Abstract

<P>PROBLEM TO BE SOLVED: To provide an effective catnap alarm for preventing the shift from an awakening status to a non-REM sleep. <P>SOLUTION: This catnap alarm is configured to determine that an operator is caught asleep when a click is stopped although the operator makes up his or her mind to continuously and repeatedly click a switch in an awakening status. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は重要作業の時などに、作業者の居眠りを防止するための警報装置である。The present invention is an alarm device for preventing a worker from falling asleep during important work.

自動車運転などの重要作業中に、作業者の居眠りによる重大事故が頻発している。その居眠り防止のための発明もいろいろと出願されてはいるが、いづれも現場への実施にはいま一つの感があり、なかなか普及には到っていないようである。
特許公開平０８−２９０７２６特許公開平０７−２２３４５６ Serious accidents due to workers falling asleep frequently occur during important work such as driving a car. Although various inventions for preventing the snooze have been filed, there is still a feeling of implementation in the field, and it seems that it has not yet reached widespread use.

居眠り状態の検出の問題について。センサ−の装着や取り付けに際し、取り付け、調整に精密さを必要としたり、使用者が煩しく感じたりして現場においては敬遠されがちなことや装置が複雑であったりし一般人の理解が得にくい事などが普及しにくい要因のようである。 About the problem of detecting dozing. When installing and installing the sensor, precision is required for installation and adjustment, and the user feels troublesome, and the device is often overlooked and the device is complicated, making it difficult for the general public to understand. This seems to be the reason why things are difficult to spread.

人は疲労、疾病、寝不足その他いろいろな理由で意識が薄れ所謂覚醒状態からノンレム睡眠の居眠り状態に移行し、姿勢は保持できるに拘らず意識は朦朧となり、やらねばならぬ仕事なども忘却される。食事後の適度な温度環境下では刺激の少ない単純作業での長時間連続労働ともなれば、ノンレム睡眠に引き込まれ易くなるのはむしろ当然なことかと考えられる。 People lose their consciousness for various reasons such as fatigue, illness, lack of sleep and so on, so-called wakefulness shifts to non-REM sleep dozing state, while their posture can be maintained, their consciousness becomes drunken, and work that must be done is forgotten . Under normal temperature conditions after meals, it seems natural that it becomes easy to be drawn into non-REM sleep if it becomes long-time continuous work with simple work with little irritation.

作業者自身が覚醒時にクリック・スイッチを繰り返しクリックするとの決意を固めたに拘わらずクリック操作が途絶えてしまったことをもって、装置はこれを居眠りと判定し警報を発するものである。
鳥井鎮夫編「睡眠の科学」朝倉書店井上昌次郎著「脳と睡眠」共立出版１９８９年 When the operator himself decides to repeatedly click the click switch when he / she wakes up, the device determines that this is a doze and issues an alarm when the click operation stops.

作業者の繰り返しクリックするとの決意の実行が、精神への継続的な刺激となり、覚醒状態からノンレム睡眠への移行を妨げる方向に効果的である事を期待できる。 It can be expected that the execution of the worker's determination to click repeatedly is a continuous stimulation to the mind and is effective in preventing the transition from wakefulness to non-REM sleep.

図１は本発明の警報装置本体とクリック・スイッチおよびブザ−・スイッチなどの関係と形態を示す斜視図である。本装置の取り扱い方を図１について説明する。まず、初めにブザ−・スイッチ３はオフ状態にあるものとする。その頃、作業者が眠気を感じクリック・スイッチ１をクリックした後、ブザ−・スイッチ３をオンに、それ以後は内蔵の電子タイマ−の保持時間ｔ秒以内の間隔でクリック・スイッチ１のクリック操作を繰り返せば、ブザ−５は警報音を発しないが、クリックが途絶えた場合、警報音を発することとなる。 FIG. 1 is a perspective view showing the relationship and form of an alarm device main body, a click switch, a buzzer switch, etc. of the present invention. A method of handling this apparatus will be described with reference to FIG. First, it is assumed that the buzzer switch 3 is in the off state. At that time, after the operator felt sleepy and clicked the click switch 1, the buzzer switch 3 was turned on, and after that, the click operation of the click switch 1 was performed at intervals within the holding time t seconds of the built-in electronic timer. If buzzer 5 is repeated, the buzzer 5 does not emit an alarm sound, but when the click is stopped, an alarm sound is generated.

It can be clicked lightly with the left fingertip, and has little trouble with driving operations.

図３は本発明の動作を表すタイミング・チャ−トである。図３のタイミング・チャ−トについて説明する。Ａラインはクリック・スイッチ１によるパルス波型。Ｂラインは内蔵する電子タイマ−の出力波型。Ｃラインはブザ−５への入力波型。また各波型の斜線部分は能動域を表す。クリック・スイッチ１をクリックする毎に、Ａラインのパルスｐは立ち上がる。このパルスｐの立ち上がりを期にＢラインの電子タイマ−は立ち上がりｔ秒経過後に立ち下がる。しかしこのタイマ−は常に新たなパルスｐが立ち上がる毎に更新される構造であり、最後のパルスｐの立ち上がり後ｔ秒間は保持されるが、保持時間が終わり電子タイマ−が落ちると同時にＣラインのブザ−５は立ち上がり、警報音を発することになる。 FIG. 3 is a timing chart representing the operation of the present invention. The timing chart of FIG. 3 will be described. A line is a pulse wave type by click switch 1. B line is the output wave type of the built-in electronic timer. C line is the input wave type to buzzer-5. The hatched portion of each wave type represents the active area. Each time the click switch 1 is clicked, the pulse p of the A line rises. With the rise of the pulse p, the B-line electronic timer falls after elapse of t seconds. However, this timer is always updated every time a new pulse p rises, and is held for t seconds after the last rise of the pulse p, but at the same time as the electronic timer falls, The buzzer 5 rises and emits an alarm sound.

Claims

In the detection method of the worker's dozing state, the switch that can be operated according to the worker's own will be repeatedly clicked at intervals of several seconds to confirm the worker's arousal state. A drowsiness alarm device that makes a judgment and issues an alarm.

Also included are those that can exhibit the same effect as a switch that operates according to the will of the worker of claim 1. For example, it consists of a combination of a microphone, its amplifier and a relay circuit, etc., which can be operated by utterance of a command or the like.
