Description

  The present invention relates to a patrol monitoring support system and a patrol monitoring support method for supporting the efficiency of patrol monitoring to an area having a cap road.

  When the company manages pipes such as water pipes and gas pipes, patrol monitoring is performed as maintenance work for the pipes. In this patrol monitoring, patrol workers periodically patrol the area where pipes such as water pipes and gas pipes managed by the company are laid with patrol vehicles, and other companies' construction (for example, water pipe construction) Make sure that your company's conduits (eg gas pipes) are not damaged or not. In this way, people and time are required to perform patrol monitoring.

  Usually, since the area where the conduits to be visited are laid is wide, there is a problem of how efficiently the circulation is performed with limited resources (people and time). For this reason, for example, Patent Document 1 discloses another company construction management system that provides information related to patrol using a car navigation device mounted on a patrol vehicle by associating the status of the construction of the other company with its own conduit. In this other company's construction management system, the construction schedule information acquired in advance and the security target area of the company are displayed on the map of the car navigation device. As a result, other companies' construction (for example, water pipe construction), etc. that may affect the company's own pipe (for example, gas pipe) can be easily confirmed, and it is limited because it is possible to know the area to be circulated on a priority basis. It is possible to make efficient patrols in a long time.

JP 2011-210172 A

  However, the above system is useful when the range of regular patrol vehicles (such as urban areas) and the status of construction work by other companies can be grasped in advance, but away from the usual patrol route, such as mountainous areas. If it becomes a traveling target area that exists in isolation, a lot of unnecessary travel time occurs, which is inefficient. In particular, when the isolated area to be visited has a road with a narrow path, the traveling vehicle has no choice but to turn back the way it came, resulting in a large time loss.

However, there is no known system for efficiently performing patrol monitoring when there is an isolated patrol area and construction information cannot be acquired in advance. The efficiency of patrol monitoring has not been established.
The present invention has been made in view of the above circumstances, and the purpose thereof is to efficiently perform patrol monitoring of an area having a road that is in the form of a narrow path. It is to realize a patrol monitoring support system that provides information useful for judgment. A second object is to establish a patrol monitoring support method for efficiently carrying out patrol monitoring to an area having a road that has a narrow path.

In order to achieve the above object, the characteristic configuration of the patrol monitoring support system according to the present invention is a patrol monitoring support system that supports the efficiency of patrol monitoring to an area having a narrow alley road,
First vehicle detection means comprising a photographing device installed so as to photograph a vehicle entering the region at an entrance / exit corresponding to the entrance / exit of the bag path road;
Second vehicle detection means comprising a photographing device installed to photograph a vehicle exiting from the area at the entrance / exit location;
A monitoring server capable of outputting a captured image of the vehicle photographed by the first vehicle detection means and the second vehicle detection means to the outside,
Each of the first vehicle detection means and the second vehicle detection means
Vehicle recognition means for recognizing a vehicle included in a photographed image photographed by the photographing device;
A detection result for outputting to the monitoring server, as a detection result, the captured image that can be recognized by the vehicle recognition means as including a vehicle, the license plate number included in the captured image, and the shooting time of the captured image. An output unit,
The monitoring server is
Storage means for storing each of the detection results output from the detection result output unit of the first vehicle detection means and the second vehicle detection means;
Comparing the detection result output from the first vehicle detection means stored in the storage means with the detection result output from the second vehicle detection means stored in the storage means; An extraction unit for extracting the number matches as an extraction result;
For each of the extraction results, the difference between the shooting time included in the detection result output from the first vehicle detection means and the shooting time included in the detection result output from the second vehicle detection means. A stay time calculation unit for calculating as a stay time;
Among the extraction results, the stay time is a predetermined time or more, and the stay time is combined as monitoring target data, and a monitoring target output unit configured to freely output a list of the monitoring target data to the outside,
It is in the point provided with.

According to the above characteristic configuration, the vehicle recognizing means photographs the vehicle entering the area having the baggage road with the photographing device of the first vehicle detecting means, and exits from the area by the photographing device of the second vehicle detecting means. You can take a picture of the vehicle. Then, the captured image including the vehicle, the license plate number, and the captured time can be output as a detection result to the monitoring server. In the monitoring server, two detection results from the first vehicle detection means and the second vehicle detection means having the same license plate number are extracted as extraction results, and the time from entry to exit in the area is determined from the extraction results. Only those having a certain stay time over a predetermined time can be output to the outside as a list of monitoring target data.
Here, by setting a predetermined time, for example, longer than the time required to turn back a normal narrow road, vehicles with a stay time longer than the predetermined time, for example, loaded and unloaded heavy machinery used in construction of other companies. It may be related to the construction of other companies. For this reason, when there is a vehicle that has stayed for a predetermined time or longer, the necessity of patrol monitoring in the area is increased.
That is, the monitoring server is configured not to simply monitor all the vehicles entering and leaving the area, but to selectively output only those that may require patrol monitoring. For this reason, the traveling worker can reduce the burden of browsing the list of monitoring target data output from the monitoring server, and can efficiently determine the necessity of traveling monitoring.
In addition, since the monitoring target data includes the captured image of the vehicle at the time of entry / exit of the area captured by the first vehicle detection means and the second vehicle detection means, the traveling worker confirms the captured image of the vehicle, It can be easily confirmed whether the vehicle is a vehicle or the like, that is, whether it is necessary to perform patrol monitoring. When a patrol worker confirms a construction vehicle of another company, it is better to go to patrol monitoring.
With the above configuration, the patrol operator can perform patrol monitoring only when there is a high necessity for patrol monitoring based on the output from the monitoring server, without periodically patroling the area having the narrow path road. The frequency of going to patrol monitoring within can be suppressed. In this way, patrol monitoring that provides information useful for determining whether or not there is a need for patrol monitoring in an area in order for the patrol operator to efficiently perform patrol monitoring in an area having a road with a narrow path A support system can be realized.

In a further characteristic configuration, the monitoring target output unit of the monitoring server includes:
Among the detection results stored in the storage means, those not extracted as the extraction result by the extraction unit are also set as the monitoring target data, and the list of the monitoring target data can be output to the outside.

  According to the above characteristic configuration, detection results that are not extracted by the extraction unit can be output as monitoring target data in addition to the list of monitoring target data. Here, the detection result that is not extracted by the extraction unit is information related to the vehicle that is detected by only one of the first vehicle detection unit and the second vehicle detection unit. In other words, regarding the vehicle included in the detection result, the first vehicle detection unit and the second vehicle detection unit may still fail to capture the vehicle or after the first vehicle detection unit captures the image. 2 The case where it is not image | photographed by the vehicle detection means can be considered. Therefore, such detection results may not be clearly known for the staying time in the area, may have stayed for a predetermined time or may have been staying, and may be related to other companies' construction. There is. In this regard, this feature configuration suppresses the possibility of overlooking other companies' construction work in the area because vehicles that have stayed or may have stayed for more than a predetermined time are added to the list as monitored data. Can do. That is, it is possible to realize a patrol monitoring support system that provides information that is more useful for determining whether or not patrol monitoring is necessary in an area having a road that has a narrow path.

In addition, in order to achieve the above object, the characteristic configuration of the patrol monitoring support method according to the present invention includes a vehicle that enters the area at an entrance / exit corresponding to the entrance / exit of the sac road, and an area from the area at the entrance / exit A shooting step for shooting the vehicle leaving,
A vehicle recognition step for recognizing a vehicle included in a photographed image photographed by the photographing device;
A detection result output step of outputting, as a detection result, the captured image that has been recognized as including a vehicle by the vehicle recognition step, a license plate number included in the captured image, and a capturing time of the captured image;
A storage step of storing each of the detection results output by the detection result output step;
The detection result including the captured image of the vehicle entering the area stored in the storage step and the detection result including the captured image of the vehicle exiting from the area stored in the storage step. An extraction step for comparing and extracting the number plate number that coincides as an extraction result;
For each of the extraction results, a stay time for calculating a difference between the shooting time of the captured image of the vehicle entering the area and the shooting time of the captured image of the vehicle leaving the area as the stay time A calculation step;
Among the extraction results, the stay time is a predetermined time or more, and the stay time is combined as monitoring target data, and a monitoring target output step for outputting a list of the monitoring target data to the outside,
A construction vehicle extraction step of extracting a construction vehicle of another company from the captured image included in the monitoring target data output to the outside by the monitoring target output step;
Is to execute.

According to the above characteristic configuration, the vehicle that enters the area having the pavement road is photographed by the photographing device of the first vehicle detection means, and the vehicle that leaves the region is photographed by the photographing device of the second vehicle detection means. . And the picked-up image recognized as including the vehicle by the vehicle recognition step, the number plate number, and the photographing time are output as a detection result. Furthermore, two detection results from the first vehicle detection means and the second vehicle detection means having the same license plate number are extracted as extraction results, and the stay is the time from entry to exit from the extraction results. Only those whose time is equal to or longer than a predetermined time are output to the outside as a list of monitoring target data.
In addition, in the construction vehicle extraction step, among the monitoring target data output to the outside in the list, data whose construction vehicle of another company is included in the photographed image is extracted.
By executing the above steps, it is possible to selectively find a construction vehicle of another company that entered the area and stayed in the area for the construction. And when the patrol worker confirms the photographed image of the construction vehicle of another company, it is better to go to patrol monitoring.
With the above configuration, the patrol operator can perform patrol monitoring only when there is a high need for monitoring based on the output from the monitoring server, without periodically patroling the area having the cover road. The frequency of going to patrol monitoring can be reduced. In this way, patrol monitoring that provides information useful for determining whether or not there is a need for patrol monitoring in an area in order for the patrol operator to efficiently perform patrol monitoring in an area having a road with a narrow path Support method can be realized.

1. Schematic Configuration A tour monitoring support system 1 according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the patrol monitoring support system 1 monitors the vehicle 2 entering and exiting the area A having the culvert road B, and the patrol worker determines whether or not patrol monitoring is necessary. By providing useful information, it is configured to support the efficiency of patrol monitoring to the area A. In the present embodiment, the company conducts maintenance management work for the conduit C in the area A, and performs patrol monitoring of the area A. The purpose of the patrol monitoring in the area A is to prevent the pipe C managed by the company from being damaged due to the construction of other companies, and the patrol monitoring support system 1 is used to efficiently perform the patrol monitoring. A vehicle that enters and exits the area A using the road B is configured to be monitored. More specifically, the patrol monitoring support system 1 monitors the construction vehicles of other companies that enter and exit the area A.

  Here, the company's conduit C is a gas pipe, and the construction of other companies means sewerage work, utility pole installation work, and the like. The construction vehicle of another company means a vehicle loaded with heavy machinery such as an excavator. That is, the patrol monitoring support system 1 in this embodiment is operated by a gas company, and the construction of other companies means construction for underground buried objects other than gas pipes that are the company's own conduit C and transmission lines.

  In the present embodiment, the area A in FIG. 1 is a target area for patrol monitoring, and in this area, there is a culvert road B and its own conduit C in the form of being buried under the sac path road B. To do. The area A is branched as shown in the figure, and is usually at a position away from the city area D, which is a patrol route for patrol monitoring. In addition, although omitted in the drawing, it is assumed that there is a conduit to be visited in the city area D.

  The cul-de-sac road B has a sac-path shape that can be entered only from the left side in the figure. The site X which the company owns is provided in the location which becomes the entrance / exit of the sac path road B. The site X corresponds to an “entrance / exit location” in the present invention.

  The conduit C is a gas pipe, and in the section of the region A, the conduit C is buried and laid in the basement of the culvert road B. The conduit C is protected by a mountain tunnel at a location following the right side in the drawing of the region A (in the drawing, a section where the conduit C is protected is indicated by a broken line). For this reason, in the area A, the conduit C may be damaged by construction work by other companies such as excavation, and the area A is an area to be monitored.

  As shown in FIG. 2, the patrol monitoring support system 1 is based on two vehicle detection means 10 for detecting a vehicle 2 entering and exiting an area A and a detection result 100 sent from the two vehicle detection means 10. The monitoring server 20 is configured to freely output monitoring target data. The patrol worker refers to the monitoring target data output from the monitoring server 20, determines whether or not patrol monitoring in the area A is necessary, and performs patrol monitoring in the area A as necessary.

  In the present embodiment, two vehicle detection means 10 are installed on the site X shown in FIG. 1 to monitor a vehicle that enters or leaves the area A. As will be described in detail later, the vehicle detection means 10 is roughly composed of an imaging device 11 for imaging the vehicle 2 and a vehicle detection device 12 for detecting the vehicle 2 from an image captured by the imaging device 11.

  The first vehicle detection means 10 a, which is one of the two vehicle detection means 10, is installed so that the imaging device 11 images the vehicle 2 entering the area A at the site X. The other second vehicle detection means 10b is installed so that the photographing device 11 photographs the vehicle 2 leaving the area A at the site X.

  The monitoring server 20 is configured to be able to output monitoring target data including captured images captured by the first vehicle detection unit 10a and the second vehicle detection unit 10b to the outside. The monitoring server 20 is installed at a location different from the site X. Below, the vehicle detection means 10 and the monitoring server 20 are demonstrated in detail.

1-1. Configuration of Vehicle Detection Unit The first vehicle detection unit 10a and the second vehicle detection unit 10b are configured by the same hardware and software except that the shooting direction (shooting location) of the shooting device 11 is different as described above. Is done. Below, the 1st vehicle detection means 10a and the 2nd vehicle detection means 10b are put together, and are demonstrated as the vehicle detection means 10. FIG.

  The vehicle detection means 10 includes a photographing device 11 and a vehicle detection device 12 broadly. In the present embodiment, the photographing device 11 is configured to periodically photograph the state on the road and send the photographed photographed image to the vehicle detection device 12. In addition, the photographing device 11 is configured so that a photographing range is a range in which the type of the traveling vehicle can be determined from the photographed image.

  The vehicle detection device 12 includes a computer including an arithmetic processing device and a storage device, and includes a plate recognition unit 13, a number recognition unit 14, and a detection result output unit 15 as programs for performing various processes. The plate recognition unit 13 recognizes a license plate included in a photographed image of the vehicle photographed by the photographing device 11. The license plate recognition method by the plate recognition unit 13 can be performed, for example, by extracting a vertical edge component in a captured image. Here, the plate recognition unit 13 corresponds to a “vehicle recognition unit”.

  The number recognition unit 14 recognizes a license plate number included in the captured image. Here, the “number plate number” means “automobile registration number” in the Road Transport Vehicle Law, and consists of numbers and letters. For the recognition of shapes and characters in the plate recognition unit 13 and the number recognition unit 14, for example, a known image recognition technique such as pattern matching can be used.

  The detection result output unit 15 detects the photographed image of the vehicle whose plate was recognized by the plate recognition unit 13, the license plate number recognized in the photographed image by the number recognition unit 14, and the photographing time of the photographed image. Output as 100. Further, the detection result 100 is provided with information indicating which one of the first vehicle detection unit 10a and the second vehicle detection unit 10b is output.

  In the present embodiment, even if the license plate number cannot be recognized by the configuration in which the plate recognition unit 13 recognizes the license plate before the license plate number is recognized by the number recognition unit 14, the photographed image including the vehicle is included. Can be acquired, and a captured image that may include a construction vehicle of another company can be output as the detection result 100. That is, it is easier to find the construction vehicle of other companies than the case of directly detecting the license plate number without recognizing the license plate.

  The detection result output unit 15 transmits the detection result 100 to the monitoring server 20 provided remotely using a communication line. In the present embodiment, the detection result output unit 15 is configured to transmit the detection result 100 to the storage unit 21 of the monitoring server 20 via a mobile communication network or the like.

1-2. Configuration of Monitoring Server The monitoring server 20 includes a storage unit 21 and a control unit 27. The memory | storage means 21 is comprised with the database for memorize | stored the detection result 100 output from the detection result output part 15 of the 1st vehicle detection means 10a and the 2nd vehicle detection means 10b.

  The control means 27 is composed of a computer having an arithmetic processing unit and a storage device, and as a program for performing various processes on the detection result 100 stored in the storage means 21, an extraction unit 22, a stay time calculation unit 23, An elapsed time calculation unit 24 and a monitoring target output unit 25 are provided.

  The extraction unit 22 extracts two detection results 100 having the same license plate number from the detection results 100 stored in the storage unit 21 as the extraction result 200. More specifically, the detection result 100 output from the first vehicle detection means 10a stored in the storage means 21 and the detection result 100 output from the second vehicle detection means 10b stored in the storage means 21 are compared. The license plate numbers that coincide with each other are extracted as the extraction result 200.

  The stay time calculation unit 23 includes, in the extraction result 200, the shooting time included in the detection result 100 output from the first vehicle detection unit 10a and the shooting time included in the detection result 100 output from the second vehicle detection unit 10b. Is calculated as the stay time T1.

  The elapsed time calculation unit 24 calculates the difference between the photographing time included in the detection result 100 and the current time for the detection result 100 that is output by the first vehicle detection unit 10a and not extracted as the extraction result 200 by the extraction unit 22. The elapsed time T2 is calculated.

  The monitoring target output unit 25 can freely output information useful for the traveling operator to determine whether or not the traveling monitoring in the area A is necessary based on the information generated by the extracting unit 22 to the elapsed time calculating unit 24. Configured. Hereinafter, the monitoring target output unit 25 will be described in detail.

1-2-1. Monitoring Target Data In this embodiment, the monitoring target output unit 25 broadly categorizes and outputs two types of monitoring target data to a list.

  First, as the first type of monitoring target data, the monitoring target output unit 25 uses the extraction result 200 in which the stay time T1 is equal to or longer than the predetermined time Tx. The predetermined time Tx may be set to a time that is considered to be required when a construction vehicle of another company performs construction in the area A.

  Next, as the second type of monitoring target data, the monitoring target output unit 25 uses the detection result 100 stored in the storage unit 21 that has not been extracted as the extraction result 200 by the extraction unit 22. That is, the detection result 100 output by the first vehicle detection unit 10a or the second vehicle detection unit 10b, and the detection result 100 that does not match the license plate number included in the detection result 100, is the monitoring target data. It becomes.

1-2-2. External output The monitoring target output unit 25 collectively outputs these two types of monitoring target data in a list format as shown in FIG. In the present embodiment, the monitoring target output unit 25 outputs the extraction result 200 and the detection result 100 as monitoring target data in a list in the same display format.

  Specifically, as shown in FIG. 5, the captured image (“entrance image” in the figure) and the photographing time (“entry time” in the figure) included in the detection result 100 by the first vehicle detection means 10a, the second vehicle Captured image (“participation image” in the figure) and photographing time (“participation time” in the figure) included in the detection result 100 by the detection means 10b, license plate number (“car number” in the figure) included in both detection results 100 , And stay time T1 are displayed. When only the detection result 100 by the 1st vehicle detection means 10a is displayed, an entrance image, entrance time, and a vehicle number are displayed. Further, the elapsed time T2 may be displayed as the stay time. At this time, the participation image becomes blank and the participation time is displayed as no record. When only the detection result 100 by the second vehicle detection means 10b is displayed, the entry image is blank, the entry time is displayed as no record, and the entry image, the entry time, and the car number are displayed.

  The output destination of the list by the monitoring target output unit 25 can be the monitoring terminal 4 in the management office where the monitoring server 20 is installed, or the portable terminal 5 or the like. Specifically, it is configured so that it can be output to the mobile terminal 5 possessed by the patrol worker in the patrol vehicle 3. In the present embodiment, when there is a request for monitoring target data from the monitoring terminal 4 or the portable terminal 5, the control unit 27 is configured to output the monitoring target data.

2. System operation 2-1. Operation of Vehicle Detection Device The flow of vehicle detection by the vehicle detection device 12 will be described with reference to FIG.
Sequentially taken images are sent from the photographing device 11 to the vehicle detection device 12. The imaging device 11 is configured to transmit to the monitoring server 20 the received captured image that has been confirmed to have a license plate. Below, the flow when the vehicle detection apparatus 12 receives a captured image from the imaging apparatus 11 is shown.

  When the captured image is sent, the vehicle detection device 12 first checks whether the license plate exists by the plate recognition unit 13 (# 11). If the license plate cannot be recognized, the photographed image is discarded and the process is terminated (# 11: No).

  When the license plate exists (# 11: Yes), a rectangular area corresponding to the license plate is extracted, and the license plate number is searched for the rectangular area (# 12). Here, when the license plate number is not found (# 12: No), the detection result output unit 15 does not know the captured image, the shooting time, and the license plate number as the detection result 100 as the detection result 100. A message to that effect is output (# 13).

  When the license plate number is found (# 12: Yes), the photographed image, the recognized license plate number, and the photographing time are output as the detection result 100 (# 13).

  The captured image in which the presence of the license plate is confirmed as described above is transmitted from the vehicle detection device 12 to the monitoring server 20. The detection result 100 transmitted to the monitoring server 20 is stored in the storage unit 21.

2-2. Operation of Control Unit The flow until the monitoring target data is output by the control unit 27 of the monitoring server 20 will be described with reference to FIG.

  The control unit 27 first acquires the detection result 100 stored in the storage unit 21 by the extraction unit 22 (# 21). Next, it is confirmed whether there is another detection result 100 that includes the same license plate number as the license plate number included in the acquired detection result 100 (# 22). Here, another detection result 100 means the detection result 100 output by the second vehicle detection means 10b when the acquired detection result 100 is output by the first vehicle detection means 10a. When the detected result 100 is obtained by the second vehicle detection means 10b, it means the opposite.

  When the detection result 100 of the same license plate number exists (# 22: Yes), the detection result 100 including the same license plate number is grouped and set as the extraction result 200 (# 23). Subsequently, the stay time calculation unit 23 calculates the stay time T1 of the created extraction result 200 (# 24). If the stay time T1 of the extraction result 200 is equal to or longer than the predetermined time Tx, the extraction result 200 is added to the monitoring target data (# 26).

  By the way, in # 22, when the detection result 100 of the same license plate number does not exist (# 22: No), when the detection result 100 is output by the first vehicle detection means 10a, the elapsed time T2 is calculated. If the detection result 100 is output by the second vehicle detection means 10b, the elapsed time T2 is not calculated (# 29). Thereafter, the detection result 100 is added to the monitoring target data regardless of whether the detection result 100 is output to the first vehicle detection means 10a or the second vehicle detection means 10b (# 26).

  By performing the above steps # 21 to # 26 on all the detection results 100 stored in the storage unit 21, the monitoring target data that is finally output by the monitoring target output unit 25 is generated.

  As described above, it is possible to effectively collect only the monitoring target data useful for determining the necessity of cyclic monitoring from the detection results 100 stored in the storage unit 21 and display it in a list. In addition, because the monitoring target data that is considered to be highly monitored is highlighted, it is possible to identify the monitoring target data that should be noted by the patrol operator with priority, and the need for efficient patrol monitoring. Judgment can be made.

3. Monitoring Method Using System A patrol monitoring support method according to the present invention will be described. In the present embodiment, a tour monitoring support method using the tour monitoring support system 1 will be described as an example. In the present embodiment, the following steps are executed in order as a patrol monitoring support method for supporting the efficiency of patrol monitoring to the area A having the culvert road B.

In the present embodiment, first, using the first vehicle detection means 10a and the second vehicle detection means 10b,
A shooting step of shooting the vehicle 2 entering the area A at the site X and the vehicle leaving the area A at the site X;
A plate recognition step for recognizing a license plate included in a photographed image of the vehicle 2 photographed in the photographing step;
A number recognition step for recognizing a license plate number included in the photographed image;
A detection result output step for outputting a photographed image in which the license plate can be recognized by the plate recognition step, a license plate number recognized by the number recognition step in the photographed image, and a photographing time of the photographed image as a detection result 100;
Execute.

Subsequently, the monitoring server 20
A storage step for storing each of the detection results 100 output by the detection result output step;
The detection result 100 including the captured image of the vehicle 2 entering the area A stored in the storing step is compared with the detection result 100 including the captured image of the vehicle 2 exiting from the area A stored in the storing step. , An extraction step for extracting the license plate number that matches the extraction result 200;
For each of the extraction results 200, a stay time calculation that calculates the difference between the shooting time of the captured image of the vehicle 2 entering the area A and the captured time of the captured image of the vehicle 2 leaving the area A as the stay time T1. Steps,
A monitoring target output step of combining the stay time T1 of the extraction result 200 with the stay time T1 being equal to or longer than the predetermined time Tx and outputting the list of the monitoring target data to the outside.
Execute.

  In the present embodiment, the monitoring server 20 further adds, to the monitoring target data, the detection result 100 stored in the storage step that has not been extracted as the extraction result 200 in the extraction step. .

  Furthermore, the construction vehicle extraction step of extracting the construction vehicle of another company from the captured image included in the monitoring target data output to the outside in the monitoring target output step is performed by the patrol worker. Here, whether or not it is a construction vehicle of another company can be extracted by a patrol worker by determining whether or not a heavy machine such as an excavating machine is loaded at the rear of the vehicle, the appearance of the vehicle, or the like. Further, when discriminating the construction vehicles of other companies, it is preferable to exclude vehicles unrelated to the construction of other companies such as in-house construction vehicles stored in advance. In the present embodiment, the construction vehicle extraction step may be performed using the mobile terminal 5 in the patrol vehicle 3 using the patrol monitoring time.

  When a construction vehicle of another company is extracted in the construction vehicle extraction step, a traveling step is performed in which the traveling vehicle 3 is directed to the area A and monitoring is performed. Here, the patrol vehicle 3 heading for patrol monitoring is not limited to the vehicle of the patrol worker who performed the construction vehicle extraction step, and the nearest patrol vehicle 3 may head for the region A at that time.

  By doing as described above, it is possible to efficiently perform patrol monitoring to a region having a road that has a narrow path like the region A in FIG.
