Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The intelligent device upgrading method provided by the embodiment of the application can be applied to the application environment shown in fig. 1.
It can be understood that the control terminal communicates with the smart devices through a communication network, for example, through a wireless communication technology (WiFi), and is responsible for performing device upgrade on the smart devices to be upgraded in the smart devices.
The data storage system can store data to be processed by the control terminal, can be integrated on the control terminal, and can also be placed on a cloud service or other network servers. If the data storage system is placed on the cloud service and receives the firmware upgrading data of the latest version, the data storage system informs the control terminal so that the control terminal downloads the firmware upgrading data of the latest version, the control terminal selects the intelligent equipment to be upgraded, needing firmware upgrading, from the intelligent equipment, and then the intelligent equipment to be upgraded, needing firmware upgrading, is upgraded according to the firmware upgrading data of the latest version.
The control terminal can be understood as an 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, wherein the personal computer, the notebook computer, the smart phone, the tablet computer, the internet of things device, the portable wearable device, the control terminal, the server, the movable control panel or the control knob are provided with 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 can be a smart watch, a smart bracelet, a head-mounted device, and the like. The smart device may be, but is not limited to, at least one smart home device of a smart light fixture, a smart control panel, a smart sound box, a smart television, a smart air conditioner, or the like.
In some embodiments, as shown in fig. 2, an intelligent device upgrading method is provided, and the embodiments of the present application take an example in which the method is applied to the control terminal shown in fig. 1, including but not limited to the following steps:
The firmware refers to an intelligent device "driver" stored in the intelligent device, and through the firmware, the operating system can implement the operation action of a specific machine according to the standard device driver.
And the firmware upgrading data refers to relevant data for upgrading the firmware of the intelligent equipment.
The intelligent device to be upgraded refers to a controlled device to be upgraded and capable of being controlled by the control terminal. It can be understood that the control terminal may determine whether the corresponding intelligent device is a device to be upgraded by looking at the firmware version of each intelligent device.
In some embodiments, after acquiring the latest firmware upgrade data, the control terminal may determine the latest firmware version according to the 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 respectively. If the firmware version received by the control terminal is higher than the current firmware version of the intelligent device, it is indicated that the current firmware version of the intelligent device is not the latest version, and the intelligent device can be determined to be a 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, it indicates that the current firmware version of the intelligent device is the latest version, and at this time, the control terminal does not need to upgrade the intelligent device. According to the method and the device, the intelligent device which does not need firmware upgrading can be effectively prevented from being repeatedly upgraded by comparing the firmware versions of the intelligent devices, so that the time for upgrading the equipment is saved.
Specifically, the control terminal determines the intelligent device to be upgraded corresponding to the firmware upgrading data from each intelligent device.
And step 204, determining the target packet loss rate of the intelligent equipment to be upgraded.
The target packet loss rate is obtained by the control terminal performing packet loss test on the intelligent device to be upgraded and is used for representing the packet loss condition of the intelligent device to be upgraded.
And the packet loss test refers to a test for calculating the packet loss condition of the intelligent equipment by sending a data packet to the intelligent equipment to be upgraded.
Packet Loss (Packet Loss) means that data of one or more data packets (packets) cannot reach a designated destination in a transmission process.
The packet loss ratio refers to a ratio of the number of packets lost in transmission to the number of transmitted packets.
Specifically, the control terminal determines a target packet loss rate of the to-be-upgraded device by performing a packet loss test on each to-be-upgraded intelligent device.
And step 206, determining a redundant data packet for repairing the firmware upgrading data according to the target packet loss rate.
Specifically, the control terminal determines a redundant data packet for repairing the 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 directly repair incomplete firmware upgrading data according to the redundant data packet so as to repair the incomplete firmware upgrading data into complete firmware upgrading data, and the intelligent device to be upgraded can be guaranteed to be capable of performing device upgrading according to the complete firmware upgrading data in time.
And step 208, sending 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 device to be upgraded are incomplete.
Specifically, the control terminal sends the firmware upgrading data and the redundant data packet I to the intelligent device to be upgraded, so that the intelligent device to be upgraded can directly upgrade the equipment according to the complete firmware upgrading data under the condition that the complete firmware upgrading data is received by the intelligent device to be upgraded. In addition, under the condition that the intelligent equipment to be upgraded cannot receive complete firmware upgrading data, the incomplete firmware upgrading data can be directly repaired by self through the redundant data packet, and the complete firmware upgrading data is repaired and then the equipment is upgraded, so that the times of packet loss retransmission are reduced, and the upgrading efficiency of the intelligent equipment is improved.
According to the intelligent equipment upgrading method, when the control terminal needs to upgrade the firmware of the intelligent equipment, the intelligent equipment to be upgraded corresponding to the firmware upgrading data needs to be determined, so that the intelligent equipment which does not need to be upgraded is effectively prevented from being repeatedly upgraded, and the firmware upgrading time 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 the 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 are complete, the equipment to be upgraded can be upgraded according to the firmware upgrading data, and if the firmware upgrading data received by the intelligent equipment to be upgraded are incomplete, the equipment to be upgraded can also recover the received firmware upgrading packet directly through the received redundant data packet, so that the times of packet loss retransmission are reduced, and the efficiency of upgrading the intelligent equipment is improved.
In some embodiments, there are a plurality of smart devices to be upgraded, and step 204 specifically includes, but is not limited to, including: sending a plurality of test packets for packet loss test to a plurality of intelligent devices to be upgraded; calculating the packet loss rate of each intelligent device 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; 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 packet loss testing to the plurality of intelligent devices to be upgraded as test packets. And then, the control terminal calculates the packet loss rate of each to-be-upgraded device according to the number of the test packets sent to each to-be-upgraded intelligent device and the number of the test packets actually received by each to-be-upgraded device. And finally, the control terminal selects one of the packet loss rates from the packet loss rates of the devices 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 integral packet loss condition of each intelligent device to be upgraded can be known in advance before the intelligent device to be upgraded is upgraded, the redundant data packet is generated according to the target packet loss rate, the firmware upgrading data is repaired through the redundant data packet, and the device upgrading efficiency is improved.
In some embodiments, if the smart device to be upgraded is a smart lamp, where the smart lamp includes the smart lamp 1, the smart lamp 2, the smart lamp 3, the smart lamp 4, and the smart lamp 5, the control terminal may pull the smart lamp 1, the smart lamp 2, the smart lamp 3, the smart lamp 4, and the smart lamp 5 to a same group, for example, the group 1, so as to perform a batch packet loss test on the smart lamps in the same group. Next, the control terminal continuously transmits N test packets at a certain rate for the smart lamp 1, the smart lamp 2, the smart lamp 3, the smart lamp 4, and the smart lamp 5 in the group 1 through a Multicast Technology (Multicast Technology). Because the intelligent lamp may lose packets under the condition of poor signals, the control terminal needs to respectively read the number M of the test packets actually received by the intelligent lamps 1, 2, 3, 4 and 5 in a unicast manner. 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 to the number N of the test packets sent to each intelligent lamp. After the packet loss rates of the intelligent lamps are calculated, one packet loss rate is selected as a target packet loss rate.
The multicast technology refers to a network communication in which a single sender corresponds to a plurality of receivers.
In some embodiments, the 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 packet loss rates may be sorted from large to small or from small to large, and packet loss rates within a certain range are screened out after sorting, 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 that the plurality of intelligent devices to be upgraded are subjected to device upgrading.
Specifically, the control terminal sends the firmware upgrading data and the redundant data packet to the plurality of intelligent devices to be upgraded, so that the plurality of intelligent devices to be upgraded simultaneously perform device upgrading. The control terminal can upgrade equipment for a single intelligent device to be upgraded, can upgrade batched equipment for a plurality of devices to be upgraded simultaneously, and can effectively reduce the time spent on upgrading the equipment.
In some embodiments, before step 206, the method for upgrading an intelligent device of the present application further includes, but is not limited to: and segmenting the firmware upgrading data to obtain a plurality of upgrading packet combinations.
Wherein, each upgrade package combination comprises at least one firmware upgrade package.
Specifically, the control terminal may further segment the firmware upgrade data to obtain a plurality of upgrade package combinations.
It can 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 of 100KB size is divided into firmware upgrade packages according to the standard of 1KB, 100 firmware upgrade packages may be obtained, and if 10 firmware upgrade packages are combined into the standard of one upgrade package combination, 10 upgrade package combinations may be obtained.
Correspondingly, step 206 specifically includes, but is not limited to, including: and determining the redundant data packet matched with each upgrading packet combination according to the target packet loss rate.
Specifically, the control terminal determines the redundant data packet matched with each upgrade packet combination according to the calculated target packet loss rate.
Correspondingly, step 208 specifically includes, but is not limited to, including: and sequentially taking each upgrading packet combination and the matched redundant data packet as the same sending data group, and transmitting the sending data group to the intelligent equipment to be upgraded.
Specifically, the control terminal sequentially combines each upgrade package combination and the matched redundant data package, that is, each upgrade package combination and the matched redundant data package are used as the same transmission data group, and the corresponding transmission data groups are respectively transmitted to each intelligent device to be upgraded.
In some embodiments, the step of determining the redundant data packet matching with each upgrade packet combination according to the target packet loss ratio specifically includes, but is not limited to: for each upgrade package combination, determining the quantity to be generated of redundant data packages matched with the upgrade package combination according to the quantity of upgrade firmware packages in the upgrade package combination and the target packet 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 can be understood that, according to the transmission characteristics of the wireless channel, the packet loss of the upgrade firmware packet is generally random, so that the control terminal needs to use some coding algorithms, for example, a forward error correction coding technique, to generate a redundant data packet corresponding to the upgrade firmware packet before sending the upgrade firmware packet to the corresponding intelligent 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 according to the above embodiments. For example, if the target packet loss rate R is 20%, it may be considered that 2 redundant data packets are provided 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 each upgrade package combination and the corresponding redundant data package are determined, each upgrade package combination and the corresponding redundant data package can be sequentially sent to the intelligent device to be upgraded until all data are sent.
Specifically, the control terminal determines the to-be-generated number of the redundant data packets matched with the upgrade packet combination according to the number of upgrade firmware packets in the corresponding upgrade packet combination and the target packet loss rate for each upgrade packet combination. And then, coding conversion is carried out on the upgrade firmware packages in the upgrade package combination by utilizing a forward error correction coding algorithm and based on the quantity to be generated, and redundant data packages which are matched with the upgrade package combination and accord with the quantity to be generated are generated. It is understood that if the number to be generated is 2, the number of redundant data packets generated by the error correction coding algorithm should be 2.
In some embodiments, the sending data group is configured to, when the upgrade package combination in the sending data group is not completely received by the intelligent device to be upgraded, trigger the intelligent device to be upgraded to determine a packet loss number of the sending data group in a transmission process to the intelligent device to be upgraded, and when the packet loss number is less than or equal to the number of redundant data packages in the sending data group, perform data repair on the upgrade package combination that is not completely received according to the received redundant data packages in the sending data group.
And the repaired upgrading packet combination is used for upgrading the intelligent equipment to be upgraded.
And the number of lost packets refers to the number of the upgrade firmware packets lost in the process of sending the upgrade packet combination by the control terminal.
Specifically, if the number of lost packets of the sending data group in the process of transmitting to the intelligent device to be upgraded is less than or equal to the number of redundant data packets in the sending data group, the intelligent device to be upgraded may perform data restoration on the lost upgrade firmware packet through a coding algorithm for coding the redundant data packets, so as to obtain a complete upgrade packet combination. And after the intelligent equipment to be upgraded obtains the complete upgrade package combination, upgrading the equipment according to the complete upgrade package combination.
In some embodiments, as shown in fig. 3, the sending data set sent by the control terminal to the to-be-upgraded intelligent device includes 10 upgrade firmware packages, which are data packages for short, and also includes 2 redundant data packages, which are redundant packages for short. However, during the data transmission process, there may be a case of packet loss, which results in 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 packet data are lost in total. Because the number of lost packets is not greater than the number of the set redundant data packets, a coding algorithm for coding the redundant data packets, for example, a forward error correction coding algorithm, can be used for data recovery of the data packet 4, and after successful recovery, redundant packets 2 are removed, so that a complete upgrade firmware packet is obtained, the control terminal can perform equipment upgrade according to the complete upgrade firmware packet, the cost of packet loss retransmission is reduced, and the equipment upgrade efficiency is improved.
In some embodiments, if one sending data group does not lose any upgrade firmware packet in the data transmission process, the control terminal may directly remove the redundant data packet in the sending data group and store the redundant data packet to the local for the device to be upgraded to upgrade the device.
