Abstract
The invention relates to a vehicle failure remote diagnostic method based on in-vehicle information terminal equipment, and belongs to the field of in-vehicle information failure diagnosis. The method comprises the following steps of: firstly, matching Bluetooth equipment and matching a tested vehicle: matching a Bluetooth module of an in-vehicle information terminal with a detection module after ELM327 Bluetooth detection equipment is connected with the tested vehicle, searching the tested vehicle after correct connection of the equipment, and selecting a responding vehicle model and matching the responding vehicle model with the tested vehicle; secondly, starting a detection program of the vehicle after successful matching, detecting one by one according to a serial number sequence of vehicle failure codes, and sending detection data to a center; and finally, performing processed data analysis by a central computer after the central computer receives the data, and sending a warning message to prompt a vehicle owner by the central computer if failure exists. By the method, the failure condition of the vehicle is remotely detected by a management center, and the state information of the vehicle is fed back to a user in real time.
Description
Technical field
This method relates to a kind of vehicle fault remote diagnostic method based on board information terminal equipment, belongs to the on-vehicle information fault diagnosis field.
Background technology:
For the method that traditional vehicle trouble detects, mainly exist following several respects not enough:
1, along with the development of China's automobile industry; Vehicle is more and more, and vehicle maintenance is also more and more important with maintenance, and traditional detection method is when vehicle breaks down warning or abnormal conditions; The user must reach automobile the vehicle detection field or the Auto repair shop of specialty; Utilize professional equipment to detect, the testing cost that the car owner not only will cost a lot of money, the plenty of time that also can delay to vehicle.
2, along with the automobile consumption electronic product occurs, present many automobiles have all been installed vehicle-mounted computer, have functions such as amusement, navigation, reverse image and wireless Internet access, do not have vehicle trouble detection and data-transformation facility but do not provide.When vehicle breaks down or during abnormal conditions; Except that automobile itself had some alarms, the car owner can't know the As-Is of vehicle at all exactly, also can't in time car be reached Auto repair shop; If continue to use, can cause serious consequence to vehicle and personal security.
Summary of the invention
Based on above-mentioned situation, the present invention provides a kind of vehicle fault remote diagnostic method based on board information terminal, through the failure condition of administrative center's remote detection vehicle, and car status information is fed back to the user in real time.
Should may further comprise the steps based on the vehicle fault remote diagnostic method of board information terminal:
The first step: the pairing of bluetooth equipment and the coupling of tested vehicle; With ELM327 bluetooth checkout equipment with after tested vehicle is connected; Board information terminal bluetooth module and detection module pairing, equipment correctly connect the back search by the car vehicle, select the vehicle model of response to match;
Second step: start the vehicle detection program, start the vehicle detection program after mate successfully, detect one by one by the numeric order of vehicle trouble code, and to center transmission detection data;
The 3rd step: data processing, central computer carries out the deal with data analysis after receiving data, and if any fault, central computer sends the alarm message reminding car owner.
Above-mentioned vehicle trouble code shows that on the terminal device platform user learns the failure message of present vehicle accurately through the definition of inquiry failure code.
Beneficial effect of the present invention:
1. adopting the vehicle trouble data acquisition module is to carry out radio communication through bluetooth module and board information terminal, has reduced the cable connection, and module for power supply is provided through the OBDII interface by on-vehicle battery, reduces powered battery.
2. the vehicle trouble code can show on the terminal device platform; The user can be through the definition of inquiry failure code; Can know the failure message of present vehicle exactly, utilize professional equipment that vehicle is detected than traditional vehicle detection field of automobile being reached specialty or Auto repair shop and save time with laborsaving.
3. vehicle trouble detection data are transferred to administrative center through the 3G wireless communication networks of board information terminal equipment; When abnormal conditions occurring; Management centre computer can feed back to the user automatically and with car status information in real time; Prompting and guides the user to use car safety, has reduced vehicle and personal security are caused serious consequence.
Description of drawings
Fig. 1 is the vehicle fault remote diagnostic method process flow diagram that the present invention is based on board information terminal;
Fig. 2 is that the hardware of the inventive method connects block diagram.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further introduction.
As shown in Figure 1; The pairing of bluetooth equipment and the coupling of tested vehicle, with ELM327 bluetooth checkout equipment with after tested vehicle is connected, board information terminal bluetooth module and detection module pairing; Equipment correctly connects the back search by the car vehicle, selects the vehicle model of response to match; Start the vehicle detection program, start the vehicle detection program after mate successfully, detect one by one by the numeric order of vehicle trouble code, and to center transmission detection data; Data processing, central computer carries out the deal with data analysis after receiving data, and if any fault, central computer sends the alarm message reminding car owner.
As shown in Figure 2; The present invention utilizes the vehicle trouble data acquisition module to communicate through Bluetooth wireless transmission and board information terminal; And after the fault-detection data of vehicle gathered, handles and analyze; Utilize the 3G cordless communication network to transfer to administrative center, after Computer Processing, again failure message is fed back to the user in real time.The vehicle trouble data acquisition module is the OBDII interface of standard; Carry out radio communication through bluetooth module and board information terminal; The vehicle trouble data show on the terminal device platform with the form of failure code; The user can know the failure message of present vehicle exactly through the definition of inquiry failure code.Board information terminal utilizes the 3G cordless communication network to communicate by letter with the network management center control computer; Automatically handle, analyze the fault data of vehicle by computing machine; Can realize the remote vehicle real-time detection function, when vehicle trouble, computing machine can pass through note or voice reminder user vehicle trouble situation.
Claims (2)
1. based on the vehicle fault remote diagnostic method of board information terminal, it is characterized in that, may further comprise the steps:
The first step: the pairing of bluetooth equipment and the coupling of tested vehicle; With ELM327 bluetooth checkout equipment with after tested vehicle is connected; Board information terminal bluetooth module and detection module pairing, equipment correctly connect the back search by the car vehicle, select the vehicle model of response to match;
Second step: start the vehicle detection program, start the vehicle detection program after mate successfully, detect one by one by the numeric order of vehicle trouble code, and to center transmission detection data;
The 3rd step: data processing, central computer carries out the deal with data analysis after receiving data, and if any fault, central computer sends the alarm message reminding car owner.
2. the vehicle fault remote diagnostic method based on board information terminal as claimed in claim 1; It is characterized in that; Above-mentioned vehicle trouble code shows that on the terminal device platform user learns the failure message of present vehicle accurately through the definition of inquiry failure code.
