VIBRATION MANAGEMENT DEVICE

摘要

In a first aspect, a vibration management device comprises a tool sensor couplable to a tool and a vibration monitor couplable to a tool operator. The tool sensor comprises a vibration sensor arranged to generate a vibration signal indicative of the magnitude of vibration of the tool and an RF transmitter arranged to transmit data indicative of the magnitude of tool vibration. The vibration monitor comprises an RF receiver arranged to receive the data indicative of the magnitude of tool vibration and a processor arranged to update a vibration exposure value as a function of the data indicative of the magnitude of tool vibration and the duration of tool vibration. The processor provides a first output signal to an operator if the vibration exposure value exceeds a first exposure threshold. In a second aspect, a vibration management device comprises a mount couplable to a tool and a vibration monitor couplable to the mount. The vibration monitor is arranged to receive tool identification data stored within the mount when the vibration monitor is coupled to the mount. The tool identification data includes a tool vibration magnitude rating. The vibration monitor comprises a vibration sensor arranged to provide a vibration signal indicating whether vibration of the vibration monitor exceeds a first magnitude threshold indicating that the tool is in use. The vibration monitor is arranged to update a vibration exposure value as a function of the tool vibration magnitude rating received from the mount and the duration for which the vibration signal exceeds the first magnitude threshold. The vibration monitor provides a first output signal to an operator if the vibration exposure value exceeds a first exposure threshold. The vibration monitor comprises a first socket and the mount comprises a corresponding second socket arranged such that when the vibration monitor is coupled to the mount the first and second sockets are coupled together such that data may be transmitted between the vibration monitor and the mount.
