System and method for monitoring operation of vehicles
First Claim
1. A passenger bus comprising a system for acquiring data related to structural loading of the passenger bus during operation, the system comprising:
- one or more sensors configured for sensing structural loadings caused by service operation of the passenger bus, and for providing corresponding output signals;
at least one data processor configured for applying an amplitude counting algorithm to count a number of times said output signals exceed specified amplitudes and to generate data representing peak structural loadings caused by the service operation of the passenger bus;
memory usable by the at least one data processor for storing only the generated data representing peak structural loadings.

Abstract
Systems, methods, devices, and computer programming products useful for the gathering and use of data relating to structural loading and other operational use of transit and other vehicles, and their systems. Systems according to the invention can, for example, comprise one or more data acquisition devices such as strain gauges, accelerometers, or other sensors; data processors; memories; and communications systems. Such systems, methods, and programming are useful in a wide variety of ways, including, for example, monitoring the structural status and use of vehicles and their systems, including fatigue other operational analyses; gathering and applying data useful in the maintenance of such vehicles and the routes they travel; monitoring the use/abuse of such vehicles by operators and other individuals; reporting traffic events or anomalies; and routing transit and other vehicles around such events or anomalies. Rainflow, level-crossing and other peak-counting or event-counting algorithms are applied to advantage, such that required data storage is greatly reduced, and life-long monitoring is feasible.
