[0034] In the electrical control circuit of the elevator, multiple parts and components require contacts to realize the switching, signal transmission and control functions of the circuit, such as push button switches, relays, door lock circuit switches, etc. These switches are prone to wear and tear after multiple collisions and frictions during long-term operation of the elevator, which can lead to problems such as poor contact of contacts, unstable signal transmission or circuit failure. Therefore, it is necessary to test the durability of the elevator switch to ensure elevator safety.

[0035] Based on this, in order to improve the technical problem in the related art that the elevator switch contacts are worn due to collision and friction, which endangers the safety of the elevator, the embodiment of the present application provides the following solution.

[0036] See also Figure 1 The embodiment of the present application provides an elevator switch durability test device 100, which includes a support portion 10, a control portion 20, a fixing portion 30 and a trigger portion 40, wherein:

[0037] The control unit 20 is disposed on the support unit 10 .

[0038] The fixing part 30 is disposed on the supporting part 10 , and is used to fix the elevator switch and obtain the triggering times of the elevator switch and the resistance value at each triggering.

[0039] Triggering section 40 The triggering section 40 includes a first triggering device 41 and a second triggering device 42. The first triggering device 41 is rotatably disposed on the supporting portion 10 and is located on one side of the fixing portion 30. The first triggering device 41 is used to rotate to trigger the elevator switch, and rotate in another direction to separate from the elevator switch; the second triggering device 42 is movably disposed on the supporting portion 10, for driving the first triggering device 41 to rotate, and for acquiring an image of the elevator switch.

[0040] The control unit 20 is connected to the trigger unit 40 and the fixing unit 30 for communication.

[0041] It can be understood that the support part 10 is a supporting structure that can play a supporting role. For example, the support part 10 can be an aluminum support frame, an iron support frame, etc., but it is not limited to this. The control part 20 is a control device. For example, the control part 20 can be a manual control panel, a PLC control panel, etc., but it is not limited to this. The fixing part 30 is a fixing device that can fix the elevator switch and obtain the number of triggering times of the elevator switch and the resistance value at each triggering. For example, the fixing part 30 can include a mounting plate (aluminum plate, plastic plate, etc.), a clamping device (spring clamping claw, mechanical hand claw, etc.) arranged on the mounting plate, and a measuring device (loop resistance tester, switch resistance tester, etc.) arranged on the mounting plate, etc., but it is not limited to this. The first trigger device 41 is a trigger mechanism 414 that can rotate. For example, the first trigger device 41 can include a rotating member (a flat turntable, exhibition turntable, etc.) and a trigger member (conductive trigger rod, flexible trigger rod, etc.) arranged on the rotating member, etc., but it is not limited to this. The second trigger device 42 is a driving device that can drive the first trigger device 41 to move back and forth and obtain an image of the elevator switch. For example, the second trigger device 42 may include a driving mechanism (linear actuator, pneumatic drive device) and a camera device (web camera, analog camera), etc., but is not limited to this.

[0042] As can be seen from the above, the elevator switch durability test device 100 provided in the embodiment of the present application provides support through the support part 10, which is convenient for the user to operate. The elevator switch to be tested is fixed by the fixing part 30, and the elevator switch is counted when it is triggered, and the resistance value of the elevator switch is recorded each time the elevator switch is triggered. The first trigger device 41 is rotated to trigger the elevator switch, and the first trigger device 41 is driven to rotate in another direction by the second trigger device 42 to separate the first trigger device 41 from the elevator switch, and the image of the elevator switch is obtained when the first trigger device 41 is separated from the elevator switch. The moving speed of the second moving device is controlled by the control part 20, so as to control the triggering frequency of the elevator switch, and obtain the number of triggering times of the elevator switch obtained by the fixing part, the resistance value at each triggering, and the image of the elevator switch obtained by the second trigger device after each triggering.

[0043] In some embodiments, please refer to Figure 1 and Figure 2 The trigger unit 40 also includes a motion device 43 , which is disposed on the support unit 10 and is in communication connection with the control unit 20 .

[0044] Among them, the motion device 43 is used to drive the second trigger device 42 to move close to the first trigger device 41 and drive the first trigger device 41 to rotate, so that the first trigger device 41 is separated from the elevator switch, or drive the second trigger device 42 away from the first trigger device 41 to make the first trigger device 41 rotate in another direction to trigger the elevator switch.

[0045] It can be understood that the motion device 43 is a driving device that can drive the second trigger device 42 to move back and forth. For example, the motion device 43 can be a linear actuator, a pneumatic driving device, etc., but is not limited thereto.

[0046] With such arrangement, when it is necessary not to trigger the elevator switch, the motion device 43 drives the second trigger device 42 to move close to the first trigger device 41 and drives the first trigger device 41 to rotate, so that the first trigger device 41 is separated from the elevator switch; when it is necessary to trigger the elevator switch, the motion device 43 drives the second trigger device 42 away from the first trigger device 41 so that the first trigger device 41 rotates in another direction and contacts the elevator switch, so as to trigger the elevator switch; the motion device 43 can drive the first trigger device 41 to repeatedly approach the first trigger device 41 and move away from the first trigger device 41, so that the elevator switch cycles between the two states of being triggered and not being triggered, thereby realizing the automatic testing of the elevator switch.

[0047] In some embodiments, see Figure 2 The moving device 43 includes a driving member 431 , a first connecting member 432 , a fixing member 433 and a second connecting member 434 .

[0048] The driving member 431 is disposed on the supporting portion 10 and is in communication connection with the control portion 20 .

[0049] The first connecting member 432 is disposed on the power output shaft of the driving member 431 , and a moving groove is formed on the first connecting member 432 .

[0050] The fixing member 433 is movably disposed on the first connecting member 432 along the movable groove.

[0051] One end of the second connecting member 434 is rotatably connected to the fixing member 433 , and the other end of the second connecting member 434 is rotatably connected to the second trigger device 42 .

[0052] The driving member 431 is used to drive the first connecting member 432 to rotate so as to drive the fixing member 433 to rotate, thereby driving the second connecting member 434 to move, thereby driving the second trigger device 42 to move.

[0053] It can be understood that the driving member 431 is a driving device capable of driving the first connecting member 432 to rotate. For example, the driving member 431 can be a servo motor, a DC motor, etc., but is not limited thereto. The first connecting member 432 is a rod-shaped structure. For example, the first connecting member 432 can be an aluminum rod, a plastic rod, etc., but is not limited thereto.

[0054] The fixing member 433 is a fixing device that can move along the movable groove and is fixed to the first connecting member 432. For example, the fixing member 433 may include a slider (an outer slider, an inner slider, etc.) movably arranged on the movable groove and a locking mechanism (a rotary locker, a bolt fastener) arranged on the slider, etc., but is not limited to this, wherein the locking mechanism is used to approach the slider and make the first connecting member 432 simultaneously contacted by the slider and the locking mechanism.

[0055] The second connecting member 434 is a rod-shaped structure. For example, the second connecting member 434 may be an aluminum rod, a plastic rod, etc., but is not limited thereto.

[0056] In this way, when the fixing member 433 is moved and fixed to the position closest to the fixing member 433, the moving distance of the second trigger device 42 is the shortest; when the fixing member 433 is moved and fixed to the position farthest from the fixing member 433, the moving distance of the second trigger device 42 is the longest; when the driving member 431 drives the first connecting member 432 to rotate and makes the end of the first connecting member 432 away from the driving member 431 away from the second trigger device 42, the first connecting member 432 drives the fixing member 433 to move away from the second trigger device 42 at the same time, and the fixing member 433 moves away from the second trigger device 42. 33 and simultaneously drives the second connecting member 434 away from the second trigger device 42, thereby driving the second trigger device 42 to approach the driving member 431; when the driving member 431 drives the first connecting member 432 to rotate and makes the end of the first connecting member 432 away from the driving member 431 approach the second trigger device 42, the first connecting member 432 drives the fixing member 433 to approach the second trigger device 42 at the same time, and the fixing member 433 simultaneously drives the second connecting member 434 to approach the second trigger device 42, thereby driving the second trigger device 42 away from the driving member 431.

[0057] In some embodiments, see Figure 1 and Figure 2 The support portion 10 includes a movable shaft 11, which is arranged on the support portion 10 and is located below the fixed portion 30 and parallel to the rotation direction of the second trigger device 42. The second trigger device 42 includes a movable plate 421, a push plate 422 and an image acquisition device 423.

[0058] The moving plate 421 is movably disposed on the moving shaft 11 .

[0059] The push plate 422 is disposed on one side of the moving plate 421 close to the first trigger device 41 . The push plate 422 is used to abut against the first trigger device 41 to push the first trigger device 41 away from the fixing portion 30 .

[0060] The image acquisition device 423 is arranged on the movable plate 421 and is located below the fixed part 30, and is communicated with the control part 20. The image acquisition device 423 is used to acquire the image of the elevator switch when the movable plate 421 moves to the farthest distance from the fixed part 30 and is located directly below the fixed part 30.

[0061] The other end of the second connecting member 434 is rotatably connected to the moving plate 421 , and the driving member 431 is used to drive the moving plate 421 to move closer to or away from the first trigger device 41 along the moving axis 11 .

[0062] It can be understood that the movable plate 421 is a plate-like structure that can move along the movable shaft 11. For example, the movable plate 421 can be a bent plate, an aluminum plate, etc., but not limited thereto. The push plate 422 is a structure that can drive the first trigger device 41 to rotate. For example, the push plate 422 can be an aluminum rod, an aluminum plate, etc., but not limited thereto. The image acquisition device 423 is a device that can acquire an image of the elevator switch. For example, the image acquisition device 423 can be a network camera, an analog camera, etc., but not limited thereto.

[0063] With such arrangement, when the elevator switch needs to be untriggered, the moving plate 421 moves along the moving axis 11 close to the first trigger device 41 and away from the driving member 431, so that the push plate 422 contacts the first trigger device 41 and drives the push plate 422 to rotate counterclockwise, so that the portion of the first trigger device 41 in contact with the elevator switch is separated from the elevator switch. When the moving plate 421 moves along the moving axis 11 close to the first trigger device 41 and away from the driving member 431, the image acquisition device 423 is driven by the moving plate 421 to approach the elevator switch. When the moving plate 421 moves to the farthest distance from the driving member 431, the image acquisition device 423 is driven by the moving plate 421 to the bottom of the elevator switch and captures an image of the elevator switch.

[0064] When the elevator switch needs to be triggered, the moving plate 421 moves away from the first trigger device 41 and approaches the driving member 431 along the moving axis 11. The first trigger device 41 rotates clockwise under the action of gravity, so that the part of the first trigger device 41 separated from the elevator switch contacts the elevator switch to trigger the elevator switch. When the moving plate 421 moves away from the first trigger device 41 and approaches the driving member 431 along the moving axis 11, the image acquisition device 423 is driven by the moving plate 421 away from the elevator switch.

[0065] In some embodiments, see Figure 1 and Figure 2 The first trigger device 41 includes a rotating plate 411 , a rotating wheel 412 , a counterweight block 413 and a trigger mechanism 414 .

[0066] The rotating plate 411 is rotatably disposed on the supporting portion 10 .

[0067] The rotating wheel 412 is rotatably disposed on the rotating plate 411 and corresponds to the position of the pushing plate 422 .

[0068] The counterweight 413 is detachably disposed at one end of the rotating plate 411 away from the fixing portion 30 .

[0069] The trigger mechanism 414 is disposed at one end of the rotating plate 411 close to the fixing portion 30 and is located below the fixing portion 30 . The trigger mechanism 414 is used to trigger the elevator switch.

[0070] The push plate 422 is used to abut against the rotating wheel 412 to drive the rotating plate 411 to rotate, so that the trigger mechanism 414 is away from the fixed part 30, and the counterweight block 413 is used to drive the rotating plate 411 to rotate in the opposite direction, so that the trigger mechanism 414 is close to and abuts against the fixed part 30 to trigger the elevator switch.

[0071] It can be understood that the rotating plate 411 is a plate-like structure, for example, the rotating plate 411 can be an aluminum plate, a plastic plate, etc., but not limited thereto. The rotating wheel 412 is a wheel, for example, the rotating wheel 412 can be a rubber wheel, an inflatable wheel, etc., but not limited thereto. The counterweight block 413 is a block-mounted structure, for example, the counterweight block 413 can be a magnetic block, a lead block, etc., but not limited thereto. The trigger mechanism 414 is a mechanism that can trigger the elevator switch, for example, the trigger mechanism 414 can be a mechanical trigger, an electromagnetic relay, etc., but not limited thereto.

[0072] In this arrangement, when the push plate 422 approaches and contacts the rotating wheel 412 and causes the rotating wheel 412 to rotate, the rotating wheel 412 drives the rotating plate 411 to rotate counterclockwise, thereby driving the trigger mechanism 414 in contact with the elevator switch to be separated from the elevator switch; when the push plate 422 moves away from the rotating wheel 412, the rotating plate 411 rotates clockwise under the action of the gravity of the counterweight block 413, thereby driving the trigger mechanism 414 separated from the elevator switch to contact the elevator switch to trigger the elevator switch.

[0073] In some embodiments, see Figure 3 The fixing part 30 includes a fixing plate 31 , a fixing mechanism 32 and a detection mechanism 33 .

[0074] The fixing plate 31 is disposed on the supporting portion 10 .

[0075] The fixing mechanism 32 is disposed on the fixing plate 31 and is used to fix the elevator switch.

[0076] The detection mechanism 33 is arranged on the fixing plate 31 and is located beside the fixing mechanism 32, and is electrically connected to the elevator switch and is in communication connection with the control unit 20. The detection mechanism 33 is used to obtain the number of triggering times of the elevator switch and the resistance value at each triggering when the elevator switch is triggered.

[0077] It can be understood that the fixing plate 31 is a plate-like structure, for example, the fixing plate 31 can be a copper plate, an aluminum plate, etc., but not limited thereto. The fixing mechanism 32 is a fixing device capable of fixing the elevator switch, for example, the fixing mechanism 32 can be an electric clamp, a magnetic clamp, etc., but not limited thereto. The detection mechanism 33 is a detection device capable of recording the number of times the elevator switch is triggered and the resistance value at each triggering when the elevator switch is triggered, for example, the detection mechanism 33 can be an elevator safety switch circuit resistance detection device, an elevator resistance tester, etc., but not limited thereto.

[0078] In this way, the elevator switch to be tested is fixed to the fixing plate 31 by the fixing mechanism 32, and the elevator switch is located at a position where it can be triggered by the trigger mechanism 414, which is convenient for subsequent testing. The detection mechanism 33 records the number of times the elevator switch is triggered and the resistance value at each triggering when the elevator switch is triggered, providing data support for analyzing the durability of the elevator switch.

[0079] See also Figure 4 The embodiment of the present application further provides an elevator switch durability test method, which is applied to any of the elevator switch durability test devices 100 described above. The elevator switch durability test method includes:

[0080] Acquire trigger information; wherein the trigger information includes multiple trigger serial numbers, trigger resistance information and trigger image information, the trigger resistance information includes multiple trigger resistance values ​​arranged in sequence according to the acquisition order, the trigger image information includes multiple trigger images arranged in sequence according to the acquisition order, each trigger serial number corresponds to a trigger resistance value and a trigger image, the trigger resistance value reflects the resistance value when the elevator switch is triggered, and the trigger image reflects the contact image after the elevator switch is triggered.

[0081] The durability analysis information is obtained based on the trigger information; wherein the durability analysis information includes a durability critical number and a critical maintenance interval, the durability critical number reflects the triggering number of the elevator switch, and the critical maintenance interval reflects the interval range of the triggering number of the elevator switch.

[0082] A durability analysis report is obtained based on the durability analysis information; wherein the durability analysis report reflects the durability of the elevator switch.

[0083] From the above, it can be seen that the elevator switch durability test method provided in the embodiment of the present application, by obtaining trigger information including multiple trigger numbers, trigger resistance information and trigger image information, collects data reflecting the physical properties of the elevator switch, and provides a basis for subsequent steps. Then, by obtaining durability analysis information including the critical durability number and the critical maintenance interval based on the trigger information, the maximum number of triggers of the elevator switch without affecting the working performance is obtained, and the elevator switch needs to be repaired or replaced within a certain range of trigger times. Finally, a durability analysis report reflecting the durability of the elevator switch is obtained based on the durability analysis information, which can provide reference and suggestions for users to analyze the durability of the elevator switch, save users' analysis time, and improve analysis efficiency.

[0084] In order to better understand the elevator switch durability test method provided in the embodiment of the present application, the specific implementation process of the elevator switch durability test method provided in the embodiment of the present application is exemplarily introduced below.

[0085] Figure 4 A schematic flow chart of an elevator switch durability test method provided in an embodiment of the present application is shown. The elevator switch durability test method includes:

[0086] S100, acquiring trigger information; wherein the trigger information includes multiple trigger serial numbers, trigger resistance information and trigger image information, the trigger resistance information includes multiple trigger resistance values ​​arranged in sequence according to the acquisition order, the trigger image information includes multiple trigger images arranged in sequence according to the acquisition order, each trigger serial number corresponds to a trigger resistance value and a trigger image, the trigger resistance value reflects the resistance value when the elevator switch is triggered, and the trigger image reflects the contact image after the elevator switch is triggered.

[0087] It is understood that the way to obtain the trigger information may be to receive data transmitted by the user, or to receive data transmitted by the image acquisition device 423 and the detection mechanism 33, but is not limited thereto. Acquiring the trigger information including multiple trigger numbers, trigger resistance information and trigger image information can provide a basis for subsequent steps.

[0088] For example, assuming that trigger resistance values ​​A1, A2, and A3 are acquired in sequence, and trigger images B1, B2, and B3 are acquired in sequence, the corresponding relationship between the trigger sequence number and the trigger resistance value and the trigger image is:

[0090] S200, obtaining durability analysis information based on the trigger information; wherein the durability analysis information includes a durability critical number and a critical maintenance interval, the durability critical number reflects the triggering number of the elevator switch, and the critical maintenance interval reflects the interval range of the triggering number of the elevator switch.

[0091] It is understood that the durability analysis information can be obtained based on the trigger information by sending the trigger information to the user and then receiving the data sent back by the user, or by analyzing the trigger resistance value in the trigger information and the wear area on the trigger image, etc., but is not limited thereto. The durability analysis information obtained based on the trigger information can obtain the maximum number of triggers of the elevator switch without affecting the working performance, and the suggestion of repairing or replacing the elevator switch within the range of the number of triggers.

[0092] In one possible implementation, see Figure 5 , S200, obtaining durability analysis information based on the trigger information, including:

[0093] S210, obtaining resistance analysis information based on the trigger resistance information; wherein the resistance analysis information includes first resistance critical information and second resistance critical information.

[0094] It can be understood that the way to obtain the resistance analysis information based on the trigger resistance information can be to send the trigger resistance information to the user and then receive the data sent back by the user, or to analyze the size of each trigger resistance value in the trigger resistance information, but is not limited thereto. Obtaining the resistance analysis information including the first resistance critical information and the second resistance critical information based on the trigger resistance information can provide a basis for analyzing the durability performance of the elevator switch.

[0095] In one possible implementation, see Figure 5 , S210, obtaining resistance analysis information based on the trigger resistance information, including:

[0096] S211, starting from the trigger number 1, determine whether the trigger resistance value corresponding to the trigger number is greater than the preset resistance value; if the trigger resistance value is greater than or equal to the preset resistance value, confirm the trigger number corresponding to the trigger resistance value as the first resistance critical information.

[0097] It can be understood that starting from the trigger sequence number 1, judging whether the trigger resistance value corresponding to the trigger sequence number is greater than the preset resistance value is to judge all the acquired trigger resistance values ​​separately. If the trigger resistance value is greater than or equal to the preset resistance value, it means that the durability of the elevator switch after the trigger is lower than the user's expected performance. Then confirming the trigger sequence number corresponding to the trigger resistance value as the first resistance critical information can clarify the maximum number of triggers of the elevator switch without affecting the durability, providing a basis for subsequent steps.

[0098] S212, step a, confirm the trigger resistance value corresponding to the trigger number with serial number n as the first resistance value, confirm the trigger resistance value corresponding to the trigger number with serial number n+m as the second resistance value, and determine whether the resistance difference is greater than the preset resistance difference; wherein, n=1, m=50, and the resistance difference is the absolute value of the difference between the first resistance value and the second resistance value.

[0099] It is understood that m can use the default value of 50, or can be a natural value defined by the user before starting the test. The preset resistance difference can be 0.5, or can be defined by the user, but is not limited thereto. . Determining whether the resistance difference is greater than the preset resistance difference is to determine whether the resistance value of the elevator switch within the m triggering times has a relatively obvious (beyond the user's expectation) increase.

[0100] For example, assuming that the value of the first resistor is 5 ohms and the value of the second resistor is 6 ohms, the resistance difference=|5-6|=1 ohm.

[0101] S213: If the resistance difference is greater than or equal to the preset resistance difference, confirming the trigger number with the number n as the second resistance critical information.

[0102] It can be understood that if the resistance difference is greater than or equal to the preset resistance difference, it means that the resistance change rate of the elevator switch within m triggers exceeds the user's expectation. Then confirming the trigger number with the sequence number n as the second resistance critical information can provide a basis for subsequent steps.

[0103] S214, if the resistance difference is less than the preset resistance difference, n+1 is substituted into n in step a and step a is repeated.

[0104] It can be understood that if the resistance difference is less than the preset resistance difference, it means that the resistance change rate of the elevator switch within m triggers meets the user's expectations. Substituting n+1 into n in step a and repeating step a can ensure that all the resistance values ​​obtained are analyzed to ensure the reliability of the test.

[0105] Exemplarily, assuming that when step a is performed for the first time, the value of n in step a is 1, then when step a is performed for the second time, the value of n in step a is 2, when step a is performed for the third time, the value of n in step a is 3, and so on.

[0106] S215: If the value of n+m is greater than any trigger sequence number, then end step a.

[0107] It can be understood that if the value of n+m is greater than any trigger sequence number, it means that all the acquired resistance values ​​have been analyzed and there is no need to perform step a again.

[0108] S216: Confirm the first critical resistance information and the second critical resistance information as resistance analysis information.

[0109] It can be understood that confirming the first critical resistance information and the second critical resistance information as resistance analysis information can provide a basis for subsequent steps.

[0110] S220, obtaining wear analysis information based on the trigger image information; wherein the wear analysis information includes first wear information and second wear information.

[0111] It can be understood that the wear analysis information can be obtained based on the trigger image information by sending the trigger image information to the user and then receiving the data sent back by the user, or by analyzing the wear area of ​​the elevator switch contact on each trigger image in the trigger image information, but is not limited thereto. The wear analysis information including the first wear information and the second wear information obtained based on the trigger image information can provide a basis for subsequent steps.

[0112] In one possible implementation, see Figure 5 , S220, obtaining wear analysis information based on the trigger image information, including:

[0113] S221, starting from the trigger number 1, the trigger images corresponding to the trigger numbers are input into the image analysis model in sequence to obtain the wear ratio corresponding to the trigger image; wherein the image analysis model is a data model obtained through machine learning, the wear ratio is the ratio of the contact wear area of ​​the elevator switch to the total contact area, the contact wear area reflects the area of ​​the contact wear of the elevator switch, and the total contact area is the surface area of ​​the contact of the elevator switch.

[0114] It can be understood that the image analysis model is obtained through machine learning training using multiple sets of data, and the multiple sets of data include first-category data and second-category data. Each set of data in the first category includes: at least one image of a worn elevator switch contact, the identified wear area in the image and the wear area value corresponding to the wear area, and the total area value of the elevator switch electric shock; each set of data in the second category includes: an image of an elevator switch contact that is not worn and a label indicating that the image is not worn. Starting from the trigger number 1, the trigger images corresponding to the trigger numbers are input into the image analysis model in sequence, that is, all the acquired trigger images are analyzed. Obtaining the wear ratio corresponding to the trigger image can provide a basis for subsequent steps.

[0115] For example, assuming that the contact wear area is 200 pixels and the total contact area is 10,000 pixels, the wear ratio = 200 / 10,000 = 0.02.

[0116] S222, determining whether the wear ratio is greater than or equal to a preset wear ratio; if the wear ratio is greater than or equal to the preset wear ratio, confirming the trigger sequence number corresponding to the trigger image corresponding to the wear ratio as the first wear information.

[0117] It can be understood that judging whether the wear ratio is greater than or equal to the preset wear ratio is to judge whether the wear area of ​​the elevator switch contact is too large. If the wear ratio is greater than or equal to the preset wear ratio, it means that the wear degree of the elevator switch contact exceeds the user's expectations, which may have an adverse effect on the operation of the elevator. Confirming the trigger sequence number corresponding to the trigger image corresponding to the wear ratio as the first wear information can provide a basis for subsequent steps.

[0118] S223, step b, confirm the wear ratio corresponding to the trigger image corresponding to the trigger number x as the first wear ratio, confirm the wear ratio corresponding to the trigger image corresponding to the trigger number x+y as the second wear ratio, and judge whether the wear difference is greater than the preset wear difference; wherein, x=1, y=100, and the wear difference is the absolute value of the difference between the first wear ratio and the second wear ratio.

[0119] It is understood that y can use the default value of 100, or can be a natural value customized by the user before starting the test. The preset wear difference value can be 0.002, or can be customized by the user, etc., but is not limited thereto. Determining whether the wear difference value is greater than the preset wear difference value is to determine whether the rate of change of the wear degree of the contact of the elevator switch exceeds the user's expectation within y triggers.

[0120] For example, assuming that the first wear ratio is 0.02 and the second wear ratio is 0.021, the wear difference = |0.02-0.021| = 0.001.

[0121] S224: If the wear difference is greater than or equal to the preset wear difference, confirm the trigger sequence number x as the second wear information.

[0122] It can be understood that if the wear difference is greater than or equal to the preset wear difference, it means that the wear degree change rate of the contact of the elevator switch exceeds the user's expectations within y triggering times, which may have an adverse effect on the operation of the elevator.

[0123] S225, if the wear difference is less than the preset wear difference, substitute x+1 into x in step b and repeat step b.

[0124] It can be understood that if the wear difference is less than the preset wear difference, it means that the wear rate of the contact of the elevator switch meets the user's expectations within y triggers. Substituting x+1 into x in step b and repeating step b can ensure that all the acquired trigger images are analyzed, thereby ensuring the reliability of the test.

[0125] Exemplarily, assuming that when step b is performed for the first time, the value of x in step b is 1, then when step b is performed for the second time, the value of x in step b is 2, when step b is performed for the third time, the value of x in step b is 3, and so on.

[0126] S226: If the value of x+y is greater than any trigger sequence number, then end step b.

[0127] It can be understood that if the value of x+y is greater than any trigger sequence number, it means that all the acquired trigger images are analyzed.

[0128] S227, confirming the first wear information and the second wear information as wear analysis information.

[0129] It can be understood that confirming the first wear information and the second wear information as wear analysis information can provide a basis for subsequent steps.

[0130] S230, obtaining durability analysis information based on the resistance analysis information and the wear analysis information.

[0131] It can be understood that the durability analysis information can be obtained based on the resistance analysis information and the wear analysis information by sending the resistance analysis information and the wear analysis information to the user and then receiving the data sent back by the user, or by analyzing the first resistance critical information, the second resistance critical information, the first wear information, and the second wear information, etc., but is not limited thereto. The durability analysis information obtained based on the resistance analysis information and the wear analysis information can provide a basis for subsequent steps.

[0132] In one possible implementation, see Figure 6 S230, obtaining durability analysis information based on the resistance analysis information and the wear analysis information, including:

[0133] S231, determine whether the trigger number corresponding to the first resistance critical information is greater than or equal to the trigger number corresponding to the first wear information; if the trigger number corresponding to the first resistance critical information is greater than or equal to the trigger number corresponding to the first wear information, then the trigger number corresponding to the first wear information is confirmed as the endurance critical number; if the trigger number corresponding to the first resistance critical information is less than the trigger number corresponding to the first wear information, then the trigger number corresponding to the first resistance critical information is confirmed as the endurance critical number.

[0134] It can be understood that judging whether the trigger sequence number corresponding to the first resistance critical information is greater than or equal to the trigger sequence number corresponding to the first wear information is to judge the minimum number of times the elevator switch may affect the operation of the elevator after being triggered. If the trigger sequence number corresponding to the first resistance critical information is greater than or equal to the trigger sequence number corresponding to the first wear information, it means that the elevator switch may affect the operation of the elevator after being triggered by the trigger sequence number corresponding to the first wear information. If the trigger sequence number corresponding to the first resistance critical information is less than the trigger sequence number corresponding to the first wear information, it means that the elevator switch may affect the operation of the elevator after the trigger sequence number corresponding to the first resistance critical information. Confirming the trigger sequence number corresponding to a wear information as the endurance critical number or confirming the trigger sequence number corresponding to the first resistance critical information as the endurance critical number can provide a basis for subsequent steps.

[0135] S232, among the trigger number corresponding to the first resistance critical information, the trigger number corresponding to the second resistance critical information, the trigger number corresponding to the first wear information and the trigger number corresponding to the second wear information, the trigger number that is smaller than the other trigger numbers is confirmed as the first maintenance point, and the trigger number that is smaller than the other trigger numbers and larger than the trigger number corresponding to the first maintenance point is confirmed as the second maintenance point.

[0136] It can be understood that confirming the first inspection point and the second inspection point is to confirm that the elevator switch needs to be inspected or replaced after being triggered by the trigger number corresponding to the first inspection point, and the inspection or replacement needs to be completed before the trigger number corresponding to the second inspection point is triggered. Confirming the first inspection point and the second inspection point can provide a basis for subsequent steps to ensure the safety of the elevator.

[0137] For example, assuming that the trigger number corresponding to the first resistance critical information is 8000, the trigger number corresponding to the second resistance critical information is 8500, the trigger number corresponding to the first wear information is 7000, and the trigger number corresponding to the second wear information is 9000, then the trigger number corresponding to the first maintenance point is 7000, and the trigger number corresponding to the second maintenance point is 8000.

[0138] S233, confirming the numerical value interval reflected from the first maintenance point to the second maintenance point as a critical maintenance interval.

[0139] It can be understood that confirming the numerical value interval reflected from the first maintenance point to the second maintenance point as the critical maintenance interval can provide a reference for the maintenance timing of the elevator switch.

[0140] S234, confirming the durability critical number and the critical maintenance interval as durability analysis information.

[0141] It can be understood that confirming the critical durability times and critical maintenance intervals as durability analysis information can provide a basis for subsequent steps.

[0142] S300, obtaining a durability analysis report based on the durability analysis information; wherein the durability analysis report reflects the durability of the elevator switch.

[0143] It can be understood that the durability analysis report can be obtained based on the durability analysis information by sending the durability analysis information to the user and then receiving data sent back by the user, or by analyzing the critical durability times, etc., but is not limited thereto.

[0144] In one possible implementation, see Figure 6 , S300, obtaining a durability analysis report based on the durability analysis information, including:

[0145] S310, obtaining a preset triggering number; wherein the preset triggering number reflects the number of times the elevator switch is expected to be triggered.

[0146] It is understandable that the way to obtain the preset trigger times may be to receive data transmitted by the user, or to confirm the number of times the elevator door is opened and closed as the preset trigger times, but is not limited thereto. Obtaining the preset trigger times can provide a basis for subsequent steps.

[0147] S320, judging whether the preset triggering times are greater than the durability critical times; if the preset triggering times are greater than the durability critical times, obtaining quality analysis information reflecting that the durability of the elevator switch is unqualified.

[0148] It can be understood that judging whether the preset triggering times is greater than the critical durability times is to judge whether the maximum triggering times of the elevator switch without affecting the operation of the elevator meets the user's expectations. If the preset triggering times are greater than the critical durability times, it means that the maximum triggering times of the elevator switch without affecting the operation of the elevator do not meet the user's expectations. Obtaining quality analysis information reflecting the unqualified durability of the elevator switch can provide a basis for subsequent steps.

[0149] S330: If the preset triggering times are less than or equal to the durability critical times, quality analysis information reflecting that the durability of the elevator switch is qualified is obtained.

[0150] It can be understood that if the preset triggering times are less than or equal to the durability critical times, it means that the maximum triggering times of the elevator switch without affecting the operation of the elevator meet the user's expectations. The quality analysis information reflecting the qualified durability of the elevator switch can provide a basis for subsequent steps.

[0151] S340, confirming the quality analysis information, the critical number of durability times and the critical maintenance interval as a durability analysis report.
