Communication redundant rod position detection device

Abstract

The present application discloses a communication redundant rod position detection device which comprises a host machine for generating an information collection control instruction, a rod position detector for detecting the depth position of a control rod in a nuclear reactor, communication equipment which comprises N communication devices and sets any communication device which can normally work in the N communication devices as a main communication device, wherein N is an integer which is not smaller than 2. The main communication device is connected to the rod position detector and the host machine such that the depth position information corresponding to the detection signal of the rod position detector is uploaded to the host machine. The communication equipment comprises N communication devices, when any one communication device in the communication equipment is failed, other communication devices which can normally work in the communication equipment can be set as the main communication device, the data communication interruption can be avoided, the reliability of the rod position detection device is improved, and thus the safety of the nuclear reactor is improved.

Description

technical field [0001] The invention relates to the technical field of rod position detection, in particular to a communication redundant rod position detection device. Background technique [0002] At present, when the nuclear reactor is working, it is necessary to control the rate of the chain reaction by adjusting the insertion depth of the control rods, so as to ensure the controllability of the nuclear reactor as much as possible. Therefore, it is necessary to strictly detect the position information of the control rods. [0003] However, the only communication device in the existing rod position detection device is prone to failure after being used for a period of time, resulting in the information detected by the rod position detector not being uploaded to the host computer smoothly, so that the host computer and the staff cannot know the rod position. The specific information of the nuclear reactor has seriously affected the safety of the nuclear reactor. [0004] F...
