Problems solved by technology

However, the connection and installation of external devices is complicated, and the access of external devices is likely to interfere with the circuit structure of the vehicle circuit system itself, and even cause damage to the vehicle circuit system. Signal interference often results in poor quality and incomplete information collected, which cannot guarantee accurate and fast feedback of vehicle driving information

Embodiment 1

[0037] refer to figure 1 , shows a schematic structural diagram of a CAN bus speed sensor in Embodiment 1 of the present invention. In this embodiment, the CAN bus speed sensor may include:

[0038] The CAN bus terminal 102 is used to collect parameter information of the vehicle and send a message carrying the parameter information.

[0039] CAN bus, ControllerAreaNetwork, controller area network bus, is a serial communication protocol bus for real-time applications, which can use twisted-pair wires to transmit signals. In this embodiment, the parameter information of the vehicle can be collected based on the CAN bus through the CAN bus terminal 102. For example, the CAN bus terminal can receive the vehicle body bus signal based on the standard protocol of the CAN bus, wherein the vehicle body bus signal carries the Various parameter information, the parameter information may include but not limited to: vehicle speed signal, wheel speed signal, vehicle body acceleration sign...

Embodiment 3

[0067] Based on the above-mentioned embodiments, this embodiment takes the actual application of the CAN bus speed sensor in vehicles as an example to describe the structure of the CAN bus speed sensor in detail. If there is no contradiction, the CAN bus speed described in this embodiment The sensor can be combined with the CAN bus speed sensor described in the above embodiments. The structure of the CAN bus speed sensor described in this embodiment will be specifically described below.

[0068] refer to image 3 , shows a schematic structural diagram of a CAN bus speed sensor in Embodiment 3 of the present invention. In this embodiment, the CAN bus speed sensor may include: a CAN bus terminal 302, a data transmission chip connected to the vehicle body through the vehicle body OBD II interface, a mobile terminal, a digital signal processor 308, a generalized data acquisition device 310 and a database server 312. Wherein, in this embodiment, the data transmission chip may sp...

Embodiment 4

[0082] Based on the same inventive concept as the above device embodiment. refer to Figure 4 , shows a flow chart of steps of a CAN bus-based data processing method in Embodiment 4 of the present invention. In this embodiment, the CAN bus-based data processing method may include:

[0083] Step 402, obtaining a message carrying parameter information of the vehicle from the CAN bus terminal.

[0084] Step 404, sending the message to the mobile terminal through the data transmission chip.

[0085] In step 406, the mobile terminal parses the message to obtain first data information for indicating vehicle speed and / or engine speed.

[0086] Step 408, loading and displaying the first data information in the terminal interface of the mobile terminal.

[0087] To sum up, according to the data processing method based on the CAN bus speed sensor described in this embodiment, the CAN bus terminal can directly collect the original parameter information from the vehicle without any si...

Abstract

The invention discloses a CAN-bus rotating speed sensor and a data processing method based on a CAN bus. The CAN-bus rotating speed sensor comprises a CAN bus terminal, a data transmission chip, and a mobile terminal. The CAN bus terminal is used for acquiring the parameter information of a vehicle and sending a message carrying the parameter information. The data transmission chip is used for receiving the message sent by the CAN bus terminal and sending the message to the mobile terminal. The mobile terminal is used for receiving the message sent by the data transmission chip, analyzing the acquired message in order to obtain first data information indicative of vehicle running speed and / or engine rotating speed, and displaying the first data information in a terminal interface of the mobile terminal. The CAN-bus rotating speed sensor may accurately and fast feed back running information of the vehicle without any external devices, and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a CAN bus speed sensor and a data processing method based on the CAN bus. Background technique [0002] At present, with the improvement of people's living standards, automobiles have gradually become people's main means of transportation, and vehicles are becoming more and more intelligent. The number of automotive electronic control units and automotive electronic devices continues to increase, and serial buses are used to achieve multiple transmission. It is a reliable and economical way to form an automotive electronic network. At the same time, based on the requirements of safety and reliability, modern automobiles are increasingly considering the use of electronic control systems to replace the original mechanical and hydraulic systems. [0003] When the user uses or detects the vehicle, he needs to know the form information of the vehicle in time, and record it or provid...
