Description

TECHNICAL FIELD

[0001] The present application relates to the field of IFIX, in particular to an operator IFIX sound alarm method with scalable adaptation. BACKGROUND

[0002] IFIX is the world's leading HMI / SCADA automation monitoring configuration software, although the GE-IFIX human-computer interface software has a sound alarm function, but the GE-IFIX human-computer interface software itself lacks secondary development function, and the developer cannot modify the internal business. For example: the alarm sound cannot be changed; the process point cannot be combined with logic alarm; the alarm point cannot be selectively displayed by process section; the historical alarm information cannot be traced, etc., and the addition, deletion, query and modification of the alarm can only rely on professional technical personnel to implement, and the operator cannot operate independently. And the PIMS / MES system excessively depends on the OPC data interface, and the interface exception or data blocking function is invalid and difficult to find, in addition, there is a certain delay in data transmission, and the alarm triggering has the risk of not being timely, and because the OPC interface of the factory DCS generally bears other functions (such as material information flow), the addition of the alarm information point increases the interface interaction burden in recent years.

[0025] S1, cache the process data requiring alarm function to a third-party database; wherein the process data requiring alarm function comprises the position number of the process instrument or device point position requiring alarm function and alarm judgment logic. The process data cache is realized by pre-deploying the third-party database, the original IFIX data secondary development limitation is avoided, and subsequent function implementation is carried out. The third-party database is an Access database.

[0026] S2, remotely transmit real-time process data on site, and transmit the real-time process data to a PLC processor of a DCS system through an analog electric signal or Profibus-DP for processing; wherein the real-time process data comprises a process instrument / device process real-time value.

[0027] S3, the PLC processor samples the analog electric signal into a digital signal, converts the digital signal into a process numerical value format, and then transmits the process numerical value format to an IFIX SCADA server;

[0028] S4, a server-side software calls an IFIX data interface through Microsoft Visual Studio (C#), reads real-time process data from the IFIX SCADA server according to the Access database preset point position name in a cycle, and saves the real-time process data. Since the access period between the SCADA and the PLC is in seconds, the Access database data refresh rate and throughput are much greater than those of the PIMS database, and the timeliness requirement of the alarm is met.

[0029] S5, the server-side software is according to the precast in Access database each data point alarm judgment logic, combine real-time process data value, constantly refresh Access database each point alarm state.

[0030] S6, the client accesses the third-party database shared by the server through the OleDB data interface through the event triggering / timing mechanism, detects whether each point has an alarm, and if there is an alarm, calls the Windows API to play the preset WAV alarm music, and displays the current alarm on the client software window.

[0031] Adopt C / S architecture to independently develop software, no longer limited to IFIX built-in functions and secondary development closed restrictions.In addition, since the software and the database are deployed in the DCS intranet environment, and isolated from external devices or networks, the information security of the DCS system is guaranteed from the physical layer.

[0032] S7, since the Access database is pre-installed with user accounts and permission levels, the operator logs in to the client software through the Winform interface, and the software checks the login password of the login account and obtains the permission information.

[0033] S8, the client software has a plurality of alarm WAV files, and the authorized operator can select the alarm sound file independently.The defect that IFIX5.5 software can only fix one kind of alarm sound is solved.At the same time, the operator can realize the addition, deletion, query and modification of the alarm point, alarm logic and level in the database through the graphical interface.Since the Access database and the IFIX SCADA database are isolated, the security restriction that the IFIX point alarm attribute can only be modified by the DCS technician is avoided.

[0034] S9, in order to meet the statistical requirements of stages, such as monthly / quarterly statistical requirements, the operator can browse the alarm point report through the client window, export data through the VS2010 report plug-in and view the alarm distribution / operation log function.

[0035] The application can effectively avoid the delay problem of similar OPC interface by directly reading the process / equipment data from the server side through the data interface provided by GE-IFIX.The operator will immediately discover from the control room if the server runs abnormally.The IFIX data read is stored in the third-party database of the historical server, and the client is read by C#, alarm point combination logic, historical record and operator addition, deletion, query and modification function are realized.
