Design and research for lower computer system of wave buoy based on GPRS communication technology

Abstract

To achieve the bidirectional communication between wave buoy and remote data center,a design of lower computer system is put forward based on the GPRS(general packet radio service) wireless technology.The MCU(micro control unit) is taken as the core of whole system,after the analog voltage signal is collected and packaged automatically after A/D conversion,so the preprocessed signal is sent to the upper computer system.The SIM300 module takes charge of the transmission communication between the upper computer system and the lower computer system.At the same time,commands from upper computer system is used to control and set the mode of current working by the way of interruption.The system analysis shows that this solution possesses of transmission efficiency under the low cost,and a good feasibility and high stability can decrease the professional maintain with a definite practical value.
