[0036] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0037] As described in the background, in the vehicle gateway circuit, line faults may occur, resulting in that sensor signals cannot be effectively returned to the vehicle gateway.

[0038] In view of this, in order to solve the above problems, the embodiments of the present application provide a self-repairing vehicle gateway, which is achieved by setting a main loop and a redundant loop, so as to improve the stability of sensor data transmission.

[0039] The self-repairing vehicle gateway provided by the present application will be described below:

[0040] As an implementation manner, please refer to Figure 1The self-repairing vehicle-mounted gateway comprises an MCU 110, a connector, a communication module 120, a data acquisition module 130, and a plurality of sensors 140, the MCU 110 is electrically connected with the connector, the communication module 120, and the data acquisition module 130 respectively; wherein the data acquisition module 130 is in communication connection with each sensor 140 through a main loop 161 and a redundant loop 162, the main loop 161 and the redundant loop 162 are also electrically connected with the MCU 110; when in a normal communication state, the data acquisition module 130 communicates with each sensor 140 through the main loop 161; when in an abnormal communication state, the MCU 110 controls the main loop 161 to be turned off and controls the redundant loop 162 to be turned on, so that the data acquisition module 130 communicates with each sensor 140 through the redundant loop 162.

[0041] On the one hand, after the main loop 161 and the redundant loop 162 are set, when the sensor 140 data is returned, even if the main loop 161 line fails, such as poor contact or line interruption, the sensor 140 data can be returned through the redundant loop 162, ensuring the stability of data transmission. At the same time, in the main loop 161 and the redundant loop 162, only one loop is always turned on, so that the data disorder can be avoided when the data is returned.

[0042] On the other hand, since the main loop 161 and the redundant loop 162 are introduced, the lines of the self-repairing vehicle-mounted gateway are relatively more, therefore, in order to facilitate the connection of the lines, the self-repairing vehicle-mounted gateway provided by the application further comprises a data acquisition module 130, which can be connected with each sensor 140 as middleware, and then connected with the MCU 110 through the data acquisition module 130, so as to simplify the line complexity of the MCU 110 and make the actual wiring more convenient.

[0043] As an implementation manner, please refer to Figure 2 The self-repairing vehicle-mounted gateway further comprises a connector, which is electrically connected with the data acquisition module 130 and the MCU 110 respectively. By setting the connector, the complexity of the line of the MCU 110 can be further reduced. That is, overall, the connector can reduce the complexity of the line of the MCU 110, the data acquisition module 130 can reduce the complexity of the line of the sensor 140, and then the MCU 110 and the data acquisition module 130 are connected, so that the connection of the lines of the self-repairing vehicle-mounted gateway is more simple overall.

[0044] In an implementation manner, please refer to Figure 3, the main loop 161 includes a first switch assembly 163, and the redundant loop 162 includes a second switch assembly 164; when the first switch assembly 163 is turned on, the second switch assembly 164 is turned off; when the second switch assembly 164 is turned on, the first switch assembly 163 is turned off. That is, in this application, the main loop 161 and the redundant loop 162 are set to one open and one closed, which ensures that only one loop is always turned on in each collection cycle, and there is no data duplication.

[0045] In this application, the main loop 161 and the redundant loop 162 are built by relays. Specifically, the first switch assembly 163 is a normally closed switch, and the second switch assembly 164 is a normally open switch. The self-repairing vehicle gateway further includes a coil 165, one end of which is electrically connected to the MCU 110, and the other end is grounded; when the coil 165 is not powered, the normally closed switch is turned on, and the normally open switch is turned off; when the coil 165 is powered, the normally closed switch is turned off, and the normally open switch is turned on.

[0046] On the one hand, through the setting of the relay, the effect of only one loop being turned on can be achieved at a low cost. On the other hand, since the MCU 110 directly controls the main loop 161 or the redundant loop 162 to be turned on through the coil 165, the control is more efficient. For example, when the MCU 110 does not receive the data returned by the sensor 140 within a certain time, the coil 165 can be directly powered to return the data through the redundant loop 162.

[0047] Of course, in an implementation manner, the self-repairing vehicle gateway can also be provided with an alarm device. Once the MCU 110 does not receive the data returned by the sensor 140 within a certain time, it indicates that the main loop 161 line may be damaged, and the MCU 110 can alarm to prompt the maintenance personnel to repair.

[0048] Alternatively, the MCU 110 provided by the application can use a chip with model number MCIMX6Y2CVM05AB, which can have 8-way UART, 2-way Ethernet MAC, 2-way USB2.0 with PHY, SDIO2.0, and other peripheral resources. On this basis, the self-repairing vehicle gateway further includes an RS485 transceiver, which is electrically connected to the connector and the MCU 110, and the MCU 110 communicates with the sensor 140 through the RS485 transceiver. The self-repairing vehicle gateway further includes an Ethernet module and a USB module, and the Ethernet module and the USB module are connected to the MCU 110 and the connector, respectively.

[0049] Through the implementation mode, the connector can be used for connecting the sensor 140 and used as an Ethernet and USB connecting port, universal connection of the MCU 110 chip part port is realized, which is beneficial to simplify the MCU 110 connection and realize miniaturization of the self-repairing vehicle gateway.

[0050] Moreover, the self-repairing vehicle gateway further comprises a storage module 150 connected with the MCU 110, wherein the storage module 150 is configured to store data of the sensor 140.

[0051] The MCU 110 chip communicates with the peripheral sensor 140 through the RS485 serial port, collects data information of various peripheral sensors 140 after the temperature sensor 140 returns temperature data, the voltage sensor 140 returns voltage data, and the current sensor 140 returns current data. Meanwhile, the real-time position of the vehicle is obtained through the GNSS receiver module, and then data processing is performed, and finally the obtained data is transmitted to the background through the 4G module. Meanwhile, when the 4G signal is lost, the storage module 150 can be used to store relevant data, and the data is transmitted to the background after the signal is restored.

[0052] Based on the above implementation mode, the embodiment of the present application further provides a vehicle comprising the self-repairing vehicle gateway.

[0053] In summary, the present application provides a self-repairing vehicle gateway and vehicle, the self-repairing vehicle gateway comprising a MCU, a connector, a communication module, a data acquisition module and a plurality of sensors, the MCU being electrically connected with the connector, the communication module and the data acquisition module; wherein the data acquisition module and each sensor are in communication connection through a main loop and a redundant loop, and the main loop and the redundant loop are also electrically connected with the MCU; when in a normal communication state, the data acquisition module communicates with each sensor through the main loop; when in an abnormal communication state, the MCU controls the main loop to be turned off and controls the redundant loop to be turned on, so that the data acquisition module communicates with each sensor through the redundant loop. Since the self-repairing vehicle gateway provided by the present application comprises a main loop and a redundant loop, and the sensors are connected through the main loop and the redundant loop, even if the main loop fails, the transmission of sensor data can be realized through the redundant loop, the self-repairing of the vehicle gateway is realized, and the stability of the operation of the vehicle gateway is improved.
