In the former method, the network-connected device regularly reports the device status to the gateway. When the device suddenly loses power, the device can no longer report the gateway status, and the gateway cannot obtain the offline status of the device in time. In the latter method, the gateway periodically queries the network-connected device for the device state, when the number of devices connected to the network reaches a certain level, a large number of devices communicating at the same time will greatly increase the burden on the communication network, and it is also not conducive to improving the standby time of passive devices

The invention discloses a method and a device for identifying an off-line state and an on-line state of ZigBee equipment. The method comprises the steps of enabling a ZigBee gateway to acquire the equipment type of ZigBee equipment; according to the equipment type of the ZigBee equipment, determining a state reporting time interval of the ZigBee equipment; receiving the equipment state reported bythe ZigBee equipment according to the state reporting time interval of the ZigBee equipment; when it is determined that the equipment state reported by the ZigBee equipment is not received continuously for a first preset number of times, sending a state query request to the ZigBee equipment; if the state query result is not received after the preset time, sending the state query request again; and when the state query result is not received, setting the offline state of the ZigBee equipment to be an offline state. Different reporting time intervals are set through different types of equipment, so that the timeliness rate and the accuracy rate of identifying whether the network access equipment is online or not by the ZigBee gateway are improved.
Description
technical field [0001] The embodiment of the present invention relates to the field of smart home technology, and in particular to a method and device for identifying the offline state of a ZigBee device. Background technique [0002] At present, in the field of smart home, the Zigbee wireless communication protocol is a common transmission method for communication between the gateway end and the device end. When the gateway identifies whether the network-connected device is online, it usually uses the method that the network-connected device actively reports the device status to the gateway at regular intervals or the gateway regularly actively queries each network-connected device for the status of the device. In the former method, the network-connected device regularly reports the device status to the gateway. When the device suddenly loses power, the device can no longer report the gateway status, and the gateway cannot obtain the offline status of the device in time. In...
