Through big data analysis, judge the intensive degree of the car passenger of every period of time after the night screen arrives, according to the analysis result, lighting system main control board 4 prestores the adjustment time through this mode of ambient brightness control lighting lamp group 13 brightness adjustment according to different seasons, after the predetermined time, mean that ambient brightness is stable and the car passenger of waiting for a day reduces, can be based on according to ambient brightness adjustment, and the passenger quantity of combining the car of waiting for a day carries out comprehensive adjustment.

Taking the passenger number detection unit 10 as an infrared sensor as an example, a method for adjusting the brightness of the lighting lamp set 13 depending on the number of passengers waiting for a bus is described, as shown in the upper flow of the right side of fig. 3, after the passenger number detection unit 10 is started, when the infrared sensor detects that no passenger waits for a bus in a bus stop, the lighting system control main board can reduce the brightness output of the lighting lamp set 13, reduce energy consumption, including reducing the brightness of the ceiling lighting lamp 15 and/or the contour atmosphere lamp 14. After the preset time T1 (the preset time T1 can be determined according to actual conditions and can be changed in the background), the infrared sensor detects whether a passenger waits for the vehicle in the platform again, if the passenger is detected, the lighting system main control board 4 controls the lighting lamp group 13 to improve the brightness output, at this time, the brightness of the ceiling lighting lamp 15 can be only improved, the safety of the passenger waiting for the vehicle is improved, and the brightness of the ceiling lighting lamp 15 and the brightness of the contour atmosphere lamp 14 can also be improved at the same time.

The lighting system main control board 4 can comprehensively adjust the brightness of the whole lighting lamp group 13, especially the ceiling illuminating lamp 15, and also can detect the position of a passenger in the platform by the infrared sensor as described above, and the lighting system main control board 4 only controls and improves the brightness output of the ceiling illuminating lamp 15 of the area where the passenger is located, so as to improve the local brightness of the area where the passenger is located in the platform. The control mode can also be controlled by detecting the data of the passengers of the waiting vehicles through the network camera 12. Or an infrared sensor and the network camera 12 are arranged at the platform at the same time, and the network camera 12 assists the infrared sensor to detect whether the passengers are waiting and the number of the passengers. The network camera 12 and the infrared sensor detect the number of passengers at the same time, and the lighting system main control board 4 and/or the platform centralized controller 6 judge the number and the positions of the passengers in the platform according to a predetermined program, so as to adjust the brightness output of the lighting lamp group 13, including the brightness adjustment and the lighting positions of the lighting lamp group 13. Or the network camera 12 is an auxiliary means, when the infrared sensor has a fault and cannot work normally, the network camera 12 detects whether a passenger waits for a car at the platform, so that the brightness output of the whole platform and/or the brightness of an illuminating lamp in the area where the passenger is located are adjusted, the normal use of the platform illuminating system is ensured from multiple aspects, meanwhile, the main control board 4 of the illuminating system can upload the fault to the platform centralized controller 6, the platform centralized controller 6 communicates with the intelligent trip server 3 after integrating information, and the information is displayed on the management platform 2 and is informed to the administrator 16.

Furthermore, when the infrared sensor is adopted to detect the number of waiting passengers, the brightness output of the whole platform and/or the area where the passengers are located can be respectively adjusted according to the number of the passengers. When the infrared sensor detects that the number of passengers in the platform is less than N, the brightness of the ceiling illumination lamp 15 of the area where the passengers are located can be adjusted only. When the number of passengers is more than N, the brightness of the lighting lamp group 13 of the whole platform is adjusted. For example, when the number of the waiting passengers is less than 5, the brightness of the illuminating lamp in the area where the passengers are located can be adjusted. The brightness mode of the local area and/or the whole platform is adjusted by the number of passengers, and the number of passengers can be determined according to the size of the platform or other specific conditions.

The detection of the number of the passengers is also a cyclic repeated detection after the interval time T2 (which can be set by self or changed in the background), or repeated detection after each bus departure, at the moment, the change of the number of the passengers at the bus is the largest possible, and the detection data is more accurate. Ineffective, frequent human detection is also avoided.

When the brightness of the lighting lamp group 13 is adjusted, the lighting lamp group 13 is controlled to be turned on based on the ambient brightness in the flow shown in fig. 3 from the night fall in time sequence, and then the brightness output is adjusted at any time according to the ambient brightness and the number of passengers waiting for the vehicle. Under the condition that the number of the passengers waiting for the vehicle is large, the lighting lamp set 13 is output in a full-bright state (corresponding to the state of the ambient brightness at that time), the ambient brightness is stable and basically unchanged after the night as time goes on, the number of the passengers waiting for the vehicle is reduced, and the lighting system main control panel 4 adjusts the brightness output of the lighting lamp set 13 according to the increase or decrease of the number of the passengers. On the contrary, in the early morning, when the bus just starts to run, the sky color is darker, but the number of passengers waiting for the bus is small, the brightness of the lighting lamp group is adjusted according to the number of the passengers waiting for the bus, the number of the passengers waiting for the bus is increased along with the fact that the sky light is brighter, and the brightness of the lighting lamp group 13 can be adjusted according to the ambient brightness until the lighting lamp group 13 is turned off.

When the passenger number detection unit 10 does not detect the waiting passengers n times continuously, at this time, n is larger than or equal to 3, the lighting system main control board 4 reduces the brightness output of the lighting lamp group 13, and reduces the energy consumption. When no one waits for a vehicle, the main control panel 4 of the lighting system can reduce the brightness of all the lighting lamps, or only reduce the brightness of the ceiling lighting lamp 15, and the contour atmosphere lamp 14 is reserved for a driver to accurately stop the vehicle, and simultaneously, the information of waiting for the vehicle without the one is transmitted to the driver. In order to avoid the error caused by other similar lighting equipment on the roadside to the stop of a driver, or when the brightness of the contour atmosphere lamp 14 and the ceiling lighting lamp 15 is simultaneously reduced and output, the next step can be carried out, and the brightness of the bus stop lighting lamp group 13 is adjusted according to the bus in-and-out information.

In the present embodiment, when the brightness of the lighting lamp set 13 is adjusted, the brightness output of the lighting lamp set 13 may be adjusted based on the ambient brightness, the number of passengers, and the positions, respectively, as shown in the logic of fig. 3, and in practical applications, the brightness of the lighting lamp set 13 may be adjusted by the method described above based on only one of the parameters.

Or a simpler control mode is adopted, and due to the shed-shaped structure of the bus station, when the curtain falls down at night, the internal environment brightness of the bus station is smaller than the external environment brightness, namely, the interior of the bus station is relatively dark. When the brightness value of the internal environment of the bus stop is smaller than the brightness value of the lighting lamp group 13, the lighting system main control board 4 controls the lighting lamp group 13 to be turned on at the maximum brightness value which can be turned on, along with the reduction of the brightness value of the internal environment of the bus stop, the lighting system main control board 4 controls the lighting brightness of the lighting lamp group 13 to be gradually reduced until the minimum brightness value which can be turned on by the lighting lamp group 13 is kept, and on the contrary, along with the increase of the brightness value of the internal environment of the bus stop, the lighting system main control board 4 controls the lighting brightness of the lighting lamp group 13 to be gradually improved until the maximum brightness value which can be turned on by the lighting lamp group 13 is kept; when the brightness value of the internal environment of the bus stop is greater than the brightness value of the lighting lamp set 13, the lighting system main control board 4 controls the lighting lamp set 13 to be turned off.

In another embodiment of the present invention, when the brightness value of the external environment at the bus stop is less than the brightness value of the turning-on contour atmosphere lamp 14, the lighting system main control board 4 controls the turning-on of the contour atmosphere lamp 14 at the maximum brightness value that can be turned on, and as the brightness value of the external environment at the bus stop decreases, the lighting system main control board 4 controls the lighting brightness of the contour atmosphere lamp 14 to gradually decrease until the lighting brightness is maintained at the minimum brightness value that the contour atmosphere lamp 14 can be turned on, whereas as the brightness value of the external environment at the bus stop increases, the lighting brightness of the lighting system main control board 4 controls the lighting brightness of the contour atmosphere lamp 14 to gradually increase until the lighting brightness is maintained at the maximum brightness value that the contour atmosphere lamp 14 can be turned on; when the brightness value of the external environment at the bus stop is greater than the brightness value of the on-contour atmosphere lamp 14, the lighting system main control board 4 controls the lighting of the contour atmosphere lamp 14 to be off. When the brightness value of the internal environment of the bus stop is smaller than the brightness value of the ceiling illuminating lamp 15, the lighting system main control board 4 controls the ceiling illuminating lamp 15 to be turned on at the maximum brightness value which can be turned on, along with the reduction of the brightness value of the internal environment of the bus stop, the lighting system main control board 4 controls the lighting brightness of the ceiling illuminating lamp 15 to be gradually reduced until the minimum brightness value which can be turned on by the ceiling illuminating lamp 15 is kept, along with the increase of the brightness value of the internal environment of the bus stop, the lighting brightness of the lighting system main control board 4 controls the ceiling illuminating lamp 15 to be gradually improved until the maximum brightness value which can be turned on by the ceiling illuminating lamp 15 is kept; when the brightness value of the internal environment of the bus stop is greater than the brightness value of the lighting lamp 15 on the ceiling, the lighting system main control board 4 controls the lighting lamp 15 on the ceiling to be turned off.

S2: as described above, as time goes on, after night, the ambient brightness is stable, the brightness data is basically unchanged, the number of waiting passengers is gradually reduced, no waiting passenger is detected for a plurality of times at some stations, and at this time, the brightness output of the lighting lamp group 13 can be controlled according to the information of the bus station entering and exiting.

Each bus can be respectively connected with a station to be arrived through a bus running state judging unit 5, the bus running state judging unit 5 provides station entering and exiting information for the lighting system main control board 4, and when the bus meets a preset station entering condition, the lighting system main control board 4 controls the lighting lamp set to adjust the brightness according to the detection information.

When the lighting system main control board 4 receives the coming bus stop and the relevant operation parameters, the brightness output of the lighting lamp group 13 is controlled according to the preset program. The relevant operation parameters of the bus include, but are not limited to, the distance of the bus from the bus stop and the expected arrival time.

Further, as shown in the flow of the lower right part of fig. 3, the lighting system main control board 4 can preset, according to the number of passengers, that when the predicted arrival time of the bus is less than or equal to 30s, the brightness of the lighting lamp set 13 at the whole station is increased, and from the condition that the brightness is low when no passenger waits or the local brightness is large when the number of passengers is small, the brightness is increased to the condition that all lighting lamps at the total station are output in the state that passengers wait for the bus and the current ambient brightness is met, and an accurate stop position is provided for the driver of the bus at night. Furthermore, the brightness of the bus station can be adjusted according to the distance between the bus and the station. The specific arrival time and distance data can be automatically set, the setting of the time and the distance can be dynamically adjusted according to the running time of the bus, for example, during the peak period of commuting and off-duty, under the condition of small running speed of the bus, relatively small distance data and large arrival time are set, and at night when the number of waiting persons is small or the running speed of the bus is high, the distance data is properly improved and the arrival time is reduced

When the main control board 4 and/or the station integrated controller 6 of the lighting system receive the bus arrival parameters transmitted by the bus running state judgment unit 5, the brightness output of the lighting unit 3 is adjusted, and under the condition of low brightness, the brightness of all lighting lamps of the whole station is improved, so that the lighting lamp group 13 outputs the brightness with more passengers or the brightness according with the current environment brightness. Certainly, under the condition that the bus or the surrounding environment outside the bus is single and the misjudgment of the driver is not caused, and when no passenger waits for the bus and the overall brightness of the lighting lamp group 13 is low, the main control board of the lighting system can only improve the brightness of the contour atmosphere lamp 14 according to the bus arrival information, and the contour atmosphere lamp 14 provides the bus stop information for the driver.

The lighting system main control board 4 and/or the station integrated controller 6 have a rectification function, and if the bus does not enter the station within a preset time or does not receive the station entering information after multiple detections, the lighting system main control board 4 and/or the station integrated controller 6 maintain the brightness of the lighting lamp group 13.

S3: after the lighting system main control board 4 and/or the station integrated controller 6 receive the information of entering the station of the bus running state judgment unit 5, during the stop of the bus, the lighting system main control board 4 and/or the station integrated controller 6 maintain the brightness of the lighting lamp group 13, after the information of leaving the station of the bus is received, the detection of the passenger and/or the ambient brightness is carried out again according to a preset program, the brightness of the lighting lamp group 13 is adjusted, namely, the bus leaves the station, and then the bus enters the automatic adjustment mode of the lighting lamp group 13 again. The bus departure information includes, but is not limited to, time after the bus departs, departure distance, and the like. And the platform illumination enters an automatic adjustment mode according to the ambient brightness and the number of passengers through time control, for example, after 3 minutes (the time can be set by self and can be changed in a background) is received when a bus is about to enter the station.

It should be noted that, when the brightness value of the external environment at the bus stop is smaller than the brightness value of the power supply of the lighting lamp group 13, the lighting system main control board 4 controls the power supply of the lighting lamp group 13 to be turned on, otherwise, the lighting system main control board 4 controls the power supply of the lighting lamp group 13 to be turned off or to be kept in a turned-off state. The existing bus station is generally provided with a large billboard on a back board of the station, and the large billboard provides illumination for the whole station by lighting an illuminating lamp at the billboard, so that a ceiling illuminating lamp 15 and a contour atmosphere lamp 14 are not arranged respectively, and when intelligent illumination regulation and control are carried out, the adjustment and control of the illumination brightness of the whole station are realized by adjusting the brightness of the billboard.

In the invention, the ceiling illuminating lamp 15 is a color temperature lamp, the lighting system main control board 4 can also adjust the color temperature of the ceiling illuminating lamp 15 according to the environment temperature collected by the temperature sensor 11, and the temperature condition can be inquired and modified through the management platform 2. As shown in fig. 5, when the outside temperature is less than or equal to 15 ℃, the ceiling illuminating lamp 15 outputs warm light with a color temperature of less than or equal to 3000K; when the external temperature is less than or equal to 25 ℃ and 15 ℃, the ceiling illuminating lamp 15 outputs 3000K to 4000K natural light; when the outside temperature is more than 25 ℃, the ceiling illuminating lamp 15 outputs cold light higher than 6000K, and provides more comfortable light illumination for passengers according to different outside temperatures. In the present embodiment, the warm light color temperature is 3000K, the natural light color temperature is 4000K, and the cold light color temperature is 6000K.

In summary, compared with the prior art, the control method of the intelligent lighting system for the bus stop provided by the invention can be used for controlling the brightness adjustment of the lighting system in cooperation with the condition that the bus enters or exits the bus, and when the bus meets the condition of entering the bus, the lighting lamp group is controlled by the main control panel of the lighting system to improve the lighting brightness, so that the lighting requirements of a driver and passengers when the bus enters the bus are met; when the bus meets the outbound condition, the lighting lamp set restores the automatic adjusting mode; in the deep liquid or early morning, when no one waits for a bus, the illumination brightness of the platform is reduced, and the brightness is adjusted by matching with the information of the bus entering and leaving the platform, so that the energy consumption is effectively reduced; under the automatic regulation mode, the main control panel of the lighting system can control part or all of the lighting lamp sets to regulate the brightness according to the ambient brightness and whether passengers wait and/or the number of passengers, so that the problem of power consumption caused by the unified regulation of the brightness of the lighting lamp sets when no passengers or a small number of passengers wait at a platform is solved.

Similar solutions can be derived as described above in connection with the given solution content. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the invention are still within the scope of the technical solution of the invention.
