Description

Technical Field

[0001] The invention relates to the field of subway integrated monitoring systems, and in particular to an interface parallel distribution method and system for transforming integrated monitoring systems. Background Art

[0002] At present, in major cities in my country, subways have been developed as transportation infrastructure for a long time. The equipment and systems built and put into operation in the early stage are facing challenges in many aspects due to their long operation time, such as technology updates, increased safety requirements, improved operational efficiency, functional expansion, user experience optimization, and expansion of urban rail transit networks. As an important part of the subway, the integrated monitoring system (ISCS) needs to be combined with the platform operation status and accelerate the upgrading of hardware and software systems to effectively meet the development needs of urban rail transit operations.

[0003] The current subway integrated monitoring system, such as Figure 1 As shown in the figure, each subway line is implemented by a comprehensive monitoring system platform, which includes the center level and station level (station depot / parking lot). The station-level comprehensive monitoring communicates with various professionals through open standard industrial control protocols or Internet protocols. The station-level comprehensive monitoring and the center-level comprehensive monitoring platform communicate internally through the platform's private protocol. The main equipment of the station-level comprehensive monitoring system includes the station server, station FEP, and station workstation. The main equipment of the center-level comprehensive monitoring includes the center real-time server, center history server, center FEP, and center workstation. The professionals connected at the station level mainly include: substation comprehensive automation system PSCADA, environment and equipment monitoring system BAS, fire automatic monitoring system FAS, access control system ACS, platform door system PSD, broadcasting system PA, video monitoring system CCTV, uninterruptible power supply UPS, etc. The professionals connected at the center level mainly include: train automatic monitoring system ATS, passenger information system PIS, broadcasting system PA, video monitoring system CCTV, clock system CLK, automatic ticket vending and checking system AFC, uninterruptible power supply UPS, etc.

[0004] The system with station-level access collects real-time data of various disciplines at the station and sends it to the center and the station at the same time. The system with center-level access collects real-time data of various disciplines at the center and sends it to the center and the station at the same time. The control command is sent from the workstation to the server where the workstation is located, and then sent by the server to the FEP where the interface is located, and then sent by the FEP to the corresponding discipline. The station and the center ensure the uniqueness of the control command issued by the transfer of control rights.

[0005] There are two types of internal data flows between the integrated monitoring system center and the station due to different platform design ideas and implementation methods of different manufacturers. One is that FEP collects various professional data and sends them to the center and station servers at the same time (such as Figure 2 The real-time data flow 1 shown in the figure is that after FEP collects the professional data, it is only sent to the station server (central server), and then the station server (central server) sends it to the central server (station server) (such as Figure 3 The real-time data flow shown in Figure 2). The internal data flow of the integrated monitoring system center and the station is a private protocol and is not open to the outside world. Therefore, the central stations on different platforms are not compatible. In most cases, the old and new platforms before and after the line upgrade are different.

[0006] When the integrated monitoring system of the line is upgraded, temporary equipment will be set up at all stations and centers to carry the new platform. After the debugging of the new platform is completed, it is necessary to switch between the old and new platforms. The switching operation requires that all professionals be connected from the old platform to the new platform carried by the temporary equipment within a construction window. The risks faced at this time are: (1) One operation point needs to switch the profession of the entire line, which is a large workload and time-consuming. In case of emergency, it is necessary to return to the old platform for operation, which will be even more time-consuming and will inevitably affect the operation of the next day. (2) The new platform has only completed function and data verification, and its stability in the field environment has not been verified for a long time. If a problem occurs, it will take a long time to return to the old platform, which will inevitably affect the operation of the next day.

[0007] As one of the key systems to ensure the safe and efficient operation of the subway, the comprehensive monitoring system plays an irreplaceable role and is an indispensable part of the daily operation of the subway. How to complete the transformation and upgrading of the system with as little or no impact on the daily operation of the subway as possible has become a difficult problem currently faced by the industry.

[0028] The system provided by the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0029] Example 1 like Figure 4 As shown, this embodiment provides an interface parallel distribution method for comprehensive monitoring system transformation, which is used to connect new and old platforms with various professions; The new platform includes a new platform server and a new platform FEP that are communicatively connected to each other, and the old platform includes an old platform server and an old platform FEP that are communicatively connected to each other; The old platform FEP is connected to the first address processing device through a first external interface, the new platform FEP is connected to the second address processing device through a second external interface, each professional is connected to the data receiving and distributing device through a third external interface, and the first address processing device and the second address processing device are connected to the data receiving and distributing device through internal interfaces respectively; When upgrading and renovating, and running new and old platforms in parallel: For the collected data stream, the data receiving and distributing device collects real-time data of each profession through the interface IP and interface protocol of the third external interface, and then distributes it to the first address processing device and the second address processing device through the interface IP and interface protocol of the internal interface; after the first address processing device and the second address processing device respectively perform IP address conversion, the received data is sent to the new platform FEP and the old platform FEP respectively according to the interface IP and interface protocol of the first external interface and the second external interface; For controlling data flow, the new platform FEP sends the control command to the second address processing device through the interface IP and interface protocol of the second external interface, the second address processing device sends it to the data receiving and distributing device through the interface IP and interface protocol of the internal interface, and the data receiving and distributing device sends it to each profession according to the interface IP and interface protocol of the third external interface; The old platform FEP sends the control command to the first address processing device through the interface IP and interface protocol of the first external interface, and the first address processing device sends it to the data receiving and distributing device through the interface IP and interface protocol of the internal interface, and the data receiving and distributing device sends it to each profession according to the interface IP and interface protocol of the third external interface.

Figure 5 As shown, when the new and old platforms are running in parallel, if an abnormality occurs in a certain major, unplug the network cable corresponding to the interface IP and interface protocol of the abnormal major in the second address processing device, and connect the actual network cable of the abnormal major to the network interface of the old platform FEP, so as to restore the major to the state before the upgrade and transformation, and ensure the normal operation of the original system.

[0031] In some exemplary embodiments, for controlling the data flow, a single platform control mode in which either the new platform or the old platform performs control, and a dual platform control mode in which the new platform and the old platform perform control alternately may be set; When using dual-platform control, based on the control logic and security considerations of the industrial control protocol, the new and old platforms are not allowed to control the same interface in parallel. The control commands received in sequence in the interface are executed to ensure the uniqueness of the control commands. In a certain interface, when the control process of either the new or old platform is in progress, the control command sent by the other party will be rejected. When the control command of one party in the interface is completed, the new control command received will be executed normally.

[0032] Example 2 This embodiment provides an interface parallel distribution system for comprehensive monitoring system transformation, such as Figure 4 As shown, it includes a parallel distribution system for connecting new and old platforms and interfaces of various disciplines; The new platform includes a new platform server and a new platform FEP that are communicatively connected to each other, and the old platform includes an old platform server and an old platform FEP that are communicatively connected to each other; The interface parallel distribution system comprises a data receiving and distributing device, and a first address processing device and a second address processing device respectively connected to the data receiving and distributing device through internal interfaces; The first address processing device is connected to the old platform FEP through a first external interface, the second address processing device is connected to the new platform FEP through a second external interface, and the data receiving and distributing device is connected to each professional through a third external interface; The new platform FEP is used to send the control command to the second address processing device through the interface IP and interface protocol of the second external interface; The old platform FEP is used to send the control command to the first address processing device through the interface IP and interface protocol of the first external interface; The data receiving and distributing device is used to collect real-time data of each profession through the interface IP and interface protocol of the third external interface, and then distribute it to the first address processing device and the second address processing device through the interface IP and interface protocol of the internal interface; it is used to receive the control command sent by the second address processing device through the interface IP and interface protocol of the internal interface, and send the received control command to each profession according to the interface IP and interface protocol of the third external interface; it is also used to receive the control command sent by the first address processing device through the interface IP and interface protocol of the internal interface, and send the received control command to each profession according to the interface IP and interface protocol of the third external interface; The first address processing device is used to send the received real-time data of each profession to the old platform FEP according to the interface IP and interface protocol of the first external interface after performing IP address conversion; and is used to receive the control command sent by the old platform FEP through the interface IP and interface protocol of the first external interface, and send the received control command to the data receiving and distributing device according to the interface IP and interface protocol of the internal interface; The second address processing device is used to send the received professional real-time data to the new platform FEP according to the interface IP and interface protocol of the second external interface after IP address conversion; it is used to receive the control command sent by the new platform FEP through the interface IP and interface protocol of the second external interface, and send the received control command to the data receiving and distribution device according to the interface IP and interface protocol of the internal interface.

[0033] The system of this embodiment can realize parallel access of each profession to two systems (new and old platforms). If a fault is found during operation, a single profession can quickly restore FEP to the profession for fast direct connection to restore the original communication solution. Figure 5 As shown, when the new and old platforms are running in parallel, if an abnormality occurs in a certain major, unplug the network cable corresponding to the interface IP and interface protocol of the abnormal major in the second address processing device, and connect the actual network cable of the abnormal major to the network interface of the old platform FEP, so as to restore the major to the state before the upgrade and transformation, and ensure the normal operation of the original system.

[0034] In some exemplary embodiments, for controlling data flow, the interface parallel distribution system may be configured with a single platform control mode in which either the new platform or the old platform performs control, and a dual platform control mode in which the new platform and the old platform perform control alternately; When using dual-platform control, based on the control logic and security considerations of the industrial control protocol, the new and old platforms are not allowed to control the same interface in parallel. The control commands received in sequence in the interface are executed to ensure the uniqueness of the control commands. In a certain interface, when the control process of either the new or old platform is in progress, the control command sent by the other party will be rejected. When the control command of one party in the interface is completed, the new control command received will be executed normally.

[0035] When controlling specifically, Figure 6 As shown, the interface parallel distribution system is set up: An operation management module is used to read the parameters of the configuration file when the interface parallel distribution system is started, open a corresponding data area according to the parameters of the configuration file, and start the background service management process and the log message saving process at the same time; the background service management process is used to manage all business processes, and start each professional business process according to the professional configuration of the third external interface; it also provides visual system operation status monitoring and control functions for each process; A professional receiving and distributing module is used to establish network connection channels with the first and second address processing devices and each profession respectively according to the configuration file and maintain them in real time, use the internal protocol to send and receive messages for the connection channels of the first and second address processing devices, and use the interface protocol of the third external interface to parse received messages and organize sent messages for the connection channels of each profession; A professional address processing module is used to establish network connection channels with the data receiving and distributing device and the new and old platforms respectively according to the configuration files and to perform real-time maintenance, and to use the interface protocol of the internal interface to send and receive messages for the connection channel of the data receiving and distributing device, and to use the corresponding interface protocols of the first external interface and the second external interface to parse received messages and organize sent messages for the connection channel of the new and old platforms; The log module is used to save the system operation log in real time and save the real-time communication messages of each interface according to the configuration file for system maintenance; The configuration management module is used to provide a visual interface tool to manage the network IP, network port, protocol type (Modbus protocol, IEC104 protocol, etc.) and parameters within each protocol of the system running saved in the database, and provide a unified data configuration read and write interface for other modules to call.

[0036] Specifically, Figure 7 As shown, the first address processing device is composed of an industrial computer and the system software running on it, and the system software includes the operation management module, log management module, configuration management module of the interface parallel distribution system and various professional address processing modules such as BAS and PSCADA. The second address processing device has the same functional module as the first address processing device, but the connection IP with the data receiving and distributing device is different.

[0037] The data receiving and distributing equipment consists of an industrial computer and the system software running on it. The system software includes the operation management module, log management module, configuration management module of the interface parallel distribution system and various professional data receiving and distributing modules such as BAS and PSCADA. Among them, the BAS data receiving and distributing module connects to the BAS professional equipment for data communication, and then connects to the BAS address processing module for data communication. The same is true for other professional equipment such as PSCADA.

[0038] The receiving and distributing function flow of the present invention is as follows: Figure 8 As shown: (1) The professional receiving and distribution process starts by reading the configuration parameters such as the network IP, port and interface protocol of the major from the database, and checking the legitimacy of the configuration data.

[0039] (2) Create and initialize the professional data buffer and the professional message buffer. Create the address processing device data thread and the professional data thread.

[0040] (3) Professional data processing thread; A) Create a network client and actively connect to the profession; B) A new connection is established and identification is initialized according to the protocol; C) After initialization is completed, send messages according to the configuration to collect data; D) Process the received message according to the protocol and write the collected data into the data buffer.

[0041] (4) Address processing device data thread; A) Create a network monitor and wait for the address processing device to connect; B) A new connection is established, identity recognition fails, and the connection is disconnected and waiting for a new connection; C) Identity recognition is successful and initialization is carried out according to the protocol; D) Waiting for receiving messages after initialization is completed; E) Process the received message and read the data from the data buffer according to the protocol to send a reply message.

[0042] When the integrated monitoring system of the line is upgraded, temporary equipment will be set up at all stations and centers to carry the new platform. After the debugging of the new platform is completed, the old and new platforms need to be switched. Because the functions of the integrated monitoring system require all stations on the entire line to be connected to complete, a switching operation requires that all the professional services at each station be connected from the old platform to the new platform carried by temporary equipment in one construction window. Generally, there are 10 to 30 stations on a line (actually there are more than 60 stations on the line), and each station has about 8 professional services. Generally, the subway operation time is from 6 am to 11 pm. Because various preparations such as track rolling vehicles are required every morning, a construction window is 23:30 to 4:30, a total of 4 hours, so the time is extremely tight and there are greater risks.

[0043] When the interface parallel distribution system of the present invention is used, after the new platform is built, one station and one profession can be connected to the parallel distribution system. After connecting to the parallel distribution system, the old platform connected to this profession is still fully functional, and the new platform is connected to the new profession for testing and verification. One construction window can be connected to either a profession or a station, and is not limited by the construction window time. Users can still use the old platform during this period without being affected, which greatly reduces the upgrade risk.

[0044] In addition, the integrated monitoring system of the line requires the platform software and the actual hardware, network, and interface systems on site to work as a whole to realize actual functions. During the upgrade process, the early debugging only verified the data configuration and the functions of some single stations. Some functions based on the entire line were not fully verified, and the overall stability of the system had not been verified for a long time, which posed a great risk.

[0045] When the interface parallel distribution system of the present invention is used, after connecting to the parallel distribution system at each station and profession, the old and new platforms run at the same time and have both functions and can be used. During this time, the user can verify the functionality and stability of the new platform for a long time, and then dismantle the old platform.

[0046] Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
