Description
本発明は、耐圧防爆機器に関するものである。
更に詳述すれば、耐圧防爆機器のキー操作部分に関するものである。
The present invention relates to a flameproof device.
More specifically, the present invention relates to the key operation part of the explosion-proof equipment.
従来の耐圧防爆機器は耐圧防爆構造を維持した状態で、機器を操作する必要があるために、下記のような方式を採用している。 Since the conventional explosion-proof equipment needs to operate the equipment while maintaining the explosion-proof construction, the following method is adopted.
図4は従来より一般に使用されている従来例の要部構成説明図で、キー操作にメカニカルスイッチを使う場合である。
図において、1はプリント基板、2はプリント基板1に取り付けられたプッシュスイッチ、3はプッシュスイッチ2に取り付けられたシャフト、4は耐圧防爆機器の容器の壁である。
FIG. 4 is an explanatory view of the configuration of the main part of a conventional example that is generally used in the past, and shows a case where a mechanical switch is used for key operation.
In the figure, 1 is a printed circuit board, 2 is a push switch attached to the printed circuit board 1, 3 is a shaft attached to the push switch 2, and 4 is a wall of a container of the explosion-proof equipment.
以上の構成において、耐圧防爆機器の容器の壁4に配置されたシャフト3を通して、耐圧防爆機器の内部のプッシュスイッチ2を押すことで耐圧防爆機器を操作する。 In the above configuration, the explosion-proof device is operated by pressing the push switch 2 inside the explosion-proof device through the shaft 3 disposed on the wall 4 of the container of the explosion-proof device.
図5は従来より一般に使用されている他の従来例の要部構成説明図で、キー操作に光スイッチを使う場合である。
図において、11はプリント基板、12はプリント基板11に取り付けられた光スイッチ、13は耐圧防爆機器の容器の壁14に設けられたガラスである。
以上の構成において、ガラス13を通して、指の光反射で光スイッチを動かすことで耐圧防爆機器を操作する。
FIG. 5 is an explanatory diagram showing the structure of the main part of another conventional example that is generally used in the prior art, and shows a case where an optical switch is used for key operation.
In the figure, 11 is a printed circuit board, 12 is an optical switch attached to the printed circuit board 11, and 13 is glass provided on the wall 14 of the container of the explosion-proof equipment.
In the above configuration, the explosion-proof equipment is operated by moving the optical switch through the glass 13 by the light reflection of the finger.
このような装置においては、以下の問題点がある。
シャフトを使用するプッシュスイッチ方式は、耐圧防爆構造を維持しなければならないので、機構が複雑になる。
光スイッチを使用すると、誤動作、操作感が悪い等の操作性が悪い。ハードが非防爆機器に対して大きく変わる。
Such an apparatus has the following problems.
The push switch system using a shaft requires a pressure-proof explosion-proof structure, which complicates the mechanism.
When an optical switch is used, operability such as malfunction and poor operation feeling is poor. The hardware changes greatly for non-explosion-proof equipment.
本発明の目的は、上記の課題を解決するもので、構造が簡潔にでき、操作性が良好なHMI(ヒューマン・マシン・インターフェイス)が出来る耐圧防爆機器を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a flameproof device capable of providing a HMI (Human Machine Interface) having a simple structure and good operability.
このような課題を達成するために、本発明では、請求項1の耐圧防爆機器においては、
内部の電気火花により可燃性ガスに引火しても外部へ火炎を漏らさずに誘爆を防ぐ耐圧防爆機器において、前記耐圧防爆機器本体ケースに設けられた光学レンズを有するQRコード読み取り部と、前記耐圧防爆機器本体ケース内に設けられ前記QRコード読み取り部を介してQRコードを読み取るCCD部と、このCCD部で読み取った信号を受け取るQRコード識別部とを具備したことを特徴とする。
In order to achieve such a problem, in the present invention, in the explosion-proof equipment of claim 1,
In a flameproof device that prevents explosion without leaking the flame to the outside even when flammable gas is ignited by an internal electric spark, a QR code reading unit having an optical lens provided in the flameproof device body case, and the pressure resistance A CCD unit provided in an explosion-proof device main body case for reading a QR code via the QR code reading unit and a QR code identification unit for receiving a signal read by the CCD unit are provided.
本発明の請求項1によれば、次のような効果がある。
耐圧防爆機器において、構造が簡潔にでき、操作性が良好なHMI(ヒューマン・マシン・インターフェイス)が出来る耐圧防爆機器が得られる。
本体機器に、QRコード読み取り機構を追加すればよく、内部回路は非防爆機器とほとんど共通化できるので、安価な耐圧防爆機器が得られる。
According to claim 1 of the present invention, there are the following effects.
In the explosion-proof device, the explosion-proof device can be obtained in which the structure can be simplified and the HMI (human machine interface) with good operability can be obtained.
A QR code reading mechanism may be added to the main device, and the internal circuit can be almost shared with non-explosion-proof devices, so an inexpensive explosion-proof device can be obtained.
手が汚れている、あるいは手袋をしている等のように機器に直接触れて操作できない場合に、機器の操作を確実に操作できる耐圧防爆機器が得られる。
QRコードを使用しなければならないので、セキュリティ効果が確保できる耐圧防爆機器が得られる。
In the case where the device cannot be operated by directly touching the device, such as when the hands are dirty or wearing gloves, a flameproof device capable of reliably operating the device is obtained.
Since a QR code must be used, a flameproof device that can ensure a security effect is obtained.
QRコード読み取り部は光学レンズが使用されたので、占有面積を小さく出来、耐圧防爆に好適な耐圧防爆機器が得られる。
Since an optical lens is used for the QR code reading unit , the occupation area can be reduced, and a flameproof device suitable for flameproofing can be obtained.
