13. acquiring a target channel parameter set corresponding to the target channel set;
14. and selecting the first channel parameter corresponding to the first communication channel.
In a specific implementation, the communication channels corresponding to different positions are different, for example, if the user moves in the environment of the internet of things, the communication channels corresponding to different positions are also different, the electronic device may obtain the target position, a mapping relationship between a preset position and a channel set may be pre-stored in the electronic device, a target channel set corresponding to the target position may be determined according to the mapping relationship between the preset position and the channel set, the target channel set may include a plurality of communication channels, a target channel parameter set corresponding to the target channel set, different communication channels, corresponding to different channel parameters, and a first channel parameter corresponding to the first communication channel may be selected, so that the communication channel corresponding to the electronic device and the channel parameter corresponding to the communication channel may be accurately determined according to the position of the electronic device, the method is beneficial to realizing accurate channel monitoring and providing a basis for subsequent channel switching.
102. And when the first channel parameter meets a preset condition, acquiring a second communication channel between the electronic equipment and the target Internet of things equipment.
The preset condition may be set by the user or default by the system, for example, when the first channel parameter is the packet loss rate, the packet loss rate is greater than the preset packet loss rate, it is determined that the first channel parameter meets the preset condition, and the preset packet loss rate may be set by the user or default by the system. In specific implementation, the electronic device may obtain a second communication channel between the electronic device and the target internet of things device when the first channel parameter satisfies a preset condition, where the second communication channel may be understood as a standby communication channel, for example, when the current channel quality is poor or the current channel communication is interrupted, the electronic device may be switched to the second communication channel to continue to complete communication, otherwise, when the first channel parameter does not satisfy the preset condition, the electronic device may continue to implement communication between the electronic device and the target internet of things device through the first communication channel.
In one possible example, the step 102 of acquiring the second communication channel between the electronic device and the target internet of things device may include the following steps:

231. sending a test signal to a reference communication channel i, wherein the reference communication channel i is any one of the reference communication channels;
232. receiving feedback parameters returned by the reference communication channel i, wherein the feedback parameters comprise a target packet loss rate and a target transmission duration;
233. determining the number of target transfer devices corresponding to the reference communication channel i;
234. determining a target first channel quality value corresponding to the target packet loss rate according to a mapping relation between a preset packet loss rate and the first channel quality value;

235. and performing weighted operation according to the target weight value, the target first channel quality value and the target second channel quality value to obtain a channel quality value corresponding to the reference communication channel i.
In a specific implementation, the feedback parameters may include: packet loss rate and transmission duration. For different transmission paths, the number of target relay devices corresponding to the transmission paths is different, and taking the transmission path i as an example, the transmission path i is any one of multiple transmission paths, so that the electronic device may determine the number of target relay devices corresponding to the transmission path i, and a packet loss rate i and a transmission duration i corresponding to the transmission path i.
Further, the electronic device may pre-store a mapping relationship between a preset packet loss rate and the first channel quality value, and a mapping relationship between a preset transmission time and the second channel quality value, and further, the electronic device may determine the target first channel quality value corresponding to the packet loss rate i according to the mapping relationship between the preset packet loss rate and the first channel quality value, and determine the target second channel quality value corresponding to the transmission time i according to the mapping relationship between the preset transmission time and the second channel quality value.
Further, since the number of the relay devices determines the packet loss ratio and the transmission duration probability to a certain extent, a mapping relationship between the preset number of the relay devices and the weight pair may be stored in the electronic device in advance, and then the electronic device may determine, according to the mapping relationship between the preset number of the relay devices and the weight pair, a target weight pair corresponding to the target number of the relay devices, where the weight pair includes a first weight and a second weight corresponding to the packet loss ratio, and a sum of the first weight and the second weight is 1.
Of course, the target weight pair may also correspond to the target first weight and the target second weight, where the target first weight + the target second weight is equal to 1. Furthermore, the electronic device may perform a weighted operation according to the target weight value, the target first channel quality value, and the target second channel quality value to obtain a channel quality value corresponding to the transmission channel i.
The value of the channel quality corresponding to the transmission channel i is equal to the target first weight value + the target second channel quality value
Thus, accurate evaluation of the channel can be realized.

b22, determining a target standby communication channel corresponding to the target position according to a mapping relation between a preset position and a standby communication channel;
and B23, taking the target standby communication channel as the second communication channel.

| mean square error | Adjusting parameters |
| Mean square error 1 | Regulating parameter 1 |
| Mean square error 2 | Regulating parameter 2 |
| Mean square error 3 | Regulating parameter 3 |
