Mechanized Bridge’s Monitoring System Based on Embedded Equipment

Abstract

We develop the mechanized bridge’s state monitoring system that is of a testing, isolation and diagnosis device based on embedded ARM microcontroller of LPC2478 for the construction machine. This is shown to be accomplished by the analysis on operating and faulty conditions as well as operating parameters of the construction machine. Consequently, the device can test, store and process the operating condition parameters, for example cooling water temperature, oil temperature, oil pressure, engine rotation speed, oil temperature of torque converter as well as oil level of sump and etc. Furthermore, the real time fault alarm and historical data analysis results can also be realized and illustrated by vivid graphical interface. The embedded ARM microcontroller, which is the core module of the system, manipulates the data acquisition of operating parameters for the construction machine. Application software of ARM chip processes the operating parameters and carries out alarm and control operations under faulty mode of the machine. The failure data can not only be displayed and alarmed synchronously, but also can be stored for further fault analysis. This device can store many different types of operating parameters and has a large storage capacity, so it is applicable to many different types of other construction machines.
