Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to overcome the problems in the prior art, the embodiment of the invention provides a river cable monitoring method and device, and the invention is characterized in that whether a target ship body can safely pass through a river or not is judged based on the passing data of the target ship body acquired by a detector and the like, namely, whether the target ship body can touch a cable positioned above the river or not, and a ship which can touch the cable is not allowed to pass through, so that the river cable is monitored, and the safety of the river cable crossing is ensured.
Fig. 1 is a flow chart of a river cable monitoring method according to an embodiment of the present invention. As shown in fig. 1, the method includes: and step S101, if the cable which can pass through the target position of the target ship body is judged and known according to the water height and the historical data of the target ship body, allowing the target ship body to pass through the first position.
Wherein the second location is located between the first location and the target location; the second location is adjacent the target location.
It should be noted that, the execution body of the embodiment of the present invention is a river cable monitoring device.
If the problem of whether the target hull can pass through the cable at the target position is not considered, the hull passes through the first position, the second position and the target position in sequence along the sailing direction of the target hull.
In the air of the target position, cables crossing the river exist, and the cables are cables of the target position.
The second location is relatively close to the target location. Preferably, the distance between the second location and the target location may be 1-2 hulls.
The gates may be disposed at the first and second positions, respectively. When the target ship body runs to the first position or the second position, the gate is closed; if the judgment result is that the target ship body is allowed to pass, the gate is opened, and the target ship body can continue to run forwards; if the judgment result shows that the target ship body is not allowed to pass, the gate is kept closed, and the target ship body is not allowed to continue to run forwards.
When the target ship body runs to the first position, whether the target ship body can pass through the cable at the target position is judged for the first time.
The cable capable of passing through the target position, also called as a normal cable passing through the target position, refers to a cable which does not touch the target position when the ship body passes through the target position.
A cable that cannot pass through the target location, also known as a cable that passes through the target location in an ultrahigh manner, refers to a cable that encounters the target location as the hull passes through the target location.
The water height of the target ship body can be obtained through data acquired by a detector arranged at the first position, and can also be obtained through active reporting of the target ship body.
According to the water height and the historical data of the target ship body, whether the target ship body can pass through the cable at the target position can be judged.
For example, the judgment result can be obtained according to whether the hull of the water height passes through the record of the cable of the target position in the historical data; and the comprehensive judgment can be carried out by combining whether the ship body of each water height including the water height passes through the record of the cable of the target position in the historical data, so as to obtain a judgment result.
Historical data includes a record of whether the hull of each water level passed the cable at the target location.
And if the result of the first judgment is that the target ship body can pass through the cable at the target position, allowing the target ship body to pass through the first position and continuing to run forwards.
And S102, if the cable which can pass through the target position of the target ship body is judged and known according to the data of the target ship body acquired at the second position, allowing the target ship body to pass through the target position.
Specifically, when the target hull is driven to the second position, a second determination is made as to whether the target hull can pass through the cable of the target position.
The second position may be where the detector is arranged. The detector is used for detecting whether the target ship body is ultrahigh, namely judging whether the height of the part of the target ship body above the water surface (namely the water height) is larger than the cable height of the target position.
The cable height refers to the height of the cable from the water surface.
If the height of the part of the target ship body above the water surface is smaller than the cable height of the target position, the result of the second judgment is that the target ship body can pass through the cable of the target position. At this point, the target hull is allowed to pass the first location and continues to travel forward until it passes the target location.
According to the embodiment of the invention, whether the target ship body can pass through the cable of the target position or not is judged twice through the water height of the target ship body, the historical data and the data of the target ship body, the target ship body with the result of the two judgments is allowed to pass through the target position, a scientific and effective new thought and means are provided for detecting the ship body height in the river channel, the running ship body height in the river channel can be effectively obtained, whether the river channel can pass safely or not is estimated, and intelligent analysis and estimation are realized, so that the efficiency of monitoring the cable of the river channel is low, the cost of monitoring the cable of the river channel is reduced, the effect of monitoring the cable of the river channel is improved, and the electricity utilization safety across the river channel can be more effectively ensured.
Based on the above embodiments, the specific steps of determining, according to the water height and the historical data of the target hull, a cable for knowing that the target hull can pass through the target position include: if the historical data is inquired and the record of the cable passing through the target position of the ship body with the ultrahigh water height does not exist, inputting the water height of the target ship body into a probability prediction model, and outputting the probability that the target ship body can pass through the cable of the target position.
Wherein the probabilistic predictive model is derived from historical data.
Specifically, a probabilistic predictive model may be built based on historical data.
For each water level present in the historical data, taking the proportion of the cables of the ship body of the water level passing through the target position normally as the probability of the cables of the ship body of the water level passing through the target position.
And taking the water height as an independent variable, taking the probability of the ship body passing through the cable at the target position as the dependent variable, fitting historical data according to a preset function, and establishing a probability prediction model.
The preset function may be a linear function, a hyperbolic function, an inverse function, or the like.
For example, the fitting may be performed with y=a+b (1/X); wherein Y represents the probability of the hull passing through the cable at the target location; x represents the water height of the hull; a. b is a parameter, and the value of the parameter can be obtained through fitting.
Inquiring historical data, and if the historical data contains the water height of the target ship body and the ship body of the water height normally passes through the cable of the target position, determining that the probability that the target ship body can pass through the cable of the target position is 1.
Inquiring historical data, if the historical data does not contain the water height of the target ship body, inputting the water height of the target ship body into a probability prediction model, and outputting the probability of a cable which corresponds to the water height and can pass through the target position.
If the probability is greater than a preset probability threshold, knowing that the target ship body can pass through the cable at the target position.
Specifically, whether the probability that the target ship can pass through the cable at the target position is larger than a preset probability threshold value is judged.
The probability threshold value can be determined according to actual conditions, and the specific value of the probability threshold value is not limited in the embodiment of the invention. For example, the probability threshold may be 90%.
If the result of the first judgment is larger than the target position, determining the result of the first judgment as the cable which can pass through the target position by the target ship body.
According to the embodiment of the invention, whether the target ship body can pass through the cable at the target position or not is primarily judged through the water height and the historical data of the target ship body, the target ship body with the judgment result being capable of continuously running forwards is allowed, scientific and effective new thought and means are provided for detecting the ship body height in the river channel, the running ship body height in the river channel can be effectively obtained, whether the river channel can be safely passed or not is evaluated, intelligent analysis and evaluation are realized, so that the efficiency of monitoring the cable of the river channel is low, the cost of monitoring the cable of the river channel is reduced, the effect of monitoring the cable of the river channel is improved, and the electricity utilization safety of the river channel can be effectively ensured.
Based on the above-mentioned embodiments, the specific steps of determining, according to the data of the target hull acquired at the second location, that the target hull is able to pass through the cable of the target location include: and judging whether the water height of the target ship body is smaller than the height of the detector from the water surface according to the detector positioned at the second position.
The height of the detector from the water surface is equal to the sum of the height of the cable at the target position from the water surface and the preset height difference.
Specifically, due to a certain fluctuation of the water surface, when the detector is arranged at the second position, the height of the detector from the water surface is set as the sum of the height of the cable at the target position from the water surface and the preset height difference.
The height difference can be determined according to actual conditions, and the specific value of the probability threshold is not limited in the embodiment of the invention. For example, the height difference may be 0.3 meters.
The detector at the second position can be an infrared correlation detector, an image detector and the like.
When the target ship body runs to the second position, whether the water height of the target ship body is smaller than the height of the detector from the water surface can be judged through whether the infrared rays emitted by the infrared correlation detector are blocked.
If the ship body is not blocked, the water height of the target ship body is smaller than the height of the detector from the water surface; if blocked, the water height of the target ship body is larger than the height of the detector from the water surface.
When the target ship body runs to the second position, an image above the height of the detector from the water surface can be acquired through the image detector, and whether the water height of the target ship body is smaller than the height of the detector from the water surface is judged according to whether the target ship body appears in the image.
If the ship body does not appear, the water height of the target ship body is smaller than the height of the detector from the water surface; if present, this indicates that the water level of the target hull is greater than the detector level from the water.
If yes, knowing the cable at the target position through which the target ship body can pass.
Specifically, if the water height of the target ship is smaller than the height of the detector from the water surface, determining the result of the second judgment as a cable at the target position through which the target ship can pass.
According to the embodiment of the invention, whether the target ship body can pass through the cable at the target position is judged again through the data of the target ship body, the target ship body with the judging result being capable of continuously running forwards is allowed, scientific and effective new thought and means are provided for detecting the height of the ship body in the river channel, the height of the running ship body in the river channel can be effectively obtained, whether the river channel can pass safely or not is evaluated, intelligent analysis and evaluation are realized, and therefore, the efficiency of monitoring the cable of the river channel is low, the cost of monitoring the cable of the river channel is reduced, the effect of monitoring the cable of the river channel is improved, and the electricity safety across the river channel can be more effectively ensured.
Based on the above-mentioned contents of each embodiment, outputting the probability that the target ship can pass through the cable at the target position further includes: if the probability is smaller than the probability threshold, knowing that the target ship body cannot pass through the cable at the target position.
Specifically, if the probability output by the probability prediction model is smaller than the probability threshold, determining the result of the first judgment as a cable which cannot pass through the target position of the target ship body. At this time, the target hull is not allowed to pass through the first position, and is not allowed to continue traveling forward.
According to the embodiment of the invention, whether the target ship can pass through the cable at the target position or not is primarily judged according to the water height and the historical data of the target ship, the target ship which cannot be judged is not allowed to continue to run forwards, the situation that the ultrahigh ship passes through the target position and the cable at the target position is damaged can be avoided, and therefore the electricity safety of a river crossing can be effectively ensured.

Specifically, the historical data is queried, if the historical data contains the water height of the target ship body, and the ship body with the water height cannot normally pass through the cable at the target position, namely, the ship body with the water height exceeds the record of the cable at the target position, the result of the first judgment is directly determined as the cable which cannot pass through the target position by the target ship body.
Inquiring historical data, if the historical data does not contain the water height of the target ship body, inputting the water height of the target ship body into a probability prediction model, and outputting the probability of a cable which corresponds to the water height and can pass through the target position; if the probability is smaller than the probability threshold, determining the first judgment result as that the target ship body cannot pass through the cable at the target position.
