Description

TECHNICAL FIELD

[0001] The present application relates to the field of elevators, and in particular to a control method and device for an autonomous functional body of an elevator. BACKGROUND

[0002] Currently, the maintenance of elevators and the actual working conditions of components are mostly obtained by manual visual inspection or through the use of dedicated sensors. Manual visual inspection requires maintenance personnel to approach the components to be inspected, which is inefficient and labor-intensive, and in some special cases, it can also pose a danger to the safety of maintenance personnel, or even in some cases, manual visual inspection cannot be implemented because the maintenance personnel are not allowed to approach, such as understanding the actual situation of the rolling guide shoe under the high-speed running state of the elevator, which is impossible to achieve by manual visual inspection. Sensor detection can indeed achieve the detection of the actual working conditions of components without the need for maintenance personnel to approach the components to be inspected, but it requires the use of dedicated sensors for each component to be inspected, which is not ideal in terms of implementation cost and complexity. In addition, since the components to be inspected do not need to be continuously detected, they only need to be inspected when certain conditions are met (such as when the use time exceeds a threshold, or when there is a significant change in the performance of the elevator, such as when the car vibration significantly increases during elevator operation, it may be necessary to monitor the rolling guide shoe), therefore, the sensor method has the disadvantages of high cost, high complexity, and low utilization.

[0003] On the other hand, the use of autonomous flying bodies with sensors can achieve detection and monitoring of elevators, such as patent document 1 (application number: 201780033494.5), patent document 2 (application number: 201810153884.2), patent document 3 (application number: 201810439128.6), and patent document 4 (application number: 201811424942.7). These technologies use the sensors (usually cameras) of autonomous flying bodies to collect images of elevators and upload the images to a remote monitoring center, and the solution in patent document 1 further proposes that the access part of the elevator equipment decides whether to authorize the autonomous flying body to enter the shaft. Therefore, the autonomous flying body can be used to implement maintenance of components to be inspected. However, the aforementioned prior art has the following shortcomings:

[0004] I. The monitoring object is limited to shaft monitoring, and it is impossible to achieve monitoring of other components of the elevator (mainly the car);

[0005] II. The elevator car is required to be in a stationary state, and it is impossible to achieve monitoring tasks for elevators or their components in a dynamic state, such as the working conditions (such as sound, vibration, and deviation) of the rolling guide shoe under normal operation of the elevator;

[0006] III. Since the elevator is required to be in a stationary state, it does not involve the cooperation of the autonomous flying body with the elevator;

[0007] Four, whether to grant the autonomous flying body to enter the hoistway is determined only according to code matching (paragraph

[0014] of Patent Document 1), and whether the current state of the elevator is suitable for the entry of the autonomous flying body is not considered;

[0008] Five, whether the current state of the monitoring object meets the monitoring requirements (referring to the limitation on the working state of the monitoring object) is not considered.

[0009] The above deficiencies of the prior art not only greatly limit the types and ranges of the monitoring objects, but also cannot realize the monitoring of the monitoring objects in a dynamic state.

[0010] Therefore, how to realize the monitoring of the elevator or its components without limiting the types and ranges and without limiting the state has become a technical problem to be solved. SUMMARY

[0025] Preferably, when the control instructions obtained in step B3 are not unique, step B4 selects the control instruction with the least impact on the elevator operation and passenger boarding experience and sends it to the elevator control device.

[0026] Preferably, when the result of step B5 is yes, between step S8 and S9, there is further included a step C1 of sending an end instruction to the elevator control device to end the control instructions when the monitoring task is completed.

[0027] Preferably, if the result of the judgment of step B5 is yes, then when the monitoring task ends, the step C1 adjusts the control instruction to gradually reduce its influence on the elevator operation and the passenger's boarding experience to zero, and then completely ends the control instruction.
