Description
Summary:碩士 === 國立高雄海洋科技大學 === 微電子工程研究所 === 106 === In recent years, with the rapid development of wireless networks, the use of wireless networks has been seen everywhere in our lives to indeed achieve cost savings, work safety, and improvement of metropolitan and home city appearance. The coverage of wireless signals can be extend through the Wireless Distribution System (WDS) mode setting between access points (AP) connection.. This study explores how to use WDS technology as an image transmission to establish a wireless monitoring and vehicle plate identification system. Through actual testing and analysis, relative to WiFi mode, the improvement of transmission distance, bandwidth and no packet loss can provide the excellent benefit for vehicle plate identification.This study explores how to use two wireless transmitters, camera, lens, computer DVR host, to establish a wireless vehicle plate identification system in the outdoor environment. When a vehicle enters or exits the entrance to the camera, the screen captured image information transmitting to the DVR host 100 meters away basing on the WDS mode setting, and then the recognizedplate data return to access control equipment under the same setting. It is expected that this study will effectively reduce human resources and improve the security of access control.
