Nuclear power station safety level instrument control system

Abstract

The invention discloses a nuclear power station safety level instrument control system comprising a case; the case comprises a first board card; the first board card comprises an ASPLD chip, a backboard communication control module in the ASPLD chip is used for unpacking input data and storing the data in a cache of the ASPLD chip, then packing the data according to a backboard communication data format, sending the data to the outside of the nuclear power station safety level instrument control system frame by frame; a comparison module is used for comparing the unpacked input data with configuration parameters to obtain a comparison result; and a calculation module is used for calling an operation interface to operate the comparison result and outputting an operation result. According to the invention, the backboard communication control module in the ASPLD chip carries out unpacking storage or packaging sending processing on the received input data, a plurality of operation interfaces are integrated on the calculation module, and the operation interfaces on the calculation module are called to carry out operation on the comparison result and output the operation result, so that the processing energy efficiency is improved, and the resource occupation space is saved.

Description

Technical field [0001] The present invention relates to the field of safety grade instrument, and in particular, to a nuclear power plant security system control system. Background technique [0002] FPGA (programmable logic gate array) technology is a structured implementation, is a hardware reconstructed architecture, with powerful computing power and flexibility, different from CPU (central processor) serial description , The serial description of the CPU needs to be executed by the operating system instruction decoding, but also a shared memory. Since the memory of the serial description of the CPU is shared, you need to do access arbitration. In order to use the limitations of access, the consistency of the cache component is required, resulting in low energy efficiency. And the operating system and application software of the CPU processor are not open to the applicant, and only black box tests can not be made. Inventive content [0003] The technical problem to be solved ...
