Abstract

The invention relates to a CAN communication transmission method in a nuclear radiation environment. An anti-radiation CAN communication module involved in the method is composed of a processor, a first relay, a second relay, a third relay, a first CAN communication chip, a second CAN communication chip, a third CAN communication chip, a grounding end, a power supply end, a data receiving end, a data sending end, a high potential transmission end and a low potential transmission end. When the anti-radiation CAN communication module is used, the anti-radiation CAN communication module is placedin a radiation field, all ports are connected according to requirements, normal connection is ensured, a 50Rad(Si) / s dose rate is adopted for testing, and a communication test is carried out. Test results prove that the anti-radiation CAN communication module can normally work in a nuclear radiation environment, meets design requirements and can be applied to remote data signal transmission in the nuclear radiation environment.

Description

technical field [0001] The invention relates to the technical field of communication transmission in a radiation environment, and uses a radiation-resistant CAN communication module for remote transmission of information in a nuclear radiation environment. Background technique [0002] In nuclear power plants, various information of core parts (inside containment, pressure vessels, etc.) This environment has the effect of nuclear radiation, which will have a huge impact on semiconductor devices, causing errors or even permanent damage to devices. The current CAN communication chip can only work for a short period of time in a nuclear radiation environment, and then it will fail. At present, there is an urgent need for a solution for remote transmission of data information. [0003] Based on the above description, in order to solve the existing problem of remote data information transmission in a nuclear radiation environment, the present invention provides a method for rem...
