摘要:
The invention refers to one of a number of nodes of a communication system. The nodes are connected to a communication media for transmitting data among the nodes. Said one node comprises a communication controller, across which the node is connected to the communication media, and a bus guardian for controlling access of the communication controller to the communication media. In order to provide a cheap but nevertheless reliable way for monitoring the synchronized clock signal of a node of a communication system and in particular for detecting deviations of the synchronized clock signal it is suggested that a synchronized clock signal from the communication controller is made available to the bus guardian, and that the bus guardian comprises means for monitoring the synchronized clock signal using a bus guardian internal clock signal, which is generated by means of an electronic circuit and which is less accurate than the synchronized clock signal to be monitored.
摘要:
The present invention provides an improved clock synchronization algorithm for a distributed system intended for real time applications by performing at the same time an off-set correction and a clock read correction at each node of the distributed system. Expensive oscillators can be avoided and synchronization can be established faster and with higher precision.
摘要:
A method for the exchange of data in messages between at least two users which are connected by a bus system, the messages containing the data being transmitted by the users via the bus system, and each user containing a predefinable and/or ascertainable timing mark; a first user, in a function as timer, controls the messages as a function of time in such a way that it repeatedly transmits a reference message, which contains time information of the first user, via the bus at a specifiable time interval, and if the timing mark of the second user is reached without a reference message of the first user reaching the second user, the at least second user takes over the function of timer by transmitting its own reference message with its own time information via the bus system.

摘要:
A method and a communication system for exchanging data between at least two users interconnected over a bus system are described. The data is contained in messages which are transmitted by the users over the bus system. To improve data exchange among users so that in the normal case, there is a high probability that it will be possible to transmit messages with a low latency, while on the other hand, in the worst case, a finite maximum latency can be guaranteed, the data be transmitted in an event-oriented method over the bus system as long as a preselectable latency period elapsing between a transmission request by a user and the actual transmission operation of the user can be guaranteed for each message to be transmitted as a function of the utilization of capacity of the bus system, and otherwise the data is transmitted over the bus system by a deterministic method.
