Description

Technical Field

[0001] The present invention relates to the field of rail transit, and in particular to a virtualized integrated control system and method for a rail transit integrated backup disk. Background Art

[0002] The traditional integrated backup disk (IBP disk) is composed of an IBP mosaic panel and a PLC (programmable logic controller). The PLC is only responsible for the acquisition and drive of the BAS profession. Other professions such as signals, access control, gates, and platform doors are directly connected to the IBP disk through hard lines. In particular, the signal part needs to do complex interlocking logic with the interlocking. With the development of rail transit, rail transit signal technology has made breakthrough progress. Large system integration connects signals with integrated monitoring and other professions well, overcoming the problems of complex interfaces and low communication. System integration has become an inevitable trend in the development of future urban rail transit with its high degree of automation, high safety level, and low operating cost.

[0003] The traditional integrated backup simulation system has low scalability, high equipment cost, and no integrated linkage function between the various systems. Judging from the subway accident cases that have occurred in China in recent years, many accidents are caused by the lack of cooperation and coordination between the various systems, and the system is too complex to troubleshoot problems.

[0004] Nowadays, the signal system is shifting towards a fully automatic unmanned integrated system, and the requirements for the safety and stability of the signal system are becoming higher and higher. This places high demands on the safety and stability of signals and other professional products, and also increases the requirements for the integrated backup disk system. The safety and stability of the product are inseparable from the correct output of the test and verification phase. At present, there is no complete virtualized integrated control system for rail transit integrated backup disks. In view of this, how to develop a complete virtualized integrated control system for rail transit integrated backup disks is a problem that needs to be solved at present. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a virtualized integrated control system and method for a rail transit integrated backup disk.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A virtualized integrated control system for a rail transit integrated backup disk, comprising a programmable controller, and the virtualized integrated control system further comprises:

[0008] The integrated backup disk drive module is used to communicate with the programmable controller, the interlocking acquisition drive module and the integrated monitoring system respectively;

[0009] Comprehensive monitoring system, used for real-time centralized monitoring and coordination of mechatronic equipment and subsystems of rail transit;

[0010] Integrated monitoring subsystem simulator, used to realize the communication between the integrated monitoring system and the integrated backup disk drive module;

[0011] Interlocking acquisition driver module, used to collect and set the code position of the interlocking board;

[0012] The simulation platform interface middleware is used to realize the communication between the interlocking acquisition driver module and the integrated backup disk driver module;

[0013] Integrated backup panel interface for displaying rail transit status and generating control signals;

[0014] The programmable controller is respectively connected to the integrated backup disk drive module and the integrated backup disk interface. The integrated backup disk drive module is connected to the interlocking acquisition drive module through the simulation platform interface middleware on the one hand, and is connected to the integrated monitoring system through the integrated monitoring subsystem simulation simulator on the other hand. The programmable controller is also connected to the signal device to integrate the subsystems monitored by the integrated monitoring system, the devices controlled by the interlocking board and the signal device, and realize the linkage of various parts through the integrated backup disk drive module.

[0015] Furthermore, the signal device includes at least one of an emergency stop button, an area blocking button, a platform door and a gate.

[0016] Furthermore, the integrated monitoring subsystem simulation simulator is also used to simulate the subsystems monitored by the integrated monitoring system in rail transit, and the subsystems include signal systems, power automation systems, power monitoring systems, automatic fire alarm systems, access control systems, broadcasting systems, passenger information systems, rail transit video monitoring systems, platform door systems, radio systems, automated warehouse systems, and at least one of the front-end processor simulations of the rail transit integrated monitoring system, thereby enhancing the function of the integrated monitoring subsystem simulation simulator.

[0017] Furthermore, the subsystem simulated by the comprehensive monitoring subsystem simulation simulator is consistent with the actual interface mode, communication protocol, logical association and physical characteristics of the corresponding subsystem, and can realize scenario simulation of multiple simulated subsystems according to scenario requirements, and generate data changes and data association relationships that conform to actual operating conditions. The simulated subsystem is also consistent with the data point table and data content of the communication data packet of the comprehensive monitoring system, and can realize dynamic loading of each simulated subsystem.

[0018] Furthermore, the integrated monitoring subsystem simulation simulator is also used to perform simulation operations on the simulated subsystem, and the simulation operations include at least one of data changes, batch data changes, and coordinated data changes of simulation programs of multiple subsystems.

[0019] Furthermore, the control signal generated by the integrated backup disk interface includes at least one of a fire signal, an escalator signal, a station environmental control signal and a tunnel ventilation signal.

[0020] Furthermore, the integrated backup disk drive module realizes communication with the programmable controller by acquiring and driving the input / output points of the programmable controller.

[0021] Furthermore, the integrated monitoring system performs real-time centralized monitoring of rail transit electromechanical equipment, specifically, real-time centralized monitoring and control of power equipment, fire alarm information and its equipment, station environmental control equipment, section environmental control equipment, environmental parameters, platform door equipment, flood prevention door equipment, escalator equipment, lighting equipment, access control equipment, automatic ticket vending and checking equipment, broadcasting and closed-circuit television equipment, and broadcast information and clock information of the passenger information display system;

[0022] The coordination and linkage specifically refers to the coordinated interaction between rail transit subsystems during non-operating conditions at night, normal operating conditions during the day, emergency situations, and important equipment failure situations.

[0023] This is a common function of the integrated monitoring system in the prior art.

[0024] An application of a virtualized integrated control system of the rail transit integrated backup disk, the application is divided into a collection process and a driving process running in parallel.

[0025] Furthermore, the acquisition process is specifically as follows: if the signal device or the integrated backup disk interface generates a message, it is transmitted to the integrated backup disk drive module through the programmable controller, and the integrated backup disk drive module determines whether the message is a switch quantity change. If the message is a switch quantity change, it further determines whether the message is a signal message. If it is a signal message, it is transmitted to the interlocking acquisition drive module, otherwise it is transmitted to the integrated monitoring system; the signal message is a message generated by the signal device;

[0026] The driving process is specifically as follows: if the interlocking acquisition driving module or the integrated monitoring system generates a driving message, it is transmitted to the programmable controller through the integrated backup disk driving module, and the corresponding signal device is driven by the programmable controller.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] (1) High integration: The traditional integrated backup disk control system simply simulates each system and does not integrate multiple disciplines together. The virtualized integrated control system of the present invention integrates the integrated monitoring system and the interlocking acquisition drive module through the integrated backup disk drive module, and the programmable controller is also connected to the signal equipment, thereby integrating the rail transit electromechanical equipment and subsystems monitored by the integrated monitoring system, the equipment controlled by the interlocking acquisition drive module through the interlocking board, and the signal equipment connected to the programmable controller, thereby overcoming the problems of difficult and complex interfaces between systems and frequent problems in the past.

[0029] (2) Save cost and time: Most traditional integrated backup disk system data tests are completed on the main line, which greatly reduces the problem discovery rate and increases potential accident hazards. If the test center purchases additional equipment that is the same as the main line to meet the test, this greatly increases the cost and time, and the equipment reusability is not high. The virtualized integrated control system of the present invention adopts virtualization technology: through the interlocking acquisition drive module, the code position of the interlocking board is collected and set, and through the integrated monitoring subsystem simulation simulator, the integrated monitoring system and the integrated backup disk drive module are communicated, and through the integrated backup disk drive module, the programmable controller, the interlocking acquisition drive module and the integrated monitoring system are communicated respectively, which greatly saves cost, time and equipment space occupancy.

[0030] (3) Powerful functions and strong scalability: The virtualized integrated control system of the present invention integrates the comprehensive monitoring system with the signal equipment, which is extremely convenient for station data testing. It can configure different test environments according to different projects.

[0031] (4) Universality: The current integrated backup disk systems are all for train control systems of specific manufacturers and models and are not universal. When testing different systems, it is usually necessary to replace the equipment and require a lot of development work, which affects the efficiency of the testing work. The virtualized integrated control system of the present invention can make small changes to the interlocking acquisition driver module, the integrated monitoring system, the integrated monitoring subsystem simulation simulator or the simulation platform interface middleware according to the specific requirements of different projects to meet their testing.

[0032] (5) The virtualized integrated control system of the present invention has been used for in-factory verification tests of actual metro lines such as Shanghai Metro Line 10 and Chengdu Metro Line 9, ensuring the release quality of the above-mentioned metro line signal systems, significantly improving test efficiency, and effectively reducing test equipment costs. The virtualized integrated control system of the rail transit comprehensive backup disk is the development direction of the future rail transit signal system test and verification platform.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment is a virtualized integrated control system for a rail transit integrated backup disk, including an interlocking acquisition driver module (CIAdapter), an integrated monitoring system (ISCS), an integrated backup disk driver module (IBPDriver), a simulation platform interface middleware (FEPSever), an integrated monitoring subsystem simulator (ISCSubSim), an integrated backup disk interface (IBP_HMI) and a programmable controller (PLC).

[0040] The programmable controller is respectively connected to the programmable controller and the integrated backup disk interface, and the programmable controller is connected to the integrated backup disk drive module. The integrated backup disk drive module is connected to the interlocking acquisition drive module via the simulation platform interface middleware on the one hand, and is connected to the integrated monitoring system via the integrated monitoring subsystem simulation simulator on the other hand. The programmable controller is also connected to a signal device, which in this embodiment includes a platform door, an emergency stop button (ESP), an area blocking button (SPKS) and a gate. The platform door referred to in this embodiment is a platform door or a shield door.

[0041] The following is a detailed description of each of the above components:

[0042] 1. Comprehensive backup disk drive module

[0043] The integrated backup disk drive module collects and drives the programmable controller I / O points, and indirectly completes the collection and drive control of the integrated backup disk interface. The integrated backup disk drive module also communicates with the interlocking collection drive module through the simulation platform interface middleware, and at the same time communicates with the integrated monitoring system through the integrated monitoring subsystem simulation simulator.

[0044] 2. Comprehensive monitoring subsystem simulation simulator

[0045] The integrated monitoring subsystem simulator collects the IO, AO, DO and AO code bits of the integrated monitoring system to simulate the various subsystems monitored by the integrated monitoring system (hereinafter referred to as the simulated subsystems). In addition to the signal system, the simulated subsystems also include EMCS (environmental monitoring system), PSCADA (power monitoring system), FAS (automatic fire alarm system), BAS (equipment monitoring system), ACS (access control system), PA (broadcasting system), PIS (passenger information system), CCTV (railway video monitoring system), PSD (platform door system), RADIO (radio system), RS (automatic warehouse system) and other professional and ISCS (integrated monitoring system) FEP ( Front-end processor) simulation, in terms of functions, has the same interface mode as the simulated subsystem, the same communication protocol as the simulated subsystem, the data point table of the communication data packet is consistent with the configuration of the comprehensive monitoring system, the data content is also consistent, and the comprehensive monitoring simulated subsystem can be dynamically loaded; the logical association and physical characteristics are consistent with the simulated subsystem, and according to the scenario requirements, the scenario simulation of multiple simulated subsystems is realized, and the data changes and data association relationships that conform to the actual operating conditions are generated. The simulation programs of multiple simulated subsystems can be simulated through a centralized control interface, and the operations include: data changes, batch data changes, coordination of simulation programs of multiple simulated subsystems (including: simultaneous changes, related changes, etc.) data changes.

[0046] 3. Comprehensive backup disk interface

[0047] The integrated backup panel interface is combined with the touch screen for human-computer interaction, displaying rail transit status, generating control signals, and realizing all the functions of the integrated backup panel. The interface includes signals, platform doors, fire protection, escalators, gates, access control, station environmental control, and tunnel ventilation. The signal displays the status of the emergency stop button and the area blockade button. Figure 2 As shown, the integrated backup disk interface in this embodiment includes a workstation and three touch screens. The workstation is respectively connected to the programmable controller and the three touch screens for communication. The touch screen displays the status of signals, fire protection, escalators, access control, station environmental control (environmental control) and tunnel ventilation (tunnel), and can be set by touch.

[0048] 4. Interlocking acquisition drive module

[0049] The interlocking acquisition driver module is mainly used to assist the simulated trackside equipment in setting and reading the interlocking code position, send control commands through the programmable controller, drive and collect the code position of the interlocking I / O board. It has the functions of receiving VIIB (interlocking input code position) setting messages sent by the simulated trackside equipment, sending VOOB (interlocking output code position) status messages to the simulated trackside equipment, sending read input and set output commands to the programmable controller control, and receiving and sending communication messages through Ethernet.

[0050] 5. Comprehensive monitoring system

[0051] The main functions of subway comprehensive monitoring include real-time centralized monitoring of electromechanical equipment and coordination and linkage between various systems. On the one hand, through the comprehensive monitoring system, the basic functions of real-time centralized monitoring and control of power equipment, fire alarm information and its equipment, station environmental control equipment, section environmental control equipment, environmental parameters, platform door equipment, flood prevention door equipment, escalator equipment, lighting equipment, access control equipment, automatic ticket vending and checking equipment, broadcasting and closed-circuit television equipment, and broadcast information and clock information of the passenger information display system can be realized; on the other hand, through the comprehensive monitoring system, advanced functions such as coordination and interaction between relevant system equipment in non-operating conditions at night, normal operation during the day, emergency situations, and important equipment failure situations can also be realized.

[0052] The application of the virtualized integrated control system of the integrated backup disk of the present invention includes an acquisition process and a driving process. In the actual operation process, the two processes are carried out in parallel. The two processes are described separately below. The receiving and transmitting process of the simulation platform interface middleware is omitted in the description because it is the interface middleware of the signal platform and only acts as a gateway for forwarding messages. The two processes are described below:

[0053] (1) Collection process

[0054] like Figure 3 As shown, during the operation of the system, the platform door transmits its status to the interlocking acquisition drive module and the programmable controller in real time, and the emergency stop button, area blocking button and integrated backup disk interface transmit their status to the programmable controller in real time.

[0055] When the platform door moves, the interlocking acquisition drive module will directly acquire its status, and the programmable controller will also acquire its status, and display the opening and closing status in the form of indicator lights on the integrated backup panel interface;

[0056] When the emergency stop button is pressed, the programmable controller transmits its status to the integrated backup disk drive module, which transmits it to the interlocking acquisition drive module. At this time, the train in this area will stop urgently until the emergency stop button is released;

[0057] When the area blocking button is pressed, the programmable controller transmits its status to the integrated backup disk drive module, which then transmits it to the interlocking acquisition drive module. At this time, the area is blocked, all vehicles in the area stop urgently, and vehicles outside the area are prohibited from entering until the area blocking button is released;

[0058] The programmable controller will also transmit the status of the emergency stop button and the area blocking button to the integrated backup panel interface at the same time. The integrated backup panel interface will display the status of the emergency stop button and the area blocking button in real time, allowing the platform dispatcher to monitor the status of the two devices in real time;

[0059] When the gate is in motion, the programmable controller collects its status and transmits its message to the integrated backup disk drive module, which transmits it to the integrated monitoring subsystem simulator, and then the integrated monitoring subsystem simulator transmits the message to the integrated monitoring system. The gate status will be displayed on the integrated backup disk interface and also on the integrated monitoring subsystem simulator interface;

[0060] When someone presses the button switch on the integrated backup disk interface, the programmable controller transmits its action status to the integrated backup disk drive module, and then the integrated backup disk drive module determines whether it is a signal message. If the switch button of the signal device is triggered, the information is sent to the interlocking acquisition drive module, otherwise it is sent to the integrated monitoring subsystem simulator, which then displays it on its own interface and sends the status message to the integrated monitoring system.

[0061] (2) Driving process

[0062] like Figure 4 As shown in the figure, when the train stops accurately after entering the station, the interlocking acquisition drive module sends a door opening command, the platform door opens, and when the train is ready to depart, the interlocking acquisition drive module sends a door closing command, and the platform door closes;

[0063] When the ATS (Automatic Train Monitoring System) issues a vehicle detention command, the interlocking acquisition drive module transmits the vehicle detention command to the integrated backup disk drive module, and the integrated backup disk drive module drives the programmable controller to light up the vehicle detention indicator light on the integrated backup disk interface. The interlocking acquisition drive module also transmits the route information to the integrated backup disk drive module, and updates the route status in real time on the integrated backup disk interface.

[0064] When changes occur in the integrated monitoring equipment, such as fire or elevator changes, the integrated monitoring subsystem simulator sends its status information to the integrated backup disk driver module, which then transmits it to the programmable controller and updates its status in real time on the integrated backup disk interface.

[0065] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
