Embodiment Construction
[0083] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0084] refer to figure 1 , shows the step flow of a channel switching method embodiment of a zigbee network of the present invention Figure 1 , specifically may include the following steps:
[0085] Step 101, calculating the online rate of one or more network nodes in the zigbee network, and / or the offline rate, and / or the repeated online rate;
[0086] When the zigbee network and the WiFi network coexist, because the WiFi network will seriously affect the throughput and packet loss rate of the ZigBee system, the network nodes in the zigbee network will be disconnected and reconnected after being disconnected. In order to calculate the online rate, and / or offline rate, and / or repeated online rate of a network node, it is necess...

The embodiment of the invention provides an interference detection channel switching method for a Zigbee network. The method comprises the following steps of calculating the online rate, and / or the line disconnecting rate, and / or the repeated online rate of one or more network nodes in the ZIGBEE network; comparing the online rate with a preset online rate threshold value, and / or comparing the line disconnecting rate with a preset line disconnecting rate threshold value, and / or comparing the repeated online rate with a preset repeated online rate threshold value; based on the above comparison result, determining whether the interference exists in a channel currently used by the above one or more network nodes or not. According to the embodiment of the invention, even when the communication cannot be normally conducted due to the serious interference of WIFI signals or WIFI signals around energy detection equipment cannot reach an energy threshold value or in other extreme conditions, whether signals are interfered or not can still be detected. Meanwhile, the channels of network nodes in the Zigbee network can be switched. Therefore, the online stability of the network nodes in the zigbee network is improved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a channel switching method of a Zigbee network and a channel switching device of the Zigbee network. Background technique [0002] ZigBee technology is a short-distance, low-power wireless communication technology based on IEEE802.15.4 standard low-power LAN protocol, which is characterized by short distance, low complexity, self-organization, low power consumption, and low data rate. [0003] WiFi based on IEEE802.11b standard is the mainstream technology of wireless LAN today. As the market demand for low-speed applications continues to grow, there are more and more application scenarios that require the coexistence of ZigBee and WiFi systems. But because both of them mainly work in the free frequency band (ISM Band, Industrial Scientific Medical Band) of 2.4GHz industry, science and medicine, they will inevitably produce mutual interference, so how to eliminate interfer...
