| Abstract: | Making use of 3G Network advantages,a new remote monitoring system for heat exchange station was designed to achieve signal transmission between local controllers and monitoring center,and to overcome signal transmission insufficiencies in radio transmitter and GPRS-based wireless communication system;considering the demands for audio and video signal encoding and decoding,the dual-core architecture was employed to realize local controllers by using ARM and dedicated multimedia DSP.The results show that this can greatly improve the real-time performance,reliability and flexibility. |
