Embodiment 1

[0046] Such as figure 1 As shown, the frequency conversion detection system for abnormal door opening and closing in this embodiment includes a door machine system 1 and an elevator control system 2, and the door machine system 1 communicates with the elevator control system 2 through an internal communication connection 3;

[0047] The door machine system 1 is used to output corresponding current through the frequency conversion controller 4, thereby controlling the door opening and closing action of the elevator hall door or car door; it specifically includes the frequency conversion controller 4, the door motor 5, the belt 6, the door leaf 7, Door guide rail 8, door sill 9 and door slider 10;

[0048] The door motor 5 is connected with the frequency conversion controller 4, and is used to receive the frequency conversion signal of the frequency conversion controller 4, and generate a torque through the current to control the opening and closing action of the elevator hall d...

Embodiment 2

[0057] Such as figure 2 As shown, this embodiment provides a frequency conversion detection method for abnormal door opening and closing, the method includes the following steps:

[0058] S1. The elevator control system controls the elevator to go up and down. After reaching the designated floor, it sends the door opening and closing command to the door operator system;

[0059] S2. The frequency conversion controller of the door machine system controls the door motor to open and close the door according to the door opening and closing instructions of the elevator control system;

[0060] S3. The elevator control system monitors the frequency conversion controller, reads the current value output by the frequency conversion controller, and outputs the current curve, monitors and compares the current curve with the normal curve, and detects when the current curve jumps abnormally or a certain value is abnormal. Whether there is a stall, if so, output a signal to the elevator c...

Abstract

The invention discloses a variable-frequency detecting system and a method for door opening and closing abnormity. The system comprises a door machine system and an elevator control system; the door machine system is communicated and connected with the elevator control system through an internal communication connecting wire; the door machine system is used for outputting corresponding current through a variable-frequency controller to control opening and closing actions of an elevator landing door or car door; the elevator control system is used for monitoring variable-frequency data of the variable-frequency controller to detect if abnormity in the door opening and closing process is generated; and if so, the abnormity type is judged, the fault code corresponding to the abnormity type is output, the floor information and the position information of the door machine system are stored, and the fault information is sent to development and debugging persons. The system needs no additional hardware to detect such information as the obstacle type and the operation state of the elevator door machine, saves the product cost, reduces the development and debugging costs, and can continuously maintain and upgrade the functions and algorithms in the later stage to satisfy the product development demands.

Description

technical field [0001] The invention relates to a frequency conversion detection system and method, in particular to a frequency conversion detection system and method for abnormal door opening and closing, and belongs to the technical field of elevator detection. Background technique [0002] In the context of the current era, the development of cities has driven the development of real estate, which has also led to the development of the elevator industry. Now more and more communities, real estate, villas and other places are gradually installing elevators. [0003] When the elevator is running, frequent door opening and closing operations are carried out every day, and each floor has a landing door. Incidents and other reasons will cause the elevator door to stop or be damaged. When such short-term or minor obstacles or damage accumulate, it is easy to develop into a mechanical failure or a bigger problem. For example, when elevator users take the elevator, they throw c...
