Fig. 2 is embodiment 2 tunnel inlet port detection module distribution plan.
Embodiment
Below in conjunction with accompanying drawing the present invention done and further explain.
Tunnel illumination is divided into entrance illumination, transition section illumination, interlude illumination and outlet section illumination.Wherein require relative to other sections more strict to entrance illumination, require that brightness is reduced to lower level gradually from bright luminous environment.Daytime, the brightness calculation of tunnel portal section illumination will be determined according to factors such as the luminance of outer caves, design speed, visual field and length of tunnel.Brightness detection unit is under sunshine direct projection and backlight situation, and the gap of brightness data is huge.If the brightness detection unit of tunnel face only gathers the brightness value of single position, when equipment failure or communication disruption, intensity mode cannot be used to control, the filtering of single its value of detecting unit is bigger than normal in addition, easily causes frequent switch lamp group to operate.
As shown in Figure 1, a kind of tunnel brightness detection system, comprises the detection module being arranged on tunnel portal section, transition section, interlude and outlet section respectively, also comprises host computer.Detection module includes imageing sensor, flush bonding processor, data-carrier store, display screen and wireless transmitter module.Imageing sensor is for the image that gathers in corresponding tunnel construction sections and be stored in data-carrier store.Flush bonding processor is used for control chart image-position sensor, and calculates the brightness value in corresponding tunnel construction sections according to image in data-carrier store.Brightness value is sent to host computer by wireless transmitter module.Flush bonding processor in display screen connection detection module, for showing the brightness value of current detection position, tunnel in real time.Wherein, flush bonding processor adopts model to be STM32F103ZET6 processor, and imageing sensor adopts model to be OV7670CMOS imageing sensor.
In the present embodiment, tunnel portal section and outlet section are respectively equipped with three detection modules, are separately positioned in the middle of left tunnel curb, road surface and right wing edge.The control that can reduce illumination like this relies on the height of single brightness detection unit, adopts the average of regional luminance data herein, and when avoiding tunnel face airfield equipment backlight, collection value is too low and cause tunnel face to throw light on the appearance of the abnormal conditions such as deficiency.
Wherein, image input device comprises camera lens, cmos sensor, A/D converter and dsp processor.Camera lens and cmos sensor are packaged together, and its output terminal is connected to A/D converter, and the image of camera shooting does after image enhaucament, filtering and edge extracting process through dsp processor and is input in data-carrier store after sampling, quantification treatment.Embedded microprocessor calculates the brightness value of this picture according to brightness of image calculating method, and gets average according to the brightness value that the multiple detection modules in same tunnel construction sections obtain, and obtains the brightness value closer to intrinsic brilliance.The brightness value of the different tunnels end wireless transmitter module also in logical detection module links host computer, and this master system can control the brightness of illumination in tunnel according to the brightness value of the different tunnel construction sections of feedback, make tunnel overall brightness balanced.
Embodiment 2: be only with the difference of embodiment 1, in the present embodiment, tunnel portal section and outlet section are respectively equipped with 7 detection modules, are separately positioned in the middle of left tunnel curb, road surface and right wing edge.As shown in Figure 2,7 module mounting points are respectively road center, left 1/4 road surface, left edge, right 1/4 road surface, right wing edge, totally 5 points.At the above l rice of foundation to 2 meters in the localities, benefit surveys some brightness references as a setting.During test, synchronization is surveyed to centre from two tunnel faces simultaneously, and each measuring point reads 3 secondary data and asks its mean value, then obtains the illumination mean value in this region, is the average brightness value on road surface.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
