In order to improve the efficiency of firmware upgrading, the application provides a method for firmware upgrading, and the efficiency of firmware upgrading of electronic tags can be improved by realizing batch upgrading of at least one electronic tag. The concrete implementation is as follows: when the total data volume of the upgrading packet in the description information of the packet to be upgraded is larger than the data volume transmitted by each packet, the gateway calculates the total packet number corresponding to the packet to be upgraded based on the total data volume of the upgrading packet and the data volume transmitted by each packet; dividing a packet to be upgraded into N sub-packets, and determining a first sub-packet as a target upgrade packet; when the total data of the upgrading packet is less than or equal to the data volume transmitted by each packet, sub-packets do not need to be divided, and the packet to be upgraded can be determined to be a target upgrading packet; secondly, when a target upgrading packet is sent to the electronic tag, the gateway firstly transmits description information of the packet to be upgraded for M times to the electronic tag, and when the transmission time of the target upgrading packet is reached, the target upgrading packet is transmitted to the electronic tag based on the transmission repetition times of the target upgrading packet in the description information; the electronic tag monitors description information of the package to be upgraded for M times sent by the gateway, receives the target upgrade package when countdown in the description information is finished when the description information is monitored, and upgrades the firmware based on the target upgrade package. The firmware upgrading method can be applied to a firmware upgrading system comprising a gateway and at least one electronic tag, so that the at least one electronic tag can simultaneously receive a target upgrading packet sent by the gateway under the countdown setting, and can be upgraded based on the target upgrading packet, batch upgrading of the at least one electronic tag can be realized, the time cost for sequentially upgrading the firmware of the at least one electronic tag is reduced, and the upgrading efficiency of the firmware upgrading is improved.

It should be understood that, the sequence numbers of the steps in this embodiment do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the inherent logic of the process, and should not constitute any limitation to the implementation process of the embodiment of the present application.

In order to explain the technical solution of the present application, the following description is given by way of specific examples.

Referring to fig. 1, a schematic structural diagram of a firmware upgrade system provided in a first embodiment of the present application is shown. As shown in fig. 1, the firmware upgrade system includes a gateway and L electronic tags, where L is an integer greater than zero.

When the firmware upgrading efficiency of the L electronic tags is improved, data interaction between the gateway and the L electronic tags is needed, firstly, the gateway can divide the package to be upgraded into N sub-packages when the total quantity of the upgrading package in the description information of the package to be upgraded is larger than the data quantity transmitted by each package, so that the transmission of the package to be upgraded is facilitated, and the package to be upgraded is divided into N sub-packages, so that the total package number corresponding to the package to be upgraded can be calculated firstly based on the total data quantity of the upgrading package and the data quantity transmitted by each package, and then the package to be upgraded is divided into N sub-packages based on the total package number, wherein N is the total package number and N is an integer larger than 1. After the packet to be upgraded is divided into N sub-packets, it is determined that the first sub-packet is the target upgrade packet, and transmission of the target upgrade packet is started, where the first sub-packet is a sub-packet in the first transmission sequence among the N sub-packets. When the total number of the upgrade packages is less than or equal to the data volume transmitted by each package, the packages to be upgraded can be directly determined to be target upgrade packages without dividing sub-packages.

Secondly, when the gateway sends a target upgrade package to the electronic tag, the gateway can firstly transmit description information of the package to be upgraded for M times to the electronic tag, and when the transmission time of the target upgrade package is reached, the target upgrade package is transmitted to the electronic tag based on the transmission repetition times of the target upgrade package in the description information;

and the electronic tag monitors the description information of the M times of packages to be upgraded sent by the gateway, and receives the target upgrade package when the countdown in the description information is finished when the description information is monitored. The L electronic tags monitor that the transmission times of the description information are different, and the countdown of correspondingly receiving the target upgrade package is also different, wherein the countdown is the difference between the transmission time of the target upgrade package and the first transmission time consumption, and the first transmission time consumption is the product of the data transmission time between the gateway and the electronic tags and the transmission times of the description information. By adopting the counting method of the countdown, the L electronic tags can be ensured to receive the target upgrade package at the same time, and the firmware is upgraded based on the target upgrade package. The L electronic tags can simultaneously receive the target upgrading packet and upgrade simultaneously, so that the time cost for sequentially upgrading the firmware of the L electronic tags is reduced, and the upgrading efficiency of the firmware is improved.

The gateway can perform unpacking operation on the package to be upgraded when receiving an upgrade instruction sent by the server and the package to be upgraded, and according to the total data volume of the package to be upgraded and the data volume transmitted by each package, judge whether the package to be upgraded needs to be divided into N sub-packages, and generate the description information of the package to be upgraded, and the description information of the package to be upgraded includes the total data volume of the package to be upgraded, the data volume transmitted by each package and a countdown corresponding to the repeated transmission times of the description information, for example, the countdown corresponding to the first sending of the description information is 14998 milliseconds, the countdown corresponding to the second sending of the description information is 14996 milliseconds, and the countdown is used for indicating the electronic tag to receive the target upgrade package after the countdown is finished.

According to the transmission times of the description information, the countdown in the description information may be determined, for example, the gateway transmits the description information of the packet to be upgraded at a frequency of 2 milliseconds per packet, continuously transmits for 10 seconds, and may transmit the description information of the packet to be upgraded 1000 times, if the target upgrade packet is a first sub-packet, and it is set that data of the first sub-packet is transmitted for the first time after the gateway transmits the description information of the packet to be upgraded for 15 seconds, the corresponding countdown in the description information of the packet to be upgraded, which is transmitted by the gateway for the first time, should be 15000-1 × 2 ═ 14998 milliseconds (i.e., the difference between the transmission time of the target upgrade packet and the first transmission time); similarly, the corresponding countdown in the description information of the package to be upgraded, which is transmitted by the gateway for the second time, should be 15000-2 × 2 ═ 14996 milliseconds; similarly, the corresponding countdown in the description information of the packet to be upgraded, which is transmitted by the gateway for the third time, should be 15000-3 × 2 ═ 14994 milliseconds; by analogy, when the gateway transmits the description information of the package to be upgraded once, the corresponding countdown in the description information is reduced by 2 milliseconds.

For the L electronic tags, in order to keep low power consumption, the electronic tags cannot be in a receiving state for a long time, and it is usually set that 1.5 milliseconds are in the receiving state every 1 second, but it cannot be guaranteed that the L electronic tags can be in the receiving state at the same time, that is, it cannot be guaranteed that the L electronic tags can receive the target upgrade package at the same time, so the L electronic tags can receive the target upgrade package by using the counting method of the countdown. For example, if the electronic tag a listens to the description information when the gateway transmits the description information of the packet to be upgraded for the first time, the electronic tag a may prepare to receive the data of the first sub-packet in 14998 milliseconds after the electronic tag a listens to the description information; assuming that the electronic tag B listens to the description information when the gateway transmits the description information of the packet to be upgraded for the third time, the electronic tag may prepare to receive the data of the first sub-packet 14994 milliseconds after the electronic tag listens to the description information; therefore, the electronic tags a and B start to receive the data of the first sub-packet at the same time, and so on, all L electronic tags can ensure that the data of the first sub-packet starts to be received at the same time.

It should be understood that if the target upgrade package is the to-be-upgraded package, the counting method of the countdown corresponding to the transmission frequency to which the description information belongs is the same as that when the target upgrade package is the first sub-package, that is, if the target upgrade package is the to-be-upgraded package, the counting method of the countdown corresponding to the transmission frequency to which the description information belongs is adopted, and it can also be ensured that all the L electronic tags can start to receive the data of the to-be-upgraded package at the same time.

In a possible implementation manner, when the target upgrade packet is the first sub-packet, the target upgrade packet further includes a transmission time and a transmission repetition number of a next sub-packet of the target upgrade packet, and before performing firmware upgrade based on the target upgrade packet, the method further includes:

when the gateway reaches the transmitting time of the next sub-packet, transmitting a target upgrading packet to the electronic tag based on the transmitting repetition times of the next sub-packet;

the electronic tag determines that the upgrading packet data in the target upgrading packet is the total upgrading packet data, receives a next sub-packet when the countdown in the target upgrading packet is finished, adds the upgrading packet data in the next sub-packet to the total upgrading packet data, and determines that the next sub-packet is the target upgrading packet; judging whether the target upgrading packet contains countdown or not, if the target upgrading packet contains countdown, returning to the step of receiving the next sub-packet when the countdown of the electronic tag in the target upgrading packet is finished and the subsequent steps until the target upgrading packet does not contain countdown;

and upgrading the firmware based on the target upgrade package, wherein the upgrading process comprises the following steps:

and updating the firmware based on the total updating packet data.

In this embodiment of the present application, the number of times of repeatedly transmitting the next sub-packet may be set according to the number of devices of the electronic tag to be upgraded, that is, the number of devices of the electronic tag to be upgraded is larger, and the number of times of repeatedly transmitting the next sub-packet is larger.

Illustratively, the electronic tag firstly determines the upgrade packet data in a first sub-packet as total upgrade packet data, transmits the first sub-packet according to the repeated transmission times of a target upgrade packet (in this case, the first sub-packet), calculates countdown corresponding to the repeated transmission times of a second sub-packet in the first sub-packet according to the repeated transmission times of the second sub-packet, receives the second sub-packet when the countdown in the first sub-packet is over, adds the upgrade packet data in the second sub-packet to the total upgrade packet, determines that the second sub-packet is the target upgrade packet, judges whether the second sub-packet comprises the countdown of the third sub-packet, if the second sub-packet comprises the countdown of the third sub-packet, continues to receive the third sub-packet after the countdown in the second sub-packet is over, adds the upgrade packet data in the third sub-packet to the total upgrade packet, determines that the third sub-packet is the target upgrade packet, and sequentially judges each target upgrade packet, and when the target upgrade package does not contain the countdown, finishing receiving, determining the total upgrade package data, and upgrading the firmware based on the total upgrade package data.

In a possible implementation manner, the description information of the package to be upgraded further includes a transmission frequency point of the target upgrade package; the firmware upgrading method further comprises the following steps:

the gateway transmits the target upgrading packet to the electronic tag at the transmitting frequency point of the target upgrading packet;

under the condition that the electronic tag monitors the description information, the electronic tag receives a target upgrade package when the countdown in the description information is finished, and the method comprises the following steps:

and under the condition that the electronic tag monitors the description information, skipping to a transmitting frequency point of the target upgrading packet to receive the target upgrading packet when the countdown of the description information is finished.

In the embodiment of the application, the transmitting frequency point in the description information enables the electronic tag to jump to a designated frequency point (namely the transmitting frequency point) to receive the target upgrade package under the condition that the electronic tag monitors the description information, so that the electronic tag can accurately receive the target upgrade package.

According to the method and the device, the electronic tags can receive the target upgrading packet at the appointed time according to countdown after monitoring the description information of the packet to be upgraded through countdown corresponding to the transmitting times of the description information configured by the gateway, and upgrading is carried out based on the target upgrading packet, so that batch upgrading of L electronic tags is realized, the time cost for upgrading the L electronic tags in sequence is reduced, and the upgrading efficiency of firmware upgrading is improved.

Referring to fig. 2, a flowchart of a firmware upgrading method provided in the second embodiment of the present application is shown, where the firmware upgrading method is applied to the firmware upgrading system shown in fig. 1. As shown in fig. 2, the firmware upgrade method may include the steps of:

step 201, when the total data volume of the upgrade package in the description information of the package to be upgraded is greater than the data volume transmitted by each package, the gateway calculates the total package number corresponding to the package to be upgraded based on the total data volume of the upgrade package and the data volume transmitted by each package; and dividing the packet to be upgraded into N sub-packets, and determining the first sub-packet as a target upgrade packet.

In this embodiment of the application, in order to reduce the data transmission burden of the system, a certain upper limit needs to be set on the data amount during data transmission between the gateway and the electronic tag, for example, the data amount transmitted each time cannot exceed 100 bytes, at this time, if the total data amount of the upgrade package in the description information of the package to be upgraded is 500000 bytes, and transmission cannot be completed at one time, the total packet number corresponding to the package to be upgraded needs to be calculated according to the total data amount of the upgrade package and the data amount transmitted each package, that is, the total packet number is 500000/100 ═ 5000 packages, according to the total packet number corresponding to the package to be upgraded, the package to be upgraded is divided into 5000 sub-packets, and the sub-packet in the first transmission order among the 5000 sub-packets is determined as the target upgrade package.

Step 202, when the total data volume of the upgrade package is less than or equal to the data volume transmitted by each package, the gateway determines that the package to be upgraded is the target upgrade package.

In the embodiment of the application, if the total data volume of the upgrade package is less than or equal to the data volume transmitted by each package, subpackaging is not needed, the package to be upgraded can be directly determined as the target upgrade package, and the method can be applied to application scenes with less transmission data volume, such as batch updating of pictures or batch configuration of electronic tags.

Step 203, the gateway transmits the description information of the package to be upgraded for M times to the electronic tag, and transmits the target upgrade package to the electronic tag based on the transmission repetition times of the target upgrade package in the description information when the transmission time of the target upgrade package is reached.

In this embodiment of the application, M is an integer greater than zero, and as shown in fig. 3, it is a data transmission timing diagram of interaction between the gateway and the electronic tag, where the number of times that the gateway first transmits the description information of the package to be upgraded to the electronic tag is M times, so as to ensure that each electronic tag can monitor the description information. At this time, the transmission repetition times in the description information is M times, and when the transmission time of the target upgrade package is reached, the times that the gateway transmits the target upgrade package to the electronic tag is also M times.

And 204, under the condition that the electronic tag monitors the description information, receiving the target upgrade package when the countdown in the description information is finished, and upgrading the firmware based on the target upgrade package.

In this embodiment of the application, the electronic tag may monitor the description information transmitted by the gateway by setting the network interface to a monitoring mode, and specifically, may monitor the description information of the packet to be upgraded wirelessly or by using a private 2.4G protocol.

In the embodiment of the application, firstly, when the total data volume of an upgrading packet in the description information of the packet to be upgraded is greater than the data volume transmitted by each packet, a gateway divides the packet to be upgraded into N sub-packets, and determines a first sub-packet as a target upgrading packet; when the total data volume of the upgrade package is less than or equal to the data volume transmitted by each package, determining the package to be upgraded as a target upgrade package; secondly, when the gateway reaches the transmitting time of the target upgrading packet, transmitting the target upgrading packet to the electronic tag based on the transmitting repetition times of the target upgrading packet in the description information; and finally, under the condition that the electronic tag monitors the description information, receiving a target upgrading packet when countdown in the description information is finished, and upgrading the firmware based on the target upgrading packet, wherein the countdown in the description information is the difference between the transmission time of the target upgrading packet and the first transmission time, and the first transmission time is the product of the data transmission time between the gateway and the electronic tag and the transmission times of the description information. Under the setting of the countdown, the at least one electronic tag can simultaneously receive the target upgrading packet sent by the gateway and simultaneously upgrade based on the target upgrading packet, so that batch upgrading of the at least one electronic tag can be realized, time cost of firmware upgrading is reduced, and upgrading efficiency of firmware upgrading is improved.

Referring to fig. 5, a flowchart of a firmware upgrading method provided by the fourth embodiment of the present application is shown, where the firmware upgrading method is applied to an electronic tag in the firmware upgrading system shown in fig. 1. As shown in fig. 4, the firmware upgrade method may include the steps of:

step 501, under the condition that the description information of the package to be upgraded transmitted by the gateway is monitored, receiving the target upgrade package when the countdown in the description information is finished.

In this embodiment of the application, when the total data volume of the upgrade package is less than or equal to the data volume transmitted by each package, the target upgrade package is the package to be upgraded, and the package to be upgraded is received when the countdown in the description information is finished, where the countdown in the description information is a difference between the transmission time of the package to be upgraded and the first transmission time, and the first transmission time is a product of the data transmission time between the gateway and the electronic tag and the transmission times of the description information. That is, if the description information of the package to be upgraded monitored by the electronic tag is the description information sent by the gateway at the 5 th time, the countdown for receiving the package to be upgraded corresponding to the description information sent at the 5 th time can be obtained in the description information, and the electronic tag is ready to receive the package to be upgraded before the countdown is finished, so that the package to be upgraded is received when the countdown is finished.

In this embodiment of the present application, when the total data amount of an upgrade package in description information is greater than the data amount transmitted by each package, a target upgrade package refers to a first sub-package obtained by dividing a package to be upgraded into N sub-packages, and receives the first sub-package when countdown in the description information is finished, where the countdown in the description information is a difference between transmission time of the first sub-package and first transmission time consumption, and the first transmission time consumption is a product of data transmission time between a gateway and an electronic tag and the number of transmission times to which the description information belongs. That is, if the description information of the first sub-packet monitored by the electronic tag is the description information sent by the gateway for the 5 th time, the countdown for receiving the first sub-packet corresponding to the description information sent for the 5 th time can be obtained in the description information, and the electronic tag should prepare for receiving the first sub-packet before the countdown is finished, so as to receive the first sub-packet when the countdown is finished.

In a possible implementation, the description information further includes a target firmware version and a target device number, and in a case that the description information of the packet to be upgraded transmitted by the gateway is monitored, the receiving of the target upgrade packet at the end of the countdown in the description information includes:

and under the condition of monitoring the description information, if the target equipment number is the same as the equipment number of the electronic tag and the target firmware version is different from the firmware version of the electronic tag, receiving the target upgrade package when the countdown in the description information is finished.

The target device number may be divided into a target major number and a target subclass number, the device number of the electronic tag may be divided into a major number and a subclass number, and the target device number may be determined to be the same as the device number of the electronic tag if the target major number is the same as the device number of the electronic tag and the target subclass number is the same as the subclass number of the electronic tag.

In the embodiment of the application, the target firmware version is different from the firmware version of the electronic tag, which means that the current firmware version of the electronic tag is different from the firmware version to be upgraded, and therefore the electronic tag needs to be upgraded.

And 502, upgrading the firmware based on the target upgrading package.

In the embodiment of the application, the firmware upgrade based on the target upgrade package may firstly determine the total upgrade package data in the target upgrade package, and secondly perform the firmware upgrade based on the total upgrade package data.

If the target upgrade package is the package to be upgraded, the total upgrade package data in the target upgrade package can be the upgrade package data in the package to be upgraded; if the target upgrade package is the first sub-package, the total upgrade package data in the target upgrade package may refer to the sum of the upgrade package data in the N sub-packages.

In one possible implementation, before the firmware upgrade is performed based on the target upgrade package, the firmware upgrade method further includes:

and checking the target upgrade packet data, if the checking result is that the target upgrade packet is a correct upgrade packet, upgrading the firmware based on the target upgrade packet, and if the checking result is that the target upgrade packet is an incorrect upgrade packet, reporting the result of upgrade failure and uploading an error code.

In the embodiment of the present application, the description information further includes a first version protocol, first signature data, and a first current packet data volume; the target upgrading package also comprises a second version protocol, second signature data, a second current package data volume and upgrading package data;

when the target upgrade package is a package to be upgraded, the data volume of the first current package in the description information is the data volume of the package to be upgraded, and when the target upgrade package is a first sub-package, the data volume of the first current package in the description information is the data volume of the first sub-package allocated by the gateway. The second current packet data amount refers to the data amount of the transmitted packet in the process of data transmission between the gateway and the electronic tag, and is determined by the gateway allocation.

The first version protocol, the first signature data and the first current packet data volume may be encapsulated in header information of the description information, and the second version protocol, the second signature data and the second current packet data volume may be encapsulated in header information of the target upgrade packet.

Verifying the target upgrade package data may specifically include:

under the condition that the description information is monitored, if the first version protocol is the same as the version protocol of the electronic tag and the first signature data is the same as the signature data of the electronic tag, determining that the description information is legal;

if the second version protocol is the same as the version protocol of the electronic tag, the second signature data is the same as the signature data of the electronic tag, and the second current packet data volume is the same as the data volume of the upgrade packet data in the target upgrade packet, determining that the target upgrade packet is legal;

if the index number of the target upgrading packet is N when the receiving is finished, determining that the first verification result of the target upgrading packet is correct;

if the second current packet data volume is the same as the data volume of the upgrade packet data in the target upgrade packet, determining that the second check result of the target upgrade packet is correct;

if the index number of the target upgrade package meets the preset index number increasing requirement, determining that the third verification result of the target upgrade package is correct;

if the data volume of the total upgrade package data is the same as the total data volume of the upgrade packages in the description information, determining that the fourth verification result of the target upgrade package is correct, wherein the total upgrade package data comprises all the received upgrade package data of the target upgrade package;

when the target upgrading packet is the packet to be upgraded, if the second check result and the fourth check result are both correct, the description information is legal, and the target upgrading packet is legal, determining that the target upgrading packet is the correct upgrading packet;

when the target upgrade package is a first sub-package, if the first check result, the second check result, the third check result and the fourth check result are all correct, the description information is legal, and the target upgrade package is legal, determining that the target upgrade package is a correct upgrade package;

in this embodiment of the application, when the third verification result is determined, an increment requirement for the index number may be preset in the gateway, and then it is determined whether the index number of the target upgrade package meets the preset increment requirement for the index number, for example, if the increment requirement for the index number in the gateway is 1, it is determined whether the index number of the target upgrade package meets the preset increment requirement for the index number by comparing whether the index number of the adjacent target upgrade package is incremented by 1.

It should be understood that when the target upgrade package is a package to be upgraded, if any one of the second check result and the fourth check result is incorrect or the description information is illegal or the target upgrade package is illegal, the target upgrade package is determined to be an erroneous upgrade package; and when the target upgrading packet is the first sub-packet, if any one of the first check result, the second check result, the third check result and the fourth check result is incorrect or the description information is illegal or the target upgrading packet is illegal, determining that the target upgrading packet is an error upgrading packet.

determining the reporting time of the firmware upgrading result based on the reporting time interval;

and reporting the firmware upgrading result according to the reporting time, and returning to execute the step of generating the random time and the subsequent steps until the number of reporting the firmware upgrading result is equal to the preset number.

Illustratively, if the number of the devices of the electronic tag to be upgraded is 1000, and the time required for reporting the firmware upgrade result of the electronic tag is 1 millisecond, the reporting time interval is 1000 × 1+ rand (1-1000), the rand (1-1000) is a random number selected from 1 to 1000, the time for finishing upgrading is determined according to the reporting time interval and the electronic tag, the reporting time of the firmware upgrade result is determined, after the firmware upgrade result is reported for the first time according to the reporting time, the time interval is calculated again according to the method for calculating the time interval, after the time interval passes, the firmware upgrade result is reported again until the number of times for reporting the firmware upgrade result is equal to the preset number of times. Since at least one electronic tag is easy to collide when reporting the firmware upgrade result at the same time, a method of reporting for multiple times based on the reporting time interval can be selected to ensure that each electronic tag can report the firmware upgrade result successfully.

In the embodiment of the application, when the electronic tag monitors the description information, the electronic tag receives the target upgrade package when countdown in the description information is finished, and performs firmware upgrade based on the target upgrade package, where the countdown in the description information is a difference between transmission time of the target upgrade package and first transmission time, and the first transmission time is a product of data transmission time between the gateway and the electronic tag and transmission times of the description information. Under the setting of the countdown, the at least one electronic tag can simultaneously receive the target upgrading packet sent by the gateway and simultaneously upgrade based on the target upgrading packet, so that batch upgrading of the at least one electronic tag can be realized, time cost of firmware upgrading is reduced, and upgrading efficiency of firmware upgrading is improved.
