Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more particularly to a scheduling method, device, electronic equipment, and storage medium. Background Technology

[0002] As society develops, elevator technology is constantly being updated. However, in early buildings, elevators mostly operated independently, in parallel, or in zones. Elevator group control is typically found in high-end commercial buildings and is less common in other buildings.

[0003] Operating modes such as single-elevator operation, parallel operation, multiple elevators divided into single and double floors, and multiple elevators divided into high and low zones are all simple operating methods involving random use or local dispatch. However, over long-term use, as usage time increases, the frequency of use of different elevators will vary. Some elevators may be used far more frequently than others, resulting in greater wear and tear and component aging in these elevators, thus leading to significant lifespan differences among elevators within a building. Summary of the Invention

[0004] This invention provides a scheduling method to solve the problem of large lifespan deviations among different elevators in a building in the prior art.

[0005] In a first aspect, the present invention provides a scheduling method, comprising:

[0006] Obtain historical operating data for multiple elevators in an elevator group;

[0007] For each elevator, a first feature value representing the degree of wear and tear caused by the elevator during each floor stop and a second feature value representing the degree of wear and tear caused by the elevator during operation are extracted from the historical operation data.

[0008] The elevator loss rate at each floor stop is calculated based on the first feature value and used as the floor loss rate.

[0009] The overall loss of the elevator is calculated based on the floor loss rate of each floor and the second characteristic value;

[0010] Upon receiving an external call, elevator group scheduling is performed based on the overall loss rate and the floor loss rate to ensure that the loss rate of each elevator is balanced.

[0011] In a second aspect, the present invention provides a scheduling device, comprising:

[0012] The data acquisition module is used to acquire historical operating data of multiple elevators in the elevator group;

[0013] The feature extraction module is used to extract, for each elevator, a first feature value representing the degree of wear and tear caused by the elevator during each floor stop and a second feature value representing the degree of wear and tear caused by the elevator during operation from the historical operation data.

[0014] The floor loss calculation module is used to calculate the loss of the elevator when it stops at each floor based on the first feature value, and use it as the floor loss.

[0015] The comprehensive loss calculation module is used to calculate the comprehensive loss of the elevator based on the floor loss of each floor and the second characteristic value;

[0016] The control module is used to schedule the elevator group based on the overall loss rate and the floor loss rate when receiving an external call, so as to balance the loss rate of each elevator.

[0017] Thirdly, the present invention provides an electronic device, the electronic device comprising:

[0018] At least one processor; and

[0019] A memory communicatively connected to the at least one processor; wherein,

[0020] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the scheduling method described in the first aspect of the invention.

[0021] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the scheduling method described in the first aspect of the present invention.

[0022] This invention provides a scheduling method. First, historical operating data of multiple elevators in an elevator group is acquired. For each elevator, a first characteristic value representing the degree of wear and tear during each floor stop and a second characteristic value representing the degree of wear and tear during operation are extracted from the historical operating data. The degree of wear and tear at each floor stop is calculated based on the first characteristic value, serving as the floor wear and tear. The overall degree of wear and tear of the elevator is calculated based on the floor wear and tear and the second characteristic value. Upon receiving an external call, elevator group scheduling is performed based on the overall degree of wear and tear and the floor wear and tear to ensure a balanced degree of wear and tear for each elevator. Therefore, when scheduling elevators in the elevator group to respond to an external call for a specific floor, the overall degree of wear and tear and the floor wear and tear can be combined for scheduling, making the overall degree of wear and tear of different elevators more consistent. This also makes the degree of wear and tear of different floors within the same elevator more consistent, and thus makes the lifespan of different elevators more consistent, avoiding large lifespan discrepancies between different elevators in a building.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] Example 1

[0031] Figure 1 This is a flowchart of a scheduling method provided in Embodiment 1 of the present invention. This embodiment is applicable to scheduling situations. The method can be executed by a scheduling device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the scheduling method includes:

[0032] S101. Obtain historical operating data of multiple elevators in the elevator group.

[0033] An elevator group consists of at least two elevators. It should be noted that a building may contain multiple elevator groups, and elevators within the same group serve the same floors.

[0034] Example: The target building has 50 floors and includes two elevator groups, A and B. Elevator group A includes elevators 1-4, which serve floors 1-30. Elevator group B includes elevators 5-8, which serve floors 31-50.

[0035] Historical elevator operation data can be data recorded during elevator operation. It is usually stored in the elevator's data management center, so historical elevator operation data can be obtained from the data management center.

[0036] S102. For each elevator, extract from historical operating data a first characteristic value representing the degree of wear and tear caused by the elevator during each floor stop, and a second characteristic value representing the degree of wear and tear caused by the elevator during operation.

[0037] Elevators typically utilize numerous devices during operation, stopping, door opening and closing, and receiving internal and external call commands (when users press buttons), including contact switches, load-bearing devices, and safety devices. Examples are shown below:

[0038] As an important suspension (load-bearing) component of elevators, steel wire ropes bear the weight of the entire car, but their service life is generally only about 5-8 years. Long-term high-frequency use will increase wear and tear and breakage.

[0039] Guide shoes have a service life of 4-5 years, but long-term high-frequency use will lead to severe wear and tear.

[0040] Speed ​​governors and safety brakes are important safety devices in elevators, and frequent use or operation can increase the risk of damage.

[0041] Door locks and buttons are particularly vulnerable parts of elevators, with a relatively short design lifespan, and their lifespan is basically determined by the frequency of use.

[0042] Furthermore, the contactors, relays, buffers, door systems, traction machines, and other components in the control cabinet all have corresponding service lives.

[0043] As can be seen from the above, the elevator's upward and downward movement, stopping, door opening and closing, and receiving internal and external call commands involve wear and tear on many devices. The degree of wear and tear on devices such as wire ropes, guide shoes, speed governors, safety brakes, and buttons is usually difficult to assess accurately. However, during elevator scheduling, data such as the number of trips, stops, opening and closing of (hall doors or car doors), number of internal and external call commands received, elevator load, and running time can be accurately obtained. Therefore, the degree of elevator wear and tear can be determined based on this accurately obtainable data, which can simply, efficiently, and accurately determine the degree of wear and tear on different elevators.

[0044] The loss rate during elevator stops refers to the wear and tear on only a portion of the elevator's components during and after a stop, while other components of the same type remain unused and undamaged in the current scenario. Therefore, the loss rate incurred during a stop at a specific floor can be considered. In this step, a first characteristic value representing the loss rate caused by the elevator stopping at each floor is extracted from historical operating data. This first characteristic value is used to calculate the floor loss rate during each floor stop. The larger the first characteristic value, the greater the elevator loss rate. For example, the first characteristic value may include the number of times the floor hall door opens and closes, the number of times the car door opens and closes, and the number of times the elevator makes in-floor calls. The floor hall door is the elevator lobby door in the elevator waiting area. Each elevator has one elevator hall door on each floor. These are parameters that change when the elevator stops at a floor and can be used as the first characteristic value representing the loss rate caused by the elevator stopping at each floor.

[0045] The degree of wear and tear incurred during elevator operation: Elevators typically require the operation of speed governors, safety brakes, and load-bearing ropes during ascent and descent, resulting in wear and tear on these devices. Therefore, this step extracts a second characteristic value representing the degree of wear and tear during elevator operation. This second characteristic value is used to schedule elevators based on the second characteristic value, aiming to balance the degree of wear and tear among different elevators. The larger the second characteristic value, the greater the degree of wear and tear. For example, the second characteristic value may include elevator load capacity, running time, etc.

[0046] In an optional example, the second characteristic value may also include the number of runs and the number of car door openings and closings, where the number of runs can be the number of elevator starts. The more runs and car door openings and closings, the greater the overall wear and tear on the elevator.

[0047] S103. Calculate the elevator's loss rate when it stops at each floor based on the first eigenvalue, and use it as the floor loss rate.

[0048] Floor loss rate refers to the existing losses incurred by the elevator when stopping at floors within a historical period (corresponding to historical operating data). Each floor of each elevator corresponds to a specific floor loss rate. After obtaining the first characteristic value, the sum of the first characteristic values ​​can be calculated to obtain the floor loss rate that needs to be considered when the elevator stops at the current floor. It should be noted here that "each floor of each elevator" refers to each floor designated for each elevator, not that the floor being stopped is part of the elevator.

[0049] S104. Calculate the overall loss of the elevator based on the floor loss rate and the second characteristic value of each floor.

[0050] The overall loss rate is calculated by taking into account the total loss of the elevator over a historical period (corresponding to historical operating data). Floor loss rate represents the loss incurred during elevator stops, while the second characteristic value corresponds to the loss incurred during elevator operation. Therefore, the overall loss rate can be calculated based on the floor loss rate and the second characteristic value for each floor. Specifically, the sum of the floor loss rate and the overall loss rate represented by the second characteristic value for each floor can be used as the overall loss rate. In other words, the overall loss rate is a parameter obtained by combining the loss incurred during stops and the loss incurred during operation.

[0051] S105. Upon receiving an external call, the elevator group is scheduled based on the overall loss rate and the floor loss rate to ensure that the loss rate of each elevator is balanced.

[0052] The overall loss rate is a parameter obtained by combining the loss rate during parking and the loss rate during operation. When receiving an external call, the elevator group is scheduled based on the overall loss rate and the floor loss rate. It can take into account both the overall loss rate and the floor loss rate, so that the overall loss rate of different elevators tends to be consistent, and the floor loss rate of different elevators and different floors also tends to be consistent.

[0053] This invention provides a scheduling method. First, historical operating data of multiple elevators in an elevator group is acquired. For each elevator, a first characteristic value representing the wear and tear caused by stopping at each floor and a second characteristic value representing the wear and tear caused during operation are extracted from the historical operating data. The wear and tear at each floor is calculated based on the first characteristic value, serving as the floor wear and tear. The overall wear and tear of the elevator is calculated based on the floor wear and tear and the second characteristic value. Upon receiving an external call, elevator group scheduling is performed based on the overall wear and tear and the floor wear and tear to ensure a balanced wear and tear for each elevator. Therefore, when scheduling elevators in the elevator group to respond to an external call for a specific floor, the overall wear and tear of different elevators can be combined for scheduling, making the overall wear and tear of different elevators more consistent. This also makes the wear and tear of different floors within the same elevator more consistent, and consequently, the lifespan of different elevators more consistent, avoiding significant lifespan discrepancies between elevators in a building.

[0054] Example 2

[0055] Figure 2 This is a flowchart of a scheduling method provided in Embodiment 2 of the present invention. This embodiment optimizes Embodiment 1 as described above. Figure 2 As shown, the scheduling method includes:

[0056] S201. Obtain historical operating data of multiple elevators in the elevator group.

[0057] S202. For each elevator, extract from historical operating data a first characteristic value representing the degree of wear and tear caused by the elevator during each floor stop, and a second characteristic value representing the degree of wear and tear caused by the elevator during operation.

[0058] S201 is similar to S101 in Embodiment 1, and you can refer to the relevant description in S101 for details.

[0059] The first characteristic value includes the number of calls within the floor and the number of times the floor hall door is opened and closed, while the second characteristic value includes the number of operations and the number of times the car door is opened and closed.

[0060] The analysis of the number of floor-level internal calls and the number of floor lobby door openings and closings in the first characteristic value is as follows:

[0061] When an elevator stops at a certain floor, it is necessary to control the opening of the hall door on that floor, while the hall doors on other floors do not need to be opened. As a result, the hall doors (including door switches, etc.) of the currently stopped floor will suffer wear and tear, while the hall doors on other floors will not suffer wear and tear.

[0062] When the elevator stops, after the user enters the car from the current floor, they need to press the internal call button to confirm other floors besides the current floor. Each internal call button corresponds to one floor. Therefore, at least one of the internal call buttons for other floors will experience wear and tear, while the internal call button for the current floor will not experience wear and tear in the current scenario.

[0063] Therefore, the greater the number of calls to the floor and the number of times the floor hall doors open and close, the greater the floor wear rate. The number of times the floor hall doors open and close for each current floor and the number of calls to the floor corresponding to each call button inside the car can be used as the first characteristic value.

[0064] Of course, the first characteristic value can also include only the number of times the floor hall door opens and closes. The specific value can be determined according to the actual needs. For example, when it is necessary to quickly determine the elevator that responds to the external call, the parameters can be reduced and only the number of times the floor hall door opens and closes is used as the first characteristic value. When it is necessary to determine the elevator that responds to the external call in a more detailed and accurate manner, the parameters can be increased and the number of times the floor hall door opens and closes and the number of times the floor is called internally can be used as the first characteristic value.

[0065] S203. For each floor of each elevator, obtain the number of floor calls and the number of times the hall door of the current floor is opened and closed from the first feature value.

[0066] For example, for elevator X, obtain the number of times it is called within its floors, N. x-1 N x-2 N x-3 ….N x-n ; represent the number of times the call button for each floor of elevator X, from floor 1 to n, respectively; that is, the number of times the call button for each floor inside the elevator car is pressed. Get the number of times the landing doors of each floor of elevator X have opened and closed, L x-1 L x-2 L x-3 ….L x-n ; represent the number of times the elevator doors for floor X and floors 1 to n have been opened and closed, respectively.

[0067] S204. Calculate the total number of in-floor calls for all floors except the current floor to obtain the in-floor call loss value.

[0068] When the elevator stops at a certain floor, after the user enters the car from that floor, they need to press an internal call button to confirm other floors besides the current floor. Each internal call button corresponds to one floor. Therefore, at least one internal call button for other floors incurs wear and tear, while the internal call button for the current floor does not incur wear and tear in the current scenario. Thus, we can consider only the wear and tear of the internal call buttons for other floors, ignoring the wear and tear of the button for the current floor. For example, if the current floor is the 2nd floor, we can calculate the total number of internal call calls for all floors except the 2nd floor.

[0069] The internal recall loss value on the second floor is S2 = N. x-1 +N x-3 +….+N x-n .

[0070] Where, N x This indicates the number of times a call is made within a different floor.

[0071] S205. Calculate the sum of the internal call loss value and the number of times the floor hall door of the current floor is opened and closed to obtain the floor loss degree of the current floor.

[0072] For example, if the current floor is the 2nd floor, the number of times the floor hall door of the 2nd floor is opened and closed is L2, and the internal call loss value of the 2nd floor is S2, then the floor loss degree of the 2nd floor is M2 = S2 + L2.

[0073] S206. For each elevator, calculate the total floor loss at each floor to obtain the total floor loss value.

[0074] The floor loss rates from floor 1 to floor n are M1, M2, ..., Mn, respectively.

[0075] Total floor loss S of elevator X x楼 =M1+M2….+Mn.

[0076] S207. Calculate the elevator's overall loss rate based on the number of runs, the number of car door openings and closings, and the total floor loss value in the second characteristic value.

[0077] For example, the sum of the number of runs, the number of car door openings and closings, and the total floor loss in the second characteristic value can be calculated as the comprehensive loss degree of the elevator. The number of runs, the number of car door openings and closings, and the total floor loss can be combined into the comprehensive loss degree.

[0078] Optionally, the overall loss degree of the elevator can be calculated based on the number of runs, the number of car door openings and closings, and the total floor loss value in the second characteristic value, including: assigning weights to the number of runs, the number of car door openings and closings, and the total floor loss value in the second characteristic value respectively; calculating the weighted sum of the number of runs, the number of car door openings and closings, and the total floor loss value to obtain the overall loss degree of the elevator.

[0079] The overall loss rate Z of elevator X x =aN x运 +bN x轿 +cS x楼 .

[0080] Where a, b, and c are the weights assigned to the number of operations, the number of car door openings and closings, and the total floor loss, respectively, N x运 Let N be the number of times elevator X is run. x轿 S represents the number of times the car door of elevator X opens and closes. x楼 This represents the total floor loss.

[0081] By setting weights, the importance of the number of runs, the number of car door openings and closings, and the total floor loss in determining the overall loss of the elevator can be allocated. The specific weights of these three factors can be set according to the needs of the elevator maintenance company.

[0082] S208. Upon receiving an external call, the elevator group is scheduled based on the overall loss rate and the floor loss rate to ensure that the loss rate of each elevator is balanced.

[0083] Specifically, this includes: upon receiving an external call, determining the corresponding floor; for each elevator, obtaining the floor loss degree corresponding to the floor where the external call occurred, as the target floor loss degree; assigning weights to the elevator's overall loss degree and the target floor loss degree respectively; calculating the weighted sum of the elevator's overall loss degree and the target floor loss degree to obtain the allocation value; and scheduling multiple elevators based on the allocation value, with the scheduling priority of the elevator being inversely proportional to the allocation value.

[0084] For example, the elevator group of the target building includes elevators 1-4. When an outbound call is received, the corresponding floor is determined, for example, the 2nd floor, and the floor loss rate N of elevators 1-4 is obtained respectively. 1-2 N 2-2 N 3-2 N 4-2 Let Z1, Z2, Z3, and Z4 be the target floor loss rates for elevators 1-4, respectively; and let Z4 be the comprehensive loss rates for elevators 1-4, with weights allocated as follows: comprehensive elevator loss rate 0.4 and target floor loss rate 0.6.

[0085] The allocation value for ladder number 1 is P1 = 0.4 * Z1 + 0.6 * N. 1-2 ;

[0086] The allocation value for ladder number 2 is P2 = 0.4 * Z2 + 0.6 * N. 2-2 ;

[0087] The allocation value for ladder number 3 is P3 = 0.4 * Z3 + 0.6 * N. 3-2 ;

[0088] The allocation value for ladder number 4 is P4 = 0.4 * Z4 + 0.6 * N. 4-2 ;

[0089] Ultimately, multiple elevators can be scheduled based on their allocation values. The scheduling priority of an elevator is inversely proportional to its allocation value. For example, if the allocation value P2 of elevator number 2 is the smallest, then elevator number 2 can be selected as the elevator to respond to the current external call.

[0090] Optionally, before scheduling multiple elevators based on allocation values, the following steps are also included:

[0091] Determine if the current time falls within the preset peak period; if not, execute the step of scheduling multiple elevators based on the allocation value; if so, obtain the floor difference between the current floor and the floor called by each elevator; filter out candidate elevator numbers from multiple elevators based on the floor difference; schedule the elevators corresponding to the candidate elevator numbers based on the allocation value, with the scheduling priority of the elevators being inversely proportional to the allocation value.

[0092] Peak hours are times when elevators are used more frequently and there is a large flow of users. Priority should be given to ensuring the carrying efficiency of elevators. Therefore, if the current time is not within the preset peak hours, the floor difference between the current floor of each elevator and the floor called by the external call can be obtained, and the alternative elevator number can be filtered based on the floor difference. This is to ensure response speed and carrying efficiency.

[0093] Based on the floor difference, the candidate elevator number can be selected. Specifically, the elevator number with the smallest floor difference can be selected as the candidate elevator number, which is also the only elevator number. In subsequent steps, the elevator with this elevator number can be directly dispatched, which can quickly respond to external calls and improve transportation efficiency.

[0094] Another approach to selecting candidate elevator numbers based on floor differences is to: use the elevator number with the smallest floor difference as the reference elevator number; then, obtain other elevator numbers whose floor differences with the reference elevator number are within a preset range, and add them as new elevator numbers. Combine the reference elevator number and the new elevator numbers as candidate elevator numbers. This increases the number of candidate elevator numbers, especially when multiple elevators stop at relatively close floors.

[0095] For example, if the floor called is the 2nd floor, and the current floors where elevators 1-4 are currently stopped are the 12th, 15th, 22nd, and 17th floors respectively, then the floor differences between the current floors of elevators 1-4 and the floor called are 10, 13, 20, and 15 (unit: floors), with a preset difference range of 4. Therefore, elevator number 1 is the reference elevator, and elevator number 2 is the newly added elevator. Elevators 1 and 2 are then considered as backup elevator numbers. Generally, elevators with close floor proximity take roughly the same amount of time to reach the same floor. For example, calling elevator 1 takes 8 seconds, while calling elevator 2 takes 9.5 seconds. Since their call times are similar, both can be considered as backup elevator numbers. In subsequent steps, these can be combined with allocation values ​​to schedule elevators, ensuring response speed and carrying efficiency while balancing wear and tear between different elevators.

[0096] Of course, other operating strategies can also be adopted. For example, during peak hours, prioritizing carrying efficiency, the nearest elevator can be used to quickly respond to external calls; while during off-peak hours, considering a balanced lifespan response method, the elevator with the lowest wear and tear can be used to respond to external calls.

[0097] In this embodiment, for each floor of each elevator, the number of in-floor calls and the number of hall door openings / closings for the current floor are obtained from the first feature value. The sum of the in-floor calls for all floors except the current floor is calculated to obtain the in-floor call loss value. The sum of the in-floor call loss value and the number of hall door openings / closings for the current floor is calculated to obtain the floor loss degree of the current out-of-floor call. For each elevator, the sum of the floor loss degrees for each floor is calculated to obtain the total floor loss value. The overall loss degree of the elevator is calculated based on the number of trips, the number of car door openings / closings, and the total floor loss value from the second feature value. By setting weights, the importance of the number of trips, the number of car door openings / closings, and the total floor loss value in determining the overall loss degree of the elevator can be allocated, thereby enabling elevator scheduling based on a balanced elevator loss degree.
