Description
One, technical field
The present invention relates to the technical fields of Dissolved Oxygen in Water content detection, are specifically detected in existing fish pond dissolved oxygen
It is improved on the basis of instrument, realizes the real time monitoring function of the automatic cleaning and fish floating head phenomenon of dissolved oxygen sensor probe,
And realize the wireless transmission of data, constitute a kind of Full-automatic dissolved oxygen detection device being not required to human intervention.
Two, background technology
Aquaculture is a kind of breeding, cultivation and production activity for harvesting aquatic animals and plants under artificial control, is the mankind
Obtain the important means of high-quality meat and protein.With the development of modern aquaculture technology, large-scale industrialized aquatic products
The appearance of cultivation and the intensive breeding way such as high density cage culture, to the automation of fishpond water quality monitoring means require also by
Step improves.
For dissolved oxygen as a key index in aquaculture, growth and survival for fish play vital work
With affecting the vital movement of fish.Water body dissolved oxygen content needed for fish normal growth and development is in 4-5mg/L or more.Work as water
When middle dissolved oxygen is less than 2mg/L, fish stop ingesting substantially, and when dissolved oxygen is down to 1mg/L or so, it is existing that fish just will appear floating head
As when dissolved oxygen is further reduced to 0.5mg/L, fish will death by suffocation.The thus dissolved oxygen one in general breeding water body
As should be maintained at 5-8mg/L, it is minimum to be maintained at 3mg/L.It is difficult in the traditional breeding way for being completely dependent on poultry raiser's experience
Accurately to be judged fish pond dissolved oxygen content, when Changes in weather or the overgenerous feelings of organism in water respiration
Under condition, it is susceptible to the too low phenomenon of water body dissolved oxygen content, to influence the growth of fish, fish death is even resulted in, causes
Direct economic loss.
With the development of Modern Sensor Technology, there is polarogram formula dissolved oxygen sensor, the oxygen molecule in water body is through semi-transparent
Film enters in sensor, and using electrochemical principle realize the real-time detection of dissolved oxygen in water.However since aquatic organism cultivates
The structure of matter is complicated in water body, and there are various planktons and algae.Existing dissolved oxygen sensor probe is when by one section
Between use after often grown nonparasitically upon another plant by biology or adhered to by suspended matter in water or silt, these attachments not only result in probe
Measurement accuracy decline, influence accurate judgement of the keeper for water quality, also will increase keeper prune job input.
Thus designing a kind of dissolved oxygen detection device that can be cleaned automatically has extremely strong practical significance.
In addition, when dissolved oxygen content is reduced to warning line in water body, fish will appear floating head phenomenon, such as takes and arranges not in time
It applies, easily causes fish dead.The means that such phenomenon can be handled with application image carry out effective monitoring, economical to avoid occurring
Loss.As a kind of warning tool of auxiliary, image processing techniques can be very good to be fused in existing water quality monitoring system.
Three, invention content
It is an object of the invention to design a kind of wireless fish pond dissolved oxygen detection that sensor probe may be implemented and cleans automatically
Device, and assist, with image processing means, realizing the accurate real-time monitoring of water body dissolved oxygen content and water hypoxia in aquaculture
The function of alarm, and communication and data transmission are wirelessly carried out with host computer.
To achieve the above objectives, the present invention adopts the following technical scheme that：

Eight parts such as head action control module, wireless communication module, camera control module, Bluetooth communication modules, power conversion module
Composition.Above-mentioned module cooperates under the control of main control module, the common function of completing the design.
(2) operation principle of system：Dissolved oxygen probe converts the dissolved oxygen content index in water to 0- by electrochemical process
The voltage signal of 25mV, under fixed temperature, signal magnitude is proportional to the dissolved oxygen content in water.This signal is put through amplifying circuit
Big and analog-to-digital conversion reads in 8051 microcontrollers, is computed, obtains true dissolved oxygen content signal in water.When measuring oxyty<
When 3mg/L, 2 grades of alarm signals, oxyty are generated<When 1mg/L, 1 grade of alarm signal is generated.Dissolved oxygen content signal
With alarm signal host computer is sent to through radio receiving transmitting module.
The cleaning of probe is completed by minisize dc water pump, at daily noon 12, the photosynthesis most strong period into
Row cleaning, in order to avoid influencing the monitoring of water body dissolved oxygen content, Clean after every is set as 24 hours.When cleaning progress, first upwards
Position machine, which is sent, executes purge signal, stops the detection of dissolved oxygen content, then will be popped one's head in by miniature DC motor and be withdrawn from underwater,
And the water in fish pond is extracted using minisize dc water pump, the flow with certain pressure is sprayed, to clean probe attachment.Cleaning
In the process, by miniature DC motor drive, forward and reverse is rotated by 360 ° probe respectively, realizes whole cleaning.When the above action
After the completion, then by motor it drives probe to return in situ, restarts the detection of dissolved oxygen signal.
Consider that economic cost, the shooting of water surface photo realize that the shooting interval of camera is set as 2 small using general camera
When, to prevent dust from polluting camera lens viewfinder is set in the present apparatus before camera lens.Before shooting, MCU sends signal,
It controls direct current generator driving viewfinder to open, fish pond be shot, after the completion of taking pictures, viewfinder is closed, and photo passes through
Bluetooth chip is sent to host computer.
The device will be appreciated that：
(1) the automatic cleaning of dissolved oxygen sensor probe has may be implemented in the design of the present apparatus, by water body environment for sensing
The adverse effect of device is minimized, and reduces the failure rate of dissolved oxygen probe, and alleviates the cleaning amount of related personnel；
(2) present apparatus adds camera function, and image processing techniques may be used and carried out to the floating head phenomenon of fish pond Mesichthyes
Effective monitoring, avoid because sensor fault cannot and alarm due to cause the possibility of economic loss；
(3) it is communicated with host computer using Radio Transmission Technology, has abandoned traditional wired mode, facilitated device and exist
Initial placement in fish pond or position movement can carry out more efficiently monitoring to the overall condition in fish pond.
