Description

통신거리확장장치를 갖는 무선자동수위조절기{Radio Frequency Auto Water Level Control For Long Range}Radio Frequency Auto Water Level Control For Long Range with Communication Distance Expansion Device

본 발명은 통신거리확장장치를 갖는 무선자동수위조절기로서 광역상수도가 들어가지 않은 간이 상수도의 물탱크와 관정간에 수위를 자동으로 조절하는 장치이다.The present invention is a device for automatically adjusting the water level between a water tank and a well of a simple tap water that does not contain a wide-area water supply as a wireless automatic water level controller having a communication distance extension device.

도시지역에는 광역상수도가 보급되어 있어서 물을 자유롭게 사용하고 있으나 광역상수도가 보급되지 않은 시골지역에는 각 가정이 지하수를 파서 물을 사용하고있는데 지하수의 오염 및 고갈로 인하여 지하수를 점점 더 깊게 파야하는 현실이나 고가의 비용 부담으로 개인이 단독으로 지하수를 이용하기 힘든 실정이므로 마을단위로 간이상수도 시설을 하고있다.In urban areas, wide area water supply is used, so water is freely used, but in rural areas where wide area water supply is not supplied, households use underground water to dig deeper and deeper due to pollution and exhaustion of ground water. Due to the high cost and high cost, it is difficult for an individual to use groundwater alone.

종래의 간이 상수도의 수위 조절은 사람이 직접 작동하는 수동방식을 사용하거나 자동방식도 물탱크와 관정사이에 선을 매립하여 자동으로 수위를 조절하여 왔으나 매설된 선의 부식등으로 고장이 발생하였을때에는 매립으로 인하여 어느 곳에 문제가 생겼는지 매립된 땅을 전부 파헤치기 전에는 알수 없는 실정이므로 몇가지 다른 자동수위 조절방법이 개발되어졌고 그 중 한가지로서, 설치가 간단한 무선수 위자동조절기를 일반적으로 사용하게 되었다.Conventional water supply control of simple tap water has been adjusted automatically by using a manual method operated by a person or by automatically filling a line between a water tank and a well, but when a failure occurs due to corrosion of the buried line, Because of the fact that it is not known before digging up all the land where the problem occurred, several different automatic water level control methods have been developed. As one of them, the wireless water level controller is simple to install.

그러나 무선통신은 법이 정한 한정된 출력으로 인하여 시골지역의 특성상 산악지형이 많아 한정된 출력으로 송수신이 원활치 않아 그런곳에는 중계기를 복수로 설치해야 하는 문제가 발생되고 있어 설치 시간증가의 문제, 중계기비용문제, 그로인한 고장부위의 증가의 문제가 야기되고 있는 실정이다.However, due to the limited output set by the law, the mountainous area has a lot of mountainous terrain due to the limited output of the law, so it is not easy to transmit and receive the limited output.Therefore, there is a problem in that a plurality of repeaters need to be installed. As a result, the problem of an increase in the failure area is caused.

따라서 본 발명은 상기와 같은 종래의 문제점들을 감안하여 안출한 것으로써, 본 발명의 제 1목적은 무선통신에 방해가 되는 인자를 없앰으로 한정된 출력으로 통신거리를 확장 하는것이다.Accordingly, the present invention has been made in view of the above-described conventional problems, and a first object of the present invention is to extend a communication distance to a limited output by eliminating factors that interfere with wireless communication.

그리고, 본 발명의 제 2목적은 통신거리의 확장에 따른 중계기를 별도로 설치 하지 않도록하는 것이다.In addition, the second object of the present invention is to not separately install a repeater according to the extension of the communication distance.

또한, 본발명의 제 3목적은 AC전원선이 회로에 직접 연결되지 않아 전원선을 타고 들어오는 낙뢰, 과전압, 과전류로 인한 회로를 보호하는 것이다.In addition, a third object of the present invention is to protect the circuit due to lightning, overvoltage, overcurrent coming from the power line is not connected directly to the circuit.

그리고 통신거리확장장치를 수신부와 일체화 시켜 설치를 간단화시키고도 통신거리를 확장하는 기능을 가진 것을 특징으로한다.And it is characterized by having a function to extend the communication distance even by simplifying the installation by integrating the communication distance extension device with the receiver.

본 발명의 그 밖의 목적, 특정한 장점들 및 신규한 특징들은 첨부된 도면들과 연관되어지는 이하의 상세한 설명과 바람직한 실시예들로부터 더욱 분명해질 것이다. Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

이하에서 도면을 참조하여 본 발명을 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 무선수신부의 내부구성도이다.1 is an internal configuration diagram of a wireless receiver according to the present invention.

도 2는 무선수신부의 블록도이다.2 is a block diagram of a wireless receiver.

도 3은 무선자동수위조절기의 실제 설치 예이다.3 is an actual installation example of a wireless automatic water level regulator.

물탱크측에 설치된 무선송신기(100)에서 수위데이터, 충전지 잔량데이터, 솔라전압데이터등 필요한 데이터를 무선수신기(200)에 송신하게된다.The wireless transmitter 100 installed at the water tank side transmits necessary data such as water level data, rechargeable battery remaining data, and solar voltage data to the wireless receiver 200.

이 무선송신기(100)에서 보내는 데이터는 일정한 주기로 송신하게된다. 그러면 무선수신기(200)는 수신대기 상태로 있다가 무선송신기로부터 데이터가 감지되면 수신을 시작하게된다. 이때 일반적인 수신기는 전원을 상용전원(AC아답터)을 사용하여 항상 수신대기상태로 있게된다.Data transmitted from the radio transmitter 100 is transmitted at regular intervals. Then, the radio receiver 200 is in a reception standby state and starts reception when data is detected from the radio transmitter. In this case, the general receiver always uses the commercial power supply (AC adapter) to receive standby.

그러나 본 발명의 통신거리확장 장치를 갖는 수신기는 송신기의 송신 간격에 맞추어 AC전원을 단속하게 되므로 송신기에서 송신시점 바로전에 AC전원을 물리적으로 끊어 버리고 장치된 충전지 전원(DC)으로 수신대기 상태로 있다가 송신측으로 부터 데이터를 수신받으면 정해진 명령을 수행하고 충전지 전원을 끊어버림으로 AC전원이 접속되어 충전지를 충전하게된다.However, since the receiver having the communication distance extension device of the present invention intercepts AC power according to the transmission interval of the transmitter, the AC power is physically disconnected just before the transmission time, and is in a standby state with the installed rechargeable battery power (DC). Receives data from the sender, executes the specified command and turns off the rechargeable battery power to charge the rechargeable battery.

보다 상세한 실시예로 설명하기 위해 도2를 기준으로 설명하면, 무선수신부(300)에서 송신기(100)로부터 데이터를 받게 되는데 예로 송신기의 데이터 송신주기를 3분마다 1회 송신 주기로 하여 설명하도록 하겠다.2, the wireless receiver 300 receives data from the transmitter 100. For example, the data transmission cycle of the transmitter will be described as one transmission cycle every three minutes.

수신기(200)의 전원을 ON시키면 데이터컨트롤부(400)의 MCU에 설정된 프로그램에 의해 전원인입부(1000)에 접속된 AC아답터 전원을 AC전원차단부(600)가 AC전원은 물리적으로 차단하고 충전지(800)를 접속시키고 수신대기 상태로 들어가게된다.When the power of the receiver 200 is turned on, the AC power cut-off unit 600 physically cuts off the AC adapter power connected to the power input unit 1000 by a program set in the MCU of the data control unit 400. The rechargeable battery 800 is connected and enters a reception standby state.

대기중에 송신기(100)로부터 데이터를 수신받으면 데이터컨트롤부(400)에 의하여 명령을 수행하고 나면 AC전원차단부(600)가 전원차단을 해제하여 AC전원을 연결시키게 되고 이에 따라 AC전원은 충전회로부(500)에 전류를 인가하여 충전지(800)를 충전하게된다.When receiving data from the transmitter 100 in the air, after performing a command by the data control unit 400, the AC power cut-off unit 600 releases the power cut off and connects the AC power. The rechargeable battery 800 is charged by applying a current to the 500.

충전지를 충전중에 있다가 약2분50초가 경과되면 송신부로부터 수신대기를 위해 데이터컨트롤부(400)는 명령을 내려 AC전원차단부(600)의 릴레이를 동작시켜 AC전원은 차단하고 DC전원인 충전지(800)를 접속시키게 된다.After about 2 minutes and 50 seconds while charging the rechargeable battery, the data controller 400 issues a command for standby reception from the transmitter to operate the relay of the AC power cut-off unit 600 to cut off the AC power and charge the DC battery. 800 will be connected.

이런 일련의 동작은 3분주기로 반복되어져 송신대기 상태에서는 AC전원을 물리적으로 차단하여 AC전원에서 올라오는 노이즈를 완전 차단하므로 수신효율이 증대되어 통신거리을 확장하게하는 결과를 얻게되는것이다.This series of operations is repeated in three-minute periods. In the standby mode, the AC power is physically cut off to completely block the noise coming from the AC power, which increases the reception efficiency and extends the communication distance.

이상에서 설명한 바와 같이 본 발명에 따른 통신거리확장 장치를 갖는 무선자동수위조절기(200)에 의하면 산이 많은 시골환경에 설치되어지는 무선자동송수신기의 성능을 향상시켜 통신거리문제로 추가로 설치하는 중계기의 설치 빈도을 줄임으로 설치비용을 절감시킬뿐만 아니라 원활한 통신으로 마을주민의 식수 사용에 불편함이 없도록 기여하게 될것이다.As described above, the wireless automatic water level controller 200 having the communication distance extension device according to the present invention improves the performance of the wireless automatic transmitter and receiver installed in a mountainous rural environment, thereby improving the performance of the repeater installed as a communication distance problem. It will not only reduce the installation cost by reducing the frequency of installation but also contribute to the inconvenience of drinking water for village residents through smooth communication.

특히 중계기는 사용전류가 많아 솔라충전패널의 크기도 커지고 충전지 용량도 큰 것으로 해야하는 관계로 설치 위치 선정에도 어려움이 있었으나 이것을 해결하는게 큰 역할을 할것이다.In particular, the repeater has a large amount of current, so the size of the solar charging panel should be large and the capacity of the rechargeable battery should be large. Therefore, it was difficult to select the installation location.

비록 본 발명이 상기에서 언급한 바람직한 실시예와 관련하여 설명되어졌지만 본 발명의 요지와 범위로부터 벗어남이 없이 다른 다양한 수정 및 변형이 가능할 것이다. 따라서, 첨부된 청구의 범위는 본 발명의 진정한 범위내에 속하는 그러한 수정 및 변형을 포함할 것이라고 여겨진다.Although the invention has been described in connection with the preferred embodiments mentioned above, other various modifications and variations may be made without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.

시골지역등 광역상수도가 보급되지 않은지역에 마을 간이상수도가 운용되고 있다.The inter-urban water supply system is operated in areas where the wide-area water supply is not spread, such as rural areas.

이 간이상수도는 지하수관정을 파고 수중모터를 장착하여 산중턱등 마을의 높은지역에 물탱크를 설치하여 관정에서 수중모터를 가동시켜 물탱크로 물을 끌어올린다음 자연압에 의하여 개별 가정으로 물을 공급하는 것이다.The Gansang Water Supply digs underground water wells, installs an underwater motor, installs a water tank in high areas of the village such as mountainsides, runs an underwater motor from the well, and pulls water into the water tank. To supply.

무선자동수위조절기는 이 시스템을 자동으로 운용시키는 것으로 물탱크의 물이 저수위일때는 관정모터를 기동시키고, 물탱크의 수위가 고수위가 되면 모터를 중지 시키는 역할을 하는것이다.The wireless automatic water level regulator operates this system automatically. When the water level in the water tank is low, it starts the well motor and stops the motor when the water tank becomes high.
