S2, setting the maximum initial power level, and enabling a master station and a slave station to work at an initial working frequency fc; at the beginning of the start-up, the power level is set to be maximum in order to ensure that the communication can be normal.
S3, the master station polls the slave station in a period T, the slave station receives a polling instruction of the master station and gives a response, and the master station indicates that a communication network is established after receiving the response.
If the main station receives the response, the main station indicates that the communication network is established;
if the master station does not receive the response of the slave station, the master station always polls and waits for the response;
s4, after receiving the response, the master station inquires the RSSI value of the slave station,
the query is successful, and the slave station reports the stored RSSI value to the master station;
the inquiry is unsuccessful, and the inquiry is continued;
s5, calculating an optimal frequency;
s6, transmitting the optimal frequency to the slave station;
