Embodiment Construction

[0037] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0038] Such as figure 1 As shown, a monitoring device for automatic supervision of elevator maintenance according to the present invention includes an elevator controller 1, a processing unit 2, an inspection switch 3 and a safety circuit 4, the elevator controller 1 is a control component of an elevator, and the safety Loop 4 is a circuit loop for keeping the elevator suspended during elevator maintenance and overhaul. The IO port of the elevator controller 1 is connected to the safety circuit 4, and the inspection switch 3 is connected in series to the connection line between the IO port of the elevator controller 1 and the safety circuit 4. The state of the elevator is controlled through the inspection switch 3, that is, the elevat...

Abstract

The invention relates to a monitoring device and method for automatically monitoring elevator maintenance and overcomes the defect that elevator maintenance is difficult to monitor automatically as compared with the prior art. The monitoring device comprises a current transformer. The connecting circuit of the IO port of an elevator controller and a safety loop penetrates the annular magnetic core of the current transformer. The current transformer is located between the elevator controller and a maintenance switch. The signal output end of the current transformer is connected with the signal input end of a processing unit. The monitoring device has the advantages that the device does not contact with an elevator control system during monitoring, the state of the maintenance switch is indirectly detected so as to determine whether an elevator is maintained or not, influence on the original elevator control system is avoided, and convenience and reliability in implementation are achieved.

Description

technical field [0001] The invention relates to the technical field of elevator maintenance, in particular to a monitoring device and a monitoring method for automatic supervision of elevator maintenance. Background technique [0002] With the implementation of the national urbanization strategy and the shortage of urban land resources, the number of high-rise buildings is increasing, and people rely more and more on elevators. Elevators have become one of the indispensable public transportation tools in modern social life. Security has become the focus of attention. The quality of daily elevator maintenance is directly related to the safety of elevator operation. Due to the lack of effective maintenance supervision methods, maintenance is not timely, maintenance goes through the motions, and the phenomenon of inadequate maintenance is not uncommon. This has become one of the important factors that cause elevator failures and accidents. . [0003] The technical solution ...
