Description
Technical Field
The invention relates to the technical field of intelligent home, in particular to an arbitration machine election method, an arbitration machine election device, intelligent equipment and a computer readable storage medium.
Background
In a distributed intelligent home system, a plurality of devices supporting intelligent wake-up are usually arranged in a local area network, when a wake-up signal is received, the problem that a plurality of intelligent devices respond to a user wake-up instruction at the same time possibly exists, the use experience of a user is affected, in the existing solution, an arbitration machine is selected at the end side, instruction interaction is carried out by the arbitration machine, and further, the fact that which device of the local area network can respond to wake-up is determined.
In the prior art, an arbitrator election is generally performed in a local area network broadcast negotiation mode, when a router disables local area network broadcast, the election method fails to affect the use experience of a user, in addition, when an arbitrator network selected through local area network broadcast is unstable, the situation that the arbitrator frequently goes on and off lines and is disconnected with other intelligent devices easily occurs, so that voice interaction of the user fails to affect the use experience of the user, and therefore, the arbitrator election method which can normally work under the condition that the router disables local area network broadcast and ensures stable connection between the selected arbitrator and other intelligent devices needs to be developed.
Disclosure of Invention
The invention solves the problems that when a router disables local area network broadcast, an arbitration machine election method in the prior art fails and the network connection state of an arbitration machine selected in the prior art is poor.
In order to solve the above problems, the present invention provides an arbitration machine election method, including: after the intelligent equipment is connected with the network and is accessed into the intelligent home system, an online message is sent through a multicast message, and an arbiter election is triggered; after receiving the online message, other intelligent devices in the intelligent home system send out own device information in a multicast message mode, and simultaneously test the connectivity of the own device to the new online intelligent device; the intelligent equipment which is newly online receives equipment information sent back by other intelligent equipment in the intelligent home system through a multicast message, and simultaneously tests the connectivity of the intelligent equipment and other intelligent equipment in the intelligent home system; the intelligent equipment in the intelligent home system votes for the arbiter according to the connectivity test result between itself and other intelligent equipment; after the voting is finished, the intelligent device with the highest vote count announces itself to be an arbitrator; the online message at least comprises the online state, the IP address and the equipment type of the intelligent equipment, and the equipment information at least comprises the online state, the IP address and the equipment type of the intelligent equipment and the connectivity of the intelligent equipment to other intelligent equipment in the group.
Because the multicast message is adopted to copy only one same data packet, the data transmission efficiency is improved under the condition that the network occupation is smaller, the risk that the arbiter cannot elect due to the fact that a router disables local area network broadcasting in the prior art is avoided, the intelligent equipment with the best network condition can be elected to be an arbiter according to the test result of connectivity, the selected arbiter and other intelligent equipment are in a better connection state, the risk that the arbiter is in poor network connection to cause the wake-up failure of a user is reduced, meanwhile, the local arbitration mechanism of the arbiter is elected through the connectivity voting among the intelligent equipment in the intelligent home system, the time is short, the quick election of the arbiter is realized, the control speed of the intelligent equipment after being on line is accelerated, and the use experience of the user is improved.
Furthermore, the intelligent device votes to the intelligent device with the shortest connection time according to the connectivity test result between the intelligent device and other intelligent devices, and elects to be an arbitrator.
The time consumption of connection between the arbitrator selected by the scheme and most intelligent equipment in the intelligent home system is shorter, so that the wake-up speed of the intelligent home system can be improved, and the user experience is improved.
Furthermore, when the connection time of one intelligent device and a plurality of intelligent devices is the same and is the shortest, voting is carried out according to the preset IP address priority sequence of the intelligent devices, or voting is carried out according to the preset device type priority sequence; when the number of votes of the intelligent devices is highest in parallel, voting is carried out according to the preset IP address priority order of the intelligent devices, or the election result of the arbitrator is determined according to the preset device type priority order.
The setting can more reasonably vote under the condition that the connection time is the same, so as to quickly select the arbiter.
Further, when the connection time of one intelligent device and a plurality of intelligent devices is the same and is the shortest, voting is performed to the intelligent device with the smallest IP address.
Specifically, the method can also be set to vote to the intelligent device with the largest IP address, and the specific selection sequence can be preset by a user or a manufacturer.
Further, when the ticket numbers of the plurality of intelligent devices are highest in parallel, the intelligent device with the smallest IP address is judged to be an arbitrator.
Specifically, the intelligent device with the largest selected IP address may be set as the arbiter, and the specific selection sequence may be preset by the user or the manufacturer.
Further, after receiving the online message, other intelligent devices in the intelligent home system send out their own device information in a multicast message manner, and compare the time interval between themselves and the last connectivity test of the new online intelligent device at the same time, if the time interval is smaller than a fourth preset time period t4, the connectivity test is not performed any more, and the result of the last test is directly used, where the fourth preset time period t4 is a preset time period threshold.
The time interval specifically refers to the time interval between the time when the intelligent device receives the online message and the time when the intelligent device and the new online intelligent device perform the last connectivity test, and the setting can effectively avoid the problem that the network of the individual device is unstable and frequently goes online and offline, so that the network connectivity is repeatedly tested.
Furthermore, when the arbiter finds out that the connection of one intelligent device is interrupted, the arbiter updates the online device information in the device information table of the arbiter, and the arbiter does not reselect.
The connection interruption refers to disconnection of the arbitrator and the tcp socket of the intelligent device or timeout of connection of the heartbeat packet, the setting can ensure running stability of the intelligent home system, and the arbitrator election can not be restarted due to offline of one intelligent device, in this case, the arbitrator updates online information in the device information table, marks the intelligent device as off-line or deletes the intelligent device from the device information table.
Further, when one intelligent device finds that the connection between the intelligent device and the arbiter is interrupted, the intelligent device tries to reconnect the arbiter, if the connection fails, the router gateway where the intelligent device is located is pinned, if the intelligent device is connected, the router gateway waits for a sixth preset time t6, if the intelligent device is not connected with the arbiter in a restoration mode, an equipment on-line message is sent, the arbiter is triggered to reselect, and the sixth preset time t6 is a preset time threshold.
Under the condition of short network fluctuation, reelection of the arbiter cannot occur, and when abnormal conditions such as power failure and network disconnection occur in the arbiter, other intelligent devices in the intelligent home system can initiate reelection of the arbiter as soon as possible, so that the online of the arbiter can be always kept, and the problem of operation paralysis of the intelligent home system caused by the fact that the arbiter is suspended is avoided.
Further, the device information is sent in a device information table mode, after the arbiter is selected, each intelligent device sends the device information table through multicast at intervals of a first preset time period t1, the device information table is used for recording device information of the intelligent device and/or indirectly found intelligent devices, and connection time of the intelligent device to other intelligent devices is consumed, when the intelligent device does not receive the device information table of one intelligent device in a second preset time period t2, the intelligent device is judged to be offline, the intelligent device is deleted from the device information table maintained by the arbiter, the first preset time period t1 and the second preset time period t2 are preset time period thresholds, and t2 is more than t1.
The device information timing device sends the notification to other intelligent devices in the intelligent home system, and the devices in the device information table can be guaranteed to be in an on-line state, so that the election of the arbitrator can be rapidly executed, and false information interference of off-line devices is avoided.
Further, each intelligent device triggers a connection time-consuming test from itself to each intelligent device every third preset time period t3, and refreshes a connection time-consuming field in the device information table, wherein the third preset time period t3 is a preset time period threshold.
The setting can detect the connection time-consuming condition of the intelligent equipment and other intelligent equipment at regular time, is convenient for monitoring the network connection state of the intelligent home system, and ensures continuous maintenance and update of the connection time-consuming in the equipment information table.
The invention also discloses an arbitrator election device, which comprises: the message receiving and transmitting module is used for sending or receiving messages in a multicast mode; the connectivity testing module is used for testing the connectivity between all intelligent devices in the intelligent home system; the equipment information table maintenance module is used for generating and maintaining an updated equipment information table; the voting module is used for carrying out arbitration machine voting according to the connection time consumption of each intelligent device and other intelligent devices; and the arbiter determining module is used for determining the intelligent device with the highest vote number to be an arbiter according to the voting result.

Detailed Description
The present invention will be further described in detail with reference to the drawings and examples, for the purpose of making the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the described embodiments are some, but not all, embodiments of the invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following describes an arbitration election method, an arbitration device, an intelligent device and a computer readable storage medium according to the embodiments of the present invention in detail with reference to the accompanying drawings.
As shown in fig. 1, in the smart home system 1, a plurality of smart devices 11 are located in the same local area network, the plurality of smart devices 11 can communicate with each other in the form of multicast messages, and when a user sends a control command, the corresponding smart device 11 processes the control command.
It should be understood that the control command issued by the user may be a voice control command (including a wake-up command word, a device control command, etc.) of the smart home system 1, or may be another type of command such as a gesture control command. Taking the control instruction as a voice control instruction as an example, after a user wakes up the voice recognition function of one of the intelligent devices 11 through a wake-up command word, not only can the voice control of the intelligent device 11 be realized through the device control command, but also other intelligent devices 11 in the intelligent home system 1 can be controlled through the waken-up intelligent device 11, namely, the distributed voice control function is realized.
In this embodiment, after one intelligent device 11 is networked and connected to the intelligent home system 1, an arbitrator can be elected among the intelligent devices 11, so that when a user sends a control instruction, the elected arbitrator can determine that one intelligent device 11 is most suitable for processing the control instruction of the user in the intelligent home system 1, thereby effectively avoiding that a plurality of intelligent devices 11 respond to the control instruction of the user at the same time and effectively improving the use experience of the user.
In this embodiment, the intelligent device 11 is a voice control device, such as a home appliance including a voice air conditioner, a voice television, a voice refrigerator, and a voice lamp, or may be a common intelligent home appliance, which is not limited thereto.
Example 1
The present embodiment provides an arbitration method, as shown in fig. 2-4, and it should be noted that the arbitration method of the present invention is not limited by the specific order of fig. 2, 3, and 4. It should be understood that, in other embodiments, the order of some steps in the arbitration method of the present invention may be interchanged according to actual needs, or some steps may be omitted or deleted. The arbitration election method can be applied to the intelligent device 11 shown in fig. 1, and can include the following steps:
step S1, after the intelligent equipment 11 is networked and is accessed into the intelligent home system 1, an online message is sent through a multicast message, and an arbiter election is triggered;
in this embodiment, the online message includes at least the online status of the intelligent device 11 itself, an IP (Internet Protocol, a protocol address of interconnection between networks), and a device type, and the setting sends basic information of the intelligent device 11 to other intelligent devices 11 in the group through the online message.
Step S2, after receiving the online message, other intelligent devices 11 in the intelligent home system 1 send out own device information in a multicast message mode, and simultaneously test the connectivity of the own device information to the newly online intelligent devices 11;
in this embodiment, the device information at least includes basic information of the smart device 11 itself, connectivity of the smart device 11 to other smart devices 11 in the group, including an online status, an IP address, a device type, and the like, and connection time consumed when the smart device 11 is reachable or not reachable, and connection time consumed when the smart device is reachable, and the device information is used for the other smart devices 11 in the smart home system 1 to discover and detect connectivity with the new online smart device 11, so as to prepare for an arbitrator election.
Step S3, the newly-online intelligent device 11 receives device information sent back by other intelligent devices 11 in the intelligent home system 1 through multicast messages, and simultaneously tests connectivity between the intelligent device 11 and other intelligent devices 11 in the intelligent home system 1;
the setting enables the newly-online intelligent device 11 to timely find other intelligent devices 11 in the intelligent home system 1, the connectivity between the intelligent device 11 and other intelligent devices 11 can be determined through the connectivity test, the time consumption of connection when the intelligent device 11 is reachable or unreachable or reachable to other intelligent devices 11 is recorded, and preparation is made for subsequent arbitration machine election.
Step S4, the intelligent equipment 11 in the intelligent home system 1 votes for an arbitrator according to the connectivity test result between the intelligent equipment 11 and other intelligent equipment 11;
according to the connectivity test result, the intelligent device 11 with the best network condition can be selected to be an arbitrator, the selected arbitrator and other intelligent devices 11 are in a better connection state, the risk of wake-up failure of a user caused by poor network connection of the arbitrator is reduced, meanwhile, the local arbitration mechanism of the arbitrator is selected through the connectivity voting among the intelligent devices 11 in the intelligent home system 1, the time is short, the quick election of the arbitrator is realized, the control speed of the intelligent devices 11 after being on line is accelerated, and the user experience is improved.
In step S5, after the voting is completed, the intelligent device 11 with the highest vote count announces itself as an arbitrator.
The arrangement enables the intelligent device 11 in the intelligent home system 1 to determine an arbitrator according to the received information, and the determined arbitrator can be used for determining the awakened intelligent device 11 in the intelligent home system 1 when the user sends out the awakening command word by taking the intelligent device 11 as a voice device as an example. In one embodiment, after a user sends a wake-up command word, the intelligent devices 11 with the same wake-up command word can respectively collect the audio energy corresponding to the wake-up command word, the collected audio energy is reported to an arbitrator, the arbitrator determines one intelligent device 11 from the intelligent home system 1 as the awakened intelligent device 11 based on the received audio energy, so that the plurality of intelligent devices 11 with the same wake-up command word are effectively prevented from being awakened, and based on the setting, a simple example is that the user can wake-up the living room television in a living room, and then control the air conditioner of a bedroom through voice interaction of the living room television, thereby obtaining good user experience.
Therefore, in the arbitration machine election method provided by the invention, when the intelligent equipment 11 is accessed into the intelligent home system 1, the arbitration machine is elected in the intelligent home system 1 in a more flexible and intelligent mode by automatically initiating the arbitration machine election flow; meanwhile, the condition that the router disables local area network broadcasting is effectively solved, normal operation of the intelligent home system 1 is ensured, in addition, the selected arbiter is selected by utilizing the connectivity among all intelligent devices 11 in the intelligent home system 1, so that the selected arbiter and other intelligent devices 11 have good connectivity, the response is quicker when a user wakes up, and the use experience of the user is greatly improved.
Specifically, in this embodiment, in the step S4, the arbitration machine is selected according to the connectivity test result between the device itself and the other intelligent devices 11, and specifically includes: the intelligent devices 11 elect an arbitrator according to the connection time consumption of each other intelligent device 11.
As an embodiment of the invention, after the intelligent device 11 obtains the connection time consumption with other intelligent devices 11, selecting one intelligent device 11 with the shortest connection time consumption as an arbitrator, and adopting the arbitrator selected by the scheme to connect with most intelligent devices 11 in the intelligent home system 1 has shorter time consumption, thereby improving the wake-up speed of the intelligent home system 1 and improving the user experience. During election, the device type and the IP address can be used as a device identification means to vote, or after the devices are ordered in the group according to the type and/or the IP address, the voting can be performed according to the ordering sequence number.
It should be understood that when there are more intelligent devices 11 in the smart home system 1, each intelligent device 11 may select more than two intelligent devices 11 to vote when voting, and the intelligent device 11 with the highest vote is finally used as an arbitrator, and the setting may select a relatively stable and fast device connected to all the intelligent devices 11 as the arbitrator, so as to further ensure the stability of the operation of the arbitrator, and ensure the use experience of the user, and it should be understood that each intelligent device 11 may also select at least one intelligent device with short connection time to vote.
As an embodiment of the present invention, each intelligent device 11 selects an arbitrator which is considered suitable by itself according to connection time consumption with other intelligent devices 11, specifically, each intelligent device 11 selects an intelligent device 11 with shortest connection time consumption as an arbitrator, when connection time consumption of one intelligent device 11 and a plurality of intelligent devices 11 is the same and is the shortest, voting is performed according to a preset priority order of IP addresses of the intelligent devices 11 or according to a preset device type priority order, specifically, an intelligent device 11 with a larger IP address may be selected, an intelligent device 11 with a smaller IP address may also be selected, a device type priority order may be preset by a manufacturer or may be set by a user by himself, in this embodiment, in case of presetting priority levels of a living room television-living room air conditioner-first bedroom air conditioner-second bedroom air conditioner-refrigerator-range hood, in case of the same connection time consumption of one intelligent device 11 and a living room air conditioner-refrigerator-range hood, in this embodiment, voting is performed as an arbitrator, in case of a specific IP address selection order and a specific type priority order may not be set in this embodiment, and the method is more reasonable.
It should be understood that, when the number of tickets of the plurality of intelligent devices 11 is highest in parallel, the result of arbitrating machine election is determined according to the preset IP address priority order of the intelligent devices 11 or according to the preset device type priority order, specifically, the intelligent device 11 with the largest IP address may be determined to be the arbitrating machine, or the intelligent device 11 with the smallest IP address may be determined to be the arbitrating machine, or the final result of arbitrating machine election may be determined according to the preset device type priority order, in this embodiment, in the case of the preset priority order of the living room television-living room air conditioner-first bedroom air conditioner-second bedroom air conditioner-washing machine-refrigerator-range hood, when the situation that the ticket number of the living room air conditioner-first bedroom air conditioner-washing machine is the highest and the ticket number is the same occurs, it should be understood that the preset priority order of the IP address and the preset device type priority order include, but are not limited to the above-listed cases, and the priority order of the IP address and/or the device type may be preset by the user, or may be produced by the user.
The preference order rule used when the intelligent device 11 performs voting may be the same as or different from the preference order rule used when determining the arbitrator, as an example, when one intelligent device 11 finds that there are two or more intelligent devices 11 that are connected with the same time and are not the shortest, it may select a preset IP address preference order to perform voting, for example, vote to the intelligent device 11 with the largest IP address or vote to the intelligent device 11 with the smallest IP address, and when two or more intelligent devices with the same number of votes and the highest number of votes occur in the final voting result, may select to determine the arbitrator according to the preset IP address preference order, or may determine the arbitrator according to the preset priority order of the device type, and the specific combination scheme is not specifically limited in this embodiment.
In this embodiment, each of the smart devices 11 in the smart home system 1 may send device information through multicast at each interval for a first preset time period t1, and notify, through device information, the existence of other smart devices 11 in the smart home system 1 at regular time, where the device information includes an on-line state, an IP address, a device type, and the like, and the first preset time period t1 is a preset time period threshold, which may be 5 seconds, 8 seconds, 10 seconds, and the like, and preferably is 5 seconds.
In this embodiment, each of the intelligent devices 11 generates and maintains a device information table, where the device information table is used to record device information of the intelligent device 11 that is found by itself and/or indirectly, and connection time of the intelligent device 11 to other intelligent devices 11 is consumed, it should be understood that in this case, each intelligent device 11 sends out a device information table that is maintained by itself through multicast at intervals of a first preset time period t1.
Specifically, when the intelligent device 11 does not receive the device information table of a certain intelligent device 11 within the second preset time period, the device is determined to be offline, and is deleted from the device information table maintained by itself, where the second preset time period t2 is a preset time period threshold value, and t2 is greater than t1, in this embodiment, the second preset time period t2 may be 20 seconds, 30 seconds, 40 seconds, and preferably 30 seconds, and the setting may ensure that devices in the device information table are all in an online state, so as to quickly execute election of the arbiter, and avoid false information interference of the offline device.
Preferably, each intelligent device 11 triggers a connection time consuming test from itself to each intelligent device 11 every third preset time period t3, and refreshes a connection time consuming field in a corresponding device information table, where the third preset time period t3 is a preset time period threshold, in this embodiment, the third preset time period t3 may be 8 minutes, 10 minutes, 12 minutes, and the like, preferably 10 minutes, and the setting may be used to detect the connection time consuming condition of the intelligent device 11 and other intelligent devices 11 at regular time, so as to monitor the network connection state of the intelligent home system 1, and ensure continuous maintenance and update of connection time consuming in the device information table.
It should be noted that, when receiving the online message sent by the new online smart device 11, the step S2 executed by the other smart devices 11 in the smart home system 1 specifically includes:
step S21, transmitting the self-maintained equipment information table in a multicast mode;
this setup may help the new online intelligent device 11 discover other devices within the local area network quickly.
Step S211, comparing the time interval between the intelligent device 11 and the last connectivity test of the new online intelligent device, if the time interval is smaller than a fourth preset time period t4, directly using the result of the last test, and not executing step S22; if not less than the fourth preset time period t4, executing step S22;
the time interval specifically refers to a time interval between when the intelligent device 11 receives the online message and a time interval between when the intelligent device 11 and a new online intelligent device 11 perform a last connectivity test, and the setting can effectively avoid a problem that an individual device network is unstable and frequently goes online and offline, so as to cause repeated testing of network connectivity, and the fourth preset time period t4 is a preset time period threshold, and in this embodiment, the fourth preset time period t4 may be 8 seconds, 10 seconds, 12 seconds, and preferably 10 seconds.
Step S22, testing the connection between itself and the new online intelligent device 11 is time-consuming.
Preferably, the following steps may be further performed before the step S211 is performed:
step S210, detecting whether there is a new online smart device 11 in the device information table maintained by the device itself, if yes, executing step S211, and if no, executing step S22.
The setting can determine whether the newly-online intelligent device 11 has the problem of frequent online and offline according to the device information table, and can directly test connectivity of the intelligent device 11 which is not frequently online and offline, so that a time length judging link is avoided.
When the new online intelligent device 11 receives the device information table sent by other intelligent devices 11 in the group, the following steps are executed:
s31: synchronizing other information except the connection and connection time-consuming information in the device information table into the device information table maintained by the device information table, and simultaneously testing the connectivity of the device information table and the intelligent devices 11.
Optionally, the intelligent device 11 in the intelligent home system 1 may vote after completing the connectivity test with the new online intelligent device 11, where the new online intelligent device 11 may vote after completing the connectivity test with other intelligent devices 11 after sending the online message for a fifth predetermined time period t5, where the fifth predetermined time period t5 is a predetermined time period threshold, in this embodiment, the fifth predetermined time period t5 may be 1 second, 2 seconds, 3 seconds, and preferably be 2 seconds, and this setting may ensure that voting is performed after completing the connectivity test, thereby ensuring the timeliness and accuracy of voting.
Optionally, as shown in fig. 4, the arbitration machine election method provided by the present invention further includes:
step S6, when the arbiter finds out that the connection of one intelligent device 11 is interrupted, the arbiter updates the online device information in the device information table of the intelligent device, and the arbiter does not reselect.
It should be noted that in this embodiment, the connection interruption refers to disconnection of the arbitrator from the tcp socket connection of the smart device 11 or timeout of the heartbeat packet connection, and this setting can ensure operation stability of the smart home system 1, and the arbitrator election will not be restarted due to offline of one smart device 11, in which case, the arbitrator updates online information in its device information table, and marks the smart device 11 as being offline or deletes it from the device information table.
Alternatively, as shown in fig. 4, the arbitration machine election method provided by the present invention further includes:
step S7, when one intelligent device 11 finds that the connection between the intelligent device and the arbiter is interrupted, the arbiter is tried to be reconnected, and if the connection fails, step S71 is executed;
step S71, ping the router gateway where the intelligent device 11 is located, if the router gateway is connected, executing step S72;
step S72, wait for the sixth predetermined duration t6, if the connection with the arbiter is restored, then the operation is normal, if the connection with the arbiter is not restored, then send the equipment on-line message, trigger the arbiter to reselect.
If the intelligent device 11 is successfully reconnected to the arbiter, normal operation is continued, and the arbiter reselection is not initiated, in step S71, if the intelligent device 11 is not connected, the network connection is interrupted, in step S72, the recovery connection indicates that the tcp socket connection between the intelligent device 11 and the arbiter is recovered, the heartbeat packet is normal, the device information table or the announcement message sent by the arbiter is received, and if the connection is recovered during a sixth predetermined time period t6, the temporary network fluctuation is indicated, the arbiter is not required to be reselected, wherein the sixth predetermined time period t6 is a preset time period threshold, and in the embodiment, the first predetermined time period t6 is 5 seconds. Under the condition of short network fluctuation, reelection of the arbiter cannot occur, and when abnormal conditions such as power failure and network disconnection occur in the arbiter, other intelligent devices 11 in the intelligent home system 1 can initiate reelection of the arbiter as soon as possible, so that the online of one arbiter can be always kept, and the problem of running paralysis of the intelligent home system 1 cannot occur due to the fact that the arbiter is suspended.
It should be appreciated that when the intelligent device 11 does not receive the device information returned by other intelligent devices 11 within the fifth predetermined time period t5 after sending the online message, the voting choice itself is a referee, and no connectivity detection is performed.
