摘要： A control system including apparatus for the transmission of information for the control of vehicles travelling in one direction on a guideway. The guideway is broken down into a plurality of groups of uniquely identified sequential blocks. Each block has at least one vehicle detector for detecting the presence of a vehicle and having an operated condition responsive to vehicle detection. Each block further includes a transmitter for providing, to a vehicle within the block, information concerning the block it is in as well as information regarding the identity of the next downstream occupied or unavailable block. To this end, each block has associated with it a word generator for producing a signal identifying the block; the word generator is coupled to the block transmitter, which transmitter is only enabled when the vehicle detector is in its operated condition. A communication channel extends in a direction opposite to the direction of travel on the guideway, and each block includes a coupler for coupling the portion of the communication channel co-extensive with the block to the adjacent upstream block. The coupler is responsive to the condition of the vehicle detector for maintaining a connection between the communication channel in the block with the communication channel of the next upstream block, when the vehicle detector is not operated. When the vehicle detector is operated, the coupler connects the output of the word generator to the next upstream block. The transmitter of each block receives another input from the communication channel. In this fashion, a vehicle in any block receives a signal identifying the next downstream occupied block as well as a signal identifying the block it is in.

摘要： A highway crossing warning system includes a motion detector transmitter and receiver respectively coupled to the track rails adjacent the highway crossing for detecting motion of an approaching train. Wrap-around approach sections initiate operation of the highway crossing warning, but once motion is detected, the motion detector can serve to inhibit the highway crossing warning, after a predetermined delay, if motion indication ceases. To increase the effectiveness of the motion detection, the motion detector transmitter impresses a modulated carrier onto the track rails, wherein the modulation is phase locked to the carrier. The receiver, tuned to the carrier frequency, detects the modulation, and then determines from the level of demodulated signal whether or not approaching motion is detected. The transmitter employs solid state circuits switched between saturated and off conditions to prevent circuit component failures from masking approach motion. The ring sustain time period is arranged to provide a minimum constant warning time regardless of variations in train movement, so long as train velocity is maintained above a predetermined threshold within a predetermined distance from the crossing.

摘要： Broken rail detection in a block of track without the need or expense of conventional signalling uses a chain of transmitters and receivers connected to the rails and defining sections of the block between the ends of the block. Either cyclically at a predetermined code rate or upon command of an external unit; an alternating current (AC) signal is launched from one end of the block and is repeated at different frequencies in each of the sections. When received at the end of the block, an indication of the absence of a broken rail condition is given either (a) by way of pole line or radio communication to a central control or dispatcher point and thence back to the trains, or (b) signals at the ends of the block are flashed at the code rate. The detected signal at the code rate may be used to modulate a direct current which is transmitted along the rails in the block to a signal at the opposite end of the block which also flashes at the code rate to indicate a safe condition. When it is desired to allow more than one train into a block, a signal may be launched after the first train has entered the block. A second train may then enter the block at restricted speed. When the first train exits the block, the previously launched signal arrives at the receiving end providing an indication that the rail is intact in front of the second train.

摘要： Apparatus for insuring a vehicle operator's attentiveness at potentially dangerous locations along a path of travel. A signalling device is provided in advance of a potentially dangerous location, in the direction of travel of the vehicle. A vehicle carried signal responsive device responds to the signalling device when within the effective zone of the signalling device. The vehicle includes warning apparatus, for example, an alarm and a buzzer. The vehicle also includes an operator actuatable push button and a speed sensing apparatus. A control device responds to the push button and to the vehicle carried signal responsive device to operate either the buzzer or the alarm. If the operator evidences his alertness to the potentially dangerous location by actuating the push button prior to reaching the signalling device (within some constraint), the control apparatus merely sounds the buzzer when the signalling device is detected and resets itself. On the other hand, if the operator fails to actuate the push button in advance of detection of the signalling device, or, if his actuation is too far in advance of detection, then the alarm is energized and will remain energized until the vehicle is brought to a stop, or a low speed, at which point, push button actuation can cancel the alarm.

摘要： The control system operates vehicles over a right-of-way divided into a plurality of zones and selects the direction of traffic along the right-of-way. The presence of a vehicle is sensed when it enters the zone from either direction and the occupancy of the zone is registered. The occupancy registration is indicated by a magnetically actuated switch to operatively control restrictive aspects in accordance with selected number of zones behind the leading vehicle relative to the selected direction of traffic.
