and step S100, carrying out firmware upgrade on the single device, thereby verifying the correctness of the firmware upgrade package.
The method specifically comprises the following steps:
step S110, adding a firmware upgrade package and adding label information and rule information for the firmware upgrade package by the upgrade check end, wherein when firmware upgrade is performed on a single device, the device identification code list in the rule information only has one device identification code.
The tag information includes: the firmware upgrade package comprises an upgradable hardware version number and a software version number of the firmware upgrade package, an MD5 check code of the firmware upgrade package, whether the firmware upgrade package is verified to be correct and a storage address of the firmware upgrade package.
The rule information includes: the start time and end time of a rule, the corresponding firmware version, the list of matched device identification codes, whether the rule is available.
The start time and the end time of a rule are the life cycle of the rule, and the rule is valid only in the life cycle of the rule.
The firmware version corresponding to the rule and the matched equipment identification code list define which equipment is to be upgraded by using the firmware of which version; the device identification code is preferably a mac code.
And step S120, a push _ ota _ worker is an upgrade check end, the upgrade check end checks a rule table of the firmware upgrade package every time period T, judges whether the rule is valid, and sends upgrade information and the firmware upgrade package corresponding to the valid rule to a centalbuffer which is an upgrade buffer end.
The upgrading checking end checks a rule table of the firmware every time period T, judges the validity of the rule according to whether the start time, the end time and the rule of each rule are available, judges which equipment to send the upgrading information of the firmware upgrading packet through the equipment identification code list, packages the firmware upgrading packet and the upgrading information which meet the conditions and sends the firmware upgrading packet and the upgrading information to the upgrading buffer end.
Step S130, the upgrading buffer end sends the firmware upgrading packet and the upgrading information to the upgrading relay end, and the upgrading relay end sends the upgrading information to corresponding equipment according to the equipment identification code in the rule information of the firmware upgrading packet.
The upgrade information includes MD5 check code, upgradeable hardware version number, upgradeable software version number of the complete firmware upgrade package.
The equipment sends the self equipment information to the upgrading transfer terminal, and the upgrading transfer terminal stores the equipment information and updates the equipment information in real time.
The equipment information comprises the equipment identification code of the equipment, the hardware version number and the software version number, each equipment has the unique equipment identification code, and the upgrading transfer terminal finds the equipment matched with the equipment identification code list through the equipment identification code list in the rule information.
Step S140, the equipment receives the upgrading information, and when the upgrading information meets the first preset condition, the equipment downloads the firmware upgrading package.
The first preset condition is as follows: comparing the upgradable hardware version number and upgradable software version number in the upgrade information with the current hardware version number and software version number of the equipment, wherein the hardware version number is consistent, or the current hardware version number of the equipment is higher than the upgradable hardware version number, and the current software version number of the equipment is lower than the upgradable software version number.
And when the upgrading information meets the first preset condition, the current firmware of the equipment needs to be upgraded, and the equipment downloads a firmware upgrading package.
And step S150, after the firmware upgrading package passes the verification, the equipment starts to upgrade the firmware.
The specific method for checking comprises the following steps: the equipment calculates the MD5 check code of the received firmware upgrade package and the MD5 check code in the upgrade information, if the two check codes are consistent, the downloaded firmware upgrade package is complete, and the firmware upgrade is started; if the firmware upgrading package and the upgrading transit terminal are inconsistent, the firmware upgrading package is incomplete, the firmware upgrading cannot be carried out, the equipment downloads the firmware upgrading package from the upgrading transit terminal again, and the integrity of the firmware upgrading package is verified again until the verification is passed.
When the firmware is upgraded, the original file of the equipment to be upgraded can be erased, and the received firmware upgrade package is written in to realize the firmware upgrade.
And S200, after the firmware of the single device is upgraded successfully, upgrading the devices to be upgraded in batches.
The difference between step S200 and step S100 is only that: the device identification code list includes the device identification codes of all the devices to be upgraded, or the device identification codes of all the devices to be upgraded except the device in step S100, and the remaining steps are the same.
The silent upgrading method of the equipment firmware firstly upgrades the firmware of a single equipment, and the equipment can be upgraded in batches after the correctness of the firmware is verified, so that the correctness of the firmware is ensured when the equipment is upgraded in batches; controlling which equipment is upgraded by adding rules; verifying the integrity and correctness of firmware transmission by means of MD 5;
example 2
Fig. 3 illustrates a method for upgrading device firmware in a silent manner according to this embodiment.
Specifically, the method for upgrading the device firmware in a silent manner provided by this embodiment basically adopts the same steps as those in embodiment 1.
The difference lies in that: in step S110, when firmware of a single device is upgraded, the device identification code list includes device identification codes of all devices to be upgraded.
In step S130, the upgrade relay terminal reads an equipment identifier in the equipment identifier list, and sends the upgrade information to the equipment corresponding to the equipment identifier.
One rule for acquiring the device identification code is: the first device identification code in the device identification code list, or the last device identification code in the device identification code list, or a random device identification code in the device identification code list.
Therefore, based on the embodiment, the device identification codes in the device identification code list do not need to be input twice, and the firmware upgrade verification of a single device and the upgrade of equipment in batches can be completed by using the same device identification code list, so that the operation flow is reduced, and the verification efficiency of the upgrade method is further improved; in addition, if the equipment identification code is acquired in a random form, the correctness verification of the firmware upgrade package is more accurate, and the error rate is low.
