Problems solved by technology

Except for the GIS positioning method, other methods indirectly prove whether the maintenance personnel have arrived at the scene. In practical applications, it is often found that some lazy maintenance personnel cheat and send back, so that the confirmation is distorted.
As for the more accurate GIS positioning method, it is suspected of violating personal privacy first, and on the other hand, it is impossible to distinguish the elevators in the same machine room.
[0005] Furthermore, is there maintenance after the maintenance personnel arrive at the scene? At present, we can only send inspectors to the scene to confirm, which is a waste of manpower and material resources, and it is difficult to confirm every time.

Embodiment

[0023] Add the following functions to the existing elevator control system:

[0024] S1: Record the connection time Tn0 and duration Tn1 of each maintenance tool;

[0025] S2: record each stop switch off time Tn2 and duration Tn3;

[0026] S3: record each safety circuit disconnection time Tn4 and duration Tn5;

[0027] S4: Record the time Tn6 and duration Tn7 of each elevator power failure;

[0028] S5: Record the start time Tn8, duration Tn9, lowest order Fn0 and highest order Fn1 of each maintenance operation;

[0029] S6: Record the start time TnA, duration TnB, lowest order Fn2 and highest order Fn3 of each emergency electric operation;

[0030] S7: Record the start time TnC, duration TnD, lowest order Fn4 and highest order Fn5 of each maintenance device action;

[0031] S8: transfer the record value back to the company server and archive it;

[0032] S9: The server compares the sizes of Tn0, Tn2, Tn4, Tn6, Tn8, TnA, and TnC, and sets the smallest value as the mainten...

Abstract

The invention discloses a confirmation method for elevator maintenance, which is characterized in that: the changes of each signal in the elevator maintenance process are recorded, the maintenance information is made according to the change data of each signal, and the maintenance information is used to confirm the status of the maintenance operation Implementation. The present invention changes the flaws of maintenance operations that can only be confirmed through indirect methods in the past, and uses on-site maintenance information to confirm maintenance operations, making supervision and management more authentic and reliable.

Description

Technical field: [0001] The invention relates to the technical field of elevators, in particular to a method for confirming elevator maintenance operations. [0002] technical background: [0003] Elevators are special equipment and require regular and / or irregular maintenance during use. However, the elevators are scattered in buildings outside the company. Have the maintenance personnel arrived on site after accepting the task? Did you work as required after arriving at the site? It has been an issue that regulators and industry personnel have been struggling to explore. [0004] At present, it is only possible to confirm whether the maintenance personnel have been to the site. The methods include asking the owner to sign a receipt, the maintenance personnel checking in at a fixed location, sending back site pictures, and GIS positioning. Except for the GIS positioning method, other methods indirectly prove whether the maintenance personnel have arrived at the site. In pr...
