Embodiment Construction

[0036] figure 1 A system 9 is shown with a CAN bus 2 , a control device 1 and a receiving device 4 . The control device 1 is configured to detect data packets 5 from at least one component 3 of the CAN bus 2 . For this purpose, the control device 1 has a detection unit 10 which is part of the CAN bus 2 . In other words, the detection unit 10 is connected to the CAN bus 2 .

[0037] The detection unit 10 detects the data packets 5 from the CAN bus 2 . Next, the detection unit 10 supplies the data packet 5 to the calculation unit 11 of the control device 1 . The computing unit 11 creates a network resource 6 in which the data packets 5 are combined. Each of the network resources 6 here forms a well-defined logical object which can be called by the receiving device 4 via the communication unit 12 via the data connection 7 . In particular, each of the network resources 6 can be called by the receiving device 4 by means of a corresponding unambiguous address. The address is e...

Abstract

The invention relates to a method for providing data packets ( 5 ) from a CAN bus ( 2 ), in particular for a charging station of a motor vehicle. In order to realize a resource-saving and yet secure possibility for providing data packets (5), the following steps are provided: - Detect at least A data package (5) of a component (3), - at least one network resource (6) containing the data package (5) is created by the computing unit (11) according to predetermined specifications, wherein only the relevant data packages according to the predetermined specification (5) Combining in said at least one network resource (6), - connecting said at least one network resource (6) to The content of is transmitted from said computing unit (11) to a receiving device (4).

Description

technical field [0001] The invention relates to a method for providing data packets from a CAN bus, eg for a charging station of a motor vehicle. A second aspect of the invention relates to a control device for providing data packets from a CAN bus. A third aspect of the invention relates to a system for providing data packets from a CAN bus. Background technique [0002] The CAN bus is also being used more and more frequently in addition to its traditional use in motor vehicles due to the increasing networking of technical devices. Here, the CAN bus can be used for the networking of individual components or modules within the technical system, and Ethernet or network technologies based on Ethernet can be used to connect the technical system to the outside, for example to the rear terminal, connected to the Internet and / or connected to a server device. The individual components of the technical system are often produced by different manufacturers for various purposes. Th...
