[0002] In the prior art, the upgrade of the optical sensing communication terminal is achieved by updating and expanding the functions of the optical sensing communication terminal by burning new firmware or software programs. In actual applications, since the application scenarios and installation scenarios of the optical sensing communication terminal are all in special environments such as underground, pipe corridors, and underwater, the optical sensing communication terminal cannot be directly connected to the terminal for hardware during debugging and upgrading after installation. In addition, due to the special installation environment of the optical sensing communication terminal, the terminal itself has high requirements for waterproof performance, so a large number of serial ports cannot be set.

[0040] With respect to the existing upgrade method of optical sensing communication terminals, when the present application detects that an external device transmits a data packet through a communication serial port, the present application stops transmitting log data to the external device and switches to a receiving mode, receives and parses the data packet, obtains a verification file and an upgrade file of the data packet, and determines whether the data packet meets a preset order condition based on the verification file. If so, the data packet is confirmed to be an upgrade package and a response is made, and the optical sensing communication terminal is upgraded based on the upgrade file. This scheme pre-sets the data packet format of the upgrade package to confirm whether the received data packet is an upgrade package, thereby realizing the determination of the upgrade package, and realizing the reception of the upgrade package and the terminal upgrade through a communication serial port that sends logs in the current optical sensing communication terminal, and realizing the reception of the upgrade package through the serial port that sends logs in the current optical sensing communication terminal, thereby reducing the upgrade cost of the optical sensing communication terminal and improving the upgrade efficiency of the optical sensing communication terminal.

[0041] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0042] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 A schematic diagram of a first embodiment of a method for upgrading an optical sensing communication terminal provided by an embodiment of the present invention, the method specifically comprises the following steps:

[0043] 101. Transmit log data to external devices through the communication serial port.

[0044] The log data includes at least one of the sleep data, operation data, and execution data of disturbing the optical cable of the optical sensing communication terminal. The sleep data records the time, reason, and related status information of the optical sensing communication terminal entering the sleep state during the sleep period. For example, if the terminal automatically enters the sleep state when no data transmission is required, the log can record the timestamp of the start of sleep, the operation status before sleep, the power consumption during sleep, and other information; the operation data covers various parameters and performance indicators of the optical sensing communication terminal under normal working conditions, including but not limited to data transmission rate, signal strength, bit error rate, operating voltage, temperature, etc. For example, if the data transmission rate of the terminal suddenly drops, the problem can be located by analyzing the relevant parameters in the operation data, and corresponding measures can be taken to repair it; the execution data of disturbing the optical cable is that when the optical cable is subjected to external disturbances (such as vibration, bending, stretching, etc.), the optical sensing communication terminal may perform specific operations to deal with these disturbances. The execution data of the disturbed optical cable records the detailed information of these operations, including the type, time, location of the disturbance, and the countermeasures taken by the terminal. For example, if the optical cable is frequently disturbed by vibration at a certain location, the terminal may execute a specific algorithm to reduce the impact of vibration on signal transmission. By analyzing the execution data, the effectiveness of these algorithms can be evaluated and optimized. The optical sensor communication terminal continuously sends disordered log content through the serial port. When the optical sensor communication terminal needs to be upgraded, the host computer sends an upgrade package to the optical sensor communication terminal through the serial port or other communication methods. The optical sensor communication terminal receives the upgrade package and upgrades it.

[0045] The optical sensing communication terminal is used to clamp on the optical cable and disturb the optical cable. The optical sensing communication terminal is only provided with one communication serial port, and the communication serial port is used to connect to an external device and transmit data with the external device. The communication serial port can be extended to the ground or water surface by an extension line, so as to facilitate the external device to connect to the communication serial port. The communication serial port sends and receives bytes according to bits. The extension line is a cable or connector, which is used to extend the communication serial port on the device to another position so as to connect it at a position far away from the original interface. In the optical sensing communication terminal, the communication serial port can be conveniently extended from the device itself to the ground or near the water surface by using an extension line, so as to facilitate the user to connect other devices or cables. For extension to the ground or the water surface, that is, the communication serial port is not limited to the physical position of the optical sensing communication terminal itself, but can be extended to a position that is easier to access or more suitable for connection by using an extension line. The main purpose of the communication serial port is to allow external devices to communicate with the optical sensing communication terminal. After the communication serial port is extended to the ground or the water surface by using an extension line, external devices can be connected at these positions to realize data input or output.

[0046] 102. When it is detected that an external device transmits a data packet to the optical sensor communication terminal through the communication serial port, stop sending log data and control the communication serial port to switch to a receiving mode.

[0047] The optical sensing communication terminal monitors the data packets transmitted through the communication serial port through the built-in sensor or other detection mechanism. After detecting the data packet, the optical sensing communication terminal triggers a signal to notify the serial port controller. The function of the signal is to instruct the serial port controller to switch from the current mode (which may be idle, sending or other modes) to the receiving mode. After receiving the instruction to switch the mode, the serial port controller will perform the corresponding operation and set the communication serial port to the receiving mode. Specifically, the mode of the communication serial port is switched to the receiving mode by adjusting the configuration parameters of the communication serial port, such as baud rate, data bit, stop bit and check bit. In the receiving mode, the communication serial port will start to receive data packets from the sender, and the received data will be converted into digital form and stored in the receiving buffer for subsequent processing. It can be understood that the external device sends an orderly upgrade package to the optical sensing communication terminal through the communication serial port. Before the external device sends the data packet, it needs to establish a connection with the external device through the communication serial port, and after the connection is established, it receives the data packet sent by the external device, and based on the judgment of the orderliness of the data packet, it realizes the judgment of whether the data packet is an upgrade package, and after confirming that it is an upgrade package, the optical sensing communication terminal is upgraded based on the upgrade package.

[0048] 103. Receive a data packet through the communication serial port, parse the data packet, and obtain a verification file and an upgrade file of the data packet.

[0049] When receiving a data packet through the communication serial port and parsing the data packet to obtain the verification file and the upgrade file, the optical sensing communication terminal monitors whether there is a data packet transmission through the communication serial port, triggers the receiving mechanism when the data packet is detected, and the communication serial port switches to the receiving mode to receive the data according to the set parameters such as baud rate, data bit, stop bit and check bit. For the received data packet, the data packet is parsed by the parsing tool to check whether the received data contains a specific frame header, such as AA, BB. The frame header is used to identify the beginning of a frame of data, and the data length field is parsed. The data length field indicates the size of the load data in the current data frame. Further, the received data can also be checked according to the CRC check code in the data packet. Whether the received data is correct. After confirming that the data is complete and correct, the data of the verification file and the upgrade file are extracted from the data packet according to the data length field. For the upgrade file, according to the format and content of the upgrade file, the corresponding upgrade operation is performed, such as updating the firmware, modifying the configuration, etc.

[0050] 104. Determine whether the data packet meets the preset order condition based on the verification file.

[0051] In this embodiment, the format of the upgrade package is pre-defined in the optical sensing communication terminal, and the format may be: upgrade package header + upgrade file + upgrade package tail. Furthermore, relevant information about the upgrade content may be added to the upgrade package. Specifically, the upgrade package is designed into a specific file format, in which the first few lines and the last few lines are orderly file contents, so that the optical sensing communication terminal can recognize and trigger the upgrade process. For example, the upgrade package may have a specific start mark as the content of the first few lines, and an end mark as the content of the last few lines. After parsing the received data packet, the optical sensing communication terminal searches for the specific start mark and end mark. When the start mark and the end mark are identified, it is confirmed that the data packet meets the preset order condition. The verification file is a byte segment used to verify the orderliness of the data packet, including at least a header field and a tail field.

[0052] When the terminal is upgraded based on the upgrade package, the orderliness of the upgrade package is judged for the data packet, and when the preset order condition is not met, the error handling mechanism is triggered. The error handling mechanism includes confirming the transmission information and data packet information of the data packet, and reporting the data packet and suspending the receiving and processing of the data packet based on the corresponding security mechanism. Specifically, if the preset order condition is not met, the error handling mechanism is triggered, including recording error logs, sending alarms, etc., and further security measures may be taken, such as isolating or disabling the file transfer of the source. Alternatively, the information of verification failure and the judgment result of the preset order condition are fed back to the user, and the received data packet that does not belong to the upgrade package is further parsed, the type and content of the data packet are confirmed, and the relevant information is sent to the user, and the user receives the processing result of the data packet that does not belong to the upgrade package. It should be noted that for the received data packet that is not an upgrade package, it should be ensured that it will not cause any damage to the optical sensing communication terminal, for example, setting an isolation file for the received data packet of the non-upgrade package, restricting its access rights or automatically deleting it.

[0053] 105. If the conditions are met, confirm that the data packet is an upgrade packet, respond to the data packet confirmed as the upgrade packet, and upgrade the optical sensor communication terminal based on the upgrade file.

[0054] After receiving the complete upgrade package, the optical sensor communication terminal stops sending disordered logs through the communication serial port and performs corresponding upgrade operations according to the upgrade file. The upgrade process includes software update, configuration modification, etc. After the upgrade is completed, the optical sensor communication terminal resets or reinitializes and resumes sending disordered logs through the serial port. Before stopping the log sending, you can consider backing up the logs being sent to the storage medium.

[0055] In this embodiment, ordinary data packets (such as logs) will not have headers and tails added, only upgrade packages will have headers and tails added. The optical sensor communication terminal continuously sends logs through the serial port, and the log content is in a disordered state. By setting the upgrade package to a file with the first few lines and the last few lines in order, when the optical sensor communication terminal receives the upgrade package, it stops sending logs and performs an upgrade, and continues sending logs after the upgrade is completed.

[0056] In one implementable method, the header of the upgrade package is 0xAA, and the trailer of the upgrade package is 0x55. Furthermore, in addition to the header and trailer, the upgrade package may further include: 1 byte representing the checksum of the entire package, 2 bytes representing the total data length of the upgrade package, 1 byte representing the total number of upgrade packages, 1 byte representing the package number of the current upgrade package, and finally the data field of the entire upgrade package will be encrypted. After receiving a data packet, the optical sensor communication terminal will determine whether the header of the data packet is AA and the tail is 55. If so, it means that the data packet is an upgrade packet, and the next step is to continue analysis. If the further analysis is correct, the optical sensor communication terminal will organize a response packet. The header of the response packet is AA, the tail is 55, and then there is a byte A5 in the data field, indicating that this packet is an upgrade packet responding to the host computer. There is 1 byte in the upgrade packet to indicate the total number of upgrade packets, and 1 byte to indicate the packet sequence number of the current upgrade packet. If the packet sequence number of the data packet received by the optical sensor communication terminal is equal to the total number of packets, it means that the optical sensor communication terminal has received all the upgrade packets sent by the host computer, and the packet sequence number of each upgrade packet sent by the host computer will increase by 1. Specifically, the host computer splits the file to be sent, for example, a file of 30K in size, into 30 data packets, each of which is 1K. 0xAA is added to the header of each data packet and 0x55 is added to the end of the data packet. The host computer then sends the data packet to the optical sensor communication terminal through the communication serial port. The optical sensor communication terminal recognizes that the header of the data packet is 0xAA and the end is 0x55, and considers that the data packet is an upgraded data packet rather than log information.

[0057] It should be noted that the optical sensing communication terminal is upgraded only after receiving all the upgrade packages sent by the host computer; there is 1 byte in the upgrade package to indicate the total number of upgrade packages, and 1 byte to indicate the package number of the current upgrade package. If the package number received by the terminal is equal to the total number of packages, it means that the terminal has received all the upgrade packages sent by the host computer. Specifically, the external device prepares the upgrade package, which is a series of data packets containing update data. Each upgrade package has a unique package number and a byte indicating the total number of upgrade packages. The external device sends the upgrade packages to the optical sensing communication terminal one by one in sequence. The optical sensing communication terminal receives the upgrade packages from the external device. For each received upgrade package, the terminal reads the package number and the total number of packages. The terminal verifies whether the received package number is within the expected range (i.e., not greater than the total number of packages), and checks whether there is any packet loss or disorder. When the terminal receives an upgrade package with a package number equal to the total number of packages, it confirms that all upgrade packages have been received. If the terminal detects any packet loss or disorder, it will request the external device to resend the lost package or the entire upgrade package sequence. After confirming that all upgrade packages have been received and verifying the integrity and order of the packages, the terminal will begin the upgrade process, which includes writing the new software into the memory of the optical sensing communication terminal, restarting the terminal to apply the new software, and performing any post-upgrade configuration or verification steps.

[0058] This solution pre-sets the data packet format of the upgrade package to confirm whether the received data packet is an upgrade package, thereby realizing the determination of the upgrade package and realizing the reception of the upgrade package through the serial port that sends the log in the current optical sensor communication terminal.

[0059] See also Figure 2 , a schematic diagram of a second embodiment of a method for upgrading an optical sensing communication terminal provided by an embodiment of the present invention, the method specifically comprises the following steps:

[0060] 201. Establish a communication connection between the optical sensing communication terminal and an external device.

[0061] The external device is the sender of the upgrade package, and the external device has at least one communication interface, and the communication interface is used to connect to a communication serial port on the optical sensing communication terminal and send the upgrade package to the communication serial port. In practical applications, the external device is an emulator, and the communication interface is a SWD (Serial Wire Debug) interface. The communication serial port on the optical sensing communication terminal can send and receive data to the external device, that is, an I / O interface. When the communication serial port sends data to the external device, the T1 OUT interface sends data to the external device, and there is a T1 IN interface connected to the T1 OUT interface inside the optical sensing communication terminal. When the communication serial port receives data from the external device, the R1 IN interface sends data to the external device, and there is an R1 OUT interface connected to the R1 IN interface inside the optical sensing communication terminal. The emulator is connected to and communicates with the optical sensing communication terminal through the SWD interface.

[0062] 202. Initialize the communication serial port of the optical sensor communication terminal, and detect whether there is a data packet transmission on the communication serial port.

[0063] Initializing the communication serial port includes setting the baud rate, data bit, stop bit, check bit, flow control setting, buffer setting, interrupt setting, data transmission mode selection, etc. After the initialization is completed, set the same serial port parameters as the optical sensor communication terminal, and monitor the communication serial port to wait for the data packet sent by the external device.

[0064] 203. When the optical sensor communication terminal detects that a data packet is transmitted through the communication serial port, the optical sensor communication terminal is controlled to stop sending data, and the communication serial port is controlled to switch to a receiving mode.

[0065] At the hardware level, the communication of the communication serial port is bidirectional, but it is necessary to control when to send and when to receive. When the optical sensor communication terminal needs to send a log, it will configure the serial port to send mode and send the log data. When the optical sensor communication terminal detects that there is data incoming, it will switch to receive mode and read the incoming data. When the optical sensor communication terminal receives data while sending a log, it switches to receive mode through the interrupt service program and uses a buffer to store the data to be sent or received. When the optical sensor communication terminal is sending a log, it can store the received upgrade package data in the buffer until the current log is sent. Use a state machine to manage the sending and receiving status of the serial port, define different states, such as "sending logs", "receiving data packets", etc., and switch states according to the current state and received data. Specifically, the optical sensing communication terminal will monitor the signal on the communication serial port. When it detects that a data packet is transmitted through the serial port line, the optical sensing communication terminal will recognize the signal. Once the data packet is recognized, the optical sensing communication terminal will send an instruction to the serial port controller, requiring it to switch to the receiving mode. The serial port controller will then parse the transmitted data packet according to the configured parameters and convert it into digital form and store it in the receiving buffer.

[0066] 204. Receive a data packet through the communication serial port, and perform integrity check based on the data load of the data packet. When the check result shows that the data packet is complete, parse and split the data packet based on the parsing method to obtain a verification file and an upgrade file of the data packet.

[0067] When the optical sensing communication terminal receives a complete upgrade package, it should stop sending logs and start processing the upgrade package. The upgrade process may include steps such as verifying the integrity of the upgrade package, executing the upgrade operation, and restarting the device. The data packet mainly includes: a packet header, which contains the control information of the data packet, such as the destination address, source address, checksum, etc., which is used to indicate the sender and receiver of the data packet, as well as the type and length of the data packet. The upgrade file is the actual data part carried by the data packet. The packet tail contains additional checksum information, which is used to detect whether the data is erroneous or lost during transmission. For the received data packet, first verify the integrity of the data packet. If the data packet contains checksum information, calculate the checksum value of the received data, compare the calculated checksum value with the checksum value in the data packet, and verify the integrity of the data packet. For the data packet that passes the checksum, parse out the various parts according to the format definition of the data packet, identify the location of the verification file and the upgrade file in the data packet, extract the data of the verification file and the upgrade file from the data packet, and save them to the appropriate file or memory area.

[0068] The specific steps of data packet parsing include: first, check the version field of the data packet header, confirm the protocol of the data packet, confirm the source address and destination address of the data packet, parse the payload of the data packet, and the specific parsing method depends on the protocol type and content of the payload, then check the checksum field in the data packet header, verify the integrity of the data packet, and select the appropriate parsing method according to the format and content of the data packet. For text data, you can use the text parsing package, and for binary data, you can use the binary parsing package, etc.

[0069] 205. Match the header field and the tail field in the verification file with the preset correspondence table between the data packet type and the header and tail format to determine whether the data packet meets the preset order condition.

[0070] Match the header field with the header format in the correspondence table between the preset data packet type and the header and footer format, determine whether the header field exists in the header format, and obtain a first judgment result; match the footer field with the footer format in the correspondence table between the preset data packet type and the header and footer format, determine whether the footer field exists in the footer format, and obtain a second judgment result; integrate the first judgment result and the second judgment result to obtain a matching result. In actual applications, a correspondence table between the preset data packet type and the header and footer format is defined, and the correspondence table includes various data packet types and their corresponding header and footer formats. For example, the correspondence table includes the following fields: data packet type (ID), header format (Header Format), and footer format (Footer Format).

[0071] When a data packet is received, it is parsed into a header field, a data part, and a tail field. The upgrade file is the data part, and the verification file is the header field and the tail field. Extract the header field in the data packet, find the header format corresponding to the current data packet type in the preset correspondence table, match the extracted header field with the preset header format, and judge whether the header field exists in the preset header format to obtain a first judgment result; extract the tail field in the data packet, find the tail format corresponding to the current data packet type in the preset correspondence table, match the extracted tail field with the preset tail format, and judge whether the tail field exists in the preset tail format to obtain a second judgment result; according to the first judgment result and the second judgment result, determine whether the data packet completely matches the preset header and tail formats. If the first judgment result and the second judgment result are both present, that is, the header and the tail match, then the data packet matches successfully, confirming that the data packet meets the preset order condition. If any judgment result is not present, then the data packet fails to match.

[0072] 206. After the upgrade package is received, a response package corresponding to the upgrade package is obtained, and a response is made to the upgrade package based on the response package.

[0073] The structure of the upgrade package is pre-set, including a byte indicating the total number of upgrade packages and a byte indicating the sequence number of the current upgrade package. During the receiving process, the optical sensing communication terminal should continuously track the received package sequence number and compare it with the total number of upgrade packages. In addition to the comparison of the package sequence number and the total number of packages, additional integrity verification mechanisms such as checksum or cyclic redundancy check can also be implemented. The checksum is calculated by summing the data and comparing it with the sender. Furthermore, a suitable timeout period can be set. If the expected upgrade package is not received within a certain period of time, the terminal can request the external device to retransmit the package.

[0074] After the upgrade package is received, the corresponding response package will be obtained from the preset storage area. The response package is generated according to the reception result of the upgrade package by the optical sensing communication terminal. For example, the response package may include the reception result of the upgrade package being successfully received, missing, or wrong. After the data packet meets the preset order condition, it is confirmed as an upgrade package, and the package sequence number and the total number of packages are extracted from the upgrade package. The information is usually located in the header or a specific field of the upgrade package. The package sequence number of the currently received upgrade package is compared with the package sequence number of the received upgrade package. If the current package sequence number is continuously increasing and has reached the total number of packages, it means that the upgrade package has been sent. After confirming that the upgrade package has been sent, the corresponding response package is extracted from a predefined position or based on the protocol rules. The response package contains confirmation information, receiving status or other relevant information for the upgrade package, and the response package is sent to the sender of the upgrade package through the communication serial port. It should be noted that the response package can be preset or generated in real time according to the reception result of the upgrade package by the optical sensing communication terminal.

[0075] This solution pre-sets the data packet format of the upgrade package to confirm whether the received data packet is an upgrade package, thereby realizing the determination of the upgrade package and realizing the reception of the upgrade package through the serial port that sends the log in the current optical sensor communication terminal.
