Driver training anti-cheating timing system and method

Abstract

The application of the invention provides a driver training anti-cheating timing system and method. The system comprises an OBD plug device, a timing distance-measurement instrument, a data transmission device and a secret key generation device, wherein the OBD plug device comprises an OBD plug, a data receiving device, a data encryption device and a first random access memory; the timing distance-measurement instrument comprises a data decryption device, a data analysis device and a second random access memory. In the application, collected automobile running state data is data generated according to an actual running state of an automobile, so that accuracy of student training information is improved; when an attacker pulls out the OBD plug for trying to fake student training information, a first secret key stored in the first random access memory is automatically destroyed since the first random access memory is in a power-off state, meanwhile, and the generation of the first secret key is depended on an original secret key set by specific people, so that after the OBD plug is pulled out, the attacker cannot obtain the accurate encrypted secret key, therefore, the difficulty in faking student training information is improved.

Description

technical field [0001] The invention relates to the technical field of driver training timing, in particular to a driver training anti-cheating timing system and method. Background technique [0002] Currently, during driver training, it is necessary to record training information such as training hours and training mileage of trainees. In the process of obtaining training information, the chronograph needs to obtain the vehicle speed information first, and then obtain the corresponding trainee training information. [0003] The chronograph log can obtain vehicle speed information by using external speed detection equipment such as GPS locators. However, due to the instability of the vehicle speed signal collected by the GPS locator, the vehicle speed information collected by the chronograph log has a large error, thus The error of the training information of the students is also relatively large. In addition, if external speed detection devices such as GPS locators are tr...

Problems solved by technology

However, since the above-mentioned pulse signal received by the chronograph is a signal that is relatively easy to be forged, it is less difficult for the trainee training information to be forged.
