Embodiment Construction

[0018] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0019] Select photodiodes 3 of appropriate size according to the iron tower at a reasonable interval in the tower at a certain height from the top of the tower, such as being arranged on the ground figure 2 The squares shown make up the photodiode array. The detection and transfer device 4 is developed, and then the photodiode 3 and the detection and transfer device 4 are connected.

[0020] Rigidly fix the crosshair laser emitting module 2 on the top of the iron tower 1, and emit the crosshair laser 5 vertically downward to the photodiode 3.

[0021] When tower 1 swings, see image 3 , the crosshair laser 5 is shifted into the crosshair laser 6, and according to the signal fed back by the photodiode 3, the detection and transmission device 4 calculates the real-time offsets ΔX and ΔY.

[0022] When tower 1 swings and twists, see Figure 4 , the crosshair ...

Abstract

The invention relates to an iron tower inclination state detection method which comprises the following steps: distributing a circle of photodiodes on a plane with the distance of the certain height to the tower top according to the reasonable intervals to form a photodiode array, connecting the photodiode array with a detecting and transmission device, and utilizing the detecting and conveying device to receive detection signals of all the photodiodes; rigidly fixing a cross laser emission module to the top of the iron tower and vertically and downwards sending cross laser to the plane on which the photodiode array is arranged; when the iron tower swings, acquiring offset delta X and delta Y through the detecting and transmission device according to the detection signals of the photodiodearray; when the iron tower swings and twists, acquiring offset delta X and delta Y through the detecting and transmission device according to the detection signals of the photodiode array; acquiringoffset delta X and delta Y and a rotation angle theta.

Description

technical field [0001] The invention relates to a method for detecting the inclination state of an iron tower. Background technique [0002] Iron towers are widely used in the communication and power transmission industries. Because iron towers are affected by various uncertain factors such as wind and rain, earthquakes, extreme weather, wires, insulator string metals, etc., serious accidents such as accidental tilting or even collapse may occur during operation. The existing technologies mostly use off-the-shelf inclination sensors and wind speed sensors to form a measurement subsystem to monitor the tower status in real time, which has the problems of high cost, troublesome installation and maintenance, and is not convenient for large-scale application. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a measurement method for detecting the tilt state of the iron tower by using the crosshair laser emitting...
