As shown in FIG. 8, the walking customer alarm method during the escalator operation according to the present invention outputs a voice from a voice device through a speaker at a set time interval, . That is, when the initial power is turned on, the announcement is normally transmitted through the speaker in the audio device at the set value (time) interval.

The control unit 130 of the program unit 100 or the control unit 640 of the PLC module 600 generates an event of whether the movement of the customer is detected during operation of the escalator S110, It is determined whether the moving speed is faster than the moving speed (S120). At this time, as described above, it is also possible to detect the movement speed of the step through the detection sensor and the movement speed due to the deviation detected by the detection sensor, or in other ways, a timer for checking the walking time of the customer through the program Since the step movement speed is set, the movement speed of the customer is determined according to the detection results from the first to n < th > n sensors 210, 220 and 230, It is possible to detect whether the movement of the customer detected by the plurality of detection sensors 210, 220 and 230 is a stepwise movement or an actual customer movement according to a set timer. If it is determined by the timer that the moving time of the customer is faster than the set time (for example, 1 second or more) according to the timer setting, the control unit 140 turns on the warning light 300, (S130).

Next, the control unit 140 detects the speed at which the customer's moving speed moves according to the sensed result of the first to n-th sensing sensors 210, 220 and 230 and the set step moving speed at step S140. The walking speed and the running speed can be set according to the field test, so there is no particular limitation.

As a result of the detection, the controller 140 sends a guidance voice through the guidance voice apparatus according to whether the customer is running or a walking state (S150). If it is detected to be running, it broadcasts an announcement message such as 'Do not run', and if it is detected that it is walking, a direct announcement message such as 'Do not walk' is transmitted. If there is a customer who is running or walking like this, if a warning light, a buzzer, and a guidance voice are sent out, the customer will be stopped from running or walking while being aware of the surroundings, It is possible to maximize the safety of customers such as adults and children.

This operation is performed until power-off to the escalator (S160).
