(a), first processing module in the transmitter equipment also is divided by the 3rd dissolved oxygen value of pre-stored in second dissolved oxygen value and the data memory module, to obtain the state fiducial value; And the state fiducial value is sent to digital distance scope through terminal device, show for digital distance scope; To be first processing module carry out analog digital to the dissolved oxygen DO signal that receives, place air to collect dissolved oxygen probe to the 3rd dissolved oxygen value is converted to.
This step (a) preferably is positioned at shown in the foregoing description after the step 101, and carries out simultaneously with step 102.Specifically also can be positioned at shown in the foregoing description one after the step 102.Because sensor device especially dissolved oxygen probe used after a period of time, possibly exist testing result inaccurate.In this scheme; Also be pre-stored with one the 3rd dissolved oxygen value in the data memory module with value as a reference, to be first processing module carry out analog digital to the dissolved oxygen DO signal that receives, place air to collect dissolved oxygen probe to the 3rd dissolved oxygen value is converted to.After the processing of first processing module in the transmitter equipment obtains second dissolved oxygen value, this second dissolved oxygen value and the 3rd dissolved oxygen value are divided by, to obtain the state fiducial value; And this fiducial value sent to digital distance scope through terminal device, show for digital distance scope.The user just can judge the duty of the dissolved oxygen probe in the current sensor device according to the state fiducial value that the current digit display device shows like this.When this state fiducial value equals 1, point out user's this dissolved oxygen probe this moment in proper working order, do not need to proofread and correct.When this state fiducial value less than 1, the prompting user need proofread and correct this dissolved oxygen probe, can certainly determine that according to current second dissolved oxygen value that records needs are not proofreaied and correct by the user.When the needs timing, specifically can comprise the steps (b).
(b) when the state fiducial value less than 1 the time, first processing module is carried out the analog digital conversion to the 4th dissolved oxygen DO signal that dissolved oxygen probe is placed saturated sodium sulfite solution collect, to obtain the 4th dissolved oxygen value according to the analog digital conversion parameter; And the value at zero point of dissolved oxygen DO is updated to the 4th dissolved oxygen value.
Particularly, proofreading and correct dissolved oxygen probe promptly is the value at zero point that will proofread and correct dissolved oxygen DO.At first dissolved oxygen probe is used the clear water wash clean; Place saturated sodium sulfite solution (being oxygen-free water) to gather the dissolved oxygen DO signal of the correspondence of this moment the dissolved oxygen probe that cleans up then; And by first processing module according to the analog digital conversion parameter; The dissolved oxygen DO signal that collects this moment is carried out the analog digital conversion, obtain the 4th dissolved oxygen value.And the value at zero point of the dissolved oxygen DO of pre-stored in the data memory module is updated to the 4th dissolved oxygen value.
Adopt the method for the foregoing description, can be at the state fiducial value less than 1, promptly measure when inaccurate, the value at zero point of dissolved oxygen probe is proofreaied and correct, with effectively to the measuring accuracy of dissolved oxygen content.
On the basis of the foregoing description, another kind preferably scheme is after the foregoing description step 102, can also comprise the steps (c):
Step (c), terminal device are according to the breed information of second dissolved oxygen value, temperature value and pre-stored; From terminal device, obtain corresponding breed help information in the aquaculture knowledge base of pre-stored; And will culture help information and send to digital distance scope, show for digital distance scope.
Particularly; Second processing module of terminal device receives first processing module of transmitter equipment and handles after second dissolved oxygen value and temperature value that obtains; Combine pre-stored to culture information again, from the aquaculture knowledge base of pre-stored, obtain some and culture help information.Alternatively, this breed information can be stored in the memory module in the terminal device with this aquatic products knowledge base, also can be stored in the external memory module of terminal device.The breed information here comprises the aquaculture kind, area at useful family or the like breed information.Can include some in this aquaculture knowledge base and culture some the principle knowledge in the aquatic products field, and some aquaculture experts' empirical knowledge.Can also be pre-stored with some problem descriptions of seeking help of aquaculture user in the memory module.After second processing module receives second dissolved oxygen value and temperature value; Second processing module is according to second dissolved oxygen value and the temperature value information that receive; The breed information that combines pre-stored again; From the aquatic products knowledge base, obtain the principle knowledge of corresponding aquatic products of culturing about the user and some experts' empirical knowledge, can also obtain relevant aquaculture user's the problem of seeking help information.At last the information that gets access to is sent to digital distance scope, check for the user.But the problem of the seeking help information that shows on user's reference number display device; And combination principle sex knowledge and some experts' empirical knowledge can be known the situation of current aquatic products; Can also adopt some effective means according to expert's empirical knowledge, further improve the environment of aquaculture.
Alternatively; After first processing module that second processing module of terminal device receives transmitter equipment is handled second dissolved oxygen value and temperature value that obtains; Also can trigger an instruction; Promptly this second processing module is sent an instruction to digital distance scope, requires digital distance scope to import breed information to user's display requirement user.At this moment, the user can be through the keyboard input breed information that is connected with second processing module of terminal device.And then obtain the principle knowledge of the aquatic products of culturing and some experts' empirical knowledge about the user by second processing module.At last the information that gets access to is sent to digital distance scope, check for the user.
The detection method in the aquaculture waters of present embodiment can provide the breed help information to the user, has further strengthened the intelligent degree that aquaculture detects.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
