Development of Static and Dynamic Online Measurement System for Ground Vehicles

A measurement system for ground vehicles that works wirelessly is developed. The system is tested by a vehicle-like simulation rig that represents the typical state of ground vehicles in a static or dynamic environment. The vehicle-like simulation rig is constructed in the form of a free rotating wheel which is pressed to a static bike wheel that provides torque as it is pedaled. At the radius of the freewheel, a steel plate with strain gage is installed to measure the normal force. As for the shaft, a strain gage is mounted to receive the resulting torque. To measure the speed, the proximity sensor is used. All of the sensors are integrated with the help of Arduino Nano microprocessor, in which the computer acquires the data through a wireless, i.e., Bluetooth, link. Both static and dynamic data retrieval results conclude that the measurement system is very efficient, comfortable, and has the potential to be used as a wireless measurement system on vehicles and many other industrial applications. However, the existence of measurement noise badly needs noise removal. This noise problem will be addressed in our future work.
