Abstract

PURPOSE:To enable an alarm of voltage decrease to be reliably set off by connecting the second battery to both a detector which detects the voltage decrease of the first battery and a displayer on which the result of detection performed by the detector is displayed. CONSTITUTION:This system is provided with a first battery 2a used as a primary power supply driving the whole system, and a second battery 2b. The second battery 2b, a second output displayer 3b and a second voltage comparator 4b constitute a second alarm device 5b which alarms the voltage decrease of the first battery 2a. The second voltage comparator 4b compares the voltage of the first battery 2a with a preset second reference voltage level and delivers a detection signal (S2) to the second output displayer 3b when the voltage of the first battery 2a becomes below the preset second reference voltage level. The second output displayer 3b receives the detection signal (S2) and then sets off an alarm of voltage decrease.

（実施例） 以下９本発明の実施例を図面に基いて説明する。(Example) Hereinafter, nine embodiments of the present invention will be described based on the drawings.

いる。FIG. 1 shows a block diagram of a voltage drop alarm device 1 according to the present invention, and the device 1 is composed of batteries 2a, 2b, output display sections 3a, 3b, and voltage comparators 4a, 4b.

第一の電池２ａは、システム全体を駆動させる主電源と

。The first battery 2a serves as a main power source for driving the entire system, and is a battery 1 that can maintain a constant voltage for a long period of time, such as an alkaline battery or a lithium battery.

よい。Further, the first battery 2a, the first output display section 3a, and the first voltage comparator 4a form a first alarm means 5a that issues an alarm in response to a voltage drop in the second battery 2b. . The first voltage comparator 4a compares the voltage of the second battery 2b with a predetermined first reference voltage, and when the voltage of the second battery 2b becomes equal to or lower than the first reference voltage, the first voltage comparator 4a compares the voltage of the second battery 2b with a predetermined first reference voltage. Output display section 3a
A detection signal S1 is issued to the target. First output display section 3a
In this case, a voltage drop alarm is issued upon receiving the detection signal S1. Note that the first reference voltage is set to be higher than the lowest operating voltage of the second output display section 3b. Further, the voltage value of the first battery 2a may be used as the first reference voltage.

第二の電池２ｂは、第一の電池２ａの電圧チェック用の
電源であり２例えばマンガン系電池が用いられる。The second battery 2b is a power source for checking the voltage of the first battery 2a, and for example, a manganese battery is used.

よい。Further, the second battery 2b, the second output display section 3b, and the second voltage comparator 4b form a second alarm means 5b that issues an alarm in response to a voltage drop in the first battery 2a. . The second voltage comparator 4b compares the voltage of the first battery 2a with a predetermined second reference voltage, and when the voltage of the first battery 2a becomes equal to or lower than the second reference voltage, the second voltage comparator 4b compares the voltage of the first battery 2a with a predetermined second reference voltage. Output display section 3b
A detection signal S2 is emitted to the target. Second output display section 3b
In this case, a voltage drop alarm is issued upon receiving the detection signal S2. Note that the second reference voltage is set to be higher than the minimum operating voltage of the first output display section 3a. Further, the voltage value of the second battery 2b may be used as the second reference voltage.

以上の構成からなる電圧低下警報装置１において、上記
システムが第一の電池２ａによって正常動作していると

されていない。ところが。In the voltage drop alarm device 1 having the above configuration, when the system is operating normally with the first battery 2a, the second alarm means 5b does not output the detection signal S2. However.

第一の電池２ａの電圧が急激に低下すると、直ちに前記
検知信号Ｓ２が出力され、第二の出力表示部３ｂから警
報が発せられる。なお、該警報としては、ＬＥＤ等（図

発振音を出力してもよい。An oscillating sound may also be output.

一方、第二の電池２ｂの電圧が前記第一基準電圧以下に

なお、上記実施例においては、第二の電池２ｂの信頼性
