원자력 발전소 화재방호용 비상통신시스템 {Emergency Communication System For Fire Protection Of Nuclear Power Plants}Emergency Communication System For Fire Protection Of Nuclear Power Plants

본 발명은 원자력 발전소 화재방호용 비상통신시스템에 관한 것이고, 더욱 상세하게는 원자력 발전소에 화재가 발생하여 유선통신이 손상되는 경우에 운전원 및 소방대간에 유무선 혼합형태의 비상통신시스템을 이용하여 상호 의사전달이 가능하여 효과적인 화재진압 및 안전운전을 도모할 수 있는 원자력 발전소 화재방호용 비상통신시스템에 관한 것이다.The present invention relates to an emergency communication system for fire protection of a nuclear power plant, and more particularly, to communicate with each other by using an emergency communication system of a mixed wired and wireless type between an operator and a fire brigade when a fire occurs in a nuclear power plant and damage to wired communication. To this end, the present invention relates to an emergency communication system for fire protection of nuclear power plants, which can promote effective fire suppression and safe operation.

원자력 발전소 화재방호 기준에서는 운전원 및 소방대용으로 무선통신설비를 갖출것을 요구하고 있다. 그러나 원자력발전소 주요 건물은 방사선 차폐를 위해 두꺼운 콘크리트 구조로 이루어져 있으므로 콘크리트에 의해 전자파가 차단되므로 무선통신이 용이하지 않다.Nuclear power plant fire protection standards require the installation of wireless communications equipment for operators and fire brigade. However, since the main building of nuclear power plant is made of thick concrete structure for shielding radiation, it is not easy to communicate wirelessly because electromagnetic waves are blocked by concrete.

또한 무선통신을 사용할 경우 발생하는 전자기파 및 고조파에 의해 계전기와 같은 계측제어설비의 오동작 우려가 있어 현재까지 국내에서는 무선통신설비의 사 용이 금지되어 있다.In addition, the use of radio communication equipment has been prohibited in Korea.

국내 소방관련법에서는 지하층 면적이 일정기준 이상일 경우에 무선통신보조설비를 요구하고 있다.Domestic firefighting laws require wireless telecommunication aids if the basement floor area is above a certain standard.

그러나, 무선통신보조설비에서 사용하는 누설동축 케이블은 화재에 비교적 약한 재질이므로 화재시에는 케이블이 손상되어 통신 기능이 상실될 수 있다.However, since the leaky coaxial cable used in the wireless communication auxiliary equipment is a relatively weak material for fire, the cable may be damaged and the communication function may be lost.

또한 무선통신보조설비는 일반적으로 출력이 큰 무전기(0.5W이상)를 사용하게 되어 계측제어설비에 전자파 장애가 우려되므로 원자력 발전소에는 적합하지 않은 문제가 있었다.In addition, wireless communication auxiliary facilities generally use radios having a large output (0.5 W or more), which is not suitable for nuclear power plants because electromagnetic interference is a concern for measurement and control equipment.

상기와 같은 문제점을 해소하기 위해서는 원자력 발전소 특수성을 고려하여 계측제어설비의 전자파 장애를 유발하지 않으면서도 무선통신 기능을 만족시킬 수 있는 통신설비 개발이 필요하다.In order to solve the above problems, it is necessary to develop a communication facility that can satisfy the wireless communication function without causing electromagnetic interference of the measurement control equipment in consideration of specificity of the nuclear power plant.

상기와 같은 문제점을 해결하기 위해 안출된 것으로써 본 발명의 목적은 원자력발전소와 같은 콘크리트 건물내에서 방화지역간에 무선통신이 가능하고, 무선통신설비에서 발생하는 전자기파로 인해 계측설비의 오작동 우려가 없으며, 화재가 발생하는 경우에도 통신기능이 손상되지 않는 원자력 발전소 화재방호용 비상통신시스템을 제공하는 데 있다.In order to solve the above problems, an object of the present invention is to enable wireless communication between fire zones in concrete buildings such as nuclear power plants, and there is no fear of malfunction of the measuring equipment due to electromagnetic waves generated from the wireless communication facilities. In addition, the present invention provides an emergency communication system for fire protection of nuclear power plants, in which a communication function is not impaired even in the event of a fire.

상기와 같은 목적을 달성하기 위해 본 발명에 따른 원자력 발전소 화재방호용 비상통신시스템은 외부 무전기, 무선기지국 및 발전소 내부 통신설비를 포함하여 유/무선 복합으로 통신이 가능한 원자력 발전소 비상통신시스템에 있어서, 상기 발전소 내부 통신설비는 방화지역에 설치된 리모트 무전기와 상기 리모트 무전기와 콘크리트 차폐벽을 통해 통신선에 의해 연결된 발전소 내부 회선분배기를 포함하는 것을 특징으로 한다.In the nuclear power plant fire protection emergency communication system according to the present invention in order to achieve the above object in the nuclear power plant emergency communication system that can communicate in a wired / wireless hybrid, including an external radio, radio base station and internal communication facilities in the power plant, The communication equipment inside the power plant is characterized in that it comprises a remote transceiver installed in the fire zone and the power distribution circuit inside the power plant connected by a communication line through the remote radio and the concrete shielding wall.

여기서, 상기 리모트 무전기는 전자파로 인해 발전소 계측설비에 영향이 없도록 출력이 10mW이하인 것이 바람직하다.Here, the remote radio is preferably output less than 10mW so as not to affect the power plant measurement equipment due to electromagnetic waves.

그리고, 상기 통신선은 화재에 손상되지 않은 내화등급 전선으로 형성된 것을 특징으로 한다.In addition, the communication line is characterized in that formed of fire-resistant wire is not damaged by fire.

또한, 상기 통신선은 외부에 화재로부터 통신선을 보호하는 화재방호체가 형 성된 것을 특징으로 한다.In addition, the communication line is characterized in that the fire protection body for protecting the communication line from the outside is formed.

상기의 과제 해결 수단을 통해 살펴본 바와 같이, 본 발명에 따른 원자력 발전소 화재방호용 비상통신시스템은 리모트 무전기를 무선통신이 필요한 건물내부 방화지역에 배치하고 이를 유선으로 연결함으로써 콘크리트의 전파차단으로 인해 무선통신이 부적합한 원자력발전소에서도 무선통신이 가능한 효과가 발생한다.As discussed through the above problem solving means, the emergency communication system for fire protection of a nuclear power plant according to the present invention has a wireless radio by placing a remote radio in a fire protection area inside a building that requires wireless communication and connecting it by wire to prevent radio waves of concrete. Even in nuclear power plants where communication is inadequate, wireless communication is possible.

또한, 리모트 무전기는 출력이 매우 낮은 무전기를 사용하므로 전자파로 인한 계측제어설비의 오작동 우려를 해결하였고, 건물내부의 통신선은 내화등급 케이블 또는 통신선 외부에 화재방호체를 형성하여 화재가 발생하는 경우에도 통신기능이 유지되는 효과가 발생한다.In addition, since remote radios use very low power radios, they have solved the possibility of malfunction of measurement and control equipment due to electromagnetic waves.In the case of a fire occurring due to the formation of a fire protection body outside a fireproof cable or communication line The effect of maintaining the communication function occurs.

따라서, 본 발명은 원자력 발전소의 특수성을 고려하여 개발한 유무선 혼합형태의 비상통신설비로서 원자력 발전소 화재방호 기준을 만족시킴은 물론 이를 현장에 적용함으로써 원자력 발전소의 화재안전성을 크게 향상시킬 수 있는 탁월한 효과가 발생한다.Therefore, the present invention is an emergency communication facility of a mixed wired and wireless type developed in consideration of the specificity of the nuclear power plant, which satisfies the fire protection standards of the nuclear power plant, as well as applying it to the field, which can greatly improve the fire safety of the nuclear power plant. Occurs.

이하, 본 발명의 구체적인 실시예에 대하여 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 바람직한 실시예에 따른 원자력 발전소 화재방호용 비상통 신시스템을 개략적으로 도시한 것이다.1 schematically illustrates an emergency communication system for fire protection of a nuclear power plant according to a preferred embodiment of the present invention.

도 1을 참조하면, 본 발명에 따른 비상통신 시스템은 발전소 내부 통신설비와 외부 통신설비로 나눌수 있다.Referring to FIG. 1, the emergency communication system according to the present invention may be divided into an internal communication facility and an external communication facility of a power plant.

외부 통신설비는 안전원등이 외부에서 무선신호를 송수신하는 무전기(230)와 상기 무전기로부터 송신된 신호가 무선으로 전송되는 무선기지국(220)과 상기 무선기지국을 통해 신호가 전송되는 외부 회선분배기(210)를 포함하여 구성될 수 있다.The external communication facility includes a radio 230 for transmitting and receiving a radio signal from a safety source, a radio base station 220 through which a signal transmitted from the radio is transmitted wirelessly, and an external line divider through which the signal is transmitted through the radio base station. 210 may be configured to include.

그리고, 내부 통신설비는 방화지역에 설치된 리모트 무전기(130)와 상기 리모트 무전기와 콘크리트 차폐벽(110)을 통해 통신선(140)에 의해 연결된 발전소 내부 회선분배기(120)를 포함하여 구성될 수 있다.In addition, the internal communication facility may include a remote transceiver 130 installed in the fire protection area and the power line inside the power distribution unit 120 connected by the communication line 140 through the remote radio and the concrete shielding wall 110.

따라서, 외부와 내부에서는 외부 무전기(230)와 내부 리모트 무전기(230)를 통해 무선으로 통신을 수행하지만, 망 구성에 있어서 외부 통신설비와 내부 통신설비를 유선과 무선을 복합적으로 이용하여 시스템을 구현한다. Therefore, the outside and the inside performs the wireless communication through the external radio 230 and the internal remote radio 230, but in the network configuration to implement a system using a combination of the external communication equipment and the internal communication equipment wired and wireless do.

상기 외부 통신설비의 회선분배기(210)와 내부 통신설비의 회선분배기(120)가 통신선으로 연결되어 외부통신설비와 내부통신설비가 연결된다.The line divider 210 of the external communication facility and the line divider 120 of the internal communication facility are connected by a communication line to connect the external communication facility and the internal communication facility.

원자력발전소 주요 건물(격납건물, 보조건물, 핵연료건물 등)의 외벽, 바닥, 천장 등은 방사선 차례를 위해 두꺼운 콘크리트 구조로 이루어져 있어 일반적인 무선통신설비 적용이 용이하지 않다.The outer walls, floors, and ceilings of major buildings (containment buildings, auxiliary buildings, nuclear fuel buildings, etc.) of nuclear power plants are made of thick concrete structures for the turn of radiation.

즉, 발전소 외부와 건물 내부는 물론 발전소 내부지역 간(예를 들어, 도 1의 방화지역 1, 2, 4)에도 콘크리트 차폐벽으로 인해 전자파가 차단되어 무선통신이 곤란하다.That is, it is difficult to communicate wirelessly because electromagnetic waves are blocked by the concrete shielding wall between the outside of the power plant and the inside of the building, as well as between areas of the power plant (for example, the fire zones 1, 2, and 4 of FIG. 1).

이러한 문제를 해결하기 위한 방안으로 리모트 무전기(130)를 무선통신이 필요한 방화지역마다 설치하여 이를 통신선(140)으로 연결한다.In order to solve this problem, the remote walkie-talkie 130 is installed in each fire protection area requiring wireless communication and is connected to the communication line 140.

이 때 리모트 무전기(130) 사이를 연결하는 통신선(140)은 화재에 손상되지 않는 내화등급 전선을 사용하거나 또는 통신선을 화재로부터 보호할 수 있는 화재방호체(Fire protection wrapping)을 외부에 시공하여 화재가 발생하더라도 통신기능이 유지되도록 할 수 있다.At this time, the communication line 140 connecting between the remote radios 130 uses fire-resistant wires that are not damaged by fire, or constructs a fire protection wrapping to protect the communication lines from the fire. Communication function can be maintained even if

건물내부에 시공된 통신선(140)은 통신실의 회선분배기(120), 건물외부의 회선분배기(210), 무선기지국(220)에 연결된다.The communication line 140 constructed in the building is connected to the line splitter 120 in the communication room, the line divider 210 outside the building, and the wireless base station 220.

이때 통신실의 회선분배기(120)로부터 무선기지국(230)까지의 통신선은 일반적인 통신선을 사용할 수 있다.At this time, a communication line from the line divider 120 to the wireless base station 230 in the communication room may use a general communication line.

발전소 건물내에 사용하는 리모트 무전기(130)는 출력이 10mW 이하인 것을 사용하여 무전기에서 발생하는 전자파로 인해 발전소 계측설비에 영향이 없도록 할 수 있다.The remote radio 130 used in the power plant building may use an output of 10 mW or less so that the electromagnetic wave generated from the radio does not affect the power plant measurement equipment.

리모트 무전기(130)가 설치된 방화지역 내에서는 무선전화를 사용하는 것과 같이 리모트 무전기를 사용할 수 있다.Within the fire zone in which the remote radio 130 is installed, the remote radio may be used as if using a wireless telephone.

본 발명에 따른 통신 설비는 리모트 무전기(130)가 설치된 방화지역간(방화지역 1, 2, 4)에는 무선통신이 가능하지만 리모트 무전기(130)가 설치되지 않은 지역(방화지역3)에는 통신이 불가능하다. The communication equipment according to the present invention is capable of wireless communication between fire zones (fire zones 1, 2, and 4) in which the remote radio 130 is installed, but not in an area (fire zone 3) where the remote radio 130 is not installed. Do.

발전소 외부지역은 전자파로 인한 계측설비 장애 우려가 없으므로 일반적인 무전기를 사용할 수 있다. Outside the power plant, general radios can be used because there is no risk of measurement equipment failure due to electromagnetic waves.

따라서, 발전소 내부에서는 리모트 무전기(130)를 사용하고 발전소 외부에서는 일반 무전기(230)를 사용하여 상호 통신이 가능하다.Therefore, the remote radio 130 is used inside the power plant and the general radio 230 is used outside the power plant to communicate with each other.

이상에서 설명한 본 발명의 상세한 설명에서는 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 본 발명의 보호범위는 상기 실시예에 한정되는 것이 아니며, 해당 기술분야의 통상의 지식을 갖는 자라면 본 발명의 사상 및 기술영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.Although the detailed description of the present invention described above has been described with reference to the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, and those skilled in the art will appreciate It will be understood that various modifications and changes can be made in the present invention without departing from the spirit and scope of the invention.
