As a result, the first height is also positioned below the lowest position P1. Although not particularly limited, the second height is, for example, preferably 1 mm to 120 mm below the lowest position P1, and for example, 1 mm to 60 mm below the lowest position P1 It is more preferable to have

In addition, the structure of the 1st and 2nd water level detection parts 7 and 8 is not specifically limited. The first and second water level detectors 7 and 8 may be configured to detect the water level, and may be, for example, float type water level detection sensors or electrode type water level detection sensors.

Moreover, the man conveyor 1 may be provided with the outdoor input part 14 arrange|positioned outside machine room 2a, 2b, for example. Various types of information may be input to the input units 9 and 14 . Although not particularly limited, the input units 9 and 14 may be, for example, switches or touch panels.

For example, as in the present embodiment, the processing device 6 includes an acquisition unit 6a that acquires each information (data) from each unit 7, 8, 9, 10, and 14, a storage unit 6b that stores each information, and each information and a control unit 6d for controlling the units 5b and 11 based on each information.

For example, as in the present embodiment, the calculation unit 6c determines the flooded state inside the first machine room 2a based on the detection by the water level detection units 7 and 8, and determines whether the inside of the first machine room 2a is The control unit 6d may be configured to cause the output unit 11 to output abnormality information when it is determined that there is an abnormality due to flooding.

Further, for example, as in the present embodiment, the calculation unit 6c calculates the travel content of step 3b based on the detection of the water level detection units 7 and 8 and the detection of the human detection unit 10, and the control unit 6d calculates The configuration may be such that the driving in step 3b is controlled by controlling the driving source 5b based on the calculation of the part 6c.

Thereby, the processor executes the program stored in the memory, and the respective units 6a to 6d of the processing device 6 are realized by the cooperation of software and hardware.

Further, the processing device 6 may be configured by, for example, one device, or may be configured by, for example, a plurality of devices capable of communicating with each other. Specifically, the units 6a to 6d of the processing device 6 may be provided in one device, for example, or distributed among a plurality of devices that can communicate with each other.

Next, abnormal output control of the man conveyor 1 according to this embodiment will be described with reference to FIG. Abnormal output control is not limited to the following control.

As shown in FIG. 4, when the first water level detection unit 7 detects the water level ("Y" in S1), the output unit 11 outputs the first abnormality information (S2). Accordingly, it can be grasped that the inside of the first machine room 2a has been flooded based on the output of the first abnormality information. As the content of output of the first abnormality information, for example, the display units 11a to 11c may display that entry is prohibited, and the sound units 11d and 11e may emit alarm sounds, for example.

After that, before the second water level detection unit 8 detects the water level ("N" in S3), when the first water level detection unit 7 does not detect the water level ("N" in S4), the output unit 11 stops outputting the first abnormality information (S5). Accordingly, based on the stop of the output of the first abnormality information, for example, it can be grasped that there is no need to check the inside of the first machine room 2a. Therefore, for example, it is not necessary to unnecessarily remove the floor plate 1a to check the inside of the first machine room 2a.

On the other hand, when the first water level detection unit 7 detects the water level (“Y” in S1, “Y” in S4) and then the second water level detection unit 8 detects the water level (“Y” in S3) , the output unit 11 outputs the second abnormality information (S6). Thereby, based on the output of the second abnormality information, for example, it can be grasped that the inside of the first machine room 2a has been flooded to a high position.

For example, the output contents of the second anomaly information from the display units 11a to 11c are different from the output contents of the first anomaly information from the display units 11a to 11c, and the output contents of the second anomaly information from the audio units 11d and 11e are voice The output content of the first abnormality information from the units 11d and 11e may be different. Further, for example, the output contents of the second abnormality information from the display units 11a to 11c are different from the output contents of the first abnormality information from the display units 11a to 11c, and the output contents of the second abnormality information from the sound units 11d and 11e are , and the output contents of the first abnormality information from the audio units 11d and 11e.

Further, for example, the output contents of the second abnormality information from the display units 11a to 11c are the same as the output contents of the first abnormality information from the display units 11a to 11c, and the output contents of the second abnormality information from the sound units 11d and 11e. may be different from the output content of the first abnormality information from the audio units 11d and 11e. In this way, it is preferable that the output content of the second anomaly information from the output unit 11 is different from the output content of the first anomaly information from the output unit 11, but for example, they may be the same.

Then, when the output unit 11 outputs the second abnormality information (S6), the second water level detection unit 8 has not detected the water level (“N” in S7), and the reset input unit 9a outputs the reset information. is input ("Y" in S8), the output unit 11 stops outputting the second abnormality information (S9). As a result, when the output unit 11 outputs the second abnormality information (S6), if the second water level detection unit 8 does not detect the water level ("N" in S7, "N" in S8) , the output unit 11 continues to output the second abnormality information.

Therefore, in order to stop the output of the second abnormality information, it is necessary to input the reset information to the reset input section 9a inside the first machine room 2a, so it is necessary to remove the floor plate 1a. As a result, when inputting reset information to the reset input unit 9a, for example, the inside of the first machine room 2a is checked. In this way, it is possible to appropriately output or stop the output of the first abnormality information and the second abnormality information.

Next, step travel control of the passenger conveyor 1 according to the present embodiment will be described with reference to FIG. Note that step travel control is not limited to the following control.

First, when the water level inside the first machine room 2a rises above the second height (the water level detected by the second water level detector 8), the step 3b goes underwater inside the first machine room 2a. buoyancy may act on the step 3b. If buoyancy acts on the step 3b, for example, there is a possibility that the running of the step 3b will become unstable.

Therefore, as shown in FIG. 7, when the output unit 11 does not output abnormality information (“N” in S11, “N” in S12), the human detection unit 10 detects a person (“N” in S13). "Y"), the standard running of step 3b is executed (S14). As a result, when the output unit 11 outputs abnormal information ("Y" in S11, "Y" in S12), even if the human detection unit 10 detects a person, the stop in step 3b is maintained. .

Therefore, when the second water level detection unit 8 detects the water level and step 3b is stopped, even if the human detection unit 10 detects a person, the stop of step 3b is maintained. As a result, when there is a risk of buoyancy acting on the step 3b, it is possible to prevent the step 3b from traveling even if there is a person on the riding portion 1b.

Further, when the first water level detection unit 7 detects the water level and step 3b is stopped, even if the person detection unit 10 detects a person, the stop of step 3b is maintained. As a result, the water level inside the first machine room 2a rises, causing the second water level detector 8 to detect the water level during the standard running of step 3b (that is, the first machine room It is possible to prevent the water level inside 2a from reaching the second water level).

On the other hand, when the standard running of step 3b is executed (S14), step 3b satisfies the setting condition ("Y" of S15), the standard running of step 3b is completed (S16), and step 3b is , normally stop (S17). At this time, since there is no person on the step 3b, for example, the distance from when the step 3b starts decelerating to when it stops may be a relatively short first distance.

The setting condition may be, for example, that step 3b travels at least one of the set distance and the set time after the person detection unit 10 detects the person last. Although it is not particularly limited, the setting condition is, for example, after the human detection unit 10 last detects a person, the time required to travel the distance of 1/2 round of the traveling unit 3a plus 30 seconds. 3b may run.

By the way, when the second water level detector 8 detects the water level and the output section 11 outputs the second abnormality information (S18 "Y"), the standard running of step 3b is stopped (S19), and step 3b is slowly stopped (S20). As a result, it is possible to prevent the step 3b from traveling when there is a possibility that the step 3b is subject to buoyancy.

At this time, there is a possibility that a person may be on the step 3b. Therefore, when Step 3b makes a slow stop (S20), Step 3b starts deceleration and then slowly stops over a second distance longer than the first distance in the normal stop (S17). As a result, when the step 3b comes to a slow stop, it is possible to suppress large inertia from acting on the person above the step 3b. Although not particularly limited, the second distance may be, for example, 1.5 to 2.0 times the first distance.

Note that if the first water level detector 7 detects the water level and the output unit 11 outputs the first abnormality information (S18 "N"), the standard run of step 3b is continued. As a result, if there is no risk of buoyancy acting on step 3b, the standard running of step 3b can be completed ("Y" in S15, S16).

As described above, as in the present embodiment, the man conveyor 1 includes the structure 2 having the machine rooms 2a and 2b, and the water level inside the machine room (in this embodiment, the first machine room) 2a is set to the first level. a first water level detection unit 7 for detecting reaching a height; a second water level detection unit 8 for detecting when the water level inside the machine room 2a reaches a second height higher than the first height; An output unit 11 for outputting information and a processing device 6 for controlling the output unit 11 are provided, and the processing device 6 outputs to the output unit 11 when the first water level detection unit 7 detects the water level , the first abnormality information is output, and when the output unit 11 outputs the first abnormality information, the processing device 6 detects the first water level before the second water level detection unit 8 detects the water level. It is preferable to configure the output unit 11 to stop outputting the first abnormality information when the detection unit 7 does not detect the water level.

According to such a configuration, the output section 11 outputs the first abnormality information when the first water level detection section 7 detects the water level. On the other hand, when the output unit 11 outputs the first abnormality information, if the first water level detection unit 7 does not detect the water level before the second water level detection unit 8 detects the water level, 11 stops outputting the first abnormality information. Thereby, abnormality information can be output appropriately.

Further, as in this embodiment, the man conveyor 1 includes a reset input section 9a arranged inside the machine room (in this embodiment, the first machine room) 2a, and the processing device 6 includes the When the second water level detection unit 8 detects the water level, the output unit 11 outputs second abnormality information, and the processing device 6 detects that the second water level detection unit 8 has not detected the water level, and Preferably, the output unit 11 is caused to stop outputting the second abnormality information when reset information is input to the reset input unit 9a.

According to such a configuration, the output section 11 outputs the second abnormality information when the second water level detection section 8 detects the water level. Then, when the second water level detection unit 8 has not detected the water level, reset information is input to the reset input unit 9a arranged inside the machine room (in this embodiment, the first machine room) 2a. In this case, the output unit 11 stops outputting the second abnormality information. Accordingly, in order to stop the output of the second abnormality information from the output unit 11 when the second abnormality information is output, it is necessary to input the reset information to the reset input unit 9a inside the machine room 2a.

Further, as in the present embodiment, the person conveyor 1 includes a traveling step 3b and a person detection unit 10 for detecting a person in the riding unit 1b, and the processing device 6 is configured so that the person detection unit 10 detects a person. is detected, the standard running is executed to continue the running of step 3b until the set condition is satisfied, and the second height is a position lower than the lowest position P1 where the step 3b is located at the lowest position When the second water level detection unit 8 detects the water level and the step 3b is stopped, the processing device 6 detects a person even if the person detection unit 10 detects a person, the step A preferred configuration is to maintain the suspension of 3b.

According to such a configuration, when the human detector 10 detects a human, the standard running is executed, and in step 3b, the vehicle runs until the set condition is satisfied, and then stops. By the way, when the water level inside the machine room (in this embodiment, the first machine room) 2a rises above the second height, the step 3b is positioned underwater inside the machine room 2a, and the step 3b buoyancy may act on

On the other hand, when the second water level detection unit 8 detects the water level and step 3b is stopped, even if the human detection unit 10 detects a person, the stop of step 3b is maintained. As a result, when there is a possibility that buoyancy acts on the step 3b, it is possible to prevent the step 3b from traveling even if there is a person on the riding portion 1b.

Further, as in the present embodiment, in the man conveyor 1, the processing device 6 detects the man detection when the first water level detection unit 7 detects the water level and the step 3b is stopped. Even if the unit 10 detects a person, the stop of step 3b is maintained, and the processing device 6 detects the water level during the standard running when the first water level detection unit 7 detects the water level during the standard running. is continued, and the processing device 6 stops the standard running and stops the step 3b when the second water level detection unit 8 detects the water level during the execution of the standard running. .

According to such a configuration, when the first water level detection unit 7 detects the water level and step 3b is stopped, even if the human detection unit 10 detects a person, the stop of step 3b is maintained. be. As a result, the water level inside the machine room (in this embodiment, the first machine room) 2a rises, preventing the second water level detector 8 from detecting the water level during standard running. be able to.

If the first water level detector 7 detects the water level and the second water level detector 8 does not detect the water level during the standard run, step 3b continues the standard run. As a result, the standard run can be completed when there is no risk of buoyancy acting on step 3b.

Further, when the second water level detector 8 detects the water level during the standard running, the standard running is stopped and step 3b is stopped. As a result, it is possible to prevent the step 3b from traveling when there is a possibility that the step 3b is subject to buoyancy.

Further, as in the present embodiment, in the man conveyor 1, after the standard travel is completed, the distance from the start of deceleration in step 3b to the stop is the first distance, and the standard travel is After the second water level detection unit 8 detects the water level during execution, the distance from the start of deceleration in step 3b to the stop is a second distance longer than the first distance. preferable.

According to such a configuration, when the second water level detector 8 detects the water level during standard running, step 3b starts decelerating and stops after taking a long second distance. As a result, when the step 3b stops, it is possible to suppress the large inertia acting on the person above the step 3b.

In addition, the man conveyor 1 is not limited to the configuration of the above-described embodiment, and is not limited to the above-described effects. Moreover, the man conveyor 1 can of course be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or a plurality of configurations, methods, etc., according to various modified examples described below and employ them in the configurations, methods, etc., according to the above-described embodiment.

Further, for example, the first height may be configured to be a position above the lowest position P1.

(4) In the man conveyor 1 according to the above embodiment, at least one of the first and second water level detectors 7 and 8 of the processing device 6 detects the water level, and step 3b is stopped. In this case, even if the human detector 10 detects a human, the stop of step 3b is maintained. However, the passenger conveyor 1 is not limited to such a configuration.

For example, when the first water level detection unit 7 detects the water level and the step 3b is stopped, the processing device 6 causes the human detection unit 10 to detect a person, thereby causing the step 3b to run (for example, , to execute standard running). Further, for example, when the second water level detection unit 8 detects the water level and the step 3b is stopped, the processing device 6 causes the person detection unit 10 to detect a person, thereby causing the step 3b to run. (For example, the standard running is executed).
