For a leading manufacturer of home automation equipment, we developed a universal test system to Test complete product families of jalousie and dimmer applications.
This test system includes In-Circuit Test, flashing of the DUTs and complete Functional Test. Additionally, the build-in RGB LEDs are calibrated in color and brightness.
This test system has been developed to perform production tests of all families of offered switches, switching clock timers, jalousie switches, dimmers and several displays. The customer emphasizes primarily a high accuracy of the color balancing of the used RGB LEDs. All possible colors of all diodes are measured and balanced so that the human eye can ‘t notice any difference in color and brightness.
CPU programming has been carried out with several different flash programming devices. Controlling of these devices has been done using software, written in the graphical programming language NI LabVIEW. The used ABex® system guarantees high signal quality due to wireless signal routing and freely configurable switching of all devices onto the integrated bus system.
The test system is based on the PXI platform using the ABex® system extension.
Using this test system in the SMD production line, the customer can now automatically test more than 50 different applications with several different test adapters in three-shift work. The system is maintenance free and can be used without high training efforts.
Without programmatic changes the customer can integrate new test adapters by themselves in a very simple manner because all instruments and devices are used in multiple configurations.
Due to the high variety of applications the customer uses several identical test systems in its production floor. All test systems are built identically and can test the whole product portfolio. The test programs, parameter sets and limits are provided from the network and can be used from all test systems without redundant data management of the DUTs and complete functional test. Additionally, the build-in RGB LEDs are calibrated in color and brightness
