Abstract
Currently, the HDDs (Hard Disk Drives) from a production line have to pass an operation test in a burn-in chamber. To ensure quality, after an operation period, the burn-in chamber has to be calibrated. The calibration process requires an engineer to manually monitor a temperature at the hybrid temperature recorder connected to the burn-in chamber throughout the entire process. It is a time consuming operation and inefficient process due to a large number of burn-in chambers used in the production line, when comparing with a limited number of engineers. This paper expresses a development of hybrid temperature recorder monitoring system used to improve such the calibration process. There are two main systems involved, i.e., a temperature recording system and a monitoring system. However, the monitoring system is mainly focused in this paper. Also, an object-oriented analysis and design methodology (OOADM) is applied in the development process. The monitoring system interconnects the hybrid temperature recorder through a wireless network to receive the temperatures captured from sensors inside the burn-in chamber. Then, the temperature data is processed and displayed at the central server of system in the engineering office. This could allow the engineer to centrally monitor all hybrid temperature recorders used in the calibration process of burn-in chamber in real-time. The monitoring system can display the alarm signal when the errors occur during the calibration process and sent it to the engineer for alerting as well. Furthermore, the temperature data can be stored in a database at the central server for future reference. ©ICROS.
