CANstressD and CANstressDR

CANstressD 和 CANstressDR:网络干扰

CAN网络本身对总线通信干扰和通信失败有着比较强的抗干扰性。为了测试系统在扰乱或者失败的状态下能否正常的工作,所以需要一种用于干扰CAN总线的设备,它能在一个有针对性的,并可重复的物理性能和逻辑层(显性或隐性)工作。CANstressD(数字)或者CANstressDR(数字和电阻)是CAN开发人员可以使用的综合性干扰仪。

特点和优势:

CANstress is a standalone hardware module that is inserted directly onto the CAN bus. It contains various triggering conditions and disturbance logics. The fully equipped module includes a number of resistors that can be software-controlled. These resistors are used to force different bus levels onto the bus lines by limiting the voltage supplied.

功能:

  • 模拟线路故障
  • CAN系统故障
  • 贯穿着电子控制单元开发测试的所有阶段
  • CAN控制器的干扰
  • 可编程短路和中断

可以通过总线内置的可编程静态电容来模拟各种线缆的长度。
