Abstract

본 발명은 적산전력계 검침 회로에 관한 것으로 특히 무선통신을 이용하는 회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a meter reading meter for a cumulative power meter, and more particularly to a circuit using wireless communication.

종래에는 사람이 가가호호 방문하여 검침을 하므로서 많은시간과 인력이 필요하였다.In the past, many people needed a lot of time and manpower because people visited Gaga and visited the meter.

따라서 본 발명은 무선통신을 이용함으로서 인력 및 시간을 절약하도록 하는 것을 목적으로 하고 있다.Accordingly, the present invention aims to save manpower and time by using wireless communication.

본 발명의 적산전력계 자동검침회로는 상기와 같은 목적을 달성하기 위해서 다음과 같은 구성으로 이루어졌는바 도면을 참고로하여 이를 상세하게 설명하겠다.The automatic meter reading circuit for a meter of the present invention has the following structure in order to achieve the above object, and will be described in detail with reference to the drawings.

우선 제1도는 본 발명의 전체 시스템 구조를 나타내는 블록도로서 도면에 나타낸 바와 같이 본 발명은 전원입력부(101), 전원출력부(102), 트랜스(103), 전류감지코일(104), 분배저항(105), 브리지다이오드(106), 충전용밧데리(107), 전자회로블록도(108)로 이루어져 있다.1 is a block diagram showing an entire system structure of the present invention. As shown in the drawing, the present invention includes a power input unit 101, a power output unit 102, a transformer 103, a current sensing coil 104, A charging diode 105, a bridge diode 106, a charging battery 107, and an electronic circuit block 108.

동작상태를 상세히 설명하면 전원입력부(101)에서 전원이 입력되면 트랜스(103),다이오드(106)를 경유하여 충전용 밧데리(107)에 전원이 충전되고 충전된 전원은 전자회로(108)에 전원을 공급한다.When the power is inputted from the power input unit 101, the power for charging the battery 107 is charged via the transformer 103 and the diode 106 and the charged power is supplied to the electronic circuit 108 from the power source .

사용자가 전기를 사용하게되면 전류감지코일(104)에서 전류가 감지되고 감지된 전류는 저항(105)에 의하여 전압으로 바뀌고 이 측정된 전압은 AD변환부(111)에 입력되어 디지탈값으로 변환되어 CPU(109)에 입력된다. CPU(109)에서는 입력된 디지털값은 전력량으로 환산하여 LCD 화면에 계속적으로 표시하며 무선수신부(112)에서 수신코멘트가 입력되면 CPU(110)에서 신호를 판독한 후 전력량 및 상태값을 무선송신부(113)를 통하여 송신하게 하는 회로 및 구성.When the user uses electricity, current is sensed in the current sensing coil 104 and the sensed current is converted into a voltage by the resistor 105. The measured voltage is input to the A / D converter 111 and converted into a digital value And is input to the CPU 109. [ In the CPU 109, the input digital value is converted into the amount of electric power and continuously displayed on the LCD screen. When the reception comment is inputted in the wireless reception unit 112, the CPU 110 reads the signal and then transmits the power amount and the state value to the wireless transmission unit 113).

Claims

The integrated power meter receives the power input 101 to supply power to the control circuit through the transformer 103, the diode 106 and the rechargeable battery. When the user uses the power source, the current is detected by the current sensing coil 104 And converted into a digital value by the A / D conversion unit 105 via the resistor 105. The converted value is transferred to the CPU 109, converted into the amount of power and displayed on the LCD screen, And to transmit a power amount or status register value to the wireless transmission unit (114).
