Abstract
A remote locomotive control system includes a slave controller configured to receive data strings from remote transmitters. The slave controller is responsive to an acquire signal received from one of the remote transmitters for configuring the slave controller to control one or more control functions of the locomotive as a function of one or more data strings received exclusively from the one remote transmitter. However, the slave controller is configured so that any remote transmitter can control safety functions of the locomotive via the slave controller.

9. A remote locomotive control method comprising the steps of:
-
(a) providing a first transmitter, a second transmitter and a slave controller;
(b) receiving at the slave controller from the first transmitter a first data string that includes a first acquire bit in a first binary state and one or more control function bits related to one or more control functions of the locomotive;
(c) in response to step (b), causing the slave controller to control one or more control functions of the locomotive as a function of the one or more control function bits of the first data string;
(d) receiving at the slave controller from the first transmitter a second data string that includes the first acquire bit in its second binary state and the one or more control function bits; and
(e) in response to step (d), causing the slave controller to withhold controlling one or more control functions of the locomotive as a function of the one or more control function bits of the second data string. - View Dependent Claims (10, 11)

12. A remote locomotive control system comprising:
-
a first transmitter configured for radio transmitting a first data address and first acquire data;
a second transmitter configured for radio transmitting a second data address and second acquire data, the first and second transmitters also configured for radio transmitting control data regarding control functions of the locomotive and the safety data related to safety functions of the locomotive; and
a slave controller for radio receiving the data addresses, the acquire data, the control data and the safety data from the first and second transmitters, the slave controller responsive to;
the first acquire data received from the first transmitter for controlling control functions of the locomotive as a function of control data received from the first transmitter and for blocking control of control functions of the locomotive as a function of control data received from the second transmitter; and
safety data received from at least one of the first and second transmitters for controlling safety functions of the locomotive. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
