Detailed Description
Fig. 1 is a block diagram showing the configuration of an elevator, an elevator display device, and a security gate system according to embodiment 1 of the present invention. The reading unit 1a is connected to an elevator display device 2. The elevator display device 2 and the reader 1a constitute a security gate system 1. The emergency door system 1 and the elevator system 3 constitute an elevator according to embodiment 1. However, the elevator does not necessarily need to include the reading unit 1a, and may include only the elevator display device 2 and the elevator system 3.
The safety door system 1 is provided in a path from an entrance of a building to an elevator hall, for example. The safety door system 1 is provided for the purpose of enhancing safety in a building as a system for restricting entry into the building or restricting use of an elevator. The safety door system 1 is provided with a door (gate), and a user cannot use the elevator unless he or she passes through the door.
The reading section 1a provided in the security door system 1 reads user information for authenticating a user from a portable storage medium carried by the user who wants to pass through the door. The portable storage medium is constituted by, for example, an IC card such as employee id, pass, membership card, a smart phone, a cellular phone, a tag, or the like. The user information contains destination floor information for determining the destination floor of the user. Examples of the destination floor of the user include a living floor of the user, a floor where an office of a work unit of the user is located, and the like. In this way, the reading unit 1a constitutes a user information acquisition unit that acquires user information including the user's destination floor information and inputs the destination floor information to the elevator display device 2.
As shown in fig. 1, a safety door system 1 is connected to an elevator system 3.
In embodiment 1, an elevator in which a plurality of elevator cars are provided and the elevator cars are group-controlled is assumed as an elevator in which the elevator system 3 is provided. All floors from the lowermost floor to the uppermost floor of the building in which the elevator is installed are divided into a plurality of zones. Hereinafter, this area is referred to as a floor area. Examples of the floor area include a lower layer area, an intermediate layer area, and a higher layer area. In the elevator according to embodiment 1, one elevator group is allocated to each floor zone. The elevator group allocated to each floor zone is referred to as a bank hereinafter. Thus, an elevator installed in a building having three floor areas has three banks, and is thus called a three-bank elevator. Likewise, an elevator installed in a building having four floor zones is referred to as a four-bank elevator.
In such an elevator, a service floor at which an elevator car stops is determined for each bank. Specifically, for example, service floors are set for each of the lower-level ladders so that the service floors are from 1 to 9 floors, from 10 to 19 floors, and from 20 to 30 floors, respectively. Therefore, in the elevator hall, the elevator hall is divided into the elevator halls by each bank. Therefore, the user needs to select one landing from among a plurality of landings in the elevator hall in accordance with his/her destination floor. That is, when the user's destination floor belongs to the low floor area, the user waits for the arrival of the elevator at the landing of the low floor group and boards the elevator car from there.
As shown in fig. 1, the elevator system 3 includes an assigned elevator determination unit 3a and an elevator control unit 3 b. The assigned elevator determining section 3a responds to a call registration request from the elevator display device 2, performs the call registration to the elevator control section 3b, and determines an assigned elevator for the call registration. The elevator control section 3b receives information on the assigned elevator from the assigned elevator determination section 3a, and controls the operation of the elevator car in accordance with the information.
When a user moves to an elevator hall through a door, an elevator display device 2 provided in the safety door system 1 displays information for quickly guiding the user to the elevator hall. As shown in fig. 1, the elevator display device 2 includes a call registration unit 2a, a timer unit 2b, an assigned elevator input unit 2c, a group identification unit 2d, a display command unit 2e, and a display unit 2 f.
The call registration unit 2a receives the user's destination floor information read by the reading unit 1a from the reading unit 1a, and makes a hall call registration request including the destination floor information to the assigned elevator determination unit 3a of the elevator system 3. Further, the call registration section 2a transmits a timing start instruction to the timing section 2b at the time when the hall call registration request is made.
The timing section 2b receives a timing start command from the call registration section 2a, and thereby measures an elapsed time from the time when the call registration section 2a makes a hall call registration request to the assigned elevator deciding section 3a of the elevator system 3. The time point at which the measurement of the elapsed time is started is not limited to this, and may be, for example, the time point at which the reader 1a reads the user's destination floor information.
When the elapsed time measured by the timer unit 2b reaches a predetermined time set in advance, the bank specifying unit 2d specifies the bank corresponding to the floor area to which the destination floor requested by the call registration unit 2a is belonging. The following describes the determination method. The bank specifying unit 2d stores service floor information for each bank in advance. The group identification unit 2d refers to the service floor information for each group and searches for a service floor of which group the destination floor requested by the call registration unit 2a belongs to. In this way, the bank identification unit 2d identifies the bank corresponding to the destination floor by the search. The bank specifying unit 2d transmits bank information indicating the specified bank to the display command unit 2 e.
The information of the assigned car determined by the assigned car determination unit 3a and to be taken by the user is input from the assigned car determination unit 3a to the assigned car input unit 2 c. The assigned car input unit 2c transmits the assigned car information to the display command unit 2 e.
The display command unit 2e determines whether or not the assigned elevator information is input from the elevator system 3 to the assigned elevator input unit 2c before the elapsed time measured by the timer unit 2b reaches a predetermined time. This determination is made based on whether or not the display command unit 2e has received the assigned car information from the assigned car input unit 2 c. That is, if the display command unit 2e receives the assigned elevator information from the assigned elevator input unit 2c within a predetermined time, it is determined that the assigned elevator information is input from the elevator system 3 to the assigned elevator input unit 2 c. On the other hand, if the assigned car information is not received from the assigned car input unit 2c within the predetermined time, the display command unit 2e determines that no assigned car information is input from the elevator system 3 to the assigned car input unit 2 c. When it is determined as a result of the determination that the assigned car information has been input, the display command unit 2e outputs a first command for instructing display of the assigned car information to the display unit 2 f. On the other hand, when it is determined that no car information is input, the display instruction unit 2e outputs a second instruction to the display unit 2f to instruct the display of the bank information transmitted from the bank specifying unit 2 d. Thus, the display information displayed on the display unit 2f is switched to either the assigned car information or the bank information based on the elapsed time measured by the timer unit 2 b. The display instructing unit 2e executes the switching processing for switching the display information in this manner.
The display unit 2f is configured by a display device such as a display, and has a display screen. The assigned car information or the bank information is displayed on the display screen in accordance with the first command or the second command from the display command section 2 e. The display unit 2f is provided in the door of the security gate system 1. When passing through the door, the user observes display information displayed on the display unit 2f provided at the door, and confirms a moving place to which the user should go.
Next, a hardware configuration of the elevator display device according to embodiment 1 will be described. The respective functions of the reading section 1a, call registration section 2a, time counting section 2b, assigned elevator input section 2c, bank specifying section 2d, display instruction section 2e, and display section 2f shown in fig. 1 are realized by a processing circuit. The Processing circuit may be dedicated hardware or may be a CPU (Central Processing Unit) such as a microcomputer. When the processing circuit is a CPU, the respective functions of the reading section 1a, the call registration section 2a, the time counting section 2b, the assigned elevator input section 2c, the bank specifying section 2d, the display instruction section 2e, and the display section 2f are realized by software or firmware. The software or firmware is described as a program and is stored in the memory. The processing circuit reads out and executes the program stored in the memory, thereby realizing the functions of each section.
Next, the operation of the elevator display device according to embodiment 1 will be described with reference to fig. 1 and 2.
Fig. 2 is a flowchart showing the operation of the elevator indicating device according to embodiment 1 of the present invention, and shows a specific processing flow of the elevator indicating device 2.
In the security gate system 1, when a user wants to pass through a gate, user information of the user is read from a user's portable storage medium by a reading unit 1 a. The reading unit 1a extracts destination floor information from the read user information and outputs the destination floor information to the elevator display device 2.
In step S101, the call registration section 2a receives the destination floor information from the reading section 1 a. As described above, the destination floor information is information indicating the destination floor of the user and is stored in advance in the portable storage medium of the user.
Next, in step S102, the call registration section 2a requests the elevator system 3 to register a hall call to a destination floor for a bank corresponding to the user' S destination floor based on the destination floor information received in step S101. Then, the elevator display device 2 waits for a response from the assigned elevator system 3, and moves to step S103.
In step S103, the timing section 2b starts measuring the elapsed time from the time when the call registration section 2a requests the elevator system 3 to register a hall call in accordance with a timing start command from the call registration section 2a, and moves to step S104. In this way, by measuring the elapsed time by the timer unit 2b, the elevator display device 2 can display, at a desired timing, the assigned elevator that the user should take or the group information of the hall that the user should go to the user who has passed the door, based on the measured elapsed time.
Here, the elevator system 3 that has requested the hall call registration executes the hall call registration to the elevator control section 3b by the assigned elevator determination section 3a, and determines an assigned elevator to travel to the destination floor. Then, the assigned elevator determining unit 3a performs transmission processing of information on the determined assigned elevator as a response to the elevator display device 2.
In step S104, the display command unit 2e checks whether or not there is a response from the elevator system 3 to the assigned elevator input unit 2 c.
In step S105, when the display command unit 2e confirms that there is a response from the elevator system 3 to the assigned elevator input unit 2c in step S104, the process proceeds to step S106. On the other hand, if the response is not confirmed, the process proceeds to step S107.
In step S106, the display instruction unit 2e sets the information on the assigned car as the display information to be displayed by the display unit 2f, and moves to step S109.
In step S107, the timer unit 2b determines whether or not the elapsed time measured by the timer unit 2b in step S103 exceeds a predetermined time set in advance. If the result of the determination is over, the timer section 2b sends a signal to the bank determination section 2d, and moves to step S108. On the other hand, if not, the process returns to step S104, and the processes of step S104, step S105, and step S107 are repeated.
In step S108, the bank specifying unit 2d receives the signal from the timer unit 2b, specifies the bank corresponding to the destination floor for which the call registration unit 2a requested the hall call registration in step S102, and transmits the specified bank to the indication instructing unit 2 e. The display instructing unit 2e sets the information on the bank as the display information to be displayed by the display unit 2f, and moves to step S109. Here, the information about the bank set as the display information to be displayed by the display unit 2f is, for example, the name of the bank. In this case, the display section 2f displays, for example, "lower step group", "middle step group", and "upper step group". Alternatively, the names of the landings corresponding to these banks may be display information. Examples of the hall names of the banks include "hall for a low-rise bank", "hall for a middle-rise bank", and "hall for a high-rise bank".
In step S109, the display unit 2f displays the display information set by the display instruction unit 2e in step S106 or step S108 on the screen.
In this way, in step S108, when the information on the bank corresponding to the destination floor is set as the indication information, the indication device constituting the indication portion 2f provided in the door indicates the information on the bank. The user who has passed the door confirms the information on the bank displayed on the display section 2f and moves ahead to the landing corresponding to the bank. The user who arrives at the landing gets on the car that arrives at the landing. Alternatively, after confirming the assigned elevator displayed on a display device different from the display section 2f provided at the hall, the user boards the assigned elevator. Here, the different display devices may be constituted by display devices such as a display or hall lamps provided in a hall. In addition, in the case where the different display device is configured by a display device such as a display, for example, the assigned elevator is displayed together with the user ID information or the assigned elevator is displayed together with the user destination floor information so that the user can determine whether or not the display is directed to the user.
As described above, according to embodiment 1 of the present invention, if there is a response from the elevator system 3 before the elapsed time measured by the timer unit 2b reaches the predetermined time, the display unit 2f displays the assigned elevator. On the other hand, when the elapsed time measured by the timer unit 2b exceeds the predetermined time and there is no response from the assigned elevator of the elevator system 3, the display unit 2f displays the bank information corresponding to the user's destination floor. Therefore, at a point in time when the elapsed time measured by the timer unit 2b exceeds the predetermined time, the display unit 2f always displays any one of the information on the assigned car and the information on the bank. Thus, the user passing through the door can specify the moving place to which the user should move based on the information on the assigned car or the group of stairs, and can move forward to the landing without lowering the walking speed. As a result, it is possible to prevent the occurrence of a jam at the door and to prevent the number of people passing through the door from being reduced, thereby suppressing a reduction in the serviceability of the elevator. As described above, in embodiment 1, the information of the moving place to which the user should go is displayed to the user passing through the door at the optimum timing for management in accordance with the predetermined time, and therefore the user can be smoothly guided to the elevator hall.
Even when the distance from the door of the security gate system 1 to the elevator landing is long, the user can move forward in the direction of the elevator landing without waiting for the determination of the assigned elevator at the time of displaying the bank information, and therefore the user who arrives at the landing can quickly board the car after the car arrives.
The predetermined time used for the determination in step S107 may be appropriately adjusted in consideration of the length of the door of the safety door system 1 and the average moving speed of the user. That is, the time may be set to a range of 1 to 3 seconds or may be set to about 10 seconds.
In embodiment 1, the case where the display information of the display command unit 2e is switched according to the elapsed time measured by the timer unit 2b has been described. In contrast, in embodiment 2, a case will be described in which display information is switched depending on whether or not the elapsed time measured by the timer unit 2b is a congestion state.
For example, in the idle time period, even if the speed of the user passing through the door is slightly slow, the entire elevator running service such as the average waiting time is not hindered. Therefore, in such an idle time period, the user must confirm the assigned car at the door, and the user may be able to take the car by one-time display confirmation, which may reduce the labor of the user.
Fig. 3 is a configuration diagram showing the configuration of an elevator display device according to embodiment 2 of the present invention. A difference from embodiment 1 is that a congestion judging unit 2g is added to the configuration of fig. 1 in fig. 3.
The congestion determination unit 2g determines whether or not the periphery of the door of the emergency gate system 1 or the elevator landing is congested. The door periphery is set to a range of a radius of 5m with the center of the door as a center point, for example, as appropriate. As a determination method of the congestion determination unit 2g, for example, a method of using a sensor such as an infrared camera to perform a result of imaging around a door or at an elevator landing is considered. In this case, the congestion determination unit 2g analyzes the image obtained by the capturing to determine the number of users. Then, when the number of people is equal to or greater than a preset threshold, the congestion judging unit 2g judges that the person is in the congestion state, and when the number of people is less than the threshold, the congestion judging unit 2g judges that the person is not in the congestion state.
Alternatively, the congestion determination unit 2g may obtain information on the number of call registrations from the call registration unit 2a or the assigned elevator determination unit 3a to determine whether or not the call registrations are in a congested state. In this case, the congestion determining unit 2g determines that the call is in a congested state when the number of call registrations is equal to or greater than a predetermined threshold value, and determines that the call registrations are not in a congested state when the number of call registrations is less than the threshold value.
Alternatively, the congestion determination unit 2g may acquire information of a user who has passed through the door from the reading unit 1a or the call registration unit 2a to determine whether or not the door is congested. In this case, the congestion determining unit 2g determines that the user is in the congestion state when the number of users who pass through the gate per unit time is equal to or greater than a preset threshold value, and determines that the user is not in the congestion state when the number of users is less than the threshold value.
Next, a hardware configuration of an elevator display device according to embodiment 2 will be described. In embodiment 2, the functions of the congestion determining unit 2g are realized by a processing circuit together with the functions of the reading unit 1a, the call registration unit 2a, the time counting unit 2b, the assigned elevator input unit 2c, the bank specifying unit 2d, the display instructing unit 2e, and the display unit 2 f. The processing circuit is the same as that described in embodiment 1, and therefore, the description thereof is omitted here.
Next, the operation of the elevator display device 2 according to embodiment 2 will be specifically described with reference to fig. 3 and 4.
Fig. 4 is a flowchart showing the operation of the elevator display device 2 according to embodiment 2 of the present invention, and shows a specific processing flow of the elevator display device 2.
In fig. 4, steps S201 to S205 are the same as the operations in steps S101 to S107 described in embodiment 1, and therefore the description thereof is omitted here.
In step S206, it is determined that the predetermined time has elapsed since the elapse time measured by the timer unit 2b in step S205. Therefore, in step S206, it is determined whether the door periphery or the elevator landing is congested. If it is determined that the state is congested, the process proceeds to step S207. After step S207, the display command unit 2e sets the bank determined by the bank determining unit 2d as display information, and the display unit 2f displays the display information on the screen, in the same manner as after step S108 of embodiment 1.
On the other hand, when it is determined in step S206 that the congestion state is not present, the process returns to step S202, and the process from step S202 to step S206 is repeated. Thus, for example, in an idle time period or the like in which the entire elevator running service such as the average waiting time is not hindered, the user can always confirm the assigned elevator at the door, and therefore the user can recognize the assigned elevator that the user should ride by one-time display confirmation.
In fig. 4, it is described that the determination process of step S206 is performed after the determination process of step S205 is performed, but the order of the processes of step S205 and step S206 is not limited, and therefore step S205 may be performed after the determination process of step S206 is performed.
According to embodiment 2 of the present invention, the congestion determining unit 2g determines whether or not congestion is occurring. When it is determined that the elevator system is congested and there is no response from the assigned elevator of the elevator system 3 within a predetermined time, the display unit 2f displays the bank as display information once, thereby suppressing a decrease in the speed of the user passing through the door. In addition, when the elevator system is uncongested, a response from the assigned elevator of the elevator system 3 is waited, and the assigned elevator is displayed to the user at the door through the display part 2 f. Thus, the user can recognize the assigned car and ride the car by performing display confirmation only once. That is, in the non-congestion state, compared with the case where the display confirmation of the assigned elevator is performed after the display confirmation of the bank, the labor of the user can be reduced within a range not interfering with the elevator operation service.
The configuration diagram showing the configuration of the elevator display device according to embodiment 3 of the present invention is basically the same as that in fig. 3, and therefore, the description thereof is omitted here. The embodiment 3 differs from the above-described embodiment 2 only in the congestion determination operation of the congestion determination unit 2 g. Therefore, the flowchart showing the operation of the elevator indicating device 2 according to embodiment 3 is basically the same as that shown in fig. 4, and therefore the description thereof is omitted here.
In embodiment 2 described above, whether or not congestion is caused is determined based on one threshold value common to all time slots. In contrast, in embodiment 3, as shown in fig. 5, the congestion determination threshold is set for each time slot. In embodiment 3, a case where a plurality of congestion determination threshold values are set will be described with reference to the example of fig. 5. In the example of fig. 5, the threshold value for the number of people passing through the gate per unit time is set as the congestion determination threshold value. In each time slot, when the number of people passing through the gate per unit time is equal to or greater than the congestion determination threshold, the congestion determination unit 2g determines that the state is congested. The unit time is set to, for example, 5 minutes.
In embodiment 3, the congestion determining unit 2g includes a congestion degree determination table shown in fig. 5 in advance. The congestion degree determination table stores congestion determination thresholds that can be set for each time slot. The congestion determining unit 2g receives information of a user who has passed through the door from the reading unit 1a as needed. The congestion determining unit 2g determines the number of users passing through the gate per unit time based on the information of the users. The congestion determining unit 2g has a clock for detecting the current time or receives information of the current time from the outside. Then, the congestion determining unit 2g extracts the congestion determination threshold value for the corresponding time slot from the congestion degree determination table based on the current time. In this way, the congestion determining unit 2g compares the number of people passing through the gate per unit time with the extracted congestion determination threshold, and determines that the state is congested when the number of people is equal to or greater than the congestion determination threshold.
In fig. 5, "'corresponding to 1' indicates an empty time period in which congestion is not expected. In this time zone, since there is no problem even if the speed of the user passing through the door decreases, the function of the congestion judging unit 2g is disabled, and the degree of congestion is not judged.
In fig. 5, "[ 2": 00-10: the working time period of 00 is a time period in which the display information needs to be displayed promptly on the display unit 2 f. In this time period, there are users who pass through the door continuously, and therefore there is a possibility that the following user will misrecognize the display information for the preceding user as the display information of itself. Therefore, in this time period, the congestion determination threshold is set to the minimum value. In the example of fig. 5, 60 persons are assumed.
In fig. 5, "[ 2": 00-13: 17 for lunch period and working day of 00: 00-19: off duty time period of 00. These time periods are less than the work hours described above, but they are expected to be the second crowded time periods. Therefore, in these time zones, it is also necessary to quickly display the display information on the display unit 2 f. Therefore, in these time periods, the congestion determination threshold is set to the second smallest value. In the example of fig. 5, 90 persons are assumed.
According to embodiment 3 of the present invention, when the congestion determination unit 2g determines whether or not the elevator is congested and when there is no response from the assigned elevator in the elevator system 3 within a predetermined time during the congestion, information on the bank is displayed as display information, thereby suppressing a reduction in speed of the user passing through the door. Further, since the user can always confirm the assigned car at the gate when the elevator is not congested, the user can recognize the assigned car and take the car by performing display confirmation only once, and thus, the labor of the user can be reduced as compared with the case where the display confirmation of the assigned car is performed after the display confirmation of the bank is performed. Further, in embodiment 3, since the congestion determination threshold is set for each time slot, the display information can be appropriately switched according to the congestion degree.
In embodiment 3, the congestion determination threshold is set for each time zone, but the present invention is not limited to this case, and the congestion determination threshold may be set for each operation state of the elevator. Further, as an example of the operation state of the elevator, an operation state such as an operation during work, an operation during lunch, and an operation during work can be given.
Embodiment 4.
In embodiments 1 to 3, the case where the correspondence relationship between each bank and the corresponding car is fixed has been described. In recent years, however, depending on the operating conditions or time zones of the elevators, the elevators in a bank are sometimes divided into a plurality of small groups, and each bank and the corresponding elevator are switched as appropriate. As such a specific example, there are cases where: the operation of supporting the crowded adjacent elevator groups or the operation of going to the same destination floor by a plurality of elevator groups with the large-scale building is carried out. In such a case, since the candidate for the bank for the destination floor is 2 or more, the bank specifying unit 2d cannot uniquely specify the bank for the destination floor. Therefore, in embodiment 4, an embodiment will be described which can be handled even when the bank specifying unit 2d cannot uniquely specify a bank.
Fig. 6 is a configuration diagram showing the configuration of an elevator display device according to embodiment 4 of the present invention. A difference from embodiment 2 is that an area determination unit 2h is added to the structure of fig. 3 in fig. 6.
When the bank specifying unit 2d cannot specify a bank for a reason such as a plurality of candidate banks, the area determining unit 2h determines an area to which the user who has passed the gate should go. The determined region is displayed on the screen on the display unit 2f by the display command unit 2 e. Thus, the user can go to a designated area without reducing the speed of passing through the door. Examples of the area determined by the area determination unit 2h include an elevator installation area in a building, an installation location of a display device provided near an elevator hall for displaying assigned elevator information, and the like.
The area determination unit 2h also stores an area determination table in advance. In the area determination table, areas to be traveled next by the user who has passed through the door are defined in advance for each destination floor. The area determination unit 2h extracts an area corresponding to the destination floor from the area determination table based on the destination floor information of each user read by the reading unit 1 a.
Next, a hardware configuration of an elevator display device according to embodiment 4 will be described. In embodiment 4, the functions of the area determination unit 2h are realized by a processing circuit together with the functions of the reading unit 1a, the call registration unit 2a, the time counting unit 2b, the assigned elevator input unit 2c, the bank specifying unit 2d, the display instruction unit 2e, the display unit 2f, and the congestion determination unit 2 g. Since the processing circuit is as described in embodiment 1, the description thereof is omitted here.
Next, the operation of the elevator indicating device 2 according to embodiment 4 will be specifically described with reference to fig. 6 and 7.
Fig. 7 is a flowchart showing the operation of the elevator display device 2 according to embodiment 4 of the present invention, and shows a specific processing flow of the elevator display device 2.
In fig. 7, steps S301 to S306 are the same as the operations in steps S201 to S206 described in embodiment 2, and therefore the description thereof is omitted here.
In step S307, the bank specifying unit 2d determines whether or not there are a plurality of bank candidates corresponding to the user' S destination floor, and when one bank candidate is specified, the process proceeds to step S308, and sets the information of the specified bank as the display information to be displayed on the display unit 2f, and proceeds to step S310, in the same manner as in step S207 of embodiment 2, and in step S310, the display information is displayed on the display unit 2 f.
On the other hand, when it is determined in step S307 that there are a plurality of candidates for the bank, the process proceeds to step S309, the area determination unit 2h determines an area to be traveled next for the user who has passed through the door, sets information on the area as display information to be displayed on the display unit 2f, proceeds to step S310, and displays the information on the area on the display unit 2f in step S310.
According to embodiment 4 of the present invention, even in a case where the elevators in a group are divided into a plurality of small groups according to the operation status of the elevator, and the corresponding elevator group cannot be uniquely identified from the destination floor information of the user, such as a case where the operation of supporting crowded adjacent groups is performed or the operation of multiple elevator groups to the same destination floor is performed along with the large-scale building, the user who has passed through the door can confirm the area to go next without lowering the walking speed, and thus the congestion at the time of passing through the door and the reduction in the number of people passing through the door can be reduced, so that the service degradation of the elevator can be suppressed.
In the above description, the example in which the region determining unit 2h is added to the configuration of fig. 3 is described as shown in fig. 6, but the present invention is not limited to this, and the region determining unit 2h may be added to the configuration of fig. 1.
In embodiments 1 to 4, even for a person who has a low speed of passing through a door, such as a wheelchair user or an elderly person, display information is displayed on the display unit 2f for the same time as a healthy person.
However, as for the wheelchair user, the elderly, and the like, it is assumed that, for example, even if it takes time, it is desirable to display the assigned number at the door from the beginning, as compared with the case where the assigned number is displayed by a different display device after the ladder group is displayed on the display portion 2 f.
Therefore, in embodiment 5, the display information is not switched by the display instruction unit 2e for the user belonging to the specific division. For this reason, in embodiment 5, the call registration part 2a stores a switching application determination table shown in fig. 8 in advance. The switching application determination table defines in advance information on whether or not the switching process based on the display information of the display instruction section 2e is applied, for each attribute of the user who passes through the door. In the example of fig. 8, it is defined that the switching process of the display information is not applied to the wheelchair user, the elderly person, and the visitor, and the switching process of the display information is applied to the other users. In the example of embodiment 5, wheelchair users, elderly people, and visitors belong to a specific division. The elevator display device 2 performs the operation described in embodiment 1 for users other than the specific division. That is, for users other than the specific division, switching of display information by the display instruction unit 2e is performed based on the elapsed time measured by the timer unit 2b as described in embodiment 1.
In fig. 8, "'1' indicates a user who is expected to pass through a door slowly, such as a wheelchair user or an elderly person, and" '2' indicates a visitor, such as a visitor card user, and indicates a user who is considered unfamiliar with the in-building information of the building and has a slightly slow speed of passing through the door, but has a high efficiency of assigning the number machine.
In embodiment 5, first, the reading unit 1a reads user information of a user from a portable storage medium carried by the user who wants to pass through the door. At this time, the reading unit 1a also reads attribute information of the user required for determining the condition of fig. 8, such as age and whether or not the user uses a wheelchair.
The call registration unit 2a receives the user's destination floor information read by the reading unit 1a from the reading unit 1a, and makes a hall call registration request based on the destination floor information to the assigned elevator determination unit 3a of the elevator system 3. At this time, the call registration section 2a also receives attribute information of the user read by the reading section 1a from the reading section 1 a. The call registration section 2a determines whether or not the switching process of the display information by the display instruction section 2e shown in embodiment 1 is applied, based on the attribute information. As a result of the determination, when it is determined that the switching process is applied, the call registration part 2a outputs a timing start command to the timing part 2b to execute the switching process of embodiment 1. On the other hand, when it is determined that the switching process is not applicable, the call registration part 2a does not output a timing start command to the timing part 2 b. Further, the call registration section 2a outputs a command signal to the display command section 2e so as not to execute the switching process of the display information. The display command unit 2e receives the command, waits until the assigned elevator information is input from the elevator system 3 to the assigned elevator input unit 2c, and instructs the display unit 2f to display the assigned elevator information when the assigned elevator information is input.
In embodiment 5, in the switching application determination table of fig. 8, whether or not the process of switching the display information on the display unit 2f from the information of the assigned car to the bank information or the area information is applied is defined in advance for each attribute of the user. Then, even when receiving user information of a person passing through a door such as a destination floor, the call registration section 2a receives attribute information such as age or the presence or absence of use of a wheelchair, and determines whether or not to perform a switching process of display information based on the attribute. Accordingly, the display information switching process may not be performed depending on the attribute of the user, and therefore, the assigned car number can be displayed at the door even if the user takes a little time.
As described above, in embodiment 5, attribute information of the user is input from the reading section 1a to the call registration section 2a together with information of the user's destination floor. The call registration section 2a determines whether or not the attribute information matches a predetermined specific division. When the attribute is determined to correspond to the specific division as a result of the determination, the call registration part 2a waits until the assigned elevator information is input from the elevator system 3 to the assigned elevator input part 2c without switching the display information to the display command part 2e, and instructs the display part 2f to display the assigned elevator information when the assigned elevator information is input.
In the above description, the example in which embodiment 5 is applied to the configuration of embodiment 1 has been described, but the present invention is not limited to this case, and embodiment 5 can be applied to any configuration of embodiments 2 to 4.
