Description

Technical Field

[0001] The present invention relates to the field of automated field crane equipment, and more specifically, to an automated equipment state intelligent perception platform system for automated field cranes of container terminals and having comprehensive remote inspection and state monitoring functions. Background Art

[0002] RTG, commonly known as yard crane, is also called tire-mounted gantry container crane. It is a common and widely used lifting and unloading equipment in container yards. It is also the main vertical transportation equipment in container terminal yards. At present, automation and intelligent technology has been promoted and widely applied in the port field. In the automation upgrading and transformation of yards and the construction of automated yards, the automation level of yard cranes has also been greatly improved and optimized.

[0003] The optimization and promotion of yard automation will bring many advantages to the terminal, such as: it can greatly improve the working environment of yard crane drivers, reduce drivers' fatigue, and comprehensively improve drivers' work quality; because the automatic operation stability of equipment is improved during the yard automation improvement, the more-control-more and less-control-more modes of automated yard cranes can be realized, which can save the company a lot of labor costs in the use of driver resources; the operation and maintenance costs of automated equipment will be reduced, and the equipment operation stability will be improved; yard automation will greatly optimize and improve the density and intensity of operations in the yard, greatly improve the yard's currency rate, and at the same time optimize and improve the accuracy and stability of operations from the task level.

[0004] However, automated equipment also has certain shortcomings, which are more reflected in the difficulty of maintenance. For example: it cannot be shut down for maintenance as frequently as conventional equipment; it is difficult to carry out vehicle inspections; during operation, the driver cannot directly observe abnormal equipment conditions such as abnormal noises and vibrations on site; it is difficult for the driver to perform front-end inspections, etc.

[0005] In order to solve the above problems, especially the online status monitoring during the operation of the equipment, the best solution is to establish a set of equipment detection platform that is independent and compatible with the automated operation, and integrate the pre-operation remote inspection and equipment online status monitoring functions of the comprehensive intelligent monitoring platform, and have scalability and compatibility. The most important thing is that the equipment comprehensive intelligent detection platform will not affect the operation of the equipment, that is, the comprehensive intelligent monitoring platform cannot participate in the equipment control system. This is also the core and difficulty of the establishment of the platform, that is, the integrated architecture design of different network system architectures.

[0006] For automation equipment control systems, the most complex and core part is its independent and stable network system architecture. After the automation equipment transformation is completed, the automation network architecture is difficult to further expand and be compatible. Some related technologies that need to be expanded are difficult to expand and improve due to the barriers of the network architecture. This is also one of the technical difficulties of automation transformation equipment.

[0007] The technical difficulties in the expansion and compatibility of automation networks are mainly reflected in the following aspects: 1. Considering network security, the mutual interference between different networks affects the safety and stability of the automation network and is likely to cause abnormal communication in the original network.

[0008] 2. The mutual influence of different data signals. The control signal bandwidth in the automation network occupies a small amount but has high real-time requirements and is easily interfered.

[0009] 3. Different network planning can easily cause network storms or network communication abnormalities.

[0010] Therefore, for the functional expansion in the operation and maintenance of automated equipment, the compatibility of different network systems is the key technical core. How to achieve both mutual communication and network isolation and shielding is the key to the expansion of automated networks. Summary of the invention

[0011] The technical problem to be solved by the present invention is to overcome the deficiencies in the above-mentioned prior art and provide an automation equipment status intelligent perception platform system for an automation field bridge.

[0012] The present invention is used for an automation equipment state intelligent perception platform system of an automation field bridge, wherein the ARTG control network machine video unit comprises an NVR hard disk recorder 1, a video switch 1, and a streaming media server 1 which are connected in sequence, the video switch is connected to a remote control core switch, the remote control core switch is respectively connected to a remote core controller, a data aggregation switch, a console 1 and a console 2, and the data aggregation switch is respectively connected to a plurality of PLC+aRTGs; The video remote inspection system includes a second NVR hard disk recorder and a second video switch connected in sequence, and a plurality of cameras are respectively connected to the second video switch; The equipment online monitoring system consists of a status detection controller and a status detection aggregation core switch status monitoring sensor connected in sequence; The intelligent perception monitoring platform includes a remote inspection monitoring platform and a core data switch connected in sequence, and the core data switch is connected to a video core controller and a system core controller respectively; The subsystem and automation system isolation interaction unit is composed of a data interaction isolation switch 1, a network interaction and isolation server, and a data interaction isolation switch 2 connected in sequence; The NVR hard disk video recorder 1 is connected to the data interaction isolation switch 1, the video switch 2 is connected to the core data switch, and the core data switch connection status detection aggregation core switch.

[0013] The video remote inspection system includes remote inspection and collection cameras, which are scattered on the field bridge and mainly installed next to the mechanisms that need to be inspected or focused on, such as: trolley track observation, lifting drum, lifting motor and drive mechanism, trolley motor operation mechanism and driver's room internal observation; mainly through the network to aggregate the remote inspection and collection cameras to the video switch and connect to the NVR hard disk recorder for storage. Remote inspection and collection cameras also include those installed around the trolley trolley to monitor tires, installed on the side of the trolley track to observe the trolley track, installed on the trolley platform to observe the lifting and trolley movement status, etc.

[0014] The equipment online monitoring system uses on-site detection sensors to detect and analyze the temperature, vibration and other conditions of the equipment mechanism and transmits them back to the status detection aggregation core switch for subsequent analysis and processing.

[0015] The condition monitoring sensors in the equipment online monitoring system mainly include vibration temperature detection sensors installed on the lifting reduction box and the trolley reduction box.

[0016] The ARTG control network machine video unit and the intelligent perception monitoring platform are independent network system architectures, which can achieve network interaction isolation while performing data interaction with the automation system isolation interaction unit through the subsystem.

[0017] The present invention has the following beneficial effects: The present invention provides a new automation system upgrade and expansion idea and solution, which integrates the independent network system architectures and ensures that they do not affect each other, which can not only meet the data integration, but also have the feasibility of independent operation upgrade and optimization. It does not require too many complex spare parts designs to meet the relevant technical requirements. The present invention can also be used in the mutual integration mode under each independent network system, which has independent and stable operation and takes into account data fusion and aggregation.

[0021] The present invention includes five subsystem network architectures, namely, ARTG control network machine video unit, video remote inspection system, equipment online monitoring system, intelligent perception monitoring platform and subsystem and automation system isolation interaction unit. The following is a detailed description of each part: 1. The core components of the video remote inspection system include: on-site cameras distributed at key inspection locations, video switches, and NVR hard disk recorders.

[0022] The main functions and components of the above devices are as follows: The camera uses an ordinary industrial-grade camera, and the HIKVISION camera, which is widely used in the market, has a deformity correction function. It is mainly responsible for the real-time recording of on-site data and the collection of visual signals.

[0023] The second NVR, HIKVISION DS-8664N-K8, is a large storage device specially used to store camera video data. It is responsible for saving and recording all video signals in real time for streaming media server to call and convert into streaming media files for transmission. At the same time, it has a playback monitoring function, which is also convenient for daily maintenance system follow-up.

[0024] Video switch 2 is H3B brand, S1850-28P, which is mainly responsible for integrating and interactively processing video data and related data of NVR hard disk recorder 2, and is the data link core of the entire video signal interaction. It also manages and interacts with the remote control core switch of the ARTG control network machine video unit through the isolation interaction unit of the subsystem and automation system. And configure VLAN and topology management for each other and each other to ensure smooth data interaction and shorten delay.

[0025] 2. Equipment online monitoring system The equipment online monitoring system consists of a status monitoring controller, a status detection aggregation core switch and a status monitoring sensor connected in sequence. The system structure is basically implemented on a single machine side.

[0026] The status monitoring controller is responsible for analyzing and processing the collected data signals, integrating and centrally transmitting the data back to the status detection aggregation core switch, and transmitting the data back to the intelligent perception monitoring platform.

[0027] 3. Isolation and interaction unit between subsystem and automation system The stored data signals in the NVR hard disk recorder of the ARTG control network video unit are multiplexed into the intelligent perception monitoring platform through the subsystem and automation system isolation interaction unit. The multiplexed data signals are isolated by two data interaction isolation switches, and VLAN network isolation settings are set. Data interaction is carried out through two data interaction isolation switches and network interaction and isolation servers.

[0028] The network interaction and isolation server has a dual network card setting, which connects to two different networks respectively. The two networks have set up independent and secure data access rules respectively. The data in the cache of the server is obtained through secure access rules to achieve mutual data isolation.

[0029] 4. Intelligent Perception Monitoring Platform The intelligent perception monitoring platform includes a remote inspection monitoring platform and a core data switch connected in sequence. The core data switch is connected to the video core controller and the system core controller respectively. All components adopt universal settings, which is conducive to cost control and subsequent operation and maintenance.

[0030] The core data switch is responsible for the interactive aggregation of data and effectively prevents abnormal data transmission. The data mainly comes from three sources: on-site inspection video signals (from the video remote inspection system), video data in the multiplexed automated field bridge system (from the ARTG control network machine video unit), and equipment online monitoring data (equipment online monitoring system). These three parts of data are collected and processed on the stand-alone side of the on-site equipment, and are respectively aggregated and transmitted back. The three data signals are set up with independent physical links in the architecture of the stand-alone side of the site, and are completely independent of each other.

[0031] The intelligent sensing monitoring platform is responsible for displaying data in real time and performing simple data analysis under the coordination of the system core controller to facilitate maintenance personnel to monitor and manage equipment.

[0032] The video core controller is only responsible for aggregating and controlling the video data, mainly for calling and aggregating the equipment remote inspection data (from the video remote inspection system) and the multiplexed automation operation video data (from the ARTG control network machine video unit).

[0033] 5. ARTG control network machine video unit The ARTG control network machine video unit includes an NVR hard disk recorder 1, a video switch 1, a streaming media server 1, a console and the corresponding OAS computer, display computer, and operation controller that constitute its display, which are connected in sequence. The video switch is connected to the remote control core switch, and the remote control core switch is respectively connected to the remote core controller, the data aggregation switch, the console 1 and the console 2, and the data aggregation switch is respectively connected to multiple PLC+aRTGs.

[0034] The video switch is H3B brand, S1850-28P, which is mainly responsible for integrating and interactively processing video data, NVR video hard disk recorder and related data of streaming media, and managing and interacting with the remote control core switch. It also configures VLAN and topology management respectively to ensure smooth data interaction and shorten delay.

[0035] The streaming media server adopts DELL precision3420, which is the video unit of the ARTG control network machine. It has powerful data processing capabilities, ensures the timely transmission and call of video images, and is responsible for managing the data flow of the entire video network. The most important function of the streaming media server is to demodulate the video image through the decoding and shunting of the streaming media data packets and complete the data decoding function, and transmit the video stream data. This streaming media server is the key technical guarantee to ensure the stable and efficient transmission of the video signal to the display.

[0036] The remote core controller uses DELL server components, and its main functions are data interaction control of the overall system, imaging system call allocation, mutual configuration combination of the console and aRTG, corresponding imaging cameras, and processing of the allocation and call mode of some control signals and instructions.

[0037] The console, console video computer, OAS computer and control controller form the console system, which can realize the remote control function of the aRTG assigned to the video unit, and also has the function of assigning the on-site video data to the video unit for imaging transmission on the console screen. The console video computer and OAS computer are both DELL brand computers, which are mainly responsible for the video display in remote operation. The monitor displays the video image in real time for the remote operation driver to monitor during the operation. The console is a customized product, using the Yaskwa brand.

[0038] The working principle of the present invention is briefly described as follows: 1. The present invention includes on-site inspection video signals (from the video remote inspection system), video data in the multiplexed automated field bridge system (from the ARTG control network machine video unit), and equipment online monitoring data (equipment online monitoring system): (1) On-site inspection video signals come from the video remote inspection system The computing logic of the system core controller exchanges data with the video core controller through the core data switch, and the control signal is transmitted from the core data switch to each camera through the video switch. After the data of each camera is aggregated through the single-machine side video data exchange, the video data is returned to the core data switch.

[0039] (2) The video signal in the multiplexing automation field bridge system comes from the ARTG control network machine video unit In addition to the additional video signals, for cost control considerations, the existing automated field bridge video surveillance camera data was partially reused for equipment inspection. The first inspection and operation monitoring are completely separated in time, and equipment operation and equipment inspection cannot be carried out at the same time. In theory, the impact of repeated references is avoided and the quality of network data will not be affected.

[0040] The video signal in the multiplexing automation field bridge system refers to the video playback data on the automation field bridge, that is, the data stored in the NVR hard disk recorder. Although it is not transmitted in real time, it can meet the technical requirements of monitoring and inspection. The data stored in the NVR hard disk recorder and the real-time monitoring data of the operation do not use the same data transmission channel and do not affect each other.

[0041] (3) The video data of the automated field bridge comes from the video unit of the ARTG control network machine The remote core controller in the video unit of the ARTG control network machine is the core control component and the computing center of data and control. Through the scheduling and matching of the remote core controller, the console and the corresponding aRTG are paired to realize the remote control function; at the same time, the console can realize the configuration and control of the console system through the console controller, mainly the coupling of the video computer, OAS computer and console.

[0042] Each console command and aRTG operation are completed by PLC, remote control and local automatic operation of aRTG, forming a PLC configuration form. The configuration on the control side is mainly under the control configuration of the remote core controller, and the PLC distributor and the console controller perform mutual verification to realize the configuration coupling of the remote control console and aRTG. The single-machine operation of aRTG is driven and controlled by the corresponding PLC, while manual control is mainly completed by the PLC in the console.

[0043] (4) Equipment online monitoring data comes from the equipment online monitoring system Equipment online monitoring mainly relies on sensors to detect the equipment's operating conditions, mainly some commonly used equipment operating status feedback signals, such as engine oil signals, battery pack battery power information, etc.

[0044] The equipment online monitoring system processes the sensor data through the detection processor, integrates the data into the TCP / IP industrial network communication mode through the relevant industrial communication protocol, and then transmits it to the core data switch through the data switch. In order to ensure the stable, safe and reliable operation of the automation equipment, the equipment online monitoring system does not intersect with the equipment automation control system, but adopts an independent network deployment.

[0045] 2. The data transmission convergence link of the present invention: The present invention includes the fusion of three parts of data, namely, the video remote inspection system, the ARTG control network machine video unit, and the equipment online monitoring system.

[0046] The core of data interaction is the core data switch, which is a data core processor with data aggregation and convergence. The core data switch is connected to the system core controller and the video data core controller respectively. The system core controller is the control center of the entire system, including data interaction mechanism, data storage mechanism and data isolation protection mechanism. The video data core controller is mainly responsible for the management of the real-time interactive control mechanism of video data; since the video data has a storage function on the NVR hard disk recorder on the stand-alone side, data storage is no longer performed on the video processing core end.

[0047] 3. Network data security isolation is achieved by isolating the interaction unit between the subsystem and the automation system (1) Design of separate physical links In the present invention, different networks are completely separated by physical links. Both the ARTG control network machine video unit and the video remote inspection system have single-machine side data collection, and the data of the video remote inspection system avoids the PLC control interleaving of the ARTG control network machine video unit; and each data uses independent data return links to interact with the core data switch port in the data aggregation.

[0048] (2) No direct interaction with real-time operation data Inspection and operation monitoring are completely separated in time. Since inspection does not require real-time performance, retrieving memory data through the NVR hard disk recorder also effectively avoids the interaction with real-time operation data.

[0049] (3) Using a dedicated data interaction mode In the unavoidable data interaction design, the video playback data extraction of the ARTG control network machine video unit and the data interaction with the core data switch adopts the layout of upstream and downstream independent data interaction isolation switches, and adds data interaction of dual network card servers to achieve the separation of physical links; data interaction is completed through network interaction and data exchange with the isolation server itself. At the same time, Vlan is optimized and planned, and the network of the upstream and downstream independent data interaction isolation switches is separated at the algorithm layer.

[0050] (4) Network deployment has a fully complete VLAN planning In establishing the communication mechanism, we fully considered the security design in the network VLAN settings of each switch and controller, and made rigorous and perfect VLAN planning, which also optimized the network security and protected and controlled the data at the software and port levels. At the same time, the optimized and perfect VLAN settings also made sufficient redundant design planning for subsequent expansion.
