Development of Internet Based Instrumentation System for Real-Timevisual Monitoring of Volcano

An instrumentation system for visual monitoring of volcano usually has a complex structure, this may make difficulties not only in device procurement but also in terms of maintenance. Building the system in simple structure and low budget is a challenge for researchers in the field of volcanology. Aim of this research is to develop a simple and efficient instrumentation system for real time visual monitoring of volcano based on internet network. In general, the system is built upon three main units, i.e.Sensing Unit (SU), Data Acquisition & Control Unit (DACU), and Network Interface Unit (NIU). The SUis visual sensor module, built using commercial CCTV camera and its electronic driver system. The DACU is control and data logger module, built based on PC's hardware and installed computer software that was developed for special purposes. The NIU is internet network interface (hardware and software), it allowing the users to access the volcano activity that was monitored by real time, from anywhere. We implemented a virtual machine techniques to reduce the hardware on DACU system in order to make it simple and low-cost in budget.
