Abstract:
A non-invasive, portable apparatus for measuring, recording and reporting the velocity, deceleration, jerk, and stopping distance of escalators, moving walks, and other conveyor mechanisms, the escalators, moving walks, and other conveyor mechanisms having a braking system, comprising:at least one motion sensor for detecting step, treadboard, pallet, treadway, conveyor mechanism; said at least one motion sensor generating encoded motion measurements as electrical pulses;a trigger mechanism which is used to initiate activation of the braking system of the conveyor mechanism and generates an electric pulse at the precise time of activation;electronic circuitry to receive, coordinate in time, process and buffer data from said at least one motion sensor, and said trigger mechanism, and output data representative thereof; anddata processing means to receive, store and recall the output from said electronic circuitry, and to analyze and present the velocity, deceleration, jerk, and distance traveled data accumulated from said at least one motion sensor and said trigger mechanism.
