2Technologies such as O technology (and improvement), SBR technology, CASS, related sewage parameter monitoring and sewage aeration processing procedure supervisory system, need much necessary unattended equipment or monitoring point, because the monitoring point disperses, have a very wide distribution, and be arranged on the more abominable area of environment mostly, transmit data by telephone wire and often get half the result with twice the effort, so be not suitable for building the wire communication network.If adopt the mode in optical fiber or radio station to realize wireless telecommunications, not only the equipment input is costly, and the incompatible needs that move.
The high speed development of infotech has expedited the emergence of many emerging hot research fields, forward position, and wherein wireless sensor network is subjected to showing great attention to of various places academia and industry member with the subject crossing and the application prospects of its height.Wireless sensor network can overcome effectively that existing sewage monitoring method is big to the original eco-environmental impact of water resource, data collection point is few, monitoring range is limited, system price is expensive, equipment volume is big, need in advance shortcoming such as cable laying, being more suitable for sewage to a plurality of zonules, sewage discharge district and carrying out multi-point remote and monitor in real time, is current technical development trend.
Wastewater treatment is the important means and the method for preserving the ecological environment; it not only has the protection water source, purify water, store flood-water for use in a drought, regulate the climate and the irreplaceable ecological functions of multiple uniqueness such as biometric safeguard diversity; also, have huge economical, societal benefits and science, cultureal value for the mankind provide abundant production, living resources.Sewage monitoring based on wireless sensor network can effectively improve sewage monitoring present situation almost out of control.The major technique of present domestic sewage monitoring still adopts artificial fixed point periodic sampling, labor intensive material resources not only, and cost is higher, and can not monitor the variation of sewage discharge gateway flow and water quality in real time.Research and development will greatly promote the level of fwaater resources protection based on the sewage monitoring system of wireless sensor network, improve people's environmental consciousness.Therefore, towards the wireless sensor network of sewage monitoring and the research and development success and the application of monitoring system thereof, will obtain remarkable social benefit.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and effectively improves the sewage aeration monitoring system based on sensor network of wastewater treatment level.
Technical solution of the present utility model is:
A kind of sewage aeration monitoring system based on sensor network, it is characterized in that: comprise being arranged on the on-the-spot wireless sensor unit of monitoring, wireless sensor unit is connected with the CSRC instrument by wireless sensor network, and the CSRC instrument is connected from control regulation valve with the adjusting aeration rate.
Described wireless sensor unit comprises at least one in water quality sensor, liquid level sensor, flow sensor, the dissolved oxygen sensor.
From control regulation valve is electronic rhombus variable valve.
The utility model is rational in infrastructure, and at the technological requirement of sewage disposal process, on-the-spot Industry Control server will adopt sensor Data Fusion, obtain the quantity of information of measured target or environment to greatest extent, and obtains optimum explanation or judgement.Utilize a plurality of sensor resources, by reasonable domination and use to multisensor and observation information thereof, a plurality of sensors in the space or temporal redundancy or complementary information will make up according to certain criterion, explain or describe with the consistance that obtains measurand, make this infosystem obtain the more superior performance of the system that subclass constituted thus than its each ingredient.After receiving a large amount of sensing image data, by data anastomosing algorithm efficiently data are handled, for example, utilized intelligent algorithms such as neural network algorithm, genetic algorithm efficiently to handle, obtain the FEEDBACK CONTROL result through controlling models or expert system then, the behavior of control XM.
The utility model networking flexible configuration is convenient, and the scope of application is extensive, can reduce the dissolved oxygen concentration in the biochemistry pool greatly, optimizes the operation of fan blower, improves the wastewater treatment level.
