Description

Technical Field

[0001] The present invention relates to the technical field of elevator traction machine control, and specifically to an elevator traction machine control system capable of monitoring braking and its control method. Background Art

[0002] With the progress of technology, the building height of people has been gradually increased. The increase in building height makes it necessary for people on the lower floors to move to the upper floors through stairs, thus making the overall movement process time-consuming and laborious. In order to facilitate the use of users, people have designed a vertical moving device for carrying people, enabling users to move to the required height, which is later called an elevator. An important device required during the use of an elevator is a traction machine, which controls the height of the elevator by pulling force. When users use the traction machine, they need to use a control system.

[0003] However, the existing control system only controls the elevator traction machine during use and cannot monitor the elevator traction machine during use, making it impossible to quickly understand the situation in case of an accident. Therefore, it does not meet the existing requirements. For this reason, we have proposed an elevator traction machine control system capable of monitoring braking and its control method. Summary of the Invention

[0017] An elevator traction machine control system capable of monitoring braking and its control method include the following steps:

[0018] Step 1: The call signal gives a signal to the inverter through the signal controller. The inverter will control the rotation speed of the elevator traction machine, so that the elevator can move to the floor height where the call signal is issued.

[0021] Step 4: During the use of the elevator traction machine, a timing element and a noise detection element will time and start a camera element by noise respectively. The camera element will send a signal to a camera, and the video captured by the camera will be uploaded through a video recording upload element and stored inside a video recording storage element.

While controlling the traction machine, monitor the weight and times borne by the traction machine, monitor the use of the traction machine, and perform maintenance in a timely manner, improving the safety factor during use and preventing accidents.

[0025] 2.
