Detailed Description
Embodiment mode 1
Hereinafter, in order to explain the present invention in more detail, a mode for carrying out the present invention will be described with reference to the drawings.
Fig. 1 is a perspective view of a landing operating panel unit 1 for an elevator according to embodiment 1 of the present invention. Fig. 2 is a structural diagram of the unit 1. The unit 1 includes an optical sensor 2, a display unit 3, a storage unit 4, a determination unit 5, a communication unit 6, and a housing 7. The frame 7 has a rectangular parallelepiped shape. One surface of the housing 7 serves as a mounting surface for a character placement surface 10 separated from the housing 7. The display unit 3 is formed on the surface of the frame 7 facing the mounting surface. The optical sensor 2 is mounted on a surface of the housing 7 other than the surface facing the mounting surface.
Fig. 3 is a diagram showing a state in which the unit 1 is mounted on the character arrangement face 10. The character arrangement surface 10 is formed on a wall surface of a hall of an elevator on each floor of a building, for example. A plurality of characters or character strings for designating the destination floors of the elevators are arranged on the character arrangement surface 10.
The optical sensor 2 is composed of an optical sensor such as an infrared sensor, for example, and detects the position coordinates of an object such as a user's finger approaching the character placement surface 10.
The detection of the position coordinates of the object or the like by the optical sensor 2 will be described with reference to fig. 4A, 4B, and 4C. Fig. 4A is a front view of the landing operating panel unit 1 of the elevator mounted on the character placement surface 10. Fig. 4B is a side view thereof. Fig. 4C is a plan view thereof. In embodiment 1, as shown in fig. 4C, the optical sensor 2 is attached to the lower surface of the housing 7 of the unit 1.
As shown in fig. 4A, 4B, and 4C, the center of the light-emitting surface of the optical sensor 2 is defined as O. A plane passing through the center O and perpendicular to the character disposition plane 10 is designated as S. Further, an object such as a user's finger to be detected by the optical sensor 2 is denoted by T. The optical sensor 2 measures the distance d from the center O to the object T. The optical sensor 2 is provided with W as a plane perpendicular to the character placement plane 10 among planes including line segments connecting the center O and the object T, and measures an angle θ formed by the plane W with respect to the plane S. The optical sensor 2 outputs the detected distance d and angle θ to the determination unit 5 as position coordinates.
The storage unit 4 stores information (hereinafter, referred to as positional coordinate information) in which a plurality of characters or character strings arranged on the character arrangement surface 10 are associated with respective positional coordinates of the plurality of characters or character strings. Here, when the position coordinates of an arbitrary character are X, X is constituted by, for example, a distance from the center O to the character, and an angle θ formed by a plane perpendicular to the character disposition plane 10 and including a line segment connecting the center O and the character with respect to the plane S. However, the position coordinates are not limited to points, and are values having a width corresponding to the size of the font of each character. In addition, the positional coordinate information stored in the storage unit 4 can be rewritten in association with a change in the arrangement of the characters or character strings on the character arrangement surface 10. This rewriting is performed, for example, by wireless communication with an external terminal that stores position coordinate information obtained by changing the arrangement of characters or character strings.
The determination unit 5 compares the position coordinates of the object detected by the optical sensor 2 with the position coordinates of the plurality of characters or character strings stored in the storage unit 4, and determines which character or character string is designated by the object. The determination unit 5 outputs the destination floor indicated by the character or character string determined to be specified to the communication unit 6 as input operation information. The determination unit 5 may output the input operation information to the display unit 3 in addition to the communication unit 6.
The communication unit 6 communicates with an external elevator group management control device 9. The communication unit 6 transmits the input operation information acquired from the determination unit 5 to the group management control device 9. The group management control device 9 determines which elevator of the plurality of elevators is allocated to the destination based on the input operation information received from the communication unit 6, and transmits the number information of the elevator to the communication unit 6 as the determination result. For example, when the elevator is 2 elevators, i.e., an elevator a and an elevator B, and it is determined that the elevator a is allocated, the group management control device 9 transmits the number information to the communication unit 6 as the determination result. The communication unit 6 outputs the received number information to the display unit 3.
The display unit 3 displays the number of the elevator selected by the group management control device 9 based on the number information acquired from the communication unit 6. Here, the display unit 3 may display the destination floor together with the number based on the input operation information acquired from the determination unit 5. Fig. 3 shows an example of display of the display unit 3.
Next, an example of the hardware configuration of the unit 1 will be described with reference to fig. 5A and 5B. The functions of the determination unit 5, the communication unit 6, and the display unit 3 of the unit 1 are realized by a processing circuit. The Processing circuit may be dedicated hardware or may be a cpu (central Processing unit) that executes a program stored in a memory. The CPU is also called a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, a processor, and a dsp (digital Signal processor).
Fig. 5A is a diagram showing an example of a hardware configuration in a case where the functions of the determination unit 5, the communication unit 6, and the display unit 3 of the unit 1 are realized by the processing circuit 100 which is dedicated hardware. The processing circuit 100 may be a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an asic (application Specific Integrated circuit), an fpga (field Programmable Gate array), or a combination thereof. The functions of the determination unit 5, the communication unit 6, and the display unit 3 may be realized by combining individual processing circuits 100, or the functions of these units may be realized by one processing circuit 100.
Fig. 5B is a diagram showing an example of a hardware configuration in a case where the functions of the determination unit 5, the communication unit 6, and the display unit 3 of the unit 1 are realized by the CPU102 executing the program stored in the memory 101. The memory 101 may constitute the storage unit 4. In this case, the functions of the determination unit 5, the communication unit 6, and the display unit 3 are realized by software, firmware, or a combination of software and firmware. The software and firmware are described as programs and stored in the memory 101. The CPU102 realizes the functions of the determination unit 5, the communication unit 6, and the display unit 3 by reading and executing the program stored in the memory 101. That is, the unit 1 has a memory 101 for storing a program or the like for finally executing steps ST1 to ST7 shown in the flowchart of fig. 6 described later. It can be said that these programs cause the computer to execute the steps and methods of the determination unit 5, the communication unit 6, and the display unit 3. Here, the memory 101 is, for example, a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an eprom (Erasable Programmable ROM), an eeprom (electrically Erasable Programmable ROM), a magnetic disk, a flexible disk, an optical disk, a high-density disk, a mini disk, a dvd (digital versatile disc), or the like.
A plurality of characters or character strings for designating the destination floors of the elevators are arranged on the character arrangement plane 10. Fig. 3 shows an example of this configuration. The characters are not limited to characters, but include numerals and signs. The arrangement of the plurality of characters or character strings is not limited to the arrangement of fig. 3, and can be selected within a range that can be recognized by a user. In forming the plurality of characters or character strings, processing methods such as printing, laser marking, and concave-convex processing can be selected, and processing methods in consideration of design can be selected.
The main floor designation portion 11 of the character arrangement surface 10 displays character strings such as "RESTAURANT", "LOBBY" and "PARKING", for example. The main floor is a floor where facilities and the like with many users are located, for example, and a character string or the like indicating facilities and the like installed on the floor is arranged for the main floor.
Numerals 0 to 9 are arranged in a layer number designating section 12 of a character arrangement surface 10. Further, a character of "B" may be arranged when there is an underground floor, and a character of "R" may be arranged when there is a roof floor.
Next, an example of the processing of the unit 1 will be described with reference to a flowchart shown in fig. 6.
First, the determination unit 5 acquires the position coordinates of an object such as a user's finger approaching the character placement surface 10 from the optical sensor 2 (step ST 1). Next, the determination unit 5 compares the position coordinates of the object detected by the optical sensor 2 with the position coordinates of the plurality of characters or character strings stored in the storage unit 4, and determines which character or character string of the plurality of characters or character strings is designated by the object (step ST 2). Next, the determination unit 5 outputs the destination floor indicated by the character or character string determined to be specified to the communication unit 6 as input operation information (step ST 3). Next, the communication unit 6 transmits the input operation information acquired from the determination unit 5 to the group management control device 9 (step ST 4). Next, the communication unit 6 receives the elevator number information, which is the result of the determination that the group management control device 9 determines which of the plurality of elevators is allocated to the destination, based on the input operation information received from the communication unit 6 (step ST 5). Next, the communication unit 6 outputs the received number information to the display unit 3 (step ST 6). Next, the display unit 3 displays the number of the elevator selected by the group management control device 9 based on the number information acquired from the communication unit 6 (step ST 7).
When the determination unit 5 is installed in a building having 10 or more floors, it determines whether or not the position coordinates of an object such as a user's finger that is close to the character placement surface 10 are acquired from the optical sensor 2 within a certain time. For example, when determining that the positional coordinates of the object such as the finger of the user approaching the character placement surface 10 are acquired from the optical sensor 2 times within a certain time period and "2" and "0" are designated, the determination unit 5 outputs "20" as the input operation information to the communication unit 6.
The above description has been given of the case where the main floor designation section 11 and the floor number designation section 12 of the character arrangement surface 10 are arranged below the housing 7 of the unit 1 (fig. 3 and the like). However, this arrangement is not limited to this, and may be arranged on the upper portion or the side portion of the frame 7 of the unit 1. In this case, the optical sensor 2 may be attached to the upper side surface or the side surface of the housing 7, and may be configured to detect an object such as a finger of a user.
In addition, the above description has been made of a case where the character arrangement surface 10 is formed on a wall surface of a hall of an elevator, for example. Next, a landing operating panel 30 of an elevator in which a plate-like operating panel 20 having a character placement surface 10 is provided and the unit 1 and the operating panel 20 are integrated will be described. Fig. 7 is a diagram showing a state in which a landing operating panel 30 of an elevator is attached to a wall surface 100 of an elevator landing.
As the material of the control panel 20, glass, metal, stone, or the like, which is not generally used as the material of the control panel 20, may be selected in addition to resin.
The landing operating panel 30 of the elevator is mounted by bringing the mounting surface of the housing 7 of the unit 1 into contact with the surface of the operating panel 20 on which the character placement surface 10 is formed. As shown in fig. 8, the unit 1 may be divided and attached to the operation panel 20 so as to sandwich the operation panel 20 from the front and back surfaces.
A method of attaching the landing operating panel 30 of the elevator to the wall surface 100 of the landing of the elevator will be described with reference to fig. 9. In this installation, the installation fitting 8 is used. First, the mounting fittings 8 are inserted into the fitting insertion holes 1a, the fitting insertion holes 1a being formed on the mounting surface side of the unit 1. Next, the mounting metal fittings 8 to which the units 1 are coupled are fixed to the wall surface 100 with screws. Thereby, the landing operating panel 30 of the elevator is fixed to the wall surface 100. Further, the leg 31 may be provided at a lower portion of the mounting surface side of the operation panel 20. The legs 31 are stably supported so that the operating panel 20 does not become a cantilever support. The leg 31 formed in a convex shape may directly contact the wall surface 100 or may be fitted into a concave portion provided in the wall surface 100.
As described above, according to embodiment 1, the present invention includes: an optical sensor 2 that detects position coordinates of an object approaching a plurality of characters or character strings arranged to designate a destination floor of an elevator; and a display unit 3 that displays the number of an elevator selected by the elevator group management control device 9 according to a destination floor determined using the position coordinates of the object detected by the optical sensor 2, and therefore, it is possible to obtain the unit 1 for a landing operation panel of an elevator and the landing operation panel 30 of an elevator, which can be realized with a simple configuration and can secure a degree of freedom in design.
Further, according to the means 1 for a hall operating panel of an elevator and the hall operating panel 30 of an elevator of embodiment 1, it is possible to select the arrangement of a plurality of characters or character strings on the character arrangement surface 10 within a range that can be recognized by a user. In forming the plurality of characters or character strings, a processing method in consideration of design can be selected.
In addition, according to the landing operating panel 30 of the elevator of embodiment 1, it is possible to select a material such as glass, metal, stone, or the like which is not generally used as a material of the operating panel 20.
Further, according to the unit 1 for a hall operating panel of an elevator and the hall operating panel 30 of an elevator of embodiment 1, it is possible to cope with a change in the specification of the character placement surface 10 by rewriting the position coordinate information stored in the storage unit 4.
Further, according to the unit 1 for a landing operating panel of an elevator and the landing operating panel 30 of an elevator of embodiment 1, the number of components can be reduced compared to a conventional landing operating panel of an elevator. This can suppress the occurrence rate of a failure.
Further, according to the unit 1 for a landing operating panel of an elevator of embodiment 1, the operating panel 20 does not need to be provided, and the number of components can be reduced.
In the present invention, any component of the embodiment may be modified or omitted within the scope of the invention.
