Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The intelligent equipment upgrading method provided by the embodiment of the application can be applied to an application environment shown in fig. 1.
It will be appreciated that the control terminal communicates with the smart devices via a communication network, for example via wireless communication technology (WiFi), and is responsible for device upgrades to the smart devices to be upgraded in the smart devices.
The data storage system can store data which the control terminal needs to process, and can be integrated on the control terminal or placed on a cloud service or other network servers. If the data storage system is placed on the cloud service and the data storage system receives the firmware upgrading data of the latest version, the data storage system informs the control terminal to enable the control terminal to download the firmware upgrading data of the latest version, enable the control terminal to select intelligent equipment to be upgraded, which needs to be subjected to firmware upgrading, from all intelligent equipment, and then carry out equipment upgrading on the intelligent equipment to be upgraded, which needs to be subjected to firmware upgrading, according to the firmware upgrading data of the latest version.
The control terminal can be understood as intelligent central control, and can be at least one of a personal computer, a notebook computer, a smart phone, a tablet computer, an internet of things device, a portable wearable device, a control terminal, a server, a movable control panel or a control knob and the like for installing specific program software. The internet of things equipment can be an intelligent sound box, an intelligent television, an intelligent air conditioner, intelligent vehicle-mounted equipment and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The intelligent device can be, but is not limited to, at least one intelligent home device of an intelligent lamp, an intelligent control panel, an intelligent sound box, an intelligent television or an intelligent air conditioner and the like.
In some embodiments, as shown in fig. 2, an intelligent device upgrading method is provided, and an embodiment of the present application is illustrated by using the method applied to the control terminal shown in fig. 1 as an example, including, but not limited to, the following steps:
Step 202, determining an intelligent device to be upgraded corresponding to the firmware upgrade data.
The firmware refers to an intelligent device 'driver' stored in the intelligent device, and through the firmware, an operating system can realize the running action of a specific machine according to a standard device driver.
Firmware upgrade data refers to related data for upgrading firmware of the smart device.
The intelligent equipment to be upgraded refers to controlled equipment which is to be upgraded and can be controlled by the control terminal. It is understood that the control terminal may determine whether the corresponding smart device is a device to be upgraded by looking at the firmware version of each smart device.
In some embodiments, after acquiring the latest firmware upgrade data, the control terminal may determine the latest firmware version according to firmware version information of the firmware upgrade data. And then, the control terminal compares the firmware version with the current firmware version of each intelligent device. If the firmware version received by the control terminal is higher than the current firmware version of the intelligent device, the current firmware version of the intelligent device is not the latest version, and the intelligent device can be determined to be the device to be upgraded. If the firmware version received by the control terminal is not higher than the current firmware version of the intelligent device, the current firmware version of the intelligent device is the latest version, and the control terminal does not need to upgrade the intelligent device. By comparing the firmware versions of the intelligent devices, the application can effectively avoid repeated updating of the intelligent devices which do not need firmware updating, thereby saving the time for updating the devices.
Specifically, the control terminal determines the intelligent device to be upgraded corresponding to the firmware upgrade data from the intelligent devices.
Step 204, determining a target packet loss rate of the intelligent device to be upgraded.
The target packet loss rate is obtained by carrying out packet loss test on the intelligent equipment to be upgraded by the control terminal and is used for representing the packet loss condition of the intelligent equipment to be upgraded.
The packet loss test refers to a test for calculating the packet loss condition of the intelligent device by sending a data packet to the intelligent device to be upgraded.
Packet Loss (Packet Loss) refers to the failure of data of one or more packets (Packet) to reach a specified destination during transmission.
Packet loss rate refers to the ratio of the number of packets lost in transmission to the number of packets transmitted.
Specifically, the control terminal determines the target packet loss rate of the equipment to be upgraded by carrying out packet loss test on each intelligent equipment to be upgraded.
And 206, determining a redundant data packet for repairing the firmware upgrade data according to the target packet loss rate.
Specifically, the control terminal determines a redundant data packet for repairing firmware upgrade data according to the target packet loss rate. The purpose of determining the redundant data packet is that under the condition that the intelligent device to be upgraded cannot receive complete firmware upgrading data, the intelligent device to be upgraded can repair the incomplete firmware upgrading data directly according to the redundant data packet so as to repair the incomplete firmware upgrading data into the complete firmware upgrading data, and the intelligent device to be upgraded can be guaranteed to upgrade the device according to the complete firmware upgrading data in time.
And step 208, transmitting the firmware upgrading data and the redundant data packet to the intelligent equipment to be upgraded so that the intelligent equipment to be upgraded performs equipment upgrading according to the firmware upgrading data.
The redundant data packet is used for repairing the received firmware upgrading data under the condition that the firmware upgrading data received by the intelligent equipment to be upgraded are incomplete.
Specifically, the control terminal sends the firmware upgrading data and the redundant data packet I to the intelligent equipment to be upgraded, so that the intelligent equipment to be upgraded can directly upgrade the equipment according to the complete firmware upgrading data under the condition that the intelligent equipment to be upgraded receives the complete firmware upgrading data. In addition, under the condition that the intelligent equipment to be upgraded cannot receive complete firmware upgrading data, incomplete firmware upgrading data can be repaired directly through the redundant data packet, and the incomplete firmware upgrading data is repaired into complete firmware upgrading data and then is upgraded, so that the number of packet loss retransmission is reduced, and the intelligent equipment upgrading efficiency is improved.
According to the intelligent device upgrading method, when the control terminal needs to upgrade the firmware of the intelligent device, the intelligent device to be upgraded corresponding to the firmware upgrading data needs to be determined, repeated upgrading of the intelligent device which does not need to be upgraded is effectively avoided, and the duration of firmware upgrading can be saved. And secondly, the control terminal performs packet loss test on each intelligent device to be upgraded to obtain a target packet loss rate, and determines a redundant data packet for repairing firmware upgrading data according to the target packet loss rate. And then, the control terminal sends the firmware upgrading data and the redundant data packet I to the intelligent equipment to be upgraded, if the firmware upgrading data received by the intelligent equipment to be upgraded is complete, the equipment to be upgraded can carry out equipment upgrading according to the firmware upgrading data, and if the firmware upgrading data received by the intelligent equipment to be upgraded is incomplete, the equipment to be upgraded can also directly recover the received firmware upgrading packet by itself through the received redundant data packet, so that the number of packet loss retransmission is reduced, and the intelligent equipment upgrading efficiency is improved.
In some embodiments, the smart device to be upgraded is a plurality of smart devices, and step 204 specifically includes, but is not limited to, including: sending a plurality of test packets for carrying out packet loss test to a plurality of intelligent devices to be upgraded; according to the number of the test packets sent to each intelligent device to be upgraded and the number of the test packets received by each intelligent device to be upgraded, calculating the packet loss rate of each intelligent device to be upgraded; and selecting a target packet loss rate from the packet loss rates of the intelligent devices to be upgraded.
The test packet refers to a data packet sent to each intelligent device to be upgraded when the control terminal performs packet loss test on each intelligent device to be upgraded.
Specifically, the control terminal sends a plurality of data packets for carrying out packet loss test to a plurality of intelligent devices to be upgraded as test packets. And then, the control terminal calculates the packet loss rate of each device to be upgraded according to the number of the test packets sent to each intelligent device to be upgraded by the control terminal and the number of the test packets actually received by each device to be upgraded. And finally, the control terminal selects one of the packet loss rates from the packet loss rates of the equipment to be upgraded as a target packet loss rate. According to the method and the device, the packet loss rate of each intelligent device to be upgraded is calculated, the overall packet loss condition of the intelligent device to be upgraded can be known in advance before the intelligent device to be upgraded is upgraded, and the redundant data packet is generated according to the target packet loss rate, so that firmware upgrading data is repaired through the redundant data packet, and the equipment upgrading efficiency is improved.
In some embodiments, if the intelligent device to be upgraded is an intelligent lamp, the intelligent lamp includes an intelligent lamp 1, an intelligent lamp 2, an intelligent lamp 3, an intelligent lamp 4 and an intelligent lamp 5, and the control terminal can pull the intelligent lamp 1, the intelligent lamp 2, the intelligent lamp 3, the intelligent lamp 4 and the intelligent lamp 5 to the same group, for example, the group 1, so as to perform a batch packet loss test on the intelligent lamps in the same group. Next, the control terminal continuously transmits N test packets at a certain rate for the intelligent lamp 1, the intelligent lamp 2, the intelligent lamp 3, the intelligent lamp 4, and the intelligent lamp 5 in the group 1 through the multicast technology (Multicast Technology). Because the intelligent lamp may lose packets under the condition of bad signals, the control terminal needs to respectively read the number M of the test packets actually received by the intelligent lamp 1, the intelligent lamp 2, the intelligent lamp 3, the intelligent lamp 4 and the intelligent lamp 5 in a unicast mode. And then, the control terminal obtains the packet loss rate K of each intelligent lamp according to the ratio of the number M of the test packets actually received by each intelligent lamp and the number N of the test packets sent to each intelligent lamp. After calculating the packet loss rate of each intelligent lamp, selecting one packet loss rate as a target packet loss rate.
Wherein multicast refers to a network communication in which a single sender corresponds to multiple receivers.
In some embodiments, the process of selecting the target packet loss rate from the plurality of packet loss rates may be selecting a maximum packet loss rate from the plurality of packet loss rates as the target packet loss rate. In some embodiments, the multiple packet loss rates may be further sorted from large to small or from small to large, and after sorting, the packet loss rates within a certain range are selected, and then the maximum packet loss rate is selected as the target packet loss rate.
In some embodiments, step 208 specifically includes, but is not limited to including: and sending the firmware upgrading data and the redundant data packet to a plurality of intelligent devices to be upgraded so as to enable the intelligent devices to be upgraded to carry out device upgrading.
Specifically, the control terminal sends firmware upgrading data and redundant data packets to a plurality of intelligent devices to be upgraded, so that the intelligent devices to be upgraded can be upgraded simultaneously. The control terminal can upgrade the equipment of a single intelligent equipment to be upgraded, and can upgrade a plurality of equipment to be upgraded in batches, so that the time spent for equipment upgrade can be effectively reduced.
In some embodiments, prior to step 206, the smart device upgrade method of the present application specifically further includes, but is not limited to, including: dividing the firmware upgrade data to obtain a plurality of upgrade package combinations.
Wherein, each upgrade package combination comprises at least one firmware upgrade package.
Specifically, the control terminal may further segment firmware upgrade data to obtain a plurality of upgrade package combinations.
It may be understood that the control terminal may divide the firmware upgrade data into a plurality of firmware upgrade packages, and combine a certain number of firmware upgrade packages to obtain an upgrade package combination. For example, if the size of the firmware upgrade data is 100KB, if the firmware upgrade data with the size of 100KB is divided into firmware upgrade packages according to a standard of 1KB, 100 firmware upgrade packages can be obtained, and if 10 firmware upgrade packages are combined into one upgrade package combination standard, 10 upgrade package combinations can be obtained.
Correspondingly, step 206 specifically includes, but is not limited to, including: and determining redundant data packets matched with each upgrading packet combination according to the target packet loss rate.
Specifically, the control terminal determines redundant data packets matched with each upgrade packet combination according to the calculated target packet loss rate.
Correspondingly, step 208 specifically further includes, but is not limited to, including: and sequentially taking each upgrade packet combination and the matched redundant data packet as the same transmission data group, and transmitting the transmission data group to the intelligent equipment to be upgraded.
Specifically, the control terminal sequentially combines each upgrade packet combination with the matched redundant data packet, that is, uses each upgrade packet combination and the matched redundant data packet as the same transmission data group, and transmits the corresponding transmission data group to each intelligent device to be upgraded respectively.
In some embodiments, the step of determining a redundant data packet matching each upgrade packet combination according to the target packet loss rate includes, but is not limited to, specifically including: aiming at each upgrade package combination, determining the number to be generated of redundant data packages matched with the upgrade package combination according to the number of upgrade firmware packages in the upgrade package combination and the target package loss rate; and performing code conversion on the upgrade firmware packages in the upgrade package combination based on the quantity to be generated, and generating redundant data packages which are matched with the upgrade package combination and accord with the quantity to be generated.
It will be appreciated that, according to the transmission characteristics of the wireless channel, packet loss of the upgrade firmware packet is generally random, so that the control terminal needs to use some coding algorithm, for example, a forward error correction coding technology, to generate a redundant data packet corresponding to the upgrade firmware packet before sending the upgrade firmware packet to the corresponding smart device to be upgraded.
In some embodiments, the number of redundant data packets to be generated is determined according to the target packet loss rate calculated in the above embodiments. For example, if the target packet loss rate R is 20%, it is conceivable to set 2 redundant data packets in an upgrade packet combination obtained by combining 10 firmware upgrade packets. In addition, it is considered that each upgrade firmware package in each upgrade package combination is numbered, and a redundant data package corresponding to each upgrade package combination is numbered, so as to identify each specific upgrade firmware package and redundant data package. After determining each upgrade package combination and the corresponding redundant data package, the upgrade package combination and the corresponding redundant data package can be sequentially sent to the intelligent device to be upgraded until all data sending is completed.
Specifically, the control terminal determines the number of redundant data packets to be generated, which are matched with the upgrade package combinations, according to the number of upgrade firmware packages and the target packet loss rate in the corresponding upgrade package combinations, for each upgrade package combination. And then, utilizing a forward error correction coding algorithm, and performing code conversion on the upgrade firmware packages in the upgrade package combination based on the quantity to be generated, so as to generate redundant data packages which are matched with the upgrade package combination and meet the quantity to be generated. It will be appreciated that if the number to be generated is 2, the number of redundant data packets generated by the error correction coding algorithm should also be 2.
In some embodiments, the sending data set is configured to trigger the intelligent device to be upgraded to determine a packet loss number of the sending data set in a process of transmitting to the intelligent device to be upgraded when the upgrade packet combination in the sending data set is not completely received by the intelligent device to be upgraded, and perform data repair on the incompletely received upgrade packet combination according to the received redundant data packet in the sending data set when the packet loss number is less than or equal to a number of redundant data packets in the sending data set.
The repaired upgrade package combination is used for upgrading the intelligent equipment to be upgraded.
The packet loss number refers to the number of lost upgrade firmware packets in the process of sending the upgrade packet combination by the control terminal.
Specifically, if the number of lost packets of the transmission data set in the process of transmitting the transmission data set to the intelligent device to be upgraded is smaller than or equal to the number of redundant data packets in the transmission data set, the intelligent device to be upgraded can repair the lost upgrade firmware packets through a coding algorithm for coding the redundant data packets so as to obtain a complete upgrade packet combination. After the intelligent equipment to be upgraded obtains the complete upgrade package combination, the intelligent equipment is upgraded according to the complete upgrade package combination.
In some embodiments, as shown in fig. 3, the transmission data set sent by the control terminal to the intelligent device to be upgraded includes 10 upgrade firmware packets, abbreviated as data packets, and also includes 2 redundant data packets, abbreviated as redundant packets. However, during the data transmission process, there may be a packet loss, which causes that the intelligent device to be upgraded cannot receive the complete data packet and the redundant packet, for example, the intelligent device to be upgraded cannot receive the data packet 4 and the redundant packet 1, and 2 packets of data are lost in total. Because the number of lost packets is not larger than the number of the set redundant data packets, a coding algorithm for coding the redundant data packets can be utilized, for example, a forward error correction coding algorithm is utilized for carrying out data recovery on the data packets 4, and after successful recovery, redundant packets 2 are removed, so that a complete upgrading firmware packet is obtained, and a control terminal can carry out equipment upgrading according to the complete upgrading firmware packet, so that the cost of packet loss retransmission is reduced, and the equipment upgrading efficiency is improved.
In some embodiments, if a sending data set does not lose any upgrade firmware packet during the data transmission process, the control terminal may directly remove the redundant data packet in the sending data set, and store the redundant data packet to the local for the device to be upgraded to upgrade the device.
In some embodiments, the smart device upgrade method of the present application specifically further includes, but is not limited to, including: under the condition that the number of the packet loss determined by the intelligent equipment to be upgraded is larger than the number of the redundant data packets in the transmission data set, determining a firmware upgrading packet to be supplemented according to the sequence number of the firmware upgrading packet in the transmission data set; and sending the firmware upgrade package to be supplemented to the intelligent equipment to be upgraded, so that the intelligent equipment to be upgraded performs equipment upgrade according to the firmware upgrade package in the received sending data set and the upgrade firmware package to be supplemented.
