Embodiment Construction

[0015] see figure 1 , the intelligent elevator braking control system of the present invention includes a controller 10 , a detection component 20 and a monitoring device 30 . The controller 10 is signal-connected with the detection component 20, and the detection component 20 is used to detect parameters such as the stress of the elevator host a close to the brake pad, the stroke of the brake, the current and the temperature, and transmit the detection data to the controller for further processing. Calculation. The monitoring device 30 is signal-connected with the controller 10, and the monitoring device 30 is used for notifying the maintenance and maintenance of the elevator.

[0016] Specifically, the detection component 20 of this embodiment includes a stroke sensor, a stress sensor, a brake current sensor and a temperature sensor.

[0017] The travel sensor includes a left travel sensor 21 and a right travel sensor 22, the left travel sensor 21 and the right travel sens...

Abstract

The invention relates to an intelligent elevator brake control system. The intelligent elevator brake control system comprises a controller and a detection assembly. The controller is in signal connection with the detection assembly. The detection assembly comprises travel sensors and stress sensors. The travel sensors comprise the left travel sensor and the right travel sensor. The left travel sensor and the right travel sensor are arranged on a left brake body and a right brake body correspondingly and are both in signal connection with the controller. The stress sensors comprise the left stress sensor and the right stress sensor. The left stress sensor and the right stress sensor are arranged on the two sides of the position, in contact with a left brake pad and a right brake pad, on anelevator host correspondingly and are both in signal connection with the controller. The intelligent elevator brake control system is sensitive in detection, capable of achieving automatic analysis and judgment and high in response speed.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an intelligent elevator braking control system. Background technique [0002] The elevator braking system is one of the core components of the elevator, which involves the core components of the elevator and personal safety. The normal start and stop of the elevator and the safe stop in emergency situations require the cooperation of the braking system. The elevator brake system is generally composed of the main machine brake and the brake drive control circuit. The brake is used for the braking of the main engine of the elevator, and the brake drive control circuit provides the power supply of the brake to control the pull-in and release of the brake. [0003] At present, the control of the brake drive control loop for the brake is only the control of power on and power off. For the detection of the elevator brake, only the stroke of the brake is detected by the travel switc...
