Description

Technical Field

[0001] This application relates to the field of data processing, and particularly to an Ethernet conversion device and a vehicle. Background Art

[0002] With the rapid development of automotive technology, especially with the increasing trend of intelligent, connected, and automated transformation, it has greatly promoted the progress and application of in-vehicle Ethernet technology. In particular, the application of technologies such as ADAS (Advanced Driver Assistance System), autonomous driving, infotainment systems, and vehicle networking has led to a sharp increase in the amount of data that needs to be processed and transmitted inside the vehicle.

[0003] Traditional automotive bus systems (such as the high-speed CAN communication standard defined by the ISO 11898 standard with a communication rate of 125 kbps to 1 Mbps) are gradually showing their limitations in bandwidth and cannot meet the requirements of these high-data-throughput applications. In-vehicle Ethernet, with its high-bandwidth characteristics (communication rates can reach 100 Mbps, 1000 Mbps, or even higher), has become an ideal solution. With the progress of technology and the growing demand of consumers for intelligent connected vehicles, a large number of in-vehicle Ethernet-related automotive accessories have emerged in the market. As a key communication infrastructure, in-vehicle Ethernet is gradually replacing the traditional CAN bus and becoming an efficient data transmission pipeline for connecting various electronic control units (ECUs), sensors, and actuators inside and outside the vehicle.

[0004] To apply these in-vehicle Ethernet devices to more general industrial automation and control fields, it is necessary to achieve seamless conversion between in-vehicle Ethernet technology and industrial Ethernet technology. This is because, although in-vehicle Ethernet is mainly designed for high-speed data communication inside the vehicle and has the characteristics of low latency and high bandwidth, there are certain differences between its standards and protocols (such as BroadR-Reach or OPEN Alliance TC8) and industrial Ethernet (which follows the IEEE 802.3 standard and supports various industrial protocols such as PROFINET, EtherCAT, Modbus TCP, etc.) widely used in fields such as factory automation and intelligent buildings. Therefore, in order to promote the interoperability and compatibility of in-vehicle Ethernet devices in a wider range of industrial scenarios, it is necessary to develop specialized converter or gateway devices. These devices need to be able to intelligently bridge and convert between in-vehicle Ethernet protocols and industrial Ethernet protocols to ensure the accurate and lossless transmission of data packets, and at the same time, handle the different requirements of both at the physical layer, data link layer, and network layer, such as the support requirement for time-sensitive networking (TSN) in industrial Ethernet and the stability and reliability requirements in harsh environments.

[0005] Therefore, it is necessary to provide improved technical solutions to overcome the above technical problems existing in the prior art. Summary of the Invention

[0031] As Figure 1 shown, an Ethernet conversion device provided by an embodiment of the present application includes:

[0032] An Ethernet conversion module 110 configured to connect to an in-vehicle Ethernet interface and convert an in-vehicle Ethernet signal into an industrial Ethernet signal;

[0033] A fault detection module 120 connected to the Ethernet conversion module 110, configured to detect a fault of the Ethernet conversion module 110 and generate a fault signal when the fault of the Ethernet conversion module 110 is detected; a main control module 130 connected to the Ethernet conversion module 110 and the fault detection module 120; an alarm module 140 connected to the main control module 130; and a remote monitoring module 150 connected to the main control module 130.

[0034] The main control module 130 is configured to, in response to receiving the industrial Ethernet signal from the Ethernet conversion module 110, send the industrial Ethernet signal to the remote monitoring module 150 for display; and is further configured to, in response to receiving the fault signal from the fault detection module 120, control the alarm module 140 to issue an alarm.

[0035] It can be understood that the Ethernet conversion module 110 is used to convert the signals of Ethernet devices originally limited to the in-vehicle environment, that is, by seamlessly converting in-vehicle Ethernet signals into more general industrial Ethernet signals. By adopting a standardized communication protocol, different devices can communicate and cooperate with each other, improving the interoperability and compatibility of the devices. Devices originally only used in vehicles can cross platform barriers and be applied to various industrial automation fields, such as manufacturing, logistics, energy, transportation, etc., with broad application prospects and market demands. In summary, the method of converting in-vehicle Ethernet signals into industrial Ethernet signals has the advantages of high reliability, high bandwidth, easy scalability, strong interoperability, convenient management and wide application, and is a modern communication technology with broad application prospects and market demands.

[0036] Furthermore, the function of the Ethernet conversion module 110 in converting in-vehicle Ethernet signals into industrial Ethernet signals in this embodiment is further described. The Ethernet conversion module 110 is connected to the main control module 130 and is used to convert the in-vehicle Ethernet signals received from the in-vehicle Ethernet interface into industrial Ethernet signals and send the industrial Ethernet signals to the main control module 130.

[0037] Furthermore, the function of controlling the alarm module 140 to issue an alarm in response to receiving the fault signal from the fault detection module 120 in this embodiment is further described. The fault detection module 120 is connected to the main control module 130 and is used to send a fault signal to the main control module 130 when the sensors in the fault detection module 120 detect abnormal circuit data information; the main control module 130 is connected to the alarm module 140 and is used to send a control signal to the alarm module 140 when receiving the fault signal, thereby controlling the alarm module 140 to work.

[0038] In one embodiment, the Ethernet conversion module 110 includes a first Ethernet conversion unit and a second Ethernet conversion unit.

[0039] In one embodiment, the first Ethernet conversion unit and the second Ethernet conversion unit are connected to each other and are respectively connected to the main control module, wherein the second Ethernet conversion unit is connected to the in-vehicle Ethernet interface.

[0040] It can be understood that the in-vehicle Ethernet interface is used to receive various in-vehicle Ethernet data. The in-vehicle Ethernet data may include data to be transmitted in the vehicle, such as vehicle log data, etc. The type of in-vehicle Ethernet data is not limited in this application.

[0041] Preferably, the first Ethernet conversion unit includes an 88E1512 chip, which is a high-performance Ethernet physical layer transceiver chip launched by Marvell Corporation in the United States and is widely used in the network interface circuit design of various Ethernet devices, such as routers, switches, network cards, Power over Ethernet (PoE) devices, etc.; the second Ethernet conversion unit includes an 88Q2112, which is a 100 / 1000BASE-T1 Ethernet physical layer transceiver (PHY) defined based on IEEE 802.3bw and IEEE 802.3bp, realizing signal transmission on a single pair of twisted pairs. This chip uses a standard digital CMOS process and combines all the required active circuits inside to achieve simultaneous reception and transmission of data on a pair of twisted pairs, well realizing various in-vehicle applications.

[0042] In one embodiment, the fault detection module 120 includes at least one of a temperature sensor, a voltage sensor, and a current sensor connected to the main control module.

[0043] It can be understood that the temperature sensor includes a thermistor, and the current sensor includes a Hall current sensor. The resistance value of the thermistor will increase or decrease with the change of temperature, resulting in a change in the voltage after the voltage-dividing resistor, so that the main control module 130 detects an abnormal voltage and then judges the temperature abnormality; the working principle of the Hall current sensor is based on the interaction between the Hall effect and current. When current passes through the wire carrying the Hall element, there will be an influence of magnetic field on both sides of the wire, and then a potential difference is generated. When the Hall sensor detects an abnormal current value in the circuit, an electrical signal will be generated and sent to the main control module 130. The voltage sensor can be a Hall voltage sensor, an opto-isolated voltage sensor, an electrically isolated voltage sensor, a voltage transformer, etc.

[0044] In one embodiment, the alarm module 140 includes an audio signal alarm unit, an optical signal alarm unit, and a triode.

[0045] In one embodiment, one end of the audio signal alarm unit is connected to the negative pole of the optical signal alarm unit, and the other end is connected to the emitter of the triode; the positive pole of the optical signal alarm unit is respectively connected to the base of the triode and the main control module through a protection resistor.

[0046] Preferably, the main control module 130 includes a GD32F303CBT6 chip, which adopts - The M4 32-bit processor provides up to 3072 KB of on-chip flash memory and 96 KB of SRAM memory. A wide range of enhanced I / O and peripherals are connected to two APB buses. These devices provide up to three 12-bit 2.6 MSPS ADCs, 2 12-bit DACs, up to 10 general-purpose 16-bit timers, 2 16-bit PWM advanced timers, and two 16-bit basic timers, as well as standard and advanced communication interfaces: up to 3 SPIs, 2 I2Cs, 3 USARTs and 2 UART I2Ss, USBD, CAN, and SDIO. The device operates on a 2.6 to 3.6 V power supply and is available in temperature ranges of (-20 to +85 °C) / (-40 to +85 °C) / (-40 to +105 °C). The above features make the GD32F303 CBT6 chip suitable for a wide range of interconnections and advanced applications, especially in industrial control, motor drive, consumer and handheld devices, human-machine interfaces, security and alarm systems, POS, automotive navigation, Internet of Things, and other fields.

[0047] In one embodiment, the remote monitoring module includes a display screen for displaying data on the real-time change status of the industrial Ethernet signal.

[0048] It can be understood that the user remotely views real-time data, historical records, and alarm information through the Web interface of the remote monitoring module 150 after authentication and can execute control commands. Once an anomaly is detected, the system generates a detailed fault log, which contains key information such as the time of the fault occurrence, the specific location, possible causes, and the scope of influence, providing a basis for subsequent fault diagnosis and repair. At the same time, this application not only has on-site audible and visual alarms but also automatically triggers remote alarms, and immediately conveys the fault information to the remote monitoring center or the designated maintenance team through the remote monitoring module 150.

[0049] Preferably, the remote monitoring module 150 includes an ESP8266 chip, a low-cost Wi-Fi chip developed by Espressif Systems. It integrates a processor, a Wi-Fi module, memory, and other peripherals. The ESP8266 chip communicates with other devices (such as microcontrollers) through a serial interface (such as UART or SPI) and provides connection and communication functions with the Wi-Fi network.

[0050] In one embodiment, the device further includes a switching module connected to the main control module 130 for switching the working mode of the Ethernet conversion module 110.

[0051] In one embodiment, the switching module includes a DIP switch connected to the main control module through a protection resistor.

[0052] Optionally, the switching module includes a DIP switch for switching between the master mode and the slave mode and for switching at different transmission rates. When directly transmitting data using the in-vehicle Ethernet interface, it is necessary to switch the master-slave mode to perform data transmission and adjust the transmission rate, such as two different gears of gigabit or hundred megabit. Simply operating through the DIP switch can switch different working modes and transmission rates, improving the adaptability of the system and the user experience.

[0053] Through the above Ethernet conversion device, the Ethernet device signal originally limited to the in-vehicle environment can be effectively converted into an industrial Ethernet signal, expanding the usage range and application scenarios of in-vehicle devices; at the same time, combined with multiple sensors and remote monitoring terminals, relevant parameters of the circuit are monitored in real time, and relevant data is sent to the user, reducing the downtime and maintenance cost of the device, thus ensuring the continuity and stability of production and improving the efficiency of maintenance.
