[0017] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of embodiments of the present application, rather than all embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work should belong to the protection scope of the present application.

[0018] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in other than the order illustrated or described herein. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0019] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related art will be introduced. The AUTBUS bus can also be called a two-wire bus, a field broadband bus or a two-wire industrial control bus, which is a two-wire non-bridge medium with multiple nodes, high bandwidth and time-sensitive industrial field bus, commonly used for real-time data and non-real-time data transmission and application in process control and discrete control and other automation control industrial fields, and compatible with ISO / IEC / IEEE 8802-3 Ethernet, IPv6 and other applications. The AUTBUS bus has the characteristics of high bandwidth and high real-time, long-distance high-reliability transmission, simple wiring and installation, and easy network maintenance, and supports the use of existing cable assets. AUTBUS uses bus networking, provides fixed bandwidth data services and supports variable bandwidth data services for burst data through bus pre-configuration or dynamic application. The AUTBUS bus can provide reliable and deterministic bearing for periodic sampling data, burst control, alarm and ISO / IEC / IEEE 8802-3 Ethernet format IPv4 / IPv6 data, and has the function of high-precision clock synchronization, and can provide deterministic data transmission service for time-sensitive and non-time-sensitive services based on time trigger. Therefore, the AUTBUS bus is widely used in industrial control, automotive electronics, aviation, smart city and other fields.

[0020] An AUTBUS bus system (also referred to as an AUTBUS bus network) can support multiple nodes, for example, 254 valid nodes, one of which is a control node (CN), and the rest of which can be user nodes, also referred to as terminal nodes (TN) or access terminals. The CN is responsible for the configuration and management of the entire network, and also includes bandwidth allocation for communication between TNs, and also includes recycling of system resources, etc. The TN uses the bandwidth resources obtained by allocation to exchange information and can complete the specified tasks. The minimum time slice unit in a two-wire network is a time slot (TimeSlot), 64 time slots (TimeSlot) form a frame (Frame), and 256 frames form a super-frame (Super-Frame). The CN can generate resource scheduling information and send the resource scheduling information to the terminal nodes, and the resource scheduling information can be used to specify the fixed time slots used by each terminal node.

[0021] In view of the many advantages of AUTBUS described above, AUTBUS has broad application prospects. However, the current AUTBUS network cannot realize information interaction with wireless terminals, and in the industrial field, some devices follow the WiFi module communication protocol, and the current AUTBUS network cannot meet the information interaction needs of some devices.

[0022] Figure 1 A structure diagram of a communication system based on an AUTBUS bus according to an embodiment of the present application is provided. The embodiment can be applied to the case where there is a need for information interaction with wireless terminals in the AUTBUS network. As shown in Figure 1 The communication system based on the AUTBUS bus 101 communicates based on the AUTBUS network, which includes the AUTBUS bus 102, the AUTBUS terminal 103, the conversion device 104, the wired terminal 105, and the wireless terminal 106. The conversion device 104 is configured as a terminal node of the AUTBUS network.

[0023] The wired terminal 105 accesses the AUTBUS network by accessing the AUTBUS terminal 103; and the wireless terminal 106 accesses the AUTBUS network by accessing the WiFi network to which the conversion device 104 belongs.

[0024] For example, the specific type of the wired terminal is not limited, such as an RS485 device, and the AUTBUS terminal can be provided with an interface matching the type of the wired terminal. The wired terminal can be connected to the AUTBUS terminal by connecting the interface, thereby accessing the AUTBUS network.

[0025] In the embodiment of the application, a conversion device (also referred to as a conversion bridge or a WiFi-AUTBUS conversion bridge) is additionally arranged in the AUTBUS network, and the conversion device can be configured as a terminal node of the AUTBUS network and can interact with the AUTBUS bus based on AUTBUS messages. The conversion device can realize one-way or two-way communication between the wireless terminal and the AUTBUS network, so that the wireless terminal device can become a node in the AUTBUS network. The wireless terminal in the embodiment of the application has the capability of accessing a WiFi network, that is, has the capability of communicating based on a WiFi protocol, and can also be referred to as a WiFi device. The WiFi device can be configured with a WiFi module, and the WiFi module can be used to connect to a wireless network access point (AP) in the WiFi network to which the conversion device belongs, so as to access the WiFi network to which the conversion device belongs and then access the AUTBUS network. The conversion device can convert between WiFi messages and AUTBUS messages. After receiving a message to be converted, the conversion device can cache the message to be converted, and obtain the message to be converted from the cache when conversion is needed. The specific conversion timing is not limited and can be determined according to the type of the message to be converted.

[0026] Optionally, the AUTBUS terminal and the conversion device can be the same device, that is, for one physical device, wired devices can be accessed and wireless terminals can also be accessed.

[0027] Optionally, the data content of the message for interaction in the communication system can be determined according to the actual application scenario. For example, in a scenario requiring sensor data collection, the data content of the message can include sensor data, which can be collected by a wired terminal or a wireless terminal. The sensor data can include image data collected by a camera.

[0028] The technical scheme of the embodiment of the application enriches the types of node devices in the AUTBUS network, effectively expands the use range and application scenarios of the AUTBUS network, and realizes communication between the wired terminal, the wireless terminal and other node devices in the AUTBUS network by using the AUTBUS terminal to realize access of the wired terminal in the AUTBUS network and introducing the conversion device as a bridge between the wireless terminal and the AUTBUS network.

[0029] In some embodiments, the conversion device can be optimized for a scenario in which a wireless terminal in one WiFi network is connected to a terminal node of the AUTBUS network, and a wireless terminal in another WiFi network is connected to another terminal node of the AUTBUS network. For example, a conversion device is configured to receive a first WiFi message sent by a first wireless terminal in a first WiFi network, split the first WiFi message into at least one first AUTBUS message, and send the at least one first AUTBUS message to the AUTBUS bus, wherein the first WiFi message is destined to a second wireless terminal in a second WiFi network. The conversion device is further configured to receive the at least one first AUTBUS message forwarded by the AUTBUS bus, assemble the at least one first AUTBUS message into a corresponding second WiFi message, and send the second WiFi message to the second wireless terminal. In this way, the conversion device can convert the WiFi message and the AUTBUS message by splitting and assembling, thereby enabling information exchange between the wireless terminals in the two different WiFi networks. The first WiFi network and the second WiFi network are different, and the conversion device in the first WiFi network can be referred to as a first conversion device, and the conversion device in the second WiFi network can be referred to as a second conversion device.

[0030] For example, the length of a WiFi message is usually not fixed, and the maximum number of bytes that can be carried by a single time slot of the AUTBUS bus is limited. Therefore, the conversion of the message can be performed by splitting the data packet.

[0031] Optionally, splitting the first WiFi message into at least one first AUTBUS message can include determining the number of splits based on the length of the first WiFi message, and splitting the first WiFi message into at least one first AUTBUS message based on the number of splits. For example, if the length of the first WiFi message is less than or equal to a preset length, the number of splits is one, i.e., the first WiFi message is split into one first AUTBUS, which can also be understood as converting the first WiFi message into one first AUTBUS message. If the length of the first WiFi message is greater than the preset length, the number of splits is greater than one, i.e., the first WiFi message is split into at least two first AUTBUS messages, i.e., the number of first AUTBUS messages is at least two.

[0032] Optionally, the split first AUTBUS message can contain the node identifier of the destination node, i.e., the node identifier of the second wireless terminal. When the number of the first AUTBUS messages is at least two, the node identifier of the second wireless terminal can be included in each of the first AUTBUS messages, so that the AUTBUS bus can identify all the split first AUTBUS messages that need to be forwarded to the second wireless terminal after the conversion device sends the first AUTBUS messages to the AUTBUS bus. The node identifier can be a node number, such as nodeid.

[0033] For example, if the number of the first AUTBUS messages is one, the conversion device can directly convert the first AUTBUS message into a second WiFi message. If the number of the first AUTBUS messages is at least two, the conversion device can splice the at least two first AUTBUS messages into a complete second WiFi message.

[0034] In some embodiments, the number of the first AUTBUS messages is multiple; and the assembling of the at least one first AUTBUS message into a corresponding second WiFi message includes determining the number and the assembling order of the first AUTBUS messages according to the header information in each of the first AUTBUS messages, and assembling the first AUTBUS messages into a second WiFi message according to the number and the assembling order of the first AUTBUS messages. This setting has the advantage of ensuring the accuracy of the assembled message.

[0035] For example, each of the first AUTBUS messages can be regarded as a packet of the first WiFi message before splitting. The header information can include the packet number, the total number of packets, the start packet identifier, and the end packet identifier, so that the number and the assembling order can be determined according to the header information.

[0036] Optionally, the number of the conversion devices is not limited and can be one or more. For the case that there are at least two WiFi networks in the communication system, the number of the conversion devices can be consistent with the number of the WiFi networks.

[0037] In some embodiments, the conversion device is configured as a wireless network access point in the WiFi network to which it belongs. This setting has the advantage that the wireless terminal can directly communicate with the conversion device without the need for the wireless access point to forward, ensuring the efficiency and success rate of the WiFi message transmission.

[0038] In some embodiments, the AUTBUS terminal or the wired terminal accessing the AUTBUS terminal can be optimized for a scenario in which a wireless terminal is connected through a terminal node of the AUTBUS network, and in which a source node of a message is the AUTBUS terminal or the wired terminal accessing the AUTBUS terminal, and a destination node of the message is a wireless terminal in a WiFi network. For example, the AUTBUS terminal is configured to send at least one second AUTBUS message to the AUTBUS bus, wherein the source node corresponding to the at least one second AUTBUS message includes the AUTBUS terminal and / or the wired terminal accessing the AUTBUS terminal, and the destination node corresponding to the at least one second AUTBUS message includes a third wireless terminal in a third WiFi network to which the conversion device belongs; and the conversion device is configured to receive the at least one second AUTBUS message forwarded by the AUTBUS bus, assemble the at least one second AUTBUS message into a corresponding third WiFi message, and send the third WiFi message to the third wireless terminal. In this way, the AUTBUS terminal or the wired terminal accessing the AUTBUS terminal sends an AUTBUS message to the conversion device through the AUTBUS bus, the conversion device assembles the AUTBUS message to obtain a WiFi message to be sent to the wireless terminal, and information interaction between the AUTBUS terminal or the wired terminal accessing the AUTBUS terminal and the wireless terminal in the AUTBUS network is successfully achieved.

[0039] In some embodiments, the AUTBUS terminal in the AUTBUS network is configured to receive a message sent by the wired terminal, split the message into at least one AUTBUS message to obtain a second AUTBUS message, and forward the second AUTBUS message to the AUTBUS bus.

[0040] In some embodiments, the optimization can be performed for the wireless terminal, the AUTBUS terminal of the AUTBUS network, or the wired terminal accessing the AUTBUS terminal, in terms of how the terminal nodes of the AUTBUS network are connected. In this scenario, the source node of the message is the wireless terminal in the WiFi network, and the destination node of the message is the AUTBUS terminal or the wired terminal accessing the AUTBUS terminal. For example, the conversion device is configured to receive a fourth WiFi message sent by a fourth wireless terminal in a fourth WiFi network, split the fourth WiFi message into at least one third AUTBUS message, and send the at least one third AUTBUS message to the AUTBUS bus. The fourth WiFi message corresponds to a destination node including the AUTBUS terminal and / or the wired terminal accessing the AUTBUS terminal. The AUTBUS terminal is configured to receive the at least one third AUTBUS message forwarded by the AUTBUS bus, and / or to receive the at least one third AUTBUS message forwarded by the AUTBUS bus and forward the at least one third AUTBUS message to the wired terminal accessing the AUTBUS terminal. In this way, the WiFi message sent by the wireless terminal is unpacked by the conversion device and forwarded to the AUTBUS bus, and then forwarded to the AUTBUS terminal or the wired terminal accessing the AUTBUS terminal by the AUTBUS bus, thereby successfully realizing the information interaction between the wireless terminal and the AUTBUS terminal or the wired terminal in the AUTBUS network.

[0041] In this way, the AUTBUS terminal can group the at least one third AUTBUS message into a corresponding message according to the message protocol supported by the wired terminal after receiving the at least one third AUTBUS message, and send the message to the wired terminal.
