DS4330 LIN Interface Board1)

LIN 总线接口

通过DS4330 LIN Interface Board,您可以将dSPACE系统连接到LIN(Local Interconnect Network)通信系统。dSPACE 系统可以对 LIN 总线连接的 LIN 节点进行仿真。所仿真的 LIN 节点的行为与真实总线节点完全相同(残余总线仿真)。

The end of life for this product has been set. Please see the footnote for more detailed information.

在快速控制原型开发中的应用领域

DS4330 和相应软件可以用来开发和测试能与 LIN 执行器和传感器通信的电子控制单元 (ECU)。对于基于实验室或基于车辆的快速控制原型开发,真实 LIN 从节点可以连接到原型系统,该系统将开发中的 ECU 作为主节点进行仿真。

硬件在环仿真中的应用领域

用户可以使用 dSPACE Simulator和 DS4330 测试电子控制单元的 LIN 网络功能。dSPACE 系统可以对 LIN 总线连接的 LIN 节点进行仿真。所仿真的 LIN 节点的行为与真实总线节点完全相同(残余总线仿真)。

测试方案

DS4330 具有许多不同的使用方式。以下是几种可能的测试方案:

  • 测试消息帧的传输
  • 测试通信计时限制
  • 测试规格限制
  • 测试诊断状况和故障状况
  • 测试节能模式

全面的软件支持

DS4330 含有一个 LIN 接口,用于将 dSPACE 系统连接到 LIN 总线。您可以使用 RTI LIN MultiMessage 模块组来设置和控制这些仿真的 LIN 总线。

RTI LIN MultiMessage Blockset(支持 LIN 标准 1.3、2.0 和 2.2)能够扩展Real-Time Interface,且可用于将 dSPACE 系统与 LIN 通信网络结合,并能用于配置这些 LIN 网络。借助于 RTI LIN MultiMessage Blockset,您可以处理复杂的 LIN 设置,从而能够利用单个 Simulink ®模块控制并配置所有的无条件 LIN 帧和事件触发的 LIN 帧(通过数据库文件进行配置)。

1)The end of life of the dSPACE PHS (peripheral high-speed) hardware for modular systems is planned for December 31, 2024. You can still buy the related products up to and including December 31, 2021. New Releases of dSPACE software will still support the dSPACE PHS hardware for modular systems until at least the end of 2023. After the end of life, no services of any kind will be available for these products. We advise against using the PHS hardware products in new projects. For new projects we recommend that you use SCALEXIO, the latest dSPACE technology for modular real-time systems.
