Description
본 발명은 전력량계의 원격검침장치에 관한 것으로, 더욱 상세하게는 가정에서 또는 산업시설에서 사용전력량을 측정하기 위하여 설치된 아날로그전력량계에서 사용전력량을 검출하여 중앙제어부에 그 데이터를 읽어낼 수 있도록 구성된 전력량계의 원격검침장치에 관한 것이다.The present invention relates to a remote meter reading device of a wattmeter, and more particularly, to a power meter configured to detect the amount of power used in an analog wattmeter installed to measure the amount of power used at home or in an industrial facility and to read the data in the central control unit. It relates to a remote meter reading device.
일반적으로, 전기를 사용하는 수요가인 가정이나 산업시설에는 사용한 전기량을 측정하기 위해 아날로그방식의 전력량계가 설치되어 있고, 이 아날로그방식의 전력량계는 회전되는 원판의 회전량에 따라 소비전력이 숫자로 표시되는 방식이다.In general, in homes or industrial facilities where demand for electricity is used, an analog electricity meter is installed to measure the amount of electricity used, and the analog electricity meter is displayed numerically according to the amount of rotation of the rotating disk. That's how it works.
이때, 상기한 전력량계는 월별로 검침원이 각 수요가를 방문하여 소비전력량을 검침한 후, 전력회사에서 검침된 전력소비량을 바탕으로 요금을 청구하게 된다.At this time, the electricity meter reads the electricity consumption by the meter reader visited each month, and then charges a fee based on the electricity consumption metered by the utility company.
그러나, 이러한 종래의 소비전력량 검침방식은 많은 검침원이 소요되어 과다한 비용이 발생되고, 이러한 비용발생은 전기요금에 그대로 반영되어 수요가에게 부담을 주게 된다.However, such a conventional power consumption meter reading method requires a large number of meter readers, and excessive costs are generated, and such a cost is reflected in the electricity bill, which burdens the demand price.
또한, 수요가의 전력소비량이 전적으로 검침원의 검침결과에 의존하기 때문에 정확한 전기요금산정에 많은 부작용이 발생되고 있다.In addition, since the power consumption of the demand price depends entirely on the meter reading result of the meter reader, many side effects occur in accurate electric bill calculation.
본 발명은 가정에서 또는 산업시설에서 사용전력량을 측정하기 위하여 설치된 아날로그전력량계에서 검출센서를 이용하여 사용전력량을 검출한 후, 연산부에 적산 및 저장하고, 중앙제어부에서 연산부의 데이터를 읽어낼 수 있도록 구성됨으로써 정확한 요금산정 및 비용절감을 유도할 수 있는 전력량계의 원격검침장치를 제공함에 그 목적이 있다.The present invention is configured to detect the amount of power using the detection sensor in the analog wattmeter installed to measure the amount of power used in the home or industrial facilities, and then integrated and stored in the calculation unit, the central controller to read the data of the calculation unit The purpose of the present invention is to provide a remote meter reading device of the electricity meter that can induce accurate billing and cost reduction.

도면을 참조하여 본 발명을 상세히 설명하기로 한다.The present invention will be described in detail with reference to the drawings.
도1은 본 발명에 따른 전력량계의 원격검침장치중 검출센서의 설치상태를 나타내는 구성도이고, 도2는 본 발명에 따른 전력량계의 원격검침장치를 나타내는 블록도이며, 도3 내지 도5는 본 발명에 따른 전력량계의 원격검침장치를 나타내는 회로도이다.1 is a block diagram showing an installation state of a detection sensor of the meter reading remote meter according to the present invention, Figure 2 is a block diagram showing a remote meter reading device of the electricity meter according to the present invention, Figures 3 to 5 Is a circuit diagram showing a remote meter reading device of the electricity meter.
본 발명은 사용된 전력량을 원격검침할 수 있도록 기존 아날로그방식의 전력량계(1)로부터 사용전력량을 검침하여 신호로 변환 및 증폭하는 검출부(10)와 증폭부(20)로 구성되어 있다.The present invention is composed of a detector 10 and an amplifier 20 for converting and amplifying a power consumption from a conventional analog electricity meter (1) to convert and amplify a signal to remotely measure the amount of power used.
여기서, 본 발명의 검출부(10)에서는 검출센서(11)가 기존 아날로그방식의전력량계(1)에서 회전원판(2)상에 표시된 검은 색의 검출띠(3)를 감지할 수 있도록 구성되어 있다.Here, in the detection unit 10 of the present invention, the detection sensor 11 is configured to detect the black detection band 3 displayed on the rotating disc 2 in the conventional analog electricity meter 1.
다시 말하면, 검출부(10)의 검출센서(11)는 회전원판(2)의 일측에 표시된 검출띠(3)와 2∼3㎜정도로 이격되도록 고정 설치되어 있고, 검출띠를 한 번 검출할 때마다 펄스를 발생시키게 되며, 검출센서(11)에서 검출띠(3)를 검출할 때마다 회전원판(2)은 1회 회전을 하게 된다.In other words, the detection sensor 11 of the detection unit 10 is fixedly spaced apart from the detection band 3 displayed on one side of the rotating disc 2 by about 2 to 3 mm, and each time the detection band is detected once. A pulse is generated, and the rotation disc 2 rotates once every time the detection sensor 11 detects the detection band 3.
그리고, 검출센서(11)에서 검출띠(3)를 검출할 때마다 발생되는 검출부(10)의 펄스신호는 증폭부(20)에서 증폭되고, 연산부(30)에서 읽어들이기에 충분한 신호로 증폭 변환된 신호는 연산부(30)로 전송이 이루어지게 된다.Then, the pulse signal of the detection unit 10 generated each time the detection sensor 11 detects the detection band 3 is amplified by the amplifier 20 and converted into a signal sufficient to be read by the calculation unit 30. The signal is transmitted to the operation unit 30.
이때, 연산부(30)로 전송된 증폭신호는 먼저 제1연산처리기(31)에 약 30KHz의 주파수로 입력되고, 이러한 영역의 신호주파수는 낮과 밤, 또는 빛의 밝기 등과 관계없이 검출센서(11)의 검출신호를 제1연산처리기에 정확히 전송하게 된다.At this time, the amplified signal transmitted to the operation unit 30 is first input to the first operation processor 31 at a frequency of about 30KHz, and the signal frequency of this area is detected by the detection sensor 11 regardless of day or night or brightness of light. ) Is accurately transmitted to the first processor.
또한, 연산부(30)의 제1연산처리기(31)에서는 수신된 검출신호를 데이터화한 다음, 다시 그 데이터를 증가된 값으로 제2연산처리기(32)로 전송하게 되고, 연산부(30)의 제2연산처리기(32)에서는 증가된 데이터값을 적산 등의 연산처리 후, 저장하게 된다.In addition, the first operation processor 31 of the operation unit 30 converts the received detection signal into data, and then transmits the data to the second operation processor 32 with the increased value again. The binary computing processor 32 stores the increased data value after arithmetic processing such as integration.
이처럼, 연산부(30)에서 제1연산처리기(31)가 증폭부(20)로부터 수신된 증폭신호를 데이터화하는 동안, 제2연산처리기(32)가 제1연산처리기로부터 수신된 데이터의 증가값을 연산처리한 후 전송하도록 함으로써, 복잡한 장소와 시간에 관계없이 정확한 데이터를 전송할 수 있게 된다.In this way, while the first operation processor 31 data-processes the amplified signal received from the amplification unit 20 in the operation unit 30, the second operation processor 32 receives an increase value of the data received from the first operation processor. By transmitting after processing, accurate data can be transmitted regardless of a complicated place and time.
그리고, 연산부(30)의 제2연산처리기(31)에서 출력되는 데이터는 데이터전송부(40)를 통해 중앙제어부(50)로 직렬 전송된다.The data output from the second operation processor 31 of the operation unit 30 is serially transmitted to the central control unit 50 through the data transmission unit 40.
여기서, 데이터전송부(40)는 연산부(30)의 제2연산처리기(31)에서 출력되는 데이터를 모뎀IC(TXD, RXD 단자)를 이용하여 각 수요가의 전화선을 통해 중앙제어부(50)로 직렬 전송하게 된다.Here, the data transmission unit 40 transmits the data output from the second operation processor 31 of the operation unit 30 to the central control unit 50 through the telephone line of each demand using modem ICs (TXD, RXD terminals). Serial transmission.
이때, 데이터전송부(40)를 통해 전송되는 데이터의 전송속도는 불과 2초이내로 소요된다.At this time, the transmission speed of the data transmitted through the data transmission unit 40 takes less than 2 seconds.
그리고, 본 발명에서는 전화통화중이거나 통신선로의 장애로 인하여 데이터의 송수신에 에러가 발생되어도 자동복귀기능을 탑재하고 있어 일정시간(1분정도)이 경과되면 자동적으로 정상상태로 복귀되도록 구성되어 있다.In addition, the present invention is equipped with an automatic return function even when an error occurs in the transmission or reception of data due to a telephone call or a failure in a communication line, and is configured to automatically return to a normal state after a predetermined time (about 1 minute) elapses. .
한편, 중앙제어부(50)에서는 각 수요가별로 연산부(30)의 제2연산처리기(31)에 저장되어 있는 적산데이터를 데이터전송부(40)를 통해 1개월 또는 1일 단위로 읽어내어 디스플레이하게 된다.In the meantime, the central controller 50 reads the accumulated data stored in the second operation processor 31 of the operation unit 30 on a monthly or daily basis through the data transmission unit 40 for each demand. do.
본 발명은 가정에서 또는 산업시설에서 사용전력량을 측정하기 위하여 설치된 아날로그전력량계에서 검출센서를 이용하여 사용전력량을 검출한 후, 연산부에 적산 및 저장하고, 중앙제어부에서 그 데이터를 읽어낼 수 있도록 구성됨으로써 정확한 요금산정 및 비용절감을 유도할 수 있는 효과를 제공하게 된다.The present invention is configured to detect the amount of power using the detection sensor in the analog wattmeter installed to measure the amount of power used at home or in industrial facilities, and then integrated and stored in the calculation unit, the central control unit can read the data It provides the effect of inducing accurate billing and cost reduction.
