Description

A kind of elevator running monitoring method

technical field

The invention relates to the field of elevators, in particular to a method for monitoring elevator operation.

Background technique

Elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of rigid tracks perpendicular to the horizontal plane or with an inclination angle of less than 15° to the plumb line. At the end of the 20th century, the elevator used permanent magnet synchronous traction machine as the power, which greatly reduced the area of the machine room, and had the advantages of low energy consumption, energy saving and high efficiency, and fast lifting speed, which greatly promoted the development of real estate to the direction of super high-rise.

At present, the car elevator needs to monitor the running state of the car when it is running. The monitoring of the running state of the elevator car (whether it is faulty or not) is one of the most important links in the intelligent elevator operation and maintenance process. At present, the monitoring of the running status of the elevator car generally relies on the acquisition of sensors at specific positions, such as obtaining the position (floor, height) information of the elevator car through air pressure sensors or infrared sensors, and obtaining the running speed and acceleration of the car through accelerometers, etc. Information, through limit switches, counters, etc. to obtain the door opening and closing status, times and other information, through the camera to obtain status data such as the number of people in the car and whether people are trapped.

The terminals that obtain the elevator running status information are all electronic devices or electronic devices, and the service life, environmental interference, self-failure or operation logic errors, etc., will lead to errors in the obtained monitoring data. The traditional elevator car monitoring system is connected with the control system. When the monitoring system fails or has errors, it will affect the normal operation and control of the elevator, and cannot effectively feedback the running state of the elevator car, making the position, speed, acceleration and other parameters. The potential risks of elevators cannot be assessed in time, which introduces unstable factors to the safety of elevator operation. At present, some elevators use two sets of monitoring terminals or systems, that is, an additional set of redundant equipment is added to verify the monitoring information and prevent the failure or error of the monitoring equipment from causing safety problems. However, this method is costly and requires additional installation. , operation and maintenance are inconvenient.

Description of drawings

FIG. 1 is a schematic block diagram of the flow of the present invention.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figure 1, a kind of elevator operation monitoring method, obtains the regular operation data information when the elevator is running in real time; Stores the normal operation basic data information of the elevator; Carry out the calibration test operation control to the elevator, and obtain the calibration test data information; Cross-comparison and verify all or part of the normal operation data information, normal operation basic data information and verification test data information, and give an early warning when the comparison and verification results are abnormal.

The normal operation basic data information of the elevator is preset and stored, and the real-time normal operation data information and verification test data information are obtained, and all or part of the normal operation data information, normal operation basic data information and verification test data information are cross-compared. For verification, part of the information can also be verified multiple times, so that the elevator running status or monitoring information of the monitoring terminal or monitoring terminal operation information can be verified directly or indirectly. There is no need to add redundant monitoring terminals or systems, and the cost is low and Easy to use and high efficiency.

Specifically, the routine operation data information is acquired by the existing monitoring terminal of the elevator, including location information such as the floor where the elevator is located, speed information when the elevator travels from any floor to any other floor, door opening and closing information, and camera collection image information, etc. In the regular running data information collected in real time, obtain the floor change information and the speed information of the elevator when it is actually running, calculate the running speed of the elevator according to the time interval information of the floor change, and compare the running speed calculated by the floor change with the obtained real-time running speed of the elevator. The speed information is compared and verified. In reality, the real-time speed information of the elevator includes the acceleration information of the acceleration section and the running speed information of the smooth running section. In the actual comparison, the speed of the acceleration section and the speed of the smooth running section are calculated as the average speed and the speed calculated by the floor change is compared. The comparison, or the speed of the smooth running section and the speed calculated by the floor change are within the preset differential speed threshold, that is, the verification result is considered correct. This process can mutually verify the normal operation and monitoring of the floor infrared sensing equipment, accelerometer and other equipment.

The floor change information in the conventional operation data information can also be compared and verified with the image information collected by the camera in the car. Identify and acquire the floor change information corresponding to the trigger button in the car in the image, and compare and verify the conventionally acquired floor change information according to the identified floor change information. That is, when there is a passenger in the car, the target floor information corresponding to when the passenger presses the button to turn on is obtained through image recognition, and the information that the button is turned off is obtained through image recognition after the elevator reaches the floor, and the above information is combined with floor detection. The floor information obtained by the sensor is compared. If the floor information obtained by the floor detection sensor is consistent with the target floor information obtained by image recognition when the button light is off, it means that the floor detection sensor is running and monitoring normally.

Compare the image information collected by the camera in the car with the car door switch information in the conventional operation data information, identify and obtain the switch information of the car door in the image, and perform a routinely obtained switch according to the identified door switch information. The door information is compared and verified. Obtain the door opening and closing information and time information in the image through image recognition, and calculate the door opening and closing speed information according to the time information, and compare the recognized door opening and closing information and door opening speed information with the door opening and closing information detected by the door opening sensor. In contrast, if they are consistent, it means that the door opening and closing detection sensing equipment is running and monitoring normally.

Specifically, the daily operation data of the elevator operation is acquired and stored, the daily data is periodically counted and analyzed, and the empty window period of the elevator operation is obtained, and the elevator is checked and tested for operation control during the empty window period. Empty window period refers to a certain period of time, such as every day, every week, every month, etc., the elevator usage rate is the lowest in a certain period of time, and the calibration test operation is carried out in this period of time, such as the time period around 3:00 in the morning Almost no one uses the elevator in this time period. During the calibration test operation during this time period, it can fully avoid affecting the use of passengers. If there is a passenger recruiting the elevator during the verification test operation, the verification test operation will be interrupted and the elevator recruiting command will be responded.

During the empty window period, control the elevator to execute the specified command action according to the verification test requirements, obtain the image verification identification information of the camera in the car, and compare and verify the image verification identification information with the instructions required by the verification test. If the verification test command requires the elevator to run to a certain floor, the floor number displayed in the car is obtained according to the image recognition to verify the accuracy of the image recognition and the normal operation of the camera. In addition, when the elevator is out of service, you can control the button in the elevator car to light up or the display screen to display the floor where the car is currently located, or control the display screen to display different numbers but not run the elevator, and perform the operation according to the display content obtained by image recognition. Compare and verify whether the camera is working normally, the recognition rate, etc. This method can be completed in a relatively short period of time.

During the empty window period, control the elevator to run from any floor to each floor according to the verification test requirements, calculate the running speed according to the statistical running time, control the car door to carry out continuous door opening and closing test and count the door opening and closing speed, and calculate the running speed. The speed or door opening and closing speed is compared and verified with the speed information or anti-pinch door opening and closing speed information in the basic data information of normal operation, so as to test the response of the elevator operation to the command.

In practice, the normal operation basic data information includes the acceleration information, speed information and door opening and closing speed information corresponding to the elevator running from any floor to each floor. The information is compared and verified to verify whether there is any deviation between the acquired monitoring data and test data and the original data.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, but that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments are to be regarded in all respects as illustrative and not restrictive, and the scope of the invention is to be defined by the appended claims rather than the foregoing description, which are therefore intended to fall within the scope of the claims.
