| dc.description.abstract | Along with the wireless communication technology progress, causes the transmission the frequency width gradually to promote, also urges the use mobile device, the union wireless network remote monitoring control application are more and more many, specially the long-range medical service, the home security ,home nursing, electrical appliances automation monitoring. However, for guarantees the transmission efficiency with to regard the video quality the stability, these systems mostly use the wired network and the wireless local area network platform, less applications combine the mobile phone with wireless communication network technology like GPRS (General Packet Radio Service) with Personal Handy phone System to make the correlation with PHS the application.
In addition, is connected in these remote monitoring in the application [ 1 ], most uses the stationary type to capture image and video, The means remote camera is unable to rotate. Therefore the paper proposed mobile device and network camera CCD (Charge Coupled Device), and the base on the GSM network [ 2 ] [ 3 ] with GPRS (General Packet Radio Service) [ 3 ] and the PHS two kind of wireless communications technologies, does for develops the platform, and really makes a set of wireless remote monitoring system.
The goal lies in the use Tablet PC or PDA (Personal Digital Assistant), after matches has the GPRS function or the PHS system expansion, can easily penetrate the Internet the connection, and dynamic controls the remote network CCD, enables the user to be allowed to achieve the wireless remote monitoring goal in anytime and anywhere.
The actual result showed, we can successfully use the Tablet PC, PDA and the Notebook, separately unifies GPRS, PHS and the Wireless Local Area Network, issues the command using the remote control network CCD to achieve up, down, left, right revolving. In addition, may rest on user’’s demand or the basis existing transmission bandwidth automatic selection feedback three kind of different images analyses center most appropriate image, guarantees the image quality and smoothness. | en_US |
