Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0033] Such as figure 1 As shown, the elevator door operating state monitoring method based on TOF visual detection in this embodiment includes:

[0034] S1. TOF visual inspection: use TOF visual module to monitor the opening and closing action of the elevator door in real time and the continuous displacement data of the elevator door during the process of opening and closing the door;

[0035] S2. Acquisition of operation curve: obtain the operation curve of the elevator door in the process of opening and closing the door according to the continuous displacement data obtained by monitoring;

[0036] S3. Running state evaluation: Evaluate the running state of the elevator door according to the running curve in the process of opening and closing the door.

Abstract

The invention discloses an elevator door running state monitoring method and system based on TOF visual detection. The method comprises the steps that S1, a TOF visual module is used for monitoring door opening and closing actions of an elevator door and continuous displacement data of the elevator door in the door opening and closing processes in real time; S2, a running curve of the elevator door in the door opening and closing process is obtained according to the monitored continuous displacement data; and S3, the running state of the elevator door is evaluated according to the running curve in the door opening and closing process. The elevator door running state monitoring method can achieve monitoring of the elevator door running state without connecting a vertical elevator car door motor system, and has the advantages of being simple in implementation method, low in cost and complexity, high in precision, safe, reliable and the like.

Description

technical field [0001] The invention relates to the technical field of vertical elevators, in particular to a method and system for monitoring the operating state of elevator doors based on TOF visual detection. Background technique [0002] After a long period of use, the vertical elevator may have performance degradation or even malfunction, which will affect the safety of the elevator. Therefore, it is necessary to monitor the operating status of the elevator in real time. For the monitoring of the running status of vertical elevators, at present, sensors are usually installed to monitor whether there is a fault in the elevator. Typically, it is to monitor whether the elevator door is opened and closed normally, but the opening and closing of the elevator door is only a relatively easy to find fault. , while the health status of the elevator performance degradation is difficult to be detected by sensors. [0003] The elevator door of the vertical elevator usually does no...
