The data analysis device analyses the vehicle diagnosis information (including vehicle information, data stream and fault code) and timely sending the information to the server. A server installation system data base and a data buffer are used for storing the up-to-date vehicle diagnosis information and sending the information to each open client side.
Description
Technical Field
The utility model relates to an automobile signal collection system especially relates to a remote acquisition device of automobile fault diagnosis data.
Background
When the modern automobile repair professional process demonstration course teaching and simulated troubleshooting training are carried out, in the training process of the fault diagnosis skill of the electric control engine, the inherent microscopic phenomenon of the automobile needs to be analyzed and recognized, namely, a fault state needs to be simulated on the practical training automobile, and the fault is positioned and analyzed according to various detected data. Such a process of change is often not observable in the field. Since the setting of the fault is not known in advance, it is not possible to determine different detection contents from different representations to perform the necessary logical analysis and judgment to finally determine the correct fault location. Therefore, the existing training process is difficult to obtain real-time diagnosis data correctly, needs repeated on-site training, has higher training cost and poorer training effect, cannot be shared and repeatedly exercised by all students, and is not beneficial to the development of the standardized skill habits of the students.
Disclosure of Invention
The utility model provides a car fault diagnosis data acquisition device can correctly obtain real-time diagnostic data, gathers and transmit the remote server to this data in time on, supplies all students to share and practise repeatedly.
The technical scheme of the utility model is that: a kind of car trouble diagnoses the data pick device, the said pick device includes a data analysis apparatus, the said data analysis apparatus connects OBD interface of the car through the K bus, and the said data analysis apparatus still further connects a remote server; wherein,
the data analysis equipment comprises a K bus protocol analysis chip and a microprocessor, wherein the input end of the K bus protocol analysis chip is connected with a K bus, the output end of the K bus protocol analysis chip is connected with the input end of the microprocessor, and the output end of the microprocessor is connected with the remote server.
The utility model has the advantages that: the vehicle diagnosis information (including vehicle information, data stream and fault code) is analyzed by the data analysis equipment and is sent to the server at regular time. The server installs a system database and a data buffer for storing the latest vehicle diagnosis information and transmitting the information to each open client.

fig. 2 is a schematic diagram of a data transmission process in the present invention.
Detailed Description
As shown in fig. 1, the present invention provides a data collecting device for automobile failure diagnosis, which mainly comprises a data analyzing device 10 and a remote server 20, wherein the data analyzing device 10 is connected to the OBD interface of the practical training automobile 30 through a general K bus, and the data analyzing device 10 is connected to the remote server 20 in a wireless or wired manner, and the remote server 20 is further connected to a plurality of clients 40.
Referring to fig. 2, the data analysis device 10 includes a K bus protocol analysis chip 11 and a microprocessor 12, an input end of the K bus protocol analysis chip 11 is connected to the K bus, an output end of the K bus protocol analysis chip 11 is connected to an input end of the Microprocessor (MCU)12, and an output end of the microprocessor 12 is connected to the remote server 20.
The utility model discloses an acquisition device during operation, vehicle OBD interface 13 outwards sends diagnostic data through the K bus, and the data format generally follows the ISO standard, like agreement such as KWP2000, KW 1281. The K bus protocol analysis chip 11 performs K bus specification analysis, analyzes the data into a format recognizable by the microprocessor 12, and transmits the data to the microprocessor 12. After acquiring the data, the microprocessor 12 analyzes the OBD diagnostic protocol, transmits the formatted data stream in a format specified by the format to the remote server 20, buffers the data stream by the remote server 20, and forwards the buffered data stream to each client 40.
Each client 40 can accurately obtain real-time diagnosis data, so that the real-time diagnosis data can be shared by all students and can be repeatedly exercised, and the development of the standardized skill habits of the students is facilitated.
