Description

TECHNICAL FIELD

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

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

[0003] The integrated monitoring professional confirms the communication protocol details with each subsystem through interface testing, and develops the engineering database of the system according to the point table provided by the subsystem. When the integrated monitoring system software development is completed, the installation of professional equipment of each subsystem has not been completed, and on-site debugging cannot be performed. This stage is most suitable for the factory verification of the engineering database of the integrated monitoring system, and this verification work requires a verification system that is simple to operate and has strong versatility. The closer the function of the verification system to the state of the subsystem equipment, the higher the accuracy of the verified integrated monitoring system software. This will avoid a large number of modifications to the integrated monitoring database on site during on-site debugging, and is intended to improve the efficiency of on-site debugging and reduce personnel costs.

[0004] The commonly used verification software currently has a single communication protocol and does not support verification of all subsystems of the integrated monitoring system. The function is simple and can only display the communication address and register value, cannot add point description, device name, constraint condition and other information for easy identification of points, only supports manual modification of register value state, cannot automatically change, does not have statistical analysis function, needs to manually record verification results, and configuration is complex, which requires a lot of time to configure the subsystem with a large number of points. SUMMARY

[0005] In view of the above problems, the purpose of the present application is to provide a full-automatic verification system for verifying the database point configuration, alarm function, remote control function and program control / pattern control function of the integrated monitoring system, so as to ultimately improve the accuracy of the point parameter configuration and the integrity of the function of the integrated monitoring system, and reduce the work pressure of the on-site debugging personnel.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: a full-automatic verification system for urban rail transit integrated monitoring is designed, which comprises an ISCS system, a communication protocol module, a central processing module, a real-time interaction module, a data statistical table import module and a verification result output module. The ISCS system comprises an ISCS man-machine interface, an ISCS database and an ISCS communication program, the ISCS database is electrically connected with the ISCS man-machine interface and the ISCS communication program respectively; the ISCS database comprises a real-time database, a historical database and a report data; The communication protocol module is electrically connected with the ISCS communication program and is used for checking data of a sub-professional; The real-time interaction module is electrically connected with the ISCS database and the central processing module respectively and is used for reading back point values in the ISCS database and sending the point values to the central processing module; The data statistical table import module is electrically connected with the central processing module and is used for importing each data table to the central processing module; The checking result output module is electrically connected with the central processing module and is used for displaying the checking result sent by the central processing module.

[0007] The communication protocol module integrates commonly used protocols of the integrated monitoring system, such as IEC104, MODBUS, CIP and S7, and supports communication protocol expansion, and can be used for checking data of PSCADA, BAS, ACS, PSD and other sub-professionals.

[0008] The checking system provides a simple and friendly operation interface, which is convenient for users to operate. The data statistical table import module imports the point table, alarm information table, program control card or mode table of the sub-professional into the central processing module of the full-automatic checking system in the form of table import. The point table of the sub-professional manufacturer can be directly imported after simple processing, which reduces the process of manually configuring the checking system. After the data is imported, the checking system displays the point name, description, communication address, current value and the belonging equipment, and clearly constructs the equipment properties of the sub-professional.

[0009] The real-time interaction module is used for reading back the point values in the real-time database of the integrated monitoring system. In the full-point automatic checking mode, the integrated monitoring system reads the corresponding point states before and after the change of the point state of the full-automatic checking system. The read-back state points are transmitted to the central processing module, which compares the change states to determine whether they are consistent. If the change states 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.

[0010] The central processing module of the checking system is the core module of the full-automatic checking system, which bears the core functions of data analysis, checking algorithm execution, result determination and output. The data analysis function: different sub-professionals may use different protocols (such as Modbus, IEC104, CIP) to transmit data, and the central processing module needs to complete protocol conversion and data standardization to ensure information exchange between modules. Through different checking algorithms, different checking contents of the integrated monitoring system are realized, including point full-automatic checking, alarm full-automatic checking, remote consistency full-automatic checking, and program control / pattern full-automatic checking. The checking steps of different checking contents are as follows: Point full-automatic checking: the data statistical table import module imports the sub-professional point table, and manually selects the communication protocol and point full-automatic checking mode. The central processing module of the checking system modifies the point state value and sends it to the integrated monitoring system through the communication protocol module. The real-time interaction module reads the point state value in the real-time database of the integrated monitoring system once before and after sending the state value. The central processing module compares the state values and records the checking results. The checking result output module displays the total number of point configuration errors and lists all the points with configuration errors.

[0011] Alarm full-automatic checking: the data statistical table import module imports the point table and alarm information table, and manually selects the communication protocol and alarm full-automatic checking mode. The central processing module of the checking system modifies the point state value and sends it to the integrated monitoring system through the communication protocol module. At the same time, the real-time interaction module reads the alarm response time, alarm level, alarm display color, and alarm sound in the historical database of the integrated monitoring system, and compares them with the alarm information table to record the checking results. The checking result output module displays the alarm level checking results.

[0012] Remote consistency full-automatic checking: the data statistical table import module imports the sub-professional point table, and manually selects the communication protocol and remote consistency full-automatic checking mode. The central processing module of the checking system modifies the point state value of the device unit to make the device have remote control rights, and sends the state value to the integrated monitoring system through the communication protocol module. The remote control interface of the device is manually opened on the integrated monitoring interface, and the remote control information is sent. The full-automatic checking system changes the remote signaling point state corresponding to the remote control, and reads the remote signaling point state value in the real-time database of the integrated monitoring system through the real-time interaction module. After data comparison, the checking results are recorded. The checking result output module displays the total number of remote control configuration errors and lists the device information with configuration errors.

[0013] Program control / mode automatic verification: program control command or mode control command verification process is consistent, for example, program control is explained. Data statistics table import module imports sub-professional point table, program control card, manually selects communication protocol, program control / mode automatic verification mode. The full-automatic verification system prompts the program control card to be verified, and the corresponding program control command is manually issued in the integrated monitoring interface according to the prompt. After the central processing module of the verification system receives the program control command, the point value of the corresponding device is modified according to the program control card, and then the state value is sent to the integrated monitoring system through the communication protocol module. At the same time, the real-time database point value in the integrated monitoring system is read back through the real-time interaction module, and the data is compared to record the verification result. The verification result output module displays the total number of program control point configuration errors, and lists all the point configuration errors.

[0014] The application also provides a verification method based on the full-automatic verification system, comprising the following steps: Step S1: The sub-professional data is imported into the central processing module through the data statistics table import module, and then the communication protocol and the verification mode are selected, and the verification system service program is started; Step S2: The integrated monitoring front-end machine requests access data from the full-automatic verification system, and the communication protocol module of the full-automatic verification system responds to the access request and sends the corresponding address device state point value to the integrated monitoring system front-end machine; Step S3: The integrated monitoring front-end machine sends the collected data to the integrated monitoring server, and the integrated monitoring server changes the real-time database point value after processing the data, and stores the points with changed state or value in the historical database; Step S4: The integrated monitoring workstation reads the value in the real-time database of the integrated monitoring server, and presents it to the user in the form of a dynamic picture; Step S5: The full-automatic verification system respectively requests to read the value in the real-time database through the real-time interaction module before and after executing S2, and transmits the read state point to the central processing module, which compares whether the changed state is consistent; If the changed state is 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 full-automatic verification system records, the verification result output module displays the total number of point configuration errors on the display terminal, and lists all the point configuration errors; Complete the full-automatic verification.

[0023] The real-time interaction module is used to read back the point value of the real-time database of the integrated monitoring system. In the full-point automatic check mode, the full-automatic check system reads the corresponding point state in the integrated monitoring system before and after changing the point state. The read-back state points are transmitted to the central processing module, which compares the change state to determine whether the point configuration is correct. If not, it is determined that the point configuration is incorrect and the point is recorded.

Different check algorithms are used to realize different check contents of the integrated monitoring system, including point full-automatic check, alarm full-automatic check, remote consistency full-automatic check and program control / mode full-automatic check. The check steps of different check contents are as follows: Point full-automatic check: the data statistics table import module imports the sub-professional point table, and manually selects the communication protocol and point full-automatic check mode. The central processing module of the check system sends the state value to the integrated monitoring system through the communication protocol module after modifying the point state value.

Open the device remote control interface on the integrated monitoring interface manually, and issue remote control information. The automatic check system changes the remote signal point state corresponding to the remote control, and reads the remote signal point state value in the real-time database of the integrated monitoring system through the real-time interaction module. After comparing the data, the check results are recorded. The check result output module displays the total number of remote control configuration errors and lists the device information of the configuration errors.

[0027] Program control / mode automatic check: the program control command or mode control command check process is consistent.

[0031] Step S3 belongs to the data interaction process within the integrated monitoring system. The integrated monitoring front-end sends the collected data to the integrated monitoring server, and the integrated monitoring server changes the point values in the real-time database after processing the data, and meanwhile stores the points with changed states or values into the historical database.

[0032] Step S4 belongs to the data interaction process within the integrated monitoring system. The integrated monitoring workstation reads the values in the real-time database of the integrated monitoring server, and presents the values to the user in the form of dynamic pictures.
