Description

Technical Field

[0001] The present invention relates to the technical field of elevator noise test and analysis, and particularly relates to an elevator noise test auxiliary analysis and management system. Background Art

[0002] With the rapid development of the urbanization process, elevators, as key equipment for vertical transportation, play an indispensable role in people's daily life and work. The noise problem generated during the operation of elevators has gradually become the focus of people's attention. Elevator noise not only affects the quality of life of residents, leading to neighborhood disputes, but also may pose potential hazards to the physical and mental health of users. Residents' dissatisfaction with the elevator noise in their communities is on the rise, and some of them even experience symptoms such as insomnia and anxiety.

[0003] Currently, the testing of elevator noise mainly relies on the traditional manual single-point sampling operation method with a handheld sound level meter, which has problems such as low efficiency, poor accuracy, and non-standard data recording. At the same time, the data analysis and management of noise lack systematicness and scientificity, with low data analysis efficiency. Existing test reports are mostly PDF static documents, lacking the ability of multi-dimensional data correlation analysis, and it is difficult to quickly and accurately locate the noise source and formulate effective solutions. In addition, the data formats of third-party testing agencies are not unified, and 30% of the test reports have difficulties in data traceability. With the rapid development of technologies such as the Internet of Things, big data, and artificial intelligence, developing an intelligent elevator noise test auxiliary analysis and management system has important practical significance and application value. It can real-time monitor and analyze elevator noise data, accurately locate the noise source through a friendly operation interface and modular data calculation, and conduct compliance judgment, providing a scientific basis for elevator inspection and maintenance, effectively reducing elevator noise, and improving the quality of life of residents.

The number of test points is not less than 3, and sound measurement sensors are set at the test point positions;

[0013] At each test point, obtain the background noise respectively when the drive host is in the stop state and record the background noise;

[0014] When the elevator runs at the rated speed, measure the running noise at each test point and record the measured values.

[0015] Further, when measuring the background noise and running noise at each test point, other equipment in the machine room is in a stationary state.

[0016] Further, the method for acquiring the car interior noise data by the car interior noise acquisition module is as follows:

[0017] Select the test point position, and a sound measurement sensor is set at the center of the car interior and 1 - 1.5 meters from the ground;

[0018] Close the car door, obtain the background noise when the elevator is in the stop state, and record the background noise;

[0019] When the elevator runs at the rated speed throughout the whole journey, measure the maximum measured value of the noise inside the car during the upward running process, and use the same method to record the background noise and the maximum measured value during the downward running of the elevator.

[0024] Finally, obtain the door opening and closing noise value of the test car door inside the car, the background noise value of the car door test point, as well as the maximum value of the landing door opening and closing noise, the landing where the maximum value of the landing door opening and closing noise is located, and the background noise value of the test point of the maximum value of the landing door opening and closing noise.

[0025] Furthermore, the method for the noise acquisition module at the landing of the machine - room - less elevator to obtain the noise data at the landing of the machine - room - less elevator is as follows:

[0026] Select the test point position, select the landing door at the landing closest to the installation position of the driving host, at the middle of the opening width of the landing door, and set a sound measurement sensor at a horizontal distance of 0.5 m from the door leaf and a vertical distance of 1.5 m from the landing floor;

[0027] At each test point, measure the background noise in the stopped state of the elevator; when the elevator runs at the rated speed throughout the whole journey upward, measure the maximum value of the noise at the landing door during the running process of the elevator at the rated speed from after the departure - end door is closed to before the arrival - end door is opened, record the measured landing and the maximum measured value of the noise at the landing door at each test point, and use the same method to measure and record the background noise and the maximum measured value of the noise at the landing door during the downward running of the elevator.

[0028] Furthermore, the specific process of the noise analysis and determination module is as follows:

[0029] When the difference between each measured value and the corresponding background noise value is greater than 10 dB(A), no correction is required; when the difference is less than or equal to 10 dB(A), correct it in the following way:

[0030]

[0031] For the noise inside the car, the noise of opening and closing the door, and the noise at the landing door of a machine-roomless elevator, take the maximum measured value after correction, compare the maximum value with the corresponding value in the following table, and if it does not exceed the value range, it is qualified.

[0032]

[0033] Furthermore, the elevator noise determination signal is determined according to the total test results of the machine room noise, the noise inside the car, the noise of opening and closing the door, and the noise at the landing door of a machine-roomless elevator. If the machine room noise, the noise inside the car, the noise of opening and closing the door, and the noise at the landing door of a machine-roomless elevator are all qualified, the noise test result is qualified. If any one of the tests is unqualified, the noise test result is unqualified, and it is visually displayed in the determination report of the determination report generation module.

[0034] Beneficial effects:

[0035] 1. The elevator noise test auxiliary analysis and management system designed by the present invention can obtain the noise data at each test point of the elevator according to the elevator equipment to be tested and analyzed, correct it with the background noise, and compare the corrected maximum noise value with the preset value to determine whether the noise is qualified. According to the determination result, a test report is generated. The present invention can monitor and analyze elevator noise data in real time, accurately locate the noise source through a friendly operation interface and modular data calculation, and conduct compliance determination, providing a scientific basis for elevator inspection, testing, maintenance and repair, effectively reducing elevator noise, and improving the living quality of residents.

[0036] 2. When testing the machine room noise of the present invention, multiple test points are selected for testing. After the measured value of each test point is corrected, the average value is compared with the threshold value to judge the qualification. Selecting the average value for multi-point testing is more in line with the characteristics of machine room noise. For the noise inside the car, the noise of opening and closing the door, and the noise at the landing door of a machine-roomless elevator, the corrected maximum measured value is taken for qualification judgment, because for the noise inside the car, the noise of opening and closing the door, and the noise at the landing door of a machine-roomless elevator, each measurement point needs to meet the requirements.
