Description
Technical Field
The invention relates to the field of software upgrading, in particular to a software upgrading method and system of an upper computer.
Background
At present, in wireless devices designed and operated in the fields of M2M (Machine to Machine, communication between machines) and internet of things, a framework combining an upper computer and a wireless module is basically adopted, wherein the wireless module provides a wireless link, and the upper computer realizes application logic. Since the operating environment of the wireless device is usually various and complex, when a problem is found or a change is required during the use process, it is difficult to upgrade the software of the device at this time, and high capital cost and labor cost are required.
for The wireless module, remote upgrade can be performed in a FOTA (Firmware Over-The-Air, Over-The-Air software upgrade of a mobile terminal) mode and The like. However, in some cases, the upper computer software also needs to be updated, and for some larger upper computer software, such as operating a Linux operating system, because the storage space and the operating space of the software are sufficient, the update package can be directly downloaded to the storage space of the upper computer through the wireless module, and then the software is updated.
however, for some smaller upper computers, because the storage space of the upper computers is limited, the software of the upper computers cannot be updated and upgraded by directly downloading the upgrade package, if the upgrade requirement exists, the upgrade package needs to be sent back to a manufacturer or sent to a field for upgrading, and the cost of time, labor, capital and the like is consumed. If the storage space of the upper computer is expanded, the cost of the product is increased, and therefore the market competitiveness and profit of the product are reduced.
disclosure of Invention
The invention aims to overcome the defect that cost is increased due to the fact that a manufacturer needs to be sent back or a person needs to be sent to a field for upgrading or storage space needs to be expanded when the software of an upper computer with limited storage space in the prior art is upgraded, and provides a software upgrading method and a software upgrading system of the upper computer with low cost and high reliability.
the invention solves the technical problems through the following technical scheme:
a software upgrading method of an upper computer is characterized by comprising the following steps:
S1, logging in a server by the wireless module every other time period, wherein a software upgrading package of the upper computer is stored in the server;
S2, the wireless module detects whether the software upgrade package is updated, if yes, the step S3 is executed, and if not, the step S1 is returned;
S3, the wireless module downloads the updated software upgrading package from the server;
S4, the wireless module sends an upgrading instruction to the upper computer;
S5, setting an upgrading flag bit when the upper computer receives the upgrading instruction, and restarting;
S6, judging whether the upgrading flag bit is detected or not in the restarting process of the upper computer, if so, executing a step S7, and if not, ending the process;
and S7, the upper computer reads the updated data of the software upgrading package from the wireless module in a segmented manner, and writes the read data into a program storage area until all the data of the software upgrading package are written.
According to the scheme, the server is logged in through the wireless module, the updated software upgrading package is downloaded, the upper computer reads and writes data of the software upgrading package from the wireless module in a segmented mode until all the data are written into the program storage area, the updating of the whole software upgrading package is completed, and the software upgrading is achieved.
In step S1, the interval between the wireless module logging in to the server may be fixed or random. The specific setting can be according to the demand, and can also be according to the bearing capacity of server. For example, a random time period can be generated by adding a fixed time period and a random time period each time, and the random time period is used as the interval time for logging in the server, so that the time for logging in the server can be prevented from being concentrated, and the pressure of the server can be reduced.
in step S2, the algorithm for the wireless module to detect whether the software upgrade package is updated is the prior art, for example, the software version may be obtained by looking up the name of the software upgrade package in the server, and compared with the software version stored in the wireless module, and whether the software upgrade package in the server is updated is detected according to the comparison result.
in step S3, the wireless module downloads the updated software upgrade package to its own storage space.
in step S5, the upper computer stores the set upgrade flag bit in a storage space such as flash (flash memory) where data is not lost when power is off.
in step S7, the upper computer reads the data of the software upgrade package from the wireless module in segments, and writes the read data into the program storage area after each reading, wherein the data read later covers the data read last time, so that a large storage space is not required for storing the data of the software upgrade package. In addition, the upper computer can set the data position (i.e. offset) and data length of each reading according to the storage space of the upper computer. For example, if the storage space of the memory is small, the length of data read each time can be set to be short; if the storage space of the memory is large, the length of data read each time can be set to be long.
compared with the prior art, the scheme has the advantages that the upper computer reads and writes the data of the software upgrading package from the wireless module in a segmented manner, so that the upper computer can realize software upgrading under the condition of limited storage space, a manufacturer does not need to send the data back or send a person to a field for upgrading, the storage space of the upper computer does not need to be expanded, and the cost is saved.
preferably, step S7 is followed by the following steps: and S8, the upper computer clears the upgrading flag bit and restarts the upgrading flag bit. In step S8, the upgrade flag is cleared after the software of the upper computer is successfully upgraded, so as to prevent the software from being upgraded by mistake when the upper computer is restarted next time.
Preferably, the server further stores an upgrade package information file, wherein the upgrade package information file includes information of a software upgrade package of the upper computer;
If the detection result in step S2 is yes, the following steps are performed:
s23, the wireless module downloads the upgrade package information file from the server, analyzes the downloaded upgrade package information file to obtain a first check value, and executes the step S3;
Step S3 includes the following steps:
S31, the wireless module downloads the updated software upgrading package from the server and calculates a second check value of the downloaded software upgrading package;
S32, the wireless module determines whether the first check value is the same as the second check value, if yes, executes step S4, otherwise, returns to step S1.
in the scheme, the upgrade package information file and the software upgrade package are positioned in the same path in the server. The algorithm for the wireless module to calculate the second check value of the software upgrade package in step S31 is the prior art and will not be described again.
in addition, the communication between the wireless module and the server may be abnormal, which may cause errors in the data downloaded by the wireless module, and therefore, the software upgrade package downloaded by the wireless module needs to be checked, that is, whether the second check value is the same as the first check value is determined, so as to ensure that the data of the software upgrade package downloaded by the wireless module is completely consistent with the data of the software upgrade package in the server.
Preferably, step S1 further includes the following steps: the wireless module sets a first downloading frequency;
step S23 includes the following steps:
s231, the wireless module downloads the upgrade package information file from the server and adds one to the first downloading frequency;
S232, the wireless module judges whether the upgrade package information file is downloaded successfully, if so, step S234 is executed, and if not, step 233 is executed;
S233, the wireless module judges whether the first download times are larger than or equal to a first preset download times, if so, the step S1 is returned, and if not, the step S231 is returned;
s234, the wireless module analyzes the downloaded upgrade package information file to obtain a first check value.
In step S232 of this solution, an algorithm for the wireless module to determine whether the upgrade package information file is successfully downloaded is the prior art, where successful downloading means that the wireless module completes downloading the upgrade package information file. When the downloading fails, the wireless module can download the upgrade package information file from the server for multiple times. The maximum number of downloads is a first preset number of downloads, and the specific value may be set according to the actual situation, for example, may be set to 2 times.
Preferably, step S1 further includes the following steps: the wireless module sets a second downloading frequency;
Step S31 includes the following steps:
s311, the wireless module downloads the updated software upgrading package from the server and adds one to the second downloading frequency;
S312, the wireless module judges whether the software upgrading package is downloaded successfully, if so, the step S314 is executed, and if not, the step 313 is executed;
S313, the wireless module judges whether the second download times are larger than or equal to a second preset download times, if so, the step S1 is returned, and if not, the step S311 is returned;
And S314, the wireless module calculates a second check value of the downloaded software upgrading package.
In step S312 of the present solution, an algorithm for the wireless module to determine whether the software upgrade package is successfully downloaded is also the prior art, where successful downloading means that the wireless module completes downloading the software upgrade package, but does not mean that data of the downloaded software upgrade package is completely consistent with data of the software upgrade package in the server. When the downloading fails, the wireless module can download the software upgrading package from the server for multiple times. The maximum number of downloads is a second preset number of downloads, and the specific value may be set according to the actual situation, for example, may be set to 3 times.
preferably, in step S32, the wireless module determines that the first check value is different from the second check value, and then executes step S313.

and S782, the upper computer judges whether the first check value is the same as the third check value, if so, the step S8 is executed, and if not, the step S7 is returned.
in the scheme, the communication between the wireless module and the upper computer is possibly abnormal, so that the data read by the upper computer is wrong, and therefore, the verification is required after the software of the upper computer is upgraded, and the upgraded software data is completely consistent with the data of the software upgrading package downloaded in the wireless module.

In the scheme, the wireless module can successfully log in the server storing the software upgrading packet and the upgrading packet information file according to the IP address and the port number. Wherein, the IP address and the port number correspond to a unique server together. In addition, some servers may need to enter a username and password to log in, and therefore, the username and password of the server also need to be stored in the wireless module. Some servers may store more files, so that the path for storing the software upgrade package and the upgrade package information file needs to be stored in the wireless module.
