Description

Large and small lift group and method for dispatching elevator according to waiting person information

TECHNICAL FIELD The present invention relates to an optimized configuration and scheduling method for an elevator group. In particular, the present invention relates to a group of elevator groups having different carrying capacities, and a scheduling method thereof based on the number of waiting persons.

BACKGROUND OF THE INVENTION Conventional elevator call buttons are typically located on either side of an elevator door in an elevator car. The buttons on each floor elevator have only the "up" and "down" buttons. In this paper, the term elevator is equivalent to an elevator. The upper part of Figure 1 shows the distribution of the common elevator control buttons. The call information obtained by the control panels on different floors of the elevator car is transmitted to the elevator control system respectively; the call information obtained by the control panel in the elevator car is also transmitted to the elevator control system. The elevator control system uses this information to schedule elevators or elevator groups within its jurisdiction. In this mode of operation, the person calling the elevator tells the elevator to control the amount of information of the dispatching system to be extremely incomplete. For the elevator group running in the network, because the elevator dispatching system does not know more important information of the caller and the waiter, and can not distinguish whether there are several different same-directional calls on a certain floor, it is impossible to know each call. The detailed information of the corresponding transportation operation. Based on the above facts and reasons, when people design multiple elevators in the building, all the same passenger elevators are usually of the same specification. Of course, we do not rule out the setting of different sizes of elevators due to other factors; for example: the difference in capacity between passenger elevators and freight elevators; the difference in capacity between public passenger elevators and dedicated passenger elevators. This artificially set capacity difference is based on the distinction made by different carriers. When we discuss a group of elevators managed by the same elevator control I dispatch system, the reasonable basis for the use of elevators with different specifications is: 1) Which elevator can be manually selected by the elevator manager; 2) Peaks and valleys according to the time period difference. Thus, as shown in the lower part of Fig. 1, the specifications of the elevators A, B, and C are identical. Figure 2 illustrates, by way of example, the problems with existing elevator calling methods. Suppose there are 5 groups of passengers who need to use the elevator (the passenger group is represented by the call number): Passenger group (31), 1 person, on the 2nd floor, the destination floor is 0, press the up button;

Passenger group (32), 2 people, on the 0th floor, the destination floor is 10, press the up button first; at the same time, in order to get the elevator down as soon as possible, press the down button again.

Passenger group (33), 4 people, on the 0th floor, the destination floor is 6, no operation; Passenger group (34), 2 people, on the 0th floor, the destination floor is 12, and the up button is pressed a few times. Passenger group (35), 5 people, on the 5th floor, the destination floor is 7, press the up button. For the elevator control system, the information it knows is that there are people on the 3, 0, and 5 floors to go up; on the 0th floor, someone has to go down. In fact, in this example, the elevator control system cannot know the 0th floor in advance and no one wants to go down. This so-called passenger group (32') does not exist; the elevator control system does not know whether the passenger groups 33, 34 exist. If we use matrix diagrams to express the information obtained by the elevator control system, as shown in Figure 3, the elevator control system only gets calls from callers 31, 32, 32' and 35; for the destination of these calls, The number of people is unaware of the fact that the callers 33 and 34 are inconsistent with the departure floor and direction of travel of the caller 32. Moreover, assuming that the load capacity of the elevator is 8 (as shown in Fig. 3), the elevator control system cannot predict in advance at all, and after the callers 32, 33, and 34 enter the elevator, the caller 35 waiting at the 5th floor cannot. Enter the elevator. Worse, the caller 35 waiting on the 5th floor can only call the next elevator after waiting for the elevator to leave the 5th floor; however, the next elevator coming up may still not meet the needs of the caller 35. . Obviously, if the elevator control system can know all the important information of each call in advance, then an effective scheduling can be made in advance. Figure 4 shows a matrix diagram of the elevator control system knowing all the travel information for each call. In the picture, each call The fortune represented by (31, 32, 33, 34, 35) is accurately mapped to the elevator load capacity matrix. Then the elevator control system can predict in advance that the call 35 is not fully responsive by the elevator in the figure: 3 of the 5 companions have no way to enter the elevator. Of course, while making this judgment, the elevator control system can immediately arrange other elevators to respond to the call.

SUMMARY OF THE INVENTION Several devices in which a caller has a caller number input function, and a method of waiting for a person to input and display are disclosed in the international patent application PCT/IB2014/064694, which is incorporated herein by reference. Based on this concept, the present application further proposes a method for how the elevator group of different carrying capacity uses the waiting number information to perform scheduling. I. Elevator Groups with Different Carrying Capacity The lift group with different carrying capacity proposed by the present invention is under the jurisdiction of the same elevator control/dispatching system. The call system of the elevator group includes a mechanism for the caller to input the waiting number. A call panel is provided in the elevator car, and the elevator control system acquires a call request through a set of call systems. Figure 5 shows the basic structure of the present invention. The three lifts A, B, and C have small, medium, and large sizes (C _A , C _B , C _c ) according to different capacity (Capacity). The control panel shown in the upper part of Figure 5 is located in the elevator car and has the function of inputting the number of peers for each destination floor. You can enter the number of people by clicking the "Ten" button behind the destination floor number. The elevator group of the specification can maintain the same overall load capacity compared with the conventional elevator group of the same specification. The flexibility is greatly improved.

When the ratio between C _A , C _B and C _c is 2: 3: 4, the total bearing capacity of the elevator group of the C _B is the same as the total carrying capacity of the C _B. As shown in Figure 6, if the total load capacity of the above three elevators is: 15 X 3 = 45; the following three large, medium and small The total load capacity of the elevator is: 10 10 15 10 20 = 45; no change. However, the change of this specification brings obvious benefits: the elevator control system can analyze and judge which type of elevator is more suitable according to the call containing the number of people on each floor; if an elevator cannot complete the task, then which one should be sent Two or more elevators, and which calls each should bear. Obviously, small elevators save power compared to large elevators. For elevator groups with only two carrying capacities (C _A , C _B ), the recommended range of C _A / C _B is:

Figure 7 shows the overall load capacity matrix of elevators of both A and B specifications. Figure 8 shows the vector map corresponding to the calls that appear on each floor over time. The so-called vector run is a complete task that contains information on direction, starting floor, destination floor, and number of people; it is represented by a rectangle with a direction in the matrix diagram. In the figure, 71, 72, 73 and 74 represent the upward call (transit); 81, 82, 83 and 84 represent the downward call (transit). The width of each rectangle represents the number of peers. Then, the scheduling of the elevator groups having different carrying capacities is to assign the respective calls (vector operations) in Fig. 8 to the respective elevators in the elevator group to respond. Figure 9 shows an example of allocation. Elevator A with a relatively small carrying capacity is very satisfactory for four calls 71, 72, 73, 74; and Elevator B with a relatively large carrying capacity specifically responds to call 75 (1 1 person goes from Layer 2 to Layer 9 together). Regarding the mechanism for the caller to enter the waiting number included in the call system of the elevator group, one of the following can be used:

1) Enter the “ten” and “one” buttons on the control panel of the elevator to input the number of people;

2) Use the “ 0” to “ 9” number buttons on the control panel of the elevator to enter the number of people;

3) Using the sliding touchpad, select the number of people from the preset database;

4) Using the wireless receiving device installed in the building, the elevator caller inputs the number of people information through mobile terminals such as smart phones and tablet computers. The details are described in the following embodiments by way of specific embodiments. Second, according to the information on the number of waiting persons, the basic principles of dispatching elevators are two extremes: Time priority principle: all available elevators are mobilized to share the response to each call; the energy consumption is high in this mode; but it is suitable for the peak of elevator use. Time period. Energy priority principle: Respond to all call requests with as few elevators as possible, in the extreme case only a small elevator. This principle is suitable for elevator users who are very rare. Time energy balance priority algorithm: You can choose one of the above two principles to perform according to your needs, and most actual scheduling should choose a balance between these two principles: Time and energy consumption should be considered. A power consumption priority scheduling scheme is as follows: (assuming there are three sizes of standby air elevators in large, medium and small sizes)

1) First determine if a small elevator is competent to respond to all calls; if not, then

2) Determine if the elevator in one part is competent to respond to all calls; if not, then

3) Determine if a large elevator is competent to respond to all calls; if not, then

4) Determine if the two small elevators are competent to respond to all calls; if not, then

5) Determine whether two elevators in a small one can handle all calls; if not, 6) continue to select a combination with a larger total load capacity... In fact, in the normal operation of the elevator group, the position of each elevator runs. The direction, the tasks assigned to bear, the expected available load, and the data are dynamically changing. Then the core of this scheduling method is to analyze these factors comprehensively according to the preset time energy balance prioritization algorithm, and select one optimization scheme from all feasible dispatching schemes. The "expected available load capacity" herein refers to the amount of load that is expected to be available when an alternative elevator arrives at each call floor. The elevator group scheduling method according to the waiting number information of the present invention is characterized in that the elevator group includes elevators with different carrying capacity specifications; the elevator group consists of a unified elevator control system To schedule, the call system of the elevator group includes a mechanism for the caller of each floor to input the waiting number. The scheduling method is:

1) matching the vector operation information corresponding to the call request from each floor acquired by the elevator control system through the calling system, by filtering and arranging the combination, and matching the expected available carrying capacity of each elevator in the "shared" state to obtain one a range of possible matching solutions;

2) The elevator control system selects an optimal solution from all the above feasible matching schemes according to a preset time energy consumption prioritization algorithm;

3) When a new call occurs, repeat steps 1) and 2) above. The so-called "shared" state is the "non-exclusive" state. When an elevator is in a position other than "exclusive request" that can respond to its service floor, it is in a "shared" state.

The "shared" state is a typical normal operating state.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a schematic diagram of a common elevator control mode and a lift group. Figure 2 illustrates, by way of example, the problems with existing elevator calling methods. In the figure, the passenger group (31, 32, 33, 34, 35) adopts the existing elevator call mode, and only a small amount of information (including ambiguity information) can be transmitted to the elevator control system. Figure 3 uses a matrix diagram to express the information obtained by the elevator control system. Figure 4 shows a matrix diagram of the elevator control system knowing all vector travel information for each call. Figure 5 shows the basic structure of the present invention. The three lifts, B, and C shown below have three sizes of large, medium, and small according to different capacity; the upper part shows the control panel located in the elevator. Figure 6 shows a comparison of three elevators of the same specification and three elevators of different specifications under the premise that the overall load capacity remains unchanged. Figure 7 shows the overall load capacity matrix for two sizes of elevators (A, B). Figure 8 shows the travel (vector) map corresponding to the calls that appear on each floor over time. In the figure, 71, 72, 73 and 74 represent upward calls; 81, 82, 83 and 84 represent downward calls. The width of each rectangle represents the number of peers. Figure 9 shows an example of a call distribution. Elevator A is responsible for four calls 71, 72, 73, 74; and Elevator B is dedicated to responding to call 75 (1 1 person together from 2nd to 9th floor). Figure 10. Elevator call control panel with "exclusive request" function. Figure 1 1. An elevator call panel with elevators of different sizes that can be "exclusively requested". Among them, the floor and the number of people use the sliding touch input method. There are five data display bits (5001, 5002, 5003, 5004 and 5005) on the touchpad 5000; the "exclusive request" can be implemented by two buttons (91, 92) that distinguish the size of the elevator.

Embodiment 1 Embodiment Example of Inputting Waiting Persons by Using "Ten""Button" FIG. 5 is an embodiment of a large, medium and small elevator group call scheduling having a waiting person input function. On the call panel, corresponding to each destination The floor (of course not including the caller's floor) has a set of input buttons and waiting area display area containing the "ten" and "one"buttons; the caller only needs to point to the "ten" or "one" corresponding to the destination floor. "Button, you can add or subtract the number of waiting people; for the caller on floor 2 (restaurant floor), if the floor to go is 5, you only need to click the "ten" button corresponding to floor number 5, you can register one Waiter; and the corresponding display area will add "1". Similarly, by clicking the "one" button corresponding to floor number 5, you can reduce one waiter, and the corresponding display area will be reduced by "1". The minimum number of waiting persons is "0". In this embodiment, there is a special "exclusive request" button behind the floor number of the caller. In the system, there is an interface that can receive "exclusive requests". When the caller selects the "exclusive request", the elevator control system selects an elevator that meets the demand from the three large, medium and small elevators and withdraws it from the "shared" elevator pool until it completes the exclusive request task. In general, in order to save elevator resources, priority should be given to assigning small elevators to respond to "exclusive requests." Of course, since the elevator has a higher attendance rate, it is also possible to use a set elevator or a large elevator as a priority. If necessary, a method can be provided to make the "exclusive request" caller available to select the size of the elevator.

Embodiment 2 Embodiment of Digital Keyboard Type Number Entry In this embodiment, as shown in FIG. 10, the information acquisition input method includes both a conventional numeric keypad type button "0" - "9" and "OK". (OK) and "C" (Cancel) buttons. At the same time, the panel also includes a special call button 80 or an "exclusive request" sensing area such as "exclusive request". In addition, other special buttons, such as "big items", can be considered to meet special needs. Based on the above embodiment, an information feedback area can be added, as shown in Fig. 10 below. This information feedback area is located next to the "exclusive request" button or the "exclusive request" sensing area. This information comes from the feedback of the elevator control I scheduling system: according to the still valid call request of all callers on each floor, and the current elevators of each elevator. Running the status data, a dispatch schedule is sent to inform which elevator to pick up the current caller and give an expected value of the waiting time. Of course, callers who make "exclusive requests" will also get this feedback.

Embodiment 3: The implementation of the sliding touch type input mode is as shown in FIG. 11. The touchpad, that is, the alternative data selection area 5000, has five candidate data arranged in sequence; wherein the data can be touched. Clicking, by sliding up and down the touch, the data in the candidate data selection area can be smoothly shifted downward or upward in sequence, and the candidate data selection area 5000 is like a display window, from a preset candidate database. A part of the data is presented. There are two groups of alternative databases: a floor candidate database, a database of occupancy numbers. To facilitate the different needs of the exclusive requesting caller, in this embodiment, we have added two "exclusive requests" call buttons: "Large Elevator" 91, "Small Elevator" 92. It should be noted that if multiple elevators running in network operation are segmented, it is necessary to input the destination floor information at the same time as the exclusive request is issued, so that the elevator control system can arrange the elevator that can reach that floor to respond to the exclusive. request. The term "simultaneously" as used herein means that two related operations occur before and after the time difference is short.

Embodiment 4: Entering the number of people using the mobile device. The embodiment uses the mobile terminal device to input the number of people. It is necessary to set up wireless receiving devices such as WI-FI and Bluetooth in the building. The number of people input by the elevator caller through mobile terminals such as smart phones and tablet computers. information. The input interfaces on these mobile terminals can be designed to take full advantage of the convenience of touch operations on mobile devices. Of course, after receiving the call information from the mobile terminal, the elevator control system will promptly feedback the information of the elevator allocation and waiting time to the caller.
