Description

Technical Field

[0001] This invention relates to the field of elevators, and more specifically to an elevator identification method for disruptive behavior while riding an elevator. Background Technology

[0002] Currently, elevators have become one of the most important vertical transportation tools in buildings, providing up and down transportation services for passengers within the building. Passengers use the up / down registration buttons or destination registration devices located on the floors to provide their departure floor to the elevator, and use the destination registration devices on the floors or inside the car to provide their destination floor to the elevator. The elevator then provides transportation services to passengers based on their departure and destination floors.

[0003] If, during elevator operation, individual passengers (such as mischievous children) use the destination floor registration device to register many unnecessary destination floors in a short period of time out of a prank, it will cause a significant reduction in the elevator's operating efficiency and seriously affect the riding experience of other passengers.

[0004] Regarding this disruptive behavior on elevators, CN201210112434.1 proposes using images inside the elevator car to identify the number of passengers and then determining whether disruptive behavior such as randomly registering destination floors exists based on the relationship between the number of passengers and the number of registered destination floors. CN201310116151.9 proposes obtaining the number of passengers based on their weight and then determining whether disruptive behavior such as randomly registering destination floors exists based on the relationship between the number of passengers and the number of registered destination floors. Both of these solutions are based on the number of passengers and the number of destination floors, and have obvious drawbacks: determining the number of passengers either requires additional equipment (such as cameras, which have a high image recognition processing load) or has low accuracy (e.g., the accuracy of weighing results from weighing devices may have detection errors, and the detection error can be attributed to the unbalanced torque caused by the static friction that inevitably exists when the drive motor is at zero speed). To address this, CN 201911002996.9 proposed that when an elevator stops at consecutive floors without external calls or light curtain activation signals and the number of floors registered for internal calls exceeds the cumulative number of floors the elevator has stopped at consecutively, it should be considered as disruptive behavior. However, this solution requires the use of light curtain signals and has drawbacks such as untimely detection (requiring that the elevator stops at consecutive floors without external calls or light curtain activation signals for a certain number of consecutive floors).

[0005] Thus, how to identify disruptive behavior while riding an elevator in a timely and accurate manner has become a technical problem that needs to be solved. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an elevator identification method that can identify disruptive behavior in a timely and accurate manner.

[0007] To address the aforementioned technical problems, the present invention provides an elevator identification method, the identification method comprising:

[0008] Step S1: Receive destination floor registration information from the destination floor registration device;

[0009] Step S2: Determine the location of the destination floor registration information on the operation interface of the destination floor registration device;

[0010] Step S3: Analyze the expansion trajectory of the destination floor registration information on the two-dimensional plane of the destination floor registration device operation interface in chronological order, based on the registration time corresponding to each destination floor registration information and its position on the destination floor registration device operation interface.

[0011] Step S4: Determine whether the expansion trajectory is regular. If it is, it is considered a disruptive registration operation; otherwise, it is considered a normal registration operation.

[0012] Preferably, in step S1, if the destination floor registration information meets the following destination floor registration conditions, proceed to step S2; otherwise, end the process. Condition 1: Registration is completed within a time window of length T. Condition 2: The number of registrations is ≥ n, where n is a positive integer greater than 2. Condition 3: All registrations originate from the same destination floor registration device.

[0013] Preferably, the registration conditions for the target floor further include: condition 4, where the time interval T0 between the registration times of any two adjacent floor registration information is less than a time threshold.

[0014] Preferably, the destination floor registration device is a shared destination floor registration device for different elevator users to register their destination floors.

[0015] Preferably, the regularity refers to whether the movement of the expansion trajectory presents at least one of the following: a straight line, a broken line, an arc, a parabola, and a continuous, smooth curve with a curvature not exceeding the curvature threshold β.

[0016] Preferably, the expansion trajectory is a directed line segment formed by sequentially connecting the positions of each destination floor registration information on the destination floor registration device operation interface according to the registration time order, with the position of the earliest registered destination floor registration information as the starting point and the position of the last registered destination floor registration information as the ending point.

[0017] Preferably, the registration time and location information corresponding to each destination floor registration information are analyzed to determine whether there are m groups of destination floor registration information with approximately equal numbers, where the time interval between the registration times of the destination floor registration information in each group is significantly smaller than the time interval between different groups, and the positions of each destination floor registration information in the group are adjacent to each other. If so, a directed line segment is formed with the position of the earliest registered group of destination floor registration information as the starting point and the position of the last registered group of destination floor registration information as the ending point, taking the group as the unit.

[0018] Preferably, the ratio of the number of registered destination floors to the number of floors between the current floor of the elevator and the terminal floor in its direction of travel, or the ratio of the number of registered destination floors to the total number of floors the elevator stops at in the building, is greater than a threshold.

[0019] Preferably, before step S1, the following step S0 is also included: Step S0: Determine whether the elevator is in normal operation and / or during non-peak passenger flow periods. If so, proceed to step S1; otherwise, end.

[0020] Preferably, the destination floor registration device is located on the floor station. If no confirmation is received after a preset time after receiving the destination floor information, it is considered a disruptive registration operation.

[0021] Preferably, the destination floor registration device is located inside the elevator car. When the elevator arrives at the earliest destination floor but no passengers disembark, the passenger is prompted to perform a confirmation operation. If no confirmation operation information is received, it is considered as disruptive behavior.

[0022] Another elevator identification method for disruptive behavior provided by this approach includes:

[0023] Step S1: Receive destination floor registration information from the destination floor registration device;

[0024] Step S2: Determine the location of the destination floor registration information on the operation interface of the destination floor registration device;

[0025] Step S3: Analyze the location of the target floor registration information and enumerate all possible regular connection methods;

[0026] Step S4: Determine if there is at least one regular connection method in which the connection order of the target floor registration information is consistent with the order in which the corresponding registration times are formed. If so, it is considered a disruptive registration operation; otherwise, it is considered a normal registration operation.

[0027] Compared with existing technologies, the elevator identification method of the present invention can identify elevators that cause disturbances in a timely and accurate manner. Attached Figure Description

[0028] Figure 1 This is a flowchart of Embodiment 1 of the elevator identification method of the present invention.

[0029] Figure 2 This is a flowchart of Embodiment 2 of the elevator identification method of the present invention. Detailed Implementation

[0030] The embodiments of the present invention are described below with reference to the accompanying drawings and specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Specific details are set forth in the following description to provide a thorough understanding of the present invention; however, the present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be based on different viewpoints and applications. Those skilled in the art can make various similar extensions and substitutions without departing from the spirit of the present invention.

[0031] Example 1: As shown in the attached document Figure 1 As shown, the elevator identification method for disruptive elevator behavior in this embodiment includes the following steps:

[0032] Step S1: Receive destination floor registration information from the destination floor registration device;

[0033] Step S2: Determine the location of the destination floor registration information on the operation interface of the destination floor registration device;

[0034] Step S3: Analyze the expansion trajectory of the destination floor registration information on the two-dimensional plane of the destination floor registration device operation interface in chronological order, based on the registration time corresponding to each destination floor registration information and its position on the destination floor registration device operation interface.

[0035] Step S4: Determine whether the expansion trajectory is regular. If it is, it is considered a disruptive registration operation; otherwise, it is considered a normal registration operation.

[0036] In step S4, the regularity refers to the unique geometric characteristics that the movement trajectory of the operator (such as a fingertip) during the malicious disruption of the registration device on the target floor should possess. Here, the set characteristics refer to the expansion trajectory exhibiting at least one of the following: a straight line, a broken line, an arc, a parabola, or a continuous, smooth curve with a curvature not exceeding the curvature threshold β. Therefore, step S4 should first determine whether the movement trajectory can be completed by a single passenger's fingertip in a short time; secondly, it should determine whether the movement trajectory possesses predetermined unique geometric characteristics. This assumes that the passenger's malicious registration involves rapid, continuous registration operations within a short time and does not continuously change direction.

[0037] The construction of the movement trajectory includes the following two cases:

[0038] Method 1: Passengers maliciously register using a single finger, meaning only one button is registered at a time, generating a destination floor signal. In this case, the expansion trajectory is a directed line segment formed by sequentially connecting the positions of each destination floor registration information on the destination floor registration device's interface according to the registration time, starting from the position of the earliest registered destination floor information and ending at the position of the last registered destination floor information. Here, the width of the movement trajectory is the width of a single destination floor registration signal.

[0039] Method 2 involves passengers maliciously registering using their entire palm. The biggest difference from Method 1 is that the passenger simultaneously operates at least two destination floor buttons at the same time (or within extremely long intervals) and slides their palm to maliciously register. In this case, the method analyzes the registration time and location information corresponding to each destination floor registration, determining if there are approximately m groups of destination floor registration information of roughly equal number. The time interval between registration times of the destination floor registration information in each group is significantly smaller than the time interval between different groups, and the positions of the destination floor registration information within each group are adjacent. If so, a directed line segment is formed, starting from the position of the earliest registered destination floor registration information and ending at the position of the last registered destination floor registration information, and this is used as an expansion trajectory (mainly to address the special disruptive registration scenario of palm-swiping registration). The width of this trajectory is the width of at least two destination floor buttons operated simultaneously at the same time (or within extremely long intervals). The reason for grouping is that passengers use two fingers to simultaneously separate the horizontal distance of the button and then slide it down to register. There will still be a certain time interval between the signals of the two horizontal buttons when registering, but this interval will be significantly shorter than the interval between the components of the two adjacent groups.

[0040] Example 2: As shown in the attached document Figure 2 As shown, the elevator identification method for disruptive elevator behavior in this embodiment includes the following steps:

[0041] Step S1: Receive destination floor registration information from the destination floor registration device;

[0042] Step S2: Determine the location of the destination floor registration information on the operation interface of the destination floor registration device;

[0043] Step S3: Analyze the location of the target floor registration information and enumerate all possible regular connection methods;

[0044] Step S4: Determine if there is at least one regular connection method in which the connection order of the target floor registration information is consistent with the order in which the corresponding registration times are formed. If so, it is considered a disruptive registration operation; otherwise, it is considered a normal registration operation.

[0045] The regularity here is the same as that in Example 1.

[0046] The difference between this embodiment and Embodiment 1 lies in the way the registration time information is utilized. In this embodiment, a trajectory is first drawn based on the location, and then it is checked whether the order of the registration information in the trajectory with unique geometric characteristics conforms to the corresponding registration time order.

[0047] Example 3: This example, based on the previous examples, further restricts the destination floor registration information. In step S1, if the destination floor registration information meets the following destination floor registration conditions, proceed to step S2; otherwise, the process ends.

[0048] Condition 1: Registration must be completed within a time window of length T;

[0049] Condition 2: The quantity is greater than or equal to n, where n is a positive integer greater than 2;

[0050] Condition 3: All devices originate from the same floor unit with the same registration purpose.

[0051] Condition 3 is mainly to prevent signals from different registration destination floor devices from being combined together to satisfy conditions 1 and 2, thus leading to misjudgment.

[0052] Preferably, the destination floor registration device is a shared destination floor registration device for different elevator users to register their destination floors. This is because with passenger-specific destination floor registration devices such as mobile terminals, it is unlikely that a passenger would use their unique device to maliciously register multiple unnecessary elevator requests to cause disruption, as the unique device usually has identification information corresponding to that passenger, making it easy to identify malicious disruptors. Therefore, we do not consider malicious disruptive behavior based on passenger-specific destination floor registration devices.

[0053] Considering that passengers who maliciously disrupt the registration process typically register multiple destination floors quickly and consecutively, we can further require the destination floor registration information to meet the following requirements in addition to the three conditions:

[0054] Condition 4: The time interval T0 between the registration times of any two adjacent destination floor registration information is less than the time threshold.

[0055] This avoids misjudgments in scenarios such as: a passenger registers two destination floors consecutively (the passenger and their companion are going to different destination floors), pauses briefly, and then, at the request of other passengers in the car, registers three more destination floors consecutively. Without this condition, if the passenger's two registrations happen to satisfy conditions 1 and 2 (condition 3 is obviously also satisfied), a misjudgment will occur.

[0056] The above embodiments essentially utilize the characteristics of the registration process for the destination floor registration information to make the judgment.

[0057] Example 4: The elevator identification method for disruptive behavior in this example receives and determines the position of the destination floor registration information on the operation interface of the destination floor registration device, and judges whether the destination floor registration information meets the following conditions:

[0058] 1) Quantity ≥ n;

[0059] 2) The time interval T0 between the registration times of any two adjacent floors is less than the time threshold;

[0060] 3) The ratio of the number of registered destination floors to the number of floors between the current floor of the elevator and the terminal floor in its direction of travel, or the ratio of the number of registered destination floors to the total number of floors the elevator stops at in the building, is greater than a threshold.

[0061] 4) The elevator stops at the earliest registered destination floor (there is no external call signal on that floor) but no passengers enter the car.

[0062] At this point, it is assumed that the passenger maliciously registered and then left the elevator (assuming there is a time interval between the passenger registering their actual destination floor and the prank, and this time interval is greater than a time threshold). Alternatively, if condition 4 is met, it can be determined that the passenger is suspected of maliciously disrupting the registration process, and the passenger can be prompted to perform a confirmation operation. If the confirmation is received, the registration will not be considered maliciously disruptive; if the confirmation is not received, the registration will be considered maliciously disruptive.

[0063] The above refers to the registration of the destination floor inside the elevator car.

[0064] When the destination floor registration device is located on a floor, determine whether the destination floor registration information meets the following conditions:

[0065] 1) Quantity ≥ n;

[0066] 2) The time interval T0 between the registration times of any two adjacent floors is less than the time threshold;

[0067] 3) The ratio of the number of registered destination floors to the number of floors between the current floor of the elevator and the terminal floor in its direction of travel, or the ratio of the number of registered destination floors to the total number of floors the elevator stops at in the building, is greater than a threshold.

[0068] 4) No passengers enter the elevator car when it stops at the floor where the destination floor registration device is located (or after being reminded).

[0069] At this point, it is assumed that the passenger maliciously registered and then left or deliberately did not take the elevator (it would be best to add the condition that the crowding level in the elevator car does not exceed the threshold).

[0070] This embodiment identifies malicious disruptive registration results.

[0071] Of course, the following conditions regarding the registration information for the destination floor can be further added to the above conditions:

[0072] Complete the registration within a time window of length T;

[0073] Quantity ≥ n;

[0074] All of them originated from the same floor unit registered for the same purpose.

[0075] Example 5: If the elevator is running and there is only one destination floor to stop at, and it receives several destination floor registration information in the opposite direction (e.g., the elevator is going up and is on the 8th floor, but it receives several destination floor registration information below the 8th floor), and these destination floor information also meet conditions 1 to 3 in Example 3 (or also meet condition 4), then it is considered to be malicious disruptive registration.

[0076] Example 6: Preferably, the method will only initiate the identification of disruptive behavior when the elevator receives registration information for the destination floor that meets the aforementioned conditions, and there is only one destination floor remaining before the elevator stops. This condition is designed to address the fact that malicious disruptive passengers typically only engage in disruptive behavior when they are the only passengers (or at least strangers) remaining in the elevator car.

[0077] Example 7: Considering that during peak passenger flow periods, most elevator cars will contain passengers traveling together, making malicious disruption unlikely; on the other hand, when the elevator is in an abnormal state (such as during rapid descent / ascent, passengers may engage in actions similar to malicious disruption registration in order to save themselves), this should not be considered malicious disruption registration. Therefore, these two situations should be excluded. Hence, this method includes the following step S0 before step S1:

[0078] Step S0: Determine whether the elevator is in normal operation and / or during non-peak passenger flow periods. If yes, proceed to step S1; otherwise, end.

[0079] The present invention has been described in detail above through specific embodiments. These embodiments are merely preferred embodiments of the present invention, and the present invention is not limited to the above-described implementation methods. Equivalent substitutions and improvements made by those skilled in the art without departing from the principles of the present invention should be considered within the scope of the technology protected by the present invention.
