However, since the prior art detects the marine environment, determines it, and operates the elevating unit that is inserted into the body, there is a high risk of corrosion of the internal structure while being exposed to vibration, salt, moisture, etc. of waves. Because it is powered by, the lighting system may fail.

In other words, the prior art is only to lift and descend so that external influences are not further influenced while already exposed to the marine environment, and if the internal structure is already damaged by the marine environment, the administrator cannot send a signal to notify the outside. It has a problem that it is not possible to know when to replace the battery or whether or not maintenance work is necessary.

First, the offshore structure 2 provided with the lighting system 1 is a structure capable of floating on the surface of the sea, and the lighting system is provided to indicate the existence of an obstacle or a route, thereby further improving the discrimination power.

At this time, the offshore structure is preferably combined with the lighting system using a previously used light buoy, but the offshore structure is not limited to the light buoy, and may be applied to other structures.

In this way, the lighting system is installed on the offshore structure, and by notifying the location of the offshore structure through light, it is possible to guide the location of obstacles or route to the outside.

The lighting system 1 installed in the offshore structure 2 includes a lighting unit 100 that emits light, a sensing unit 200 capable of sensing the internal environment of the lighting system, and the sensing unit 200 sensed from the sensing unit 200. It consists of a determination unit 300 for determining and counting the normal/abnormal state of the lighting system through the sensor module, and a communication unit 400 for communicating notifications for replacement, maintenance, etc. to the outside through the determination unit 300.

The lighting unit 100 includes a combination frame 110 that is directly coupled to the offshore structure, and a light emitting module 120 that is coupled to the combination frame 110 and irradiates light to the outside to determine the location of the lighting system and the offshore structure. It consists of (see Fig. 2 (A)).

The coupling frame 110 is directly coupled to the offshore structure and may include a wire, a circuit, etc. for driving the light emitting module 120.

Such a coupling frame 110 is formed with a recess 111 recessed in the same shape so that the light emitting module 120 can be inserted in the front so that the light emitting module 120 can be fitted, and the coupling frame 110 A plurality of coupling holes 112 for coupling with the offshore structure are provided on the rear side of the panel so that it can be coupled and fixed to the offshore structure through a coupling member (see FIG. 2(B)).

The light emitting module 120 is coupled to the coupling frame 110, and emits light so that the offshore structure can be identified to the outside.

At this time, an identification number indicating the location of the marine structure 2 is displayed on the front of the light emitting module 120, and it is made of a material capable of projecting light irradiated from the light emitting module 120, so it is easy even at night or in rainy weather. You can identify the identification number.

The light-emitting module 120 is composed of one LED lamp and a bundle of optical fibers connecting the same. At this time, the optical fiber bundle maintains visibility by displaying the mark of the light buoy as shown in FIG. 1 as a bundle of optical fibers, and provides long-term light even at low power. Discrimination can also be improved by investigation.

The light-emitting module 120 made of such an LED lamp and an optical fiber bundle has an instantaneous power of about 1.087W, which is used as in the test report of FIG. 6, and is suitable for use as a light-emitting source because there is no change in the ON state for 5 minutes. At the same time, it has the advantage of being able to emit light with super power.

In addition, the light-emitting performance of the light buoy is standardized to enable recognition including luminous intensity and color, but in the present invention, the optical fiber bundle is used in the light-emitting module 120 housing in case the light-emitting member fails to irradiate light due to a failure, etc. This can be prevented by ensuring that it is installed in accordance with the mark marked on.

This light-emitting module 120 can be easily separated and replaced from the coupling frame 110, so installation and maintenance work is simple, and can be easily installed at various positions or heights of the offshore structure through the coupling frame 110. .

In the case of power provided in existing offshore structures, a plurality of light-emitting members such as light bulbs such as incandescent lamps or LEDs are used to provide a plurality of light-emitting members according to the mark. In this case, the power consumed increases, which is a separate power source. There is a discomfort that it is difficult to apply to marine structures that do not exist. By replacing the light emitting member with an optical fiber, power consumption can be reduced.

In other words, in the case of offshore structures, it is difficult to provide a separate power supply means because they float on the sea level for a long period of time, and they must rely on power produced through solar energy such as solar cell modules. Because of this, there is a concern that power supply may not proceed smoothly in case of excessive power consumption. In particular, in the case of offshore structures, there is a need to maintain visibility on a cloudy day or at night. In order to solve this problem, an optical fiber is used as a light emitting source to minimize power consumption.

In addition, a power supply module that is connected to the lighting unit 100 to provide power may be additionally provided.

The power supply module is installed on the top of the offshore structure to generate power through eco-energy. At this time, the eco-energy can be solar or wind, which is selected and installed according to the intention of the installer.

Accordingly, the power generated by the power supply module is used to drive the lighting system, and when the battery is built in and produced more than the power required for driving, it is accumulated in the battery so that it can be used in the future when power is insufficient.

On the other hand, the housing material of the combination frame 110 and the light emitting module 120 described above is made of aluminum, and the housing made of aluminum is strong against salt, has heat resistance, is light, and has the advantage of not changing color.

The detection unit 200 is to check the installation environment and status of the lighting system, and by measuring different sensor data through a plurality of built-in sensor modules, a plurality of heterogeneous sensors rather than detecting the installation environment with only one type of sensor data By integrating the modules, the installation environment can be detected.

The sensing unit 200 is preferably attached to the inside of the coupling frame 110 or the light emitting module 120 of the lighting unit 100, but is not limited thereto.

The sensor module included in the sensing unit 200 may be a humidity sensor, an acoustic sensor, or a 3-axis acceleration sensor, or may include a vibration sensor, a humidity sensor, and a salinity sensor.

Meanwhile, in the present specification, the included sensor module is described as a vibration sensor, a humidity sensor, and a salinity measurement sensor, but the present disclosure is not limited thereto, and the first installer attaches different types of sensor modules according to the intention.

The sensing unit 200 estimates the state of the lighting unit 100 exposed to the outside, detects seawater flowing into the marine structure or the lighting unit 100, and the sensor data detected by each sensor is determined by the determination unit 300 ).

Among the plurality of sensor modules included in the sensing unit 200, the vibration sensor and the 3-axis acceleration sensor detect that the lighting system is excessively shaken by waves, so that seawater may enter the lighting system or collide with an obstacle due to a large wave. As concerns exist, they play a role in detecting them. In addition, the salinity measurement sensor has a role to detect because there is a risk that the internal structure may be corroded or damaged due to an increase in salinity due to seawater that may flow into the lighting system. In addition, the humidity sensor serves to detect when seawater flows into the lighting system or when the internal humidity is excessively increased due to weather, etc., the internal structure may also be corroded and damaged, and the acoustic sensor is used to detect waves or obstacles. By measuring the noise that may be generated during the event, the condition of the wave and the damage of the lighting system are determined.

Therefore, it is possible to detect the state of the lighting system through the above-described sensing unit 200, and through this, an event that will affect the lighting system is detected, and the fatigue level of the lighting system can be measured through the determination unit 300 described later. Make it possible.

For example, if the lighting system vibrates excessively due to a large wave, or increases the salinity and humidity inside the lighting system, the fatigue of the lighting system increases, which in turn adversely affects the performance of the lighting system. And, after detecting an event that increases fatigue through the detection unit 200, the determination unit 300 checks the number of events, etc., and can be transmitted to the manager or management server so that the lighting system can continuously maintain the performance. do.

The determination unit 300 determines whether an event affecting the lighting system from the detection value transmitted through the above-described detection unit 200, determines as a normal state or an abnormal state according to the degree of the detection value, counts, When the number of times of counting is exceeded, a notification is sent to the outside through the communication unit 400.

The determination unit 300 includes a data preprocessing module 310, a weighting module 320, a fusion module 330, and a context information determination module 340.

First, the data pre-processing module 310 collects various types of sensor data detected by the detection unit 200 for each time period, and extracts only event data determined to be abnormal among them and transmits it to the weighting module 320. Plays a role.

That is, the data preprocessing module 310 has an effect of simplifying the time and process required for information processing by processing only event data necessary for situation recognition among sensor data detected over time.

When the event data is initially selected, it is determined based on the range of normal data in the normal state preset in the data preprocessing module 310, and if it exceeds this, it is determined as an event to be selected as event data.

After that, the data preprocessing module 310 accumulates the sensor data determined to be in a normal state, sets the average range of the accumulated sensor data, and then replaces it with the initially set normal data to utilize the normal data range tailored to the surrounding environment where the lighting system is installed. Make it possible.

Through this, only the sensor data determined as event data among the detected values collected over time during operation are separately identified and used for data processing, analysis, and situation information acquisition, so that normal/abnormal state determination can be quickly performed. do.

A weighting module 320 for assigning a weight to the selected sensor data determined by the data preprocessing module 310 as event data is included.

The weighting module 320 determines the difference between the normal data and the value of the data selected as event data, and assigns a weight accordingly.

That is, even if the event data is determined to be the same, not all event data have the same weight, so a weight appropriate to each event data is assigned.

For example, the first event data may exceed the normal data range by a small number, but in the case of the second event data, if the normal data range is excessively exceeded, the second event data is event data closer to occurrence of an abnormal state. Accordingly, by differentially distributing the weights, more accurate abnormal states can be counted.

In addition, weights are not simply assigned only at points exceeding the average range, and weights can be given step by step according to the degree of each difference even when the deviation is large compared to the sensor data in the previous time period.

In addition, when one of the sensor data of the same time zone is determined as event data, a weight is assigned to the other sensor data of the same time zone. That is, since event data detected from multiple sensors is closer to an abnormal state than event data detected by a single sensor alone, weights are given accordingly.

The fusion module 330 collects weighted event data through the weighting module 320, and then converts each event data collected through the time zone detection unit 200 into a common value, and sums it for each time zone. It plays the role of (fusion) processing.

That is, since the sensors included in the sensing unit 200 have different physical properties and units and are collected, each of them is evaluated as a common value and then quantified for each time period. At this time, the event data is converted into an evaluation value between 0 and 1, and each event data converted into an evaluation value is added to the event data of the same time period.

For example, if the event data value acquired by the vibration sensor is 0.5, the event data value acquired by the humidity sensor is 0.7, and the event data value acquired by the salinity sensor is 0.65 at the same time period, the sum of these values is 1.85 (hereinafter , The summed value) is transmitted to the situation information determination module 340.

The situation information determination module 340 is compared with a preset reference value through the value of the sum value through the data preprocessing module 310, the fusion module 330, and the weighting module 320 described above, and experiences normal and abnormal states. Counts the number of times, and outputs a notification to the communication unit 400 when it exceeds a preset abnormal state experience number (n), and the communication unit 400 delivers this to the management server to notify the manager terminal of the replacement or correction of the lighting system. So that it can be sent.

As in the above-described example, since the sum value of 1.85 is a value that exceeds the preset reference value of 1.5, it is determined as an'abnormal state' and the number of abnormal state experiences is counted. After determining as a normal/abnormal state according to the summed value collected as described above, when the abnormal state value exceeds the preset abnormal number, it is possible to notify the outside of the lighting system abnormality, replacement time, etc. through the communication unit 400 described below. do.

The communication unit 400 allows the external management server and the lighting system to interwork with each other, and transmits a replacement/correction notification to the management server so that it can be transmitted to the administrator's terminal.

This communication unit 400 is a fear of high fatigue or damage accumulated in the lighting system 1 when abnormal conditions are counted more than a certain number of normal/abnormal conditions finally determined through the situation information determination module 340 As there is, it is notified to the outside through the management server so that the manager, etc., perform replacement or maintenance work.

In particular, in the case of offshore structures that guide passages or obstacles, they are located far from the land, and there is a difference between the fatigue level of the lighting system according to each location, so that the manager can efficiently manage the lighting system, which is required for management. You can save money, time, and effort.

On the other hand, what has been described with reference to FIGS. 1 to 5 above is only the main matters of the present invention, and as various designs are possible within the technical scope, the present invention is not limited to the configurations of FIGS. 1 to 5 Is self-explanatory.
