本発明は、無人運転を行っている電子計算機システムが
、停電によシ停止した場合の復電によシ自動的に立上げ
るｔ源投入方式に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a system for automatically starting up a power supply when an unmanned computer system is stopped due to a power outage. Regarding the method.
特開昭６２−２６５２２号には、停電検出時からの経過
時間全監視し、所定時間が経過するまで復電−時におけ

よる誤動作の発生を防止する技術が示されている。Japanese Patent Laid-Open No. 62-26522 discloses a method for preventing malfunctions caused by instantaneous power outages by monitoring the entire elapsed time from the time a power outage is detected and completely suppressing the output of power-on signals at the time of power restoration until a predetermined period of time has elapsed. A technique to prevent this is shown.
上記従来技術では、電子計算機システムが停止したかど

立上げができない。In the above-mentioned conventional technology, in the case of a momentary power failure, the computer cannot be restarted for a certain period of time, regardless of whether the computer system has stopped or not.
本発明の目的は、上記従来技術の間頭点を解決し、瞬停

自動的に再立上げする事にある。It is an object of the present invention to solve the problems of the above-mentioned prior art, and to solve the problem of computer systems that have stopped due to power outages including instantaneous power outages. ,
It will restart automatically.
上記目的は、電子計算機システムの動作検出手段と停電
検出回路を例えば分電盤と計算機システムの間に追加す
ることで達成できる。The above object can be achieved by adding an operation detection means and a power failure detection circuit of the computer system, for example, between the distribution board and the computer system.

に備える。A power-on command to the computer system is issued upon detecting the operating status of the computer system at the same time as the power failure is detected. As a result, if the slave computer system is stopped due to a reason other than a power outage, a power-on command is not issued because the power outage is not detected (case 1). Further, even if a power outage is detected, a power-on command is not issued even if the computer system does not stop (case 2). If such control is implemented, there is a possibility that the detection result of a computer system stoppage will be held unnecessarily in the case 1 above, and the detection result of a sunny power outage in the case 2 may be held unnecessarily. Therefore, this detection mechanism resets after a certain period of time and prepares for future power outages.

３１０４にて瞬停を含めた停電全検出する。An embodiment of the present invention will be described below with reference to FIG. 1. An electronic computer system 101 operates on a commercial power source 102. If the commercial power supply 102 has a power outage, the power outage detection port w
At 3104, all power outages including instantaneous power outages are detected.
瞬停を含めた停電検出回路１０４そのものについては従

源投入命令１０７を発行する。The electronic computer system 101 indicates the operating status using a stop signal 10.
6 to the power-on device 106. The power-on device 103 issues a power-on command 107 to the computer system 101 when both the power failure detection signal 105 and the stop signal 106 are detected.

上げする事ができる。The power supply device U103 resets the power failure detection circuit 104 in response to the reset of the stop signal 106. Further, if the rt child computer system 101 does not stop due to an instantaneous power failure, the stop signal 106 is not detected, so the power-on command 107
is not published. In this case, the power outage detection signal 105 is
Reset after a certain period of time. Even if the computer system 101 is stopped due to reasons other than a power outage, the power-on command 107 is not issued because the power outage detection signal 105 is not set, and the computer system 101 is in a stopped state. In this way, only the stoppage of the computer system 101 due to a power outage can be detected, and the computer system 101 can be automatically restarted after the power is restored.
