Detailed Description

The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.

Fig. 1 is a schematic diagram of a method for downloading new version software according to an embodiment of the present invention. The download method is applied to a remote communication device, and the download method can comprise the following steps: step S101, successively downloading a plurality of files in the new version software according to preset downloading times; step S102, reconnecting to a new version server under the condition that one-time downloading is not completed and abnormal downloading occurs; and step S103, when the download identifier is in the first state and the file size of the downloaded times is smaller than the file size of the new version software, continuing to download the new version software by taking the file size of the downloaded times as an offset.

The remote communication device in various embodiments of the present invention may be a 5G remote communication device, such as a 5G remote communication device of a power terminal. The software in The various embodiments of The present invention may be a Firmware Over-The-Air (FOTA) upgrade for a mobile terminal.

The details of the above steps S101 to S103 are explained and explained below.

Before performing the step of successively downloading the plurality of files in the new version of software by the remote communication device (i.e., step S101), the downloading method further includes: acquiring the file size of the new version software from the new version server under the condition of connecting to the new version server; and setting the download flag to the first state and setting the file size of the downloaded times to 0.

Wherein the download is identified as a global variable and stored in the memory (e.g., flash memory). For example, setting a global variable download flag (e.g., download flag) in a flash memory of a remote communication device, wherein the download flag (e.g., download flag) indicates that the remote communication device is in a download state when in a first state (e.g., download flag=1); when the download flag (e.g., download flag) is in the second state (e.g., download flag=0), it indicates that the remote communication device is in the non-download state. Specifically, a download flag of 0 indicates that the remote communication device is not downloading a file task at the current time, and 1 indicates that the remote communication device is downloading a software version at the current time.

If the remote communication device is connected to the new version server (e.g., master station), the remote communication module obtains the file size N of the new version software from the master station through an FTP command, and determines the file size of a single download (typically 512 or 1024) according to N and the preset number of downloads, at which time the download flag is set to 1 and the received file size (size) is set to 0.

Of course, in other embodiments, the file size of the new version of software may be obtained in other manners that exist.

Step S101, a plurality of files in the new version software are downloaded successively according to preset downloading times.

For step S101, the successively downloading the plurality of files in the new version software according to the preset number of downloads may include: and successively downloading a plurality of files in the new version software in an HTTP mode or an FTP mode according to preset downloading times.

The downloading method may further include: under the condition that each downloading is completed, checking the files downloaded each time; and storing the file of each download in a corresponding position in a spare area in a memory of the remote communication device and updating the file size of the downloaded times under the condition that the file of each download passes the verification.

Taking a single download file size 1024 as an example, the remote communication device downloads a new version of the file by FTP in 1024 units, stores the file of each download in a corresponding location in a spare area in a memory (e.g., flash memory) of the remote communication device after the CRC check of the file of each download is passed, and modifies the received file size (size) to size+1024. Thereafter, the file content is downloaded with 1024 as an offset, and the size is modified to size+1024 each time the downloaded file CRC check passes.

Step S102, in the case that one download is not completed and an abnormal download condition occurs, the new version server is reconnected.

The abnormal downloading condition is various conditions that the downloading process cannot be performed normally, for example, abnormal conditions such as power failure or network abnormality (for example, the network signal is lower than a threshold value) and the like are restarted.

Specifically, whether the current downloading process of the new version software is completed is judged, and if the remote communication device is powered off or other abnormal downloading conditions occur before the current downloading process of the new version software is completed, the remote communication device is restarted to be reconnected with the new version server (e.g. a master station).

Step S103, when the download identifier is in the first state and the file size of the downloaded times is smaller than the file size of the new version software, continuing to download the new version software by taking the file size of the downloaded times as an offset.

Wherein the first state (e.g., download flag of 1) indicates that the remote communication device is in a download state.

Specifically, whether the download flag is 1 is determined, if the download flag is still 1, the file size completely received in each download process is valid, whether the received file size is N is determined, and if the received file size is smaller than N, the new version software is continuously downloaded by taking the received file size as an offset. That is, when the remote communication device is powered on to start normal network access, the download flag and the full received file size are queried, and after the remote communication device is connected to a new version server (e.g. a master station), if the download flag is 1 and the received file size is smaller than N, the new version is continuously downloaded by taking the size stored in the flash as an offset, without downloading from the beginning. Thereafter, the exception may be handled in the same manner.

The downloading method may further include: checking the file downloaded last time under the condition that the download identifier is in the first state and the file size of the downloaded times is equal to the file size of the new version software; and storing the last downloaded file in a corresponding position in the spare area and placing the download identifier in a second state under the condition that the last downloaded file passes the verification.

Wherein the second state (e.g., download flag of 0) indicates that the remote communication device is in a non-download state.

Specifically, after the remote communication device is connected to a new version server (e.g., a master station), if the download flag is 1 and the size of the received file is equal to N, performing CRC check on the file downloaded last time, after the CRC check of the file downloaded last time passes, storing the file downloaded last time in a corresponding location in a spare area in a memory (e.g., a flash memory) of the remote communication device, and setting the download flag to 0, and at the same time, modifying the size (size) of the received file to N. The remote communication module software version downloading process is completed.

In particular, the downloading process of the new version software executed by the remote communication device will now be explained and explained by taking fig. 2 as an example.

As shown in fig. 2, the process of downloading the new version of software executed by the remote communication device may include steps S201-S210. In fig. 2, "Y" represents "yes" and "N" represents "no".

Step S201, register with network and judge whether register is successful, if yes, execute step S202; otherwise, the process continues to step S201.

The remote communication device connection registers with the network (e.g., private or public network), which is equivalent to a successful registration (attach).

Step S202, connecting the new version server and judging whether the connection is successful, if yes, executing step S203; otherwise, the step S202 is continued.

Step S203, the file size N of the new version software is obtained.

In step S204, the download flag is set to 1, the received file size is set to 0 and the single download file size is determined to be 1024.

Step S205, executing the current download and judging whether the current download is completed, if yes, executing step S206; otherwise, step S207 is performed.

In step S206, the files downloaded at the current time are sequentially stored in the corresponding positions in the flash and the size=size+1024 is updated.

Step S207, reconnecting to the new version server after the abnormal downloading condition.

For example, upon a special restart or a power outage.

Step S208, determining whether the download flag=1 is satisfied, if yes, executing step S209; otherwise, ending.

Step S209, determining whether the received file size=n is true, if yes, executing step 210; otherwise, step S205 is performed.

Step S210, determining that the downloading of the new version software is completed, setting the download flag to 0, setting the update flag to 1 and setting the update count to 0.

After power failure or abnormality occurs in the process of online downloading of the software version by the remote communication device, the online downloading function after re-powering can not be affected by the abnormality, and the online downloading is continued based on the files stored in the backup area in the flash until the successful downloading of the software version is completed

In summary, the method and the device creatively download a plurality of files in the new version software successively according to the preset download times; then, in the case that the one-time downloading is not completed and an abnormal downloading condition occurs, reconnecting to the new version server; finally, under the condition that the download identifier is in a first state and the file size of the downloaded times is smaller than the file size of the new version software, continuing to download the new version software by taking the file size of the downloaded times as an offset, wherein the first state indicates that the remote communication device is in a downloading state. Therefore, when the downloading process is abnormal, the invention can continuously download the new version software on line by taking the size of the downloaded file as the offset, and is not influenced by the abnormal condition.

An embodiment of the invention provides an upgrading method of new version software, which is applied to a remote communication device. The upgrading method comprises the following steps: s1: judging whether the upgrading identifier is in a first state, wherein the first state indicates that the remote communication device is in an upgrading state; s2: judging whether the upgrading times are smaller than preset upgrading times or not under the condition that the upgrading mark is in the first state; s3: loading new version software from a standby area in a memory of the remote communication device when the upgrade times are smaller than the preset upgrade times, wherein the new version software is downloaded according to the downloading method of the new version software; s4: and under the condition that the abnormal loading condition occurs in the loading process of the new version software, updating the upgrading times, and executing S1, S2 and S3.

Wherein the upgrade identification (e.g., update flag) and the number of upgrades (update count) are global variables and stored in the memory (e.g., flash memory). The two variables are initialized to 0, and the maximum value of the update count can be set according to actual needs (for example, the maximum value is 3), namely, the update is not updated after 3 times of update failure, and the downloaded new version is deleted. For example, setting a global variable upgrade flag (e.g., update flag) in a flash memory of a remote communication device, wherein when the upgrade flag (e.g., update flag) is in a first state (e.g., update flag=1), it indicates that the remote communication device is in an upgrade state; an upgrade flag (e.g., update flag) is in a second state (e.g., update flag=0), indicating that the remote communication device is in a non-upgraded state.

When the downloading of the new version software is completed, the update flag is set to be 1, which means that the remote communication device needs to upgrade the software version in the next restarting or power-off; and update flag=0 indicates that the remote communication device does not need to upgrade the software version at the next restart or power down. And, the update count (update count) is valid only when the update flag is 1.

The abnormal loading condition is various conditions that the loading process cannot normally be performed, for example, the abnormal condition such as power failure or loading environment (e.g. temperature) is restarted.

Specifically, first, it is judged whether update flag=1 is established or not by S1; then, in the case where update flag=1 is established, it is judged by S2 whether update count <3 is established; then, under the condition that update count <3 is met, loading the new version software from a standby area in a flash memory through S3; finally, under the condition that the abnormal loading condition occurs in the loading process of the new version software, updating the update count=update count+1 through S4, and executing S1, S2 and S3.

In an embodiment, the upgrade method may further include: and under the condition that the loading process of the new version software is completed, replacing original edition software in a main area in the memory with the new version software, and deleting the new version software in the spare area.

The upgrade method may further include, at the same time or after deleting the new version of software in the spare area: setting the upgrade flag to a second state, wherein the second state indicates that the remote communication device is in a non-upgraded state; and setting the number of upgrades to 0.

Specifically, if no abnormal loading condition occurs in the new version loading process (i.e. the new version is successfully loaded), deleting original edition software stored in a main area in the flash memory, storing the new edition software to a corresponding position of the main area, and then deleting a new edition file in a standby area. At the same time or later, update flag is set to 0, and also update count is set to 0.

In an embodiment, the upgrade method may further include: loading master software from a main area in the memory in the event that the upgrade identification is in a second state, wherein the second state indicates that the remote communication device is in a non-upgrade state.

That is, when it is determined that Update flag=0 through S1, it indicates that the remote communication device is in a non-upgrade state (i.e., no upgrade of software is required), at this time, the original edition of the software may be loaded from the main area in the flash memory.

In an embodiment, the upgrade method may further include: setting the upgrade flag to the second state when the number of upgrades is equal to the preset number of upgrades, wherein the second state indicates that the remote communication device is in a non-upgrade state; and setting the number of upgrades to 0.

The upgrade method may further include: after a restart, loading master software from a main area in the memory; and deleting the new version software in the spare area.

It is known from S4 that update count=update count+1 if the version upgrade is unsuccessful. Then, steps S1-S2 are performed, for example, if it is determined that update count=3 through S2, the upgrade is failed 3 times, the upgrade is terminated, and the update flag is set to 0. After the remote communication device is powered down and restarted, original edition software can be loaded from a main area in the flash memory, the original edition software stored in the main area is continuously used, and new edition software of the standby area is deleted.

The upgrading process of the new version software executed by the remote communication device will now be explained and explained by taking fig. 3 as an example.

As shown in fig. 3, the upgrade process of the new version software executed by the remote communication device may include steps S301-S311. In fig. 3, "Y" represents "yes" and "N" represents "no".

In step S301, the remote communication device is powered on.

Step S302, loading a BootLoader.

The loading and starting task of the whole system is completed by the BootLoader. For example, in most embedded systems, the system typically starts executing at address 0x00000000 at power-up or reset, and the BootLoader program of the system is typically arranged at this address. Briefly, bootLoader is a small piece of program that runs before the user program runs. Through the applet, the hardware device can be initialized, and the memory space can be initialized, so that the software and hardware environment of the system is brought into a proper state, and the correct environment is prepared for finally calling the kernel of the operating system.

Step S303, judging whether update flag=1 is satisfied, if yes, executing step S304; otherwise, step S305 is performed.

Step S304, judging whether the update count <3 is true, if yes, executing step S307; otherwise, steps S310-S311 are performed.

Step S305, the original version of the software of the main area is loaded.

Step S306, judging whether the new version of software of the loading standby area is successful, if yes, executing steps S307-S308; otherwise, step S309 is performed.

In step S307, both update flag and update count are set to 0.

Step S308, deleting original version software of the main area, copying new version software to the main area and deleting new version software of the standby area.

Step S309, execute update count++.

In step S310, update flag is set to 1 and update count is set to 0.

Step S311, the original version of the software of the main area is loaded and the new version of the software of the spare area is deleted.

The loading process of the software in the various embodiments of the present invention refers to the upgrading process of the software.

After the remote communication device successfully downloads the software version online, the software version can be updated when restarting next time, if the remote communication device is abnormal in the process, the software updating can not be stopped, and the process can be tried again until the updating is successful. If the upgrade fails due to other problems of the version, the remote communication device can return the original version, so that the normal operation of the module is ensured. The method and the device can improve the probability of downloading version software online, improve the probability of success of online upgrading of the 5G remote communication device, prevent the device from being abnormal during upgrading, and comprehensively realize the online upgrading function of the remote communication device.

With the continuous deep construction of the energy Internet, the intelligent level of the power grid is greatly improved, the power utilization service quality requirement is continuously improved, the production operation of the power grid of a company, the business management and the external customer service are undergoing historical transformation, and the data requirements of the power grid data acquisition and control at all levels, the user information interaction and the like are in explosive growth situations.
