MEJORAS EN UN APARATO AUTOMATICO PARA COMPROBACION DE VEHICULOS

摘要

An automatic vehicle testing apparatus in which data representing conditions of units to be controlled are transmitted through optical transmission lines between a central station and terminal stations mounted on vehicles, which may be railroad cars. The central station can be placed in an automatic test mode. A test controller installed at a test location is operated to place the central station in the test mode. A response signal generating unit for operating each of the units in the vehicles and a monitoring unit for monitoring operations thereof are connected between each terminal station and the respective unit to be controlled. The data in the automatic test mode is transmitted through the optical transmission lines.
