Embodiment 1

[0044] figure 1 A schematic structural diagram of a gateway system provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the gateway system needs to improve the computing capability of the gateway and provide high real-time and high bandwidth, such as figure 1 As shown, the system includes: a processor 110, a controller 120, at least one switch 130, and a power supply module 140 for supplying power to the processor 110, the controller 120, and each switch 130, and the controller 120 includes Controller area network CAN transceiver, each of the switches 130 includes at least one port physical layer PHY transceiver; the controller 120 communicates with the first automotive device based on CAN communication through the CAN transceiver, and transmits and receives CAN through CAN information; each said switch 130 communicates with the second automotive device based on Ethernet communication through said PHY transceiver, and sends an...

Embodiment 2

[0056] figure 2 A schematic structural diagram of a gateway system provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above embodiments, and explanations of terms that are the same as or corresponding to the above embodiments will not be repeated here. Such as figure 2 As shown, in this embodiment, the system may further include: a processor 110, a controller 120, at least one switch 130, and a power supply module for supplying power to the processor 110, the controller 120, and each switch 130 140 and a power supply module management module, the controller 120 includes a controller area network CAN transceiver, each of the switches 130 includes at least one port physical layer PHY transceiver; the controller 120 communicates with CAN based The first automotive device is connected in communication, and sends and receives CAN information through CAN; each switch 130 communicates with the second automotive device based on Ethern...

Embodiment 3

[0068] image 3 It is a flow chart of an information sending and receiving method provided by Embodiment 3 of the present invention. This method can be applied to the gateway system described in any one of Embodiment 1 and Embodiment 2. This method can be executed by an information sending and receiving device, which can integrated in automotive systems such as image 3 As shown, the method specifically includes the following steps:

[0069] Step 310 , based on the detection of the working state of the power supply module by the power supply module management module, when the power supply module is working normally, continue to execute step 320 .

[0070]Specifically, when information is sent and received based on the gateway system, after the gateway system is turned on, the working status of the power supply module of the gateway system can be detected based on the power supply module management module. When the power supply module is working normally, the information can b...

Abstract

The invention discloses a gateway system and an information receiving and transmitting method, and relates to the vehicle-mounted system technology. The system comprises a processor, a controller, at least one switch and a power supply module for supplying power to the processor, the controller and the switches. The controller comprises a controller area network (CAN) transceiver; each switch comprises at least one port physical layer (PHY) transceiver; the controller is in communication connection with a first automobile device based on CAN communication through the CAN transceiver and receives and transmits CAN information through the CAN. Each switch is in communication connection with a second automobile device based on Ethernet communication through the PHY transceiver, and receives and transmits Ethernet information through the Ethernet; each switch is respectively in communication connection with the controller, the processor and other switches; the controller is in communication connection with the processor. According to the technical scheme, the problem that a traditional gateway is insufficient in operational capability is solved, and the gateway system with high real-time performance and high bandwidth is provided.

Description

technical field [0001] The embodiment of the present invention relates to vehicle system technology, in particular to a gateway system and an information sending and receiving method. Background technique [0002] With the continuous improvement of automobile intelligence and informatization, people not only use cars as transportation tools, but also continue to explore the intelligence of the automobile field and optimize the safety of the automobile field. The intelligent driving system is one of them. The intelligent driving system There are high requirements for real-time and security, and the requirements for bus width and data transmission rate are also getting higher and higher. [0003] In the prior art, a traditional network architecture can be constructed based on CAN (Controller Area Network). The controller, system basic chip, CAN transceiver and related circuits can form a traditional gateway. The communication form of the traditional gateway is mainly CAN Main...
