The Collection and Issuance System of The Hydrographic Information

The hydrographic information system based on GPRS network achieves inquiring of remote information, by collecting the hydrographic data form the measure station and sending it to the mobile terminals. It serves for redeploying water resource and flood prevention. The system uses three tiers: measuring station-information center-mobile terminal, the measure stations use microcontroller technology to collect the data of rain and water level of rivers or reservoirs, and then send to the information center by ultrashort wave. The information center manages the hydrographic data after receiving and sends them to the mobile terminals by GPRS Network. Experiments indicate that the system runs dependable, has good real time performance, and can be widely used and has good future
