Abstract: A service managing system includes a plurality of business computers, and a service managing apparatus communicably connected to the business computers. A processing unit in the service managing apparatus references influence information, configuration information, and operating process information stored in a storage unit, when the processing unit instructs a start-up of a process to any of the business computers. The processing unit then identifies any other process(es) and its corresponding service(s) to be influenced by the start-up instruction.

Abstract: An obstacle detection system includes a leaky transmission path, a leaky receiving path opposite to the leaky transmission path, a spread spectrum signal generator connected to an end of the leaky transmission path and generating a spread spectrum signal for radiation from the leaky transmission path to detect an obstacle. A correlator is connected to an end of the leaky receiving path to calculate a level of correlation between a reference spread spectrum signal and a spread spectrum signal received by the leaky receiving path. A detector detects an obstacle in accordance with a change in the level of correlation calculated by the correlator.

Abstract: A train traffic control system which automatically prepares a shuttle service diagram based on a partial simulation of each train, at each station, etc., executed only by setting such initial data of the shuttle service as current states of trains in operation and possibility of service extension to other line, that is, other company line, a branch line or the like, when the shuttle service is required in a limited train section due to railroad accident or the like during the traffic control by a normal diagram, and controls the train route according to the shuttle service diagram.

Abstract: An information transmission system is provided for railway vehicles wherein optical transmission between cars of trains is preformed. A predetermined signal corresponding to information to be sent from a transmitting portion is added in succession to the information. The information is then transmitted and a receiving portion receives the information and the additional signal. The receiving portion compares the information and the additional signal to detect a transmission error. When an error rate has exceeded a predetermined value, a predetermined display signal is provided. Also, the transmitting and receiving portions are coupled to an alternative data transmission path.

Abstract: Train monitoring equipment for a train formed by coupling a plurality of sets of cars of fixed formations, comprising monitoring stations mounted in the respective cars of the train and connected serially by transmission lines. Presetting switches are provided in the respective monitoring stations for presetting the formation numbers of the sets of cars in which the respective monitoring stations are located. One of the monitoring stations which serves as the control station transmits its formation number to the other monitoring stations which then register their station numbers on the basis of conformity or non-conformity of the preset formation numbers with the received formation numbers.

Abstract: The inspecting apparatus for measuring sensors mounted on a train of this invention comprises a transmission center having a memory and data output unit being installed, for example, in the first car of a train, and individual transmission terminals to fetch the data from measuring sensors being installed in all cars including the first one. The measured data from each measuring sensor is fetched from each transmission terminal into the transmission center, stored into the memory, and processed by comparing with the initial value and the like, and the result of such processing is provided into the data output unit. Accordingly, since inspection in the same conditions as real operation is possible, without dismounting the measuring sensors from the train, the monitoring of a train can be continuously carried out.

Abstract: A railway car order selecting system in which data representing the positional order of the various cars of a train and other data is accurately communicated to a central station regardless of the particular arrangement of the cars. A selecting relay applies an input signal to one of plural data transmitting devices, one being located on each car, to select a front car of the train. Extension lines connected into a single line connect the data transmitting devices to one another and are used for selecting the car order. Logic circuits are provided for the extension lines to supply, in response to an output signal from the respective data transmitting devices, a supply voltage to the following data transmitting device. Selection of the front car in this manner results in starting the data transmitting devices on the following cars successively and registering the positional order of the following cars in the data transmitting device at the front car.

Abstract: In a car data transmission device installed in cars to transmits data through the cars by means of optical fibers, optical fiber lines for data transmission are provided to be looped in duplex through a row of cars; each of cars is provided with optical fiber cables, each receiving therein the duply looped optical fiber lines as one unit whose data transmitting direction different each other; and jointing optical fiber cables are placed between the adjacent cars to pass the duply looped optical fiber lines as one unit received in the optical fiber cable placed in each of the adjacent cars whereby interruption of the data transmission lines is prevented even though a trouble of transmission such as breaking of one of the jointing optical cables occurs.

Abstract: A light transmission system for a train which includes sub-train compositions. Ths subtrain compositions each have end vehicles, one of which forms a head and the other of which forms a tail with respect to the moving direction of the train. The end vehicles each include a central station responsive to a first command signal from the front platform of the train to perform a central function for producing a second command signal and responsive to the second command signal to perform a terminal function which passes therethrough any input signal when an adjacent central station is found to be connected thereto and which returns any input signal when no adjacent central station is found to be connected thereto, thereby forming a complete signal transmission path in the train.

Abstract: An automatic vehicle testing apparatus in which data representing conditions of units to be controlled are transmitted through optical transmission lines between a central station and terminal stations mounted on vehicles, which may be railroad cars. The central station can be placed in an automatic test mode. A test controller installed at a test location is operated to place the central station in the test mode. A response signal generating unit for operating each of the units in the vehicles and a monitoring unit for monitoring operations thereof are connected between each terminal station and the respective unit to be controlled. The data in the automatic test mode is transmitted through the optical transmission lines.
