Description

Technical Field

[0002] Currently, in the communication scenario between the host computer and the slave computer in embedded design, the host computer and the slave computer usually need to transfer files, and the slave computer needs to send debugging information to the host computer through the serial port for software debugging and development.

[0003] In the prior art, the host computer and the slave computer share a single serial port for file transfer and debugging information transfer. When the host computer and the slave computer use the serial port to transfer files, since the serial port is already occupied at this time, it is impossible to output debugging information simultaneously. As a result, the data transmission process is a black box for developers of the embedded serial port transmission protocol, and it is impossible to track the data transmission process in real time. Once a transmission anomaly or error occurs during the file transfer process, it is very difficult to locate the problem with the transmission anomaly. Summary of the Invention

[0031] In order to make the objectives, technical solutions and advantages of this application clearer, the following will further describe this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0032] It should be noted that the technical solutions between the embodiments of the present application can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] Referring to Figure 1 As shown, it is a schematic diagram of a data transmission system based on dual serial ports of the present application. The system includes a host computer and a slave computer. Specifically, the host computer includes a first serial port module of the host computer and a second serial port module of the host computer, and the slave computer includes a first serial port module of the slave computer and a second serial port module of the slave computer;

[0034] The first serial port module of the host computer is communicatively connected to the first serial port module of the slave computer through a first serial bus, and the first serial bus is used to transmit first data to be transmitted from the host computer to the slave computer for the slave computer to obtain second data to be transmitted;

[0035] The second serial port module of the host computer is communicatively connected to the second serial port module of the slave computer through a second serial bus. The second serial bus is used to send the debugging information pre-generated by the slave computer to the host computer, and at the same time, the second data to be transmitted is transmitted back to the host computer in real time for the host computer to verify whether the first data to be transmitted is the same as the second data to be transmitted.

[0036] In an actual communication scenario between the host computer and the slave computer, since the host computer and the slave computer usually need to transfer files, and the slave computer needs to send debugging information to the host computer through the serial port module for software debugging and development. In the existing technical solutions, file transfer and debugging information transfer share a serial port module. When the host computer and the slave computer use the serial port module to transfer files, at this time, since the serial port module is already occupied, it is impossible to output debugging information anymore, resulting in the file transfer process being equivalent to a black box. Once a transmission anomaly occurs during the file transfer process, it is very difficult to locate the problem.

[0037] In this embodiment, the first serial bus and the second serial bus can be a universal serial data bus (for example, UART) for asynchronous communication, and the two-way communication of this bus can achieve full-duplex transmission and reception. The first serial port module of the host computer and the first serial port module of the slave computer communicatively connected through the first serial bus are used to transfer files. It should be noted that when the first serial port module of the host computer and the first serial port module of the slave computer transfer files, they need to follow the corresponding transfer protocol. For example, the commonly used protocols include xmodem, ymodem, zmodem protocols, etc. When using the serial port module to transfer files, corresponding driver software is required to control the serial port module to conform to the protocol standard.

[0038] The upper computer second serial port module and the lower computer second serial port module connected by the second serial bus communication are used to transmit debugging information, and are also used to copy the file transmitted from the upper computer to the lower computer and re-transmit it back to the upper computer, so that the upper computer can verify whether the file sent to the lower computer is the same as the file returned by the lower computer, so as to judge whether the transmitted file is inconsistent. Since the file transmitted from the upper computer to the lower computer will be transmitted back to the upper computer in real time, the upper computer can monitor the file data stream received by the lower computer in real time. For example, if it is detected that there is a loss of data bytes in the file data stream received by the lower computer, it may be that the CPU of the lower computer is too late to obtain the data in the FIFO memory of the lower computer first serial port module, resulting in FIFO memory overflow. At this time, this problem can be solved by reducing the baud rate and slowing down the transmission speed.

[0039] By adding a new serial port, the lower computer can use the new serial port to transmit the file sent by the upper computer back to the upper computer, and at the same time send the debugging information to the upper computer. The debugging personnel can monitor the file data stream transmitted between the upper computer first serial port module and the lower computer first serial port module in real time through the upper computer, as well as the current debugging information of the lower computer. When the file transmission is abnormal, more abnormal information can be obtained for problem analysis and location, so as to monitor the file transmission process, and the upper computer can also receive the debugging information of the lower computer synchronously during the debugging process.

[0040] Refer to Figure 2 As shown, this application provides a method flow diagram of an embodiment of a data transmission method based on dual serial ports. This method can be executed by the upper computer of the data transmission system based on dual serial ports. The upper computer can be an electronic device such as a computer, and the upper computer can be implemented by software and / or hardware. The data transmission method based on dual serial ports includes:

[0041] Step S110: Transmit the first data to be transmitted stored in the upper computer file buffer to the upper computer first serial port module;

[0042] Step S120: Use the first serial bus to send the first data to be transmitted of the upper computer first serial port module to the lower computer first serial port module, so that the lower computer second serial port module can obtain the second data to be transmitted;

[0043] Step S130: Receive the second data to be transmitted and the debugging information pre-generated by the lower computer that are simultaneously sent by the lower computer second serial port module to the upper computer second serial port module through the second serial bus.

[0044] In this embodiment, when the host computer sends data to be transmitted (e.g., a file) to the slave computer, the data to be transmitted stored in the file buffer of the host computer (e.g., the Buffer buffer) is copied and transmitted to the FIFO memory in the first serial port module of the host computer. The FIFO memory is a buffer link in the system and is a first-in, first-out dual-port buffer, that is, the first data entering the FIFO memory will be the first to be removed.

[0045] The file in the first serial port module of the host computer is sent to the FIFO memory in the first serial port module of the slave computer by using the first serial bus. The slave computer can copy the file received in its FIFO memory to the file buffer of the slave computer (e.g., the Buffer buffer). The slave computer sends the file in its file buffer to the second serial port module of the slave computer, and the second serial port module of the slave computer can send the file to the second serial port module of the host computer. Since the second serial port module of the host computer and the second serial port module of the slave computer are not used as file transfer serial ports but as debug serial ports, this serial port can not comply with the requirements of the file transfer protocol. Therefore, the second serial port module of the slave computer can send debug information to the second serial port module of the host computer at the same time.

[0046] The data to be transmitted and the debug information pre-generated by the slave computer that are simultaneously sent by the second serial port module of the slave computer to the second serial port module of the host computer are received in real time. Since the slave computer transmits the file sent by the host computer back to the host computer in real time through the second serial port module of the slave computer, the host computer can compare and verify the sent file with the file sent back by the slave computer, so as to monitor in real time whether there is a transmission error in the file received by the slave computer. It can be understood that the first data to be transmitted refers to the file data sent by the host computer to the slave computer, and the second data to be transmitted refers to the file data that the slave computer transmits back to the host computer through the second serial bus after receiving the file data sent by the host computer.

[0047] Compared with the single-serial-port data transmission scheme in the prior art, in this application, by adding a new serial port, the file data stream transmitted between the first serial port module of the host computer and the first serial port module of the slave computer, as well as the current debug information of the slave computer, can be monitored in real time. When a transmission anomaly occurs in the file data, more anomaly information is obtained for problem analysis and location, so as to monitor the file transmission process, avoid the black-box debugging situation of a single serial port in the prior art, and the host computer can also receive the debug information of the slave computer synchronously during the debugging process.

[0048] In one embodiment, before transmitting the first data to be transmitted stored in the file buffer of the host computer to the first serial port module of the host computer, the method further includes:

[0049] Transfer the first data to be transmitted from the external storage space to the file buffer of the host computer.

[0050] The host computer CPU can pre-copy the file to be transmitted to the lower computer from the corresponding external storage space of the host computer to the file buffer of the host computer, which can effectively reduce the waiting time when the host computer transmits the file to the lower computer.

[0051] In one embodiment, after transferring the first data to be transmitted stored in the file buffer of the host computer to the first serial port module of the host computer, the method further includes:

[0052] Use the data acquisition module pre-configured in the FIFO memory of the first serial port module of the host computer to acquire the first data to be transmitted sent by the first serial port module of the host computer.

[0053] By configuring the data acquisition module in the FIFO memory of the first serial port module of the host computer, the file sent out from the FIFO memory of the first serial port module of the host computer can be acquired in real time.

[0054] Further, the method further includes:

[0055] Verify whether the second data to be transmitted sent by the second serial port module of the lower computer is the same as the first data to be transmitted acquired by the data acquisition module.

[0056] When the host computer receives the file returned by the second serial port module of the lower computer, it can check whether the returned file is consistent with the file sent by the host computer acquired by the acquisition module, that is, the host computer can verify whether the file sent out is the same as the file returned by the lower computer. If they are not the same, it means that the transmission is abnormal. At this time, an alarm message can be generated to remind the relevant debugging personnel.

[0057] In one embodiment, the method further includes:

[0058] Display the second data to be transmitted and the debugging information simultaneously sent by the second serial port module of the lower computer on the preset interface of the host computer. By displaying the file and debugging information simultaneously sent by the second serial port module of the lower computer on the screen of the host computer, the debugging personnel can timely know the debugging information and the file transmission situation.

[0059] Refer to Figure 3 As shown, it is a flowchart schematic diagram of another preferred embodiment of the data transmission method based on dual serial ports of the present application. This method can be executed by the lower computer of the data transmission system based on dual serial ports. The lower computer can be an industrial control electronic device, and the lower computer can be implemented by software and / or hardware. The data transmission method based on dual serial ports includes:

[0060] Step S210: Receive the first data to be transmitted sent by the first serial port module of the host computer to the first serial port module of the slave computer via the first serial bus;

[0061] Step S220: Transmit the first data to be transmitted received by the first serial port module of the slave computer to the second serial port module of the slave computer to obtain the second data to be transmitted;

[0062] Step S230: Transmit the second data to be transmitted of the second serial port module of the slave computer and the pre-generated debugging information to the second serial port module of the host computer via the second serial bus.

[0063] In this embodiment, the first serial port module of the host computer uses the first serial bus to send data to be transmitted (e.g., a file) to the FIFO memory of the first serial port module of the slave computer. After the slave computer receives the file, it sends the file received by the first serial port module of the slave computer to the second serial port module of the slave computer, and then uses the second serial bus to send the file of the second serial port module of the slave computer and the pre-generated debugging information to the second serial port module of the host computer. Since the second serial port module of the host computer and the second serial port module of the slave computer are not used as a file transfer serial port but as a debugging serial port, this serial port can not comply with the requirements of the file transfer protocol. Therefore, the second serial port module of the slave computer can send debugging information to the second serial port module of the host computer at the same time.

[0064] Since the slave computer transmits the file sent by the host computer back to the host computer in real time through the second serial port module of the slave computer, the host computer can compare and verify the file sent out with the file transmitted back by the slave computer, so as to monitor in real time whether there is a transmission error in the file received by the slave computer.

[0065] Compared with the single-serial-port data transmission scheme in the prior art, the present application can, by adding a new serial port, monitor in real time the file data stream transmitted between the first serial port module of the host computer and the first serial port module of the slave computer, as well as the current debugging information of the slave computer. When there is an abnormal situation in the file data transmission, more abnormal information can be obtained for problem analysis and location, so as to monitor the file transmission process, avoid the black-box debugging of a single serial port in the prior art, and the host computer can also receive the debugging information of the slave computer synchronously during the debugging process.

[0066] Further, the transmitting the first data to be transmitted received by the first serial port module of the slave computer to the second serial port module of the slave computer includes:

[0067] Transmit the first data to be transmitted received by the first serial port module of the slave computer to the file buffer of the slave computer;

[0068] Send the first data to be transmitted in the lower computer file buffer to the second serial port module of the lower computer.

[0069] Transmit the file received by the first serial port module of the lower computer to the lower computer file buffer, and send the file in the lower computer file buffer to the second serial port module of the lower computer, which can effectively reduce the waiting time when the first serial port module of the lower computer transmits the file to the second serial port module of the lower computer.
