Problems solved by technology

If the gateway is down, the state of the associated switch cannot be synchronized, and multi-controllers will have problems. For example, after the switch is operated to turn on the light, if the switch and the switch cannot be synchronized, the next operation, if the light is turned off by operation , because the current state of the switch is still off, so this operation will be considered as turning on the lights, and the lights cannot be turned off normally. It must be operated twice to complete the lights off, and if the gateway still does not recover at this time, the three switches are still Unable to achieve state synchronization, resulting in the confusion of the three switch states, and the user experience will also be reduced
[0004] Moreover, due to the long delay and low efficiency, in the case of frequent switching lights (such as children playing the game of turning on the lights), the gateway may receive contradictory signals multiple times in a short period of time (one signal has not been processed, and another one comes over). There are contradictory signals, and there are multiple such repeated signals in a short period of time) and there is a problem of downtime

Embodiment 1

[0034] This embodiment provides a method for synchronizing the state of the linkage switch 2 of the multi-control unit 1 in the whole house intelligent system. control equipment, such as figure 1 As shown, the state synchronization of each linkage switch 2 in the multi-control unit 1 from the gateway 3 is realized in the following manner:

[0035] S1. A linkage switch 2 state change;

[0036] S2. The linkage switch 2 sends a status message to all other linkage switches 2 in the multi-control unit 1;

[0037] S3. After receiving the status message, all other linkage switches 2 synchronize the status according to the message, and finally complete the status synchronization;

[0038] S4. All the linkage switches 2 in the multi-control unit 1 report the state information to the gateway 3 respectively or any one of the linkage switches 2 reports the state information to the gateway 3 . The gateway 3 then synchronizes the state information to the corresponding APP.

[0039] In t...

Embodiment 2

[0042] This embodiment is similar to Embodiment 1, the difference is that, as figure 2 As shown, in this embodiment, the gateway 3 designates one linkage switch 2 as the virtual master for each multi-control unit 1 . And the gateway 3 establishes the binding relationship between the virtual master and all other linkage switches 2 in the unit in the virtual master, and after the status of the virtual master changes, the status message is sent to all other linkage switches 2 in the multi-control unit 1 according to the binding relationship. linkage switch 2; at the same time, establish a binding relationship between the corresponding linkage switch 2 and the virtual master in other linkage switches 2.

[0043] Specific methods such as image 3 Shown:

[0044] S1. A linkage switch 2 state change;

[0045] S2. The linkage switch 2 judges whether it is a virtual master, if so, execute step S3, otherwise, execute step S4;

[0046]S3. Send a status message to all other linkage s...

Embodiment 3

[0053] In the second embodiment, the concept of virtual master control is proposed, and a linkage switch 2 is designated as the virtual master control, so as to greatly reduce unnecessary communication messages and improve synchronization efficiency. Linkage switch 2 has basically zero pressure compared to gateway 3, so the downtime probability of linkage switch 2 is much lower than that of gateway 3, but the low probability does not mean that it is completely impossible to happen. In the case of virtual master downtime , the remaining normal linkage switches 2 in the multi-control unit 1 cannot perform state synchronization. This embodiment proposes a master control self-recovery method for the situation that the linkage switch 2 may have a downtime problem.

[0054] In the whole house intelligent system, the gateway 3 is connected to all smart devices, and the gateway 3 side can know the online and offline status of all smart devices. This embodiment is based on this feature...

Abstract

The invention discloses a linked switch state synchronization method for multi-control units in a whole house intelligent system. Each multi-control unit comprises a plurality of linked switches, and the state synchronization of the linked switches in the multi-control units is realized through the following modes: S1, the state of one linked switch is changed; s2, the linked switch sends a state message to other linked switches in the unit; S3, other linked switches synchronize the state according to the message after receiving the state message. According to the scheme, all linked switches in the multi-control unit are 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 barrier-free synchronization can still be realized even if the gateway crashes.

Description

technical field [0001] The invention belongs to the technical field of whole-house intelligent systems, and in particular relates to a method for synchronizing the states of linkage switches of multiple control units in the whole-house intelligent system. Background technique [0002] In a smart scenario, when multiple switches correspond to the same controlled device, these switches are interrelated linkage switches. If one linkage switch is operated, the other linkage switches need to be synchronized in state, such as A switch, B switch, and C switch. The switches are all switching devices used to control the D light. When the A switch is operated to turn on the D light, the three switches should be switched from the off state to the on state. Since the A switch is operated, it is directly switched to the on state. , but the B and C switches are not operated, and need to be switched to the ON state in a synchronous manner. The traditional synchronization method is that th...
