Abstract

The invention relates to the field of elevator safety performance parameter measurement, in particular to an elevator safety performance parameter measurement device and method and application. The elevator safety performance parameter measurement device comprises a weighing body and a handheld terminal, the weighing body is provided with a weighing sensor, a transmitting end power supply module is connected with an analog-to-digital conversion module through the weighing sensor, and the analog-to-digital conversion module is connected with a wireless transmitting module through a transmitting end single-chip microcomputer. The handheld terminal comprises a receiving module, the receiving module is connected with a display module through a receiving end single-chip microcomputer, and a receiving end power supply module is connected with the receiving end single-chip microcomputer. The transmitting module is connected with the receiving module in a wireless transmission mode. The device is convenient to carry, a load does not need to be carried in the whole testing process, the measuring process is simple and fast, two persons can complete the testing process, the testing instrument is easy to operate, the device is divided into a measuring end and the handheld terminal which are in transmission connection through wireless signals, testing results are all numerical values and are directly displayed, data are accurate, and traceability is achieved.

Description

technical field [0001] The invention relates to the field of elevator safety performance parameter measurement, in particular to an elevator safety performance parameter measurement device, measurement method and application. Background technique [0002] Existing elevator safety performance tests (balance factor, weighing, traction capacity, load test, etc.) rely entirely on the actual weight loaded by the elevator for testing, which is slow, poor in accuracy, and seriously time-consuming and labor-intensive. [0003] The process of measuring the balance coefficient is to manually carry heavy objects of different weights and place them in the elevator car, and then use the method of measuring current during the operation to measure. This measurement method has a large human error and is too time-consuming and laborious.

[0002] Existing elevator safety performance tests (balance factor, weighing, traction capacity, load test, etc.) rely entirely on the actual weight of the elevator for testing, which is slow, poor in accuracy, and seriously time-consuming and laborious.

[0003] The balance coefficient measurement process is to manually carry heavy objects of different weights and place them in the elevator car, and then use the method of measuring current to measure during the operation process. This measurement method has a large human error and is too time-consuming and laborious.

[0004] The two experiments of traction capacity and load test not only need to carry heavy objects for testing, but also the result of the test is only to see the steel wire rope slipping on the host machine as the basis for judgment, without data support, and many elevators are now equipped with overload protection, which leads to this method is more difficult to implement

[0005] The weighing experiment needs to carry heavy objects of actual weight in the elevator supervision and inspection, which is time-consuming and laborious, and the elevator weighing device will shift after a period of use, and needs to be calibrated again. It is not only time-consuming and labor-intensive to carry heavy objects in a normal elevator can also have a serious impact on users
