Abstract: This paper proposes a hazardous environment monitoring and control for monitoring information concerning safety and security, utilizing Wireless Sensor Network (WSN) technology. The proposed hazardous environment monitoring and control collects industrial environmental safety and security information from both inside and outside industry environment through WSN-based sensors, collects image information through vision system, and collects location information through wireless radio modules. This collected information is converted into a database through the Virtual Environment Monitoring Server consisting of a sensor manager, image information manager and wireless radio manager. The sensor manager manages information collected from the WSN sensors, the image information manager manages image information collected from vision system and the wireless radio manager processes the location information of the hazardous environment. In addition, a power supply based on solar cell and battery back-up is implemented with the central control unit so that it could also be used in environments with insufficient power infrastructure. Immediately after the occurrence of accident, the Accident Data Recorder (ADR) automatically logs the wireless sensors and vision system data for the legal verification and judicial purpose. This data can be used as a First Information Report (FIR) for accident damage investigation and estimation. And it could be expected that the usage of such a system could contribute to increasing safety and security.
