Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.
[0026] Figure 1 It is a structural schematic diagram of a river and lake supervision device provided by the embodiments of the utility model. Referring to Figure 1 , for supervising fish exploding and blasting behavior in rivers and lakes, specifically comprising:
[0027] The first device, the second device, the AI gateway module 1 and the power module.
[0028] Referring to Figure 2 , the first device and the second device are arranged at the same water bank side, and the first device and the second device are apart by a fixed distance; the first device and the second device both comprise a collection module. The collection module is used for collecting original data in water and air.
[0029] In an embodiment, the collection module comprises an air temperature sensor 5, an underwater temperature sensor 4, an underwater transducer 2 and an aerial transducer 3, the air temperature sensor 5 and the aerial transducer 3 are used for collecting original data in air, and the underwater temperature sensor 4 and the underwater transducer 2 are used for collecting original data in water.
[0030] The underwater transducer 2 and the aerial transducer 3 are used for collecting acoustic signals with a frequency band of 10Hz-20kHz; it should be noted that the blasting sound propagates at different speeds in different media, and the speed difference method is a calculation method for calculating distance by using differential speed, and the distance from the acoustic signal emitting position to the first device and the distance to the second device can be calculated according to the speed of sound in air and water and the receiving time of the collected acoustic signals.
[0031] The air temperature sensor 5 and the underwater temperature sensor 4 are used for collecting temperature data in air and water in real time, because the speed of sound is affected by temperature, so the underwater speed of sound and the speed of sound in air are corrected in real time according to the collected temperature data, and the calculation accuracy is improved.
[0032] The AI gateway module 1 comprises a communication module and a data processing module, the communication module is electrically connected with the collection module, and the original data in air and the original data in water are processed in the data processing module.

[0034] The AI gateway module 1 is connected with the air temperature sensor 5 and the underwater temperature sensor 4 through the RS-485 bus to acquire temperature data.
[0035] The first device and the second device communicate through the wireless communication module 1-3, which has WIFI function and can send and receive signals. Data interaction can also be carried out between the module and the remote terminal to remind relevant personnel of the state of the river and lake in real time, so that they can timely prevent fish blowing and blasting behaviors.
[0036] In one embodiment, the data processing module includes a DSP module 1-2 for converting the original data in the air and the original data in the water into time domain data and frequency domain data, and a computing power module 1-4 for feature extraction of the time domain data and the frequency domain data.
