The vehicle connector 100 is communicatively connected to the vehicle 300, for example, the vehicle 100 may supply power to the vehicle connector 200 through a ControLLer Area Network (CAN) protocol, a K-wire protocol, a J1708 protocol, or a J1850 protocol.

The method for synchronizing the ignition signals provided by the embodiment of the present application is described below with reference to the vehicle remote diagnosis system shown in fig. 1.

Referring to fig. 2, fig. 2 shows a flow for implementing the synchronization method of the ignition signal provided by the embodiment of the present application, and the main execution body of the flow of the present application is the vehicle connector in the system shown in fig. 1. As shown in fig. 2, the method includes:

s201: an OBD connection is established with the vehicle.

Specifically, the vehicle connector establishes communication connection with an On Board Diagnostics (OBD) On the vehicle in a wired or wireless manner, and when the vehicle performs remote diagnosis, the vehicle connector initializes and establishes communication connection with the OBD On the vehicle through a preset protocol.

S202: an ignition signal of the vehicle is acquired.

Specifically, the ignition signal includes a CANBus ignition signal message, and/or an ignition signal level, and/or a supply voltage. For a particular vehicle to be diagnosed, the ignition signal may be one, two, or even three of the three types described above. In the specific ignition signal synchronization process, the ignition signal synchronization can be realized only if one is effective. The ignition signal of the vehicle is output through the OBD pin, and different ignition signals correspond to different output pins.

For example, the CANBus ignition signal message is typically output by the 6PIN and 14PIN PINs of the vehicle, the ignition signal level is typically output by the 1PIN or 8PIN PINs, and the supply voltage is typically output by the 16PIN PINs. In a possible implementation manner, after a vehicle is started, the vehicle connector acquires vehicle state information sent by the vehicle OBD through PINs 1PIN, 6PIN, 8PIN, 14PIN and 16PIN under the condition that vehicle information is unknown, wherein valid vehicle state information is an ignition signal. The valid vehicle state information may be any one of a CANBus ignition signal message, an ignition signal level, a supply voltage, or a combination of any two or three of them.

Specifically, the obtaining of the CANBus ignition signal message specifically includes: the vehicle connector establishes CANBus connection with a vehicle through a CAN protocol, configures CANBus filtering parameters and obtains a CANBus ignition signal message of the vehicle. In a specific implementation manner, after the CANBus connector establishes CANBus connection with the vehicle, the CANBus filter filters the acquired vehicle message, that is, filters out the message which is not encoded according to the CANBus data format, so as to obtain a filtered CANBus message, and determines the CANBus message containing the ignition signal as a CANBus ignition signal message.

Specifically, the acquiring of the ignition signal level specifically includes: the vehicle connector collects the ignition signal level of the vehicle OBD target pin. The vehicle connector can acquire the level of the ignition signal in a logic level acquiring mode, or acquire the level through the analog-digital converter, namely, the analog signal corresponding to the level is converted into the digital signal.

Specifically, acquiring the supply voltage specifically includes: the vehicle connector collects the supply voltage of the vehicle OBD. The power supply voltage of the vehicle OBD is generally output by a 16PIN of the vehicle OBD, that is, by a power supply PIN of the vehicle OBD. The supply voltage may be obtained by collecting a voltage of a power pin of the vehicle OBD.

Since the ignition signal of the vehicle to be diagnosed may be any one of, or a combination of any two of, or a combination of three of the CANBus ignition signal message, the ignition signal level, and the power supply voltage, the corresponding ignition signal acquisition manner may also be any one of, or a combination of any two of, or a combination of three of the above-mentioned acquisition manners. And is not particularly limited herein.

S203: and packaging the ignition signal into a network data packet.

After acquiring the ignition signal of the vehicle, the vehicle connector performs data encapsulation on the ignition signal so as to encapsulate the ignition signal into a network data packet. Specifically, the encapsulation method used for encapsulating the network data packet is related to the transmission protocol used in the subsequent remote communication. For example, if the subsequent transmission is performed by HyperText Transfer Protocol (HTTP), the step encapsulates the ignition signal based on HTTP Protocol. That is, the network packet is embodied in the form of an HTTP packet. The encapsulation process is not specifically limited herein.

In a preferred embodiment, the vehicle connector encapsulates the vehicle status information and the verification data into a network data packet. The check data can be obtained according to the MD5 message digest algorithm or the CRC algorithm, so that the device connector or the diagnostic device can check the check data, thereby improving the security of data transmission.

S204: and sending the network data packet to an equipment connector through remote communication so that the equipment connector analyzes the network data packet to obtain the ignition signal and sends the ignition signal to diagnostic equipment, and then the diagnostic equipment judges whether the ignition signal meets a preset condition or not and completes ignition signal synchronization under the condition of meeting the preset condition.

Specifically, the vehicle connector transmits the network data packet to the equipment connector through remote communication, so that the equipment connector analyzes the network data packet to obtain an ignition signal and transmits the ignition signal to the diagnosis equipment. The diagnosis equipment further judges whether a preset condition is met or not according to the received ignition signal, and completes ignition signal synchronization under the condition that the preset condition is met. The remote communication can be point-to-point P2P communication or server forwarding. The network for remote communication may be a mobile communication network such as 3G, 4G, 5G, etc., and may also be a wide area network, ethernet, etc.

In the above embodiment, the vehicle connector acquires an ignition signal of a vehicle, encapsulates the ignition signal into a network data packet, and sends the network data packet to the device connector through remote communication, and the device connector analyzes the network data packet to obtain the ignition signal and sends the ignition signal to the diagnostic device, and the diagnostic device determines whether the ignition signal meets a preset condition, and if the ignition signal meets the preset condition, completes the ignition signal synchronization, thereby realizing the ignition signal synchronization in the remote diagnosis process.

Referring to fig. 3, fig. 3 shows a flow for implementing the synchronization method of the ignition signal provided in the embodiment of the present application, and a main body of the flow in the embodiment is the device connector in the system shown in fig. 1. As shown in fig. 3, the method includes:

s301: receiving a network data packet sent by a vehicle connector through remote communication, wherein the network data packet is obtained by encapsulating an ignition signal by the vehicle connector, and the ignition signal is obtained from a vehicle by the vehicle connector.

Specifically, the ignition signal includes a CANBus ignition signal message, and/or an ignition signal level, and/or a supply voltage. The vehicle connector acquires the ignition signal of the vehicle through a specific PIN of the vehicle OBD, such as acquiring a CANBus ignition signal message through 6PIN and 14PIN, and/or acquiring the level of the ignition signal through 1PIN or 8PIN, and/or acquiring the power supply voltage through 16 PIN. After acquiring the vehicle ignition signal, the vehicle connector encapsulates the vehicle ignition signal into a network data packet suitable for remote communication transmission, and then sends the network data packet to the equipment connector through remote communication. With regard to the specific manner in which the vehicle connector acquires the vehicle ignition signal, as well as the packaging manner and the remote communication manner, reference may be made to the above specific contents of the method embodiment of the vehicle connector. And will not be described in detail herein.

S302: and analyzing the network data packet to obtain the ignition signal.

And after receiving the network data packet, the equipment connector analyzes the network data packet to obtain an ignition signal in the network data packet. Based on the network data packet encapsulated by the vehicle connector, the ignition signal parsed by the device connector at this time includes a CANBus ignition signal message, and/or an ignition signal level, and/or a supply voltage.

In a preferred implementation manner, the network data packet received by the device connector includes the verification data, the device connector parses the network data packet to obtain the vehicle ignition information and the verification data, verifies the verification data, and if the verification passes, S303 is executed. The specific check rule may perform the check based on the MD5 message digest algorithm, or perform the check according to the CRC algorithm, which is not specifically limited herein.

S303: and sending the ignition signal to a diagnosis device so that the diagnosis device judges whether the ignition signal meets a preset condition or not and completes ignition signal synchronization when the preset condition is met.

After the device connector obtains the vehicle ignition signal through analysis, firstly, whether the ignition signal is one or two or three combinations of a CANBus ignition signal message, an ignition signal level and a power supply voltage is determined, after the type of the ignition signal is determined, a corresponding sending mode of the vehicle ignition signal is further determined according to the type of the ignition signal, and then the vehicle ignition signal is sent to the diagnostic device based on the corresponding sending mode, so that the diagnostic device judges whether the ignition signal meets a preset condition or not, and completes ignition signal synchronization when the preset condition is met.

Specifically, when the ignition signal comprises a CANBus ignition signal message, the device connector sends the CANBus ignition signal message to the diagnostic device via the CANBus network. Further, the device connector configures CANBus terminal resistance parameters to establish a CANBus network, and then sends the CANBus ignition signal message to the diagnostic device through the CANBus network. In a specific implementation manner, the configured CANBus terminal resistance is 60-120 Ω, and specific parameters can be determined according to a specific vehicle type of a vehicle to be diagnosed. After the CANBus terminal resistor is configured, according to CANBus configuration of different vehicle types, a CAN node inside the equipment connector and a CAN node of the diagnostic equipment jointly establish one or more groups of CANBus bus networks, so that CANBus connection with the diagnostic equipment is established, and the CANBus ignition signal message is sent to the diagnostic equipment through the CANBus network.

Specifically, when the ignition signal includes an ignition signal level, the device connector sends the ignition signal level to the diagnostic device by sending the ignition signal level on the target pin. In one particular implementation, the device connector is configured with an analog OBD interface for simulating a vehicle OBD interface, through which an analog OBD connection is established with the diagnostic device, and then the ignition signal level is output through a specific PIN of the interface, such as 1PIN or 8 PIN.

Specifically, when the ignition signal includes a supply voltage, the device connector outputs a supply voltage associated with the supply voltage to the diagnostic device. In one particular implementation, the device connector establishes a communication connection with the diagnostic device and provides power to the diagnostic device. The device connector outputs a supply voltage associated with the supply voltage to the diagnostic device after parsing the network data packet to obtain an ignition signal including the supply voltage. Wherein the power supply voltage associated with the power supply voltage is a power supply voltage that is the same or similar in voltage value to the power supply voltage. For example, if the supply voltage in the ignition signal is 14V, then the supply voltage may be 13.5V-14.5V; if the supply voltage in the ignition signal is 27V, the supply voltage may be 26.5V-27.5V.

Since the ignition signal in the network data packet may be any one of, or any two of, a CANBus ignition signal message, an ignition signal level, and a power supply voltage, or any three of them, the transmission manner in which the device connector transmits the ignition signal to the diagnostic device is any one of, or any two of, or three of the above-mentioned transmission manners, and the specific transmission manner corresponds to the type of the ignition signal analyzed from the network data packet.

In the above embodiment, the device connector obtains the network data packet sent by the vehicle connector through the remote communication, analyzes the network data packet to obtain the ignition signal, and then sends the ignition signal to the diagnostic device, and the diagnostic device determines whether the ignition signal meets a preset condition, and if so, completes the synchronization of the ignition signal, thereby implementing the synchronization of the ignition signal in the remote diagnosis process.

Referring to fig. 4, fig. 4 shows a flow for implementing the synchronization method of the ignition signal provided by the embodiment of the present application, and a main body of the flow of the present application is a diagnostic device in the system shown in fig. 1. As shown in fig. 4, the method includes:

s401: receiving an ignition signal sent by an equipment connector, wherein the ignition signal is obtained by analyzing a network data packet by the equipment connector; the network data packet is derived by a vehicle connector package from an ignition signal acquired from a vehicle and transmitted by the vehicle connector to the device connector by remote communication.

Specifically, the diagnostic device receives an ignition signal sent by the device connector, the ignition signal including a CANBus ignition signal message, and/or an ignition signal level, and/or a supply voltage. The ignition signal is obtained by the device connector parsing a network packet obtained by the vehicle connector package from the ignition signal obtained from the vehicle and sent by the vehicle connector to the device connector by remote communication. For the specific implementation manner of the vehicle connector acquiring the vehicle ignition signal, the encapsulation manner and the remote communication manner, and the specific implementation manner of the device connector analyzing the network data packet and sending the ignition signal, reference may be made to the above embodiment of the ignition signal synchronization method based on the vehicle connector and the embodiment of the ignition signal synchronization method based on the device connector, and details are not repeated here.

S402: and judging whether the ignition signal meets a preset condition, and if so, completing the ignition signal synchronization.

Specifically, when the ignition signal includes a CANBus ignition signal message, the diagnostic device determines whether the CANBus ignition signal message includes ignition information, and if so, determines that a preset condition is met, that is, the vehicle is ignited, and the ignition signal synchronization is completed.

Specifically, when the ignition signal includes an ignition signal level, the diagnostic device judges whether the ignition signal is a high level or a low level, and if the ignition signal is the high level, the vehicle is considered to be ignited, and the ignition signal synchronization is completed; if the level is low, the vehicle is turned off, and signal synchronization is not required at this time.

Specifically, when the ignition signal includes the supply voltage, the diagnostic device determines whether the supply voltage is within a preset voltage range, and if so, the preset condition is met, and the ignition signal synchronization is completed. In one specific implementation, when the supply voltage is higher than 12V or higher than 24V, it is considered that the vehicle is ignited, and the preset condition is satisfied, and the diagnostic device completes the ignition signal synchronization. Specifically, for a passenger vehicle, the flameout voltage is 12V, and when the supply voltage is higher than 12V, for example, 13V or even 14V is reached, the diagnostic device determines that the passenger vehicle is started at ignition, so that the ignition signal synchronization can be completed; for a commercial vehicle, 24V at the cut-off voltage, when the supply voltage is higher than 24V, for example, 25V or even 27V, the diagnostic device determines that the commercial vehicle is in ignition start, so that the ignition signal synchronization can be completed.

In the above embodiment, the diagnostic device receives the ignition signal sent by the device connector, and determines whether the ignition signal meets a preset condition according to specific characteristic parameters of the ignition signal, and if so, completes the synchronization of the ignition signal, thereby implementing the remote synchronization of the ignition signal.

Referring to fig. 5, fig. 5 shows a specific implementation flow of the synchronization method for the ignition signal provided by the embodiment of the present application. As shown in fig. 5, the method includes:
