Fig. 2 is two adjacent scan-types of a kind of tunnel traffic event detection system that one embodiment of the utility model provides
Laser sensor scheme of installation.
Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing, needs to illustrate herein
, detailed description below is only used for clearly illustrating the technical solution of the utility model, but does not form to this
The restriction of utility model.
Fig. 1 is the structure diagram of a kind of tunnel traffic event detection system that one embodiment of the utility model provides, such as
Shown in Fig. 1, the system is made of background monitoring unit, display unit and several event detection units.The event detection
Unit is made of scanning type laser sensor, data processing unit, camera unit and network communication unit.
The scanning type laser sensor be mounted on tunnel side, the plane of scanning motion of the scanning type laser sensor with
Track is parallel, and the height of the plane of scanning motion of the scanning type laser sensor apart from ground can adjust as needed, for example, institute
Height of the plane of scanning motion of scanning type laser sensor apart from ground is stated as 800mm, the object on track highly less than 800mm exists
Under the plane of scanning motion of the scanning type laser sensor, therefore the scanning type laser sensor can not measure height on track
Location information less than 800mm, since the minimum altitude of car is 1300mm, the scanning type laser sensor is swept
The height for retouching plan range ground is no more than 1300mm.
The data processing unit is connect with the scanning type laser sensor by cable, at the data processing unit
The ranging information of the scanning type laser sensor is managed, judges whether is vehicle in the range of the scanning type laser sensor instrument distance
Whether there is abnormal projected object in the range of parking and the scanning type laser sensor instrument distance.Specifically, when vehicle drives into described sweep
When retouching in the finding range of formula laser sensor, the data processing unit handles the ranging letter of the scanning type laser sensor
Breath, obtains the vehicle in the range of the scanning type laser sensor instrument distance to the distance of the scanning type laser sensor, passes through
The vehicle judges whether the vehicle stops to the distance of the scanning type laser sensor；The data processing unit is real
When handle the ranging information of the scanning type laser sensor, obtain object in the range of the scanning type laser sensor instrument distance and arrive
The distance of the scanning type laser sensor, since position of the abnormal projected object on track is fixed, when the object on track
When distance of the body apart from the scanning type laser sensor is constant, so as to judge there is abnormal projected object on track.
The camera unit is connect with the data processing unit by cable, and the camera unit swashs with the scan-type
Optical sensor is mounted on the homonymy in tunnel, and the shooting direction of the camera unit is identical with driveway travel directions, the camera list
The setting angle of member is fixed, and the distance of the camera unit and the scanning type laser sensor is not less than the scanning type laser
The maximum measurement distance of sensor, it is ensured that the camera unit can be taken in the range of the scanning type laser sensor measurement
All areas, when having vehicle parking on track or having abnormal projected object, the data processing unit generates trigger signal
And alarm signal, the camera unit receive the trigger signal of data processing unit, and the vehicle to stopping on track by cable
And abnormal projected object take pictures.
The network communication unit is connect by cable with the camera unit and the data processing unit respectively, described
Network communication unit receives the alarm signal of the data processing unit and the photo of the camera unit, and passes through optical fiber and will shine
Piece and alarm signal are sent to the background monitoring unit, the report that each event detection unit is sent to the background monitoring unit
Alert signal is different, and the background monitoring unit determines the region that traffic events occur in tunnel by alarm signal, and can
The reason of accident occurs is primarily determined with the photo for watching the region.The display unit is mounted on the inlet in tunnel, described
Display unit is connect with the background monitoring unit by cable, and the display unit receives what the background monitoring unit was sent
