본 발명은 동절기에 물감지부에 의하여 눈이나 빗물와 같은 유체가 계측되는 경우, 온도감지부에 의하여 도로 노면 상의 온도를 측정하고, 측정된 도로 노면상의 온도가 설정온도 범위 내에 있는 경우 컨트롤부는 결빙구간으로 판단하여 염수살포수단을 통해 해당 결빙구간으로 염수를 살포함으로써 도로 노면 상의 상습 결빙구간을 신속하게 제거하고, 이를 통하여 차량의 안전 운행을 도모할 수 있는 도로 노면의 액체 및 온도 감지기능을 갖는 염수살포시스템에 관한 것이다.In the present invention, when a fluid such as snow or rainwater is measured by the water detection unit in winter, the temperature on the road surface is measured by the temperature detection unit, and when the measured temperature on the road surface is within the set temperature range, the control unit moves to the freezing section. Salt water spraying with a function of detecting liquid and temperature on the road surface, which can quickly remove the habitual freezing section on the road surface by judging and spraying salt water into the corresponding freezing section through the salt water spraying means, and thereby promote the safe operation of the vehicle.

일반적으로 겨울에 도로에 눈이 내리게 되면, 주행 중이던 차량이 미끄러지면서 대형 교통사고를 유발시키게 된다. 따라서, 강설 시에는 신속하게 제설액을 도로에 분사하여 눈을 제거해야 할 필요성이 있다.In general, when snow falls on the road in winter, a vehicle that was running slips and causes a large traffic accident. Therefore, during snowfall, there is a need to remove snow by rapidly spraying the snow removal solution onto the road.
이러한 필요에 의해서 도로의 노견 바깥에 제설액 탱크를 설치하고, 상기 탱크에 분사관으로 연결된 펌프가 구성되고, 상기 펌프에 분사관으로 연결된 분사노즐이 구성된다. 그리고 상기 펌프에는 통신부가 접속되고, 상기 통신부는 관리자의 단말기에 인터넷망으로 통신 가능하도록 연계되어 구성된다.According to this need, a snow removal liquid tank is installed outside the road shoulder, a pump connected to the tank by an injection pipe is configured, and a spray nozzle connected to the pump by an injection pipe is configured. In addition, a communication unit is connected to the pump, and the communication unit is configured to be connected to an administrator's terminal to enable communication through an Internet network.
따라서, 관리자는 눈이 내리게 되면 도로 주변에 설치된 무인카메라를 통해서 도로의 상황을 확인한 후 상기 단말기를 통해서 상기 통신부로 전원을 인가하는 신호를 발신한다. 그러면, 상기 펌프에는 전원이 공급되면서 작동하게 되고, 상기 분사노즐을 통해서 제설액을 도로의 노면에 분사하므로 눈이 쌓여서 동결되기 전에 녹여서 노견으로 배수되도록 한다.Accordingly, when it snows, the manager checks the condition of the road through an unmanned camera installed around the road, and then transmits a signal for applying power to the communication unit through the terminal. Then, the pump is operated while power is supplied, and since the snow removal liquid is sprayed onto the road surface through the spray nozzle, it is melted before snow accumulates and freezes, so that it is drained to the shoulder.

That is, since the installation block 10 must be installed with the salt water spraying means 20, it is preferable that the installation block 10 is spaced apart from the road surface for driving the vehicle and installed in a nearby place.
도 1, 도 2 및 도 4에 도시된 바와 같이 본 발명에 따른 염수살포수단(20)은 혹한기나 동절기에 물이나 강설로 인하여 도로의 차단 이력이 있는 제설 취약구간이나, 상습 결빙구간에 염수를 살포하게 된다.As shown in FIGS. 1, 2 and 4, the salt water spraying means 20 according to the present invention sprays salt water in a weak snow removal section or a habitual freezing section with a history of blocking roads due to water or snowfall in cold or winter seasons. It will be sprayed.
이를 위해 염수살포수단(20)은 설치블록(10)에 설치되는데, 첨부된 도 1 및 도 2의 도시에서와 같이 설치블록(10) 후면에 염수공급관(21)을 설치하고, 염수공급관(21)로부터 분기하여 설치블록(10)을 관통하여 분사노즐(23)이 설치된다. 이 경우 염수공급관(21)으로부터 분기되는 분사노즐(23)을 일정한 간격으로 설치될 수 있고, 필요에 따라서는 상습 결빙구간에 집중적으로 염수가 살포될 수 있도록 분사노즐(23)을 배치하는 것도 가능하다.To this end, the salt water spraying means 20 is installed on the installation block 10, and a salt water supply pipe 21 is installed at the rear of the installation block 10 as shown in the accompanying drawings 1 and 2, and the salt water supply pipe 21 Branching from) and passing through the installation block 10, the injection nozzle 23 is installed. In this case, the spray nozzles 23 branching from the salt water supply pipe 21 can be installed at regular intervals, and if necessary, it is possible to arrange the spray nozzles 23 so that salt water can be intensively sprayed in the habitual freezing section. Do.
염수공급관(21)은 도 1 및 도 2의 도시와 같이 설치블록(10) 후면에 설치하는 것 이외에 첨부된 도면에는 도시되지 않았지만 설치블록(10)에 내장될 수 있도록 설치하는 것도 가능하다.The salt water supply pipe 21 is not shown in the accompanying drawings, in addition to being installed on the rear side of the installation block 10 as shown in FIGS. 1 and 2, but may be installed so as to be embedded in the installation block 10.
이와 같이 염수살포수단(20)은 전술한 바와 같이 혹한기나 동절기에 물이나 강설로 인하여 도로의 차단 이력이 있는 제설 취약구간이나, 상습 결빙구간에 설치하는데 이러한 구간들은 다음과 같은 구간이나 지역일 수 있다.As described above, the salt water spraying means 20 is installed in a weak snow removal section or a habitual freezing section that has a history of blocking roads due to water or snowfall in cold or winter seasons. These sections may be the following sections or regions. have.
즉 산악구간(터널, 교량, 입출구부) 및 하천입구구간 등 기온 변화가 크고 습도가 높은 노면결빙 취약지점이거나, 빙점, 서리, 안개 등에 의하여 기습노면 결빙이 예상되는 지역일 수 있다. 또한 분기점, 나들목, 지사간경계구간(사각지대) 등이나, 지정체로 인한 제삭작업차량의 현장 접근이 곤란한 장소 등일 수 있다. 이러한 지역이나 장소, 구간에 염수살포수단(20), 즉 염수살포시스템을 설치하는 경우 대응효과가 클 뿐만 아니라, 사고예방효과도 높일 수 있다.That is, it may be a location where the temperature change is large and humidity is high, such as a mountain section (tunnel, bridge, entrance/exit section) and a road surface freezing vulnerable to high humidity, or an area where surprise road surface freezing is expected due to freezing points, frost, fog, etc. In addition, it may be a branch point, a crossroads, a boundary section between branches (blind spots), or a place where it is difficult for a cutting vehicle to access the site due to a designated body. When a salt water spraying means 20, that is, a salt water spraying system is installed in such an area, place, or section, not only the response effect is large, but also the accident prevention effect can be increased.
도 1 내지 도 4에 도시된 바와 같이 본 발명에 따른 물감지부(30)는 동절기나, 혹한기에 눈이나, 물을 감지하게 된다. 이는 눈 또는 강설이 내리거나, 물, 즉 비가 내리게 되면 전술한 바와 같은 상습 결빙구간에서는 결빙의 위험이 커지게 되고, 이때 물감지부(30)가 결빙의 원인이 되는 눈이나, 물을 감지하여 감지된 신호를 컨트롤부(50)에 전송하게 된다.1 to 4, the water detecting unit 30 according to the present invention detects snow or water in winter or in cold weather. This is when snow or snowfall or water, that is, rain, increases the risk of freezing in the habitual freezing section as described above, and at this time, the water detection unit 30 detects and detects snow or water that causes freezing. The resulting signal is transmitted to the control unit 50.
이러한 물감지부(30)는 설치블록(10)이나, 도로 노면(1)에 설치가 가능한데, 첨부된 도 1 및 도 2의 도시에서는 설치블록(10) 상부에 설치되어 있으며, 이하 물감지부(30) 구성은 설치블록(10) 상부에 설치되는 것을 전제로 설명하겠으나, 도로 노면(1)에 설치되는 경우에도 특별한 사항이 아니면 동일한 구성으로 설치된다.Such a water detection unit 30 can be installed on the installation block 10 or on the road surface 1, but is installed on the installation block 10 in the accompanying drawings 1 and 2, and hereinafter, the water detection unit 30 ) The configuration will be described on the premise that it is installed on the top of the installation block 10, but even if it is installed on the road surface 1, it is installed in the same configuration unless there are special details.
먼저 물감지부(30)는 양단에 전원 공급을 위한 커넥터(32)가 구비되는 물감지센서(31)와, 물감지센서(31)를 덮는 센서커버(33)와, 물감지센서(31)의 커넥터(32)를 덮는 커넥터커버(34)와, 센서커버(33)의 측부에 형성되어 물감지센서(31)로 눈이나 물을 유입시키는 투입부(35)를 포함하여 구성된다. 또한 물감지부(30)를 덮기 위한 외함체(36)가 더 구비되고, 외함체(36)에는 눈이나 물이 상기 물감지센서(31)로 투입을 가능하게 하는 투입망(37)이 구비된다.First, the water detection unit 30 includes a water detection sensor 31 having connectors 32 for supplying power at both ends, a sensor cover 33 covering the water detection sensor 31, and a water detection sensor 31. A connector cover 34 covering the connector 32 and an input portion 35 formed on the side of the sensor cover 33 to introduce snow or water into the water detection sensor 31 are included. In addition, an enclosure body 36 for covering the water detection unit 30 is further provided, and the enclosure body 36 is provided with an input network 37 that allows snow or water to be injected into the water detection sensor 31. .
즉 물감지부(30)는 외부에 설치되어야 하므로 눈이나, 물과 접촉이 많을 뿐만 아니라, 먼지나 이물질 등의 침투로부터 물감지센서(31)를 보호하여야 센서의 민감도를 높일 수 있고, 외부로부터 공급되는 전원으로 인한 감전, 단선 등이나, 센서의 오작동 등을 막을 수 있다.That is, since the water detection unit 30 must be installed outside, not only has a lot of contact with snow or water, but also protects the water detection sensor 31 from penetration of dust or foreign substances, so that the sensitivity of the sensor can be increased and supplied from the outside. It can prevent electric shock, disconnection, etc. due to the power supply, or malfunction of the sensor.
따라서 상기한 바와 같은 물감지부(30)의 구성들은 이러한 목적을 구현하기 위한 것이다.Therefore, the configurations of the water sensing unit 30 as described above are for implementing this purpose.
물감지부(30)의 물감지센서(31)는 필름 형태의 센서를 사용하게 되고, 이러한 물감지센서(31)의 양단에는 외부 전원의 공급을 위한 커넥터(32)가 구비된다. 이렇게 구성되는 물감지센서(31)는 센서커버(33)에 의하여 덮이고, 물감지센서(31)의 커넥터(32)는 별도의 커넥터커버(34)에 의하여 덮인다. 이 경우 센서커버(33)와 커넥터커버(34)에는 양측으로 고정부가 형성되어 볼트나 피스 등의 고정구에 의하여 설치블록(10)이나, 도로 노면(1)에 장착된다.The water detection sensor 31 of the water detection unit 30 uses a film-type sensor, and connectors 32 for supplying external power are provided at both ends of the water detection sensor 31. The water detection sensor 31 configured in this way is covered by the sensor cover 33, and the connector 32 of the water detection sensor 31 is covered by a separate connector cover 34. In this case, fixing portions are formed on both sides of the sensor cover 33 and the connector cover 34, and are mounted on the installation block 10 or the road surface 1 by fasteners such as bolts or pieces.
이와 같이 구성되는 센서커버(33)와 커넥터커버(34)는 물감지센서(31)와 커넥터(32)를 덮어 먼지나 이물질 등의 침투를 방지하게 된다.The sensor cover 33 and the connector cover 34 configured as described above cover the water detection sensor 31 and the connector 32 to prevent penetration of dust or foreign substances.
이 경우 물감지센서(31)는 센서커버(33)에 의하여 덮여 있어 눈이나, 물과의 접촉이 어려울 수 있기 때문에 센서커버(33)의 양측면은 홈 형상을 절개된 투입부(35)가 구비되는 것이 바람직하다. 센서커버(33)의 투입부(35)는 여러 개소로 형성되어 눈이나 물이 투입부(35)를 통하여 물감지센서(31)와 접촉이 이루어질 수 있다.In this case, since the water detection sensor 31 is covered by the sensor cover 33 and it may be difficult to contact with snow or water, both sides of the sensor cover 33 are provided with input portions 35 having a groove shape cut off. It is desirable to be. The injection part 35 of the sensor cover 33 is formed in several places, so that snow or water may be brought into contact with the water detection sensor 31 through the injection part 35.
상기한 바와 같이 모듈화된 물감지부(30)는 전체적으로 외함체(36)에 의하여 덮이고, 이 외함체(36) 역시 설치블록(10)이나, 도로 노면(1)에 장착되는 구조로 구성된다. 이 경우 외함체(36)의 내측에는 눈이나, 물이 투과될 수 있도록 투입망(37)이 형성되고, 이 투입망(37)은 통하여 눈이나 물이 물감지센서(31)로 유입될 수 있다.As described above, the modularized water detection unit 30 is entirely covered by the enclosure body 36, and the enclosure body 36 is also configured to be mounted on the installation block 10 or the road surface 1. In this case, an input net 37 is formed inside the enclosure 36 so that snow or water can pass through, and through this input net 37, snow or water can flow into the water detection sensor 31. have.
상기한 바와 같이 물감지부(30)는 모듈화되어 있을 뿐만 아니라, 혹한이나 동절기 등와 같이 극한 환경에서 설치되는 특성상 보호구조를 구현하고 있고, 보호구조에 동시에 눈이나 물의 유입을 원활히 할 수 있는 구조를 도입함으로서 장치의 내구성, 작동신뢰성 등을 보장하고 도모할 수 있다.As described above, the water detection unit 30 is not only modular, but also implements a protection structure due to the nature of being installed in extreme environments such as cold or winter, and a structure that can smoothly inflow of snow or water at the same time is introduced into the protection structure. As a result, durability and operational reliability of the device can be guaranteed and promoted.
도 1, 도 2 및 도 4에 도시된 바와 같이 본 발명에 따른 온도감지부(40)는 도로 노면(1) 상에 설치되어 도로 노면(1)의 온도를 감지하고, 감지된 신호를 컨트롤부(50)에 전송하게 된다.1, 2 and 4, the temperature sensing unit 40 according to the present invention is installed on the road surface 1 to detect the temperature of the road surface 1, and control the detected signal. Will be sent to (50).
온도감지부(40)는 도로 노면(1)의 일측부에 매설되는 형태로 설치되어 도로 노면(1)의 온도를 감지하게 된다. 이 경우 온도감지부(40)는 전술한 바와 같이 상습 결빙구간에 인접하게 하도록 설치하는 것이 바람직하다. 따라서 온도감지부(40)는 상습 결빙구간의 온도를 감지하여 컨트롤부(50)에 전송하게 된다. 이 경우 컨트롤부(50)는 상습 결빙구간의 온도가 어는점 온도인 영하 이하인 경우 염수살포수단(20)을 작동시켜 분사노즐(23)에 의하여 염수가 상습 결빙구간으로 살포될 수 있도록 제어하게 된다.The temperature sensing unit 40 is installed in a form embedded in one side of the road surface 1 to sense the temperature of the road surface 1. In this case, it is preferable that the temperature sensing unit 40 be installed so as to be adjacent to the humidity freezing section as described above. Accordingly, the temperature sensing unit 40 senses the temperature of the freezing zone and transmits it to the control unit 50. In this case, the control unit 50 operates the salt water spraying means 20 when the temperature of the freezing point temperature is below zero, which is the freezing point temperature, so that the salt water can be sprayed into the humidity freezing zone by the spray nozzle 23.
즉 상습 결빙구간에서 감지된 온도에 따른 염수살포수단(20)의 동작 여부는 컨트롤부(50)에서 설정된 온도에 의하여 결정되겠으나, 통상적으로 어는점 온도인 영하 이하의 온도가 설정온도가 될 수 있다. 다만 설정온도는 영상인 경우에도 가능한데, 이 경우에는 상습 결빙구간의 감지온도가 영하에 근접한 영상인 경우에도 결빙이 발생하기 전에 선제적으로 염수를 살포할 수 있기 때문이다.That is, whether or not the salt water spraying means 20 operates according to the temperature sensed in the humidity freezing section will be determined by the temperature set by the control unit 50, but a temperature below zero, which is a freezing point temperature, may be the set temperature. . However, the set temperature is also possible in the case of an image, because in this case, even if the detected temperature in the normal freezing section is close to below zero, salt water can be preemptively sprayed before freezing occurs.
전술한 바와 같이 구성되는 염수살포수단(20)의 제어는 도 4의 도시와 같이 컨트롤부(50)에 의하여 제어되는데, 이하에서 도 4의 개통도를 참조하여 제어방법을 기술하기로 한다.The control of the salt water spraying means 20 configured as described above is controlled by the control unit 50 as shown in FIG. 4. Hereinafter, a control method will be described with reference to the opening diagram of FIG. 4.
도 4의 도시와 같이 컨트롤부(50)는 물감지부(30)와 온도감지부(40)에 의한 감지신호를 전송받게 된다. 이 경우 컨트롤부(50)는 관제센터에 구비되어 원격지 제어를 할 수 있을 뿐만 아니라, 유무선 통신을 이용하여 관리자가 소지한 단말기 등으로 제어가 가능하다 할 것이다.As shown in FIG. 4, the control unit 50 receives a detection signal by the water detection unit 30 and the temperature detection unit 40. In this case, the control unit 50 may be provided in the control center to perform remote control as well as control with a terminal possessed by an administrator using wired or wireless communication.
이렇게 컨트롤부(50)에서는 혹한기 및 동절기에 눈이나, 비가 오는 경우 이를 감지하여 감지신호를 수신하게 되고, 이렇게 눈이나 비가 감지되면 컨트롤부(50)에서는 온도감지부(40)에 의하여 감지된 상습 결빙구간의 온도를 수신하게 된다. 상습 결빙구간에서 감지된 온도가 설정온도 이하인 경우 컨트롤부(50)는 염수가 저장된 탱크에서 펌프(P)를 가동시키게 된다. 이렇게 펌프(P)에 의하여 공급되는 염수는 컨트롤밸브(CV)에 의하여 염수공급관(21)으로 공급된다. 이때 컨트롤부(50)는 컨트롤밸브(CV)의 개도를 조절하여 염수의 공급량을 조절할 수 있다. 이렇게 공급된 염수는 염수공급관(21)과 분사노즐(23)을 통하여 상습 결빙구간으로 염수를 살포하게 되고, 살포된 염수에 의하여 상습 결빙구간의 노면은 해빙될 수 있다.In this way, the control unit 50 detects snow or rain in cold and winter seasons and receives a detection signal, and when snow or rain is detected, the control unit 50 receives the normal humidity detected by the temperature detection unit 40. It receives the temperature of the freezing section. When the temperature sensed in the normal freezing section is below the set temperature, the control unit 50 operates the pump P in the tank in which the salt water is stored. In this way, the brine supplied by the pump P is supplied to the brine supply pipe 21 by the control valve CV. At this time, the control unit 50 may adjust the supply amount of salt water by adjusting the opening degree of the control valve CV. The brine supplied in this way is sprayed with brine through the brine supply pipe 21 and the spray nozzle 23 to the habitual freezing section, and the road surface of the habitual freezing section may be thawed by the sprayed brine.
이 경우 컨트롤부(50)는 상습 결빙구간의 노면이 해빙되면 컨트롤밸브(CV)를 폐쇄하여 염수 공급을 차단하게 되는데, 이는 온도감지부(40)가 연속적으로 상습 결빙구간의 온도를 감지하게 되므로 상습 결빙구간에서 감지된 온도가 설정온도 이상으로 감지되는 경우 컨트롤밸브(CV)를 폐쇄하여 염수의 공급을 차단하거나, 또는 설정온도 이하에서 각 온도 마다 주변의 온도를 참조하여 염수 공급시간에 따른 해빙시간을 미리 설정하는 두는 것도 가능하다.In this case, the control unit 50 shuts off the supply of salt water by closing the control valve (CV) when the road surface of the humid freezing section is thawed. This is because the temperature sensing unit 40 continuously senses the temperature of the humid freezing section. If the temperature detected in the humidity freezing section is higher than the set temperature, the control valve (CV) is closed to block the supply of salt water, or thawing according to the salt water supply time by referring to the surrounding temperature at each temperature below the set temperature. It is also possible to set the time in advance.
이와 같이 본 발명에 따른 염수살포시스템은 상습 결빙구간에 염수를 살포하고, 이를 통하여 교통사고나 또는 이러한 위험 방지를 위한 교통 차단 등의 사태를 방지할 수 있다. 이는 교통사고를 선제적으로 대응함으로써 초기대응 재난 관리시스템의 구현을 가능하게 한다.As described above, the salt water spraying system according to the present invention sprays salt water in the habitual freezing section, and through this, it is possible to prevent accidents such as traffic accidents or traffic blocking to prevent such dangers. This makes it possible to implement an initial response disaster management system by proactively responding to traffic accidents.
이와 같이 본 발명은 도면에 도시된 일실시례를 참고로 설명되었으나, 이는 예시적인 것에 불과하며, 본 기술 분야의 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시례가 가능하다는 점을 이해할 것이다.As described above, the present invention has been described with reference to one embodiment shown in the drawings, but this is only exemplary, and various modifications and other equivalent embodiments are possible from those of ordinary skill in the art.
