[0002] With the development of science and technology and social progress, people's demand for leisure and entertainment is growing. For this reason, professional electronic game machines, claw machines and other unattended game equipment came into being. Although these devices are easy to put into operation, they usually require exchanged coins for coin-operated use, which gives criminals an opportunity to use counterfeit coins to commit illegal infringements, thereby damaging the interests of operators. In response to this problem, there are many coin anti-counterfeiting products on the market. However, the existing coin anti-counterfeiting products are prone to errors when identifying coins due to their simple structure, and their anti-counterfeiting means are single. Therefore, the existing coin anti-counterfeiting products cannot meet the actual anti-counterfeiting requirements, and a new coin anti-counterfeiting product is urgently needed to meet market demand.

DETAILED DESCRIPTION

[0055] In the field of coin anti-counterfeiting technology, there is currently a token identification device on the market (as shown in patent CN102110330A). The device is provided with a token channel, and a plurality of optical sensors arranged linearly are provided in the token channel. When the token enters the token channel and rolls in the token channel, the corresponding optical sensors among the plurality of optical sensors respectively identify the first start hole, the second start hole, the first sensing hole and the second sensing hole of the token, so as to judge the authenticity of the token according to the identification result. Although the device has a strong targeted and exclusive identification ability when identifying the token with the first start hole, the second start hole, the first sensing hole and the second sensing hole, the defect of the device is that when the optical sensor cannot be aligned with the first start hole, the second start hole, the first sensing hole or the second sensing hole, the device will not be able to identify any of the first start hole, the second start hole, the first sensing hole or the second sensing hole of the token, so that the device determines that the token is a fake token, but the token is obviously a real token. This situation shows that the identification process of the device is wrong, and the real token is identified as a fake token. In view of the problems existing in the existing token recognition devices, the present application provides the following embodiments to improve the coin anti-counterfeiting technology.

[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0058] See also Figure 1 and Figure 2 The present application provides an embodiment, which provides a coin identification device for identifying coins.

[0059] The coin identification device of this embodiment includes a coin selector 1 and a controller 2. The coin selector 1 includes a detection channel 11. The detection channel 11 includes a coin input port 101, a first coin output port 102 and a second coin output port 103. A screening device 111 is provided in the detection channel 11.

[0060] The controller 2 includes a data storage module 22 and a detection module 21 . The detection module 21 includes at least one color sensor component 210 .

[0061] The color sensor assembly 210 is disposed on the inner wall of the detection channel 11 , and is used to detect the coin when the coin passes through the detection channel 11 to obtain the color characteristics of the coin.

[0062] The controller 2 is connected to the screening device 111, and is used to compare the color feature with each preset feature stored in the data storage module 22. If the color feature is the same as any preset feature, the coin is determined to be a target coin, and the screening device 111 is controlled to output the target coin through the first coin output port 102. If the color feature is different from each preset feature, the coin is determined to be a non-target coin, and the screening device 111 is controlled to output the non-target coin through the second coin output port 103.

[0063] In this embodiment, the user inserts a coin into the coin selector 1 through the coin inlet 101. The coin inserted by the user is detected by the color sensor component 210 of the detection module 21 to obtain the color characteristics of the coin. Then, the detection module 21 transmits the color characteristics to the controller 2. Next, the controller obtains the preset characteristics from the data storage module 22 and compares the color characteristics. If the comparison result is that the two are the same, the coin is determined to be the target coin and the coin is output through the first coin outlet 102. If the comparison result is that the two are different, the controller 2 obtains the next preset characteristic from the data storage module 22 and compares it with the color characteristic until one of the preset characteristics is the same as the color characteristic, then the coin is determined to be the target coin and the coin is output through the first coin outlet 102; if the color characteristic is different from each preset characteristic, the coin is determined to be a non-target coin and the coin is output through the second coin outlet 103.

[0064] In this embodiment, the data storage module 22 can store multiple preset features. By detecting and obtaining the color features of multiple different coins entering from the coin inlet, and comparing the color features one by one with the multiple preset features stored in the data storage module 22, it is possible to determine whether multiple different coins are genuine or counterfeit coins, thereby realizing the recognition function of multiple coins and improving the ability to distinguish the authenticity of coins.

[0065] See also Figure 3 In some embodiments, the detection channel 11 of the coin recognition device is divided into a plurality of detection sections 112, each detection section 112 includes at least one color sensor component 210; the color sensor component 210 of each detection section 112 is used to detect one of the color areas of the coin to obtain the corresponding color feature.

[0066] The controller 2 is used to generate a combined color feature based on the multiple corresponding color features when multiple corresponding color features are obtained, and to compare the combined color feature with each preset feature stored in the data storage module 22. If the combined color feature is the same as any one of the preset features, the coin is determined to be a target coin, and the screening device 111 is controlled to output the target coin through the first coin output port 102. If the combined color feature is different from each preset feature, the coin is determined to be a non-target coin, and the screening device 111 is controlled to output the non-target coin through the second coin output port 103.

[0067] It can be understood that the color feature can be a code, each code represents a color, and the combined color feature generated by multiple color features is a combined code group, and each code in the code group represents a color.

[0068] In a specific embodiment, if there are multiple rings of different colors on one of the surfaces of the coin entering from the coin inlet 101, after the coin enters the detection channel 11, when the coin passes through one of the detection sections 112, the color sensor component 210 in the detection section 112 can detect a color feature from one of the rings on the coin; when the coin passes through multiple detection sections 112, each ring on the coin is in the corresponding detection section 112, and the color sensor component 210 in each detection section 112 can detect the corresponding color feature from the corresponding ring. When the coin moves in the detection channel 11, when the controller 2 obtains multiple color features of different colors from the multiple color sensor components 210, the controller 2 generates a combined color feature based on the multiple color features, and compares the combined color feature with the preset feature.

[0069] It is understood that in some embodiments, the detection channel 11 is divided into a plurality of detection segments 112 based on the length of the detection channel 11. For example, the detection channel 11 is divided into five detection segments 112, and each detection segment 112 is provided with a color sensor assembly 210. Assuming that there are two rings of different colors on a coin, when the coin moves in the detection channel 11, any two of the five color sensor assemblies 210 detect two rings of different colors respectively, and it can be recognized that the coin has two rings of different colors. It is understood that the more detection segments 112 are divided in the detection channel 11, the higher the recognition accuracy, and the more rings of different colors that can be recognized.

[0070] In other embodiments, multiple color sensor components 210 may be arranged in the detection section 112 based on the diameter of the detection channel 11. For example, the diameter of the detection channel 11 is the same as the diameter of the coin. When the coin passes through the detection section 112, the circular rings of different colors arranged and distributed based on the diameter of the coin correspond one-to-one with the multiple color sensor components 210 arranged and distributed based on the diameter of the detection channel 11 in the detection section 112. Each color sensor component 210 identifies the color of the corresponding circular ring to obtain multiple color features.

[0071] See also Figure 4 In some embodiments, the color sensor assembly 210 of the coin recognition device includes a first color sensor 211 and a second color sensor 212; the first color sensor 211 is located on one side of the inner wall of the detection channel 11, and the second color sensor 212 is located on the other side of the inner wall of the detection channel 11 opposite to the second color sensor 212; the first color sensor 211 is used to obtain the color characteristics of one surface of the coin when the coin enters the detection channel 11 through the coin inlet 101; the second color sensor 212 is used to obtain the color characteristics of another surface of the coin when the coin enters the detection channel 11 through the coin inlet 101.

[0072] In this embodiment, when the front and back sides of the coin entering the detection channel 11 from the coin inlet 101 have color areas, the color feature of the front side (back side) of the coin is obtained as the first color feature by the first color sensor 211, and the color feature of the back side (front side) of the coin is obtained as the second color feature by the second color sensor 212. If the first color feature is the same as the second color feature, the first color feature (second color feature) is compared with the preset feature by the controller 2. If the first color feature is different from the second color feature, the controller 2 generates a combined color feature based on the first color feature and the second color feature, and compares the combined color feature with the preset feature.

[0073] See also Figure 5 In some embodiments, the detection module 21 of the coin identification device further includes at least one detection component 220; the detection component 220 is located on the inner wall of the detection channel 11; the detection component 220 is used to detect the coin when the coin passes through the detection channel 11 to obtain the pattern characteristics of the coin.

[0074] The controller 2 is used to generate a combination feature based on the pattern feature and the color feature when the color feature and the pattern feature are acquired, and compare the combination feature with each preset feature stored in the data storage module 22. If the combination feature is the same as any preset feature, the coin is determined to be a target coin, and the screening device 111 is controlled to output the target coin through the first coin output port 102. If the combination feature is different from each preset feature, the coin is determined to be a non-target coin, and the screening device 111 is controlled to output the non-target coin through the second coin output port 103.

[0075] Optionally, in some embodiments, the detection component 220 is a camera device.

[0076] Optionally, in some embodiments, the detection component 220 of the coin identification device includes a signal transmitter 221 and a signal receiver 222; the signal transmitter 221 is located on one side of the inner wall of the detection channel 11, and the signal receiver 222 is located on the other side of the inner wall of the detection channel 11 opposite to the signal transmitter 221; the signal transmitter 221 is used to send a signal to the signal receiver 222; the signal receiver 222 is used to obtain a signal passing through the coin when the coin enters the detection channel 11 through the coin inlet 101, and obtain the pattern characteristics of the coin based on the signal passing through the coin.

[0077] Optionally, in some embodiments, the signal transmitter 221 is a laser transmitter, and the signal receiver 222 is a light sensor.

[0078] Optionally, in some embodiments, the signal transmitter 221 is an optical signal transmitter, which includes a plurality of light sources, and the plurality of light sources form a matrix; the signal receiver 222 is an optical sensor.

[0079] See also Figure 6 In some embodiments, the detection module 21 of the coin identification device also includes an initial detection component; the initial detection component is located on the inner wall of the detection channel 11 near the coin inlet 101; the initial detection component includes an initial signal transmitter 231 and an initial signal receiver 232; the initial signal transmitter 231 is located on one side of the inner wall of the detection channel 11, and the initial signal receiver 232 is located on the other side of the inner wall of the detection channel 11 opposite to the initial signal transmitter 221; the initial signal transmitter 231 is used to send an initial signal to the initial signal receiver 232; the initial signal receiver 232 is used to send a start work instruction to the color sensor component 210 and the detection component 220 through the controller 2 when the initial signal is not received.

[0080] In a specific embodiment, when a coin without a perforation enters the detection channel 11 through the coin inlet 101, first, the coin passes through the initial signal transmitter 231 and the initial signal receiver 232. When the coin passes through the initial signal transmitter 231 and the initial signal receiver 232, the initial signal transmitter 231 and the initial signal receiver 232 are respectively located on the inner walls of the detection channel 11 on both sides, and the coin passes between the inner walls on both sides. Since both counterfeit coins and real coins have a partial area blocking the initial signal sent from the initial signal transmitter 231 to the initial signal receiver 232, therefore, when the initial signal receiver 232 cannot receive the signal sent by the initial signal transmitter 231, the controller 2 can determine that there is a coin in the detection channel 11, and at this time, the controller 2 sends a start-up instruction to the color sensor component 210 and the detection component 220. After receiving the start-up instruction, the color sensor component 210 and the detection component 220 start and prepare to detect the coin.
