TECHNICAL FIELD

[0001] The present application relates to the technical field of water meter collection and copying, in particular to a remote upgrading method, system and device of a water meter collection and copying equipment. BACKGROUND

[0002] The water meter collection and copying equipment is usually installed in a position not easy to be accessed by a user due to its application environment and application scene. Moreover, since the water meter is an appliance for measuring water flow, its installation environment is usually a position with high humidity such as an underground well and an underground pipeline. The laboratory condition cannot completely simulate the on-site use environment. Once a software problem caused by design failure or specific on-site environment interference occurs, a professional maintenance personnel needs to go to the installation site and enter the underground well to update the program of the collection and copying equipment one by one. This is not only dangerous but also difficult and laborious.

[0003] Therefore, there is a technical problem of low efficiency in upgrading the water meter collection and copying equipment in the prior art. SUMMARY

[0020] The remote upgrade server sends the second data packet to the target set copying device in response to the request for the second data packet from the target set copying device.

[0021] In one possible implementation, the target set copying device is remotely upgraded through the upgrade file, including:

[0022] The target set copying device checks the upgrade file.

[0023] If the check result is correct, the target set copying device erases the original file and writes the upgrade file.

[0048] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0049] The terms “include” and “have” and any variations thereof mentioned in the embodiments of the present application are intended to cover the non-exclusive inclusion. For example, a process, method, system, product or equipment including a series of steps or units is not limited to the listed steps or units, but optionally further includes other steps or units not listed, or optionally further includes other steps or units inherent to the process, method, product or equipment.

[0050] The water meter collection equipment is usually installed in a position which is not easy to be accessed by a user due to its application environment and application scene. Moreover, since the water meter is an instrument for measuring water flow, its installation environment is usually a position with high humidity such as an underground well or an underground pipeline. The laboratory condition cannot completely simulate the field use environment. Once a software problem caused by design failure or interference of a specific field environment occurs, a professional maintenance personnel needs to be installed in the field to enter the underground well to update the program of the collection equipment one by one. This is not only dangerous but also difficult and has a large workload. If the user is abroad, the maintenance personnel even needs to be sent to abroad, which consumes a lot of human and material resources. Moreover, since the collection equipment is usually installed in a closed mode, safety protection modes such as hiding and locking are used. Therefore, the customer needs to cooperate to find the collection equipment, such as providing the installation location. Moreover, the collection equipment cannot be used during the upgrading process. If the upgrading process lasts for a long time, the customer will inevitably have a very poor experience. If the software problem is caused by the specific environment of the field, the test in the laboratory environment cannot completely simulate the problem of the field environment. Therefore, whether the newly updated program is stable needs to be verified by a large number of field conditions. Even, the program needs to be updated for many times to completely solve the problem, which will cause unpredictable economic loss.

[0051] The prior art has a remote upgrading method. For example, a maintenance personnel carries a remote upgrading device to the installation site, then installs the remote upgrading device to the installed equipment, and then realizes the remote upgrading of the installed equipment through the remote upgrading device, thereby avoiding the disassembly and installation process of the equipment and improving the effect of equipment maintenance to a certain extent. However, this method still needs the maintenance personnel to enter the installation site to operate, and the maintenance cost is still high and the efficiency is still low.

[0052] Based on this, the embodiment of the present application provides a remote upgrading method, system and device of a water meter collection equipment, which can alleviate the technical problem of low efficiency of upgrading the water meter collection equipment in the prior art.

[0053] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0054] Figure 1 A flowchart of a remote upgrading method of a water meter collection equipment provided by the embodiment of the present application is shown in the figure. The method can be applied to a remote upgrading system of a water meter collection equipment. As shown in the figure, the method comprises the following steps. Figure 1

[0055] Step S110, determining a target collection equipment in an online state.

[0056] For example, as shown in the figure, the method comprises the following steps. Figure 2 ​As shown, the remote upgrade server needs to establish communication with the collection and copying device to realize upgrade. In actual application, some collection and copying devices are limited by application environment and use battery power supply mode. To ensure the service life, the collection and copying device cannot use long connection mode to continuously connect the meter management platform and the remote upgrade server, so the periodic short connection mode is used to connect the server, that is, the remote communication module connects the meter management platform and the remote upgrade server when the collection and copying device needs to report data or reaches the network connection period. After completing the scheduled task, there is no subsequent task to maintain the network, so the network connection is disconnected to reduce power consumption and wait for the next reporting task or network connection task. Other collection and copying devices can use power supply, so the collection and copying device does not need to consider power consumption. After the collection and copying device is started, the remote communication module maintains the network connection of the meter management platform and the remote upgrade server for a long time. Since the network can be connected for a long time, the real-time performance of remote upgrade is higher, and the collection and copying device or the remote upgrade server can actively initiate the remote upgrade process. Remote upgrade of any time and any device can be realized, and upgrade of specified devices and simultaneous upgrade of batch devices can be supported, which can greatly improve the accuracy and efficiency of upgrade.

[0057] As shown in Figure 3 When the collection and copying device is installed and powered in the field, the parallel IP parameters of the remote communication module are configured, and the device is enabled. The collection and copying device starts normal work, periodically collects water meter data, detects that the collection and copying device has a data reporting task or a periodic network connection task, and the remote communication module specifies the connection of the corresponding cloud server according to the already configured parallel IP parameters, and performs corresponding data transmission tasks on different platforms.

[0058] As shown in Figure 2 The maintenance personnel uploads the upgrade file to the remote upgrade server, updates the upgrade file information, and enables the remote upgrade server program update notification function. After the remote upgrade server program update notification function is enabled, the remote upgrade server first detects whether the device is online, for example, the remote upgrade server can send a remote communication handshake request to each collection and copying device, and determine a plurality of target collection and copying devices in an online state through the response result. If the collection and copying device is online, the upgrade file information is actively sent to the device, otherwise, the device is online and then the upgrade file information is sent. The maximum active sending number of the notification function can be customized by the maintenance personnel.

[0059] Step S120, judging whether the target collection and copying device needs to be upgraded.

[0060] As shown in Figure 2As shown, the target set of copy devices in the online state can send a query upgrade file instruction to the remote upgrade server. The remote upgrade server sends the upgrade file version number to the target set of copy devices in response to the request of the target set of copy devices. Alternatively, the remote upgrade server can directly send the upgrade file version number to the target set of copy devices without the request of the target set of copy devices. By comparing the current file version number of the target set of copy devices with the upgrade file version number, it can be determined whether the target set of copy devices needs to be upgraded.

[0061] Step S130, if the judgment result is that the target set of copy devices needs to be upgraded, the upgrade file is sent to the target set of copy devices.

[0062] As shown in the example, Figure 2 If the judgment result is that the target set of copy devices needs to be upgraded, the target set of copy devices can send an upgrade request to the remote upgrade server, and the remote upgrade server can further send the corresponding upgrade file to the target set of copy devices.

[0063] Step S140, the target set of copy devices is remotely upgraded by the upgrade file.

[0064] As shown in the example, Figure 2 After receiving all the upgrade files, the target set of copy devices upgrades itself based on the verified upgrade files, and after the upgrade is completed, the upgrade result can be reported to the remote upgrade server, thereby completing the remote upgrade.

[0065] In the embodiment of the application, the remote upgrade server first establishes wireless communication with each water meter set of copy devices, determines all target set of copy devices in the online state, and then judges whether these target set of copy devices need to be upgraded. If the target set of copy devices needs to be upgraded, the remote upgrade server sends the corresponding upgrade file to each target set of copy devices, so that each target set of copy devices completes remote upgrade through the upgrade file. Compared with the prior art, by storing the latest upgrade program in the remote upgrade server, if the set of copy devices installed in the field cannot solve the problem by using the original program, the corresponding upgrade condition can be set on the remote upgrade server, and then the application program of the set of copy devices is updated through remote upgrade, which facilitates on-site construction and maintenance, improves the efficiency of equipment maintenance, reduces the cost and difficulty of maintenance, and only needs the set of copy devices in the network state to be good, the maintenance and upgrade of the equipment can be carried out without manual intervention, and the stability and customer experience of the equipment are greatly improved, and the technical problem of low efficiency of upgrading the water meter set of copy devices in the prior art is solved.

[0066] The above steps will be described in detail below.

[0067] In some embodiments, the server in the remote upgrading system establishes communication with the target set-copy device, sends the target set-copy device the upgrade file version number, and the target set-copy device compares the upgrade file version number with its own version number, so as to accurately determine whether upgrading is needed. As an example, the remote upgrading system includes a target set-copy device and a remote upgrading server; the step S120 can specifically include the following steps:

[0068] Step a), the remote upgrading server sends the target set-copy device the upgrade file information.

[0069] Step b), the target set-copy device parses the upgrade file information to obtain the upgrade file version number corresponding to the upgrade file information.

[0070] Step c), the target set-copy device judges whether it needs to be upgraded based on its own file version number and the upgrade file version number.

[0071] As an example, as shown in Figure 2 After receiving the upgrade file information transmitted by the remote upgrading server, the target set-copy device can parse the upgrade file information to obtain the upgrade file version number information transmitted by the remote upgrading server, and then compare the version number with its own version number. If the upgrade file version number is higher than its own version number, the target set-copy device requests the remote upgrading server to start upgrading.

[0072] By making the remote upgrading server first send the target set-copy device the upgrade file information, and then the target set-copy device parses the upgrade file information to obtain the upgrade file version number corresponding to the upgrade file information, and then the target set-copy device can judge whether it needs to be upgraded based on its own file version number and the upgrade file version number, so as to accurately determine whether upgrading is needed, and improve the upgrading efficiency.

[0073] Based on the above steps a), b) and c), the target set-copy device actively sends an upgrade request to the remote upgrading server, so that the remote upgrading server can accurately issue the corresponding upgrade file and efficiently complete the remote upgrading. As an example, the step S130 can specifically include the following steps:

[0074] Step d), if the judgment result is that the target set-copy device needs to be upgraded, the target set-copy device sends an upgrade request to the remote upgrading server.

[0075] Step e), the remote upgrading server sends the target set-copy device the upgrade file corresponding to the upgrade file version number in response to the upgrade request.

[0076] As an example, as shown in Figure 2As shown, the target set copying device compares the upgrade file version number with its own version number, and requests the remote upgrade server to start upgrading if the upgrade file version number is higher than its own version number. The remote upgrade server can respond to an instruction allowing upgrading, and send the upgrade file corresponding to the upgrade file version number to the target set copying device.

[0077] By making the target set copying device send an upgrade request to the remote upgrade server if the judgment result is that upgrading is needed, the remote upgrade server can send the upgrade file corresponding to the upgrade file version number to the target set copying device in response to the upgrade request, so that the remote upgrade server can accurately issue the corresponding upgrade file and efficiently complete remote upgrading.

[0078] Based on the above steps d) and e), the remote upgrade server can divide the upgrade file into multiple data packets and send them to the target set copying device multiple times, so as to ensure fast transmission of the file, guarantee error-free transmission, and avoid upgrade failure caused by direct transmission of a large-capacity data packet. As an example, the upgrade file includes multiple data packets; the above step e) can specifically include the following steps:

[0079] Step f), the remote upgrade server sends the first data packet to the target set copying device in response to the upgrade request.

[0080] Step g), the target set copying device stores the first data packet and requests the remote upgrade server for the second data packet.

[0081] Step h), the remote upgrade server sends the second data packet to the target set copying device in response to the request of the target set copying device for the second data packet.

[0082] For example, the target set copying device can send the upgrade request to the remote upgrade server through the following steps: Figure 2As shown, after the remote upgrade server receives the upgrade request of the target set of copy devices, it starts to check the stored upgrade file and decomposes the upgrade file into several small pieces, i.e. multiple data packets. Each small piece can contain 256 bytes of data of the upgrade file. After the decomposition is successful, the target set of copy devices is replied to allow the upgrade response, which contains the upgrade file piece information, such as the number of bytes contained in each small piece, the total number of file pieces, the total CRC16 check code of the upgrade file, etc. After the target set of copy devices receives the response, it parses the upgrade file information contained in the response information, sets the to-be-upgraded condition, and then resets the main control chip of the main body of the target set of copy devices, stays in the upgrade program, and prepares to start the upgrade, and the network connection of the remote upgrade module remains unchanged. The target set of copy devices sequentially requests the upgrade file piece packets, and after the remote upgrade server receives the upgrade file piece packets, it queries the processed upgrade file and sends the corresponding upgrade file piece packets to the target set of copy devices. After the target set of copy devices check the upgrade file piece packets, they are stored in the download program storage area, and then the next upgrade file piece packet is requested.

[0083] By making the remote upgrade server send the first data packet to the target set of copy devices in response to the upgrade request, then the target set of copy devices stores the first data packet and requests the second data packet from the remote upgrade server, and then the remote upgrade server sends the second data packet to the target set of copy devices in response to the request of the target set of copy devices for the second data packet, the remote server can divide the upgrade file into multiple data packets, and send them to the target set of copy devices in small capacity and multiple batches, thereby ensuring the fast transmission of the file, ensuring the transmission without error, and avoiding the upgrade failure caused by directly transmitting a large capacity data packet.

[0084] Based on the above steps d) and e), after the target set of copy devices completely receives the upgrade file, it can check the upgrade file. If the check is successful, the original file is erased and overwritten with the upgrade file, ensuring the success of the upgrade and ensuring the upgrade efficiency. As an example, the above step S140 can specifically include the following steps:

[0085] Step i), the target set of copy devices checks the upgrade file.

[0086] Step j), if the check result is correct, the target set of copy devices erases the original file and writes the upgrade file.

[0087] Step k), if the check result is incorrect, the target set of copy devices discards the upgrade file.

[0088] For example, as shown in FIG. 6, the target set of copy devices can include the following steps: Figure 2As shown, after all the upgrade files are downloaded, the target set copying device starts to check all the data of the fragmented packages. If the check is successful, the target set copying device replies to the remote upgrade server with upgrade success information, then erases the original application program, and writes the upgrade files in the download program storage area into the FLASH space of the original application program. If the check fails, the target set copying device directly discards the upgrade files and continues to execute the original application program. In the case of check failure, the target set copying device can also start the upgrade process again after waiting for a period of time. The target set copying device jumps from the upgrade program to the new application program and starts to run the new application program, and the upgrade is completed this time. The target set copying device starts to work with the new program, detects whether there is a task that needs to maintain the network, and processes the task if there is one. After there is no task that needs to maintain the network, the remote communication module closes the network and reduces power consumption, and then repeats the periodic collection of water meter data, reporting of data, and connection of the network task.

[0089] By making the target set copying device check the upgrade files, if the check result is correct, the target set copying device erases the original files and writes the upgrade files, and if the check result is incorrect, the target set copying device discards the upgrade files, which can ensure successful upgrade and improve the upgrade efficiency.

[0090] In some embodiments, a solution to the upgrade error is also provided to make the function more abundant, for example, when the number of communication failures between the target set copying device and the remote upgrade server is greater than a preset number, the upgrade process is abandoned to avoid other errors caused by continuously attempting to upgrade. As an example, the remote upgrade system includes a target set copying device and a remote upgrade server; the method can also include the following steps:

[0091] Step l), if the communication between the target set copying device and the remote upgrade server fails, the target set copying device re-sends a communication request to the remote upgrade server.

[0092] Step m), if the number of re-sent communication requests is greater than a preset number, the target set copying device gives up the upgrade.

[0093] As an example, as shown in Figure 4 The communication failure can occur in various links. When the communication connection is failed in the initial link, the target water meter set copying device can attempt to re-establish communication with the remote upgrade server, and if the number of re-established communications exceeds a preset number, the target set copying device gives up the upgrade. When the communication is failed when requesting to transmit the files, the target water meter set copying device can attempt to re-establish communication with the remote upgrade server and re-request the abnormal upgrade data fragments, and if the number of requests exceeds a preset number, the target set copying device gives up the upgrade.

[0094] By making the target set of copy equipment resend the communication request to the remote upgrade server in the case of disconnection, and giving up the upgrade when the number of resending is greater than the preset number, the upgrade error can be responded in time, and the upgrade process is abandoned in time, avoiding the occurrence of other errors caused by continuous upgrade attempts.

[0095] Figure 5 A structural diagram of a remote upgrade system of a water meter set copy equipment provided by the embodiment of the application is shown in the figure. Figure 5 As shown in the figure, the system comprises:

[0096] The set copy equipment 501 and the remote upgrade server 502, the set copy equipment 501 comprising a set copy equipment main body 5011 and a remote communication module 5012.

[0097] The set copy equipment main body 5011 and the remote communication module 5012 are connected by a serial port, the remote communication module 5012 and the remote upgrade server 502 are connected by a network, and the remote communication module 5012 is used to realize data transmission between the set copy equipment 501 and the remote upgrade server 502.

[0098] For example, the set copy equipment main body 5011 can adopt an STM32 series single-chip microcomputer, and the STM32 series single-chip microcomputer has a Flash memory module. All the Flash memory modules are arranged in the same linear address space. As shown in the figure, Figure 6 two pieces of complete code with independent running capability are needed to be placed in the set copy equipment main body main control chip, one piece of code is an upgrade program stored in the front end of the Flash space, and the other piece of code is an application program stored in the rear end of the upgrade program, and the two pieces of code do not overlap with each other. The two pieces of code respectively realize different functions and can be independently run, and after the corresponding setting conditions are met, the two pieces of code can jump to each other. The upgrade program occupies a relatively small Flash space and only contains an upgrade function, and the upgrade program can erase and write the code segment of the specified address under the normal working voltage. The application program occupies a larger Flash space and contains the complete business function of the product. After the chip is reset, the upgrade program is entered first, the upgrade program first reads the program to be upgraded identifier from the storage, if the program to be upgraded identifier meets the upgrade condition, the upgrade program continues to stay in the upgrade program and performs subsequent program upgrade operation, otherwise, the chip is directly reset to the application program and the business code of the equipment is executed. An upgrade instruction needs to be defined in the application program, when the upgrade instruction is triggered, the application program sets the program to be upgraded identifier in the storage to meet the upgrade condition, and then the chip is reset to stay in the upgrade program and start the upgrade.

[0099] The remote communication module is an integrated module of various remote communication modes, connected with the collection and copying device through a serial port. The remote communication module also uses an STM32 system single-chip microcomputer. The remote communication module can be compatible with various network modules, such as a 4G network module and an NB-IoT network module. The remote communication module 5012 serves as a bridge for communication between the collection and copying device 501 and the remote upgrade server 502, and has the function of managing multiple parallel IPs. For example, the remote communication module 5012 is set to parallel dual IPs, of which the main IP is configured as a meter management platform of the collection and copying device 501, used for normal business data reporting of the collection and copying device 501, and the slave IP is configured as the remote upgrade server 502, used for remote program updating. The remote communication module 5012 can simultaneously maintain network connections of two IPs, and then agrees on a specific data format with the collection and copying device main body 5011, so as to realize the transmission of data in different data formats to different IPs. For example, the collection and copying device 501 can report meter data to the meter management platform, and can also simultaneously send an instruction for querying an upgrade file to the remote upgrade server 502. The maximum number of parallel IPs of the remote communication module 5012 can be defined by itself. When the collection and copying device 501 needs to report data, the data is transmitted to the meter management platform through the remote communication module 5012 according to the agreed data format, so as to realize the normal meter reading reporting function of the collection and copying device 501. At the same time, the instruction for querying the upgrade file is sent to the remote upgrade server 502 to query whether the current needs to be upgraded. When any IP of the network connections maintained by the remote communication module 5012 transmits data to the remote communication module 5012, the remote communication module 5012 respectively packages the data from different IPs according to the agreed data format, and directly transmits the data to the collection and copying device main body 5011.

[0100] The remote upgrade server 502 can be deployed on a cloud server, used for saving the upgrade program file of the collection and copying device 501, and actively pushing the latest upgrade file information stored at present to the online collection and copying device 501 after the program upgrade notification function of the remote upgrade server 502 is started.
