Abstract
The averaged temperature has risen sharply due to the green house effect, and this makes the bird conservation become more difficult to realize. It takes a long period of time to monitor the ecology of bird, to determine an appropriate protection strategy. Nowadays, the investigation of bird behavior is generally done through personal observation in Taiwan, but it costs too much manpower and money. Nor is it possible to provide long-term monitoring data. Thus, we should develop some automatic observation methods to monitor birds instead of using manual methods Automatic observation methods, such as video recording or voice recording, are popular in Taiwan. The recording devices are placed in a wild field for several days and are retrieved after they finish the recording mission. Such a recording method can provide a more complete picture of bird ecology, because they can work continuously. However, researchers still can’t acquire data in real time, and some of valuable data may be lost.
In this research, we propose a wireless real-time surveillance system to monitor the ecology of wildlife that can make the in-situ situation be captured immediately. Power sources are usually constrained when monitoring wild areas. Thus, in this paper, we have developed a low power-consumped image transmission system by integrating a MSP430 microcontroller, a FPGA circuit, a solar powered battery, a digital camera, and a GPRS (General Packet Radio Service) modem. In order to make a monitoring system suitable for the circumstances of wild islands, the proposed system is designed with a packet transmitting strategy capable of enhancing pixel validity while effectively decreasing power consumption. Practically, the proposed system is deployed on a wild island in Taiwan near the East China Sea, where is a habitat for migrant seabirds. The experimental results show that the system design is feasible to ecological monitoring and able to effectively maintain the completeness of images with energy efficiency.
