본 발명은 하천에 부자(浮子)를 투하하여 유량을 측정하는 부자식 유량측정에 관한 것으로, 부자에 상용 이동통신 신호를 송출하는 발신부를 설치하여 이동통신망을 통하여 이 신호를 수신함으로써 그 위치를 추적할 수 있도록 한 것이다.The present invention relates to a subsidiary type flow measurement for measuring the flow rate by dropping the rich in the river, the location is installed by the transmitter to send a commercial mobile communication signal to the rich to receive the signal through the mobile communication network to track its location It is to be done.

하천의 유량측정은 하천의 수위-유량관계를 도출하기 위한 기본적 수문(水文)조사로서, 하천에 소정의 측정지점을 선정한 후, 해당 지점의 수위와 유량의 동시관측을 다회 실시함으로써 수위-유량관계의 도출을 위한 회귀분석의 기본자료를 수집하는 것이다.The flow measurement of the stream is a basic hydrological survey to derive the water level-flow relationship of the stream. After selecting a predetermined measurement point in the stream, the water level and the flow rate are measured by performing the simultaneous observation of the water level and the flow rate at that point. It is to collect the basic data of regression analysis for derivation.

하천의 유량측정은 홍수, 평수 및 갈수 등 하천의 유황별로 다수의 측정자료가 획득되어야 유의한 하천-유량관계를 도출할 수 있는 바, 주요 하천의 경우 매년 수회 이상의 측정작업이 이루어지며, 특히 홍수시 유량의 경우 수해방지 대책의 수 립, 홍수예경보 및 홍수량산출 등에 핵심 자료로 사용되므로 그 중요성이 매우 크다.In order to measure the flow rate of rivers, a large number of measurement data must be obtained for each stream sulfur such as flood, plain water and dry water to derive significant stream-flow relations. City flow is very important because it is used as key data in establishing flood prevention measures, flood forecasting and flood calculation.

일반적으로 홍수시의 유량측정에 있어서는 일반 유속계를 통한 측정이 매우 위험할 뿐 아니라 그 정확성이 낮으므로, 하천을 횡단하는 교량 등의 구조물에서 부자를 투하한 후 그 유하속도를 측정하고 유하구간의 하천단면적을 고려하여 유량을 산출하는 부자식 유량측정법이 적용된다.In general, the flow rate measurement during flooding is not only very dangerous but also low in accuracy. Therefore, after the rich is dropped from structures such as bridges crossing rivers, the flow rate is measured, A parent flow measurement method is applied to calculate the flow rate taking into account the cross-sectional area.

그러나 이러한 종래의 부자식 하천 유량측정방법은 기본적으로 유하구간에 대한 목측(目測)을 통하여 부자의 유하속도를 측정하게 되는 바, 그 정확성이 낮을 뿐 아니라 투하를 담당하는 사람 외에 투하 후 측정구간에서 부자의 측정구간 진입시부터 이탈시에 이르는 유하상황을 관찰하고 유하시간을 측정하는 관측원이 필요하며, 경우에 따라 측선(測線)별로 다수의 부자가 연속하여 투하되기도 하므로 다수의 관측원이 소요되는 등, 유량측정에 많은 인원이 소요되는 문제점이 있었다.However, this conventional method of measuring the flow of the rich river is basically measured the flow rate of the rich through the neck side (目測) for the flow section, the accuracy is not only low, but in addition to the person in charge of the drop in the measurement section after the discharge Observers are required to observe the flow situation from entering and exiting the measurement section of the rich, and to measure the drifting time.In some cases, a large number of rich people are continuously dropped per sideline. There is a problem in that a large number of personnel are required for flow measurement.

또한, 부자의 유하속도 측정은 초시계 등을 통한 설정구간 통과시간의 측정을 통하여 이루어지는 방식으로서, 일단 투하된 부자는 특정 구간내에서만 사용될 수 있으므로 동일한 하천의 동일한 사상(事象)의 홍수에 있어서도 측정구간이 다를 경우 전체 인원이 해당 측정구간으로 이동한 후 새로운 부자를 투하하고 측정구간 통과시간을 측정해야 했으며, 따라서 유량측정에 많은 인원 및 시간이 소요되고 측정구간의 설정에도 한계가 있을 수 밖에 없었다.In addition, the measurement of the flow rate of the rich man is made through the measurement of the passage time of the set section through a stopwatch, etc., because the rich man once dropped can only be used within a certain section, even in the flood of the same event of the same river. In other cases, the whole personnel moved to the relevant measurement section, and the new rich man had to drop and measure the passage time of the measurement section. Therefore, it took a lot of people and time to measure the flow rate, and there was a limitation in setting the measurement section.

이에 공개특허 제2004-17074호에서와 같이, 하천 유량측정시 관측데이터를 기록하는 야장(野帳)을 PDA등의 휴대형 전자기기에 구현하고, 측정데이터를 이동통 신망이나 무선랜 등을 통하여 송신하는 기술이 개발된 바 있으나, 이는 어디까지나 유량측정이 이루어진 후 데이터의 기록 및 처리과정상 편의에 관한 것을 뿐, 실제 하천의 유량측정은 모두 목측(目測)으로 이루어져야 하는 문제점이 있었다.Accordingly, as disclosed in Korean Patent Laid-Open No. 2004-17074, a field field for recording observation data during river flow measurement is implemented in a portable electronic device such as a PDA, and the measured data is transmitted through a mobile communication network or a wireless LAN. This technology has been developed, but this is only about the convenience of the recording and processing process of data after the flow measurement is made to the last, there was a problem that the flow measurement of the actual river all made of the neck side (目測).

즉, 실제 측정과정은 전통적인 방법과 동일하고 다만 측정결과의 기록 및 처리과정에 있어서만 휴대형 전자기기를 이용하는 것으로, 하천 실제 유량측정과정을 개선했다기 보다는 측정 후 야장기입 및 내업(內業)에 있어서의 편의를 확보한 것이다.In other words, the actual measurement process is the same as the traditional method, but the portable electronic device is used only in the recording and processing of the measurement results. It is to ensure convenience.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 부자식 하천 유량측정에 사용되는 부자를 구성함에 있어서, 부자 상부에 상용 이동통신 신호를 발신하는 송신장치를 설치하여 부자의 유하시 소정의 신호를 발신하도록 하고, 하천 주변의 이동통신 기지국이 이 신호를 수신하여 그 위치를 추적하도록 함으로써 부자의 유하속도를 측정할 수 있도록 한 것이다.The present invention has been made in view of the above-mentioned problems. In the construction of the rich used for the measurement of the rich river flow, there is provided a transmission device for transmitting a commercial mobile communication signal on the upper part to provide a predetermined signal when the rich is present. The mobile communication base station around the river receives this signal and tracks its location so that the floating speed of the rich can be measured.

또한, 부자에는 상기의 송신장치외에도 부자의 수평상태를 감지하는 수평센서를 설치하여 유하중 부자의 기울기정보를 송신할 수 있도록 함으로써 더욱 정확한 관측이 가능하도록 한 것이다.In addition, in addition to the above-mentioned transmission device, the rich man is equipped with a horizontal sensor for detecting the horizontal state of the rich man to be able to transmit the slope information of the load-rich rich man to enable more accurate observation.

본 발명의 상세한 구성 및 작동원리를 첨부된 도면을 통하여 설명하면 다음 과 같다.The detailed configuration and operation principle of the present invention will be described with reference to the accompanying drawings.

우선 도 1 및 도 2는 본 발명을 통한 유량측정 즉, 부자(10)의 위치추적을 통한 하천의 유속측정 원리를 설명한 것으로, 부자(10)가 하천에 투하되어 하천을 따라 유하하면서 상용 이동통신 신호를 송신함에 따라 주변의 이동통신 기지국(31)이 이 신호를 수신하여 그 위치를 추적하게 된다.1 and 2 illustrate the flow rate measurement principle of the flow rate through the present invention, that is, the flow rate measurement of the river through the location tracking of the rich man 10, while the rich man 10 is dropped in the river and flows along the river to commercially available mobile communication. As the signal is transmitted, the surrounding mobile communication base station 31 receives the signal and tracks its position.

본 발명의 부자(10)는 상용 이동통신 신호를 발생하는 일종의 이동통신단말기로서, 도 2에서와 같이 부자(10)와 인접한 3개의 기지국(31)별 수신지연시간(round trip delay)을 산출하여 부자(10)와 각 기지국(31)간의 직선거리를 산정함으로써 부자(10)의 좌표를 획득하게 되며, 이 과정을 소정의 시간간격으로 반복하여 부자(10)의 위치를 추적하게 되는 것이다.The rich 10 of the present invention is a kind of mobile communication terminal for generating a commercial mobile communication signal, and calculates a round trip delay for each of three base stations 31 adjacent to the rich 10 as shown in FIG. By calculating the linear distance between the rich man 10 and each base station 31 to obtain the coordinates of the rich man 10, this process is repeated at a predetermined time interval to track the position of the rich man 10.

이러한 이동통신망 기반의 위치파악에 있어서 거리산출을 위한 신호설정 및 채널부여 등에 있어 다양한 방식이 있을 수 있으나, 본 발명은 이동통신망내 발신체에 대한 위치검색방법 자체에 관한 것이 아니라, 이를 통한 유량측정용 부자(10)에 관한 것이므로, 기지국(31)과 발신체간 거리산출의 구체적인 방식에 대한 청구범위의 한정은 하지 않는다.In the mobile communication network-based location determination, there may be various methods in setting signals and granting channels for distance calculation. However, the present invention does not relate to the location retrieval method itself for the sender in the mobile communication network, and to measure the flow rate therethrough. As it relates to the rich and rich 10, the limitation of the claims for the specific method of calculating the distance between the base station 31 and the sender is not limited.

도 3 및 도 4는 각각 본 발명의 구체적인 구성이 도시된 분해사시도 및 본 발명의 송신장치(20) 블럭도로서, 본 발명은 기본적으로 하부가 폐쇄되어 부력을 가지는 관체(管體)(11) 형태를 가지며, 하단부에는 중량물(12)이 설치되어 무게중심을 하단부에 위치하도록 하고, 상부에는 송신장치(20)가 내장된 하우징(29)이 탈부착 가능하도록 결합된 형태를 가진다.3 and 4 are respectively an exploded perspective view showing a specific configuration of the present invention and a block diagram of the transmission device 20 of the present invention. The present invention basically includes a closed body 11 having a buoyancy due to a closed lower part. It has a form, the weight 12 is installed at the lower end so that the center of gravity is located at the lower end, the upper has a form in which the housing 29 in which the transmission device 20 is built so as to be detachable.

일반적으로 하천의 표면유속이 평균유속에 비하여 크므로, 평균유속을 획득하기 위하여 표면부자보다는 본 발명과 같은 봉부자(棒浮子) 형식의 부자(10)가 선호되고 있으며, 봉부자는 하천의 수심에 따라 관체(11)의 길이는 물론 흘수(吃水)를 조절해야할 필요성이 있으므로 관체(11)와 하우징(29)을 탈부착식으로 구성하여 다양한 길이의 관체(11)를 적용할 수 있도록 하고 중량물(12)의 중량도 조절할 수 있도록 하였다.In general, since the surface flow velocity of the river is larger than the average flow rate, in order to obtain the average flow rate, the rich man 10 like the present invention is preferred to the surface rich man, and the sealer has a depth of the river. According to the need to adjust the length of the tubular body 11 as well as the draft (吃水), so that the tubular body 11 and the housing 29 to be detachably configured to be applied to the tubular body 11 of various lengths and weight ( The weight of 12) was also adjusted.

즉, 본 발명의 하우징(29)과 관체(11)는 나사 등을 통하여 탈부착이 가능하도록 구성하고, 유량측정전에 관체(11)에 모래 등의 중량물(12)을 투입하되 그 양을 조절함으로써 부자(10)의 흘수를 조절할 수 있도록 한 것이다.That is, the housing 29 and the tube body 11 of the present invention are configured to be detachable through screws and the like, and the heavy material 12 such as sand is put into the tube body 11 before the flow rate measurement, but the amount is adjusted by adjusting the amount. This is to control the draft of (10).

하우징(29)에 내장되는 송신장치(20)는 기본적으로 도 4에서와 같은 구성을 가지는데, 도시되지는 않았지만 전지를 전원으로 하여 작동되며 안테나(21)는 송신효율을 확보하기 위하여 하우징(29) 외부로 노출되도록 구성된다.Transmitter 20 embedded in the housing 29 basically has the same configuration as in Figure 4, although not shown is operated using a battery power source and the antenna 21 is a housing 29 to secure the transmission efficiency ) Is configured to be exposed to the outside.

송신장치(20)의 발신부(23)는 해당 부자(10)를 식별할 수 있는 일련번호 형태의 식별정보를 송출하도록 구성할 수 있으며, 발진(發震)된 신호는 증폭부(22)를 통하여 증폭되어 안테나(21)로 송신된다.The transmitting unit 23 of the transmitting device 20 may be configured to transmit identification information in the form of a serial number for identifying the rich person 10, and the oscillated signal may cause the amplifying unit 22 to transmit. Amplified through and transmitted to the antenna 21.

한편, 도 5는 실제 부자(10)가 유하중인 하천의 종단면을 도시하고 있는데, 동 도면을 통하여 알 수 있는 바와 같이, 표면유속과 측정수심의 유속은 차이를 보이게 되며, 통상 표면유속이 더 크게 되므로 부자(10)는 유하방향의 전후측으로 전도와 복원을 반복하면서 유하하게된다.On the other hand, Figure 5 shows the longitudinal section of the river, the actual rich man 10, as can be seen through the figure, the flow velocity of the surface flow rate and the measurement depth will show a difference, the surface flow rate is usually larger Therefore, the rich man 10 will fall while repeating the conduction and restoration to the front and rear side of the flow direction.

즉, 수면 위로 노출된 부자(10)의 안테나(21)를 비롯한 송신부는 그 위치가 유하방향 전후로 왕복되는 운동을 반복하게 되며, 따라서 정확한 하천 평균유속을 산정하기 위해서는 무게중심인 부자(10) 하부의 위치를 추적해야 하는 바, 도 6에서와 같이 송신장치(20)에 수평센서(26)를 설치하여 부자(10)의 기울기를 측정함으로써 실제 부자(10)의 무게중심 위치를 환산할 수 있도록 한 것이다.That is, the transmission unit including the antenna 21 of the rich 10 exposed on the water surface repeats the movement of the position is reciprocated back and forth in the flow direction, and therefore, in order to calculate the accurate stream average flow rate, the lower part of the rich 10 is the center of gravity. 6, the horizontal sensor 26 is installed on the transmitter 20 to measure the inclination of the rich man 10 so that the center of gravity of the rich man 10 can be converted. It is.

이러한 부자(10)의 기울기정보 송신은 통상의 상용 이동통신망에서 별도의 부가장비없이도 사용가능하도록 제공하고 있는 단문메시지서버스(SMS, short message service)를 통하여 수행될 수 있다.Such rich information transmission of the rich 10 may be performed through a short message service (SMS) that is provided to be used without additional equipment in a conventional commercial mobile communication network.

수평센서(26)를 통하여 취득된 부자(10)의 기울기는 AD변환부(analogue to digital converter)(25)에 의하여 디지털신호로 변환된 후 발신부(23)에 연결된 단문발생부(24)에 입력되고, 단문발생부(24)에서 발생된 단문신호는 발신부(23)와 증폭부(22)를 거쳐 안테나(21)를 통하여 발신된다.The slope of the rich man 10 obtained through the horizontal sensor 26 is converted into a digital signal by an analog to digital converter 25 and then connected to the short circuit generator 24 connected to the transmitter 23. The short signal generated by the short generator 24 is transmitted through the antenna 21 through the transmitter 23 and the amplifier 22.

이동통신기지국(31)을 통하여 수신된 기울기정보는 유량측정 당사자에게 제공된 후 다양한 후처리(post-processing)과정을 거치게 되므로, 송신장치(20)가 담당하는 발신데이터는 부자(10)의 식별을 위한 일련번호 등의 식별정보와 각도데이터 정도로 단순화하는 것이 통신부하의 감소 및 송신장치(20)의 간소화에 있어서 유리하다.Since the inclination information received through the mobile communication base station 31 is provided to the flow measurement party and then undergoes various post-processing processes, the outgoing data in charge of the transmitting apparatus 20 may identify the rich 10. It is advantageous to reduce the communication load and simplify the transmission device 20 to simplify the identification information such as serial number and angle data.

이렇듯, 부자(10)의 위치를 목측(目測)으로 추적하지 않고, 이동통신망을 통하여 추적함으로써, 관측의 정확성을 확보할 뿐 아니라, 하천의 전 구간에 대한 유속측정이 가능하게 된다.As such, by tracking the position of the rich man 10 through the mobile communication network without tracking the neck side, it is possible not only to secure the accuracy of observation, but also to measure the flow velocity of the entire section of the river.

결국 본 발명의 기술요지는 부자식 하천 유량측정에 사용되는 부자(10)에 있 어서, 관체(管體)(11)로 구성된 부자(10) 하단부에는 중량물(12)이 설치되고, 부자(10) 상단부에는 송신장치(20)가 내장된 하우징(29)이 결합되되, 이 송신장치(20)는 상용 이동통신 신호를 발생하는 발신부(23)와 이를 증폭하는 증폭부(22) 및 이를 송신하는 안테나(21)를 포함함을 특징으로 하는 이동통신망을 이용한 하천 유량측정용 부자로서, 상기 송신장치(20)에는 발신부(23)와 연결되어 단문메시지를 발생하는 단문발생부(24)와, 부자(10)의 기울기를 감지하는 수평센서(26) 및 이 수평센서(26)와 단문발생부(24)를 연결하는 AD변환부(analogue to digital converter)(25)가 포함됨을 특징으로 하는 이동통신망을 이용한 하천 유량측정용 부자이다.As a result, the technical gist of the present invention is in the rich 10 used for the rich river flow measurement, the heavy material 12 is installed at the lower end of the rich 10 composed of a pipe 11, and the rich 10 The upper end portion is coupled to the housing 29 in which the transmitter 20 is built, the transmitter 20 is a transmitter 23 for generating a commercial mobile communication signal and an amplifying unit 22 to amplify it and transmit it As a rich for river flow measurement using a mobile communication network, characterized in that it comprises an antenna 21, the transmitter 20 is connected to the transmitter 23 and a short message generator 24 for generating a short message and A horizontal sensor 26 for detecting the inclination of the rich man 10 and an analog to digital converter 25 for connecting the horizontal sensor 26 and the short-circuit generator 24 to each other.
