摘要
针对LED光源产品电特性参数测试项目多、采用人工方法、测试过程数据不可溯源的问题,提出研制LED光源电特性单工位多参数综合测试装置,利用动态数据交换(DDE)技术在线控制PLC切换测试线路,并记录电参数测量仪测量的电参数数据,实现测试自动化及测试数据可溯源。通过实验对比表明,该装置能完全按照测试规范进行LED多项电特性参数自动测试,实现机器代人与测试数据全溯源。
To solve the problems in the test of electrical parameter of lighting LED module, such as redundancy of test items, relying on manual test and untraceable test process data, a synthetic detection device with single-stage and multi-parameters of lighting LED electrical characteristic is developed in this paper. Using the technology of dynamic data exchange(DDE) to control the PLC to switch the device's circuits online and record the electrical parameter data by an electrical parameter measuring instrument, the device can realize automatic tests and full data recording and tracing. The experimental comparisons show that the test device can proceed automatic tests of LED multiple electrical parameter completely following the test standard and realize the replacement of human by device and full data recording and tracing.
