Description

Technical Field

[0001] This invention relates to self-service payment machines, and more specifically to a method for synchronous transmission control of receipts. Background Technology

[0002] Currently, the receipt printing mode of self-service payment equipment involves printing the receipt using a printing module or printer, and then sending it through the receipt transmission channel to the receipt dispensing port of the self-service payment equipment. There are two receipt transmission modes: one is to print and cut the receipt before sending it out, which is slower and requires no processing; the other is to send it out during the printing process, which is faster but requires corresponding processing.

[0003] However, since the printing module and the ticket transmission module are not integrated, there is a speed difference when transmitting between the two. This means that pulling or blocking may occur during the printing process, which may lead to distorted printed fonts or paper jams in the printer.

[0004] Therefore, it is necessary to design a new method to ensure that the printing module and the ticket transmission module maintain a consistent speed during transmission, thereby solving the problem of ticket pulling or blockage during the printing process. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for controlling the synchronous transmission of tickets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ticket synchronous transmission control method, applied in a self-service payment machine, the self-service payment machine including a printing module and a ticket transmission module, the printing module including a signal detection device, a controller, a cutter and a transmission assembly, the transmission assembly including a stepper motor and a transmission gear, the stepper motor being connected to the transmission gear; the signal detection device being connected to the controller; the stepper motor being connected to a driver, the signal detection device being used to detect the drive signal of the stepper motor to obtain the paper feed signal; the ticket transmission module including a ticket transmission assembly, the ticket transmission assembly including a driving wheel, a driven wheel and a power source, the power source being connected to the driving wheel, the driven wheel being connected to the driving wheel via a conveyor belt; the power source being connected to the controller;

[0007] The method includes:

[0008] The pulse count ratio between the power source and the stepper motor is determined by the signal detection device.

[0009] When a paper feed signal is detected, the paper feed signal is converted into a drive signal suitable for the stepper motor to synchronously transmit the ticket;

[0010] Once the cutter drive signal is detected, the detection of the paper feed signal stops after the cutter drive signal stabilizes, and the ticket transmission module is automatically driven until the ticket is completely transmitted out of the output slot.

[0011] After the ticket has been completely transmitted out of the ticket outlet, the detection of the paper feed signal is resumed, and the process of converting the paper feed signal into a drive signal suitable for the stepper motor is executed to synchronously transmit the ticket.

[0012] The further technical solution is as follows: the printing module further includes a cutter drive signal detection device, which is connected to the controller; the cutter drive signal detection device is used to detect the drive signal of the cutter.

[0013] The further technical solution is as follows: the printing module includes a first circuit board, the controller and the driver are respectively connected to the first circuit board, and the signal detection device is installed on the first circuit board.

[0014] The further technical solution is as follows: the stepper motor is provided with a coil, and the signal detection device is connected to the coil.

[0015] The further technical solution is as follows: the signal detection device is connected to the coil through coil mutual inductance.

[0016] A further technical solution is as follows: the signal detection device is connected to the controller through a voltage divider resistor; a shaping module is connected between the voltage divider resistor and the controller.

[0017] A further technical solution is as follows: determining the pulse count ratio between the power source and the stepper motor through the signal detection device includes:

[0018] The relationship between the paper feed length of the stepper motor and the number of drive pulse signals of the stepper motor driver is obtained to obtain a first correspondence.

[0019] The first correspondence is compared with the relationship between the paper length of the ticket transmission component and the number of drive pulses of the power source to obtain the pulse ratio between the power source and the stepper motor.

[0020] A further technical solution is as follows: when a paper feed signal is detected, the paper feed signal is converted into a drive signal suitable for the stepper motor to synchronously transmit the document, including:

[0021] When the signal detection device detects the paper feed signal, it converts the paper feed signal into a drive signal suitable for the stepper motor, and transmits the drive signal of the stepper motor to the power source so that the paper is transmitted synchronously.

[0022] The further technical solution is as follows: Upon detecting the cutter's drive signal, the system waits for the cutter's drive signal to stabilize before stopping the detection of the paper feed signal and automatically drives the document transmission module until the document is completely transmitted from the output slot, including:

[0023] When the cutter drive signal detection device detects the cutter drive signal, it waits for the cutter drive signal to stabilize and then stops working. It then automatically drives the power source of the ticket transmission module to work until the ticket is completely transmitted out of the ticket outlet.

[0024] The beneficial effects of this invention compared with the prior art are as follows: This invention determines the pulse ratio between the power source and the stepper motor through a signal detection device, realizes the conversion of the printing paper feed signal into a stepper motor drive signal to synchronously transmit the document, and stops detecting the printing paper feed signal when the cutter signal is stable, ensuring that the document is completely transmitted out of the document outlet before resuming detection and continuing synchronous transmission; this enables the printing module and the document transmission module to maintain a consistent speed during transmission, thereby solving the problem of document pulling or clogging during the printing process.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0037] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0038] Please see Figure 1 and Figure 4 , Figure 1 A schematic block diagram of a self-service payment machine provided in an embodiment of the present invention; Figure 4This is a flowchart illustrating the document synchronous transmission control method provided in an embodiment of the present invention. This method is primarily used in self-service payment machines. Since the printing module is a finished product, only one drive signal detection device 40 can be installed on the driver of the stepper motor 20 controlling the paper feed, to detect the drive signal of the paper feed stepper motor 20. A cutter drive signal detection device is installed on the cutter 10 module to detect the cutter 10 drive signal. A control signal detection device 40 is installed on the stepper motor 20 driver of the printer to detect the drive signal of the paper feed stepper motor 20 of the printing module in real time. Then, based on the detected signal, it is converted into a drive signal suitable for the document transmission channel motor. This requires considering the angular velocity ratio (drive pulse count ratio) between the two. First, the relationship between the paper feed length of the printer's paper feed stepper motor 20 and the number of drive pulse signals, as well as the corresponding relationship with the document transmission channel motor, is determined by measurement. This allows us to determine the ratio of drive pulse counts between the two motors. In actual operation, when a paper feed signal is detected, this signal can be converted according to a predetermined pulse count ratio to generate a drive signal suitable for the document transport motor, thus achieving speed synchronization between the two. When a paper cut signal is detected, the document transport channel will pause its detection of the paper feed signal and automatically drive the transport motor to completely deliver the document out of the output slot. After completing this process, the detection of the paper feed signal resumes, ensuring that the printing module or printer and the document transport channel maintain a consistent speed during transport, thereby resolving the problem of document pulling or clogging during printing.

[0039] Please see Figures 1 to 4 The aforementioned method for synchronous transmission control of receipts is characterized in that it is applied to a self-service payment machine. The self-service payment machine includes a printing module and a receipt transmission module. The printing module includes a signal detection device 40, a controller, a cutter 10, and a transmission assembly. The transmission assembly includes a stepper motor 20 and a transmission gear, with the stepper motor 20 connected to the transmission gear. The signal detection device 40 is connected to the controller. The stepper motor 20 is connected to a driver, and the signal detection device 40 is used to detect the drive signal of the stepper motor 20 to obtain a paper feed signal. The receipt transmission module includes a receipt transmission assembly, which includes a driving wheel 60, a driven wheel 80, and a power source 50. The power source 50 is connected to the driving wheel 60, and the driven wheel 80 is connected to the driving wheel 60 via a conveyor belt. The power source 50 is connected to the controller.

[0040] The drive signal detection device 40 is connected to the driver of the stepper motor 20. The stepper motor 20 provides power to the ticket transmission part, and its rotation speed is controlled by the printing paper feed speed detected by the drive signal detection device 40. The ticket transmission assembly consists of a drive wheel 60, a driven wheel 80, and a pressure adjusting spring 90. The drive wheel 60 and the driven wheel 80 clamp the ticket, and the clamping force is controlled by the pressure adjusting spring 90. Driven by the power source 50, the printed ticket is synchronously conveyed to the ticket outlet.

[0041] In this embodiment, the power source 50 mentioned above is actually a stepper motor 20, which is also connected to a driver.

[0042] In one embodiment, the printing module further includes a cutter drive signal detection device, which is connected to the controller; the cutter drive signal detection device is used to detect the drive signal of the cutter 10.

[0043] In one embodiment, please refer to Figure 1 The aforementioned printing module includes a first circuit board 30, a controller and a driver respectively connected to the first circuit board 30, and a signal detection device 40 mounted on the first circuit board 30.

[0044] In this embodiment, the signal detection device 40 is directly connected to the circuit board of the printing module, that is, as shown below. Figure 2 The access point 1 shown is simple and its principle is clear.

[0045] In one embodiment, please refer to Figure 1 The stepper motor 20 is equipped with a coil, and the signal detection device 40 is connected to the coil.

[0046] In one embodiment, please refer to Figure 2 The aforementioned signal detection device 40 is connected to the coil via coil inductance.

[0047] In one embodiment, please refer to Figure 3 The aforementioned signal detection device 40 is connected to the controller via a voltage divider resistor; a shaping module is connected between the voltage divider resistor and the controller.

[0048] In one embodiment, please refer to Figure 1 The driven wheel 80 is provided with a pressure adjusting spring 90 for adjusting the distance between the driven wheel 80 and the driving wheel 60.

[0049] Furthermore, when the signal detection device 40 is connected to both ends of the coil of the stepper motor 20, that is... Figure 2 and Figure 3 The access point 2 can be connected by coil mutual inductance or resistor voltage division, but it needs to be shaped before it can drive the power source 50 of the ticket transmission component.

[0050] Since the stepper motor 20 and the document transmission module have different power sources 50 and different transmission structures, their angular velocities are likely to differ when transmitting documents. Considering that different manufacturers may have multiple printing modules, it is necessary to be able to set the angular velocity ratio between the stepper motor 20 and the power source 50 of the document transmission module, which can be converted into a ratio of the number of drive pulses.

[0051] The coordinated operation of stepper motor 20 and signal detection device 40 achieves high-precision paper feed control, ensuring accurate printing. The document transmission module works synchronously with the printing module, preventing document accumulation or delayed transmission and improving system efficiency. Signal detection device 40 provides real-time drive signal detection and feedback, enabling the controller to adjust the operating status of each component promptly, ensuring normal system operation. Signal processing via voltage divider resistors and a shaping module reduces interference during signal transmission, improving system stability and reliability. The clear division of labor and well-defined structure of each module facilitates testing and maintenance, reducing system failure rate and maintenance costs. The modular system design allows for easy functional expansion or hardware upgrades based on actual needs, providing excellent scalability.

[0052] In one embodiment, please refer to Figure 4 The above method includes steps S110 to S140.

[0053] S110. The pulse ratio between the power source 50 and the stepper motor 20 is determined by the signal detection device 40.

[0054] In this embodiment, the main purpose of this step is to determine the pulse count ratio between the power source 50 driving the ticket transmission and the stepper motor 20 using the signal detection device 40. This ratio is crucial because it determines the synchronization and accuracy of the ticket transmission system.

[0055] In one embodiment, please refer to Figure 5 The above step S110 may include steps S111 to S112.

[0056] S111. Obtain the relationship between the paper feed length of the stepper motor 20 and the number of drive pulse signals of the driver of the stepper motor 20 to obtain a first correspondence.

[0057] In this embodiment, the distance the printed ticket advances when the stepper motor 20 sends a certain number of drive pulses is obtained through actual experiments or data analysis. This relationship is derived based on the characteristics and mechanical structure of the stepper motor 20 and can be called the first correspondence relationship.

[0058] Specifically, the relationship between the paper feed length of the stepper motor 20 and the number of drive pulse signals of the driver of the stepper motor 20 is obtained by measurement or other means.

[0059] S112. Compare the first correspondence with the relationship between the paper length of the ticket transmission component and the number of drive pulses of the power source 50 to obtain the pulse ratio between the power source 50 and the stepper motor 20.

[0060] In this embodiment, the obtained first correspondence is compared with the paper length of the document transmission assembly and the number of drive pulses of the power source 50 to calculate the pulse ratio between the power source 50 and the stepper motor 20. This ensures coordinated and synchronous operation of printing paper feed and document transmission.

[0061] This ensures that the stepper motor 20 and the power source 50 operate in the correct ratio, thereby guaranteeing accuracy during document transmission. It avoids document transmission problems caused by pulse mismatch, such as paper jams and misalignment.

[0062] S120. When a paper feed signal is detected, the paper feed signal is converted into a drive signal suitable for the stepper motor 20 to synchronously transmit the document.

[0063] Specifically, when the signal detection device 40 detects a paper feed signal, it converts the paper feed signal into a drive signal suitable for the stepper motor 20, and transmits the drive signal of the stepper motor 20 to the power source 50 so that the paper is transmitted synchronously.

[0064] In this embodiment, after detecting the paper feed signal, the signal detection device 40 converts the signal into a drive signal suitable for the stepper motor 20, ensuring that the stepper motor 20 can work according to the set step size and speed, thereby realizing the synchronous transmission of the document.

[0065] This ensures timely response to paper feed signals from the printer, avoiding delays. Maintaining synchronization between the stepper motor 20 and the printer reduces potential problems during document transfer.

[0066] S130. After detecting the drive signal of the cutter 10, wait for the drive signal of the cutter 10 to stabilize and then stop detecting the paper feed signal. Automatically drive the ticket transmission module until the ticket is completely transmitted out of the ticket outlet.

[0067] Specifically, when the cutter drive signal detection device detects the drive signal of the cutter 10, it waits for the drive signal of the cutter 10 to stabilize and then stops the operation of the signal detection device 40, and automatically drives the power source 50 of the ticket transmission module to work until the ticket is completely transmitted out of the ticket outlet.

[0068] Specifically, when the cutter 10 drive signal is detected, the system will pause the detection of the paper feed signal and then automatically drive the power source 50 of the ticket transmission module to continue transmitting the ticket until it is completely out of the output slot.

[0069] Stop detecting other signals during the operation of cutter 10 to avoid operational conflicts; ensure that the ticket is transmitted completely out of the ticket outlet to improve user experience.

[0070] S140. After the ticket has been completely transmitted out of the ticket outlet, resume the detection of the paper feed signal and execute step S120.

[0071] Once the ticket has been completely transmitted from the output slot, the system resumes detecting the paper feed signal and re-enters step S120 to prepare for the next printing task.

[0072] The system can process multiple printing tasks continuously, improving work efficiency. After each transmission is completed, the system automatically adjusts and prepares for the next detection and transmission.

[0073] Overall, this method ensures efficient, synchronized, and accurate operation between the printer and the document transmission system, greatly improving the reliability of printing and document transmission and the user experience.

[0074] The aforementioned document synchronous transmission control method determines the pulse ratio between the power source 50 and the stepper motor 20 through the signal detection device 40, thereby converting the printing paper feed signal into a stepper motor 20 drive signal for synchronous document transmission. When the cutter 10 signal stabilizes, the detection of the printing paper feed signal is stopped, and the detection is resumed and synchronous transmission continues after the document is completely transmitted out of the document outlet. This ensures that the printing module and the document transmission module maintain a consistent speed during transmission, thus solving the problem of document pulling or blockage during printing.
