Description

Technical Field

[0001] The invention belongs to the technical field of ecological protection of offshore operating platforms, and in particular relates to a method and system for protecting fish on offshore operating platforms and driving away fishermen. Background Art

[0002] With the exploration of the ocean by humans, more and more structures are being built in the ocean, and offshore platforms are the most common type. The underwater columns of offshore platforms are immersed in seawater for a long time, and various marine organisms are attached to the surface, which will attract more fish to come for food. Various protected organisms at the top of the marine food chain will also often come here, and may often collide with structures in the seawater, causing casualties. At the same time, because such sea areas are rich in fish, they often attract fishing enthusiasts. Various cables and pipelines are often distributed on the seabed around offshore structures, and non-staff and ships are prohibited from approaching.

[0003] At present, two traditional methods are used to solve the above problems: one is to post safety risk notice signs around unmanned offshore platforms. The other is to use staff to shout and drive away fishermen on manned offshore platforms and post safety risk notice signs at the same time. However, the effect of these two methods is limited. Whether the fishermen can be driven away depends entirely on the quality of the fishermen. For example, some fishermen ignore warnings and continue fishing, and there is no way to drive them away. Illegal fishing near offshore platforms cannot leave evidence, and relevant personnel cannot be recorded and punished. Finally, marine animals are illegally killed, and there is also the risk of fishermen approaching and touching cables and pipelines. Summary of the invention

[0004] The purpose of the present invention is to address the problems in the prior art of a large number of fish gathering around an offshore operating platform, the risk of fish being injured, fishermen fishing near an offshore operating platform, which damages fish resources, and the risk of touching and damaging cables and pipelines, and propose a method and system for protecting fish from an offshore operating platform and driving away fishermen. The method and system of the present invention can drive away fish around an offshore operating platform to avoid fish being injured, and can also drive away fishermen, record illegal fishing, protect fish, and eliminate the dangers of fishermen approaching the offshore operating platform.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A method for protecting fish on an offshore platform and driving away fishermen, comprising the following steps:

[0007] S1: Fish protection, including fish repelling and fish collision prevention;

[0008] The fish driving method uses a sound wave emitting system to emit driving sound waves in the waters around the offshore operating platform to keep the fish away from the offshore operating platform; the duration of emitting the driving sound waves is determined according to factors that affect the gathering of fish schools;

[0009] The fish collision prevention is to use soft corrosion-resistant materials to block the columns of the offshore operation platform to prevent the fish from hitting the columns of the offshore operation platform when swimming quickly;

[0010] S2: Fishermen are driven away, including platform video recording, loudspeaker driving away, sound wave emission system activation, drone driving away, and system recording;

[0011] The platform video recording is to set up high-definition cameras around the offshore operation platform to film the approaching fishermen;

[0012] The tweeter-speaker drive-away means that tweeters are installed around the offshore operation platform, and when the high-definition camera captures a fisherman approaching by boat, a warning to drive away is played;

[0013] The sound wave emitting system is activated, that is, when the high-definition camera captures a fisherman approaching by boat, the driving sound waves recorded in the previous step are activated to drive away the fish around the offshore operation platform, so that the fisherman cannot catch any fish and leaves on his own;

[0014] The drone driving away means that when the driving away warning is invalid, the drone takes off, hovers over the fisherman's boat, and films and plays the driving away warning;

[0015] The system records the situation of fishermen approaching the offshore operating platform, and punishes the fishermen who illegally approach the offshore operating platform through the fishery administration system.

[0016] As a further technical improvement, the factors affecting the gathering of fish schools are seasonal factors, time factors, weather factors, ocean current factors and tidal factors.

[0017] As a further technical improvement, the duration of the driving sound waves is divided into at least four levels, and the scores are calculated comprehensively according to various factors affecting the aggregation of fish schools. The scores are used as the judgment of the level. The score of the duration level L of the driving sound waves can be calculated according to the following formula:

[0018]

[0019] Wherein, L is the duration level of the driving sound wave, the higher the level, the longer the duration of the driving sound wave; a1 is the seasonal factor, such as spring and autumn are generally the active seasons for fish, at this time a1 = 10*m, otherwise a1 = 5*m; a2 is the time point factor within a day, such as the time is morning or evening, then a2 = 10*m, otherwise a2 = 5*m; a3 is the air pressure factor, if the air pressure is between 1000-1200mbpa, then a3 = 10*m, otherwise a3 = 5*m; a4 is the ocean current factor, if there is an ocean current passing at this time, then a4 = 10*m, otherwise a4 = 5*m; a5 is the tidal factor, if it is high tide at this time, then a5 = 10*m, otherwise a5 = 5*m; a n are other factors; m is the compensation value of special location factors. The parameters can be manually modified according to the special marine environment. The range of m is between 0.5-2, and the default value is 1.

[0020] As a further technical improvement, when the score of the duration level L of the driving sound wave is within 25% of the total score, it is level 1, at which time the driving sound wave device is turned off, and the manual start function is retained; when the score of the duration level L of the sound wave is between 25% and 50% of the total score, it is level 2, the driving sound wave is automatically turned on, and lasts for a period of time, and then starts intermittently; when the score of the duration level L of the sound wave is between 50% and 75% of the total score, it is level 3, at which time the driving sound wave is automatically turned on, the frequency is strengthened, and the intermittent start is performed at the same time; when the score of the duration level L of the sound wave is between 50% and 75% of the total score, it is level 4, at which time the driving sound wave is automatically turned on, and the strengthened frequency is maintained for continuous output.

[0021] As a further technical improvement, the repelling sound waves include at least three different wavelength frequencies, simulating the sound waves emitted by large and ferocious fish and the sound waves of submarine earthquakes, volcanoes, etc., and are played in rotation at irregular intervals to repel fish.

[0022] As a further technical improvement, a score will be given to anglers' approach to offshore operating platforms, with the total score taking into account at least factors such as proximity distance, length of stay, and willingness to heed dissuasion.

[0023] As a further technical improvement, the score S of the situation where the fisherman is close to the offshore operating platform is calculated as follows, and the higher the score, the more serious the situation is considered;

[0024]

[0025] Among them, b1 is the distance score between the fishing boat and the offshore operating platform, b1=10*x, x is the approach distance, the closer the distance, the larger the value of x; b2 is the score of the fishing boat's stay time, b2=10*y, y is the stay time, the longer the stay time, the larger the value of y; b3 is the score of whether the fishing boat obeys the dissuasion, b2=10*z, z is the number of times it is dissuaded, the more times it is dissuaded, the larger the value of z; the values ​​of x and y are both 0-1, and the value of z is 0-3; the higher the score, the heavier the fishery punishment.

[0026] As a further technical improvement, the situation of the fisherman approaching the offshore operating platform is composed of the total score S of the fisherman approaching the offshore operating platform, the fisherman's appearance, and the vessel number, among which the fisherman's appearance is only recorded and the actual punishment target is the vessel owner.

[0027] A system for protecting fish from an offshore operating platform and driving away fishermen, using the above-mentioned method for protecting fish from an offshore operating platform and driving away fishermen; comprising setting up high-definition cameras, tweeters and drone platforms around the upper part of the offshore operating platform; setting up a sound wave generating device underwater near the offshore operating platform; setting up a control system in the operating room of the offshore operating platform; the control system has a duration rating module for driving away sound waves and a scoring module for fishermen approaching the offshore operating platform; the control system is connected to a corresponding law enforcement system of the offshore fishery administration via a wireless network; and a soft corrosion-resistant protective layer is set on the underwater columns of the offshore operating platform.

[0028] As a further technical improvement, a fixing frame is provided on the underwater column of the offshore operation platform; the fixing frame is provided with a plurality of fixing rings; the fixing ring is provided with a corrosion-resistant plastic plate; the lower part of the corrosion-resistant plastic plate is detachably fixed by the fixing ring, and the upper part is detachably fixed to the fixing frame after being bent; the fixing frames are distributed around the underwater column of the offshore operation platform. The corrosion-resistant plastic plate can be disassembled. Some large fish are relatively large in size and swim fast. These fish can easily collide with the underwater column of the offshore operation platform. At this time, they are blocked by the corrosion-resistant plastic plate to avoid collision and injury; it is better if the corrosion-resistant plastic plate can be disassembled.

[0029] Methods of using the above-mentioned offshore platform fish protection and fisherman driving away system:

[0030] The sound wave generator is turned on according to the season, time, weather, ocean currents and tides. For example, in spring and autumn, when the water temperature is suitable, fish will breed and fish will gather in groups. In the morning and evening, when the light is suitable and the water temperature is moderate, fish will gather. When the weather is fine and the air pressure is moderate, fish will gather. When ocean currents pass by or the tide rises, fish will also gather. At this time, the duration level scoring module will score according to the corresponding factors to judge the current fish gathering situation, and turn on the sound wave generator accordingly according to the level, and adjust the duration and frequency intensity to drive away the fish and avoid It prevents fish from colliding with offshore platforms, and without fish gathering, anglers will naturally not come to fish, eliminating the safety hazard of anglers approaching offshore platforms. When anglers approach offshore platforms, high-definition cameras capture corresponding images, tweeters issue warnings to drive them away, and the scoring module for anglers approaching offshore platforms scores the action of anglers approaching to fish. When the score reaches a certain level, drones are dispatched for tracking, filming and driving them away. If anglers do not leave despite repeated dissuasion, their illegal fishing will be recorded in the fishery system and the relevant personnel will be punished.

[0031] The technical solution of the present invention has the following beneficial effects:

[0032] 1. The present invention adopts the method of using sound waves to drive away the fish schools, which can drive away the fish schools around the offshore operating platform, avoid the fish gathering and collision with the underwater columns and injuries, and also make it impossible for anglers to catch fish around the offshore operating platform, so that anglers will not fish around the offshore operating platform, eliminating safety hazards.

[0033] 2. The present invention can score the gathering of underwater fish schools around the offshore operating platform according to the season, time and other conditions, and activate the corresponding sonic driving mode according to the scoring level to effectively drive away the fish schools without causing excessive harm to the fish schools.

[0034] 3. The present invention can record and score the fishermen who approach the offshore operating platform, which is conducive to the expulsion and subsequent punishment of the relevant personnel, prevents fishermen from illegally approaching the offshore operating platform, and eliminates safety hazards such as touching the cables.

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] Example:

[0040] like Figures 1-2 As shown, a plateau tobacco distribution method comprises the following steps:

[0041] A method for protecting fish on an offshore platform and driving away fishermen, comprising the following steps:

[0042] S1: Fish protection, including fish repelling and fish collision prevention;

[0043] The fish driving method uses a sound wave emitting system to emit driving sound waves in the waters around the offshore operating platform to keep the fish away from the offshore operating platform; the duration of emitting the driving sound waves is determined according to factors that affect the gathering of fish schools;

[0044] The fish collision prevention is to use soft corrosion-resistant materials to block the columns of the offshore operation platform to prevent the fish from hitting the columns of the offshore operation platform when swimming quickly;

[0045] S2: Fishermen are driven away, including platform video recording, loudspeaker driving away, sound wave emission system activation, drone driving away, and system recording;

[0046] The platform video recording is to set up high-definition cameras around the offshore operation platform to film the approaching fishermen;

[0047] The tweeter-speaker drive-away means that tweeters are installed around the offshore operation platform, and when the high-definition camera captures a fisherman approaching by boat, a warning to drive away is played;

[0048] The sound wave emitting system is activated, that is, when the high-definition camera captures a fisherman approaching by boat, the driving sound waves recorded in the previous step are activated to drive away the fish around the offshore operation platform, so that the fisherman cannot catch any fish and leaves on his own;

[0049] The drone driving away means that when the driving away warning is invalid, the drone takes off, hovers over the fisherman's boat, and shoots and plays the driving away warning;

[0050] The system records the situation of fishermen approaching the offshore operating platform, and punishes the fishermen who illegally approach the offshore operating platform through the fishery administration system.

[0051] The factors that affect the gathering of fish schools are seasonal factors, time factors, weather factors, ocean current factors and tidal factors.

[0052] The duration of the driving sound waves is divided into at least four levels. The scores are calculated comprehensively according to the factors that affect the aggregation of fish schools. The scores are used as the judgment of the level. The score of the duration level L of the driving sound waves can be calculated according to the following formula:

[0053]

[0054] Wherein, L is the duration level of the driving sound wave, the higher the level, the longer the duration of the driving sound wave; a1 is the seasonal factor, such as spring and autumn are generally the active seasons for fish, at this time a1 = 10*m, otherwise a1 = 5*m; a2 is the time point factor within a day, such as the time is morning or evening, then a2 = 10*m, otherwise a2 = 5*m; a3 is the air pressure factor, if the air pressure is between 1000-1200mbpa, then a3 = 10*m, otherwise a3 = 5*m; a4 is the ocean current factor, if there is an ocean current passing at this time, then a4 = 10*m, otherwise a4 = 5*m; a5 is the tidal factor, if it is high tide at this time, then a5 = 10*m, otherwise a5 = 5*m; a n are other factors; m is the compensation value of special location factors. The parameters can be manually modified according to the special marine environment. The range of m is between 0.5 and 1.5, and the default value is 1.

[0055] When the score of the duration level L of the driving sound wave is within 25% of the total score, it is level 1, at which time the driving sound wave device is turned off, and the manual start function is retained; when the score of the duration level L of the sound wave is between 25% and 50% of the total score, it is level 2, the driving sound wave is automatically turned on, and lasts for a period of time, and then starts intermittently; when the score of the duration level L of the sound wave is between 50% and 75% of the total score, it is level 3, at which time the driving sound wave is automatically turned on, the frequency is strengthened, and it is started intermittently; when the score of the duration level L of the sound wave is between 50% and 75% of the total score, it is level 4, at which time the driving sound wave is automatically turned on, and the enhanced frequency is maintained for continuous output.

[0056] For example, in spring, around March and April, when most fish are more active, a1 = 10*1 can be used. This period is 6 a.m., so a2 = 10*1. However, the air pressure is 700 mbpa, so a3 = 5*0.8. There is a suitable ocean current in this season, so a4 = 10*1.2. There is a low tide at this time, so a5 = 10*1.3. Finally, we put it into the formula and get

[0057] If all calculations are based on m=1.5, the highest total score is 75 points, and the 49 points for this time account for 65.3% of the total score, which is rated as level 3, and the repelling sound wave is activated according to level 3.

[0058] The driving-away sound waves include at least three different wavelength frequencies, simulating the sound waves emitted by large and ferocious fish and the sound waves of submarine earthquakes, volcanoes, etc., and are played in rotation at irregular intervals to drive away the fish.

[0059] The anglers' approach to offshore platforms is scored, with the total score taking into account at least factors such as proximity distance, length of stay, and compliance with dissuasion.

[0060] The calculation formula for scoring S for the situation of fishermen approaching offshore platforms is as follows, and the higher the score, the more serious the situation is considered;

[0061]

[0062] Among them, b1 is the distance score between the fishing boat and the offshore operating platform, b1=10*x, x is the approach distance, the closer the distance, the larger the value of x; b2 is the score of the fishing boat's stay time, b2=10*y, y is the stay time, the longer the stay time, the larger the value of y; b3 is the score of whether the fishing boat obeys the dissuasion, b3=10*z, z is the number of times it is dissuaded, the more times it is dissuaded, the larger the value of z; among them, the values ​​of x and y are both 0-1, the value of z is 0-3, the default value is 1, and it can be manually modified according to actual conditions; the higher the score, the heavier the fishery punishment.

[0063] For example, you can set x to 1 when the fishing boat is 0-50 meters close to the offshore platform, and x is minus 0.2 for every 10 meters beyond, and x is zero for every 100 meters; if the stay time exceeds half an hour, y is 1, and minus 0.1 for every 3 minutes less; z is recorded as 1 point each time it is dissuaded; when the fisherman is 35 meters close to the offshore platform, b1=10*1, the stay time is 15 minutes, b2=10*(1-0.1*5), and leaves after being dissuaded twice, then b3=10*2, after substituting it into the formula for calculation At this time, the highest score calculated according to the highest values ​​of x, y, and z is 50 points. 35 points is 70% of the highest score. In this case, the relevant personnel will be held accountable according to the corresponding punishment level.

[0064] The situation of the fisherman approaching the offshore operating platform includes the total score S of the fisherman approaching the offshore operating platform, the fisherman's appearance, and the ship number, wherein the fisherman's appearance is only recorded, and the actual punishment target is the ship owner.
