Claim 6:
7. The health protection method for passengers on a train in a polluted indoor environment according to claim 6, wherein a number of neurons in each layer of the stacked long short-term memory network model is obtained by optimization of a firefly algorithm, specifically comprising the following steps:
1) Determine a fitness function;
2) Perform initialization setting on the firefly algorithm;
3) Arrange and archive all fireflies by fitness;
4) Screen out an optimal firefly from a group as an individual leader; and
5) determine a search frequency:
if the search frequency meets a requirement, finish the firefly algorithm and output an optimal solution to determine a number of optimal neurons of the stacked long short-term memory network model; and
if the search frequency does not meet the requirement, repeat the steps 3)-5) until the search frequency meets the requirement.
