A communication transmission device for heavy water reactor control system

Abstract

The invention discloses a communication transmission device for a heavy water reactor control system, which relates to the field of nuclear power plant control systems, including: a virtual state register module, used to receive read and write request operation instructions transmitted between the heavy water reactor control system and peripheral terminal equipment; The read and write request logic module is used to control the high and low level signals of the flip-flop according to the read and write request operation instructions, and lock the idle buffer; the virtual protocol conversion module is used to convert the bus protocol; the virtual data buffer module is used to convert The state data to be read and written is read into the idle buffer, and it is transmitted bidirectionally between the parallel interface and the virtual protocol conversion module; the virtual interrupt generation logic module is used to generate an interrupt pulse when the high-low level signal is switched, and The interrupt pulse is bidirectionally transmitted between the parallel interface and the virtual protocol conversion module. Realize the data communication between the heavy water reactor control system and the PC terminal.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant control systems, in particular to a communication transmission device for a heavy water reactor control system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the heavy water reactor nuclear power plant control system, the industrial computer is connected through the parallel bus to send and receive and control the nuclear power signal. When communicating with the industrial computer through the parallel bus, a board with parallel interface and PCIe interface conversion function is required for nuclear power equipment. . [0004] However, due to the inconsistent protocol standards of each bus, such as the PCIe communication protocol currently used on the computer side, due to the incompatibility of the communication protocol and the irregularity...

Problems solved by technology

[0004] However, due to the inconsistent protocol standards of each bus, such as the PCIe communication protocol currently used on the computer side, due to the incompatibility of the communication protocol and the irregularity of the signals on the parallel bus of the main control system of the heavy water reactor, it is some messy Therefore, the computer cannot be directly connected to the communication interface of the main control system of the heavy water reactor, and the main control system of the heavy water reactor cannot directly communicate with the PCIe interface on the computer side, so there is a lack of communication between the main control system of the heavy water reactor nuclear power plant and the computer. function, and there is no related interface connection scheme
