摘要： Inside a railway train, a wall or door is set between the non-restricted carriage and the restricted carriage for separation, including the instruction system, execution system and server. The said instruction system comprises a passenger counting unit, a gate instruction unit and a storage unit; the said execution system comprises a gate control unit arranged on a riding area computer at the next station; and the passenger counting unit transmits the total number of passengers that have entered the restricted carriage to the gate instruction unit. The gate instruction unit obtains the gate instruction based on the total number of passengers that have entered the restricted carriage. The gate control unit of the riding area computer at the next station also executes the gate instruction, so as to control the number of passengers that have entered the riding area within the maximum number of passengers.
