Wireless Wake-up The Mobile Wlan Remote Control Collection Positioning System Design And Implementation

This issue introduced a design for a wake-on-wireless, mobile, WLAN, remote control data acquisition and position system. The system is divided into the Base Station control center and Buoy Front acquisition system two parts. To the Buoy Front system, these following characters could be realized: high sample accuracy, wide measure dynamic scope, the primitive data transmission in real time, remote control power on/off buoy system, wake-on-wireless, and save power consume up to 95% in sleep state, etc. The Base Station control center will show the signal wave and frequency spectrum, GPS position signal, battery electric voltage and temperature, degree of humidity. The total function better than domestic and international systematic now, have very extensive and applied foreground.In the buoy system, the embedded pc is the hardware platform, and designs the data acquisition card to work together with embedded PC, to realize the signal and battery voltage sample. In the data acquisition card, a high speed MCU is treated as controlling core, not only responsible for receive to come from the remote control instruction and change A/D, PGA work mode, system power supply work appearance; At the same time, the MCU is responsible for data transformation , and give signal to inform embedded PC get the final data. In the course of design, the main job are these following: (1) realize 12bit A/D convert reaches 200kHz sample rate with 8bit MCU, (2) realize the power of embedded system could be remote wireless control, (3) the PC/104 interface design between the data acquisition card and embedded PC, (4) the anti-jamming design of the data acquisition card, (5) the link method of waterproof connector, (6) the system power board design, (7) programming the control software; And the (1),(2),(3),(5) are also the main difficulty in the whole task. Compared with other similarity products, the systemic smaller volume, wide bandwidth, battery power supply, remote wireless control power's on/off state, quickly work mode switch, lower power consume in sleep state. And the system is very fit for such situation that demand long-distance, high bandwidth, small scaled, battery power supply to monitor and remote control.
