Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used for explaining the relative position relationship between the components, the motion situation, and the like under a certain posture (as shown in the drawing), and if the certain posture is changed, the directional indications are changed accordingly.
Along with the popularization of the internet of things equipment, more and more company teams are added into the development and production of the internet of things equipment, wireless network module firmware (wifi module firmware) of the internet of things equipment is produced in a factory, once a fault which is not found before the wireless network module firmware appears is found, a production accident occurs, the wireless network module firmware needs to be replaced in batches at this time, generally, each equipment is matched with a network, then the wireless network module firmware is used for inquiring an upgrade package on a cloud upgrade file server in a unified mode, and then the wireless network module is upgraded on line (namely, the OTA upgrade is carried out on the wireless network module). This method is not problematic for OTA upgrade of a single device, but in the case of a large number of devices, hundreds or thousands of devices, each device needs to be networked with a specific application program and then perform OTA upgrade, which is very slow, if network conditions are good, each device needs to allocate network time for 2 minutes, OTA upgrade time for 5 minutes, the successful upgrade time of the device is 7 minutes per device, if there are one thousand devices, it takes 7000 minutes, i.e. 116 hours, and if one person works for 12 hours each day, it takes 10 days to complete all the upgrade of the devices. In short, since a lot of time is consumed in the distribution process of the equipment, the time cost required for upgrading the equipment is greatly increased, and the on-time delivery of the product is seriously affected.
Based on the above defects of the prior art, the invention provides an upgrading method of a wireless network module, which is characterized in that a router specially used for equipment upgrading is preset, automatic network distribution of equipment is realized through the router, then a preset local area network protocol address is accessed, a firmware upgrading file stored on the address is obtained, and after the validity of the firmware upgrading file is determined through a series of verification processes, the upgrading file is adopted to realize automatic upgrading of the wireless network module. According to the invention, the wireless network module needing to be upgraded does not need to be manually distributed, so that a large amount of human resource cost can be effectively saved.
As shown in fig. 1, the present embodiment provides a method for upgrading a wireless network module, where the method includes the following steps:
and S100, connecting a target router, and acquiring a firmware upgrading file according to the target router.
Specifically, for various existing upgrading methods, the embodiment adopts an OTA upgrading technology to upgrade the device or the terminal to repair defects or provide better functions. OTA upgrade technology, Over-the-air technology. The current implementation manner of OTA upgrade usually uses a file server as an upgrade server, on which an upgrade configuration file or an upgrade package is placed, and the device end needs to download and analyze the upgrade configuration file for upgrade after the distribution network. In order to complete the distribution network of the equipment to be upgraded, a target router special for the distribution network of the equipment to be upgraded is preset in the embodiment, the equipment to be upgraded needs to be connected to the target router for the distribution network at first, and then the server placed with the firmware upgrade file can be accessed through the target router and the firmware upgrade file is obtained.
As shown in fig. 2, in an implementation manner, the step S100 specifically includes the following steps:
step S110, starting a wireless network module, and scanning according to the wireless network module and a preset service set identifier;
step S120, when a target router is scanned, connection is established with the target router through the preset service set identification and the preset connection password;
step S130, accessing a preset file server through the target router, and acquiring a firmware upgrade file stored on the preset file server.
Specifically, in order to implement an automatic network distribution process of a wireless network module, in this embodiment, a service set identifier and a password are stored in advance in the wireless network module of a device to be upgraded, where the service set identifier is used to search for a target router, and the password is used to establish a data connection with the target router. When the equipment is started, a wireless network module is started firstly, then the wireless network module is controlled to scan according to a preset service set identifier, and a target router for a distribution network is searched. When a target router is scanned, the equipment to be upgraded sends a connection request to the target router, wherein the connection request comprises self equipment information, a service set identifier of the target router needing to be connected and a preset connection password, and after the target router obtains the connection request, the target router generates corresponding response information based on the connection request and sends the response information to the equipment to be upgraded, so that a data connection relation between the equipment to be upgraded and the target router is established. After the connection is established, the equipment to be upgraded can realize communication in the local area network through the target router, and then establish data communication with a preset file server and acquire a firmware upgrading file stored on the preset file server.
In order to obtain a firmware upgrade file stored on a preset file server, in an implementation manner, a preset local area network protocol address may be accessed through the target router, request information is sent to a preset file server on the preset local area network protocol address, then, according to response information generated based on the request information, response information generated based on the request information is finally obtained, and a firmware upgrade file stored on the preset file server is obtained according to the response information. For example, in a specific implementation, a notebook computer may be connected to the target router, and the address of the notebook computer is set as a static lan network protocol address: 192.168.1.253, statically assigning LAN IP addresses means assigning a fixed IP address to each computer, which is convenient for management and avoids the cumbersome process of identity authentication that the user must perform each time he logs on. Then, a preset File Server (Http File Server) is opened on the computer, and the firmware upgrade File is placed on the preset File Server. And after the equipment to be upgraded is started, connecting the equipment to the target router and completing the distribution network. Then the device to be upgraded accesses the lan network protocol address 192.168.1.253 through the target router and sends request information to a preset file server at the address, and after the preset file server obtains the request information, a response packet containing a firmware upgrade file is generated based on the request information and transmitted to the device to be upgraded through a preset path and a file name according to a network protocol (HTTP protocol).
In one implementation, when a target router is not scanned, the scanning duration of the wireless network module is obtained, and the scanning duration is compared with a preset duration threshold. When the scanning time length is less than or equal to the preset time length threshold value, because the scanning time length is too short, whether the target router has a problem or not can not be determined, the wireless network module performs scanning again; when the scanning time is longer than the preset time threshold, it can be judged that the target router has a problem, and the automatic distribution of the equipment can not be realized through the target router, so that the wireless network module is restored to the initial distribution state, and then the equipment to be upgraded is upgraded after being subjected to distribution again.
As shown in fig. 1, the method further comprises the steps of:
and S200, verifying the firmware upgrading file, and taking the verified firmware upgrading file as a backup partition file.
During the network transmission process, data may be more or less erroneous, that is, the data received by the receiving end and the data actually sent by the sending end are inconsistent. In order to ensure that the complete and correct upgrade file is adopted for upgrading, the acquired firmware upgrade file needs to be verified. And only the firmware upgrading file passing the verification can be stored into the partition of the nonvolatile memory of the equipment to be upgraded to serve as a backup partition file for upgrading the firmware of the wireless network module subsequently.
As shown in fig. 3, in an implementation manner, the step S200 specifically includes the following steps:
step S210, acquiring a standard check code attached to the firmware upgrading file;
step S220, calculating the data of the firmware upgrading file through a preset checking algorithm, and taking a result obtained after calculation as a check code to be detected;
and step S230, matching the standard check code with the check code to be detected, judging that the firmware upgrading file passes the check when the standard check code is the same as the check code to be detected, and taking the firmware upgrading file as a backup partition file.
Specifically, in this embodiment, the acquired firmware upgrade file is mainly checked by using a CRC check algorithm (cyclic redundancy check algorithm) or an MD5 check algorithm (information digest algorithm check). The CRC check algorithm mainly uses CRC, i.e., cyclic redundancy check code, and is the most commonly used error-checking check code in the field of data communication, and is characterized in that the lengths of the information field and the check field can be arbitrarily selected. The CRC algorithm is mainly characterized in that polynomial calculation is carried out on data through a data sending end, a calculated CRC code is attached to the back of a data frame and then sent to a data receiving end, the data receiving end carries out polynomial calculation on the received data after acquiring the data frame, the calculated new CRC code is compared with the CRC code attached to the data frame, and if the two CRC codes are equal, the data is not in error in the transmission process; if the two CRC codes are not equal, the condition that transmission errors or loss of data occur in the transmission process is shown. The principle of the MD5 check algorithm is substantially the same as the process of the CRC check algorithm, with the main difference being that the MD5 check algorithm is different from the specific algorithm used by the CRC check algorithm. In order to more accurately check whether a transmission error occurs in a firmware upgrade file received by equipment to be upgraded in a transmission process, in one implementation mode, a CRC (cyclic redundancy check) algorithm and an MD5 (machine direction verification) algorithm can be adopted to perform double verification on the pendant upgrade file, when a CRC check code and an MD5 check code calculated by a local machine of the equipment to be upgraded are respectively the same as a CRC check code and an MD5 check code attached to the firmware upgrade file, the firmware upgrade file is judged to pass the verification, and the firmware upgrade file is stored into a backup partition of a nonvolatile memory of the equipment to be upgraded to serve as a backup partition file.
In one implementation manner, if the standard check code is different from the check code to be detected, it indicates that an error occurs in a current firmware upgrade file in a transmission process, and it is determined that the firmware upgrade file does not pass the check, the wireless network module is restored to an initial distribution network state, so that the equipment to be upgraded performs distribution network again and acquires the firmware upgrade file once again.
As shown in fig. 1, the method further comprises the steps of:
and step S300, carrying out validity verification on the backup partition file, and upgrading the wireless network module according to the backup partition file passing the validity verification.
Before upgrading the wireless network module firmware of the device to be upgraded, the validity of the backup partition file stored in the backup partition needs to be checked, and the method is mainly used for judging whether the system can normally use the backup partition file to upgrade the firmware. Only the backup partition file passing the validity verification can be used for upgrading the wireless network module. In addition, in order to avoid interfering with the execution of the task currently existing on the device to be upgraded, after the validity of the backup partition file is confirmed, the upgrading of the wireless network module firmware can be completed only by restarting the device to be upgraded once. As shown in fig. 4, in an implementation manner, the step S300 specifically includes the following steps:
step S310, acquiring version information and standard version information of the backup partition file;
step S320, matching the standard version information with the version information of the backup partition file to realize validity verification of the backup partition file;
step S330, when the version information of the backup partition file is the same as the standard version information, judging that the backup partition file passes the validity verification, and copying the backup partition file to a main partition of a nonvolatile memory;
and step S340, replacing the original firmware file stored in the main partition according to the backup partition file so as to upgrade the wireless network module.
Specifically, the validity verification in this embodiment is mainly performed by checking the version information of the backup partition file. The version information may include: version number of backup partition file, file name, header information, etc. And matching the version information of the backup partition file with preset standard version information, judging that the backup partition file passes the validity verification when the version information of the backup partition file is the same as the standard version information, and copying the backup partition file to a main partition of a nonvolatile memory. The main partition stores the firmware file currently used by the wireless network module, namely the original firmware file, the original firmware file is replaced by the backup partition file after the backup partition file is copied to the main partition to serve as a new main partition file, and the wireless network module can be automatically upgraded after the system runs the new main partition file. In an implementation mode, if the validity check fails, it indicates that the current firmware upgrade file cannot be normally identified and run by the system, and the wireless network module is restored to the initial distribution network state, and the firmware upgrade file is obtained once again and then upgraded.
The present embodiment provides a complete upgrade process for a wireless network module, which includes the following steps:
step 1, starting a wireless network module, and scanning according to the wireless network module and a preset service set identifier; when the target router is scanned, entering the step 2-4; when the target router is not scanned, step 5-7 is entered.
And 2, establishing connection with the target router through the preset service set identifier and the preset connection password.
And 3, accessing a preset local area network protocol address through the target router, and sending request information to a preset file server on the preset local area network protocol address.
And 4, acquiring response information generated based on the request information, acquiring a firmware upgrading file stored on the preset file server according to the response information, and then entering the step 8.
Step 5, acquiring the scanning time of the wireless network module, comparing the scanning time with a preset time threshold, and entering step 6-9 when the scanning time is less than or equal to the preset time threshold; and when the scanning time length is greater than the preset time length threshold value, the step 15 is entered.
And 6, scanning again through the wireless network module.
And 7, acquiring a standard check code attached to the firmware upgrading file.
And 8, calculating the data of the firmware upgrading file through a preset checking algorithm, and taking a result obtained after calculation as a check code to be detected.
Step 9, matching the standard check code with the check code to be detected, and entering step 10-12 when the standard check code is the same as the check code to be detected; and when the standard check code is different from the check code to be detected, entering step 15.
And step 10, taking the firmware upgrading file as a backup partition file.
And 11, acquiring the version information and the standard version information of the backup partition file.
Step 12, matching the standard version information with the version information of the backup partition file, and entering step 13-14 when the version information of the backup partition file is the same as the standard version information; and when the version information of the backup partition file is not the same as the standard version information, the step 15 is entered.
And step 13, when the version information of the backup partition file is the same as the standard version information, judging that the backup partition file passes the validity verification, and copying the backup partition file to a main partition of a nonvolatile memory.
And step 14, replacing the original firmware file stored in the main partition according to the backup partition file so as to upgrade the wireless network module.
And 15, restoring the wireless network module to the initial distribution network state.
