Description
Technical Field
The invention belongs to the technical field of elevator management, and particularly relates to a remote centralized monitoring system applied to elevator operation and maintenance.
Background
In recent years, with rapid development of urbanization, the heights of residential buildings and office buildings are gradually increased, so that the number of elevators is also rapidly increased. However, the phenomena of shortage of elevator maintenance market personnel, fierce maintenance market competition and low price bid winning and maintenance generally exist, so that maintenance work is not in place, elevator faults are frequent, safety accidents caused by power failure, faults and the like cannot be timely processed, and industrial problems are increasingly highlighted.
At present, the maintenance problem of the elevator is mainly embodied in the following aspects:
(1) The maintenance is not in place. Due to the fact that industry competition is intense, and an effective supervision means for elevator maintenance is lacked by a management unit, the elevator fault rate is high.
(2) Failure alarm and rescue are not timely. When the elevator is trapped in a fault, people on duty go off duty or lack of technical means is a main reason for causing people trapping and untimely rescue.
(3) The function of no-sleepy people is one of main causes of elevator accident injury and loss expansion. The elevator breaks down, and the personnel of being trapped do not know the principle and the structure of elevator, and the mood is nervous, and blind self-rescue often makes dangerous action, if take off the door, tries to climb out etc. has caused a large amount of secondary injury occurences.
Therefore, how to effectively monitor the daily maintenance of the elevator and ensure the safe operation of the elevator, and the elevator can be reported in time after a fault (especially a person-related fault) occurs, becomes a difficult task to be placed in front of the property management department and the supervision department.
At present, there are many methods for remotely monitoring elevators at home and abroad, but from the perspective of property management units and related supervision units, the methods have the following defects:
(1) Many brands of elevators have own equipment systems for acquiring operation data and fault information codes, but the equipment systems are generally prone to being used as elevator maintenance data by maintenance units, and property management units are difficult to obtain related data. Because real-time information data of the property without the elevator fault exists, the responsibility for the fault is traced back, and the information is unequal.
(2) Because the standard communication protocol system does not exist in the current elevators of all brands, and manufacturers generally cannot provide communication protocols for other units due to technical barriers, operation and fault information can be acquired through the communication of the elevators. And the elevator brand of the property management enterprise is of various types, and the difficulty in realizing the operation and fault information unified monitoring of all managed elevators is high.
(3) Elevator management or supervision departments are also actively promoting intelligent elevator construction measures, such as implementing paperless elevator maintenance records. Generally, a two-dimensional code is posted at a position related to an elevator, and a mobile phone scans the code and uploads maintenance information when maintenance personnel perform maintenance on site. Some of the maintenance processes of the maintenance personnel are supervised by measures such as mobile phone positioning, real-time uploading of maintenance photos and the like, and the anti-cheating function is also realized. But also increases the workload of maintenance personnel and the inconvenience of field operation, and the completely adopted measure has certain defects and limitations for monitoring the maintenance work.

and/or the information acquisition analyzer is also used for defining the running state of the elevator as a top-flushing fault or a bottom-squatting fault when the photoelectric sensor or the first magnetic switch senses the magnet.
2. The remote centralized monitoring system applied to the operation and maintenance of the elevator according to claim 1,
the sensor also comprises infrared pyroelectric sensors arranged on the top of the elevator car and in the machine room control cabinet;
the information acquisition analyzer is also used for calculating the maintenance time of maintenance personnel on the top of the car or in the machine room control cabinet according to the sensing data of the infrared pyroelectric sensor.
3. The remote centralized monitoring system applied to elevator operation and maintenance according to claim 1,
the information acquisition analyzer is isolated from the sensor through a photoelectric coupler;
the information acquisition analyzer is also used for playing preset soothing voice through output equipment arranged in the elevator car when the running state of the elevator is trapped.
4. The remote centralized monitoring system applied to the operation and maintenance of the elevator according to claim 1,
the cloud server is specifically used for setting maintenance parameters;
and the information acquisition analyzer is used for downloading the maintenance parameters after logging in a cloud server.
5. The remote centralized monitoring system applied to the operation and maintenance of the elevator according to claim 1,
the cloud server is specifically used for supervising maintenance personnel according to the maintenance condition of the elevator, alarming when the maintenance duration of the maintenance personnel is detected not to meet a preset lower maintenance limit value, alarming when the maintenance time of the elevator is detected to be advanced or overdue, and alarming when the annual inspection time of the elevator is detected to be advanced or overdue.
6. The remote centralized monitoring system applied to the operation and maintenance of the elevator according to claim 5,
the cloud server is specifically used for pushing alarm information to related personnel and displaying data uploaded by the information acquisition analyzer in a form of a graph.
