Development of a Wireless Remote Monitoring System Utilizing Multiple Wireless Sensors

摘要

A novel remote monitoring system for all day outdoor observation using multiple wireless sensors and wireless communication (Handy phone and PHS) is proposed. The whole system consists of three parts: (ⅰ) a host station that is a PC (personal computer); (ⅱ) a remote station that contains a camera controlled by a CPU and a power supply (battery attached by solar cell); and (ⅲ) multiple wireless sensors each having its own ID signal. The remote station usually works by an event-driven method based on the wireless sensor signals. Because of this event-driven method, various multi-vision systems are easily configurable. This paper describes the details of the system and evaluates the possibility of the application of the system. Since some of the systems are now actually running in many places, we can consider that the effectiveness of the system is shown by that fact in a practical sense.
