Abstract
The utility model relates to a kind of visibility tester, it comprises infrared light pulse emitter and the receiving trap of microprocessor controls, and microcontroller is electrically connected with infrared light pulse emitter and receiving trap, be also provided with the light shield that blocks direct projection or indirect astigmatism in infrared light pulse emitter one side.The utility model, by the difference of the light intensity of the infrared light pulse of measurement emitter and receiving trap, is realized the concentration determination of suspended particles in atmosphere, according to national testing standard, converts the concentration value of suspended particles to visibility value.Can be according to the current restricted driving speed of this visibility value adjustment.
Description
Technical field
The utility model belongs to road traffic facility technical field.
Background technology
The way that at present traffic monitoring is generally all adopted camera head monitor, it can only realize the candid photograph to traffic violation, cannot complete for the detection of road situation.Along with vehicle increase and high-grade highway more and more, for high-grade highway, management has proposed more and more higher requirement.
My vehicle supervision department does not have to realize to road environment as the equipment of the detection of visibility at present, cannot be in real time according to environmental aspect, and automatic alarm, real time modifying speed(-)limit sign display board.
Summary of the invention
The utility model object is a kind of visibility tester of design, to realize the real-time monitoring to road environment.
Visibility tester, it comprises infrared light pulse emitter and the receiving trap of microprocessor controls, and microcontroller is electrically connected with infrared light pulse emitter and receiving trap, be also provided with the light shield that blocks direct projection or indirect astigmatism in infrared light pulse emitter one side.
The utility model, by the difference of the light intensity of the infrared light pulse of measurement emitter and receiving trap, is realized the concentration determination of suspended particles in atmosphere, according to national testing standard, converts the concentration value of suspended particles to visibility value.Can be according to the current restricted driving speed of this visibility value adjustment.
Brief description of the drawings
Fig. 1 is the utility model principle schematic.
Fig. 2 is the utility model work schematic diagram.
Figure number explanation: 1-infrared light pulse emitter, 2-infrared light pulse receiving trap, 3-sample region, 4-light shield, 5-direct projection or indirect astigmatism, 6-microcontroller.
Embodiment
If Fig. 1 is the utility model principle, it utilizes the forward scattering principle of light, utilize microprocessor controls emitter transmitting infrared light pulse, receiving trap receives the infrared light pulse of transmitting simultaneously, by measuring the difference of light intensity of infrared light pulse of emitter and receiving trap, realize the concentration determination of suspended particles in atmosphere, according to national testing standard, convert the concentration value of suspended particles to visibility value.
Structural representation while being the utility model work as Fig. 2, visibility tester, it comprises infrared light pulse emitter 1 and receiving trap 2 that microcontroller 6 is controlled, and microcontroller 6 is electrically connected with infrared light pulse emitter 1 and receiving trap 2, be also provided with the light shield 4 that blocks direct projection or indirect astigmatism in infrared light pulse emitter 1 one sides.
