In-Vehicle Test Equipment of Construction Machinery Operating Status Based on ARM

Article Preview

Abstract:

This paper deals with the testing, isolating and diagnosis of construction machinery. Subsequently, the analysis of operating status, faulty mode and running parameter is carried out. The equipment implements the detection, processing, storage and alarming of the operating status parameters, such as temperature of cooling system, oil temperature, oil pressure, engine rotation speed, oil temperature of torque converter as well as oil level of sump and etc. Meanwhile, the real time fault alarm and historical data analysis results can also be performed 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 machinery. Application software of ARM chip processes the operating status parameters and accomplishes alarm and control operations under failure pattern of the machine. The failure data can not only be displayed and alarmed synchronously, but also can be stored for further fault analysis. The equipment can record various types of operating parameters, and is applicable to many different types of engineering vehicles.
