Description

[Technical Field]

[0001] The present disclosure relates to elevator systems. [Background technology]

[0002] Conventionally, there has been known an elevator system that includes a mobile terminal carried by a user and an elevator control device that receives boarding information indicating the user's destination floor from the mobile terminal and performs call registration using the input boarding information (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-30583 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the configuration of the elevator system described in Patent Document 1, even if the car arrives at the hall due to call registration, if there is not enough space in the car, for example, wheelchair users or stroller users cannot board the car. In this case, the user operates the mobile terminal again to input the boarding information into the elevator control device again, and the elevator control device performs call registration again.

[0005] Even if the elevator arrives at the platform again due to the call registration being performed again, if there is not enough space inside the elevator, wheelchair users or stroller users will not be able to board the elevator. This creates a problem in that it can take a long time for wheelchair users, stroller users, or other specific users to board the elevator.

[0006] The present disclosure has been made to solve the above-mentioned problems, and its purpose is to provide an elevator system that can shorten the time it takes for a user to board the car when the user is a specific user. [Means for solving the problem]

[0007] The elevator system according to the present disclosure comprises a mobile terminal carried by a user, and an elevator control device that receives input boarding information indicating the floor of the hall where the user is located and the user's destination floor, and performs general call registration or priority call registration that takes priority over general call registration using the input boarding information, wherein the mobile terminal or elevator control device has a user determination unit that determines whether the user is a specific user, and a boarding determination unit that determines whether the general call registration was performed and therefore the user was able to board the car that arrived at the hall where the user is located, and the elevator control device performs priority call registration using the boarding information when the user determination unit determines that the user is a specific user and the boarding determination unit determines that the general call registration was performed and therefore the user was unable to board the car that arrived at the hall where the user is located. [Effects of the Invention]

[0008] According to the elevator system of the present disclosure, when a user is a specific user, the time required to board the car can be shortened. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a block diagram showing an elevator system according to a first embodiment. [Figure 2] 2 is a flowchart showing the operation of the elevator system of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0010] Embodiment 1 1 is a block diagram showing an elevator system according to Embodiment 1. The elevator system includes a mobile terminal 1 and an elevator control device 2.

[0011] The mobile terminal 1 includes a user information input unit 11, an acceleration sensor 12, a user determination unit 13, a mobile terminal side communication unit 14, a communication determination unit 15, a boarding determination unit 16, and a call signal output unit 17.

[0012] A dedicated application is pre-installed on the mobile terminal 1. The mobile terminal 1 is provided with an input unit for inputting that the user is a designated user. A designated user is a user who cannot use stairs or escalators and has no means of transportation other than elevators to go up and down. Examples of designated users include wheelchair users and stroller users. When the user operates the input unit of the mobile terminal 1, designated user information indicating that the user is a designated user is input into the user information input unit 11.

[0013] The specific user information input to the user information input unit 11 is output from the user information input unit 11 and input to the user determination unit 13 .

[0014] The acceleration sensor 12 measures the acceleration acting on the mobile terminal 1. The measurement result of the acceleration sensor 12 is output from the acceleration sensor 12 and input to the user determination unit 13.

[0015] The user determination unit 13 determines whether or not a user is a specific user based on whether or not specific user information has been input to the user information input unit 11. Specifically, when specific user information is input to the user information input unit 11 and is output from the user information input unit 11 and input to the user determination unit 13, the user determination unit 13 determines that the user is a specific user.

[0016] Furthermore, user determination unit 13 determines whether or not the user is a specific user based on the measurement results of acceleration sensor 12. Specifically, it determines whether or not the user is a specific user using the waveform of acceleration measured by acceleration sensor 12. When the user carrying mobile terminal 1 is a specific user, the waveform of acceleration measured by acceleration sensor 12 has smaller fluctuations in the vertical component compared to when the user carrying mobile terminal 1 is not a specific user. This allows user determination unit 13 to determine whether or not the user is a specific user based on the measurement results of acceleration sensor 12.

[0017] The result of the determination by the user determination unit 13 is output from the user determination unit 13 and input to the call signal output unit 17 .

[0018] When there is a car (not shown) at the platform where the user is located, the mobile terminal communication unit 14 is capable of wireless communication with a car-side communication unit (not shown) provided in the car. On the other hand, when there is no car at the platform where the user is located, the mobile terminal communication unit 14 is unable to communicate wirelessly with the car-side communication unit.

[0019] When the user is at the hall, the mobile terminal side communication unit 14 is capable of wireless communication with a hall side communication unit (not shown) provided at the hall.

[0020] The call signal output unit 17 performs wireless communication with the elevator control device 2 via wireless communication between the mobile terminal side communication unit 14 and the car side communication unit and wireless communication between the mobile terminal side communication unit 14 and the hall side communication unit.

[0021] The communication determination unit 15 determines whether wireless communication is possible between the mobile terminal side communication unit 14 and the car side communication unit. The determination result of the communication determination unit 15 is output from the communication determination unit 15 and input to the boarding determination unit 16.

[0022] Based on the determination result of the communication determination unit 15, the boarding determination unit 16 determines whether or not the passenger was able to board the car that arrived at the platform by performing a general call registration, which will be described later. Specifically, when the car arrives at a platform where a passenger is present, and the communication determination unit 15 determines that wireless communication between the mobile terminal-side communication unit 14 and the car-side communication unit is not possible, the boarding determination unit 16 determines that the passenger was unable to board the car that arrived at the platform where the passenger is present. The determination that the passenger was unable to board the car that arrived at the platform where the passenger is present indicates that the passenger did not board. On the other hand, when the car arrives at a platform where a passenger is present, and wireless communication between the mobile terminal-side communication unit 14 and the car-side communication unit is possible, the boarding determination unit 16 determines that the passenger was able to board the car that arrived at the platform where the passenger is present. The determination that the passenger was able to board the car that arrived at the platform where the passenger is present indicates that the passenger did not not board.

[0023] The determination result of the boarding determination unit 16 is output from the boarding determination unit 16 and input to the call signal output unit 17.

[0024] The mobile terminal 1 is provided with an input unit for inputting the floor of the platform where the user is located and the floor of the user's destination. When the user operates the input unit of the mobile terminal 1, boarding information indicating the floor of the platform where the user is located and the floor of the user's destination is input to the call signal output unit 17. The determination of the user determination unit 13 and the determination of the boarding determination unit 16 are made when the boarding information is input to the call signal output unit 17.

[0025] When the judgment result of the user judgment unit 13, the judgment result of the boarding judgment unit 16, and the boarding information are input to the call signal output unit 17, the call signal output unit 17 outputs the judgment result of the user judgment unit 13, the judgment result of the boarding judgment unit 16, and the boarding information.

[0026] The elevator control device 2 includes a call registration server 21, an elevator control panel 22, an operation status collection server 23, and an attribute detection server 24.

[0027] The call registration server 21 includes a call signal input unit 211 and a call registration command unit 212. The determination result of the user determination unit 13, the determination result of the boarding determination unit 16, and the boarding information output from the call signal output unit 17 are input to the call signal input unit 211.

[0028] Of the judgment result of the user judgment unit 13, the judgment result of the boarding judgment unit 16, and the boarding information input to the call signal input unit 211, the boarding information is output from the call signal input unit 211 and input to the call registration command unit 212.

[0029] Of the judgment results of the user judgment unit 13, the judgment results of the boarding judgment unit 16, and the boarding information input to the call signal input unit 211, the judgment results of the user judgment unit 13 and the judgment results of the boarding judgment unit 16 are output from the call signal input unit 211 and input to the attribute detection server 24.

[0030] The call registration command unit 212 outputs a general call registration command for the elevator control panel 22 to perform a general call registration, or a priority call registration command for the elevator control panel 22 to perform a priority call registration. The general call registration command or priority call registration command output from the call registration command unit 212 is input to the elevator control panel 22. The priority call registration is a call registration that takes priority over the general call registration.

[0031] The elevator control panel 22 includes a call registration unit 221 and an operation history storage unit 222. A general call registration command or a priority call registration command output from the call registration command unit 212 is input to the call registration unit 221. When a general call registration command is input to the call registration unit 221, the call registration unit 221 performs a general call registration. On the other hand, when a priority call registration command is input to the call registration unit 221, the call registration unit 221 performs a priority call registration.

[0032] Information on the operation rate of the elevator is stored in the operation history storage unit 222. The operation rate of the elevator may be, for example, the current number of call registrations per unit time.

[0033] The operation status collection server 23 includes an operation status determination unit 231. The operation status determination unit 231 acquires information on elevator operation rates from the operation history storage unit 222. Using the information on elevator operation rates acquired from the operation history storage unit 222, the operation status determination unit 231 determines whether the elevator operation rate is greater than a reference value, which is a preset value.

[0034] The determination result of the operating status determination unit 231 is output from the operating status determination unit 231 and input to the attribute detection server 24 .

[0035] The attribute detection server 24 includes a call determination unit 241. The call determination unit 241 receives the determination results of the user determination unit 13, the determination results of the boarding determination unit 16, and the determination results of the operating status determination unit 231.

[0036] The call determination unit 241 uses the determination results of the user determination unit 13, the determination results of the boarding determination unit 16, and the determination results of the operating status determination unit 231 to select either a general call registration command or a priority call registration command and output it to the call registration command unit 212.

[0037] Specifically, when the user determination unit 13 determines that the user is a specific user, the boarding determination unit 16 determines that the user was unable to board the car that arrived at the landing where the user was located because a general call registration was performed, and the operation status collection server 23 determines that the elevator operation rate is greater than a reference value, the call determination unit 241 selects a priority call registration command and causes the call registration command unit 212 to output the priority call registration command.

[0038] On the other hand, when the user determination unit 13 determines that the user is not a specific user, the call determination unit 241 selects a general call registration command and causes the call registration command unit 212 to output a general call registration command. Also, when the boarding determination unit 16 determines that the general call registration has enabled the user to board a car that has arrived at the hall where the user is located, the call determination unit 241 selects a general call registration command and causes the call registration command unit 212 to output a general call registration command. Also, when the operation status collection server 23 determines that the elevator operation rate is not greater than the reference value, the call determination unit 241 selects a general call registration command and causes the call registration command unit 212 to output a general call registration command.

[0039] Next, the operation of the elevator system will be described. Figure 2 is a flowchart showing the operation of the elevator system of Figure 1. First, in step S101, the user operates the mobile terminal 1 to register a call.

[0040] Thereafter, a user determination step is performed in step S102. In the user determination step, the user determination unit 13 determines whether or not the user is a specific user.

[0041] If the user determination unit 13 determines in step S102 that the user is a specific user, the operation flow of the elevator system proceeds to step S103. In step S103, a boarding determination step is performed. In the boarding determination step, the boarding determination unit 16 determines whether or not the user was able to board the car that arrived at the hall where the user was located by performing general call registration.

[0042] In step S103, if the boarding determination unit 16 determines that the user was unable to board the car that arrived at the hall where the user was located due to general call registration, the operation flow of the elevator system proceeds to step S104. The determination that the user was unable to board the car that arrived at the hall where the user was located due to general call registration indicates that the user did not board the car. In step S104, an operation status determination step is performed. In the operation status determination step, the operation status determination unit 231 determines whether the elevator operation rate is greater than a reference value.

[0043] If the operation status determination unit 231 determines in step S104 that the elevator operation rate is greater than the reference value, a priority call registration process is performed in step S105. In the priority call registration process, the call registration command unit 212 outputs a priority call registration command, and the call registration unit 221 performs priority call registration. This completes call registration by the elevator system.

[0044] On the other hand, if the user determination unit 13 determines in step S102 that the user is not a specific user, the operation flow of the elevator system proceeds to step S106.

[0045] Furthermore, in step S103, if the boarding determination unit 16 determines that the general call registration has enabled the user to board the car that has arrived at the hall where the user is located, the operation flow of the elevator system proceeds to step S106. The determination that the general call registration has enabled the user to board the car that has arrived at the hall where the user is located indicates that no failure to board has occurred by the user.

[0046] Furthermore, if the operational status determination unit 231 determines in step S104 that the elevator operation rate is not greater than the reference value, the operation flow of the elevator system proceeds to step S106.

[0047] In step S106, a general call registration process is performed. In the general call registration process, the call registration command unit 212 outputs a general call registration command, and the call registration unit 221 performs general call registration. This completes call registration by the elevator system.

[0048] As described above, the elevator system according to the first embodiment includes the mobile terminal 1 and the elevator control device 2. The mobile terminal 1 is carried by a user. The elevator control device 2 receives boarding information and performs general call registration or priority call registration using the input boarding information. The mobile terminal 1 includes a user determination unit 13 and a boarding determination unit 16. The user determination unit 13 determines whether the user is a specific user. The boarding determination unit 16 determines whether the user was able to board a car that arrived at the hall where the user was located as a result of general call registration. The elevator control device 2 performs priority call registration using the boarding information when the user determination unit 13 determines that the user is a specific user and the boarding determination unit 16 determines that the user was unable to board a car that arrived at the hall where the user was located as a result of general call registration. With this configuration, priority call registration is performed when the user is a specific user, the car arrives at the hall as a result of general call registration, and there is insufficient space in the car. This reduces the time it takes to board a car when the user is a specific user.

[0049] Moreover, in the elevator system according to the first embodiment, the mobile terminal 1 has a user information input unit 11. Specific user information indicating that the user is a specific user is input to the user information input unit 11. The user determination unit 13 determines whether or not the user is a specific user when the specific user information is input to the user information input unit 11. According to this configuration, when the user operates the mobile terminal 1, the user determination unit 13 can determine that the user is a specific user.

[0050] Moreover, in the elevator system according to the first embodiment, the mobile terminal 1 has an acceleration sensor 12. The user determination unit 13 determines whether or not the user is a specific user based on the measurement result of the acceleration sensor 12. With this configuration, the user determination unit 13 can determine whether or not the user is a specific user without the user operating the mobile terminal 1.

[0051] Moreover, in the elevator system according to the first embodiment, the mobile terminal 1 includes a mobile terminal-side communication unit 14 and a communication determination unit 15. When a user is in the car, the mobile terminal-side communication unit 14 is capable of wireless communication with a car-side communication unit provided in the car. When the car arrives at a hall where a user is present, the communication determination unit 15 determines whether wireless communication between the mobile terminal-side communication unit 14 and the car-side communication unit is possible. When the car arrives at a hall where a user is present and the communication determination unit 15 determines that wireless communication between the mobile terminal-side communication unit 14 and the car-side communication unit is not possible, the boarding determination unit 16 determines that general call registration has been performed and therefore the user was unable to board the car that arrived at the hall where the user was present. This simple configuration makes it possible to determine whether general call registration has been performed and therefore the user was able to board the car that arrived at the hall where the user was present.

[0052] Furthermore, in the elevator system according to the first embodiment, the elevator control device 2 includes an operation status determination unit 231. The operation status determination unit 231 determines whether the elevator operation rate is greater than a predetermined reference value. The elevator control device 2 performs priority call registration using the boarding information when the user determination unit 13 determines that the user is a specific user, the boarding determination unit 16 determines that the user was unable to board a car that arrived at the hall where the user is located due to general call registration, and the operation status determination unit 231 determines that the operation rate is greater than the reference value. According to this configuration, priority call registration is performed when the user is a specific user, the car arrives at the hall due to general call registration, there is insufficient space in the car, and the elevator operation rate is greater than the reference value. This makes it possible to prevent a decrease in elevator transportation efficiency due to frequent priority call registrations.

[0053] In the elevator system according to the first embodiment, when the car arrives at a hall where a user is present and the communication determination unit 15 determines that wireless communication between the mobile terminal communication unit 14 and the car communication unit is not possible, the boarding determination unit 16 determines that the user was unable to board the car that arrived at the hall where the user was present because general call registration was performed. However, the present invention is not limited to this configuration. Alternatively, when the car arrives at a hall where a user is present and the communication determination unit 15 determines that wireless communication between the mobile terminal communication unit 14 and the hall communication unit is possible, the boarding determination unit 16 may determine that the user was unable to board the car that arrived at the hall where the user was present because general call registration was performed. Even in this case, a simple configuration can be used to determine whether the user was able to board the car that arrived at the hall where the user was present because general call registration was performed.

[0054] Furthermore, in the elevator system according to the first embodiment, a configuration has been described in which the elevator control device 2 includes the operation status determination unit 231. However, this configuration is not limited to this. The elevator control device 2 may also be configured not to include the operation status determination unit 231. In this case, when the user determination unit 13 determines that the user is a specific user and the boarding determination unit 16 determines that the user was unable to board the car that arrived at the hall where the user was located because general call registration had been performed, the elevator control device 2 performs priority call registration using the boarding information.

[0055] In the elevator system according to the first embodiment, the portable terminal 1 has been described as having the user information input unit 11 and the acceleration sensor 12. However, this is not the only possible configuration. For example, the portable terminal 1 may have either the user information input unit 11 or the acceleration sensor 12.

[0056] In addition, in the elevator system according to the first embodiment, the mobile terminal 1 has been described as having the user determination unit 13, the communication determination unit 15, and the boarding determination unit 16. However, this configuration is not limited to this. The elevator control device 2 may have at least one of the user determination unit 13, the communication determination unit 15, and the boarding determination unit 16.

[0057] Furthermore, in the elevator system according to the first embodiment, a configuration has been described in which the user determination step, the boarding determination step, the operating status determination step, the priority call registration step, and the general call registration step are performed by the user operating the mobile terminal 1. However, this configuration is not limited to this. If boarding information is input in advance into the mobile terminal 1, the user determination step, the boarding determination step, the operating status determination step, the priority call registration step, and the general call registration step may be performed without the user operating the mobile terminal 1.

[0058] Although the elevator system according to the preferred embodiment 1 has been described above, the present invention is not limited to the elevator system according to the above-described embodiment 1. Various modifications and conversions can be made to the elevator system according to the above-described embodiment 1 without departing from the scope of the claims.
