| Because of the modern electronic technology, sensor technology, communicationstechnology and computer technology are rapid development. Automatic detection researchbecome into a wide range of popular content. Hydrological monitoring technology from thetraditional manual testing to automated testing changes Automatic detection can not onlytimely and accurate hydrological data transmission, but also save a lot of human physicalresources, protect the personal safety testing.In this paper, the Network of hydrological Station collecting hydrologic data networkinclude: water, water flow, the volume of sediment main hydro testing data. Sensors willhydrological data to control system, the system will be converted to digital signals, analogsignals and stored, WEB system in the form of visits to the final show. Since the systemuses internet transmission of data, we can overcome the monitoring points spread andwide-ranging issues In particular, can reduce copied down the cost of manpower andmaterial data. All hydrological data can be transferred gradually, water testing departmentto ensure timely response to the decision-making. Special modules are designed to monitor,without special guard, greatly improves the automatic monitoring capabilities.LPC2214 is the core processor chip of this system. Real-time OS operating systemand the roof was to achieve a complete Ethernet TCP Design. The system uses an Ethernetinterface chip RTL8019 10M access to the internet, final completion of the functionalnetwork Hydrometric Station. To enhance system reliability, the system also increased theUSB interface. If failure of the network to facilitate the transfer of data backup. OSoperating system was embedded in the software development platform. Most software areadopted the standard ANSI C language, it increase the software portability. |
