For the safety problem of heavy duty vehicles running on rampway, a study and design of a safety monitoring system is presented. First we analyze the 923 downhill traffic accidents in Shaanxi to acquire their major causal factors, and confirm the monitor control indexes for the safety monitoring system. Then, the monitoring indicators, signal acquisition module, signal processing module, data communication module, and human-computer interaction intelligent instrument are designed and implemented based on Freescale MC9S12DG128B SCM. Finally, we conduct road experiments for the monitoring system. The results show that the monitoring system for heavy duty vehicles running on rampway could provide an effective way to monitor the security parameters of heavy duty vehicles and alarm, with intellectualization, visualization, security and stability. The safety of heavy duty vehicles when running on rampway is improved.
