Description
Technical Field
The invention belongs to the technical field of whole-house intelligent systems, and particularly relates to a linkage switch state synchronization method of multiple control units in a whole-house intelligent system.
Background
In an intelligent scene, when a plurality of switches correspond to the same controlled device, the switches are the linked switches which are associated with each other, if one linked switch is operated, the other linked switches need to be in state synchronization, for example, the switch a, the switch B and the switch C are all switch devices for controlling a D lamp, when the switch a is operated to turn on the D lamp, the three switches should be switched from the off state to the on state, because the switch a is operated, the switch a is directly switched to the on state, but the switch B and the switch C are not operated and need to be switched to the on state in a synchronization mode. The traditional synchronization mode is that the switch A reports the state information to the gateway, the gateway issues the state to the B and the C, and then the B and the C switch to the on state according to the state information issued by the gateway to realize synchronization. However, in such a method, a gateway is needed, and the gateway is a heart of an intelligent internet of things system, and plays a plurality of tasks, and more messages are transmitted and received at every moment, so that the method for realizing synchronization through the gateway has the problems of low efficiency and high delay.
In addition, because the state synchronization needs to use the gateway which is a central node of the whole-house intelligent system, the network pressure is high, and the possibility of paralysis is also highest. If the gateway is down, the associated switches cannot realize state synchronization, and multiple controls cause problems, for example, after the operation switches are turned on, if the switches and the switches cannot be synchronized, and the switches are turned off by operation next time, if the switches are turned off by operation, the current state of the switches is still off, so that the operation is regarded as the operation of turning on the lamps, the lamps cannot be normally turned off, the lamps must be turned off by two operations, and if the gateway is still not recovered at this time, three switches cannot realize state synchronization, so that the problem of confusion of three switch states is caused, and the user experience is also reduced.
Moreover, due to the long delay time and the low efficiency, under the condition of frequent light turning on and off (such as children playing light-on games), the problem that the gateway is down due to the fact that contradictory signals are received for many times in a short time (one signal is not processed, the other contradictory signal is received, and a plurality of signals are repeated in the short time).

In the state synchronization method for the multi-control switches in the whole house intelligent system, one of the ganged switches in the multi-control units is designated as the virtual master control by the gateway in the corresponding whole house intelligent system.
In the above method for synchronizing the states of the multi-control switches in the whole-house intelligent system, when the gateway detects that the ganged switch designated as the virtual master control is offline, other ganged switches are changed to serve as the virtual master control of the corresponding multi-control unit.
In the above method for synchronizing the states of the multi-control switches in the whole-house intelligent system, after the step S3, the method further includes:
and S4, reporting the state information to the gateway by at least one linkage switch.
In the above method for synchronizing the states of the multi-control switches in the whole-house intelligent system, in step S4, the virtual master controller reports the state information to the gateway.
The invention has the advantages that:
each linkage switch in the multi-control unit is directly synchronized without passing through a gateway, so that the method has the advantages of high synchronization speed, no influence of a gateway network and the like, and the gateway can be synchronized without obstacles even if the gateway is down;

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The whole-house intelligent system in the scheme is an intelligent system applied to the fields of families, hotels, offices, endowments, education and the like, for example, an intelligent home system, based on a Zigbee network, and a Zigbee gateway and a switch device connected to the Zigbee gateway through the Zigbee network are arranged in one scene, and the method is mainly a multi-control switch state synchronization method based on a Zigbee3.0 network. In a typical home scenario, there will be a plurality of multiple control units 1, each multiple control unit 1 comprising two or three ganged switches 2 and one controlled device, such as a lamp, controlled by all ganged switches 2 in the respective multiple control unit 1. In other scenes with larger volume, more multi-control units 1 exist, and more than three multi-control units 1 of the ganged switch 2 also exist. In the prior art, each time the state of the multi-control unit 1 is switched, all the associated ganged switches 2 need to be synchronized through the gateway 3, a large amount of network space is occupied, and the network occupation problem, the synchronization delay problem and the like are more prominent in the scene that the more the multi-control units 1 are, the more the ganged switches 2 are. According to the scheme, a synchronous mode without passing through the gateway 3 is realized through a special technical means, state synchronization is directly completed by the gang switch 2, the network pressure of the gateway 3 can be greatly reduced, and meanwhile, the problems of synchronous delay caused by network problems and congestion problems of the gateway 3, the problem that state synchronization cannot be realized due to breakdown of the gateway 3 and the like are solved.
Example one
The embodiment provides a method for synchronizing the states of ganged switches 2 of multiple control units 1 in a whole-house intelligent system, wherein each multiple control unit 1 comprises a plurality of mutually associated ganged switches 2, the ganged switches 2 are used for controlling one controlled device in a linkage manner, and as shown in fig. 1, the state synchronization of the state that each ganged switch 2 in the multiple control unit 1 is separated from a gateway 3 is realized by the following specific method:
s1, changing the state of a linkage switch 2;
s2, the linked switch 2 sends a state message to all other linked switches 2 in the multi-control unit 1;
s3, after receiving the state messages, all other linked switches 2 finish state synchronization according to the message synchronization state;
and S4, reporting the state information to the gateway 3 by all the ganged switches 2 in the multi-control unit 1 or reporting the state information to the gateway 3 by any one ganged switch 2. The gateway 3 synchronizes the state information to the corresponding APP.
In this embodiment, all the ganged switches 2 in the multi-control unit 1 have a binding relationship with other ganged switches 2 in the unit, and the binding relationship is sent to each ganged switch 2 by the gateway 3. And after the state of any linkage switch 2 is changed, the state message is sent to other linkage switches 2 in the unit according to the binding relationship so as to realize state synchronization.
According to the scheme, the state messages are directly sent to other ganged switches 2 in the unit when the states of the ganged switches 2 are changed, the other ganged switches 2 are directly in message synchronization states, the ganged switches do not need to pass through the gateway 3, the ganged switches can be completely separated from the gateway 3 to achieve a multi-control function, the ganged switches are not influenced by the network of the gateway 3, the synchronous steps can not cause pressure on the gateway 3, and the speed of the gateway 3 for processing other tasks is indirectly increased. And all the multi-control units 1 in the same network are independent in the state synchronization process, and no matter how many multi-control units 1 exist in the network, the synchronization of other multi-control units 1 cannot be influenced.
Example two
The present embodiment is similar to the embodiment, except that, as shown in fig. 2, the gateway 3 designates one of the ganged switches 2 as a virtual master for each multi-control unit 1 in the present embodiment. The gateway 3 establishes a binding relationship between the virtual master control and all other ganged switches 2 in the unit in the virtual master control, and sends a state message to all other ganged switches 2 in the multi-control unit 1 according to the binding relationship after the state of the virtual master control is changed; and meanwhile, establishing the binding relationship between the corresponding linked switch 2 and the virtual master control in other linked switches 2.
The specific method is shown in fig. 3:
s1, changing the state of a linkage switch 2;
s2, the linked switch 2 judges whether the linked switch is a virtual master control, if so, the step S3 is executed, otherwise, the step S4 is executed;
s3, sending the state message to all other ganged switches 2 in the multi-control unit 1, and synchronizing the state according to the message after the other ganged switches 2 receive the state message;
s4, sending a state message to the linkage switch 2 serving as the virtual master control, sending the state message to all other linkage switches 2 in the multi-control unit 1 after the virtual master control synchronizes the state according to the message, and synchronizing the state according to the message after the linkage switch 2 receives the state message;
and S5, reporting the state information to the gateway 3 by all the linked switches 2 in the multi-control unit 1 respectively, or reporting the state information to the gateway 3 by the virtual main control. The gateway 3 synchronizes the state information to the corresponding APP.
In step S4, the other unsynchronized ganged switches 2 synchronize states according to the message after receiving the state message sent by the virtual master control, and the synchronized ganged switch 2 mainly refers to the ganged switch 2 in step S1, and the states thereof are switched without resynchronization.
The method is exemplified by a scene with four ganged switches a, B, C and D2 in one multi-control unit 1: the switch A is designated as a virtual master control, when the state of the switch A changes due to operation, because the binding relationship between the switch A and the switches B, C and D is recorded in the switch A, the switch A sends a state message to the switches B, C and D, and the switches B, C and D return the state message to the switch A after the synchronization state to complete synchronization; when the switch B changes state due to operation, the switch B records the binding relationship with the switch A, so that a state message is sent to the switch A, the switch A sends the state message to the switches B, C and D according to the binding relationship after changing the state according to the message, at the moment, the state synchronization between the switches A and B is completed, the switches C and D return the state message to the switch A after receiving the state message according to the message synchronization state to complete the synchronization, and all the linkage switches 2 in the unit complete the state synchronization.
In the first embodiment, since all the ganged switches 2 are equal, the ganged switches 2 after synchronizing according to the status message will send the status message to all other ganged switches 2 in the unit because the status changes, so that there are many communication messages in the whole synchronization process. For example, four linked switches 2 of a, B, C and D are arranged in a multi-control unit 1, a switch sends state messages to B, C and D after being operated to change the state, a switch of B can also send state messages to a, C and D after changing the state according to the state messages, and similarly, a switch of C can also send state messages to a, B and D after changing the state according to the state messages, and a switch of D can also send state messages to a, B and C after changing the state according to the state messages. Finally, the state synchronization of all the ganged switches 2 in the whole multi-control unit 1 is completed only after the switch A confirms that the ganged switches are in the state consistent with the state messages respectively sent by the switches B, C and D, the switch B confirms that the ganged switches are in the state consistent with the state messages respectively sent by the switches A, C and D, the switch C confirms that the ganged switches are in the state consistent with the state messages respectively sent by the switches A, B and C, and the switch D confirms that the ganged switches are in the state consistent with the state messages respectively sent by the switches A, B and C. Therefore, although there are still many advantages to the state synchronization method through the gateway 3 in the first embodiment, there still exists a significant disadvantage that the synchronization delay problem still exists. The scheme further improves the defects still existing in the first embodiment, the linked switch 2 serving as the virtual master control is used for communicating with other linked switches 2 to carry out state synchronization in a mode of designating one linked switch 2 as the virtual master control, the problem that each linked switch 2 sends a state message to the other linked switches 2 cannot occur, the number of messages in the state synchronization process can be effectively reduced, the synchronization efficiency is improved, and the synchronization delay problem is solved.
EXAMPLE III
In the second embodiment, a virtual master control concept is proposed, and one ganged switch 2 is designated as a virtual master control, so that unnecessary communication messages are greatly reduced, and the synchronization efficiency is improved. The ganged switches 2 are at substantially zero pressure relative to the gateways 3, so the probability of downtime of the ganged switches 2 is much lower than the gateways 3, but the low probability does not mean that it is completely impossible, and in the event of a downtime of the virtual master control, the remaining normal ganged switches 2 in the multi-control unit 1 cannot be state-synchronized. The embodiment provides a main control self-recovery means for the situation that the ganged switch 2 may be down.
In the whole-house intelligent system, the gateway 3 is networked with all the intelligent devices, the gateway 3 side can know the online and offline conditions of all the intelligent devices, and in case that the ganged switch 2 serving as the main control is down, the gateway 3 appoints the main control again based on the characteristic of the whole-house intelligent system to realize main control self-recovery under the condition that the virtual main control is down, so that the stability and the safety of the synchronous network are ensured, as shown in fig. 4, the specific method is as follows:
when the gateway 3 detects that the ganged switch 2 designated as the virtual master is offline, other ganged switches 2 are changed to be used as the virtual master of the corresponding multi-control unit 1, and the condition that the ganged switch 2 is offline includes the condition that the ganged switch 2 is offline in a fault, or the ganged switch 2 is deleted offline and the like.
The change mode is that other ganged switches 2 are appointed to be used as virtual main control of the corresponding multi-control unit 1, and the binding relation in each ganged switch 2 is changed; when the linkage switch which is originally the virtual master control is on line again, the virtual master control identity is cancelled, and meanwhile, the binding relationship of the linkage switch which is originally the virtual master control is changed, namely, the original binding relationship with all other linkage switches in the unit is changed into the binding relationship with the newly appointed virtual master control. The re-online comprises the situations of re-online, re-joining and the like.
Of course, the gateway 3 may send the offline condition to the corresponding APP and inform the user that the ganged switch 2 is currently in the offline state. In addition, the gateway 3 changes the binding relationship among the respective gang switches 2 while changing the designated virtual master.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
Although multi-control unit 1 is used more herein; a ganged switch 2; gateway 3, etc., without excluding the possibility of using other terms. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
