Abstract
Description
本発明は、石油ファンヒーターに使用する回路基板に関するものである。 The present invention relates to a circuit board used for an oil fan heater.
石油ファンヒーターは、灯油等の燃料を制御して燃焼を行うものであり、その構造は電気ヒーターより複雑であり、制御を行う回路基板も大型となる。そのため一般的には表示や操作を行う操作基板と、本体の制御を行う制御基板との２枚に分かれ、操作基板は人が操作しやすい例えば機器本体の上部表面に配置され、制御基板は機器本体の内部に配置される。 The oil fan heater controls the fuel such as kerosene and performs combustion, and its structure is more complicated than that of the electric heater, and the circuit board to be controlled becomes large. Therefore, it is generally divided into an operation board that performs display and operation and a control board that controls the main body, and the operation board is arranged on the upper surface of the apparatus main body, which is easy for humans to operate. Arranged inside the body.
また、燃焼制御はＣＰＵによって行われるが、このＣＰＵは比較的基板サイズに制約が少なく、複雑な燃焼制御を行う部品が配置された制御基板側に搭載される。 Combustion control is performed by a CPU, and this CPU is mounted on the control board side on which components for performing complicated combustion control are arranged with relatively few restrictions on the board size.
操作基板は、ＬＣＤ、ＬＥＤランプ等の表示装置とスイッチ等の入力装置が搭載され、操作パネル内に組み込まれる事が多い。 The operation board is equipped with a display device such as an LCD or LED lamp and an input device such as a switch, and is often incorporated in an operation panel.
操作パネルと制御基板との接続はケーブルによるが、制御基板にのみ搭載されたＣＰＵにより全ての制御を行うため、操作基板に搭載されたＬＣＤ、ＬＥＤランプ等の表示装置とスイッチ等の入力装置の数に比例して接続ケーブルの本数も必要となり、２０本〜４０本程度と多数の配線を必要としている。また最近は石油ファンヒータも高機能化しており、例えば人感センサーを利用して燃焼を制御したりするものもあり、今後も接続ケーブルの配線本数は増加傾向にある。 The connection between the operation panel and the control board is via a cable, but since all control is performed by a CPU mounted only on the control board, a display device such as an LCD or LED lamp mounted on the operation board and an input device such as a switch are connected. The number of connection cables is also required in proportion to the number, and a large number of wires, such as about 20 to 40, are required. In recent years, oil fan heaters have become more sophisticated, for example, some use a human sensor to control combustion, and the number of connection cables is increasing.
さらに、制御基板にのみ搭載されたＣＰＵにより操作基板と制御基板の両方を制御する関係で、操作パネルの仕様に変更が生じた場合には、操作基板を変更するだけでなく、制御基板も同時に変更する必要があるなど無駄も多い。 Furthermore, when both the operation board and the control board are controlled by a CPU mounted only on the control board, when the specification of the operation panel is changed, not only the operation board is changed, but the control board is simultaneously changed. There is a lot of waste, such as the need to change.
解決しようとする問題点は、石油ファンヒーターの高機能化に比例して操作基板と制御基板との間で必要とする接続線の本数が増加する点と、操作パネルの仕様変更のみであっても、操作基板とその制御を行うＣＰＵが搭載された制御基板の双方を新しくする必要がある点である。 The only problems to be solved are the increase in the number of connection lines required between the operation board and the control board in proportion to the higher functionality of the oil fan heater, and the change in the specifications of the operation panel. Also, it is necessary to renew both the operation board and the control board on which the CPU for controlling the operation board is mounted.
本発明は、操作基板と制御基板との接続ケーブルの配線本数を減らし、操作パネルの仕様変更があったとしても操作基板の変更のみで制御基板が影響されないよう、操作基板と制御基板の双方にＣＰＵを搭載して、このＣＰＵ間をシリアル通信で結ぶ事と、接続ケーブルの配線本数を電源を含み２本から５本とする事を最も主要な特徴とする。 The present invention reduces the number of connection cables between the operation board and the control board, and even if there is a change in the specifications of the operation panel, both the operation board and the control board are not affected by the change of the operation board. The main features are that a CPU is mounted, the CPUs are connected by serial communication, and the number of connection cables is 2 to 5 including the power supply.
操作基板用ＣＰＵと制御基板用ＣＰＵというようにＣＰＵを２つに分ける事により、スマートフォンに採用されているような指先の多点検出が可能なタッチパネルを操作パネルに採用したとしても、タッチパネルの複雑な制御は操作パネル側の操作基板に搭載されたＣＰＵが全て行い、操作の結果のみ制御基板のＣＰＵにシリアル通信で伝えれば良く、例えば従来の操作パネルから最新型のタッチパネルに操作パネルを変更したとしても、シリアル通信でつながっているのであれば制御基板を変更する必要がないという利点がある。 Even if a touch panel capable of multipoint detection of fingertips, such as those used in smartphones, is used for the operation panel by dividing the CPU into two, such as an operation board CPU and a control board CPU, the touch panel is complicated. All control is performed by the CPU mounted on the operation board on the operation panel side, and only the result of the operation needs to be communicated to the control board CPU via serial communication. For example, the operation panel has been changed from the conventional operation panel to the latest touch panel. However, there is an advantage that it is not necessary to change the control board if it is connected by serial communication.
操作基板と制御基板をシリアル通信で結び、配線本数を２本から５本とすると共に、操作基板の仕様が変更となっても制御基板を共通で利用できるという目的を、最小の部品点数で実現した。 The operation board and the control board are connected by serial communication, and the number of wiring is reduced from 2 to 5, and the purpose of using the control board in common even if the specifications of the operation board are changed is realized with the minimum number of parts. did.
図１は、本発明装置の１実施例のブロック図であって、１は操作パネル、２は操作基板、３はＬＣＤ、４はＬＥＤランプ、５はスイッチ、６は操作基板用ＣＰＵ、７はシリアル通信線、８は制御基板、９は制御基板用ＣＰＵである。 FIG. 1 is a block diagram of an embodiment of the apparatus of the present invention, wherein 1 is an operation panel, 2 is an operation board, 3 is an LCD, 4 is an LED lamp, 5 is a switch, 6 is an operation board CPU, and 7 is an operation board. A serial communication line, 8 is a control board, and 9 is a control board CPU.
本発明の主体は、操作基板２と制御基板８との接続方法にあるので、操作基板２と制御基板８の回路の説明とソフトの説明および機構系の説明は省略する。 Since the subject of the present invention is the connection method between the operation board 2 and the control board 8, the explanation of the circuit of the operation board 2 and the control board 8, the explanation of the software, and the explanation of the mechanism system are omitted.
操作パネル１には、ＬＣＤ３、ＬＥＤランプ４、スイッチ５、操作基板用ＣＰＵ６などが搭載された操作基板２が組み込まれているが、操作基板２にＣＰＵを搭載する事により、制御基板８とのシリアル通信が可能となった。 An operation board 2 on which an LCD 3, an LED lamp 4, a switch 5, an operation board CPU 6 and the like are mounted is incorporated in the operation panel 1, but by mounting the CPU on the operation board 2, Serial communication became possible.
従来の基板においても操作基板と制御基板の２枚にわかれていたが、ＣＰＵは制御基板にのみ搭載されているため、操作基板に搭載されたＬＣＤ、ＬＥＤランプ、スイッチの数量に合せた配線が必要となり、操作基板と制御基板との接続には、２０ピンから４０ピンと多極のケーブルが必要であった。 The conventional board was divided into two boards, the operation board and the control board. However, since the CPU is mounted only on the control board, wiring according to the number of LCDs, LED lamps, and switches mounted on the operation board is required. Necessary, and the connection between the operation board and the control board requires a 20-pin to 40-pin cable.
実施例のように操作基板２と制御基板８にそれぞれＣＰＵを搭載した事により、２枚の基板間にてシリアル通信が可能となり、シリアル通信線７を２線式（Ｉ２Ｃ）とする事により電源を含めた接続線の本数を４本とする事ができた。 Since the CPU is mounted on each of the operation board 2 and the control board 8 as in the embodiment, serial communication can be performed between the two boards, and the power supply can be obtained by making the serial communication line 7 two-wire (I2C). The number of connection lines including can be reduced to four.
なお、シリアル通信にはその他、１線式（１−Ｗｉｒｅ）、３線式（ＳＰＩ）などもあるので、シリアル通信線７は２本から５本の本数で構成するのが良い。 Since serial communication includes other one-wire type (1-Wire), three-wire type (SPI), etc., the serial communication line 7 is preferably composed of two to five lines.
制御基板８は石油ファンヒーターの燃焼制御を行うが、燃焼制御の動作シーケンスは基本的に同じであり、例えば操作パネルに人感センサー等の高機能センサーが追加されたとしても燃焼に関わる動作シーケンスは同じであるため、制御基板８は変更する必要がない。つまり操作基板２の仕様が変更となったとしても、シリアル通信線７と制御基板８は交換する必要がなく、そのまま利用できる。 The control board 8 controls the combustion of the oil fan heater, but the operation sequence of the combustion control is basically the same. For example, even if a high-function sensor such as a human sensor is added to the operation panel, the operation sequence related to combustion Are the same, the control board 8 does not need to be changed. That is, even if the specification of the operation board 2 is changed, the serial communication line 7 and the control board 8 do not need to be exchanged and can be used as they are.
図２は、本発明装置の１実施例のブロック図であって、１と２、６から９は実施例１と同様なため説明を省略する。１０はタッチパネルである。 FIG. 2 is a block diagram of an embodiment of the apparatus of the present invention. Since 1 and 2 and 6 to 9 are the same as those of the embodiment 1, their description is omitted. Reference numeral 10 denotes a touch panel.
タッチパネル１０は、表示と入力の２つの機能を備えており、アイコンや画像等をＬＣＤに表示すると共に、ＬＣＤの表面に導電膜が張り付けられており、この導電膜と指先との間での静電容量の変化をとらえて指先の位置を検出し、アイコンや画像等をタッチするとスイッチＯＮとなるような入出力機能を持つ装置である。 The touch panel 10 has two functions of display and input. The touch panel 10 displays icons, images, and the like on the LCD, and a conductive film is pasted on the surface of the LCD. This device has an input / output function that detects a fingertip position by detecting a change in electric capacity and turns on a switch when an icon or image is touched.
本発明の主体は、操作基板２と制御基板８との接続方法にあるので、タッチパネル１０の回路の説明と機構系の説明は省略する。 Since the main body of the present invention is the connection method between the operation board 2 and the control board 8, the explanation of the circuit of the touch panel 10 and the explanation of the mechanism system are omitted.
最近はスマートフォンで採用されているような、指先の動きに連動して視覚的に操作しやすいタッチパネルが一般的になりつつあるが、ＬＣＤはグラフィック表示可能なドットマトリクス方式、導電膜は指先の多点検出を可能とするため縦と横に走る多数の電極列が必要となっている。 Recently, touch panels that are easy to operate visually in conjunction with the movement of the fingertips, such as those used in smartphones, are becoming common, but the LCD is a dot-matrix method that can display graphics, and the conductive film has many fingertips. In order to enable point detection, a large number of electrode rows running vertically and horizontally are required.
従来のような制御基板のみにＣＰＵを搭載して、操作基板と必要な配線本数で結ぶ方法では、タッチパネルの採用は非現実的な設計になってしまう。 In the conventional method in which the CPU is mounted only on the control board and is connected to the operation board with the necessary number of wires, the adoption of the touch panel becomes an unrealistic design.
その点、操作基板２にタッチパネル制御を可能とする操作基板用ＣＰＵ６を搭載し、制御基板８に燃焼制御を行う制御基板用ＣＰＵ９を搭載し、両ＣＰＵ間をシリアル通信で結ぶ方法であれば、タッチパネルの採用は合理的な設計となる。 In that regard, if the operation board CPU 6 that enables touch panel control is mounted on the operation board 2 and the control board CPU 9 that performs combustion control is mounted on the control board 8 and the two CPUs are connected by serial communication, Adopting a touch panel is a rational design.
操作部と制御部それぞれ基板が分かれ接続線で結ばれているような装置であれば、双方の基板にＣＰＵを搭載してシリアル通信を行う事により、接続線の配線本数を減らす用途として適用できる。 If the operation unit and the control unit are separated from each other and are connected by connecting lines, it can be applied as an application to reduce the number of connecting lines by installing a CPU on both boards and performing serial communication. .
