Description
Technical Field
The invention relates to the technical field of industrial control automation, in particular to a data exchange device and a data exchange network with a CAN bus incorporated into a time sensitive network.
Background
The CAN bus is introduced by Bosch company in germany, is originally used for data communication of measurement and execution components in automobiles, and is a bus technology which is widely applied at present. At present, most of bottom industrial fields are constructed on the basis of field buses, most of upper information management is connected by adopting Ethernet, how to realize the information acquisition sharing between the bottom industrial field buses and the upper information management, and control information distribution becomes the development trend of the current industrial control field. However, because the CAN bus belongs to the underlying field control bus and is not compatible with the ethernet protocol, it is a development trend to connect the device network based on the CAN bus into the information management network of the ethernet.
With the increasing real-time requirement of industrial field control and the increasing data volume, time-sensitive networks are produced. The conventional ethernet is designed mainly for solving the problem of reliable transmission of non-real-time data, and does not have the requirements of excessive order, time delay and the like. The time sensitive network is a standardized protocol which takes standard Ethernet as a network base and provides complete deterministic transmission, and has the following characteristics: the message delay of the switching network is ensured; the time sensitive data stream and the non-sensitive data stream can be transmitted in a mixed mode, and the transmission of the non-time sensitive data stream cannot influence the transmission delay of the time sensitive data stream; the loads of multiple protocols can be transmitted in the network simultaneously; network errors can be quickly diagnosed and repaired by obtaining accurate information at the source.
Currently, there are two main methods for the embedded gateway design of CAN and ethernet: one is a design method of adding an interface chip to a low-grade MCU, and the other is a design method of adding an EOS (real-time multi-task operating system) and an interface chip to a high-grade MCU. At present, a CAN Ethernet gateway is mainly transmitted in a UDP (user Datagram protocol) and TCP/IP (transmission control protocol/Internet protocol) mode, UDP is an unreliable transmission protocol, a sending end only sends out data, and whether a receiving end receives the data cannot be guaranteed. For the TCP/IP protocol, the IP network on which TCP depends has problems of packet loss, disorder, and unfixed delay, so that the requirements of deterministic and robust industries, such as factory automation, cannot be satisfied. For example, in the chinese patent application "CAN-ethernet communication gateway, data processing method and system" (patent No. CN103139052A), the scheme of the hardware protocol stack of W5100 is adopted, although the protocol conversion of CAN-ethernet CAN be realized, the real-time performance cannot be guaranteed; in the chinese patent application "CAN-ethernet communication conversion and data storage control method for train" (patent No. CN107124344A), data collected by a CAN bus is buffered, and the data is packed, stored and processed at a predetermined time interval, so that although the real-time problem in ethernet transmission CAN be improved to a certain extent, the problems of uncertainty of link delay, link data collision, and the like are worth further discussion.

Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "one" means not only "only one" but also a case of "more than one".
The data exchange device and the network of the invention, in which the CAN bus is merged into the time sensitive network, take the time sensitive network as a main structure, CAN merge the non-real-time data of the CAN bus into the time sensitive network through the information data exchange device which merges the CAN bus in the traditional industry into the time sensitive network, improve the data transmission rate under the condition of being compatible with the original control bus structure, and CAN configure the data into the real-time data and the non-real-time data.
The data exchange device of the CAN bus merged into the time sensitive network is realized based on the main control chip FPGA, the main control chip FPGA receives data of the CAN bus through the level conversion circuit, and data package work of the time sensitive Ethernet is completed in the main control chip FPGA. Because the Ethernet frame format is different from the CAN bus frame format, the CAN bus protocol frame format has two types: CAN standard frames and CAN extended frames. The standard frame of the CAN protocol is composed of 11 bytes, including frame information of the first 3 bytes and frame data of the last 8 bytes. And the extension frame of the CAN protocol consists of 13 bytes, including frame information of the first 5 bytes and frame data of the last 8 bytes. Because data in the CAN protocol is not sensitive to time, a hardware timestamp needs to be added to an ethernet message in a protocol data exchange device of a CAN protocol-to-time sensitive network. Because the time sensitive network comprises Ethernet bottom layer protocols such as bridging network basic standard, frame seizing standard, gate control scheduling standard, flow reservation protocol and frame seizing function, the data exchange device CAN configure the message type of the data received by the CAN bus under the condition of meeting all indexes of the time sensitive network, and select whether to send the data message preferentially according to the scheduling principle of the time sensitive network and the configuration level of the data message.
Referring to fig. 1, a time-sensitive network includes one or more CAN-TSN subnetworks 1, one or more TSN slaves 2, and a TSN switch 3, wherein each of the CAN-TSN subnetworks 1 includes any one of the data switching devices 11 and one or more CAN slaves 12 electrically connected thereto, the data switching device 11 is electrically connected to the TSN switch 3, and the TSN slaves 2 are respectively electrically connected to the TSN switch 3.
Here, in the time-sensitive network, the data switching device 11 is configured with parameters, and the configuration parameters may include: the working frequency of the CAN bus, the MAC address of the data exchange device, the type (period/non-period) of the Ethernet data, the grade (sending priority) of the Ethernet service quality, the number of messages carrying the CAN protocol and the like.
In the time-sensitive network, the time interval of the CAN-TSN sub-network 1 for processing data CAN be calculated according to the preset rate of the CAN slave station 12, and the period of sending CAN data from the TSN slave station 2 to the data exchange device 11 CAN be intensively configured according to the requirement according to the IEEE802.1Qcc standard of the TSN-sensitive network, so that the problem of CAN message overflow in the data exchange device 11 is solved.
Referring to fig. 2, the data exchange device 11 includes a CAN protocol parsing module 111, a CAN2TSN cache module 112, a CAN message flow control module 113, a TSN2CAN cache 115, and a TSN message parsing control module 114, wherein the CAN protocol parsing module 111, the CAN2TSN cache module 112, the CAN message flow control module 113, and the TSN message parsing control module 114 are electrically connected in sequence; the TSN2CAN cache 115 is electrically connected to the TSN message parsing control module 114 and the CAN message flow control module 113, respectively;
in this embodiment, the CAN protocol parsing module 111, the CAN2TSN cache module 112, the CAN message flow control module 113, the TSN2CAN cache 115, and the TSN message parsing control module 114 are all implemented inside the main control chip FPGA.
When the CAN slave station 12 needs to send a CAN protocol message to the TSN slave station 2, the CAN protocol parsing module 111 parses the CAN protocol message, and stores the parsed CAN protocol message in the CAN2TSN cache module 112, and data in the CAN2TSN cache module 112 is processed by the CAN message flow control module 113 and the TSN message parsing control module 114 in sequence and then output to the TSN slave station 2;
specifically, when the data cached by the CAN2TSN cache module 112 reaches a first preset cache threshold, the data in the CAN2TSN cache module 112 flows to the TSN message parsing control module 114 through the CAN message flow control module 113; then, the TSN packet parsing control module 114 packages the one or more CAN protocol packets into a TSN ethernet packet, where the TSN ethernet packet includes a 6Byte preamble, a 1Byte frame start, a 6Byte mac destination address, a 6Byte mac source address, a 4Byte802.1q tag, a 2Byte ethernet type, one or more CAN protocol packets, and a 4Byte redundancy check. The 4byte802.1qbia tag contains a priority reference, and the reference criterion of the priority is completed in the initialization configuration.
When the TSN slave station 2 needs to send a TSN ethernet packet to the CAN slave station 12, the TSN packet parsing control module 114 parses the TSN protocol packet, and stores the parsed TSN protocol packet in the TSN2CAN cache 115, and data in the TSN2CAN cache module 115 is processed by the CAN packet flow control module 113 and the CAN protocol parsing module 111 in sequence and then output to the CAN slave station 12.
Specifically, when the data cached by the TSN2CAN cache module 115 reaches a second preset cache threshold, the data in the TSN2CAN cache module 115 flows to the CAN message parsing control module 111 through the CAN message flow control module 113. The CAN message parsing control module 111 packetizes the TSN ethernet packet into one or more CAN protocol messages.
Because the rate of the TSN is far greater than that of the CAN bus, the data exchange device 11 controls the flow of data interacted between the CAN slave station 12 and the TSN slave station 2 through the CAN message flow control module 113; specifically, the release flow of the CAN bus data CAN be controlled according to the number of the initialization configuration messages carrying the CAN protocol.
The above-mentioned embodiments only express some exemplary embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
