摘要： The present invention provides a system for automatically controlling the distance between vehicles following each other on the same drive track which includes in each vehicle a drive device, brake device, distance sensing device, vehicle speed measuring device, and control device. Paralleling the drive track are a neutral rail and a control rail. The drive device drives the vehicle. The brake device brakes the vehicle. The distance sensing device generates a distance variable. The vehicle speed measuring device measures a speed of the vehicle, and generates speed signals based thereon. The control device controls the drive device to drive the vehicle at a speed based on a speed control variable. The control device generates the speed control variable based on the distance variable. The speed control variable is less than the distance variable. The control device also controls the brake device to brake the vehicle when a speed signal is greater than a maximum permissible speed; the maximum permissible speed being dependent on the distance variable.

摘要： In an electrical propulsion system on board a moving traction vehicle (such as a rapid transit rail car) having current collectors in contact with an energized third rail, controllable switch means is used to connect the system to the current collectors. From time to time the current collectors traverse gaps between adjacent sections of the third rail, in which event regenerative braking operation of the system will be prevented unless the next third rail section is energized by a wayside source of voltage. The switch means comprises the parallel combination of a diode that conducts current when the system is operating in a motoring mode and a reversely-poled thyristor that conducts regenerative braking current once a firing signal is applied thereto. To detect the energized status of the third rail, an electrical filter network is excited by the third rail voltage and derives an output value representative of the amplitude of an a-c ripple component of such voltage having a fundamental frequency that characterizes the wayside voltage source, and after each third rail gap is traversed a firing signal is applied to the thyristor as soon as this value exceeds a predetermined minimum level.

摘要： A system and method for movement of self-propelled vehicles in-line along a rail under external control is intended to ensure safe spacing between vehicles to avoid collisions. Each vehicle is driven by its own variable speed motor. The speed of the vehicles is controlled by a stationary cam extending beside the rail. The edge of the cam rises and falls in a predetermined manner and is sensed by a cam follower on each vehicle. The cam follower is coupled to a transducer which produces a control signal for varying the vehicle speed in response to the rise or fall of the cam edge. Each vehicle pulls along a tail which extends behind the vehicle and is guided for motion alongside the edge of the cam. If a rear vehicle approaches a forward vehicle sufficiently closely for the cam follower of the rear vehicle to be raised from the cam edge by contact with the tail of the forward vehicle, the transducer of the rear vehicle is thereby caused to signal its drive motor to move the rear vehicle at a speed no faster than the forward vehicle, to avoid collision with it.
摘要翻译： 用于在外部控制下沿着轨道行进的自行式车辆的系统和方法旨在确保车辆之间的安全间隔以避免碰撞。 每辆车都由自己的变速马达驱动。 车辆的速度由在轨道旁边延伸的固定凸轮控制。 凸轮的边缘以预定的方式上升和下降，并且由每个车辆上的凸轮从动件感测到。 凸轮从动件耦合到换能器，该换能器响应于凸轮边缘的上升或下降而产生用于改变车辆速度的控制信号。 每个车辆沿着延伸到车辆后方的尾部拉动并被引导以沿着凸轮的边缘运动。 如果后方车辆通过与前方车辆的尾部接触而使后车辆的凸轮从动件从凸轮边缘升高而靠近前方车辆，则后车辆的换能器由此被引导到其驱动马达 以不比前方车辆更快的速度移动后方车辆，以避免与其碰撞。

摘要： A system for controlling the movement of carriages in a conveyor system is disclosed in which individually powered carriages are controlled so as to stop a carriage at a designated position on the conveyor rail. Electrical contact wires extend along the conveyor rail and are electrically connected to controller units on each of the carriages by electrical contacts sliding along the electrical contact wires. Certain ones of the electrical contact wires have electrical discontinuities which define boundaries of first and second zones. The electrical discontinuities form a normally open electrical circuit with the controller units of each of the carriages, thereby keeping such controller units in the inoperative or "off" position. In this position of the controller unit, the power unit of each of the individual carriages drives the carriage along the conveyor rail. When the electrical circuit of the electrical contact wires is completed in a first zone, such as by the presence of a stopped carriage or other obstruction, the controller unit of a carriage entering the adjacent second zone will be actuated by this completed electrical circuit and will stop the carriage before it encounters the stopped carriage or other obstruction.

摘要： The invention is a conveyor control system having self-propelled vehicles having wheels, each driven by a motor (14) to move along rails. The system includes power rails (18) for supplying power to the vehicle (12) and at least one command rail (20, 21) which transmits a constant command signal indicative of requested speed. The command rail (20) is comprised of isolated sections of rail for carrying different command signals along each isolated section to enable the vehicle (12) to travel at different speeds dependent on which section of rail the vehicle is within. The command signal may be in the form of an analog signal on one rail (20) or a digital signal on two rails (20, 21). Each vehicle (12) includes a control circuit (22) which interprets the command signal to drive the vehicle (12) at the requested speed. An override circuit (28, FIG. 2b, FIGS. 3 and 4) senses external activity for proper control of the circuit. The override circuit can slow down the vehicle ( 12) or stop the vehicle (12) when within a predetermined distance of another vehicle, or stop the vehicle (12) in response to a fault in the control circuit (22).

摘要： Control apparatus carried on each train traveling on a nonconducting right-of-way is coupled across a signal transmission channel comprising one propulsion conductor and a sectionalized signal conductor. A wayside signal source transmits a direct current signal, having distinctive predetermined voltage level and polarity characteristics, through each channel section to control train speed and door functions. Each signal conductor section also constitutes one side of a train detection circuit including the signal source and a detector relay. The other side of all detection circuits is established by relay and source connections to a common bus, so that each relay is normally energized. The detector relay shunt circuit is established through the train-carried apparatus to the propulsion conductor and thence its connection to the common bus. Each detector relay thus releases when a train occupies the associated section. Each train detection circuit between stations also includes a front contact of the next advance section detector relay so that station-to-station block occupancy registry is maintained until the train departs from the next station, thus assuring stationto-station train separation.

摘要： The path of the vehicle is divided into successive intervals of space. An adjustable, periodic, pulsed reference signal is provided for each interval, and its frequency is adjusted so that the product of this frequency by the length of the corresponding interval is proportional to the speed desired for the vehicle on this interval. The number of reference pulses received by the vehicle during its travel along each interval is counted and compared with a determined fixed base number to compare the real speed of the vehicle with the desired speed.
