디지털 피아노의 슬레이브 보드의 자동 인식 시스템 및 방법System and method for automatically recognizing slave board of digital piano
본 발명은 디지털 피아노에서 마스터 보드와 연결된 슬레이브 보드의 자동 인식 시스템 및 그 방법에 관한 것이다.The present invention relates to a system and method for automatically recognizing a slave board connected to a master board in a digital piano.
디지털 피아노(Digital piano)는 전통적인 피아노의 연주 방식과 소리의 대안으로 고안된 키보드의 한 종류이다. 이 피아노는 어쿠스틱 피아노(아날로그 피아노)의 정확한 시뮬레이션을 제공한다. 디지털 피아노는 업라이트 피아노 혹은 그랜드 피아노와 같이 일반적인 피아노 처럼 보이게 설계된다. 디지털 피아노의 음은 합성 에뮬레이션이나 실제 피아노 샘플을 사용하여 저장된 소리를 터치된 건반의 위치와 매칭시킨 다음 저장된 음을 스피커를 통해 송출하는 방식으로 이루어진다. 디지털 피아노의 건반은 88, 76, 61의 3종류이지만 주로 88개의 건반(키)이 이용된다.A digital piano is a type of keyboard designed as an alternative to the traditional piano playing method and sound. This piano provides an accurate simulation of an acoustic piano (analogue piano). Digital pianos are designed to look like regular pianos, such as upright pianos or grand pianos. The sound of the digital piano is made by using synthetic emulation or real piano samples to match the stored sound with the position of the touched key, and then transmits the stored sound through a speaker. Although there are three types of keyboards of digital pianos, 88, 76, and 61, 88 keys are mainly used.
디지털 피아노는, 어쿠스틱 피아노에 비해 유지 비용이 낮으며, 사운드가 미디(MIDI)로 구현되고, 학습과 작곡을 도와주는 기능이 내장되어 있으며, 마이크를 사용할 필요가 없고, 휴대하기 쉬운 장점이 있다. 디지털피아노의 키는 어쿠스틱 피아노와 유사한 느낌을 주도록 제작되며, 속도-반응식이어서 연주음의 음량(volume)과 음색(timbre)은 키의 속도에 의존한다. 디지털 피아노는 실제 피아노의 터치와 같은 느낌을 주도록 햄머(hammer)를 가지고 있다. 키의 눌림을 감지하기 위하여 아날로그 센서를 두고 있는데, 이 점이 통상의 전자 키보드나 신디사이저와 다른 점이다. 일부 디지털피아노는 페달을 내장하고 있기도 하지만, 어쿠스틱 피아노와 같이 공명을 위하여 페달을 눌러 댐퍼를 조정하는 기능을 갖춘 것은 매우 고가이다. Digital pianos have the advantages of lower maintenance costs than acoustic pianos, sound implemented in MIDI, built-in functions to help learning and composition, no need to use a microphone, and easy portability. The keys of the digital piano are designed to give a feeling similar to that of an acoustic piano, and are velocity-responsive, so the volume and timbre of the sound played depend on the velocity of the keys. Digital pianos have hammers to give the same feel as the touch of a real piano. An analog sensor is placed to detect the pressing of a key, which is different from a typical electronic keyboard or synthesizer. Some digital pianos have built-in pedals, but those equipped with a function of adjusting the damper by pressing the pedal for resonance, such as an acoustic piano, are very expensive.
특허 제10-1014809호는 디지털 피아노의 건반 구조를 제시하고 있다. 도 1에 도시한 것과 같이, 디지털 피아노의 건반구조는, 건반(130')이 수용되는 프레임(120'), 건반(130')에 회동가능하게 설치되는 해머(140') 및 해머(140')의 회동점에 인접되게 설치되는 러버스위치(Rubber Switch, 150')로 구성된다. 건반모듈은 1옥타브를 하나의 모듈로 하여 일정간격으로 나란하게 배치되어 7옥타브를 이룬다.Patent No. 10-1014809 suggests a keyboard structure of a digital piano. As shown in FIG. 1, the keyboard structure of the digital piano includes a frame 120' accommodating a keyboard 130', a hammer 140' rotatably installed in the keyboard 130', and a hammer 140'. ) It is composed of a rubber switch (150') installed adjacent to the pivot point. The keyboard modules are arranged side by side at regular intervals with one octave as one module to form 7 octaves.
현재 디지털피아노의 전자적 구조를 보면, 도 2에 도시한 것과 같이, 복수의 건반에 대응하여 설치된 각각의 슬레이브(slave) 보드(S')를 1부터 n까지 n개 배열하고, 각각의 슬레이브 보드(S1', S2', …Sn')를 시리즈로 연결하고 이것을 하나의 마스터 보드(M')에 연결한 구조를 취하고 있다. 건반이 눌리는 경우, 마스터보드(M')는, 눌린 건반을 관할하는 슬레이브 보드의 고유 코드와 슬레이브 보드가 전송한 건반 고유 코드를 식별하고, 이에 대응하는 음을 메모리에서 판독하고, 음량 송출부를 통하여 외부 출력 장치로 출력한다.Looking at the electronic structure of the current digital piano, as shown in FIG. S1', S2', ...Sn') are connected in series and connected to one master board (M'). When a key is pressed, the master board (M') identifies the unique code of the slave board governing the pressed key and the unique code of the key transmitted by the slave board, reads the corresponding sound from the memory, and transmits the sound through the volume transmission unit. output to an external output device.
하지만 이 방법에 의하면, 마스터보드(M')가, 건반이 눌린 슬레이브 보드와 건반의 고유 코드를 모두 식별해야 하므로 부하가 커지는 단점이 있다. 또, 디지털 피아노의 연주 시, 동일한 슬레이브 보드에서 건반의 위치만이 달라지는 경우가 많은데 이 경우에도 매번 마스터 보드가 슬레이브 보드를 처음부터 다시 인식하는 것은 비효율적이다.However, according to this method, there is a disadvantage in that the load increases because the master board M' has to identify both the slave board on which the key is pressed and the unique code of the key. In addition, when playing a digital piano, there are many cases in which only the position of the keys on the same slave board is changed. Even in this case, it is inefficient for the master board to recognize the slave board again from the beginning each time.
디지털 피아노의 전자적 기능과 관련하여, 특허 공개 제10-2007-0035340호는 건반키패드와, 음향들이 저장된 메모리와, 건반키패드의 특정 건반 입력시, 발생되는 압력의 세기를 감지하여 출력하는 압력감지부를 두어 음량의 크기를 조절하는 내용을 제안하고 있다. 또, 특허공개 제10-2016-59281호 디지털 피아노 또는 마스터 키보드와 연결되어 연동 가능한 전자 기기가, 피아노 연주 연습을 위한 어플리케이션이 실행되는 디바이스, 디바이스와 유무선 통신망을 통해 통신하며, 디바이스의 요청에 따라 어플리케이션의 실행에 필요한 관련 데이터를 제공하는 웹 서버, 어플리케이션에 관련된 데이터를 저장하고 있으며, 웹 서버의 요청에 따른 관련 데이터를 웹 서버에 제공하는 DB 서버를 포함하는 디지털 피아노를 제공하고 있다.Regarding the electronic function of the digital piano, Patent Publication No. 10-2007-0035340 discloses a keyboard keypad, a memory in which sounds are stored, and a pressure sensor for detecting and outputting the intensity of pressure generated when a specific key is input on the keyboard keypad. It is proposed to adjust the size of the volume. In addition, Patent Publication No. 10-2016-59281 connects an electronic device that can be linked to a digital piano or master keyboard, communicates with a device running an application for piano playing practice, and a device through a wired or wireless communication network, and according to the request of the device We provide a digital piano that includes a web server that provides data necessary for the execution of applications, and a DB server that stores data related to applications and provides data to the web server according to requests from the web server.
그러나, 상기 특허는 디지털피아노의 건반, 또는 디지털 피이노의 외부기기나 서버와의 무선 통신에 관한 것이며, 디지털 피아노에 특유한 마스터 및 슬레이브 보드의 문제에는 착안하고 있지 않다. 이 문제가 해결된다면 건반의 고유음 발현이나 외부 기기 및 서버와의 통신에도 향상을 이룰 수 있을 것이다.However, the above patent relates to wireless communication with the keyboard of a digital piano or an external device or server of a digital piano, and does not focus on the problem of master and slave boards specific to digital pianos. If this problem is solved, it will be possible to improve the expression of the unique sound of the keyboard or communication with external devices and servers.

본 발명에 따른 각 실시예는 본 발명의 이해를 돕기 위한 하나의 예에 불과하고, 본 발명이 이러한 실시예에 한정되는 것은 아니다. 본 발명은 각 실시예에 포함되는 개별 구성 및 개별 기능 중, 적어도 어느 하나 이상의 조합으로 구성될 수 있다.Each embodiment according to the present invention is only one example to aid understanding of the present invention, and the present invention is not limited to these embodiments. The present invention may be composed of a combination of at least one or more of individual components and individual functions included in each embodiment.
도 3은 본 발명의 디지털 피아노(1)의 전자 시스템(10)의 구조도이다.3 is a structural diagram of the electronic system 10 of the digital piano 1 of the present invention.
본 발명의 전자 시스템(10)은 하나의 마스터 보드(M)와, 제1, 제2, …, 제n 슬레이브 보드(S1, S2, …, Sn)를 포함하는 슬레이브 모듈(S)로 이루어진다. 각각의 슬레이브 보드(S1, S2, …, Sn)는 시리즈로 연결되며, 제1슬레이브 보드(S1)가 직접 마스터 보드(M)와 연결된다. 각각의 슬레이브 보드(S1, S2, …, Sn)에는 관할하는 각각의 건반(100)이 전기적 및 구조적으로 연결된다. 건반의 수는 12개, 24개 또는 적절한 숫자로 분할하여 만들 수 있다. 이 점에서 본 발명의 디지털 피아노(1)는 복수의 블록(block)으로 이루어지는 피아노라고 할 수 있다.The electronic system 10 of the present invention includes one master board (M), first, second, ... , a slave module S including an n-th slave board (S1, S2, ..., Sn). Each slave board (S1, S2, ..., Sn) is connected in series, and the first slave board (S1) is directly connected to the master board (M). Each of the keyboards 100 in charge is electrically and structurally connected to each slave board (S1, S2, ..., Sn). The number of keys can be made by dividing them into 12, 24 or any suitable number. In this respect, the digital piano 1 of the present invention can be said to be a piano composed of a plurality of blocks.
각각의 슬레이브 보드(S1, S2, …, Sn)에는 각각의 제어부(C1, C2, … , Cn)가 설치된다. 또, 각각의 슬레이브 보드(S1, S2, …, Sn)에는 각각의 제어부(C1, C2, … , Cn)와 연결된 반도체 소자(D1, D2, … , Dn)가 설치된다. 반도체 소자(D1, D2, … , Dn)는 도시한 것과 같이 제1슬레이브 보드(S1)에서 제n슬레이브 보드(Sn)까지 라인(L)에 의해 연결된다. 라인(L)이 예를 들어 5V의 디지컬 피아노(1) 구동용 외부 전원에 연결된 경우라면, 각각의 반도체 소자(D1, D2, … , Dn)에 인가되는 전압이 다르게 된다. 예를 들어 반도체 소자가 다이오드인 경우 고유 내부 저항에 의하여 전압값이 D1, D2, …, Dn으로 갈수록 증가한다. Each of the control units C1, C2, ..., Cn is installed on each slave board S1, S2, ..., Sn. In addition, semiconductor elements D1, D2, ..., Dn connected to respective controllers C1, C2, ..., Cn are installed on each slave board S1, S2, ..., Sn. As illustrated, the semiconductor elements D1, D2, ..., Dn are connected from the first slave board S1 to the nth slave board Sn by a line L. If the line L is connected to, for example, a 5V external power source for driving the digital piano 1, voltages applied to the respective semiconductor elements D1, D2, ..., Dn are different. For example, if the semiconductor device is a diode, the voltage values are D1, D2, ... , which increases as Dn increases.
본 발명에서는 각각의 슬레이브 보드(S1, S2, …, Sn)의 제어부(C1, C2, … , Cn)가 반도체 소자(D1, D2, … , Dn)에 걸리는 전압값을 실시간으로 검출하고 인식한다. 제어부(C1, C2, … , Cn)는 도시하지 않는 각각의 메모리를 참조한다. 메모리에는 자신의 슬레이브 보드에 대응하는 고유 전압값이 저장되어 있다 따라서, 각각의 슬레이브 보드(S1, S2, …, Sn)는 제어부(C1, C2, … , Cn)를 통하여 항상 자신의 고유 코드(Ak)를 알 수 있다. k는 1, 2, …n 중의 하나이며, 자신이 몇 번째 슬레이브 보드인지를 알려주는 코드라고 할 수 있다.In the present invention, the controller (C1, C2, ..., Cn) of each slave board (S1, S2, ..., Sn) detects and recognizes the voltage value applied to the semiconductor element (D1, D2, ..., Dn) in real time. . The control units C1, C2, ..., Cn refer to respective memories not shown. A unique voltage value corresponding to its own slave board is stored in the memory. Therefore, each slave board (S1, S2, ..., Sn) always has its own unique code ( Ak) can be found. k is 1, 2, ... It is one of n, and it can be said that it is a code that informs which slave board it is.
기존 기술과 동일하게, 각각의 슬레이브 보드(S1, S2, …, Sn)의 제어부(C1, C2, … , Cn)는 관할하는 건반에서 어떤 특정 건반이 눌렸는지를 인식한 고유 건반 코드(Bj)를 저장하고 있다. 블록마다 건반이 12개이면 j = 1, 2, …, 12중의 하나가 될 것이다. As in the existing technology, the controllers (C1, C2, ..., Cn) of each slave board (S1, S2, ..., Sn) recognizes which specific key is pressed in the controlled keyboard, and generates a unique key code (Bj) is storing If there are 12 keys per block, j = 1, 2, … , will be one of 12.
마스터 보드(M)에도 고유의 반도체 소자(D0)가 설치되며, 이것은 마스터보드(M)의 MCU(20)와 연결된다. 하지만 마스터 보드(M)는 하나이므로 슬레이브 보드만큼 자기 고유 코드를 부여할 필요는 크지 않으며, 따라서 본 발명의 필수 요건은 아니라고 할 수 있다.A unique semiconductor device (D0) is also installed on the master board (M), which is connected to the MCU (20) of the master board (M). However, since there is only one master board (M), the need to assign its own code is not as great as that of the slave board, and therefore, it is not an essential requirement of the present invention.
다시, 도 3을 참조하면 본 발명의 각각의 슬레이브 보드(S1, S2, …, Sn)는 각각의 전송라인(T1, T2, …, Tn)을 통하여 마스터보드(M)의 MCU(20)와 연결된다. 각각의 슬레이브 보드(S1, S2, …, Sn)는 자신에게 할당된 전송라인을 통하여 슬레이브 보드 고유 코드와 건반 고유 코드, 즉 (Ak, Bj) 데이터를 MCU(20)로 전송한다. 그러면, 마스터 보드(M)는 데이터의 수신만으로 어떤 건반이 눌렸는지를 바로 인식할 수 있어 마스터 보드(M)의 부하를 줄일 수 있으며, 건반의 눌림과 동시에 이에 해당하는 음을 정확히 실시간으로 외부로 송출할 수 있게 된다.Again, referring to FIG. 3, each slave board (S1, S2, ..., Sn) of the present invention connects to the MCU (20) of the master board (M) through each transmission line (T1, T2, ..., Tn). Connected. Each of the slave boards (S1, S2, ..., Sn) transmits the slave board unique code and keyboard unique code, that is, (Ak, Bj) data to the MCU 20 through the transmission line assigned to it. Then, the master board (M) can immediately recognize which key is pressed only by receiving the data, thereby reducing the load on the master board (M), and at the same time as the key is pressed, the corresponding sound is accurately transmitted to the outside in real time. be able to send out.
슬레이브 고유 코드는 반드시 능동적으로 판독되어야 하는 데이터를 의미하는 것은 아니며 예를 들어 이하 설명하는 것과 같이 데이터의 송수신 경로에 따라 전환되는 신호를 포함하는 넓은 개념이다.The slave specific code does not necessarily mean data to be actively read, but is a broad concept including, for example, a signal that is converted according to a transmission/reception path of data as described below.
이상 설명을 구현한 블록형 디지털 피아노(1)의 전자회로의 실례를 도 4및 도 5를 참조로 상세히 설명한다. 슬레이브 보드는 3개인 경우를 전제로 도면4에서는 제1슬레이브 보드(S1)를, 도 5에서는 도 4의 제1슬레이브 보드(S1)와 바로 연결되는 제2슬레이브 보드(S2)를 도시하였다. 슬레이브 보드(S1, S2)의 외관 구성은 동일하다.An example of an electronic circuit of the block type digital piano 1 implementing the above description will be described in detail with reference to FIGS. 4 and 5 . Assuming that there are three slave boards, FIG. 4 shows a first slave board S1 and FIG. 5 shows a second slave board S2 directly connected to the first slave board S1 of FIG. 4 . The external configuration of the slave boards S1 and S2 is the same.
마스터보드(M)와 슬레이브 보드(S1, S2)는 각각 커넥터(30)에 의하여 접속되어 전기적 연결을 이룬다. 마스터보드(M)와 슬레이브 보드(S1, S2)에는 각각의 반도체 소자(D0, D1, D2)가 설치되는데, 도시한 것과 같이 반도체 소자들은 커넥터(30)의 접속으로 라인(L)에 의하여 나란히 일관되게 연결된다. 반도체 소자들은 자신의 또는 다른 보드의 다른 회로나 소자에 관계 없이 독립하여 서로 시리즈로 접속하므로, 슬레이브 보드 각각에 특유한 검출치(전압치)를 오차 없이 정확하게 검출할 수 있다.The master board (M) and the slave boards (S1, S2) are each connected by a connector 30 to form an electrical connection. Each semiconductor device (D0, D1, D2) is installed on the master board (M) and the slave boards (S1, S2). As shown, the semiconductor devices are connected side by side by a line (L) through the connection of the connector (30). connected consistently. Since the semiconductor elements are independently connected to each other in series regardless of their own or other circuits or elements of other boards, detection values (voltage values) specific to each slave board can be accurately detected without errors.
제1슬레이브 보드(S1)의 제어부(C1)는 위에서부터 차례로 송수신라인이 쌍을 이루어 배열된, 제1수신라인(500), 제1송신라인(502), 제2수신라인(504), 제2송신라인(506), 제3수신라인(508) 및 제3송신라인(510)을 포함한다. 각각의 라인을 통하여 데이터를 수신 또는 송신한다. 또, 이에 대응하여 스위치를 제어하기 위한 제1수신스위치제어부(300), 제1송신스위치제어부(302), 제2수신스위치제어부(304), 제2송신스위치제어부(306), 제3수신스위치제어부(308) 및 제3송신스위치제어부(310)가 설치된다.The control unit C1 of the first slave board S1 includes a first receiving line 500, a first transmitting line 502, a second receiving line 504, a second receiving line 500, a first receiving line 502, a second receiving line 504, and a second receiving line 500, in which transmission and reception lines are arranged in pairs in order from the top. It includes a second transmission line 506, a third reception line 508 and a third transmission line 510. Data is received or transmitted through each line. In addition, the first reception switch control unit 300, the first transmission switch control unit 302, the second reception switch control unit 304, the second transmission switch control unit 306, and the third reception switch for controlling the switch corresponding thereto. A control unit 308 and a third transmission switch control unit 310 are installed.
제어부(C1)의 옆에 배열된 스위치는 모두 6개이며, 위에서부터 차례로 제1수신스위치(400), 제1송신스위치(402), 제2수신스위치(404), 제2송신스위치(406), 제3수신스위치(408) 및 제3송신스위치(410)로 이루어진다. 각각의 스위치의 구조는 동일한데, 평소에는 NC(normally closed)와 접하는 것이 디폴트이지만, 슬레이브 보드가 자신의 고유 코드를 인식하면 NO(normally open)와 접하도록 전환된다.A total of six switches are arranged next to the control unit C1, and in order from the top, the first receive switch 400, the first transmit switch 402, the second receive switch 404, and the second transmit switch 406 , a third receiving switch 408 and a third transmitting switch 410. The structure of each switch is the same. Normally, it defaults to contact NC (normally closed), but when the slave board recognizes its own code, it is converted to contact NO (normally open).
구체적으로, 슬레이브 보드(S1)가 자신의 고유 코드(A1)를 인식하면, 제1 수신 및 송신스위치제어부(300, 302)를 구동하여 제1수신 및 송신스위치(400, 402)가 NO와 접하며, 따라서, 제1수신 및 송신라인(500, 502)이 마스터 보드(M)와 데이터 송수신이 가능하다. 제1송신라인(502)을 통하여 마스터 보드(M)로 제1슬레이브의 데이터를 전송할 수 있다. 반대로, 마스터 보드(M)로부터 제1수신라인(500)을 통하여 제1슬레이브 보드(S1)에 필요한 데이터를 수신 받을 수 있다.Specifically, when the slave board S1 recognizes its own code A1, the first reception and transmission switch controllers 300 and 302 are driven so that the first reception and transmission switches 400 and 402 come into contact with NO. Therefore, the first receiving and transmitting lines 500 and 502 can transmit and receive data with the master board M. Data of the first slave may be transmitted to the master board M through the first transmission line 502 . Conversely, data necessary for the first slave board S1 can be received from the master board M through the first receiving line 500 .
이때, 제1슬레이브 보드(S1)의 남은 4개의 스위치는 NC를 통하여 마스터 보드(M)와 연결되어 NO를 통한 전송 루트와 구별되므로, 마스터 보드(M)는 제1슬레이브 보드(S1)로부터의 신호임을 신속하고 용이하게 인식할 수 있다. 이 과정은 자연스럽게 제1슬레이브 보드의 고유 코드를 마스터 보드(M)가 인식하는 과정이 된다.At this time, the remaining four switches of the first slave board (S1) are connected to the master board (M) through NC and distinguished from the transmission route through NO, so the master board (M) is connected to the master board (M) from the first slave board (S1). It can be quickly and easily recognized as a signal. This process naturally becomes a process in which the master board M recognizes the unique code of the first slave board.
제2슬레이브 보드(S2)는 제1슬레이브 보드(S1)와 동일하지만, 슬레이브 보드(S2)가 자신의 고유 코드(A2)를 인식하면, 제2 수신 및 송신스위치제어부(304, 306)를 구동하여 제2수신 및 송신스위치(404, 406)가 NO와 접하며, 남은 4개의 스위치는 NC를 통하여 마스터 보드(M)와 연결되어 NO를 통한 전송 루트와 구별되므로, 마스터 보드(M)는 용이하게 제2슬레이브 보드(S2)로부터의 신호임을 인식할 수 있다(도 5 참조).The second slave board (S2) is the same as the first slave board (S1), but when the slave board (S2) recognizes its own code (A2), it drives the second reception and transmission switch controllers (304, 306). Therefore, the second receiving and transmitting switches 404 and 406 are in contact with NO, and the remaining four switches are connected to the master board M through NC and distinguished from the transmission route through NO, so the master board M can be easily It can be recognized that the signal is from the second slave board S2 (see FIG. 5).
당업자는 이와 같은 방법으로 3개 또는 그 이상의 슬레이브 모듈을 계속하여 구축할 수 있음을 이해할 것이다. One skilled in the art will understand that it is possible to construct three or more slave modules in succession in this manner.
즉 복수의 슬레이브 보드를 마스터 보드에 연결하고 전원을 인가하면 제1슬레이브 보드는 그에 고유한 스위치(400, 402)가 NO로 되고, 나머지 스위치는 NC가 되며, 제2슬레이브 보드는 그에 고유한 스위치(404, 406)가 NO로 되고, 나머지 스위치는 NC가 되며, 제3슬레이브 보드는 그에 고유한 스위치(408, 410)가 NO로 되고, 나머지 스위치는 NC가 되므로, 마스터 보드는 동시에 각각의 슬레이브 보드를 자동으로 명확히 인식할 수 있는 것이다.That is, when a plurality of slave boards are connected to the master board and power is applied, the switches 400 and 402 unique to the first slave board become NO, the other switches become NC, and the second slave board has its own switches (404, 406) become NO, the remaining switches become NC, the third slave board has its own switches 408, 410 become NO, and the remaining switches become NC, so the master board simultaneously The board can be clearly recognized automatically.
슬레이브 보드를 n개 배열하면, 각각의 슬레이브 보드의 스위치는 2n개가 될 것이다. 각각의 슬레이브 보드의 외관상 구조는 동일해 보이지만, 슬레이브 보드의 자기 인식에 따라 마스터 보드에 전달되는 데이터가 상이함을 이해할 수 있을 것이다.If n slave boards are arranged, each slave board will have 2n switches. Although the external structure of each slave board looks the same, it will be understood that data transmitted to the master board is different according to self-recognition of the slave board.
도 4는 회로도의 일례를 도시한 것이며, 각각의 슬레이브 보드에는 이와 연관되는 스위치만을 두고 나머지 스위치는 삭제하는 등 당업자 수준에서 다양한 변경이 가능함은 물론이다.FIG. 4 shows an example of a circuit diagram, and various changes are possible at the level of those skilled in the art, such as leaving only switches related thereto in each slave board and deleting the remaining switches.
이상 본 발명의 실시예를 설명하였으나, 이는 본 발명을 한정하지 않으며 본 발명에 대해서는 다양한 변형과 수정이 가능하다. Although the embodiments of the present invention have been described above, this does not limit the present invention and various modifications and variations are possible for the present invention.
본 발명의 권리범위는 이하 기술하는 청구범위와 동일 또는 균등한 범위까지 미침은 자명하다.It is obvious that the scope of the present invention extends to the same or equivalent scope as the claims described below.
