[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0046] The elevator group control method provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown. Among them, the elevator group 102 communicates with the server 104 through a network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed in the cloud or other network servers. The elevator group 102 includes passenger elevators and goods elevators. When the server 104 receives the goods transportation call registration information, it obtains the current operating status information of the elevator group 102. The goods transportation call registration information is used to represent the goods transportation elevator usage requirement. The server 104 determines a first elevator according to the goods transportation call registration information and the current operating status information. The first elevator is one of the goods elevators. The server 104 determines whether a second elevator meets other elevator usage requirements except for the goods transportation elevator usage requirement according to the current operating status information, and predicts the elevator usage requirement. The second elevator is other elevators in the elevator group except the first elevator. When the second elevator meets other elevator usage requirements except for the goods transportation elevator usage requirement and predicts the elevator usage requirement, the server 104 controls the first elevator to execute a dedicated goods transportation response mode. The first elevator directly reaches the goods transportation demand call floor based on the goods transportation call registration information in the dedicated goods transportation response mode. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0047] As described in the background art above, in scenarios where elevators are used to transport special goods such as building materials for decoration, large furniture, and objects with strong odors, in order to ensure the safety and comfort of other passengers during elevator rides, it is necessary to separate people and goods as much as possible and provide dedicated services. However, in general residential buildings, the number of elevators is relatively small, and all elevators need to be included in the same passenger elevator group to achieve the highest transportation efficiency. Therefore, there is no condition to configure dedicated freight elevators. When needed, only one elevator in the passenger elevator group can be designated and equipped with protective decoration as a nominal freight elevator. Currently, the operation of calling a designated elevator in the elevator group to transport special goods is not user-friendly.

[0048] During the waiting stage, the existing technologies mainly include general group control call, specific elevator call, VIP call, etc. General group control call cannot call a designated elevator. Specific elevator call does not remove the nominal freight elevator from the group, and there may be other passengers in the elevator when it arrives, which is inconvenient for transporting special goods. If the VIP call method is used to make the nominal freight elevator come empty immediately to respond and provide dedicated services, on the one hand, the priority of transporting special goods is too high, which will reduce the elevator-riding efficiency of other normal passengers; on the other hand, open use will lead to abuse, and authorizing specific people to use it will increase the workload of property managers.

[0049] During the transportation stage, the existing technologies use load detection or visual recognition of goods. When it is detected that the elevator is full or there is insufficient remaining space in the car, it enters the direct running mode. It cannot identify special goods that are not suitable to be transported with other passengers, nor can passengers actively request to enter the direct running mode.

[0050] Overall, the existing technologies do not have a suitable method for coordinating passenger needs in the passenger elevator group for goods transportation call and dedicated services, and cannot balance the transportation efficiency, the comfort of general passengers, and the convenience of transporting special goods.

[0051] Therefore, for the above reasons, in an exemplary embodiment, as Figure 2 shown, a method for regulating an elevator group is provided. Taking the server 104 in Figure 1 as an example, it includes the following steps S202 to S206. Among them:

[0052] S202, when receiving the freight elevator call registration information, obtain the current operating status information of the elevator group; the freight elevator call registration information is used to represent the demand for using an elevator for freight.

[0053] Among them, the freight elevator registration information can specifically refer to the call floor for freight elevator demand and the destination floor for freight elevator demand; the current operating status information of the elevator group can refer to the real-time operating status of multiple elevators, including, specifically, the call registration information of each floor, the destination floor registration information of each elevator, the position of each elevator, the load of each elevator, the fault information of each elevator, etc.

[0054] Exemplarily, in the waiting halls of each floor, another call operation different from the normal passenger call is provided for freight elevator registration. This operation includes, but is not limited to, long-pressing a button for registration or adding a dedicated freight call button for registration. Further, on the same floor, it is allowed to separately register the call for normal riding and the call for freight elevator, or register the call for normal riding and the call for freight elevator simultaneously, and the registration status of these two demands can be separately displayed to the waiting passengers through a display screen. For example, assuming there is a cargo to be transported from the 1st floor to the 10th floor, the user can long-press the button "10" on the elevator operation interface in the waiting hall on the 1st floor to complete the freight elevator call registration in the server of the elevator group; that is, at this time, the "1st floor" is the call floor for freight elevator demand, and the "10th floor" is the destination floor for freight elevator demand. After receiving the above-mentioned freight elevator call registration information, the server obtains the call registration information of each floor in the elevator group, the destination floor registration information of each elevator, the position of each elevator, the load of each elevator, the fault information of each elevator, etc.

[0055] S204, determine the first elevator according to the freight elevator call registration information and the current operating status information; the first elevator is one of the freight elevators.

[0056] Among them, for a conventional elevator group, it generally includes passenger elevators and freight elevators. For example, at least one elevator can be set in the elevator group as a freight elevator for transporting goods. When the freight elevator is not needed for transporting goods, it can serve in the elevator group equivalent to a general passenger elevator.

[0057] Exemplarily, the call floor for freight elevator demand and the destination floor for freight elevator demand can be obtained from the freight elevator call registration information, and the call registration information of each floor, the destination floor registration information of each elevator, the position of each elevator, the load of each elevator, the fault information of each elevator, etc. can be obtained from the operating status information. Based on the above information, factors such as the distance and time for each freight elevator to reach the destination floor for freight elevator demand, the overall load of the motors of the elevator group, and the idle degree of each freight elevator can be calculated in real time and comprehensively. An elevator is selected from among many freight elevators as the first elevator to respond to the above-mentioned freight elevator call demand.

[0058] S206. According to the current operating status information, determine whether the second elevator meets other elevator usage requirements except for the freight elevator usage requirement in the current elevator usage requirements, and predict the elevator usage requirements; the second elevator is the other elevators in the elevator group except the first elevator.

[0059] Among them, as can be seen above, the elevator group generally includes passenger elevators and freight elevators, and there is generally at least one freight elevator. After selecting the first elevator, the remaining elevators can all be used as the second elevator, that is, the second elevator includes passenger elevators and the remaining freight elevators except the first elevator. The current elevator usage requirements can be elevator usage requirements except the above-mentioned freight call requirements, such as the elevator requirements of all passengers on all floors in the current building, including but not limited to going to specific floors, transporting goods, etc. The predicted elevator usage requirements refer to predicting future elevator requirements based on historical data, daily activities of the building, etc., such as predicting the number of passengers and elevator requirements during peak hours in the morning and evening.

[0060] Exemplarily, as can be seen above, the operating status information includes the call registration information of each floor station, the destination floor station registration information of each elevator, the position of each elevator, etc. Through the above information, it can be determined whether the second elevator can meet the current call requirements of each floor station that has been registered after excluding the first elevator; further, based on factors such as historical data and daily activities of the building, predict future elevator usage requirements, and combine the number and scheduling of the second elevator, etc., and then determine whether only using the second elevator for transportation allocation can meet the predicted elevator usage requirements.

[0061] S208. When the second elevator meets other elevator usage requirements except for the freight elevator usage requirement in the current elevator usage requirements, and the predicted elevator usage requirements, control the first elevator to execute the dedicated freight response mode; the first elevator directly reaches the freight demand call floor based on the freight call registration information in the dedicated freight response mode.

[0062] Among them, the second elevator meets other elevator usage requirements except for the freight elevator usage requirement in the current elevator usage requirements, and the predicted elevator usage requirements, indicating that at this time and for some time in the future, without calling the first elevator to participate in transportation scheduling, the transportation efficiency can also be guaranteed, that is, normal passengers do not need to wait too long or share the same elevator with goods. In the dedicated freight response mode, the first elevator no longer responds to other call requirements in the waiting hall, directly responds to the freight call registration information, does not stop in the middle, and directly reaches the freight demand call floor.

[0063] In the above embodiments, when receiving the freight elevator call registration information, a freight elevator is selected from a plurality of freight elevators as the first elevator according to the freight elevator call registration information and the current operating status information of the elevator group, so that it only serves the current freight elevator use demand; further, according to the current operating status information of the elevator group, it is determined whether the remaining elevators can meet other elevator use demands and predicted elevator use demands in addition to the current freight elevator use demand when the first elevator does not participate in the transportation dispatching. Only when both are met, the first elevator is controlled to respond to the current freight elevator use demand and directly reach the freight demand call floor registered by the current freight elevator call registration information, so as to coordinate the general passenger transportation demand in the passenger elevator group, summon the designated elevator to provide dedicated services for special goods that are not suitable to be transported with other passengers, thus achieving the guarantee of the comfort of general passengers and the convenience of transporting special goods without reducing the transportation efficiency.

[0064] In an exemplary embodiment, after the step of determining whether the second elevator can meet other elevator use demands and predicted elevator use demands in addition to the current freight elevator use demand according to the current operating status information, it further includes:

[0065] S302, when the second elevator can meet other elevator use demands in the current elevator use demand except the freight elevator use demand but does not meet the predicted elevator use demand, control the first elevator to execute the freight preparation mode; the call answering priority of the first elevator in the freight preparation mode is lower than that of the second elevator, and the call answering priority is used to represent the response speed to other elevator use demands and predicted elevator use demands except the freight elevator use demand.

[0066] Among them, the second elevator can meet other elevator use demands in the current elevator use demand except the freight elevator use demand but does not meet the predicted elevator use demand, which means that in the case of not using the first elevator to participate in the transportation dispatching of the elevator group, within a certain period in the future after the current moment, the passenger demand in the building may exceed the carrying capacity of the existing elevators. For example, during the evening rush hour, the number of passengers in the building may exceed the current moment, resulting in an increase in elevator demand. If the carrying capacity of the second elevator is not enough to meet the demand during this period, passengers may need to wait longer or crowd into the existing elevators, thus causing a very poor user experience.

[0067] Exemplarily, in the above case, by controlling the first elevator to execute the freight preparation mode, the call response priority of the first elevator in the freight preparation mode is made lower than that of the second elevator, and the second elevator is preferentially used to meet other elevator usage requirements except for the freight elevator usage requirements, as well as the predicted elevator usage requirements, so as to reduce the scheduling of the first elevator, enabling the server to use the first elevator to respond to the current freight elevator usage requirement as soon as possible and avoiding excessive waiting time. For example, after calculating the predicted elevator usage requirement at the current moment, it is determined that the first elevator needs to be involved in transportation scheduling to meet the predicted elevator usage requirement obtained at this time. However, at a certain moment after the current moment (such as after a certain elevator in the second elevator completes a passenger transportation), a new predicted elevator usage requirement is recalculated. At this time, it is determined that only using the second elevator can also meet the new predicted elevator usage requirement. Since the call response priority of the first elevator for other elevator usage requirements except for the freight elevator usage requirement, as well as the predicted elevator usage requirement, is lower than that of the second elevator, for other elevator usage requirements except for the current freight elevator usage requirement, as well as the new predicted elevator usage requirement, the second elevator can respond preferentially. Under the separate control of the server, the first elevator can quickly respond to the current freight elevator usage requirement and avoid excessive waiting time.

[0068] In an exemplary embodiment, after the step of determining whether the second elevator meets other elevator usage requirements except for the freight elevator usage requirement in the current elevator usage requirement, as well as the predicted elevator usage requirement, according to the current operating status information, it further includes:

[0069] S304, in the case where the second elevator does not meet the current elevator usage requirement, controlling the first elevator to execute the passenger mode; the call response priority of the first elevator in the passenger mode is equal to that of the second elevator, and the call response priority is used to characterize the response speed for other elevator usage requirements except for the freight elevator usage requirement, as well as the predicted elevator usage requirement.

[0070] Among them, when the second elevator does not meet the current elevator usage requirement, it indicates that the current elevator usage requirement is relatively tight, and the first elevator also needs to be involved in parameter transportation scheduling to alleviate the problem of insufficient transportation capacity.

[0071] Exemplarily, in the case where the second elevator does not meet the current elevator usage requirement, the call response priority of the first elevator for other elevator usage requirements except for the freight elevator usage requirement, as well as the predicted elevator usage requirement, is set to be the same as that of the second elevator, so that the first elevator is used for the scheduling of other elevator usage requirements except for the freight elevator usage requirement, thereby alleviating the current problem of insufficient transportation capacity.

[0072] In an exemplary embodiment, the freight call registration information includes the freight destination floor station, and the method further includes:

[0073] S402. When the first elevator directly reaches the floor summoned for goods transportation, obtain the environmental parameters inside the first elevator.

[0074] Among them, the environmental parameters can refer to parameters such as the contour and area of objects inside the elevator, and the change in elevator load.

[0075] Exemplarily, for obtaining the contour and area of objects inside the elevator, it can be achieved by using visual sensors (such as cameras) installed inside the elevator to identify the contour and area of objects inside the elevator. For obtaining the change in elevator load, it can be obtained by using pressure sensors installed at the bottom of the elevator. It should be noted that the above embodiments are only for illustration and are not limited here.

[0076] S404. Determine whether there are goods inside the first elevator according to the environmental parameters.

[0077] Exemplarily, based on parameters such as the contour and area of objects collected inside the elevator, comprehensively analyze the data of the collected object contour and area, and the change in elevator load. If the contour and area of the object are significantly larger than the normal situation, or the change in elevator load is significantly higher than the normal situation, then it is determined that there may be goods transportation. In addition to judging whether there are goods inside the first elevator according to the environmental parameters, it can also be further judged in combination with the number of destination floors registered in the goods transportation call registration information. For example, in the case of no goods, the number of registered destination floors usually matches the travel needs of passengers in the building, such as employees commuting to and from work, residents going home, etc. However, when there are goods in the car, the number of destination floors may increase because the goods need to be delivered to different floors. Based on this and combined with the environmental parameters, it can be more accurately judged whether there are goods inside the first elevator.

[0078] S406. When it is determined that there are goods inside the first elevator, control the first elevator to execute the dedicated direct mode for goods transportation; the first elevator directly reaches the goods transportation destination floor in the dedicated direct mode for goods transportation.

[0079] Exemplarily, when it is determined that there are goods inside the first elevator, control the first elevator to directly reach the goods transportation destination floor, and during the transportation process, the first elevator does not respond to other elevator usage demands, avoiding stopping at other floors due to other passengers' demands during the goods transportation process, thereby reducing the transportation time and improving the transportation efficiency. Further, it avoids passengers and goods being in the same elevator, enhancing the passengers' riding experience.

[0080] In an exemplary embodiment, the method further includes:

[0081] S408. When it is determined that there is no cargo in the first elevator, control the first elevator to execute the passenger mode. The call response priority of the first elevator in the passenger mode is equal to that of the second elevator. The call response priority is used to characterize the response speed to other elevator usage requirements except for the demand for freight elevators and the predicted elevator usage requirements.

[0082] Exemplarily, determining that there is no cargo in the first elevator indicates that when passengers do not actually need to transport goods and, for the sake of convenience, they use the method described in the above embodiment to call the first elevator by long-pressing the floor button to input the freight call registration information. In this case, control the first elevator to enter the passenger mode so that the first elevator provides normal passenger transportation services in the elevator group like the second elevator, making the regulation of the elevator group more reasonable.

[0083] In an exemplary embodiment, the operating state information includes the call registration information of each floor station, the destination floor station registration information of each elevator, the position of each elevator, and the load of each elevator. According to the current operating state information, determine whether the second elevator meets other elevator usage requirements except for the demand for freight elevators in the current elevator usage requirements and the predicted elevator usage requirements, including:

[0084] S502. According to the call registration information of each floor station and the destination floor station registration information of each elevator, determine other elevator usage requirements except for the demand for freight elevators in the current elevator usage requirements and the predicted elevator usage requirements.

[0085] Among them, the call registration information of each floor station may refer to the elevator usage requirement call stations registered through the waiting halls on each floor in the building, and the destination floor station registration information of each elevator may refer to the destination floor stations corresponding one by one to the elevator usage requirement call stations.

[0086] Exemplarily, through the elevator usage requirement call stations and the destination floor stations, other elevator usage requirements except for the demand for freight elevators in the current elevator usage requirements can be obtained, and on this basis, the predicted elevator usage requirements can be obtained.

[0087] S504. According to the position of each elevator, the load of each elevator, and the destination floor station registration information of each elevator, determine whether the second elevator meets other elevator usage requirements except for the demand for freight elevators in the current elevator usage requirements and the predicted elevator usage requirements.

[0088] Exemplarily, through the positions of each elevator, it can be known which floor each elevator is currently on, or whether each elevator is on the way to a certain floor. By combining the load of each elevator and the registration information of the destination floor of each elevator, it is further possible to calculate whether the transportation capacity of the second elevator meets other elevator usage requirements except for the freight elevator usage requirements, and to predict the elevator usage requirements. For example, if an elevator already has a clear destination floor, then when calculating the transportation capacity of the second elevator, this destination needs to be considered to avoid conflicts with the current elevator call requirements. If an elevator is already on the way to a certain floor, then it cannot respond to other elevator call requirements during this period. Understanding the registration information of the destination floor of the elevator car can help the system optimize scheduling. If the destination of a certain elevator is the same as or close to the destinations of some elevator call requirements, then these elevator call requirements can be preferentially considered for allocation to this elevator to improve the operating efficiency of the system.

[0089] Based on the positions of each elevator, the load of each elevator, and the registration information of the destination floor of each elevator, it is possible to more accurately determine whether the second elevator meets other elevator usage requirements except for the freight elevator usage requirements, and to predict the elevator usage requirements.

[0090] In an exemplary embodiment, the freight elevator call registration information includes the destination floor for freight transportation, and the operating status information includes the positions of each freight elevator. Determining the first elevator according to the freight elevator call registration information and the current operating status information includes:

[0091] S602. Calculate the transportation time for each freight elevator to reach the destination floor for freight transportation based on the destination floor for freight transportation and the positions of each freight elevator.

[0092] S604. Determine the freight elevator with the shortest transportation time as the first elevator.

[0093] Exemplarily, based on the destination floor for freight transportation and the positions of each freight elevator, the relative distance between the destination floor for freight transportation and the positions of each freight elevator can be determined. When the moving speeds of the freight elevators are the same, the required time for each freight elevator to reach the destination floor for freight transportation can be calculated, and the freight elevator with the shortest required time is selected as the first elevator to minimize the time required for freight transportation, thereby improving the overall efficiency.

[0094] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this document, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or in turn with at least a part of other steps or steps or stages in other steps.

[0095] Based on the same inventive concept, an embodiment of the present application further provides an elevator group control device for implementing the elevator group control method described above. The solution provided by this device to solve the problem is similar to the solution described in the above method.
