Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] Such as figure 1 As shown, the nuclear power plant whole plant DCS portable debugging device of the present invention comprises:
[0035] (1) A simulation model host, responsible for:
[0036] ●Run the simulation model; simulate each physical system in the nuclear power plant, that is, the control object of DCS;
[0037] ●Data communication between I / O data acquisition modules;
[0038] ●Run debugging engineering console software to control the DCS debugging process;
[0039] ●Configure and debug the initial conditions and run the IOMAP (IO mapping) software for communication. This software distributes the data obtained through the I / O data acquisition module to each simulation model, and at the same time collects the data obtained by each simulation model through I / O data acquisition. module output;
[0040] In this embodiment, a simulation...

The invention belongs to the technical field of nuclear power DCS debugging, in particular to a portable DCS debugging device and a debugging method for the whole plant of a nuclear power plant. The device includes: a simulation model host, an I / O interface system, and a shell; the simulation model host runs a simulation model and an IO mapping system, and the simulation model includes a physical system model controlled by the DCS in a nuclear power plant and a model of the DCS itself, and the IO mapping system will The parameters of the simulation model correspond to the input and output signals of the I / O interface system; the I / O interface system includes: the I / O interface module, the TA module connecting the I / O interface module with the real DCS, the simulation model host and the I The I / O interface module is a communication module for communication; the TA module is a cable structure; the I / O interface module and the communication module are fixed on the shell. Said method uses the nuclear power plant whole plant DCS portable debugging device as claimed in claim 1. The invention can make up for the defect that the traditional debugging method cannot simulate the closed-loop control, and can fully verify the correctness of the DCS logic.
Description
technical field [0001] The invention belongs to the technical field of nuclear power DCS debugging. Background technique [0002] In the nuclear power plant operating system, the nuclear power DCS (digital control system, digital control system) is the control part of the entire operating system and belongs to the core technology. Its performance is directly related to the operating efficiency of the nuclear power plant, and its stability and fault tolerance are directly related to the nuclear power plant Safe to use. Before a nuclear power plant is put into operation, the DCS must be fully commissioned and tested. In the prior art, using real objects for debugging means that the DCS and the controlled objects of the DCS need to be run at the same time. In this way, it takes a lot of materials and time, and it is easy to cause damage to the equipment; at the same time, due to the limitations of physical testing, It is difficult to test the working state of DCS in extreme c...
