Operation verification of hybrid temperature recorder monitoring system

Abstract

In current HDDs (Hard Disk Drives) production line, the calibration process of burn-in chambers is required an engineer to manually monitor temperatures at the hybrid temperature recorder throughout the period of calibration process. It is a time consuming and inefficient operation, due to a large amount of burn-in chambers used in the production line comparing with a limited number of engineers to handle. To improve the monitoring procedure of current calibration process, a hybrid temperature recorder monitoring system is developed. The system is composed of two subsystems, i.e., a temperature recording subsystem and a monitoring subsystem, interconnected through a wireless network. To verify the accuracy of system operation, the simulation experiment is set up by acquiring an actual data from current calibration process in the production line. The actual data used to verify in the experiment reflects the results of operation found in three cases, i.e., normal operation, loose probe, and broken probe. The experimental results express that the system yields the same outcomes as in the actual operation of current calibration process. Therefore, the hybrid temperature recorder monitoring system can perform the operation accurately and can be deployed into the actual process in the future.
