装置（ＣＰＵ）１９に入力される。FIG. 2 shows a side sectional view of the monitoring unit 8. The monitoring unit 8 has a monitoring window 14 on the front side of a case 13 formed in a box shape.
A pyroelectric element 15, for example, is provided in the inner part of the monitoring window 14 as a detection element that detects the radiant energy of an intruder when an intruder exists within a predetermined area. The signal from this element 15 is input to a processing unit (CPU) 19 provided inside the monitoring unit 8.

開始タイミングを得ることができる。Further, at the bottom of the monitoring unit 8, a display unit 2 is provided with a display unit 20 that displays the operating status of the monitoring unit 8.
0 is composed of LEDs, etc., and in the event of a failure such as when the monitoring unit 8 is unable to detect an intruder, as will be described later,
The failure is indicated externally by blinking, etc. A reed switch 21 is provided inside the monitoring unit 8, and this reed switch 21 is turned on when the monitoring unit 8 is mounted on the mounting plate 11, and the CPU 19 can detect the mounting state based on this mounting signal. , the start timing of the monitoring operation, which will be described later, can be obtained.
第３図に示すのは、監視ユニット８内部に設けられる前

。FIG. 3 shows a block diagram of the configuration of the above-mentioned electrical circuit provided inside the monitoring unit 8.
次に上述の構成による監視動作について第４図のタイミ
ングチャートを用いて説明する。Next, the monitoring operation with the above-described configuration will be explained using the timing chart of FIG. 4.
まず、第１図に示すように監視ユニット８は、取付は板
ＩＯに対し点線で示す如く取付けられている。この時、
監視ユニット８は非警戒状態となっている。First, as shown in FIG. 1, the monitoring unit 8 is attached to the plate IO as shown by the dotted line. At this time,
The monitoring unit 8 is in a non-alert state.
次に、金庫１の！！３が閉じられた後、第５図に示す如
く監視ユニット８を手で持ち、取付は板ｌＯから外して
装着板１１に取付ける。従って、この時、監視ユニット
８の焦電素子１５は、当然操作ｇが所定の警戒領域内に
存在するため、操作者の手から発生する人体エネルギー
を検出している。この人体検出信号Ｓ２は、ＣＰｔＪ１
９を介して図示しない記憶部にこの旨のデータが時系列
に一定時間記憶される。Next, safe 1! ! 3 is closed, the monitoring unit 8 is held by hand as shown in FIG. Therefore, at this time, the pyroelectric element 15 of the monitoring unit 8 is detecting the human body energy generated from the operator's hand, since the operation g is naturally within the predetermined warning area. This human body detection signal S2 is CPtJ1
9, data to this effect is stored in a storage unit (not shown) in chronological order for a certain period of time.
そして、監視ユニット８が装着板１１に装着されること
によりマグネット１２の磁気力でリードスイッチ２１が
メークされ、時間１１で装着信号Ｓｌが出力される。When the monitoring unit 8 is mounted on the mounting plate 11, the reed switch 21 is made by the magnetic force of the magnet 12, and the mounting signal Sl is output at time 11.
ここでＣＰＵ ｌ ９は、瞬時に前記装着信号Ｓｌの発
生タイミングから過去一定期間遡り人体検出信号Ｓ２が
発生しているか否かを判断する。Here, the CPU 19 instantaneously determines whether or not the human body detection signal S2 has been generated for a certain period of time in the past from the generation timing of the mounting signal Sl.
つまり、監視ユニット８を装着板１１に装着するために
は、必ず手による装着動作が必要であることから装着以
前一定期間Ｔ中に、焦電素子１５は必ず人体エネルギー
を検出していることになる。In other words, in order to attach the monitoring unit 8 to the attachment plate 11, manual attachment is always required, so the pyroelectric element 15 always detects human body energy during a certain period T before attachment. Become.
これを検出している場合ＣＰＵ Ｌ ９は、焦電素子１
５が正常に動作していることを判断し、装着信号出力後
警戒状態となり、金庫ｌに接近する侵入者の監視を行な
うことになる。When this is detected, CPU L 9 detects pyroelectric element 1.
After determining that the safe 5 is operating normally and outputting a mounting signal, the safe 1 enters a warning state and monitors for intruders approaching the safe 1.
一方、ＣＰＵ１９は装着信号Ｓ１を受信したとき監視ユ

身の機器異常状態である旨を知らせる。On the other hand, when the CPU 19 receives the attachment signal S1, if the pyroelectric element 15 does not detect human body energy during the period T before the monitoring unit 8 is attached to the attachment plate 11, the pyroelectric element 15 has failed. It is assumed that there is a problem and an abnormality signal S3 is output. In response to the abnormality signal S3, the LED of the display section 20 switches to a blinking operation to notify the operator that the monitoring sensor 5 itself is in an abnormal state.
上記動作により焦電素子１５の故障判別を行なうことが

。Through the above operation, it is possible to determine the failure of the pyroelectric element 15. In addition, if there is an intruder during the alert state, the monitoring sensor 5 detects the intruder, and the ff13 of the safe l
When the lead wire 7 is opened, a signal is sent to the i-nuclear device indicating that there is an abnormality in the penetration.
