Abstract

A survey of local geotechnical laboratories revealed that data-logging is generally not implemented. Also that the undrained triaxial compression test is part of the bread-and-butter throughput of many laboratories. The general aim in applying an intelligent data-logger to commercial testing is to make the process of testing and results analysis more efficient and more effective.

The development of an intelligent data-logger controlled by a microcomputer is outlined. The main objective in designing this data-logger is "flexibility" to reconfigure the system. Flexibility is achieved through software control. Software design also enables the data to be presented in an individually designed format for inclusion in the final report to the client.

The reasons why the BBC Microcomputer has been selected as the control device for a purpose designed interface unit are outlined. The range of current extensions and potential for future expansion of the BBC Microcomputer will not cause computing power, memory capacity or backup store size to be a limitation for laboratory applications. It should be noted, however, that a more or less standard BBC Microcomputer can be part of a highly cost effective data-logging tool.

The objectives in configuring an intelligent plotter to the triaxial test are to support a technician servicing a number of rigs and the engineer when he analyses the test results. There are considerable potential savings in technician/engineer time. The excellent graphics facilities are used to provide a graphics display to monitor tests as they proceed. The overriding principle that the engineer maintains control in the testing process and results analysis is rigorously maintained.

There are applications to other soils tests suitable for transducer monitoring. Test results are entered through a microcomputer keyboard. Analysis and presentation of data from is subsequently performed by the computer. This data also can be incorporated into a data base containing all the information relating to a ground investigation contract.
