    摘要： In a communication network system with a plurality of nodes connected to a common transmission line, each master candidate node includes an idle time measurement device for measuring an idle time of the transmission line. Once each master candidate node acquires the master privilege and becomes a master node, the master node retains a master privilege until the idle time of the transmission line exceeds a longest of the privilege acquisition idle time widths of the master candidate nodes, the root node transmits a start frame indicating start of a next communicant cycle and the idle time measurement device is cleared upon receipt of the start frame.

    摘要： A driver circuit for a digital signal transmitting bus includes a main switch. The main switch is connected to the bus, is controllable by the digital signal to be transmitted, and has one on-switching state in which it has maximum electrical conductivity, one off-switching state in which it has minimum electrical conductivity and at least one intermediate switching state with an electrical conductivity between the minimum and maximum conductivity. The digital signal has a first logic state and a second logic state, the first logic state controls the main switch to be in the on-switching state and the second logic state controls the main switch to be in the off-switching state. The main switch is in the intermediate switching state during switching from the on-switching state to the off-switching state and/or vice versa.

    摘要： A control section of a distribution apparatus decides whether data included in message has been stored by own DB or not, when distributing the message to an onboard apparatus based on transmitted information registered by second transmitted information table. From own DB, the control section of the distribution apparatus reads out data having been stored by the DB. For data that has not been stored by own DB, the control section of the distribution apparatus identifies another distribution apparatus having stored this data, and obtains this data from the identified another distribution apparatus. The control section of the distribution apparatus creates message including the data read out from own DB and the obtained data, and transmits the created message to an onboard apparatus which is a destination.

    摘要： At least one node on a network acquires boundary violation information and frame state information concerning a reception slot and adjacent slots. Based on the boundary violation information and frame state information concerning the slots, the node verifies an error factor in the reception slot. Based on verification of the error factor, the node determines that data of a frame received in the reception slot can be used. When determining that the data of the received frame can be used, the node uses the received frame for control.

    摘要： A special node is used in a distributed time-triggered cluster. The special node comprises protocol functionality to establish a time base to use in communicating with a plurality of end nodes and to source timing-related frames to the plurality of end nodes in accordance with the distributed time-triggered communication protocol. The protocol functionality establishes the time base without regard to any timing-related frame sourced from any of the plurality of end nodes. In one embodiment, the protocol functionality of the special node is implemented in a low complexity manner. In one embodiment, the cluster comprises a star topology and the special node performs at least one of semantic filtering and rate enforcement. In another embodiment, the cluster comprises a bus or peer-to-peer topology and each end node is coupled to the communication channel using a low-complexity special local bus guardian.

    摘要： A multi-node communications system is provided with communications protocol using both static (11, 12, 13, 18) (pre-determined) and dynamic (51, 52, 53 . . . ) (run-time determined) consecutive communication slots is used. The system has a number of distributed communication nodes, each node being arranged for communicating frames of data with the other nodes during both the static (11, 12, 13 . . . ) and the dynamic (51, 52, 53 . . . ) communication slots. Each node includes a synchronized time base 5 made up of consecutive timeslots (11, 12, 13 . . . , 51, 52, 53 . . . ). The timebase 5 has substantially the same error tolerance in each node. For static communication (10), a predetermined number of timeslots (20) are utilized for each static communication slot. For dynamic communication a dynamically allocated number of timeslots (60) are utilized for each dynamic communication slot. In this way both static and dynamic media arbitration is provided within a periodically recurring communication pattern. Communication jitter is well defined and dealt with, and large oscillator drifts are compensated for.

    摘要： A system and method for providing fault detection capability is provided which comprises a first node (2). The first node (2) comprises a first processing subsystem (5) generating data (14) to be transmitted. The first node (2) has a fault supervisor unit (13) adapted to gather and process fault indications arising in the first node (2). The first processing subsystem (5) and the fault supervisor unit are both integrated in the first node (2). The first node (2) is structured such that, when no fault indications are detected by the fault supervisor unit (13), the fault supervisor unit (13) provides a first key (15) as a validity key, and, when at least one fault indication is detected by the fault supervisor unit (13), the fault supervisor unit (13) provides a second key (16) as the validity key, and the data (14) to be transmitted are encrypted by overlaying the respective validity key (15; 16) on the data.

    摘要： A central node for a data bus system includes a bus monitor unit with receiver means for registering signals on the data bus, and evaluation means which detect incorrect communication on the data bus and at least temporarily block communication by the user that causes the incorrect communication or compensate the incorrect communication of a user which is triggered by the interference influences. The bus monitor unit includes timing means which are triggered according to time patterns for the transmission of each user of the data bus, in order to detect an incorrect communication of a user if the latter transmits outside the time provided for it. The bus monitor unit is integrated into the central bus node and a plurality of bus branches of different users are combined at the central node so that the bus monitor unit can check a plurality of users for incorrect communication. In order to increase reliability, in addition to the bus monitor unit, a diagnostic unit is integrated into the central node. The latter monitors the bus monitor unit in terms of regular retriggering in response to the time patterns, so that the bus monitor unit can be deactivated in the absence of retriggering.
