Description

Technical Field

[0001] This invention relates to the technical field of intelligent anti-cheating detection equipment for mahjong machines, specifically to a comprehensive anti-cheating detection device and method for mahjong machines. Background Technology

[0002] Automatic mahjong machines are widely used in entertainment venues and homes, leading to increasingly diverse cheating methods. Currently, common cheating methods mainly fall into two categories:

[0003] The first type involves concealing electronic modification components inside the mahjong machine. This includes installing a remote-controlled dice module inside the control panel, adding a cheating circuit board under the aluminum-plastic composite panel or tabletop, and hiding a wireless receiver module and modified wiring within the plastic frame cavity. These modifications control the dice rolls via remote control or program, or identify card information through sensors, thereby achieving the purpose of cheating.

[0004] The second type involves installing card recognition cheating devices along the shuffling and card-carrying paths. For example, electronic card recognition probes, program sensing modules, or cheating triggering elements are privately installed on the card suction wheel, conveyor trough, machine head, etc., and used with specially made program mahjong tiles or chip sensing tiles to read or mark the information of each mahjong tile during the shuffling and conveying process.

[0005] Existing anti-cheating detection devices have the following main shortcomings:

[0006] The detection range is limited to the static area of ​​the machine body, and only scans and inspects fixed parts such as the control panel and table. It cannot cover dynamic card movement links such as the shuffling barrel, card suction wheel, conveyor trough, machine head, card pushing track, and card lifting outlet.

[0007] Lacking the ability to scan and recognize mahjong tiles in motion, it cannot distinguish between ordinary mahjong tiles and those with programmed chips;

[0008] Unable to detect card recognition sensors or other cheating electronic components added later to the card-playing mechanism;

[0009] Static detection is easily circumvented by cheaters, who can bypass existing detection devices by engaging in cheating behavior along the dynamic card-playing path.

[0010] Therefore, existing technologies cannot provide comprehensive and effective anti-cheating protection for fully automatic mahjong machines. Summary of the Invention

[0011] The technical problem to be solved by this invention is that the static detection is incomplete and the dynamic card-playing link protection of the shuffling is missing in the prior art.

[0012] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a mahjong machine full-area anti-cheating detection device, comprising a chip body, wherein the chip body includes a main control processing module, an electromagnetic induction detection unit, a wireless signal detection unit, a high-frequency pulse detection unit, an illegal chip identification unit, a line abnormality detection unit, a dynamic trajectory scanning unit, an audible and visual alarm unit, and a voltage stabilizing power supply unit;

[0013] It also includes: four static areas of the fuselage and a dynamic trajectory area for shuffling and playing cards;

[0014] The four main static areas of the device are the control panel, aluminum-plastic composite panel, tabletop panel and plastic frame, and the chip body can be detachably installed inside the control panel;

[0015] The top of the internal cavity of the control panel is provided with a mounting groove for the chip body to be inserted.

[0016] The shuffling and card-moving dynamic trajectory area includes a shuffling barrel, suction wheels, conveyor trough, machine head, card-pushing track, and card-lifting panel;

[0017] The electromagnetic induction detection unit, wireless signal detection unit, high-frequency pulse detection unit, illegal chip identification unit, and circuit anomaly detection unit are used to detect the four static areas of the mahjong machine.

[0018] The dynamic trajectory scanning unit is used to detect the dynamic trajectory area of ​​shuffling and moving tiles in the mahjong machine.

[0019] The main control processing module receives the detection signals from each detection unit and controls the audible and visual alarm unit to sound an alarm when it determines that there are cheating characteristic signals.

[0020] As an improvement, the control panel includes an outer surface, an internal cavity, a dice box, and buttons.

[0021] As an improvement, the aluminum composite panel includes an upper surface of the entire panel, a lower surface of the entire panel, the edge of the panel, and a cavity in the interlayer.

[0022] As an improvement, the countertop panel is attached to the entire upper surface of the aluminum composite panel.

[0023] As an improvement, the entire plastic frame includes the outer surface, inner sidewall, frame cavity, splicing gap, and corners.

[0024] As an improvement, the high-frequency pulse detection unit is used to collect and identify encrypted pulse sensing signals of program mahjong tiles or chip cheating tiles; the dynamic trajectory scanning unit continuously scans the shuffling barrel, suction wheel, conveying trough, machine head, push track and lifting panel outlet after the shuffling is started.

[0025] As an improvement, the illegal chip identification unit has built-in original factory reference electrical parameter comparison logic to distinguish original electronic components from retrofitted non-original electronic components.

[0026] A method for detecting cheating across the entire mahjong machine includes the following steps:

[0027] S1. Equipment standby state: The electromagnetic induction detection unit, wireless signal detection unit, high-frequency pulse detection unit, illegal chip identification unit and circuit abnormality detection unit perform full-area static scanning of the four main body areas of the control panel, aluminum-plastic panel, tabletop panel and plastic frame to collect electromagnetic signals, wireless signals, pulse signals, chip identification signals and circuit signals.

[0028] S2. After the mahjong machine starts shuffling, it automatically starts dynamic trajectory scanning: the dynamic trajectory scanning unit continuously scans the inside of the shuffling barrel, the suction wheel, the conveying groove, the machine head, the push track, and the outlet of the lifting panel to track the entire movement of each mahjong tile.

[0029] S3. Collect the program pulse signal and chip encryption signal of the sports mahjong tiles; at the same time, collect the position signals of the tile suction wheel, conveyor groove and machine head to determine whether there are unauthorized electronic tile recognition components, program sensing components or cheating triggering components.

[0030] S4, the intelligent main control processing module compares all collected signals with the original factory benchmark parameters of the mahjong machine to distinguish between the original normal electrical signals and the cheating and modification signals.

[0031] S5. When cheating features are detected at any position in the four static areas or the dynamic card-playing link of the shuffling, it is determined to be cheating, triggering the sound and light alarm unit to issue a sound and light alarm and lock the prompt.

[0032] S6. The equipment continuously executes steps S1 to S5 in a loop to continuously protect against cheating.

[0033] As an improvement, in step S3, the pulse signal collected by the high-frequency pulse detection unit includes the encrypted pulse sensing signal of the program mahjong tiles or the chip cheating tiles; the dynamic trajectory scanning unit maintains uninterrupted scanning throughout the shuffling process until the shuffling is completed.

[0034] The advantages of this invention compared to the prior art are:

[0035] This invention simultaneously protects the four static modification areas of the machine body and the complete dynamic card-moving link of the shuffling and conveying system, blocking two types of cheating methods—concealed modification of the machine body and card-moving path modification for card recognition cheating, thus eliminating the biggest loophole in existing anti-cheating detection devices.

[0036] This invention can detect static modified components such as circuit boards and remote-controlled dice hidden in the machine casing interlayer and gaps, as well as card-recognition cheating devices added to the card suction wheel, conveyor groove, and machine head. It can also identify chip-programmed mahjong tiles that flow through the machine, achieving all-round three-dimensional detection.

[0037] The present invention provides complete protection, including the control panel, aluminum-plastic composite panel, tabletop panel, plastic frame, shuffling bucket, suction wheel, conveying trough, machine head, pusher track, and lifting panel, forming a comprehensive protection without blind spots.

[0038] This invention adopts an integrated chip design, which is simple in structure and can be detachably installed inside the operation panel through the mounting slot. It is easy to install, has good adaptability, and is suitable for mass production. Attached Figure Description

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] As attached Figure 2 Appendix Figure 3 and attached Figure 4 As shown, a mahjong machine full-area anti-cheating detection device includes a chip body 11, which includes a main control processing module 1101, an electromagnetic induction detection unit 1102, a wireless signal detection unit 1103, a high-frequency pulse detection unit 1104, an illegal chip identification unit 1105, a line abnormality detection unit 1106, a dynamic trajectory scanning unit 1107, an audible and visual alarm unit 1108, and a voltage stabilizing power supply unit 1109.

[0046] It also includes: four static areas of the fuselage and a dynamic trajectory area for shuffling and playing cards;

[0047] The four main static areas of the machine body are the control panel 1, aluminum-plastic panel 2, tabletop panel 3, and plastic frame 4.

[0048] The control panel 1 includes an outer surface, an internal cavity, a dice box, and buttons. The top of the internal cavity of the control panel 1 has a mounting groove 101 for inserting a chip body 11. The chip body 11 is bolted into the mounting groove. The chip body 11 is detachably installed inside the control panel 1. The aluminum-plastic composite panel 2 includes an upper surface, a lower surface, edges, and a cavity. The tabletop panel 3 is attached to the upper surface of the aluminum-plastic composite panel 2. The plastic frame 4 includes its outer surface, inner wall, frame cavity, seams, and corners.

[0049] The shuffling and card-moving dynamic trajectory area includes a shuffling barrel 5, a card-suction wheel 6, a conveying trough 7, a machine head 8, a card-pushing track 9, and a card-lifting panel 10;

[0050] The electromagnetic induction detection unit 1102, wireless signal detection unit 1103, high-frequency pulse detection unit 1104, illegal chip identification unit 1105, and circuit abnormality detection unit 1106 are used to detect the four static areas of the mahjong machine body; the high-frequency pulse detection unit 1104 is used to collect and identify encrypted pulse induction signals of program mahjong tiles or chip cheating tiles.

[0051] The dynamic trajectory scanning unit 1107 is used to detect the dynamic trajectory area of ​​the mahjong machine's shuffling and card movement. After the shuffling is started, the dynamic trajectory scanning unit 1107 continuously scans the shuffling barrel 5, the suction wheel 6, the conveying trough 7, the machine head 8, the card pushing track 9, and the card lifting panel 10 outlet.

[0052] The main control processing module 1101 receives the detection signals from each detection unit and controls the audible and visual alarm unit 1108 to sound an alarm when it determines that there is a cheating feature signal.

[0053] The illegal chip identification unit 1105 has built-in original factory reference electrical parameter comparison logic, which is used to distinguish original factory electronic components from aftermarket non-original factory electronic components.

[0054] In conjunction with the above-described device structure, this embodiment also provides a method for detecting cheating across the entire mahjong machine, as shown in the attached figure. Figure 1 As shown, the specific execution steps are as follows:

[0055] S1. Device standby full-area static scan:

[0056] After the mahjong machine is powered on, the chip body 11 is powered on and started by the voltage regulator unit 1109, entering a continuous standby detection state. In this state, the main control processing module 1101 controls the electromagnetic induction detection unit 1102, the wireless signal detection unit 1103, the high-frequency pulse detection unit 1104, the illegal chip identification unit 1105, and the circuit abnormality detection unit 1106 to work together to continuously scan the four static body areas: the internal cavity of the operation panel 1 and the dice box area, the upper and lower surfaces of the aluminum-plastic board 2 and the interlayer cavity, the area below the adhesive layer of the table panel 3, and the outer wall and inner cavity and splicing gap of the plastic frame 4. Each detection unit collects electromagnetic field strength data, wireless communication frequency band signals, high-frequency pulse characteristics, electronic component electrical parameters, and circuit impedance distribution in the corresponding area, and transmits the collected raw signals to the main control processing module 1101 in real time for buffering and preprocessing.

[0057] S2. Shuffle Start-up Dynamic Trajectory Full Scan:

[0058] When the mahjong machine control system issues a shuffling start command, the shuffling drum 5 begins to rotate. The mahjong tiles, after being shuffled, are lifted by the suction wheel 6 and placed into the conveyor trough 7. Simultaneously, the main control processing module 1101 automatically activates the dynamic trajectory scanning unit 1107 upon detecting the shuffling action signal. The dynamic trajectory scanning unit 1107 performs a continuous, traversal scan along the entire shuffling path, starting from inside the shuffling drum 5, passing through the suction area of ​​the suction wheel 6, the conveyor channel of the conveyor trough 7, the stacking position of the machine head 8, the pushing path of the pusher track 9, and finally to the exit position of the lifting panel 10, according to a preset scanning frequency. Throughout the entire movement of each mahjong tile from entering the shuffling drum 5 to finally reaching the exit of the lifting panel 10, the dynamic trajectory scanning unit 1107 continuously tracks its position changes and signal characteristics, ensuring no omissions or blind spots.

[0059] S3. Collection of cheating signals from sports cards and card-playing mechanisms:

[0060] During dynamic scanning, the high-frequency pulse detection unit 1104 works in conjunction with the dynamic trajectory scanning unit 1107. When the mahjong tiles flow through the suction area of ​​the suction wheel 6, the channel of the conveyor trough 7, or the stacking position of the machine head 8, the high-frequency pulse detection unit 1104 emits a high-frequency detection pulse at close range to each tile and receives the echo signal, collecting any program pulse codes or chip encryption sensing signals that may be carried within them. If a mahjong tile contains a cheating encryption pulse chip, it will radiate a pulse response signal of a specific frequency. The high-frequency pulse detection unit 1104 can accurately capture this signal and mark the corresponding tile position. At the same time, the electromagnetic induction detection unit 1102 and the circuit abnormality detection unit 1106 synchronously monitor the area around the suction wheel 6, the side wall of the conveyor trough 7, and the tile pushing arm of the machine head 8, collecting abnormal electromagnetic field signals and circuit load change signals for any unauthorized electronic tile recognition coils, micro-program induction probes, or cheating trigger switches. All collected data is transmitted back to the main control processing module 1101 in real time.

[0061] S4. Signal Comparison and Cheating Detection:

[0062] After receiving all the acquired signals from the detection units in the static area and the dynamic trajectory scanning unit 1107, the main control processing module 1101 retrieves the original factory benchmark parameter database of the mahjong machine stored internally. This database contains the standard electromagnetic background values ​​of each static area when the mahjong machine leaves the factory, the idle noise floor of the wireless frequency band, the electrical parameter range of normal electronic components, the basic impulse response characteristics of ordinary mahjong tiles, and the standard sensor feedback signal models of each position of the tile-playing mechanism. The illegal chip identification unit 1105 compares the electrical parameters of each electronic component acquired in real time with the original factory parameters one by one according to the built-in original factory benchmark electrical parameter comparison logic. The main control processing module 1101 integrates the comparison results and, through difference analysis, feature matching, and abnormal pattern recognition algorithms, distinguishes between the original normal electrical signals and the cheating signals of externally added or modified components, and generates a difference report.

[0063] S5. Cheating Detection and Alarm Lockout:

[0064] The main control processing module 1101 makes a logical decision based on the discrepancy report. If any static cheating characteristics such as abnormal electromagnetic sources, non-original wireless transmission modules, illegal chips, or unauthorized wiring are found in any of the four static areas—operation panel 1, aluminum-plastic panel 2, tabletop panel 3, and plastic frame 4—or if any dynamic cheating characteristics such as added card recognition sensors, program triggering devices, or program pulse mahjong tiles or chip-encrypted mahjong tiles are detected at any position in the dynamic card-playing link, the main control processing module 1101 immediately determines that cheating is occurring. After confirming cheating, the main control processing module 1101 sends a trigger command to the audible and visual alarm unit 1108 within a very short time. The audible and visual alarm unit 1108 then emits a high-volume buzzer alarm and a high-frequency flashing light prompt. At the same time, the main control processing module 1101 sends a lock signal to the mahjong machine's main control circuit, forcing the mahjong machine to interrupt the current card-playing or card-playing process and enter an inoperable locked state. The lock can only be released after a professional manager performs a reset operation using a dedicated unlocking tool or key.

[0065] S6, Continuous Cyclic Protection:

[0066] After completing a full static scan and dynamic card-playing detection cycle, if the mahjong machine remains in standby or a new round of shuffling, the chip body 11 automatically repeats steps S1 to S5. This means that regardless of whether the device is in standby or shuffling mode, it maintains continuous, multi-dimensional detection across the entire domain, forming a closed-loop protection system from static concealed modifications to dynamic card-playing cheating, effectively preventing cheaters from exploiting detection gaps to commit fraud.

[0067] It should be further explained that during the execution of step S3, the pulse signal collected by the high-frequency pulse detection unit 1104 explicitly includes the encrypted pulse sensing signal of the program mahjong tiles or chip cheating tiles; the dynamic trajectory scanning unit 1107 enters the uninterrupted scanning mode from the moment the shuffle starts, until the shuffle and play are all completed and reset, during which the scanning operation is not interrupted and no play is skipped.

[0068] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
