Embodiment Construction

[0038] Below, the present application will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, on the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form a new embodiment. .

[0039] Such as Figure 1-2 As shown, it is an application scene diagram of the vehicle data transmission method provided by the embodiment of the present application. The data transmission method is applied to the vehicle equipment, and the vehicle equipment may be an OBD box connected to the OBD interface on the vehicle. When the on-board device sends a diagnostic command to the vehicle ECU, the on-board device is the sending end, and when the on-board device obtains the diagnostic data returned by the vehicle ECU, the on-board device is the receiving end.

Abstract

The invention discloses a vehicle-mounted data transmission method, which is applied to vehicle-mounted equipment and comprises the following steps: acquiring a current to-be-sent data packet and thedata length of the current to-be-sent data packet; judging whether the data length of the current to-be-sent data packet is greater than a preset length or not; if the data length of the current to-be-sent data packet is not greater than the preset length, sending the current to-be-sent data packet to a receiving end; and when the sending is finished, entering a sending finishing state of the current to-be-sent data packet, and obtaining the next to-be-sent data packet by the vehicle-mounted equipment. The invention further discloses the vehicle-mounted equipment. According to the vehicle-mounted data transmission method and the vehicle-mounted equipment provided by the invention, after the current channel calls the sending function to send the current to-be-sent data frame, the sending function is quitted, so that the next channel calls the sending function to send the next data frame, parallel transmission of multiple channels is realized, and the data transmission efficiency is improved.

Description

technical field [0001] The present application relates to the field of data transmission, in particular to a vehicle-mounted data transmission method and vehicle-mounted equipment. Background technique [0002] At present, with the development of electronic control units (Electronic Control Unit, ECU) and big data in automobiles, higher requirements are placed on the transmission of diagnostic data, and multi-channel data communication can save data transmission time. However, existing on-board devices such as On-Board Diagnostic (OBD) can only communicate in a single channel. After sending and receiving a data packet, the next packet of data can be sent, and two packets cannot be sent at the same time. In the transmission of on-board data of more than one road or more, the hardware resources cannot be fully utilized, and the data transmission time is affected. Contents of the invention [0003] In order to overcome the problem that the existing vehicle-mounted equipment ...
