Embodiment Construction

[0032] figure 1 A system 9 is shown which has 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 .

[0033] The detection unit 10 detects the data packets 5 from the CAN bus 2 . Subsequently, detection unit 10 supplies data packet 5 to computing unit 11 of control device 1 . Computing unit 11 creates network resource 6 in which data packet 5 is assembled. Each of the network resources 6 here forms a well-defined logical object, which can be called up 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 up by the receiving device 4 by means of a corresponding unambiguous address. The address is especially...

Abstract

The invention relates to a method for providing data packets (5) from a CAN bus (2), in particular a charging station for a motor vehicle. In order to permit a resource-saving and nevertheless securepossible way of providing data packets (5), steps are provided: detection of the data packets (5) from at least one component (3) of the CAN bus (2) by a detection unit (10) which is part of the CAN bus (3), creation of at least one web resource (6) which contains the data packets (5) in accordance with a predetermined specification by a computing unit (11), wherein only data packets (5) which arerelated in accordance with the predetermined specification are combined in the at least one web resource (6), transmission of a content of the at least one web resource (6) from the computing unit (11) to a receiving device (4) by means of a communication unit (12) via a data link (7) having a transmission protocol that differs from the CAN bus (2).

Description

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