Abstract
The invention belongs to the automobile diagnosis field and relates to an OBD (on-board diagnostics) interface-based vehicle diagnosis and processing method. The OBD interface-based vehicle diagnosis and processing method includes the following steps that: a, a mobile phone sends query information; b, an OBD box receives the query information, accesses vehicle information through a vehicle OBD interface, detects and acquires the fault information of a vehicle; and c, the OBD box feeds back the fault information of the vehicle to the mobile phone, and the mobile phone displays the fault information. With the OBD (on-board diagnostics) interface-based vehicle diagnosis and processing method of the invention adopted, the vehicle can be detected automatically through the mobile phone without survey and detection of professional technicians required, which enables quickness and convenience; and the fault information can be displayed for a customer more explicitly and concisely through the mobile phone, and therefore, user experience can be improved.
Description
Technical field
The present invention is applicable to vehicle diagnosis field, particularly relates to a kind of vehicle diagnosis processing method based on OBD interface.
Background technology
OBD full name: On Board Diagnostics translates into Chinese and is: OBD " OBD II " is " on Board Diagnositics II ", the abbreviation of i.e. II type onboard diagnostic system.For making motor vehicle emission and the diagnostic standardization of driven nature dependent failure, from the beginning of 1996, all whole new cars sold in the U.S., its diagnostic instruments, malfunction coding must be similar with maintenance step, i.e. meet OBD II procedure stipulation.Along with economic globalization and the international degree of automobile are more and more higher, as driven nature and discharge diagnostic base, OBD II system will obtain implementing the most widely and applying.OBD II program makes automobile failure diagnosis simple and unifies, and maintainer is not required to learn specially the new system of each producer.But by OBD, vehicle trouble being carried out detection to remain a need for judging according to distinctive instrument with maintainer, for the failure problems of vehicle, car owner can not obtain fault message the most clearly.
Summary of the invention
It is an object of the invention to, design and develop a set of app, realize interconnecting with the OBD box on automobile OBD interface by bluetooth, reach to access the function of automobile fault information,
The present invention is achieved in that a kind of vehicle diagnosis processing method based on OBD interface, comprises the following steps:
A. mobile phone sends Query Information；
B.OBD box receives Query Information, by vehicle OBD interface accessing information of vehicles, detects and obtain the fault message of vehicle；
C.OBD box feedback vehicle trouble messages is shown to mobile phone, mobile phone.
As a further improvement on the present invention, should vehicle diagnosis processing method based on OBD interface include:
A1. mobile phone A PP transmission vehicle body information starts or terminates query statement to OBD box；
B1.OBD box judges the query statement of mobile phone；
C1. if starting a query at instruction, OBD box performs inquiry operation, and result is fed back in mobile phone A PP, and OBD returns state to be checked；If end query statement, the most directly terminate inquiry.
As a further improvement on the present invention, communication is carried out by Bluetooth protocol between described mobile phone and OBD box.
As a further improvement on the present invention, it is somebody's turn to do vehicle diagnosis processing method based on OBD interface, it is characterised in that also include:
D. vehicle trouble messages is uploaded mobile network by mobile phone, feeds back to rescue center by data processing centre, and rescue center carries out rescue service according to information of vehicles.
The invention has the beneficial effects as follows: vehicle just can be detected voluntarily by user by mobile phone, it is not necessary to professional and technical personnel reconnoitres detection, convenient and swift, and by cell phone display can be more directly perceived, succinct present fault message to client, improve Consumer's Experience.
Accompanying drawing explanation
Fig. 1 is the information transmission figure of a kind of based on OBD interface the vehicle diagnosis processing method of the present invention；
Fig. 2 is the information flow chart of a kind of based on OBD interface the vehicle diagnosis processing method of the present invention.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, a kind of based on OBD interface the vehicle diagnosis processing method of the present invention, comprise the following steps:
A. mobile phone sends Query Information；
B.OBD box receives Query Information, by vehicle OBD interface accessing information of vehicles, detects and obtain the fault message of vehicle；
C.OBD box feedback vehicle trouble messages is shown to mobile phone, mobile phone.
OBD box receives conversion medium as information, the conversion by OBD box of the vehicle body fault message, feeds back to fault message cell-phone customer terminal, and shows on mobile phone, user can obtain information of vehicles by mobile phone quickly and easily, it is not necessary to adds new equipment again and is used as detecting display device.
As in figure 2 it is shown, be somebody's turn to do vehicle diagnosis processing method based on OBD interface, including:
A1. mobile phone A PP transmission vehicle body information starts or terminates query statement to OBD box；
B1.OBD box judges the query statement of mobile phone；
C1. if starting a query at instruction, OBD box performs inquiry operation, and result is fed back in mobile phone A PP, and OBD returns state to be checked；If end query statement, the most directly terminate inquiry.
Wherein, communication is carried out by Bluetooth protocol between described mobile phone and OBD box.Mobile phone, without installing and the connection software of OBD box, directly passes through existing Bluetooth protocol and is connected with OBD box, make OBD box be more suitable for mobile phone with the use of, improve the range of application of OBD box.
Further, should vehicle diagnosis processing method based on OBD interface also include: vehicle trouble messages is uploaded mobile network by d. mobile phone, feeds back to rescue center by data processing centre, and rescue center carries out rescue service according to information of vehicles.After vehicle trouble messages is sent to mobile phone by OBD box, by the network of mobile phone, information is uploaded to network, if vehicle on the way runs into fault, or when vehicle needs to be dragged to maintenace point maintenance, by fault message is sent to rescue center, the rescue of road or the eliminating of fault can be obtained in time, meet the vehicle maintenance demand of car owner.
Automobile is generally equipped with OBD interface, OBD interface is used uniformly across 16 trapezoidal pin DLC form connectors, the OBD box of the present invention, insert interface, it is possible to accessing and resolve OBD diagnosis data, OBD box is furnished with bluetooth module, can be attached with mobile phone B T, mobile phone is communicated by Bluetooth protocol, obtains data, and app is shown.Realize interconnecting with the OBD box on automobile OBD interface by bluetooth, reach to access the function of automobile fault information, as long as general cellphone subscriber holds OBD box and smart mobile phone, just can quickly and easily detect fault, and cell phone display, generic failure need not the assistance of specialized maintenance personnel and just can process voluntarily, convenient and swift.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert the present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
