| Abstract: | In order to solve the problem of transporting data from contaminated sites to service center,general packet radio service（GPRS） was applied in environmental pollution monitor domain,data acquisition module and GPRS module were connected by serial port,so data could transport by wireless.Based on MC37I and STC12C5A56S2,a design of wireless data transmission terminal was introduced.Its scheme and hardware were discussed,The structure of data packet of PPP protocol was analyzed in detail.uIP was used in the project,through transplanting of TCP/IP protocol on microcontroller unit（MCU）,data conmmunication between data transmission terminal and monitoring center was realized.The experimental results show that the speed of data transmission could meet the requirements. |
