Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 Shown is the connection block diagram of the DCS automatic test device based on virtual instrument of the present invention and the DCS system to be tested, wherein the DCS system to be tested is a DCS digital control system used in a nuclear power plant control system. From figure 1 It can be seen from the middle right part that the DCS automatic test device based on virtual instrument includes a computer module as the control equipment, and a group of virtual instrument modules as the execution equipment of the test. The virtual instrument module mainly includes two groups of sub-modules: a group of data acquisition / output modules and a set of communication modules. While the device has developed test methods for different test items, it has also developed a test process management method to manage various tests a...

Abstract

The invention belongs to the technical field of nuclear power automation tests, and relates to a DCS automation test device based on a virtual instrument. The device comprises a computer module as a control device and a virtual instrument module as an execution device of the test, the virtual instrument module comprises a data acquisition/output module and a communication module, the data acquisition/output module processes three kinds of signals including signals output to the test device by a DCS, signals output to the DCS by the test device, and DCS two-layer display image grayscale acquisition/screen touch signals, and the communication module comprises a network communication unit and an industrial field bus communication unit. According to the device, the one-layer logic function andthe two-layer display function of the DCS system and the communication function between DCS devices can be tested, and defects of insufficient test tool resources and single function of the conventional nuclear power station DCS are overcome.

Description

technical field [0001] The invention belongs to the technical field of nuclear power automatic testing, and relates to a DCS automatic testing device based on a virtual instrument. Background technique [0002] With the country's increasingly urgent demand for fully independent nuclear power products, my country's independent third-generation nuclear power DCS control system has emerged as the times require, and the product line has been continuously enriched. Therefore, the demand for related tests, system integration, and functional testing of nuclear power DCS systems continues to increase. Since the third-generation nuclear power DCS system has the characteristics of large scale, rich types of processing signals, and high processing accuracy, higher requirements are put forward for its related test equipment. The mode of traditional test computer control system discloses a kind of function test system as Chinese patent CN200610122360, it is characterized in that: compri...
