Special equipment for measuring size of hard point of chassis of accident vehicle and measuring method

Abstract

The invention discloses special equipment for measuring the size of a hard point of a chassis of an accident vehicle and a measuring method. The special equipment comprises two laser level gauges, andan auxiliary level gauge; a main laser transmitting tube and a laser receiving tube are horizontally arranged on the side surfaces of the level gauges and the auxiliary level gauge; a control line ofthe main laser transmitting tube is connected with a signal output end of the single-chip microcomputer. When special equipment is used for measuring hard points of a chassis of a vehicle body, a traditional direct measurement mode is changed into classified measurement, and when no shielding object exists below a measured point, the center position of the measured point is determined through thetwo level gauges, the distance of the measured point is measured through the laser transmitter, the laser receiver and the single-chip microcomputer, the measurement precision is not affected by theheight of the measured point, the measurement speed is high, and the measurement precision is high. When the lower part of one measured point is shielded, equivalent measurement is realized by addingan auxiliary level gauge and utilizing a rectangular principle, and other parts on the vehicle body do not need to be dismounted, so that the measurement speed and precision are effectively improved.

Description

technical field

[0001] The invention relates to the technical appraisal field of road traffic accidents, in particular to special equipment and a measuring method for measuring the hard point size of the chassis of an accident vehicle. Background technique

[0002] At present, when the traffic police department of the Ministry of Public Security of my country conducts statistical analysis of road traffic accidents, the types of road traffic accidents are classified into frontal collision, rear-end collision, side collision, opposite scraping, same-directional scraping, rolling, overturning, falling, Fire, hitting fixed objects, etc. According to the statistics of the Ministry of Public Security in one year, in all kinds of traffic accidents in our country, the proportion of collision accidents is up to 1%, and the casualties caused by collision accidents account for 1%. Vehicle collision traffic accidents account for more than the corresponding total number of accidents, cas...
