This article advances a new method through analyzing the braking system of the mine hoist and the available testing methods of parameters. This method can be used to test the parameters of braking system by means of turning off power, applying the brake, detecting the distance and the hodograph of run after it, and basing on the effect of applying the brake. The parameters can be tested and displayed by using the system consisting of PC and TMS320F240 DSP produced by TI company.
