Description
Technical field
The invention belongs to automobile detection field, more particularly to a kind of method for detecting vehicle based on smart mobile phone built-in sensors.
Background technology
Auto repair and maintenance have been the daily items for facing of car owner, car owner needs vehicle condition to grasp, existing market is supplied to car owner's use to facilitate succinct detection method simultaneously few, at present the function of smart mobile phone is stronger and stronger, and built-in many sensor cameras, gravity sensor, acceleration transducer, light sensor, microphone, the quickening of smart mobile phone arithmetic speed and network speed is accelerated, the application of intelligence software, mobile phone is set to realize many functions, current phone is quite popularized, car owner everybody have mobile phone, therefore based on a kind of detection method for vehicles of embedded in mobile phone sensor exploitation, car owner can be in time allowed to understand the healthy running status of vehicle, vehicle maintenance maintenance is carried out in time, ensure the health operation of vehicle.
Although existing market has the detection method being connected with OBD diagnosis interfaces by mobile phone, it is adapted to detection of the maintenance technician to electronic control system and exhaust system, he has disadvantages that being not suitable for car owner uses, and one is that additionally dress hardware OBD diagnoses joint on automobile to needs peace.Two be he can only electronics exhaust system fault diagnosis, for many failures of mechanical abnormal sound cannot judge, three vehicle failure indicator lamps are lighted and have played a part of to point out car owner, and four is that the data that OBD is provided are to provide the car owner of specialized maintenance personnel and are difficult to understand.
Therefore need invention a kind of without hardware is installed, car owner is easy to operation, it is possible to the method for detecting vehicle and the whether faulty hidden danger of interpretation vehicle whenever and wherever possible.
The content of the invention
The purpose of the present invention is for the problems referred to above, a kind of method for detecting vehicle based on smart mobile phone built-in sensors is provided, car owner is by downloading APP, calling mobile phone built-in sensors, in enging cabin and drive indoor at a high speed in idling middling speed in engine, and vehicle surveys abnormal sound intensity DB decibel data and vibration frequency during engine traveling, and by abnormal sound data upload link and access cloud server, and reach a conclusion with server database contrast, and testing result is fed back to into client, so as to realize that car owner grasps at any time vehicle operation health condition, and testing result is stored in into cloud server, and can forward and share analysis testing result, opportunity is maintained in the grasp of science in time,
To realize above-mentioned purpose, the present invention employs the following technical solutions realization：Characterized in that, change method comprising the following steps：
Step 1 downloads APP, and binds vehicle
Step 2, is input into distance travelled
Step 3, calling mobile phone built-in sensors
Step 4, test result is tested and preserved to specified location and egulation rotating speed in enging cabin
Step 5, drives indoor specified location and test result is tested and preserved to egulation rotating speed
Step 6, runs over journey specified location in driver's cabin and test result is tested and preserved in the examination of regulation speed
Step 7, test result uploads cloud server
Step 8, compares with the close mileage database of vehicle
Step 9, this vehicle difference mileage compares
Step 10 judges to feed back the whether faulty hidden danger of vehicle
The APP of the step 1 is the vehicle examination program for needing car owner to download, vehicle is bound including carrying out, input distance travelled, calling mobile phone built-in sensors preserve test result and upload test result and call database to be analyzed and compare test result acquisition feedback information etc.
The binding vehicle of the step 1 is typing with vehicle for information about
The input distance travelled of the step 2, refers to the mileage number shown according to the mileometer on Current vehicle instrument board, by the mileage number typing and uploads the process of cloud server
Embedded in mobile phone sensor described in step 3 refers to microphone, and acceleration transducer, calls sensor for testing abnormal sound intensity dB, and vibration frequency and amplitude,
Specified location and egulation rotating speed are tested in enging cabin described in step 4, after referring to opening engine compartment cover, nominative testing position and regulation engine speed test abnormal sound intensity dB in enging cabin, and vibration frequency and amplitude
Driver's cabin described in step 5 drives indoor specified location and egulation rotating speed test, when being vehicle stationary, is driving indoor specified location, and engine speed test abnormal sound intensity dB, and vibration frequency and amplitude are respectively provided in engine idle, middling speed and high speed
Journey specified location is run in driver's cabin described in step 6 and the examination of regulation speed is surveyed, refer in vehicle traveling process, indoor specified location is being driven, in speed low speed, test when middling speed and high speed respectively provides test car speed abnormal sound intensity dB, and vibration frequency and amplitude
Test result described in step 7 includes abnormal sound intensity dB and vibration frequency and amplitude, and time dependent chart, and the upload cloud server is to upload and store cloud server by test result by the mobile network of mobile phone.Described upload cloud server, is to connect cloud server by mobile phone mobile network itself, and transmits test result,
Same vehicle described in step 8, refers to the vehicle of same brand same model same engine same displacement, and the close mileage number can be to specify the vehicle in certain mileage number range
This vehicle difference mileage described in step 9, refers to data based on the data that car owner's first time vehicle unfaulty conditions is uploaded, and the data for uploading every time compare with basic data, repeatedly upload after data, by data based on comprehensive many secondary datas, as basic data next time
The whether faulty hidden danger of feedback vehicle described in step 10, the Data Comparison result of combining step 8 and step 9, analysis judges that vehicle whether there is potential faults, if vehicle is normal, step 8 is with close mileage abnormal sound intensity dB of vehicle, and vibration frequency and amplitude fluctuation without exception and data of beating, and step 9 this vehicle difference mileage abnormal sound intensity dB, and vibration frequency and amplitude fluctuation without exception and data of beating, if there is fluctuating, excessive explanation automotive performance declines, there is components and parts work bad if explanation automobile occur in data of beating, need further M R, and will determine that result is pushed to car owner's mobile phone.
The invention has the beneficial effects as follows：Using embedded in mobile phone sensor, vehicle can be detected anywhere or anytime, vehicle hidden danger is found in time, ensure vehicle safety operation, and detection data is uploaded at any time, based on data remain in server database, and same money vehicle potential faults are analyzed, and analysis result is fed back in time car owner, remind the timely maintenance vehicles of car owner.
