Abstract
The invention discloses detection equipment and a detection method for a car fuel/intake/ternary system. The equipment belongs to the field of car repair and maintenance equipment. According to the equipment, an endoscope is used for collecting an image, the carbon deposition situations of parts such as a car piston top, an intake valve, and a throttle valve body can be displayed through a liquid crystal screen, and the image storage and comparison functions can be achieved. The invention adopts the following technical scheme: the endoscope outputs a CVBS (composite video broadcast signal), and the image is displayed through the liquid crystal screen, processed through a video processing chip and transmitted to a 4S shop reception desk through Bluetooth for storing and printing. The equipment is also provided with the liquid crystal screen used for displaying a vehicle-related part standard image so as to enable the vehicle-related part standard image to be compared with a real-time image of the endoscope. The equipment is regularly used for detection, so that the problem of excessively large vehicle fuel consumption or engine damage caused by excessive deposited carbon can be effectively avoided, the problem of repeated maintenance can be also avoided and the equipment has a positive meaning on car maintenance.
Description
Technical field the present invention relates to a kind of vehicle fuel/air inlet/three-part system checkout equipment and detection method thereof, concretely, is a kind of vehicle fuel/air inlet/three-part system checkout equipment of new structure and the implementation method of measuring ability thereof.
Background technology is along with the quick growth of China's economic, and automobile pollution increases in the annual speed with millions of of China.Automobile in use; be subjected to various condition restriction, the inadequate situation of oil inflame occur through regular meeting, and then can produce carbon distribution at positions such as piston top, inlet valve and throttle bodies; can increase oil consumption after carbon distribution is too much, also may cause often flame-out even damage engine of vehicle.
There is not special equipment to check the carbon distribution situation of region of interest on the market now.Can only be used as basis for estimation according to mileage or time during vehicle maintenance carries out region of interest to vehicle and cleans decarbonizing.4S can not provide the testing result that makes the client convince before standing in and maintaining car to the car owner, has increased car owner's distrust.The present invention can allow the car owner see the carbon distribution situation of the current fuel oil/air inlet of its vehicle/three-part system, can see the picture of the fuel oil/air inlet/three-part system of no carbon distribution again, can also give the client with the reporting printing of band contrast picture, that can in time maintain vehicle, can increase the mutual trust at car owner and 4S station again.
Summary of the invention the present invention aims to provide the implementation method of a kind of vehicle fuel/air inlet/three-part system checkout equipment and measuring ability thereof, solves in the past the Motor Maintenance condition judgment only with time, mileage, no visual inspection result's situation.
The technical scheme that the present invention takes is as follows:
A kind of vehicle fuel/air inlet/three-part system checkout equipment, comprise endoscope assembly, 12 cun LCD, endoscope output CVBS signal to 12 cun liquid crystal, can intuitively must see the image that endoscope is gathered by 12 cun liquid crystal, the image of endoscope collection can be realized printing by user software by transferring to foreground, 4S station by bluetooth module behind the equipment capturing pictures; Equipment comprises 7 cun liquid crystal displays of 1 band touch function, can transfer the normal pictures of fuel oil/air inlet/three-part system of storing in the equipment by the operation touch-screen; By the contrast standard picture, can see endoscope gather the image region of interest carbon distribution what; Equipment comprises the GPRS module, can transmit image to equipment by GPRS, gives renewal of the equipment or adds normal pictures.
Adopt the S3C2440ARM master chip on the device line plate, operating system is WindowsCE5.0,7 cun liquid crystal displays of band touch-screen recited above link to each other with touch-screen control interface and the liquid crystal control interface of S3C2440 respectively by 4Pin FPC and 40Pin FPC line;
The video image that described endoscope is gathered behind video conversion chip 7113, is converted to digital signal and links to each other with S3C2440, and S3C2440 realizes the extracting of image by IIC interface control 7113.
Described bluetooth module, as linking to each other with the USBHost mouth of S3C2440 by USB interface from equipment, when operating system compiles, add the assembly relevant with Bluetooth, should search, match functions such as connection, image transmission with what call relevant api function realization bluetooth in the program.
Described GPRS module links to each other with S3C2440 by serial ports, writes application program and carries out port arrangement by S3C2440 transmission serial data to the GPRS module, and the image data that GPRS receives is handled in data communication etc.
A kind of vehicle fuel/air inlet/three-part system checkout equipment and detection method thereof is characterized in that may further comprise the steps:
After a, the device power, run application automatically behind the os starting, after the application program operation, the backstage is initiated GPRS and is connected, and whether have new normal pictures, the equipment that then downloads to is automatically arranged if searching.
After b, the application program operation, enter vehicle and select the interface, behind selection vehicle brand, vehicle, year money, the interface that the choice criteria picture occurs, can select the normal pictures of different parts according to different detection positions, as detecting fuel system, then select the normal pictures on piston top; Detect gas handling system and then select the normal pictures of throttle body, select to demonstrate on back 7 cun liquid crystal displays the normal pictures of relevant position.
C, endoscope is put into the coherent detection position, then the region of interest image carbon distribution situation that can be shown to vehicle region of interest on 12 cun liquid crystal displays with do not have the normal pictures of carbon distribution to be presented at respectively on 2 liquid crystal displays, the carbon distribution situation comes into plain view.
" transmission picture " button on d, 7 cun liquid crystal displays of click, system can initiatively carry out Bluetooth pairing and connect, picture is transferred to the computing machine of foreground, 4S station band pairing bluetooth equipment, by the management software on the operation computing machine, can print easily and detect picture and normal pictures, form examining report;
Good effect of the present invention is:
(1) can realize the detection of position carbon distribution situations such as piston of automobile top, inlet valve, throttle body, testing result can be presented on the liquid crystal display intuitively, also can form reporting printing and file.
(2) avoided can only passing through vehicle driving mileage in the past, running time comes the drawback of subjective judgement carbon distribution situation.Namely avoid repeating maintenance, avoided carbon distribution too much not maintain the infringement that vehicle is caused again.
