| dc.description.abstract | Despite of regulations, major accidents in confined spaces are increasing from time to time. The primary factor like management difficulty, the equipment are expensive, the manufacturer does not coordinate. Conventional confined space management systems are based on work flow management. These systems have little or no information of real-time working status of workers. Therefore, it is very difficult to use these systems as a tool to improve rescue efforts in case of emergency.
We developed a highly integrated technology. For example, active RFID, wireless sensor network emergency, communication technology, and innovated system that provides the real-time location information as well as working status of workers. The system can also detect if the work is falling or lay down on the floor which represents an emergency situation in work places. The worker can also use the portable personal receiver to make an emergency call to the management by pressing the emergency button. A short message will be sent to the manager’s cell phone, the manager can watches live video on site by accessing the 3G video phone number which is also embedded in the short message. This system reduces the time to call foe help when accidents or emergency do occur in confined spaces. And sometimes, one or two minutes differences could mean live or death in confined space accidents.
The achievements of this research include: Important module function limits and information collection, mother board design and layout, software composition, laboratory performance test and adjustment, system integrated, and confined spaces work test on site etc. We tested this system in three confined space: tunnel construction site of Taipei MRT, man-holes of chung-hua telecom, and chemical tank of a LCD manufacture. There field tests showed that the system has successfully transmit emergency calls to the LED receiver at ground level at successful rate of 99%. Results also showed that the manager will receive the short messages at successful rate of 100%. The fields studies confirm that the system does just what we expected.
