Description

Technical Field

[0001] The present invention relates to the technical field of device program burning, and more specifically, to an automatic program burning system, method, device, and storage medium. Background Art

[0002] In a digital inkjet printer system, each FPGA and CPU needs to undergo program burning processing. Existing program burning devices usually rely on a computer and a manufacturer's burner, and the burning is carried out by manually operating the burning software. This burning method has many problems. First of all, generally, burners are one-to-one burned, and the burning efficiency is extremely low. In large-scale production or equipment maintenance, a large amount of time and labor costs are required. Secondly, manual operation is prone to misoperation, such as selecting the wrong program file, connection error, etc., which may lead to burning the wrong program and affect the normal operation of the device. In addition, the traditional burning method lacks an effective post-burning verification mechanism, making it difficult to ensure that the burned program is completely correct, increasing the difficulty of device debugging and fault troubleshooting.

[0003] Therefore, the existing technology burning devices have low efficiency and are prone to errors, and cannot meet the need for simultaneous burning of multiple chips. Summary of the Invention

[0004] In order to overcome the problems of low efficiency and easy error of the existing technology burning devices and the inability to meet the need for simultaneous burning of multiple chips, the present invention designs an automatic program burning system, method, device, and storage medium, which can effectively solve the above technical problems.

[0016] The CPU main control chip is connected to the Flash program storage chip through the SPI bus for synchronously transmitting the program stored in the Flash program storage chip to multiple target CPUs.

[0017] The indicator unit includes:

[0018] A blue indicator light for indicating successful burning;

[0019] A yellow indicator light for indicating that burning is in progress;

[0020] A red indicator light for indicating burning failure.

[0021] The burning channel includes two reset buttons.

[0022] A method for automatic program burning includes the following steps:

[0023] Pre-burn the FPGA program and the CPU program to be burned into the Flash program storage chip;

[0028] If the programming fails, press the reset button again to perform secondary programming.

[0029] After the program is programmed, the CPU performs secondary verification on the program version. After the verification passes, the programming success information is displayed on the display unit.

[0051] The model of the Flash program storage chip is W25Q64JVZEIQ.

[0052] The CPU main control chip is connected to the Flash program storage chip through the SPI bus, and is used to synchronously transfer the programs stored in the Flash program storage chip to multiple target CPUs.

[0053] The indicator unit includes:

[0055] A yellow indicator light for indicating that the burning is in progress;

[0056] A red indicator light for indicating burning failure.

[0057] The burning channel contains two reset buttons.

[0058] In a digital inkjet printer production factory, to improve production efficiency, the program automatic burning system of the present invention is introduced. The main control unit of the system selects the FPGA main control chip of model LFXP2-17E6QN208C and the CPU main control chip of model LPC1778FBD144. The Flash program storage chip of the storage unit adopts W25Q64JVZEIQ, and its storage capacity is 64 Mbit, which can meet the storage requirements of a large number of burning programs. The burning interface unit is provided with 4 independent burning channels, and each channel is equipped with an independent CPU burning port and an FPGA burning port, and can be connected to 4 printer control boards to be burned simultaneously.

[0059] The display unit uses a liquid crystal display screen, which is connected to the CPU main control chip of the main control unit through the SPI interface. It can clearly display the version number of the burning program, such as "V1.2.3". When an error occurs during the burning process, the screen will display an error message, such as "Program checksum error". After the burning is completed, the burning result and the number of burning times will be displayed. If the burning is successful, it will display "Burning successful, this is the 5th burning". The indicator unit is installed at a prominent position on the system shell. The blue, yellow and red indicator lights are respectively used to indicate the successful, in-progress and failed states of burning. The reset button of the verification unit is designed as a mechanical button with clear tactile feedback and is connected to the GPIO pin of the CPU main control chip.

[0060] In actual use, technicians first burn the FPGA program and CPU program adapted to the digital inkjet printer into the Flash program storage chip through a professional programmer. When the printer control board on the production line is transferred to the burning station, the operator connects the CPU burning port and FPGA burning port of the board to the corresponding interfaces of the burning interface unit respectively, presses the reset button, and the burning process starts automatically. The yellow indicator light comes on, and the display unit updates the burning progress information in real time. If the burning process is successful, the blue indicator light comes on, and the display unit shows that the burning is successful; if a fault occurs, the red indicator light comes on, and the display unit reports an error. After the operator troubleshoots the problem according to the error message, presses the reset button again for secondary burning. After the burning is completed, the CPU performs a secondary verification on the program version to ensure that the burning is accurate and error-free. The whole process is efficient and stable, greatly improving the production efficiency.

[0061] Embodiment 2

[0062] A method for automatic program burning, please refer to Figures 1-3 , including the following steps:

[0063] Pre-burn the FPGA program and CPU program to be burned into the Flash program storage chip;

[0064] After the system is powered on, the CPU main control chip synchronously transfers the program in the Flash storage chip to multiple target CPUs through the SPI bus;

[0065] Multiple target CPUs respectively synchronously store the program information to be burned into their respective corresponding Flash chips;

[0066] Connect the CPU burning port and FPGA burning port of the target board to be burned to the corresponding burning ports of the system respectively, press the reset button, and enter the automatic burning state;

[0067] During the burning process, the yellow indicator light comes on, indicating that the burning is in progress; the blue indicator light comes on, indicating that the burning is successful; the red indicator light comes on, indicating that the burning fails;

[0068] If the burning fails, press the reset button again for secondary burning;

[0069] After the program burning is completed, the CPU performs a secondary verification on the program version. After the verification passes, the display unit shows the successful burning information.

[0070] A device includes a processor, a memory, and a computer program stored on the memory and executable on the processor. When the computer program is executed by the processor, it performs the steps of the above-mentioned program automatic burning method.

[0071] A storage medium has a computer program stored thereon. When the computer program is executed by a processor, the steps of the above-mentioned program automatic burning method are implemented.

[0072] In a specific implementation, when applying the program automatic burning method of the present invention to burn programs for a batch of industrial controllers, first, a technician uses a professional burning tool to burn the FPGA program and CPU program adapted to the industrial controller into a Flash program storage chip of model W25Q64JVZEIQ.

[0073] Power on the burning system. The CPU main control chip (model LPC1778FBD144) establishes communication with the Flash program storage chip through the SPI bus. Under the synchronization of the clock signal, the CPU main control chip sequentially reads out the program data stored in the Flash chip byte by byte and synchronously transmits it to multiple target CPUs. These target CPUs respectively correspond to different industrial controller boards. After each target CPU receives the program data, it synchronously stores it into the corresponding Flash chip on its own board.

[0074] The operator accurately connects the CPU burning port and FPGA burning port of the industrial controller board to be burned to the corresponding burning ports of the burning system according to the interface identification, and then presses the reset button on the burning channel. The burning system enters the automatic burning state. During the burning process, the yellow indicator light in the indicator unit inside the burning system lights up, indicating that the burning is in progress. The burning system accurately writes the program data into the FPGA and CPU storage areas of the industrial controller through the SPI bus and other communication protocols.

[0075] If an abnormality occurs during the burning process, such as communication interruption, data verification error, etc., the burning system will immediately stop burning, and the red indicator light will light up. After the operator checks the connection line and confirms the integrity of the program data, presses the reset button again, and the system starts burning again. When the burning is successfully completed, the blue indicator light lights up. Finally, the CPU performs a secondary verification on the program version burned into the industrial controller, compares the key feature information of the program with the pre-stored standard verification value. If the verification passes, the display unit of the burning system displays "Burning successful, program version verification passed", and the operator can perform the next assembly and test on the burned industrial controller, ensuring the accuracy and stability of the industrial controller program burning.
