Description

FIELD OF THE INVENTION

The present invention relates to adjustable elevator installations. In particular, the invention relates to coordinating the movement of a group of elevator cars in an elevator shaft.

State of the art

The challenge arising in the development of an elevator installation is to minimize the required number of shafts used in the elevator installation, while striving to satisfy requests for the transportation of passengers and goods inside the building. Decisions aimed at reducing the number of shafts and improving maintenance include increasing the speed of the elevator, reducing the time it takes to open and close doors, improving control systems, introducing non-stop elevators, dividing the building into zones, etc. However, in multi-storey buildings, such measures can lead to anxiety when accelerating elevators, inconvenience when quickly closing doors or discomfort due to the use of a complicated system in which passengers have to change from one cabin to another once or several times to reach the desired floor.

In light of the foregoing, the present invention is directed to solving at least one of the above problems inherent in the usual coordination of movement of a group of cabins.

Disclosure of invention

The present invention relates to the coordination of the movement of a group of cabins in a mine when the mine zones served by the cabs at any given time overlap. A system of cab stops is formed for each cab, which includes a sequence of stops serving the requests assigned to the cab. Cab work is coordinated based on cab stop systems so that each cab serves its assigned requests without interacting with cab stop systems of another cab group.

An embodiment of the invention describes a method for coordinating the movement of a group of elevator cars in an elevator shaft, in which zones of the shaft serviced by cabs at any given moment overlap, including the formation of a system of cab stops for each cab containing a sequence of stops serving the requests assigned to the cab, coordination cab actions through cab stop systems, so that each cab serves its assigned requests without interacting with the cab stop systems of another cab from the cab group in. The coordination of the cabs may include the formation of a system for the shaft, combining the system of stops of the cab for a group of elevator cabs, and the implementation of the system for the shaft. The formation of a system for a mine can include the formation of a group of systems for a mine and ranking each system from a group of systems for a mine by means of predetermined parameters, taking into account the servicing of requests assigned to a group of cabins, the choice to implement the system for a mine by ranking. Coordination of cabs may also include the formation of a schedule of the sequence of stops indicated in each system of cab stops, excluding the interaction between cab stop systems of a group of cabs. In addition, the coordination of cabs may include setting a priority between the two cabs, giving preference in sending one of the two cabs from its stop relative to the departure of the other of two cabs from its stop. Aligning cabs may also include maintaining a separation distance between adjacent cabs in a mine. The operation of forming a system of cabin stops for each cabin includes introducing a conditional stop location into the system of cabin stops, so that the cabin stops at the conditional stop location only if it is necessary to maintain the separation distance from the adjacent cabin. The operation of forming a system of cab stops for each cab may include introducing a stop location to provide a path for one of the cabs, so that it stops at a stop location to provide a path while maintaining a separation distance from an adjacent cab. The operation of introducing a stop to provide a path includes moving one cab in a direction from another cab, so as to provide a separation distance. Forming a system of cab stops for each cab may include adjusting the cab stop system for each cab when changing the cab request or its condition. Forming a system of cabin stops for each cabin may also include periodic adjustments to the system of cabin stops for each cabin.

Another embodiment of the present invention describes an elevator installation comprising a group of cabs in a shaft, a controller configured to form a system of cab stops for each cab, comprising a sequence of stops serving the requests assigned to the cab, forming a system for a shaft integrating cab stop systems for a group of cabs so that each cabin serves the requests assigned to it without interacting with another cabin from the group of cabins, and regulating the operation of cabins through a system for shah you.

Another embodiment of the invention describes a method for controlling a group of cabins in an elevator shaft, comprising forming at least one system of cabin stops for each cabin, which comprises a sequence of stops serving all requests assigned to the cabin, and forming at least one system for the shaft that combines at least at least one cab stop system for each cab group such that each cab serves its assigned requests without interacting with cab stop systems of another cab from the group py of cabs, ranking each of at least one system for a mine by means of predetermined parameters, taking into account all the requests assigned to a group of cabs, implementing the highest ranking system for a mine from at least one system for a mine.

It should be understood that both the foregoing general description and the following detailed description are merely illustrative and not limitation of the invention in its claimed form.

The implementation of the invention

Figure 1 schematically shows the elevator installation 10, comprising a first elevator car 12 and a second elevator car 14, located on the same vertical relative to each other in the elevator shaft 16. In this embodiment, the shaft 16 is located in a building having twelve floors with floors L1-L12, and is designed so that the first cabin 12 and the second cabin 14 can serve passenger requests on most or all floors. The controller 18 is coupled to the first elevator lifting device 20 and the second lifting device 22. The first lifting device 20 comprises a mechanical assembly driving the first cabin 12, and the second lifting apparatus 22 comprises a mechanical assembly driving the second cabin 14.

The shaft 16 may have a configuration in which the cabin 12 serves all floors except the uppermost, access to which is prohibited due to the cab 14 being on it, and in which the cabin 14 serves all floors except the lowest due to the cab being on it 12. Alternatively, the shaft 16 may have a parking area lying below floor L1, so that the cabin 12 can be temporarily placed there to enable the cabin 14 to fulfill requests related to floor L1. Similarly, the shaft 16 may have a parking zone lying above floor L12, so that the cabin 14 can be temporarily placed there to enable the cabin 12 to reach floor L12. It should be noted that although the twelve floors L1-L12 are shown, the elevator installation 10 can be adapted to operate in a building having any number of floors. In addition, although two cabins 12 and 14 located on the same vertical are shown, any number of cabins designed to service most or all of the floors in the building can be placed in the shaft 16.

Cabs 12 and 14 are independently controlled by controller 18 (respectively, via lifting devices 20 and 22) on service requests received from call buttons installed on floors L1-L12. Controller 18 receives service orders from passengers on floors L1-L12, and controls cabs 12 and 14 so as to efficiently and safely deliver passengers to their respective destination floors. The controller 18 monitors and controls the location, speed and acceleration of each cabin 12 and 14, performing passenger requests. In some embodiments, the controller 18 determines the location and speed of the cabs 12 and 14 based on data received from position and speed sensors mounted on the lifting devices 20 and 22, respectively.

To ensure safe and efficient operation of cabs 12 and 14, controller 18 coordinates the relative movement of cabs based on a group of parameters. For example, the controller 18 ensures that the cabs 12 and 14, when fulfilling their respective passenger requests, are removed by at least a separation distance or gap, guaranteeing that there is no interaction between the cabs 12 and 14. In addition, it moves the cabs 12 and 14 towards the points the destination indicated by the passengers using the elevator (and not from the destination). Moreover, the controller 18 eliminates deadlocks between the cabs 12 and 14. The situation where the requested destination of the lower cab 12 is located above the cab 14, while the requested destination of the upper cab 14 is located below the lower cab 12 can be classified as a deadlock. A deadlock may occur if the distance between the ordered destination of one of the cabs 12, 14 and the position of the other of the cabs 12, 14 is less than the separation distance. In both cases, in order to resolve the deadlock, one of the booths 12, 14 must be forced to move in the opposite direction to the requested destination, so as to enable the other booth 12, 14 to move in the direction of the requested destination.

The controller 18 first of all forms a system of cabin stops for each of the cabs 12 and 14. Each stop in the system of cab stops is a location in a shaft 16 where cab 12 or 14 stops. For example, cabs 12 and 14 can stop to fulfill a passenger’s request to load it into the cab or to exit the cab, or stop in the position most favorable for servicing a subsequent request. The cab stop system for cabs 12 or 14 is a sequence of stops that the cabs make to fulfill all the requests assigned to them. In some embodiments, the controller 18 forms a group of cabin stop systems for each of the cabs 12 and 14 to provide an alternative sequence of stops to ensure that the requests assigned to that cabin are fulfilled.

The controller 18 then forms a system for the mine, consisting of a system of cab stops for each of the cabs 12 and 14, as well as coordination information for the cab. The coordination information may include additional stops in the cab stop systems and / or a set of priorities, each of which relates a stop in the cab stop system of one of the cabs 12 and 14 to a stop in the cab stop system of the other of cabs 12 and 14. As an example in FIG. .2 curves are given showing the coordination of the movement of the cabs 12 and 14 in the shaft 16 as a function of time, and FIG. 3 is a view of a shaft system that determines the coordination of the movement of the cabs 12 and 14. In FIG. 2, the position of the cab 12 is displayed by a curve 30, and by dix cab 14 displays the curve 32. Initially cab 12 and 14 are arranged as shown in Figure 1, in which the cab 12 is at the L5 floor and cab 14 on floor L10. The cab stop system for cab 12 includes a stop on floor L6 for a passenger to board, followed by a stop on floor L8 for a passenger to exit. The cab stop system for cab 14 includes a stop on floor L9 for a passenger to board, followed by a stop on floor L7 for a passenger to exit.

To prevent a deadlock between cabs 12 and 14, controller 18 can give priority to cab 12 to service its stops on floors L6 and L8 over cab service 14 of floors L9 and L7. The controller 18 can give priority to the cabin 12 by increasing the duration of the stop of the cab 14 on the floor L10. Accordingly, the controller 18 forms a system for the mine, shown in FIG. 3 and containing the system of cab stops for two cabs, as well as priorities, ensuring the cab 12 is sent from the floor L8 before the cab 14 leaves the floor L10 (which is represented by the arrow passing from the cab 12 stop on floor L8 to cab stop 14 on floor L10). In this embodiment, the mine system includes one priority, but it is understood that this system may include any number of priorities. In figure 2, the departure of the cabin 12 from floor L8 is indicated by point 34 on curve 30, while the departure of cabin 14 from floor L10 is indicated by point 36 on curve 32. Based on the presented example, point 34 in time arises no later than point 36.

The shaft system can be implemented by the controller 18 in several ways. In the first embodiment, the priority setting is implemented in the elevator shaft, and each of them is associated with the command for the movement of cabs 12 and 14. In the example system for the shaft described in connection with FIG. 2, priority is ensured by the departure of the cab 12 from floor L8, it precedes the departure of cabin 14 from floor 10. Consequently, while setting priorities, the controller 18 does not operate cabin 14 to move from floor L10 to floor L9 until it moves cabin 12 from floor L8 to floor L5 . In this case, the duration of the stop of the cab 14 on the floor L10 can be increased.

With a different approach to the implementation of the system for the mine, a movement schedule for each of the cabs 12 and 14 is compiled. point 34) in time is earlier or at the same time as the departure time of cabin 14 from floor L10 (point 36). In the system for the shaft, time diagram information can be added, which determines the time points at which the controller 18 can start moving to each stop according to the cabin stop systems for cabs 12 and 14. If events in the elevator shaft are not implemented according to the schedule (for example, if the passenger keeps the elevator doors open for a long period of time, allowing a large group of passengers to enter), the schedule of all future traffic initializations can be adjusted accordingly.

The controller 18 also coordinates the operation of the booths 12 and 14, ensuring that they always remain at least at a separation distance. The separation distance can be, for example, several floor levels (for example, one or two floor levels) or a certain distance (for example, 5 m). In the example shown in FIG. 2, the separation distance supported by the controller 18 is two story levels. The separation distance is maintained by prioritizing, in which the controller 18 delays the departure of the cabin 14 from the floor L10 until the cabin 12 starts moving from the floor L8. After cab 12 starts moving to floor L5, cab 14 can start moving to its stop on floor L9.

In order for cabin 14 to fulfill its assigned stop on floor L7, the shaft system may include an additional stop for cabin 12 when driving to floor L5. This additional stop of the cab 12 may be called a stop to provide a path, as it places the cab 12 in a position that allows the cab 14 to reach the stop indicated in its cab stop system. Stops to provide a path include stops that are added to the cab stop system when forming a mine system (i.e., stops to provide a path are not part of individual cab stop systems) and are entered as necessary to maintain the separation distance between cabs 12 and 14 when implementing a system for a mine. If the cabin has a stop to provide a path that is not the last stop in the stopping system for a given cabin, there is a priority between a stop included in the stopping system of the adjacent cabin and a stop to provide a path. Priority ensures that the departure of an adjacent cabin from a particular stop precedes the departure of the cabin from a stop to provide a path.

The separation distance can also be maintained by introducing conditional stops into the shaft system. Like stops to provide a path, conditional stops are stops added to the cabin stop system when forming the mine system and introduced if necessary to maintain the separation distance between the cabs 12 and 14 when implementing the mine system. For each conditional stop, there is a priority ensuring that one cab does not go to the next one after the conditional stop until the next cab goes to a specific stop. Thus, for one cabin, it may be necessary to stop at a conditional stop and wait until another, neighboring cabin reaches a specific stop or leaves a specific stop in accordance with the setting of priorities. However, the cab does not need to stop at a conditional stop if priority setting has already been completed, which is the case if the neighboring cab has already reached a specific stop and left it in accordance with the priority.

To illustrate, figure 4 presents the system for the mine, containing a conditional stop. Under this system, for a mine, cabin 12 starts moving on the LI floor and has a stop on the L8 floor. The cab stop system for cab 14 starts on floor L9 and includes successive stops on floors L5, L12 and L10. In this example, a separation distance of two floors is used, that is, there must be at least two floors between the two cabs 12, 14 at all times.

In order to ensure that the cabs 12 and 14 remain at all times separated by a separation distance, and there is no deadlock, a conditional stop for the cab 12 on the floor L3, indicated by brackets in FIG. 3, has been introduced into the shaft system shown in FIG. . By way of explanation, if the elevator car 12 is ready to leave the LI floor to move to the L8 floor, but at the same time the car 14: a) is still on the L9 floor, b) is on the way to the L5 floor, or c) is stopped on the L5 floor, then cab 12 makes a conditional stop on floor L3. Cabin 12 waits on floor L3 until cabin 14 leaves floor L5 and heads for floor L12. An arrow going from floor L5 in the stopping system for cabin 14 to a conditional stop on floor L3 in the stopping system for cabin 12 indicates priority (i.e., cabin 14 must leave floor L5 before cabin 12 leaves floor L3). On the other hand, if cabin 14 made its stop on floor L5 and started moving to its next stop on floor L12 by the time cab 12 reached floor L3, then stopping cabin 12 on floor L3 is not needed.

For each group of cab stop systems, controller 18 can generate alternative mine systems, each of which provides for the execution of requests assigned to cabs 12 and 14. For example, in addition to the example described with reference to figures 2 and 3, controller 18 can alternatively coordinate movement cabins 12 and 14, assigning priority to cab 14 when servicing its stops on floors L9 and L7 over cab 12 when servicing its stops on floors L6 and L8. Figure 5 shows curves showing alternative coordination of the movement of the cabs 12 and 14 in the shaft 16 depending on the time by which the system for the shaft includes a priority that determines that the departure of the cabin 14 from the floor L7 precedes the departure of the cabin 12 from the floor L5. The position of the cabin 12 is displayed by curve 40, and the position of the cabin 14 is displayed by curve 42. The departure of the cabin 12 from floor L5 is indicated by point 44 on curve 40, and the departure of the cabin 14 from floor L7 is indicated by point 46 on curve 42. Based on the above example, point 44 time arises not earlier than point 46.

In order to enable cabin 12 to make an assigned stop on floors L6 and L8, a stop can be added to the shaft system to provide a path for cabin 14 to be moved to floor L10. The controller 18 coordinates the movement of the cabs 12 and 14, delaying the start of the movement of the cab 12 on the floor L6 until he makes the movement of the cab 14 from the floor L7 to a stop to provide a path on the floor L10. Alternatively, a schedule may be generated according to which the departure time of cabin 14 from floor L7 (point 46) is no later than the departure time of cabin 12 from floor L5 (point 44).

It should be noted that the above systems for the mine are just an illustration, and a group of such systems is available that provide service for stops that are indicated in the cabin stop systems for cabs 12 and 14. In addition, if the controller 18 forms a group of stop systems for each of the cabs 12 and 14 , then the number of possible alternative systems for the mine increases even more.

If the controller 18 forms a group of systems for a mine, it can use the ranking or scoring function of a group of systems for a mine to determine the best option for such a system. To make such a determination, controller 18 may take into account information related to the operation and performance of the elevator installation 10. For example, to rank or assign scores to each system for a mine, controller 18 may take into account predicted waiting times for passengers of cabs 12 and 14 (on based on the estimated time of entry and exit), the number of additional coordinating stops (that is, stops that do not serve passenger requests) for cabs 12 and 14 for each mine system and the amount of delay at each stop . Information taken into account when ranking systems for a mine or assigning points to them (as well as the importance of the type of information when ranking or assigning points) can be entered into controller 18. If controller 18 determines the highest or most preferred ranking or assigning points according to the principle laid down in the program system for the mine, he selects this system and implements it.

Cab stop systems for cabs 12 and 14 are dynamic concepts in the sense that controller 18 can correct these systems. For example, the cab stop system can be adjusted if the requests for cab 12 or 14 have changed. In the above example, if cab 12 is supposed to receive a passenger on floor L7 after it stops on floor L8 and unload the same passenger on floor L6, these two additional stops can be entered into the stop system of cabin 12 between its stop on floor L8 and the stop to provide a path on floor L5. If any of the cab stop systems is changed, the controller 18 may form one or more additional shaft systems based on the adjusted cab stop systems.

Alternatively, the controller 18 may generate additional systems for the mine periodically (for example, every 10 ms) regardless of changes in passenger requests. In any case, the controller 18 may then rank the additional systems for the mine based on the ranking or scoring function described above, and then implement the highest or most preferred ranking or scoring system for the mine.

Figure 6 presents a block diagram of a method for coordinating the movement of cabs 12 and 14 in a mine. First, in step 50, the controller 18 generates cabin stop systems in the shaft 16 for each of the cabs 12 and 14. If cab stop systems for the cabs 12 and 14 are formed, then the controller 18 in step 52 generates the shaft systems that coordinate the cab stop systems 12 and 14. Each system for the mine is designed in such a way that each of the cabs 12 and 14 serves its assigned requests without interacting with the cab stop system of the other cab 12 and 14. Coordination can be carried out by defining and implementing I prioritize or schedule and follow it. The controller then calculates the forecast time at which each cab arrives at the stop and leaves it, and takes into account the effect on the delay of passengers when they wait for the cab to arrive, wait for the stopped cab to start moving, or wait for the cab to arrive at their destination floors. Based on these calculations or other criteria in step 54, the controller ranks or assigns points to the mine systems to determine which one is best for implementation. Then, in operation 56, the controller selects and implements the highest or most preferred ranking system for the mine. Since coordination is a dynamic process, the controller 18 then determines in step 58 whether an additional system or systems for the shaft should be formed. Additional systems for the mine can be formed, for example, by any changes in passenger requests relating to any of cabs 12 and 14 (or both cabs) or be formed periodically at time intervals programmed in controller 18. If controller 18 does not need to form additional system for the mine, the method returns to the optimal system for the mine, carried out in operation 56. If, however, in decision 58, it turns out that the controller 18 needs to form an additional system for mine, the method returns to step 50.

The present invention relates to the coordination of the movement of a group of cabins in a mine. A system of cab stops is formed for each cab, which includes a sequence of stops serving the requests assigned to the cab. Then, the operation of the cabs is coordinated by means of cab stop systems so that each cab serves its assigned requests without interacting with cab stop systems for any other cab group. In some embodiments, at least one mine system is formed, and each of the at least one mine system is ranked based on predetermined parameters, taking into account service requests assigned to a group of booths. Then the highest or most preferred ranking system for the mine is executed. Coordination in this way of the movement of a group of cabins in the mine: each cab safely and efficiently serves its requests without interacting with the movement of another cab or cabs in the mine. In addition, the system or systems for the mine can be adjusted when changing requests for each cabin, which ensures constant safety and efficiency of the cabs.
