Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] like figure 1 As shown, the elevator health detection device of the present invention includes a vibration detection component 1 , a power measurement component 2 , a load measurement component 3 , a GPRS / 4G gateway 4 , a central server 5 and a data processing module 6 .

[0040]The power measurement part 2, on the basis of conventional power measurement, increases wireless WIFI or CAN bus interface and GPRS / 4G gateway communication.

[0041] The load measuring component 3 can adopt the existing load measuring technology and data of the elevator, and the GPRS / 4G gateway 4 obtains the data from the elevator controller; or when the elevator is remodeled, a load measuring sensor is installed at the bottom of the car to obtain the load data.

[0042] The central server 5 communicates with the GPRS / 4G gateway 4 of the remote elevator to obtain and store el...

Abstract

The invention discloses an elevator health status detection device and method; the device includes a vibration detection component, a power measurement component, a load measurement component, a GPRS / 4G gateway, a central server, a data processing module and the like. The invention provides key data such as vibration parameters, balance coefficients, and transmission loss coefficients of elevator operation, as well as data such as conventional fault alarms, and comprehensively evaluates the health status of the elevator. The health data provided by the device of the present invention can help maintenance personnel prescribe the right medicine to eliminate potential safety hazards; it can also assist elevator manufacturers to analyze elevator quality and improve manufacturing and design levels.

Description

technical field [0001] The invention relates to the field of mechatronics, in particular to a method for detecting the health status of an elevator. Background technique [0002] The elevator is a complex electromechanical system. Due to reasons such as design and manufacture, installation and commissioning, operating loss and wear, etc., it will cause system vibration, unbalance between the car and the counterweight, excessive power consumption of the motor, and electronic, electrical, etc. own failure etc. General appearance damage, as well as alarms and faults of the controller, are easy for maintenance personnel to identify and solve. However, some internal and essential changes in the operation of the elevator have not yet reached the level of failure, and often do not attract the attention of maintenance personnel and manufacturers. At the same time, there is no good way to reflect these changes. Once the quantitative change reaches qualitative change and a failure oc...
