Fault diagnosis and safety pre-warning oriented elevator monitoring system and method

Abstract

The invention discloses a fault diagnosis and safety pre-warning oriented elevator monitoring system and method. A cloud-side processing module is used for receiving data of all machine room board modules and camera modules in multiple elevator cars and achieving the computation and storage functions. The machine room board modules control data of the multiple elevator cars, achieve the computation and temporary storage functions and transmit computation results to the cloud-side module. Elevator car ceiling board modules collect data of the corresponding single elevator cars, transmit the data to elevator car ceilings in an I2C mode to be processed and transmit processing results to the machine room board modules. Elevator car door board modules are used for collecting data of barometer sensors and three-axis acceleration sensors mounted nearby elevator car doors, conducts filtering, integration and vibration analysis on the data and transmit processing results to the corresponding elevator car ceiling board modules for being processed. The fault diagnosis and safety pre-warning oriented elevator monitoring system achieves the real-time monitoring analysis effect through layer-by-layer grading and function decoupling of all the modules and meanwhile improves the elevator running state monitoring and fault pre-warning accuracy.

Description

technical field [0001] The invention relates to an elevator running state monitoring technology, in particular to an elevator monitoring system and method for fault diagnosis and safety early warning. Background technique [0002] With the widespread application of elevators in buildings, accidents caused by hidden safety hazards have gradually increased. In recent years, the safe operation of elevators has received extensive attention. Although the elevator products put into operation have met the national standards and their safety is guaranteed to a certain extent, in order to ensure the safe operation of elevators to a greater extent and reduce the occurrence of accidents, the elevator maintenance industry and some property companies have gradually begun to adopt the original The operation status monitoring system outside the elevator system provides third-party monitoring information. When the main system fails unexpectedly, the monitoring system can still obtain enough...

Problems solved by technology

[0003] At present, the system used for elevator monitoring is generally only used for the detection of the running status of the elevator. Although the elevator running speed, acceleration, height and position can be obtained, but in comparison, the acquired data information is not fully utilized for data processing. Excavation and processing cannot obtain all the status of the elevator, nor can it detect elevator faults, let alone evaluate the health status of the elevator, so as to judge whether the elevator may be faulty in advance, and to achieve early detection and maintenance

[0004] On the other hand, the existing elevator quality inspection methods are usually regular inspections, and the elevator quality inspection instrument used is usually a toolbox, which is placed in the elevator car during regular inspections to perform acceleration vibration analysis and noise inspection, etc. In this way, when the elevator fails, it cannot be detected and dealt with in time, and the health status of the elevator cannot be monitored in real time

Because of this method, its instruments and equipment are separated from the elevator monitoring system, so the operating status of the elevator cannot be obtained
