Micro-power wireless frequency-locking communication method and apparatus

[0046] Example one:

[0047] See figure 1 , A schematic flowchart of an embodiment of a micro-power wireless frequency-locked communication method according to an embodiment of the present invention.

[0048] An embodiment of a micro-power wireless frequency-locked communication method provided by an embodiment of the present invention includes:

[0049] S101. Cyclic switching between at least two channels every preset time interval by the frequency hopping timer, scanning the preamble of the channel and saving the RSSI value of the preamble obtained by scanning.

[0050] When setting multiple channels, you need to set the frequency hopping time of the frequency hopping timer to switch back and forth in each channel and monitor the preamble signal, that is, the frequency hopping timer interval is set to a fixed duration ( For example, 6ms, it can be set according to actual needs, and there is no specific limitation here), the channel is switched every fixed time length, and the preamble

[0059] Embodiment two:

[0060] See figure 2 , A schematic flowchart of another embodiment of a micro-power wireless frequency-locked communication method according to an embodiment of the present invention.

[0061] See image 3 , A schematic flowchart of a specific implementation manner of a micro-power wireless frequency-locked communication method provided by an embodiment of the present invention.

[0062] A micro-power wireless frequency-locked communication method provided by an embodiment of the present invention includes:

[0063] S201: Cyclic switching between the at least two channels every preset time interval by the frequency hopping timer, scanning the preamble of the channel and saving the RSSI value of the preamble obtained by scanning.

[0064] The implementation of S201 is similar to that of S101, and will not be repeated here.

[0065] S202. After completing a preset round of scanning for all channels, determine whether the receiving end node of the channel is in the net

[0082] Embodiment three:

[0083] See Figure 4 , A schematic structural diagram of a micro-power wireless frequency-locked communication device provided by an embodiment of the present invention.

[0084] A micro-power wireless frequency-locked communication device provided by an embodiment of the present invention includes:

[0085] The scanning module 301 is configured to cyclically switch between at least two channels every preset time interval through the frequency hopping timer, scan the preamble of the channel and save the RSSI value of the preamble obtained by scanning.

[0086] The scanning module 301 specifically includes:

[0087] The scanning sub-module 3011 is used to read and save the RSSI value of the preamble when the preamble is scanned in one channel, and complete the scanning of the preamble and the RSSI value of the preamble obtained in the order in the remaining channels Save.

[0088] The judging module 302 is configured to judge the priority of the channels whose pr
