The system can be used for long-term observation of underwater physical, chemical and biological parameters in the field of scientific investigation, can be used for environmental monitoring and pollution warning of riverways and coastal waters and forecasting of disasters such as flood, tsunami and red tide, and has the advantages of low equipment cost, low communication cost, capability of achieving long-term continuous use and avoiding data to be tampered, high automation degree, no secondary pollution and the like.
Description
Technical field
The utility model belongs to the underwater monitoring field, is specifically related to a kind of real-time hydrologic monitoring transmission system based on radio sensing network.
Background technology
Follow the swift and violent raising of rapid development of economy, industrialization degree, for life brings many whiles easily, sewage and gas discharging have brought negative effect to environment.Particularly inland river and coastal waters because take off nearer, influenced the most serious, and the pollution of water environment and atmospheric environment exerts an influence to the world's ecosystems and weather system in century-old on will be tens of in future.In addition, the natural calamity in inland river and coastal waters is threatening littoral production and life at any time.
At present, the detection means for underwater environment information mainly comprises: 1) satellite remote sensing; 2) radar monitoring; 3) oceanographic research ship; 3) fixed marine monitoring station etc.Except these traditional observation methods, along with the progress of submarine observation network, underwater research vehicle technology, the mankind can press close to the observation data that the seabed obtains high resolution more.Can say the monitoring of Yu Haiyang at the three-dimensional development towards " satellite-land-sea-under water ", and monitoring project also develops towards " diversification ".Yet because human lives, Influence of production are received in river course, coastal waters, time and space is complicated and changeable, only relies on these observation density regular, fixed point to satisfy the demands.To cause even casualties of serious urgent loss for severe contamination event or in time early warning of natural calamity.
Summary of the invention
The utility model has proposed a kind of real-time hydrologic monitoring transmission system based on radio sensing network for the deficiencies in the prior art.
A kind of real-time hydrologic monitoring transmission system based on radio sensing network comprises a plurality of ordinary nodes and maincenter node, and described ordinary node comprises gps antenna, solar energy sailboard, solar panel controller, storage battery, control module, ZigBee wireless communication module, cursory and hawser; Described solar energy sailboard is connected with solar panel controller power source input, the power output end of solar panel controller is connected with the power input of control module, the solar panel controller separately connects a storage battery, control module is connected with ZigBee wireless communication module signal, and described measurement and control unit is provided with a plurality of transducer receiving ports; Described solar energy sailboard is arranged on cursory upper end, solar energy sailboard, solar panel controller, storage battery, measurement and control unit, wireless communication module be arranged on cursory in, cursoryly be fixedly attached to the seabed by hawser.Described maincenter node comprises ordinary node and GPRS module, and wherein on ordinary node, measurement and control unit is connected with the GPRS module by signal.
Beneficial effect: the utility model low cost is low, possess low in energy consumption, integrated level is high, the communication cost is low, can use continuously for a long time, the characteristics such as automaticity is high, data are not played a part in this, non-secondary pollution.

Embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of real-time hydrologic monitoring transmission system based on radio sensing network comprises a plurality of ordinary nodes and maincenter node, and described ordinary node comprises gps antenna, solar energy sailboard, solar panel controller, storage battery, control module, ZigBee wireless communication module, cursory and hawser; Described solar energy sailboard is connected with solar panel controller power source input, the power output end of solar panel controller is connected with the power input of control module, the solar panel controller separately connects a storage battery, control module is connected with ZigBee wireless communication module signal, and described measurement and control unit is provided with a plurality of transducer receiving ports; Described solar energy sailboard is arranged on cursory upper end, solar energy sailboard, solar panel controller, storage battery, measurement and control unit, wireless communication module be arranged on cursory in, cursoryly be fixedly attached to the seabed by hawser.Described maincenter node comprises ordinary node and GPRS module, and wherein on ordinary node, measurement and control unit is connected with the GPRS module by signal.
As shown in Figure 3, a kind of real-time hydrologic monitoring transmission method based on radio sensing network: with the analog signal of input, after processing by the modulate circuit in control module, (filtering, amplification, amplitude limit, level conversion) becomes the signal that is fit to collection.Control module is according to the sampling period image data of determining, after merging with the digital sensor signal of coming in by serial ports, select optimal path to send information after preserving, as send failure according to sending again, select sub-optimal path to send, wait for that the order that sends again carries out the transmission task until return to the next circulation that gathers, sends after success, when can't sending misregistration information and begin the next new cycle, final data sends circulation.Save data before data send sends call instruction or the external output port of node spreads out of or the way extracted in the node obtains this data by terminal.The topological structure of input node periphery is so that node is optimum according to known topological structure calculating, inferior major path is alternative as transmit path.Node location moves, cell voltage is too low when occurring, leak and during the situation of self fault, send warning message.As shown in Figure 4, described transmission warning message method: divide the alarm level of transducer according to the comparing result of measured value and threshold value, and a plurality of transducer alarm level information of recombinating, the alarm level of the different nodes of calculating.Successively send information from maincenter node to land terminal according to priority level.
