の範囲内に修復させることを目的とする。This invention was made to solve the problems mentioned above.Automatic VC/l! iI Measures the ambient temperature and if the value of 7 falls outside the range of the measurement used, it will detect an abnormality of 7 and issue alarms and error information, as well as connect directly to the air conditioner and operate the temperature control device automatically. The purpose is to restore the temperature within the operating ambient temperature range.
この発明に係る温度検知装置は、温度センサを内蔵して
自動的に異常温度を検知して警報を出したり、外部に設
けたエアコンと連動させて自動的に使用周囲温度の範囲
内に修復するようにしたものでおる。The temperature detection device according to the present invention has a built-in temperature sensor that automatically detects abnormal temperature and issues an alarm, or automatically restores the temperature within the operating ambient temperature range by linking with an external air conditioner. This is what I did.
この発明における温度検知装置は、温度センサにより検
知したアナログ値がCPUに入方され、異常情報を外部
に出力する。In the temperature detection device according to the present invention, the analog value detected by the temperature sensor is input to the CPU, and abnormality information is outputted to the outside.
以下、この発明の一笑施例金図について説明する。第1

7ンの内容を読み出し入出力制御メモリ(9)を経由し
て、出力ユニり1−C10へ異常信号を出す。The central processing unit (6) uses the passed value as W1, which is the operating temperature.
If an error occurs outside the range, error information is stored in the abnormality detection memory (7). Next, the user program (8) is stored in the abnormality detection memory (
The contents of unit 7 are read out and an abnormal signal is sent to output unit 1-C10 via input/output control memory (9).
