Description
本考案は一種の無線リモートコントロール多用途電気メーターに係り、特に、電流(A)、電圧(V)、抵抗(Ω)、キャパシタンス(H)、インダクタンス(L)等の信号を測定するのに広く使用され、無線伝送方式で、デンジタル信号を信号受信機に伝送する測定電気メーターに関する。 The present invention relates to a kind of wireless remote control multi-purpose electric meter, especially for measuring signals such as current (A), voltage (V), resistance (Ω), capacitance (H), inductance (L). It relates to a measuring electric meter that is used and transmits a digital signal to a signal receiver in a wireless transmission manner.
一般に周知の電気メーターで電流を測定するには、図1の周知の電源回路の配置に示されるように、総電源箱(10)において複数の分岐電源スイッチが分配され、該総電源箱(10)の総負荷が、複数の分岐負荷(11、12、13、14、15、16)の総和とされる。よく見られる周知の電流測定方式は、総電源箱(10)付近で、電気測定メーター(2)で測定し、この周知の電気測定メーター(2)は、フックメーター或いはクランプメーターと称される。図2も参照されたいが、電気測定メーター(2)は、電流測定クランプリング(21)、測定端子(22)、電流電圧変換器(23)、機能及びシフトセレクタ(24)、ディスプレイ(25)、信号変換器(26)及び選択切り換えボタン(27)で構成され、該電流測定クランプリング(21)で測定した電流は電流電圧変換器(23)を通り更に信号変換器(26)に伝送されて判読可能な信号に変換され、並びにディスプレイ(25)に伝送され、測定された信号が直接数値で表示される。上述の周知の電気測定メーター(2)の原理及び応用方法はこの周知であるため、詳しい説明は省略する。 In order to measure the current with a generally known electric meter, a plurality of branch power switches are distributed in the total power supply box (10) as shown in the known power supply circuit arrangement of FIG. ) Is the sum of a plurality of branch loads (11, 12, 13, 14, 15, 16). A well-known current measurement method is often measured by an electric measurement meter (2) in the vicinity of the total power supply box (10), and this known electric measurement meter (2) is called a hook meter or a clamp meter. See also FIG. 2, but the electrical measurement meter (2) has a current measurement clamp ring (21), a measurement terminal (22), a current-voltage converter (23), a function and shift selector (24), and a display (25). , A signal converter (26) and a selection switching button (27), and the current measured by the current measurement clamp ring (21) is further transmitted to the signal converter (26) through the current-voltage converter (23). Converted into a legible signal and transmitted to the display (25), where the measured signal is directly displayed as a numerical value. Since the principle and application method of the above-mentioned known electric measurement meter (2) are well known, detailed description thereof will be omitted.
周知の測定方式は、先ず各分岐電源スイッチを全部オンし、更に逐一各分岐電源スイッチを切断し、各分岐電源スイッチにかかる電流負荷量がいくらであるかを測定するか、或いはそれと反対の操作モードで、先ず全ての分岐電源スイッチをオフした後に、逐一オンする測定方式で測定される。総電源箱(10)の各分岐電源スイッチの間の距離が遠過ぎる時、少なくとも一人が総電源箱(10)で電気測定メーター(2)を観測し、もう一人が各分岐電源スイッチ部分でスイッチを切り換えなければならず、作業を二人以上で操作しなければならない問題がある。また、二人で操作して測定作業を行なうと、コミュニケーションの連繋において距離が遠過ぎるためにエラーが発生しやすい。或いは非常に高いところを測定する場合、登ったり降りたりして測定するのは相当に面倒である。このほか、逐一各分岐電源スイッチを測定する時、未測定の分岐電源は、他人がいずれかの電器設備をオン或いはオフする時に、不確定の変動状態を形成するため、測定値の誤差を形成する。 A well-known measurement method is to first turn on each branch power switch and then turn off each branch power switch one after another to measure how much current load is applied to each branch power switch, or the opposite operation. In the mode, first, all the branch power switches are turned off, and then measured by a measurement method of turning on one by one. When the distance between each branch power switch of the total power supply box (10) is too far, at least one person observes the electric measurement meter (2) in the total power supply box (10), and the other person switches at each branch power switch part. There is a problem that two or more people must operate the work. In addition, when the measurement work is performed by operating by two people, an error is likely to occur because the distance is too long in communication connection. Or, when measuring a very high place, it is considerably troublesome to measure by climbing up and down. In addition, when measuring each branch power switch one by one, an unmeasured branch power supply creates an indefinite variation state when another person turns on or off any of the electrical equipment, creating a measurement error. To do.
周知の電気測定メーター(2)は、電流(A)或いは電圧(V)を測定する時、測定員が被測定設備の近距離で測定するため、測定作業に極めて高い危険性がある。
周知の製品に存在する欠点を克服し、使用上、更に便利とするため、本考案は提供されるものである。
The known electric measurement meter (2) has a very high risk in measurement work because the measurement person measures the current (A) or the voltage (V) at a short distance of the equipment to be measured.
The present invention is provided to overcome the disadvantages present in the known products and make them more convenient in use.
