The invention provides a gateway recovery method which can be executed in an intelligent home environment shown in fig. 1. Fig. 2 is a schematic diagram of a gateway recovery method according to an embodiment of the present invention. A gateway restoration method in an embodiment of the present invention is explained below with reference to fig. 2. The gateway recovery method in the embodiment of the invention comprises the following steps:
In an embodiment of the present invention, the first gateway refers to a network device connecting an Intranet (Intranet) and an extranet (Internet). The first gateway may operate for a long time or may malfunction under the influence of an external environment (e.g., water ingress, high temperature, etc.). When the first gateway fails, the device connected to the external network through the first gateway loses network connection and cannot communicate with the external network.
The first gateway stores configuration information, and the configuration information may include gateway coordinator information, network information, and network device information. The gateway coordinator information may include a MAC address (MAC address). The network information may include a network key (network key), a PAN ID (personal area network ID), and channel (channel) information. The network device information may include device type, location, etc. Taking the door and window sensor as an example, the network device information may include that the device type is the door and window sensor and the location is the balcony. Through the gateway coordinator information, the network information and the network device information, a plurality of network devices and gateways can be assembled into a network.
In some embodiments of the present invention, the configuration information of the first gateway further includes room information, automation scheme information, and scenario information, and the network recovery method further includes uploading the room information, automation scheme information, and scenario information to the cloud server. The room information may include the number of rooms, the orientations of the rooms, and the positional relationship between the rooms. The automation scheme refers to a constructed linkage relationship between gateways or network devices connected to the gateways, the automation scheme may include a trigger condition and an execution action, the devices in the automation scheme may include a trigger device and a controlled device, and when the trigger device satisfies the trigger condition, the controlled device executes the corresponding execution action. The automation scenario information may include trigger devices, trigger conditions, controlled devices, and execution actions. Taking the lighting of the door as an example, the triggering device is a door, the triggering condition is that the door is opened, the controlled device is a lamp, and the executing action is the lighting.
The scene is a preset scene corresponding to the selection of the user from different scenes preset in advance according to the selection of the user. For example, when the user selects to enter a movie scene, the lights in the living room are turned off, and the television and the sound are turned on. The scene information may include a scene name, a scene device and a scene device action, and the like.
In this step, the configuration information of the first gateway is backed up to the cloud server. The first gateway may be connected to the router, and then the configuration information of the first gateway is backed up to the cloud server through the router. The router may be connected to the cloud server through a wired network or may be connected to the cloud server through a wireless network.
The configuration information of the first gateway updated in real time may be backed up to the cloud server. In this embodiment, when the configuration information of the first gateway is updated, the configuration information of the first gateway, which is subjected to updating, is backed up to the cloud server. For example, the user operation changes the automation information of the door and window sensor so as to stop the door and window sensor from working when cleaning the door and window, and the automation information of the changed door and window sensor is backed up to the cloud. By backing up the configuration information of the first gateway updated in real time to the cloud server, the user operation can be correspondingly carried out, and the intelligence is improved.
The configuration information of the first gateway may be backed up to the cloud server at a preset period. The configuration information of the first gateway can be backed up to the cloud server at preset periods by connecting the first gateway to the oscillating circuit. The predetermined period may be the same as the period of the oscillator circuit. The preset period may be associated with a routine detection period of the first gateway. The user can also adjust the preset period through the user interaction interface.
The step of detecting whether the first gateway has failed may comprise: acquiring the network connection quality of a first gateway; and when the network connection quality is lower than a first preset value, judging that the first gateway is detected to have a fault. The network connection quality of the first gateway may be determined based on a delay time for transceiving the current network connection probe packet. The network connection quality of the first gateway can also be determined according to the delay time of the historical data transceiving.
As a non-limiting example, the first preset value is a delay time of 100ms, and when the delay time for transceiving the network connection probe packet or the historical data is greater than 100ms, the network connection quality is lower than the first preset value, and it is determined that the first gateway has failed.
In embodiments of the invention, the second gateway may refer to a gateway that is state-healthy or has a short lifetime. And when the first gateway is detected to be out of order, connecting the second gateway to the cloud server, and downloading the configuration information from the cloud server. In an embodiment where the configuration information of the first gateway includes room information, automation scheme information, and scenario information, it may further include downloading the room information, automation scheme information, and scenario information from a cloud server at the second gateway.
After step 220, network connection can be established between the second gateway and the network device according to the configuration information and the network information, so that communication is performed between the second gateway and the network device, a complete intelligent home system network can be established, and remote control and linkage control of the user on the intelligent network device can be realized. The network connection between the second gateway and the network device may be a wired connection or a wireless connection. The wireless connection can be established in a bluetooth protocol, a Wi-Fi protocol, a ZigBee protocol, or the like, which is not limited herein.
Flow charts are used herein to illustrate the operations performed by methods according to embodiments of the present invention. It should be understood that the preceding operations are not necessarily performed in the exact order in which they are performed. Rather, various steps may be processed in reverse order or simultaneously. Meanwhile, other operations are added to or removed from these processes.
