Description

[Detailed description of the invention]

[Object of the Invention] (Industrial Application Field) The present invention relates to an elevator control device that performs hall call registration when an elevator user in an elevator hall is detected. (Prior Art) In recent years, with the advancement of information processing technology, the number of intelligent buildings equipped with advanced information and communication technology is increasing. Elevators, which serve as a means of vertical transportation within buildings, are not just transportation devices, but are becoming highly functional as a common place for both the building and its users. Among these, devices that are directly connected to users and elevators are designed with ergonomics in mind, and are designed to improve usability for users, rather than simply pressing a button and waiting for the elevator to arrive as in the past. , the following various registration devices have been considered. (a) A device that registers a call using a magnetic card (b) A device that registers a call without contact using a wireless card (C) A device that registers a call by touching the image surface (d) A device that recognizes the user's voice A device for registering calls Although such a device can perform the specified function even if it is simply operated, it is necessary to take ergonomic considerations and various conveniences as described by Rico, Ju, and Saito.・Considerations are being given to detecting users in order to improve the performance of users. If the approach is detected and the method of use of 15 is notified, it will be used for the first time (even a person can definitely operate it and if there is no user, 1.1. will be notified), 5 is not available, so it depends on the installation of the device. E) The shift L2 does not increase by 4 degrees. The above-mentioned image (e) is also used, and a device that uses it is a device that places a transparent plate (referred to as a touch panel) on top of the image surface to detect a person's finger, as described in Utility Model Application Publication No. 58-184474. There are some that can be operated by giving instructions using images or by pressing a location. The effectiveness of such a device can be improved by changing its behavior in response to the proximity of a user. In other words, if the general information is displayed in large letters when there is no one in front of the machine, it can be recognized by passengers waiting for the elevator in the distance, and it also has secondary effects such as not making elevator passengers feel the travel time. 7 The device P that sings h/voice recognition in 1.4 is 1. ,．． 2 (7

1. In the case of a noveta, there is a problem that it is difficult to detect. First, the detection by the mat sensor is not effective from a design point of view because the elevator is a part of the building, and the elevator is also in the passageway of the building. Detection using a TV camera is a method of patterning the shape of the user using a TV camera installed on the opposite side, but in order to prevent malfunctions, the design of the floor of the building is difficult to operate. There are problems such as having to limit the number of customers, having to operate even when the lighting is dim, and having restrictions on ceiling height.In addition, the ultrasonic 5 pyroelectric sensor can detect customers over a wide range. However, while dark infrared sensors can solve the problems of ultrasonic and pyroelectric sensors, they have problems measuring the distance from which the user intends to use each device. In addition to the above-mentioned problems, there is also the drawback that the detection is not good depending on the usage status of the elevator.In other words, the elevator is operated by an unspecified number of people. The problem is that users approach the device from multiple directions.1 Specifically, the device is used by children, wheelchair users, and from the side rather than from the front, so conventional detection methods are difficult to detect. The present invention solves the above-mentioned problems and provides an elevator control device that can reliably detect the presence of a user and allow the user to register a hall call. [Structure of the Invention] (Means for Solving the Problem) The present invention aims to solve the problems mentioned above. At the same time, it is installed in the F direction with respect to the vertical direction, so that users can approach it within a predetermined distance.

[7] A plurality of position detection sensors for detecting a situation; and one of the plurality of position detection sensors usually provided in the elevator hall and providing various information to the users. and an information input device for detecting the user and allowing the user to register a hall call. (Function) When any one of the plurality of position detection sensors arranged in the elevator hall at a predetermined angle to each other in the horizontal direction and facing downward in the vertical direction detects the approach of a user. 1. The information input device that normally provides various information to users must be able to register hall calls by users.
User rebellion can be detected reliably. (Example) An example based on the present invention will be described using the drawings. First, installation of the position detection sensor according to the present invention will be explained. In the present invention, a plurality of sensors installed to detect a user are arranged at an angle so that the shape of the user can be captured, and the approach status and presence of the user can be detected at the same time. . FIG. 1 shows the state of user detection according to the present invention. Generally, the elevator information input device [J is attached to the wall of a building or car, and is installed at a height that is easy for users 2 to handle and see. A height of about 1400+m+a is considered to be ergonomically good. On the other hand, the average height of users is about 1600m+m. Also position detection sensor: 3a
・For ~3e, a diffuse reflection type sensor is used to improve accuracy or make it more compact.This diffuse reflection type sensor emits dark infrared rays from itself7 and detects reflected light from the target object. Place 1 [& is to be measured, 700mm
The distance is about 1? measurement h] capability. Therefore, in the present invention, a plurality of position sensors 3a to 3e
As shown in FIG. 1, the sensor is installed horizontally at a predetermined angle to detect users approaching from multiple directions. Furthermore, as shown in FIG. 2, paying attention to the mounting height of the information input bag w1, position sensors 3a to
3e is installed tilting downward. This is the position sensor 3 for user 2 who is 1600iam tall.
The height of 1400 mm for a to 3e is around the neck, which takes into consideration that the detection range will be narrow. That is,
Considering the body of the user 2, the position sensors 3a to 3e are arranged at angles that detect the widest part, so that the user 2 can be covered over a wide range within the sensor detection limit 4 without increasing the size of the information input device 1. Detect. In addition, in this embodiment, five position detection sensors 3a to
- Although the case where 3e is used will be explained, more position detection sensors may be used in order to further increase the accuracy by 1 or to widen the detection range for the user. Next, the configuration of each position detection sensor 3a-3e will be explained using FIG. Each of the position detection sensors 3a to 3e is connected in parallel to a position sensor processing unit 5, which will be described later. The processing unit 5 detects it. The output sections of the position detection sensors 38 to 3e are configured in an open collector type, and the position detection sensor detection section 6 is configured with a photocoupler or the like. Although the position sensors 38 to 3e have been described above as digital outputs, even if the position sensors 38 to 3e are analog outputs, if the position sensor detection section 5 is used as a current input, the distance to the user 2 can be measured at the same time as detection. FIG. 4 shows an elevator hall used in an embodiment of the present invention, and shows a case where a voice recognition microphone 7 is installed to register a user's destination floor by voice. In this embodiment, since the destination floor is input before getting on the elevator, there is no need to register the call in the elevator car, and the destination call is automatically registered by the hall call. 8 is the elevator door, 9 is the elevator! Indicates an indicator. Reference numeral 10 denotes a hall destination call button with a destination floor display lamp that lights up the registered destination floor lamp when the destination floor is registered. Also, in the hall, there is a position detection sensor 3 for detecting elevator users, a sensor lamp 11 that indicates that voice recognition processing is possible, an OK lamp 12 that indicates that voice recognition processing is normal, and an eject lamp 13 that indicates that voice recognition processing is not possible.
This constitutes the information input device 1. A diffuse reflection type dark infrared sensor is used as the position detection sensor 3, thereby making it possible to detect distance without making the user aware of the presence of the sensor. In addition, the output of this position detection sensor 3 usually has a current output of 4 to 20
The position sensor processing unit 5 converts the distance signal from the sensor 3 into a digital lid of about 8 bits as mA. [Sensor lamp] 1. The OK clamp 2 and the reject lamp 13 are integrated and arranged so that they come into view when the elevator user is speaking into the voice recognition microphone 7, as shown in Fig. 4. It's being passed around again. FIG. 5 shows a block diagram of this embodiment. The sensor lamp 11 is a lamp that indicates the start of voice recognition, and when the CPU 14 determines that the value measured by the position detection sensor 3 is within a certain range, the recognition result notification unit 15 consisting of a digital signal is activated. Lights up depending on the output. OK clamp 2 and reject lamp 13 are
As a result of a series of speech recognition processes, if the similarity of the input speech exceeds a certain standard, OK clamp 2 is selected, and if the similarity of the input speech exceeds a certain standard,
In this case, the CPU 14 lights up the reject lamp 13 for 1 to 2 seconds via the recognition result notification section 15 to notify the elevator user 2 of the result. At this time, if the degree of similarity exceeds a certain standard, the CPU 1.4 flashes the result not only on the OK clamp 2 but also on the registration lamp of the destination button 10, and the recognition result is 1 for 2 people using the elevator. performs an action to determine whether or not it is normal. Conventionally, this destination button 10 is
However, by making the registration up-and-down process turn on in logical conjunction with the output result from the voice recognition device, there is no change in J, elevator control section]6 compared to the conventional one. The configuration of the embodiment of the present invention is now fully functional. Similar to normal call input, parallel signals are used between the elevator control section I6 and the operation output section 17. Further, the voice input from the microphone 7 is subjected to voice similarity determination by the voice recognition unit 18, and the result is sent to the CPU and J14. As already explained, the position detection sensor 3 is arranged in the first
When arranged as shown in Figure 2, users 2 can be seen from multiple directions.
It becomes possible to detect the approach of Audio v! , Makoto's call registration is effective mainly when both hands are occupied with luggage, but in this case, the user may end up making a sound regardless of the display on the device itself, and even in that case, if the distance is within 600 mm, Since the user is detected, the voice recognition unit 18 can be operated. Since the voice recognition unit 18 starts the recognition operation after the position detection sensor 3 is turned on, it can distinguish it from surrounding noise and accurately recognize the voice of only the user. FIG. 6 is a display example of the information input device II for registering a call by operating the image screen. The call registration device using the image screen is the 6th one.
As shown in Figure 6(b), the call button is often displayed and waiting for the user, but if the user approaches and is not at 2 according to the detection of the user by the present invention, the button shown in Figure 6(a) is displayed. It can be used as an information display device, and its functions can be expanded. Like the voice recognition device described above, the position sensor 3 can be easily attached to this device as well, and it can be arranged so as not to be noticed by the user. In addition, in the present invention, detection is performed using multiple position sensors, but since the purpose of this is to widen the detection angle, one
Similar functions may be stored within one position sensor. [Effects of the Invention] According to the present invention, it is possible to provide an information input device for an elevator that follows the natural movements of users, so there is an advantage that the information input device, which conventionally could be a hindrance to traffic, can be operated effectively. be. In addition, when a user is not accustomed to a new function such as an information input device, the device is highly reliable by preventing the user from not using it again if the function cannot be realized due to a simple difference in operation method. 5 Next, conventional user detection could not function adequately unless it was installed separately from the information input device or the information input device was made larger, but with the present invention, it can be made smaller and more sophisticated. It is possible to provide a functional information input device.
