, thereby enhancing the accuracy of determining switching behavior.

In the drawings:

[0018] Figure 1 This is a schematic diagram of a cigarette swapping alarm system according to one embodiment of the present invention. Detailed Implementation

[0019] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0020] Many specific details are set forth in the following description to provide a thorough understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, embodiments of the invention and features thereof can be combined with each other.

[0021] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] like Figure 1As shown, a cigarette swapping alarm system includes: an information acquisition module for collecting information on the actions of a person taking cigarettes; a comparison module, including a comparison unit and a database, wherein the comparison unit acquires the action information and compares it with a pre-stored swapping action database in the database to determine whether the person taking cigarettes has engaged in cigarette swapping behavior; the swapping action database includes several swapping posture information based on the 95th percentile of human beings when swapping cigarettes; when the action information matches at least one swapping posture information in the swapping action database, the comparison unit determines that the person taking cigarettes has engaged in cigarette swapping behavior and issues a confirmation of swapping information; and an alert module, which acquires the confirmation of swapping information and sends an alert signal through a terminal.

[0023] This application collects the action information of the person taking cigarettes through an information acquisition module and sets up a comparison module to compare and analyze the action information. The comparison module includes a comparison unit and a database. By comparing the action information with the swapping posture information based on the 95th percentile of human body when swapping cigarettes, the system determines that the person taking cigarettes has swapped cigarettes if the action information matches at least one swapping posture information in the swapping behavior action database. If the action information does not match any swapping posture information in the swapping behavior action database, the system determines that the person taking cigarettes has not swapped cigarettes. If the determination result is that swapping behavior has occurred, the comparison module sends swapping information to the warning module. After receiving the swapping information, the warning module sends a warning signal through the terminal, thereby alerting the salesperson. The alarm system provided by this application determines whether cigarette swapping behavior has occurred by recognizing the action information of the person taking cigarettes. It can accurately identify swapping behavior and alert the salesperson, thereby prompting the salesperson to identify whether the cigarettes have been swapped, thus reducing the economic losses of the cigarette salesperson.

[0024] As a preferred embodiment of this application, such as Figure 1 As shown, the cigarette swapping behavior action database includes a dynamic information database. The dynamic information database includes at least a first swapping posture information, a second swapping posture information, and a third swapping posture information. The first swapping posture information is the posture of holding a cigarette. The second swapping posture information is the posture of placing a cigarette in the storage space carried by the person taking the cigarette to hide it, or the posture of passing a cigarette from the person holding the cigarette to another person. The third swapping posture information is the posture of retrieving a cigarette from the storage space carried by the person taking the cigarette, or the posture of receiving a cigarette passed by another person. When the behavior action information simultaneously matches the first swapping posture information, the second swapping posture information, and the third swapping posture information, the comparison unit determines that the person taking the cigarette has swapped cigarettes and issues a confirmation swapping message.

[0025] By pre-storing the first, second, and third cigarette-switching posture information in a dynamic information database, if a person taking cigarettes engages in cigarette-switching behavior, their actions will necessarily match all three postures simultaneously. Therefore, if the person's actions match all three postures, it is determined that cigarette-switching has occurred, effectively improving the accuracy of the judgment and largely avoiding misidentifying normal customers as cigarette-switching personnel, thereby enhancing the customer's purchasing experience.

[0026] In a preferred embodiment of this application, the cigarette-switching behavior action database includes a static information database, which includes several special gesture information. The special gesture information is based on the static posture of the 95th percentile human being when communicating with other people. The special gesture information includes at least a fourth cigarette-switching posture information and a fifth cigarette-switching posture information. The fourth cigarette-switching posture information is that the person taking the cigarette is in a hand-behind-the-back posture, and the fifth cigarette-switching posture information is that the person taking the cigarette is in a raised-hand posture. When the behavior action information matches the fourth or fifth cigarette-switching posture information, the comparison unit determines that the person taking the cigarette has committed cigarette-switching behavior and issues a confirmation of the cigarette-switching information.

[0027] When a person takes a cigarette and collaborates with another person to switch cigarettes, they often communicate through gestures. By pre-storing special gesture information, including fourth and fifth switching gesture information, in a static information database, when the comparison unit detects that the person taking the cigarette's actions match the fourth or fifth switching gesture information, it determines that the person taking the cigarette has engaged in switching. By setting up a static information database, the comparison module can expand the comparison range of the person taking the cigarette's actions and improve the accuracy of determining switching behavior.

[0028] In a preferred embodiment of this application, the warning signal includes a light signal and an audio signal. When the warning module receives the information about the product swap, it sends a light signal and an audio signal through the terminal to provide a warning to the sales staff. By using both audio and visual warning methods, the sales staff are ensured to be aware of the product swap.

[0029] As a preferred embodiment of this implementation, such as Figure 1 As shown, the warning module includes a light source facing the salesperson to emit a light signal and a sound source capable of emitting a sound signal. Specifically, a spotlight can be used as the light source, and a speaker can be used as the sound source.

[0030] In a preferred embodiment of this application, a facial information database is pre-stored, containing facial image information of sales personnel. After receiving behavioral action information, the comparison unit compares the facial information in the behavioral action information with the facial image information. If the facial information matches the facial image information, the cigarette swapping behavior is not judged. Since sales personnel perform actions such as handling cigarettes during the sale, these actions may be identified by the comparison module as matching the swapping posture information in the behavioral action database, causing the warning module to send incorrect warning signals. By setting up a facial information database, the behavioral action information sent by the information collection module to the comparison module is first compared with the pre-stored facial image information in the facial information database. If the facial information matches the facial image information, the cigarette swapping behavior is not judged, thus preventing the comparison module from mistaking the sales personnel's actions for swapping behavior.

[0031] A method for detecting cigarette swapping is provided, applied to the cigarette swapping alarm system described above. The detection method comprises the following steps: a person receives cigarettes; an information acquisition module collects and sends the behavioral information of the person receiving the cigarettes within a preset time range to a comparison module; the comparison module receives the behavioral information and compares it with swapping posture information in a swapping behavior database using a comparison unit, determining whether the person receiving the cigarettes has swapped them. If so, the comparison module issues a confirmation of the swapping; and the warning module, upon receiving the confirmation, sends a warning signal through a terminal. This detection method can accurately detect cigarette swapping, significantly reducing the occurrence of cigarette swapping.
