Fishing is an outdoor sport activity which is very strong in technology and specialty and depends on experience, fishes are foraged and move in which water area and water layer, and different fishing enthusiasts have different judgments. Therefore, fishing enthusiasts often have certain uncertainty when going out for fishing, for example, two people use the same bait and fishing tackle in the same water area or even the same fishing position, and the fish catch has a difference in the natural soil due to different judgments on fish shoal position, water layer depth and fish species. Many anglers are left alone (colloquially referred to as "none" and "air force") because they do not know whether there are fish in the water, where the fish school is, or the fish school is too far off-shore. The existing fishing method has the defects that the existing fishing method has insufficient perception on the position and depth of a fish school in water, and experienced people are often required to guide the fishing enthusiasts on site, so that the fishing enthusiasts hope that the bait can be thrown to a place close to the movement of the fish school as far as possible.

When the invention is used, a fishing fan remotely controls the ship body 1 to freely run on the water surface by the hand-held remote controller 8, and when the ship body 1 runs to a water area above a fish school position, the computer system 3 on the ship body 1 receives a remote control instruction to start an automatic (or manual) fishing mode. The automatic fishing mode comprises the automatic navigation without destination of the ship body 1, and according to the feedback of sonar signals, the automatic detection of fish school, the automatic paying-off and baiting, the automatic induction of fish getting on the hook and the tightening of fish line are realized. The automatic fishing reel 5 is used for paying off and baiting to a water layer where a fish school is located, the underwater high-definition camera 4 transmits pictures to the handheld remote controller 8 for observation, the automatic induction tightener 6 automatically tightens fish in the fishhook 14 according to the vibration condition of the fishing line, and then the remote control ship body 1 drives back to the shore to complete the whole process of automatic fishing.

The manual fishing mode is that the ship body 1 is driven to sail according to a selected route through the handheld remote controller 8, a fish biting hook is observed on a display screen of the handheld remote controller 8 through the underwater high-definition camera 4, and then the automatic fishing reel 5 is controlled to rotate through the handheld remote controller 8 to tighten a fishing line so as to achieve the purpose of fishing.

Sonar fish finding ware 2 is initiative scanning formula sonar equipment, including sound wave emitter and receiving arrangement to 360 degrees to launching ultrasonic signal under water as the center hull 1, and receiving arrangement will reflect back ultrasonic signal conversion and become the signal of telecommunication, transmits handheld remote controller 8 through computer system 3.

After the automatic fishing line wheel 5 is started to automatically (or manually) fish, the computer system 3 drives the sonar signal of the sonar fish finder 2 to descend the fishing line 13 to the depth of the water layer where the fish school is located together with the underwater high-definition camera 4 and the vibration sensor 7.

The underwater high-definition camera 4 feeds back underwater fish swarms, target fish baiting and other conditions in real time, and video signals are sent to a display screen of the handheld remote controller 8 through a WIFI signal transmitter of the computer system 3.

The automatic induction tightener 6 induces the vibration of the fishhook and the fishline through the vibration sensor 7 integrated on the fishline 13, the vibration amplitude of the fishline after a fish eats bait becomes large, the computer system 3 sends an instruction to the automatic fishing line wheel 5 to tighten the fishline after receiving a fishing signal transmitted by the automatic induction tightener 6, the fishing line is simultaneously transmitted to the handheld remote controller 8 to be subjected to acousto-optic reminding, the manual fishing mode can be switched to at any time, and a person behind the middle fish can drive the boat body 1 and the fish to play according to the size of the fish.

Handheld remote controller 8 can realize through computer system 3 that remote control hull 1 traveles, analysis sonar signal data, and the distribution point, size, position and the water layer degree of depth etc. of graphical show fish school show the video picture under water that high definition digtal camera 4 returned under water, switch the fishing mode, carry out WIFI wireless both-way communication etc..

The sonar fish finder 2 on the hull 1 is mainly based on an active sonar scanning technology, actively emits sound waves, receives the sound waves after encountering objects to reflect, and calculates the depth or distance of the objects from a signal source through the time difference of emission to reception.

The acoustic wave has a characteristic that it has a smaller propagation loss in water and a faster propagation speed than air (about 1500 m/s), which is a characteristic that the general electromagnetic wave or light wave does not have. The sonar can detect the echo signal with the depth of 5000 meters, so that any light wave and electromagnetic wave at a depth cannot be reached in water.

All that sonar fish finding ware 2 launches is the single beam, and the beam is big end down's conical shape, and all objects that are shone in the within range of this conical surface all can feed back and form the echo, and sonar fish finding ware sets up 77KHz and 200KHz commonly used. The beam cone angle is different at each frequency and the illuminated area is different.

In the internal setting of the sonar fish finder 2, a program is previously provided for possible substances on the sea bottom or in the water, and then the frequency spectrum corresponding to the echo is classified and compared, and then displayed. For the fish aimed by the invention, the size of the fish is defined by the volume space of the fish and the space of swim bladder.

Different working frequencies actually have different expressions for the reflected echoes of the fish. Therefore, the invention uses 77KHz and 200KHz instead of reflecting the strongest frequency band of 40-50 KHz, and is also the reason for meeting the two aspects of technical realization difficulty and observation requirement.

The fishing reel (winder) is an important part in fishing gear, and can be divided into a spinning wheel, a water drop wheel, a road wheel, a rock fishing wheel and the like. On the basis of the most familiar water droplet wheel, the invention adopts the steering engine to drive the fish wire coil, and the steering engine is controlled by the computer system 3 on the ship body 1 to manufacture the automatic fish wire wheel 5.

The computer system 3 collects echo signals of the sonar fish finder 2 to obtain the water layer depth of fish school distribution, and the depth value is converted into a pulse width modulation control signal of an automatic fish line wheel steering engine through calculation of a baiting strategy algorithm, so that the steering engine is controlled to rotate for a given number of turns at a given speed, and the lowering depth of the fish line 13 is realized.

The traditional fishing rod is generally provided with a float, people judge the bait eating condition of the fish through the action of the float, so that the time for lifting the fishing rod or taking up the fishing rod is determined, sometimes, the action of the float is very fine, people are required to judge whether the fish catches the bait or not and even what fish is biting the bait according to abundant fishing experience, and therefore the requirement of the existing fishing rod on the fishing experience of people is high.

The invention is characterized in that a vibration sensor 7 for sensing the pulling of a fishhook is arranged on a fishing line 13 of an automatic fishing line wheel 5, and the vibration sensor 7 is connected with an automatic induction tightener 6 in a wired mode and is integrated on the fishing line 13. When the vibration signal that vibration sensor 7 returned surpassed the threshold value of settlement, auto-induction tightener 6 sent the signal for computer system 3 on the hull 1, computer system 3 sends the instruction and tightens up the fish tape for automatic fish tape wheel 5 fast, prevents the fish and unhook to signal and carry out the reputation and remind for handheld remote controller 8, remind the remote control hull 1 of fisher to lean on the bank to receive the fish.
