BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. 1 to 5 are views showing an embodiment of the first to third inventions of the present invention.
Is an overall configuration diagram, FIG. 2 is a pressure pattern recognition operation flowchart, FIG. 3 is a pressure pattern explanatory view by a healthy person, FIG. 4 is a wheelchair pressure pattern explanatory view, and FIG. Indicates the same part.

In FIG. 1, 1 is an elevator hall,
2 is a landing door, 3 is a public landing button, 4 is a wheelchair-only landing button, 5 is installed on the landing floor in front of the landing door 2, and a large number of sensors are arrayed to pattern the pressure when a passenger gets on the floor. When the pressure pattern information stored in advance is input, and the pressure pattern from the surface pressure detector 5 is input, the pressure pattern is recognized by referring to the pressure pattern information 6 The pressure pattern recognition means for judging whether a person standing in position 1 is a healthy person, a wheelchair, or a bed.

When the wheelchair-dedicated hall button 4 is pressed, 8 refers to the type of passenger determined by the pressure pattern recognition means 7, and registers the wheelchair-dedicated hall call when the passenger includes a wheelchair or a bed. When the general hall button 3 is pressed, a hall call registration means for registering a normal hall call,
Reference numeral 9 is an elevator control means for instructing the door control means 10 about the door opening time of the hall door 2 according to the type of hall call registered by the hall call registration means 8.

Next, the operation of this embodiment will be described with reference to FIGS.
Will be described with reference to. (1) Pressure pattern recognition operation (FIG. 2) In step S1, the surface pressure detector 5 detects the pressure pattern. In step S2, nozzle filter processing is executed to remove the unnecessary pressure pattern. Then, in step S3, the position of the center of gravity of the pressure pattern subjected to the nozzle filter processing is calculated.

Here, an example of the pressure pattern when a healthy person is standing is shown in FIG. 11 and 12 are pressure distributions on the soles of the feet, and 11a and 12a are pressure distributions 11,
12 is the position of the center of gravity, 13 is the area of the part surrounded by the center of gravity,
M1 is the distance between the left and right center of gravity 11a and 12a, and N1 is the distance between the center of gravity 11a and the center of gravity 12a in the front-rear direction (details will be described later). 4 is an example of a pressure pattern when there is a wheelchair, 14 to 17 are pressure distributions of tires of the wheelchair, 14a to 17a are barycentric positions of the pressure distributions 14 to 17, and 18 is surrounded by a barycentric point. The area of the open portion, M2 is the distance between the left and right centers of gravity 14a, 15a or 16a, 17a, N
2 is also the distance in the front-back direction.

Next, in step S4, the center of gravity positions 11a and 12
a, 14a to 17a, distances M1, N1 and M between the centers of gravity
2, find N2. The distance between the centers of gravity is the distance M in the left-right direction.
1, M2 and the distances N1 and N2 in the front-rear direction are obtained. In the case of a pattern such as a leg of a healthy person with no distance in the front-rear direction, the distance N1 in the front-rear direction may not be detected, but in this case, the distance N1 in the vertical direction is treated as the same as the minimum unit.

In step S5, from the distances M1, N1 and M2, N2 between the centers of gravity, the area 13,
Call for 18. This area is used to determine the pressure pattern. In step S6, the typical pressure pattern information 6 created and stored in advance by the same procedure as above is correlated with the currently created pressure pattern information to determine which stored pattern is similar. To do. Then, in step S7, it is determined to be a "healthy person", and in step S8, it is determined to be a "wheelchair". Here, steps S1 to S8 constitute pressure pattern recognition means.

(2) Hall call registration operation (FIG. 5) It is assumed that the wheelchair-dedicated hall button 4 is pressed at the hall 1. In step S11, it is determined whether there is a wheelchair-only hall call. Since the wheelchair-dedicated hall button 4 has been pressed, the process proceeds to step S12, the pressure pattern output from the surface pressure detector 5 is recognized, and the current situation of the hall 1 is grasped. In step S13, it is determined whether the result of the pressure pattern recognition includes a wheelchair or the like. If the pressure pattern is wheelchair, the process goes to step S14 to register the wheelchair-only hall call.

If the pressure pattern does not include a wheelchair or the like, the process proceeds to step S15 to register a normal hall call. Next, it is assumed that the public hall button 3 is pressed in the hall 1. Since it is determined in step S11 that there is no wheelchair-only hall call, the flow advances to step S16 to determine whether there is a normal hall call. In this case, since there is a normal hall call, the normal hall call is registered in step S15.
When there is neither a normal hall call nor a wheelchair-only hall call,
The process ends.

Then, the elevator control means 9 instructs the door control means 10 to open the door in accordance with the type of the hall call registered in steps 14 and 15, and the hall door 2
The opening time of is changed between general users and wheelchair users. Here, steps S11 to S14 constitute wheelchair exclusive hall call registration means, and steps S16 and S15 constitute normal hall call registration means.

In this way, the wheelchair exclusive landing button 4
If the wheelchair user misuses the wheelchair user, the surface pressure detector 5 needs to actually extend the door opening time. It is possible to increase the length, and it is possible to prevent a significant decrease in service status such as waiting time due to misuse. As a result, it becomes possible to improve the serviceability of the elevator in which the wheelchair-only hall button 4 is installed.

Embodiment 2. FIG. 6 is a hall call registration operation flowchart showing an embodiment of the fourth invention of the present invention. 1 to 4 are also used in the second embodiment. However, the wheelchair exclusive landing button 4 of FIG. 1 is not used. This embodiment is applied when the wheelchair-dedicated hall button 4 is not installed in the hall 1.

It is assumed that the public hall button 3 is pressed in the hall 1. In step S21, it is determined whether there is a hall call.
Since there is a general hall call, the process proceeds to step S22, the pressure pattern output from the surface pressure detector 5 is recognized, and the current situation of the hall 1 is grasped. In step S23, it is determined whether the result of the pressure pattern recognition includes a wheelchair or the like. If the pressure pattern is a wheelchair, step S2
Proceed to 4 to register the wheelchair-only hall call. If the pressure pattern does not include a wheelchair, step S25.
Go to and register a regular hall call.

If it is determined in step S21 that there is no call, the process ends. Here, steps S21 to S2
3, S25 is a normal hall call registration means, step S2
1 to S24 constitute a wheelchair exclusive hall call registration means. In this way, by installing only the general hall button 3, the wheelchair-dedicated hall call and the ordinary hall call are automatically discriminated and registered with only one hall button by the output of the surface pressure detector 5. It becomes possible to do.

[0024]

As described above, according to the first aspect of the present invention, the surface pressure detector is laid on the floor of the hall, and the pressure pattern is output by the object placed on the surface pressure detector. Since the type is determined, it is possible to accurately determine whether the waiting passenger at the hall is a normal person or a wheelchair user.

Further, in the second invention, the area surrounded by the contact points is calculated from the distance between the contact points of the object and the surface pressure detector, and the type of the object is determined from these areas. It is possible to accurately determine whether the passenger waiting at the landing is a healthy person or a wheelchair user.

Further, in the third aspect of the invention, a surface pressure detector is laid on the floor of the hall, and it is determined whether the human body or the vehicle body is detected by the surface pressure detector. When the general hall button is operated, a normal hall call is called. When it is registered and the wheelchair exclusive button is operated and it is determined that the vehicle body is included in the pressure pattern, the wheelchair exclusive hall call is registered, so if the wheelchair exclusive button is misused by a healthy person, it will be misused. It is possible to prevent a significant decrease in service status such as waiting time due to, and improve the serviceability of the elevator.

In the fourth aspect of the invention, a surface pressure detector is laid on the floor of the hall, the human body or the vehicle body is judged by the surface pressure detector, the general hall button is operated, and the vehicle body is displayed in the pressure pattern. If it is determined that it is not included, a normal hall call is registered, and if it is determined that the vehicle body is included in the pressure pattern, a wheelchair-only hall call is registered.
With one hall button, it is possible to automatically distinguish and register a wheelchair-only hall call and a normal hall call.
