[0002] The Scada system manages a large number of sensor devices, some of which have large memory and support mains electricity. Such devices can be upgraded by downloading upgrade packages through URLs. However, there are a large number of existing devices in the gas industry, which have small memory and are powered by batteries. They do not support downloading through URLs and have poor support for the server to actively push upgrade packages.

[0003] The above contents are only used to assist in understanding the technical solution of the present invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0004] The main purpose of the present invention is to provide a gas equipment firmware upgrade method, device, equipment and storage medium, aiming to solve the technical problem that a large number of existing devices in the gas industry do not support downloading upgrade packages via URLs and have poor support for the server's active push of upgrade packages.

[0005] To achieve the above object, the present invention provides a method for upgrading the firmware of a gas device, the method comprising the following steps:

[0006] Send firmware upgrade instructions to each gas device through the Scada system;

[0007] Receiving current firmware information fed back by each gas device based on the firmware upgrade instruction;

[0008] Creating an upgrade task, and determining a list of gas devices to be upgraded corresponding to the upgrade task according to the current firmware information;

[0009] Determine the firmware upgrade mode of each gas device to be upgraded, and select an upgrade package according to the firmware upgrade mode, wherein the firmware upgrade mode includes a first firmware upgrade mode and a second firmware upgrade mode. If the second firmware upgrade mode is used, select the upgrade package according to the difference between the current firmware of the gas device to be upgraded and the new upgrade firmware;

[0010] Initiate an upgrade task, and distribute the upgrade package based on the list of gas equipment to be upgraded through the Scada system;

[0011] The upgrade results fed back by each gas device to be upgraded after completing the firmware upgrade are received, and the Scada system updates the status of the upgrade task to complete the firmware upgrade.

[0012] In some embodiments, the sending of firmware upgrade instructions to each gas device through the Scada system includes:

[0013] Get the status information of each gas device;

[0014] Extracting a corresponding status identifier from the status information;

[0015] The status identifiers are compared with the status identifiers stored in the identifier library respectively. If it is determined through the comparison that the gas device is in an online state, a firmware upgrade instruction is sent to the gas device in the online state through the Scada system.

[0016] In some embodiments, determining the list of gas devices to be upgraded corresponding to the upgrade task according to the current firmware information includes:

[0017] Comparing the current firmware information with the target firmware information;

[0018] If the versions of the current firmware information and the target firmware information are inconsistent, and the gas device supports the functions after the upgrade package is upgraded, the corresponding gas device is determined to be a gas device to be upgraded, and a corresponding list of gas devices to be upgraded is generated.

[0019] In some embodiments, if the second firmware upgrade method is used, selecting an upgrade package according to the difference between the current firmware of the gas device to be upgraded and the new upgrade firmware includes:

[0021] Determine a byte difference within the first region, store the byte difference in a difference memory block, and store all bytes within the second region as a whole in an additional memory block;

[0022] Adding the bytes in the current firmware and the byte differences in the first area byte by byte, and adding the bytes of the additional memory block to the end of the byte segment after the addition, to obtain a first differential packet;

[0023] Generate a second differential packet based on the first differential packet, and compress the second differential packet to obtain a target differential packet;

[0024] A corresponding upgrade package is selected based on the target differential package.

[0025] In some embodiments, generating the second differential packet based on the first differential packet includes:

[0026] Determine that the zero elimination coding pointer points to the starting position of the difference memory block in the first difference packet;

[0027] If the starting position is a zero byte, statistical zero elimination encoding is performed on the continuous zero byte sequence, and a flag byte is inserted;

[0028] If the starting position is a non-zero byte, shift the non-zero byte backward by one position;

[0029] Return to the step of determining that the zero elimination coding pointer points to the starting position of the difference memory block in the first difference packet until all bytes of the difference memory block are processed to obtain a second difference packet.

[0030] In some embodiments, compressing the second differential packet to obtain a target differential packet includes:

[0031] Setting two sliding windows of the same size, sliding the second differential packet through the two windows in sequence, putting the processed data in the differential packet into the first window, and putting the unprocessed data into the second window, wherein the first window is used as a dictionary;

[0032] Starting from the first character string of the second window, the processing is performed in sequence according to the byte order;

[0033] When processing the current string, the first three bytes of the current string are used to search whether there is a matching string in the dictionary;

[0034] If there is a matching string, the longest string is determined by matching, the matching length is used to replace the longest string for output, and the string is put into the dictionary;

[0035] If there is no matching string, the current character is output and placed in the dictionary;

[0036] A target differential packet is obtained according to the data contained in the dictionary obtained after the processing of the second window is completed.

[0037] In some embodiments, the method further comprises:

[0038] After receiving the upgrade package, each gas device to be upgraded parses the upgrade package and determines the upgrade file start identifier, upgrade package data type and upgrade data based on the parsing result;

[0039] Each gas device to be upgraded performs a legitimacy check based on the upgrade file start identifier, and when the upgrade file start identifier is a legal start identifier, performs a consistency comparison of the upgrade package data type, and performs a firmware upgrade according to the upgrade data after the upgrade package data type is met.

[0051] Figure 2 This is a structural block diagram of the first embodiment of the gas equipment firmware upgrade device of the present invention.

[0052] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0053] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0054] The embodiment of the present invention provides a method for upgrading the firmware of a gas device, referring to Figure 1 , Figure 1 The figure is a flow chart of a first embodiment of a method for upgrading the firmware of a gas device according to the present invention.

[0055] In this embodiment, the gas equipment firmware upgrade method includes the following steps:

[0056] Step S10: Sending firmware upgrade instructions to each gas device via the Scada system.

[0057] In this embodiment, the executor of this embodiment is a gas equipment firmware upgrade device, wherein the gas equipment firmware upgrade device has functions such as data processing, data communication and program running. The gas equipment firmware upgrade device can be a computer terminal device or other network device, and of course it can also be other devices with similar functions, and this embodiment does not limit this.

[0058] It should be noted that the Scada system manages a large number of sensor devices, some of which have large memory and support mains electricity. Such devices can be upgraded by downloading upgrade packages through URLs. However, there are a large number of existing devices in the gas industry, which have small memory and many of which are powered by batteries. They do not support downloading through URLs and have poor support for the server to actively push upgrade packages.

[0059] In order to solve the above technical problems, this embodiment sends firmware upgrade instructions to each gas device through the Scada system, receives the current firmware information fed back by each gas device based on the firmware upgrade instruction; creates an upgrade task, and determines the list of gas devices to be upgraded corresponding to the upgrade task according to the current firmware information; determines the firmware upgrade method of each gas device to be upgraded, and selects the upgrade package according to the firmware upgrade method; starts the upgrade task, and sends the upgrade package based on the list of gas devices to be upgraded through the Scada system; receives the upgrade results fed back by each gas device to be upgraded after completing the firmware upgrade, and the Scada system updates the status of the upgrade task to complete the firmware upgrade. There is no need to download the upgrade package through the URL method, and the upgrade package is sent using the file transfer function of the Scada system itself, thereby completing the firmware upgrade. Specifically, it can be implemented as follows.

[0060] In the specific implementation, in this embodiment, the firmware upgrade instruction is sent to each gas device through the Scada system, wherein the SCADA (Supervisory Control and Data Acquisition) system is a collection and monitoring system for the Internet of Things.

[0061] It should be noted that before issuing a firmware upgrade instruction, it is necessary to first detect the operating status of each gas device. Specifically, obtain the status information of each gas device; extract the corresponding status identifier from the status information; compare the status identifier with the status identifier stored in the identifier library. If it is determined through comparison that the gas device is online, the firmware upgrade instruction is issued to the online gas device through the Scada system.

[0062] Each status identifier corresponds to an operating status of a gas device, such as online status, offline status, and fault status. The firmware upgrade in this embodiment is for gas devices that are in an online state. Therefore, the gas devices that are in an online state can be determined by comparing the status identifiers. Finally, the Scada system sends firmware upgrade instructions to these gas devices that are in an online state.

[0063] Step S20: receiving current firmware information fed back by each gas appliance based on the firmware upgrade instruction.

[0064] After receiving the firmware upgrade instruction, each gas device will feedback the current firmware information to the Scada system based on the firmware upgrade instruction. The current firmware information is used to determine the subsequent firmware upgrade to avoid repeated delivery of upgrade packages.

[0065] Step S30: creating an upgrade task, and determining a list of gas devices to be upgraded corresponding to the upgrade task according to the current firmware information.

[0066] After receiving the current firmware information of each gas device, the corresponding upgrade task will be created in this embodiment. The upgrade task corresponds to the corresponding list of gas devices to be upgraded, and the upgrade task is in an unfinished state before the firmware upgrade is completed. The gas devices to be upgraded in each gas device can be determined by the current firmware information of each gas device obtained above. The specific process is to compare the current firmware information with the target firmware information; if the current firmware information is inconsistent with the version of the target firmware information, and the gas device supports the function after the upgrade package is upgraded, then the corresponding gas device is determined to be a gas device to be upgraded, and a corresponding list of gas devices to be upgraded is generated.

[0067] It should be noted that in this embodiment, the determination of whether the gas device is a gas device to be upgraded is divided into two dimensions. The first dimension is based on the version. For example, if the current version of the gas device is lower than the latest version corresponding to the target firmware information, the gas device meets the first condition for upgrading. The second dimension is based on whether the current gas device can support the upgraded function. In actual situations, different models of gas devices lead to differences in the functions of the gas devices. For example, some new gas devices have different hardware structures compared to old gas devices, resulting in different supported functions. Therefore, in this embodiment, in order to ensure that the gas device can use all the upgraded functions normally after upgrading, it is necessary to judge through the second dimension. If the upgraded function can be supported, the gas device meets the second condition for upgrading. When the above-mentioned first condition and second condition are met at the same time, the gas device is determined to be a gas device to be upgraded. According to the judgment of all gas devices, a list of gas devices to be upgraded can be finally formed.

[0068] In addition, for gas equipment that meets the first condition but does not meet the second condition, this embodiment can adopt the method of not upgrading to handle it, or it can adopt the upgrade package of relatively low version to upgrade it. This embodiment does not limit the above specific processing methods and can be selected according to actual conditions.

[0069] Step S40: Determine the firmware upgrade method of each gas device to be upgraded, and select an upgrade package according to the firmware upgrade method. The firmware upgrade method includes a first firmware upgrade method and a second firmware upgrade method. If it is the second firmware upgrade method, select the upgrade package according to the difference between the current firmware of the gas device to be upgraded and the new upgrade firmware.

[0070] After determining the gas equipment to be upgraded, the upgrade package needs to be issued in this embodiment. Before issuing the upgrade package, the firmware upgrade method needs to be determined. The firmware upgrade method in this embodiment includes a first firmware upgrade method and a second firmware upgrade method. Specifically, the first firmware upgrade method is to directly replace the old firmware information in the gas equipment to be upgraded with the new firmware information in the upgrade package. For this firmware upgrade method, the completed upgrade package can be directly issued in this embodiment. The second firmware upgrade method is to update the old firmware information by using the difference between the new firmware information in the upgrade package and the old firmware information in the gas equipment to be upgraded.

[0071] In this embodiment, for the second firmware upgrade method, it is necessary to select an upgrade package based on the difference between the current firmware of the gas equipment to be upgraded and the target firmware. Specifically, the first area and the second area between the current firmware and the new upgraded firmware are identified based on byte changes; the byte difference in the first area is determined, and the byte difference is stored in a difference memory block, and all bytes in the second area are stored as a whole in an additional memory block; the bytes in the current firmware and the byte difference in the first area are added byte by byte, and the bytes of the additional memory block are added to the end of the byte segment after the addition to obtain a first differential package; a second differential package is generated based on the first differential package, and the second differential package is compressed to obtain a target differential package; and a corresponding upgrade package is selected based on the target differential package.

[0072] It should be noted that the first area is a similar area, that is, an area where the current firmware and the new upgraded firmware are similar, for example, there are only small changes in some bytes. The byte difference between the current firmware and the new upgraded firmware can be directly determined based on the first area. The second area is a dissimilar area, that is, an area where there are obvious changes between the current firmware and the new upgraded firmware, for example, there is an offset, increase or decrease of a whole segment of bytes. The first differential packet can be obtained by adding the byte difference byte by byte based on the bytes of the current firmware and adding the bytes in the second area to the end of the byte segment after the addition.

[0073] Furthermore, after obtaining the first differential packet, a second differential packet can be obtained based on the first differential packet, specifically by determining that the zero elimination coding pointer points to the starting position of the difference memory block in the first differential packet; if the starting position is a zero byte, statistical zero elimination coding is performed on the continuous zero byte sequence, and a flag byte is inserted; if the starting position is a non-zero byte, the non-zero byte is shifted back one position, and the above two processes are repeated.

[0074] It should be noted that the process of statistical zero elimination coding is to count the number of consecutive 0 bytes, and the statistical value is the copy length. The copy length is used to replace the consecutive 0 bytes to eliminate redundant bytes. The above method can reduce the amount of differential packet data while retaining key information.

[0075] In order to further improve the efficiency of firmware upgrade, the second differential packet also needs to be compressed again in this embodiment. The specific process is to set two sliding windows of the same size, slide the second differential packet over the two windows in turn, put the processed data in the differential packet into the first window, and put the unprocessed data into the second window, wherein the first window is used as a dictionary; starting from the first string of the second window, the processing is performed in sequence according to the byte order; when processing the current string, the first three bytes of the current string are used to search whether there is a matching string in the dictionary; if there is a matching string, the longest string is determined by matching, and the matching length is used to replace the longest string for output and put it into the dictionary; if there is no matching string, the current character is output and put into the dictionary; the target differential packet is obtained according to the data contained in the dictionary obtained after completing the processing of the second window.

[0076] It should be noted that the process of obtaining the second differential package through the first differential package is actually the first compression, so the compressed data is also the processed data, and the first window can be used as a dictionary. For the unprocessed data in the second window, the above-mentioned dictionary-based duplicate check is performed to find the longest string, and the matching length is used to replace the output of the longest string for the longest string. For the string without a match, the string can be regarded as a short string or a small string, and can be directly output.

[0077] Step S50: starting the upgrade task, and issuing the upgrade package based on the list of gas equipment to be upgraded through the Scada system.

[0078] After the upgrade package is distributed, the upgrade task can be started. When the upgrade package is distributed, in this embodiment, the gas equipment to be upgraded does not need to download the upgrade package via a URL. Instead, the upgrade package is directly distributed to each gas equipment to be upgraded through the file transfer function of the above-mentioned Scada system.

[0079] Step S60: receiving the upgrade results fed back by each gas device to be upgraded after completing the firmware upgrade, and the Scada system updates the status of the upgrade task to complete the firmware upgrade.

[0080] It should be noted that after receiving the upgrade package, each gas device to be upgraded parses the upgrade package, determines the upgrade file start identifier, upgrade package data type and upgrade data based on the parsing result, and performs the upgrade after verifying the above information in sequence. Specifically, each gas device to be upgraded performs a legality check based on the upgrade file start identifier, and when the upgrade file start identifier is a legal start identifier, performs a consistency comparison of the upgrade package data type, and performs a firmware upgrade based on the upgrade data after satisfying the upgrade package data type. By performing a legality check on the upgrade file start identifier, the integrity of the upgrade can be guaranteed, and by performing a consistency comparison on the upgrade package data type, the accuracy of the upgrade package being issued can be guaranteed. Subsequent upgrades can be performed after ensuring the above integrity and accuracy.

[0081] Furthermore, after completing the firmware upgrade, each gas device to be upgraded will provide feedback on the upgrade result, and then the Scada system will update the upgrade task from an unfinished state to a completed update state.

[0082] This embodiment sends firmware upgrade instructions to each gas device through the Scada system, receives the current firmware information fed back by each gas device based on the firmware upgrade instruction; creates an upgrade task, and determines the list of gas devices to be upgraded corresponding to the upgrade task according to the current firmware information; determines the firmware upgrade method of each gas device to be upgraded, and selects an upgrade package according to the firmware upgrade method; starts the upgrade task, and sends the upgrade package based on the list of gas devices to be upgraded through the Scada system; receives the upgrade results fed back by each gas device to be upgraded after completing the firmware upgrade, and the Scada system updates the status of the upgrade task to complete the firmware upgrade. There is no need to download the upgrade package through the URL method, and the upgrade package is sent using the file transfer function of the Scada system itself, thereby completing the firmware upgrade.

[0083] In addition, an embodiment of the present invention further provides a storage medium, on which a gas equipment firmware upgrade program is stored. When the gas equipment firmware upgrade program is executed by a processor, the steps of the gas equipment firmware upgrade method described above are implemented.
