Wireless Data Acquisition

Real time monitoring of slope failures is necessary to maintain the stability of slopes in open cast mines. A 3-level structure of Wireless Data Acquisition System (WDAQ) is developed for real time monitoring of slope deformation and analysis of data. In this paper, a case study is presented in a large opencast coal mine. Deformation in the slopes with slope angles of 49o, 53o, 58o, 64o, 68o and 70o is monitored over old underground workings. The deformation caused due to the external load like movement Heavy Earth Moving Machinery (HEMM). Maximum deformation was 1.57mm for slope angle of 70o. It can be observed that the deformation increased with increased slope angle. This paper also describes that the validation of data based on WDAQ with the conventional method of monitoring as well as numerical modeling. The data obtained using WDAQ is in close to other two methods. The variation is around 11%.

Data Acquisition Module

This paper designs a failure signal remote collection terminal based on engineering mechanical hydraulic system. The terminal takes ATmega16 microcontroller as control core, using BenQ M22A module for GPRS wireless transmission. It overcomes region and time limit of engineering machinery and monitors engineering machinery's running status at any real-time, provides the basis for engineering machinery's breakdown service.
