Below in conjunction with accompanying drawing, the main of the embodiment of the present application technical scheme is realized principle, embodiment and be explained in detail the beneficial effect that should be able to reach.
The embodiment of the present application provides a kind of Vehicle flow measuring method, and as shown in Figure 1, described method comprises:
S10: in the first moment, is detected by least two sensors being arranged on diverse location in a Vehicle flow measuring region and obtains for characterizing at least two Detection Information whether having obstructing objects in described Vehicle flow measuring region.
S20: according to described at least two Detection Information, judges in described first moment, whether has vehicle by described Vehicle flow measuring region, obtains the first judged result.
In the embodiment of the present application, Vehicle flow measuring region can be positioned at expressway access, urban transport artery or Entrance equipotential are set up, width due to road has certain standard, such as: two-way Four-Lane Road is 2*7.5 rice, two-way six-lane is 2*11.25 rice, due to vehicle in the process of moving, always can not travel the centre position in track, and sensor is arranged on the middle position in track usually, under normal circumstances, when vehicle is positioned at the overlying regions that sensor can detect, sensor can detect in Vehicle flow measuring region to there is barrier.But in reality detects, due to reasons such as vehicle traveling-position skews, the region making vehicle deviate from sensor can to detect, causes sensor vehicle not detected.
Next, step S10 is described.
In step slo, detect in this region whether there is barrier by least two sensors being arranged on the diverse location in Vehicle flow measuring region, obtain multiple Detection Information, then, multiple Detection Information is sent on the terminal device of Vehicle flow measuring system, terminal device can, for having the display terminal of Presentation Function, make managerial personnel can check Vehicle flow measuring situation by display terminal.
In specific implementation process, Vehicle flow measuring region refers to be needed to detect the road area whether having vehicle to pass through, in the embodiment of the present application, two sensors can be set diverse location in Vehicle flow measuring region, or 3 sensors, such as: in Vehicle flow measuring region, be provided with two sensors, in the first moment, to whether there is vehicle in flow surveyed area being detected by these two sensors simultaneously, obtaining two Detection Information in the first moment.
Next, enter step S20, according to described at least two Detection Information, judge in described first moment, whether have vehicle by described Vehicle flow measuring region, obtain the first judged result.
Specifically, if there is at least one effective Detection Information at least two Detection Information, show that, in the first moment, Vehicle flow measuring exists obstructing objects in region, then determine in the first moment, have vehicle by this surveyed area.
Such as a kind of scene is, diverse location place in Vehicle flow measuring region is provided with 4 sensors, in the first moment, terminal device receives 4 Detection Information that sensor detects, wherein, there is a Detection Information to show that Vehicle flow measuring region exists barrier, then determine in the first moment, have vehicle by this surveyed area.
Next, the sensor setting in the embodiment of the present application is described.
Specifically, in Vehicle flow measuring region, diverse location is provided with at least two sensors, and specifically, can arrange 2 or 4 sensors, the type of sensor can be identical, also can be different, and the application does not all limit this.Such as: sensor can be one or more the combination in geomagnetic sensor, pressure transducer, infrared sensor and laser sensor, and multiple sensor arranges according to certain arranging rule.
In the embodiment of the present application, arranging rule can have following three kinds of situations.
The first situation, Vehicle flow measuring region longitudinally arranges multiple sensor, to reduce the impact that the accuracy of the speed of a motor vehicle on Vehicle flow measuring causes.As shown in Figure 2, vehicle is when by flow detection region, successively by sensor 1 and sensor 2, a sensor then in sensor 1 and sensor 2 detects that flow detection overlying regions exists barrier, or sensor 1 and sensor 2 all detect that flow detection overlying regions exists barrier, vehicle just can be defined by flow detection region.
The second situation, the multiple sensor of horizontally set on Vehicle flow measuring region, offsets to reduce vehicle traveling-position the impact caused the accuracy of Vehicle flow measuring.
In reality detects, suppose that sensor 1 is positioned at the centre position in vehicle detection region, be the region that can detect of sensor 1 in dotted line circle in Fig. 2, namely, effective surveyed area, suppose that vehicle is when by flow detection region, skew centre position, then sensor 1 cannot detect effective Detection Information that vehicle passes through, therefore, can on vehicle detection region the multiple sensor of horizontally set, as sensor 3 and sensor 4, when any one sensor then in sensor 3 and sensor 4 detects that flow detection overlying regions has a barrier, define vehicle by flow detection region.
The third situation, horizontal and vertical on Vehicle flow measuring region arranges multiple sensor simultaneously, offsets to avoid the speed of a motor vehicle and vehicle traveling-position simultaneously the impact caused the accuracy of Vehicle flow measuring.
In actual applications, when any one sensor in sensor 1, sensor 2, sensor 3 and sensor 4 detects that flow detection overlying regions has a barrier, then vehicle is defined by flow detection region.
In the embodiment of the present application, after step S20, described method also comprises:
When the first judged result is for being, generate vehicle detection result, described vehicle detection result is carved with vehicle by described Vehicle flow measuring region when being used for being characterized in described first, and upgrades the vehicle detecting information in vehicle detection database according to this vehicle detection result.
Specifically, geomagnetic sensor can be used for the existence and the vehicle cab recognition that detect vehicle, and pressure transducer can detect the existence of vehicle, and the weight of vehicle, therefore, vehicle detection result can only include the time that vehicle passes through, and can also comprise the parameter such as vehicle, weight.
In the embodiment of the present application, vehicle detection database refers to for preserving in a period of time, the database of the vehicle flow situation in one or more Vehicle flow measuring region, in specific implementation process, terminal device can carry out real-time update according to vehicle detection result to the information in vehicle detection database, also can periodically upgrade the information in vehicle detection database, the application does not limit this.
In the embodiment of the present application, according to the duration of effective Detection Information, condition of road surface can also be determined.Specifically, after determining that the Detection Information of sensor is effective Detection Information, the lasting duration of effective Detection Information is obtained; And obtain the multiple lasting duration be engraved in when comprising described first in interior first time period; Then, according to described multiple lasting duration, analyze the road conditions obtaining Vehicle flow measuring region place in described first time period.
Next, be described by the analytical approach of object lesson to road conditions, suppose that a Vehicle flow measuring region has 30 cars to pass through in first time period, wherein, in 30 Detection Information detected, have the lasting duration of 25 Detection Information more than 1 minute, the time namely having 25 cars to stop in Vehicle flow measuring region was more than 1 minute, then can determine within the first period, the road traffic congestion at this place, Vehicle flow measuring region.
In specific implementation process, can also be positioned at the Parameter analysis road conditions such as average duration or maximum duration in Vehicle flow measuring region in conjunction with vehicle, the application does not limit this.
