Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more specifically to a method for registering elevator call signals. Background Technology

[0002] Currently, many elevator systems offer passengers remote elevator calling systems. For example:

[0003] The method in the intelligent building system proposed in Document 1 (authorization number CN 107000971 B) includes: establishing a proximity environment relative to elevators within the building; detecting the location of a user device within the proximity environment; determining, by a processor, a source floor and a destination floor corresponding to the user device by accessing user preferences corresponding to the user device, the user preferences indicating the source floor and the destination floor; and generating an elevator call for the elevator by the processor based on the source floor and the destination floor after the proximity system detects that the user device is within a predetermined distance from the elevator, the elevator call being either an immediate elevator call or a delayed elevator call based on the proximity of the user device to the elevator. Essentially, this method determines whether to register an elevator call signal immediately or with a delay based on the distance between the passenger and the elevator.

[0004] Reference 2 (CN201811540194.9) proposes that a smart door lock generates a user's departure signal, which is sent to a cloud server via a smart gateway. The cloud server then generates an elevator call signal based on this signal and sends it to the elevator control system. The elevator control system then uses this call signal to direct the elevator to the user's floor, thereby reducing or eliminating the user's waiting time. Essentially, this solution utilizes the call signal generated by the door lock to achieve remote elevator call signal registration.

[0005] In existing technologies, including the aforementioned literature, a remote elevator calling device is used to generate an elevator calling signal and register the signal before the passenger arrives at the elevator lobby. This ensures that the elevator arrives just in time to the passenger, thus shortening the passenger's waiting time. These existing solutions are all implemented from the perspective of reducing passenger waiting time. However, while these solutions can shorten passenger waiting time to a certain extent, they may lead to reduced elevator operating efficiency and increased energy consumption in certain situations. For example, at time k0, the elevator car is on standby on the 1st floor; at time k1, the first passenger registers an upward call signal to the 8th floor (destination floor is the 15th floor) using their mobile phone. The time required for the first passenger to move to the elevator lobby is approximately 10 seconds, while the time for the first elevator car to move from the 1st floor to the 8th floor is approximately 30 seconds. Since the first elevator car's moving time is longer than the first passenger's moving time, in order to shorten the waiting time as much as possible... During a passenger's waiting time, the first passenger's mobile phone sends a call signal to the elevator control system immediately after the passenger registers the call signal. Upon receiving the call signal from the first passenger's mobile phone, the elevator control system controls the elevator car to move from the 1st floor to the 8th floor. At time k2 (=k1+6 seconds), the elevator car has passed the 2nd floor and continues to move towards the 3rd floor. At this time, the second passenger registers an upward call signal on the 2nd floor using their mobile phone (the destination floor is the 18th floor) and arrives at the waiting hall 5 seconds later. Since the elevator car has already passed the 2nd floor or even the 3rd floor, the elevator car will continue to go up to the 8th floor and return to the 2nd floor to serve the second passenger after completing the first passenger's journey. Clearly, if the first passenger's call signal could be delayed until k1+x (e.g., x=8, as long as the elevator car hasn't passed the second passenger's departure floor, or further, hasn't passed the deceleration point relative to the second passenger's departure floor) before being sent to the elevator control system, the elevator car could first stop at the 2nd floor to allow the second passenger to enter, then stop at the 8th floor for the first passenger to enter, then stop at the 15th floor for the first passenger to disembark, and finally stop at the 18th floor for the second passenger to disembark, thus completing the service for both passengers. Obviously, compared to existing technical solutions, in the latter method, although the first passenger's waiting time is extended, the second passenger's waiting time is significantly shortened, and the overall service efficiency and energy consumption of the elevator are significantly improved. Of course, even if the first passenger's waiting signal is delayed and sent to the elevator drive control system but the second passenger hasn't arrived, the first passenger's waiting time will not exceed the waiting time of the traditional call signal registration method (registering the call signal using the up / down registration buttons after arriving at the elevator lobby), and the elevator's operating efficiency and energy consumption will not increase. Therefore, how to improve the overall transportation efficiency and reduce the overall operating energy consumption of elevators by appropriately delaying the transmission time of off-site registered elevator call signals to the elevator control system has become a technical problem to be solved.

[0006] The delay in the prior art is only to ensure that the elevator car does not arrive at the departure floor before the passenger arrives at the waiting hall. For example, if the time required for the elevator to move from its current position to the first passenger's departure floor is only 5 seconds, while the time required for the first passenger to move from its current position to the elevator hall is 9 seconds, then at least 4 seconds is delayed before sending the first passenger's call signal to the elevator drive system in order to avoid the elevator waiting time at the departure floor, rather than in this application to take into account the elevator's ability to transport a possible second passenger. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides an elevator call signal registration method, comprising:

[0008] Step S1: Determine whether a new remote elevator call signal and its passenger movement information have been received. The passenger movement information includes the passenger movement time required for the passenger to move from its current position to the elevator waiting hall or the distance between the passenger's current position and the elevator waiting hall. If yes, proceed to the next step; otherwise, proceed to step S5.

[0009] Step S2: Obtain elevator operation information, which includes at least the current position of the elevator car and the current direction of travel;

[0010] Step S3: Determine whether the direction of the new remote elevator call signal is opposite to the current direction of elevator operation or whether the departure floor of the new remote elevator call signal is located on the opposite side of the current position of the elevator car relative to the current direction of elevator operation. If so, mark the new remote elevator call signal as an elevator call signal to be processed and proceed to step S5; otherwise, proceed to the next step.

[0011] Step S4: Determine whether there is at least one specific floor between the departure floor of the new remote call signal and the current position of the elevator car. If so, send the new remote call signal to the elevator control system in a delayed sending mode to complete the registration of the new call signal; otherwise, send the new remote call signal to the elevator control system in an immediate sending mode to complete the registration of the new call signal. The delayed sending mode refers to sending the new remote call signal to the elevator control system after a certain delay time; the immediate sending mode refers to sending the new remote call signal to the elevator control system immediately. The specific floor refers to a floor that meets the following conditions:

[0012] Condition A is the floor where the elevator car can stop;

[0013] Condition B: If there is no registered call signal with the same direction of travel as the elevator's current direction of travel, use it as the departure floor;

[0014] Step S5: Determine whether the elevator has completed the response to all remote call signals with the confirmed sending time. If yes, proceed to the next step; otherwise, return to step S1.

[0015] Step S6: Based on the elevator operation information, the specific pending elevator call signal, and its passenger movement information, select one of the immediate sending mode and the delayed sending mode as the selected sending mode, and send the specific pending elevator call signal to the elevator control system according to the selected sending mode to complete the registration of the specific pending elevator call signal. Return to step S1. The specific pending elevator call signal refers to the pending elevator call signal in which the passenger's elevator travel direction is opposite to the elevator's running direction when it completes the response to all remote elevator call signals with the determined sending time.

[0016] Preferably, step S4 determines the delay time and the sending time based on the new remote elevator call signal, its passenger movement information, and elevator operation information.

[0017] Preferably, in step S4, the elevator operation information is used to determine whether there is an elevator call signal that has not yet been responded to. If there is, the sending time is determined based on the relative position of the departure floor of the new remote call signal with respect to the departure floor or destination floor of the elevator call signal that has not yet been responded to. If there is no such call signal, the delay time and the sending time are determined based on the current position of the elevator car and the departure floor of the new remote call signal.

[0018] Preferably, the sending time satisfies the following conditions: Condition 1, the time when the elevator car moves from its current floor to the passenger's departure floor under the control of the elevator control system is not earlier than the time when the passenger moves to the elevator waiting hall; Condition 2, the time when the elevator starts moving from its current floor to the passenger's departure floor under the control of the elevator control system is not later than the time when the passenger moves.

[0019] Preferably, step S4 sets the transmission time such that the delay time T between the reception time (when the remote elevator call signal is received) and the transmission time (when the transmission time is determined in step S1) is such that... delay Satisfy T min <T delay ≤T max To ensure that conditions 1 and 2 are met, where T min T is the time difference between the passenger's travel time and the time required for the elevator to travel from its current position to the passenger's departure floor. max For passenger travel time.

[0020] Preferably, when step S4 determines that there are no call signals that have not yet completed their response, the delay time and the sending time are determined in any of the following ways:

[0021] Method 1: By setting the delay time T delay =T max This allows for consideration of potential second call signals.

[0022] Method 2: The delay time is determined based on the number of floors that can be stopped between the departure floor of the new remote call signal and the current location of the elevator car. The more floors that can be stopped between the departure floor of the new remote call signal and the current location of the elevator car, the longer the delay time.

[0023] Method 3: By determining the delay time, the delay time is related to T. max The ratio is equal to the ratio of the number of floors that can be stopped between the departure floor of the new remote call signal and the current location of the elevator car to the total number of floors that can be stopped in the building.

[0024] Method 4: Based on historical data of elevator call signals, determine the time when the new remote elevator call signal was received in step S1 and the time T elapsed from the determined time. max The second call signals that occur between the obtained times are statistically analyzed, and the sending time is determined based on the statistical results.

[0025] This invention rationally sets the timing of when passengers' remote elevator call signals are sent to the elevator control system. This allows the elevator to accommodate the transportation needs of other passengers traveling in the same direction (i.e., combined transportation of passengers from different departure floors), thereby improving the overall transportation efficiency of the elevator and reducing its overall operating energy consumption.

It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0029] Example 1

[0030] like Figure 1 As shown, this embodiment provides an elevator call signal method, including:

[0031] Step S1: Determine whether a new remote elevator call signal and its passenger movement information have been received. The passenger movement information includes the passenger movement time required for the passenger to move from its current position to the elevator waiting hall or the distance between the passenger's current position and the elevator waiting hall. If yes, proceed to the next step; otherwise, proceed to step S5.

[0032] Step S2: Obtain elevator operation information, which includes at least the current position of the elevator car and the current direction of travel;

[0033] Step S3: Determine whether the direction of the new remote elevator call signal is opposite to the current direction of elevator operation or whether the departure floor of the new remote elevator call signal is located on the opposite side of the current position of the elevator car relative to the current direction of elevator operation. If so, mark the new remote elevator call signal as an elevator call signal to be processed and proceed to step S5; otherwise, proceed to the next step.

[0034] Step S4: Determine whether there is at least one specific floor between the departure floor of the new remote call signal and the current position of the elevator car. If so, send the new remote call signal to the elevator control system in a delayed sending mode to complete the registration of the new call signal; otherwise, send the new remote call signal to the elevator control system in an immediate sending mode to complete the registration of the new call signal. The delayed sending mode refers to sending the new remote call signal to the elevator control system after a certain delay time; the immediate sending mode refers to sending the new remote call signal to the elevator control system immediately. The specific floor refers to a floor that meets the following conditions:

[0035] Condition A is the floor where the elevator car can stop;

[0036] Condition B: If there is no registered call signal with the same direction of travel as the elevator's current direction of travel, use it as the departure floor;

[0037] Step S5: Determine whether the elevator has completed the response to all remote call signals with the determined sending time (here, response means that the elevator has completed the transportation of passengers to the call signals). If yes, proceed to the next step; otherwise, return to step S1.

[0038] Step S6: Based on the elevator operation information, the specific pending elevator call signal, and its passenger movement information, select one of the immediate sending mode and the delayed sending mode as the selected sending mode, and send the specific pending elevator call signal to the elevator control system according to the selected sending mode to complete the registration of the specific pending elevator call signal. Return to step S1. The specific pending elevator call signal refers to the pending elevator call signal in which the passenger's elevator travel direction is opposite to the elevator's running direction when it completes the response to all remote elevator call signals with the determined sending time.

[0039] It should be noted that a remote elevator call signal is an elevator request signal registered by a passenger using a remote elevator call signal registration device (such as a mobile terminal, smartwatch, or the smart home device described in Document 2). The remote elevator call signal includes information about the direction of travel, the departure floor, and the destination floor.

[0040] Passenger movement information includes the passenger movement time required for a passenger to move from their current location to the elevator lobby or the distance between the passenger's current location and the elevator lobby; when the passenger movement information is the distance between the passenger's current location and the elevator lobby, the passenger movement time can be estimated based on the speed of distance change.

[0041] To ensure that the elevator car travels from its current floor to the passenger's departure floor no earlier than the passenger arrives at the elevator (otherwise, the elevator would wait for the passenger at the departure floor, which is generally avoided to improve elevator efficiency, except for VIP services), the elevator's travel time needs to be estimated based on the elevator car's current position and the passenger's destination floor. If the passenger's travel time is no greater than the elevator's travel time, existing technology typically registers the call signal immediately and sends it to the elevator control system. The elevator control system then controls the elevator car to immediately move from its current position to the passenger's departure floor. When the elevator car arrives at the departure floor, the passenger has already arrived at the elevator and can then enter the car. If the passenger's travel time is greater than the elevator's travel time, existing technology typically delays the time difference (the passenger's travel time minus the elevator's travel time) before sending the call signal to the elevator control system. The elevator control system then controls the elevator car to immediately move from its current position to the passenger's departure floor. The above-mentioned methods in existing technology aim to minimize the passenger's waiting time. As described in the background section, this approach is not ideal in certain scenarios (primarily when a call signal arrives slightly later than the passenger's call signal between the current position of the elevator car and the passenger's destination floor). In reality, under normal circumstances, passengers are not particularly sensitive to waiting times (unless the waiting time exceeds a certain threshold, such as extremely long waiting times during peak hours), and are not very sensitive to the reduction in waiting time achieved through pre-registered call signals. Therefore, it is sufficient to ensure that the call signal registration is completed by the time the passenger arrives at the elevator (here, "complete call signal registration" means informing the passenger at the floor in a certain way (such as illuminating the up or down buttons for the corresponding direction) or through the passenger's registration device that their call signal has been received and registered).

[0042] In this embodiment, step S4 determines the delay time and the sending time based on the new remote elevator call signal, its passenger movement information, and elevator operation information.

[0043] Step S4 determines whether there are any call signals that have not yet been responded to based on the elevator operation information. If there are, the sending time is determined based on the relative position of the departure floor of the new remote call signal with respect to the departure floor or destination floor of the call signal that has not yet been responded to. If there are no, the delay time and the sending time are determined based on the current position of the elevator car and the departure floor of the new remote call signal.

[0044] The transmission time satisfies the following condition:

[0045] Condition 1: The time when the elevator car moves from its current floor to the passenger's departure floor under the control of the elevator control system is no earlier than the time when the passenger moves to the elevator waiting hall.

[0046] Condition 2: The elevator, under the control of the elevator control system, begins its movement from its current floor to the passenger's departure floor at a time no later than the passenger's departure time.

[0047] Step S4 sets the transmission time such that the delay time T between the reception time (determined in step S1) and the transmission time (determined in step S1) when the remote elevator call signal is received is set. delay Satisfy T min <T delay ≤T max To ensure that conditions 1 and 2 are met, where T min T is the time difference between the passenger's travel time and the time required for the elevator to travel from its current position to the passenger's departure floor. max For passenger travel time.

[0048] In order to accommodate multiple possible remote elevator call signals, the remote elevator call signal in this embodiment also includes a second elevator call signal, which refers to a remote elevator call signal that meets the following conditions;

[0049] Condition 1: The second call signal occurs at a time that falls between the determined time and an interval T elapsed from the determined time. max Between the corresponding times;

[0050] Condition 2: The departure floor of the second call signal is located between the current position of the elevator car and the first departure floor corresponding to the new remote call signal;

[0051] Condition 3: The direction of the second elevator call signal is consistent with the direction of the new remote elevator call signal.

[0052] When step S4 determines that there are no elevator call signals that have not yet completed their response, the delay time and the sending time shall be determined in any of the following ways:

[0053] Method 1: By setting the delay time T delay =T max This allows for consideration of potential second call signals.

[0054] Method 2: The delay time is determined based on the number of floors that can be stopped between the departure floor of the new remote call signal and the current location of the elevator car. The more floors that can be stopped between the departure floor of the new remote call signal and the current location of the elevator car, the longer the delay time.

[0055] Method 3: By determining the delay time, the delay time is related to T. max The ratio is equal to the ratio of the number of floors that can be stopped between the departure floor of the new remote call signal and the current location of the elevator car to the total number of floors that can be stopped in the building.

[0056] Method 4: Based on historical data of elevator call signals (such as historical data from the previous day, week, or month), determine the time when the new remote elevator call signal was received in step S1 and the time T elapsed since the determined time. max The second call signals that occur between the obtained times are statistically analyzed, and the sending time is determined based on the statistical results.

[0057] Specifically, for method 4, the sending time can be determined based on statistical results using the following methods:

[0058] In method 1, in the fourth step, step S4 calculates the occurrence time of the second elevator call signal between the determined time and T elapsed from the determined time. max The probability density between the determined time and the sent time is obtained, and the sent time makes the probability between the determined time and the sent time greater than a threshold.

[0059] In method 2, in the manner 4, step S4 calculates the probability of the second call signal occurring based on statistical results, and determines the determined time such that the delay time is divided by the determined time and the time elapsed since the determined time T. max The quotient of the time intervals between the obtained moments is equal to the probability.

[0060] In method 3, in the fourth approach, step S4 calculates the probability of the second call signal occurring based on statistical results; when the probability is greater than a preset probability, the transmission time is adjusted to allow a delay time T. delay =T max Otherwise, the delay time T delay =T min .

[0061] Method 4, in which step S4 determines the transmission time as follows:

[0062] Step A1: Calculate the first reduction in waiting time and the second reduction in waiting time; the first reduction in waiting time is the amount by which the waiting time of the first passenger is shortened when the delay time is minimized; the second reduction in waiting time is the difference between the total waiting time for separate transport and the total waiting time for combined transport, wherein the total waiting time for separate transport is the total waiting time for the first passenger and the second passenger when transporting them separately, and the total waiting time for combined transport is the total waiting time for the first passenger and the second passenger when transporting them together.

[0063] Step A2: Calculate the probability α of the second elevator call signal based on the historical data of the elevator call signal. Use the probability α as a weighted average of the reduction in the first waiting time and the reduction in the second waiting time. The weight of the reduction in the first waiting time is 1-α, and the weight of the reduction in the second waiting time is α.

[0064] Step A3: If the weighted reduction in the first waiting time is greater than the weighted reduction in the second waiting time, the delay time is the minimum value; otherwise, the delay time is the maximum value.

[0065] Method 5, in the above method 4, the method for determining the transmission time in step S4 is as follows:

[0066] Step B1: Determine the probability of occurrence of each second call signal at each time point within the range of the delay time based on historical data.

[0067] Step B2: Select the time when the second call signal with the highest probability occurs;

[0068] Step B3, make the delay time slightly longer than the time when the second call signal with the highest probability occurs.

[0069] Method 6, in the manner 4, the method for determining the transmission time in step S4 is as follows:

[0070] Step C1: Determine the probability of occurrence of each second call signal at each time point within the range of the delay time based on historical data.

[0071] Step C2: Select the time when the second call signal with the highest probability occurs;

[0072] Step C3: When the maximum probability is greater than the threshold, make the delay time slightly longer than the time when the second call signal corresponding to the maximum probability occurs; otherwise, make the delay time the minimum value.

[0073] Furthermore, when the elevator is providing transportation services to passengers, when a new remote call signal is received, if step S4 determines that there is no call signal that has not yet been responded to, and if the departure floor of the new remote call signal is at least one destination floor of the passenger in the car or the departure floor of a call signal that has been sent to the elevator control system, then the new remote call signal is sent immediately.

[0074] Otherwise, use the following steps to set an upper limit for the delay time of all remote elevator call signals:

[0075] Step D1: For remote call signals whose departure floor is located in front of the elevator car's current position relative to the elevator's direction of travel and have not yet been sent to the elevator control system, as well as the new remote call signal, calculate the Tmax of each remote call signal.

[0076] Step D2: The remote call signal corresponding to the minimum Tmax is taken as the specific remote call signal;

[0077] Step D3: Set the upper limit of the delay time of the remote call signal between the current location of the elevator car and the departure floor of the specific remote call signal to the minimum Tmax;

[0078] Step D4: Update the current location of the elevator car to the departure floor of the specific remote call signal;

[0079] Step D5, return to step D1, and continue until the upper limit of the delay time for all remote elevator call signals is set.

[0080] After determining the upper limit of the delay time, the transmission time can be further determined using any of the methods described in Methods 1 to 4.

[0081] Step S6 determines the selected transmission mode of the specific call signal to be processed according to the following steps:

[0082] Step S61: Obtain the current elevator running time;

[0083] Step S62: Correct the passenger movement time of the specific elevator call signal to be processed based on the current time (i.e., subtract the time period from the time when the specific elevator call signal to be processed was acquired to the current time from the passenger movement time corresponding to the time when the specific elevator call signal to be processed was acquired, and the difference obtained is the correction result).

[0084] Step S63: Calculate the difference between the corrected passenger travel time for each specific call signal and the travel time required for the elevator to move from its current position to the departure floor of each specific call signal, and use this difference as the maximum value of the delay time for each specific call signal.

[0085] Step S64: Determine the specific elevator call signal to be processed corresponding to the maximum value of the minimum delay time, and take it as the first specific elevator call signal to be processed;

[0086] Step S65: Determine if a second floor exists. The second floor refers to a floor located between the current elevator position and the departure floor of the first specific call signal to be processed, where the elevator car can stop and there is no registered call signal that would be used as the departure floor. If so, proceed to the next step; otherwise...

[0087] Step S66: Determine the third floor that is located in front of the current position of the elevator car relative to the direction of elevator travel and is closest to the current position of the elevator car;

[0088] Step S67: For specific pending elevator call signals whose departure floor is located between the current position of the elevator car and the third floor, adopt the immediate transmission mode; for the remaining specific pending elevator call signals with a delay time, adopt the delayed transmission mode, and uniformly set their delay time to the maximum delay time of the first specific pending elevator call signal.

[0089] After determining the upper limit of the delay time, the transmission time can be further determined using any of the methods described in Methods 1 to 4.
