In addition, the technical features mentioned in the different embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.
WOL (Wake On LAN) is a technique that functions to enable a device that has entered a sleep or power-off state to issue a command to the device through the other end of a LAN (e.g., ethernet), to Wake up from the sleep state, to return to an operational state, or to transition from the power-off state to the power-On state.
WOL technology is now commonly used in PCs, and typically WOL functionality can be enabled in the BIOS of the computer. The conventional WOL function is basically used for LAN wake-up of a PC and remote wake-up by a router, and the hardware requirement for the LAN must support the WOL function. When the PC enters standby or sleep, the remote application program can only send the magic packet to wake up the PC with the WOL function started. WOL is also currently being applied to in-vehicle devices that mount an in-vehicle ethernet chip having a WOL function.
The vehicle-mounted Ethernet is a novel local area network technology for connecting electronic units in a vehicle through the Ethernet, and different from the traditional Ethernet which uses 4 pairs of unshielded twisted pair cables, the vehicle-mounted Ethernet can realize the transmission rate of 100Mbit/s or even 1Gbit/s on a single pair of unshielded twisted pair cables, and simultaneously also meets the requirements of the automobile industry on high reliability, low electromagnetic radiation, low power consumption, bandwidth allocation, low delay, synchronous real-time property and the like.
Now, with the popularization of the vehicle-mounted ethernet technology, more and more vehicle enterprises begin to deploy the vehicle-mounted ethernet function on self-developed vehicle types, and the deployed vehicle-mounted ethernet is not the application of a local network any more, but integrates entertainment, security and communication subsystems to construct a vehicle-mounted ethernet total system.
The function of the former automobile is simple, the required network bandwidth is smaller, but at present, due to the application of new technologies such as ADAS, infotainment system, active safety system and the like and the enhancement of the traditional technologies, the network requirement in the automobile is increased rapidly and exceeds the capacity limit of the traditional vehicle-mounted networks such as CAN, Flexray and the like, so that the automobile enterprise pursues a faster and stronger communication mode, and the data communication in the automobile is increased from the traditional several Kbps and several Mbps to the current 100Mbps and even 1000Mbps and the like.
When the number of vehicle devices is increased and the vehicle-mounted communication rate is increased, a particularly strict requirement is generated on the power consumption of the vehicle, and the requirement on the overall power consumption of the vehicle is more and more strict along with the gradual transition of the vehicle from the traditional fuel field to the hybrid field to the pure electric field, and particularly, the loss of the power consumption is required to be better reduced when the vehicle is in a flameout state. At this time, when the vehicle is in a flameout state, the vehicle-mounted device enters a low power consumption sleep mode to reduce the overall power consumption of the vehicle.
Because the traditional WOL function has larger limitation, the vehicle-mounted Ethernet can only be woken up by sending a magic packet (the format of the magic packet is that the MAC address is the MAC address of the woken-up device, the IP address is 255.255.255.255, and the PORT is self-defined). Specifically, one broadcast frame is implemented with a special network message of a magic packet, which includes a 48-bit MAC address repeated 16 times. According to the awakening mode for awakening the vehicle-mounted Ethernet by sending the magic packet, as the MAC address is required to be repeated for many times, the vehicle-mounted equipment which enters the low power consumption modes such as dormancy and the like cannot be awakened quickly to enter the working mode quickly, the awakening time is long, and the user experience is influenced.
In view of the above, the present application provides a method for waking up a vehicle device on a network, where a received network wake-up packet is processed according to a preset access control list rule, and whether to trigger an interrupt of the vehicle device to wake up the vehicle device is determined according to a processing result, and a format of the network wake-up packet is also changed from a conventional magic packet to a UDP packet and a fixed port number. Therefore, the network awakening data packet can be sent more flexibly, the Access Control List (ACL) function is used for simulating the network awakening (WOL) function to quickly awaken the vehicle-mounted equipment which enters the low power consumption modes such as the dormancy mode, the awakening time of the vehicle-mounted equipment is shortened, the vehicle-mounted equipment can quickly enter the working mode, and the user experience is improved.
For the purpose of facilitating an understanding of the above inventive concepts of the present application, reference is made to the following detailed description of the embodiments taken in conjunction with the accompanying drawings.
In one embodiment, as shown in fig. 1, the present application provides a method for network wake-up of a vehicle device, where the method includes:
s1, receiving a network Wake-On (WOL) data packet which is sent by the upper computer and used for waking up the vehicle-mounted equipment;
and S2, processing the received network awakening data packet according to a preset configured Access Control List (ACL) rule, and determining whether to trigger the interruption of the vehicle-mounted equipment according to a processing result so as to awaken the vehicle-mounted equipment.
In this embodiment, a network wake-up (WOL) packet sent by an upper computer and used for waking up the vehicle-mounted device is received, the received network wake-up packet is processed according to a preset Access Control List (ACL) rule, and whether to trigger an interrupt of the vehicle-mounted device is determined according to a processing result, so as to wake up the vehicle-mounted device. Therefore, the Access Control List (ACL) function can be used for simulating a network wake-up (WOL) function to quickly wake up the vehicle-mounted equipment which enters low-power-consumption modes such as dormancy and the like, the wake-up time of the vehicle-mounted equipment is shortened, the vehicle-mounted equipment can quickly enter a working mode, and the user experience is improved. The system is particularly suitable for vehicle-mounted equipment without WOL function in the field of vehicle-mounted Ethernet, such as TBOX (Telematics Box), OBU (On board Unit), ECU (Electronic Control Unit, also called traveling computer, vehicle-mounted computer) or vehicle-mounted router.
In one embodiment, in the step S1, the receiving unit receives a network wake-up packet sent by the upper computer for waking up the vehicle-mounted device.
Specifically, the On-board device includes a device that carries an ethernet chip having an Access Control List (ACL) function and configures an IP address, and includes a TBOX (Telematics Box), an OBU (On board Unit), an ECU (Electronic Control Unit, also called a vehicle computer or an On-board computer), or an On-board router.
The in-vehicle device may be a hardware device without wake on network (WOL) functionality.
And when the vehicle-mounted equipment is in a dormant state, the ACL function of the Ethernet chip is enabled.
The network awakening data packet is generated and sent by an upper computer used for awakening the vehicle-mounted equipment. Wherein the Wake-On-LAN (WOL) packet has a format including: UDP (User data packet Protocol) packets and fixed port numbers.
For example: the network awakening data packet format is as follows: uwolf. exe-m 112233445566192.168.2.1.
Wherein uwolc.exe is the Sock data packet of UDP, 112233445566 is the MAC address, 192.168.2.1 is the IP address of the IP gateway.
And the IP gateway and the IP address are configured on the vehicle-mounted equipment to be awakened.
Before the network awakening data packet is sent to the vehicle-mounted equipment, the upper computer packages the network awakening data packet through a TCP/IP protocol, and then the upper computer sends the network awakening data packet which is packaged through the TCP/IP protocol to the vehicle-mounted equipment. And the network data packet received by the vehicle-mounted equipment is a network awakening data packet packaged by TCP/IP.
In this embodiment, the format of the wake-on-lan packet is changed from a conventional magic packet to a UDP packet and a fixed port number, so that the wake-on-lan packet is more flexibly sent.
In an embodiment, as shown in fig. 2, in the step S2, the received network wake-up packet is processed according to a preset access control list rule, and whether to trigger an interrupt of the vehicle-mounted device is determined according to a processing result, so as to wake up the vehicle-mounted device.
Specifically, the received network wake-up data packet is processed according to a preset access control list rule, and whether to trigger the interruption of the vehicle-mounted device is determined according to a processing result so as to wake up the vehicle-mounted device; the method comprises the following steps:
and S21, the vehicle-mounted equipment analyzes the received network awakening data packet after TCP/IP packaging to obtain an analyzed network awakening data packet.
And S22, the vehicle-mounted equipment processes the analyzed network awakening data packet according to a preset access control list rule, and determines whether to trigger the interruption of the vehicle-mounted equipment according to a processing result so as to awaken the vehicle-mounted equipment.
Specifically, if the processing result shows that the wake-on-lan data packet conforms to the preset access control list rule, the interrupt of the vehicle-mounted device is triggered according to the wake-on-lan data packet to wake up the vehicle-mounted device.
And if the processing result shows that the network awakening data packet does not accord with the preset access control list rule, discarding the network awakening data packet, not triggering the interruption of the vehicle-mounted equipment, and not awakening the vehicle-mounted equipment.
An Access Control List (ACL) is a packet filtering-based Access Control technique that can filter data packets on an interface according to a set rule, allow them to pass or drop. By means of the access control list, the access of the user to the network can be effectively controlled, and therefore the network security is guaranteed to the maximum extent.
The access control list is a set formed by one or more rules, and the rule refers to a judgment statement describing message matching conditions, and the conditions can be a source address, a destination address, a port number and the like of a message. The rules provided by the method are flexible and changeable, the data packet sending mode can be selected and set according to requirements, and the rules of the access control list are suitable for hardware without WOL function.
The access control list is essentially a message filter, the rules are filter elements for filtering, and the device performs message matching based on the rules, can filter out a specific message, and allows or prevents the message from passing through according to the processing policy of the service module applying the ACL.
In this application, the preset access control list rule is pre-configured in the vehicle-mounted device, and the preset access control list rule includes: packet mode, mode mask, and operation.
Wherein, the data packet mode: including the format or message type of the wake-on-lan packet. The access control list ACL supports a wide variety of filtered message types, including: ICMP, TCP, UDP, GRE, IGMP, IP, IPinIP, OSPF.
Mode masking: the pattern mask is in the same format as the IP address and is a 32-bit numeric string that indicates which bits of the IP address are to be examined.
The operation is as follows: the port operator supports port comparison when the protocol type is TCP or UDP, and the supported comparison operations comprise: equal to, greater than, less than, not equal to, or between.
After the rules of the access control list are configured in advance, the vehicle-mounted device reserves a special interrupt GPIO, and when the vehicle-mounted device is in a sleep state, the GPIO can be interrupted and the GPIO pin is pulled high.
When a network awakening data packet with an access control list rule comes in, data in the network awakening data packet firstly triggers the value of a relevant register on the PHY/SWITCH, then the PHY/SHWITCH triggers the GPIO to interrupt and awaken the Linux kernel, and then the Linux kernel reports a Uevent to awaken the whole vehicle-mounted system. And when the vehicle-mounted system is completely awakened, the GPIO interruption is disabled.
Specifically, when the access control list of the present application is in operation, after receiving network data, the IP gateway processor calls the memory, reads packet header information, such as an IP address, of a network wake-up packet, searches the routing table, checks whether the packet header information is in a routing table entry, if the packet header information is in the routing table entry, forwards the packet from a selected interface of the routing table (if the packet header information is not in the routing table entry, discards the packet), and then the data enters the access control list of the interface and is screened according to a rule set by the access control list.
When the access control list screens the network awakening data packet, once the data of the network awakening data packet is matched with a certain access control list rule, other remaining rules in the access control list are skipped, and the network awakening data packet is allowed according to a judgment statement of the matched access control list rule. If the data of the wake-up packet does not match a certain access control list rule, the next rule in the access control list will be used to test the wake-on-lan packet in turn. The matching process continues until the end of the access control list. And if the data of the wake-up data packet does not match with the access control list rule, directly discarding the network wake-up data packet.
Based on the same concept, in an embodiment, as shown in fig. 3, the present application provides an apparatus for network wake-up of a vehicle device, which is applied to a method for network wake-up of a vehicle device according to any of the foregoing embodiments, where the apparatus includes: a receiving module 10 and a wake-up module 20, wherein:
the receiving module 10 is configured to receive a network wake-up data packet sent by an upper computer and used for waking up a vehicle-mounted device;
the wake-up module 20 is configured to process the received network wake-up data packet according to a preset configured access control list rule, and determine whether to trigger an interrupt of the vehicle-mounted device according to a processing result, so as to wake up the vehicle-mounted device.
In this embodiment, a network wake-up (WOL) data packet sent by an upper computer and used for waking up the vehicle-mounted device is received by the receiving module, and the wake-up module processes the received network wake-up data packet according to a preset configured Access Control List (ACL) rule and determines whether to trigger an interrupt of the vehicle-mounted device according to a processing result so as to wake up the vehicle-mounted device. Therefore, the Access Control List (ACL) function can be used for simulating a network wake-up (WOL) function to quickly wake up the vehicle-mounted equipment which enters low-power-consumption modes such as dormancy and the like, the wake-up time of the vehicle-mounted equipment is shortened, the vehicle-mounted equipment can quickly enter a working mode, and the user experience is improved. The method is particularly suitable for vehicle-mounted equipment without WOL function in the field of vehicle-mounted Ethernet, such as TBOX, OBU, ECU or vehicle-mounted router.
It should be noted that the device embodiment and the method embodiment belong to the same concept, and specific implementation processes thereof are described in detail in the method embodiment, and technical features in the method embodiment are correspondingly applicable in the device embodiment, which is not described herein again.
