Description
Technical Field
[0001] The present application relates to the technical field of ultrasonic heat meters, and in particular to a method and device for processing an ultrasonic heat meter application. Background Art
[0002] As ultrasonic heat meters are often deployed in harsh environments such as high temperature, strong magnetic field and strong electric field, their RS485 communication lines are susceptible to external interference such as high pulses. In addition, the heat meter itself may have insufficient anti-electromagnetic interference capabilities, which may cause errors in the application stored in the FLASH memory and even data loss. Such problems may cause abnormal operation of specific functional modules, or even cause the entire system to crash, freeze and restart ineffectively, and other serious consequences.
[0003] At present, the traditional response to such failures is to dismantle the shell of the ultrasonic heat meter and use a professional firmware burning tool to rewrite the firmware into the heat meter's memory. However, in actual operation, since ultrasonic heat meters are usually installed at high altitudes or in narrow pipe wells, this undoubtedly greatly increases the difficulty and danger of on-site disassembly and operation. In addition, manual intervention during the disassembly process often destroys the original sealing and protection measures inside the heat meter, which will reduce the protection level of the heat meter and may also have an adverse effect on its performance parameters, thereby seriously affecting the subsequent stable operation of the heat meter.
[0004] Therefore, there is an urgent need for a processing method and device for an ultrasonic heat meter application that can solve the above technical problems. Summary of the invention
[0005] The present application provides a method and device for processing an ultrasonic heat meter application. The method effectively solves the problem that the ultrasonic heat meter is difficult to disassemble and maintain due to the special installation location during actual operation through non-disassembly automated steps. At the same time, it also avoids the potential damage to the internal protection measures and performance parameters of the heat meter by manual disassembly, thereby ensuring the subsequent normal operation of the heat meter.
[0006] In the first aspect, the present application provides a method for processing an ultrasonic heat meter application, which is applied to a server, and the method includes: obtaining a first identifier and a first verification value of a program to be detected, where the program to be detected is an application in an ultrasonic heat meter; determining whether the first identifier exists in a preset identifier table, where the preset identifier table is a table composed of identifiers corresponding to preset backup data; when the first identifier exists in the preset identifier table, determining whether the first verification value is consistent with the preset verification value, where the preset verification value is a verification value corresponding to the first identifier; if it is determined that the first verification value is inconsistent with the preset verification value, obtaining first data corresponding to the preset verification value from the preset backup data; replacing the second data according to the first data, where the second data is data corresponding to the program to be detected.
[0007] By adopting the above technical solution, the first identification and the first check value of the program to be detected are obtained, and compared with the preset identification table and the preset check value, so that the internal application program can be detected and verified without disassembling the heat meter, which greatly reduces the difficulty of operation and realizes rapid verification through comparison. The automated detection process, once the first check value is found to be inconsistent with the preset check value, the correct first data is immediately obtained from the preset backup data, and the first data is replaced with the second data, which improves the efficiency of detection and repair, reduces manual intervention, and helps to ensure the stable operation of the heat meter after detection.
[0008] Optionally, before determining whether the first identifier exists in the preset identifier table, the method also includes: receiving a backup request sent by the host computer, determining the starting address, byte length and second check value according to the backup request; determining the third data according to the starting address and byte length, and obtaining a third check value corresponding to the third data; determining whether the second check value is consistent with the third check value; when the second check value is consistent with the third check value, obtaining the operating status of the external storage chip; if it is determined that the operating status is normal, obtaining the second identifier corresponding to the third data; writing the third data, the second identifier and the second check value into the external storage chip, the external storage chip including a first corresponding relationship and a second corresponding relationship, the first corresponding relationship being the corresponding relationship between the third data and the second identifier, the second corresponding relationship being the corresponding relationship between the second check value and the third data, and writing the third data into the preset backup data.
[0009] By adopting the above technical solution, a backup request sent by a host computer is received, and the starting address, byte length and second check value are parsed, thereby ensuring that the source of the data backup is clear and verifiable. After obtaining the third data to be backed up, the third check value corresponding to the third data is calculated, and compared with the second check value provided by the host computer, which can effectively verify the integrity and accuracy of the data. After determining that the second check value is consistent with the third check value, the operating status of the external storage chip is obtained to ensure that the external storage chip is in a normal state before performing a data write operation, thereby avoiding data loss or write failure caused by a storage chip failure; adding a second representation to the third data makes the third data more traceable, and writing the third data, the second identifier and the second check value into the external storage chip to facilitate subsequent query of backup data.
[0010] Optionally, after writing the third data, the second identifier and the second verification value into the external storage chip, the method also includes: obtaining the target backup data from the external storage chip, calculating the target backup data to obtain a fourth verification value; determining whether the fourth verification value is consistent with the second verification value; when the fourth verification value is consistent with the second verification value, confirming that a prompt indicating the third data backup is successful is sent to the host computer.
[0011] By adopting the above technical solution, the target backup data is obtained from the external storage chip, and its fourth check value is calculated, which can be compared with the second check value provided by the host computer during the backup, ensuring that the data recovered from the storage chip is consistent with the original backup data in content and has not been damaged or tampered with; when the fourth check value is consistent with the second check value, the backup data is confirmed to be successful, and a prompt is sent to the host computer; this confirmation mechanism increases the accuracy of the backup data when the backup data is subsequently retrieved, reduces the need for manual intervention, and improves the accuracy of data management.
[0012] Optionally, after determining whether the second verification value is consistent with the third verification value, the method further includes: when the second verification value is inconsistent with the third verification value, confirming to send a backup failure prompt to the upper computer.
[0013] By adopting the above technical solution, during the data backup process, if the second verification value does not match the third verification value, it can be immediately identified and a prompt of backup failure can be sent to the host computer. This instant feedback mechanism helps users quickly realize the existence of the problem and take corresponding solutions.
[0014] Optionally, before obtaining the first identifier and the first verification value of the program to be detected, the method also includes: determining whether the first verification value of the program to be detected can be obtained; if it is determined that the first verification value of the program to be detected cannot be obtained, using a watchdog to timeout reset the server and run the boot program.
[0015] By adopting the above technical solution, when the first check value of the program to be tested cannot be obtained, it may mean that the program is in a dead state. At this time, the server is reset through the watchdog mechanism to quickly restore to normal operation, avoid continuous operation in an unsafe state, and reduce the risk of downtime and data loss due to failures.
[0016] Optionally, after determining that the first verification value is inconsistent with the preset verification value, the method also includes: using a reset program to reset and start the server, and running the boot program, and again obtaining the fifth verification value from the external storage chip; again obtaining the sixth verification value of the program to be tested; determining whether the fifth verification value is consistent with the sixth verification value; when the fifth verification value is inconsistent with the sixth verification value, confirming that the fourth data corresponding to the fifth verification value is obtained from the preset backup data, and outputting the fourth data as the first data.
[0017] By adopting the above technical solution, after the server is reset and started, by obtaining the fifth verification value from the external storage chip again and comparing it with the sixth verification value of the program to be detected, it is possible to detect whether the data is consistent. If it is inconsistent, it means that there may be a problem with the currently running data. At this time, the corresponding fourth data can be obtained from the preset backup data and output as the first data, thereby enhancing the data recovery capability.
[0018] Optionally, after determining whether the fifth verification value is consistent with the sixth verification value, the method further includes: when the fifth verification value is consistent with the sixth verification value, confirming to continue running the program to be tested.
[0019] By adopting the above technical solution, by comparing the fifth check value with the sixth check value, it can be confirmed that the data recovered from the external storage chip is consistent with the data currently used by the program to be detected, which ensures that the data has not changed after the reset startup and maintains the consistency of the data. When the fifth check value is consistent with the sixth check value, the program to be detected is selected to continue running, which avoids unnecessary data recovery operations, reduces resource consumption, and improves the reliability and stability of the system.

[0033] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features.

[0036] As ultrasonic heat meters are often deployed in harsh environments such as high temperature, strong magnetic field and strong electric field, their RS485 communication lines are susceptible to external interference such as high pulses. In addition, the heat meter itself may have insufficient anti-electromagnetic interference capabilities, which may cause errors in the application stored in the FLASH memory and even data loss. Such problems may cause abnormal operation of specific functional modules, or even cause the entire system to crash, freeze and restart ineffectively, and other serious consequences.
[0037] At present, the traditional response to such failures is to dismantle the shell of the ultrasonic heat meter and use a professional firmware burning tool to rewrite the firmware into the heat meter's memory. However, in actual operation, since ultrasonic heat meters are usually installed at high altitudes or in narrow pipe wells, this undoubtedly greatly increases the difficulty and danger of on-site disassembly and operation. In addition, manual intervention during the disassembly process often destroys the original sealing and protection measures inside the heat meter, which will reduce the protection level of the heat meter and may also have an adverse effect on its performance parameters, thereby seriously affecting the subsequent stable operation of the heat meter.
[0038] Therefore, how to solve the problem of manual disassembly of ultrasonic heat meters in actual operation. A processing method of an ultrasonic heat meter application provided in an embodiment of the present application is applied to a server. The server of the present application is a platform that provides repair services for ultrasonic heat meters. Figure 1 This is a first flow chart of a method for processing an ultrasonic heat meter application provided in an embodiment of the present application, with reference to Figure 1 The method includes the following steps S101-S105.
[0039] S101: Obtain a first identifier and a first check value of a program to be detected, where the program to be detected is an application program in an ultrasonic heat meter.
[0040] In the above S101, first, when the ultrasonic heat meter leaves the factory, the host computer detection software and RS485 communication tooling are provided to back up the application of the heat meter, so that when the heat meter automatically detects an error in the application during normal operation, the backup data can be used to repair the application. Specifically, it includes: receiving a backup request sent by the host computer, determining the starting address, byte length and second check value according to the backup request; determining the third data according to the starting address and byte length, and obtaining the third check value corresponding to the third data; judging whether the second check value is consistent with the third check value; when the second check value is consistent with the third check value, obtaining the operating status of the external storage chip; if it is determined that the operating status is in a normal state, obtaining the second identifier corresponding to the third data; writing the third data, the second identifier and the second check value into the external storage chip, the external storage chip includes a first corresponding relationship and a second corresponding relationship, the first corresponding relationship is the corresponding relationship between the third data and the second identifier, the second corresponding relationship is the corresponding relationship between the second check value and the third data, and writing the third data into the preset backup data.
[0041] Specifically, the host computer (such as a computer or other control device) sends a backup request to the server through a communication interface (such as USB, network, etc.). The server receives the request and parses out the information such as the starting address, byte length, and second check value. This information is used to specify the data range to be backed up and to verify the integrity of the data. The second check value is obtained by performing a CRC32 check on the program to be backed up, and the program to be backed up is a program determined based on the starting address and byte length. According to the received starting address and byte length, the corresponding data block, i.e., the third data, is located and read in the ultrasonic heat meter application area. Then, a predetermined check value algorithm (such as CRC32, MD5, etc.) is used to calculate the third data to obtain a third check value. This value is used to compare with the second check value later to verify the integrity of the data. The calculated third check value is compared with the received second check value. If the two are consistent, it means that the selected third data meets the backup request, and there is no change during the transmission process, and subsequent operations can be performed. When the second check value is consistent with the third check value, a status query request is sent to the external storage chip, which is a chip specifically used to store backup data in the ultrasonic heat meter, and its English name is EEPROM. The external storage chip responds to the command and returns its current operating status information. This information may include whether it is readable and writable, remaining capacity, error rate, etc. After confirming that the external storage chip is in a normal state, a unique second identifier is assigned to the third data. This identifier may be a byte or other form of unique identifier. For example, the second identifier can be set to 0xAA, the second identifier can be associated with the third data, and the third data, the second identifier and the second check value can be packaged into a data packet. The data packet is written to the specified location in the external storage chip through the communication interface. During the writing process, additional check and error handling operations may be required to ensure the integrity and reliability of the data. In order to facilitate subsequent inquiries about the backup data stored in the external storage chip, a first corresponding relationship and a second corresponding relationship can be established in the external storage chip. The first corresponding relationship is the corresponding relationship between the third data and the second identifier, which is used for subsequent data retrieval and recovery; the second corresponding relationship is the corresponding relationship between the second check value and the third data, which is used for data integrity verification. The third data is added to the preset backup data, which is a storage structure for storing and managing backup data.
[0042] In addition, when the second check value is inconsistent with the third check value, it is confirmed that a backup failure prompt is sent to the upper computer. The backup failure prompt indicates that the selected third data is inconsistent with the backup request. The starting address and byte length of the third data and the third check value must be sent to the upper computer at the same time, so that the corresponding management personnel can understand the cause of the backup failure in time, and take corresponding measures to solve the problem according to the suggestions or reasons in the information.
[0043] Further, after confirming that the corresponding data has been written into the external storage chip according to the backup request, it is also necessary to verify whether the backup data in the external storage chip is correct, which specifically includes: obtaining the target backup data from the external storage chip, calculating the target backup data, and obtaining a fourth check value; judging whether the fourth check value is consistent with the second check value; when the fourth check value is consistent with the second check value, confirming that the third data backup success prompt is sent to the upper computer. Specifically, the target backup data corresponding to the historical backup request is obtained from the external storage chip. The historical backup request refers to the data written to the external storage chip most recently. Taking the above content as an example, the data written to the external storage chip most recently is the third data. At this time, the target backup data is the third data written into the external storage chip. Send a read command to the external storage chip so that it is determined as the target backup data according to the command. Then verify the target backup data to obtain a fourth check value. A suitable check algorithm (such as CRC32) can be selected, which should be the same as the algorithm used to generate the second check value. Use the selected check algorithm to calculate the target backup data to obtain a fourth check value. This value is used for subsequent comparison with the second check value to verify the integrity of the data. Compare the calculated fourth check value with the second check value received previously. If the two are consistent, it means that the target backup data has not changed during the storage and reading process, and the integrity of the data has been verified; when the fourth check value is consistent with the second check value, a prompt message of successful backup is generated. This information usually contains information such as the identification of the backup data, the backup time, the check value, etc., so that the user or the host computer can confirm and record it. Send the prompt message of successful backup to the host computer through the communication interface (such as the network, USB, etc.). The host computer receives and parses this information to confirm the successful completion of the backup operation. When the fourth check value is inconsistent with the fifth check value, a backup failure prompt is generated to prompt that errors and damage occur during the storage and transmission process of the data. If there are multiple backup requests, the data corresponding to each backup request shall be located and compared in turn according to the above content. When the comparison result is correct, the backup data can be written to the external storage chip. Figure 2 shown.
[0044] Furthermore, after completing the backup operation of the application program of the heat meter, the heat meter can be packaged and shipped. After the heat meter is installed in the corresponding position, the heat meter can start working. During the working process, due to the interference of strong magnetism in the installation environment and the communication line, errors or loss of the application program in the heat meter may occur, which may cause the heat meter to be in a dead state or failure. Therefore, it is necessary to judge the operation of the heat meter regularly, and then determine different treatment measures based on the judgment results. Determine whether the first check value of the program to be detected can be obtained; if it is determined that the first check value of the program to be detected cannot be obtained, the watchdog is used to timeout reset the server and run the boot program. Specifically, judging whether the first check value of the program to be detected can be obtained, whether the check value of the running program can be obtained at this time, is a way to judge whether the application is in a running state or a dead state. If the server cannot obtain the first check value of the program to be repaired, it can be assumed that the application program of the heat meter is in a dead state, and then the watchdog is used to timeout reset the server (the application program of the ultrasonic heat meter). Watchdog is a hardware or software function used to monitor the running status of the program. If the system or program does not perform a specific operation (such as feeding the dog) within a predetermined time, the watchdog will trigger a reset or restart operation. Configure the watchdog function in the server, including setting parameters such as the clock source, pre-scaling coefficient, reload value, and enable bit. These parameters determine the conditions and time for the watchdog to trigger the reset operation. When it is determined that the valid first check value of the program to be detected cannot be obtained, it can be considered that the program may be dead. At this time, the watchdog mechanism can be triggered by software or hardware. After the watchdog detects a timeout (that is, no feeding signal is received within the predetermined time), it will perform a reset operation to restart the server and run the boot program. The bootloader is the first program that runs when the server starts. It is responsible for initializing the system hardware, loading the operating system or other necessary programs, and handing over control to the operating system. After the server is reset, the bootloader will start executing to ensure that the application of the ultrasonic heat meter can start and run normally.
[0045] In addition, when it is determined that the first check value of the program to be detected can be obtained, it can be confirmed that the application of the heat meter is currently in operation, but the operation state needs to be judged to determine whether a repair operation is required. The program to be detected is the application running in the ultrasonic heat meter, and then a unique identifier, that is, the first identifier, is extracted from the program to be detected. This identifier is used to distinguish the current program module or data block. At the same time, the program to be detected is calculated to obtain the first check value. At this time, the first check value is obtained by calculating the program to be detected using the CRC32 algorithm.
[0046] S102: Determine whether a first identifier exists in a preset identifier table, where the preset identifier table is a table composed of identifiers corresponding to preset backup data.
[0047] In the above S102, after obtaining the first identifier of the program to be detected, a preset identifier table needs to be obtained from the external storage chip. The preset identifier table is a data table storing preset backup data and its corresponding identifiers. The preset backup data refers to a set of backup data stored in the external storage chip. The first identifier is searched in the preset identifier table. The purpose of searching the first identifier is to determine whether the program to be detected has a backup in the external storage chip.
[0048] S103: When the first identifier exists in the preset identifier table, determine whether the first check value is consistent with the preset check value.
[0049] In the above S103, when the first identifier exists in the preset identifier table, it is confirmed that there is a backup of the program to be detected in the external storage chip, so the backup data corresponding to the first identifier is obtained from the external storage chip, and the preset check value corresponding to the backup data is obtained. At this time, the preset check value refers to the check value corresponding to the identifier in the external storage chip that is the same as the first identifier. The first check value corresponding to the program to be detected is compared with the preset check value, and the comparison is to determine whether the current program to be detected is in a normal working state or an abnormal working state.
[0050] When the first identifier does not exist in the preset identifier table, it is confirmed that there is no backup of the program to be detected in the external storage chip, and then the identifier of the program to be detected is continuously obtained, and the re-obtained identifier is compared with the preset identifier table.
[0051] S104: If it is determined that the first verification value is inconsistent with the preset verification value, obtaining first data corresponding to the preset verification value from the preset backup data.
[0052] In the above S104, when the first check value is inconsistent with the preset check value, it is confirmed that the program to be detected has changed and repair measures need to be taken for the program to be detected. The server can be restarted through the reset program, and the boot program is run to start the repair operation, which specifically includes: using the reset program to reset and start the server, and run the boot program, and obtain the fifth check value from the external storage chip again; obtain the sixth check value of the program to be detected again; determine whether the fifth check value is consistent with the sixth check value; when the fifth check value is inconsistent with the sixth check value, confirm to obtain the fourth data corresponding to the fifth check value from the preset backup data, and output the fourth data as the first data.
[0053] Specifically, ensure that the reset program has been correctly installed and configured on the server. The reset program may be a specific software tool used to restart the server when it is determined that the program to be detected has changed. The execution of the reset program is triggered by means of a server management interface, a command line tool, or a physical button. The reset program will shut down all running services and applications on the server and save necessary data (if possible). The server will shut down and restart, and run the boot program at the same time. The boot program is responsible for initializing the system hardware, loading the operating system or other necessary programs, and handing control to the operating system. After restarting again, it will identify and connect to the external storage chip, which stores the previously backed up data and corresponding check values. Before obtaining the fifth check value from the external storage chip, it is also necessary to determine whether the external storage chip is in normal operation and the data corresponding to the first identifier has been backed up in the external storage chip. If the external storage chip is in normal operation and the data corresponding to the first identifier has been backed up in the external storage chip, the backup data corresponding to the first identifier is read from the external storage chip, and the fifth check value corresponding to the backup data is obtained. Reload the program to be detected, and use the same check value algorithm to calculate the loaded program to be detected to obtain a sixth check value. Compare the fifth check value with the sixth check value. If the two check values are consistent, it means that the backup data has not changed during the storage and reading process, and the program to be tested is consistent with the version at the time of backup. If the two check values are inconsistent, it means that the program to be tested may be damaged. After determining that the fifth check value is inconsistent with the sixth check value, the data block corresponding to the fifth check value in the preset backup data, that is, the fourth data, will be located. The fourth data will be restored from the backup data and output as the current first data.
[0054] In addition, when the fifth check value is consistent with the sixth check value, it is confirmed to continue running the program to be tested. Then the program to be tested is complete and not damaged, and the program to be tested can be directly jumped to and run.
[0055] S105: Replace the second data according to the first data, the second data being data corresponding to the program to be detected.
[0056] In the above S105, when it is determined that the first check value is inconsistent with the preset check value, and after the software is reset, the fifth check value obtained again is inconsistent with the sixth check value, it can be confirmed that the program to be detected is abnormal and the abnormality needs to be repaired. The data block associated with the preset check value, that is, the first data, can be obtained from the preset backup data of the external storage chip. The first data is extracted from the backup data to replace the damaged data. First determine the second data corresponding to the program to be detected, and the second data can also be understood as the current data. Replace the first data to the second data position in the program to be detected. This usually involves operations such as modifying the data structure in the memory, writing files, or updating the database. After the replacement is completed, the replaced data is recalculated to obtain the check value, and the check value is compared with the check value in the backup data. According to the comparison result, it is verified whether the replacement is successful to ensure the integrity and consistency of the data. After the subsequent verification that the replacement is successful, if the check value is consistent with the backup check value, you can jump and run the program to be detected. If Figure 3 shown.
