Description

Technical Field

[0001] The present invention relates to the technical field of automated terminal transportation and collaborative operations, and particularly to an operation method and system for the corresponding external tractor and gantry crane interaction area of an automated terminal. Background Art

[0002] In an automated terminal, external trailers (referred to as "external tractors" for short) need to perform container loading and unloading operations. Currently, most of these operations adopt the interaction area operation process, and some terminals also adopt limited mixed traffic (external tractors and IGVs drive in the same area at different times). Compared with the terminal's own horizontal transportation equipment, before the gantry crane performs operations on the external tractor (the gantry crane only detects the external tractor directly below), there are a series of problems such as being unable to confirm whether the external tractor has arrived at the operation position, whether the external tractor has taken the wrong position, whether the external tractor that has not started interaction blocks other external tractors that are in interaction, whether the driver falls asleep in the interaction area, and whether the driver plays with the mobile phone and cannot hear the operation instructions, resulting in low operation efficiency in the interaction area.

[0003] For the above reasons, some automated terminals have set up a design scheme applying RFID cards. Through RFID wireless readers, the relative positions of external tractors that have received RFID cards are read. However, the existing design schemes applying RFID cards have the following disadvantages:

[0004] 1) The investment cost is large. For example, to achieve the same accuracy requirements, the deployment of RFID readers is relatively complex and the number is large;

[0005] 2) The positioning accuracy is low. For example, if one RFID reader is installed every 10 meters, the accuracy is 5 meters (1 / 2 of 10 meters), and precise positioning cannot be achieved;

[0006] 3) The positioning stability is low. There is signal occlusion and attenuation for RFID cards, and the communication quality is difficult to guarantee;

[0007] 4) Communication other than position detection cannot be performed.

[0008] In addition, other positioning methods also have various drawbacks. For example, it is difficult to implement (such as UWB cannot block signals), Bluetooth has poor anti-interference ability, WIFI has regional restrictions, is easily interfered with and does not support some foreign mobile phones, and on-site manual communication with the driver consumes manpower and has poor communication efficiency. In the existing interaction area between external tractors and gantry cranes, when the operator cannot accurately grasp the dynamic position of the external tractor, after the gantry crane reaches the operation position, it is only then discovered that the external tractor has not arrived, wasting operation time and requiring re-adjustment of the operation logic, thus affecting the operation efficiency in the interaction area. Summary of the Invention

[0009] In view of this, it is necessary to propose an operation method and system for the interaction area between external trailers and rail-mounted gantry cranes in an automated terminal to address the above-mentioned problems and overcome the drawbacks in the background technology, thereby solving the following technical problems:

[0010] How to optimize the scheduling and interaction operation method between external trailers and rail-mounted gantry cranes in an automated terminal through the terminal operation scheduling system TOS, the rail-mounted gantry crane management system BMS, camera devices, and mobile communication devices, so as to improve the operation efficiency of the automated terminal.

[0011] To achieve the above object, the present invention adopts the following technical solutions:

[0012] The present invention proposes an operation method for the interaction area between external trailers and rail-mounted gantry cranes in an automated terminal, which is applied to an automated terminal. The automated terminal includes a terminal operation scheduling system TOS, a rail-mounted gantry crane management system BMS, a number of mobile communication devices located in external trailers, a number of rail-mounted gantry cranes, and a number of external trailers entering the automated terminal. The mobile communication devices interact with the terminal operation scheduling system TOS. The automated terminal further includes a camera device for photographing the interaction area between external trailers and rail-mounted gantry cranes, a video processing server for processing the video information transmitted back by the camera device, and positioning columns arranged on the corresponding lanes in the interaction area. The terminal operation scheduling system TOS communicates with the video processing server and the rail-mounted gantry crane management system BMS respectively. The operation method includes the following steps executed in sequence:

[0013] Step S1, after the external trailer enters the interaction area, the terminal operation scheduling system TOS prompts the external trailer of the target position in the interaction area through the mobile communication device or a loudspeaker;

[0014] Step S2, the camera device photographs the positioning columns and the external trailer on the corresponding lane, and the video processing server obtains the real-time accurate position and speed of the external trailer by identifying and analyzing the positioning columns and the external trailer, and transmits the real-time accurate position and speed of the external trailer to the terminal operation scheduling system TOS;

[0015] Step S3, the terminal operation scheduling system TOS transmits the real-time accurate position of the external trailer to the rail-mounted gantry crane management system BMS, and notifies the rail-mounted gantry crane management system BMS of the information that the external trailer is ready for operation;

[0016] Step S4, the rail-mounted gantry crane management system BMS controls the designated rail-mounted gantry crane to cooperate with the external trailer under the rail-mounted gantry crane for collaborative operation.

[0017] Further, before S1, the following steps are also included and executed in sequence:

[0018] Step S100, the external trailer driver obtains the route and instruction task of the external trailer going to the designated interaction area from the terminal operation scheduling system TOS through the mobile communication device, then enters the interaction area, and then executes step S200;

[0019] Step S200, when the external trailer meets the operation conditions in the interaction area, the gantry crane management system BMS notifies the terminal scheduling system TOS, and the terminal scheduling system TOS prompts the driver through the mobile communication device: The external trailer is allowed to enter the interaction area, and then step S1 is executed.

[0020] Further, before S100, the following steps are also included and executed in sequence:

[0021] Step S10001, install a camera device on the lamp post in the outermost lane of the interaction area. The detection angle of the camera device is parallel to the positioning column. Align the camera device with the interaction area so that the positioning column is in the middle of the vertical direction of the image. Set the actual position of the leftmost side of the interaction area as (0, 0), and the pixel coordinates corresponding to this actual position are (0, 0); then execute step S10002;

[0022] Step S10002, convert the pixel coordinates obtained by the camera device into actual coordinates according to the distortion coefficient obtained after calibrating the camera device; then execute step S100.

[0023] Further, in step S10001, by setting the virtual pixel area corresponding to the camera device, the camera device can identify the license plate number of the external trailer.

[0024] Further, in S4, the designated gantry crane is an idle gantry crane or a gantry crane that has ended the interaction with the previous external trailer.

[0025] Further, in step S2, the camera device sends the location information of the external trailer to the video processing server for data processing, and the video processing server then sends the location information of the external trailer to the terminal scheduling system TOS, so that the terminal scheduling system TOS obtains the real-time location of the external trailer.

[0026] Further, at least 300 bays are set in the interaction area, and the number of camera devices is at least 20; during the process of the external trailer driving to the task bay, the camera device at the alignment position starts to enable the positioning function, and sends the real-time location of the external trailer recognized by this camera device to the terminal scheduling system TOS through the video processing server; when the actual position of the external trailer recognized by this camera device is less than N1 bays away from the task bay, if there is no task for the available gantry cranes in the current interaction area, the terminal scheduling system TOS sends an instruction to the gantry crane management system BMS, and the gantry crane management system BMS controls the available gantry cranes to go to the task position to wait; if there is no idle gantry crane in the interaction area, the gantry crane management system BMS ignores the scheduling instruction of the terminal scheduling system TOS;

[0027] When the camera device recognizes that the actual position of the externally towed vehicle is less than <N2> bays away from the task bay, the terminal scheduling system TOS sorts the operation tasks according to the arrival information time and sends them to the gantry crane management system BMS. The gantry crane management system BMS adds the externally towed vehicle to the task sequence and dispatches a gantry crane to perform the operation; <N1> is greater than <N2>.

[0028] The present invention further provides an operation system for the interaction area between the externally towed vehicle and the gantry crane in an automated terminal, which is applied to an automated terminal. The operation system includes a terminal scheduling system TOS, a gantry crane management system BMS, several gantry cranes, several externally towed vehicles entering the automated terminal, a mobile communication device located inside the externally towed vehicle, a positioning column for the corresponding lane in the interaction area between the externally towed vehicle and the gantry crane, a camera device for photographing the externally towed vehicle, a video processing server, and a positioning column arranged on the corresponding lane in the interaction area;

[0029] The terminal scheduling system TOS communicates with the video processing server and the gantry crane management system BMS respectively, and the terminal scheduling system TOS interacts with each mobile communication device for information;

[0030] The video processing server is used to determine the execution of the operation task according to the information of the externally towed vehicle of the gantry crane management system BMS, and also processes the information transmitted back by the camera device to obtain the real-time position and real-time speed of the externally towed vehicle, and transmits the arrival situation of the externally towed vehicle and the normal / abnormal state situation of the externally towed vehicle to the terminal scheduling system TOS;

[0031] The terminal scheduling system TOS is used to, after the externally towed vehicle enters the interaction area, prompt the externally towed vehicle of the target position allowed to enter the interaction area through the mobile communication device or a loudspeaker; and is also used to transmit the real-time accurate position of the externally towed vehicle to the gantry crane management system BMS, and notify the gantry crane management system BMS of the information that the externally towed vehicle has the conditions for operation;

[0032] The mobile communication device is used as a communication device for notifying the driver and for manual intervention in case of abnormal behavior;

[0033] The gantry crane management system BMS is used to control the designated gantry crane to cooperate with the externally towed vehicle under the gantry crane for coordinated operation.

[0034] The present invention further provides an operation system for the interaction area between the externally towed vehicle and the gantry crane in an automated terminal, which is applied to an automated terminal. The operation system includes a terminal scheduling system TOS, a gantry crane management system BMS, several gantry cranes, several externally towed vehicles entering the automated terminal, a mobile communication device located inside the externally towed vehicle, a positioning column for the corresponding lane in the interaction area between the externally towed vehicle and the gantry crane, a camera device for photographing the externally towed vehicle, a video processing server for processing the video information transmitted back by the camera device, and a positioning column arranged on the corresponding lane in the interaction area;

[0035] The terminal operation scheduling system TOS communicates with the video processing server and the gantry crane management system BMS respectively, and the terminal operation scheduling system TOS exchanges information with each mobile communication device;

[0036] The terminal operation scheduling system TOS is used to, after the external trailer enters the interaction area, prompt the target position where the external trailer is allowed to enter the interaction area through a mobile communication device or a loudspeaker; the terminal operation scheduling system TOS is also used to determine the execution of operation tasks according to the external trailer information of the gantry crane management system BMS, and also obtain the real-time position and real-time speed of the external trailer from the information transmitted back by the video processing server, so as to obtain the arrival situation of the external trailer and the normal / abnormal state situation of the external trailer;

[0037] The video processing server is used to process the video information transmitted back by the camera device, and is also used to obtain the real-time accurate position and speed of the external trailer by identifying and analyzing the positioning columns and the external trailer, and transmit the real-time accurate position and speed of the external trailer to the terminal operation scheduling system TOS;

[0038] The camera device is used to photograph the positioning columns and the external trailer in the corresponding lane;

[0039] The mobile communication device is used as a communication device for notifying the driver and manually intervening in abnormal behaviors;

[0040] The gantry crane management system BMS is used to control the designated gantry crane to cooperate with the external trailer under the gantry crane for collaborative operations.

[0041] The beneficial effects of the present invention are as follows:

After entering the interactive area, the real-time position of the external trailer is realized by the visual positioning of the camera device (the positioning accuracy is centimeter level), and the principle is as follows:

[0105] Install a camera device on the high pole lamp in the outermost lane of the interaction area. The installation height of the camera device is 18m (adjustable), the visible angle of the camera device is 120°, that is, the horizontal field of view angle HFOV, the resolution is 1920*1080, the detection angle of view is parallel to the identification and positioning column in the interaction area, and the distance between the identification and positioning column and the camera device is 21m. The width per pixel = horizontal distance 21m × tan(HFOV / 2) / resolution 1920 / 2 = 2.32cm / pixel, and the accuracy can reach the centimeter level. Align the camera device with the interaction area so that it is in the exact middle of the vertical direction of the image. The leftmost side of the interaction area is set as the actual position (0, 0), and the corresponding pixel coordinates are (0, 0). Considering image distortion, the camera needs to be calibrated to obtain the distortion coefficient K (K1, K2, K3, K4...). Then the formula for converting pixel coordinates (x, y) to actual coordinates (X, Y) is (x, y) * width per pixel * K + n * (1920 * width per pixel) = (X, Y), where n is the number of the camera device, and the first one is 0; one camera device can monitor an interaction area of about 44 meters. In this area, high and low positioning columns are installed at intervals of 3 meters. The high positioning column is 2 meters, and the low positioning column is 1.5 meters, painted red to assist the camera device in position recognition. The setting of the high and low positioning columns can also be used for the calibration work of the pixel coordinates of the camera device in the early stage, accurately defining the pixel coordinates on the left and right of each positioning column. When the external trailer passes by and blocks the positioning column, the camera device reads the pixel coordinates (x1, y1) of the first positioning column on the left outside the blocked positioning column, and then reads the pixel coordinates (x2, y2) of the first positioning column on the right outside the most blocked positioning column. Convert (x2, y2) - (x1, y1) to the actual coordinates. The X value of this actual coordinate is the current position of the external trailer. By comparing every twelve frames of the image, the current speed of the external trailer can be obtained as (X2 - X1) / 1s, with the unit cm / s; the area monitored by the second camera device is 44 meters - 88 meters, and so on until the entire interaction area is monitored;

[0106] Set a virtual pixel area in the camera device. The camera device identifies the license plate number on the top or the front of the external trailer and sends the position information of the external trailer to the video processing server for data processing. The video processing server then sends the position information of the external trailer to the terminal scheduling system TOS, and the terminal scheduling system TOS can know the real-time position of the external trailer; in the interaction area of up to 360 bays, a total of 25 camera devices are required, and the interval between the camera devices is 44m;

[0107] During the process of towing the vehicle outside to the task quay position, the camera device on the high mast light starts to enable the positioning function, and sends the real-time position to the terminal scheduling system TOS through the video processing server. When the actual position is less than 20 quay positions away from the task quay position, if there is no task for the available gantry crane in the current interaction area, the terminal scheduling system TOS sends an instruction to the gantry crane management system BMS to let the available gantry crane go to the task position and wait; if there is no idle one, the information will be ignored;

[0108] When the actual position is less than 5 quay positions away from the task quay position, the terminal scheduling system TOS sorts the operation tasks according to the arrival information time and sends them to the gantry crane management system BMS. The gantry crane management system BMS adds the towed vehicle outside to the task sequence and sends a gantry crane to perform the operation.

The entire process conducts a full-cycle closed-loop management of the external trailers entering and leaving the interaction area, ensuring the service quality of the interaction area.
