Abstract
PURPOSE: Informations sent from several safety devices are introduced into a computer and displayed on the screen so as to be monitored effectively.
CONSTITUTION: A control device 101 has various switches of safety devices. Signals 105 sent from the control device are input to an interface circuit 103. These signals 105 are introduced by turns into a microcomputer by means of the time sharing by the microcomputer 107. When a contact of a safety device is closed, this is memoried in the computer 107. A buzzer 113 is rung and the time prerated, the number or installation location of the escalator in trouble, the name of the safety device operated, the contents processed when the safety device worked are all shown on the CRT display 111.
