A voltage is generated and supplied to the operation control device 6.

As a result, as shown in the flow chart of FIG. 2, the operation control device 6 refers to the history data stored in the power supply detection device 4, and the judgment flag "P"
It is checked whether the value of SF "is" 0 ", and if the value of the determination flag" PSF "is" 1 "(step S
T1), normal startup, or loss of microcomputer power supply voltage,
It is determined that the microcomputer has started up due to a temporary stop of the microcomputer, such as self-reset due to a microcomputer abnormality, and the procedure according to the control contents up to the previous time, for example, the previous stop is performed in the normal stop procedure. If the stop
The initialization program is referred to, each part of the escalator mechanism is initialized, and the operation of the escalator mechanism is started.

If there is no information indicating a normal stop in the control contents up to the previous time, the operation control device 6 causes a temporary stop of the microcomputer such as loss of the microcomputer power supply voltage and self-reset due to microcomputer abnormality. It is determined that the cause is the rise of the microcomputer, and the control of the escalator mechanism 2 is continued with the control contents up to the previous time (step ST4).

After that, as shown in the flow chart of FIG. 3, any abnormality occurs in any of the microcomputer power supply 5, the system power supply 3, the power detection device 4, etc., which constitute the system, for example, the system power supply 3. , The system power supply 3 does not output the system power supply voltage,
When the escalator mechanism 2 is stopped (step ST1

<< Sixth Embodiment >> FIG. 10 is a block diagram showing a sixth embodiment of the escalator control system according to the present invention. In this figure, the same parts as those in FIG. 1 are designated by the same reference numerals.

Escalator control system 1 shown in this figure

That is, the sensor 14 is provided.

Then, as shown in the flow chart of FIG. 11, when the system power supply voltage is no longer output from the system power supply device 3, the power supply detection device 4 detects this and the determination flag "PS" included in the history data is detected.
The value of “F” is set to “0”, and thereafter, the microcomputer starts up while the escalator mechanism 2 is kept in the automatic driving standby state by the automatic driving control device 13 until the passenger detection signal is output from each photoelectric sensor 14. When the determination flag “P
It is checked whether the value of "SF" is "0", and if the value of the determination flag "PSF" is "0" (step ST41), the escalator mechanism 2 is shifted to the manual operation and each photoelectric sensor 14 is operated. Even if the passenger detection signal is output from the escalator mechanism 2, after the automatic operation of the escalator mechanism 2 is prohibited (step ST42), the value of the determination flag "PSF" is set to "1".
