针对机车用压力传感器的主要干扰源与耦合途径,提出电磁兼容设计改进措施,不仅改善了传感器电磁兼容性能,而且提升了传感器的耐压等级。按照TB/T 3221进行电磁兼容测试,测试结果符合传感器整体误差要求,说明所提出的电磁兼容设计正确、有效。该电磁兼容设计对机车上其他电子设备的电磁兼容设计同样具有参考价值。
Aimed at the main interference sources and coupling ways of locomotive pressure sensors, the improvement measures of EMC design are proposed, which not only improve the EMC performance of the sensors, but also improve the pressure rating of the sensors. According to TB / T 3221 electromagnetic compatibility test, the test results in line with the overall error of the sensor requirements, indicating that the proposed EMC design is correct and effective. The electromagnetic compatibility design of the other electronic equipment on the motorcycle electromagnetic compatibility design also has a reference value.
