At present, the structural form of the observation buoy is mostly disc-shaped, and a ship-shaped structure is adopted at a river mouth or a sea area with a single flow direction. Due to the importance of the special observation equipment and observation data, the price of each set of observation buoy is quite high. The safety problem is the focus of great attention of the construction unit.
Buoys are required to have sufficient buoyancy to perform observation tasks at sea. The buoy body mainly comprises a steel buoy body and a buoy body made of buoyancy materials (mostly EVA foam).

However, there are several problems with this conventional water alarm technique: 1) usually, a buoy is only provided with a water alarm device, even if a plurality of water alarms are arranged, the positive electrodes and the negative electrodes of the water alarms are connected in parallel to form a mechanism and then connected to a data acquisition controller of the buoy, if any one water alarm gives an alarm, the data acquisition controller can detect current, the data acquisition controller can send an alarm to a shore station, but the method cannot accurately judge which cabin enters water, and cannot judge that a plurality of buoyancy cabins enter water; 2) at present, a water police commonly used cannot judge the water level of water entering the buoyancy compartment, only can monitor whether water enters or not, is not beneficial to a user to grasp the specific condition of water entering the buoy in time, and is not beneficial to making an accurate emergency scheme; 3) at present, a water alarm commonly used does not have an independent communication function, does not have a function of sending alarm short messages and mails to a user in time, can only send alarm information to a buoy data receiving interface of a land base station through a data acquisition controller of the buoy and according to the time sequence and frequency set by the data acquisition controller, and is single in alarm approach and not beneficial to the user to know the state of the buoy in time.

The construction and operation of the present invention will be described in detail with reference to the application of the alarm device to a target ocean observation buoy as a specific embodiment.
As shown in fig. 3-4, the water-alarm probe 10 is installed on the target buoy, specifically, the deck and above are removed, and only the buoyancy compartment under the deck is reserved. The target buoy has a two-layer buoyancy cabin structure, and the outer layer is provided with six peripheral buoyancy cabins 201 which are uniformly distributed; the two buoyancy chambers are respectively a battery chamber 202 and a data acquisition control chamber 203, wherein the battery chamber 202 is smaller, a storage battery is arranged in the buoyancy chamber, the data acquisition control chamber 203 is larger, and a data acquisition controller is arranged in the buoyancy chamber.

The water alarm control unit and the water alarm communication unit are both arranged in the data acquisition control cabin 203. As shown in fig. 5, the power module of the water alarm control unit adopts a DCDC power module, continuously provides a 1mA constant current source, and transmits the constant current source to the positive electrode 12 of the water alarm probe through the water alarm interface 21, so that a voltage change curve is formed between the positive electrode and the negative electrode of the water alarm probe 10, if the bottom of the water alarm probe 10 is connected, the voltage is 5v, which proves that water enters, the intervening resistance unit 16 becomes less as the water level rises, but the current is constant, so the voltage becomes less, and the water level is judged by the change of the voltage value. The data collection processing module of the water alarm control unit adopts an stm32f103 single chip microcomputer and also provides power for the single chip microcomputer through a power supply module. In a normal state, water does not enter the buoyancy chamber, the horizontal position of the magnetic floating ball 15 is located below the magnetic switches 17, all the magnetic switches 17 are in a disconnected state, the water alarm probe 10 is in a disconnected state, and the data collection and processing module cannot detect voltage.

The magnetic floating ball 15 can float upwards along with the rising of the water level, so that the magnetic switch 17 at the corresponding position is switched on, the intervening resistance unit 16 becomes smaller and the constant current source is switched on along with the rising of the water level and the switching on of the magnetic switch 17 at the corresponding position, so that the voltage becomes smaller, the data collection and processing module realizes the judgment of the water level by detecting the voltage, and the alarm probe for water inlet alarm positions cabin information and water level information and sends the cabin information and the water level information to a user through the water alarm communication unit.
