A system for calculating a distance travelled by a warning device moving towards a required location includes an obtaining module, a first calculating module, a counting module, and a second calculating module. The number of pulses required to turn a motor through one revolution is obtained, and the first calculating module calculates a moving distance of the device per pulse according to the number of pulses and an outer diameter of a wheel. The counting module counts a total pulses issued as the warning device moves from start to finish of a movement. The second calculating module calculates a first moving distance of the warning device according to the total pulses and the distance moved per pulse, also applying rearward image-taking of an object at start and finish of a movement, to confirm calculations. A distance sensing method of the warning device is also provided.
