Embodiment 1
[0112] Figure 4 It is a schematic diagram of a mine multi-rope friction hoist steel wire rope online monitoring system in an embodiment of the present invention, as Figure 4 As shown, the mine multi-rope friction hoist wire rope online monitoring system includes a laser scanner 15, an image acquisition device, a synchronous acquisition device 5, a power box 6, a signal transmitter 7, a signal receiver 8, a monitoring display 11 and an industrial computer 13.
[0113] Here, the mine multi-rope friction hoist steel wire rope on-line monitoring system is used to monitor the steel wire rope 16 of the hoist wire rope. The mine 18 moves up and down for transporting goods or miners; in order not to affect the operation of the multi-rope friction hoist in the mine, the online monitoring system will be far away from the mine 18 by a preset distance, and the farthest can reach more than 100 meters.
[0114] The laser scanner 15 can help the image processing device to quickly determi...

[0140] Figure 9 It is a schematic flow chart of the mine multi-rope friction hoist steel wire rope online monitoring method in the second embodiment of the present invention, as Figure 9 As shown, the displacement monitoring method of the mine hoisting equipment includes the following steps:
[0141] Step 500: camera calibration and correction;
[0142] Before acquiring images, the left and right cameras are calibrated and corrected to eliminate the image distortion caused by the camera itself.
[0143] Step 501: static marker acquisition;
[0144] Take pictures of static markers when the wire rope is not running to obtain a ruler.
[0145] Step 502: laser scanning;
[0146] scanning the profile of the steel wire rope of the hoist to obtain profile data of the steel wire rope of the hoist.
[0147] Step 503: video stream shooting and transmission;
[0148] After the monitoring starts, the running video of the steel wire rope is taken and transmitted to the industrial c...
