A No-cable Borehole Inclinometer Based on PDA and Bluetooth

Abstract:

This paper introduces a no-cable borehole inclinometer based on PDA and bluetooth, which uses triaxial semiconductor magnetometer and two-axis accelerometer sensor as the measuring element and is suitable for non-magnetic interference borehole. Automatic storage approach is used for measurement data acquisition without cable logging configuration； taking PDA as the core， a measurement software based on Windows Mobile 6.0 is developed; wireless communication between inclinometer and PDA is realized by bluetooth instead of the data cable. The instrument has advantages of high precision， good reliability， light weight， less supporting equipment and easy operation, can greatly reduce the field work intensity with higher efficiency and significantly reduce the configuration costs.
