The analysis main control module 100 is also used to receive input control signals.

[0025] The plurality of lighting modules 600 are used to adjust the lighting based on the adjustment instructions of the connected passenger compartment sub-control modules 500.

[0026] By setting up a timing positioning module 200, the present invention can collect the current time according to the sunrise and sunset conditions of the current time zone to complete the conversion of different scene lighting modes according to seasons, times, and time zones; according to the current positioning, after switching the time zone, the present invention can complete the conversion of different scene lighting modes according to seasons and times according to the current time zone, and automatically adjust the lighting mode.

[0027] The analysis main control module 100 has various built-in lighting modes.

[0028] The lighting modules 600 include a lighting power supply module 601 and lighting fixtures 602; the lighting power supply module 601 is connected to the passenger compartment sub-control module 500, and the lighting fixtures 602 are connected to the lighting power supply module 601. The lighting fixtures 602 are lighting execution terminals of each compartment, and execute various lighting modes with different color temperatures and lighting emitted by the passenger compartment sub-control module 500.

[0029] The present invention further comprises a plurality of switch modules 700 , and the image acquisition module 300 is connected to the analysis main control module 100 via the connected switch modules 700 . The switch modules 700 are used to send the image data acquired by the image acquisition module 300 to the analysis main control module 100 .

[0030] In the embodiment of the present invention, the timing and positioning module 200 includes a Beidou timing and positioning module, and the Beidou timing and positioning module includes an external Beidou antenna. The Beidou antenna is used to collect time information.

[0031] In an embodiment of the present invention, the lighting modes include a normal mode, a small passenger flow environmental protection mode, a normal maintenance mode and a high brightness maintenance mode.

[0032] In a specific example, the analysis of the lighting mode of the main control module 100 includes: Taking Beijing, China as the benchmark, the color temperature changes with the seasons as follows: In spring (March-May), the color temperature is set between 4000k-5500k. During the day (7:00 am-7:00 pm), the color temperature is between 4500k-5500k. At night (7:00 pm-7:00 am), the color temperature is between 4000k-5000k.

[0033] In summer (June-August), the color temperature is set between 5000k-6500k. During the day (6:00 am-8:00 pm), the color temperature is between 5500k-6500k. At night (8:00 pm-6:00 am), the color temperature is between 5000k-6000k.

[0034] In autumn (September-November), the color temperature is set between 4000k-5500k. During the day (7:00 am-7:00 pm), the color temperature is between 4500k-5500k. At night (7:00 pm-7:00 am), the color temperature is between 4000k-5000k.

[0035] In winter (November-February), the color temperature is between 2700k-4500k. During the day (8:00 am-6:00 pm), the color temperature is between 3500k-4500k. At night (6:00 pm-8:00 am), the color temperature is between 2700k-4000k.

[0036] Specifically, when the external Beidou antenna collects location information (longitude and latitude), compensation adjustment is made to the lighting mode change time.

[0037] Taking the East 8 district where Beijing is located as the reference position, when the timing positioning module confirms the East n district, the time point of all lighting changes in 1 becomes t+8-n. For example, in the summer in the East 6 district In summer (June-August), the color temperature is between 5000k-6500k. During the day (8:00 am-10:00 pm), the color temperature is between 5500k-6500k. At night (10:00 pm-8:00 am), the color temperature is between 5000k-6000k.

[0038] In an embodiment of the present invention, the small passenger flow environmental protection mode includes: When the vehicle is under high pressure, and the number of passengers counted by image acquisition is less than 80-100, it enters the small passenger flow environmental protection mode, which includes: If there are 10 or fewer people in a single carriage (including 10 people), the illumination of this carriage will be reduced to 80% lighting mode; If there is no one in a carriage, the illumination of this carriage will be reduced to 50% lighting mode; If 1 to 10 people enter a single carriage, the illumination of this carriage will be restored to 80% lighting mode; If more than 10 people are detected entering a single carriage, the illumination in this carriage will be restored to 100% lighting mode.

[0039] In an embodiment of the present invention, the common maintenance mode includes: If there is no one in a single carriage, the illumination of this carriage is in 30% lighting mode; If there are more than 1 person in a single compartment (including 1 person), the illumination of this compartment is 80% lighting mode. This mode is automatically turned on when there is no high voltage in the vehicle.

[0040] In an embodiment of the present invention, the maintenance mode includes: When the vehicle has no high voltage, the system enters the maintenance mode by default. When there is a need for operations with higher brightness, the inspector can change the system to high brightness maintenance mode through the human-machine interface. If there is no one in a single carriage, the illumination of this carriage is 30% lighting mode; If there is more than one person (including one person) in a single carriage, the illumination of this carriage is 100% lighting mode.

[0041] In the embodiment of the present invention, the lighting mode further includes: the lighting time is counted for the high-power operation time of each lamp.

[0042] In all lighting modes, the image acquisition module is used to collect the lighting duration of each lamp. The replacement status of each lighting fixture terminal is set. The lighting status of the car lights is judged by comparing the position in the image and the brightness of the lamp at that position with other things in the environment, and the lighting duration of each position is recorded separately. The lighting duration of the lamp at that position is accumulated every time the lamp at that position is turned off.

[0043] If the luminaire exceeds 100 lux at 800m from the ground of the passenger compartment, it is considered to be lit. If it is 50lux-100lux, the lighting time of the luminaire is not calculated, and only the lighting status is recorded.

[0044] In the embodiment of the present invention, the analysis main control module 100 is also used to obtain the lighting duration and lighting times of each lighting fixture 602 based on the image acquisition data, and determine whether the lighting duration of the lighting fixture 602 exceeds the duration threshold and the lighting times exceeds the times threshold based on the pre-set duration threshold and times threshold, and if any one of them exceeds, an update instruction is issued. In this way, the lighting fixture 602 can be accurately updated.

[0045] Specifically, the analysis main control module 100 determines the lighting status of the vehicle lights by comparing the position in the image and the brightness of the lamp at that position with other things in the environment, and records the lighting duration of each position separately, and accumulates the lighting duration of the lamp each time the lamp at that position goes out. The lamp is considered to be lit if it exceeds 100 lux at 800mm from the floor of the passenger compartment. When it is 50lux-100lux, the lighting duration of the lamp is not calculated, and only the lighting status is recorded.

[0046] The analysis main control module 100 determines the lighting status of the car lights by comparing the position in the image and the brightness of the lamp in that position with other things in the environment, and records the number of lighting times for each position. Each time the lamp at that position goes out, the number of lighting times for that lamp is accumulated by 1. When the lamp changes from an off state (0-30lux) to more than 50lux at a distance of 800mm from the floor of the passenger compartment, it is considered to be lit. When the light level drops from more than 80lux to less than 50lux in the lit state, it is considered to be turned off. One lighting or extinguishing switch count is accumulated by 1. All non-conventional lighting (low illumination) in emergency situations should be calculated. When there are more than 1 (including 1) lamps lit in the picture, it is considered to be lit, and when all lamps in the picture are off, they are considered to be off. The action time of lighting or extinguishing is recorded in groups according to the power supply group of the power module.

[0047] Specifically, when the lighting life of the lamp reaches 4500 hours to 5000 hours, each time the system is powered on, a reminder will be given that the lamp is about to reach its service life limit and a replacement reminder will be given.

[0048] When the power module lights up 80,000 times, a prompt appears each time the system is powered on, indicating that the power module is about to reach the end of its service life and needs to be replaced.

[0049] If there is no fault information in item 8 and no replacement suggestions in the first two items in the past five days, the system will prompt when it is powered on that the passenger compartment lighting is currently in maintenance-free status.

[0050] The analysis main control module 100 is also used to determine whether the lighting fixture 602 is damaged based on the image data, and send a damage signal if it is damaged.

[0051] Specifically, when receiving a light-on command, the image acquisition module 300 detects that the lamp is not executing according to the current mode, and stores the fault information according to "time + current lighting mode + fault prediction" and reports it to the driver through the human-computer interaction interface of the vehicle TCMS system.

[0052] Fault 1: The lamp is damaged as a whole It was monitored that the control unit and the power module had power, the lighting was in normal lighting or maintenance lighting mode, the power module did not feedback fault information, and the image acquisition showed that one or several lamps were not lit (the lamp was below 50 lux at 800m from the passenger compartment floor), judging that one or several lamps were damaged as a whole.

[0053] Fault 2: The lamps do not match It is monitored that the control unit and the power module have power, the lighting is in normal lighting or maintenance lighting mode, the power module does not feedback fault information, and the image captures one or several lamps. The brightness difference in the current mode is large (the difference is more than 30 lux when the lamp is 800m away from the passenger compartment floor). It is judged that one or several lamps do not match the current passenger compartment lamps.

[0054] Fault 3: Part of the lamp is damaged It was monitored that the control unit and the power module had power. The lighting was in normal lighting or maintenance lighting mode. The power module did not feedback fault information. The image acquisition showed that the lamp was lit, but there was an obvious shadow over 20% of the area within the lighting range. It was determined that some circuit boards of the lamp were damaged.

[0055] The analysis main control module 100 is also used to count the cumulative lighting time of the lighting fixture 602 under 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. If so, a power compensation instruction is issued to the passenger room sub-control module 500.

[0056] The passenger compartment sub-control module 500 sends a power compensation signal to the lighting power supply module 601 based on the power compensation instruction.

[0057] The lighting power supply module 601 increases the power of the lighting fixture 602 based on the power compensation signal.

[0058] Specifically, power compensation mode 1 When the cumulative lighting life of more than half of the lamps in the passenger room reaches 20,000 hours, the master control adjusts the output command, and the original full lighting is adjusted to 115% of the original illumination, 230W-345W. All ordinary lighting and maintenance modes use 115% illumination as the full illumination, and adjust all lighting outputs.

[0059] Power Compensation Mode 2 When the cumulative lighting life of more than half of the lamps in the passenger room reaches 30,000 hours, the master control adjusts the output command, and the original full lighting is adjusted to 120% of the original illumination, 240W-360W. All ordinary lighting and maintenance modes use 120% illumination as the full illumination, and adjust all lighting outputs.

[0060] Power Compensation Mode 3 When the cumulative lighting life of more than half of the lamps in the passenger room reaches 40,000 hours, the master control adjusts the output command, and the original full lighting is adjusted to 125% of the original illumination, 250W-375W. All ordinary lighting and maintenance modes use 125% illumination as the full illumination, and adjust all lighting outputs.
