The control device 12 and the earthquake early warning analysis device 13 are connected to each other. The earthquake early warning received by the earthquake early warning receiving device 14 is sent to the escalator control panel 9, the earthquake control operation control device 12 and the emergency earthquake early warning analyzing device 13, respectively, and the analysis information analyzed by the emergency earthquake early warning analyzing device 13 is provided. Is sent to the seismic control operation control device 12 and further sent to the escalator control panel 9 to perform seismic control operation of the escalator.

Next, the operation of the escalator earthquake control operation device will be described based on the flowcharts of FIGS. 2 and 3.
First, in step S1, it is determined whether or not the earthquake early warning receiving device 14 has received an emergency earthquake early warning. If not received, the process ends. When receiving the earthquake early warning, the earthquake early warning receiving device 14 transmits a signal to the escalator control panel 9 and receives the earthquake early warning to the escalator user and surrounding facility users by the equipment installed in the escalator or the like. This is notified (step S2). As the notification means, for example, as shown in step S2, the warning lamp 3 is turned on, the received content of the emergency earthquake bulletin is announced to the surroundings by the speaker 1, and the received content of the emergency earthquake bulletin is displayed on the display 2. Next, the escalator control panel 9 confirms the presence / absence of passengers with the equipment installed on the escalator (step S3). As this passenger presence / absence confirmation means, for example, as shown in step S3, a camera image is analyzed by the image analysis device 6, and the presence / absence of a passenger is confirmed. The passenger confirmation sensor 7 confirms the presence / absence of a passenger. 8 is used to confirm the presence or absence of passengers from the last person's boarding time. The escalator control panel 9 confirms the passenger boarding situation and transmits a passenger situation signal to the seismic control operation control device 12. The seismic control operation control device 12 transmits the following four patterns of operation requests to the escalator control panel 9 according to the passenger boarding situation on the escalator at the time of receiving the earthquake early warning.

I. When there is no passenger on the escalator When it is determined in step S4 that there is no passenger on the escalator, the escalator control panel 9 notifies the surroundings of the stop of the escalator due to the reception of the earthquake early warning (step S5). As the notification means, for example, as shown in step S5, the speaker 1 announces that the escalator is stopped by receiving the earthquake early warning, and the display 2 displays that the escalator is stopped by receiving the earthquake early warning. Further, the escalator control panel 9 stops the operation of the escalator after the entrance prevention fence 4 at the entrance / exit is closed in order to prevent new passengers and prevent secondary disasters caused by falling. The escalator control panel 9 notifies the communication device 10 of “Escalator operation stop due to reception of earthquake early warning”, and the communication device 10 notifies the information center 11 of “Escalator operation stop due to reception of emergency earthquake warning”.

II-1. When there is a passenger on the escalator and driving at normal speed If there is a passenger on the escalator in step S4, the earthquake early warning analysis device 13 calculates the estimated time of arrival of the earthquake and also uses the passenger status signal from the escalator control panel 9 as a source. The time for the passenger on the escalator to get off is calculated (step S6). Next, in step S7, the seismic control operation control device 12 compares the estimated passenger arrival time with the predicted earthquake arrival time calculated by the emergency earthquake early warning analysis device 13, and the passengers from the earthquake arrival even in normal speed operation. When it is determined that the vehicle is getting off earlier, the escalator control panel 9 is requested to perform seismic control operation by normal speed operation (steps S8 to S10). Further, the escalator control panel 9 calls the suspending of the escalator to the surroundings. As the contents, the speaker 1 announces that the escalator will be stopped soon after receiving the earthquake early warning, and the display 2 displays that the escalator will be stopped soon after receiving the earthquake early warning. Further, the escalator control panel 9 closes the entrance entry prevention fence 4 to prevent new passengers, and the escalator control panel 9 operates the escalator at a normal speed (step S8). Next, the escalator control panel 9 transmits a passenger status signal to the seismic control operation control device 12 and constantly confirms it. After the seismic control operation control device 12 confirms the passenger getting off (step S9), the escalator control panel 9 The escalator stop request is transmitted, and the escalator control panel 9 notifies the escalator stop to the surroundings (step S10). As the notification means, for example, as shown in step S10, the speaker 1 announces that the escalator is stopped by receiving the earthquake early warning, and the display 2 displays that the escalator is stopped by receiving the earthquake early warning. Moreover, the escalator control panel 9 stops the operation of the escalator after closing the entrance prevention fence 4 at the exit in order to prevent a secondary disaster caused by falling. The escalator control panel 9 notifies the communication device 10 of “Escalator operation stop due to reception of earthquake early warning”, and the communication device 10 notifies the information center 11 of “Escalator operation stop due to reception of earthquake early warning”.

II-2. When there is a passenger on the escalator and speeding up the operation In step S7, the earthquake control operation control device 12 compares the estimated passenger arrival time with the predicted earthquake arrival time calculated by the earthquake early warning analysis device 13, and operates at normal speed. If it is determined that the arrival of the earthquake is earlier than the passenger's getting off, comparison of the passenger's getting-off time calculated on the assumption that the speed of the escalator is increased and the estimated time of arrival of the earthquake calculated by the earthquake early warning analysis device 13 Is performed (step S11). When the earthquake control operation control device 12 determines that the passenger is getting off earlier than the arrival of the earthquake, the earthquake control operation control device 12 requests the escalator control panel 9 to perform the earthquake control operation by the speed-up operation (steps S12 to S14). Further, the escalator control panel 9 calls the suspending of the escalator to the surroundings. Although not shown in the figure, the speaker 1 announces that the escalator will stop soon after receiving the earthquake early warning, and the display 2 displays that the escalator will stop soon after receiving the earthquake early warning. Further, the escalator control panel 9 closes the entrance entry prevention fence 4 to prevent new passengers (step S12). The escalator control panel 9 notifies the surroundings that the speed of the escalator is increased in order to complete the dismounting before the arrival of the earthquake. As its contents, the speaker 1 announces that the speed of the escalator is increased, the display 2 displays that the speed of the escalator is increased, and the escalator control panel 9 operates by accelerating the speed of the escalator (step S12). Next, the escalator control panel 9 transmits a passenger status signal to the seismic control operation control device 12 and constantly confirms it, and after the seismic control operation control device 12 confirms the passenger getting off (step S13), the escalator control panel 9 The escalator stop request is transmitted, and the escalator control panel 9 notifies the escalator stop to the surroundings (step S14). As the notification means, for example, as shown in step S14, the speaker 1 announces that the escalator is stopped by receiving the earthquake early warning, and the display 2 displays that the escalator is stopped by receiving the earthquake early warning. Moreover, the escalator control panel 9 stops the operation of the escalator after closing the entrance prevention fence 4 at the exit in order to prevent a secondary disaster caused by falling. The escalator control panel 9 notifies the communication device 10 of “Escalator operation stop due to reception of earthquake early warning”, and the communication device 10 notifies the information center 11 of “Escalator operation stop due to reception of earthquake early warning”.

II-3. If there are passengers on the escalator and the earthquake arrives faster even if the speed is increased, the earthquake control operation control device 12 calculates the passenger's getting-off time and the earthquake early warning analysis assuming that the speed of the escalator is increased in step S11. Even when the estimated earthquake arrival times calculated by the device 13 are compared, if it is determined that the arrival of the earthquake is earlier than the passenger getting off, the escalator control panel 9 is used to reduce the fall of the passenger at the time of the earthquake. A seismic control operation by forced stop is requested (step S15). The escalator control panel 9 notifies the surroundings of the stop of the escalator. As the content, the speaker 1 announces that the escalator is stopped by receiving the earthquake early warning, and the display 2 displays that the escalator is stopped by receiving the earthquake early warning (step S15). The escalator control panel 9 stops the escalator operation (step S15). Although not shown, the escalator control panel 9 should be alerted to prevent falling and falling. As the contents, it is conceivable that the speaker 1 lowers the posture and announces it so as to be grasped by the handrail, and the display 2 displays the posture so as to be lowered and grasped by the handrail (not shown). The escalator control panel 9 notifies the communication device 10 of “Escalator operation stop due to reception of earthquake early warning”, and the communication device 10 notifies the information center 11 of “Escalator operation stop due to reception of earthquake early warning”.
