[0051] Reference Figure 1The present application provides a maintenance-free and material-saving dissolved oxygen monitoring method, and applies the method to a dissolved oxygen monitoring device, which includes: an equipment body 100, a probe rail 200 arranged on the equipment body 100, a fluorescent probe 300 arranged on the probe rail 200, a cleaning device 400 and a controller 500 arranged on the equipment body 100. The shape of the device body 100 can be in various forms, such as a hull shape, which includes a power supply, a power device and a steering device, can move freely on the surface of the pond, and is controlled by a controller 500; the controller 500 includes a GPS positioning system, a 4G communication module, and has functions such as algorithm downloading and trajectory calculation, and has full automatic control capabilities; the probe guide rail 200 can lift and lower the fluorescent probe 300 under the control of the controller 500, and the lifting and lowering are not limited to the form of realization; the probe adopts a fluorescent probe 300, and the fluorescent probe mainly uses a dynamic fluorescence quenching of a fluorescent material to achieve dissolved oxygen determination. Unlike chemical dissolved oxygen sensor technology, the fluorescent probe does not consume oxygen, has no electrolyte or oxygen permeable membrane, and is basically maintenance-free for daily use; the cleaning device 400 can be set as a water flushing device or an ultrasonic flushing device or a bubble cleaning. The following embodiments are explained by water flushing as an example. Since the fluorescent probe will also encounter problems such as probe dirtiness and detection inaccuracy (such as the impact of climate change, etc.) after being used for a period of time, how to accurately and low-cost monitor the dissolved oxygen content to improve the overall breeding efficiency of the fish pond has become a technical problem to be solved urgently.

[0052] The following will mainly describe the specific steps of a maintenance-free and material-saving dissolved oxygen monitoring method. It should be noted that although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

[0053] Refer to the attached Figure 2 The maintenance-free and consumables-saving dissolved oxygen monitoring method includes the following steps:

[0054] S100, determining the monitored dissolved oxygen content based on the detection value of the fluorescent probe;

[0055] S200, determining that the difference between the monitored dissolved oxygen amount and the preset dissolved oxygen amount is greater than the preset difference;

[0056] S300, obtaining the cleanliness of the fluorescent probe;

[0057] S400: Determine that the cleanliness is less than a first preset cleanliness, or that the difference between the cleanliness of the two groups of probes is greater than a first preset maximum cleanliness difference, and perform correction processing on the monitored dissolved oxygen to obtain an actual dissolved oxygen content.

[0058] Specifically, in this embodiment, the monitored dissolved oxygen amount is first determined based on the detection value of the fluorescent probe; then it is determined that the difference between the monitored dissolved oxygen amount and the preset dissolved oxygen amount is greater than the preset difference; then the cleanliness of the fluorescent probe is obtained; finally, it is determined that the cleanliness is less than a first preset cleanliness, or the difference between the cleanliness of the two groups of probes is greater than the first preset maximum cleanliness difference, and the monitored dissolved oxygen amount is corrected 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 monitored value of the dissolved oxygen amount deviates too much from the preset value, it is judged to be affected by the cleanliness of the fluorescent probe. Therefore, when it is further determined that the cleanliness of the fluorescent probe is less than the first preset cleanliness, the monitored dissolved oxygen amount is corrected to obtain the actual dissolved oxygen content.

[0059] More specifically, the controller 500 receives the electrical signal input from the fluorescent probe, and obtains the monitoring value of the dissolved oxygen after internal calculation processing. The monitoring value can be the monitoring value at a certain moment, or the monitoring value of a certain period of time (a monitoring curve formed by the monitoring values ​​at multiple consecutive moments). The monitoring value at a certain moment is used as an example for explanation below. The preset dissolved oxygen amount can be set individually or comprehensively according to the climate, the power of the oxygen supply machine, or the size and type of different fish schools. In this embodiment, the preset dissolved oxygen amount is 4 mg / L from 18:00 to 5:00, 5 mg / L from 5:00 to 12:00, and 6 mg / L from 12:00 to -18:00. The preset dissolved oxygen amount is the optimal oxygen supply configuration for the fish pond culture. Therefore, when the real-time monitoring When the difference between the dissolved oxygen content and the preset dissolved oxygen content is greater than the preset difference, it means that there is a greater risk of dissolved oxygen content, and the fish in the fish pond are at risk of floating. However, after the fluorescent probe is used for a period of time, it will encounter problems such as dirty probes and inaccurate detection (such as the impact of climate change, etc.), that is, there is a problem of inaccurate monitoring, that is, there is a possibility of misjudgment and false warning. The misjudgment and false warning behavior will seriously affect the overall breeding efficiency of the fish pond. Therefore, this embodiment corrects the detection value by obtaining the cleanliness of the fluorescent probe. When the cleanliness is less than the first preset cleanliness, it means that there are debris such as mosses attached to the fluorescent probe. The attachment of mosses will reduce the detection value of dissolved oxygen. Therefore, it is necessary to correct the monitored dissolved oxygen content to obtain the actual dissolved oxygen content. It can be understood that the lower the cleanliness of the fluorescent probe, the more inaccurate its monitoring value, that is, the smaller the monitored dissolved oxygen detection value, the greater the possibility of misjudgment and false warning.

[0060] There are many ways to obtain the cleanliness of the fluorescent probe 300, such as obtaining it through a micro camera device, through the rising resistance of the fluorescent probe 300, or through the driving power of the head guide 200. Taking camera acquisition as an example, the camera device can be set on the water surface or underwater.

[0061] Due to the different areas of fish ponds, the different fish populations or microbial environments in fish ponds in different areas will affect the dissolved oxygen content. Therefore, it is necessary to monitor the dissolved oxygen content in different directions and routes of the fish ponds to further improve the accuracy and comprehensiveness of the dissolved oxygen monitoring, thereby further improving the overall breeding efficiency of the fish ponds.

[0062] Specifically, refer to the attached Figure 3 , before the step of determining the monitored dissolved oxygen content based on the detection value of the fluorescent probe, the step also includes:

[0063] S000, obtaining the collection route of the dissolved oxygen monitoring equipment;

[0064] S010, controlling the device body to travel along the collection route and keeping the fluorescent probe under the water surface;

[0065] S020. Turn on the fluorescent probe to detect dissolved oxygen and obtain the detection value in real time.

[0066] First, different routes can be stored in the memory, and the routes can be updated regularly. In this embodiment, the processor 500 can obtain any route from the memory for dissolved oxygen monitoring. The processor 500 controls the device body 100 to travel along the collection route and keep the fluorescent probe 200 under the water surface; then turn on the fluorescent probe to detect dissolved oxygen and obtain the detection value in real time; finally, perform steps S100-S400.

[0067] It should be noted that within a day's time period, one or more lines can be selectively monitored for dissolved oxygen. It can be understood that the more line options there are, the wider the range of dissolved oxygen monitoring data will be, the more comprehensive and accurate the monitoring of dissolved oxygen will be, the more help it will provide for subsequent dissolved oxygen warnings and oxygen relief, and the more conducive it will be to improving the overall breeding efficiency of fish ponds.

[0068] Refer to the attached Figure 4 , the optimal configuration of dissolved oxygen and the dissolved oxygen demand are different in different time periods of a day. To further improve the 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:

[0069] S210, obtaining preset dissolved oxygen contents in different time periods based on a mapping table;

[0070] S220, performing difference calculation between the monitored dissolved oxygen content determined in different time periods and the preset dissolved oxygen content in the corresponding time periods to obtain a difference result;

[0071] S230: Determine whether the difference result is greater than a preset difference of a corresponding time period.

[0072] Specifically, the preset dissolved oxygen content of different time periods is obtained from the mapping table, which is a relationship table between time periods and dissolved oxygen content stored in the memory, such as the preset dissolved oxygen content is 4 mg / L from 18:00 to 5:00, 5 mg / L from 5:00 to 12:00, and 6 mg / L from 12:00 to 18:00, and then the difference between the monitored dissolved oxygen content determined in different time periods and the preset dissolved oxygen content of the corresponding time period is calculated to obtain the difference result; for example, the dissolved oxygen value detected at 13:30 in the afternoon is 3 mg / L, that is, 3 mg / L is calculated to be different from 6 mg / L in the corresponding time period to obtain the difference result of 3 mg / L, and the dissolved oxygen value detected at 2 o'clock in the morning is 2 mg / L, that is, 2 mg / L is calculated to be different from 4 mg / L in the corresponding time period to obtain the difference result of 2 mg / L; finally, it is judged whether the difference result is greater than the preset difference of the corresponding time period. In this way, the dissolved oxygen conditions in different time periods are judged according to the actual situation, which is conducive to further improving the accuracy of dissolved oxygen detection.

[0073] Refer to the attached Figure 5 After the step of obtaining the cleanliness of the fluorescent probe, the method further includes: S500, determining that the cleanliness is greater than or equal to a first preset cleanliness, and determining the monitored dissolved oxygen content as the actual dissolved oxygen content.

[0074] In some embodiments, when the cleanliness of the fluorescent probe 300 is greater than or equal to the first preset cleanliness, it indicates that there is no influence of foreign matter on the dissolved oxygen detection. Therefore, it can be understood that the monitored dissolved oxygen amount is actually the actual dissolved oxygen amount, that is, no processing is performed on the monitoring data.

[0075] It should be noted that although the accuracy of dissolved oxygen monitoring can be improved to a certain extent by monitoring the dissolved oxygen content and performing correction processing, its accuracy is certainly not as good as the monitoring data without any external interference. Therefore, in other embodiments, refer to the attached Figure 6 , after determining that the cleanliness is less than a first preset cleanliness, or the difference between the cleanliness of the two groups of probes is greater than a first preset maximum difference in cleanliness, and correcting the monitored dissolved oxygen to obtain the actual dissolved oxygen content, the step further includes:

[0076] S600, lifting the fluorescent probe and starting the cleaning device to clean the fluorescent probe.

[0077] This embodiment is described by taking water flushing as an example. Clean water can be stored in the main device. When the fluorescent probe 300 needs to be cleaned, the flushing is completed by pressurizing the calibration system. After the flushing is completed, the fluorescent probe 300 is lowered to continue monitoring the dissolved oxygen data.

[0078] It is understandable that the fluorescent probe 300 is an electronic device, and after a period of use, there may be detection inaccuracies, such as detection inaccuracies caused by factors such as climate change and external forces. In order to eliminate the detection inaccuracies caused by the device itself, in some embodiments, refer to the attached Figure 7 , before the step of obtaining the cleanliness of the fluorescent probe, the step further includes:

[0079] S700, automatically calibrating the fluorescent probe;

[0080] S800, determining that the automatic calibration process is finished;

[0081] S300: Obtaining the cleanliness of the fluorescent probe.

[0082] Specifically, when it is determined that the difference between the real-time monitored dissolved oxygen and the preset dissolved oxygen is greater than the preset difference, it indicates that there is a greater risk in the dissolved oxygen. First, the fluorescent probe 300 is automatically calibrated to eliminate the interference of the fluorescent probe 300's own inaccuracy, which facilitates the system to correct the subsequent dissolved oxygen monitoring data (considering only the influence of a single cleanliness), and then obtain the cleanliness of the fluorescent probe after determining that the automatic calibration process is completed. In this embodiment, after a greater risk is found, by eliminating the interference of the fluorescent probe 300 itself, the correction of the dissolved oxygen monitoring data only considers the influence of a single cleanliness, which further improves the accuracy of monitoring and is conducive to improving the overall breeding efficiency of the fish pond.

[0083] In this embodiment, the fluorescent probe 300 performs an automatic calibration process (refer to the temperature and dissolved oxygen comparison relationship table). The principle of calibration is common knowledge to those skilled in the art and will not be described in detail here.

[0084] Refer to the attached Figure 8 A, the probe rail 200 includes a first rail 210 and a second rail 220, the first rail 210 is provided with a first fluorescent probe 310, the second rail 220 is provided with a second fluorescent probe 320, and the step of automatically calibrating the fluorescent probe includes:

[0085] S710, lifting one of the first fluorescent probe or the second fluorescent probe to the water surface for calibration, while the other continues to monitor dissolved oxygen;

[0086] Specifically, at least two guide rails are provided on the device body 100, and a fluorescent probe is provided on each guide rail. In this embodiment, the two groups of probes can be calibrated alternately without affecting the data collection process, thereby further improving the accuracy, comprehensiveness and continuous integrity of monitoring.

[0087] Refer to the attached Figure 8B. In other embodiments, the probe rail 200 is provided with a first fluorescent probe 310 and a second fluorescent probe 320 in the height direction, respectively. The step of automatically calibrating the fluorescent probes includes:

[0088] S720. Lift one of the first fluorescent probe or the second fluorescent probe that is close to the water surface to the water surface for calibration, and keep the other one under the water surface to continue to monitor dissolved oxygen.

[0089] Specifically, a guide rail is provided on the equipment body 100, and a plurality of fluorescent probes are respectively provided in the height direction of the guide rail. In this embodiment, the fluorescent probe close to the water surface is lifted to the water surface for calibration by lifting the guide rail, while the other one remains under the water surface to continue to monitor dissolved oxygen, thereby further improving the accuracy, comprehensiveness and continuous integrity of monitoring. Moreover, when the first fluorescent probe and the second fluorescent probe are under the water surface at the same time, the dissolved oxygen content in water at different depths can be detected.

[0090] It can be understood that the lower the cleanliness of the fluorescent probe, the less accurate its monitoring value, that is, the smaller the detected value of dissolved oxygen, the greater the possibility of misjudgment and false alarm. Therefore, in other embodiments, refer to the attached Fig. 9 The step of determining that the cleanliness is less than a first preset cleanliness, or the difference between the cleanliness of the two groups of probes is greater than a first preset maximum difference in cleanliness, and correcting the monitored dissolved oxygen to obtain the actual dissolved oxygen content comprises:

[0091] S410, determining that the cleanliness is less than a first preset cleanliness and greater than or equal to a second preset cleanliness, and correcting the monitored dissolved oxygen content according to the following formula: 实际 =P 监测 +P1;

[0092] Specifically, when the cleanliness is less than the first preset cleanliness and greater than or equal to the second preset cleanliness, it indicates that the cleanliness of the fluorescent probe has a low impact on dissolved oxygen detection, and the actual dissolved oxygen detection value is 实际 With P 监测 The deviation value is small, represented by P1. For example, at a certain moment P 监测 When the dissolved oxygen content is 3 mg / L, the preset dissolved oxygen content in the time period corresponding to this moment is 6 mg / L, and the preset difference is 2 mg / L as an example. Therefore, it can be seen that the monitoring dissolved oxygen content P is affected by the cleanliness. 监测 The difference between the preset dissolved oxygen level (3mg / L) and the preset dissolved oxygen level (6mg / L) (3mg / L) is greater than the preset difference (2mg / L), and the monitored dissolved oxygen level needs to be calibrated and adjusted. 监测 Make it closer to the actual dissolved oxygen detection 实际However, the cleanliness of the fluorescent probe has a low impact on the dissolved oxygen detection at this time. Therefore, the monitored dissolved oxygen is corrected according to the following formula: 实际 =P 监测 +P1; P1 is a smaller value (compared with P2), taking 1.5 mg / L as an example, therefore, P 实际 =P 监测 +P1=3mg / L+1.5mg / L=4.5mg / L. If no correction is performed, the monitored dissolved oxygen (as the actual dissolved oxygen) is 3mg / L, which is seriously lower than the preset dissolved oxygen of 6mg / L. It may issue an erroneous warning message, causing fish pond farmers to panic and make wrong decisions (such as increasing oxygen supply, causing other losses); the actual dissolved oxygen after correction P 实际 =4.5mg / L is also lower than the preset dissolved oxygen content of 6mg / L, but the dissolved oxygen is closer to the actual data, which is more conducive to fish pond farmers making correct decisions and early warnings, and is conducive to improving the overall breeding efficiency of fish ponds.

[0093] S420, determining that the cleanliness is less than a second preset cleanliness, and correcting the monitored dissolved oxygen content according to the following formula: 实际 =P 监测 +P2; wherein the second preset cleanliness is less than the first preset cleanliness, P1<P2, P 实际 is the actual dissolved oxygen content, P 监测 To monitor dissolved oxygen.

[0094] Specifically, in this embodiment, the cleanliness is less than the second preset cleanliness, indicating that the cleanliness of the fluorescent probe has a high impact on the dissolved oxygen detection. 实际 With P 监测 The deviation value is larger, represented by P2. For example, at a certain moment P 监测 When the dissolved oxygen content is 2.5 mg / L, the preset dissolved oxygen content in the time period corresponding to this moment is 6 mg / L. The preset difference is 2 mg / L as an example. Therefore, it can be seen that the monitoring dissolved oxygen content P is affected by the cleanliness. 监测 The difference (3.5 mg / L) between the preset dissolved oxygen level (2.5 mg / L) and the preset dissolved oxygen level (6 mg / L) is greater than the preset difference (2 mg / L). The monitored dissolved oxygen level needs to be calibrated and adjusted. 监测 Make it closer to the actual dissolved oxygen detection 实际 However, the cleanliness of the fluorescent probe has a high impact on the dissolved oxygen detection. Therefore, the monitored dissolved oxygen is corrected according to the following formula: 实际 =P 监测 +P2; P2 is a larger value (compared with P1), taking 2.5 mg / L as an example, therefore, P 实际 =P 监测+P2=2.5mg / L+2.5mg / L=5mg / L. If no correction is performed, the monitored dissolved oxygen (as the actual dissolved oxygen) is 2.5mg / L, which is seriously lower than the preset dissolved oxygen of 6mg / L. It may issue an erroneous warning message, causing fish pond farmers to panic and make wrong decisions (such as increasing oxygen supply, causing other losses); the actual dissolved oxygen after correction P 实际 Although =5mg / L is also lower than the preset dissolved oxygen content of 6mg / L, the dissolved oxygen is closer to the actual data, which is more conducive to fish pond farmers making correct decisions and early warnings, and is beneficial to improving the overall breeding efficiency of fish ponds.

[0095] In this way, the dissolved oxygen monitoring method and monitoring device of the present application do not require manual operation throughout the entire process, and are maintenance-free and do not require consumption of consumables. They can accurately and low-cost monitor the dissolved oxygen content, save breeding costs, and are conducive to improving the overall breeding efficiency of the fish pond; at the same time, the dissolved oxygen monitoring method of the present application can accurately and low-cost monitor the dissolved oxygen content, providing correct and accurate decision-making basis for subsequent oxygen supply, oxygenation, etc.

[0096] An embodiment of the present invention further provides a dissolved oxygen monitoring device, comprising a memory, a processor, and a control program stored in the memory for implementing a dissolved oxygen monitoring method, wherein the processor is used to execute the control program for implementing the dissolved oxygen monitoring method to implement the following steps of the dissolved oxygen monitoring method:

[0097] Determine and monitor the dissolved oxygen content based on the detection value of the fluorescent probe;

[0098] Determining that the difference between the monitored dissolved oxygen amount and the preset dissolved oxygen amount is greater than the preset difference;

[0099] Obtaining the cleanliness of the fluorescent probe;

[0100] It is determined that the cleanliness is less than a first preset cleanliness, or the difference between the cleanliness of the two groups of probes is greater than a first preset maximum difference in cleanliness, and the monitored dissolved oxygen content is corrected to obtain the actual dissolved oxygen content.

[0101] The embodiment of the present invention further provides a readable storage medium, on which a control program is stored. When the control program is executed by a processor, the following steps of the dissolved oxygen monitoring method are implemented:
