Description

Technical Field

[0001] This invention relates to the fields of electronic amusement equipment and Internet of Things (IoT) communication technology, specifically to a remote coin acceptor and its control system and method. Background Technology

[0002] With the rapid development of IoT technology and mobile communication networks, the "cloud gaming" model, which connects traditional offline amusement equipment to the internet, has become a new trend in the entertainment industry. Remotely controlling physical amusement equipment through player interaction terminals (such as mobile apps) breaks geographical limitations, allowing users to experience the fun of amusement anytime, anywhere. Current remote amusement systems typically consist of front-end operating software, cloud servers, and offline physical terminal equipment, transmitting images via video streams and actions via control commands to achieve a closed loop of human-computer interaction.

[0003] Existing devices generally employ program-driven control logic, meaning that the success rate of grabbing depends heavily on the probability algorithm or grabbing force parameters preset by the backend system, rather than real physical laws. This artificial electronic control method leads to a lack of transparency and fairness in the game results, and users often feel distrusted by pseudo-random algorithms, which reduces the realism and psychological satisfaction of the game. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a remote coin acceptor and its control system and method, which solves the problem that existing devices generally use program-based control logic, resulting in a lack of transparency and fairness in game outcomes.

The outer wall of the threaded rod is rotatably connected to the inside of the rectangular slider. A second connecting block is threadedly connected to the outer wall of the threaded rod. A sliding rod is slidably connected to the inside of the second connecting block. Both ends of the sliding rod are fixedly connected to the outer wall of the rectangular slider. A coin box is fixedly connected to the inner wall of the second connecting block. A coin slot is provided on the outer wall of the coin box. An electromagnetic actuator is provided on the outer wall of the coin box.

[0007] Preferably, the control component includes a control panel, the outer wall of which is fixedly connected to the outer wall of the liquid container, an audio system is installed inside the control panel, control buttons are installed inside the control panel, and a joystick is installed inside the control panel.

[0008] Preferably, a control system for a remote coin acceptor includes a player interaction terminal, a cloud service platform, and a coin acceptor main control terminal connected sequentially via a communication network;

[0009] The player interaction terminal is equipped with a touch command generation module and a video display module; the video display module is used to receive and decode video stream data from the cloud service platform for real-time playback; the touch command generation module is used to respond to the user's touch operation, generate digital control signals containing displacement commands, coin insertion action trigger commands and audio switching commands containing coin acceptor coordinate information, and send the digital control signals to the cloud service platform;

[0010] The cloud service platform is configured with a signal routing and forwarding module and a streaming media distribution module.

[0016] Preferably, the communication transmission mode receiving the digital control signal and uploading the video data specifically includes the following steps:

[0017] A long TCP connection or UDP transmission channel is established and maintained with the cloud service platform through the network protocol stack, and heartbeat data packets are sent periodically to keep the link active.

[0018] When uploading the video data, the encoded video frame sequence output by the video acquisition module is obtained, the video frame sequence is sliced ​​and packetized, and a transmission protocol header and synchronization timestamp are added to each data packet to form a streaming media data packet and sent to the cloud service platform.

[0019] When receiving the digital control signal, the downlink data of the transmission channel is monitored in real time. When an inbound data packet is detected, the network protocol header is removed and data integrity is verified. After the verification is passed, the payload data containing displacement instructions, coin insertion trigger instructions or audio switching instructions is parsed out.

[0020] Preferably, the mechanical drive module parses the displacement command and drives the X-axis motor and Y-axis motor to control the coin acceptor to move to the target coordinate on the horizontal plane, specifically including the following steps:

[0021] The displacement command is analyzed to extract the target position coordinate data of the coin acceptor on the horizontal plane;

[0022] Obtain the current position coordinates of the coin acceptor, compare the current position coordinates with the target position coordinates, and determine the moving distance and moving direction in the X-axis and Y-axis directions respectively;

[0023] Based on the movement distance and direction along the X and Y axes, corresponding motor drive pulse signals or level control signals are generated respectively.

[0024] The motor drive pulse signal or level control signal is output to the motor drive circuit to coordinate the operation of the X-axis motor and the Y-axis motor until the coin acceptor reaches the target position coordinates.

[0025] Preferably, a method for controlling a remote coin acceptor includes the following steps:

[0026] S1. The main control terminal of the coin acceptor collects image information inside the machine casing, including the dynamic water flow and the current position of the coin acceptor. It encodes the image information into video data and uploads it to the cloud service platform, which then distributes it to the player's interactive terminal for real-time playback.

[0027] S2. The player interaction terminal receives and plays the video data, responds to the user's touch operation, generates a digital control signal containing displacement instructions, coin insertion action trigger instructions and audio switching instructions containing coin acceptor coordinate information, and sends the digital control signal to the cloud service platform.

[0030] S5. The coin-operated machine main control terminal parses the audio switching command and controls the audio output device to play preset background audio according to the command content, or receives and plays user-defined audio data from the player interaction terminal via Bluetooth protocol.

[0031] Preferably, in step S3, the cloud service platform receives the digital control signal from the player interaction terminal, identifies the target coin-operated machine main control terminal, and routes and forwards the digital control signal to the coin-operated machine main control terminal, specifically including the following steps:

[0032] The cloud service platform parses the received digital control signal and extracts the user identity identifier and session verification code contained therein;

[0035] The digital control signal is transmitted to the corresponding coin-operated machine main control terminal through the network long connection channel.

[0036] This invention provides a remote coin acceptor, its control system, and method. It offers the following advantages:

[0037] 1. This invention introduces water as a natural interference medium inside the liquid casing. The trajectory of the coin after it is released from the coin box into the water is completely affected by fluid dynamics, which has a high degree of physical randomness and unpredictability. This eliminates the possibility of human control of the result by electronic algorithms and enhances the realism and fairness of the device.

[0038] 2. The present invention uses a detachable connection structure consisting of connecting block one, connecting block three and threaded bolts, which allows the large liquid casing and base to be quickly separated into two independent modules. This not only reduces the volume and cost of packaging and transportation, but also allows for quick assembly after arrival at the site through simple operations. It also facilitates independent cleaning and maintenance of the liquid casing, improving the portability and site adaptability of the equipment.

[0039] 3. This invention achieves rapid lateral movement by driving a gear and rack with a first motor, and achieves precise longitudinal fine-tuning by driving a threaded rod with a second motor. This constructs a dual-axis drive logic that coordinates the X and Y axes. Combined with a network long connection and a video stream timestamp synchronization mechanism, it enables remote users to achieve high-precision omnidirectional positioning control of the coin box in a two-dimensional plane. Compared with unidirectional movement, this greatly enriches the game's strategy and operational freedom, while ensuring the immediacy of operation response. Attached Figure Description

A sliding rod 21 is slidably connected inside the connecting block 22. Both ends of the sliding rod 21 are fixedly connected to the outer wall of the rectangular slider 15. A coin box 23 is fixedly connected to the inner wall of the connecting block 22. A coin slot 24 is opened on the outer wall of the coin box 23. An electromagnetic actuator 25 is provided on the outer wall of the coin box 23. The control components include a control panel 9.

Control buttons 11 are provided inside the control panel 9. A joystick 12 is provided inside the control panel 9.

[0049] Specifically, a liquid housing 3 is attached to the upper surface of the base 1 to contain the water flow medium and the game scene. A connecting block 1 2 is fixedly connected to the outer wall of the base 1, and a connecting block 3 27 is fixedly connected to the corresponding position of the outer wall of the liquid housing 3. During assembly, the threaded bolt 26 is rotated so that its threaded end is screwed into the interior of the connecting block 3 27 and the connecting block 1 2 in sequence, thereby locking and fixing the liquid housing 3. It can be disassembled and separated by rotating in the opposite direction. The outer wall of the liquid housing 3 is also equipped with a water inlet 8 and a water outlet 7 for connecting to an external water circulation system to generate interference water flow or for cleaning and water replacement.

[0050] A camera 14 is fixedly connected to the outer wall of the liquid casing 3 via an L-shaped block 13. The camera 14 captures images directly facing the inside of the casing or through the glass window 4 set in the inner wall. A coin receiver 5 is set at the bottom of the inside of the casing, serving as the target landing point for the coin-operated game.

In order to prevent it from rotating and to play a guiding role, the sliding rod 21 passes through the connecting block 22, and both ends of the sliding rod 21 are fixedly connected to the outer wall of the rectangular slider 15.

[0053] Example 2:

[0054] Please see the appendix Figure 5 A control system for a remote coin acceptor includes a player interaction terminal, a cloud service platform, and a coin acceptor main control terminal connected sequentially via a communication network.

[0055] The player interaction terminal is equipped with a touch command generation module and a video display module. The video display module is used to receive and decode video stream data from the cloud service platform for real-time playback. The touch command generation module is used to respond to the user's touch operation, generate digital control signals containing displacement commands, coin insertion action trigger commands, and audio switching commands containing coin acceptor coordinate information, and send the digital control signals to the cloud service platform.

[0056] The cloud service platform is equipped with a signal routing and forwarding module and a streaming media distribution module. The signal routing and forwarding module is used to establish a long connection channel, receive digital control signals sent by the player's interactive terminal, and route and forward them to the corresponding coin-operated machine main control terminal. The streaming media distribution module is used to receive video data uploaded by the coin-operated machine main control terminal and distribute it to the player's interactive terminal.

[0057] The main control terminal of the coin acceptor is located inside the coin acceptor chassis and is equipped with a communication transmission module, a video acquisition module, a mechanical drive module and an audio control module;

[0058] The communication transmission module is used to maintain two-way communication with the cloud service platform, receive digital control signals and upload video data;

[0059] The video acquisition module is connected to a camera device installed inside the coin acceptor. It is used to acquire image information inside the machine, including the dynamic water flow and the position of the coin acceptor, and encodes the image information into video data for transmission to the communication module.

[0060] The mechanical drive module, connected to the motor drive circuit, is used to parse displacement commands and drive the X-axis motor and Y-axis motor to control the coin acceptor to move to the target coordinate on the horizontal plane; and to parse coin acceptance trigger commands and drive the transmission mechanism to perform the opening and closing actions of the coin slot.

[0061] The audio control module connects to the audio output device and is used to parse audio switching commands and control the audio output device to play preset background audio or user-defined audio transmitted via Bluetooth.

[0062] Furthermore, the communication transmission mode receiving digital control signals and uploading video data specifically includes the following steps:

[0063] Establish and maintain a long TCP connection or UDP transmission channel with the cloud service platform through the network protocol stack, and periodically send heartbeat data packets to keep the link active.

[0064] When uploading video data, the encoded video frame sequence output by the video acquisition module is obtained, the video frame sequence is sliced ​​and packetized, and a transmission protocol header and synchronization timestamp are added to each data packet to form a streaming media data packet and sent to the cloud service platform.

[0065] When receiving digital control signals, the system monitors the downlink data of the transmission channel in real time. When an inbound data packet is detected, the network protocol header is removed and data integrity is verified. After the verification is successful, the system parses out the payload data containing displacement instructions, coin insertion trigger instructions, or audio switching instructions.

[0066] Furthermore, the mechanical drive module parses the displacement command and drives the X-axis and Y-axis motors to control the coin acceptor to move to the target coordinates on the horizontal plane, specifically including the following steps:

[0067] Parse the displacement command and extract the target position coordinate data of the coin acceptor on the horizontal plane;

[0068] Obtain the current position coordinates of the coin acceptor, compare the current position coordinates with the target position coordinates, and determine the movement distance and direction in the X-axis and Y-axis directions respectively;

[0069] Based on the movement distance and direction along the X and Y axes, corresponding motor drive pulse signals or level control signals are generated respectively.

[0070] The motor drive pulse signal or level control signal is output to the motor drive circuit to coordinate the operation of the X-axis motor and the Y-axis motor until the coin acceptor reaches the target position coordinate.

[0071] Specifically, the system constructs a closed-loop control circuit consisting of a player interaction terminal, a cloud service platform, and a coin-operated machine main control terminal, all connected via a wide area network communication link. The player interaction terminal operates on a smart mobile device, and its video display module uses WebRTC or RTMP real-time streaming media protocols to establish a playback channel. It performs hardware decoding on the video stream data from the cloud and renders it onto the display screen. The touch command generation module listens for user touch events at the UI layer of the display screen. When it detects a dragging or clicking operation by the user within the screen area, it maps the touch point to dual-axis target coordinate values ​​in the internal coordinate system of the coin-operated machine. This coordinate data, along with the coin-operated action trigger command and audio switching command, is encapsulated into a custom binary or JSON format digital control signal, which is then sent to the cloud service platform via HTTPS or WebSocket protocols. The cloud service platform is equipped with a load balancer. Its signal routing and forwarding module maintains a mapping table and long connection handles between online player IDs and coin-operated machine IDs. When a digital control signal is received, it does not tamper with the business logic but directly transmits the signal to the target coin-operated machine's main control terminal through the established TCP or IP long connection channel based on the mapping relationship. The streaming media distribution module receives the video stream uploaded by the coin-operated machine, encapsulates it, and then pushes it to the player's terminal. The coin-operated machine's main control terminal, as the core execution unit, has its communication transmission module actively initiating a connection to the cloud by calling the network protocol stack interface when the system starts. It also starts a timed task to send heartbeat data packets every predetermined time, such as 5 seconds, to maintain link activity. In terms of video transmission, the video acquisition module acquires images inside the chassis, including water flow and the location of the coin-operated machine. These images are compressed into an H.264 bitstream by a hardware encoder, sliced ​​and packetized by the communication transmission module according to the RTP protocol, and uploaded after adding a sequence number and synchronization timestamp. Regarding command reception, the communication transmission module monitors the downlink port in real time, removes the network protocol header of the inbound data packet and performs CRC verification. After successful verification, the effective payload data is parsed out. The mechanical drive module is connected to the multi-axis stepper motor driver through the GPIO interface, responsible for achieving precise planar position control. After parsing the displacement command containing the target coordinates XT and YT, the mechanical drive module first reads the real-time position coordinates XC and YC of the coin acceptor on the horizontal slide rail. These coordinates are maintained by the system zeroing calibration and step accumulator. The module calculates the displacement deviation in the X-axis and Y-axis directions according to the following formulas:

[0072] ΔX=X T -X C ;

[0073] ΔY=Y T -Y C ;

[0074] Where ΔX and ΔY represent the distance to be moved along the X-axis and Y-axis, respectively, and their directions. T With Y TX represents the target location coordinates in the command. C With Y C Given the current real-time coordinates of the coin acceptor, after calculating the displacement deviation, in order to convert the distance into motor control signals, the mechanical drive module further uses the pulse conversion formula to calculate the number of pulses required to drive the X-axis motor and the Y-axis motor respectively:

[0075]

[0076] N x With N y These represent the total number of pulses required for the X-axis and Y-axis motors, respectively. α is the equivalent linear displacement of the lead screw corresponding to the motor step angle, i.e., the number of millimeters the lead screw moves by the slider with each motor rotation. P is the microstepping parameter of the motor driver. The module controls the direction pin level of the corresponding motor driver according to the positive and negative signs of ΔX and ΔY, using a hardware timer to... x With N y The module outputs a corresponding number of square wave pulses to the motor driver to drive the coin acceptor to move along the X and Y axes on the horizontal plane to the target position. When the coin acceptor action trigger command is parsed, the module controls the relay or servo circuit to close, driving the coin acceptor flip mechanism to move and then resetting after a delay. When the audio control module receives the audio switching command, it selects to call the preset background audio file stored locally according to the command content, or activates the Bluetooth A2DP protocol stack to receive and decode the custom audio stream from the player's interactive terminal, and drives the speaker to play it through the DAC circuit.

[0077] By clearly defining the coordinate comparison and pulse conversion logic for bidirectional coordinated movement along the X and Y axes, and combining the network long connection and video stream timestamp synchronization mechanism, high-precision positioning control and low-latency audio-visual interaction of the physical coin acceptor on a two-dimensional plane by remote users are achieved, ensuring the accuracy of the coin acceptor's omnidirectional movement in the horizontal dimension and the immediacy of the operation response.

[0078] Example 3:

[0079] This invention also provides a control method for a remote coin acceptor, comprising the following steps:

[0080] S1. The main control terminal of the coin acceptor collects image information inside the machine box, including the dynamic water flow and the current position of the coin acceptor. It encodes the image information into video data and uploads it to the cloud service platform, which then distributes it to the player's interactive terminal for real-time playback.

[0081] S2. The player interaction terminal receives and plays video data, responds to the user's touch operation, generates digital control signals containing displacement instructions, coin insertion action trigger instructions and audio switching instructions containing coin acceptor coordinate information, and sends the digital control signals to the cloud service platform.

[0082] S3, the cloud service platform receives digital control signals from the player's interactive terminal, identifies the target coin-operated machine main control terminal, and routes and forwards the digital control signals to the coin-operated machine main control terminal;

[0083] S4. The coin acceptor's main control terminal receives and analyzes digital control signals; according to the displacement command, it drives the X-axis motor and Y-axis motor to control the coin acceptor to move to the target coordinate on the horizontal plane; according to the coin accepting action trigger command, it drives the transmission mechanism to open the coin acceptor slot to release the game coin, and closes the coin acceptor slot after the action is completed.

[0084] S5, the coin-operated machine's main control terminal parses audio switching commands and controls the audio output device to play preset background audio according to the command content, or receives and plays user-defined audio data from the player's interactive terminal via Bluetooth protocol.

[0085] Furthermore, the cloud service platform receives digital control signals from the player's interactive terminal, identifies the target coin-operated machine's main control terminal, and routes and forwards the digital control signals to the coin-operated machine's main control terminal, specifically including the following steps:

[0086] The cloud service platform parses the received digital control signals and extracts the user identity identifier and session verification code contained therein;

[0087] Based on the user's identity identifier, retrieve the unique code of the coin-operated machine that has established a mapping relationship with it from the pre-set real-time online session list;

[0088] Based on the unique code of the coin-operated machine, locate the long-term network connection channel pre-established between the main control terminal of the coin-operated machine and the cloud service platform;

[0089] The digital control signals are transmitted to the corresponding coin-operated machine's main control terminal via a long-term network connection.

[0090] Specifically, the coin acceptor's main control terminal first initiates the initialization process. Through the communication transmission module, it calls the underlying network stack interface to initiate a connection request to the cloud service platform, establishes a stable TCP long connection or UDP transmission channel, and starts a timed task to send heartbeat data packets at a fixed frequency to ensure the link's penetration and activity in the NAT network environment. At the same time, the video acquisition module activates the high-definition camera device located inside the chassis to continuously collect image information including the dynamic water flow ripples inside the chassis and the real-time position of the coin acceptor on the slide rail. After being compressed by a hardware-accelerated H.264 or H.265 encoder, this image information is encapsulated by the communication transmission module into streaming media data packets with timestamp sequences according to the RTP / RTMP protocol and uploaded to the cloud service platform in real time.

[0091] As the central hub for data exchange, the cloud service platform receives video streams, performs protocol transcoding and encapsulation through the streaming media distribution module, and pushes the stream to the player interaction terminals with established sessions. The video display module of the player interaction terminal decodes and renders the downlink video data, restoring the real-time view of the coin acceptor on the screen. When the user drags or clicks in any direction on the touch area of ​​the screen, the touch command generation module captures the changes in the planar coordinates of the touch point, maps them to target parameters in the XY coordinate system of the coin acceptor, and combines the current coin acceptor action request and audio settings to generate digital control signals containing displacement commands, coin acceptor action trigger commands, and audio switching commands, which are then uploaded to the cloud service platform through an encrypted channel.

[0092] After receiving the signal, the signal routing and forwarding module of the cloud service platform does not parse the business logic. Instead, based on the device ID index in the signal packet header, it locates the channel handle of the target coin acceptor's main control terminal in the long-connection session pool and transmits the digital control signal in a directional manner. After the coin acceptor's main control terminal receives and verifies the signal, it enters the core instruction execution stage. For displacement instructions, the mechanical drive module parses the target position coordinates X of the coin acceptor on the horizontal plane. T With Y T The system simultaneously reads the current X and Y axis position coordinates of the coin acceptor, maintained by a grating ruler or stepper motor counter. C With Y C The module calculates the displacement deviation according to the following formulas:

[0093] ΔX=X T -X C ;

[0094] ΔY=Y T -Y C ;

[0095] Where ΔX and ΔY represent the distance and direction to be moved along the X and Y axes, respectively (positive values ​​represent forward movement, negative values ​​represent reverse movement), X T ,Y T Let X be the target coordinates. C ,Y C The current coordinates.

[0096] To drive the physical motors, the mechanical drive module further calculates the total number of pulses required to control the X-axis and Y-axis motors based on the pulse conversion formula:

[0097]

[0098] Where, N x With N yThese represent the number of pulses driving the X-axis and Y-axis motors, respectively. α is the equivalent linear displacement of the lead screw corresponding to the motor step angle, i.e., the number of millimeters the coin acceptor moves along the axis with each motor rotation. P is the microstepping setting parameter for the motor driver. The module sets the direction pin level of the corresponding motor driver according to the signs of ΔX and ΔY, and outputs N. x With N y A series of pulse signals work together to control the coin acceptor to move precisely to the target position along the horizontal slide rails of the X and Y axes.

[0099] Meanwhile, in response to the coin-insertion trigger command, the main control terminal drives the flip mechanism motor or electromagnet connected below the coin acceptor to open the coin slot and release the game coin. The game process is completed by utilizing the random interference characteristics of the water flow medium, and the device automatically resets after a delay. In response to the audio switching command, the main control terminal selects to call the locally stored background sound effect file or switches to Bluetooth slave mode according to the command flag. It receives and decodes the A2DP Bluetooth audio stream from the player's interactive terminal and plays user-defined music through the chassis speakers, realizing remote synchronization of audio-visual and operation.

[0100] By constructing control logic that includes coordinated X-axis and Y-axis drive, the coin acceptor achieves full freedom of movement on the horizontal plane. While ensuring that players can find the best landing point by moving the coin acceptor forward, backward, left, and right, the flexibility and strategy of operation are greatly improved. At the same time, by combining the physical interference of the water flow medium with low-latency remote video transmission, the convenience of remote control is retained, while the unpredictable hydrodynamic characteristics eliminate the possibility of electronic cheating, enhancing the realism and fairness of the game. In addition, the integration of Bluetooth custom audio function allows remote devices to play personalized background music according to the player's preferences, further enhancing the user's immersive entertainment experience.

[0101] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
