EXAMPLE III
The present embodiment is different from the second embodiment in that:
in this embodiment, breed the quantity of monitoring component 6 and be a plurality of to three breed monitoring component 6 and explain as the example, three breed monitoring component 6 equidistance sets up on expansion plate 4 for gather the quality of water parameter of the different degree of depth of breeding the pond. As shown in fig. 4, the server further includes an anomaly fitting module, a difference value judging module, a difference value calculating module, and an instruction generating module.
The server is also used for comparing the water quality parameters collected by all the breeding monitoring assemblies 6, and when the difference value between the water quality parameter corresponding to any one breeding monitoring assembly 6 and the rest water quality parameters is larger than a preset abnormal difference value, an abnormal reminding signal is generated. Specifically, the abnormal fitting module is used for fitting according to all the water quality parameters to obtain a fitting curve, and calculating the difference value between each water quality parameter and the fitting curve according to the fitting curve and the water quality parameters. The difference value judgment module is preset with an abnormal difference value, and the abnormal difference value is the maximum value of the difference of different breeding monitoring assemblies 6 which can be accepted by the system. The difference value judging module is used for judging whether the difference value between each water quality parameter and the fitting curve is larger than the abnormal difference value or not, and when any difference value is larger than the abnormal difference value, an abnormal reminding signal is generated.
The storage module stores the installation distances of the culture monitoring assemblies 6 at intervals, and is also used for recording the corresponding water quality parameters and the acquisition heights when generating the abnormal reminding signals, namely recording the water quality parameters corresponding to the difference values larger than the abnormal difference values and the acquisition heights of the culture monitoring assemblies 6.

Specifically, the instruction generation module generates diagnosis control information according to the installation distance, when the acquisition height is the minimum value, the corresponding cultivation monitoring assembly 6 is located at the bottommost end, the telescopic mechanism needs to be controlled to move upwards, correspondingly, when the acquisition height is the maximum value, the corresponding cultivation monitoring assembly 6 is located at the topmost end, and the telescopic mechanism needs to be controlled to move downwards.
The control terminal is configured to control the telescopic mechanism to slide along the blocking plate 1 according to the diagnosis control information, so that another cultivation monitoring component 6 is located at the depth, for example, three cultivation monitoring components 6 are exemplified in the present embodiment, and for convenience of distinction, the cultivation monitoring components 6 are respectively defined as A, B, C corresponding to the collection heights x, y, and z from top to bottom. When the water quality parameter that breed monitoring components 6B gathered differed with the water quality parameter that breed monitoring components 6A, C gathered greatly, control expansion plate 4 lapse installation distance, and the degree of depth of breeding monitoring components 6A was for gathering height y this moment, and the degree of depth of breeding monitoring components 6B was for gathering height z.
The server is also used for recording the water quality parameters with the same acquisition height after the barrier plate 1 finishes sliding, comparing the water quality parameters recorded twice, and generating a water pollution signal when the difference value of the water quality parameters recorded twice is smaller than the preset overflow difference value, otherwise, generating an equipment maintenance signal. Specifically, the difference calculation module is used for recording the water quality parameters with the same acquisition height after the barrier plate 1 slides, namely, the acquisition height y corresponds to the water quality parameters acquired by the current breeding monitoring assembly 6A and the acquisition height y corresponds to the water quality parameters acquired by the historical water quality detection assembly B, and calculating the difference of the two water quality parameters. In order to ensure that the water quality parameters collected by the culture monitoring assembly 6 reflect the condition of the culture water body more accurately, thirty minutes or sixty minutes of delay is carried out after the stop plate 1 finishes sliding, and the water quality parameters are recorded after the culture water body is stabilized.
The difference value judging module is also used for judging whether the difference value of the water quality parameters at the same acquisition height is larger, judging whether the difference value of the water quality parameters at two times is smaller than the difference value of the overflow amount, generating a water pollution signal when the difference value of the water quality parameters at two times is smaller than the difference value of the overflow amount, and generating an equipment maintenance signal when the difference value of the water quality parameters at two times is equal to or larger than the difference value of the overflow amount.
When the water quality parameters collected by a certain cultivation monitoring component 6 are obviously different from the water quality parameters collected by the rest cultivation monitoring components 6, two conditions exist, namely the water body of the area where the cultivation monitoring component 6 is located is abnormal, and the cultivation monitoring component 6 is abnormal. According to the scheme, the blocking plate 1 is controlled to slide, so that the other cultivation monitoring component 6 on the blocking plate 1 moves to the position of the cultivation monitoring component 6 in the cultivation pond, water quality parameters are collected at the same position through two times of different cultivation monitoring components 6 for comparison, judgment is carried out according to the comparison result, when the difference of the water quality parameters of the two times is not large, namely, the cultivation water body in the area in the cultivation pond is abnormal, a water body pollution signal is generated at the moment, and a worker is reminded to treat the cultivation water body; when the two times of water quality parameters have large differences, the cultivation monitoring assembly 6 is represented to be abnormal, and an equipment maintenance signal is generated at the moment to remind a worker to maintain and replace the cultivation monitoring assembly 6. The scheme of the adoption automatically analyzes the abnormal condition of the water quality parameters, reminds workers according to the analysis result, improves the abnormal judgment efficiency and reduces the workload of the workers.
