Description

  The present invention relates to a group management elevator control system.

  Generally, in an office building or the like where tenants are occupying, a plurality of elevators are provided in parallel in an elevator hall. However, since the elevator hall is crowded at times such as when going to and from work or during lunch, for example, a congested floor such as the lobby floor (entrance floor) is set as a common floor, and all elevators are automatically set during the predetermined time period. The operation mode is called back to the common floor.

  In addition, during normal operation, all elevators serve all floors, while during congestion, upper floor service groups that serve only the lobby and upper floors, and lower floors that serve lower floors instead of upper floors. A method is disclosed in which traffic demand concentrated on a specific floor is determined and the transportation capacity is improved by grouping into service groups and performing divided express operations (see Patent Document 1).

  On the other hand, in office buildings where visitors are specified, there is an example in which a time difference is provided in the time of going to and from work and cafeteria hours in units of companies and departments (by floor) to reduce congestion.

JP-A-9-309672

  However, the traffic demand in such buildings constantly fluctuates. Therefore, congestion cannot be reduced in a short time unless the elevator operation mode is efficiently controlled in accordance with fluctuations in traffic demand.

  In Patent Document 1, an operation mode is adopted in which a plurality of elevators arranged in parallel are grouped and different service areas (stop levels) are set, but there is no specific means for detecting the number of elevator users, and the users Control of transportation capacity according to the number has not been studied. For this reason, control of the elevator operation mode is not in time for fluctuations in traffic demand, for example, sudden congestion, and it may take a long time to eliminate the congestion.

  This invention makes it a subject to provide the group management elevator control system which can optimize the operation form of an elevator according to the increase in the traffic demand of the elevator user in a building, and can eliminate congestion early.

  In order to solve the above problems, the present invention is provided in a plurality of elevators, group management control means for controlling operation of the plurality of elevators, and a passage leading to an elevator hall of the plurality of elevators, and the elevator per unit time. User measuring means for collecting information on the number of people passing by or the number of people by destination floor, and the group management control means controls the operation mode of the elevator based on the information collected by the user measuring means It is characterized by.

  Thus, for example, in a congested floor such as a lobby, a gate through which a user passes is installed in a passage that leads to an elevator hall, and information on the number of people passing the user per unit time is collected. Change in traffic demand. And according to the control process defined according to the extent of the change, it can eliminate congestion early by switching to the optimal operation mode of an elevator. Further, by collecting information on the number of users per unit time per unit time, a more optimal operation mode can be provided.

  In addition, a plurality of elevator groups provided in each of the plurality of elevator halls, group management control means for controlling the operation of the plurality of elevators constituting these elevator groups, and at least one common floor It is provided in the passage leading to the hall, and has a user measuring means for collecting information on the number of passengers passing through the elevator group per unit time or the number of people by destination floor, and the group management control means is collected by the user measuring means You may make it control the operation form of an elevator group collectively based on the done information. Here, the common floor indicates a crowded floor such as a lobby floor or a restaurant floor.

  In this case, the user measuring means includes recording means for recording the information corresponding to the time, and the group management control means predictively controls the operation mode based on the information recorded in the recording means. May be. According to this, since the operation mode of the elevator can be predicted based on the recorded information and set in advance, for example, by using it in combination with the gate passing information of the user, It is possible to accurately select the driving mode and reduce congestion at an early stage.

  Furthermore, it is preferable to provide a notifying means for notifying the operation mode for each elevator group from the installation position of the user measuring means to the branching point toward the plurality of elevator halls. According to this, when different operation modes are implemented for each elevator group, the user can grasp the elevator group that services the destination floor in the shortest time, which is effective in preventing congestion. Moreover, it is preferable to provide the elevator hall with notification means for notifying the operation mode for each elevator.

  In addition, the user measuring unit may collect information by transmitting and receiving to / from a wireless IC chip carried by the user. According to this, for example, by recording the user's destination floor information on the chip, it is possible to collect the number of people information by destination floor just by passing through the gate, saving the effort of personal recognition, and a large amount. This is especially effective for scale facilities.

  ADVANTAGE OF THE INVENTION According to this invention, the operation mode of an elevator can be optimized according to the increase in the traffic demand of the elevator user in a building, and the group management elevator control system which can eliminate congestion early can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a sketch showing an elevator arrangement on a lobby floor of a building A to which a group management elevator control system according to the present invention is applied. FIG. 2 is a floor plan of the building A other than the lobby floor. The building A is apparently composed of two structures (cores) as an integral building, but is not limited to this configuration.

  A building A shown in FIG. 1 is composed of an east core 1 (left-side building) and a west core 2 (right-side building), and can be reached via a passageway 3. A gate 4 is installed at one end of the east core 1 at a position to be an entrance of the elevator hall. For this reason, for example, when a visitor who has entered the lobby floor from the outside uses the elevators A8 to A14 of the west core 2, passes through the gate 4 and enters the elevator hall of the east core 1, and then continues through the corridor 3 to the west. It is necessary to escape to the elevator hall of the core 2.

  As shown in FIG. 2, in the other floors, zones 23 and 24 are formed in the east core 1 and the west core 2, respectively, and gates 21 and 22 are formed between each zone and the elevator. .

  In the east core 1 and the west core 2, seven elevators A1 to A7 and A8 to A14 are arranged in parallel, and a total of 14 elevators A1 to A14, which are group-managed, are arranged in two locations. . The elevators A1 to A7 and A8 to A14 basically perform all services for the 19th floor. Company A's tenant occupies the 6th, 16th and 17th floors of East Core 1 of Building A, and Company B's tenant occupies the 8th, 16th and 17th floors of West Core 2.

  Next, in the building A configured as described above, the operation until the elevator user (hereinafter abbreviated as “user” as appropriate) is summed up to create an elevator operation plan will be described with reference to the drawings. . FIG. 3 is a flowchart from when the sensor detects entry into the elevator operation plan.

  First, in step 51, a sensor installed in the gate 4 reads ID information of an elevator user who passes through the gate 4. Next, in step 52, the number of visitors per destination floor is counted from the information read in step 51. Next, in step 53, the number of people in the building A is recognized. Specifically, the current number of people in the room is recognized by taking the difference from the number of people counted in step 52 with the time of 0 visitors (for example, midnight) as the reference time. In step 54, an elevator operation plan is created based on the result.

  Of these processes, Step 51 to Step 53 are installed for the purpose of interlocking with, for example, a building or side security system, an air conditioning / ventilation power automatic adjustment system, and the like. The group management elevator control system can be shared as an increase notice information.

  Next, the operation of collecting visitor information at the gate will be described in detail. Here, as shown in FIG. 1, a lobby floor that is a congested floor is assumed to be a common floor, and the operation of collecting visitor information on this common floor will be described. However, similarly to FIG. By providing the gate, it is possible to collect the traffic demand of the user as a whole building more accurately.

  The gate 4 is configured to recognize the identification number of the visitor who has passed the gate 4 and preferably the attribute information in addition to the identification number for each unit time (for example, 1 minute). create. Then, based on the created visitor information, a mode of operation is appropriately selected at the time of going to and from work and lunch, and at the time of an event for an outsider, and group management elevator control is performed.

  Here, since the movement of visitors is likely to be repeated in the same way every day, at least the gate position (including information that can determine the floor) and date / time information are associated with the usage information data bank as the visitor information. Try to record. In other words, the visitor information is stored for a predetermined period of one day or more, the online information is analyzed based on the information, the future prediction information is estimated, and the online usage is complemented. In this way, based on the visitor information created in consideration of past trends, it is possible to select a more optimal operation form at an early stage by predicting and controlling the operation form corresponding to the time of congestion. Early resolution is possible. In addition, past data can be used for up to three years, and it will automatically follow changes in the building environment and changes in tenants, etc., or more emphasis on the latest data, and future usage trends Can also be requested.

  In addition to the personal number and the entrance gate information, it is preferable that affiliation information capable of estimating the destination floor is recorded as attribute information. Thereby, the number of people for each destination floor can be accumulated, and the optimum elevator operation mode can be selected according to the distribution for each destination floor. In addition, by collecting personal information at the entrance of the cafeteria floor, each floor, or each zone, you can learn the movement information between rooms by daily personal number without receiving personal belonging information. By doing so, it is possible to analyze and estimate the future elevator use floor from the time zone.

  As a personal recognition method using a sensor at the gate 4, recognition means such as fingerprints, voices, and veins of fingers are known, but the most notable is for a micro wireless tag with a built-in antenna called "muchip" There is an IC. It is a very small 0.4mm square, and by simply pasting it on a uniform or identification card, information can be sent to and received from the sensor, enabling easy personal recognition. If this is used, it is not necessary to carry an IC card or the like, and it is not necessary to carry out personal recognition by fingerprint collation, voice recognition, numeric keypad, etc., and is particularly effective in a large-scale facility where a large number of people come and go.

  Next, the operation mode of an elevator is demonstrated in detail. The group management control means of the present embodiment includes, for example, means for setting different service areas for the plurality of elevators A1 to A14, and means for attracting elevators to hall calls generated on the common floor by the plurality of elevators. And a means for automatically calling up elevators having a specific service area regardless of the presence or absence of a hall call on the lobby floor and a common floor with many users. With this configuration, all elevators A1 to 14 Control the mode of operation. Then, the transportation capacity is controlled by switching to the optimum operation mode based on the visitor information during the congestion, compared to the normal operation mode.

  Specifically, as a first means of increasing the transport capacity, a dedicated service that temporarily separates from the group management service for the landing call in the normal operation mode, and services only a single floor or a common floor such as a specific floor and a lobby floor. Carry out driving.

  As a second means, the service floor is divided into upper floors and lower floors, and divided express operation or flexible operation (express group operation) is performed to identify the elevators responsible for each. Here, flexible operation means that when a crowded floor is detected, a large number of users are dispersed and waited for each destination floor, and the appropriate driving method and the number of vehicles dispatched are determined according to the congestion situation such as divided express operation and direct operation. The group management operation control is carried out.

  Further, in a large building having a large floor area, it is necessary to install nine or more elevators, and it may be necessary to shorten the horizontal movement time. That is, there may be a case where a plurality of banks (one unit elevator group in which a plurality of elevators are arranged side by side) are distributed on the same floor, or a transfer elevator that is selectively incorporated into a plurality of banks is provided. In such a building, as a third means, according to the overall congestion situation and the characteristics of the crowded floors, the operation of limiting the number of floors and dividing / separating the number of incorporations is performed on a bank basis. Thereby, the service as a whole can be improved with good balance.

  As a fourth means, a gate is installed for each section (room or tenant) in the in-house management zone (for example, zones 23 and 24), and a user who goes out of the in-house management zone is displayed on the floor or on each floor and each section. Collect the past information of the number of people who left the building or the past information of the number of people who went to work by floor. Based on this information, on the floor where there is a large number of people in the building (the number of people leaving the building) Even if there is a stop elevator, registration of the landing call is valid, and additional calls based on the user's judgment are selected and performed from the permitted operation modes. Moreover, when an imbalance occurs in a plurality of sections on one floor, an elevator that is close to a section that is frequently used is preferentially selected.

  FIG. 4 is a flowchart for explaining the operation for selecting the flexible operation, and FIG. 5 schematically shows the operation mode determined based on the number of visitors. The normal operation mode (basic operation command control) is created in step 61. When the sensor recognizes that a large number of people pass through the gate 4, a flexible operation plan in step 62 is created. For example, if the number of people passing through the gate 4 is 20 or more in 5 minutes, call for an empty car elevator is performed in step 63, and if the number of people passing through the gate 4 is 40 or more, automatic call registration is performed in step 64. carry out. If the number of people passing through the gate 4 and going to the specific floor is 40 to 69, one is commanded as a direct operation, and if 70 to 140, the two-unit direct operation of step 65 is executed. .

  For example, when the predicted number of people by destination floor is distributed as shown in FIG. 6 in the next 5 minutes, that is, in the east core 1, there are 80 users on the 6th floor and 40 users on the 16th and 17th floors. When more than one person is present, as shown in FIG. 5, two 6th floor direct elevators and one each of the 16th and 17th floor direct elevators are automatically dispatched. Similarly, since there are 81 users on the 8th floor and 40 or more users on the 16th and 17th floors in the west core 2, two elevators for direct access to the 8th floor and elevators for direct access to the 16th and 17th floors. One vehicle each is dispatched.

  FIG. 7 shows an elevator operation status guidance indicator. As shown in the drawing, the above-described situation of dispatching is displayed and output on the guidance display 71 or 72 as “6th floor direct”, “16th floor direct”, or “all floor direct”, for example. When a visitor enters the building A, a guidance indicator is installed in the vicinity of the entrance gate 4 in order to immediately recognize which elevator is serving (stopped) on which floor.

  FIG. 8 is a sketch of the lobby floor of Building B. As shown in the figure, a passage 83 is formed toward an elevator group 81 that is distributed at four locations, and a guide indicator 85 is installed at a position from the passage 83 to a branch point toward each elevator group 81. ing.

  When the user heads to the lobby floor, such as at lunch or when leaving work, the gates provided in the zones 23 and 24 in FIG. 2 detect the number of people who have left the respective compartments or zones 23 and 24. Similarly, select an elevator operation mode appropriately, for example, assign a group for each service floor or a call for a floor or a service hall for each elevator, and use this operation form early in the hallway that serves as a platform or a passage on each floor. To the person.

  In this way, it is possible to significantly reduce the waiting time of the elevator by allocating the number of elevators according to the degree of congestion of the direct driving elevator dedicated to special inter-floor movement.

  By the way, at the start or end of a meeting of a specific department, etc., or at lunch, etc., in order to alleviate the congestion, a time zone for purchasing bento lunches may be allocated to the floor or company floor to provide a time difference. The use between specific floors will increase. For example, there is a popular cafeteria on the top floor of the prefectural office building, and there are buildings where the use of elevators reaches 50% or more due to the use of the cafeteria by the staff of the related government offices and citizens. When such a user on a specific floor rides with a small number of users on a random general floor, the car is congested and the time it takes for each user to get on and off at each floor stop is a greater loss than expected. . In other words, in case of getting on and off all at once, for example, the time for getting on and off is about 0.5 seconds / person, whereas when the car is crowded 50% or more, it takes 1.2 seconds / person or more, and 65% If it becomes above, useless boarding time for the people in the vicinity of the exit to once get off the elevator and open the exit is required.

  On the other hand, in this embodiment, information on entering / exiting or entering the room for each unit time is collected for each zone, and, for example, an express train that goes directly to a crowded floor with a general-floor operating elevator group that does not cause over 50% congestion in the car Since control is performed so that an appropriate number is allocated to the operating elevator group, congestion can be alleviated at an early stage.

  In addition, a more reliable operation plan can be created by combining the number of people who have passed through the gate and past data. In other words, the usage information predicted from the past usage information data bank is estimated based on the current entrance information, and the future expected entrance demand or elevator usage demand is estimated. And based on this, the operation form of a plurality of banks is comprehensively planned. Thereby, the operation mode is improved, and a more appropriate operation mode can be selected.

  In addition, as shown in FIG. 8, a large guidance display 85 is provided on the way from an entrance gate or a cafeteria or a large conference room to a plurality of elevator halls, and by guiding the operation mode of each bank, Can prevent confusion and promote smooth use. Here, the guidance display is not limited to a large one, and for example, guidance by an appropriately sized display or an LED display suspended from the ceiling on the walls on both sides may be used, or voice guidance may be used.

  In the present embodiment, first, an increasing tendency of the number of visitors is grasped, and a time zone in which there is a concern about a lack of transportation capacity is determined based on the stored usage situation in the past. Then, by changing the number of floors in each group that are different from the normal operation mode of the elevator, or by automatically carrying out various transportation capacity enhancement operations within the range permitted by the manager, congestion in the elevator hall can be prevented. Or early resolution. In this case, the permitted operation modes include skip operation and split express operation that are suitable when the entire building is congested, as well as direct operation to specific floors or zones, and services by unit, in addition to congestion concentration on specific floors. Flexible operation by floor setting is suitable. In addition, as a countermeasure when transportation capacity is insufficient, service to these floors such as transit floors, basement floors, rooftops and executive floors is limited, and emergency elevators, VIP elevators, etc. are incorporated into group management. There is a means.

  Also, for example, in tenant buildings, hotels, and office buildings with restaurant floors where multiple companies that place importance on information confidentiality enter, the usage, section, company, race, etc. are separated. There is a case. In such buildings, based on the number of visitors and worker attribute information, for example, the number of users is estimated for each operation mode from company-specific information and data bank information, and the number of users and temporary service distribution are estimated. Carry out support driving according to actual usage or usage prediction.

  In addition, in order to increase security by automatically determining the time when the traffic volume is extremely low in all buildings such as condominiums, station buildings, large hotels, government office buildings, hospitals, etc., the response to landing calls is limited to elevators in empty cars The operation mode which avoids the riding operation by the multiple registration etc. of the destination floor is executed. Thereby, it is possible to protect personal information and switch to driving with improved crime prevention.

  As described above, according to the present embodiment, since it is possible to recognize workers and residents in the building accurately and quickly, an optimal elevator operation plan according to the traffic volume or the predicted number of users by destination floor It is possible to eliminate or alleviate congestion in the elevator hall on shared floors such as the entrance floor and cafeteria floor. In addition, even if the usage pattern in the future changes significantly, the operation mode of the elevator can be freely adapted to the manager's intention or the lack of transportation capacity, so that the optimal operation mode can be always implemented. In addition, it is possible to automatically determine a time zone in which the traffic volume is extremely low, and switch to driving that increases security.

  In the present embodiment, an example in which a gate provided with a sensor is used to detect information of a user entering or leaving the room or a room occupant is not limited to this example. An escalator is installed at the location where the escalator is used, and online information of the user is detected by calculating the number of people converted from the control information such as the current consumption in the drive system, that is, the current consumption in the drive system. Also good.

It is a sketch of the lobby floor of the building A to which the group management elevator control system according to the present invention is applied. It is a sketch of floors other than the lobby floor of building A A flow chart from when the sensor detects entry to the creation of an elevator operation plan is shown.
