Description

  The present invention relates to an elevator system, and more particularly to an elevator hall call registration system in which a visually impaired person guidance block (hereinafter referred to as a guidance block) is installed on the floor of an elevator hall (hereinafter referred to as a landing).

  In general, a hall call button for performing hall call registration is installed on a wall surface near the hall door. The user operates the hall call button to perform hall call registration and call an elevator car (hereinafter referred to as a car) to the hall. In many halls, Braille nameplates are installed on the wall surface in the vicinity of the hall call button in consideration of the operation of the hall call button by a visually impaired person. In some halls, guidance blocks are installed to guide visually impaired people to the entrance (in front of the hall door). However, even using such Braille nameplates and guidance blocks, it has not been easy for visually impaired people to perform hall call registration.

  In view of such circumstances, several techniques have been proposed for the purpose of improving the operability and the like of hall call registration by visually impaired persons. For example, Patent Document 1 inquires whether or not to use an elevator to a visually impaired person with a directional speaker, and when receiving a reply that a microphone uses an elevator, a guidance block that guides to the position of a hall call button An apparatus for projecting a part of a group upward is disclosed. Patent Document 2 discloses a device for preferentially driving a car by detecting that a user is visually impaired when a call button is operated within a certain time after detecting the contact of a Braille nameplate. It is disclosed.

  Further, Patent Document 3 discloses an elevator provided with a guide block row from before a hall call button to before a car operation panel.

  However, since the systems disclosed in Patent Documents 1 to 3 are technologies on the premise that a visually impaired person operates the hall call button, the visually impaired person finds the position of the hall call button by searching. Forced. On the other hand, the system disclosed in Patent Document 4 has a high implementation cost because the voice guidance recognition device is expensive, and the visually impaired needs to indicate the destination direction by voice. There are cases where it is difficult to register for hall calls.

  The objective of this invention is providing the elevator system which can improve the operativity of hall call registration by a visually impaired person, preventing malfunctioning by a passerby etc.

  An elevator system according to the present invention is an elevator system in which a block for guiding a visually impaired person is installed on a landing floor, the detection device detecting a user on a predetermined block for guiding a visually impaired person, and use by the detection device And a control device that performs hall call registration when a person is detected. That is, the detection device monitors a predetermined visually-impaired person guidance block (for example, a visually-impaired person guidance block in front of a landing door), and changes related to the block (for example, a weight change applied to the block, an upper block) The user on the block can be detected.

  According to the above configuration, the visually impaired does not have to operate the hall call button or give an instruction by voice, and stands on a predetermined visually impaired person guidance block that is predetermined as a position for executing hall call registration. It becomes possible to perform hall call registration only.

  Further, the control device preferably performs hall call registration on condition that detection by the detection device has continued for a predetermined time or more. That is, the control device measures the output time of the detection signal output from the detection device, and outputs the measured output continuation time and a predetermined time (stay time) that is predetermined in order to identify the user and the passerby It has a function to compare.

  According to the above configuration, for example, when a detection time is shorter than a predetermined time, such as when a passerby passes a predetermined visually impaired person guidance block that is a monitoring target of the detection device There is no hall call registration. In other words, according to this configuration, the hall call registration is performed when the user stays on the monitored block for a predetermined time or more, so that malfunction due to detection of a passerby or the like (incorrect hall call registration) is prevented. be able to.

  In addition, the control device detects the visually impaired person in front of the landing door after the user who moves along the block row for visually impaired guidance arranged in a row from the predetermined position of the landing to the front of the landing door is detected by the detection device. It is preferable to perform hall call registration on condition that a user on the guidance block is detected. That is, the detection device targets a plurality of blocks of the visually impaired person guidance block row, and the control device or the detection device determines whether or not the detection is made in order from a distance from the entrance / exit as one condition of the hall call registration. judge. Some of the visually impaired person guidance blocks are preferably arranged straight toward the front of the landing door, and the detection device preferably monitors two or more of the blocks arranged straight. .

  According to the above configuration, it becomes easier to identify visually impaired persons who want to use the elevator and passersby, and it is possible to prevent malfunction due to detection of passersby to a higher degree. That is, it is a normal operation of a visually handicapped person who wants to use an elevator to advance to the front of the landing door along the block line for guiding the visually impaired person, but it is not assumed that a passerby performs such an operation. It is.

  Further, the detection device identifies and detects a user on the at least two visually impaired person guidance blocks, and the control device guides visually impaired people corresponding to the hall call registration in the upward and downward directions. It is preferable that the position of the block for use is stored in advance, and the hall call registration in the destination direction stored in advance is performed based on the position of the user detected by the detection device.

  According to the above configuration, the visually impaired person can perform hall call registration specifying the destination direction without operating the hall call button or giving an instruction by voice. That is, it is possible to perform hall call registration corresponding to the destination direction simply by standing on each visually impaired person guidance block that is predetermined as a position corresponding to the hall call registration in the upward and downward directions.

  Moreover, it is preferable that a control apparatus outputs the audio | voice which guides a user from the speaker which outputs an audio | voice to a hall onto the visually impaired person guidance block corresponding to the hall call registration of the destination direction memorize | stored beforehand. Furthermore, it is preferable that the control device outputs a sound for notifying that the hall call registration has been made from the speaker.

  According to the above configuration, the visually handicapped person can move to the target position according to the sound output from the speaker, and can know the completion of the hall call registration by sound.

  In addition, an image sensor that detects the user based on the video of the landing is used as the detection device, and the control device performs landing call registration on the condition that the white cane possessed by the user is detected by the image sensor. Is preferred.

  According to the above configuration, since the white cane is a powerful material for identifying that the person to be detected is a visually impaired person, it becomes easier to identify visually impaired persons and passersby who want to use the elevator, It becomes possible to prevent malfunctions due to detection of passersby to a higher degree.

  According to the elevator system according to the present invention, it is possible to improve the operability of the hall call registration by visually impaired persons while preventing malfunctions caused by passersby.

It is. The elevator system 10 particularly has a function of simplifying hall call registration by visually impaired persons.

  The elevator to which the elevator system 10 is applied is not particularly limited, and may be a hydraulic elevator, a machine room-less elevator, or the like. The elevator is a lifting device that lifts and lowers between the halls 11 where the cars are installed on each floor in the hoistway. The hoistway is a car hoisting passage provided vertically through a building or the like. A pit is provided at the lowermost part of the hoistway, and an upper machine room is provided at the upper part of the hoistway. The upper machine room is, for example, a room provided on the roof of a building, and a hoisting machine and a control device 12 that raise and lower the car are installed in the room. The main rope is wound around the sheave of the hoisting machine with one end connected to the upper part of the car and the other end connected to the counterweight. The main rope is hoisted or sent out by driving the hoisting machine. It goes up and down along the guide rail in the hoistway.

  The car has an indoor space where passengers can board. The car is provided with a car door that is closed during the up-and-down operation and opens when the car reaches the landing 11 and a car door opening and closing device that opens and closes the car door. Further, a destination floor button for designating a destination floor of the car and an opening / closing button for the car door are installed on the wall surface of the car. The in-car operation panel is connected to the control device 12, and an operation signal is transmitted to the control device 12 when a destination floor button or the like is operated.

  The hall 11 is an entrance for a car and is provided on each floor. The hall 11 is provided with a hall door 13 that opens and closes following the car door, a three-sided frame 14 provided around the hall door 13, an indicator 15 that displays the arrival of the car, a hall call button 16, and the like. Yes. The hall call button 16 and the like are connected to the control device 12 and the operation signal is transmitted to the control device 12 as in the car operation panel.

  The hall call button 16 is a button for performing hall call registration. A user who is not visually impaired can register the hall call by operating the hall call button 16 and call the car to the hall 11. In the lowest floor hall 11 shown in FIG. 1, one hall call button 16 for performing hall call registration in the upward direction is installed. On the other hand, as shown in FIGS. 3 and 5 to be described later, two hall call buttons 16 corresponding to the upward direction and the downward direction are usually installed on the intermediate floor other than the lowest floor and the uppermost floor.

  In the hall 11, guide blocks 17 are installed in a row from a predetermined position on the hall floor to the front of the hall door 13. The guide block 17 is a protrusion (an assembly of protrusions) that can be felt on the sole or the like, and has a function of guiding a visually impaired person to the entrance. As shown in FIG. 1, a general guide block can be used as the guide block 17, and a linear block having linear protrusions arranged along the guide direction and a point-like shape having a large number of dotted protrusions. Including blocks. The guide block 17a installed in front of the landing door 13 is a dotted block (warning block) indicating a stop position. In addition, the protrusion shape, arrangement | positioning, etc. of the guidance block 17 can be suitably changed according to the state (design, space, etc.) of the hall 11, etc. Note that some of the guide blocks 17 are preferably arranged straight toward the front of the landing door 13.

  The elevator system 10 includes a detection device that detects a user on the guidance block 17 in order to simplify landing call registration by a visually impaired person. In this specification, a user means a visually impaired person who uses an elevator. However, the detection apparatus determines whether or not a person or the like present on the guidance block 17 to be monitored is a visually impaired person. There is no need to identify. That is, even if the user has no visual impairment, the hall call registration is performed as long as the operation satisfies a condition determined by the determination unit 20 described later.

  As the detection device, various sensors can be used as long as the device can detect whether or not a user is present on the guidance block 17 that is predetermined as a monitoring target. For example, a weight sensor, an image sensor, An optical sensor or the like can be applied. For example, an infrared active sensor or an infrared passive sensor can be used as the optical sensor, and the sensor component can be installed on the ceiling or floor of the hall 11.

  As shown in FIG. 1, a weight sensor 18 a can be installed as a detection device on the back side of a guide block 17 a (shown by a broken line) installed in front of the landing door 13. According to the weight sensor 18a, the user's weight concerning the guidance block 17a can be detected, and the presence of the user can be detected. The weight sensor 18a is not particularly limited as long as it can detect the weight of the user on the guide block 17a. For example, a known sensor such as a load cell type sensor can be used.

  The detection device such as the weight sensor 18a preferably detects a user on at least a guidance block 17 (for example, the central guidance block 17a) installed in front of the landing door 13, and the back side of the guidance block 17 or the landing 11 is preferred. Depending on the form of the detection device such as the ceiling of the user, it is preferable that the user is installed at an appropriate position where the user can be detected. In addition, as shown in FIG. 5 described later, a plurality of detection devices can be installed for one landing 11.

  The hall 11 may be provided with a speaker 19 that outputs sound to the hall 11. The speaker 19 is connected to the control device 12 and outputs a sound or the like notifying completion of hall call registration as will be described in detail later. In addition, the speaker 19 can use the thing of a various form, and can be installed in the vicinity (refer FIG. 1) of the three-way frame 14, a ceiling, the hall call button 16, etc.

  The control device 12 is a device that performs hall call registration based on the detection information of the weight sensor 18a and controls the operation of each element of the elevator uniformly. For example, in addition to the hall call registration, the operation of the hoisting machine is controlled according to the operation signal of the in-car operation panel, and the car is moved up and down. The control device 12 includes a determination unit 20, a registration unit 21, and a notification unit 22 in order to execute hall call registration based on detection information of the weight sensor 18 a.

  The control device 12 includes a CPU, an input device used to input control parameters used when executing the functions of the above means, a recording device that stores the input control parameters, control programs, and the like, A device including an input / output port and the like, and can be configured by a computer. Each function can be realized by executing software. Specifically, it can be realized by executing a part of hall call registration control in a corresponding elevator control program.

  The determination unit 20 of the control device 12 has a function of acquiring detection information (detection signal) from the weight sensor 18a and determining whether or not the detection signal is continuously output for a predetermined time or more. Specifically, the determination unit 20 measures the time during which the output of the detection signal continues when the detection signal is acquired from the weight sensor 18a, and calculates the output duration of the measured detection signal and a predetermined time. Compare. When it is confirmed that the output continuation time has reached a predetermined time or more, a hall call registration permission signal can be output to the registration means 21.

  Here, the predetermined time is required to be a time in which a passerby and a visually handicapped person using an elevator can be identified, and may vary depending on the situation of the hall 11, but is, for example, about 1 to 5 seconds. be able to. As described above, the determination unit 20 measures the detection time of the user by the weight sensor 18a, thereby identifying a passerby who passes the landing 11 by stepping on the guidance block 17a and a visually handicapped person who uses the elevator. It becomes possible.

  The registration unit 21 has a function of performing hall call registration when the determination unit 20 determines that the detection of the user by the weight sensor 18a has continued for a predetermined time or more. That is, the registration means 21 registers the hall call regardless of the operation of the hall call button 16 when a user staying on the guidance block 17a is confirmed, for example, when the permission signal is obtained from the determination means 20. To do. Therefore, visually impaired persons can register the hall call simply and quickly without searching for the hall call button 16. The registration means 21 can also perform hall call registration when the hall call button 16 is operated.

  The notification means 22 has a function of announcing that the hall call registration has been made. For example, when the registration call 21 is completed by the registration unit 21, the notification unit 22 can output a sound such as “Elevator will arrive soon. In addition, when the detection unit 22 acquires the detection signal from the weight sensor 18a, the notification unit 22 can output a sound such as “please wait as it is” to prompt the user to stay on the guidance block 17a to be monitored.

  The operation of the elevator system 10 having the above configuration, in particular, the execution procedure of the hall call registration by the control device 12 will be described with reference to FIG.

  First, a user on the guidance block 17a is detected (S10). This procedure is executed by detecting the weight applied to the guiding block 17a by the weight sensor 18a and acquiring the detection signal by the determination means 20. That is, when a visually handicapped person using an elevator steps on the guide block 17a on which the weight sensor 18a is installed, the weight is detected by the weight sensor 18a and a detection signal is transmitted to the determination means 20 of the control device 12. Is done.

  Next, it is determined whether or not the detection signal acquired from the weight sensor 18a continues for a predetermined time (for example, 5 seconds) or more (S11). This procedure is executed by the function of the determination means 20. When the determination unit 20 obtains the detection signal from the weight sensor 18a (S10), the determination unit 20 starts measuring the output duration of the detection signal, compares the output duration with the predetermined time, and detects the detection time, that is, the guidance block 17a. The residence time of the upper user is determined (S11). The determination unit 20 can output a hall call registration permission signal to the registration unit 21 when it is determined that the detection time (output duration) is equal to or longer than a predetermined time.

  In S11, the hall call registration is performed on the condition that the detection time is determined to be equal to or longer than the predetermined time (on the condition that the hall call registration permission signal is acquired from the determination means 20) (S12). This procedure is executed by the function of the registration means 21. On the other hand, when it is determined in S11 that the detection time is less than the predetermined time, the hall call registration is not performed, and the registration unit 21 resets, for example, a counter that measures the detection time. Therefore, S11 and S12 can prevent malfunction caused by a passerby or the like who passes the hall 11 by stepping on the guide block 17a.

  In S12, when hall call registration is completed, an announcement notifying the completion of registration is made (S13). This procedure is executed by the notification means 22. For example, the notification unit 22 outputs a sound such as “Please wait for a while as the elevator arrives” from the speaker 19.

  As described above, according to the elevator system 10, the weight sensor 18a that detects the weight applied to the guide block 17a and the detection signal from the weight sensor 18a are acquired, and the detection signal continues for a predetermined time or more. Since it comprises the determination means 20 for determining whether it has been output, the registration means 21 for performing hall call registration based on the determination result of the determination means 20, and the control device 12 having the notification means 22, the visually impaired person is guided The hall call registration can be performed only by standing on the block 17a for a predetermined time. Since the detection means 20 determines the detection time by the weight sensor 18a, the hall call registration is not performed even if the passer steps on the guidance block 17a, and the visually impaired person using the elevator and the passerby of the hall 11 are distinguished. It is possible.

  The structure of the elevator system 30 which is 2nd Embodiment is demonstrated using FIG. In addition, in the elevator system 30, the same code | symbol is attached | subjected about the same component as the elevator system 10, and the description is abbreviate | omitted. Here, FIG. 3 shows a hall 31 on the intermediate floor where two hall call buttons 16 in the up direction and the down direction are installed.

  The elevator system 30 uses the plurality of guidance blocks 17 as monitoring targets, distinguishes and detects users existing on the plurality of monitoring target blocks, and performs hall call registration in a predetermined destination direction based on the detection position. Features. As shown in FIG. 3, the elevator system 30 uses one image sensor 33 installed on the ceiling of the hall 31 as a detection device.

  The image sensor 33 acquires a video in front of the landing door 13 with a camera in order to detect a user staying on the guidance blocks 17a, 17b, and 17c installed in front of the landing door 13. The image sensor 33 can extract not only the position of the object but also features such as the number and length by converting the image of the object captured by the camera into a digital signal and performing various arithmetic processes. It is. Therefore, not only the presence or absence of the user staying on each of the guiding blocks 17a, 17b, and 17c by the image sensor 33, but the white cane that the visually handicapped person normally has is the detection target. You can also register for hall calls. As the image sensor 33, a known sensor or the like can be used. For example, a camera of a security device at the hall 11 can be used.

  The elevator system 30 has a function of performing hall call registration corresponding to the up direction or the down direction using the image sensor 33 that distinguishes and detects the position of the user on the guidance blocks 17a, 17b, and 17c. In order to realize this function, the control device 32 includes a voice guidance unit 34 and a destination determination unit 35 in addition to the determination unit 20, the registration unit 21, and the notification unit 22. In addition, the control apparatus 32 has memorize | stored beforehand the position of the guidance block corresponding to the hall call registration of an up direction and a down direction in a memory | storage part. For example, the guidance block 17b can be stored in advance as a position corresponding to the upward direction, and the guidance block 17c can be stored as a position corresponding to the downward direction.

  The voice guiding means 34 of the control device 32 has a function of outputting a voice for guiding the movement from the speaker 19 to the guidance block 17 (for example, 17b, 17c) corresponding to the upward or downward hall call registration. For example, the voice guiding unit 34 detects the user on the guiding block 17a by the determining unit 20, and determines that the detection signal has been continuously output for a predetermined time or more. Announcement to guide the movement to 17c. Here, since the determination by the determination means 20 is for determining whether or not to perform voice guidance, the predetermined time, that is, the required stay time on the guidance block 17a, is set as compared with the case of the elevator system 10. It is preferable to set it short (for example, for 3 seconds). Note that the voice guiding means 34 can make the announcement as described above at predetermined intervals without being based on the detection information of the image sensor 33.

  The destination determination unit 35 has a function of determining the destination direction of the user based on the position of the user detected by the image sensor 33. Specifically, when the presence of the user is detected on the guidance block 17b by the image sensor 33, the destination determination unit 35 determines that the destination is the upward direction, and the presence of the user is detected on the guidance block 17c. Sometimes, the destination is determined to be in the down direction. Then, the registration unit 21 performs hall call registration in the corresponding direction based on the determination result of the destination determination unit 35. In addition, the destination determination means 35 can also set the stay time (for example, 1 second) on the guidance block 17b and the guidance block 17c as a destination determination condition, similarly to the determination means 20.

  The operation of the elevator system 30 having the above configuration, that is, the execution procedure of the hall call registration will be described with reference to FIG.

  First, a user on the guidance block 17a is detected (S30). This procedure is executed by detecting a user on the guidance block 17a by the image sensor 33 and acquiring a detection signal by the determination means 20. That is, when a visually handicapped person or the like who uses the elevator proceeds on the guidance block 17a to be monitored by the image sensor 33, the presence is detected by the image sensor 33, and the detection signal is determined by the determination means 20 of the control device 12. Is transmitted.

  Next, it is determined whether or not the detection signal acquired from the image sensor 33 continues for a predetermined time (for example, 3 seconds) or more (S31). This procedure is executed by the function of the determination means 20. When acquiring the detection signal from the image sensor 33 (S30), the determination unit 20 starts measuring the output time of the detection signal and compares the measured output continuation time with the predetermined time to determine the detection time ( S31). The determination unit 20 can output a guidance permission signal to the voice guidance unit 34 when it is determined that the detection time is equal to or longer than the predetermined time.

  In S31, when the guidance permission signal is acquired from the determination means 20, an announcement is made to request movement to the guidance block 17b or 17c corresponding to the hall call registration in the upward or downward direction (S32). This procedure is executed by the function of the voice guiding means 34. For example, the voice guiding means 34 may say “Please move to the left hand guidance block (17b) if you are coming to the upper floor, and move to the right hand guidance block (17c) if you are coming to the lower floor”. Can be output from the speaker 19. Here, in the control device 32, the guidance block 17b is stored in advance as a position corresponding to the upward direction, and the guidance block 17c is stored as a position corresponding to the downward direction.

  Next, the destination direction of the user is determined based on the position of the user detected by the image sensor 33 (S33). This procedure is executed by detection of a user on the guidance block 17b or 17c by the image sensor 33 and acquisition of a detection signal by the destination determination means 35. The destination determination unit 35 determines that the destination is the upward direction when the detection signal of the user on the guidance block 17b is acquired from the image sensor 33, and determines the destination when the detection signal of the user on the guidance block 17c is acquired. Determined to be in the down direction On the other hand, when the presence of the user is not confirmed in either of the guidance blocks 17b and 17c by the image sensor 33, the destination call determination is not performed and the hall call registration procedure is stopped.

  Next, hall call registration corresponding to the destination determined in S33 is performed (S34). This procedure is executed by the function of the registration means 21. And when hall call registration is completed, the sound which alert | reports that is output from the speaker 19 (S35). This procedure is executed by the notification means 22.

  As described above, according to the elevator system 30, the image sensor 33, the determination unit 20, the registration unit 21, and the notification unit 22 serve as detection devices that distinguish and detect users existing on the guidance blocks 17 a, 17 b, and 17 c. In addition, the destination direction is determined based on the voice guidance means 34 that makes an announcement requesting movement to the predetermined guidance block 17 corresponding to the hall call registration in the upward direction or the downward direction, and the position of the user who has moved according to the announcement. And the control device 32 having the destination determination means 35. Therefore, the visually handicapped person can perform the hall call registration corresponding to the desired destination only by standing on the guide block 17a, the guide block 17b or 17c.

  The structure of the elevator system 50 is demonstrated using FIG. In addition, in the elevator system 50, the same code | symbol is attached | subjected about the same component as the elevator systems 10 and 30, and the description is abbreviate | omitted. Here, FIG. 5 shows a hall 51 on the intermediate floor where two hall call buttons 16 in the up and down directions are installed.

  The elevator system 50 is characterized by detecting a user traveling along a row of guidance blocks 17. As shown in FIG. 5, the elevator system 50 uses a first path sensor 18d installed on the back side of the guidance block 17d and a second path sensor 18f installed on the back side of the guidance block 17f as detection devices.

  As the first and second path sensors 18d and 18f, weight sensors similar to the weight sensor 18a can be used. In addition, the weight sensor 18a installed in the guidance block 17a also functions as a route sensor that specifies the route of the user. The route sensor needs to monitor at least two of the 17 rows of guidance blocks, and when a weight sensor is used as a detection device, at least two or more, preferably three or more are installed.

  The elevator system 50 has a function of detecting a visually handicapped person who travels along the row of the guide blocks 17 by using the first and second path sensors 18d and 18f. With this function, it becomes possible to distinguish visually impaired persons who use the elevator from passers-by passing on some guidance blocks 17 to a higher degree. In order to realize this function, the control device 52 includes a route determination unit 53 in addition to the determination unit 20, the registration unit 21, and the notification unit 22. The control device 52 also includes voice guidance means 34 and destination determination means 35 in order to perform hall call registration corresponding to the destination direction. Here, it is assumed that the control block 52 stores in advance the guidance block 17a as a position corresponding to the upward direction and the guidance block 17d as a position corresponding to the downward direction.

  In the route determination means 53, the first and second route sensors 18d and 18f detect the user moving along the row of the guidance block 17, and then the weight sensor 18a detects the user on the guidance block 17a in front of the landing door. It has a function of determining whether or not a user has been detected. Specifically, the route determination unit 53 determines whether or not detection signals are acquired in order from the second route sensor 18f, the first route sensor 18d, and the weight sensor 18a. That is, the control device 52 performs hall call registration on the condition that a user traveling along the column of the guidance block 17 is detected. The hall call registration corresponding to the destination direction is executed by the functions of the voice guidance means 34 and the destination determination means 35.

  In the elevator system 50, malfunctions caused by passersby can be greatly reduced by detecting the route by the first and second route sensors 18d and 18f, so that the stay time on the guidance block 17a determined by the determination means 20 is not set or stayed The time can be set shorter (eg, 1 second). In addition, the voice guidance means 34, “Please wait if you are coming to the upper floor. If you are coming to the lower floor, please move to the next guidance block (17d) and wait”. Can be output from the speaker 19. Then, the destination determination means 35 determines the destination as the upward direction when the detection signal from the weight sensor 18a is acquired after voice guidance, and determines the destination as the downward direction when the detection signal from the route sensor 18d is acquired.

  The operation of the elevator system 50 having the above configuration, that is, the execution procedure of hall call registration will be described with reference to FIG.

  First, a user on the guidance block 17f is detected (S50). This procedure is executed by detecting the weight applied to the guidance block 17f by the second path sensor 18f and acquiring the detection signal by the path determination means 53. Subsequently, a user on the guidance blocks 17d and 17a is detected (S51, S52). The route determination unit 53 determines whether or not detection signals have been acquired in order from the second route sensor 18f, and subsequently from the second route sensor 18d and the weight sensor 18a. When the route determination unit 53 determines that the detection signals have been acquired in the above order, the route determination unit 53 can output a first permission signal that permits the continuation of the hall call registration procedure to the determination unit 20.

  When the first permission signal is acquired from the route determination unit 53, it is determined whether or not the detection signal acquired from the weight sensor 18a continues for a predetermined time (for example, 1 second) (S53). This procedure is executed by the function of the determination means 20. The determination means 20 measures the output duration of the detection signal and determines the detection time by comparing with the predetermined time (S53). The determination unit 20 can output the second permission signal (guidance permission signal) to the voice guiding unit 34 when it is determined that the detection time is equal to or longer than the predetermined time.

  In S53, when the guidance permission signal is acquired from the determination means 20, a voice requesting movement to the guidance block 17d corresponding to the downward hall call registration is output (S54). This procedure is executed by the function of the voice guiding means 34. Specifically, as mentioned above, "If you are coming to the upper floor, please wait. If you are coming to the lower floor, please move to the next guide block (17d) and wait." Is output.

  Next, the destination direction of the user is determined based on the position of the user detected by the weight sensor 18a or the first path sensor 18d (S55). This procedure is executed by detecting the user on the guidance block 17a or 17d by the weight sensor 18a or the first path sensor 18d and acquiring the detection signal by the destination determining means 35. When the destination determination unit 35 acquires the detection signal of the user on the guidance block 17a from the weight sensor 18a, the destination determination unit 35 determines that the destination is the upward direction, and receives the detection signal of the user on the guidance block 17d from the first path sensor 18d. When acquired, the destination is determined to be in the down direction. On the other hand, when the presence of the user is not confirmed in any of the guidance blocks 17a and 17d, the destination call registration procedure is stopped without performing the destination determination.

  Next, hall call registration corresponding to the destination determined in S55 is performed (S56). This procedure is executed by the function of the registration means 21. And when hall call registration is completed, the sound which alert | reports that is output from the speaker 19 (S57). This procedure is executed by the notification means 22.

  As described above, according to the elevator system 50, the first and second path sensors 18d and 18f arranged to detect the user moving along the row of the guidance blocks 17, and the guidance block in front of the landing door 13 In addition to a weight sensor 18a for detecting a user on 17a, a determination unit 20, a registration unit 21, a notification unit 22, a voice guidance unit 34, and a destination determination unit 35, a detection device (first and second path sensors 18d, 18f and a control device 52 having a route determination means 53 for determining the detection order of the weight sensor 18a), and usually passes along a row of the guide blocks 17 to the front of the landing door 13 and a visually handicapped person. A higher level of identification with people becomes possible.
