摘要： A portable device permits testing of an EOT unit of a two-way end-of-train (EOT) radio telemetry system. During the test, the EOT unit may be mounted to and fully installed on the railcar on which it is to be used. The portable device includes a microprocessor unit, a display, and a transceiver that enables the invention to communicate with the EOT unit. The portable device also includes a mechanism for authorizing the portable device to communicate with the EOT unit. Used to control the overall operation of the portable device, the microprocessor unit operates the transceiver in cooperation with the aforementioned mechanism so as to authorize the portable device to communicate with the EOT unit according to an arming procedure. The microprocessor unit also operates the display on which the progress and completion of the arming procedure is indicated. When the portable device is authorized to operate with the EOT unit, the display is directed to indicate operational data that it receives from the EOT unit pertaining to the railcar to which the EOT unit is connected. The portable device further includes a mechanism for initiating an emergency reduction in pressure within the brake pipe of the railcar. When the emergency initiating mechanism is activated, the microprocessor unit commands the transceiver to transmit an emergency brake signal. It is by this emergency brake signal that the EOT unit is ordered to reduce the pressure within the brake pipe of the railcar at an emergency rate.

摘要： An electrical system architecture for a vehicle brake by wire system provides three electrical power sources: an electric generator, an electric power storage device such as a battery, and a third source which may be either an electric generator or storage device. An electric circuit has a common node and (1) connects the first electric generator to the common node through a first diode, (2) connects the first electric power storage device to the common node through a second diode, (3) connects the electric power source to the common node through one of the first and second diodes, and (4) connects the common node to the electric power inputs of control unit through circuit breaker devices. A sub-circuit within the electric circuit interconnects the first and second diodes, the common node and the first and second circuit breaker devices and isolates them within a zone protected from short circuits to points outside the zone. Voltages across the diodes are checked when the first diode should be reverse biased and again when the second diode should be reverse biased to detect circuit faults such as short or open circuits.

摘要： A knob arrangement for operating parking brakes intended for use in vehicles comprising brake units and an electrically operated tensioning device for applying or releasing braking force to the brake units. According to the invention, a device is arranged to sense the position of the knob and to send control signals to a first electric motor which is arranged to power the tensioning device for generating a braking force corresponding to the position of the knob. The knob is manually adjustable and, in a fully applied position, at maximum braking force, mechanically lockable. A control motor is arranged to automatically displace the knob to the fully applied and mechanically locked position dependent on second control signals applied to the motor. In its fully applied, locked position the knob is only releasable from the locked position by manual operation.

摘要： A rotational speed of an electric motor 12 is memorized at a memory unit 21 as a set rotational speed for allowing a minimum required volume of brake fluid to be discharged from the pumps in a state where the output hydraulic pressure of the master cylinder is highest, and an energizing duty ratio for the electric motor 12 which is designed so as to rotate the electric motor 12 at the set rotational speed is determined at a duty ratio determining unit 22 in response to an applied voltage detected at a voltage detecting unit 20. A motor control unit 23 controls the energizing of the electric motor 12 from a battery 18 in accordance with the energizing duty ratio determined at the duty ratio determining unit 22.

摘要： Method and apparatus for controlling braking on a train having ECP railcars using a conventional automatic brake valve. The locomotive and railcars are connected to brake pipe and a wireline, or use RF communications. A brake handle or other brake control valve interface is operated to cause a pressure change in an equalizing reservoir. The relay valve is isolated from the pressure change and connected to a reference pressure whereby brake pipe pressure is maintained. The pressure change is sensed and a signal generated representative thereof which is used to determine the level of braking commanded on the railcars. The apparatus includes an interface unit interposed between pertinent ports connecting the automatic brake valve, equalizing reservoir and brake pipe, and an equalizing reservoir pressure sensor to provide an output signal to an ECP controller for controlling braking on the railcars.

摘要： An electromechanical braking system utilizes redundancy features to provide safe and reliable braking. The braking system is configured to operate on power provided by multiple power sources. Different modes of braking are available based on whether a failure has occurred in one or more power sources. Additionally, system redundancy allows for failure in one or more primary components without total loss of braking capacity. Proportional braking is provided even in an emergency braking mode.

摘要： An apparatus and method for low power ECP brake emulation in a freight train having ECP equipped cars and one or more non-ECP equipped locomotives wherein power for the ECP equipment is provided by the 74 VDC locomotive battery. The apparatus includes an adapter for interfacing the locomotive MU cable and the ECP wire to supply sufficient power to operate the ECP equipment on each car indefinitely in a low power emulation mode. The method includes interfacing the locomotive MU cable to the ECP wire, implementing a low power emulation mode wherein pneumatic signals sent via the brake pipe are detected by pressure sensors and communicated to ECP control valves for changing the brake cylinder pressure accordingly. The method further includes minimizing power consumption by providing power only to the brake pipe sensors and minimal electronics to monitor pressure changes and thereafter activating other sensors and controls only as needed.
