Therefore, the scope and configuration relationship of the attached drawings should not be limited to the scope of patent application of the present invention. Narration.

Hereinafter, the detection vehicle according to the present invention will be described with reference to the related drawings. For the sake of understanding, the same components in the following embodiments are denoted by the same reference numerals.

Please refer to FIG. 1 , which is a schematic diagram of a first embodiment of a system for detecting a detection device of the present invention. As shown, the system 1 for detecting a vehicle detecting device includes a plurality of vehicle detecting devices 10, a plurality of image capturing devices 11 and detecting devices 12. The plurality of vehicle detecting devices 10 respectively detect at least one of the vehicles in the passing area to generate the vehicle detecting information 100. The plurality of image capturing devices 11 respectively capture at least one of the vehicles in the passing region to generate the vehicle image information 110. The detecting device 12 is coupled to the plurality of vehicle detecting devices 10 and the plurality of image capturing devices 11 . The detecting device 12 determines that the difference between the vehicle detecting information 100 and the vehicle image information 110 is greater than a preset value. When the threshold value is 121, the detecting device 12 determines the vehicle detecting information 100 according to the preset threshold value 122 and the parameter reasonable algorithm 123 to generate the vehicle detecting device detecting information 124.

Specifically, the system 1 for detecting a vehicle detecting device of the present invention sets an image capturing device at the same time by setting the same section of the vehicle detecting device, and detects information and vehicle image information through the comparison vehicle. To determine whether the data measured by the vehicle detection device is correct. Therefore, the system 1 for detecting the vehicle detecting device of the present invention simultaneously sets the vehicle detecting device 10 and the image capturing device 11 in different regions (such as highways, urban roads, and provincial roads) for traffic. The collection of the flow data, wherein the vehicle detection device 10 can be a vehicle detector (VD) (which includes a coil type, a microwave type, an infrared type, etc.), and the image capturing device 11 can be a closed circuit television (CCTV).

Then, in the same area of the vehicle detecting device 10 and the image capturing device 11, the vehicle detecting device 10 detects at least one of the vehicles passing through the area. (eg, a vehicle) to generate vehicle detection information 100, and image capture device 11 also captures at least one of the vehicles passing through the area to generate vehicle image information 110. Then, the vehicle detection device 10 and the image capturing device 11 can respectively transmit the vehicle detection information 100 conforming to the standard traffic information standard V1.1 of the road test facility defined by the Ministry of Communications by means of wired or wireless transmission. And the vehicle image information 110 is transmitted to the detecting device 12, wherein the detecting device 12 can be a servo terminal (such as a traffic control monitoring center).

Finally, the detecting device 12 performs the first stage check comparison on the vehicle detection information 100 and the vehicle image information 110 transmitted by the vehicle detecting device 10 and the image capturing device 11 disposed in the same area to generate a The difference value is 120, and whether the difference value 120 is greater than the preset threshold value 121. The preset threshold value 121 can be defined by the monitoring center personnel according to different regional conditions. If it is less than the preset threshold value 121, it is determined that the data measured by the vehicle detecting device 10 is accurate information; if the detecting device 12 determines that the difference value 120 is greater than the preset threshold value 121, the detecting device 12 performs the second phase check. The core determines whether the vehicle detection information 100 meets the preset threshold value 122. If the detecting device 12 determines that the vehicle detection information 100 meets the preset threshold value 122, the detecting device 12 performs a third stage check, and calculates the vehicle detection information 100 according to the parameter reasonable algorithm 123 to obtain the vehicle. The detection device detects the information 124, and the vehicle detection device detection information 124 determines that the data measured by the vehicle detection device 10 is accurate information.

If the vehicle detection information 100 does not comply with the second stage check or the third stage check, the generated vehicle detection device detection information 124 determines that the data measured by the vehicle detection device 10 is For inaccurate information, the vehicle detection device 10 is required to be inspected.

In addition, the system 1 for detecting the vehicle detecting device preferably further includes a storage device 13 coupled to the plurality of vehicle detecting devices 10, the plurality of image capturing devices 11 and the detecting device 12, and the storage device 13 storing the carrier Detection information 100 and vehicle image information 110. That is, the system 1 for detecting a vehicle detecting device of the present invention can be used as a database for storing relevant information of the vehicle detecting information 100 and the vehicle image information 110 by setting the storage device 13.

Please refer to FIG. 2, which is a schematic diagram of a second embodiment of a system for detecting a vehicle detecting device of the present invention. Please also refer to Figure 1 together. As shown in the figure, the system for detecting the vehicle detecting device in this embodiment is similar to the operation of the same component described in the system for detecting the detecting device of the first embodiment, and therefore will not be described herein. However, it is worth mentioning that, in this embodiment, the plurality of vehicle detecting devices 10 respectively include a first positioning module 101, which generates first positioning information 102 according to the current position of the vehicle detecting device 10, The image capturing device 11 includes a second positioning module 111, which generates second positioning information 112 according to the current position of the image capturing device 11, and the detecting device 12 compares the plurality of first positioning information 102 with a plurality of second positioning positions. The information 112 is determined, and the at least one first positioning information 102 of the plurality of first positioning information 102 meets at least one second positioning information 112 of the plurality of second positioning information 112, and the detecting device 12 is configured according to at least one first positioning. The information 102 and the at least one second positioning information 112 generate the detection group information 125 and store it to the storage device 13.

For example, the vehicle detecting device 10 of the present invention is provided with a first positioning module 101, the image capturing device 11 is provided with a second positioning module 111, and the first positioning module 101 and the second positioning module 111 are provided. The first positioning information 102 and the second positioning information 112 are generated according to the positions currently set by the vehicle detecting device 10 and the image capturing device 11, wherein the first positioning information 102 and the second positioning information are respectively generated. The message 112 can be a GPS coordinate.

Next, the detecting device 12 compares the plurality of first positioning information 102 and the plurality of second positioning information 112, and the detecting device 12 determines at least one first positioning information 102 and a plurality of the plurality of first positioning information 102. When the at least one second positioning information 112 of the second positioning information 112 is the same GPS coordinate, the detecting device 12 groups the first positioning information 102 and the second positioning information 112 into the same group, and generates the detection group information. 125, and the detection group information 125 is stored to the storage device 13.

It should be noted that, since the system for detecting the vehicle detecting device of the present invention simultaneously sets the vehicle detecting device 10 and the image capturing device 11 in different regions, the carrier detecting device 10 in the same region is The positioning information 102 and the second positioning information 112 of the image capturing device 11 can be grouped into the same group, and a plurality of different regions have a plurality of detecting group information 125.

Further, the vehicle detection information 100 may include a first average vehicle speed value 1000 and a first traffic flow value 1001, and the detecting device 12 may include a processing module 126, and the processing module 126 calculates an image according to the image recognition algorithm 127. The vehicle image information 110 generated by the device 11 during the preset statistical period is generated to generate a second average vehicle speed value 1100 and a second vehicle flow value 1101.

In the above, the processing module 126 determines the first average vehicle speed value 1000 of the vehicle detection information 100 corresponding to the at least one first positioning information 102 in the detection group information 125, and compares at least one second in the detection group information 125. The second average vehicle speed value 1100 of the vehicle image information 110 corresponding to the positioning information 112, or the first traffic value 1001 of the vehicle detection information 100 corresponding to the at least one first positioning information 102 of the group information 125, Aligning detection group information 125 at least When the difference value 120 of the second traffic value 1101 of the vehicle image information 110 corresponding to the second positioning information 112 is greater than the preset threshold 121, the processing module 126 is based on the preset threshold value 122 and the parameter reasonable algorithm. The first average vehicle speed value 1000 or the first vehicle flow rate value 1001 is discriminated to generate the vehicle detection device detection information 124 corresponding to the detection group information 125.

That is, the system 1 of the detection device detecting device of the present invention reads any group of detection group information 125 from the storage device 13, and uses the image recognition software to detect the group information 125 by the image recognition algorithm 127. The image stream of the image information 110 in the vehicle is analyzed and counted, and after the second average vehicle speed value 1100 and the second traffic volume value 1101 in the preset statistical period are calculated, the vehicle is detected during the preset statistical period. The first average vehicle speed value 1000 detected by the measuring device 10 and the first vehicle traffic value 1001 are compared to generate a difference value 120. That is, when the vehicle detection device 10 detects that the preset statistical period of the vehicle detection information 100 generated by the carrier is 00:00:00 to 00:01:00, the processing module 126 captures the image. The device 11 counts the stream images captured from 00:00:00 to 00:01:00 to become the vehicle image information 110, and when the image capturing device 11 captures the image, the preset statistical period reaches 00:01. At 00, the processing module 126 stores the statistical result to the storage device 13, and zeros the relevant statistical parameter of the vehicle image information 110 to restart counting the preset statistical period.

Then, the processing module 126 takes out the vehicle image information 110 of the past minute from the storage device 13 and compares it with the vehicle detection information 100 counted by the processing module 126. If the difference value 120 exceeds the preset threshold When the value is 121, the preset threshold threshold 122 and the parameter reasonable algorithm 123 are used to compare the data measured by the vehicle detecting device 10 and the image capturing device 11 with each other, if the image capturing device 11 The measured data is not passed through one of the comparison methods, then the monitoring The center personnel can check whether the image capturing device 11 has an abnormal condition, or the image recognition system of the image capturing device 11 may need to adjust the identification parameter to improve the measurement accuracy, and if the vehicle detecting device 10 detects the vehicle, If the information 100 fails to pass the comparison mode, the monitoring center personnel can check that the vehicle detecting device 10 may be abnormal, thereby allowing the maintenance personnel to clearly grasp the equipment condition of the vehicle detecting device 10. For example, if the monitoring center personnel set the difference threshold value to 20% and the continuous image of the vehicle image information 110 of the image capturing device 11 is to be calculated, the result is that the traffic volume in the past minute is 10, and the average speed is 40 km/hr. The lane occupancy rate is 9%, while the vehicle detectors reported by the same period of time have 29 traffic flows, the average speed is 15km/hr, and the lane occupancy rate is 10%. Because the average speed difference is more than 20%, it will The threshold threshold 122 is preset to perform the second phase check. The preset threshold value 122 determines the average vehicle speed value and the vehicle flow value respectively, and may define different preset threshold values according to different regional levels. For example, one minute average limit value of the expressway is greater than 0 km/hr. Less than 200km/hr, the flow rate of one-lane traffic in one minute is greater than 0 and less than 40. If the preset threshold value of the general provincial road is different from the expressway, the preset threshold value can be adjusted by the monitoring center personnel according to different regional environments. Set by the situation.

Moreover, if the vehicle detection information 100 of the vehicle detecting device 10 meets the preset threshold value, the third stage check is performed by the parameter reasonable algorithm 123. The parameter reasonable algorithm 123 is divided into two parts. The first part is to judge whether the average vehicle speed value and the traffic flow value have a value of 0. If there is a value of 0, the average vehicle speed value and the traffic flow value must both be 0. The second part is when the two parameters are not 0. The formula "2 meters < average length = ((10 ^* average speed) / (40 ^* one minute traffic)) < 18 meters" is used to judge whether the relationship between the two parameters is correct. If the average length of the vehicle calculated according to this embodiment is 0.86 meters, which is not in accordance with this formula, the monitoring center personnel can be alerted by sending a warning message.

It is worth noting that the above comparison and calculation method can also increase the data of lane occupancy. Therefore, the formula can also be "2 meters < average vehicle length = ((10 ^* average speed ^* lane occupancy) / (40 ^* One minute traffic)) <18 meters.

Please refer to FIG. 3, which is a schematic diagram of a third embodiment of a system for detecting a vehicle detecting device of the present invention. Please also refer to Figure 1 to Figure 2. As shown in the figure, the system for detecting the vehicle detecting device in this embodiment is similar to the operation of the same components described in the system for detecting the detecting device of the above embodiments, and therefore will not be described herein. However, it is worth mentioning that in the present embodiment, the detecting device 12 can include a warning module 128 coupled to the processing module 126. The processing module 126 determines the vehicle detecting device detection information during the preset calculation period. When the abnormal parameter information 129 meets the preset abnormal condition, the processing module 126 drives the alert module 128 to issue the alert message 1280.

That is, the system 1 of the detection vehicle detecting device of the present invention checks the vehicle detection device detection information 124 of the detection group information 125 of each group during the preset calculation period, for example, if the monitoring center personnel detect The system 1 of the vehicle detecting device sets the detection information of the vehicle detecting device 124 of the detection group information 125 of the system to notify the alarm when the abnormal amount exceeds the set allowable threshold value during the preset calculation period of one hour, and then detects The system 1 of the vehicle detection device will perform the statistics of the vehicle detection device detection information 124 every hour. If the abnormal proportion exceeds the set allowable threshold value, an alarm notification will be sent.

Therefore, the system 1 for detecting the vehicle detecting device of the present invention is minutely The clock will take out the vehicle detection device detection information 124 and an abnormal notification related parameter from the storage device 13 to determine whether the devices of the vehicle detection device 10 and the image capturing device 11 corresponding to each group meet the preset abnormal conditions. If it is met, it will judge whether the preset alarm condition has been reached. If the preset alarm condition has been reached, the processing module 126 will prompt the warning module 128 to issue a warning message 1280 to notify the monitoring center personnel.

For example, the monitoring center personnel set an hourly check, and if the vehicle detecting device 124 and the abnormal parameter information 129 exceed 30% of the data abnormality, an alarm notification is performed. Moreover, the processing module 126 takes out the vehicle detection device detection information 124 of the past hour every hour. If the number of abnormalities of the vehicle detection device 124 in a certain group exceeds 30%, An alarm is issued.
