[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a wheelchair step escalator having a wheelchair step.

[0002]

2. Description of the Related Art Recently, there is a tendency that wheelchair users go out more often, and such an escalator with a wheelchair step that can be used while the wheelchair user is in a wheelchair is a staircase in a railway station. It is supposed to be installed in.

In such an escalator with a wheelchair step, it is particularly important not to give a psychological burden to the wheelchair user, but it is also essential to improve the driving efficiency of the escalator and the improvement of services for general users. Therefore, conventionally, even when a wheelchair user uses it, he / she can switch to the wheelchair driving without temporarily stopping the escalator during normal driving so that the wheelchair user can use it. .

FIG. 8 shows a schematic structure of such an escalator with steps for a wheelchair. In this case, the escalator 1 connects the plurality of steps 2 endlessly and is installed so as to be inclined between the entrance 3 of the lower floor and the entrance 4 of the upper floor. 2 forms a step.

Biasing devices 5 and 6 are provided at the respective elevator openings 3 and 4 on the upper and lower floors. In the wheelchair mode, these urging devices 5 and 6 form a wheelchair step in which two steps 2 at predetermined positions have their upper surfaces flush with each other. It is designed to restore the step. Here, 7a, 7b, and 7c represent steps for a wheelchair, 8 represents a truss, and 9 represents a three-phase induction motor that is a drive source of the escalator 1.

A staff call button 11 for calling a staff member, a wheelchair changeover switch 12 provided on a parapet of the escalator 1, a driving confirmation button 13, a descending confirmation button 14, a wheelchair driver is provided at each of the elevator doorways 3 on the lower floor. A stop button 15 and a restart button 16 are provided. In addition, a driving entry confirmation button 17, a descending confirmation button 18, a wheelchair operation stop button 19 and a restart button 20 are provided on the elevator door 4 on the upper floor. Each of these buttons 13-20
Is valid in the wheelchair driving mode.

On the other hand, deceleration start limit switches 21 and 22 are provided near the upper and lower floor ends of the escalator 1, and a deceleration limit switch 23, a boarding overrun limit switch 24, and a descending overrun limit switch are provided at the lower floor entrance / exit 3. 25 is also provided, and a boarding deceleration limit switch 26, a boarding overrun limit switch 27, and a landing overrun limit switch 28 are also provided at the upper floor elevator door 4. In addition, each of these switches 21
~ 28 are wheelchair steps 7a, 7 in the wheelchair driving mode
The protrusions (not shown) provided on b and 7c are engaged to operate.

Here, the deceleration start limit switch 21,
Numeral 22 designates wheelchair steps 7a, 7b, 7c for the respective elevator doors 3,
4 detects the deceleration start position for deceleration, and the boarding deceleration limit switches 23, 26 detect the deceleration start position for decelerating the wheelchair steps 7a, 7b, 7c when the wheelchair Q is boarded. The boarding overrun limit switches 24 and 27 are used for the wheelchair steps 7a that are traveling at a very low speed at the respective elevator doors 3 and 4 when the wheelchair Q is boarded.
It is detected that 7b and 7c are still traveling even if they have passed a predetermined position, for example, a position where the boarding should be completed, and the overrun limit switches 25 and 28 are used to move the respective elevator doors 3 when the wheelchair Q descends. It is detected that the wheelchair steps 7a, 7b, 7c which are traveling at a slight speed at 4 still continue traveling even if they have passed a predetermined position, for example, a position where completion of dismounting.

In the escalator with steps for wheelchair constructed in this way, as shown in FIG. 9, first, after confirming that transportation of general passengers is completed, the wheelchair changeover switch 12 is operated at time a. The escalator 1 is switched from the normal driving mode to the wheelchair driving mode, the biasing devices 5 and 6 form the wheelchair steps 7a, 7b and 7c, and the escalator 1 travels in the wheelchair driving mode. Then, when the wheelchair step 7a approaches the elevator door 3 on the lower floor, the time b
When the boarding deceleration limit switch 23 is operated, the escalator 1 is decelerated and is operated at a low speed of 3.5 m / min, for example. This speed is such a speed that the wheelchair Q can easily get on the escalator 1 and that the caretaker can operate the escalator 1 with a margin.

From this state, when the wheelchair Q gets on the escalator 1 at time c, and then the attendant operates the driving boarding confirmation button 17 at time d, the escalator 1 accelerates to drive at the specified speed of 30 m / min. To be done.

After that, when the wheelchair step 7a approaches the elevator door 4 on the upper floor and the deceleration start limit switch 22 operates at time e, the escalator 1 is decelerated again, and is operated at a low speed of 7.5 m / min, for example. It From this state, the wheelchair Q is moved down from the escalator 1 at the time f, and then the caretaker at the time g presses the confirmation button 18 for getting off.
When is operated, the escalator 1 returns to normal operation,
It will be operated at a normal speed (30 m / min).

Therefore, according to the control of the escalator with a wheelchair step, the efficiency without giving a psychological burden to the wheelchair user and even temporarily stopping the escalator when getting on and off the wheelchair. Has achieved good driving.

By the way, recently, for the purpose of relieving the structural restrictions of buildings and the fear of high-lift escalator,
A so-called escalator with an intermediate landing has been developed, which has a horizontal landing in the middle of the escalator.

Also for such an escalator with an intermediate landing, there has been a demand for an escalator having the above-described operation system of an escalator with steps for wheelchairs.

[0015]

However, when such an escalator with an intermediate landing is operated in the same manner as the above-described escalator with steps for wheelchairs, after the wheelchair user gets on the escalator, the escalator is regulated. When the vehicle is accelerated to a speed of 30 m / min, it will pass through the middle landing area while maintaining the specified speed. However, at the landing part in this middle part, the specified speed is 3
Since the inclination of the escalator changes at 0 m / min, some wheelchair users may feel fear. In particular, in the case of the descending operation, this tendency is noticeable at a position where the vehicle passes through the horizontal landing part in the middle part and then enters the inclined part.

When the wheelchair is inadvertently moved in the horizontal landing part in the middle part and is displaced from the predetermined wheelchair mounting position, the wheelchair does not become horizontal when it enters the inclined part and remains tilted. There is also a problem that it causes danger.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a control device for an escalator with steps for a wheelchair that can safely transfer a wheelchair user even in an escalator with an intermediate landing. To do.

[0018]

The present invention provides a structure in which a plurality of steps are connected endlessly so as to be inclined between the entrances of the upper and lower floors so that the vehicle can travel, and a horizontal landing is provided in the middle of the traveling path. None, in a control device for an escalator with steps for a wheelchair capable of forming a step for a wheelchair using a plurality of steps, the wheelchair steps traveling between the entrances and exits of the upper and lower floors have reached the landing. Detecting means, second detecting means for detecting that the wheelchair step has passed the landing, and predetermined detection information by the detection outputs of the first and second detecting means. And information notifying means.

Further, according to the present invention, the traveling speed of the wheelchair steps passing through the landing is reduced during the period from the detection output of the first detecting means to the detection output of the second detecting means. It is configured to have a speed reduction means.

Further, the present invention has a driving direction detecting means for detecting a driving direction of the wheelchair steps which travels between the entrances and exits of the upper and lower floors, and is adapted to the predetermined driving direction of the driving direction detecting means. The detection output allows the deceleration operation of the deceleration means.

Further, the present invention is configured so as to have a selecting means for selectively setting the decelerating operation in the decelerating means. Further, according to the present invention, the notification means is composed of at least one of a voice message generation means, an alarm means, and a display means.

[0022]

As a result, according to the present invention, in an escalator with a wheelchair step which has a landing in the middle of the running path, the first detecting means for detecting that the wheelchair step has reached the landing and the wheelchair step. Since the predetermined information can be notified by the detection output of each of the second detection means for detecting the passage through the landing, even if the ride comfort of the escalator changes when passing through the landing, the user can get on the wheelchair steps. It is possible to give appropriate attention to wheelchair users,
Unnecessary fear for wheelchair users can be eliminated.

Further, according to the present invention, the running speed of the wheelchair steps passing through the landing is reduced during the period from the detection output of the first detecting means to the detection output of the second detecting means. Therefore, the wheelchair user can be safely transferred until the vehicle passes the landing where the traveling state of the escalator changes.

Further, according to the present invention, the driving direction of the wheelchair steps is detected by the driving direction detecting means, and the wheelchair passing through the landing is provided only when the detected output corresponds to the predetermined driving direction. Since it is possible to reduce the running speed of the steps, by applying the deceleration driving only to the downhill driving, which is particularly fearful, it is possible to remove unnecessary fear of the wheelchair user in this downhill driving, In addition, as for the uphill operation, since the operation can be performed in the normal operation without decelerating, the operation efficiency of the escalator can be improved.

Further, according to the present invention, since the deceleration operation of the wheelchair steps passing through the landing can be selectively set, it is possible to perform the deceleration operation in the intermediate landing of the escalator only when necessary. The driving efficiency can be further improved.

According to the present invention, a voice message, an alarm, a display or the like can be used as a means for giving attention to a wheelchair user when passing a landing. Can be displayed, and the means for alerting wheelchair users can be diversified.

The output circuit 304 of the operation control circuit 30 includes
The drive circuit 36 of the electric motor 9 is connected, and the speaker 42 is connected via the voice synthesizer 41. Here, in the drive circuit 36, the converter device 31 is connected to the three-phase AC power source 34, the inverter device 32 is connected to the converter device 31 via the DC smoothing capacitor 35, and the electric motor 9 is connected to the inverter device 32.

Is controlled by variable speed. Further, the voice synthesizing device 41 generates a message by synthetic voice based on the voice synthesizing signal m output from the output circuit 304 of the operation control circuit 30, and the speaker 42 outputs this message.

In the escalator with an intermediate landing configured as described above, as shown in FIG. 3, after confirming that transportation of ordinary passengers has been completed, the wheelchair changeover switch 12 is operated at time a, and the escalator 1 Is switched from the normal driving mode to the wheelchair driving mode, the biasing devices 5 and 6 form the wheelchair steps 7a, 7b and 7c, and the vehicle is run in the wheelchair driving mode.

If the wheelchair step 7a approaches the elevator doorway 3 on the lower floor and the boarding deceleration limit switch 23 is activated at time b, the escalator 1 is decelerated, and the escalator 1 is decelerated to, for example, 3.5 m / min. Driven at speed. At this speed, the wheelchair Q can easily get on the escalator 1,
Moreover, the speed is such that the attendant can operate the vehicle with a margin.

Then, when the wheelchair Q gets on the escalator 1 at time c and the caregiver operates the driving entry confirmation button 17 at time d, the escalator 1 is accelerated and driven at a prescribed speed of 30 m / min.

From this state, the flowchart shown in FIG. 4 is executed. In this case, in step 401, it is determined whether the intermediate landing gear deceleration start limit switch 43 has operated. In this case, the intermediate landing deceleration start limit switch 43
The escalator 1 operates at a specified speed of 30 m until the
/ Min keeps running.

When the intermediate landing gear deceleration start limit switch 43 operates at time e shown in FIG. 3, step 40
2, the voice synthesis signal m output from the operation control circuit 30 causes the speaker 42 to output the message "The speed is slowing down" through the voice synthesizer 410.

Then, in step 403, the escalator 1 is decelerated, and the operation is shifted to a low speed operation of 7.5 m / min, for example. Further, in step 404, the voice synthesis signal m output from the operation control circuit 30 causes the speaker 42 to output the message “Enter the horizontal portion.” Through the voice synthesizer 410, and further to step 40.
In the same manner, the message “Please do not move the wheelchair from the predetermined position.” Is output from the speaker 42 at step 5.

Then, in step 406, it is determined whether the intermediate landing passage confirmation limit switch 44 has operated. In this case, the message "Please do not move the wheelchair from the predetermined position." In step 405 is repeated until the intermediate landing passage confirmation limit switch 44 operates.

If any abnormality occurs, the wheelchair operation stop button 51 or 53 is operated to suspend the operation of the escalator 1 and restart if safety can be confirmed. The operation of the escalator 1 may be restarted by operating the button 52 or 54.

Thereafter, when the intermediate landing passage confirmation limit switch 44 operates at time f shown in FIG. 3, step 40
7, the voice synthesis signal m output from the operation control circuit 30 causes the speaker 42 to pass through the voice synthesizer 410.
The message "The speed will be faster." Is output, and in step 408, the escalator 1 is accelerated and operated at the specified speed of 30 m / min.

After that, when the wheelchair step 7a approaches the elevator door 4 on the upper floor and the deceleration start limit switch 22 is operated at time g, the escalator 1 is decelerated again and is operated at a low speed of 7.5 m / min, for example. It From this state, the wheelchair Q is moved down from the escalator 1 at time h, and then the caregiver descends at time i at the confirmation button 18
When is operated, the escalator 1 returns to normal operation,
It will be operated at a normal speed (30 m / min).

In the above, the case where the wheelchair user uses the ascending escalator has been described, but the same applies to the case where the descending escalator is used. Therefore, according to such a first embodiment, in the escalator with an intermediate landing having the intermediate landing 101 in the middle of the escalator 1, the intermediate landing gear deceleration start limit switch 43 for detecting that the wheelchair step has reached the landing, 45,
Since the wheelchair user can be given a proper attention by a voice message according to the detection outputs of the intermediate landing passage confirmation limit switches 44 and 46 that detect that the wheelchair steps have passed the landing, the landing can be performed. When passing, the wheelchair user is not given unnecessary fear, and safe driving can be secured.

Further, the traveling speed of the wheelchair steps passing through the landing is reduced from the detection output of the intermediate landing deceleration start limit switches 43 and 45 to the detection output of the intermediate landing passage confirmation limit switches 44 and 46. As a result, wheelchair users can be safely transported until they pass the landing, which changes the escalator running state.
It is possible to secure driving safety. (Second Embodiment) In the second embodiment, deceleration at the intermediate landing is only for downhill driving which is particularly fearful. In this case, the escalator with an intermediate landing used in the second embodiment is the same as that in FIG. 1, and the operation control device of the escalator with an intermediate landing is the input circuit 303 of the operation control circuit 30 shown in FIG. In addition, as shown by a broken line in the drawing, a driving direction signal n for instructing an ascending or descending driving direction is input, and the CPU 301 side determines the ascending or descending driving direction based on the driving direction signal n. . Others are the same as in FIG.

However, in such a structure, when the wheelchair user gets on the escalator 1 and the attendant operates the driving boarding confirmation button 17, the escalator 1 is accelerated to a specified speed of 30 m / min. From the state, the flowchart shown in FIG. 5 comes to be executed. In this case, in step 501, it is determined whether the intermediate landing gear deceleration start limit switch 43 has operated. In this case, the escalator 1 continues to run at the specified speed of 30 m / min until the intermediate landing gear deceleration start limit switch 43 operates.

When the intermediate landing gear deceleration start limit switch 43 operates, it is determined in step 502 whether the driving direction of the escalator 1 is a down driving. In this case, the driving direction of the escalator 1 is determined by the driving direction signal n.

If it is determined that the vehicle is going down, the process proceeds to step 503, where the voice synthesis signal m output from the operation control circuit 30 causes the voice synthesizer 410 to pass through the speaker 42 to "slow the speed." Is output.

Then, in step 504, the escalator 1 is decelerated, and is moved to a low speed operation of, for example, 7.5 m / min. In step 505, the voice synthesis signal m output from the operation control circuit 30 causes the speaker 42 to output the message “Enter the horizontal portion.” Through the voice synthesizer 410.
In the same manner, the message "Do not move the wheelchair from the predetermined position." Is displayed from the speaker 42 at 6.

Then, in step 507, it is determined whether the intermediate landing passage confirmation limit switch 44 has operated. In this case, the message "Please do not move the wheelchair from the predetermined position" in step 506 is repeated until the intermediate landing passage confirmation limit switch 44 operates.

Thereafter, when the intermediate landing passage confirmation limit switch 44 is operated, the routine proceeds to step 508, and it is judged again whether the driving direction of the escalator 1 is the down driving. When it is determined that the driving direction is also the down driving, the speaker 4 is passed through the voice synthesizing device 410 by the voice synthesizing signal m output from the driving control circuit 30 in step 509.
A message of "speed increases." Is output from No. 2, and in step 510, the escalator 1 is accelerated again and is operated at the specified speed of 30 m / min.

On the other hand, when the driving direction of the escalator 1 is the upward driving, it is determined in step 502 that the driving is not the downward driving by the driving direction signal n. Then, step 503,
Step 504 is skipped and step 505 is proceeded to, where the speaker 42 outputs the message "Enter horizontal section". If it is determined in step 508 that the driving direction signal n does not indicate that the vehicle is not downhill, step 50
9. Step 510 is skipped and the process is immediately terminated.

Therefore, according to such a second embodiment,
In the intermediate landing 101 of the escalator 1, the deceleration is performed only in the downhill driving, which is particularly fearful, and the uphill driving is performed in the normal driving without decelerating, so that the safety of the wheelchair user is improved. At the same time, the operating efficiency of the escalator can be improved. (Third Embodiment) In the third embodiment, only the message is output without deceleration at the intermediate landing.
In this case, the escalator with an intermediate landing and the operation control device for the escalator with an intermediate landing used in the third embodiment are the same as those in FIGS. 1 and 2 described above.

With such a structure, when the wheelchair user gets on the escalator 1 and the attendant operates the driving boarding confirmation button 17, the escalator 1 is accelerated to a specified speed of 30 m / min. From the state, the flowchart shown in FIG. 6 comes to be executed. In this case, in step 601, it is determined whether the intermediate landing gear deceleration start limit switch 43 has operated. In this case, the escalator 1 continues to run at the specified speed of 30 m / min until the intermediate landing gear deceleration start limit switch 43 operates.

When the intermediate landing gear deceleration start limit switch 43 operates, the process proceeds to step 602, and the voice synthesis signal m output from the operation control circuit 30 causes the voice synthesizer 410 to pass through the speaker 42 to "enter the horizontal portion. . "Message is output, and further, step 60
Similarly, at 3, the speaker 42 gives a message "Please do not move the wheelchair from a predetermined position."

Then, in step 604, it is determined whether the intermediate landing passage confirmation limit switch 44 has operated. In this case, the message "Please do not move the wheelchair from the predetermined position" in step 603 is repeated until the intermediate landing passage confirmation limit switch 44 operates.

After that, when the intermediate landing passage confirmation limit switch 44 operates, the processing is terminated. Therefore, according to such a third embodiment, the intermediate landing 1 of the escalator 1
In 01, not only deceleration is performed, but only the message is output and the necessary attention can be given to the wheelchair user appropriately, so safety is secured by removing unnecessary fear of the wheelchair user. In addition, the deceleration operation of the escalator 1 at the intermediate landing 101 can be minimized, and the operation efficiency of the escalator can be further enhanced. (Fourth Embodiment) In the fourth embodiment, the deceleration of the wheelchair steps at the intermediate landing can be selectively set. In this case, the escalator with an intermediate landing used in the fourth embodiment is the same as that in FIG. 1, and the operation control device of the escalator with an intermediate landing is the input circuit 303 of the operation control circuit 30 shown in FIG. In addition, as shown by the broken line in the drawing, the deceleration changeover switch 48 is connected, and the other parts are the same as in FIG. Here, the deceleration changeover switch 48 selectively sets whether or not the deceleration operation of the wheelchair steps at the intermediate landing 101 is possible.

However, in such a structure, when the wheelchair user gets on the escalator 1 and the attendant operates the driving boarding confirmation button 17, the escalator 1 is accelerated to a specified speed of 30 m / min. From the state, the flowchart shown in FIG. 7 comes to be executed. In this case, in step 701, it is determined whether the intermediate landing gear deceleration start limit switch 43 has operated. In this case, the escalator 1 continues to run at the specified speed of 30 m / min until the intermediate landing gear deceleration start limit switch 43 operates.

When the intermediate landing deceleration start limit switch 43 operates, it is determined in step 702 whether the deceleration changeover switch 48 selects the deceleration operation. Here, when it is determined that the deceleration operation is selected, the process proceeds to step 703, where the voice synthesis signal m output from the operation control circuit 30 causes the voice synthesizer 410 to pass through the speaker 42 to "slow the speed. . ”Message is output.

Then, in step 704, the escalator 1 is decelerated, and the escalator 1 is shifted to low speed operation of, for example, 7.5 m / min. Further, in step 705, the voice synthesis signal m output from the operation control circuit 30 causes the speaker 42 to output the message “Enter the horizontal portion.” Through the voice synthesizer 410, and further to step 70.
In the same manner, the message "Do not move the wheelchair from the predetermined position." Is displayed from the speaker 42 at 6.

Then, in step 707, it is determined whether the intermediate landing passage confirmation limit switch 44 has operated. In this case, the message "Please do not move the wheelchair from the predetermined position" in step 706 is repeated until the intermediate landing passage confirmation limit switch 44 operates.

After that, when the intermediate landing passage confirmation limit switch 44 is operated, the routine proceeds to step 708, and it is judged again whether or not the deceleration changeover switch 48 selects the deceleration operation. If it is determined that the deceleration operation is also selected here, in step 709, the voice synthesis signal m output from the operation control circuit 30 causes the voice synthesizer 410 to "speed up faster" than the speaker 42. The message is output, and in step 710, the escalator 1
Is accelerated again and is operated at a specified speed of 30 m / min.

On the other hand, when the deceleration changeover switch 48 has not selected the deceleration operation, it is determined in step 702 that the deceleration operation has not been selected. Then, step 70
3. Skip step 704 and proceed to step 705, where the speaker 42 outputs the message "Enter horizontal section." If it is determined in step 708 that the deceleration operation is not selected, steps 709 and 710 are skipped and the process is immediately terminated.

Therefore, according to such a fourth embodiment,
The deceleration of the escalator 1 at the intermediate landing 101 is left to the discretion of the wheelchair user who uses the escalator 1 and can be arbitrarily selected. Therefore, the deceleration operation of the escalator 1 at the intermediate landing 101 should be performed only when necessary. Therefore, the operating efficiency of the escalator can be further improved. (Fifth Embodiment) In the fifth embodiment, a chime and a display device are provided in addition to the voice synthesizer 41 as means for calling attention to a wheelchair user. In this case, the escalator with an intermediate landing used in the fifth embodiment is
The operation control device for the escalator with an intermediate landing is similar to that shown in FIG. 1, and the chime 49 and the display 50 are connected to the output circuit 304 of the operation control circuit 30 shown in FIG. 2 and the others are the same as in FIG.

By doing so, not only the message output from the speaker 42 by the voice synthesizer 41 but also the warning sound by the chime 49 and the visual display by the display 50 can be displayed, and the wheelchair user can be warned. The means for urging people can be diversified, and the attention can be surely transmitted. The present invention is not limited to the above-mentioned embodiments, and can be carried out by appropriately modifying it without departing from the scope of the invention.

[0067]

As described above, according to the present invention, an appropriate fear is given to a wheelchair user when he / she walks on a landing, by prompting the wheelchair user on a wheelchair step with appropriate attention. The mind can be removed, and the transport speed of the wheelchair user can be secured by reducing the traveling speed of the wheelchair steps that pass through the landing. Further, since the deceleration operation when passing through the landing can be selectively performed, it is possible to improve the operation efficiency of the escalator.
