Real-time Chinese soft light sub-board alarm and digital display device for thermal power generating unit

Abstract

The invention relates to a thermal power generating unit real-time Chinese soft light token alarm and digital display device which comprises a CNET token ring network, an ICI03 module interface assembly, an SCSI port, an ALTHORN server and a client, in the CNET token ring network, the INICI03 module interface assembly is adopted as a node on a CNET loop, and the SCSI port is connected with the CNET loop. An SCSI port is connected with an ALTHORN server hung in a local area network in a factory or an independent network, an ALTHORN communication protocol technology is adopted, a client or otherservers of a client read real-time production process values in the ALTHORN server through the network, functions achieved by client software are completed, the ALTHORN communication protocol technology is adopted. The reliability of data communication is ensured, the real-time performance is high, the stability is high, the disk storage process logic of the ALTHORN server, the RUNTIME module realizes real-time production process numerical value and software window design of a client, the maintenance amount can be reduced, the operation is simple, and the interface is friendly.

Description

technical field [0001] The invention relates to the technical field of industrial application software, in particular to a real-time Chinese soft-photonic sign alarm and digital display device for a thermal power unit. Background technique [0002] semAPI (The Strategic Enterprise Management Application Programming Interface) is an application programming interface function library used to realize the communication between the client computer and the ICI module group. It mainly includes two parts, the function library and the device driver (DEVICE DRIVER). The application program developed by the user can complete the reading and writing operation of the C_NET loop value by calling the corresponding library function in the development environment of C language. . [0003] Usually, the application software provided by the ABB SYMPHONY DCS control system to engineers only provides functions such as DCS logic and screen configuration, that is, DCS manufacturers only provide ap...

Problems solved by technology

[0003] Usually, the application software provided by the ABB SYMPHONY DCS control system to engineers only provides functions such as DCS logic and screen configuration, that is, DCS manufacturers only provide application-level software that meets general maintenance work, and cannot provide real-time reading and calling of DCS data, etc. The software at the development level is for users to use, that is, the manufacturer does not provide (and does not have) advanced (development) applications. Therefore, the openness of the ABB SYMPHONY DCS control system is very poor. It is very difficult for users to directly read the internal data of DCS. To obtain DCS real-time data, only self-programming and development

[0004] For programming and development to obtain the six most commonly used data types of ABB SYMPHONY DCS, we define each data type as an array structure, and each array structure contains a variety of data, including Boolean, integer, floating Point type (double precision), character type (string), etc., using this array structure can accurately represent the actual data structure of DCS, but these array structures bring great difficulties to data transmission. At present, the industrial control application field is still There is no open protocol that can use these array structures to transmit data. Therefore, it is of great significance to invent a data communication exchange protocol that satisfies the transmission of this array structure.

[0005] With the continuous progress of society and the rapid development of modern computer technology and network technology, the design of the main control room of thermal power plants is more and more simple and beautiful. requirements, while the disadvantages of the traditional hard photon brand alarm window, such as poor reliability and stability and large maintenance, are becoming more and more prominent, and do not meet the requirements of new technology development. To develop a new type of real-time Chinese software for thermal power units Photonic alarm and digital display devices are becoming more and more important
