[0032] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 1-5 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0033] like Figure 1-5 As shown: A method for remote transmission of underwater signals in a wireless cascade manner, including a signal detection mechanism, a signal collection mechanism and a host computer, all of the signal collection mechanisms are connected in succession in a cascade manner, the signal detection mechanism detects various underwater signals and transmits the information to the signal collection mechanism in a wireless manner, and the signal collection mechanism then collects all the signals and transmits them to the host computer.

At the same time, since all information is transmitted to one terminal, on the one hand, at least one terminal host computer 15 needs to be set up within a certain fixed range, and on the other hand, all terminal host computers 15 are not connected to each other, the information is disordered, the connection method is chaotic, and program loopholes are prone to occur. Therefore, a new and more organized connection method and information transmission method are needed, including a signal detection mechanism, a signal collection mechanism and a host computer 15, all of which are signal receiving The collecting mechanisms are connected in succession in a cascade manner. The signal detection mechanism detects various underwater signals and transmits the information to the signal collecting mechanism wirelessly. The signal collecting mechanism then collects all the signals and transmits them to the host computer 15. Obviously, the wireless cascade transmission method is information cumulative transmission, which can prevent information transmission loss and reduce the number of host computers 15, thereby improving the convenience of information transmission. However, this method requires setting the corresponding number of transmission connections and setting the corresponding positional relationship. At the same time, the frequency of single information transmission should be controlled to prevent the system from being disordered due to excessive amount of information at the rear.

[0035] like Figure 1-5As shown, a remote transmission device for underwater signals in a wireless cascade mode is provided. In order to smoothly carry out the remote transmission of the underwater wireless signals in a cascade mode, a corresponding structure should be provided. At the same time, the structure should be easy to install and uniformly arranged underwater to make the information collection more complete. Since biological or non-biological objects are prone to cause certain signal obstruction underwater, a corresponding structure needs to be set to solve this problem, including a signal detection mechanism arranged underwater and a signal collection mechanism arranged on the water surface. The signal detection mechanism and the signal collection mechanism are fixed by a vertical steel wire rope 11. The signal detection mechanism includes a lead fish, a water surface switch 1 and a current meter 2 are arranged on the upper side of the lead fish, a bottom switch 3 is arranged at the bottom of the lead fish, and a depth sounder 4 and a laser transmitter 5 are arranged at the bottom of the lead fish; the signal collection mechanism includes a buoy 7, a laser collector 6 matched with the laser transmitter 5 is arranged on the buoy 7, a collection and transmission device is built in the buoy 7, and a solar panel 9 is arranged on the upper surface of the buoy 7, the buoy 7 is a PVC pipe, and the bottom of the buoy 7 is sealed with a rubber bottom. Obviously, the vertical wire rope 11 should have a certain anti-rust structure. Therefore, the material can be selected as stainless steel or tin-aluminum electroplated on the outside of the vertical wire rope 11 for rust prevention. The lead fish is to ensure that the signal collection structure is completely underwater, to ensure that various data such as temperature are detected correctly during detection, thereby ensuring the accuracy of the transmitted data. The material of the lead fish can also be made of other materials, such as stainless steel, which can also meet the use requirements. The depth sounder 4 can use an ultrasonic depth sounder 4, or other structures can be used for depth testing. The bottom density of the lead fish should be greater than the upper density, thereby ensuring that the lead fish is in an underwater state and that the depth sounder 4 is at the bottom of the lead fish. The float 7 can be a round tube or a square tube, both of which can meet the use requirements. The material of the rubber bottom should be rubber or other types and types of rubber, and the density should be greater than the density of the PVC material, so as to ensure that the float 7 is in a vertical state. The solar panel 9 can be set as one piece or multiple pieces. The bottom of the solar panel 9 should be provided with wires, and the wires should pass through the float 7 and be connected to the internal lithium battery. At the same time, the top of the float 7 should be provided with a corresponding sealing structure to ensure that the float 7 will not be flooded due to rain or waves when used on the water surface, affecting the service life of the internal components.

[0036] According to one embodiment of the present invention, Figure 1-5As shown, in order to protect the laser emitter 5 potentially underwater and prevent water from entering the laser emitter 5 to affect its normal use, a corresponding structure should be provided to protect it to a certain extent. The lead fish is in the shape of a fish, and the laser emitter 5 is fixedly arranged above the head of the lead fish.

A water drop-shaped shield 12 is arranged on the lead fish, and a waterproof transparent window 13 is arranged on the water drop-shaped shield 12. The laser emitter 5 is fixedly arranged in the water drop-shaped shield 12. Obviously, the lead fish can also be set to other shapes, such as a hemispherical shape or an olive shape. type, and can also meet the use requirements. The built-in laser light of the laser transmitter 5 can also be set to other colors, and can also be set to infrared light or ultraviolet light, and can also meet the use requirements.

The waterproof transparent window 13 can use a glass structure or a crystal structure, and both can meet the light transmission use requirements. The waterproof transparent window 13 and the teardrop-shaped shield 12 should be fixedly sealed and connected, or the entire teardrop-shaped shield 12 can be set to a transparent structure, and the function can be achieved.

All acquisition and transmission devices can be arranged into 4 groups in a certain order, or they can be set to other numbers, which can also meet the requirements. At the same time, in order to ensure that the acquisition and transmission devices can be smoothly connected, there should be corresponding positional relationships between the acquisition and transmission devices in adjacent connection relationships, such as setting corresponding winding objects 10 for position restrictions to ensure that they are within the range of signal transmission to prevent information transmission interruption.

[0038] According to one embodiment of the present invention, Figure 1-5As shown, in order to enable the collection and transmission equipment in the buoy 7 to work continuously, a corresponding structure should be provided to add energy thereto.

Obviously, the lithium polymer battery 14 can also be modified to other batteries, such as graphene batteries, which can also meet the use requirements. The charging controller can be set to automatically cut off the power when it is fully charged, and automatically connect when the power is not fully charged, so as to increase the service life of the battery. The structure above the water surface and the structure under the water surface can use two power sources, or they can use the same power source, both of which can meet the use requirements.

[0039] The method of using the present invention is as follows: all devices are distributed in the water according to a certain range and order, and then by turning on all switches, all detection mechanisms on the lead fish start to work and start measuring and collecting various data in the water, and then the signal is transmitted to the laser receiver through the laser transmitter 5, and the laser receiver sends the information to the collection and transmission device, and then the signal is transmitted to the next collection and transmission device through the built-in wireless transparent transmission adapter 8 of the collection and transmission device. The device collects the signal in the signal collection mechanism where the device is located, and at the same time transmits the signal of the previous collection and transmission device until it is transmitted to the host computer 15.
