Specific embodiment
Specific embodiment 1: illustrating present embodiment below with reference to Fig. 1 and Fig. 3.Present embodiment includes: bracket2 and signal lamp 4, the signal lamp 4 is arranged on bracket 2, it further includes warning lamp 8, haze detection device 9 and pedestrian detection dressIt sets, the pedestrian detection device is used to detect the mist in air for detecting pavement pedestrian contact signal, haze detection device 9The output end of haze grading index, the output end of the haze detection device 9 and pedestrian detection device two with controller 5 respectivelyInput terminal connection, two signal output ends of the controller 5 letter with the signal input part of signal lamp 4 and warning lamp 8 respectivelyThe connection of number input terminal, warning lamp 8 are mounted on the bracket 2 by signal lamp.
Working principle: change program containing traffic light cycles in signal lamp 4, it is signal lamp that traffic light cycles, which change program,The traffic guidance transformation period of red, yellow, and green lamp, signal lamp 4 change program work by traffic light cycles；
Haze detection device 9 is used to detect haze grading index in air, haze grade be respectively from low to high yellow,It is orange and red.Above-mentioned grade uses visibility and air humidity as the index for dividing haze grade.Reach yellowness ratings withOn then driver need careful driving.And the standard of yellowness ratings are as follows: visibility is less than 3000 meters and relative humidity is less than80% haze；Or visibility is less than 3000 meters and relative humidity is more than or equal to 80%, PM2.5 concentration and is greater than 115 micrograms/cubic meterAnd it is less than or equal to 150 micrograms/cubic meter；Or visibility is less than 5000m, PM2.5 concentration is greater than 150 micrograms/cubic meter and is less thanEqual to 250 micrograms/cubic meter；Then regard as yellowness ratings.
When haze detection device 9, which detects haze grade, does not reach yellowness ratings ratings above, then haze detection device 9Signal is not sent to controller 5, when pedestrian detection device detects pedestrian, then pedestrian detection device sends a signal to controller5, controller 5 determines that the signal controller 5 of the signal and pedestrian detection device that do not receive haze detection device 9 simultaneously is not sentTo warning lamp 8, warning lamp 8 is not received by control signal and does not work signal；
When haze detection device 9, which detects haze grade, reaches yellowness ratings ratings above, then haze detection device 9 is to controlDevice 5 processed sends signal, and when pedestrian detection device detects pedestrian, then pedestrian detection device sends a signal to controller 5, controlDevice 5 determines while receiving the signal of haze detection device 9 and the signal of pedestrian detection device, and controller 5 sends a signal to policeShow that lamp 8, warning lamp 8 start to flash, has pedestrian in front of warning driver.
The beneficial effect that the present apparatus obtains is: when haze weather has pedestrian to cross highway, being controlled and is warned by above-mentioned signalLamp 8 reminds driver, and the traffic accident that can reduce haze weather occurs.This warning lamp 8 is served as a warning in continuous flashing, is slowed downThe speed of driver, speed reduce the generation to cut down traffic accidents.
