Description
본 고안은 수조 및 기타 액체 저장탱크에 저장된 액체의 수위를 조절할 수 있도록 하는 수위조절장치에 관한 것으로, 더 자세하게는 수위감지기와 제어기에 무선통신수단을 마련하여 수조로부터 멀리 떨어진 곳에 설치된 제어기를 통해 수위를 원격 제어할 수 있도록 하는 무선통신을 이용한 원격 수위조절장치에 관한 것이다.The present invention relates to a water level control device for adjusting the level of liquid stored in a tank and other liquid storage tank, and more particularly, by providing a wireless communication means in the level sensor and controller, the water level through a controller installed far from the tank It relates to a remote water level control device using a wireless communication to enable remote control.
최근 들어 무선통신기술의 눈부신 발달으로 인하여 원거리에서도 무선으로 각종 기계설비를 작동시킬 수 있도록 하는 원격제어장치가 널리 사용되고 있다.Recently, due to the remarkable development of wireless communication technology, a remote control device that can operate various mechanical equipments wirelessly from a long distance has been widely used.
즉, 교량의 침하상태를 체크하여 무선으로 송신함으로써 교량의 붕괴를 방지할 수 있도록 하는 교량안전제어장치 등의 출현으로 원거리에서 간편하게 각종 구조물이나 기계설비를 점검, 제어할 수 있게 되어 제어장치의 설치 및 구조물 등의 관리를 보다 경제적으로, 또 안전하게 할 수 있게 되었다.In other words, with the emergence of the bridge safety control device that prevents the bridge from collapsing by checking the settlement state of the bridge and transmitting it wirelessly, it is possible to easily check and control various structures and mechanical equipment from a long distance. And management of structures and the like can be made more economically and safely.
그러나 종래에는 대형건물의 옥상에 설치되는 물탱크나 지하에 설치되는 하수 처리시설의 수조, 또는 주유소의 기름탱크, 화학공장이나 핵처리시설의 액체원료가 저장되는 저장탱크 등 각종 액체가 저장되는 수조의 수위를 감지, 제어할 수 있도록 하는 수위조절장치에 있어서 이와 같은 무선통신을 이용한 제어방식이 접목되지 못한 실정이었기 때문에 수위감지기와 제어기를 유선으로 연결하여 수위감지기의 신호를 제어기에 송출할 수밖에 없었다.However, conventionally, a tank for storing various liquids such as a water tank installed on a roof of a large building, a tank of a sewage treatment facility installed underground, an oil tank of a gas station, a storage tank storing liquid raw materials of a chemical plant or a nuclear processing facility, etc. In the water level control device that can detect and control the water level, the control method using wireless communication was not applied. Therefore, the water level sensor signal was transmitted to the controller by connecting the water level sensor and the controller by wire. .
상기 종래의 유선방식은 선로의 상태가 양호하다면 다른 간섭신호를 받을 우려가 없기 때문에 수위감지기의 신호가 제어기에 비교적 확실하게 전달되는 잇점은 있으나 수위감지기와 그로부터 멀리 떨어진 제어기 사이에 선로공사를 하여야 하므로 시설비용이 많이 들게 되고, 그로 인해 제어기를 수위감지기와 되도록 가깝게 설치하여야 하기 때문에 제어기의 위치 선정에도 많은 제약이 따르게 되는 문제가 있었다.The conventional wired method has the advantage that the signal of the water level detector is transmitted to the controller relatively reliably because there is no fear of receiving another interference signal if the state of the line is good, but it is necessary to perform the line construction between the water level sensor and the controller farther from it. There is a problem in that the cost of the facility is high, and therefore, the controller must be installed as close as possible to the water level sensor, so that many restrictions are placed on the location of the controller.
또한 종래의 유선방식은 장기간 사용으로 선로상태가 나빠지게 되면 오동작의 우려가 많게 되므로 보수를 하여야 하지만 선로의 철거 및 재시공의 공사가 어려워 보수비용이 많이 들게 되는 등 그 사후관리에 있어서도 많은 문제점이 있었다.In addition, the conventional wired system has a lot of problems in the post-management, such as the long-term use of the line condition is bad, there is a risk of malfunction, so the repair should be performed, but the cost of the repair and repair of the track is difficult due to the difficult construction of the track and reconstruction. .
본 고안은 상기 종래의 유선방식의 제결함을 감안하여 안출한 것이며, 그 목적은 수위감지기의 감지신호를 제어기에 무선으로 송출할 수 있도록 하는 것에 의해 설비비용 및 관리비용을 절감할 수 있도록 하는 무선통신을 이용한 원격 수위감지장치를 제공하는 데에 있는 것이다.The present invention has been made in view of the deficiencies of the conventional wired method, the purpose of which is to wirelessly transmit the detection signal of the water level sensor to the controller to reduce the equipment cost and management cost wireless It is to provide a remote water level sensing device using communication.

도면부호중 미설명부호 35는 표시기, 36은 출력기이다.Reference numeral 35 in the drawings denotes an indicator and 36 an output device.
이와 같이 구성된 본 고안에 있어서는 도 2와 같이 수위감지기(2)에서 감지된 감지신호가 신호변환기(11)를 통해 변환된 후 신호제어기(12)를 거쳐 송신기(13)로 송출되며, 제어기(3)의 수신기(34)를 통해 수신된 전파는 도 4와 같이 신호제어기(32) 및 신호변환기(31)를 거쳐 표시기(35) 및 출력기(36)로 보내진다.In the present invention configured as described above, as shown in FIG. 2, the detection signal detected by the water level sensor 2 is converted through the signal converter 11, and then sent to the transmitter 13 through the signal controller 12 and the controller 3.

그리고 표시기(35)는 수신된 신호에 의거하여 디지털이나 지침 등의 표시수단으로 현재의 수위를 표시하고, 출력기(36)는 각종 펌프나 밸브에 제어신호를 출력하게 된다.The indicator 35 displays the current water level by display means such as digital or instructions based on the received signal, and the output unit 36 outputs a control signal to various pumps or valves.
한편 본 고안에 있어서는 수위감지기(2)와 제어기(3)의 사이에 거리가 너무 멀어서 감지신호가 약하게 전달될 때는 그들 사이에 설치되는 적어도 하나이상의 중계기(20)를 통해 감지신호를 중계할 수 있게 되는 바, 도 3과 같이 중계기(20)는 신호제어기(22)의 양방향에 각각 설치된 송신기(23a)(23b)와 수신기(24a)(24b)를 통해 수위감지기(2)의 무선통신기(10) 및 제어기(3)의 무선통신기(30)와 교신하게 된다.Meanwhile, in the present invention, when the detection signal is weakly transmitted because the distance between the water level sensor 2 and the controller 3 is too long, the detection signal may be relayed through at least one or more repeaters 20 installed therebetween. As shown in FIG. 3, the repeater 20 is a wireless communication device 10 of the water level sensor 2 through the transmitters 23a and 23b and the receivers 24a and 24b respectively installed in both directions of the signal controller 22.

As a result, according to the present invention, since there is no need to connect the water level detector 2 and the controller 3 by wire, it is possible not only to reduce the enormous construction cost associated with the conventional line construction but also to Since the controller 3 can be installed regardless of the installation position, the water level management can be efficiently performed even at a position far from the water tank 1.
또한 본 고안에 의하면 선로의 노후로 인한 오동작의 우려가 없게 됨은 물론 잦은 선로교체로 인한 유지보수비용을 절감할 수 있게 되는 등의 효과를 얻을 수 있다.In addition, according to the present invention, there is no fear of malfunction due to the aging of the track, and it is possible to reduce the maintenance cost due to frequent replacement of the track.
