[0033] Specifically, in this embodiment, the integrated information platform for rail-water transport is an information platform designed and planned based on a new iron-water transfer mode of rack-rail tractor docking and container truck-ship direct pickup. The rack-rail tractor is specially developed and designed for container operations in the rail-water transport scenario. While reducing the frequent movement of the quay crane, the rack-rail vehicle pulls the railway vehicle formation and automatically positions the container to achieve accurate loading and unloading of the container on the railway vehicle. The new mode of direct pickup of the railway vehicle and ship for rail-water transport is based on the current status of the port's existing water container loading and unloading operations, and transforms the traditional water-rail docking operation process, omitting the cumbersome intermediate links, and realizing direct loading and unloading from the quay crane to the railway truck through the rack-rail tractor and the rail-water transport information platform, effectively improving the port's operating efficiency. The integrated information platform for rail-water transport manages the rack-rail vehicle, quay crane, video system, gantry recognition system, and signal light control system under the platform, and conducts real-time and accurate control of the vehicle-ship docking operation throughout the process.

[0034] Combination Figure 2 As shown in the figure, the overall architecture of the integrated information platform for rail-water transport is divided into two layers: field layer and platform layer according to the functional logic hierarchy. Each functional layer is independent and interrelated.

[0035] On-site layer: refers to the operation site of the pier terminal. Based on the existing docking equipment and operating objects such as quay cranes, railway vehicles, and containers, a new type of automated docking equipment, the rack-and-rail tractor, is developed to interact closely with the quay crane to achieve efficient container-railway vehicle docking. At the same time, in order to cooperate with the safe docking of railway shunting locomotives and the exchange of information between the railway and the port, special facilities such as gantry identification and special docking signal lights are added to achieve safe operation control and lay the foundation for the realization of unmanned automated operation terminals in the future.

[0036] Platform layer: Through on-site wired or wireless networking, the control center can achieve information connection with the trestle operation site. In the control center, the rack rail vehicle operation monitoring system and the iron-water combined transport operation information system can realize full-process monitoring of various working conditions (data, video) of the on-site rack rail vehicle operation, and ensure efficient management of the seamless connection between the port and the railway under the premise of ensuring the safety of the operation. At the same time, combined with the intelligent identification system on the on-site gantry, the railway vehicles and containers on the vehicles entering and leaving the trestle can be automatically scanned, and the vehicle number, container number and other information can be identified, and relevant information can be processed, such as the binding of vehicle number and container number, etc., and data services can be provided to the outside through a dedicated data interface, realizing data intercommunication among various informatization systems and improving the data accuracy and efficiency of container operations.

[0037] Among them, the control center generally includes the port dispatching room terminal, the multimodal transport department terminal and the railway station terminal, as well as the rack rail car data server, video server, video monitoring workstation and rack rail car monitoring workstation.

[0038] For the network structure of the integrated information platform for railway-water transport, according to the two-layer structure of the overall planning scheme, the project site network needs to be planned as a whole to ensure the independent operation of each subsystem and effectively ensure the security of the system. For the trestle site, it is necessary to implement the site-level local area networking according to the technical requirements, the gantry identification system forms its own sub-network, and the rack rail vehicle operation monitoring system forms its own sub-network. The two need to form a remote local area network with the remote control center to ensure the data security of the private network.

[0039] Among them, the rack rail vehicle operation monitoring system subnetwork includes the following functions:

[0040] (1) Rack rail vehicle monitoring: positioning, speed, direction, collision avoidance and control, etc.

[0041] (2) Quay crane monitoring: The quay crane is positioned through the quay crane trolley positioning, the meter wheel encoder and the pre-buried magnetic nails in the ground.

[0042] (3) Remote control: forward, backward and stop.

[0043] (4) Traffic light monitoring: Collect the status of each traffic light and control the traffic light according to the operating conditions.

[0044] (5) Video surveillance: driving safety video surveillance, loading and unloading site video surveillance, and road crossing video surveillance.

[0045] Combination Figure 3 As shown, the rack rail vehicle operation monitoring system includes a data acquisition module, a data processing module and a data display module.

[0046] Data acquisition: Through the customized data acquisition driver module and data interface module, the data uploaded by the trestle on-site operation equipment and the locomotive and container information provided by the gantry system are received. The trestle operation site covers rack rail vehicles, quay cranes, video surveillance and gantry systems, signal light systems and other facilities. Data transmission is carried out through the on-site wired or wireless LAN.

[0047] Data processing: Data services are provided through customized data processing and service modules. In addition to completing basic data analysis, calculation, storage and call, control management and data service business are also realized. In order to realize the docking and coordinated operation of the rack rail vehicle and the quay crane, the data processing part calculates the docking position of the rack rail vehicle through the collected position data of the rack rail vehicle and the quay crane, and then the data collection part transmits the docking position data to the rack rail vehicle for execution.

[0048] Data presentation: The system business functions of the software are realized through various customized interactive user interfaces. Through the rack rail vehicle operation monitoring system client, the various working conditions (data, video) of the rack rail vehicle operation on site are monitored throughout the process, ensuring the safety of the operation and the efficient management of the seamless connection between the port and the railway.

[0049] The rack rail vehicle operation monitoring system includes the following business functions:

[0050] (1) Operation monitoring

[0051] The rack rail vehicle operation monitoring realizes real-time operation diagram, vehicle management and equipment operation information display.

[0052] The operation diagram shows the location and working status of equipment systems such as rack rail cars, vehicles, quay cranes, signal lights, gantries, cameras, etc., and also marks construction facilities such as rack rails, stops, machine nests, docking points, and berth areas.

[0053] The vehicle management displays the marshaling of rack rail cars and vehicles, including the actual number of marshaling, vehicle number, vehicle model and length; provides docking position adjustment function, and the platform transmits docking position adjustment information to the rack rail car; and displays the container loading and unloading status information of the vehicle.

[0054] Equipment operation information includes the main operating parameter information of the rack car, quay crane, gantry and signal light.

[0055] (2) Video surveillance

[0056] Provides real-time browsing of operation videos and playback of historical videos. You can take screenshots and record videos in real time, and display pictures / record playback in a specified window.

[0057] (3) Historical data

[0058] The system can query the historical data of equipment operation information and provide data display in the form of historical data curves and data lists.

[0059] (4) Alarm query

[0060] The system can browse detailed real-time alarm information and query historical alarm data.

[0061] In addition, the alarm module of the rack rail vehicle operation monitoring system has rich control and management functions, providing a guarantee for the safe construction of rack rail vehicle on-site operations.

[0062] Multiple levels of alarm thresholds can be defined, and when the status data of the device reaches the preset threshold, the alarm of that level will be automatically triggered.

[0063] The types of alarms that can be defined include: limit value alarm, system alarm when exceeding the preset value; fixed value alarm, system alarm when reaching the preset value; deviation alarm: system alarm when deviating from the preset value within a certain range; change rate alarm: system alarm when the rate of change of the value exceeds the preset value.

[0064] The system alarm module provides a confirmation and recovery mechanism for alarm information. When an alarm message is generated, the operator can respond to the alarm message list on the alarm query page, otherwise the system will continue to remind you that there are unprocessed alarms; after the alarm is eliminated, the system will cancel the unprocessed alarm reminder.

[0065] Main contents of system alarm:

[0066] Equipment failure alarm: system communication failure alarm, rack rail vehicle electrical system failure alarm, quay crane trolley positioning system failure alarm, etc.

[0067] Illegal operation alarm: overspeed alarm, area alarm, etc.

[0068] Environmental factor alarm: obstacle alarm.

[0069] Combination Figure 4 As shown, the iron-water intermodal operation information system includes an intermodal management system and a statistical analysis system. The intermodal management system is used to manage intermodal plans, intermodal processes and intermodal bills of lading, and the statistical analysis system is used to analyze operation efficiency.

[0070] Combination Figure 5 As shown in the figure, the architecture of the iron-water intermodal operation information system includes the presentation layer, business logic processing layer and data layer. The presentation layer includes intermodal plan, intermodal process, intermodal bill of lading, data statistics and other functional modules and presentation interface. The business logic processing layer includes data analysis, security and legality verification, and component interface for external access. The data layer includes database and file access layer (DAO / DAL), File Helper, SQL Helper, Web Service, file management service and database service (SQL server).

[0071] In this embodiment, a new mode of direct vehicle-ship connection for rail-water transport is adopted, and the rack-rail vehicle and other on-site equipment are managed under the rail-water transport comprehensive information platform, and the vehicle-ship connection operation is accurately controlled in real time throughout the entire process. Direct loading and unloading from the quay crane to the railway freight car is achieved through the rack-rail tractor and the rail-water transport information platform, effectively improving the port operation efficiency.

[0072] Optionally, the work site equipment includes a quay crane, a rack rail car, a vehicle to be operated and a container; the data acquisition module is used to collect the position of the quay crane, the position of the rack rail car, the distance between the vehicle to be operated and the rack rail car, the length of the vehicle to be operated and the placement position of the container; the data processing module is used to determine the docking point of the rack rail car based on the position of the quay crane, the position of the rack rail car, the distance between the vehicle to be operated and the rack rail car, the length of the vehicle to be operated and the placement position of the container.

[0073] Specifically, in this embodiment, during docking positioning, the rack rail vehicle operation monitoring system collects the position of the quay crane trolley, the position of the rack rail tractor, and the container placement position on each vehicle in the marshaling, and calculates the docking position of the rack rail vehicle based on this, and transmits the docking position to the rack rail tractor for execution. The quay crane, rack rail tractor, and truck vehicle are all rail transportation equipment and can only perform one-dimensional movement (forward and backward). The rack rail vehicle shares the track with the truck, and the quay crane track is parallel to the rack rail vehicle. Therefore, all equipment can be regarded as being in a 1-dimensional coordinate system. Any point on the track can be defined as the coordinate origin. For the convenience of calculation, the end of the rack rail vehicle track is generally selected as the origin.

[0074] There are two types of containers commonly used by railways and waterways: 20-foot and 40-foot. Ordinary railway freight cars can generally load two 20-foot containers or one 40-foot container. Depending on the specifications of the loaded containers, the docking positions of railway freight cars will vary. Therefore, the system must obtain the container loading position information of each vehicle to correctly calculate the docking position.

[0075] There are several ways to obtain the loading location information:

[0076] (1) The relevant railway stations can upload the container loading location information of train vehicles to the integrated information platform for rail-water transport through terminals, and the platform will push the information to the port multimodal transport department, dispatching and other departments.

[0077] (2) When the train passes the gantry identification system before entering the port, the container vehicle number identification system of the gantry can scan the train to obtain the container loading position information of each vehicle, and then upload it to the integrated information platform for rail-water transport.

[0078] (3) During docking operations, the quay crane driver shall inform the dispatcher of the placement of the containers to be loaded or unloaded on the vehicle based on the operation plan and the status of the operating vehicle.

[0079] Combination Figure 6 As shown, when calculating the docking position, the length data of each vehicle in the marshaling group is obtained through the gantry system, and then the distance data of the center of each vehicle relative to the rack rail vehicle is calculated respectively, and the position data of the rack rail vehicle and the designated quay crane are obtained in real time. The quay crane driver notifies the placement of the container to be loaded and unloaded on the vehicle, such as: 40 feet / 20 feet front (left) / 20 feet back (right), and the operation monitoring operator selects the corresponding docking position adjustment button on the system operation monitoring interface according to the notification.

[0080] Calculate the docking point, the docking point position = designated quay crane position - rack rail vehicle position + distance from the vehicle to be operated to the rack rail vehicle + K*(vehicle length / 4), the K value is determined by the docking position adjustment button selected by the operation monitoring operator. When the container is placed at 40 feet, 20 feet before (left) and 20 feet after (right), the corresponding K values ​​are 0, -1 and 1 respectively.

[0081] The system transmits the location of the docking point to the rack rail vehicle for execution. After the rack rail vehicle arrives at the docking point, it will feedback the arrival signal. The system will automatically locate the next vehicle as the vehicle to be operated according to the marshaling sequence.

[0082] When controlling the docking position, the platform obtains the marshaling data collected by the gantry identification system, and calculates the target position where the rack rail vehicle needs to run according to the input container loading and unloading requirements, and transmits it to the rack rail vehicle electrical system for execution. The rack rail vehicle receives the task and can run to the target position after confirmation.

[0083] In this embodiment, the docking point of the rack rail car is determined according to the position of the quay crane, the position of the rack rail car, the distance from the vehicle to be operated to the rack rail car, the length of the vehicle to be operated and the placement of the container, so as to achieve precise control of the docking and effectively improve the port operation efficiency.

[0084] Optionally, the work site equipment further includes a signal light, and the rack rail vehicle operation monitoring system is used to control the operating state of the signal light according to the position of the rack rail vehicle.

[0085] Specifically, in this embodiment, in order to ensure the safety of the docking operation and avoid collision accidents between the train and the rack rail car at the dock, the integrated information platform for rail-water transport needs to perform interlocking control on the signal lights set on the dock trestle pull-out line.

[0086] For example, when there is no docking task, the rack car stops at the trestle machine nest, the signal light is blue, and the train is prohibited from entering the dock. As long as the rack car is not in a safe parking position, the signal light is blue. After receiving the docking task, the rack car arrives at the safe parking position and the signal light is white. The train can enter the dock when it sees the white light.

[0087] The control principle is as follows:

[0088] The signal light control system is mainly composed of the rack rail vehicle position detection device (beacon), the signal light electrical control interface, the signal light system controller of the information platform and the lighting control relay.

[0089] The position detection device can adopt a mechanical limit switch to detect whether the rack car is in place through the opening and closing state of the contact, and the contact signal is connected to the signal light system controller.

[0090] The signal light electrical control interface includes the lighting power supply interface and alarm output signal of the signal light lighting unit. The lighting power supply is provided by the signal platform lighting control relay, and the alarm output signal is connected to the input module of the signal light system controller.

[0091] The signal light system controller collects the signals from the rack rail vehicle position detection device and the signal light alarm signal and uploads them to the rack rail vehicle operation monitoring system for processing. The operation monitoring system transmits the lighting command to the signal light system controller according to the signal light control requirements, and the controller drives the lighting control relay to light up the signal light of the corresponding color.

[0092] In this embodiment, the rack rail car operation monitoring system controls the operation of the signal light according to the position of the rack rail car, thereby realizing control over the rack rail car docking operation, effectively ensuring the safety of the docking operation, and avoiding collision accidents between the train and the rack rail car at the dock.

[0093] Optionally, the quay crane includes a quay crane trolley and a positioning system, the positioning system is communicatively connected to the data acquisition module, an encoder is installed on the meter wheel of the quay crane trolley, and the signal of the encoder is connected to the PLC counter input port of the positioning system.

[0094] Specifically, in this embodiment, most domestic quay crane equipment is a standardized product, and manufacturers generally do not develop data interfaces for external parties. Moreover, most equipment was developed at an early stage and cannot meet the functional requirements of the current iron-water combined transport vehicle-ship direct access. Therefore, it is necessary to upgrade the quay crane equipment to be intelligent and add a positioning system to the quay crane. The positioning system obtains the position of the quay crane trolley and provides the operation information interaction necessary for the docking operation.

[0095] The quay crane trolley positioning system adopts an encoder positioning solution. A trip wheel is added to the quay crane trolley, and an encoder is installed on the trip wheel. The encoder signal is connected to the counter input port of the quay crane trolley positioning system PLC. The travel distance of the quay crane is calculated through the trip wheel diameter and the wheel diameter, thereby obtaining the specific position of the track where the quay crane is located.

[0096] The coordinate data of the quay crane trolley's travel position is uploaded to the comprehensive information platform for rail-water transport.

[0097] In this embodiment, the positioning system is provided to realize the positioning of the quay crane, thereby realizing precise control of docking, and effectively improving the port operation efficiency.

[0098] Optionally, a magnetic proximity switch is installed on the quay crane trolley, and a plurality of correction magnets are arranged on the ground inside the track at a position corresponding to the installation position of the magnetic proximity switch to reduce the error generated by the encoder and the track.

[0099] Specifically, in this embodiment, a magnetic proximity switch is installed at a position about 30 mm from the ground at the bottom end of the quay crane trolley near the inner side of the track. At the same time, a plurality of correction magnets are arranged under the ground on the inner side of the track and parallel to the track (with a spacing of about 10 m, subject to actual conditions) to reduce the error generated by the encoder and the track.

[0100] Among them, when the quay crane trolley is positioned, the running distance is accumulated through the encoder, and the accumulated error is eliminated by using a correction magnet such as a positioning magnetic nail. Other solutions can use laser ranging, global positioning system, differential positioning, linear absolute position optical encoder, RFID tag positioning, Bluetooth positioning, WiFi positioning, ultra-wideband positioning, laser radar and other technologies to position the quay crane trolley.

[0101] In this embodiment, by providing a magnetic proximity switch and a plurality of correction magnets, the error generated by the encoder and the track is reduced, thereby achieving precise control of the docking, and effectively improving the port operation efficiency.

[0102] Optionally, the work site equipment also includes a gantry identification system, which is used to read the electronic tags installed on the locomotive and the freight car through microwave radio frequency to identify the vehicle number information, running direction information and train formation sequence information of the locomotive and the freight car, and use video recognition technology to identify the container number of the container.

[0103] Specifically, in this embodiment, at the trestle site, the gantry identification system uses microwave radio frequency to read the electronic tags installed on the locomotive and freight car, identify the vehicle number information, running direction information and train formation sequence information of the locomotive and freight car, and use video recognition technology to identify the box number and upload it to the control center through the wired network; the rack rail vehicle operation monitoring system monitors the rack rail vehicle and controls the signal light according to the access data of the sensor on the rack rail vehicle body and the data of the quay crane, signal light and video monitoring. The above data and the formation information are uploaded to the rack rail vehicle operation monitoring system, and the rack rail vehicle operation monitoring system calculates the position of each vehicle in the formation through the body length and coupler length data of each vehicle.

[0104] The control center establishes a local area network, and conducts network communication through wired optical fiber and gantry identification system, and through wireless AP and trestle site. Different VLANs are divided for the control center terminal, server and trestle site, and access rules are established to ensure that each local area network can communicate on demand without interfering with each other.

[0105] In addition to RF microwave radio frequency, 3D lidar, 2D laser profile scanning, visual image recognition and processing, passive / active RFID positioning, global positioning system, differential positioning and other technologies can also be used.

[0106] In this embodiment, the gantry identification system reads the vehicle number information of the vehicle tag through RF microwave radio frequency, so that it can identify the vehicle number information, running direction information and train formation sequence information of the locomotive and truck, and use video recognition technology to identify the container number, thereby realizing precise control of docking and effectively improving port operation efficiency.

[0107] Optionally, the rack rail vehicle comprises a rack rail traction vehicle electrical system for acquiring position data, a rotary encoder is mounted on the driving pin wheel of the rack rail vehicle, and the signal of the rotary encoder is connected to the PLC counter input port of the rack rail traction vehicle electrical system.

[0108] Specifically, in this embodiment, during the positioning of the rack tractor, the position data is obtained through the rack tractor electrical system.
