Problems solved by technology
If accidents such as cable towing and cable slack occur on the cable reel, it will cause the equipment to fail to operate normally, cause damage to the equipment and greatly reduce the efficiency of loading and transportation
[0003] The main reason for accidents such as cable towing and cable slack is that the reliability of the existing cable reversing limit device is not high, and it often fails to act in time when the cable is loose, resulting in cable towing accidents and cable damage
Moreover, after the cable towing accident occurs, the control system cannot detect its fault state, and cannot perform warning and maintenance at the first time, which has potential safety hazards

Embodiment approach
[0025] According to one embodiment of the present invention, assuming that the traveling mechanism 40 of the cable reel starts to move from the first area to the reversing point (that is, the traveling mechanism 40 of the cable reel is on the left side of the reversing point) and starts to wind the cable. The first detection device 100 on the running frame of the cable reel's traveling mechanism can detect the position of the cable reel's traveling mechanism 40 and send a signal of the traveling mechanism's position to the receiver 300 . Wherein, the first detection device 100 may be various appropriate detection devices such as inductive switches (such as holding magnetic switches, etc.), encoders (such as multi-turn encoders, etc.), or DGPS, etc., and the present invention does not Not limited.
[0026] According to an embodiment of the present invention, the first detection device 100 may be a magnetic switch, which can change state (for example, closed state and open state...

The invention discloses a method and a system for controlling a cable drum. The system comprises a first detection device, a second detection device, a receiver and a controller, wherein the first detection device is installed on a traveling support of a traveling mechanism of the cable drum and used for detecting the position of the traveling mechanism of the cable drum; the second detection device is mounted on an outer support of a guide frame of the cable drum and used for detecting the state of the guide frame of the cable drum; the receiver is connected with the first detection device and the second detection device and used for receiving position signals of the traveling mechanism of the first detection device and state signals of the guide frame of the second detection device; and the controller is connected with the receiver and used for determining whether the cable drum works normally according to position signals of the traveling mechanism and state signals of the guide frame, and controlling the cable drum to execute cable winding and laying operations under the condition that the cable drum is determined to work normally. According to the method and the system, accidents such as cable towing and cable loosening can be avoided, and loading and transportation efficiencies are improved.
Description
technical field [0001] The present invention relates to a method and a system for controlling a cable reel, in particular to a method and a system for controlling a cable reel. Background technique [0002] In the prior art, a cable reel (also called a cable reel) is an important device to ensure the operation of large-scale loading and transportation equipment (eg, stacker, reclaimer, ship loader, etc.). If accidents such as cable towing and cable slack occur on the cable reel, it will cause the equipment to fail to operate normally, cause damage to the equipment and greatly reduce the efficiency of loading and transportation. [0003] The main reason for accidents such as cable towing and cable slack is that the reliability of the existing cable reversing limiting device is not high, and it often cannot act in time when the cable is loose, resulting in cable towing accidents and cable damage. Moreover, after the cable towing accident occurs, the control system cannot dete...
