Abstract

The invention provides a vehicle-mounted OBD (On Board Diagnostic) device internally arranged inertia assembly parallel calibration and detection method and a system thereof to achieve rapid calibration and verification of OBD devices in a batch mode. The vehicle-mounted OBD device internally arranged inertia assembly parallel calibration and detection method comprises the following steps of S1 composing a plurality of to-be-calibrated vehicle-mounted OBD devices into a group to be installed on an equipment installation base surface of a calibration test platform, wherein MCU peripherals which are respectively connected with the vehicle-mounted OBD devices and a main MCU which are respectively connected with the MCU peripherals are installed on the base surface; S2 enabling a computer to send out angle position control information to the calibration test platform and control the calibration test platform to rotate; S3 calibrating, calibrating gravitational acceleration data and rotation angular speed data to be state information to be output to the MCU peripherals which are connected with the vehicle-mounted OBD devices during the rotation process of the test platform; S4 enabling the computer to send the information of a position on which the calibration test platform is arranged to the MCU peripherals through the main MCU and the MCU peripherals to perform calibration calculation according to the collected state information which is output by the vehicle-mounted OBD devices and the information of positions at which the vehicle-mounted OBD are arranged.

Description

technical field [0001] The invention relates to a calibration and inspection method and a system thereof, in particular to a parallel calibration and inspection method and a system for the built-in inertial components of a vehicle-mounted OBD device. Background technique [0002] Integrating MEMS accelerometers, gyroscopes, and vehicle-mounted OBD equipment can realize full-range monitoring of the vehicle's motion status, and the measurement data can assist in evaluating the driver's driving behavior and identifying vehicle collisions, greatly expanding the functions of OBD products and improving the performance of drivers. driving experience. The built-in MEMS accelerometer and gyroscope of OBD equipment are collectively referred to as the built-in inertial components of OBD equipment. [0003] In order to realize the analysis of driving behavior, each OBD device must have the ability of instrument standard output, that is, to achieve the output consistency of acceleration...
