Example Embodiment

[0017] Examples:

[0018] When the elevator is in use, the signal acquisition device 2 uses the monitoring chip 3 connected to the system to comprehensively monitor the drive circuit and control switches in the elevator. Synchronously, the signal acquisition device 2 will monitor the data obtained by visual operation. The form, directly displayed on the monitoring terminal, the operator can set the control parameters in the system according to actual use requirements, and the signal acquisition device 2 will control the elevator according to the control instructions issued by the operator.

[0019] When the monitoring chip 3 detects an abnormal signal in the circuit, the monitoring chip 3 sends the detected signal to the signal acquisition device 2, and the monitoring module corresponding to the monitoring chip 3 reports the abnormal signal to the automatic safety control module 21, which automatically The safety control module 21 analyzes the obtained abnormal signals, and at the ...

Abstract

The invention discloses a safety loop signal collecting system which comprises an elevator control panel. The safety loop signal collecting system is characterized by being formed by a signal collecting device, monitoring chips and a monitoring terminal. The multiple monitoring chips are arranged at the lower end of the signal collecting device and monitor all control loops and all control switches in an elevator, the monitoring terminal is connected with the signal collecting device, and the signal collecting device is connected with the elevator control panel. According to the safety loop signal collecting system, the structural mode that all-directional monitoring on the control loops and the control switches in the elevator is carried out through independent modularization, operating states of the elevator are adjusted according to monitoring data, and meanwhile the monitored operating states are visibly reflected to the monitoring terminal is adopted, so that the functions of intelligent monitoring and safe shutdown of the elevator are achieved, the use safety performance of the elevator is guaranteed, the service life of the elevator is prolonged, and safety accidents are avoided.

Description

technical field [0001] The invention relates to an elevator control system, in particular to a safety loop signal acquisition system. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, elevators are more and more widely used in modern office buildings or high-rise residential buildings. Elevators not only solve the problem of people climbing up and down high-rise buildings, but also effectively reduce the problem of prolonged travel time due to high floors. Elevators have become an indispensable tool in human life in modern cities. [0003] As elevators are becoming more and more popular, people are paying more and more attention to the safety of elevators, and information about elevator safety accidents can be seen from time to time in the media. Most of the elevator accidents are caused by the aging failure of elevator components or the abnormality of the control circuit. Although sometimes ...
