Referring to fig. 1, the present application provides a maintenance-free and consumable-saving dissolved oxygen monitoring method, and applies the method to a dissolved oxygen monitoring apparatus, the dissolved oxygen monitoring apparatus including: the device comprises a device body 100, a probe track 200 arranged on the device body 100, a fluorescent probe 300 arranged on the probe track 200, a cleaning device 400 arranged on the device body 100 and a controller 500. The shape of the apparatus body 100 may have various forms, for example, may be a hull shape, which includes a power source, a power device, and a steering device, can freely move on the surface of the pond water, and is controlled by the controller 500; the controller 500 comprises a GPS positioning system and a 4G communication module, has the functions of algorithm downloading, track calculation and the like, and has full-automatic control capability; the probe guide rail 200 can lift the fluorescent probe 300 under the control of the controller 500, and the lifting implementation form is not limited; the probe adopts the fluorescent probe 300, the fluorescent probe mainly utilizes dynamic fluorescence quenching of a fluorescent material to realize dissolved oxygen measurement, the fluorescent probe is unlike a chemical dissolved oxygen sensor technology, the luminous dissolved oxygen sensor does not consume oxygen, and no electrolyte or oxygen permeable membrane exists, so that the probe is basically maintenance-free in daily use; the cleaning device 400 may be provided as a water rinsing device or an ultrasonic rinsing device or a bubble cleaning, and the following embodiments will be described taking water rinsing as an example. Because the fluorescent probe can also encounter the problems of dirtying, detection misalignment (such as climate change influence and the like) and the like after being used for a period of time, the technical problem of accurately and low-cost monitoring the dissolved oxygen amount so as to improve the overall culture efficiency of the fish pond becomes a technical problem to be solved.
The following will primarily describe specific steps of a maintenance-free and consumable-free dissolved oxygen monitoring method, it being noted that although a logical sequence is shown in the flow chart, in some cases the steps shown or described may be performed in a different order than that shown or described herein.
Referring to fig. 2, the maintenance-free and consumable-saving dissolved oxygen monitoring method comprises the following steps:
s100, determining and monitoring dissolved oxygen based on a detection value of the fluorescent probe;
s200, determining that the difference value between the monitored dissolved oxygen amount and the preset dissolved oxygen amount is larger than the preset difference value;
s300, acquiring the cleanliness of the fluorescent probe;
s400, determining that the cleanliness is smaller than a first preset cleanliness or the difference of the cleanliness of the two groups of probes is larger than the maximum difference of the first preset cleanliness, and correcting the monitored dissolved oxygen to obtain the actual dissolved oxygen content.
Specifically, in the present embodiment, the dissolved oxygen amount is first monitored by determining based on the detection value of the fluorescent probe; determining that the difference between the monitored dissolved oxygen and the preset dissolved oxygen is larger than the preset difference; then acquiring the cleanliness of the fluorescent probe; finally, determining that the cleanliness is smaller than a first preset cleanliness or the difference between the two groups of probes is larger than the maximum difference of the first preset cleanliness, and correcting the monitored dissolved oxygen to obtain the actual dissolved oxygen content; that is, in the process of monitoring the dissolved oxygen amount, if it is found (judged) that the measured value of the dissolved oxygen amount deviates too much from the preset value, it is judged as being affected by the cleanliness of the fluorescent probe, and therefore, when it is further determined that the cleanliness of the fluorescent probe is smaller than the first preset cleanliness, the measured dissolved oxygen amount is corrected to obtain the actual dissolved oxygen amount.
More specifically, the controller 500 receives the electrical signal input of the fluorescent probe, and obtains the monitoring value of the dissolved oxygen after internal operation processing, the monitoring value can be the monitoring value at a certain moment, or can be the monitoring value at a certain time period (a monitoring curve formed by continuous monitoring values at a plurality of moments), the monitoring value at a certain moment is taken as an example to describe the situation, the preset dissolved oxygen can be independently set or comprehensively considered according to the weather, the power of the oxygen supply machine or the size and the type of different fish shoals, in the embodiment, the preset dissolved oxygen is 4mg/L at 18-5 points, 5mg/L at 5-12 points, and is 6mg/L at 12-18 points, and the preset dissolved oxygen is the optimal oxygen supply configuration of the fish pond culture, so that when the difference between the real-time monitored dissolved oxygen and the preset dissolved oxygen is larger than the preset difference, the risk of the floating head exists, but the problem that the fluorescent probe encounters dirtying, the problem that the detection performance of the fluorescent probe is seriously influenced by the weather, the problem that the water quality is seriously detected, the problem that the water quality is seriously influenced by the fact that the water quality is judged when the water quality is high, the water quality is clean, and the problem is completely measured, and the problem is completely is solved, when the water quality is completely is required to be completely, and the problem is completely, and is completely measured. It can be understood that the lower the cleanliness of the fluorescent probe is, the more inaccurate the monitoring value is, i.e. the smaller the detected value of the detected dissolved oxygen amount is, the greater the possibility of misjudgment and false alarm is.
There are various ways of obtaining the cleanliness of the fluorescent probe 300, such as obtaining by a micro camera device, obtaining by the ascending resistance of the fluorescent probe 300 or obtaining by the driving power judgment of the ascending and descending of the head rail 200, and taking the image capturing as an example, the camera device may be disposed on the water surface or under the water.
Because the areas of the fishponds are different, the shoal amount of the fishpond in different areas or the difference of the microbial environments can influence the dissolved oxygen amount, the dissolved oxygen amount of the fishpond in different directions and different routes is required to be monitored so as to further improve the accuracy and the comprehensiveness of monitoring the dissolved oxygen amount, and further improve the overall cultivation efficiency of the fishpond.
Specifically, referring to fig. 3, before the step of determining the amount of dissolved oxygen to monitor based on the detection value of the fluorescent probe, the method further includes:
s000, acquiring an acquisition route of the dissolved oxygen monitoring equipment;
s010, controlling the equipment main body to run according to the acquisition route and keeping the fluorescent probe under the water surface;
s020, starting the fluorescent probe to detect dissolved oxygen and acquiring a detection value in real time.
Firstly, different routes can be stored in a memory, and the routes can be updated manually at regular intervals, in this embodiment, the processor 500 can acquire one route from the memory at will for dissolved oxygen monitoring, and the processor 500 controls the device main body 100 to travel according to the acquisition route and keeps the fluorescent probe 200 under the water surface; then, starting the fluorescent probe to detect dissolved oxygen and acquiring a detection value in real time; finally, the steps of S100-S400 are performed.
It should be noted that in the time period of a day, the dissolved oxygen amount of one line or a plurality of lines can be selectively monitored, and it can be understood that the more the lines are selected, the wider the range of the dissolved oxygen amount monitoring data is, the more comprehensive and more accurate the monitoring of the dissolved oxygen amount is, and the greater the help of subsequent dissolved oxygen warning and oxygenation relief is, so that the overall cultivation efficiency of the fishpond is improved.
Referring to fig. 4, in order to further improve accuracy of dissolved oxygen monitoring, the step of determining that the difference between the monitored dissolved oxygen and the preset dissolved oxygen is greater than the preset difference includes:
s210, acquiring preset dissolved oxygen amounts in different time periods based on a mapping table;
s220, calculating the difference between the monitored dissolved oxygen amount determined in different time periods and the preset dissolved oxygen amount in the corresponding time period to obtain a difference result;
s230, determining that the difference result is larger than a preset difference value of the corresponding time period.
Specifically, the preset dissolved oxygen amounts of different time periods are obtained from a mapping table, wherein the mapping table is a relation table of time periods and dissolved oxygen amounts stored in a memory, for example, the preset dissolved oxygen amounts are 4mg/L at 18-5 points, 5mg/L at 5-12 points and 6mg/L at 12-18 points, and then difference values between the monitored dissolved oxygen amounts determined in different time periods and the preset dissolved oxygen amounts of corresponding time periods are calculated to obtain difference values; the value of the dissolved oxygen detected at the following 13 minutes in the morning is 3mg/L, namely 3mg/L and 6mg/L in the corresponding time period are subjected to difference calculation to obtain a 3mg/L difference result, and the value of the dissolved oxygen detected at the following 2 minutes in the morning is 2mg/L, namely 2mg/L and 4mg/L in the corresponding time period are subjected to difference calculation to obtain a 2mg/L difference result; and finally judging whether the difference result is larger than a preset difference value of the corresponding time period. Therefore, the dissolved oxygen conditions in different time periods are judged differently according to the actual conditions, and the accuracy of dissolved oxygen detection is further improved.
Referring to fig. 5, the step of obtaining the cleanliness of the fluorescent probe further includes: s500, determining that the cleanliness is larger than or equal to a first preset cleanliness, and determining the monitored dissolved oxygen as an actual dissolved oxygen.
In some embodiments, when the cleanliness of the fluorescent probe 300 is greater than or equal to the first preset cleanliness, it is indicated that there is no effect of impurities on the dissolved oxygen detection, and therefore, it is understood that the monitored dissolved oxygen amount is actually the actual dissolved oxygen amount, that is, no processing is performed on the monitored data.
It should be noted that, although the accuracy of the dissolved oxygen monitoring can be improved to a certain extent by performing the correction processing on the monitored dissolved oxygen amount, the accuracy is definitely not as good as that of the monitored data without any external interference, so in other embodiments, referring to fig. 6, the step of determining that the cleanliness is smaller than the first preset cleanliness or that the difference between the two groups of probes is larger than the maximum difference of the first preset cleanliness, and the step of performing the correction processing on the monitored dissolved oxygen amount to obtain the actual dissolved oxygen content further includes:
and S600, lifting the fluorescent probe, and starting the cleaning device to clean the fluorescent probe.
In this embodiment, water flushing is taken as an example, clean water can be stored in the main device, and when the fluorescent probe 300 needs to be cleaned, the flushing is completed by pressurizing the calibration system, and after the flushing is completed, the fluorescent probe 300 is lowered to continuously monitor dissolved oxygen data.
It will be appreciated that the fluorescent probe 300 is an electronic device, and after a period of use, there is a detection misalignment problem caused by factors such as climate change influence, external force application, etc., and in order to eliminate the detection misalignment problem caused by the problem of the device itself, in some embodiments, referring to fig. 7, the step of obtaining the cleanliness of the fluorescent probe further includes:
s700, automatically calibrating the fluorescent probe;
s800, determining that the automatic calibration process is finished;
s300, acquiring the cleanliness of the fluorescent probe.
Specifically, when it is determined that the difference between the real-time monitored dissolved oxygen amount and the preset dissolved oxygen amount is greater than the preset difference, it is indicated that there is a greater risk in the dissolved oxygen amount, the fluorescent probe 300 is automatically calibrated first to eliminate the interference of the misalignment of the fluorescent probe 300 itself, so that the system is convenient to correct the subsequent dissolved oxygen monitoring data (only consider the influence of a single cleanliness), and the cleanliness of the fluorescent probe is obtained after the end of the automatic calibration process is determined. In this embodiment, after the larger risk is found, by eliminating the interference of the fluorescent probe 300, only the influence of a single cleanliness is considered in the correction of the dissolved oxygen monitoring data, so that the monitoring accuracy is further improved, and the overall culture efficiency of the fish pond is improved.
In this embodiment, the fluorescent probe 300 performs an automatic calibration process (reference may be made to a comparison table of temperature and dissolved oxygen), and the principle of the calibration is common knowledge of those skilled in the art, and will not be described herein.
Referring to fig. 8A, the probe guide rail 200 includes a first guide rail 210 and a second guide rail 220, a first fluorescent probe 310 is disposed on the first guide rail 210, a second fluorescent probe 320 is disposed on the second guide rail 220, and the step of automatically calibrating the fluorescent probe includes:
