The invention discloses an AIS (automatic identification system)-based water area security protection alarm method. The method includes the following steps that: a water area where facilities requiring security protection is divided into grids, a security protection management table is established according to the coordinates of the grids, the coordinates of the facilities and the characteristic parameters of facilities, and an early warning and alarm parameter setting table is established; when ship information transmitted from a ship-borne AIS system is received, various kinds of parameters are extracted from the information, and the coordinates of the facilities and the appearance characteristic parameters of the facilities in the security protection management table are retrieved by using ship position coordinates; and distances between a ship and the facilities are obtained by using different algorithms according to different facilities, and whether the distances between the ship and the facilities and the speed of the ship satisfy set early warning or alarm conditions are judged. With the AIS (automatic identification system)-based water area security protection alarm method of the invention adopted, water surface facilities and underwater facilities can be protected; and early warning or alarm conditions can be set flexibly by a user, so that early warning or alarm against dangerous ships can be carried out fast and accurately. The method has the advantages of wide application range and flexible use, can provide security protection for water area facilities and has a certain economic value.

The invention discloses a water supply device for a large-scale breeding farm, which includes a breeding room body, horizontal dividing plates are fixedly connected to both sides of the inner wall of the breeding room body, and vertical dividing plates are also connected between the horizontal dividing plates. The sub-board and the vertical sub-board divide the breeding room body into a plurality of breeding rooms, and the breeding rooms are arranged in rows, and passages are also arranged between the breeding rooms in each row, and a water supply tank is also arranged on one side of the breeding room body. The input end of the water supply tank is connected with a water inlet pipe, the top surface of the water supply tank is also connected with a water pump through screws, and the water outlet pipe is connected between the input end of the water pump and the water supply tank. A water outlet pipe is connected between the water pipe, the output end of the water pump and the water distribution pipe. The invention has the advantages of reasonable design, stable operation of the water supply system, high degree of automatic control, convenient control of the water injection amount, and automatic cleaning of the water tank, which ensures the safety of drinking water for livestock.

The invention provides a vehicle water dispenser control method. When a user makes a cup make contact with a first pressure sensor on a lifting mechanism, the lifting mechanism can be triggered to godown, the cup is adaptively lifted to the portion under a water outlet end of a faucet, the water outlet end is made to be inserted into the cup, the water volume of the cup is detected, and the wateryield is determined according to the water volume of the cup; in this way, in the driving process of a vehicle, the user only needs to put the cup on the lifting mechanism with one hand, and the userdoes not need to take the cup with one hand and operate the faucet with the other hand; in the water collecting process, the water outlet end of the faucet is completely inserted into the cup so thatthe cup cannot incline, and then the phenomenon that hot water splashes to scald the user can be avoided, and the safety of water use of the user in the vehicle is improved.
