when the timing duration of the verification timer reaches a preset value, storing the weather sensing data corresponding to the verification timer in a dump database as lost sequence data, resetting the verification timer and emptying the corresponding weather sensing data;
forwarding or sending the lost sequence data through the wireless communication network, and receiving and forwarding the returned verification information, wherein a plurality of verifiers corresponding to the coding marks are arranged in the forwarding database, the verifiers are used for responding the returned verification information and clearing the corresponding lost sequence data, and the returned verification information comprises an identification tag.
7. The sensor-based weather detection method according to claim 6, further including a time synchronization routine, said time synchronization routine including the steps of:
receiving synchronous request information and sending the synchronous request information at a preset synchronous time interval, wherein the synchronous request information comprises a sending time node and a period duration from the sending time node to a receiving time node;
and calculating and generating signal transmission delay according to the period duration and the synchronization time interval, so that time axes at two ends of the wireless local area network are synchronized based on the signal transmission delay and the sending time node.
8. The weather detection method according to claim 7, wherein the number of the sensors is multiple groups, each group of the sensors has the corresponding backhaul library and the corresponding transfer library, a plurality of adjacent backhaul libraries are mutually connected for establishing a multi-channel data transmission network, the backhaul libraries are further configured to execute a backhaul processing procedure, and the backhaul processing procedure includes:
after the step of forwarding the lost sequence data is executed by the forwarding library, enabling a return forwarding program for receiving and forwarding the return verification information;
and after the step of sending the lost sequence data is executed by the transfer library, enabling the verifier to respond the returned verification information and clear the corresponding lost sequence data.
