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

[0002] An elevator is an electromechanical device that is driven by power and uses a box running along a rigid guide rail or steps running along a fixed line to lift or transport people and goods in parallel. It includes passenger (cargo) elevators, escalators, moving walkways, etc., and is used to provide services on specific floors. In order to ensure the safety of elevator operation, detection devices are usually installed for the elevator to monitor the elevator's operating index.

[0003] However, elevators are usually installed in vertical corridors on higher floors. The elevator's monitoring device is partly installed inside the elevator and partly installed in the main engine room at the top of the corridor to monitor the elevator's traction machine, control cabinet, etc. However, there is a lot of dust inside the corridor. Long-term use in dust will affect the accurate use of the monitoring device. Dust sticking to the heat dissipation slot of the monitoring device will cause the internal temperature to rise, leading to damage to the internal components of the monitoring device. Therefore, manual maintenance and dust cleaning are required on a regular basis, which increases the manual workload. Summary of the invention

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The elevator monitoring device and monitoring method use a driving motor to drive the mounting frame to rotate, so that the traction rope drives the cleaner to clean the heat dissipation dustproof plate, cleans the dust on the heat dissipation dustproof plate, avoids dust clogging the heat dissipation dustproof plate, and makes the heat dissipation effect inside the control box worse, reduces manual dust cleaning work, and improves the work efficiency during elevator maintenance.

[0016] 2. The elevator monitoring device and monitoring method drive the outer tube to rotate by rotating teeth, thereby allowing the rotating cylinder to rotate between the outer tube and the dust removal plate. During the rotation, the rotating cylinder contacts one end of the swing plate, allowing the swing plate to swing along the movable rod.

In the process of cleaning dust, it is convenient to vibrate and remove dust adhered to the heat dissipation dustproof plate. At the same time, the vibration will make it difficult for dust to adhere to the dust removal plate, thereby reducing the cleaning time and being easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

The width of the rotating brush 632 is consistent with the width of the heat dissipation dustproof plate 603, thereby ensuring that the dust on the heat dissipation dustproof plate 603 is completely cleaned.

[0024] The guide 606 includes a support frame 620, a roller 621, a limit rod 622 and an arc-shaped guide block 623.

[0025] The rotating brush 632 includes an outer tube 640, a dust removal plate 641, an inner tube 642, a rotating cylinder 643, a movable rod 644, a swing plate 645 and a vibration plate 646.

One end of the swing plate 645 collides with the vibration plate 646 during the swinging process, thereby driving the vibration plate 646 to vibrate and form a low-frequency vibration. In the process of cleaning dust, it is convenient to vibrate and remove dust adhered to the heat dissipation dustproof plate 603. At the same time, the vibration will make it difficult for dust to adhere to the dust removal plate 641, thereby reducing the cleaning time and making it easy to use. There are six dust removal plates 641, which are evenly distributed on the outside of the outer tube 640. Effective dust cleaning can be ensured by the six dust removal plates 641.

[0026] The controller 609 includes a sensor, an overspeed monitor, a vibration monitor, and a power monitor, which are sequentially distributed on the controller 609. The elevator operation process is monitored through the sensor, the overspeed monitor, the vibration monitor, and the power monitor.

[0027] The monitoring method of the elevator monitoring device is as follows: the lifting host 2 is started, the rope 3 is driven to make the elevator car 4 move up and down, and then the detector 6 monitors the lifting host 2 and the elevator car 4; the controller 609 inside the detector 6 operates, and the sensor, overspeed monitor, vibration monitor, and power monitor start to work; the overspeed monitor sets a speed threshold for the speed of the rope 3, collects the speed of the elevator in real time through the overspeed monitor, uses an analog sensor to obtain an analog signal, and converts it into a digital signal through an analog-to-digital converter; the vibration monitor sets a vibration threshold, collects the acceleration of the elevator in real time, and smoothes the collected acceleration data. In order to weaken high-frequency noise and vibration interference, the acceleration data is monitored in real time by comparing with the threshold value to determine whether there is abnormal vibration; the power monitor collects the current and voltage of the elevator in real time, calculates the real-time power consumption of the elevator based on the collected current and voltage data, and monitors the power consumption of the elevator in real time by comparing with the set power range; the overspeed monitor, vibration monitor, and power monitor collect data and transmit the collected data to the sensor, and then the controller 609 starts the monitoring algorithm to monitor and judge the status of the elevator, and transmits it back to the elevator control center through the sensor to inspect and process the elevator.

[0028] When in use, the lifting host 2 starts to operate, the elevator car 4 starts to lift, the detector 6 starts to monitor the lifting host 2 and the elevator car 4, the internal devices work and generate heat, which is dissipated through the heat dissipation and dustproof plate 603. At the same time, the heat dissipation and dustproof plate 603 prevents dust from entering the control box 601. The dust adheres to the heat dissipation and dustproof plate 603. Then the driving motor 604 is started to drive the traction wheel 605 to work, to pull the traction rope 607, and let the cleaner 608 reciprocate up and down in the mounting frame 602 to process the dust. The rotating brush 632 in the cleaner 608 plays a dust cleaning role. The rotating cylinder 643 inside the rotating brush 632 rotates between the outer tube 640 and the inner tube 642, driving the swing plate 645 to swing, forming an impact on the vibration plate 646, causing the vibration plate 646 to form a low-frequency vibration. The low-frequency vibration cooperates with the rotation of the dust removal plate 641 to achieve a better cleaning effect on the dust on the heat dissipation and dustproof plate 603.
