摘要： A control network communication arrangement includes a second protocol embedded into a first protocol in a way that modules supporting the second protocol may be aware of and utilize the first protocol whereas modules supporting only the first protocol may not be aware of the second protocol. Operation of modules using the second protocol does not disturb operation of the modules not configured to use or understand the second protocol. By one approach, the messages sent using the second protocol will be seen as messages sent using the first protocol but not having a message necessary to understand or as needing a particular response. In another approach, modules using the second protocol can be configured to send message during transmission of first protocol messages by other modules, the second protocol messages being triggered off of expected aspects of the message sent under the first protocol.
摘要翻译：控制网络通信装置包括以支持第二协议的模块可以知道并利用第一协议的方式嵌入到第一协议中的第二协议，而仅支持第一协议的模块可能不知道第二协议。使用第二协议的模块的操作不会影响未配置为使用或理解第二协议的模块的操作。通过一种方法，使用第二协议发送的消息将被视为使用第一协议发送的消息，但是不具有理解或需要特定响应所需的消息。在另一种方法中，使用第二协议的模块可以被配置为在由其他模块发送第一协议消息期间发送消息，所述第二协议消息是从根据第一协议发送的消息的预期方面触发的。

摘要： There is a need for increasing the availability of data and/or control commands in a distributed control system for one or more machines, vehicles and/or processes. The control system comprises or is controlled by a transmitting node or transmitter unit and has two or more receiving nodes. The transmitting nodes and receiving nodes are connected to each other via wireless radio links. The receiving nodes are located at a distance from each other and are connected to a few-wire digital link in a wired system for forwarding of the said data and/or control commands to the executing devices. The control node transmits the said data and/or the control commands in different directions towards the receiving nodes which are arranged at a distance from each other. Receiving nodes with reception that is essentially not subject to interference are arranged to be able to connect to the few-wire link in parallel and simultaneously with a receiver unit or units which have links that are connected to the few-wire link. In another case, only those receiver unit or units are connected that have reception links that are not subject to interference, while the receiver unit of units with links that are subject to interference do not participate in the transmission of the message on the few-wire link.

The system comprises at least one of a plurality of modules that further comprise at least one actual clock. The at least one module further comprises a scheduler coupled to the at least one clock, wherein the scheduler is configured to receive a virtual schedule comprising a time slot for sending a message to the communication bus. The scheduler is further configured to determine an actual time for sending a message in relation to the virtual schedule and according to time kept in the at least one actual clock. The module is configured to send a message according to the actual time, wherein the module starts transmission of the message according to the actual time. By sending the module at the actual time, the message begins within an adjacent time slot on the communication bus.

摘要： An arrangement and a device comprises a mobile data and communication network within a predetermined geographical area. The device operates with first and second functions that can consist of, for example, company and/or customers functions and communication and/or slave functions respectively. Two or more units in the first function are synchronized with each other as regards time and frequency in order to act, from the point of view of connection and disconnection functions, as a common first unit for second units that carry out the second function. Time consuming handshaking procedures are then avoided for the second units when these one's are moving and shifting between part areas of said predetermined area and the total system will operate rapidly in this respect.

摘要： In a CAN system, an arrangement is incorporated for making possible more efficient utilization of available band-width on the system's bus connection between, from and/or to modules incorporated in the system and/or reduction of accuracy requirements for clock functions utilized in the system. The system operates with communication on the bus connection that is in accordance with rules set up in the system and constitutes a combination of event-driven and time-controlled communication functions. The said functions are, together with a rule change in the time-controlled communication function, arranged to achieve the said making more efficient and/or reduction. The rule change is arranged to bring about deliberate collisions between messages appearing on the bus connection. In this way, the bandwidth utilization, the clock function and the system's general construction and function can be simplified according to the requirements imposed.

摘要： A run time method correlates time in different time bases used by interconnected units by timestamping a reference event with a time determined with respect to a first time base. The time is provided to a second interconnected unit that uses a second time base. A difference between the time measured by the first time base and in the second time base is determined. The difference is used to translate a time measured by the first clock to a time in a different time base at run time. An arrangement correlates different time bases of interconnected units, and includes a first unit that detects a reference event. A clock determines the reference time of the reference event in a first time base. A message unit sends the reference time to a second interconnected unit. The second interconnected unit uses a second time base, and a translation device correlates time measurements between the first time base and the second time base at run time.

摘要： A device collects messages, analog and digital signals from modules (e.g., ECUs, Electronic Controller Units) and sensors arranged on measurement objects in one or more distributed control systems. These systems may work with one or several protocols. The collected information can be of a considerable size, e.g., on the order of one several Gbytes, and can come from CAN or MOST systems arranged on machinery or a vehicle. A commentator system has a recording device for speech and/or image messages and these messages are converted to digital signals which may be distributed to a collection unit along with other signals obtained from the distributed system. Different tasks can be divided up between different experts or actors, and the analysis tasks themselves may be simplified.
