Remote NVH problem diganosis using Messaging

NVH (Noish,Vibration and Harshness) data can be used to determine problems with vehicles, engines and machines that have moving parts. Currently, it is typically the user of the equipment that notices any unusual sounds and reports them. Unfortunately, this can be too late in preventing a much larger problem, when earlier diagnosis, would lead to potentially a much cheaper/quicker fix. NVH diagnostic equipment is typically used when a problem is identified, yet the source is unknown. The data is collected and compared with previous information to determine where the likely cause of the problem can be found.

    The solution is to periodically or continuously send NVH data to a central server using messaging software. The server can then store and compare this data with previously recorded data, either of the same machine or a similar model. Either problems can be determined at a much earlier stage than normal or when a problem has occured, the data recorded, examined and used later as a benchmark for future machines. By identifying the problem earlier, the possibility of the machine breaking down is reduced and/or the cost of repair decreased.

    The advantage of using messaging is that the data can be sent asychonously from the machine. Not only can this reduce network costs (e.g by sending at off-peak times) but also provides ease of scalability, robustness and flexibility. The amount of data sent can be minimized even furt...
