Title:
CLEANING DEVICE FOR RAILROAD VEHICLE
Document Type and Number:
Japanese Patent JPS62168751
Kind Code:
A
Abstract:
PURPOSE:To certainly clean a variety of connected vehicles by installing a counter part which adds one part of the pulse signals supplied from the wheel detectors arranged on the upstream and downstream sides of a cleaner and subtracts the other parts and outputting the cleaning control signals from the both parts. CONSTITUTION:If the pass of the wheels 3a, 3b... of a vehicle 3 are detected by the first wheel detector 1, when the vehicles 3 and 4 are cleaned during the advance in the A direction, R-S.FF 8c is set through a 2-AND circuit 8b by the above-described detection signal, and the counted value of a counter part 8a is successively increased, and an H-signal is outputted from a preset terminal. Therefore, an L-signal is outputted from a 2-AND circuit 8f, and an H-signal is outputted from a 2-AND circuit 8g, and a cleaner 2 is driven. When the second wheel detector 9 detects the pass of the wheels 3a, 3b..., the counted value is successively reduced in the counter part 8a, and when the counted value becomes zero, the cleaner 2 is brought into stop after the lapse of a prescribed time through a one-host circuit 8i, etc.
