Description

Technical Field

[0001] This utility model relates to a control, specifically, to a control board for a dedicated ticket printing device. Background Technology

[0002] The subway automatic ticket vending machine system is controlled by a microcomputer, with powerful functions, flexible settings, and high stability; it has equipment such as two-dimensional barcode printing / activation, proximity card recognition, ticket printing, bank card recognition, and PIN pad; the existing ticket printing device consists of a paper loading mechanism, a printing control board, and a mounting bracket.

[0003] In recent years, with the continuous improvement of microprocessor performance and the reduction of cost, microprocessor-based printer control boards have gradually become mainstream. This type of system features powerful functionality, flexible settings, and high stability. A dedicated ticket printer processes the data to be printed on the ARM processor and then sends the processed data to the FPGA. This involves the issue of serial and parallel data transmission between the ARM and FPGA. Data transmission from the ARM to the FPGA must consider the speed of data processing by the thermal printhead, while also leveraging the advantages of the FPGA to maximize the amount of data transmitted and match the data requirements of the thermal printhead. Existing printer control boards use a 245 bus for transmission. While this method can fully realize data interaction, the resources used between the ARM and FPGA, including SRAM and the 245 driver chip, increase economic costs and make the design more complex.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0016] Example

[0017] like Figure 1 , 2 As shown, this utility model discloses a control board for a dedicated ticket printing device, including a central control processor, a serial-to-parallel data conversion interface connected to the central control processor, a printhead motion control unit connected to the serial-to-parallel data conversion interface, and a printhead heating control unit connected to the serial-to-parallel data conversion interface. In this embodiment, the central control processor is model CY7C68013A.

[0018] In this embodiment, the serial-to-parallel data conversion interface includes a configuration register, a synchronous core, an asynchronous core, an address path module, a data path module, an IPS interface, and an output control module connected to the configuration register, as well as an AXI interface and a clock gating module connected to both the synchronous and asynchronous cores. The configuration register is used to configure the processor's operating mode, including synchronous or asynchronous operation delay signals, data interface width, data address multiplexing, and address space. The synchronous core is a key hardware component for time synchronization, using a built-in high-precision clock source and time synchronization algorithm to accurately transmit time synchronization signals to various devices in the system. The asynchronous core is a commonly used hardware component for transferring data between different clock domains, helping to handle data conversion and synchronization issues. The address path module stores the address path; the data path module stores the data path; and the IPS interface is the connection interface for data transmission between the screen and the processor. The AXI interface, short for Advanced eXtensible Interface, is a high-performance, low-cost, scalable high-speed bus interface introduced by ARM. It is part of ARM's AMBA (Advanced Microcontroller Bus Architecture); the AXI interface is designed for applications requiring high performance, high bandwidth, and low latency. The clock gating module reduces unnecessary clock switching activity in the circuit by controlling the transmission of the clock signal, thereby reducing dynamic power consumption. The output control module controls the transmission of data between the central control processor and the printhead motion control unit and printhead heating control unit.

[0019] In this embodiment, the printhead motion control unit includes a first STM8 control board, a limit sensor and a stepper motor controller connected to the first STM8 control board, and a stepper motor connected to the stepper motor controller. In this embodiment, the printhead heating control unit includes a second STM8 control board, a temperature sensor and a MOSFET switching module connected to the second STM8 control board, and a heating module connected to the MOSFET switching module. The first and second STM8 control boards share a single control board. The STM8 control board effectively reduces the computational and data transmission load on the central control processor, thus improving the overall efficiency of the printhead control board to some extent.

[0020] All modules and sensors in this invention can be obtained directly through procurement. Those skilled in the art can select the appropriate modules based on the module functions described in the specification. Their specific structures and models will not be elaborated further.

[0021] Through the above design, this utility model, based on a central control processor and an STM8 dedicated ticket printing device control board, optimizes data transmission through a high-efficiency serial-parallel data transmission interface, effectively reducing economic costs while simplifying design complexity. This design results in faster and more flexible data transmission, better matching the processing speed of the thermal printhead, maximizing the advantages of the STM8, and achieving more efficient printing control.

[0022] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model.
