It is described in detail individually below.

Fig. 1 is referred to, is a kind of schematic flow sheet of data processing method provided in an embodiment of the present invention.As shown in figure 1, Methods described comprises at least：

Step S101, diagnostic device obtain the diagnostic command to Current vehicle；

Wherein, the diagnostic device can include host computer and slave computer；The host computer and the slave computer can lead to Wired or wireless network connected mode (for example, the connected mode such as bluetooth, WLAN Wlan) is crossed to be attached；In addition, The host computer can also obtain the equipment link information of the slave computer by scanning the forms such as Quick Response Code.

Wherein, the host computer can be used for providing the user corresponding function selection interface (for example, on the host computer The functions such as user can be tested the speed to Current vehicle, fault detect), it can be also used for receiving what slave computer transmitted Diagnostic result, the diagnostic result is shown.

Wherein, the host computer, which can include smart mobile phone, PC, tablet personal computer, notebook computer etc., has net The terminal device of network linkage function.

Wherein, the slave computer is used to obtain the instruction that the host computer is sent, and is instructed according to described from car-mounted device Corresponding data message (such as reading data flow, read failure code etc.) is read on (i.e. vehicle-mounted computer).

Step S102, the diagnostic device extracts the diagnostic mode carried in the diagnostic command, and is based on the diagnosis Diagnostic command processing is the first diagnostic command and second opinion order by pattern, and by Dual channel transmission mode transmit to Car-mounted device；

Specifically, the diagnostic device can extract the diagnostic mode carried in the diagnostic command, if the diagnosis mould Formula is reliability diagnostic mode, then the diagnostic command is copied as to the first diagnostic command and second for carrying identical parameters content Diagnostic command, and first diagnostic command and the second opinion order are transferred to vehicle-mounted dress by Dual channel transmission mode Put；Optionally, if the diagnostic mode is efficiency diagnostic mode, the diagnostic command is split as to carry different parameters content The first diagnostic command and second opinion order, and first diagnostic command and second opinion order are communicated by double-channel Mode is transferred to car-mounted device.

Wherein, the diagnostic mode can be set in advance as reliability diagnostic mode, can also be set in advance as efficiency and examine Disconnected pattern.

Optionally, the diagnostic mode can also be that any one in reliability diagnostic mode, efficiency diagnostic mode diagnoses Pattern, i.e., described diagnostic device can automatically select according to Diagnostic parameters type to the diagnostic mode.Such as when user needs Data are write in vehicle-mounted computer (ECU, electronic control unit), i.e., when described Diagnostic parameters type is parameter read-in type, The diagnostic mode can be arranged to reliability diagnostic mode by the diagnostic device, can also be arranged to the diagnostic mode Efficiency diagnostic mode.When the diagnostic mode is reliability diagnostic mode, the correctness of the data of write-in can be verified, to carry The reliability of high data transfer.Optionally, if now, when the diagnostic mode is efficiency diagnostic mode, the diagnostic device can Be transferred to faster in vehicle-mounted computer with the data that will be write in the vehicle-mounted computer faster, with improve from diagnostic device to this The efficiency of transmission of data between vehicle-mounted computer.

Wherein, the double-channel communication mode be primarily referred to as in Communication Layer using double physical connection line to connect Diagnostic device and the car-mounted device are stated, data waiting for transmission (diagnostic command and diagnostic result) are dispersed in into multiple communications believes It is transmitted on road, it is existing so as to further solve to avoid the baud rate in Current vehicle bus from exceeding default max-thresholds Have in technology, the problem of data are unstable under single channel transmission mode, and then the efficiency of transmission of data waiting for transmission can be improved.

Step S103, the car-mounted device is at first diagnostic command and second opinion order that get Reason, simultaneously performance objective order is obtained, generate diagnostic result corresponding with the command object；

If specifically, the diagnostic mode is reliability diagnostic mode, obtained based on reliability diagnostic mode verification Whether first diagnostic command and the content of parameter carried in second opinion order got are consistent, if unanimously, by described in First diagnostic command is defined as the command object after checking treatment, and performs the command object after the checking treatment, generation with Diagnostic result corresponding to the command object；Optionally, if inconsistent, reacquire the diagnostic device transmission first is examined Disconnected order and second opinion order.

For example when the diagnostic mode is reliability diagnostic mode, the car-mounted device can will (first is logical from double-channel Letter channel and the second communication channel) on the first diagnostic command for getting and second opinion order carry out checking treatment, to compare Whether first diagnostic command and the content of parameter carried in second opinion order are consistent, if consistent, then it can continue to hold The row diagnostic command；If inconsistent, then the distortion phenomenon in data transmission procedure can be more accurately detected, so as to carry The reliability of data in high data transmission procedure.For example, before data is transmitted, first diagnostic command and described second is examined Disconnected order can be 1110 forms, but after the transmission of the data, because data there may be distortion during transmission, Therefore, first diagnostic command can be 1110 forms, and the second opinion order can be 1101 forms, now, described Car-mounted device will determine data check failure, that is, determine data distortion in the transmitting procedure of data be present, so can obtain again The first diagnostic command and second opinion order for taking the diagnostic device to be transmitted based on the double-channel communication mode, until described Car-mounted device will determine data check success, therefore, compared to original redundancy check, based on double-channel communication party Formula, the car-mounted device can get two paths of data, and by comparing the content of parameter carried in this two paths of data, then can be effective Improve the reliability of data in data transmission procedure in ground.

Optionally, if the diagnostic mode is efficiency diagnostic mode, will be got based on the efficiency diagnostic mode First diagnostic command and second opinion order are combined, and obtain the command object after combined treatment, and perform described group Command object after conjunction processing, generates diagnostic result corresponding with the command object.

Such as so that user needs to change the parameter value of transmitter as an example, it is now, corresponding with the parameter value for changing the transmitter Modification order (i.e. diagnostic command) be AABB.When the diagnostic mode is efficiency diagnostic mode, the car-mounted device can be with The first diagnostic command (such as AA) corresponding with the modification order and second opinion are got based on the double-channel communication mode Order (BB), because before data is transmitted, diagnostic device is based on the efficiency diagnostic mode in advance by the diagnostic command (AABB) AA and BB two-way diagnostic commands are split as, and this two-way order is respectively distributed to carry out synchronous transfer on two channels, therefore, The data diagnosis device can be made to get the corresponding command object of parameter value with changing the engine faster, i.e., this When, the first diagnostic command got and second opinion order can be combined by the data diagnosis device, be obtained at combination Command object (AABB) after reason, and perform the command object, to change the parameter value of the transmitter, and after the modification generation with Diagnostic result corresponding to the command object (for example the parameter of the engine has been modified to work().

The diagnostic result is returned to described examine by step S104, the car-mounted device by the Dual channel transmission mode Disconnected device；

If specifically, the diagnostic mode is reliability diagnostic mode, the car-mounted device can answer the diagnostic result The first diagnostic result and second opinion result are made as, and is based on the double-channel communication mode by first diagnostic result and institute State second opinion result and return to the diagnostic device；

Wherein, when the diagnostic mode is reliability diagnostic mode, the car-mounted device is carried out to the diagnostic result The mode for replicating and sending refers to the description that the diagnostic device to the diagnostic command replicate simultaneously sending method, here To no longer it be repeated.

Optionally, if the diagnostic mode is efficiency diagnostic mode, the car-mounted device can also be by the diagnostic result Be split as the first diagnostic result and second opinion result, and based on the double-channel communication mode will first diagnostic result with The second opinion result returns to the diagnostic device；

Wherein, when the diagnostic mode is efficiency diagnostic mode, the car-mounted device is torn open to the diagnostic result The mode divided and sent refers to the description that the diagnostic device to the diagnostic command split simultaneously sending method, here will No longer repeated.

Step S105, the diagnostic device are based on the diagnostic mode and carry out data processing to the diagnostic result.

Specifically, the diagnostic device is examined first diagnostic result got and second based on the diagnostic mode Disconnected result is handled, the objective result after being handled, and controls display to show the objective result after the processing；

Wherein, if the diagnostic mode is reliability diagnostic mode, by first diagnostic result got and Two diagnostic results carry out checking treatment, and the objective result after checking treatment is obtained when verifying successfully, and control display to show Show the objective result after the checking treatment.

Such as by taking the speed for obtaining Current vehicle as an example, it is described to examine when the diagnostic mode is reliability diagnostic mode Disconnected device can get velocity amplitude corresponding with the speed of Current vehicle (for example, the velocity amplitude in first diagnostic result Can be CCDD), if the velocity amplitude in the second opinion result that the diagnostic device is got also is CCDD, the diagnosis Device, which can further determine that, to be verified successfully, you can the speed pair using the velocity amplitude in first diagnostic result as Current vehicle The objective result answered, and the velocity amplitude CCDD of Current vehicle is shown over the display.

Wherein, if the diagnostic mode is efficiency diagnostic mode, by first diagnostic result got and second Diagnostic result is combined processing, obtains the objective result after combined treatment, and after controlling display to show the combined treatment Objective result.

Such as by taking the speed for obtaining Current vehicle as an example, when the diagnostic mode is efficiency diagnostic mode, the diagnosis Device can get velocity amplitude corresponding with the speed of Current vehicle (for example, the speed code in first diagnostic result It can be CC to be worth, and the speed code value in the second opinion result is DD), now, the diagnostic device can be further by institute State the first diagnostic result and the second opinion result is combined, to obtain objective result corresponding to the speed of Current vehicle (for example, velocity amplitude corresponding to CCDD codes after combination be 30 kilometers per hour), and shows Current vehicle over the display 30 kilometers of velocity amplitude is per hour.

Further, Fig. 2 is referred to, is the flow chart of another data processing method provided in an embodiment of the present invention, such as Shown in Fig. 2, methods described can include：

Wherein, the parameter read-in type refers to that the parameter diagnosis function that user selects in selection interface belongs to needs pair The function that the parameter of Current vehicle is read out；

Wherein, the diagnostic device can include host computer and slave computer, wherein, to the host computer and the slave computer Description refer to description in embodiment corresponding to above-mentioned Fig. 1 to host computer and slave computer, will no longer be repeated here.

Step S202, if the parameter diagnosis type is parameter read-in type, obtained in default parameter configuration table First parameter bag, and the first parameter bag is added in the diagnostic command of the Current vehicle；

Wherein, diagnostic mode corresponding with the parameter read-in type and diagnosing protocol are included in the first parameter bag.

Wherein, the parameter configuration table includes baud rate, diagnosing protocol, pin and the diagnostic mode of data transfer, examined The parameters such as disconnected parameter type；

Wherein, the diagnosing protocol can be keyword communication protocol (KWP2000) or controller LAN based on K lines (CAN) the keyword communication protocol of bus, in order to which the diagnostic device and the car-mounted device can be based on the diagnosing protocol Carry out the transmission of data.

Wherein, Controller Area Network BUS (CAN, Controller Area Network) is a kind of for applying in real time Serial communication protocol bus, it can carry out transmission signal using twisted-pair feeder, be in the world most widely used fieldbus it One.The characteristic of CAN protocol can include the serial data communication of integrality, provide real-time support, transmission rate be up to 1Mb/s, There is addressing and the error detecing capability of 11 simultaneously.

Wherein, the diagnostic mode can be reliability diagnostic mode, or efficiency diagnostic mode.

For example when user needs to change the numerical value of Current vehicle transmitter, the diagnostic device can select according to user The function that selection is modified to the numerical value of transmitter in interface is selected, i.e., now, the diagnostic device may recognize that the parameter Diagnostic-type is parameter read-in type, and can further be found and the ginseng in the parameter configuration table with changing the engine numerical value Parameters corresponding to number write-in type.Specifically, can be provided in an embodiment of the present invention a kind of first with further reference to table 1 The statistical form of parameter bag.
