설명하지 않은 도면번호 13은 상기 측량관체(10)의 수직관부(12) 상단에 구비되어 빗물 등이 수직관부(12)의 개구부(12a)를 통해 내부로 유입되는 것을 방지하는 커버를 도시한 것이며, 도면번호 60은 상기 제어유닛(40)에 연결된 배터리를 도시한 것이다.Reference numeral 13 which is not described shows a cover provided at the upper end of the vertical pipe part 12 of the survey pipe 10 to prevent rainwater from entering the interior through the opening 12a of the vertical pipe part 12. Reference numeral 60 shows a battery connected to the control unit 40.

이와 같이 구성된 수준측량시스템의 작용을 설명하면 다음과 같다.The operation of the leveling system configured as described above is as follows.

우선, 작업자가 상기 수평관부(11) 양단이 교량 상판(2)의 폭방향 좌우단에 근접되도록 상기 측량관체(10)를 교량에 고정설치하고, 수직관부(12) 상단의 개구부(12a)를 통해 측량관체(10)의 내부에 유체를 주입한다. 이때, 상기 유체는 상기 수위측정기구(20)의 플로터(23)가 일정수준 상측으로 떠오를 때까지 주입된다.First, the worker fixedly installs the survey pipe 10 on the bridge so that both ends of the horizontal pipe 11 are close to the left and right ends in the width direction of the bridge top plate 2, and the opening 12a at the upper end of the vertical pipe 12 is opened. The fluid is injected into the inside of the survey pipe (10). At this time, the fluid is injected until the floater 23 of the water level measuring instrument 20 rises above a certain level.

그리고, 작업자가 상기 제어유닛(40)을 on 시키면, 수위측정기구(20)에 의해 측정된 수위변화량 데이터와, 압력센서(30)에 의해 측정된 압력 값을 제어유닛(40)이 각각 수신받아 상판(2)의 양단에 상대높이 변화량을 계산하고, 계산된 상판(2) 양단의 상대높이 변화량 데이터를 상기 무선송신기(50)를 통해 무선송신하여, 작업자가 무선송신기(50)를 통해 송신된 상판(2) 양단의 상대높이 변화량 데이터를 수신하여, 상판(2)의 비틀림을 실시간으로 감시할 수 있다.When the operator turns on the control unit 40, the control unit 40 receives the level change amount data measured by the level measuring instrument 20 and the pressure value measured by the pressure sensor 30, respectively. The relative height change amount is calculated at both ends of the upper plate 2, and the calculated relative height change amount data at both ends of the upper plate 2 are wirelessly transmitted through the wireless transmitter 50, so that the operator transmits the wireless transmitter 50 through the wireless transmitter 50. By receiving the relative height change amount data of both ends of the upper plate 2, the torsion of the upper plate 2 can be monitored in real time.

즉, 상기 측량관체(10)는 일단이 밀폐되고, 타단은 상측으로 연장되어 상단이 개방되어, 측량관체(10)의 우측 밀폐단(11a)에 구비된 압력센서(30)에는 대기압과 측량관체(10)의 내부에 주입된 유체의 압력이 작용되므로, 상기 압력센서(30)에 작용되는 유체의 압력은 상기 유체의 수면으로부터 상기 압력센서(30)의 설치위치까지의 수직방향 거리에 비례하게 된다. 따라서, 상기 상판(2)이 비틀려 상판(2)의 폭방향 양단의 상대높이가 달라질 경우, 도 4의 (a)와 (b)에 도시한 바와 같이, 상기 측량관체(10) 역시 상판(2)의 비틀림에 따라 좌측 또는 우측방향으로 기울어지면서 수면과 압력센서(30)의 수직방향거리(L1,L2)가 변하게 되며, 이에따라 압력센서(30)에 작용되는 압력이 변동된다. That is, one end of the measurement pipe 10 is closed, the other end is extended to the upper end is open, the pressure sensor 30 provided at the right closed end (11a) of the measurement pipe 10 to the atmospheric pressure and the measurement pipe Since the pressure of the fluid injected into the inside of the 10 is applied, the pressure of the fluid acting on the pressure sensor 30 is proportional to the vertical distance from the surface of the fluid to the installation position of the pressure sensor 30. do. Therefore, when the top plate 2 is twisted and the relative heights of both ends in the width direction of the top plate 2 are changed, as shown in FIGS. 4A and 4B, the surveying body 10 also has a top plate ( According to the twist of 2) the vertical distance (L1, L2) of the water surface and the pressure sensor 30 is inclined in the left or right direction, and the pressure applied to the pressure sensor 30 is changed accordingly.

따라서. 상기 제어유닛(40)이 상기 압력센서(30)에 의해 측정되어 출력되는 압력측정값의 변화량을 계산하여, 간접적으로, 상기 상판(2) 양단의 상대높이 변화량을 계산하고, 계산된 상판(2) 양단의 상대높이 변화량을 디지털 데이터로 변환하여 상기 무선송신기(50)를 통해 무선송신할 수 있으며, 작업자는 무선송신된 데이터를 수신하여 상판(2)의 비틀림 정도를 실시간으로 감시할 수 있다. 이때, 수평관부(11)가 길고 수직관부(12)가 짧을수록 상기 압력센서(30)를 이용하여 상판(2) 양단의 상대높이 변화량을 정확히 측정할 수 있으므로, 상기 수평관부(11)는 상판(2)의 폭방향 길이에 최대한 가깝게 구성하고, 상기 수직관부(12)는 상단부가 상기 상판(2)의 상측으로 돌출될 정도로만 짧게 구성하는 것이 바람직하다.therefore. The control unit 40 calculates the change amount of the pressure measurement value measured and output by the pressure sensor 30, and indirectly, calculates the change in the relative height of both ends of the top plate 2, and calculates the calculated top plate 2 ) The relative height change amount at both ends can be converted into digital data and wirelessly transmitted through the wireless transmitter 50. An operator can monitor the twist degree of the upper plate 2 in real time by receiving the wirelessly transmitted data. In this case, as the horizontal pipe portion 11 is longer and the vertical pipe portion 12 is shorter, since the relative height variation of both ends of the upper plate 2 can be accurately measured using the pressure sensor 30, the horizontal pipe portion 11 is a top plate. It is preferable to comprise as close as possible to the width direction length of (2), and to configure the said vertical pipe part 12 only so short that an upper end part protrudes to the upper side of the said upper plate 2.

또한, 상기 측량관체(10)의 수직관부(11) 상단은 대기압이 상기 유체에 작용될 수 있도록 개방되어 있으므로, 측량관체(10) 내부의 유체가 증발되어 유체의 양에 변동이 발생될 수 있다. 따라서, 상기 제어유닛(40)은 상기 수위측정기구(20)를 이용하여 측량관체(10)에 저장된 유체의 수위변화를 측정하고, 이와같이 측정된 유체의 수위변화량에 따른 압력변화량을 가감하여, 순수하게 상기 상판(2)의 비틀림에 의해 측량관체(10)가 기울어짐에 따른 압력변화를 연산할 수 있다. 그리고, 유체가 많이 증발되어 수위가 지나치게 낮아질 경우, 상기 제어유닛(40)은 경보신호를 출력하여, 작업자가 측량관체(10)의 내부에 유체를 보충하도록 하는 것도 가능하다.In addition, since the upper end of the vertical pipe portion 11 of the survey pipe 10 is open so that atmospheric pressure can be applied to the fluid, the fluid inside the survey pipe 10 may be evaporated, causing variations in the amount of fluid. . Therefore, the control unit 40 measures the change in the level of the fluid stored in the survey pipe 10 by using the level measuring device 20, and subtracts the amount of pressure change in accordance with the measured level of the fluid, thereby purifying pure water. By the twist of the upper plate 2 it is possible to calculate the pressure change according to the surveying pipe 10 is tilted. In addition, when the fluid is much evaporated and the water level becomes too low, the control unit 40 may output an alarm signal to allow the worker to replenish the fluid inside the survey pipe 10.

이와같이 구성된 수준측량시스템은 상판(2)에 설치된 측량관체(10)가 상판(2)에 고정설치되어, 상판(2)이 비틀릴 때 상기 측량관체(10)가 함께 기울어짐에 따라 내부의 압력이 변화되는 것을 감지하여, 간접적으로 상판(2)의 비틀림을 감지하므로, 상판(2)의 비틀림을 실시간으로 감시할 수 있는 장점이 있다.The leveling system configured as described above has a measurement pipe 10 installed on the top plate 2 fixedly mounted on the top plate 2, so that when the top plate 2 is twisted, the measurement pipe 10 is inclined together and the internal pressure is increased. By detecting this change, indirectly detects the torsion of the upper plate 2, there is an advantage that can be monitored in real time the torsion of the upper plate (2).

또한, 이러한 수준측량시스템은 측량관체(10)에 압력센서(30)와 수위측정기구(20)를 설치하여 구성되므로, 구조가 간단하고, 유지보수가 용이하며, 코스트를 절감할 수 있는 장점이 있다.In addition, since the level measurement system is configured by installing the pressure sensor 30 and the water level measuring mechanism 20 in the survey pipe 10, the structure is simple, easy to maintain, and has the advantage of reducing the cost have.

특히, 상기 수준측량시스템은 측량관체(10) 내부에 주입된 유체에 의해 압력센서(30)에 작용되는 압력을 실시간으로 측정하므로, 차량의 주행에 의해 발생되는 진동등에 의한 외부영향을 최소화할 수 있는 장점이 있다.In particular, the level measurement system measures in real time the pressure acting on the pressure sensor 30 by the fluid injected into the survey pipe 10, thereby minimizing external influences due to vibrations generated by driving of the vehicle. There is an advantage.

본 실시예의 경우, 상기 수위측정기구(20)는 측량관체(10) 내부의 수면에 떠있는 플로터(23)에 연결된 회동아암(22)의 각도를 측정하여, 수위의 변화를 감지할 수 있도록 구성되었으나, 수위측정기구(20)는 측량관체(10) 내부의 유체의 수위를 측정할 수 있는 것은 어떠한 것도 사용될 수 있다.In the present embodiment, the water level measuring instrument 20 is configured to measure the angle of the rotating arm 22 connected to the floater 23 floating on the water surface inside the survey pipe 10, so as to detect a change in the water level. However, the water level measuring instrument 20 can be used anything that can measure the level of the fluid inside the measurement pipe 10.
