Problems solved by technology

[0004] The existing safety belt can only ensure the correct connection and use of the safety rope through the standardized operation of management and use. In the actual work process, the safety belt user often has human negligence, operational errors, etc., resulting in the failure of the safety rope in the safety belt. Hook is in an unsafe state

Embodiment 1

[0043] A safety rope hooking state recognition method based on distance and attitude, such as figure 1 , the reference point 400 and the anchor point 500 are correspondingly provided at the two ends close to the safety rope 100, when the anchor point 500 remains stationary relative to the reference point 400, the distance between the anchor point 500 and the reference point 400, and the anchor When the fixed point 500 moves up and down, the distance between the anchor point 500 and the reference point 400 is used to identify the hooking state of the safety rope 100 according to the two distances.

[0044] It should be noted that the stationary state of the present invention means that the anchor point 500 remains relatively stationary relative to the reference point 400 for a period of time. This time interval can be 10s, 60s, 120s, 600s, etc. The specific time interval can be determined according to the actual situation. adjust.

[0045] The position of the anchor point 500 ...

Embodiment 2

[0054] A safety rope attachment state recognition method based on distance and posture, other features are the same as in Embodiment 1, the difference is that: the reference point 400 of the present invention is provided with a first distance detection module, and the anchor point 500 is provided with a second distance A detection module and a movement detection module for detecting whether the anchor point 500 moves up and down. The first distance detection module is wirelessly connected to the second distance detection module. Both the first distance detection module and the second distance detection module are UWB modules; the movement detection module is a gyroscope.

[0055] It should be noted that the distance detection method through the UWB module is a common detection method, and its detection method is not the focus of the present invention, and those skilled in the art should know its principle and model selection, and will not repeat them here. And the method of m...

Embodiment 3

[0058] A safety rope, which adopts the method for identifying the hooking state of the safety rope based on distance and posture as in Embodiment 1 or 2 to identify the hooking state.

[0059] The safety rope can identify the position of the safety rope 100 in the static state through the distance between the anchor point 500 and the reference point 400 in the static state, and the distance between the anchor point 500 and the reference point 400 during the movement process. In the hooked state, the operating safety of the operators can be improved, and the intelligence of the safety rope 100 can be realized.

Abstract

A safety rope hooking state identification method based on distance and posture comprises the following steps: correspondingly arranging a reference point and an anchoring point at two tail ends close to a safety rope, detecting the distance between the anchoring point and the reference point when the anchoring point is kept in a static state relative to the reference point, and detecting the distance between the anchoring point and the reference point when the anchoring point moves up and down. According to the distance between the anchoring point and the reference point, the hooking state of the safety rope in the static state is recognized according to the two distances. Through the relation between the distance of the anchor point relative to the reference point in the static state and the distance between the anchor point and the reference point in the moving process, the hooking state of the safety rope in the static state can be recognized, so that the operation safety of operators can be improved, and the intelligence of the safety rope is realized.

Description

technical field [0001] The invention relates to the technical field of safety ropes, in particular to a method for identifying the hooking state of a safety rope based on distance and posture and a safety rope using the identification method. Background technique [0002] When working at heights, the primary task is to ensure the safety of the workers. Among them, the safety rope is one of the most commonly used protection methods for high-altitude operations. It is necessary to fix one end of the safety rope with a hook, and the hook is hooked to a fixed point, and the other end of the safety rope is connected to the whole body belt of the operator. It can effectively prevent construction workers from falling from high altitude. [0003] The hooking status of the safety rope is divided into low hanging high use, flat hanging flat use and high hanging low use. The state of low-hanging and high-use or horizontal-hanging-flat-use is a non-safe use state, while high-hanging a...
