Technical Field

The invention relates to the technical field of elevator running quality monitoring, in particular to a monitoring system and a monitoring method for evaluating elevator running quality by using time dimension.

Background

The evaluation of the quality of elevator operation involves a number of components of the elevator system. Also, elevator ride quality factors will vary as occupants desire different comfort levels for the elevator. In the field of elevator operation and maintenance, how to comprehensively evaluate the elevator operation quality, reasonably set maintenance priority and clear responsibility except the elevator operation quality is greatly helpful for improving the elevator maintenance efficiency and riding comfort.

currently, the evaluation of elevator operation quality relies on data collection and condition alarm triggering by different types of sensors. There are multiple technical advices in this field to synthesize different types of sensor information in a weight mode and give a method for triggering the running quality alarm, namely, an evaluation mode of superposing and summing all abnormal data detected by different types of sensors in the elevator, and when the data obtained by superposing and summing are abnormal, a monitoring person informs a maintenance person to maintain the elevator. However, the evaluation method has the following defects that firstly, technical parameters which are of various types and influence the running quality of the elevator cannot be uniformly presented; secondly, the quality state of the elevator operation cannot be comprehensively and objectively reflected; thirdly, the evaluation of the running quality of the elevator, which is a factor lacking in time, will affect the credibility and the foresight of the evaluation result.

in addition, comparing the operating quality of different types and brands of elevators is a challenge in elevator safety supervision. The direct weight superposition of the raw data of the sensors leads to deviations in the evaluation of the elevator operating quality.

As shown in fig. 1, a monitoring system for evaluating the running quality of an elevator in a time dimension comprises a running quality monitoring unit, a sensing unit 1 and a central server;

The sensing unit 1 is arranged in the elevator car and used for collecting elevator running quality data and sending the elevator running quality data to the running quality monitoring unit;

The running quality monitoring unit is arranged in the elevator car and used for receiving the running quality data of the elevator and sending the running quality data to the central server;

the central server is used for receiving the sent elevator running quality data, obtaining the total time length of the elevator in normal running service and the total time length of the elevator alarm, calculating the time percentage of the elevator service according to the total time length of the elevator in normal running service and the total time length of the elevator alarm, obtaining elevator running quality monitoring data according to the time percentage of the elevator service, and sending the elevator running quality monitoring data to the elevator running monitoring service terminal 2.

The operation quality monitoring unit is connected with the central server through a data transmission link to obtain the relevant detection parameter setting of the elevator; and begins to accumulate the time that the elevator is placed into service. The operation quality monitoring unit uses a plurality of paths of data transmission links, and besides a special data transmission link of an elevator shaft, the operation quality monitoring unit is also provided with a backup data transmission link which uses WIFI and a mobile data network as backup data and is used for judging whether the communication between the central server and the operation quality monitoring unit breaks down or not.

when the elevator is installed, sensing data alarm thresholds of an acceleration sensor, an inclination angle sensor, a temperature and humidity sensor and an air quality sensor are set according to the type and the technical parameters of the elevator. An alarm threshold value is set by combining the specific elevator condition on the principle of following the relevant technical standard of the industry, finding the elevator operation quality fault in time and taking the elevator comfortably.

In the running process of the elevator, the acceleration sensor, the inclination angle sensor, the temperature and humidity sensor, the air quality sensor, the video camera and the noise recorder respectively collect the acceleration, the inclination angle, the temperature and humidity, the air quality, the video in the elevator and the running quality data of the elevator detected by the noise recorder in a time unit and transmit the data to the running quality monitoring unit; the operation quality monitoring unit transmits the detected elevator operation quality data to the central server to judge whether the detected elevator operation quality data exceeds a preset alarm threshold value.

For more complicated elevator quality scenes, images in the elevator can be acquired in real time through the connection of the video camera arranged right above the elevator door and the third-party camera communication connection interface arranged in the operation quality monitoring unit with the third-party camera, and then the images are analyzed to obtain the real state of the elevator, such as the closing state of the elevator door, the display of the elevator floor and the like.

When the operation quality data of the elevator, which is contrasted and detected by the operation center server, exceeds an alarm threshold value or a video analysis result is judged to be an alarm state, an elevator service fault accumulated time counter in the center server starts to accumulate the alarm time of the elevator, the alarm state disappears, and the elevator service fault accumulated time counter stops accumulating the alarm time of the elevator; meanwhile, when the elevator starts to be put into operation service, the elevator total service operation time counter in the central server starts to time.

the operation quality monitoring unit continuously uploads the detected elevator operation quality data, the video pictures in the elevator, the operation service time and the elevator quality failure time to the central server, the central server collects the operation quality data of all elevators, the time percentage of elevator service is calculated according to the total time length of the elevator in normal operation service and the total time length of the elevator alarm, the elevator operation quality monitoring data is obtained according to the time percentage of the elevator service and is sent to the mobile terminal or the PC terminal, and the mobile terminal or the PC terminal pushes the elevator information lower than a specific numerical value to the elevator responsibility responsible person and the maintenance person to remind the maintenance.

the central server obtains elevator running quality monitoring data according to the percentage of time of elevator service to classify emergency elevator fault information, and the elevator fault information is immediately pushed to elevator responsibility managers and maintenance staff through the mobile terminal or the PC terminal until the persons confirm the alarm. Besides providing fault alarm, the central server also provides additional information, such as the floor where the elevator has faults and video pictures in the elevator, so that operation and maintenance personnel can conveniently and quickly locate the fault reasons.

step D: when the elevator operation quality data is alarmed, timing by an elevator service fault accumulated time counter, and executing the step F;

Step E, when the elevator operation quality data is not alarmed, the elevator service fault accumulated time counter is not timed, and step F is executed;

And F, calculating the time percentage of the current elevator service = 100% - (elevator service fault accumulated time/elevator total service running time) x 100%, calculating the time percentage of the current elevator service, and returning to the step C to enter the next cycle.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
