[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0033] It's important to understand that car dumpers, as key equipment specifically designed to efficiently unload bulk materials (such as coal, ore, and other bulk cargo) from railway freight cars, play an indispensable role in modern logistics, energy, and mining. These locations, such as busy ports, large power plants, and deep mines, rely heavily on car dumpers to rapidly move and process cargo. Traditionally, car dumper control systems have mostly adopted a centralized control architecture, relying on a reliable and flexible programmable logic controller (PLC) to execute complex control logic and operating instructions. Due to its powerful data processing capabilities and stability, PLCs have long been the mainstream choice for car dumper control systems.

[0034] However, as the functionality of dumper systems has grown increasingly complex, the traditional centralized control model has begun to expose more and more limitations. Primarily, the issue of system scalability is the primary concern. Faced with growing processing demands and constantly evolving equipment configurations, centralized control systems often struggle to smoothly expand functionality without significant structural modifications. Furthermore, maintenance of centralized control systems has become increasingly burdensome and complex. System failures often require lengthy diagnostic and repair cycles, posing a direct challenge to production efficiency and operating costs.

[0035] More crucially, the operating environment of a modern car tipper often involves close interaction with a variety of peripheral equipment, including but not limited to a re-adjuster (for precise positioning and adjustment of cars), a car transfer platform (for rapid transfer of cars between different tracks), and an air conditioner (to ensure a suitable operating environment and stable equipment operation). The coordinated operation of these devices requires highly precise time synchronization and complex logical control. However, traditional centralized control systems are often designed to lack support for parallel processing and efficient collaboration of multiple devices, thus limiting the efficiency and flexibility of the entire operation process.

[0036] Based on this, the present application improves the traditional distributed control system and control method for dumpers.

[0037] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the framework structure of the distributed control system provided in this embodiment. Figure 2 A schematic diagram of another framework structure of the distributed control system provided in this embodiment; Figure 2 The substation system corresponds to the sub-control station 200, and the central control computer corresponds to the main control station 100. This embodiment provides a distributed control system for a tipping machine 300, which has multiple extended function modules 310. The distributed control system includes a main control station 100 and multiple sub-control stations 200: the multiple sub-control stations 200 are used to be connected to the multiple extended function modules 310 in a one-to-one correspondence, and the multiple sub-control stations 200 are connected to the main control station 100; the sub-control stations 200 are used to collect information from the corresponding extended function modules 310 and upload the collected data to the main control station 100; and / or, the sub-control stations 200 are used to control the extended function modules 310 based on the control signals of the main control station 100; wherein the multiple extended function modules 310 include at least one of a readjustment motor module, a tipping motor module, a transfer platform motor module, an air conditioning motor module, and a rail clamp module.

[0038] It should be explained that in order to adapt to different operational requirements and environmental conditions, the car tipper 300 system is equipped with a variety of functional modules, such as a readjustment motor module (used to adjust the position of a fully loaded car), a tipping motor module (which drives the car tipper 300 to flip the car to unload cargo), a car transfer platform motor module (which moves the car to a designated position), an air conditioning motor module (which adjusts the position of an empty car), and a track clamp module (which ensures the stability of the car). These modules are key components for the efficient and safe operation of the car tipper 300. The readjustment motor module is used to pull the car when it is loaded with material; the tipping motor module is used to dump the material when flipping the car, and to reset the flipped car; the car transfer platform motor is used to move the car loaded with material to the tipping position, and to move the car to the track after it has been reset; the air conditioning motor module is used to pull the empty car on the track, and the track clamp module is used to fix the car tipper 300 on the track.

[0039] It can be understood that the main control station 100, as the core of the entire distributed control system, is responsible for receiving data from each sub-control station 200, performing high-level data processing, logical analysis, and decision-making, and issuing control instructions to the corresponding sub-control station 200. The number of sub-control stations 200 matches the number of extended functional modules 310 in the dumper 300. Each sub-control station 200 is responsible for controlling and collecting data for one or more specific functional modules. They interact directly with the controlled objects (i.e., extended functional modules 310). Sub-control stations 200 periodically or on demand collect data such as the operating status and parameters of their functional modules and upload this information to the main control station 100. Based on the received data and combined with pre-set control logic and algorithms, the main control station 100 generates control instructions and transmits them to the corresponding sub-control station 200 via the communication network. Upon receiving the instructions from the main control station 100, the sub-control station 200 immediately executes control operations for the functional modules, such as starting, stopping, and adjusting parameters.

[0040] The current tipping machines 300 are mostly controlled by PLC systems, which makes it difficult to achieve collaborative work of multiple devices. However, in this application, multiple sub-control stations 200 are set up to monitor and control different extended functional modules 310, forming a distributed control structure, which is conducive to the collaborative work of multiple devices and the comprehensive perception of multiple devices. The distributed control system in this application allows the addition or removal of functional modules and the adjustment of control strategies according to actual needs, thereby improving the scalability and adaptability of the system. And through decentralized control, the impact of single-point failures on the entire system is reduced, and the stability and reliability of the system are improved. And because the system structure is clear and modular design, fault diagnosis and maintenance become easier and more efficient.

[0041] Specifically, in this application, by constructing an intelligent integrated management platform for distributed control, it is possible to fully and effectively process and utilize various information data, so that the management of the main control station 100 and the surrounding supporting sub-control stations 200 can be highly centralized and convenient and fast. System integration can give full play to the advantages of products and technologies of different manufacturers, and through the collection, processing, storage and analysis and organization of information, it becomes a data resource with high added value, thereby making equipment operation and maintenance and integrated business management more efficient and intelligent. In addition, the integrated design fully reflects the characteristics of the intelligent complex, realizes the sharing and management of information resources between the various intelligent subsystems in the dumper 300 complex, and realizes the interoperability, fast response and linkage control between related subsystems, so as to achieve the goals of automatic monitoring and remote management.

[0042] More specifically, the overall structure of the distributed control system in this application adopts a standard structured and modular system, which can enable equipment products from different manufacturers to be easily and quickly integrated on one platform, with quick construction and easy use; it has sufficient redundancy in software and hardware configuration, so that the system can be easily expanded in the future, meeting the requirements of versatility and replaceability.

[0043] More specifically, the distributed control system in this application can provide decentralized control, as well as centralized management and monitoring of each sub-control station 200. The integrated system should be an open system, enabling interoperability of interfaces and protocols between different sub-systems and products.

[0044] In some embodiments, different devices are interconnected, and different sub-control stations 200 are interconnected, using a network-based standardized protocol and time synchronization management to ensure that the time of each sub-control station 200 is consistent.

[0045] In some embodiments, the data collected by the sub-control station 200 from the motor module of the dumper 300 include at least one of three-phase voltage, three-phase current, active power, reactive power, power factor, frequency, forward active power, forward reactive power, reverse active power, reverse reactive power, number of reversals, operating status, oil pressure data, in-position data, and reversal angle.

[0046] In some embodiments, the data collected by the sub-control station 200 of the readjustment motor module includes at least one of three-phase voltage, three-phase current, active power, reactive power, power factor, frequency, forward active power, forward reactive power, reverse active power, reverse reactive power, and operating status.

[0047] In some embodiments, the data collected by the sub-control station 200 from the transfer platform motor module includes at least one of three-phase voltage, three-phase current, active power, reactive power, power factor, frequency, forward active power, forward reactive power, reverse active power, reverse reactive power, and operating status.

[0048] In some embodiments, the data collected by the sub-control station 200 from the air-conditioning motor module includes at least one of three-phase voltage, three-phase current, active power, reactive power, power factor, frequency, forward active power, forward reactive power, reverse active power, reverse reactive power, and operating status.

[0049] In some embodiments, the data collected by the sub-control station 200 from the rail clamp module includes at least one of three-phase voltage, three-phase current, active power, reactive power, power factor, frequency, oil pressure data, in-position data, and operating status.

[0050] In some embodiments of this application, please continue to refer to Figure 2In this embodiment, the main control station 100 and the plurality of sub-control stations 200 are connected via optical fibers.

[0051] In some embodiments of this application, please continue to refer to Figure 2 The sub-control station 200 of this embodiment is used to collect output data of the hydraulic unit of the extended function module 310 and to output data to the hydraulic unit of the extended function module 310 .

[0052] In some embodiments, please refer to Figure 2 , the sub-control station 200 is further used to obtain the position signal of the motor of the extended function module 310 to perform position protection on the motor of the extended function module 310;

[0053] In some embodiments, please refer to Figure 2 The sub-control station 200 is further configured to output analog signals to the extended function module 310 to monitor or adjust the extended function module 310 .

[0054] In some embodiments of this application, please continue to refer to Figure 2 The extended function module 310 of this embodiment also includes at least one of a hook-removing robot unit, a pre-flip empty vehicle detection device unit, a residual material visual perception and cleaning unit, and a dust removal unit.

[0055] As you can see, the hook removal robot unit is used to mechanically remove the connecting hooks between carriages, and the empty vehicle detection device unit monitors whether the vehicle is empty to ensure efficient unloading. The residual material visual perception and cleaning unit detects and removes residual material in the carriage. The dust removal unit is used to reduce dust generated during unloading and improve the working environment.

[0056] In some embodiments, the data collected by the sub-control station 200 from the dust removal unit includes at least one of three-phase voltage, three-phase current, active power, reactive power, power factor, frequency, water volume, water level, flow, water pressure, dust concentration, and operating status.

[0057] In some embodiments, the data of the unhooking robot unit of the sub-control station 200 includes at least one of three-phase voltage, three-phase current, active power, reactive power, power factor, frequency, travel data, number of unhooking times, operating status, and fault alarm.

[0058] In some embodiments of this application, please continue to refer to Figure 2 , Figure 2 The main control cabinet and the extended control cabinet are placed in different locations (the first and second floors of the electrical room); the main control station 100 of this embodiment includes a main control cabinet and multiple extended control cabinets, the main control cabinet and the multiple extended control cabinets are connected by optical fibers, and the main control cabinet and the multiple extended control cabinets jointly collect and control multiple extended function modules 310.

[0059] It is understandable that in a highly complex system, the main control cabinet has limited space and cannot support more DI, DO signal processing and electrical wiring resources. It is necessary to expand the control cabinet and sub-control station 200 to support it. Relying on the powerful computing power of the system's central processing unit, the number of control sub-stations can be flexibly expanded as needed without affecting the performance of the main station.

[0060] In some embodiments of the present application, the main control station 100 also includes a first data display unit, which is used to display status information of the tipping machine 300; the distributed control system also includes a monitoring module, which includes a server 400 and a second data display unit that are communicatively connected to each other, and the server 400 is communicatively connected to the main control cabinet, and the second data display unit is used to display information of the tipping machine 300.

[0061] It is understandable that the information of the dumper 300 can be observed on-site through the second data display unit, and the information of the dumper 300 can also be observed remotely through the first data display unit.

[0062] In some embodiments, the server 400 may be connected to multiple main control stations 100 to monitor and control information of multiple dumpers 300 .

[0063] In some embodiments, the data display unit (first data display unit / second data display unit) of the embodiment of the present application displays the important data of each sub-control station 200 through a central data visualization module, and cooperates with the electronic map to realize the dynamic and static display of important sub-control station 200 data in the leadership cockpit interface, dynamically manage the main system data, and present it in the form of pie charts, bar charts, curve charts, etc., so as to intuitively perform data statistics, organization and analysis.

[0064] In some embodiments of the present application, the distributed control system also includes an alarm unit, which is used to output an alarm signal when it detects abnormal information of the tipping machine 300 to prompt the user to take action; the alarm unit is also used to convert the alarm signals in processing and / or after processing into historical alarm records.

[0065] It is understood that the alarm unit mainly includes two functions: real-time alarm and historical alarm. When an alarm occurs, the on-duty personnel perform the corresponding operation according to the system prompts. After the corresponding operation is completed, the alarm information in progress and completed is converted into historical alarm records.

[0066] In some embodiments of the present application, the alarm signal prompts the user in the form of an automatic pop-up alarm interface and / or sound and light prompts; specifically, when an alarm occurs, a real-time alarm interface will automatically pop up and prompt the management personnel in the form of sound and light.

[0067] The alarm interface includes at least one of the alarm time, the alarming sub-control station 200, the alarming device, the location of the alarming device, the alarm content and the alarm level.

[0068] It is understandable that the detailed data of the real-time alarm can be viewed through the real-time alarm interface. And you can also click to jump to the floor interface where the alarm point is located.

[0069] See also Figure 3 , Figure 3 The diagram shows a schematic diagram of the alarm interface provided by this embodiment. Historical alarms are displayed in a list format, with alarm attributes including at least one of the following: alarm status, alarm time, recovery time, processing time, subsystem, device, signal, alarm content, and alarm level. Queries can be performed based on "alarm time, alarm status, subsystem, device, and signal," and query results can be exported. The entire processing process, including alarm content, processing details, and handling personnel, can be viewed. Historical alarms can be analyzed using pie charts based on the number of alarms generated by each subsystem, and using line charts based on the number of alarms generated by date.

[0070] The alarm levels in this embodiment include prompt, general, important, and urgent in order of urgency, and alarm signals of different levels are displayed in different colors.

[0071] Specifically, this system adopts a real-time centralized alarm management method, which can centrally display and process various alarms in each system. The alarm level is divided into four levels by default: prompt, general, important, and emergency, represented by blue, purple, orange and red respectively. Prompt: The operating status of important equipment in important areas. General: The failure of some ordinary equipment will not affect the overall performance of the system operation, and will not have a significant impact on the normal operation of production activities. Important: The failure of some important equipment will affect the performance of the system operation and have an adverse effect on the normal operation of production activities. Emergency: A serious alarm occurs in the system or equipment, which has a serious impact on the operation of the system and the operation of the entire production activity. When an alarm occurs in the system, the real-time alarm interface will pop up automatically, the alarm light will flash in the upper right corner of the system page, and there will be a sound reminder.

[0072] More specifically, when a system alarm occurs, it must be able to notify management personnel of the alarm content through various means, such as sound and light, and display the alarm details. The system will not stop alarming and return to normal operation until the alarm fault is resolved and the management personnel manually deactivate the system alarm and confirm that the fault has been resolved.

[0073] In some embodiments, users can query all alarm and fault information generated by the system according to the conditions of "alarm time, alarm status, subsystem, equipment, signal" and can export historical alarm information in Excel format.

[0074] In some embodiments of the present application, the distributed control system includes a login system, and the login users of the login system include general users, technical users, and management users. Different login users have different permissions to view and control the distributed control system.

[0075] It is understandable that the system can set each user's browsing, control, and editing permissions for each subsystem device. The system default users are divided into three categories: general users, technical users, and management users.

[0076] "General Users" refers to ordinary operators who perform routine maintenance and operation of the system integration platform. They require no specialized knowledge and can use the system integration platform after simple training. These users are limited to manually switching operating modes and viewing key operating parameters of each subsystem within the system integration platform. They can access pop-up alarms and, within the corresponding pop-up interface, manually manipulate the operating status of certain devices for emergency response.

[0077] "Administrative User": This user can view the current operating mode of each subsystem; modify and edit the operating mode; view alarm information; browse important operating parameters of each electromechanical system; and view energy consumption, attendance, and shift scheduling reports. Administrative users can edit access permissions.

[0078] "Technical User": refers to professional technical engineers. Users can view detailed operating parameters of electromechanical equipment; switch between manual and automatic modes; and, in manual mode, manually change the start and stop states of electromechanical equipment and modify set values; and modify and edit operating modes. Professional technicians typically use this system only for system maintenance, optimization, or updates.

[0079] The system presets the default permissions for three types of users, forming the default user class. When editing the permissions of each user, you can modify the specific management permissions based on the selected default user type.

[0080] In some embodiments, the distributed control system also includes a field monitoring unit. This unit is designed to trigger an intrusion alarm signal when a person, animal, or vehicle enters an unauthorized area. A real-time alarm record will appear in the Alarm Management - Real-Time Alarm window, and the associated camera's live feed will automatically pop up. The intrusion alarm system provides an alarm signal, and the video device provides the ability to access real-time video feeds.

[0081] Furthermore, in order to better implement the distributed control system in any of the above embodiments, based on the above distributed control system, the present application also provides a distributed control method for the tipping machine 300, which is applied to the above distributed control system.
