【発明が解決しようとする課題】しかし、上記の技術は以下のごとき欠点を有していた。 [SUMMARY OF THE INVENTION However, the above technologies had the following such drawbacks. 量子化誤差を減らすために、所定の期間内でのサンプリングを多くすると、高速広帯域オペアンプ及び、高速動作可能なサンプルホールド回路及びAD変換器が必要になる。 To reduce the quantization error, when increasing the sampling within a predetermined time period, high-speed broadband operational amplifiers and high-speed operation can sample and hold circuit and an AD converter is required. 所定の期間内でサンプリングされた、多くのデータを収集し一括処理するため、データを保管するためのデータ蓄積専用RAMが必要である。 Sampled within a predetermined time period, for batch processing to collect a lot of data, it is necessary data storage dedicated RAM for storing data. 通常の高速サンプリングでは、電流出力回路と電圧出力回路の各々の系統に高速広帯域オペアンプ、サンプルホールド回路及び高速AD変換器を必要とした。 In a typical high-speed sampling, and high-speed broadband operational amplifier in each of the systems of the current output circuit and the voltage output circuit, requiring sample-and-hold circuits and high-speed AD converter. また、 Also,

【実施例】図1は本発明のバッテリ試験装置の実施例であって、1はバッテリ電流検出回路、13,14はオペアンプ、15はアナログマルチプレクサ、16は低速のサンプルホールド回路、17はAD変換器、7はバッテリ電圧検出回路、12はマイクロプロセッサである。 PREFERRED EMBODIMENTS FIG. 1 a embodiment of a battery testing device of the present invention, 1 is the battery current detection circuit, 13 and 14 operational amplifier, 15 an analog multiplexer, a low speed of the sample hold circuit 16, 17 AD converter vessel, 7 is the battery voltage detection circuit, 12 is a microprocessor.

【0014】次にその動作を説明する。 [0014] Next, the operation thereof will be described. 所定の期間内で、バッテリの充放電電流I BATTは、バッテリ電流検出回路1においてシャント抵抗若しくはホール素子等の検出方法で電流電圧変換され、オペアンプ13に於て、後段の回路が処理できる範囲の適当な電圧値まで増幅される。 Within a predetermined time period, the charge and discharge current I BATT of the battery, in the battery current detection circuit 1 is a current-voltage conversion by the detection method such as a shunt resistor or a Hall element, At a operational amplifier 13, the range of the subsequent circuit can handle It is amplified to an appropriate voltage value.

【0015】一方、バッテリの端子電圧V BATTは、所定の期間内で、バッテリ電圧検出回路7において直接若しくは抵抗分圧回路等の検出方法でオペアンプ14に送られ、バッテリの充放電電流の検出方法と同様に、後段の回路が処理できる範囲の適当な電圧値まで増幅される。 Meanwhile, the terminal voltage V BATT of the battery is within a predetermined time period, are sent to an operational amplifier 14 in the detection methods, such as direct or resistive divider in the battery voltage detection circuit 7, a detection method of a battery charge and discharge current Similarly, subsequent circuit is amplified to a suitable voltage range that can be processed with.

【0016】次に、バッテリ電流の増幅された電圧値とバッテリ電圧の増幅された電圧値は、一組のアナログマルチプレクサ15に入力され、該バッテリ電流とバッテリ電圧が低速のサンプルホールド回路16にて、交互にサンプリングされ、かつホールドされる。 Next, the amplified voltage value of the amplified voltage value and the battery voltage of the battery current is inputted to a pair of analog multiplexer 15, the battery current and the battery voltage is at a low speed sample and hold circuit 16 , it is sampled alternately, and is held. ホールドされたデータは、AD変換器17によりディジタル変換され、従来と同様マイクロプロセッサ12の周辺として位置づけられたRAM(図示せず)に逐次保管又は加算され、マイクロプロセッサ12を介して処理される。 The held data is digitally converted by the AD converter 17, are sequentially stored or added to conventional RAM which is positioned as near the same microprocessor 12 (not shown), it is processed through the microprocessor 12.

【0017】この間は例えば試験用バッテリの充放電電流の上昇又は降下時間の100μsを除いて、400μ [0017] During this time, except a 100μs rise or fall times of the charge and discharge current of the battery for example, the test, 400 [mu]
sの時間内で28データの収集で、1データ当たり検出から保管まで14μsと低速である。 In the time in 28 data collection s, which is 14μs and low speed to save the detected per data. また、サンプリングデータ数が少ないため、収集したデータのためのデータ蓄積専用RAMは必要とせず、サンプルホールド回路16はコンデンサと抵抗からなる積分回路により低速に動作するから、その効果として高周波のノイズに対して頑強になる。 Further, since the sampling number of data is small, data storage dedicated RAM for data collected does not require, because the sample and hold circuit 16 operates in a low speed by the integration circuit composed of a capacitor and a resistor, the high-frequency noise as the effect become robust for.

【0018】又、従来回路では高速サンプリングを行っており、サンプリングを高速化する為には、システムの大型化をまねいた。 [0018] In addition, in the conventional circuit has made a high-speed sampling, in order to speed up the sampling, led an increase in the size of the system. しかし、本発明の回路はサンプルホールド回路の積分回路により、サンプリングデータを平均化する事が出来るため、サンプリングの低速化が可能であるので、電流検出信号と電圧検出信号は、アナログマルチプレクサにより交互に切替え処理が可能なので、 However, the integration circuit of the circuit is a sample-hold circuit of the present invention, since it is possible to average the sampled data, since it is possible to slow the sampling, the current detection signal and the voltage detection signal, alternately by an analog multiplexer since the switching process is possible,
1系統のサンプルホールド回路及びAD変換器で構成することができる。 It can be configured by the sample-and-hold circuit and an AD converter of one system.

【0019】尚、検出からデータ処理までの一連の動作は、市販のシングルチップマイコン18に置き換えるとシステムが簡素化される。 [0019] Incidentally, the series of operations from the detection to the data processing, the system replacing the commercial single-chip microcomputer 18 is simplified. しかしこれらのシングルチップマイコンは最大10ビットが一般的である。 However, these single-chip microcomputer maximum 10 bits are common. 従って、 Therefore,
測定精度を上げるためには図2のようにマイクロプロセッサ12を別チップとし、他の部分をAD変換チップ1 In order to increase the measurement accuracy as a separate chip microprocessor 12 as shown in FIG. 2, AD converter chip 1 and the other part

【発明の効果】本発明によれば、汎用のオペアンプ、低速のサンプルホールド回路及びAD変換器を使用し、さらにデータ蓄積専用RAMを必要としない為、バッテリ試験装置は低価格になり、システムが小型化される。 According to the present invention, a general-purpose operational amplifier, using a slow sample hold circuit and AD converter, since that does not require further data storage dedicated RAM, battery testing device comprises a low cost, the system It is miniaturization.
又、サンプルホールド回路はコンデンサと抵抗の積分回路により低速動作するから、高周波ノイズに対して頑強になり、耐ノイズ性が改善されることが期待される。 Moreover, the sample and hold circuit because low speed operation by the integrating circuit of a resistor and a capacitor, it becomes robust against high frequency noise, it is expected that the noise resistance is improved. また、このバッテリ試験装置を電力装置に組み込むことにより、監視強化が図られるため電力装置全体の信頼性を向上させることができる。 Further, by incorporating the battery testing device to the power device, it is possible to improve the reliability of the entire power system for intensified surveillance is achieved.
