Description

  The present invention relates to an elevator renewal time group management control system.

  Elevator equipment is usually renewed after a certain period of time has elapsed since the start of operation, in order to cope with aging and upgrade functions to meet the needs of the times. There are various types of renewal, such as remodeling of the entire facility, modification of only a part of the facility, or improvement of only the control-related technology, but renewal of the content in accordance with the actual situation of the field facility is appropriately selected.

  In addition, renewal of any content requires a certain period of construction, especially in large building elevator systems where multiple elevators are installed and group management control is performed. It will take a long time to complete. On the other hand, for many users of the building, the elevator is a highly public facility that must be used on a daily basis, and it is necessary to always ensure the operation of a certain number of elevators or more during the renewal construction period.

  Therefore, during the renewal construction period, the elevator that has been renewed (referred to as “new elevator” in this specification) and the elevator that has not yet been renewed (referred to as “old elevator” in this specification) are allowed to coexist. It is normal to operate. In this case, since the control specifications differ between the new elevator and the old elevator, it is difficult to perform group management control by controlling both elevators.

Therefore, conventionally, each floor of a building is divided into two zones, a new elevator service zone and an old elevator service zone, and the hall calls from the floors belonging to the new elevator service zone are among the new elevator groups. On the other hand, for the call from the floor belonging to the old elevator service zone, the optimum car is assigned from the old elevator group, and each old and new elevator group is assigned the group management control. They were performed independently of each other (see Patent Document 1).
Japanese Patent Laid-Open No. 2005-247469

  However, during the renewal work, the number of new elevators and old elevators varies from day to day (the number of old elevators is large in the initial stage and the number of new elevators is large at the end). Therefore, at the beginning of the renewal work, the waiting time for the hall call from the floor belonging to the new elevator service zone becomes longer, while at the end of the renewal work, the waiting time for the hall call from the floor belonging to the old elevator service zone. Becomes longer.

  In a large building where group management control is performed, the traffic demand for a specific floor (referred to as “specific floor” in this specification) is the other floor (“general floor” in this specification). May be much more than For example, the traffic demand on the cafeteria floor during lunch hours, or the traffic demand on the event floor immediately after the end of an event such as a movie or a music concert, is extremely greater than the traffic demand on the general floor.

  However, in the conventional system, such a specific floor is divided into zones so as to belong to either the new elevator service zone or the old elevator service zone. As described above, since the number of new elevators and old elevators varies from day to day during the renewal construction period, the elevator group having a larger transportation capacity is not necessarily assigned to a specific floor.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an elevator renewal time group management control system capable of ensuring as large a transportation capacity as possible with respect to a specific floor having a large traffic demand. It is said.

  As means for solving the above-mentioned problems, the invention according to claim 1 is that, when a hall call signal from a certain floor is inputted, whether the floor where the hall call is is a general floor or from a general floor The standard floor / specific floor determination means that determines which one of the specific floors has the highest traffic demand, and the floor where the hall call was made is renewed when the general floor / specific floor determination means determines that it is a general floor. When the new / old elevator service zone discriminating means for determining whether it belongs to the service zone of the later new elevator or the old elevator service zone before the renewal, and the general floor / specific floor discriminating means are determined to be the specific floor, always The new and old elevator number monitoring means for outputting the number of elevators of the new elevator group and the old elevator group being monitored as monitoring results, and the floor where the hall call was made If it is a floor, the response to the hall call is assigned to either the new elevator group or the old elevator group based on the discrimination result from the new and old elevator service zone discrimination means, while the floor where the hall call is located If it is a specific floor, the response to the hall call is based on the monitoring result from the new and old elevator number monitoring means, and the new and old elevator group assigning means to be assigned to the new elevator group or the old elevator group with the larger number of elevators, It is characterized by having.

  According to a second aspect of the present invention, in the first aspect of the present invention, the present invention further comprises operating status monitoring means for monitoring the operating status of both the new elevator group and the old elevator group. Based on the monitoring results of the means, if it is determined that the allocation of only one group of the new elevator group or the old elevator group as a response to the hall call on the specific floor is not sufficient to meet the traffic demand on the specific floor, , And a part or all of the elevators of the other group are allotted.

  The invention according to claim 3 is the invention according to claim 1, wherein the new and old elevator group allocating means determines that the current time belongs to a time zone in which traffic demand is expected to be excessive. The response to the hall call is assigned to one group of the new elevator group or the old elevator group and a part or all of the elevators of the other group.

  The invention according to claim 4 is the invention according to claim 1, wherein the new and old elevator group allocating means responds to a hall call on a specific floor based on an input of an allocation command by manual operation, either the new elevator group or the old elevator group. And a part or all of the elevators of the other group.

  According to the present invention, the number of elevators in the new elevator group and the old elevator group is monitored, and the elevator group with the larger number is assigned to a specific floor, so that the range of possible traffic demand on the specific floor Transport capacity can be secured.

  FIG. 1 is a configuration diagram of an elevator renewal time group management control system according to a first embodiment of the present invention. This structure shows the thing in one period during the renewal construction period, and shows the case where there are two new elevators and three old elevators. The number of these elevators will be 3 new elevators and 2 old elevators as the renewal work progresses. Further progress will result in 4 new elevators and 1 old elevator, and eventually all 5 will be new. Renovation work is completed by becoming an elevator.

  In the hoistway of the building, two new elevator cars AK1, AK2 and three old elevator cars BK3, BK4, BK5 are arranged so as to be movable up and down. The new elevator cars AK1, AK2 are controlled and operated by the new elevator controllers AC1, AC2, and the old elevator cars BK3, BK4, BK5 are controlled by the old elevator controllers BC3, BC4, BC5. The new elevator control devices AC1 and AC2 are group-controlled by the new elevator group management control device 1A, and the old elevator control devices BC3, BC4 and BC5 are group-controlled by the old elevator group management control device 1B. Yes.

  In addition, when there is a hall call from a certain floor, whether the response to the hall call is assigned to the new elevator group or the old elevator group is managed by the old and new elevator group assignment management device 2. .

  The new and old elevator group assignment management device 2 determines whether the floor where the hall call is made is a general floor or a specific floor when a hall call signal is input from the hall call button 3 of a certain floor. When the general floor / specific floor discriminating means 4 and the general floor / specific floor discriminating means 4 discriminate the general floor, the floor where the landing call was made is in either the new elevator service zone or the old elevator service zone New and old elevator service zone discriminating means 5 that discriminates whether or not it belongs based on reference to the service zone setting table 8, and new elevator groups that are constantly monitored when the general floor / specific floor discriminating means 4 discriminates a specific floor and Discrimination from the old and new elevator number monitoring means 6 that outputs the number of elevators of the old elevator group as a monitoring result, and the old and new elevator service zone discrimination means 5 Or an old or new elevator group that outputs an allocation command signal for a response to the hall call to the new elevator group management control apparatus 1A or the old elevator group management control apparatus 1B based on the monitoring result from the new or old elevator number monitoring means 6 The allocation means 7 is comprised.

  The monitoring by the new and old elevator number monitoring means 6 can be easily performed by, for example, detecting the number of connection ports between the new elevator group management control device 1A and the new elevator control devices AC1 and AC2. However, as a simpler method, an elevator administrator or the like may manually input the number of new and old elevators at the start of operation every morning and output the input result as a monitoring result.

  FIG. 2 is an explanatory diagram showing the setting contents of the service zone setting table 8 in FIG. As shown in this figure, the building in which the elevator system according to the present embodiment is installed is 10 stories, the first floor to the ninth floor are general floors, and the 10th floor is a specific floor (for example, a cafeteria floor). Yes.

  As for the general floors, the first to fifth floors are set as the old elevator service zones, and the sixth to ninth floors are set as the new elevator service zones. It is set as a floor that does not belong to.

  In addition, at the present time, it is only Units 1 and 2 (cars AK1, AK2) that can answer hall calls from floors belonging to the new elevator service zone, and can answer hall calls from floors belonging to the old elevator service zone. Is No. 3, 4, 5 (car BK3, BK4, BK5).

  Next, the operation of the first embodiment configured as described above will be described with reference to the flowchart of FIG. 3 when the floor where the hall call is made is, for example, the seventh floor, the fourth floor, and the tenth floor. Each will be explained.

  First, a case where the user presses the hall call button 3 on the seventh floor will be described. When the hall call signal from the hall call button 3 is input (step 1), the general floor / specific floor discriminating means 4 immediately recognizes that the floor associated with this hall call is the 7th floor, and further, this 7th floor It is discriminated whether it is a general floor or a specific floor (step 2).

  If the floor related to the hall call is a general floor, the general floor / specific floor determination means 4 notifies the old and new elevator service zone determination means 5 of the floor name, while the floor related to the hall call is specified. If it is a floor, the floor name is notified to the old and new elevator number monitoring means 6. In the above case, since the general floor / specific floor discriminating means 4 discriminates the 7th floor as a general floor (“YES” in step 2), the floor name “7th floor” is notified to the old and new elevator service zone discriminating means 5.

  Upon receipt of this notification, the old and new elevator service zone discriminating means 5 refers to the service zone setting table 8 and discriminates between the new and old service zones of the seventh floor (step 3). In this case, the new and old elevator service zone discriminating means 5 discriminates that the seventh floor belongs to the new elevator service zone (“YES” in step 3), and notifies the new and old elevator group assigning means 7 of the discrimination result.

  When the new and old elevator group allocating means 7 receives the notification of the determination result, the new and old elevator group allocating means 7 outputs an allocation command signal for a response to the 7th floor hall call to the new elevator group management control apparatus 1A (step 4).

  When the new elevator group management control device 1A inputs this allocation command signal, it determines which of the new elevator cars AK1 and AK2 should respond to the hall call on the 7th floor based on the driving situation, and the new elevator control device AC1, A response command signal is output to either AC2.

  Next, a case where the user presses the hall call button 3 on the fourth floor will be described. The general floor / specific floor discriminating means 4 receives the hall call signal from the hall call button 3 (step 1) and discriminates that the floor related to this hall call is the 4th floor and that the 4th floor is the general floor. After that ("YES" in step 2), the new and old elevator service zone discriminating means 5 is notified of the floor name of the fourth floor.

  Upon receipt of this notification, the new and old elevator service zone discriminating means 5 discriminates that the fourth floor belongs to the old elevator service zone (“NO” in step 3), and notifies the new and old elevator group assigning means 7 of the discrimination result.

  When the new and old elevator group allocating means 7 receives the notification of the determination result, the new and old elevator group allocating means 7 outputs an allocation command signal for a response to the 4th floor hall call to the old elevator group management control device 1B (step 5).

  When the old elevator group management control device 1B receives this assignment command signal, the old elevator group management control device 1B determines which of the old elevator cars BK3, BK4, BK5 should respond to the 4th floor hall call from the driving situation, and the old elevator control device A response command signal is output to any of BC3, BC4, and BC5.

  Finally, a case where the user presses the hall call button 3 on the 10th floor will be described. When the hall call signal from the hall call button 3 is input (step 1), the general floor / specific floor discriminating means 4 discriminates that the floor relating to this hall call is the 10th floor and that the 10th floor is the specific floor. After that ("NO" in step 2), the floor name of the 10th floor is notified to the old and new elevator number monitoring means 6.

  Upon receiving this notification, the new and old elevator number monitoring means 6 outputs the number of elevators belonging to the new elevator group and the old elevator group that have been monitored so far as monitoring results. In this case, the number of new elevators belonging to the new elevator group is two, and the number of old elevators belonging to the old elevator group is three.

  When the monitoring result is input, the new and old elevator group allocating means 7 determines the magnitude relationship between the value of the new elevator number and the value of the old elevator number (step 6). In this case, since the value of the number of old elevators is larger than the value of the number of new elevators (“new <old” in step 6), the new and old elevator group assignment means 7 assigns an assignment command for a response to the 10th floor hall call. A signal is output to the old elevator group management control device 1B (step 5).

  When the old elevator group management control device 1B receives this assignment command signal, the old elevator group management control device 1B determines which of the old elevator cars BK3, BK4, BK5 should respond to the 10th floor landing call from the operating situation, and the old elevator control device A response command signal is output to any of BC3, BC4, and BC5. However, when the traffic demand on the 10th floor is very large, the old elevator group management control device 1B may output response command signals to two or three of the old elevator control devices BC3, BC4, BC5. it can.

  In the above example, the determination result at the present time in Step 6 is that the value of the number of old elevators is larger than the value of the number of new elevators. The value should be larger than the value of the old elevators. In that case, the new and old elevator group allocating means 7 outputs an allocation command signal for a response to the 10th floor hall call to the new elevator group management control device 1A (step 4).

  According to the first embodiment described above, the specific floor is not assigned to any service zone, and when the hall call signal from the hall call button 3 is from the specific floor where traffic demand is high, The floor / specific floor discriminating means 4 discriminates that it is a hall call from a specific floor, and based on the monitoring result from the old and new elevator number monitoring means 6, the old and new elevator group allocating means 7 Since the response is assigned, it is possible to assign the transport capacity as much as possible to the specific floor where the traffic demand is high.

  FIG. 4 is a configuration diagram of an elevator renewal time group management control system according to the second embodiment of the present invention. In the configuration of the first embodiment, a response to a hall call from a specific floor is assigned to only one elevator group having a larger number of elevators among the old and new elevator groups. In the second embodiment, In addition, not only one elevator group but also the other elevator group can be assigned according to the driving situation.

  4 differs from FIG. 1 in that an operating condition monitoring means 9 and a traffic demand excessive time zone setting table 10 are added to the old and new elevator group assignment management device 2, and an assignment command signal by manual operation is sent to the old and new elevator group assignment means. 7 can be input.

  The operation status monitoring means 9 is a new elevator group for the new elevator cars AK1 and AK2 and the old elevator cars BK3, BK4, and BK5, and information on the current car position, car call and landing call registration, current passenger numbers, etc. It is input via the management control device 1A and the old elevator group management control device 1B, and it is possible to monitor the operating status of both the new elevator group and the old elevator group from these input information.

  The traffic demand excessive time zone setting table 10 is a table capable of setting a time zone in which traffic demand for a specific floor is expected to be excessive in advance. For example, the traffic demand for the cafeteria floor is usually very large during the lunch time period from about 11:30 to about 13:30. When the new and old elevator group assigning means 7 determines that the current time belongs to the lunch time zone set in the excessive traffic demand time zone setting table 10, not only one elevator group but also the other elevator group is assigned. It is like that.

  The assignment command input to the new and old elevator group assignment means 7 is generated, for example, when the elevator administrator manually operates the elevator monitoring terminal device. The elevator manager assigns the response to the hall call from a specific floor not only to one elevator group but also to some or all elevators of the other elevator group based on his / her own judgment at the site. Can do.

  Next, the operation of the second embodiment configured as described above will be described with reference to the flowchart of FIG. 5 in the case where the floor where the hall call is made is the 10th floor. Note that the flowchart of FIG. 5 is obtained by adding steps 7 to 10 to the flowchart of FIG. 3, and thus redundant description of steps 3 to 6 already described in the first embodiment is omitted.

  When the hall call signal from the hall call button 3 is input (step 1), the general floor / specific floor discriminating means 4 discriminates that the floor relating to this hall call is the 10th floor and that the 10th floor is the specific floor. After that ("NO" in Step 2), the floor name of the 10th floor is notified to the old and new elevator number monitoring means 6 and the operation status monitoring means 9.

  Upon receipt of this notification, the new and old elevator number monitoring means 6 receives the new elevator group belonging to the new elevator group as two monitoring units and the old elevator group belonging to the old elevator group as three monitoring results. Output to. In addition, when the operation status monitoring unit 9 receives this notification, it outputs the above-described various information to the new and old elevator group allocation unit 7 as monitoring results.

  The old and new elevator group allocating means 7 first determines whether the traffic demand on the 10th floor is excessive based on the monitoring result from the operation status monitoring means 9, that is, assigns only one group of the new elevator group or the old elevator group. Then, it is determined whether or not the response to the traffic demand on the 10th floor is insufficient and the transportation capacity is insufficient (step 7). If the determination in step 7 is “NO”, the process proceeds to step 6. However, since this case has already been described in the first embodiment, a description thereof will be omitted.

  If the new / old elevator group allocating means 7 determines “YES” in step 7, then, based on the input of the monitoring result from the new / old elevator number monitoring means 6, the value between the new elevator number and the old elevator number is set. Is determined (step 8). In this case, since the value of the number of old elevators is larger than the value of the number of new elevators (“new <old” in step 8), the new and old elevator group allocating means 7 are all connected to the old elevator group management control device 1B. That the elevators of the 10th floor should be assigned to the response to the hall call, and the new elevator group management control device 1A is also instructed to assign some or all of the elevators to the response to the hall call of the 10th floor (Step 10).

  When the old elevator group management control device 1B inputs this allocation command signal, all the old elevator control devices BC3, BC4, BC5 are made to respond to the hall call on the 10th floor of the old elevator cars BK3, BK4, BK5. A response command signal is output. In addition, when the new elevator group management control device 1A receives this allocation command signal, the new elevator control device AC1 makes one or two of the new elevator cars AK1, AK2 respond to the hall call on the 10th floor. , A response command signal is output to one or both of AC2.

  In the above example, the determination result at the present time in Step 8 is that the value of the number of old elevators is larger than the value of the number of new elevators. The value should be larger than the value of the old elevators. In that case, the new and old elevator group assigning means 7 instructs the new elevator group management control device 1A that all elevators should be assigned to the 10th floor hall call response, and also instructs the old elevator group management control device 1B. It is instructed that some or all elevators should be assigned to the 10th floor hall call response (step 9).

  In the configuration of FIG. 4, the new and old elevator group allocation management device 2 includes both the operation status monitoring means 9 and the traffic demand excessive time zone setting table 10, but only one of them is configured. Also good. When one of them is the traffic demand excessive time zone setting table 10, the new and old elevator group allocating means 7 determines whether or not the current time belongs to the time zone set in the traffic demand excessive time zone setting table 10. Thus, the determination in step 7 is made.

  Furthermore, in this second embodiment, the elevator administrator can determine whether the elevator is new or old based on his / her own judgment regardless of the monitoring result from the operation status monitoring means 9 as described above or the setting of the traffic demand excessive time zone setting table 10. It is possible to change the assignment contents of the elevator group assignment means 7. That is, the elevator manager can freely select the old and new elevators to respond to the 10th floor hall call by manually inputting an assignment command to the old and new elevator group assigning means 7.

  Thus, according to the configuration of the second embodiment, even when the traffic demand on a specific floor is very large, not only one group of the new elevator group or the old elevator but also one of the other group. By assigning part or all of the elevators, the elevator system can be operated in a state of full operation or near full operation, and the maximum transportation capacity can be exhibited.
