Document Type and Number:
WIPO Patent Application WO/2022/247192
Kind Code:
A1
Abstract:
A rail vehicle door system test controller, comprising a door control signal generator (100), which is used for generating and outputting a door control signal on the basis of a preset frequency; a first solid-state relay (K1), which is used for the door control signal which is output by the door control signal generator; a second solid-state relay (K2), wherein an input end thereof is connected to an output end of the first solid-state relay (K1), and an output end thereof is connected to a door control signal input end of each door control system; a first delay relay (D1), wherein an input end thereof is connected to the output end of the first solid-state relay (K1); a third solid-state relay (K3), wherein an input end thereof is connected to an output end of the first delay relay (D1), and an output end thereof is connected to the door control signal input end of each door control system; and a counter (200), wherein an output end thereof is connected to the output end of the first solid-state relay (K1), and is used for counting the number of times that the first solid-state relay (K1) outputs a door control signal. Therefore, the test efficiency is improved, and the reliability of a test result is ensured.
