In the embodiment of the invention, when a train is in a train operation passenger-carrying disinfection mode, a self-resetting knob switch is positioned at a normal gear, a vehicle network controller (CCU/LCU) collects a zero-speed instruction from a brake system (BCU/ATC), judges whether the zero-speed instruction is true, determines that the train is static when the zero-speed instruction is true, and sends a closing instruction to a far ultraviolet controller to close the far ultraviolet lamp in order to save energy of the far ultraviolet lamp and prolong the service life of the far ultraviolet lamp; when the zero-speed instruction is not true, the train is determined to be running, the vehicle network controller sends a working instruction to the far ultraviolet controller, the far ultraviolet lamp starts disinfection and sterilization according to the received working instruction, meanwhile, the vehicle network controller starts timing, when the preset first timing threshold value is reached by timing, or the received zero-speed instruction is true, the vehicle network controller sends a closing instruction to the far ultraviolet controller, and the far ultraviolet lamp finishes disinfection and sterilization work.
In the embodiment of the invention, when the train is returned to the garage after operation and is in a static train maintenance disinfection mode, the self-reset knob switch is switched to the maintenance gear, the vehicle network controller sends a lighting disinfection command to the far ultraviolet lamp controller after acquiring that the self-reset knob switch is in the maintenance gear, the far ultraviolet lamp starts disinfection work, the vehicle network controller starts timing, when the preset second timing threshold value is reached, the vehicle network controller sends a closing command to the far ultraviolet lamp controller, the far ultraviolet lamp stops working, and the maintenance disinfection is finished.
In the embodiment of the invention, the self-reset knob switch is defaulted to be a normal gear, the vehicle network controller utilizes a zero-speed instruction provided by a brake system BCU/ATC, when the speed of a train is lower than 0.5km/h, a zero-speed instruction signal output by the brake system BCU/ATC is true, a start-stop control instruction is output according to the zero-speed instruction and a sterilization mode, the self-reset knob switch has timing calculation capabilities of different sterilization modes, the far ultraviolet controller receives a control instruction sent by the vehicle network controller and performs on-off control on a far ultraviolet lamp, and the far ultraviolet lamp is installed on a top plate in a carriage of a passenger room of the train. The first timing threshold and the second timing threshold can be set in a gradient mode according to the space of a passenger compartment, for example, the first timing threshold and the second timing threshold can be accurately set according to the radiation irradiation distance-time-sterilization intensity of the far ultraviolet lamp so as to ensure that 99.7% of viruses and bacteria are sterilized in the far ultraviolet radiation space, so that corresponding sterilization schemes are formulated according to different sterilization modes, and meanwhile, corresponding timing control can be performed according to different sterilization modes, so that the service time of the far ultraviolet lamp is prolonged, and the early-stage investment and the later-stage maintenance cost are reduced.
In the embodiment of the invention, as an optional embodiment, the far ultraviolet lamp is a far ultraviolet lamp with the wavelength of 222nm, and the far ultraviolet with the wavelength only acts on the surface layer of an object, so that pathogens in the air in the respiratory region around passengers can be killed, new coronavirus and bacteria in the compartment space of a passenger room can be effectively killed, human and machine coexistence can be realized, meanwhile, radiation injury to the passengers is not caused, people-borne transmission and droplet transmission of the new coronavirus in the operation process of a train are prevented, the spreading of epidemic situations is avoided, and the riding safety of the passengers is ensured.
In the embodiment of the invention, as an alternative embodiment, the far ultraviolet lamp is arranged on a ceiling board in a passenger compartment, for example, the periphery of a top layer installation illuminating lamp or arranged in the illuminating lamp. As another alternative, the extreme ultraviolet lamps are uniformly disposed on the ceiling in the passenger compartment, and are capable of emitting extreme ultraviolet light from the ceiling to the floor in the passenger compartment.
In the embodiment of the invention, passengers flow in the passenger compartment during the operation of the train, and the virus propagation risk mainly lies in the flowing contact of the passengers, so that when the far ultraviolet lamp is used for killing the virus, the distance between the passengers standing or sitting on the seat and the far ultraviolet lamp is shorter, so that the power density of the far ultraviolet lamp irradiating in the range is higher, and the shorter irradiation time can meet the requirements of disinfection and sterilization of the passengers in the passenger compartment. During maintenance, viruses are mainly left on the surfaces of equipment, the floor surface and the peripheral surface of the passenger compartment, so that when the far ultraviolet lamp is used for killing the viruses, the distance between the surfaces of the floor and the like in the range and the far ultraviolet lamp is longer, the power density of the far ultraviolet lamp irradiating the range is lower, and the long time is required for irradiating the surfaces in the passenger compartment, so that the requirements for disinfection and sterilization of the surfaces in the passenger compartment can be met. Therefore, as an optional embodiment, the irradiation time of the far ultraviolet lamp in the maintenance period is longer than the irradiation time of the far ultraviolet lamp in the operation period, that is, the first timing threshold is smaller than the second timing threshold, so that the service time of the far ultraviolet lamp can be prolonged as much as possible, and the early-stage investment and the later-stage maintenance cost of the far ultraviolet lamp are reduced.
In this embodiment, as an optional embodiment, the vehicle network controller is further configured to, after timing to a preset first timing threshold and sending a close instruction to the far ultraviolet controller, perform the killing mode of the collection mode control switch according to a preset collection period at intervals of a preset discontinuous period, so as to avoid frequent start of the far ultraviolet lamp.

and the second camera is arranged at the tail of the train, outputs an operation scene instruction to the vehicle network controller when the fact that the shot image contains the maintenance scene characteristic and the shot image is farther away from the maintenance scene characteristic is determined, and switches the gear of the mode control switch into a normal gear after the vehicle network controller receives the operation scene instruction.
