Chet, Ngo Chon (2006) Development of Commercial Vehicle Speed Warning System. Masters thesis, Universiti Putra Malaysia.
The use of commercial road vehicles has grown with the recent rapid economic growth in the world, but reckless speeding of these heavy vehicles has resulted in fatal accidents leading to loss of innocent road users lives. Although it is generally recognized that the majority of the heavy vehicle drivers on the road are law biding citizens, there is, however, a small but highly conspicuous percentage that persist in speeding and operating their vehicles in an unsafe and reckless manner. Due to these reasons, the commercial vehicle speed warning system is designed and developed to monitor the commercial vehicle speed and determine if the vehicle has exceeded the preset speed limit. This warning system consists of two subsystems, the in-vehicle subsystem and the peripheral interface subsystem and both subsystems are designed by using the MC68HC11E9 microcontroller in conjunction with the AxIDE program. The in-vehicle subsystem is fitted into the vehicle for speed monitoring, whereas the peripheral interface subsystem, which is connected to the host computer, allows the proper calibration of the in-vehicle subsystem as well as the data downloading. A toothed wheel is built as the vehicle engine model to test the warning system in the laboratory and the radio frequency serial communication module is used to establish communication link between these subsystems and both subsystems will support the same communication protocol. The basic concepts of in-vehicle speed detection is developed and achieved, and the wireless data setting and retrieving system is designed, which provides control over the in-vehicle subsystem functions.
