Problems solved by technology

Obviously, the acceleration threshold is closely related to the rated acceleration. The rated acceleration cannot be known in advance for the application of Company A, which makes the setting of the acceleration threshold a problem. On-site setting, which will obviously bring a lot of inconvenience to on-site practice, and improper setting may also cause misjudgment;
[0006] c. For judging whether there are positive acceleration segments and negative acceleration segments in the detection results of the acceleration sensor, it cannot be correctly judged when running in special modes such as maintenance, which will bring great errors to the statistical results

Embodiment 1

[0043] figure 1 As shown, the elevator starting times measuring device includes:

[0044] The door zone sensor is composed of the detected body installed in the shaft and the detection body installed on the car, and is used to detect the door zone signal when the elevator car enters and leaves the door zone;

[0045] a waveform analysis unit, configured to analyze the door zone signal output by the door zone sensor, and output the motion stage of the elevator car during a door zone startup process;

[0046] a speed calculation unit for calculating the moving speed of the elevator car during said movement phase;

[0047] A judging unit, configured to judge whether the elevator has completed a startup according to the motion phase output by the waveform analysis unit and the moving speed corresponding to the motion phase output by the speed calculation unit;

[0048] The counting unit determines whether to add 1 to the counting result according to the judging result of the jud...

Embodiment 2

[0054] Based on the measuring device for the number of elevator starts in Embodiment 1, the detection body includes an upper detector and a lower detector arranged on the elevator car along the direction of the hoistway, and the waveform analysis unit The combination of the detection signals output by the detectors analyzes at least two different forward and backward movement stages of the elevator car in the first movement stage and the second movement stage of a door zone start process.

[0055] Preferably, the upper detector is arranged on the top of the car; the lower detector is arranged on the bottom of the car.

[0056] In order to realize the detection of the leveling position, two detectors are usually arranged at a certain distance, and the object to be detected and the detector can be as disclosed in Chinese patent application CN200680055531.4 and Chinese patent document CN1492832A.

Embodiment 3

[0058] Based on the measuring device for the number of elevator starts in Embodiment 2, the judging unit judges whether a new first motion stage is received according to the second motion stage output by the waveform analysis unit, and further judges when the judgment result is yes Corresponding to the magnitude relationship between the moving speed corresponding to the new first motion stage and the corresponding threshold value, it is determined whether the elevator completes a startup.

[0059] Preferably, the new first motion stage is at least one of the front section of the door zone, the stop section and the rear section of the door zone, and the judging unit When the moving speed is less than the corresponding threshold, it is determined that the elevator has completed a start.

[0060] Preferably, the judging unit preferentially adopts the stop segment as the new first motion stage.

[0061] Considering that when the elevator car passes a certain floor but does not st...

Abstract

The invention discloses an elevator starting frequency measuring device, which is characterized in that a door area sensor consists of a detected body arranged in a shaft and a detection body arranged on a car, and is used for detecting a door area signal when the elevator car enters and leaves a door area; a waveform analysis unit is used for analyzing a door area signal and outputting a movement stage of an elevator car in a primary door area starting process; the speed calculation unit is used for calculating the moving speed of the elevator car in the moving stage; a judgment unit is used for judging whether the elevator is started once or not according to the movement stage and the movement speed corresponding to the movement stage; and the counting unit determines whether to add 1 to the counting result according to the judgment result of the judgment unit. According to the device for measuring the starting times of the elevator, a new sensor does not need to be additionally arranged, and the starting times of the elevator can be conveniently and quickly measured at low cost under the condition of not depending on relevant information of an elevator control screen.

Description

technical field [0001] The invention relates to elevator control technology, in particular to an elevator starting times measuring device. Background technique [0002] The number of elevator starts is an important parameter to evaluate the actual use of the elevator after the elevator is installed and put into use. At present, the number of elevator starts mostly comes from the elevator control panel. For example, Document 1 (CN201410301206.8) uses the elevator operation record information when calculating the number of elevator starts as the elevator maintenance needs. However, the counting device for the number of starts of the elevator in Document 1 relies on the elevator operation record information from the elevator control panel for the statistics of the number of elevator starts. statistics and display of elevator usage such as the number of elevator starts) is not applicable. [0003] In response to this problem, Document 2 (CN201880096092.4) proposes to use an el...
