[0026] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0027] like Figures 1 to 5 As shown, it is a schematic diagram of the structure of the automatic firmware adaptation burning system and method provided by the present invention. The automatic firmware adaptation burning system includes an input device 10, a communication card 20 connected to the input device 10, a plurality of test boards 30 connected to the communication card 20, and a plurality of infrared scanners 40 connected to the test boards 30. It can be imagined that the automatic firmware adaptation burning system and method also include other functional modules, such as a control module, a storage module, and a transmission module, etc., which are well known to those skilled in the art and will not be repeated here.

[0028] The input device 10 is used to input and store the programming parameters of different modules, which can be called when needed. The input device 10 can be an input device such as a USB flash drive, a programmable input panel, or a host computer to input and store the programming parameters of different models of modules.

[0029] The communication card 20 serves as an information transfer terminal between the input device 10 and the test board 30 and is used to call data and realize multi-communication.

[0030] The communication card 20 includes a microcontroller 21 , a USB interface 22 , and a communication card communication module 23 .

[0031] The microcontroller 21 is used to receive the module model output from the test board 30, and according to the received module model, call the burning parameters corresponding to the model from the input device 10 and transmit them to the test board 30. One end of the communication card 20 is connected to the input device 10 through the USB interface 22, and the other end is connected to multiple test boards 20 respectively through the communication card communication module 23, so as to realize one-to-many communication. The communication card communication module 23 can use the modbus / CAN bus communication mode, or can use Bluetooth, WiFi, or 2.4g and other wireless communication modes.

[0032] The test board 30 includes a microprocessor 31, a test board communication module 32 connected to the communication card communication module 23, an analog power supply module 33 for power supply, a hardware self-test module 34, and a display driver module 35 connected to the hardware self-test module 34.

[0033] The microprocessor 31 is a single chip microcomputer and is used to control the test board 30. A single chip microcomputer is an integrated circuit chip that uses ultra-large-scale integrated circuit technology to integrate modules with multiple functions into one chip. It is well known that a single chip microcomputer should have a central processing unit CPU, a read-only memory ROM, an interrupt system, a timer / counter, an analog multiplexer, and an A / D converter and other functional modules to control the operation of the entire test board 30. It should be a prior art and will not be described in detail here.

[0034] The test board communication module 32 can use bus communication or wireless communication, but it should match the communication mode of the communication card communication module 23. The test board 30 is provided with a plurality of detection points connected to the hardware self-checking module 34. The detection points detect the voltage of different hardware. The hardware self-checking module 34 determines whether the voltage is within the normal range and displays the detection result on the display driver module 35, so that it can intuitively know which specific hardware is damaged, which is convenient for subsequent maintenance.

[0035] One of the test boards 30 is connected to one of the infrared scanners 40 and corresponds to one module. The infrared scanner 40 is used to read the model information of the module, specifically by scanning the QR code on the module to determine the model. Then the model information is sent to the communication card 20 through the test board communication module 32. The communication card 20 obtains the product burning parameters of the corresponding model from the database of the input device 10 according to the model, and then forwards them to the test board 30 through the communication card communication module 23, and the test board 30 performs burning.

[0036] In order to be compatible with any module, the test board 30 is divided into an application layer 310, a function module layer 320, a process event layer 330, a protocol layer 340, and a hardware driver layer 350 from top to bottom in terms of program hierarchical management. The higher the level, the higher the level.

[0037] The application layer 310 is used to expand the use of the test board. Burning is only one of the applications. Other applications can be added to the application layer 310 to achieve other functions. The application layer 310 schedules the functional module layer 320.

[0038] The functional module layer 320 divides the control flow of a burning application into several functional modules, and the functional module layer 320 schedules the process event layer 330. The functional module divisions corresponding to the burning of different models of products are the same, and the difference is the process events. In the process event layer 320, the process events governed by each functional module are classified according to the product model, which is convenient for the functional module to schedule the corresponding process events. The process event layer 330 schedules the protocol layer 340 and the hardware driver layer 350. Therefore, after the communication board 20 forwards the burning parameters of the corresponding model of the product to the test board 30, the test board 30 selects the corresponding process event according to the model for burning, realizing automatic adaptation and compatibility with any module.

[0039] The protocol layer 340 is a communication protocol and a special algorithm, such as modbus / CAN wireless communication, USB driver protocol, and CRC check algorithm, etc. The protocol layer 340 schedules the hardware driver layer 350 .

[0040] The hardware driver layer 350 is used to drive the hardware of the test board 30, such as driving the RAM / ROM space management driver to store and cache the burning data during burning, and driving the A / D converter of the microprocessor 31 to convert the analog signal into a digital signal and transmit it to the hardware self-test module 34, that is, converting an input voltage signal into an output digital signal, so that the hardware self-test module 34 can detect whether each hardware is normal.

[0041] The present invention provides a method for automatically adapting firmware, comprising the following steps:

[0042] S1: Provide an input device 10, a communication card 20 connected to the input device 10, a plurality of test boards 30 connected to the communication card 20, and a plurality of infrared scanners 40 connected to the test board 30. The test board 30 includes a microprocessor 31. One test board 30 is connected to one infrared scanner 40 and corresponds to one module. The test board 30 controls the infrared scanner 40 to read the model information of the module and sends the model information to the communication card 20.

[0043] S2: the communication card 20 obtains the burning information data corresponding to the model from the input device 10 and forwards it to the test board 30 .

[0044] S3: The test board 30 automatically matches the corresponding firmware for burning according to the model information.

[0045] S4: Before burning, the microprocessor 31 needs to set aside a buffer RAM1 to store the data to be burned, divide the burned data into N parts, and burn 1 / N data into the ROM space of the module IC each time. While burning, the CRC check value V1 of the RAM1 buffer data is calculated.

[0046] S5: After the 1 / N data is burned, the microprocessor 31 opens a buffer RAM2, then reads the 1 / N data just burned in the ROM of the module IC and stores it in RAM2, and then waits for the next cycle of burning data to calculate the CRC check value V2 for the data in the buffer RAM2, and repeats this cycle until the N copies of the burning data are burned and the CRC check value V2 of the N copies of the burning data is obtained. In this way, the burning is not affected, and the calculation of V1 and V2 is completed by using the burning time.

[0047] S6: Compare the CRC check value V1 with the accumulated CRC check value V2 of the N pieces of programming data to determine whether the programming is successful.

[0048] Compared with the prior art, the automatic firmware adaptation burning system provided by the present invention divides the test board 30 into an application layer 310, a function module layer 320, a process event layer 330, a protocol layer 340, and a hardware driver layer 350 according to hierarchical management in the program. The function module layer 320 divides a burning control process into several function modules. The function module division corresponding to the burning of products of different models is the same, and the difference is the process event. In the process event layer 320, the process events governed by each function module are classified according to the product model, which is convenient for the function module to schedule the corresponding process event. When burning, the test board 30 can select the corresponding process event according to the model for burning, so as to realize automatic adaptation and compatibility with any module. In addition, the burning method of the automatic firmware adaptation stores the data to be burned in the buffer RAM1 and divides the burning data into N parts before burning, burns 1 / N data into the ROM space of the module IC each time, calculates the CRC check value V1 of the RAM1 buffer data while burning, and after the burning of 1 / N data is completed, the microprocessor 31 opens up a buffer RAM2, then reads out the 1 / N data just burned in the ROM of the module IC and stores it in the RAM2, waits for the next cycle of burning data, calculates the CRC check value V2 for the data in the buffer RAM2, and so on circulates until the burning of N parts of burning data is completed, and obtains the CRC check value V2 of the N parts of burning data. This does not affect the burning, and the burning time is used to complete the calculation of V1 and V2, thereby improving the efficiency and speed of verification and realizing the burning self-check.
