碩士 === 長庚大學 === 電機工程學系 === 104 === The research is based on Windows platform with Fast Forward MPEG (Moving Picture Experts Group) and VLC (Video Lan Client) package to successfully create video processing system which is compatible with IP Cameras in the market and it can streaming 4 IP cameras image simultaneously. By capturing IP camera screen for image comparison, the differences in the environment will be identified immediately and then send the zoom-in picture to users for environment change confirmation. This research established and verified LoRa WAN (Low Power Wide Area Network) wireless bi-directional transmission control structure which uses LoRaWan Spread Spectrum technology and low energy system for completing long time battery power support and long distance control system. LoRa has only 10.9% of Wifi static current consumption, 13.36% of Wifi receiving current consumption and 37.81% of Wifi transmit current consumption which proves that LoRa WAN outstanding low power consumption ability. LoRa WAN outdoor transmit range is up to 650M and up to 7 floors height in building transmission. This result is better than WiFi transmitting ability in the same envoirnment. To sum up, LoRa WAN has the characteristic on low power consumption and long distance transmission and the technology can be applied to in filed use for wireless communication system.
