Elevator light curtain test stand
CABR JDGM - V2.0 elevator light curtain test-bed is set data acquisition, data processing, motion control, display and report printing, etc as a whole, is suitable for the production, design, development, and testing the screen test platform.
I. Main functions
This test bed can be used for the following experiment of the elevator lighting screen:
1. Test the beam effectiveness of the light curtain.
2. Test the detection distance of the light curtain.
3. Test the dislocation tolerance of the light screen, including horizontal tolerances, vertical tolerances and horizontal tolerances.
4. Test the comprehensive detection performance of the light curtain (including optical interference test).
5. Test the work reliability of the light curtain.
II. Main technical features
1. A high degree of automation: automatic test data collection, also can automatically analyze reliability test data of the shade number, screen response times, screen not response times and the screen not the distribution of response times in every section of screen;
2. High efficiency: the reliability test of two sets of lights can be carried out simultaneously, and the test efficiency is improved.
3. Safety and reliability: equipped with protective device, equipped with sound and light combination alarm function, which can guarantee the safety of staff;
4. Automatically save multi-batch test results and support report printing.
5. Support manual and automatic test mode.
6. The same structure design is adopted on both sides of the frame, and the supporting wall structure is designed to improve the overall stability of the frame.
7. Light screen horizontal movement, vertical mobile electric structure design, improve mobile stability and accuracy.
