- 1. A monitoring system for detecting problems associated with the wheels on vehicle axles comprising one or more sensors located on the vehicle axles adjacent the wheels, a programmable micro processor for receiving and processing the sensor signals to detect an alarm condition and alarm means to alert the driver of a problem with one or more of the wheels wherein said sensors detect heat, noise and/or vibration.
- 20. A networked microcontroller based system for monitoring and recording operating axle faults for a multi axle vehicle where each of the axles on the vehicle has wheels and brakes at both ends of said axles, said system comprising sensors capable of monitoring heat, noise, vibration and shocks associated with said axles, brakes and wheels mounted on each axle, one or more sensor CPUs connected to the sensors monitoring the axles and wheels and brakes, a fault recording CPU connected to said sensor CPUs, said fault recording CPU having a keypad and display for system initialization and a fault warning means.
- 28. A networked microcontroller based system for monitoring and recording operating axle faults for a heavy vehicle cab and trailer hookup, where said cab has at least two cab axles with wheels and brakes at both ends of said cab axles and said trailer has one or more trailer axles with wheels and brakes at both ends of said trailer axles, comprising sensors capable of monitoring heat, noise, vibration and shocks associated with said axles, brakes and wheels mounted on each cab axle and each trailer axle, one or more cab sensor CPUs connected to the sensors monitoring the cab axles and wheels and brakes, one or more trailer sensor CPUs connected to the sensors monitoring the trailer axles and wheels and brakes, a cab fault recording CPU connected to said cab sensor CPUs, a trailer fault recording CPU connected to said trailer sensor CPUs, said cab fault recording CPU having a keypad and display for system initialization and a fault warning and means to permit the cab fault recording CPU and trailer fault recording CPU to communicate with each other.
- 36. A communication system for tractor trailers comprising a cab CPU incorporating a transmitter/receiver and a trailer CPU incorporating a transmitter receiver wherein said cab CPU and said trailer CPU communicate with each other on a multiplex bus.
