为了解决核辐射应用场景里数字脉冲幅度分析模块在使用过程中CAN总线数据传输速率低的问题，设计了一款RJ45网络与CAN总线的透明传输模块。详细介绍了传输模块的硬件和软件设计，并通过基于QT平台开发的上位机软件进行实际测量，实现了能谱数据滤波显示。实验表明，RJ45网络与CAN总线的透明传输模块实现了两种不同通讯方式的跨接，保证了数据的可靠性，提高了数字脉冲幅度分析仪的传输速率。
In order to solve the problem of low CAN bus data transmission rate dur-ing the use of the digital pulse amplitude analysis module in nuclear radiation application scenari-os, a transparent transmission module of RJ45 network and CAN bus was designed. The hardware and software design of the transmission module are introduced in detail, and the actual measure-ment is carried out through the upper computer software developed based on the QT platform, and the energy spectrum data is filtered and displayed. Experiments show that the transparent trans-mission module of the RJ45 network and the CAN bus realizes the bridging of two different commu-nication methods, which ensures the reliability of the data and improves the transmission rate of the digital pulse amplitude analyzer.
