车载两用显示器抗扰度测试方法

Analysis test method for electrical disturbances feature of road vehicle dual-use monitor

通过对比国内现行的抗扰度测试标准GB/T17618-1998、GB/T17619-1998和国际上普遍使用的ISO11452《道路车辆电气电子部件对窄带辐射电磁能的抗扰性试验方法》之间的差异,提出ISO11452标准中的电波暗室法为基础,结合产品本身性能进行车载两用显示器抗扰度的测试方法,并用该方法和GB17618-1998分别对一组产品进行测试、比较,同时分析测试中产品性能降低的原因,提出整改方法。验证了该方法适合于车载两用显示器抗扰度性能测试。

The paper analyzed the difference among the National Standard, as GB/T17618-1998, GB/T17619-1998 and ISO standard as ISO 11452. Proposed a test method for testing electrical disturbances feature of road vehicle dual-use monitor, which used ISO11452- Absorber-lined shielded enclosure combined with the feature of the dual-use product. The paper explained the approach of this test method. Verified the validity of this test method by the way of contrasting the test results of samples tested under this method and under GB17618-1998. And analyzed the test results , gave modified ways to improve the performance of the product .
