Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a management system for a maritime part equipped with a hydrogen gas explosion-

The present invention relates to a management system for a maritime part equipped with a hydrogen gas explosion prevention function, and more particularly, to a maritime part management system for preventing explosion of a light buoy and / or a battery cell by hydrogen gas generated in charging a battery of a light- And more particularly to a management system for a maritime part equipped with a hydrogen gas explosion prevention function. The present invention is a result of research conducted by the Ministry of Commerce, Industry and Energy and the Korea Industrial Technology Development Agency under the "Fusion R & D of Business Development Projects for Economic Cooperation in 2016".

Since there are no sea boundaries or features on the sea, it is not easy to locate with the naked eye. For this reason, a buoy is installed on the sea for a lighthouse that can guide the position of the fishing net, the boundary of the sea, or the route.

On the other hand, a variety of electric devices must be provided in the buoy, such as lighting a lamp at night or installing a speaker to chase gulls. In order to drive such electric devices, it is necessary to provide a battery. Generally, a battery included in a light is operated by a solar panel to store electricity generated by the solar panel, and hydrogen gas is generated in the process of charging the battery through solar power generation. The battery installed in the light guide is made of a closed structure in order to safely protect it from seawater. In such a structure, when the hydrogen gas is generated and accumulated in the inside, the hydrogen gas often explodes.

To solve these problems, various battery gas discharge methods have been proposed. Korean Unexamined Patent Publication No. 2000-0007380, Korean Registered Patent No. 10-1268296, Korean Registered Patent No. 10-1268294, and the like are disclosed in the prior art relating to the gas discharge device inside the battery according to the prior art. These conventional technologies have a cap for discharging gas to the battery case to discharge the hydrogen gas generated in the process of charging the battery as described above.

However, in the related art, there is a limit in that it is not possible to know how much the battery is charged, when the gas is generated mainly, and the like, although the structure that can discharge hydrogen gas is applied to the battery chamber. In the case where the gas discharge structure is merely provided as described above, even if a problem arises in the gas discharge structure, the manager can not know, and if the gas continues to be charged in a state that the manager can not recognize, there is a problem that the storage battery may explode. Therefore, if there is a technology to measure the amount of hydrogen gas generated in a battery in real time, it will be possible to actively respond.

FIG. 1 is a view showing a schematic configuration of a light is applied to a management system for a maritime part having a hydrogen gas explosion prevention function according to the present invention. FIG. 3 is a flowchart showing a management method of a maritime part equipped with a hydrogen gas explosion prevention function. FIG.

1 and 2, a management system for a maritime part equipped with a hydrogen gas explosion-proof function according to the present invention includes a lamp unit 30, a storage battery 77 for supplying power to the lamp unit 30, A hydrogen discharge unit 100 for discharging hydrogen gas generated in the battery 77 to the outside and a hydrogen sensor 52 for measuring the hydrogen gas concentration in the battery 77, (73).

The light-guide table 10 guides a maritime boundary or a running route to a ship which is installed on the sea, and is generally configured as a tower having a buoyant body and a lamp unit 30 at an upper portion thereof. A weight (not shown) is provided at the lower part of the buoyant body so that the buoyant table 10 does not collapse or tilt due to wind or waves. The specific shape of the light guide 10 may be variously designed as needed, and the shape or structure of the light guide 10 does not affect the interpretation of the scope of the present invention.

The lamp unit 30 is provided at an upper portion of the tower of the light table 10 so that light passing through the surrounding area can be easily recognized while emitting light at night. The battery 77 is generally provided inside the buoyant body. Specifically, the battery 77 is provided on the upper portion of the buoyant body so that the charging storage battery 77 is mounted on the storage capacity charging part 70, And is sealed with a cover (75) to prevent seawater, rainwater, etc. from entering into the storage index storage part (70). In the course of this process, hydrogen gas is generated to fill the inside of the storage capacitor charging part 70. In this case, do. If the hydrogen gas generated in the storage index storage portion 70 is not appropriately discharged to the outside, it may be heated by solar heat or the like and may explode. Therefore, the gas discharge portion 100 should be provided and properly discharged. For this reason, most of the power storage index storage unit 70 is provided with the gas discharge unit 100.

The power generation section 50 serves to produce electricity to be stored in the storage battery. Light buoys (10) are often installed on the sea far away from land, and since ships often pass by sea, it is difficult to supply electric power directly by connecting the electric wires on land. Also, the capacity of the battery 75 that can be mounted on the light-guide table 10 is limited because the buoyancy of the buoyancy member must be taken into consideration. It is also difficult to use the battery 75 as a method of replacing the battery 75 at any time. Accordingly, most of the light-guide boards 10 have a structure in which the power generating unit 50 provided therein is directly used to produce electricity. The power generation unit 50 is selectively applied in consideration of the surrounding environment and the like by a known self-power generation system such as a solar panel or a wind power generator. The power generation unit 50 applies a known technique, and a detailed description thereof will be omitted.

The gas discharge unit 100 discharges the hydrogen gas generated inside the charge storage unit 70. The management system for the marine part provided with the hydrogen gas explosion prevention function according to the present invention includes a gas discharge unit 100 An electronic gas discharge unit provided with a pump 71 is applied. In the conventional light-buoy type, when the pressure of the inside of the battery is constant, the nozzle or the valve is opened and the hydrogen gas is discharged or the inside and the outside of the battery are constantly communicating with each other. So that gas can be discharged from time to time. However, since the light buoys installed on the sea are always exposed to natural environments such as rainstorms and strong waves, in the case of the mechanical gas discharge apparatus, malfunctions or seawater flows into the inside in many cases. That is, in the method in which the valve or the nozzle is opened by using the internal pressure, all or part of the portion of the valve or the nozzle which is in contact with the outside is inevitably exposed to seawater. As a result, some components exposed to seawater may not work properly when needed due to corrosion or foreign matter. The structure in which the inner and outer portions are constantly communicated has a special structure such as a twisted path or a shielding structure at the inlet to prevent the seawater from entering the outside. Such a structure makes it impossible to completely block the seawater . Particularly, the mechanical gas discharge device has a greater risk of malfunction when the concentration of hydrogen gas is maintained normally for a long time and the gas discharge portion is not used for a long time.

In addition, since the conventional technology as described above is provided with the gas discharging unit that discharges the gas when the pressure is simply a certain pressure without considering the amount of the hydrogen gas generated in the battery, the generation capacity, And the active countermeasures according to the concentration of the hydrogen gas are insufficient, so that the light buoy may explode even though the gas discharge unit is installed.

2, an internal configuration of a maritime part management system equipped with a hydrogen gas explosion prevention function according to the present invention includes a power generation unit 50, a lamp unit 30, a storage battery 75, a communication unit 60, A detection sensor 40 and a control unit 90. [

The power generation unit 50 may be a solar power panel and / or a wind power generator as described above, and may include a maximum power point tracker (MPPT), a power controller, a converter, and the like as needed. Such a configuration is a well-known configuration that can be generally used in an apparatus for driving a generator, a charger, a lamp unit, and the like. The battery 75 charges the electric energy produced by the power generation unit 50 and the electric power generated by the power generation unit 50 or the electric energy stored in the battery 75 It emits light at night or in rain. The configuration of the power generation unit 50, the lamp unit, and the battery are well known in the art and a detailed description thereof will be omitted.

The battery 75 is provided with an electronic gas pump 71 and is provided with a gas discharging portion 100 for discharging hydrogen gas and a hydrogen sensor 73 for measuring the concentration of hydrogen gas in the storage capacitor charging portion 70 . Thus, when the hydrogen gas concentration in the storage index storage portion 70 becomes equal to or higher than a certain level, the gas discharge portion 100 operates to discharge the hydrogen gas in the storage storage portion to the outside. The management system of the maritime part equipped with the hydrogen gas explosion-proofing function according to the present invention is applied with the electronic gas ejector as described above. However, the electronic gas discharge may not work normally at the required time due to corrosion or errors in electronic equipment. The gas discharge unit 100 of the present invention senses the surrounding environment and periodically drives the gas discharge unit 100 under appropriate conditions to cyclically discharge the hydrogen gas in the storage charge storage unit 70, 100 are operating normally. A specific operation method of the valve for checking the gas exhaust unit 100 will be described later. The pump-type gas discharging portion driven by the electric energy and the hydrogen sensor for measuring the concentration of the hydrogen gas are well-known structures, and a detailed description thereof will be omitted.

The control unit 90 controls the respective components of the management system for the maritime part having the hydrogen gas explosion prevention function according to the present invention and controls the power generation of the power generation unit 50, the charging of the battery 75, The operation of the gas discharger 100, and the operation of the lamp unit 30 are controlled using the hydrogen concentration received from the gas sensor. In addition, the present invention plays a role of directly or indirectly controlling various components necessary for driving the management system of the maritime part equipped with the hydrogen gas explosion prevention function according to the present invention.

The management system of the maritime part equipped with the hydrogen gas explosion-proofing function according to the present invention may further include a state sensing sensor 40 for sensing the surrounding environment and a communication unit 60 for communicating with the land base station. The state detection sensor 40 is constituted by a sensor for measuring whether the buoyant body is shaken or rained by waves. If necessary, an air speed sensor or a temperature sensor for detecting a change in the surrounding environment may be further provided. The sensor having the above-described configuration includes various known configurations such as a gyro sensor, an acceleration sensor, and a rain sensor, and a detailed description thereof will be omitted. The state detection sensor is for checking whether or not the surroundings of the luminaires 10 installed on the sea are stable and judging whether it is appropriate to perform the valve check exhaust. The valve check exhaust will be described later.

3, a management system for a maritime part having a hydrogen gas explosion-proof function according to the present invention is characterized in that a hydrogen sensor 73 installed inside the storage unit 70 is periodically or permanently installed in the storage unit 70 ) Of the hydrogen gas. The hydrogen sensor 73 measures the concentration of the hydrogen gas generated in the course of charging the storage battery by time period, date, or season, and transmits the data value to the land base station using the communication unit 60. At this time, values of ambient temperature and the like measured by the state detection sensor 40 may be transmitted together, if necessary. Various communication means may be applied to the communication unit 60, but CDMA communication is preferably applied.

When a data value related to the occurrence of the hydrogen concentration measured by the hydrogen sensor 73 is received, a server (not shown) on the land base analyzes the data value to calculate the most active time point of generation of hydrogen gas, 10, and the control unit 90 maximizes the efficiency of the exhaust function and the check function by using the time zone in which the generation of the hydrogen gas is most active when the valve check exhaust is described later. The time during which the hydrogen gas is most active is the valve check exhaust time, which is used to check valve exhaust described later. The valve check exhaust will be described later. In addition, various data values received by the server can be used to design hydrogen gas generation rate and the most actively occurring conditions in the process of charging the battery, so that it can be used to design a mechanical gas discharger, This can also be used to design conditions for

On the other hand, as described above, the measurement of the hydrogen gas concentration in the storage index storage section 70 using the hydrogen sensor 73 continues continuously or periodically. In this process, the hydrogen When the gas concentration reaches the dangerous concentration, the gas discharge portion 100 is driven to discharge the hydrogen gas. The hazard concentration is based on the critical point at which hydrogen gas explodes. For example, when the concentration of the hydrogen gas is lower than a critical point for explosion of the hydrogen gas but the concentration of the hydrogen gas is higher than a certain level, the first danger concentration is set. When the first danger concentration occurs, Thereby discharging the hydrogen gas. If the concentration of the hydrogen gas reaches the second danger level by setting the concentration of the second danger concentration to be 10 to 20% lower than the critical concentration at which the hydrogen gas may explode, the charging is immediately stopped and the charging of the storage charge index And simultaneously notifies the manager terminal of the fact by using the communication unit 60 while discharging the hydrogen gas in the gas sensor 70. The reason that the secondary danger concentration has been reached is that the generation of hydrogen gas is excessive or the possibility that the gas exhaust unit 100 is not operated smoothly is high, so that the manager can dispatch the worker immediately and check the condition.

Meanwhile, the management system for a maritime part equipped with the hydrogen gas explosion-proof function according to the present invention may be configured such that the operation of the gas exhaust part 100 is periodically checked separately from the process of measuring the dangerous concentration and discharging the hydrogen gas, And a valve check and evacuation process may be further provided. The valve check and exhaust process periodically operates the gas exhaust unit 100 to discharge the gas in the storage index storage unit 70 when the state of the light board 10 is stable using the state detection sensor 40, (100) is operating normally.

The valve check exhausting process periodically operates the gas exhausting unit 100 to periodically and regularly check whether the operation of the gas exhausting unit 100 normally progresses. By using the status detecting sensor 40, Lt; RTI ID = 0.0 > 10 < / RTI > That is, a gyro sensor, an acceleration sensor, a rain sensor, or the like installed in the light-guide table 10 is used to check whether the waves are intense. If the light buoy is severely shaken by the gyro sensor, it is judged that the wave is severely hit and the valve check exhaust is reserved. Also, if the rain sensor detects rain, keep the valve check exhaust. The discharge of the hydrogen gas by driving the gas discharge part 100 is to open the gas discharge part 100 and to open a part of the storage charge index part 70 with the outside, There is a possibility that rainwater may be introduced. Therefore, the valve check exhaust is performed when the light table 10 is in a stable state. Here, the light table state is a state in which the shake of the light table through the state detection sensor is lower than a predetermined level and does not rain. At this time, the reference value for determining the stable state is variously determined as needed.

The hydrogen gas discharge process of measuring the dangerous concentration as described above proceeds normally when the hydrogen gas reaches a certain concentration or more in the storage index storage part 70 irrespective of the valve check exhaust. Generally, when the wave is heavy or raining, charging is stopped or weakly progressed because it is difficult to generate electric power in the power generation section 50. Therefore, under these environmental conditions, the generation of hydrogen gas is small in the storage index storage portion 70, and the concentration of the hydrogen gas is rarely increased. However, even if the surrounding environment is poor, it is necessary to discharge the hydrogen gas when the hydrogen gas concentration in the storage index storage portion 70 reaches the dangerous concentration. Therefore, when the concentration of the hydrogen gas reaches the predetermined standard by sensing the dangerous concentration, The hydrogen gas must be discharged by operating the fuel cell 100. This is because the loss caused by the explosion of the hydrogen gas is much larger than that caused by opening the gas discharging part 100 in the bad weather (the rainwater or seawater flows into the storage point charging part or the water surface of the gas discharging part shortens).

Meanwhile, in the valve check exhausting process, the valve of the gas exhausting unit 100 is closed and closed at a predetermined period to check whether the gas exhausting unit 100 operates normally, so that the internal hydrogen gas is also discharged naturally. However, since the exhaust for checking the valve is not set at a specific point in time, and it is not necessary to do so frequently, it is preferable to proceed to the timing at which hydrogen gas is generated as much as possible.

For example, when the valve check exhaust is set to be performed once or twice a day or once or twice a week, and when the generation of hydrogen gas is vigorously progressed between 1 and 2 o'clock in the afternoon, And preferably between 1 and 2 o'clock in the afternoon.

As described above, the hydrogen concentration measured periodically by the hydrogen sensor 73 is transmitted to the land base along with the time information. The land based server calculates the change of the concentration value measured by the hydrogen sensor 73, It is determined whether the frequency or amount of occurrence of the hydrogen gas is high or not and the appropriate time to perform the valve inspection and exhaustion is transmitted to the corresponding light table 10 and the light table 10 performs the valve inspection and exhaustion intensively at the time received from the server. Since most light buoys 10 are installed in almost the same environment and conditions, the amount of hydrogen gas generated will be the largest at about the same time. However, the light buoy 10 may be replaced over time, and the newly added light buoy 10 may be different from the existing light buoy, and in some cases, the amount of gas generated may vary depending on the installation location. Therefore, the onshore server can calculate the data value and simultaneously set the valve check exhaust time zone of all light buoys (10) or individually set the time zone where the gas is generated for each light buoy individually.

Valve Check Exhaust closes the valve several times at regular intervals and checks whether the operation of the valve is smooth and if the valve is opened, the hydrogen gas in the charge index discharge is released smoothly. At this time, if it is determined that the operation of the gas discharging unit 100 is not ringed in the valve check exhaust, the on-land manager is notified to the on-land manager through the communication unit 60, .

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
