Description of the Related Art In recent years, electronic equipment is usually equipped with a commercial AC power source as a power source, rectifies an AC voltage and converts it into a DC voltage, and uses it as a circuit power source. A power supply has emerged which is automatically supplied with electric power for circuit power supply from a battery unit at the time of power failure of an AC power supply and can charge the battery unit as necessary. There is an uninterruptible power supply device of this type that is capable of monitoring the connection state and charging status of the battery unit. One of them is the uninterruptible power supply device of Japanese Patent Application No. 5-226832, which was previously created by the inventors of the present application and already filed separately. In the previous application, while having an A / D converter,
When one of the voltage dividing resistors is connected to a plurality of battery parts, the combined resistance becomes smaller according to the number of the battery parts, and it is derived from the A / D converter that the divided voltage decreases. The number of connected battery parts and the presence / absence of connection are detected.

った。In the above-mentioned conventional monitoring of the connection state of the battery unit, the voltage of the battery for monitoring is set to A / D.
In order to obtain the voltage for conversion, it is applied to the voltage dividing resistor and relatively current flows, and because it uses the battery voltage for backup, it operates even when the AC power supply is "OFF", that is, during a power failure. Therefore, there is a problem that the backup battery is largely consumed and various information cannot be stored for a long time.

In the “N” state, a monitoring means is provided for monitoring the connection state of the battery section based on the signal from the first signal output means, and in the “OFF” state based on the signal from the second signal output means. There is.

At the time of “N”, the circuit section operates with the voltage from the AC power supply,
In addition, since the voltage corresponding to the number of battery parts is output from the first signal output means in the determination of the “ON” state, the monitoring means can finely discriminate this voltage value and know the number of connections. On the other hand, when the AC power supply is turned off, "OF
By the "F" determination, the second signal output means outputs a signal indicating whether or not the battery unit is connected, for example, one of "high" and "low" signals, so that the monitoring means outputs "high" and "low". By detecting the presence or absence of connection,
I can remember more. In this case, since it is only necessary to discriminate between “high” and “low”, for example, it is not necessary to pass a large current through the voltage dividing resistor, resulting in low power consumption.

The resistance value of the resistor R 3 is set to be large (100 kΩ to 1 MΩ) with respect to (about 10 kΩ), and the resistors R 1 and R
The voltage V 1 is divided by 2 and the voltage V 2 is divided by the resistors R 3 and R 2 . When the power supply is "ON", that is, when the control unit 20 is supplied with the AC power, the voltage V 1 is applied from the power supply unit 28, and in this case, the divided voltage of the resistors R 1 and R 2 is applied.

It is taken in 6 and the voltage is converted into a digital value by the built-in A / D converter. In this case, the larger the number of battery units connected to the control unit 20, the larger the number of resistors R 1 connected in parallel, the smaller the combined resistance value between the terminals P 1 and P 4, and the smaller the voltage at the terminal P 1. Become. Therefore, the number of connected battery units can be known from the magnitude of the value obtained by A / D converting the voltage of the terminal P 1 .

In the "ON" state by the "FF" discriminating means, the connection state of the battery part is monitored based on the signal of the first signal output means, and in the "OFF" state, based on the signal of the second signal output means. An uninterruptible power supply comprising a monitoring means for
ＦＦ」から「ＯＮ」への切替時に、第１の信号出力手段
の出力、第２の信号出力手段の出力のうち、先に監視し
ていた信号出力を、後の信号出力に換算して、移動平均
した後の出力信号で、バッテリ部の接続状態を監視する
ようにした請求項１記載の無停電電源装置。2. From "ON" to "OFF" or "O"
At the time of switching from "FF" to "ON", of the outputs of the first signal output means and the second signal output means, the signal output monitored earlier is converted into the signal output after, The uninterruptible power supply according to claim 1, wherein the connection state of the battery unit is monitored by the output signal after the moving average.
