Description

Technical Field

[0001] The present invention relates to urban rail transit management, and in particular to a method for synchronizing a line-network fusion platform and a line model based on a physical model. Background Art

[0002] With the gradual improvement of urban rail transit, the complexity of urban rail transit lines has also increased accordingly. The number of urban rail transit sub-equipment such as vehicles, tracks, power grids and stations has also increased significantly. In order to efficiently manage the various sub-equipment in urban rail transit lines, urban rail transit operating companies currently usually adopt a line network center approach for management, that is, integrating multiple lines into a central network platform for unified management.

[0003] However, in urban rail transit construction, the construction cycles of the network center, line center and station are not synchronized, and there are large differences between integrators and equipment manufacturers. As a result, there are great differences in the feature descriptions of urban rail transit sub-equipment between the network center model and the line and station models. The difference in the feature description method means that the control method for the equipment will be different. Different control instructions are required to manage equipment with the same or similar functions. This makes it difficult to use an integrated platform to uniformly manage the entire network system in the same way.

[0004] In order to overcome the differences in the description of urban rail transit sub-equipment between models, which leads to reduced management efficiency, the station equipment, line network synchronization and line network integrated monitoring platform are unified based on the physical model description method. However, the direct use of product physical models in the urban rail transit line network integration platform has problems such as difficulty in describing special equipment functions, conditional relationships, equipment relationships, control relationships, and permissions. Because the line network integration platform not only needs to manage a large number of equipment models, but also the relationships between these devices, control rules, multi-station concurrency and other advanced relationships, the traditional physical model management and synchronization methods cannot meet the needs of the urban rail transit line network integration platform for powerful monitoring functions.

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0019] The present invention provides a line-network fusion platform based on a physical model, which is used for urban rail transit and includes a physical model monitoring and management platform and a line part.

[0020] In specific implementation, urban rail transit sub-equipment refers to various equipment managed and involved in the urban rail system, ranging from trains, tracks and platform doors to transformers, circuit breakers or disconnectors in power grid lines, all of which belong to the urban rail transit sub-equipment in the present invention and can be uniformly controlled and managed based on the line-network fusion platform based on the physical model provided by the present invention.

[0021] In the specific implementation, the line part is connected to various parts and sub-equipment of urban rail transit, wherein the equipment application management department can obtain the operation mode of each sub-equipment that makes an operation request, and the equipment relationship management department can obtain the operation sequence relationship between multiple sub-equipment. The line part transmits the obtained information data to the physical model monitoring and management platform, and the physical model monitoring and management platform reviews the operation requests and operation relationships of the sub-equipment based on the information data, thereby realizing unified and effective management of all sub-equipment in urban rail transit.

[0022] In specific implementation, the Product Thing Model is an important concept in the field of Internet of Things (IoT). It is used to describe the abstract representation of "things" or devices in the physical world. The thing model defines a set of properties, services, and events for each device connected to the IoT platform, so that these devices can be identified, managed, and interacted on the platform. The thing model is a bridge between devices and platforms. Attributes are parameters that describe the current state of the device. They are usually data points that can be read and written, such as the current temperature value of a temperature sensor. Attributes can be divided into read-only attributes and read-write attributes; services are a set of functions or operations that devices can perform in response to requests from the platform or other devices, such as turning on and off the air conditioner. Services can contain input parameters and output results to support more complex interactions; events are messages triggered by devices in specific situations to notify the platform or other devices that something important has happened. For example, a smoke alarm triggers an alarm event when smoke is detected.

[0023] In an embodiment of the present invention, the professional application unit is used to provide a corresponding communication interface according to the transmission protocol used by the sub-device; for sub-devices of the same type divided by the device type unit, the same communication interface is provided, and the address of the communication interface is provided to the device model unit; if the sub-device is a priority device or the transmitted data is priority data, a corresponding priority communication port is provided.

[0024] In the specific implementation, professional application management is the basis for all sub-device data reporting and command transmission. Professional application management synchronization includes query, deletion, and control of application environment configuration model management. The synchronization interface can be used to configure the line network and line or station data communication using communication protocols, support lines with multiple interface machines or multiple station access requirements, and support IEC104, Modbus, MQTT, HTTP / HTTPS and other general protocols in line operation. The main contents of the synchronization request format are shown in Tables 1 to 3 (taking new construction as an example):

[0030] Table 3 (return body format):

[0031]

[0032] In an embodiment of the present invention, the device type unit is used to classify sub-devices according to their functions or uses, and synchronize sub-device sets of the same type to the product physical model unit and the physical model monitoring and management platform. The physical model monitoring and management platform performs topological coloring, power flow analysis or energy management analysis on sub-device sets of the same type.

[0033] In specific implementation, device type management is about the detailed management of device classification. For example, for the same type of device descriptions such as circuit breakers, knife switches, transformers, etc., the line network platform can perform some advanced functional data analysis based on the device type. The classification of sub-device types is the basis for the description of product physical models, because sub-devices that usually have the same or similar functions or uses can be described in the same physical model description method. For example, the dynamic properties of the above-mentioned circuit breakers, knife switches, and transformers can read parameters including electrical parameters such as voltage. On the other hand, by classifying sub-devices by type, it is also possible to overcome the disadvantage that when managing the same type of sub-devices, it is difficult to uniformly manage the same type of sub-devices through specific parameters or other characteristics when the specific parameters or other characteristics vary greatly due to the different integrators and equipment manufacturers of the sub-devices.

[0034] The synchronization request format is shown in Table 4 and Table 5 (taking new creation as an example):

[0035] Table 4:

[0040] In an embodiment of the present invention, the product physical model unit uses the same physical model description for a set of sub-devices of the same type, and synchronizes the physical model description of the sub-device to the device model unit and the physical model monitoring and management platform; in the physical model description, attributes include static attributes and dynamic attributes, static attributes represent inherent parameters of the sub-device, and dynamic attributes represent readable and writable variable parameters of the sub-device; services include ordinary services and message services, ordinary services represent inherent functions of the sub-device, and message services represent communication functions of the sub-device; events represent fault triggering and recovery information of the sub-device; files represent work record information of the sub-device.

[0041] In the specific implementation, product object model management is about the management of specific attributes, events, services, and files of equipment. It describes the specific monitoring content of equipment of the same type or the same manufacturer in the line. The attributes are divided into static attributes and dynamic attributes. Static attributes are some inherent attributes of the equipment that will not change. Dynamic attributes are some changes, such as voltage, current, switch position, etc. Events refer to some subsystem equipment that describes fault event information. Services are mainly some control functions and parameter setting functions. Service types are divided into message types and ordinary types. Ordinary types include switch control, and message types include schedule control, parameter setting, broadcast control, etc. File management is based on the characteristics of urban rail transit monitoring. It is necessary to read equipment and subsystem related files for analysis and display, such as fault recording files, timetable files, etc. The traditional object model is distinguished by more detailed object model content to better meet the needs of rail transit operation scenarios. The new interface synchronization content request format of the product object model is shown in Table 6 and Table 7:

[0048] In the specific implementation, the device model management is the instantiation content of all devices according to the product object model, which describes the specific operating status of a specific single device. The specific device model synchronization request format is as shown in Table 8 to Table 11:

[0058] In the embodiment of the present invention, the device relationship unit is used to synchronize the association relationship and current communication connection relationship between sub-devices to the physical model monitoring and management platform; the association relationship of the sub-devices is determined in combination with the dynamic attributes described by the physical model.

[0059] In specific implementation, device relationship management is the description of the connection relationship between device nodes and the interrelated action relationship of devices added according to the operation characteristics of the urban rail transit integration platform. The main content description of the device node connection relationship (referenced in the device model unit) is shown in Table 12 to Table 14:

[0067] In the embodiment of the present invention, the conditional relationship unit is used to add the operating conditions of the sub-device to the common services in the description of the sub-device object model.

[0068] In the specific implementation, conditional relationship management is to add descriptions of conditional relationships based on the operational characteristics of the urban rail transit integration platform. The relevant controls need to meet the conditions before the relevant execution control content can be carried out (referenced in the equipment model unit and the sequential relationship unit). The synchronization content of the conditions is shown in Tables 15 to 18:

[0077] In the embodiment of the present invention, the sequence relationship unit is used to determine whether multiple sub-devices requesting to run are concurrently controlled or sequentially controlled, and to add the running sequence relationship of the sub-devices to the common services in the sub-device object model description.

[0078] In specific implementation, sequence relationship management is to add descriptions of sequence relationships based on the operational characteristics of the urban rail transit integration platform. The sequence relationship is to improve the control efficiency of on-site equipment and optimize the control process. It executes batch control content according to predefined content and supports concurrent control of multiple station equipment at the same time (step), thereby improving the work and operational efficiency of dispatchers. The sequence relationship synchronization content is shown in Tables 19 to 21:

[0087] In the specific implementation, the authority management is to add the authority management function according to the operation characteristics of the urban rail transit integration platform. The authority management is the authority description of sub-specialties and equipment in different authority positions (line network, line, station, sub-specialty, subsystem module, equipment). It is the basis for the line network integration platform to clarify the equipment control right and security control. The synchronization content of the authority management is shown in Table 22 and Table 23:

[0093] The present invention also provides a line model synchronization method based on a physical model, and the line network fusion platform based on the physical model provided by the present invention is applied, including: a physical model monitoring and management platform receives a sub-device set of the same type synchronized by a device type unit and a product physical model unit, a physical model description, and an actual operation process of a single sub-device, wherein the actual operation process of the sub-device includes the operation conditions and operation sequence relationship of the sub-device; the physical model monitoring and management platform receives the association relationship and the current communication connection relationship between the sub-devices, the operation conditions of the sub-devices, the operation sequence relationship and the authority of the sub-devices synchronized by the device relationship management department; the physical model monitoring and management platform determines whether the sub-device set conforms to the same type, and if so, determines whether the physical model description is consistent with the actual application, and if so, reviews the actual operation process of the single sub-device, and after the review is passed, reviews the sub-device relationship data synchronized by the device relationship management department; the physical model monitoring and management platform determines whether the corresponding sub-device has a fault according to whether the association relationship between the sub-devices and the current communication connection relationship are consistent, and if there is no fault, reviews whether the operation conditions of the sub-device are met, and if so, reviews whether the operation sequence relationship of the sub-device conforms to the authority level of the corresponding sub-device, and if so, approves the operation request of the sub-device.

[0094] In a specific implementation, when the physical model monitoring management platform reviews the information data synchronized between the device relationship management department and the device relationship management department, if there is any failure in the review, the review will be stopped and manual operation and maintenance correction can be performed.

[0095] In a specific implementation, a sub-device with an associated relationship refers to a specific sub-device and a sub-device that should have an operating communication relationship with the specific sub-device. If the sub-device that a specific sub-device is currently communicating with is inconsistent with the sub-device that should have an operating communication relationship, this indicates that the specific sub-device may have a fault, or that a sub-device that should have been communicating with the specific sub-device but was not actually communicating with the specific sub-device has a fault.

[0096] In the specific implementation, reviewing whether the operation sequence of sub-devices complies with the permission level of the corresponding sub-devices refers to whether the operation sequence of the sub-devices is consistent with the permissions of the sub-devices. For example, high-priority sub-devices should be run first, and low-priority sub-devices should be run later.
