<p>PURPOSE:To enable to reliably and rapidly identify a vehicle in which a malfunction occurs only by a pair of signal lines by using a time division multiplexing transmission system and transmitting notice signals from the vehicle in a series transmission. CONSTITUTION:Notifying units B1, B2,..., B8 are respectively provided in vehicles A1, A2, ..., A8, and receivers C1, C2 are provided in crewman cabs of the vehicle A1, A8 of both ends. Sets of two signal lines (a) of signal and ground sides and a buzzer circuit line (c) are provided between the vehicles A1, A2,..., A8. The units B and the receivers C are connected to the signal lines (a) and the circuit lines (c), and power sources of the vehicles A1, A2, ..., A8 are supplied to the units and the receivers. The notifying signals between the units B1, B2,...,B8 and the receivers C1, C2 are transmitted in series by a time division multiplexing system.</p> |
