the train channel disinfection method comprises the following steps:
the disinfection control device starts a disinfection identification program;
the disinfectant detection device detects the concentration of the disinfectant in the train carriage according to the disinfection identification program;
and the disinfection device analyzes whether continuous disinfection is needed according to the concentration of the disinfection solution, and if so, sets the spraying quantity, the concentration and the time of the solution to be sprayed according to the concentration of the disinfection solution to disinfect the train carriage.
7. The method of disinfecting a train passageway according to claim 6, wherein the step of analyzing whether the disinfection device needs to continue the disinfection according to the concentration of the disinfection solution comprises:
if the concentration of the disinfectant is greater than or equal to a disinfectant concentration threshold, the disinfectant is not disinfected by the disinfectant device;
and if the concentration of the disinfectant is smaller than the threshold value of the concentration of the disinfectant, the disinfecting device performs disinfecting treatment.
8. The method of disinfecting a train pathway according to claim 7, wherein said disinfecting means performs a disinfecting process if said disinfecting liquid concentration is less than said disinfecting liquid concentration threshold value, comprising:
calculating the concentration of the disinfectant solution in the current carriage according to the concentration of the disinfectant and the humidity of the carriage;
judging whether the concentration of the disinfectant solution is greater than the minimum concentration of the disinfectant solution for effective disinfection;
if the concentration of the disinfectant solution is greater than or equal to the minimum concentration, setting the concentration of the disinfectant solution to be sprayed as the concentration of the disinfectant solution, and calculating the spraying amount and time of the disinfectant to be sprayed according to the concentration of the disinfectant solution;
if the concentration of the disinfectant solution is smaller than the minimum concentration, setting a value larger than the minimum concentration as the concentration of the disinfectant solution to be sprayed, and calculating the spraying quantity and time of the disinfectant solution to be sprayed according to the set concentration of the disinfectant solution to be sprayed.
