Description

Technical Field

[0001] The invention relates to the field of vehicle identification in construction tunnels, and in particular to a method for writing labels for heavy vehicles and light vehicles at a tunnel construction site. Background Art

[0002] In existing tunnel construction projects, due to the complex structure of the tunnel and the numerous intersections, in order to give priority to heavy vehicles in the tunnel and avoid traffic congestion in the tunnel, it is necessary to identify the vehicles entering the tunnel as light or heavy vehicles. The existing identification method is to weigh the vehicle at a fixed position and identify the vehicle as light or heavy based on the comparison of the weighing result with the vehicle's rated load. This identification method requires high equipment costs, and the identification process requires the vehicle to stop and wait for the weighing to be completed before the vehicle can leave, resulting in low efficiency. Summary of the invention

[0003] The object of the present invention is to provide a method capable of quickly identifying a vehicle as a light vehicle or a heavy vehicle.

[0004] In order to achieve the above-mentioned purpose, the method for writing heavy vehicle and light vehicle labels at a tunnel construction site provided by the present invention includes identifying vehicles entering the construction site, retrieving the work task information of the vehicle entering the construction site from the control center; identifying the vehicle as a heavy vehicle or a light vehicle according to the work task information, and writing a first label for the vehicle's on-board sensor according to the identification result, the first label includes a heavy vehicle label or a light vehicle label, and the first label is written into the vehicle's on-board sensor in the form of data; after the vehicle arrives at the work site, the vehicle's location information is uploaded to the control center; when the control center detects that the vehicle has left the work site, the control center rewrites a second label for the vehicle's on-board sensor according to the vehicle's work task information, and the second label covers the first label, and the second label includes a heavy vehicle label or a light vehicle label; the priority of the heavy vehicle label is higher than the priority of the light vehicle label.

[0005] It can be seen from the above scheme that according to the distribution of work tasks of vehicles entering the construction site, the loading status of the vehicle can be judged according to the different work contents of the vehicle at various locations and time nodes. When labeling the vehicle as light or heavy, it is only necessary to identify the basic information of the vehicle at each location, and then check the task information corresponding to the vehicle. The light or heavy vehicle label can be written for the vehicle according to the vehicle's location information and the vehicle's work content. Every time the vehicle arrives at the next work location, the old label is covered with a new label. There is no need to weigh the vehicle, which reduces the time required to identify the light or heavy status of the vehicle and improves the vehicle's passage rate.

[0006] According to the above scheme, further, the entrance of the work site and / or the construction site is also provided with a light and heavy vehicle identification device, which identifies the vehicle as a light vehicle or a heavy vehicle; the light and heavy vehicle identification device at the entrance of the construction site writes a third tag for the vehicle-mounted sensor according to the identification result, and the third tag includes a heavy vehicle tag and a light vehicle tag; and / or the light and heavy vehicle identification device at the work site writes a fourth tag for the vehicle-mounted sensor according to the identification result, and the fourth tag includes a heavy vehicle tag and a light vehicle tag.

[0007] According to the above solution, further, the light and heavy vehicle identification device is at least one of a pressure identification device, an image identification device and a laser identification device.

[0008] According to the above scheme, after writing the third tag, the first tag and the third tag are compared; if the first tag and the third tag are consistent, the first tag is retained and the third tag is deleted, or the third tag is retained and the first tag is deleted; if the first tag and the third tag are inconsistent, an abnormal tag is written for the vehicle's on-board sensor, and the on-board sensor feeds back the abnormal tag to the control center, the control center and the driver of the vehicle manually confirm, delete all tags in the on-board sensor, and rewrite the tag for the vehicle according to the confirmation result.

[0009] According to the above scheme, after writing the fourth tag, the second tag and the fourth tag are compared; if the second tag and the fourth tag are consistent, the second tag is retained and the fourth tag is deleted, or the fourth tag is retained and the second tag is deleted; if the second tag and the fourth tag are inconsistent, an abnormal tag is written for the vehicle's on-board sensor, and the on-board sensor feeds back the abnormal tag to the control center, the control center and the driver of the vehicle manually confirm, delete the tag in the on-board sensor, and rewrite the tag for the vehicle according to the confirmation result.

[0010] It can be seen from the above scheme that secondary identification of the light or heavy vehicle status of the vehicle through at least one of the pressure identification device, the image recognition device and the laser identification device can prevent inaccurate identification caused by failure of a single identification method; at the same time, when the vehicle obtains two different labels at the same location, it means that one of the identification methods is wrong. Rewriting the label through manual confirmation can ensure that the vehicle label is consistent with the vehicle status, preventing label errors caused by equipment failure and affecting the vehicle traffic efficiency in the tunnel.

[0011] According to the above scheme, when a vehicle needs priority passage, an expedited tag is written for the vehicle, and the priority of the expedited tag is higher than the priority of the heavy vehicle tag.

[0012] It can be seen from the above scheme that according to the preset rules, heavy vehicles have a higher priority than light vehicles, but in special circumstances some light vehicles need to pass first. At this time, writing expedited tags can ensure that the dispatching system adjusts the traffic rules to ensure that vehicles with expedited tags have priority and ensure work progress.

[0013] According to the above solution, the expedited tag includes a first expedited tag and a second expedited tag, the first expedited tag is written by the control center, and the second expedited tag is written by the driver of the vehicle.

[0014] It can be seen from the above scheme that under normal circumstances, the control center will comprehensively consider the actual situation on site to write expedited tags for expedited vehicles to improve work efficiency. When special circumstances occur, the driver can write expedited tags for the vehicle he is driving. The control center will verify with the expedited driver and arrange the order of passage according to the situation to effectively deal with the occurrence of special circumstances.

[0015] According to the above solution, when multiple vehicles have expedited tags, the control center assigns priorities to the expedited tags of the multiple vehicles.

[0016] It can be seen from the above scheme that when there are too many vehicles with expedited tags written on them, the control center can assign priorities to the expedited tags of multiple vehicles, which can effectively ensure traffic efficiency and prevent congestion. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a flow chart of a method for writing labels for heavy vehicles and light vehicles at a tunnel construction site according to an embodiment of the present invention.

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0019] See also Figure 1 , a method for writing labels for heavy vehicles and light vehicles at a tunnel construction site, first execute step S1, identify the work vehicle entering the construction site, obtain the work task information of the work vehicle, and write the first label for the work vehicle. Specifically, after the work vehicle enters the construction site, the vehicle identification device set at the entrance of the construction site reads the basic information of the work vehicle by identifying the RFID tag on the work vehicle. The identification device at the entrance of the construction site feeds back the read basic information of the vehicle to the control center. The control center retrieves the work task of the work vehicle, and writes a light vehicle label or a heavy vehicle label to the RFID tag of the work vehicle through the vehicle identification device at the entrance of the construction site according to the work task of the work vehicle. For example, the work task of the work vehicle is to transport a truckload of commercial concrete to the first construction site. After the entrance identification device of the construction site identifies and receives the task information, it writes the first label, i.e., the heavy vehicle label, for the work vehicle.

[0020] Then, step S2 is executed, and the construction vehicle is confirmed to be a light vehicle or a heavy vehicle for a second time through the light and heavy vehicle identification device at the entrance of the construction site, and a third label is written for the construction vehicle at the entrance of the construction site. Specifically, a weighing device is provided at the entrance of the construction site. After the working vehicle passes through the weighing device, the weighing device transmits the weighing result to the vehicle identification device, and the vehicle identification device feeds back the weighing result to the control center. The control center retrieves the basic information of the working vehicle, and compares the vehicle's own weight with the weighing result. If the weighing result is greater than the value of the working vehicle's own weight by more than a preset threshold, the working vehicle is determined to be a heavy vehicle, and a heavy vehicle label is written for the working vehicle. Otherwise, a light vehicle label is written for the working vehicle. The weighing device of this embodiment does not need to accurately weigh the weight of the working vehicle, and preferably uses a non-stop weighing device, and does not need to use a high-precision weighing device, saving equipment costs. In some embodiments, the light and heavy vehicle identification device can also use an image recognition device to identify whether the working vehicle is loaded with goods; a laser recognition device can also be used to detect the loading condition in the loading container of the working vehicle to identify whether the working vehicle is loaded with goods, and other recognition devices can also be used to identify the working vehicle.

[0021] Next, step S3 is executed to compare the first tag and the third tag to confirm the real tag of the working vehicle. Specifically, after writing the third tag, the first tag and the third tag are compared; if the first tag and the third tag are consistent, one of the first tag and the third tag is retained; if the first tag and the third tag are inconsistent, an abnormal tag is written to the RFID tag of the vehicle, and the RFID tag of the vehicle feeds back the abnormal tag to the control center through the vehicle identification device at the entrance of the construction site. The control center manually confirms with the driver of the vehicle, deletes all tags in the on-board sensor, and rewrites the heavy vehicle tag or light vehicle tag for the working vehicle according to the real information fed back by the driver of the working vehicle.

[0022] Then, step S4 is executed. After the working vehicle arrives at the working site, a second tag is written for the working vehicle according to the working task information of the working vehicle, and the second tag covers the first tag or the third tag. Specifically, after the working vehicle arrives at the working site, the vehicle identification device set at the working site reads the basic information of the working vehicle by identifying the RFID tag on the working vehicle. The identification device at the working site feeds back the read basic information of the vehicle to the control center. The control center retrieves the working task information of the working vehicle, and writes a light vehicle tag or a heavy vehicle tag to the RFID tag of the working vehicle through the vehicle identification device at the working site according to the working task information of the working site, and deletes the first tag or the third tag previously written by the working vehicle. For example, the working task of the working vehicle is to transport a truckload of commercial concrete to the first working site and the second working site respectively. After the identification device at the first working site identifies and receives the task information, when the working vehicle leaves the first working site and rushes to the second working site, the second tag, i.e., the heavy vehicle tag, is written for the working vehicle. When the working vehicle leaves the second working site, a new second tag, i.e., the light vehicle tag, is written for the working vehicle. If the work task of the working vehicle is to transport a truckload of commercial concrete to the first working site, after the identification device at the first working site identifies and receives the task information, when the working vehicle leaves the first working site, a second tag, i.e., a light vehicle tag, is written to the working vehicle. After the second tag is written, the first tag or the third tag written at the entrance of the construction site is deleted.

[0023] Next, execute step S5, through the light and heavy vehicle identification device at the work site, confirm twice whether the construction vehicle is a light vehicle or a heavy vehicle, and write a fourth label for the construction vehicle at the work site. Specifically, a weighing device is set at the exit of the work site. After the work vehicle passes through the weighing device, the weighing device transmits the weighing result to the vehicle identification device, and the vehicle identification device feeds back the weighing result to the control center. The control center retrieves the basic information of the work vehicle and compares the vehicle's own weight with the weighing result. If the weighing result is greater than the value of the work vehicle's own weight by more than the preset threshold, the work vehicle is determined to be a heavy vehicle, and a heavy vehicle label is written for the work vehicle. Otherwise, a light vehicle label is written for the work vehicle. The weighing device of this embodiment does not need to accurately weigh the weight of the work vehicle. It is preferred to use a non-stop weighing device, and there is no need to use a high-precision weighing device, which saves equipment costs. In some embodiments, the light and heavy vehicle identification device can also use an image recognition device to identify whether the work vehicle is loaded with goods; a laser recognition device can also be used to detect the loading condition in the work vehicle loading container to identify whether the work vehicle is loaded with goods.

[0024] Then, step S6 is executed to compare the second tag with the fourth tag to confirm the real tag of the working vehicle. Specifically, after writing the fourth tag, the second tag and the fourth tag are compared; if the second tag and the fourth tag are consistent, one of the second tag and the fourth tag is retained; if the second tag and the fourth tag are inconsistent, an abnormal tag is written to the RFID tag of the vehicle, and the RFID tag of the vehicle feeds back the abnormal tag to the control center through the vehicle identification device at the working site. The control center manually confirms with the driver of the vehicle, deletes all tags in the on-board sensor, and rewrites the heavy vehicle tag or light vehicle tag for the working vehicle according to the real information fed back by the driver of the working vehicle.

[0025] When a work vehicle needs priority passage, an expedited tag can also be written for the work vehicle. The expedited tag can be written by the control center and / or the driver. The expedited tag has a higher priority than the heavy vehicle tag, and the heavy vehicle tag has a higher priority than the light vehicle tag. The control center uniformly dispatches the passage of work vehicles according to the priority of the tags of the work vehicles. After each work vehicle leaves a tag writing location, only one final real tag is retained. When multiple work vehicles are written with expedited tags, the control center will assign priorities to the expedited tags of multiple work vehicles based on the actual work content of the work vehicles.

[0026] It should be noted that the above are only preferred embodiments of the present invention, but the design concept of the invention is not limited thereto, and any non-substantial modifications made to the present invention using this concept also fall within the protection scope of the present invention.
