Problems solved by technology

[0005] 1) Mechanically adopt fixed troubleshooting guidance, which lacks pertinence and directionality for different working conditions on different sites, which may lead to heavy on-site maintenance burden, long time, poor effect, and affect the normal use of elevators by customers for a long time;
[0006] The traditional method of going to the scene to obtain data and check the elevator after a fault occurs, because there is usually a long delay from the fault occurrence to the relevant personnel arriving at the scene, so it may happen that the elevator control CPU is restarted, resulting in partial fault data loss, or faulty parts It has been recovered, resulting in "everything is normal in the elevator after arriving at the scene", it is difficult to restore the scene of the fault, and the scene of the fault becoming an unsolved case makes it difficult to troubleshoot
[0007] 2) The traditional troubleshooting guidance documents only list the reasons to be checked, and the time spent on checking and the results of the checking greatly depend on the experience of the on-site elevator maintenance personnel
[0008] 3) The troubleshooting methods and experience of different faults are the wealth accumulated by the enterprise. The traditional troubleshooting methods are difficult to realize the feedback of on-site troubleshooting experience or the in-depth extraction of experience knowledge, so it is not conducive to the enrichment and update of on-site troubleshooting experience and promotion
[0009] 4) In order to improve the effect of fault diagnosis and fault location, sensors and other detection equipment can only be passively added, which increases the cost of the product

Embodiment 1

[0041] Such as figure 1 As shown, the simplest embodiment of the method described above: the system is composed of a fault information acquisition unit, a fault auxiliary information acquisition unit, and an analysis and processing unit. The fault information obtaining unit is used to obtain information that characterizes the fault of the elevator, the auxiliary fault information obtaining unit is used to obtain relevant auxiliary information of the fault of the elevator, and the analysis and processing unit is used to obtain the fault information obtained by the fault information obtaining unit and the The auxiliary fault information of the elevator acquired by the auxiliary fault information acquisition unit analyzes and deduces the suspected cause of the fault of the elevator, and generates a troubleshooting guide according to the analysis and deduction results.

[0042] The analysis processing unit further includes an enumeration subunit, a screening subunit, a sorting sub...

Embodiment 2

[0063] Such as figure 1 As shown, the system configuration is the same as that of Embodiment 1.

[0064] The fault scenario is also similar to that of Embodiment 1, but since the safe start condition is met after the fault, refer to figure 2 shown. Compared with the method in Embodiment 1, the troubleshooting guidance method of this embodiment only adds steps between steps A2 and S5:

[0065] A1. According to the fault information, judge whether the fault is a persistent fault. If so, go to A2, otherwise go to step S5; it is currently judged that the fault has not been eliminated, and then go to A2.

[0066] A2. Determine whether the elevator can be restarted safely, if so, go to A3, otherwise go to step S5;

[0067] Actively diagnose the current elevator health, judge that the elevator can be restarted safely, and turn to A3;

[0068] A3. On the premise of ensuring the safety of the elevator, actively start the diagnostic operation to obtain auxiliary information after t...

Embodiment 3

[0074] Such as image 3 As shown, the system structure is based on Embodiment 1, and an optimization sub-unit is added to the analysis and processing unit of the system. The optimization subunit is responsible for optimizing the expert knowledge base according to the maintenance process and / or results fed back by the on-site maintenance personnel after completing the elevator maintenance.

[0075] And the failure scenario is exactly the same as that of Embodiment 1, so refer to figure 2 shown. Compared with the method in Embodiment 1, the troubleshooting guidance method of this embodiment only adds steps between steps S5 and S6:

[0076] A6. The on-site maintenance personnel feed back the maintenance process and / or results after completing the elevator maintenance, and the system optimizes the expert knowledge base according to the feedback information.

[0077] After the on-site personnel completed the maintenance with reference to the troubleshooting guide, they found th...

Abstract

The invention discloses an elevator failure eliminating guidance method. The method comprises the steps of obtaining elevator failure information; listing all suspected reasons of the failure information, using auxiliary information during elevator failures for screening the suspected reasons, eliminating the suspected reason which is determined not to cause the failure at the time, and using theauxiliary information and / or existing expert knowledge before the elevator failure for evaluating and the eliminating the small-probability suspected reasons; and sorting the remaining suspected reasons, and generating the failure eliminating guidance for the elevator failure at the time. Through the method, the failure eliminating guidance accuracy can be improved, the site operation can be simplified, the elevator stop time can be reduced, the failure eliminating efficiency is improved, and the technical requirement for the site maintenance personnel can be reduced. In addition, the invention provides an elevator failure eliminating guidance system.

Description

technical field [0001] The invention relates to elevators, in particular to an elevator troubleshooting guidance system and method. Background technique [0002] Generally speaking, in the daily use of the elevator, when the elevator fails, the on-site maintenance personnel will repair the elevator according to the failure phenomenon of the elevator and the fault code currently displayed by the elevator. After getting the fault code of the elevator, maintenance personnel usually consult the fault manual manually on site or request remote assistance to obtain the fault content corresponding to the fault code of the elevator, and then repair the elevator according to the fault content. Since the number of fault codes preset by the elevator is usually large, and multiple fault codes often appear at the same time when the elevator fails, the manual inspection method is time-consuming, laborious and inefficient. [0003] In response to this problem, the Chinese invention patent ...
