  FIG. 1 is a schematic configuration diagram showing an escalator system to which a control device and an operation method according to the present invention are applied.

  The escalator system 1 shown in this figure includes a plurality of escalator facilities 2 installed so as to straddle the upper floor side and lower floor side of the building, and a control device 3 that is provided in the maintenance center and controls the operation of each escalator facility 2. The control device 3 controls the operation of each escalator facility 2 and transports passengers.

  Each escalator facility 2 has a drive unit 4, a brake 5, a main drive unit 6, a guide rail 7, a step chain 8, a step chain gear 9 and the like disposed therein, and is operated on the upper floor side and the lower floor side. The panel 10 is provided and has a truss mechanism 11 installed so as to straddle the upper floor side and the lower floor side of the building, a moving handrail 12, a balustrade 13, a plurality of emergency operation indicators 14, and the like. And a handrail mechanism 15 disposed on the upper side. When the power supply voltage is supplied from the commercial power supply on the building side and the operation instruction is output from the control device 3, the drive machine 4 disposed in the truss mechanism 11 is operated to run the step chain 8, Each step 17 is moved, and the moving handrail 12 provided in the handrail mechanism 15 is caused to travel to move the passenger.

  Further, the control device 3 generates the operation content specified by the setting switch (not shown), the instruction content from each operation panel 10, the operation instruction according to the pre-registered operation pattern, etc. The operation of each escalator facility 2 is controlled, and normal operation, earthquake response operation, and the like are performed.

  Next, the operation of the escalator system 1 will be described with reference to the schematic configuration diagram shown in FIGS. 1 and 2, the flowchart shown in FIG. 3, and the schematic diagram shown in FIG. 4.

  As shown in FIG. 2, the four escalator facilities 2 are arranged in a single row connection type that connects between the first floor (1F) to the fifth floor (5F) where the entrance 16 of the building is located, Further, it is assumed that one escalator facility 2 is arranged so as to connect the first floor (1F) and the first basement floor (B1).

  Then, the operation panel 10 provided on each escalator facility 2 or a setting switch or the like is operated, the earthquake response mode is designated, and each escalator facility 2 from the first floor (1F) to the fifth floor (5F) is directed upward. When the operation command to operate the escalator equipment 2 from the first floor to the first basement in the downward direction is input, the control device 3 causes each escalator equipment 2 to perform the up operation corresponding to the operation command content. An instruction or a down operation instruction is generated and supplied to each escalator facility 2.

  As a result, the driving machine 4 arranged in the truss mechanism 11 is operated to start the travel of the step chain 8 and the movement of each step 17 is started, and the moving handrail 12 provided in the handrail mechanism 15 is moved. Traveling starts. And as shown to Fig.4 (a), each escalator equipment 2 between the 1st floor to the 5th floor is going up operation, and the escalator equipment 2 between the 1st floor and the 1st basement floor is going down operation. Then, the transportation of passengers is started.

  During the operation of the escalator facility 2 as described above, when an earthquake occurs and the seismic intensity exceeds a preset seismic intensity, an earthquake occurrence signal is output from an earthquake sensor (not shown). When the earthquake occurrence signal output from the earthquake sensor is input in the control device 3 (step S1), it is determined that it is necessary to evacuate people in the building, and the guide device (illustration is shown) of each escalator facility 2 (Omitted) will output an announcement such as "An earthquake has occurred. All escalators will stop" (step S2). Next, after the drive machines 4 of the escalator facilities 2 are sequentially decelerated, the brake 5 is operated, and the travel of the step chain 8 and the travel of the handrail 12 are stopped (steps S3 and S4). The low speed operation from the normal operation to the stop of the step is maintained for a predetermined time.

  Thereafter, the controller 3 checks whether or not the earthquake response mode is set, and when the earthquake response mode is set (step S5), each escalator facility 2 was operated in a direction away from the doorway 16; Each escalator facility 2 from the 1st floor (1F) to the 5th floor (5F) is changed in setting to descending operation, and the escalator facility 2 from the 1st floor to the 1st floor is changed to setting in ascending operation (step S6). Here, the step moving speed at the time of disaster occurrence is driven at a slower speed than during normal driving. In this case, the low-speed operation from the stop to the re-operation is maintained for a predetermined time.

  Next, the controller 3 changes the escalator on the upside between the 1st floor and the 5th floor to the downside from the guidance device of each escalator facility 2, in order to guide to the evacuation route. Announcement such as “The down escalator to the first basement will be changed to the up side” will be announced. Further, the emergency operation indicator 14 of each escalator facility 2 that is the target of switching the operation direction is turned on, and the user is informed of which escalator facility 2 the operation direction is to be switched (step S7). Thereafter, the control device 3 generates a down operation instruction for each escalator facility 2 from the first floor (1F) to the fifth floor (5F), and an upward operation instruction for the escalator facility 2 from the first floor to the first basement floor. Is generated and supplied to each escalator facility 2.

  Thereby, as shown in FIG.4 (b), while the down operation of each escalator equipment 2 between the 1st floor to the 5th floor is started among each escalator equipment 2, the first floor and the first basement floor Ascending operation of the escalator facility 2 is started, and each user in the building is transported to the doorway 16 (step S8).

  Then, it is determined by a person in the building that the evacuation of each user in the building has been completed, the operation panel 10 provided in each escalator facility 2 or a setting switch is operated, and a reset command is issued. When input (step S9), the control device 3 cancels the upward operation instruction or the downward operation instruction for each escalator facility 2 and stops each escalator facility 2 (step S10). After the safety is confirmed, the control device 3 returns to normal operation and continues control.

  As described above, in this embodiment, when a disaster such as an earthquake occurs, the control device 3 stops the operation of each escalator facility 2 and then makes a voice announcement for switching the operation content. Since the driving direction is switched to the evacuation route side and the operation is resumed, when a disaster such as an earthquake occurs, each escalator facility 2 is driven to go to the evacuation route direction and is in the building. People can be guided to the doorway 16 and evacuated safely.

  Moreover, in this embodiment, when disasters, such as an earthquake, generate | occur | produce and perform the audio | voice announcement which switches the operation content of each escalator facility 2, the escalator facility 2 which can switch a driving direction using each emergency operation indicator 14 is used. Is displayed. For this reason, when a disaster such as an earthquake occurs and each escalator facility 2 that is operated in the opposite direction to the evacuation route direction is stopped and the operation is resumed in the opposite direction, the passenger is made aware of this, Can be evacuated.
