Description

本発明は、電力変換装置の機能選択、数値設定など、運転状態を変更するための操作手段、及び電力変換装置の異常を検出する手段を備え、これらの手段により音を発生させる電力変換装置に関するものである。   The present invention relates to a power converter that includes operation means for changing an operating state, such as function selection and numerical setting of a power converter, and means for detecting an abnormality of the power converter, and generates sound by these means. Is.

従来の電力変換装置は、所要の機能選択と数値設定、及び運転状態等の変更は、電力変換装置に付属の操作装置のキーを押下することにより行われ、押下の際にブザー音を発生させる。また、何らかの原因により予め設定しておいた範囲を超える電流が出力されるなどの異常が起きた場合には、その異常を検出しアラーム音を発生させる。
ブザー音やアラーム音を発生させる際に特許文献１に示されるような技術を用いてブザー音とアラーム音との音量に差を設け、音の大きさでブザー音とアラーム音との区別を行っている。 In the conventional power conversion device, required function selection, numerical setting, and change of operation state, etc. are performed by pressing a key of an operation device attached to the power conversion device, and a buzzer sound is generated at the time of pressing. . In addition, when an abnormality such as output of a current exceeding a preset range for some reason occurs, the abnormality is detected and an alarm sound is generated.
When generating a buzzer sound or an alarm sound, a difference between the buzzer sound and the alarm sound is set using a technique as shown in Patent Document 1, and the buzzer sound and the alarm sound are distinguished by the volume of the sound. ing.

以下、従来の電力変換装置において、操作装置のキー押下時、異常パターンＡ発生時、及び異常パターンＢ発生時にそれぞれブザー音、アラーム音Ａ、アラーム音Ｂを出力する例を図示する。
図３に従来の電力変換装置の実施ブロック図を示す。電力変換装置操作装置のキーを押下すると、キー押下信号がブザー音発生装置へ伝達される。ブザー音発生装置はブザー音を出力し音量調節装置に伝達する。音量調節装置は音量選択装置によって予め設定された音量１の音量を出力する。また、電力変換装置に異常パターンＡが発生すると、異常検出装置が異常を検出し、エラー信号Ａを出力し、アラーム音発生装置はアラーム音Ａを出力し、音量調節装置に伝達する。音量調節装置は音量選択装置によって予め設定された音量２の音量を出力する。同様に異常パターンＢが発生したときには音量３を出力する。
特開２００３−１５０１８０号公報 Hereinafter, in the conventional power conversion device, an example in which a buzzer sound, an alarm sound A, and an alarm sound B are output when a key of the operation device is pressed, when an abnormal pattern A occurs, and when an abnormal pattern B occurs is illustrated.
FIG. 3 shows an implementation block diagram of a conventional power converter. When a key of the power converter operation device is pressed, a key press signal is transmitted to the buzzer sound generator. The buzzer sound generator outputs a buzzer sound and transmits it to the volume control device. The volume control device outputs a volume of volume 1 set in advance by the volume selection device. When an abnormal pattern A occurs in the power conversion device, the abnormality detection device detects an abnormality and outputs an error signal A. The alarm sound generation device outputs an alarm sound A and transmits it to the volume control device. The volume control device outputs a volume 2 that is preset by the volume selection device. Similarly, when an abnormal pattern B occurs, volume 3 is output.

しかしながら、このような従来の電力変換装置では、運転者が電力変換装置から離れて監視する場合や、運転者が電力変換装置により駆動される交流電動機などが発生する騒音の中にいる場合においては差異を設けたブザー音やアラーム音のうち相対的に音量が小さいものが聞こえにくいという問題があった。例えば、運転者にブザー音が聞こえないと運転者はキーを押下したのかどうかが分かりにくい。また運転者にアラーム音が聞こえなかった場合は異常発生を感知することができず、重大な事故を招く危険性がある。   However, in such a conventional power conversion device, when the driver monitors away from the power conversion device, or when the driver is in the noise generated by the AC motor driven by the power conversion device, etc. There is a problem that it is difficult to hear a relatively low volume of the buzzer sound or the alarm sound with a difference. For example, if the driver does not hear a buzzer sound, it is difficult to know whether the driver has pressed a key. Also, if the driver does not hear the alarm sound, it cannot detect the occurrence of an abnormality and may cause a serious accident.

一方、この問題を解決すべくブザー音やアラーム音の絶対的な音量を大きく設定すると、運転者が電力変換装置の近くで監視する場合や、電力変換装置の運転者が電力変換装置により駆動される交流電動機などが発生する騒音の外にいる場合においては、ブザー音とアラーム音のうち相対的に音量の大きな音が騒音となり、運転者に不快感を感じさせるという問題もある。   On the other hand, if the absolute volume of the buzzer sound or alarm sound is set to be large to solve this problem, the driver monitors the power converter, or the driver of the power converter is driven by the power converter. When the AC motor is outside the generated noise, a relatively loud sound of the buzzer sound and the alarm sound becomes noise, which causes the driver to feel uncomfortable.

従来技術における以上の問題点に鑑み、本発明では電力変換装置の運転状態を変更する操作を行った場合にブザー音を、電力変換装置が異常を来たした場合にアラーム音を、それぞれ発生させるにあたり、前記ブザー音と前記アラーム音の音量調節を、同音量にて行うようにした。
また、電力変換装置の運転状態を変更する操作を行った場合にブザー音を、電力変換装置が異常を来たした場合にアラーム音を、それぞれ発生させるにあたり、前記ブザー音と前記アラーム音の音量調節を、予め定められた所定比にて行うようにしてもよいし、この所定比を調整するようにしてもよい。 In view of the above problems in the prior art, the present invention generates a buzzer sound when an operation for changing the operating state of the power conversion device is performed, and an alarm sound when the power conversion device is abnormal. In this case, the volume of the buzzer sound and the alarm sound is adjusted at the same volume.
In addition, a buzzer sound is generated when an operation to change the operating state of the power converter is performed, and an alarm sound is generated when the power converter has an abnormality, and the buzzer sound and the volume of the alarm sound are generated. The adjustment may be performed at a predetermined ratio, or the predetermined ratio may be adjusted.

本発明によれば、電力変換装置におけるブザー音やアラーム音の音量調節を、個別に行うという煩雑を解消することができる。さらに電力変換装置の使用環境にあわせた音量設定をも行うことができる。   ADVANTAGE OF THE INVENTION According to this invention, the complexity which performs the volume adjustment of a buzzer sound and an alarm sound in a power converter device separately can be eliminated. Furthermore, the sound volume can be set according to the usage environment of the power converter.

図１に本発明の第１の実施形態を示す。電力変換装置の操作装置のキーを押下すると、キー押下信号がブザー音を出力して音量調節装置に伝達される。ブザー音発生装置はブザー音を出力して音量調節装置に伝達する。音量調節装置は音量選択装置によって予め一括して設定された音量４の音量を出力する。また、電力変換装置に異常パターンＡが発生すると異常検出装置が異常を検出し、エラー信号Ａを出力し、アラーム音発生装置に伝達する。アラーム音発生装置はアラーム音Ａを出力し、音量調節装置に伝達する。音量調節装置は音量選択装置によって予め一括して設定された音量４の音量を出力する。同様に異常パターンＢが発生したときも音量４を出力する。   FIG. 1 shows a first embodiment of the present invention. When a key on the operating device of the power conversion device is pressed, a key pressing signal is output to the volume control device by outputting a buzzer sound. The buzzer sound generator outputs a buzzer sound and transmits it to the volume control device. The volume control device outputs the volume 4 set in advance by the volume selection device. Further, when an abnormal pattern A occurs in the power conversion device, the abnormality detection device detects an abnormality, outputs an error signal A, and transmits it to the alarm sound generation device. The alarm sound generator outputs an alarm sound A and transmits it to the volume control device. The volume control device outputs the volume 4 set in advance by the volume selection device. Similarly, when the abnormal pattern B occurs, the volume 4 is output.

図２に本発明の第２の実施形態を示す。電力変換装置の操作装置のキーを押下すると、キー押下信号がブザー音発生装置へ伝達される。ブザー音発生装置はブザー音を出力し、音量調節装置に伝達する。音量調節装置は音量選択装置によって予め一括して設定された音量１の音量を、音量比率選択装置によって予め設定された１：５という比率に従って、音量１を出力する。また、電力変換装置に異常パターンＡが発生すると、異常検出装置が異常を検出し、エラー信号Ａを出力し、アラーム音発生装置に伝達する。アラーム音発生装置はアラーム音Ａを出力し、音量調節装置に伝達する。音量調節装置は音量選択装置によって予め設定された１：５という比率に従って、音量５を出力する。同様に異常パターンＢが発生したときも音量５を出力する。   FIG. 2 shows a second embodiment of the present invention. When a key on the operating device of the power conversion device is pressed, a key pressing signal is transmitted to the buzzer sound generator. The buzzer sound generator outputs a buzzer sound and transmits it to the volume control device. The volume control device outputs the volume 1 according to the ratio of 1: 5 set in advance by the volume selection device and the volume of the volume 1 set in advance by the volume selection device. When an abnormal pattern A occurs in the power conversion device, the abnormality detection device detects an abnormality, outputs an error signal A, and transmits it to the alarm sound generation device. The alarm sound generator outputs an alarm sound A and transmits it to the volume control device. The volume control device outputs the volume 5 according to the ratio of 1: 5 preset by the volume selection device. Similarly, when the abnormal pattern B occurs, the sound volume 5 is output.

いずれの実施形態の場合においても、音量選択装置では電力変換装置を操作する環境に応じて、不快の無い音量指令、比率を選択して設定することができる。   In any of the embodiments, the sound volume selection device can select and set a sound volume command and a ratio that are not uncomfortable according to the environment in which the power conversion device is operated.
