Hydrology Information Observation System Based On Internet Of Things

Water resources as the survival of the natural resources, it can not only provide the necessary life support for the human, will also cause significant impact to human. In recent years worldwide flood happened many times. According to statistics, from 1951 to 1990 in our country serious floods per year on average 5.9 times, the death of three or four one thousand, collapsed houses more than 200 rooms. At the same time, the bonded port area in August 2015, Tianjin east sea international logistics co., LTD to store large amounts of dangerous goods cause huge explosion because of violate the rules, to blow of the giant hole filled with waste water in the rain. Because there is no monitoring of the waters, to rescue,and cause great difficulty working safety checks. Therefore, to this kind of man-made or natural disasters uncharted waters which is formed by the timely implementation of effective monitoring is also very necessary.Water regime telemetry system is a kind of monitoring system used in the rivers and lakes water disasters, is closely related to human life and property safety. The existing water regime telemetry system monitoring content mainly includes: water, precipitation, sediment concentration, temperature, flow, evaporation, ice, such as hydrologic data, the water to be measured using the corresponding sensor of real-time data acquisition, monitoring through remote transmission, realize the whole hydrologic real-time analysis and prediction. However,the existing water regime telemetry system in remote site layout usually exist in the following three questions: 1. The rationality of the station network and the prediction model of compatibility has a lot to do, when measured over the waters of the geographical environment and model matching degree is low will seriously affect the rationality of the site location; 2.When you need to set up collection equipment place far away from the shore, due to theobjective geography at the same time, and the impact of natural factors, lead to the required measuring equipment is difficult to set up, and the higher cost of construction and maintenance; 3. The system design of stand density is different, according to our country has built more than stand density in 250-600 square km/station, the control area, the greater the station network is more sparse, the bigger the investment also, difficult to accurately control the specific scope of tested waters.The Internet of things is the third wave of world information industry development, it will be the main mode of processing data in large amounts of information age. Hydrologic information system based on Internet of things will be the key technology of Internet of things is applied to various hydrologic monitoring and prediction, through the sensor technology,RFID technology, the waters to be measured by mobile hydrologic data collection, the arbitrary point position is measured by monitoring ships, the water to be measured in the form of more mobile monitoring. Through remote data acquisition, speaking, reading and writing implement metal label in hydrologic data, then by data transfer, speaking, reading and writing and realize the data collection and transmission, can quickly and timely, to hydrologic data sent to the application layer monitoring center software, so as to realize the further processing of data.This system based on the hierarchical structure of the Internet of things, the overall design is made up of perception layer, network layer and application layer. System’s hardware design mainly includes the perception layer mobile telemetry terminal control chip of the peripheral circuit, reset circuit, signal conditioning circuit, analog-to-digital conversion circuit,serial communication interface circuit, clock circuit and power circuit design. The network layer mainly through remote data acquisition, speaking, reading and writing sent some GPRS network to realize the hydrologic data of the appliance. System application layer in the monitoring center software is on the Eclipse platform using the JAVA language development,in Microsoft SQL server as the database system, a 3 d real-time display, water regime trend curve, report forms, hydrologic forecasting, early warning information release, historical data query, and other functions, can be collected in timely and accurate hydrologic data storage,analysis and processing, to meet user needs.Experiments show that the hydrologic information system based on Internet of thingsthrough the ship-borne mobile node to achieve the more flexible and convenient hydrologic data collection, to further improve the real-time performance, reliability and accuracy of the system, improve the comprehensive function of hydrologic information system, provide various waters of hydrologic monitoring and effective use of the effective support.
