[0070] In the embodiment of the present application, the small passenger flow environmental protection mode comprises:

[0071] When the vehicle has high pressure, when the image acquisition statistics of the whole vehicle passengers is about 80-100 people or less, the small passenger flow environmental protection mode is entered, which specifically comprises:

[0072] Single car less than or equal to 10 people (including 10 people), the illumination of the car is reduced to 80% illumination mode;

[0076] In the embodiment of the present application, the general maintenance mode comprises:

[0077] Single car has no one, the illumination of the car is 30% illumination mode;

[0078] Single car has more than 1 person (including 1 person), the illumination of the car is 80% illumination mode. Wherein this mode is automatically started when the vehicle has no high pressure.

[0079] In the embodiment of the present application, the maintenance mode comprises:

[0080] When the vehicle has no high pressure, the system defaults to enter the maintenance mode, when there is a high brightness operation demand, the maintainer can change the system to high-brightness maintenance mode through the man-machine interface. Single car has no one, the illumination of the car is 30% illumination mode;

[0082] In the embodiment of the present application, the illumination mode further comprises: the lighting duration is counted for the high-power operation duration of each lamp.

[0083] In all illumination modes, the lighting duration of each lamp is collected through the image acquisition module. The replacement condition of each illumination lamp terminal is set. The lighting condition of the car lamp is judged through the position in the image and the brightness of the lamp in the position compared with other things in the environment, and the lighting duration of each position is recorded respectively. After the lamp in the position is extinguished, the duration of the lamp is accumulated.

[0084] The light fixture is considered to be lit when the light intensity at a distance of 800 mm from the passenger room floor exceeds 100 lux. When the light intensity is between 50 lux and 100 lux, the light-on duration of the light fixture is not calculated, and only the light-on state is recorded.

[0085] In the embodiment of the present application, the analysis master module 100 is further configured to acquire the light-on duration and the light-on times of each lighting fixture 602 based on the image acquisition data, and determine whether the light-on duration of the lighting fixture 602 exceeds the duration threshold and whether the light-on times exceed the times threshold based on the pre-prepared duration threshold and times threshold. If either of the two exceeds, the update instruction is issued. In this way, the lighting fixture 602 can be accurately updated.

[0086] Specifically, the analysis master module 100 determines the light-on state of the vehicle light based on the position in the image and the contrast between the brightness of the light fixture in the position and other objects in the environment, and records the light-on duration of each position respectively. The light fixture is considered to be lit when the light intensity at a distance of 800 mm from the passenger room floor exceeds 100 lux. When the light intensity is between 50 lux and 100 lux, the light-on duration of the light fixture is not calculated, and only the light-on state is recorded.

[0087] The analysis master module 100 determines the light-on state of the vehicle light based on the position in the image and the contrast between the brightness of the light fixture in the position and other objects in the environment, and records the light-on times of each position respectively. The light-on times of the light fixture are added by one each time the light fixture in the position is extinguished. The light fixture is considered to be lit when the light intensity at a distance of 800 mm from the passenger room floor changes from the extinguished state (0-30 lux) to more than 50 lux. When the light intensity decreases from the light-on state (more than 80 lux) to less than 50 lux, the light fixture is considered to be extinguished, and the switching times are added by one. The light-on times of all emergency lighting (low light intensity) in all abnormal situations should be calculated. When more than one (including one) light fixtures in the image are lit, it is considered to be lit. When all the light fixtures in the image are extinguished, it is considered to be extinguished. The light-on or extinguishing action time is recorded in groups according to the power supply module.

[0088] Specifically, when the light fixture light-on life reaches 4500 hours-5000 hours, the system prompts the light fixture life to be close to the limit each time the system is powered on, and the replacement prompt.

[0089] When the light-on times of the power supply module reach 80000 times, the system prompts the power supply module life to be close to the limit each time the system is powered on, and the replacement prompt.

[0090] When there is no fault information of item 8 and the replacement suggestion of the previous two items for nearly 5 days, the system prompts the passenger room lighting to be in a maintenance-free state.

[0091] The analysis master module 100 is also used to determine whether the lighting lamp 602 is damaged based on the image data, and issue a damage signal if damaged.

[0092] Specifically, when receiving a light-on instruction, the image acquisition module 300 acquires that the lamp does not execute according to the current mode, stores the fault information according to “time+current lighting mode+fault prediction”, and reports the driver through the human-computer interaction interface of the vehicle TCMS system.

[0093] Fault 1: The whole lamp is damaged

[0094] The control unit and the power module are monitored to have electricity, the lighting is in the normal lighting or maintenance lighting mode, the power module does not feedback fault information, and the image acquisition module acquires that one or more lamps are not lit (the light is below 50 lux at 800 m from the passenger room floor), and it is determined that one or more lamps are damaged as a whole.

[0095] Fault 2: The lamp does not match

[0096] The control unit and the power module are monitored to have electricity, the lighting is in the normal lighting or maintenance lighting mode, the power module does not feedback fault information, and the image acquisition module acquires that one or more lamps have a large brightness difference (the difference is more than 30 lux at 800 m from the passenger room floor) in the current mode, and it is determined that one or more lamps do not match the current passenger room lamps.

[0097] Fault 3: The lamp is partially damaged

[0098] The control unit and the power module are monitored to have electricity, the lighting is in the normal lighting or maintenance lighting mode, the power module does not feedback fault information, and the image acquisition module acquires that the lamp is lit, but more than 20% of the area in the lighting range has obvious shadow, and it is determined that the lamp has partial circuit board damage.

[0099] The analysis master module 100 is also used to statistically determine the cumulative lighting time of the lighting lamp 602 under the maximum illumination based on the image data, and determine whether the cumulative lighting time exceeds the light decay time of the lighting power supply module 601, and if so, issue a power compensation instruction to the passenger room sub-control module 500.

[0100] The passenger room sub-control module 500 issues a power compensation signal to the lighting power supply module 601 based on the power compensation instruction.

[0101] The lighting power supply module 601 increases the power of the lighting lamp 602 based on the power compensation signal.

[0102] Specifically, the power compensation mode 1

[0103] When the cumulative lighting life of more than half of the lamps in the passenger compartment reaches 20000 hours, the main control adjusts the output command, the original full lighting is adjusted to 115% of the original illuminance, 230W-345W, all ordinary lighting and maintenance mode is 115% of the illuminance as the full illuminance, and all lighting output is adjusted.
