Description

  The present invention relates to a group management elevator that efficiently controls the allocation of a plurality of elevators, and is particularly suitable for a large complex building having a plurality of banks that eliminates the congestion of transit and increases the operation efficiency.

  In recent years, many large-scale complex buildings in which commercial facilities and offices are mixed have been built. Generally, commercial facilities are often arranged in a lower layer, and office buildings are often arranged in a layer higher than the lower layer. Furthermore, when there are many floors of office buildings, the office buildings arranged in the upper level are divided into a plurality of banks, such as an elevator for the middle floor and an elevator for the higher floor, to improve driving efficiency.

  In this case, the office user goes to the transit floor by a shuttle elevator (reciprocating only a specific floor) that jumps from the main lobby floor (1st floor) to a commercial facility. (Local elevators that stop on each floor) or elevators for higher floors (local elevators that stop on each floor) will be used. In addition, when the elevator is arranged so that the elevator for the middle floor and the elevator for the higher floor are based on the main lobby floor (the first floor), the office user can use the elevator from the main lobby floor to the middle floor or the upper floor. You will get on the elevator to the floor and arrive at the destination floor.

  Conventionally, when traffic demand temporarily increases on a specific floor, it is known that multiple elevators can respond to landing calls (centralized service operation) in order to handle traffic demand bias early. For example, it is described in Patent Document 1.

  In addition, there will be a bank of shuttle elevators that operate directly between the main lobby floor and the transfer floor, and a bank of local elevators that service the upper floor including the transfer floor to facilitate the transfer between the shuttle elevator and the local elevator. The operation between the shuttle elevator and the local elevator is related, and when the load of one elevator is more than the predetermined value, that is, full, the other elevators are called to the connecting floor or are waiting on the connecting floor It is known to delay the departure of the elevator and is described in Patent Document 2.

  In recent years, with the redevelopment of cities and regions, there are offices, houses, hotels, stores, conferences in buildings, complex commercial facilities, or buildings that have multiple facilities such as shopping centers, entertainment facilities such as restaurants and cinemas, etc. The skyscraper complex where the room is occupying is becoming larger and larger, and in this case, it is indispensable to provide multiple banks of local elevators, simply by applying those described in Patent Documents 1 and 2, It is difficult to respond. For example, after boarding a shuttle elevator, centralized service operation of multiple bank elevators or delayed departures will not enable smooth connections, and the overall transport efficiency will deteriorate even though the number of elevators is increased. It is not suitable for energy saving.

  In particular, those that delay the departure of elevators waiting on the transfer floor, the larger the number of elevators and the larger the elevator, the longer it takes for users to move between banks, and the longer the delay time. Not only does this have to happen, but individual differences in travel time increase, and users who have already been on board will wait.

  The object of the present invention is to solve the above-mentioned problems of the prior art and to improve serviceability and improve transportation efficiency and energy-saving performance by eliminating user dissatisfaction even in the case of a larger skyscraper composite building or the like. It is in.

In order to achieve the above object, the present invention provides a bank of shuttle elevators operating between a main lobby floor and a transit floor and having a plurality of elevators, and serving an upper floor including the transit floor to provide a plurality of In a group management elevator of a plurality of banks provided with a bank of local elevators having an elevator, a plurality of banks of the local elevator are provided, and whether or not the shuttle elevator bank is congested based on a boarding rate of the shuttle elevator determine congestion detection signal indicating the result of judgment that the congestion is transmitted to the plurality of banks of the local elevators, reception vital the transit floor of the congestion detection signal of the plurality of banks of the local elevators in the bank hall call has been registered by the landing call button, In which few cars of the local elevators are dispatched to the transit floor.

According to the present invention, when the shuttle elevator is congested, a plurality of elevators respond to the transit floor in the bank of local elevators where the landing call is registered by the transit call button on the transit floor. Even in a high-rise complex building, etc., it is possible to eliminate user dissatisfaction, improve serviceability, and improve transportation efficiency and energy saving.

The congestion determination processing flowchart by one Embodiment. The central service driving | operation command flowchart by one Embodiment. The concentrated service driving | operation command flowchart by other embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  Fig. 1 shows the arrangement of elevators in a building, and in high-rise complex buildings, etc., in order to expand the low-rise rental space, the middle floor of the building (the 10th floor in Figure 1, Hereinafter, there will be a shuttle elevator that provides direct operation between the main lobby floor (1st floor) and the transfer floor (10th floor).

  In order for the user to go to the office located above the commercial facility, the office user gets into one of the shuttle elevators of Units 1 to 8 from the main lobby floor (1st floor), and the transfer floor (10th floor) ) And get on either the local elevator for the middle floor (No. 9-16) or the local elevator for the higher floor (No. 17-24).

  Next, taking the time of going to work as an example, a description will be given by performing a centralized service operation of the middle and high-rise local elevators according to the congestion situation of the low-rise shuttle elevator. In the down-peak traffic flow such as the first half of lunch, conversely, the central service operation of the low-rise shuttle elevator will be implemented according to the congestion situation of the middle and high-rise local elevators.

  The service floor of each elevator will be described as a complex building with 26 floors. The 1st to 9th floors are commercial facilities, and the 11th to 26th floors are offices. The 10th floor is a transit floor, 8 shuttle elevators (units 1-8) that run directly on the 1st floor (main lobby floor) and 10th floor (transfer floor), each floor between the 10th and 18th floors Eight local elevators for the middle floor (No. 9 to 16), 8 local elevators for the upper floors (No. 17 to 24) serving each floor between the 10th, 18th and 26th floors . A local elevator for the middle floor (No. 9 to 16) and a local elevator for the upper floor (No. 17 to 24) are banks, and a plurality of banks operated from the connecting floor are arranged.

  FIG. 2 is a block diagram of the entire control unit that operates each elevator, and the shuttle elevator group management control device 10 controls the control devices 11 to 18 of the eight elevators. Each of the control devices 11 to 18 is provided with boarding rate measuring means 111 to 118, and the boarding rate is measured by detecting a load with a scale device provided on the car floor and comparing it with a reference value. The signal of the boarding rate measured by the boarding rate measuring means 111 to 118 is transmitted to the shuttle elevator group management control device 10 and is compared with a predetermined reference value of the boarding rate by the congestion judging unit 200 and is in a congested state. A congestion detection signal indicating that it has been determined that.

  The congestion detection signal is transmitted to the local elevator group management control device 20 for the middle floor and the local elevator group management control device 30 for the higher floor. Therefore, when the shuttle elevator departs from the first floor (main lobby floor), each bank knows whether or not the shuttle elevator is congested. The group management control device 20 for the local elevator for the middle floor controls the eight elevator control devices 21 to 28, and the group management control device 30 for the local elevator for the upper floor controls the eight elevators. The devices 31 to 38 are controlled.

  The group management control device 20 for the local elevator for the middle floor and the group management control device 30 for the local elevator for the upper floor are provided with the central service operation commands 300 and 301, and create the central service operation command signal according to the congestion detection signal. If the shuttle elevator is congested at the time of departure from the first floor (main lobby floor), it is possible to immediately start or prepare a centralized service for dispatching a plurality of elevators to the connecting floor. In order to cope with the down-peak traffic flow, the occupancy rate measuring means 121 to 128 and 131 to 138 are also provided in the control devices 21 to 28 and 31 to 38 of the local elevator. The operations of the hall call buttons 401, 501, and 601 are input to the corresponding group management control devices 10, 20, and 30 and registered as hall calls.

FIG. 3 shows a processing flowchart of the congestion determination means 200.
(1) Initial value setting of loop processing (n = 1, F1 = 0, F2 = 0) (step 201)
(2) When the boarding rate exceeds the first boarding rate (60%), the congestion determination signal F1 is set (F1 = 1) (steps 211 to 213).
(3) When the boarding rate exceeds the second boarding rate (50%), the congestion release determination signal F2 is set (F2 = 1) (steps 214 to 215).
(4) When all units are processed and the congestion determination signal F1 is set, it is determined that the traffic is congested.

  As described above, the occupancy rate when each of the eight shuttle elevators (units 1 to 8) departs from the first floor is monitored. The congestion determination is configured such that once it is determined as being congested, the congestion determination is continued for a certain period of time, and if the congestion is moderated to some extent, the congestion determination can be canceled.

  The first boarding rate is set to 60%, the second boarding rate is set to 50%, the first time period is set to 5 minutes, and the second time period is set to 5 minutes. If the rate exceeds 60%, the congestion detection signal is set (determined as congestion) until the first time limit of 5 minutes elapses (step 221).

  In addition, after exceeding the first time limit of 5 minutes, between the present time and the second time limit of 5 minutes, if any elevator has not exceeded the second boarding rate of 50%, the congestion detection signal is reset (Step 222).

  As described above, once it is determined that the vehicle is congested, by continuing the congestion determination under a predetermined condition, it is possible to appropriately deliver a plurality of vehicles without performing a departure delay considering the walking time.

FIG. 4 shows a processing flowchart of the centralized service operation commands 300 and 301 shown in FIG.
In the state where the congestion detection signal transmitted from the shuttle elevator group management control device 10 is received, a centralized service operation is performed when a landing call on the 10th floor which is a transit floor is registered (steps 301 to 303). .

  FIG. 5 shows that the centralized service operation command is started when the local elevator boarding rate (predetermined value 50%) is exceeded in the processing flowchart of the centralized service operation commands 300 and 301 shown in FIG. That is, in FIG. 4, the start condition of the centralized service operation is registered as hall call registration, but in this figure, it depends on the boarding rate of the local elevator.

  With the processing shown in FIG. 4 and FIG. 5, centralized service operation can be appropriately started in a timely manner so as to improve transportation efficiency for a bank where congestion is expected. It is desirable to adjust the time limit for enabling the centralized service operation by, for example, the boarding rate. Further, the centralized service operation command is a combination of the processing flowcharts of FIGS. 4 and 5, that is, when a hall call on the 10th floor, which is a transit floor, is registered or when the local elevator boarding rate (predetermined value 50%) Combining as in the case can improve efficiency in response to congestion.

  Furthermore, in order to quickly return the selected second and subsequent elevators to the transfer floor, priority is given to the service with respect to the hall call on the specific floor, so that further improvement in driving efficiency can be achieved.

  As described above, when a centralized service operation is commanded to the local elevator to be transferred according to the congestion status of the shuttle elevator, the elevator in the optimal bank among the multiple bank local elevators performs the centralized service operation and the travel time varies depending on the individual. It is possible to realize a comfortable connection including users who have already boarded without being influenced.
