As shown in fig. 1, the present embodiment provides an on-board gateway controller 1, which mainly includes: microprocessor 11, power module 12, communication module 13, signal transmission module 14. Further, the on-board gateway controller 1 further includes: antenna selector 15, internal backup antenna 16, external antenna 17. The respective operation modules will be described in detail below with reference to fig. 1.
In this embodiment, the microprocessor 11 specifically uses a single chip microcomputer (MCU for short). In other embodiments, the microprocessor 11 may also be a Central Processing Unit (CPU), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, or the like.
The power module 12 is electrically connected to each working module in the vehicle-mounted gateway controller 1, so that external power supply introduced to the vehicle-mounted gateway controller 1 is independently supplied to each working module. Preferably, the battery module 12 contains a backup battery, when the external power supply of the vehicle gateway controller 1 is normal, the power module 12 charges the backup battery while independently supplying power to each working module, and the backup battery does not work; when the external power supply of the vehicle gateway controller 1 is abnormal, such as the situation that the external power supply disappears or the voltage is particularly low, the standby battery starts to independently supply power to each working module.
In this embodiment, the communication module 13 is a wireless communication module, for example, wireless communication can be established with the outside through wireless networks such as 2G/3G/4G/5G network, WiFi, and/or Bluetooth, so as to transmit and receive data of each communication network of the entire vehicle and important data locally acquired by the vehicle-mounted gateway controller 1 to terminal platforms such as an external physical server and a cloud server in real time. Preferably, the communication module 13 further comprises a GPS positioning module, which can obtain the current position of the vehicle in real time.
In detail, the microprocessor 11 performs summary processing on signals and data collected from each working module and then sends the signals and data to the communication module 13, and the communication module 13 selects a 4G or 5G or WIFI or higher-speed wireless network communication mode to quickly send the signals and data to a terminal platform for a terminal client to monitor the vehicle state in real time. Similarly, the terminal platform may also send a control command or a data packet sent by the terminal client to the on-board gateway controller 1 to perform corresponding command control on the on-board gateway controller.
The signal transmission module 14 may specifically include: one or more paths of CAN bus modules, one or more paths of LIN bus modules, an analog signal acquisition module, a digital quantity output module and the like, and the modules CAN be completely selected, added and deleted by technicians in the field according to actual needs, for example, 5 paths of CAN buses, 3 paths of LIN buses, 5 paths of analog signal acquisition modules, 10 paths of digital signal acquisition modules, 2 paths of digital quantity outputs including high-side output and low-side output CAN be set by the CAN bus modules, the LIN buses and the analog signal acquisition modules.

The analog signal acquisition module and the digital signal acquisition module are responsible for acquiring local important signals and summarizing the local important signals to the microprocessor 11. In detail, the analog signal acquisition module is controlled by the microprocessor 11, and can detect external sensor signals such as acceleration sensor signals, and transmit the signals to the microprocessor 11, so that the microprocessor 11 can make corresponding action decisions according to the signals. The digital signal acquisition module is controlled by the microprocessor 11 and can detect external switching value signals such as power supply signals, key enabling signals and the like. The digital output module is controlled by the MCU, and can control an output indicator (such as an LED lamp of a console in a vehicle) to remind a user of the current working state of the gateway controller 1 on the vehicle, and certainly can also provide certain driving output for other loads, which are not listed herein.
The antenna selector 15 is electrically connected to the communication module 13 on one hand, and is electrically connected to the on-board internal backup antenna 16 and the external antenna 17 disposed outside the on-board gateway controller 1 on the other hand, respectively, and it can be determined whether to use the internal backup antenna 16 or the external antenna 17 according to the current environment or working condition of the transmission of the communication module 13, specifically, if the communication module 13 detects that the external antenna 17 is abnormal, the internal backup antenna 16 is activated, wherein the performance of the internal backup antenna 16 may be lower than that of the external antenna 17, but the normal operation of the wireless network communication can be ensured.
As shown in fig. 2, the present embodiment provides an operation mode switching method, which is applied to the aforementioned vehicle gateway controller 1, and is specifically executed by the microcontroller 11, and includes the following steps:
s21: and under a normal working mode, enabling the power supply module of the vehicle-mounted gateway controller to independently supply power for each working module. According to the foregoing, the power module introduces external electric energy to individually supply power to each working module. When the external power supply is normal, the power supply module provides working voltage for the microcontroller, the communication module, the signal transmission module and the like and charges the standby battery; and when the external electric energy is detected to be abnormal, the standby battery is started to replace the power supply module to supply power for the microprocessor, the communication module and the signal transmission module independently.
S22: and when a sleep request is received, such as when a vehicle key off signal is acquired, the normal operation mode is switched to a low power consumption operation mode.
In the low power consumption mode, the power supply module stops supplying power to the signal transmission module, and only the power supply to the microcontroller and the communication module is reserved, so that the communication module can be ensured to have functions of reporting abnormal power failure reasons and the like while saving electricity. Meanwhile, under the control of the microcontroller, the power supply module periodically (for example, every 1ms to 10ms) restores the power supply to the signal transmission module, so as to wake up the signal transmission module to be put into operation, and enable the signal transmission module to detect whether an external signal exists; and if so, switching from the low-power-consumption working mode to the normal working mode.
Further, the method for converting the operating mode further includes S23:
in the low power consumption operating mode, if it is detected that the signal transmission module does not receive an external signal within a preset time (for example, within 10 seconds), the low power consumption operating mode is switched to a sleep operating mode. In the sleep mode, the power supply module is further enabled to stop supplying power to the communication module in addition to the power supply module turning off the power supply to the signal transmission module in the low power consumption mode, so as to achieve the purpose of further saving power.
Further, the method for converting the operating mode further includes S24:
in the sleep mode, the power module periodically (e.g., every 1ms to 10ms) resumes power supply to the signal transmission module and the communication module under the control of the microcontroller to detect whether the signal transmission module and the communication module receive an external signal when the signal transmission module and the communication module are woken up. And if the signal transmission module or the communication module receives an external signal, the dormant working mode is switched to the normal working mode.
All or part of the steps for implementing the above method embodiments may be performed by hardware associated with a computer program. Based upon such an understanding, the present invention also provides a computer program product comprising one or more computer instructions. The computer instructions may be stored in a computer readable storage medium.
