DETAILED DESCRIPTION

[0056] The present invention will be further described below in conjunction with the accompanying drawings.

[0057] Embodiment 1

[0058] like Figure 1 As shown, this embodiment provides a cable conveying method, comprising the following steps:

[0059] S1. Determine the transmission route;

[0060] S2, determine the direction change node according to the transmission line;

[0061] S3, setting a cable conveying device on the direction change node;

[0062] S4, determining a change in cable length and a change in cable bending radius during cable transportation according to the three-dimensional terrain;

[0063] S5. Adjust the position of the cable conveying device according to the change in cable length and cable bending radius.

[0064] The cables are transported through the cable conveying device according to the cable conveying route. At the same time, the state of the cable conveying device is adjusted according to the change in cable length and cable bending radius of the cable conveying device at different angles, so as to better transport each cable in real time and adapt to complex and diverse geographical environments.

[0065] Determining the transmission route in S1 comprises the following steps:

[0066] S11, scanning the three-dimensional terrain where the cables need to be transported;

[0067] S12, obtaining direction change nodes that require cable reversal according to the three-dimensional terrain, and arranging them in sequence according to the order of the direction change nodes set by the cable conveying device;

[0068] S13, measuring the lengths between two adjacent direction change nodes in sequence to obtain all segment data;

[0069] S14. Establish a cable transmission line based on all the section data.

[0070] By scanning the three-dimensional terrain of the line, we can more clearly determine the equipment required in the cable transportation process, and adjust the equipment in the cable transportation process according to the data, making the cable transportation smoother and more convenient.

[0071] Preferably, step S2 comprises:

[0072] S21. Obtaining specifications of the transport cable;

[0073] S22. Determine the length change of the cable according to the specification of the transport cable.

[0074] According to the specifications of the cable, the length change of the cable itself is determined, and the adjustment of the conveying equipment during the cable conveying process is determined by the length change of the cable itself.

[0075] Preferably, the step S3 comprises:

[0076] S31, determining the angle and height that each cable conveying device needs to change according to the three-dimensional terrain;

[0077] S32, obtaining the initial state of each cable conveying device;

[0078] S33, obtaining a completion state of the cable reversal according to the angle and height that the cable conveying device needs to change;

[0079] S34. Setting a plurality of cable conveying devices corresponding to the conveying lines according to the initial state and the completed state of the cable conveying device.

[0080] According to the change in cable length and cable bending radius during cable transportation, the specific state of the cable transportation device in actual work is determined, and a cable transportation device corresponding to the transportation line is set to make the cable transportation process smoother.

[0081] Furthermore, the step S31 includes:

[0082] S311, obtaining the position of each cable conveying device in the three-dimensional terrain;

[0083] S312, determining the angle of the cable conveying device in different conveying directions according to the position of the cable conveying device;

[0084] S313, determining the angle and height that each cable conveying device needs to change according to the angles of the cable conveying device in different conveying directions.

[0085] After determining the operating position of the cable conveying device in the three-dimensional terrain, the direction reversing process of the cable conveying device at various angles is further determined, so that the conversion between various direction change nodes of the cable conveying device is smoother.

[0086] Preferably, the step S4 comprises:

[0087] S41, obtaining a cable length change between two adjacent direction transformation nodes in the three-dimensional terrain, and determining whether it is within an allowable range. If it is within the allowable range, proceeding to subsequent steps; if it is not within the allowable range, recalculating the node position or adding a transformation node between two adjacent direction transformation nodes that are not within the allowable range;

[0088] S42, obtaining the cable bending radius variation between adjacent direction change nodes in the three-dimensional terrain, and determining whether it is within the permitted range. If it is within the permitted range, proceeding to the subsequent steps; if it is not within the permitted range, recalculating the node position or adding a change node between two adjacent direction change nodes that are not within the permitted range;

[0089] S43, calculating the angle and height that the cable needs to be adjusted between two direction transformation nodes according to the cable length change and the cable bending radius change;

[0090] S44, setting the placement angle of each cable conveying device and the height of the cable conveying device to raise or lower the cable according to the angle and height that need to be adjusted between the two direction conversion nodes of the cable.

[0091] According to the change of the cable between the two direction transformation nodes, the position and angle of the cable conveying device are obtained through calculation. At the same time, transformation nodes are added between two adjacent direction transformation nodes where the cable length exceeds the allowable value to improve the cable conveying efficiency in the three-dimensional environment.

[0092] Furthermore, the step S41 includes:

[0093] S411, determining whether the three-dimensional terrain where the transmission line is located is flat;

[0094] S412, when the three-dimensional terrain where the transmission line is located is flat, no processing is performed; when the three-dimensional terrain where the transmission line is located is uneven, the length change of the cable during the transmission process is determined according to the three-dimensional terrain;

[0095] S413, setting a threshold value for the cable length change during the conveying process, stopping the conveying and alerting the operator when the threshold value is exceeded.

[0096] By analyzing the status when the cable length exceeds the threshold, the cable transportation can be stopped in time when the cable length change exceeds the threshold, thereby improving the safety of the cable transportation process.

[0097] Furthermore, when the cable length changes beyond a threshold during the transportation process, recalculation can be performed. If multiple calculations still cannot resolve the problem of the cable length changing beyond the threshold, the transportation step is stopped and an alarm is alerted to the operator. At the same time, the display device or other connected smart device points out to the operator that the threshold has been exceeded, and lists the efforts made in the automatic calculation, saving the operator's solution time.

[0098] Preferably, the cable conveying method further comprises:

[0099] S6, real-time monitoring of key parameters during cable transportation;

[0100] The key parameters include tension, speed and temperature.

[0101] Preferably, the method further comprises:

[0102] S7, dynamically adjusting the operating parameters of the cable conveying device according to the monitoring data;

[0103] The operating parameters include the angle of the cable conveying device and the height at which the cable conveying direction is changed.

[0104] Furthermore, the step S6 also includes: setting a plurality of monitoring points on the transmission line, setting a monitoring system at each monitoring point, and setting detection items (including but not limited to key parameters and operating parameters) on the monitoring system.

[0105] The key parameters in the cable transportation process are set as detection items. The actual status of the cable transportation process is detected through the detection items, so as to timely judge the status of the cable during the transportation process.

[0106] The step S6 comprises:

[0107] S61, acquiring monitoring data during the cable conveying process, wherein the monitoring data includes cable tension, cable temperature, and cable conveying speed;

[0108] S62. Dynamically adjust the angle and height of the cable conveying device according to the cable tension, cable temperature, and cable conveying speed.

[0109] By dynamically adjusting the angle and height of the cable conveying device, the state of the cable conveying process is made more stable. Specifically, multiple tension detectors, temperature sensors and speed detectors are set in the cable conveying line to detect cable data. Various detection technologies are existing technologies and will not be described in detail here.

[0110] The step S62 comprises:

[0111] S621, when conveying the cable within a preset cable tension setting range, adjusting the conveying height of the cable conveying device to achieve an optimal cable tension;

[0112] S622. When the preset cable tension is outside the setting range, an alarm is triggered and the cable conveying is stopped.

[0113] Step S62 can eliminate the potential risk that the cable cannot be transported when the cable is outside the preset cable tension setting range or the cable is damaged.

[0114] In step S622, after the alarm is given, the optimal cable tension is achieved by adjusting the conveying height to lower or increase the angle of the cable conveying device. If the optimal cable tension cannot be achieved, the cable conveying needs to be stopped and a maintenance request is issued to the maintenance personnel.

[0115] Similarly, when the cable temperature and cable conveying speed are abnormal, an alarm is also issued. The abnormal state is eliminated by adjusting the conveying height to lower or increase the angle of the cable conveying device. If the abnormal state cannot be eliminated, the cable conveying is stopped and a maintenance request is issued to the maintenance personnel.
