Recently, as the development of the ocean is accelerated in order to solve the depletion of land resources, population density, etc., underwater structures such as marine plants, bridges, and undersea tunnels are being built. Accordingly, the demand for technology for monitoring the environment of aquatic organisms living in the water is also increasing.

For such underwater monitoring, a method in which a diver submerged and directly photographed and directly inspected an image of an aquatic organism was conventionally used.

However, this conventional monitoring method for capturing underwater images not only carries the risk of human accidents, but also has limitations in image acquisition time and range because it is affected by conditions such as divers, weather, and the sea. In addition, since an expert in underwater environment analysis needs to analyze the underwater environment based on a two-dimensional image having a low sense of realism, there is a problem in that the accuracy of the analysis result is inevitably lowered.

Furthermore, in the conventional method of monitoring aquatic life, etc., since an aquatic environment analysis expert must analyze the aquatic environment based on a two-dimensional image with a low sense of realism, there is a problem in that the accuracy of the analysis result is inevitably reduced.

Therefore, in order to obtain information necessary for location recognition in an underwater environment, various studies have been conducted on monitoring of aquatic organisms using virtual reality, including searching for underwater objects using underwater image information.

The virtual reality (VR) is an interface between a human and a computer that creates a desired specific environment or situation with an information processing device such as a computer and makes the user feel as if they are interacting with the actual surrounding situation and environment. says In order for the user to feel a sense of reality through virtual reality, information acquired through the user's five senses, such as sight, hearing, and touch, must be provided. Therefore, a monitoring method applying the virtual reality (VR) is also gradually emerging.

Using virtual reality with these functions, it is possible to more accurately grasp the state of the aquatic environment that can monitor current aquatic organisms than the prior art in order to minimize direct and indirect effects caused by the aquatic environment, and analyze data. The development of a detection system or monitoring system and method that can be easily understood and efficiently utilized results has been required.

In order to efficiently process whether or not the monitoring device 100 has an abnormality based on data, the management information processing device 300 from the following preprocessing configuration For example, data may be preprocessed for each device. Specifically, this preprocessing is performed as follows.

a) First, collect data in real time, including pressure, temperature, etc.

b) Then, operational operational data is extracted from the start to the end of a pre-specified operation.

c) Then, different facility codes and, for example, operation data collected for each operation start and end time of the monitoring device 100 are registered.

d) Next, based on the registered result, data is extracted for each different facility by a certain range.

e) Therefore, data is registered by operation operation code (including operation code, date, time, pressure, temperature, etc.) using the result extracted in this way.

Therefore, when performing maintenance monitoring, such a failure diagnosis system collects various data, extracts operational data in work units from the operation start time to the end time for each component, and pre-processes the data.

Therefore, in the case of such monitoring, whether or not the monitoring device 100 is abnormal according to data from the preprocessing configuration is efficiently processed, and through this, maintenance is more effectively monitored.

Hereinafter, the data structure collected in the pre-processing process will be described.

First, the data structure is a structure that collects data from the controllers 200-1 to 200-n in real time by equipment and by status (temperature, etc.) in the case of the above-mentioned monitoring, and is transmitted by code of the device. Collect data.

And, the data structure is an operating structure that automatically collects start and end times of performing tasks for each device or as an operator's input, and stores state information for each task.

Next, when the final diagnostic prediction model is created through this, it is a data structure combined by the finally extracted operating unit to be used. This exists as a file for each operating code, and in each file, data is combined from the date and time of operation start to the end.

Since maintenance is also performed through preliminary diagnosis according to data analysis, optimized maintenance is performed, and the management information processing device 300 performs the following operation.

First, when the current state information is transmitted, the management information processing device 300 compares the reference state attribute information of the monitoring device 100 of the present invention and the current state attribute information by type from a pre-registered time series diagnostic prediction model. .

As a result of the comparison, if the difference between the reference state attribute information and the current state attribute information is within a preset error range, it is diagnosed as normal, and if not, it is diagnosed as a failure. let me know if it's normal In this case, the time series diagnostic prediction model is implemented as follows according to an embodiment.

First of all, the time series diagnostic prediction model is a model that classifies and learns the time required for each of a number of different components and surrounding environment elements and status information for each operating time period when diagnosing whether the monitoring device 100 is out of order. define.

At this time, the learning model is as follows.

1) A data set representing the operation and environmental state characteristics for each of a number of different components and surrounding environment elements is extracted.

2) Next, the dataset extracted in this way is attributed by reflecting information of a plurality of different operating time zones and surrounding environments.

3) Then, on the basis of the attributable result, the required time and the attributes of the state information are determined by information maintaining the same state for a period representing a persistence characteristic for each learning model.

4) And normalize these determined results.

5) Therefore, based on these normalized results, the required time and state attribute information are set for each learning model, and information for predicting the required time and state attribute information for each of a number of different components and surrounding environment elements is generated. set as independent (standard state attribute information) and dependent (state) variables.

6) Then, the result set in this way is created as learning and training data.

7) Therefore, a time-series diagnostic prediction model based on deep learning is created from the generated data.

Additionally, the time series diagnostic prediction model will be further described as follows.

First, when various data for monitoring are transmitted, there are cases where a large number of data is not collected due to errors in communication, IoT devices, devices, etc., or abnormal values such as temperature occur, and the data file must be removed. .

So, after creating the basic dataset through this, additionally add attributes for the cumulative required time and status. In addition, if some data is not collected due to data disconnection, the corresponding data is removed. In this case, in order to use the time series-based deep learning learning model according to an embodiment, a serial data set must be created by setting a certain serial input length and step. So, next, valid properties for each model are determined, normal values are generated, and independent and dependent variables are determined. For example, in the required time model, cumulative amount and cumulative state may be valid dependent variables, and information indicating a failure state, that is, reference state attribute information may be set as an independent variable.

Then, in order to create a learning model, learning and training data are created from among the entire data. In general, 70% of the entire dataset is used as training data and 30% is used as training data to test the model after creating a model. Next, we create the learning model. At this stage, you decide which learning model to use. For example, it refers to a configuration that sets the maximum number of outputs by configuring an input layer and an output layer by configuring necessary layers based on deep learning. The generated model is evaluated, and if the error rate is satisfied, the model is simulated with new data, and if the model update is not required, the learning model is saved and used as a prediction model.

8 is a flowchart illustrating the operation of the fault diagnosis system.

As shown, first, a plurality of IoT sensors (I) are installed for each device and each element of the surrounding environment to detect state information from each element when the monitoring device 100 is operated.

At this time, the controller 200 transmits the current status information to the pre-registered management information processing device 300 when status information is sensed by the plurality of IoT sensors I.

Next, by controlling the management information processing device 300, the operation is differently adjusted for each type.

In this case, the management information processing device 300 pre-registers information for controlling different operations according to different devices based on manager setting information. So, when the current state information is transmitted from the controller 200, the current state is determined from the registered result and the operation of the monitoring device 100 is differently integrated and controlled.

So, when the monitoring device 100 of the present invention is operated through this, state information is collected, data is processed, and an abnormal situation is sensed and analyzed to perform maintenance. For example, when a sudden increase in pressure, temperature, rapid end of operation, or non-collection of data occurs, an abnormality notification may be provided.

In addition, when maintenance is performed in this way, maintenance of the monitoring device 100 is also performed through preliminary diagnosis according to data analysis, so that optimized maintenance can be performed.

To this end, the failure diagnosis system performs the following operations.

First, when the status information of the current monitoring device 100 is transmitted, the management information processing device 300 obtains reference state attribute information and current state attribute of the device from a pre-registered time-series diagnostic prediction model (see the above). Compare information by device type.

As a result of the comparison, when the difference value between the reference state attribute information and the current state attribute information corresponds to a preset reference difference value, it is diagnosed as normal.

On the other hand, as a result of the comparison, if the difference value between the reference state attribute information and the current state attribute information does not correspond to the reference difference value, the monitoring device 100 is maintained because it is diagnosed as a failure.
