摘要： PROBLEM TO BE SOLVED: To provide a means which secures high reliability on the trouble of a network by securing the real time nature of control information even if media information is transmitted at the same time, in the mobile network of a rolling stock. SOLUTION: An NCP11 in the first system is connected to a trunk transmission path 1N in the first system via a switching hub 12 in the first system. It is connected to an equipment controller 15 in the first system, an equipment controller 25 in the second system, and a switching hub 22 in the second system via a control information transmitter 13 in the first system. It is connected to information equipment 16 in the first system via a media information transmitter 14 in the first system. The second system is the same. A switching hub 2 transmits control information preferentially when it receives the control information and the media information. A control information transmitter 3 receives data from two trunk transmission paths N, and transmits the data from the same system as a local station to an equipment controller 5. When the transmission is interrupted in one trunk transmission path N by trouble, it relays the data that the other trunk transmission path N has received to the trunk transmission path N where the transmission is interrupted.

摘要： PROBLEM TO BE SOLVED: To provide a high reliability information transmission system which is capable of continuing the transmission even in the event of multiple failures.
SOLUTION: Two trunk transmission lines 21, 22 are provided for connecting transmission terminals 111-124 to both lines. Each transmission terminal 111-124 transmits also received data from other transmission terminals to both trunk transmission lines 21, 22 when transmitting data of own transmission terminal. Thus, each of transmission terminals 111-124 repeatedly transmits data to enable the data transmission even in the event of multiple troubles such as troubles at two points with a marked X.

摘要： PROBLEM TO BE SOLVED: To provide a loop network controller capable of surely detecting an intermittent trouble on a transmission line comparatively simply. SOLUTION: In a first decision means for an intermittent-trouble detecting means, the intermittent trouble is decided at a step S4 from an incompleted loop-back reconfiguration within a fixed time by a timer A at a step S1. In a second decision means, the number of the loop-back reconfiguration is integrated on a counter table at a step S2, whether or not the loop-back reconfiguration in the number exceeding a fixed threshold value is conducted within the time of a timer B having a certain time constant is decided, and the intermittent trouble is decided at the step S4 when the number exceeds the threshold value as the result of the decision. In a third decision means, whether or not the integrated error value of the transmission line exceeds the fixed threshold value within a fixed time by a timer C is decided at a step S3, and the intermittent trouble is decided at the step S4 when an excess over the fixed threshold value of the integrated error value is detected.

摘要： PURPOSE:To avoid reception omission of a transmission data by applying transmission control by giving/receiving of a conventional token frame after a transmission enable time of each station is circulated. CONSTITUTION:Station 101-104 are connected to a transmission line 2. When a count of a counter 9 of any station reaches a prescribed value and each station receives a data frame or a token frame multiplied with the prescribed value, the frames are sequentially allocated so that they are not overlapped among stations and only one transmission from a station is implemented by a transmission enable time when the time length reaches one period of a timer 8. Thus, when the assigned transmission enable time is circulated among the stations, the control takes over the normal transmission control by using a token. Thus, reception omission of data to be received is prevented.

摘要： PURPOSE:To apply optimum load control even when a node station is subscribed to a system newly by allowing each node station to reserve a function inquiring about the waiting number for data processing to other node station when the titled controller is incorporated in a multiple address communication system. CONSTITUTION:A counter 17 is controlled directly by a microprocessor 8, incremented by 1 when a frame sent from other node station or its own node station is received, and decremented by 1 at each prescribed period by a timer built in the microprocessor 8. A node station subscribed newly detects a POL to recognize an idle line, outputs a PSV signal to occupy the line. Then a pattern representing a field inquiring about the waiting number for data processing waiting is set to a control frame C and a frame setting a pattern representing the multiple address communication to a destination address DA is sent to the line. Then the POL signal is sent to release the line thereby awaiting the reply from the other station.

摘要： PURPOSE:To speed up abnormal operation analysis of a computer system and make it possible to execute connection test to a terminal easily by detecting development with time of event of an input/output controlling device connected to a host and a terminal in synchronism with a timer in the host. CONSTITUTION:A timer 2b in an input/output controlling device 2 is reset to 0 by a trace starting and setting means at the time of event trace starting, and the time of a host timer 1c at the point of time is added later to trace data. Accordingly, the input/output controlling device timer 2b is synchronized with the host timer 1c at the time of trace starting, and the time of occurrence of event in the input/output controlling device 2 can be measured almost exactly by timing of the host timer 1c, and extra burden on the processor 2a for it is not caused. Further, in case of receiving a time data message from a terminal 3, connection test can be executed easily as timing of the terminal side timer is synchronized by a time error of the time of receiving.

摘要： PURPOSE:To compare a supervising signal with the number of the steps of the allowable by-pass stored beforehand, to once recognize the address of plural stations and to execute the high speed of a trouble detecting place at a double ring network by sending the simultaneous instruction of a trouble searching to respective transfer stations with a master station and outputting a supervising signal including a self- address with respective transfer stations. CONSTITUTION:Plural transmitting devices 1-N and terminal equipment 1a-Nc connected to the devices 1-N are connected to ring transmission lines Oa and Ob, a double ring transmission line is formed, connected through the devices 1-N to respective arbitrary equipment 1a-Nc, connected mutually and a ring network is constituted. By a by-pass means 10 of the transmitting device N, the transmission lines Oa and Ob are by-passed from the devices 1-N and the relation of the devices 1-N and the double transmission line is switched by a channel switching means 20. By a constitution control means 40, the detection of the trouble position is executed, the means 20 is controlled and the information transmission of the means 40 between the devices 1-N is executed by an information transmitting means 30. When a master station detects the trouble, the means 40 of respective devices 1-N instructs the sending of a supervising signal.
