Background
With the rapid increase of the power demand, the power industry in China has also developed greatly, and the contradiction between the transmission capacity and the line tension tends to be relaxed with the occurrence of split conductors. The split conductor has important significance for saving energy, reducing consumption, improving the conveying capacity of unit line corridors and constructing a 'resource-saving and environment-friendly' power grid. The split conductor has the advantages of small line loss, large transmission power and few line loops, so that the number of corridors of the power transmission line is reduced, and the required land resources are reasonably saved.
However, a tension pay-off method is required to be adopted in the split conductor spreading construction, once a large height difference, a large corner, a large span and important cross spanning exist in the tension pay-off construction process, a plurality of key control points need to be strictly controlled, and otherwise accidents such as conductor groove jumping, loosening and falling of connecting parts and the like easily occur.

The paying-off tackle danger early warning method is applied to a data processing center, the data processing center is in communication connection with a paying-off tackle, the paying-off tackle is provided with a data transmission center and a plurality of sensors which are in cable communication connection, and the method comprises the following steps:
referring to fig. 3, fig. 3 shows a schematic structural view of a payoff tackle according to an embodiment of the present invention. The sensors can be strain sensors and double-shaft inclination angle sensors which are arranged on cross beams on two sides of the paying-off tackle, and the data transmission center can be a data acquisition and transmission module; the power supply of the sensor and the data transmission center is provided by a high-capacity lithium battery arranged on the pulley beam; the outside of the lithium battery is protected by a high-strength composite material, wherein the high-strength composite material can be metal, so that collision and rain can be prevented; in order to facilitate wiring adjustment, the paying-off tackle is further provided with a tackle door.
In this embodiment of the present invention, the predetermined transmission rate includes a low frequency transmission rate and a high frequency transmission rate, and the step 201 may include the following cases:
when the variation of the motion information is greater than or equal to a first preset threshold value, or when the numerical value of the motion information is greater than or equal to a second preset threshold value, receiving the motion information sent by the data transmission center at a high-frequency transmission rate;
in the embodiment of the present invention, in order to balance transmission power consumption and transmission effectiveness, a first preset threshold and a second preset threshold may be set as a start threshold for frequency conversion transmission, where the first preset threshold may be set to have a variation exceeding 20% or 40% of current motion information, and the second preset threshold may be set to have a value of the motion information being about 80% of a limit bearing capacity of the payoff tackle, or may be set by a worker according to an actual situation.
In a specific implementation, when the variation of the motion information is greater than or equal to a first preset threshold value during data transmission, it is indicated that the motion state of the pay-off tackle changes violently at the moment, and an unexpected situation may be encountered, at the moment, the data transmission center sends the motion information to the data processing center according to a high-frequency transmission rate, so that the motion state change of the pay-off tackle in a short time can be truly reflected; or when the numerical value of the motion information is larger than or equal to a second preset threshold value, the stress state of the paying-off tackle is close to the limit bearing capacity of the paying-off tackle at the moment, and the data transmission center is required to send the motion information to the data processing center according to the high-frequency transmission rate, so that the working state of the paying-off tackle can be timely warned.
And when the variation of the motion information is smaller than a first preset threshold value or when the motion information is smaller than a second preset threshold value, receiving the motion information sent by the data transmission center at a low-frequency transmission rate.
In another example of the present invention, in order to reduce the data transmission amount and reduce the power consumption of the data acquisition and transmission module, when the variation of the acquired motion information is smaller than a first preset threshold level, or when the motion information is smaller than a second preset threshold, which indicates that the operation of the pay-off tackle is normal at this time, the data transmission frequency is automatically reduced, and the data transmission center sends the motion information to the data processing center at a low frequency transmission rate.
It is worth mentioning that the data transmission center sends the motion information to the data processing center in a manner of wireless transmission through a 4G or 5G network.
Optionally, the motion information includes stress information and inclination information, the preset simulation information includes normal stress information and normal inclination information, and the step 102 may include replacing with the following step 202 and 203:
in an example of the invention, after the data processing center receives the motion information sent by the data transmission center, in order to perform the danger early warning of the paying-off tackle in time, the motion information is matched with the preset simulation information, so that the working state of the paying-off tackle is rapidly determined, and the purpose of rapid early warning is achieved.
In a specific implementation, the motion information includes stress information and inclination information, and the preset simulation information may include normal stress information and normal inclination information. The stress information reflects the pressure on the corresponding position of the paying-off pulley groove connected with the sub-conductor. When the stress information fails to be matched with the normal stress information, the situation that the sub-wires of the paying-off tackle are possibly subjected to tension change and clamped at the moment is indicated, and the working state of the paying-off tackle is determined to be an abnormal working state at the moment; and the inclination angle information reflects the posture of the paying-off tackle, when the inclination angle information fails to be matched with the normal inclination angle information, the inclination angle of the paying-off tackle is proved to be abnormal, and the working state of the paying-off tackle can be determined to be an abnormal working state.
It is worth mentioning that the preset simulation information can establish a paying-off model according to an actual paying-off environment, the paying-off tackle is operated in the paying-off model, and the preset simulation information of the paying-off tackle in the normal operation process, namely the normal stress information and the normal inclination angle information of the paying-off tackle at each position, is obtained by adjusting the wiring process of the paying-off tackle in the model.
In another example of the present invention, when the stress information is successfully matched with the normal stress information and the inclination information is successfully matched with the normal inclination information, it indicates that the working state of the pay-off tackle at this time is consistent with the running process of the preset simulation information, and determines that the working state of the pay-off tackle is a normal working state.
And step 204, outputting a danger early warning signal when the working state is an abnormal working state.
Optionally, the danger warning signal includes a force warning signal and a tilt warning signal, and the step 204 may include the following sub-steps S11-S13:
a substep S11, outputting a stress early warning signal when the stress information fails to be matched with the normal stress information; the stress early warning signal is used for displaying the position of the abnormal sub-conductor corresponding to the stress information;
in an optional embodiment of the invention, when the stress information is failed to match with the normal stress information, it indicates that the stress of the wheel groove of the pay-off pulley at the time is uneven, and a phenomenon that the sub-conductor jumps or loosens may exist, and at the time, a stress early warning signal is output, and the position of the abnormal sub-conductor corresponding to the stress information is displayed, so that the abnormal sub-conductor can be processed subsequently.
A substep S12, outputting an inclination angle early warning signal when the inclination angle information fails to be matched with the normal inclination angle information; the inclination angle early warning signal is used for displaying the posture of the pay-off tackle corresponding to the inclination angle information;
in another optional embodiment of the present invention, when the inclination information fails to match with the normal inclination information, it is marked that the attitude inclination of the pay-off tackle at this time exceeds the maximum inclination angle, and may impact a cross arm of an iron tower for wiring, and at this time, an inclination warning signal is output, the attitude of the pay-off tackle corresponding to the inclination information is displayed, and a worker is informed that the working state of the pay-off tackle at this time is abnormal, so as to adjust the attitude of the pay-off tackle subsequently.
And a substep S13, outputting a stress early warning signal and an inclination angle warning signal when the stress information fails to be matched with the normal stress information and the inclination angle information fails to be matched with the normal inclination angle information.
When the stress information fails to be matched with the normal stress information and the inclination information fails to be matched with the normal inclination information, the situation that the paying-off tackle is abnormal in posture when the stress of the wheel groove of the paying-off tackle is uneven is shown, and a stress early warning signal and an inclination early warning signal are output at the moment to warn accidents, so that a worker can avoid the accidents in time.
Further, the method may further include the following steps S21-S22:
step S21, when the stress early warning signal is output, stopping the paying-off tackle and adjusting the paying-off speed of the abnormal sub-conductor corresponding to the position of the abnormal sub-conductor;
in the embodiment of the invention, when the stress early warning signal is output, in order to avoid further accidents, the paying-off tackle is stopped, specifically, the data processing center controls the tractor to stop the paying-off tackle emergently, and then the paying-off speed of the abnormal sub-conductor corresponding to the position of the abnormal sub-conductor is adjusted, for example, the paying-off speed of the non-abnormal sub-conductor is reduced, so that whether the stress early warning signal still occurs or not is further judged, and the safety of the paying-off process is improved while the wiring efficiency is ensured not to be influenced as much as possible.
And step S22, stopping the paying-off tackle when the inclination angle alarm signal is output.
In another embodiment of the invention, when the inclination angle alarm signal is output, the paying-off tackle is directly stopped, and further deterioration of the attitude of the paying-off tackle is avoided.
In the embodiment of the invention, the motion data of the paying-off tackle is acquired through a strain sensor and a double-shaft tilt sensor and is transmitted to a data transmission center through a cable, and the data transmission center adjusts the sending rate according to the variable quantity or the numerical value of the current motion data and sends the motion information to a data processing center so as to reduce the resource consumption as much as possible; judging whether the working state of the pay-off tackle is abnormal or not in a data processing center according to the matching result of the stress information and the normal stress information and the matching result of the inclination angle information and the normal inclination angle information, judging the type of the output danger early warning signal and outputting a corresponding danger early warning signal when the working state of the pay-off tackle is in an abnormal working state, and executing processing operation on the pay-off tackle to prevent further deterioration of an accident situation, thereby solving the technical problem that the danger early warning cannot be timely carried out on dangerous points in the pay-off construction process due to the fact that a pay-off system is complex and the working state of the pay-off system cannot be accurately known in the prior art, and more accurately and timely realizing the danger early warning and processing of the pay-off tackle.
Referring to fig. 4 and 5, fig. 4 shows a stress schematic diagram of a normal working state of the pay-off tackle in the embodiment of the invention, and fig. 5 shows a stress schematic diagram of an abnormal working state of the pay-off tackle in the embodiment of the invention.
In the specific implementation, the time-course change of the pressure applied to the wheel grooves 1-5 is picked up through the external strain sensor of the pulley beam, the tension time-course change of each sub-conductor is used as the pressure of each wheel groove, the sub-conductor is applied with the pressure q of the conductor at each wheel groove, namely, a fixed position, and the stress f1 and f2 of the beams at the two sides of the pulley are shown in fig. 4.
Once a groove jumping accident occurs, the sub-conductor does not act on the corresponding wheel groove of the pulley at a predetermined position, that is, the acting point of q changes, for example, the sub-conductor of the 5 th wheel groove jumps to the 4 th wheel groove, and the pressure of the 4 th wheel groove becomes 2q, which causes the stress f1 and f2 of the brackets at the two sides of the pulley to change (as shown in fig. 5), and the two strain sensors mounted on the cross beam can accurately identify the stress change of the bracket of the pulley to perform early warning, and judge the change of f1 and f2 according to the theoretical calculation condition, and determine whether the sub-conductor has the groove jumping phenomenon and the loosening phenomenon. If the tension of a certain sub-conductor changes and the situation of clamping occurs, the pressure of the corresponding position of the wheel groove can be increased, the situation can be sensed directly through a strain sensor on the support, and then dangerous points can be pre-warned, particularly the advancing state of each sub-conductor of the pay-off system under special working conditions such as large height difference, large corners and crossing positions, so that the data processing center can comprehensively judge whether the sub-conductor jumps and is locally clamped.
