Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0055] For the structural block diagram of the second-hand car detection system of the present invention, see figure 1 , the second-hand car detection system is characterized in that, comprising:

[0056] The vehicle body paint surface data analysis module 100 is used to set the number of vehicle body paint surface data collection surfaces according to different models, and each vehicle body paint surface data collection surface is provided with five collection points; determine the vehicle body paint surface defects according to the vehicle body paint surface data ;

[0057] The five collection points include four collection points distributed on the four corners of each vehicle body paint surface data collection surface, and one collection point located in the middle of each vehicle body paint surface data collection surface. The number of vehicle b...

Abstract

The invention relates to a second-hand vehicle detection system, which comprises a vehicle body surface paint data analysis module, a vehicle chassis data analysis module, a vehicle computer data analysis module, an engine cylinder pressure data analysis module, an engine cylinder body analysis module, an engine performance analysis module and a comprehensive evaluation module, wherein the vehicle body surface paint data analysis module is used for setting the number of vehicle body surface paint data acquisition surfaces according to a different vehicle type, and each vehicle body surface paint data acquisition surface is provided with five acquisition points; vehicle body surface paint defects are judged according to the vehicle body surface paint data; and the comprehensive evaluation module is used for evaluating the comprehensive state of the vehicle according to the vehicle body surface paint defects, the vehicle chassis deformation state, the working state of each part of the vehicle, the engine cylinder body state and the engine power performance state. As each vehicle body surface paint data acquisition surface is provided with five acquisition points, the overall vehicle body surface paint detection efficiency is greatly improved, and compared with the phenomenon that four acquisition points are arranged for the original vehicle body surface paint detection, the efficiency is improved by about 30%.

Description

technical field [0001] The invention relates to the technical field of used car evaluation, in particular to a hand car detection system and detection method. Background technique [0002] Nowadays, cars have become an indispensable means of transportation for human beings. According to the data released by the Traffic Management Bureau of the Ministry of Public Security as of 10:26 on February 4, 2015, the number of motor vehicles in my country reached 264 million. The ratio of new car transaction volume to used car transaction volume in the auto market has gradually changed from 3:1 to 3:5. [0003] It can be seen from this that the majority of consumers have gradually begun to accept old cars. The advantage of buying a used car for customers is mainly due to the lower price, but the biggest concern lies in the condition of the car. Most of the existing used car evaluations are manual evaluations, that is, relying on human subjective concepts and experience to judge the e...
