And a second operation mode in which predetermined information is displayed at a second luminance lower than the first luminance, and the group management control system includes, for each floor, a destination floor input device at a departure reference floor. The number of visitors from each floor is counted by counting the number of destination floor registrations by counting the number of visitors on each floor, and counting the number of operations of the destination floor input device on the general floor. Measure, if the number of exits is equal to the number of visitors, the elevator user operating the destination floor input device of the general floor is determined to be the final exit on the floor where the destination floor input device is installed, When the group management control system determines that the elevator user who operates the destination floor input device is the last exit person on the floor where the destination floor input device is installed, after the operation is completed, the operated destination floor input device is operated. The display is set to the second operation mode .
Further, in order to solve the above problems, a group management elevator system according to the present invention is provided in an elevator hall, a destination floor input device for an elevator user to input a destination floor, and an elevator assigned to a destination floor from a plurality of elevators. And a group management control system for selecting a destination floor, the destination floor input device includes a display unit for displaying predetermined information, and the display unit displays the predetermined information at a first luminance. Operation mode, and has a second operation mode of displaying predetermined information at a second luminance lower than the first luminance, the first operation according to the traffic situation determined by the group management control system, One of the operation mode and the second operation mode is set, and the second operation mode is set in a time zone where the installation location of the destination floor input device receives solar radiation.

  Problems, configurations, and effects other than those described above will be apparent from the following description of the embodiments.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings, components having the same reference number indicate the same components or components having similar functions.

  FIG. 1 shows an entire configuration of a group management elevator system according to an embodiment of the present invention.

  As shown in FIG. 1, the group management elevator system according to the present embodiment includes an elevator control system 210, 220, 2n0 for individually controlling a plurality of elevators, and an elevator control system for each elevator so as to optimize the operation efficiency of the entire elevator. And a group management control system 100 for controlling operation. In addition, at or near the elevator hall on the entrance floor (departure reference floor or movement start floor) of the building, destination floor input devices (hereinafter, referred to as “destination floor input devices”) 500 and 510 for the hall are installed. . Each of these destination floor input devices 500 and 510 has destination key input units 501 and 511 of a ten-key system and display units 502 and 512 for displaying destination floor input information and assigned elevators. That is, when the use of the elevator is permitted to a specific elevator user (hereinafter, referred to as “user”) to enhance the security effect (500S, 510S), the personal identification information and the destination stored in the device carried by the user. It has recognition units 503 and 513 that read floor information and perform destination floor registration.

  As a device carried by the user, if it is a tag such as a card, a non-contact IC card or an IC tag equipped with a passive RFID that operates using radio waves from a recognition unit 513 (for example, a card reader) as an energy source ( For example, an ID card) can be applied. In addition, information terminal devices such as mobile phones, smart phones (multifunctional mobile phones), and tablet terminals are also applicable. The communication unit of these devices includes an NFC (Near Field Communication) interface applied to short-range wireless communication with an IC tag, and Bluetooth (registered trademark) or Wi-Fi (registered trademark) capable of communicating a larger amount of information. A wireless communication protocol such as a 3G (3rd Generation) line, LTE (Long Term Evolution), or the like is preferable.

  Destination floor input devices 520 and 5n0 are installed near the elevator halls on each floor. Each of these destination floor input devices 520 and 5n0 has ten-key type input devices 521 and 5n1, and display units 522 and 5n2 for displaying destination floor input information and assigned elevators, respectively, and further enhances the security effect (520S, 520S). 5n0S) includes recognition units 523 and 5n3.

  The input / output main processing device 400 is connected to the destination floor input device, and controls input and output of data between the group management control system 100 and the destination floor input device. When the personal identification information is stored in the ID card, the input / output main processing device 400 includes a personal authentication database in which the personal identification information of the user who is permitted to use the elevator is registered in advance. By comparing the personal identification information read by the recognition unit with the database, it is determined whether or not the user is permitted to use the elevator. At this time, if the destination floor information is registered in the database in correspondence with the personal identification information, the input / output main processing device 400 determines that the user is permitted to use the elevator and responds to the personal identification information. The destination floor information is transmitted to the group management control system 100. Thereby, the destination floor is automatically registered for each individual while ensuring security. Alternatively, if the input / output main processing device 400 determines that the user is permitted to use the elevator, the input / output main processing device 400 permits the input of destination floor information using the numeric keypad of the destination floor input device. Then, the destination floor information input from the destination floor input device is sent from the input / output main processing device 400 to the group management control system 100 and registered. In this case, the size of the personal authentication database can be reduced as compared with the case where the destination floor is automatically registered.

  If the ID card stores card information indicating that the card is a legitimate card given to a person who is permitted to use the elevator, the input / output main processing device 400 reads the card information by the recognition unit of the destination floor input device. Based on the received card information, it is determined whether or not the card is a legitimate card. If it is determined that the card is a legitimate card, input of the destination floor information using the numeric keypad of the destination floor input device is permitted. Then, the destination floor information input from the destination floor input device is sent from the input / output main processing device 400 to the group management control system and registered. Thereby, security is ensured. In this case, the ID card functions as a so-called operation permission card (entry permit or the like). Therefore, the load on the input / output main processing device 400 in the personal authentication process is reduced, and the configuration of the input / output main processing device 400 can be simplified because a large-scale personal authentication database is not required.

  FIG. 1 also shows a detailed configuration diagram of the elevator control system 210. In FIG. 1, for convenience, this configuration diagram is shown overlapping control lines B1 and B2 between the elevator control system and the elevator. However, although the control lines B1 and B2 are illustrated as being interrupted, they are continuous like the control line B3.

  The elevator control systems 210, 220, and 2n0 operate under control of the operation management control system 101 in the group management control system 100, and operate under an operation control system 212 that performs an operation suitable for an elevator operation method such as automatic operation or manual operation. The operation of each elevator is individually controlled by a speed control system 213 that mainly performs motor control for raising and lowering the cars 310C, 320C, and 3n0C. Further, the elevator control system transmits information on each event such as the load in the car and the opening and closing of the door to the operation management control system 101 of the group management control system 100 for each elevator. During the group management operation, the operation management control system 211 in the elevator control system does not operate. In addition, the elevator control system, when the destination floor information is input and registered by the destination floor input device before the elevator boarding, the destination provided in the operation panel 311, 321, 3n1 in the car during normal operation Invalidates floor button input.

  In the group management control system 100, the operation management control system 101 transmits operation data such as elevator information and destination floor information transmitted from the elevator control system that changes from moment to moment to the learning system 102. Based on the transmitted operation data, the learning system 102 learns the traffic conditions and determines what driving program is appropriate at that time based on the traffic conditions already learned and the current operation data. I do. The intelligent system 103 newly generates a feature mode described later based on the learning result of the learning system 102, performs an elevator operation simulation, and automatically generates an optimal driving program according to each feature mode. Using this operation program, the operation management control system 101 executes allocation control for deciding which elevator is to be allocated for each registered destination floor, and sends an allocation command for each destination floor to the elevator control system.

  In the case where the group management control is canceled and the isolated operation is performed, the operation of the elevator is controlled by the operation management control system 211 in the elevator control system. At this time, the input / output main processing device 400 controls input / output of data between the operation management control system 211 and the hall destination floor registration device.

  FIG. 2 is a functional block diagram of the learning system 102 in the group management control system 100. The learning system 102 learns / determines from the traffic demands of each floor, such as the state of low traffic of the elevator and the time zone during which the number of people getting on and off at night is small.

  As shown in FIG. 2, the in-car getting on and off person detecting unit 202 detects the number of getting on and off the person based on the output signal of the load detecting device installed under the car floor. Here, the in-car getting on / off person detecting unit 202 detects the number of getting on / off the person from the load change in the car until the car arrives and departs. The traffic status (traffic information) collection unit 201 calculates the number of passengers getting on and off the car detected by the in-car getting on / off detection unit 202 for each floor and unit of direction (up and down) per unit time as exemplified in the block. Collect as information. At this time, the traffic condition (traffic information) collection unit 201 collects traffic information for each floor, using the destination floor information 203 registered in the group management control system as appropriate.

  The number of passengers in / out of the car detecting unit 202 detects the number of passengers in or out of the car based on the number of hall calls (the number of operations of the destination floor input device) and the number of car calls (the number of destination floor registrations). The number of people getting on and off the vehicle may be detected based on the information.

  The flow of people in a building varies with floor and direction, and generally has a complex distribution. Therefore, the feature mode identifying unit 204 determines that the traffic information of each floor per unit time collected by the traffic condition (traffic information) collecting unit 201 belongs to any of a plurality of feature modes indicating the status of elevator demand in the building. Identify. Further, the feature mode identification unit 204 calculates an average of collected traffic information for each feature mode on a daily basis, and stores the average in the group management control system based on the calculation result and the calculation result of the previous day. The traffic information data serving as a reference indicating each characteristic mode is updated. The traffic information mode learning unit 205 learns and accumulates the traffic information data updated by the feature mode identification unit 204 as a traffic information mode for each feature mode (M1, M2, M3,...).

  In the present embodiment, the feature modes (M1 to M6) are identified by the range of the number of people getting on and off the car in the up direction and the number of people getting on and off the car in the down direction. Such feature mode identification data is stored in the feature mode generation unit 206. The above-described feature mode identification unit 204 compares the traffic information per unit time collected by the traffic condition (traffic information) collection unit 201 with the feature mode identification data stored in the feature mode generation unit 206, thereby providing traffic information. Identify the feature mode to which the information belongs.

  In FIG. 2, an example of feature mode identification data is shown in a block of the feature mode generation unit 206. The feature modes M1 to M6 in the present embodiment correspond to six areas having different traffic demand conditions on coordinates where the vertical axis and the horizontal axis are the number of people getting on and off the vehicle and the number of people getting on and off the road. The feature modes M1, M2, M3, and M6 are “quiet”, in which the number of people getting on and off is small, “normal”, in which the number of people getting on and off is relatively larger than in M1, “up peak”, in which the number of people getting on and off is large, It is a "down peak" with a large number of passengers. In the traffic demand situation where the number of people getting on and off the vehicle is smaller than the peak but both are relatively large, the characteristic mode in which the number of people going up and down is M4, and the characteristic mode in which the number of people going down is M5.

  In addition, the traffic demand situation of an elevator can change by the change of the tenant who enters a building, etc. Therefore, the feature mode generation unit 206 learns the tendency of the change in the traffic demand situation corresponding to the feature modes M1 to M6 based on the traffic information mode data accumulated in the traffic information mode learning unit 205, and generates a learning result. It has a function of correcting feature mode identification data based on the data. Further, the feature mode generation unit has a function of extracting a new feature of the traffic demand situation, generating and registering a feature mode (Mn).

  Next, the operation of the destination floor input device will be described. As described below, in the present embodiment, the destination floor input device operates the display unit such as the liquid crystal display in the energy saving lighting mode when the feature mode is M1, that is, “quiet”. Thereby, the power consumption of the group management elevator system can be reduced without lowering the service to the user.

  FIG. 3 is a basic flowchart of the control processing for the destination floor input device in the present embodiment.

  Before transmitting operation information or general information from the group management control system or the elevator control systems 210, 220, 2n0 to the destination floor input device via the input / output main processing device 400, the operation management control system of the group management control system 100 Reference numeral 101 denotes whether or not the condition of the energy saving mode is satisfied with reference to the reference characteristic mode-specific traffic information data stored in the traffic information mode learning unit 105 (FIG. 2) of the learning system 102. (Step S301). This condition is a time zone in which the feature mode of the traffic demand situation is M1, that is, “quiet”.

  When it is determined that the condition is not satisfied (S301, NO), that is, when it is not in the idle state, the operation management control system 101 sends the input / output main processing device 400 to all the destination floor input devices installed on each floor. A display command in the normal lighting display mode is transmitted via (step S302). If it is determined that the condition is satisfied (YES in S301), that is, if the vehicle is in a quiet state, the operation management control system 101 sends an energy-saving lighting mode (for example, setting the brightness to a lower level) to all the destination floor input devices on each floor. The display command for (down one step) is similarly transmitted (step S303).

  In the present embodiment, the control shown in FIG. 3 is executed for each floor. When the feature mode is set for the entire building, the same display command is transmitted to all the destination floor input devices installed on all floors. In addition, only the entrance floor may be always in the normal mode as a non-control object for the convenience of the customer.

  FIG. 4 shows a display example in each operation mode (normal mode, energy saving mode) of the destination floor input device. In this display example, the power consumption is reduced by changing the luminance (or luminous intensity) of the display unit constituted by the liquid crystal touch panel display with the backlight. Note that a plasma display or an organic EL display whose brightness can be controlled may be used as the display portion.

  As shown in FIG. 4, the destination floor input device 510 </ b> S controls the backlight in the normal mode (a), that is, when a display instruction in the normal lighting display mode is received, thereby controlling the display unit. The luminance of 512 is set to a standard luminance, for example, about 400 candela (international unit system (SI)). As a result, desired information can be clearly displayed for many users. Therefore, since the user can easily confirm the information, the destination floor can be input quickly. For this reason, many users can efficiently register the destination floor. In addition, when displaying general information other than the operation information (for example, tenant information and weather information), the user can easily confirm the information, so that the information can be notified to many users.

  Further, in the case of the energy saving mode 1 (b), that is, when the display command in the energy saving lighting mode is received, the destination floor input device 510S controls the backlight to reduce the brightness of the display unit 512 to the normal level. It is set lower than the mode (a), for example, about 200 candela which is about 50% of 400 candela in the normal mode. Thereby, the power consumption of the destination floor input device 510S is lower than in the normal mode.

  Further, at the time of the predetermined operation of the destination floor input device, for example, when the energy-saving mode 1 (b) continues for a predetermined time, that is, when the demand for elevators continues for a predetermined time or more, the destination floor input device 510S shown in FIG. As in the energy saving mode (c), the luminance of the display unit 512 is set to a value lower than that of the energy saving mode 1, for example, about 100 candela, which is about 25% of 400 candela in the normal mode. Thereby, the power consumption of the destination floor input device 510S is further reduced as compared with the energy saving mode 1.

  The value of the brightness of the display unit 512 in the energy saving modes 1 and 2 is set to a value that allows the user who registers the destination floor to sufficiently confirm the displayed information when operating the destination floor input device. .

  According to the display in the energy saving lighting mode, information on the operation of the destination floor input device is displayed to a small number of users who register the destination floor, for example, "Hold the card under the screen" shown in FIG. The power consumption of the destination floor input device can be reduced while reliably informing such information and elevator operation information. Thereby, the life of the destination floor input device is improved. If the brightness is set such that the power consumption in the energy-saving lighting mode is lower than the rated power consumption, the service life of the destination floor input device can be extended more effectively.

  FIG. 5 shows an example of the transition of the operation state of the destination floor input device during off hours. In the figure, the operation state changes in the order of (a), (b), (c), (d), (e), and (f). As described with reference to FIG. 3, the display command in the energy saving lighting mode is transmitted from the group management control system to the destination floor input device. Therefore, FIG. 5 shows the operation of the destination floor input device in which the destination floor input operation is performed, and the other destination floor input devices which are installed on the same floor but are not subjected to the input operation are in the standby state in the energy saving lighting mode. ((A) in FIG. 5) is maintained.

  In the operation state (a), the destination floor input device 510S is in a standby state, and the luminosity (brightness) of the display unit is the lowest mode among the normal mode, the energy saving mode 1 and the energy saving mode 2 (FIG. 4). It is set to 2.

  In the operating state (b), when the user holds the ID card over the recognizing unit 513 in accordance with the information displayed on the display unit 512 in the operating state (a), the destination floor input device 510S temporarily sets the brightness of the display unit 512. Set to normal mode. Thus, the user can easily operate the destination floor input device 510S. At this time, when radio waves are radiated from the recognition unit 513 to the ID card, power is supplied to the ID card by the radio waves. With this power, the IC tag included in the ID card operates, and the card information stored in the IC tag is placed on the reflected wave from the ID card.

  Based on the card information placed on the reflected wave received by the recognition unit 513, whether the user is a legitimate user who is permitted to use the elevator, or whether the ID card is It is determined whether or not the card is a legitimate ID card given to the authorized person. Then, when it is determined that the card is a legitimate user or a legitimate card, the state shifts to the operation state (c), and the destination floor input operation becomes possible.

  In the operation state (c), the display on the display unit 512 indicates that the user can perform a destination floor input operation, and prompts the user to input a destination floor, in order to prompt the destination floor registration operation. Instead of a message. When the user presses the numeric keypad according to the message and inputs the destination floor, here "5", the operation state is shifted to the operation state (d).

  In the operation state (d), the destination floor (here, “5”) input by the user is displayed on the display unit. Thereby, the user can confirm whether the input is correct or not. If the ten-key input is delayed for a predetermined time, it is determined that the destination floor input is completed, and the input destination floor information is transmitted to the group management control system 100 and registered. The group management control system 100 allocates an optimal elevator to the registered destination floor. Then, the group management control system 100 instructs the elevator control system of the assigned elevator to dispatch a car to the floor where the destination floor input device in which the destination floor is input is installed.

  In the operation state (e), the elevator number or the name (here, “Lift 1”) of the elevator assigned by the group management control system is displayed on the display unit 512. Thereby, the user can confirm the elevator to be boarded. After a predetermined time, the state shifts to the operation state (f).

  The operation state (f) is the same as the operation state (b). Therefore, the brightness of the display unit 512 is set to the normal mode. Thus, when another user subsequently registers the destination floor, the display unit can be easily checked.

  In the operation state (f), when the destination floor input device 510S is not operated for a predetermined time and the idle state is continued, that is, the time zone in which the idle state is still in an idle state. When the display command in the mode is not transmitted, the operation state of the destination floor input device 510S may return to the operation state (a). That is, the brightness of the display unit 512 may return to the energy saving mode 2 (FIG. 3). Thereby, power consumption can be reduced.

  As shown in FIG. 5, by changing the operation state of the destination floor input device in the off-state, the power consumption of the destination floor input device can be reduced while ensuring convenience for a small number of users. In addition, since the display time in the normal mode having a high luminance is reduced, the life of the display unit is improved.

  In the case where destination floor information is included in the card information and the destination floor is automatically registered, (a), (b), (b), (c) (manual destination floor input by ten keys) in FIG. The operation state changes in the order of d), (e), and (f). Further, upon receiving the reflected wave from the ID card or authenticating the card or the user, the destination floor input device 510S determines that the idle state has been resolved on the floor provided with the destination floor input device 510S. After the determination, the luminous intensity (luminance) of the display unit 512 may be set to the normal mode, and thereafter, the luminance may be maintained in the normal mode.

  FIG. 6 shows an example of the transition of the operation state of the destination floor input device during a quiet time. Note that points different from the example of FIG. 5 will be described.

  In the example of FIG. 6, after the operation state (b), the brightness of the display unit 512 is set to the energy saving mode 1 (FIG. 4) unlike the example of FIG. Also in this example, in a quiet state, the power consumption of the destination floor input device can be reduced while ensuring convenience for a small number of users. In addition, since the display time in the normal mode having a high luminance is reduced, the life of the display unit is improved.

  In the examples of FIGS. 5 and 6, in the off-state, when the operation for destination floor registration is performed on the destination floor input device, the brightness of the display unit is changed to be higher than in the standby state. Based on the above-mentioned traffic demand data for each floor, a predetermined operation on the destination floor input device and an output signal of the load detection device under the car floor, for each floor, the idle state is temporarily relaxed or eliminated. If it is determined that the brightness is present, the brightness of the display unit may be changed. Alternatively, one of the examples in FIGS. 5 and 6 may be selected for each floor.

  Next, a detailed control process for the destination floor input device will be described.

  FIG. 7 is a flowchart illustrating a brightness setting control process for the display unit of the destination floor input device according to the present embodiment.

  First, in step S701, in order to sequentially execute the luminance setting process for all the destination floor input devices, the number n of the destination floor input devices 500 to 5n0 and 500S to 5n0S, that is, the setting of the number of floors n of the building, Initialization processing such as setting relating to the necessity of applying the energy saving mode to each floor is executed.

  Next, in step S702, with respect to the first destination floor input device, it is determined whether or not the destination floor input device is installed on a floor to which the display brightness is reduced, that is, the energy saving mode is applied. If it is determined that the destination floor input device is not installed on the floor to which the mode for lowering display brightness is applied (S702, NO), step S706 is executed. In step S706, the display unit is instructed to perform display in the normal mode having the highest luminance. If it is determined that the destination floor input device is installed on the floor to which the mode for reducing display brightness is applied (S702, YES), step S703 is executed.

  In step S703, it is determined whether a condition for lowering the luminance is satisfied. Such a condition is, for example, a time zone in which the traffic demand feature mode is M1 or M2, that is, a time zone in which the traffic demand is in a state other than the congested state. In the present embodiment, the condition also includes that the elevator hall receives solar radiation from the outside and the area around the destination floor input device is in a bright time zone. When it is determined that the condition for lowering the luminance is not satisfied (S703, NO), step S704 is executed.

  In step S704, it is determined whether the floor on which the destination floor input device is installed is a nonstop floor. When it is determined that the floor is the non-stop floor (S704, YES), step S705 is executed. In this step S705, the energy saving mode 2 (FIG. 4) with the lowest brightness of the display unit is set, and guidance for using other elevating means such as an escalator and stairs is displayed. When it is determined that the floor is not the non-stop floor (S704, NO), the above-described step S706 is executed.

  If it is determined in step S703 that the condition for lowering the luminance is satisfied (S703, YES), then step S707 is executed.

  In step S707, it is determined whether the floor where the destination floor input device is installed is a non-stop floor. When it is determined that the floor is the non-stop floor (S707, YES), step S708 is executed. In this step S708, it is determined whether or not the destination floor input device has been operated. When it is determined that the destination floor input device has been operated (S708, YES), the above-described step S705 is executed. If it is determined that the destination floor input device has not been operated (S708, NO), step S709 is executed. Further, when it is determined in step S707 that the floor is not a non-stop floor (S707, NO), step S709 is also executed.

  In step S709, it is determined whether or not the destination floor input device has not been operated for a predetermined time or more, for example, one minute or more. If it is determined that the operation has not been continued (S709, NO), step S710 is executed.

  In step S710, it is determined whether the condition of the mode for lowering the brightness is a time zone around the destination floor input device in a bright time zone. When it is determined that the surroundings are in a bright time zone (S710, YES), step S711 is executed. In step S711, the display unit is instructed to display in the energy saving mode 2 (FIG. 4) with the lowest luminance. If it is determined that the surroundings are not during the bright time zone (S710, NO), step S712 is executed. In step S712, the display unit is instructed to display the image in the energy saving mode 1 (FIG. 4) in which the luminance is lowered by one step from the normal mode.

  If it is determined in step S709 that the destination floor input device has not been operated for one minute or more (S709, YES), step S713 is executed.

  In step S713, display in the energy saving mode 2 (FIG. 4) with the lowest luminance is commanded on the display unit in response to a situation in which the elevator has not been operated for a predetermined time or more due to the idle state.

  When any of steps S705, S706, S711, S712, and S713 for setting the luminance is executed, step S714 is executed next. In step S714, it is determined whether or not the above-described brightness setting process has been completed for all the destination floor input devices. If it is determined that the processing has not been completed (S714, NO), the process returns to step S702, and the processing after step S702 is repeatedly executed.

  Thus, for each floor where the destination floor input device is installed, if there are no or few users of the elevator on that floor, the display in the energy saving mode can be performed. In addition, the brightness of the display unit can be set according to the floor condition (congestion, brightness, non-stop floor). Therefore, the power consumption of the destination floor input device can be reduced without lowering the service to the user.

  FIG. 8 is a flowchart showing a control process for the destination floor input device with improved security.

  First, in step S801, the group management control system determines whether the operated destination floor input device is a destination floor input device installed on a departure reference floor (for example, an entrance floor or a lobby floor). . This makes it possible to determine whether or not there is a visitor to the building. When it is determined that the operated destination floor device is the destination floor input device of the departure reference floor (S801, YES), step S802 is executed.

  In step S802, the operation of the destination floor input device of the departure reference floor is validated, and the value of the number of visitors recorded in the operation management control system 101 (FIG. 1) of the group management control system is increased by one. After execution of step S802, the process ends.

  When it is determined that the operated destination floor input device is not the destination floor input device of the departure reference floor (S801, NO), step S803 is executed. At this time, the operated destination floor input device is installed on a general floor other than the departure reference floor, and the user who operates the destination floor input device is a leaving person from the general floor.

  In step S803, it is determined whether the user who operated the destination floor input device is the last exit from the general floor. Such a determination is made by the group management control system, for example, by the following means. First, by counting the number of destination floor registrations on the departure reference floor for each floor, the number of visitors on each floor is counted, and the number of exits from each floor by counting the number of operations on the destination floor input device on the general floor. Count the number. If the number of exits is equal to the number of visitors, it is determined that the final exit has been reached. Therefore, the last exited person includes not only the last exited person after working hours but also the exited person when the number of residual persons on the same floor becomes zero.

  The final exit can be determined by recording a history of entry and exit for each user based on personal identification information recorded on an ID card or the like and read by the recognition unit of the destination floor input device. . Note that such a history may be created by the group management control system in the present embodiment, or may be created by another general personal authentication system.

  If it is determined in step S803 that the person is the last exiting player (S803, YES), step S804 is executed.

  In step S804, after the user gets into the car and closes the door, the brightness of the display unit of the operated destination floor input device is changed from the brightness during operation (normal mode or energy saving mode 1 (FIG. 4)). The mode is changed to the energy saving mode 2 (FIG. 4) having the lowest luminance, and the subsequent operations are invalidated. At this time, it is considered that the operation performed after the operation by the final exiting person is not the operation by the authorized user. After execution of step S804, the process ends.

  If it is determined in step S803 that the user is not the final exiting party (S803, NO), step S805 is executed. Here, if it is not the last exiting person, if it is not the last exiting person but it is an exiting person (the number of exiting persons <the number of visitors), the destination floor registration device of the general floor is operated after the last exiting person. Although the case (the number of exits> the number of visitors) is included, it is assumed that the latter case is shown in FIG. Specifically, when a manager or security guard enters the general floor from the emergency stairs for maintenance and inspection of the building on the general floor, or during maintenance of the destination floor input device installed on the departure standard floor And so on.

  In this case, steps S803 and S804 have already been executed, and the input operation of the destination floor input device has been invalidated. Therefore, in step S805, it is determined whether a predetermined encryption operation has been performed on the destination floor input device of the general floor. Here, the predetermined encryption operation includes, for example, simultaneous pressing of two different buttons on the touch panel with different numeric keys, continuous input of two different symbol buttons (for example, “*” and “−”) on the touch panel, and And the operation of an information transmitter such as a smartphone.

  If it is determined in step S805 that the predetermined encryption operation has not been performed (S805, NO), the process ends without canceling the operation invalid state of the destination floor input device. If it is determined that a predetermined encryption operation has been performed (S805, YES), step S806 is executed.

  In step S806, the invalid state of the operation of the destination floor input device is temporarily released until the user gets on the car and the door is closed, and the brightness of the display unit is changed from the energy saving mode 2 to the energy saving mode 1 Is changed to

  By the processing operation shown in FIG. 8, the power consumption of the destination floor input device can be reduced while ensuring security.

  In the processing operation of FIG. 8, the operation of the destination floor input device on the general floor after the final exit has left is invalidated. However, the present invention is not limited to this, and a predetermined operation may be invalidated to ensure security. good. For example, at a predetermined time when there are visitors but there are no exits, such as on the day of the work and two hours before the work time, the operation of the destination floor input device on the general floor other than the departure reference floor is invalidated. Is also good.

  Note that the present invention is not limited to the above-described embodiment, but includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described above. Further, for a part of the configuration of each embodiment, it is possible to add, delete, or replace another configuration.

  For example, the above embodiment can be applied to a case where a plurality of departure reference floors (entrance floors) are provided.

  Further, the energy saving modes 2 and 1 may be set for the feature modes M1 and M2, respectively. Further, when shifting from the feature mode M2 to the feature mode M1, the energy saving mode 1 may be changed to the energy saving mode 2.

  Alternatively, the energy saving mode 1 may be set first, and thereafter, when the destination floor input device is not operated for a predetermined time, the mode may be changed to the energy saving mode 2.
