DEVICE AND METHOD FOR MONITORING A CHAIN PARAMETER

摘要

Provided is a system for measuring a chain parameter of a moving chain, wherein the chain has a repetitive structure such as a chain link or teeth in a cogged belt. The system includes at least one image sensor positioned and configured to receive light from the moving chain, and a processor functionally associated with the image sensor. The processor is configured to obtain, from a signal stream received from the image sensor, a chain parameter characterizing the chain while the chain moves. An Image Monitoring Unit (IMU) may be assembled proximal the chain of a bicycles or of a spin bike, and a Human Computer Interface (HCI) unit including a display and functionally associated with the IMU, allows a user to view measurement results of a chain parameter and to operate the system. Further provided is a method of measuring a chain parameter of a moving chain.

1. A system for measuring a chain parameter of a moving chain, the chain having repetitive structure, the system comprising
at least one image sensor positioned and configured to receive light from said moving chain, said light being affected by said repetitive structure when said chain moves, and a processor functionally associated with said image sensor, said processor being configured to
receive a signal stream from said image sensor, said signal stream being related to said light received by said image sensor, and further configured toobtain from said signal stream at least one chain parameter characterizing said chain, including a momentary elastic stretching of said repetitive structure of the chain, while said chain moves.
