Description

[규칙 제26조에 의한 보정]　유속 및 유량 측정장치와 이를 이용한 측정시스템[Correction according to Rule 26] Flow rate and flow measuring device and measuring system
본 발명은 수공학 분야에 관한 것으로서, 상세하게는, 하천의 유속 및 유량을 측정하기 위한 장치에 관한 것이다.TECHNICAL FIELD This invention relates to the field of hydraulic engineering. Specifically, It is related with the apparatus for measuring the flow velocity and flow volume of a river.
하천의 유량자료는 이수, 치수, 수질관리 등의 목적으로 널리 사용되기 때문에 여러 가지 수문관측 자료 중 가장 중요하다.River flow data is the most important of the various hydrologic observation data because it is widely used for water, water and water quality management.
그러나 측정되는 유량자료는 여러 가지 한계를 가지고 있어서 수문자료로서 제대로 사용되지 못하고 있는 실정이다.However, the measured flow rate data have various limitations and are not properly used as hydrologic data.
특히 홍수기 부자측정 방법에 의해 산정된 유량자료는 측정 여건, 방법, 기기 등의 한계로 인해 그 정확도가 더욱 낮다.In particular, the flow rate data calculated by the flood rich measurement method is less accurate due to the limitations of measurement conditions, methods, and equipment.
전통적인 유량측정 방법은 유속계를 이용해서 측정된 유속과 단면측량에 의해 계산된 흐름 단면적의 곱으로 유량을 계산하는 것이다.Traditional flow measurement methods use a flowmeter to calculate the flow rate as the product of the flow cross-sectional area calculated by the flow rate measured by the cross-sectional measurement.
유속계에 의한 유속측정 방법은 비교적 유속 규모가 작고, 측정 여건이 양호한 평·저수기에 사용된다.The flow rate measurement method using a flow meter is used in flat and water reservoirs with a relatively small flow rate scale and good measurement conditions.
반면 흐름이 급격하게 변하고, 빠른 유속 및 부유 잡물에 의해 유속계를 이용한 측정이 곤란한 홍수기에는 부자법에 의한 유량측정을 시행하고 있다.On the other hand, in the flood season where the flow changes drastically, and the flow rate is difficult to measure due to the high flow rate and the suspended matter, the flow rate measurement by the rich method is performed.
도 1,2에 도시된 바와 같이, 부자에 의한 유량측정은 다수의 부자(10)를 각각 구분단면을 따라 하천에 투하하고, 일정거리(11과 12 사이)를 유하하는 부자의 유하시간을 측정하여 평균유속을 구하고, 사전에 측량된 횡단면으로부터 유하한 개별 부자의 해당 단면적을 구하여 부분 단면적을 구한다.As shown in Figures 1 and 2, the flow rate measurement by the rich drops a number of rich 10 to the river along the section, respectively, measuring the flow time of the rich to flow a certain distance (between 11 and 12) The average flow rate is obtained, and the corresponding cross-sectional area of each rich man descending from the previously measured cross section is obtained to determine the partial cross-sectional area.
구해진 개별 부자의 평균유속과 부분 단면적을 곱하여 부분유량을 산출한 후, 각 부분유량을 합하여 전체 유량을 계산한다.After calculating the partial flow rate by multiplying the average flow rate and the partial cross-sectional area of the individual rich, the total flow rate is calculated by summing each partial flow rate.
이와 같은 부자법은 유속-면적법이 가지고 있는 흐름 단면적 계산, 평균유속 계산 오차 이외에 유하경로에 따른 오차, 부자 유하 시간 측정 오차, 유속 보정 계수에 따른 오차 등을 포함한다.Such a rich method includes the flow cross-sectional area calculation, the average flow velocity calculation error, the flow path error, the rich flow time measurement error, and the flow rate correction coefficient.
기존 홍수 유량측정에 사용하고 있는 부자법은 육안에 의해 부자의 위치를 파악하고, 가상의 시준선을 통과할 때 육안으로 관측하여 유하시간을 측정하는 방법이기 때문에 정확한 유량측정에 한계가 있으며, 부자가 하천을 따라 직진한다는 전제로 유량을 계산하지만 실제로는 흐름에 따라 경사지게 이동하는 경우가 많기 때문에 매우 큰 오차가 발생한다. The rich method, which is used for the existing flood flow measurement, is a method of determining the location of the rich man with the naked eye and observing the naked eye as it passes through the virtual collimator to measure the descent time. The flow rate is calculated on the premise that it goes straight along the stream, but in practice it tends to move very obliquely along the flow, resulting in very large errors.
뿐만 아니라 측정에 다수의 인원이 필요하며, 홍수시 많은 비가 내리거나, 야간에 측정하는 경우에는 부자의 식별이 곤란하고 측정 여건이 불량해 측정에 큰 애로가 있다.In addition, a large number of personnel are required for measurement, and when there is a lot of rain during flooding or measurement at night, the identification of the rich is difficult and the measurement conditions are poor.
본 발명은 기존의 홍수기 유속 및 유량 측정 장치나 방법에 한계로 작용하였던 여러 가지 문제점들, 즉 인력에 의한 육안 관측으로 인한 큰 오차가 발생하였던 점, 부자가 시준선을 통과할 때 통과하는 시점을 측정하는데 다수의 인원이 필요하였던 점, 다수의 부자를 개별적으로 투하하여 유하하는 시간을 측정함에 따라 장시간의 측정시간이 소요된 점, 우천, 야간 등의 측정에 있어 육안 관측의 어려움으로 측정에 오차가 크게 발생하였던 점, 부자가 하류 방향으로 직진하지 않은 조건에서 부자 위치를 부정확하게 측정함에 따라 유속 및 유량측정에 큰 오차를 발생시킨 점 등을 개선하여, 홍수기와 같이 흐름이 급하게 변하고, 빠른 유속이 존재하는 조건이라 하더라도 측정오차를 최소화하면서 측정할 수 있도록 하는 유속 및 유량 측정장치와 이를 이용한 측정시스템을 제시하는 것을 그 목적으로 한다.The present invention measures a number of problems that have been a limitation to the existing apparatus and method for measuring the flow rate and flow rate of a flood, that is, a large error occurred due to visual observation by manpower, and a time point when a rich person passes through a collimation line. In order to measure the time required for a large number of people, the time of dropping a large number of individuals individually, the measurement time was long, and the measurement error was difficult due to the difficulty of visual observation. Improved the occurrence of large error and the fact that the position of the rich was inaccurately measured under the condition that the rich did not go in the downstream direction, and caused a large error in the flow rate and the flow rate measurement. Flow rate and flow measuring devices that can be measured with minimal measurement errors, even under existing conditions And to present the yonghan measuring system for that purpose.

이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 3 이하에 도시된 바와 같이, 본 발명에 의한 유속 및 유량 측정장치(100)는 기본적으로, 하천 위에 떠서 하천의 수체와 함께 거동하는 부자 본체(110); GPS 위치정보를 수신하도록, 부자 본체(110)에 장착된 GPS 수신부(120); 수신된 GPS 위치정보 및 측정 시간을 송신하도록, 부자 본체(110)에 장착된 위치 및 시간정보 송신부(130);를 포함하여 구성된다.As shown below in Figure 3, the flow rate and flow rate measuring apparatus 100 according to the present invention is basically a rich body 110 that floats above the river and behaves with the body of the river; A GPS receiver 120 mounted to the rich main body 110 to receive GPS position information; And position and time information transmitter 130 mounted on the rich main body 110 to transmit the received GPS position information and measurement time.
이에 의해 송신된 정보를 수신하고, 유속 및 유량을 연산하기 위한 측정시스템은, 위치 및 시간정보 송신부(130)로부터 송신된 상기 GPS 위치정보 및 측정 시간을 수신하는 위치 및 시간정보 수신부(200); 위치 및 시간정보 수신부(200)에 의해 수신된 정보를 종합하여, 하천의 유속 및 유량을 연산하는 연산부(300);를 포함하여 구성된다.The measurement system for receiving the information transmitted by this, and for calculating the flow rate and flow rate, the position and time information receiver 200 for receiving the GPS position information and the measurement time transmitted from the position and time information transmitter 130; And a calculation unit 300 for calculating the flow rate and the flow rate of the river by combining the information received by the position and time information receiving unit 200.
즉, 도 5에 도시된 바와 같이, GPS 수신부(120)에 의해 수시된 측정장치(100)의 위치정보와 측정 시간이 송신부(130)에 의해 송신되면, 송신된 정보를 하천 부근에 설치된 본부에서 수신부(200)에 의해 수신하고, 연산부(300)에 의해 유속 및 유량의 즉시 연산이 가능하게 된다.That is, as shown in FIG. 5, when the position information and the measurement time of the measuring device 100 received by the GPS receiver 120 are transmitted by the transmitter 130, the transmitted information is transmitted from the headquarters installed near the river. Received by the receiving unit 200, it is possible to immediately calculate the flow rate and flow rate by the calculating unit 300.
따라서 종래 육안 관측에 의존하던 경우에 비해 오차의 발생을 대폭 줄일 수 있다는 점, 측정 작업을 위해 다수의 인원이 필요 없다는 점, 다수의 부자를 투하하는 경우라도 측정작업을 동시에 진행할 수 있으므로 작업시간이 단축된다는 점, 우천시, 야간시에도 정확한 측정이 가능하다는 점, 부자가 하류 방향으로 직진하지 않은 조건이더라도 부자 위치의 정확한 측정이 가능하다는 점, 홍수기와 같이 흐름이 급하게 변하고 빠른 유속이 존재하는 조건이라 하더라도 측정오차를 최소화할 수 있다는 점 등의 효과를 얻을 수 있다.Therefore, it is possible to greatly reduce the occurrence of error compared to the case of relying on the conventional visual observation, the fact that a large number of people are not required for the measurement work, and the measurement work can be performed at the same time even when a large number of rich people are dropped. It is shortened, it is possible to measure precisely even in rainy weather and at night, it is possible to measure the position of the rich even when the rich man is not going straight downstream. Even if the measurement error is minimized, the effect can be obtained.
이하, 본 발명에 의한 유속 및 유량 측정장치(100)의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the flow rate and flow rate measuring apparatus 100 according to the present invention will be described in detail.
유속 및 유량 측정장치(100)가 하천 위에서 자유로이 부유하도록 하기 위해서는, 부자 본체(110)는 막대 형상으로 형성되는 것이 바람직하다.In order to allow the flow rate and flow rate measuring device 100 to float freely on the river, the rich main body 110 is preferably formed in a rod shape.
이 경우, GPS 수신부(120)와 위치 및 시간정보 송신부(130)가 하천에 잠겨 전파 송수신 장애가 발생하는 것을 방지하기 위해서는, GPS 수신부(120), 위치 및 시간정보 송신부(130)가 부자 본체(110)의 두부에 장착되는 것이 바람직하다.In this case, in order to prevent the GPS receiver 120 and the location and time information transmitter 130 from being locked in a river and generating a radio wave transmission / reception failure, the GPS receiver 120, the location and time information transmitter 130 may be rich body 110. Is preferably mounted on the head.
또한, 이와 같은 부자 본체(110)의 두부가 항상 상측을 향하도록 하기 위해서는, 부자 본체(110)의 하부에 타 부위에 비해 중량이 크도록 중량부(140)가 장착되는 것이 바람직하다.In addition, in order for the head of the rich main body 110 to always face upward, the weight part 140 is preferably mounted on the lower part of the rich main body 110 so as to have a greater weight than other parts.
이러한 중량부(140)는 도 4에 도시된 바와 같이, 모래 등의 중량물이 수납되는 중량물 수납부(141); 중량물 수납부(141)를 개폐하는 뚜껑 등의 개폐부(142);를 포함하는 구성 등에 의해 구현될 수 있다.As shown in FIG. 4, the weight part 140 may include a weight storage part 141 in which heavy materials such as sand are stored; It may be implemented by a configuration including a; opening and closing portion 142, such as a lid for opening and closing the heavy material storage portion 141.
본 발명에 의한 유속 및 유량 측정장치(100)는 GPS 수신부(120)를 구비함으로써, 부자 본체(110)의 위치정보를 GPS에 의해 얻도록 하고 있는데, 이는 본 발명에 의한 장치가 적용될 하천은 열린 공간이므로 정확한 GPS 위치정보를 수신함에 제약이 거의 없기 때문이다.The flow rate and flow rate measuring apparatus 100 according to the present invention includes a GPS receiver 120 so that the position information of the rich main body 110 can be obtained by GPS, which is a stream to which the apparatus according to the present invention is opened. This is because there is almost no limitation in receiving accurate GPS location information because it is space.
위치 및 시간정보 송신부(130)는 측정장치(100)의 위치 및 측정시간에 관한 정보를 위치 및 시간정보 수신부(200)로 송신할 수 있는 구성이면, 어느 것을 취하더라도 관계없으며, 일반적인 RF 송신기를 포함하는 구성에 의해서도 구현될 수 있다.The position and time information transmitter 130 may transmit any information about the position and the measurement time of the measurement apparatus 100 to the position and time information receiver 200. It can also be implemented by a configuration that includes.
다만, 우천이나 하천의 너울에 의한 통신장애를 최소화하기 위해서는, 400 ~ 440 MHz 대역의 RF 통신 대역을 사용하는 것이 바람직한 것으로 확인되었다.However, in order to minimize communication obstacles caused by rain or rain, it is confirmed that it is desirable to use an RF communication band of 400 to 440 MHz band.
이러한 RF 송신기의 안테나(131)는, 상술한 위치 및 시간정보 송신부(130)가 부자 본체(110)의 두부에 위치하는 것이 바람직한 이유와 같이, 부자 본체(110)의 두부로부터 상측으로 돌출되도록 설치된 구조를 취하는 것이 바람직하다.The antenna 131 of the RF transmitter is installed to protrude upward from the head of the rich main body 110, such that the above-described position and time information transmitter 130 is preferably located on the head of the rich main body 110. It is desirable to take the structure.
이하, 상기 측정장치(100)를 포함하는 유속 및 유량 측정시스템의 실시예에 관하여 설명한다.Hereinafter, an embodiment of a flow rate and flow rate measuring system including the measuring device 100 will be described.
본 발명에 의한 유속 및 유량 측정시스템은 도 5에 도시된 바와 같이 기본적으로, 상술한 바와 같은 측정장치(100), 위치 및 시간정보 송신부(130)로부터 송신된 GPS 위치정보 및 측정 시간을 수신하는 위치 및 시간정보 수신부(200); 위치 및 시간정보 수신부(200)에 의해 수신된 정보를 종합하여, 하천의 유속 및 유량을 연산하는 연산부(300);를 포함하여 구성된다.The flow rate and flow rate measurement system according to the present invention basically receives the GPS position information and the measurement time transmitted from the measuring apparatus 100, the position and time information transmitter 130 as described above, as shown in FIG. Location and time information receiving unit 200; And a calculation unit 300 for calculating the flow rate and the flow rate of the river by combining the information received by the position and time information receiving unit 200.
하천의 유속은 위 측정장치(100)의 GPS 위치정보와 측정 시간 정보에 의해 구할 수 있고, 하천의 유량은 위 하천의 유속에 하천의 단면적을 곱함으로써 구할 수 있다.The flow velocity of the stream can be obtained by GPS position information and measurement time information of the measuring device 100, and the flow rate of the stream can be obtained by multiplying the flow rate of the stream by the cross-sectional area of the stream.
본 발명에 의한 측정시스템은 열린 공간인 하천을 대상으로 하므로, GPS 위치정보의 오차가 거의 발생하지 않지만, 더욱 정확한 측정값을 얻기 위해서는, 측정장치(100)의 GPS 수신부(120)와 별도로, 하천 부근에 설치되는 본부에 보정용 GPS 위치정보를 수신하는 보정용 GPS 수신부(400)를 설치하고, 이러한 보정용 GPS 위치정보에 의해 측정장치(100)의 위치 및 시간정보 수신부(200)에 의해 수신된 위치정보를 보정하도록 하는 것이 더욱 바람직하다.Since the measurement system according to the present invention targets the river which is an open space, the error of the GPS position information hardly occurs, but in order to obtain a more accurate measurement value, separately from the GPS receiver 120 of the measurement apparatus 100, the river A correction GPS receiver 400 for receiving the GPS position information for correction is installed at the headquarters installed in the vicinity, and the position information received by the position and time information receiver 200 of the measuring device 100 by the correction GPS position information. It is more preferable to make correction.
하천의 유속 및 유량은 동일 단면 내에서도 심부, 가장자리부에 따라 다르게 측정될 수 있는데, 이러한 조건을 모두 반영하여 더욱 정확한 측정값을 얻기 위해서는, 도 6,7에 도시된 바와 같이 복수의 측정장치(100)를 이용한 시스템을 적용하는 것이 바람직하다.The flow velocity and the flow rate of the river can be measured differently according to the core and the edge portion even in the same cross section. To obtain more accurate measurement values by reflecting all of these conditions, as shown in FIGS. It is desirable to apply a system using
즉, 도 7과 같이 복수의 측정장치(100a, 100b, 100c, 100d)가 하천의 다수 경로를 통해 흘러가도록 하고, 이들 각각으로부터 위치 및 시간정보를 수신받아, 각 경로의 유속 및 유량을 측정함으로써, 하천의 전체적 거동을 더욱 정확히 파악할 수 있는 것이다.That is, as shown in FIG. 7 by allowing a plurality of measuring devices 100a, 100b, 100c, and 100d to flow through a plurality of paths in a river, receiving position and time information from each of them, and measuring flow velocity and flow rate of each path. For example, it is possible to more accurately understand the overall behavior of rivers.
다만, 이 경우 각 측정장치로부터 송신되는 전파 상호의 혼선을 방지하기 위해서는, 복수의 유속 및 유량 측정장치(100a, 100b, 100c, 100d)의 위치 및 시간정보 송신부(130a, 130b, 130c, 130d)는 각각 상이한 통신 대역을 사용하도록 하고, 위치 및 시간정보 수신부(200)는 복수의 유속 및 유량 측정장치(100a, 100b, 100c, 100d)의 위치 및 시간정보 송신부(130a, 130b, 130c, 130d) 각각의 통신 대역의 전파를 수신하도록 다채널 구조로서 형성하는 것이 바람직하다.In this case, however, the position and time information transmitters 130a, 130b, 130c, and 130d of the plurality of flow velocity and flow rate measuring devices 100a, 100b, 100c, and 100d are used to prevent crosstalk between radio waves transmitted from the respective measuring devices. Respectively use different communication bands, and the position and time information receiving unit 200 includes position and time information transmitting units 130a, 130b, 130c, and 130d of the plurality of flow velocity and flow rate measuring devices 100a, 100b, 100c, and 100d. It is desirable to form a multi-channel structure to receive radio waves of each communication band.
이러한 구성을 취하는 경우, 다채널의 위치 및 시간정보 수신부(200)는 각각의 채널마다 각각의 측정장치(100a, 100b, 100c, 100d)로부터의 정보를 수신할 수 있으므로, 하천의 각 경로의 유속 및 유량을 측정하여, 하천의 전체적 거동을 더욱 정확히 파악할 수 있다.In this configuration, since the multi-channel position and time information receiving unit 200 can receive information from each measuring apparatus 100a, 100b, 100c, 100d for each channel, the flow velocity of each path of the stream. And by measuring the flow rate, it is possible to more accurately understand the overall behavior of the stream.
이상은 본 발명에 의해 구현될 수 있는 바람직한 실시예의 일부에 관하여 설명한 것에 불과하므로, 주지된 바와 같이 본 발명의 범위는 위의 실시예에 한정되어 해석되어서는 안 될 것이며, 위에서 설명된 본 발명의 기술적 사상과 그 근본을 함께 하는 기술적 사상은 모두 본 발명의 범위에 포함된다고 할 것이다.Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
