Description

Technical Field

[0001] The present invention belongs to the field of integrated monitoring and control for rail transit, and particularly relates to a full-automatic verification system for urban rail transit integrated monitoring and control. Background Art

[0002] The integrated monitoring and control system for rail transit realizes centralized data collection, analysis, processing and cross-system linkage control by integrating subsystems of different professional fields (such as PSCADA, BAS, FAS, ACS, etc.). It is the system with the largest number of monitoring devices and the most data points among all systems of urban rail transit. Through data integration and linkage control, the integrated monitoring and control system improves operation efficiency, ensures safety and optimizes resource management, and plays an important role in the stable operation of rail transit.

[0003] The integrated monitoring and control discipline confirms the details of communication protocols with each subsystem through interface tests, and develops the engineering database of the system according to the point list provided by the subsystems. When the software development of the integrated monitoring and control system is completed, the professional equipment of each subsystem has not been installed yet, so on-site commissioning cannot be carried out. This stage is most suitable for the in-plant verification of the engineering database of the integrated monitoring and control system, and this verification work requires a verification system with simple operation and strong universality. The closer the functions of the verification system are to the states of the subsystem devices, the higher the accuracy of the verified integrated monitoring and control system software will be. This will avoid a large number of modifications to the integrated monitoring and control database on site during on-site commissioning, which is beneficial to improving the work efficiency of on-site commissioning and reducing labor costs.

[0004] Currently, common verification software has a single communication protocol and does not support verification of all subsystems of the integrated monitoring and control system. Its functions are simple: it can only display communication addresses and register values, cannot add information for identifying points such as point descriptions, device names and constraint conditions, only supports manual modification of register value states and cannot change them automatically. It has no statistical analysis function, so verification results need to be recorded manually. The configuration is complex, and it takes a lot of time to configure subsystems with a large number of points. Summary of the Invention

[0005] In view of the above problems, the purpose of the present invention is to provide a full-automatic verification system for verifying the point configuration, alarm function, remote control function and program control / mode control function of the integrated monitoring and control system, so as to finally improve the accuracy of point parameter configuration and the functional completeness of the integrated monitoring and control system, and reduce the work pressure of on-site commissioning personnel.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows: a full-automatic verification system for urban rail transit integrated monitoring and control is designed, which includes an ISCS system, a communication protocol module, a central processing module, a real-time interaction module, a data statistics sheet import module and a verification result output module; The ISCS system includes an ISCS human-machine interface, an ISCS database, and an ISCS communication program. The ISCS database is electrically connected to both the ISCS human-machine interface and the ISCS communication program. The ISCS database includes a real-time database, a historical database, and report data. The communication protocol module is electrically connected to the ISCS communication program and is used to verify the data of the sub-discipline; The real-time interaction module is electrically connected to the ISCS database and the central processing module respectively, and is used to read back the point values ​​in the ISCS database and send them to the central processing module. The data statistics table import module is electrically connected to the central processing module and is used to import each data table into the central processing module. The verification result output module is electrically connected to the central processing module and is used to display the verification result sent by the central processing module.

[0007] The communication protocol module integrates commonly used protocols in integrated monitoring systems, such as IEC104, MODBUS, CIP, and S7, and supports communication protocol extensions. It can be used to verify data from sub-disciplines such as PSCADA, BAS, ACS, and PSD.

[0008] The verification system provides a simple and user-friendly interface for easy operation. The data statistics import module imports sub-specialty point tables, alarm information tables, programmable cards, or pattern tables into the central processing module of the fully automated verification system using a table import method. Sub-specialty manufacturer point tables can be directly imported after simple processing, reducing the manual configuration process of the verification system. After data import, the verification system displays the point name, description, communication address, current value, and associated equipment, clearly constructing the sub-specialty equipment attributes.

[0009] The real-time interaction module is used to read back the real-time data of monitoring points in the integrated monitoring system. In the full-point automatic verification mode, the fully automatic verification system reads the corresponding point status in the integrated monitoring system before and after the point status is changed. The read-back status points are then transmitted to the central processing module, which compares the changed statuses for consistency. If the changed statuses are consistent, the point configuration is determined to be correct; otherwise, the point configuration is determined to be incorrect, and the point is recorded.

[0010] The central processing module of the verification system is the core module of the fully automated verification system, undertaking core functions such as data parsing, verification algorithm execution, result judgment, and output. Data parsing function: Different sub-disciplines may use different protocols (such as Modbus, IEC104, CIP) to transmit data. The central processing module needs to complete protocol conversion and data standardization to ensure information exchange between modules. Different verification algorithms are used to perform different verification tasks on the integrated monitoring system, including fully automated point verification, fully automated alarm verification, fully automated remote control consistency verification, and fully automated program control / mode verification. The verification steps for different verification tasks are as follows: Fully Automated Point Verification: The data statistics import module imports the sub-specialty point tables, and users manually select the communication protocol and fully automated point verification mode. After modifying the point status values, the central processing module of the verification system sends the status values ​​to the integrated monitoring system via the communication protocol module. The real-time interaction module reads back the point status values ​​from the real-time database of the integrated monitoring system once before and once after sending the status values. The central processing module compares the status values ​​and records the verification results. The verification result output module displays the total number of point configuration errors and lists all points with configuration errors.

[0011] Fully Automatic Alarm Verification: The data statistics import module imports the point table and alarm information table, allowing manual selection of the communication protocol and fully automatic alarm verification mode. After the central processing module of the verification system modifies the point status value, it sends the status value to the integrated monitoring system through the communication protocol module. Simultaneously, the real-time interaction module reads back the alarm response time, alarm level, alarm display color, and alarm sound from the historical database of the integrated monitoring system, compares the data with the alarm information table, and records the verification results. The verification result output module displays the alarm level verification results.

[0012] Automatic Remote Control Consistency Verification: The data statistics import module imports the sub-specialty point table, and the communication protocol and automatic remote control consistency verification mode are manually selected. The central processing module of the verification system modifies the point status value at the device unit level, enabling the device to have remote control rights, and sends the status value to the integrated monitoring system through the communication protocol module. The device remote control interface is manually opened in the integrated monitoring interface, and remote control information is sent. The automatic verification system changes the status of the remote signaling point corresponding to the remote control and reads back the remote signaling point status value from the real-time database in the integrated monitoring system through the real-time interaction module. After data comparison, the verification result is recorded. The verification result output module displays the total number of remote control configuration errors and lists the device information with configuration errors.

[0013] Automatic Verification of Programmable Control / Mode: The verification process for programmable control commands or mode control commands is consistent; the example given is programmable control. The data statistics import module imports the sub-specialty point table and programmable control cards, and the communication protocol and automatic verification mode for programmable control / mode are manually selected. The fully automatic verification system prompts for the programmable control cards to be verified; the corresponding programmable control commands are manually issued on the integrated monitoring interface as prompted. After receiving the programmable control commands, the central processing module of the verification system modifies the point status values ​​of the corresponding devices according to the programmable control cards and sends the status values ​​to the integrated monitoring system through the communication protocol module. Simultaneously, it reads back the point status values ​​from the real-time database in the integrated monitoring system through the real-time interaction module, compares the data, and records the verification results. The verification result output module displays the total number of programmable control point configuration errors and lists all points with configuration errors.

[0014] The present invention also provides a verification method based on the above-mentioned fully automatic verification system, comprising the following steps: Step S1: Sub-specialty data is imported into the central processing module through the data statistics table import module, then the communication protocol and verification mode are selected, and the verification system service program is started; Step S2: The integrated monitoring front-end unit requests access data from the fully automatic verification system. The communication protocol module of the fully automatic verification system responds to the access request and sends the value of the corresponding address device status point to the integrated monitoring system front-end unit. Step S3: The integrated monitoring front-end unit sends the collected data to the integrated monitoring server. The integrated monitoring server processes the data and changes the real-time database point values. At the same time, it stores the points whose status or values ​​have changed into the historical database. Step S4: The integrated monitoring workstation reads the values ​​from the real-time database of the integrated monitoring server and presents them to the user in the form of dynamic images; Step S5: Before and after executing S2, the fully automatic verification system requests the values ​​in the real-time database from the integrated monitoring server through the real-time interaction module, and transmits the read-back status points to the central processing module, which compares whether the change statuses are consistent. If the change statuses are consistent, it is determined that the point configuration is correct; otherwise, it is determined that the point configuration is incorrect and the point is recorded. Step S6: After the central processing module of the fully automatic verification system completes the recording, the verification result output module displays the total number of point configuration errors on the display terminal and lists all points with configuration errors; thus completing this fully automatic verification.

[0015] Compared with the prior art, the present invention has the following advantages: (1) The present invention has a universality, simple operation and more comprehensive verification and monitoring system, which can improve the accuracy and stability of the integrated monitoring system and improve the efficiency of on-site integrated commissioning.

[0016] (2) Using this verification system to perform point-to-point verification on the integrated monitoring system can effectively detect problems such as register address errors, model errors, and dialog box errors; it effectively improves the accuracy and practicality of the integrated monitoring system and reduces the workload of on-site debugging personnel.
