Description

Technical Field

[0001] The present invention relates to the technical field of elevator monitoring, and in particular to an elevator remote monitoring system and a monitoring method thereof. Background Art

[0002] As a kind of transportation equipment, elevators can be seen everywhere in daily work and life. Elevators are divided into two types according to their operation mode: with or without counterweight, and with counterweight. According to their control mode, they are divided into manual control type and automatic control type. In the daily safe operation of elevators, the repair and maintenance of elevators are very critical. However, elevators are only repaired after they fail, and maintenance also requires maintenance personnel to record and carry out, which increases the workload of maintenance personnel and is not conducive to the safe operation of elevators. Although there are monitoring systems or methods at present, their functions are relatively complex and their intelligence level is low, which is not conducive to the long-term safe operation of elevators.

[0003] Prior art 1, elevator intelligent monitoring camera, elevator monitoring system and elevator monitoring method CN201610019542.2, including: lens; video acquisition module and image processing module, collecting environmental images and state images captured by the lens, processing the collected environmental images and state images to form image information and send; video storage module, receiving and storing image information; position sensor; position processing module, collecting the position of the elevator detected by the position sensor, processing to form position information, and sending; illumination sensor, detecting the lighting conditions in the elevator and sending; speed sensor, collecting the running speed of the elevator and sending; central processing module, receiving image information, position information, lighting conditions and running speed in the elevator, analyzing to form and send fault information, or forming and sending fault information, emergency mode information and emergency mode instructions; emergency lighting module, audio processing module, turning on emergency lighting, speakers and microphones according to emergency mode instructions. Although remote monitoring across a large area is achieved, only alarms are realized when elevators fail, and prediction and maintenance reminders cannot be achieved.

[0004] Prior art 2, elevator monitoring method and elevator brake disc monitoring system CN201510856085.8, including: a beam generator emits a test beam, the test beam is irradiated obliquely on the liquid film surface, the part of the beam directly reflected by the liquid film surface is the first beam, the part of the beam that passes through the liquid film and is reflected by the brake disc surface and then passes through the liquid film is the second beam, the detector receives the first beam and the second beam to obtain the positional relationship between the first beam and the second beam, and calculates the thickness of the liquid film according to the positional relationship between the test beam, the first beam, and the second beam, and the refractive characteristics of the liquid film. When the thickness of the liquid film exceeds the preset warning value, the detector sends a stop signal or a standby signal to the elevator. Although the thickness of the liquid film on the surface of the elevator brake disc is monitored to ensure the safety of the elevator operation, the test beam does not damage the brake disc nor affect the normal operation of the brake disc, but only the monitoring of the elevator brake disc is realized, the monitoring object is single, and the monitoring result cannot fully reflect the operating status of the elevator.

[0005] Prior art three, elevator monitoring system CN202010466748.6, including an acquisition module, a communication module, a server and a user terminal; the communication module is connected to the acquisition module and the server respectively, and the server is connected to the user terminal; the acquisition module is used to collect the temperature signal of the elevator traction machine and the humidity signal of the elevator machine room environment, and process the temperature signal into a temperature value and the humidity signal into a humidity value, and the acquisition module is also used to send the temperature value and the humidity value to the communication module; the communication module is used to upload the temperature value and the humidity value to the server; the server is used to push the temperature warning information to the user terminal when the temperature value is greater than the temperature warning value, and is also used to push the humidity warning information to the user terminal when the humidity value is greater than the humidity warning value; the user terminal is used to display the temperature warning information and the humidity warning information. Although the detection of the humidity of the elevator machine room environment has been realized, the elevator equipment has safety hazards, but the operation status of the elevator equipment itself is not monitored, resulting in the elevator equipment still having safety hazards, and it is impossible to realize fault prediction and maintenance reminders.

[0006] At present, the existing technologies 1, 2 and 3 lack monitoring of the elevator equipment itself, which results in maintenance only when a fault occurs, which is time-consuming and labor-intensive and shortens the service life of the elevator; and the intelligence level of the monitoring is low, which is not conducive to shortening the operation time of repair and maintenance; in addition, the existing elevator monitoring system lacks monitoring of slender objects such as pet ropes, resulting in low safety of elevator operation; therefore, the present invention provides an elevator remote monitoring system and a monitoring method thereof, which realizes the monitoring of elevator equipment through the Internet of Things, predicts faults, and promptly notifies maintenance personnel to handle them, which not only prolongs the service life of the elevator, but also improves the safety of operation.
