Description

Technical Field

[0001] The present invention relates to the technical field of container dispatching control at an automated container terminal, and in particular to an empty container dispatching control method suitable for picking up containers at a gate of an automated container terminal. Background Art

[0002] In 1993, the world's first automated terminal was put into operation. Since then, with the update and iteration of technology, the fourth generation of automated terminals has been formed, which are fully automated and unmanned from shore loading and unloading to horizontal transportation in the yard. The selection of different technical routes will lead to different operating characteristics of existing automated terminals. When choosing a technical route for newly built or renovated automated terminals, it is necessary to combine the needs of the main local business sources.

[0003] Among them, the container operation type that arrives at the port by ship and leaves the port by ship is often called the water-to-water transshipment type. In order to reduce the conflict between yard loading and unloading operations and gate container picking operations, the terminal with a relatively high proportion of water-to-water transshipment business can set up a special interactive area operation yard to achieve spatial operation separation and improve operation efficiency.

[0004] Regarding picking up empty containers, customers consider that the rate for picking up containers with designated container numbers is high, and generally do not specify container numbers for picking up containers without special needs. Shipping companies handle entrustment to pick up containers from the wharf gate based on local container demand. The entrustment content clearly states the basic information of the container company, container type and size, etc. Since the corresponding storage fee will be charged after the containers are stored at the wharf for more than a certain period of time, the shipping company will require the containers that arrive at the port first to be picked up first, that is, the first-in-first-out principle. For the existing terminal empty container release, the booking information of the external container truck is generally compared with the information of the containers on site, and the container number that meets the conditions is found and given to complete the container release operation. This type of empty container release has no site restrictions, and the time for customers to pick up containers is difficult to predict. Therefore, it is easy to form conflicts between multiple container pick-up and unloading operations and container collection and unloading operations in the yard.

[0005] When empty containers are released at existing terminals, the container pick-up reservation information of the external container truck is generally compared with the container information of all containers on the yard, so that the container can be found in all yards and the container release operation can be completed. Since it is difficult to control the time and quantity type requirements of customers to pick up containers, the operation points of external container trucks are scattered, and more yard operation machinery resources are occupied during peak operation periods, which easily leads to multiple operation conflict points during peak loading and unloading operations or gate pick-up and return operations. Summary of the invention

[0006] In view of this, it is necessary to propose an empty container shipping control method suitable for picking up containers at the gate of an automated container terminal in order to overcome some shortcomings of the above-mentioned background technology and thus solve the technical problem of how to improve the operational efficiency of empty container shipping suitable for picking up containers at the gate of an automated container terminal.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] The present invention proposes an empty container shipping control method applicable to picking up containers at a gate of an automated container terminal, which is applied to an automated container terminal. The automated container terminal is provided with a first-level gate for collecting license plate information, a second-level gate for verifying license plate information and reservation entrustment information, a third-level gate, a terminal management system TOS, a yard, a rail crane arranged in the yard, a yard interaction area for loading and unloading external container trucks in the yard, and a container box number recognition system OCR arranged at the rail crane. The control method comprises the following steps executed in sequence:

[0009] Step 1: Adjust the empty container shipping plan according to the empty container operation situation in the interactive area;

[0010] Step 2: When the customer's empty container pick-up entrustment information meets the requirements, the external container truck is allowed to make an appointment to enter the gate to pick up the container;

[0011] Step 3: When the external container truck enters the gate within the reservation time period and meets the reservation conditions, the external container truck is allowed to enter the second-level gate;

[0012] Step 4: After the external container truck enters the second-level gate, the TOS system matches the qualified empty containers through an empty container shipping plan and a pile of container search rules, and generates a container pick-up task or a container transfer task;

[0013] Step 5: Push the corresponding work position to the external truck driver, and then the external truck enters the yard interaction area according to the designated work position and waits for work;

[0014] Step 6: The rail crane performs the unloading action according to the unloading task obtained from the TOS system;

[0015] Step 7: The TOS system confirms that the unloading task of the external container truck is completed. When the external container truck leaves the gate, the container number recognition system OCR compares the task container number with the actual container number. If the comparison meets the release conditions, it will be released.

[0016] Furthermore, the vehicle type passing through the sea-side operation lane of the yard interaction area is IGV, and different types of vehicles are driving in the lanes on both sides of the yard; in step one, the empty container operation status of the interaction area is obtained on the system interface set in TOS, and the empty container operation status of the interaction area includes: statistics on the current empty container pick-up entrustment, the number of each type of empty container orders processed expressed in the form of a list, and the number of empty containers stored in the interaction area yard.

[0017] Furthermore, in step 1, the empty container shipping plan satisfies the following conditions:

[0018] Condition 1: Display empty containers on site in units of container information and yard shell number;

[0019] Condition 2 allows the adjustment of the shipping order of different types of empty containers. The smaller the order, the higher the priority when searching for containers.

[0020] Furthermore, the automated container terminal is provided with a smart port intelligent service platform IPORT; in step 1, the customer handles the entrustment of picking up empty containers through the smart port intelligent service platform IPORT.

[0021] Furthermore, in the smart port intelligent service platform IPORT, the terminal provides the customer with an IPORT account. After logging in, the customer selects an empty container to place the container. The truck driver enters the entrustment number and license plate number through a mobile network service software platform to make an appointment for the gate entry time. If the appointment time period is exceeded, the appointment will be invalid and a new appointment is required.

[0022] In the smart port intelligent service platform IPORT, credit points are accumulated for the outbound container trucks that make appointments on time. Outbound container trucks with high credit points are given priority in operation after entering the gate.

[0023] Furthermore, in step 4, the container search process in the yard includes the following steps S4.1 to S4.4 executed in sequence:

[0024] Step S4.1, verify and find the empty container according to the empty container pick-up entrustment information handled by the customer;

[0025] Step S4.2, when the foreign container truck passes through the second-level gate, if there is a container in the yard that meets the entrustment conditions filled in by the customer when handling the entrustment, when the container is not in the interactive area or is locked or restricted by the yard, the salesperson will be prompted to intervene and the salesperson will generate a container transfer instruction with one click. At the same time, the terminal management system TOS triggers a message to notify the foreign container truck to go to the buffer area of ​​the automated container terminal to wait for operation;

[0026] Step S4.3, if there is a container that meets the conditions in the interactive area, the external container truck enters the yard operation area of ​​the interactive area;

[0027] Step S4.4, if there is no available container in the yard, the terminal management system TOS triggers a message to notify the external container truck that there is no container available for pick-up in the yard and guide the driver to exit the gate.

[0028] Further, in step 4, the process of using the empty container shipping plan includes the following steps S401 to S403 executed in sequence:

[0029] Step S401, all empty containers are divided into different shipping plan units by the TOS system according to the container company, container size, container type, container classification, whether there is a damage mark, and the category of the yard shell number, and then a shipping plan is generated by one-click operation. The TOS system generates a shipping plan for the empty containers in the interactive area yard according to the number of storage days from large to small, and the shipping plan items in which all empty containers in the shell have been emptied are automatically deleted;

[0030] Step S402, based on the one-click generation of the shipping plan by the TOS system, the following options are executed:

[0031] Option 1, delete or add a shipping plan;

[0032] Option 2, modify the shipping sequence;

[0033] Option 3: set the shipping plan unit to prioritize only some of the box numbers;

[0034] Option 4, select single or multiple box numbers;

[0035] Step S403, the TOS system prioritizes boxes that are earlier in the shipping plan. When the priorities of boxes in the shipping plan are consistent, it randomly selects from multiple boxes with consistent priorities.

[0036] Furthermore, when the spreader of the rail crane on the external container truck lane on the land side of the yard is lowered below the safe height, the spreader movement is remotely controlled by the rail crane driver.

[0037] Furthermore, the automated container terminal is also equipped with a target detection system TDS and a container truck positioning system CPS; the target detection system TDS is used to detect the position of containers and container trucks through 3D laser to achieve precise positioning; the container truck positioning system CPS is used to guide external container truck drivers to quickly and accurately dock and obtain positions based on laser detection; in step 6, the rail crane performs the unloading action according to the unloading task obtained from the TOS system to meet the following conditions:

[0038] Condition 1: The outbound task with the outbound destination being an external container truck matches the outbound truck license plate number recognized by the container number recognition system OCR;

[0039] Condition 2: The target detection system TDS and the container truck positioning system CPS are used to identify and guide external container trucks to accurately align their positions.

[0040] The present invention further proposes an automated container terminal, including a yard, a quay crane, a terminal management system TOS, a yard interaction area for loading and unloading external container trucks, a rail crane and a plurality of IGVs arranged in the yard, an IGV running on the sea side operation lane of the yard, and an external container truck entering the terminal running on the land side operation lane of the yard, applied to the empty container shipping control method applicable to the gate pick-up of an automated container terminal as described in any one of the above items, the automated container terminal also includes:

[0041] The first level gate is used to collect license plate information;

[0042] The second level gate is used to verify the license plate information and reservation entrustment information;

[0043] The third-level gate verifies whether the container number matches the information identified by the first and second-level gates and the TOS task of the terminal management system. If they match, the vehicle is released;

[0044] The container number recognition system OCR is installed on the track crane;

[0045] IPORT, the intelligent service platform of smart ports, is used to serve customers in handling empty container pick-up entrustment;

[0046] The target detection system TDS is used to detect the position of containers and trucks through 3D laser to achieve precise positioning;

[0047] The container truck positioning system CPS is used to guide external container truck drivers to dock quickly and accurately through laser detection.

[0048] The beneficial effects of the present invention are:

[0049] The present invention improves the efficiency of empty container shipment suitable for gate pickup at automated container terminals; the present invention separates the hot spots of yard loading and unloading and gate pickup from the perspective of yard layout and setting, thereby improving the efficiency of empty container pickup at the gate, and the operation is simple, which is convenient for sales staff to learn quickly and easy to use; the present invention also improves the accuracy of the terminal's prediction of future gate operation conditions, so that operation planning can be done in advance and the waiting time for external container trucks can be shortened, thereby improving the efficiency of empty container pickup operations and achieving efficient and accurate gate release.

[0070] Example 1

[0071] like Figure 1-Figure 3 As shown:

[0072] This embodiment proposes an empty container shipping control method applicable to picking up containers at a gate of an automated container terminal, which is applied to an automated container terminal. The automated container terminal is provided with a first-level gate for collecting license plate information, a second-level gate for verifying license plate information and reservation entrustment information, a third-level gate, a terminal management system TOS, a yard, a rail crane arranged in the yard, a yard interaction area for loading and unloading external container trucks in the yard, and a container box number recognition system OCR arranged at the rail crane. The control method includes the following steps performed in sequence:

[0073] Step 1: Adjust the empty container shipping plan according to the empty container operation situation in the interactive area;

[0074] Step 2: When the customer's empty container pick-up entrustment information meets the requirements, the external container truck is allowed to make an appointment to enter the gate to pick up the container;

[0075] Step 3: When the external container truck enters the gate within the reservation time period and meets the reservation conditions, the external container truck is allowed to enter the second-level gate;

[0076] Step 4: After the external container truck enters the second-level gate, the TOS system matches the qualified empty containers through an empty container shipping plan and a pile of container search rules, and generates a container pick-up task or a container transfer task;

[0077] Step 5: Push the corresponding work position to the external truck driver, and then the external truck enters the yard interaction area according to the designated work position and waits for work;

[0078] Step 6: The rail crane performs the unloading action according to the unloading task obtained from the TOS system;

[0079] Step 7: The TOS system confirms that the unloading task of the external container truck is completed. When the external container truck leaves the gate, the container number recognition system OCR compares the task container number with the actual container number. If the comparison meets the release conditions, it will be released.

[0080] Further optimized, the rail crane is a double-cantilever rail crane.

[0081] Optimally, the vehicle type passing through the sea-side operation lane of the yard interaction area is IGV, and different types of vehicles are driving in the lanes on both sides of the yard; in step one, the empty container operation status of the interaction area is obtained on the system interface set in TOS, and the empty container operation status of the interaction area includes: statistics on the current empty container pick-up entrustment, the number of processed orders of each type of empty containers expressed in the form of a list, and the number of empty containers stored in the interaction area yard.

[0082] Optimally, in step 1, the empty container shipping plan satisfies the following conditions:

[0083] Condition 1: Display empty containers on site in units of container information and yard shell number;

[0084] Condition 2 allows the adjustment of the shipping order of different types of empty containers. The smaller the order, the higher the priority when searching for containers.

[0085] Optimally, the automated container terminal is equipped with a smart port intelligent service platform IPORT; in step one, the customer handles the entrustment of picking up empty containers through the smart port intelligent service platform IPORT.

[0086] Optimally, in the smart port intelligent service platform IPORT, the terminal provides the customer with an IPORT account. After logging in, the customer selects an empty container and places the container. The external container truck driver enters the entrustment number and license plate number through a mobile network service software platform to make an appointment for the gate entry time. If the appointment time period is exceeded, the appointment will be invalid and a new appointment is required.

[0087] Optimally, in the smart port intelligent service platform IPORT, credit points are accumulated for the external container trucks that have made appointments on time. After entering the gate, the external container trucks with high credit points are given priority in operation.

[0088] Optimally, in step 4, the container search process in the yard includes the following steps S4.1 to S4.4 executed in sequence:

[0089] Step S4.1, verify and find the empty container according to the empty container pick-up entrustment information handled by the customer;

[0090] Step S4.2, when the foreign container truck passes through the second-level gate, if there is a container in the yard that meets the entrustment conditions filled in by the customer when handling the entrustment, when the container is not in the interactive area or is locked or restricted by the yard, the salesperson will be prompted to intervene and the salesperson will generate a container transfer instruction with one click. At the same time, the terminal management system TOS triggers a message to notify the foreign container truck to go to the buffer area of ​​the automated container terminal to wait for operation;

[0091] Step S4.3, if there is a container that meets the conditions in the interactive area, the external container truck enters the yard operation area of ​​the interactive area;

[0092] Step S4.4, if there is no available container in the yard, the terminal management system TOS triggers a message to notify the external container truck that there is no container available for pick-up in the yard and guide the driver to exit the gate.

[0093] Optimally, in step 4, the process of using the empty container shipping plan includes steps S401 to S403 executed in the following order:

[0094] Step S401, all empty containers are divided into different shipping plan units by the TOS system according to the container company, container size, container type, container classification, whether there is a damage mark, and the category of the yard shell number, and then a shipping plan is generated by one-click operation. The TOS system generates a shipping plan for the empty containers in the interactive area yard according to the number of storage days from large to small, and the shipping plan items in which all empty containers in the shell have been emptied are automatically deleted;

[0095] Step S402, based on the one-click generation of the shipping plan by the TOS system, the following options are executed:

[0096] Option 1, delete or add a shipping plan;

[0097] Option 2, modify the shipping sequence;

[0098] Option 3: set the shipping plan unit to prioritize only some of the box numbers;

[0099] Option 4, select single or multiple box numbers;

[0100] Step S403, the TOS system prioritizes boxes that are earlier in the shipping plan. When the priorities of boxes in the shipping plan are consistent, it randomly selects from multiple boxes with consistent priorities.

[0101] Specifically, in step S403, when the TOS system receives a container from a foreign container truck entering the gate, there are multiple empty containers that meet the requirements and can be picked up.

[0102] Specifically, in step 4, the empty container shipping plan described in this embodiment is used to adjust the shipping order of empty containers of the same type in the TOS system, and is a module for placing empty containers according to the plan; first, the TOS system will divide all empty containers into different shipping plan units according to the container company, container size, container type, container classification, whether there is a damage mark, and the yard number; the empty container shipping plan described in the present invention, the TOS system interface will display the number of containers, the maximum storage days, the maximum number of containers in the storage day, the number of overdue containers, and whether the yard location is an interactive area yard for each shipping plan unit; regarding overdue containers, the terminal will set free storage days for each company's empty containers based on the agreement with the customer, and containers that exceed the free storage period are overdue containers; the rate for picking up containers by specifying a container number will be higher than that for picking up containers by not specifying a container number. Therefore, regarding empty container shipping, the customer's demand is that containers with longer storage days are shipped first, and when picking up containers by not specifying a container number, external container trucks can take away containers with longer storage periods first.

[0103] Specifically, in step S402, the usage scenario corresponding to the empty container shipping plan described in this embodiment is generally to set a shipping plan when the machinery is under maintenance in turn, giving priority to the empty containers within the operating range of the maintenance machinery two hours later, and the empty containers within the remaining range will be reserved for priority shipment when the machinery is under maintenance, so as to avoid interruptions in customer container pick-up due to machinery maintenance.

[0104] Optimally, when the spreader of the rail crane on the landside container truck lane of the yard is lowered below the safe height, the spreader movement is remotely controlled by the rail crane driver.

[0105] Optimally, the automated container terminal is also equipped with a target detection system TDS and a container truck positioning system CPS; the target detection system TDS is used to detect the position of containers and container trucks through 3D laser to achieve precise positioning; the container truck positioning system CPS is used to guide the external container truck driver to quickly and accurately dock and obtain the position based on laser detection; in step six, the rail crane performs the unloading action according to the unloading task obtained from the TOS system to meet the following conditions:

[0106] Condition 1: The outbound task with the outbound destination being an external container truck matches the outbound truck license plate number recognized by the container number recognition system OCR;

[0107] Condition 2: The target detection system TDS and the container truck positioning system CPS are used to identify and guide external container trucks to accurately align their positions.

[0108] This embodiment further proposes an automated container terminal, including a yard, a quay crane, a terminal management system TOS, a yard interaction area for loading and unloading external container trucks, a rail crane and multiple IGVs arranged in the yard, an IGV running on the sea side operation lane of the yard, and an external container truck entering the terminal running on the land side operation lane of the yard, which is applied to the empty container shipping control method applicable to the gate pick-up of an automated container terminal as described in any of the above technical solutions, and the automated container terminal also includes:

[0109] The first level gate is used to collect license plate information;

[0110] The second level gate is used to verify the license plate information and reservation entrustment information;

[0111] The third-level gate verifies whether the container number matches the information identified by the first and second-level gates and the TOS task of the terminal management system. If they match, the vehicle is released;

[0112] The container number recognition system OCR is installed on the track crane;

[0113] IPORT, the intelligent service platform of smart ports, is used to serve customers in handling empty container pick-up entrustment;

[0114] The target detection system TDS is used to detect the position of containers and trucks through 3D laser to achieve precise positioning;

[0115] The container truck positioning system CPS is used to guide external container truck drivers to dock quickly and accurately through laser detection.

[0116] For further optimization, the automated container terminal is also equipped with a rail crane equipment control system ECS, a target detection system TDS (the target detection system TDS detects the position of containers and trucks based on 3D laser technology to achieve precise positioning, referred to as the TDS system), a truck positioning system CPS (the truck positioning system CPS is based on laser detection to guide external truck drivers to quickly and accurately dock and obtain positions, referred to as the CPS system) and a smart port intelligent service platform (referred to as the IPORT system); the control method of this embodiment involves an explicit rule empty container shipping plan adjusted by the salesperson and an automatic container search verification in the implicit rule yard that is not in the foreground, as well as some functions that can be manually intervened, to achieve an efficient and accurate method of releasing containers at the gate.

[0117] The empty container shipping control method applicable to the automated container terminal gate pick-up of this embodiment has the following advantages:

[0118] The control method of this embodiment sets up interactive operation yard areas for automated unmanned vehicles and external container trucks through yard layout planning, combines relevant hardware equipment such as rail cranes and software systems, establishes a credit accumulation system for external container truck reservation operations, encourages external container trucks to arrive at the port for operations at the scheduled time, creates an empty container shipping plan, and enables empty containers to be released in a planned manner according to the distribution units of the operation site and the number of storage days, thereby meeting customer needs and ensuring orderly container pickup at the gate;

[0119] The empty container shipping plan of the control method of this embodiment is simple to operate and easy to understand, which is convenient for sales staff to learn quickly and easy to use;

[0120] Based on the research of the existing methods of releasing containers at gates, this embodiment proposes an empty container shipping control method suitable for picking up containers at gates of automated container terminals. In combination with the empty container shipping plan, all empty containers that meet the conditions are listed through global rules and matching rules, and the conditions related to the operation are listed to form a sorting strategy and weighting rules for empty containers that meet the release rules under the same conditions, so as to provide the best choice that meets customer requirements and terminal operation conditions.

[0121] The control method of this embodiment proposes a one-key generation of a box transfer plan in terms of empty box transfer in the automated operation area and the interactive operation area, which reduces the number of box transfer operation steps for the salesperson. After the gate appointment box transfer is completed, the TOS system updates the box position and resends the message. The WeChat public account pushes a new message to guide the external container truck to enter the third-level gate for operation;

[0122] The control method of this embodiment can enable the TOS system to have a manual container change function when the automatic container search result is not applicable due to sudden factors on site, such as mechanical failure, after the automatic container search is completed, allowing the salesperson to enter the container number to change the operation container number, and determine whether the TOS system verifies that the container number meets the container pick-up requirements. If yes, the external container truck container pick-up instruction is updated, the message is updated, and the driver is reminded to go to the new location to wait for the operation. If it does not meet the container pick-up requirements, a failure prompt is given and the container change is not allowed;

[0123] The control method of this embodiment aims at the problem of unpredictable operation of external container trucks, and establishes a reservation credit system. The external container trucks that enter the gate within the reservation time period accumulate credit points after each operation, and encourage the external container trucks to develop the habit of making reservations in advance and entering the gate on time, so as to improve the accuracy of the terminal's prediction of future gate operation conditions, so as to make operation plans in advance, shorten the waiting time of external container trucks, and improve the efficiency of empty container pickup operations;

[0124] The control method of this embodiment, through the perspective of yard layout and yard setting, concentrates the emptying operation in the yard set up at the terminal that allows external container truck operations, thereby reducing the conflict points between loading and unloading operations in the whole yard and container picking operations at the gate;

[0125] The control method of this embodiment adds an empty container shipping plan, pre-sets a section, adds a priority setting for storage days, combines the operation location of the container, the container owner information, the container classification and the container type and size information, divides the components into different units, and manually selects the unit sorting;

[0126] The control method of this embodiment separates the hot spots of yard loading and unloading and gate container picking operations from the perspective of yard layout and setting, thereby improving the efficiency of gate empty container picking and reducing the conflict between gate operations and yard container collection and unloading from the source.

[0127] Example 2

[0128] Embodiment 2 is a further optimized design of Embodiment 1;

[0129] like Figure 1 As shown:

[0130] In the process of applying the empty container shipment control method for picking up containers at the gate of an automated container terminal of the present embodiment, in the field map define definition of the TOS system, the TOS system can select the machine type and trailer type allowed to operate in each yard. The machine types include rail cranes and mobile machines, such as reach loaders, stackers, etc. The trailer types include IGV, terminal-owned container trucks (hereinafter referred to as container trucks), and external container trucks (hereinafter referred to as external container trucks); if a certain trailer type is not selected, the corresponding operation instruction will be blocked by the scheduling system and the operation will not be allowed. For example, the trailer type of the non-interactive area operation yard does not select an external container truck. When an external container truck enters the gate to pick up containers, and matches the containers of this type of yard, the TOS system will send a message to instruct the external container truck driver to wait in the buffer zone, prompt the salesperson to intervene and handle, and move the container with one click; through the definition of define, the yard where the external container truck is allowed to operate can be set, and the external container truck can be arranged to pick up containers at the designated yard in a planned manner to reduce the impact on the overall operation of the yard.

[0131] In the process of applying the empty container shipment control method applicable to the automated container terminal gate pickup of the present embodiment, in step 2, an appointment is made to pick up the container at the gate through the IPORT system. The IPORT system is an intelligent network platform independently developed and built, and has functions including but not limited to processing orders, importing import information, and querying container information; the IPORT system and the TOS system have an information interaction interface, which is convenient for customers to query the on-site container information in real time, handle the container pickup or return entrustment, and import import information.

[0132] like Figure 2As shown, the interactive area yard is set at the landmost side of the horizontally arranged yard, away from the loading and unloading front, close to the entrance and exit gate, with the sea side as the IGV operation lane and the land side as the external container truck operation lane. The rail crane is fully automated on the IGV side and remotely semi-automated on the external container truck side, that is, the spreader is lowered below the safe height, a prompt pops up on the remote operating console, the rail crane driver takes over the operating console to complete the instruction, the ECS system feedbacks the result of the container release, and the TOS system confirms that the instruction is completed; the location of the container picked up by the external container truck is not in the interactive area, the TOS system sends a message, and the WeChat public account pushes a message to the external container truck driver to guide him to wait in the buffer zone. The salesperson can generate the interactive area box transfer with one click according to the abnormal prompt of the gate entry; the interactive area box transfer instruction is sent, the IGV receives the task, the box transfer is completed, the box position is updated to the interactive area, the TOS system updates the message, and the WeChat public account pushes a message to guide the external container truck three-level gate to enter the interactive area operation position; as shown Figure 3 As shown in the figure, when the external container truck arrives at the working position, the TDS system and the CPS system simultaneously confirm that the external container truck has arrived at the working position, the rail crane automatically grabs the container, places the container on the external container truck, and the unloaded crane is lifted to above the safe height, and the task is completed; after the customer makes an appointment to pick up empty containers according to the number of containers, when the trailer enters the gate, the TOS system is required to automatically give the best container number that meets the conditions.

[0133] like Figure 2 As shown, the automatic box search verification rules involved in this embodiment are divided into global rules and matching rules;

[0134] Global rules include rules 1.0 to 5.0:

[0135] Rule 1.0: Find the boxes in the CFS area that have been reported and applied for return;

[0136] Rule 2.0: Find the boxes in the box repair area that have been reported and applied for return;

[0137] Rule 3.0 excludes areas where luggage cannot be picked up as specified in the site control;

[0161] Rule 21) Match the business verification mark;

[0162] Rule 22) Match the inspection mark 1 for strict match, 0 for no judgment.

[0163] Under the box search verification rules, there may be multiple empty boxes that meet the conditions and can be pre-collected, so a sorting strategy and weight rule can be added to select the best option among the boxes that meet the conditions according to actual business needs. When there are multiple best options, one of them is randomly selected.

[0164] The sorting strategies include strategy 1.0 - strategy 20.0:

[0165] Strategy 1.0, BRU_PO_SBUC is sorted by whether it is a special site identification; CY_CLASS = SY;

[0166] Strategy 2.0, BRU_PO_DAM is sorted by whether it is a damaged box mark;

[0167] Strategy 3.0, BRU_PO_OPP is prioritized by the empty container shipping plan, which is set by the salesperson based on daily operations;

[0168] Strategy 4.0, BRU_PO_ASD is sorted by the average storage days within the same bay;

[0176] Strategy 12.0, the second box to be picked up by BRU_PO_2SB is in the same area and same shell as the first box;

[0177] Strategy 13.0, BRU_PO_2BQ The distance between the first and second boxes to be picked up (in number);

[0178] Strategy 14.0, whether BRU_PO_EOP has an empty box exit plan;

[0179] Strategy 15.0, whether BRU_PO_EAP has a mechanical area plan;

[0180] Strategy 16.0, BRU_PO_AEC field area currently has active machinery;

[0181] Strategy 17.0, the current number of machines in the BRU_PO_AEQ field;

[0182] Strategy 18.0, the current number of instructions for BRU_PO_EMI has exceeded the maximum number of instructions in the field, and 20 and 40 feet need to be considered;

[0183] Strategy 19.0, distance between BRU_PO_BUE box and yard machinery (in number);

[0184] Strategy 20.0, BRU_PO_PV weight value.

[0185] The control method of this embodiment can set the weight strategy through the TOS system strategy setting function. The system can filter the top priority boxes by setting the weight value. Each box will calculate a penalty value. The smaller the value, the higher the priority.

[0186] The control method of this embodiment involves weight rules including rule 01)-rule 017):

[0187] Rule 01) BRU_PV_SHFIT weight - number of overturned boxes;

[0188] Rule 02) BRU_PV_EFD weight - whether the storage period has been exceeded;

[0189] Rule 03) BRU_PV_EDS weight - number of days exceeding the storage period;

[0190] Rule 04) BRU_PV_SDS weight - storage days;

[0191] Rule 05) BRU_PV_2SK Weight - The second box to be picked up is in the same field as the first box;

[0192] Rule 06) BRU_PV_2SB Weight - The second box to be picked up is in the same area and same shell as the first box;

[0193] Rule 07) BRU_PV_2BQ weight - the distance between the first and second bins to be picked up (in numpy);

[0194] Rule 08) BRU_PV_EOP weight - whether there is an empty container exit plan;

[0195] Rule 09) BRU_PV_OPP weight - priority of empty container exit plan;

[0196] Rule 010) BRU_PV_EAP Weight - Is there a mechanical area plan?

[0197] Rule 011) BRU_PV_AEC Weight - The field currently has active machinery;

[0198] Rule 012) BRU_PV_AEQ weight - the current number of machines in the field;

[0199] Rule 013) BRU_PV_ATQ Weight - Current number of trailers in the yard;

[0200] Rule 014) BRU_PV_AIQ weight - current number of instructions in the field;

[0201] Rule 015) BRU_PV_EMT Weight - Current Instruction Number The current number of trailers exceeds the maximum number of trailers in the yard;

[0202] Rule 016) BRU_PV_EMI Weight - Current Order Number The current number of trailers has exceeded the maximum number of orders in the yard;

[0203] Rule 017) BRU_PV_BUE Weight - Distance between the bin and yard machinery (in bails).

[0204] Specifically, the empty container shipping priority set in the empty container shipping plan is applied in the sorting strategy of the container search verification rule. The manual container replacement process is a manual intervention option set by the system when the empty container shipping priority is not applicable due to other operational factors after the empty container shipping priority takes effect.

[0205] The empty container shipping plan classifies the empty containers on site according to the container information, and the classification is based on the container type (master) information, container size, container classification, whether there is a damage mark, and the yard position. That is, the containers with the same fields mentioned in the classification basis will be included in the same classification item. Generally, the empty container reservation entrustment that does not specify the container number will require the terminal to release the container based on the container type (master), container size, container classification, and whether there is a damage mark. The empty container shipping plan adds the yard position information to the classification basis, so the presentation effect of each classification item will display the classification basis field. At the same time, the maximum storage days, the maximum storage days, the overdue container quantity, and the number of containers in each group of empty containers will be added to the display items. When selecting the shipping order, the business personnel only need to search by container company and container size, and give priority to the storage days. At the same time, the empty container shipping order can be adjusted in combination with the yard operation situation; for example, if a certain position has a maintenance plan tomorrow and needs to clear the inner container, the business personnel can adjust the priority shipment of this container to reduce the number of containers moved before maintenance and save yard resources.

[0206] Example 3

[0207] Embodiment 3 is a further optimization and improvement based on embodiment 1;

[0208] like Figure 1 As shown:

[0209] In step 2, one of the reservation conditions is the driver's credit score. The accumulated credit score is set after the operation is completed. When multiple external container trucks meet the container pickup conditions and are waiting to enter the gate, due to the limit on the number of instructions set in advance in the port area (generally, the number of instructions is set according to the number of rail cranes that can be operated in the yard, and the ratio is about 8 instructions for one rail crane); external container trucks that exceed the instruction number limit need to wait in the buffer zone. At this time, trailers with high credit scores will be given priority to be dispatched to the operation area after the number of operation instructions drops to meet the dispatch demand; when multiple external container trucks meet the conditions for entering the operation area, the credit score will be added to the weight condition for calculating the task priority of the scheduling system. A high credit score is conducive to the priority of sending the task to the rail crane for completion.

[0210] Credit score accumulation rules: calculate the difference between the reservation time of the external container truck and the actual time of entering the first-level gate, in minutes. If the time difference is greater than or equal to 0 and less than or equal to 30, add 2 points; if it is greater than 30 and less than or equal to 60, add 1 point; if it is greater than 60 and less than or equal to 75, add -1 point; if it is greater than 75 and less than or equal to 90, add -2 points; if it is greater than 90, add -3 points. For new external container trucks with no operation records, the operation credit score is calculated by the average credit score of the operating vehicles in the three days before the operation day when calculating the gate entry sequence and operation sequence (the value here can be observed and adjusted in actual application).

[0211] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
