|Applicants:||CRRC QISHUYAN CO., LTD
|Title:||WIRELESS LOCOMOTIVE DOUBLE-HEADING TEST DEVICE|
A wireless locomotive double-heading test device comprises a double-heading terminal control box and a remote control, wherein the double-heading terminal control box and the remote control are connected to each other via two wireless modules. The double-heading terminal control box is connected, using a standard 27-pin double-heading connector, to a locomotive. The double-heading terminal control box is directly attached to a tail part of the standard 27-pin double-heading connector. The double-heading terminal control box comprises 27 channel selection switches, 24 digital data isolating and sampling channel, 1 resistive brake simulation data sampling and driving channel, a first single-chip microcontroller, an IO expansion module 1, and an IO expansion module 2. The IO expansion module 1 and the IO expansion module 2 are connected to and arranged on the first single-chip microcontroller. The device is universally compatible to various types of locomotives, requires a small number of operators during a test, has short preparation time and little limitation in testing location, and is simple to coordinate a test.
