Abstract Microprocessor reliability in coal mine monitoring applications has become
increasingly important in recent years.This has been true not only for the mining industry,but the computer industry as well.Processor maintenance self-diagnostics have been commonly utilized for microcomputer systems.However,in the case of a microprocessor used in a critical monitor/control environment,small memory and little free processing time limits the use of these diagnostics on a continuous basis.In the past,maintenance diagnostics have been very exhaustive for minicomputer systems and execution time can be quite long.These were primarily used on an infrequent aperiodic basis by a maintenance technician.Normal system diagnostic tests are generally run at time of power up,and the system becomes operational only after successful completion.If diagnostic tests could occur automatically without user interference,such as when the system is not being heavily utilized,it is possible that failures could be found more quickly and without catastrophic system failure.Solutions to these problems are presented as applied to a distributed microprocessor system used for testing mine monitor/control systems.A set of self-test algorithms for an 8085-based microprocessor is presented.Tests are performed on the CPU,ROM,RAM,8251A USART,A/D,and D/A converters,and an 8253A interval timer.These self-test algorithms are not exhauastive but have been found to provide an adequate test of microprocessor validity on power up.Similar tests could and should be used on any underground monitor/control system as a minimum test.
INTRODUCTION
THE HEALTH and safety of underground miners has been greatly affected by the introduction of computer-based monitoring/control systems [1].Therefore,it is the moral obligation of manufacturers of these systems to make their systems as reliable as possible.Likewise,it is the moral obligation of the mine operator to install reliable systems in their mines.Self-testing is one way of offering hardware reliability to a system.In a recent survey,reliability of equipment in the mine environment was cited as being the most influential factor in considering the purchase of a monitoring system [2].
Self-testing is a method of testing a chip or circuit board of chips where the test is performed without the aid of any external equipment or any external software [4].A self-testing algorithm,since it is always in memory,is often called resident diagnostics [10].Much work has been done on system self-testing in the past decade.However,most of the work includes extra hardware on the processor board to implement complete self-testing [4]-[10].
