MEASURING SYSTEM OF BREAKING PERFORMANCE, DATA ACQUISITION APPARATUS USED MEASURING OF BREAKING PERFORMANCE AND DATA ACQUISITION METHOD FOR THE SAME

摘要

A braking capability measurement system, an apparatus and a method for acquiring braking capability measurement data are provided to acquire braking capability measurement data, wirelessly transmit the data to a remotely located notebook computer and process the data by using the notebook computer so as to improve accuracy and reliability of the data and reduce manpower and time required to calibrate braking capability. An apparatus for acquiring braking capability measurement data includes a trigger sensor(101) outputting a trigger signal when a brake pedal is pushed, a velocity and distance sensor(103) for calculating a running velocity and a stopping distance of a moving body from GPS(Global Positioning System) information received from a GPS antenna and the trigger signal received from the trigger sensor, a pedal pressure sensor(102) outputting a signal corresponding to the pressure applied to the brake pedal, a first signal transformer(T1) for transforming the output signal of the pedal pressure sensor, a cRIO unit(104) for acquiring and storing the running velocity and stopping distance of the moving body and information on the pressure applied to the brake pedal, and a wireless modem(105) transferring data under the control of the cRIO unit.
