Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments given herein by one of ordinary skill in the art, are within the scope of the invention.
First, terms of art that may be used in the embodiments of the present application are explained:
a gateway: the intelligent household equipment is connected with a cloud platform, is added with sub-equipment, and supports protocol analysis and edge calculation;
the sub-equipment: an intelligent home device such as a switch, a socket and the like which must be connected with a cloud platform through a gateway;
communication group: the gateways in the group can communicate with each other;
a main gateway: selecting the gateway in the group according to the capability of the gateway equipment;
authenticating the gateway: gateways other than the main gateway in the group;
linkage: the user configures linkage rules on an APP (application, mobile phone software), and the sub-device 1 triggers the event linkage sub-device 2 to execute actions, such as unlocking a linkage lock and turning on a light.
In a first aspect of the embodiments of the present application, a communication system based on dynamic gateways is provided first, and referring to fig. 1, the communication system includes a cloud platform 101 and a plurality of gateways, where the cloud platform is connected to each gateway, and each gateway is connected to at least one other gateway;
the cloud platform 101 is used for receiving a control instruction aiming at the target equipment sent by the client; determining a gateway directly connected with the target equipment according to the control instruction to obtain a target gateway; forwarding the control instruction to a destination gateway; when the control instruction is failed to be forwarded to the target gateway, selecting a gateway with the optimal preset capability index from all gateways except the target gateway to obtain a designated gateway; forwarding the control instruction to a designated gateway;
the designated gateway 102 is used for forwarding the control instruction to the destination gateway;
and the destination gateway 103 is used for forwarding the control instruction to the target device.
The cloud platform in the embodiment of the application may be a back-end device that receives a control instruction for a target device sent by a user, and the cloud platform may forward the received control instruction to a destination gateway directly connected to the target device. For example, when the method of the embodiment of the application is applied to an intelligent home device, a user sends a control instruction for a certain intelligent home device through a control APP of an intelligent home system, sends the control instruction to a cloud platform at a rear end, forwards the control instruction to a destination gateway directly connected to the intelligent home device to be controlled through the cloud platform, and finally sends the control instruction to the intelligent home device to be controlled through the destination gateway to control the intelligent home device. For example, referring to fig. 2, the smart home system is composed of an APP, a cloud platform, a gateway and a sub-device, the sub-device is added to the gateway, the gateway is connected to the cloud platform through a home router, the APP controls the home gateway and the sub-device through the cloud platform, when a user needs to control the sub-device 3, the control instruction is sent to the cloud platform through the APP, the cloud platform sends the control instruction to a gateway B in a communication group through the router, and finally the gateway B sends the control instruction to the sub-device 3 to control the sub-device.
The control information sent by the client and received by the cloud platform can include identification information of the target device, meanwhile, direct-connected target gateways corresponding to different devices can be stored in the cloud platform in advance, when the corresponding target device is identified according to the identification information stored in the control information, the target gateway directly connected with the target device can be identified according to the direct-connected target gateway corresponding to the different devices stored in the cloud platform, and then the control instruction is sent to the target gateway.
In the actual use process, due to the fact that the load of the gateway exceeds the processing capacity of the gateway, communication faults and the like, the cloud platform fails to forward the control instruction to the target gateway. The preset capability index in the embodiment of the present application may be an index representing the capability of the gateway to process information currently. Specifically, the gateway capability value, load, operation duration, and gateway type may be included, but are not limited to.
In the embodiment of the application, a communication connection exists between the designated gateway and the destination gateway. In the actual use process, each gateway in the system can be marked as a communication group, and the gateways in the communication group can communicate with each other. The designated gateway can receive and forward the control instruction to the destination gateway, and forward the control instruction to the target device through the destination gateway, thereby realizing the control of the target device. For example, referring to fig. 3, when a user sends a control instruction for a child device to a cloud platform through an APP and the cloud platform is required to forward the control instruction to a gateway C directly connected to the child device, when a communication fault occurs between the cloud platform and the gateway C, the control instruction may be forwarded to the gateway a, the control instruction is forwarded to the gateway C by the main gateway, and finally the control instruction is forwarded to the child device by the gateway C, so as to implement control over the child device.
Therefore, by the system provided by the embodiment of the application, when the cloud platform fails to forward the control instruction to the target gateway, the gateway with the optimal preset capability index is selected from the gateways except the target gateway to obtain the designated gateway, and the control instruction is forwarded through the designated gateway, so that the problem that a user cannot control the target equipment when the cloud platform fails to forward the control instruction to the gateway directly connected with the target equipment is solved, and the stability and the availability of the system are improved.
Optionally, when the cloud platform selects a gateway with the optimal preset capability index from the gateways except the destination gateway, the preset capability index may be calculated according to a plurality of indexes. Specifically, the cloud platform is specifically configured to obtain gateway capability values, current loads, operation durations, and gateway types of the gateways except the destination gateway when forwarding the control instruction to the destination gateway fails; calculating to obtain a preset capacity index through a preset weight according to the gateway capacity value, the load, the running time and the gateway type of each gateway; and selecting the gateway with the optimal preset capacity index to obtain the designated gateway.
In the embodiment of the present application, the gateway capability value may be an index used for characterizing the processing capability of the gateway, for example, the gateway capability value may be a bandwidth, an upper limit of a load, and the like. The load is an index for characterizing the current information processing amount of the gateway. The running duration may represent a duration from the current startup to the current time, and/or a duration from the initial startup to the current time. The gateway type may be a version of the gateway, a type of information that can be processed, and the like. The preset capability index is obtained through preset weight calculation according to the gateway capability value, the load, the operation time and the gateway type of each gateway, different weights can be set in advance according to the gateway capability value, the load, the operation time and the gateway type, and during calculation, weighted summation can be carried out to obtain the corresponding preset capability index. For some indexes, for example, versions, because they cannot be represented by numerical values, different numerical values may be set for different types, for example, different versions, and in the calculation process, calculation may be performed by corresponding numerical values. When the gateway with the optimal preset capability index is selected to obtain the designated gateway, the calculated preset capability indexes of the gateways can be sequenced, and then the gateway with the optimal preset capability index is selected according to the sequencing result to obtain the designated gateway.
Therefore, the system of the embodiment of the application can obtain the gateway capacity value, the current load, the running time and the gateway type of each gateway except the target gateway; and selecting the gateway with the optimal preset capacity index according to the gateway capacity value, load, running time and gateway type of each gateway and the preset capacity index obtained by preset weight calculation to obtain the appointed gateway, so that control information is forwarded through the appointed gateway, the control information is forwarded to the target gateway, and the control of the target equipment is realized.
Optionally, each gateway is configured to calculate a first preset duration at each interval and send a gateway capability value of each gateway to the other gateways; comparing the gateway capacity value with the received gateway capacity value, if the gateway capacity value is larger than the received gateway capacity value, feeding back the gateway capacity value, and if the gateway capacity value is smaller than the received gateway capacity value, not feeding back the gateway capacity value;
the main gateway is used for determining the gateway as the main gateway when the own gateway capability value is larger than all the received gateway capability values;
the cloud platform is specifically configured to forward the control instruction to the primary gateway when forwarding the control instruction to the destination gateway fails, so that the primary gateway forwards the control instruction to the destination gateway.
The gateway sends the self capacity value to other gateways, compares the self capacity value with the received capacity value, sends feedback information to the other side when the self capacity value is larger than the received capacity value, and does not send the feedback information when the self capacity value is smaller than the received capacity value, so that the sending amount of the information can be reduced, and the selection speed of the gateway with the maximum gateway capacity value, namely the main gateway, is improved. Wherein the gateway capability value of the main gateway should be greater than all the remaining gateways. In the actual use process, the capability value can be sent in the form of a message, if the capability value of the gateway is larger than the received capability value of the gateway, the capability value of the gateway can be sent to the opposite side, and if the capability value of the gateway is smaller than the received capability value, the message can be discarded. The preset duration can be set according to actual conditions.
If the capability value of a certain gateway is larger than the received capability values of all gateways, the gateway can be determined as the main gateway. In the actual use process, a time threshold value can be set, and if the self capacity value is sent to the opposite side and exceeds the preset time threshold value and no information fed back by the opposite side is received, the self capacity value can be determined to be larger than the capacity value of the opposite side.
For example, referring to fig. 4, the gateway periodically sends a capability value notification message to the local area network, and after receiving the capability value notification message, other gateways compare the capability value with the capability value. And if the self-ability value is larger than the opposite-party ability value, sending a self-ability value notification message to the local area network. And if the value is less than the opposite party capacity value, discarding the message. The gateway sends the notification message, the notification message with the capacity value larger than that of the gateway is not received within 15 seconds, a communication group is created, the gateway is selected as a main gateway of the communication group, and the main gateway notification message is sent to the local area network. And other gateways in the local area network join the communication group after receiving the main gateway notification message to form a communication group authentication gateway. And reporting the information of the communication group members to the cloud platform.
And the main gateway is also used for creating a communication group and notifying the main gateway information and the communication group information to other gateways so as to enable the other gateways to join the communication group.
Specifically, after determining that a gateway is a master gateway, a gateway may send a master gateway advertisement message to each of the other gateways, and after receiving the message, each gateway may determine information of the master gateway according to the message, specifically, the information may include an address, a performance, and the like of the master gateway. The notification message may further include communication group information created by the main gateway, and after receiving the notification message, other gateways may join the communication group according to the communication group information in the message. After some gateways join the communication group, the main gateway may report all group member information to the cloud platform, which may be specifically referred to in the following embodiments. The communication group is established through the main gateway, and each gateway is added into the established communication group, so that the same management of the gateways in the communication group can be carried out through the communication group, and the information sending or management efficiency is improved.
The main gateway is a gateway which is calculated by every first preset time interval of each gateway and is compared and selected after the gateway capacity value of the main gateway is sent to other gateways, and therefore dynamic updating of the main gateway can be achieved. And the communication group is established after the main gateway is determined, so that the dynamic update of the communication group can be realized, and the update and the management of the communication group through the gateway with the strongest gateway capability are realized.
Optionally, the master gateway is configured to send a gateway information obtaining instruction to each gateway in the communication group every second preset time interval; receiving gateway information fed back by each gateway and integrating the gateway information to obtain integrated routing information; feeding back integrated routing information to each gateway in the communication group so that each gateway receives and stores the integrated routing information;
the cloud platform is also used for acquiring the integrated routing information when the control instruction is failed to be forwarded to the destination gateway; calculating and selecting a gateway with the optimal preset capacity index according to the integrated routing information to obtain a designated gateway; the control instructions are forwarded to the designated gateway.
The main gateway is used for sending a gateway information acquisition instruction to each gateway in the communication group, and can be an instruction for acquiring information such as gateway capability values, loads, operation durations, gateway types, gateway network information, gateway service capabilities, sub-device information and the like of each gateway. Then the main gateway integrates the received gateway capability value, load, running time, gateway type, gateway network information, gateway service capability and sub-equipment information to obtain integrated routing information, specifically, the received gateway capability value, load, running time, gateway type, gateway network information, gateway service capability and sub-equipment information of each gateway are integrated, the gateway capability values, load, operation duration, gateway types, gateway network information, gateway service capabilities, and sub-device information of each gateway may be classified and packaged, for example, in units of gateways to obtain integrated routing information, the integrated routing information may include a gateway capability value, a load, an operation duration, a gateway type, gateway network information, a gateway service capability, and sub-device information of the main gateway itself. After the integration, the master gateway may send the integrated routing information to each gateway. Each gateway may store the consolidated routing information after receiving it. In an actual use process, the second preset time length at each interval may be equal to or greater than the first preset time length, a gateway information acquisition instruction is sent to each gateway in the communication group through the second preset time length at each interval to generate integrated routing information, and the integrated routing information is fed back to each gateway in the communication group, so that each gateway can update the stored integrated routing information after receiving the integrated routing information, thereby implementing dynamic update of the integrated routing information.
