Electric vehicle speed measuring equipment, modified electric vehicle detection and identification system and detection and identification method

Abstract

The invention discloses electric vehicle speed measuring equipment, a modified electric vehicle detection and identification system and a detection and identification method. The speed measuring equipment comprises a V-shaped support structure composed of a power arm and a supporting arm, wherein a wheel supporting piece is installed on the inner side of the V-shaped support structure, and a speed measuring module is installed on one side of the wheel supporting piece. The speed measuring equipment can be used for lifting an electric two-wheeled vehicle and quickly detecting a rotating speed of the rear wheel. The detection and identification system comprises the speed measuring equipment, handheld PDA equipment and a cloud server. The speed measuring equipment is electrically connected with the handheld PDA equipment, the handheld PDA equipment is in communication connection with the cloud server, and vehicle information and vehicle owner information can be sent to the cloud server through the handheld PDA equipment. The detection and identification method comprises the steps of identity information acquisition, license plate identification, frame number identification, vehicle body abnormal modification identification, OBD detection and the like. The electric vehicle speed measuring equipment, the modified electric vehicle detection and identification system and the detection and identification method have relatively strong man-machine interaction function and information interaction capability, and can help managers to quickly and accurately identify illegal modification of electric two-wheeled vehicles under different conditions.

Description

technical field [0001] The invention relates to the field of vehicle management, in particular to an electric vehicle speed measuring device, a refitted electric vehicle detection and identification system and a detection and identification method. Background technique [0002] Illegal modification of electric two-wheelers is not uncommon. For example, takeaway staff modify electric two-wheelers to increase the speed of electric vehicles, and modify scrapped electric vehicles to prolong the service life of electric vehicles. At present, the illegal modification of electric vehicles mainly includes the modification of high-power motors, the removal of speed limiting devices and pedal riding equipment, the removal of vehicle speed notification devices, the installation or modification of batteries, the addition of umbrella stands and hoods, and unauthorized spraying of bodywork, etc. Illegal refitting of electric two-wheeled vehicles poses a major safety hazard, and has become...

AI Technical Summary

Problems solved by technology

Among them, modifications such as the addition of umbrella stands, hoods, and unauthorized spraying of the body can be accurately identified by the naked eye, but for the modification of the internal performance of electric vehicles such as illegal modification of high-power motors, modification of batteries, etc., it is far from enough to rely on experience to judge. Suspected illegally modified electric vehicles need to be sent to designated locations for special testing, which has the problems of cumbersome procedures and a high rate of misjudgment, which seriously delays the time of electric two-wheeled vehicle owners and the efficiency of management personnel
