The train has a train wide communication network which includes a vehicle bus in each car of the train communicating with the power supplies and subsystems on the car, a train bus extending through the entire train, and communication nodes in each car interconnecting the train bus with each one of the vehicle buses. One of the communication nodes in one of the cars constitutes a master node and the other communication nodes in the other cars constitutes slave nodes, each slave node communicating status information about power supplies and subsystems on its vehicle bus to the master node and communicating control information to the power supplies and subsystems on its vehicle bus. The method includes using the communications network to periodically determine the number of functional power supplies connected in parallel, determining from the number of functional power supplies available for supplying power at any given time a variable corresponding to the total power available for power consuming subsystems on the train and selectively reducing subsystems on the train by way of the communications network in accordance with the variable determined by the determining step.
What is claimed is: 1. A method for controlling power consumed by a plurality of subsystems on a multi-car train having a plurality of power supplies connected in parallel for supplying power to the subsystems and a train wide communication network including a vehicle bus in each car of the train communicating with the power supplies and subsystems on the car, a train bus extending through the entire train, and communication nodes in each car interconnecting the train bus with each one of the vehicle buses, with one of the communication nodes in one of the cars constituting a master node and the other communication nodes in the other cars constituting slave nodes, each slave node communicating status information about power supplies and subsystems on its vehicle bus to the master node and communicating control information to the power supplies and subsystems on its vehicle bus, said method comprising:using the communications network to periodically ascertain how many of the power supplies connected in parallel are operating; determining, based on how many power supplies are operating and therefore available for supplying power at any given time, a first variable correpsonding to total power available for power consuming sybsystems on the train; and selectively reducing power consumption of subsystems on the train by way of the communications network in accordance with the first variable determined by said step of determining. 2. The method according to claim 1, wherein said step of selectively reducing power consumption includes:making a selection at the master node of the subsystems on the train to be de-energized in dependence on the first variable of said step of determining, and sending messages from the master node to the slave nodes for de-energizing the selected subsystems in respective ones of the cars. 3. The method according to claim 1, wherein said step of selectively reducing power consumption includes:sending the first variable determined by said step of determining to each one of the slave nodes, and causing each one of the slave nodes select subsystems on a respective one of the cars to be de-energized in dependence on the first variable. 4. The method according to claim 1, and further comprising the steps of:displaying the first variable determined by said step of determining on an operator's display console, alerting the operator that the train is in a reduced power consumption mode, receiving as input from the operator selections of subsystems on respective ones of the cars to have reduced power consumption, and transmitting messages over the communications network by way of the master node to the slave nodes for de-energizing the selected subsystems based on the selections input by the operator. 5. The method according to claim 1, wherein said step of determining further includes determining a second variable representing one minus the first variable to indicate a proportion of total load that must be reduced.
SUMMARY OF THE INVENTION An object of the invention is therefore to provide a method and apparatus to control power consumed by a passenger train by shutting off certain equipment whenever power supplies on the train are being overloaded.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic representation of a train and its associated trainline monitor (TLM) system in which the present invention has particular usefulness.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIG. 1, shown is a Trainline Monitor (TLM) System 120 in which the invention finds particular use. FIG. 1 shows a representative train 112 with a head car 114, a tail car 116, and middle cars 118. Only two middle cars 118 are shown, however a typical commuter train may have from one to ten middle cars 118 having essentially the same equipment on board.
