Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-6, the present invention is a drowning warning device.
The device at least comprises a water pressure collector, a drowning judging and positioning system and an early warning system, and can refer to fig. 6.
When drowning occurs, the nose and mouth of the drowning person are all placed under water, so the water pressure collector needs to be arranged near the nose and mouth; for example at the front end of the swimming cap or on swimming goggles. Reference may be made in particular to fig. 1 and 2.
The water pressure collector is composed of a water pressure sensor, a power supply module and a signal generating module, and can be specifically referred to fig. 3, and is used for collecting information about water pressure changes and continuously sending the information to the outside at a certain frequency.
Preferably, in order to reduce the sending frequency and reduce energy consumption, data can be sent when the water pressure changes greatly, for example, water flows out to water enters, water enters to water exits, and water pressure information is sent when the water pressure changes greatly along with the depth after entering; because the equipment needs to work in water, the power supply module needs to support wireless charging and transmit data with low energy consumption through the signal transmission module;
the water pressure sensor is used for sensing the water pressure;
the power supply module is used for providing electric power support for the water pressure collector;
the signal sending module sends the water pressure detected by the water pressure sensor to the outside at a certain frequency. Specifically, the information sent by the signal generator includes two parts: equipment identification + water pressure information. The device identification is key and is important information for judging whether drowning occurs or not. Having had equipment identification, can directionally sending early warning information to the supervisory personnel, for example, the head of a family information is bound with this equipment, in case drowned emergence, can take place early warning information for the head of a family.
The drowning judging and positioning system consists of a signal receiver, a judging module, a positioning module and a monitor, and is used for judging the occurrence of a drowning event and positioning the position of a drowning person. The basic principle is as follows: the water pressure value in the air is about zero, and the water pressure in the water is a certain positive value which is larger than zero, so that the water entering or water exiting of the equipment can be judged according to the water pressure, if the equipment enters the water, whether the equipment is drowned or not is judged according to the continuous water entering time, and the most probable drowning person in a monitoring picture is positioned through machine vision by combining a positioning module, so that the drowning judgment and positioning are formed;
wherein, the signal receiver is used for receiving signals, and 1 or more signal receivers are arranged around the swimming pool according to the area of the swimming pool so as to receive all information in the swimming pool;
the judging module is connected with the signal receiver and used for judging whether the signal received by the signal receiver is drowned or not;
the positioning module is used for extracting a monitor picture and positioning a possible drowner in the monitor picture.
The swimming pool monitoring device further comprises a monitor, the monitor is connected with the positioning module, the monitor is installed above the swimming pool and can monitor the activity condition of the swimming pool at a large visual angle, and the positioning module can call out real-time pictures at any time according to needs.
When the drowning judging and positioning system is used, the drowning judging and positioning system is connected with the signal receiver, and once the signal receiver receives water pressure information, the water pressure information is immediately sent to a judging module in the drowning judging system to judge whether the current equipment enters water or leaves water. If the water pressure of the current equipment is about zero, the judging module considers that the equipment is out of water, and meanwhile, the state of the equipment is updated to be the water outlet state in the system memory. If the current water pressure of the equipment is a positive value, that is, the equipment is determined to be in a water entry state, the state of the equipment at the previous moment needs to be read, if the equipment is also in the water entry state at the previous moment, the interval of two water entry times is calculated, if the interval is greater than a certain threshold value (for example, the equipment is considered to be drowned in water for 60 seconds), that is, a drowning event occurs, and early warning information is sent out, which can be specifically referred to fig. 4.
Furthermore, the intelligent drowning management system further comprises a positioning module and a monitor, when the judging module judges that some equipment is drowned, the positioning module is triggered to extract the current picture, and possible drowning people in the picture are circled out through the trained AI model. In order to be more accurate, when registering equipment, a natatorium can correlate the gender and the age, once a drowner exists, the drowner is identified in a targeted manner through a pre-trained identification model, and the possible drowner is positioned in a picture;
for example: the drowning determination system detects: drowning occurs in the device 100011 (device identifier), the device 100011 registers as a child, the positioning module calls the monitoring picture at the same time, recognizes the model scanning picture, positions all images that the child may drown, sends an alarm and positions the most likely drowning person, which can be referred to fig. 5.
The early warning system is used for early warning and warning supervisors when drowning events occur. Preferably, the device information is bound with a supervisor, and the early warning system can directionally send out early warning to the outside, such as parents.
One specific application of this embodiment is: when a swimmer needs to swim, the swimmer carries a swimming cap or swimming goggles containing a water pressure collector, and registers equipment in a drowning judgment system before swimming, and can select to bind with the information of a monitoring person;
the signal transmitter can continuously transmit water pressure information at a certain frequency, the water pressure information comprises two parts (the identifier of the collector and the water pressure value), and the equipment identifier and the water pressure can be analyzed after the information is received by the drowning judgment system;
if the water pressure indicates water out, the device status is set to 0 (water out). If the water pressure indicates water entry, the state of the apparatus is set to 1 (water entry), and the present water entry time is recorded. The same equipment sends water pressure information next time, the same logic judges whether the equipment enters water or leaves water, if the equipment enters water, the time of entering water last time is compared, the time is less than a threshold value, the information (mainly not to modify the time of entering water last time) is ignored, if the time is greater than the threshold value, drowning is sent out, a positioning module is triggered to extract a monitoring picture, positioning is carried out through a model trained through deep learning, a drowner is circled out, and a drowning judging and positioning system is formed. In order to improve the positioning accuracy, when drowning occurs, the positioning module can quickly position the person who may drown in the swimming pool to rescue in combination with the character characteristics (such as the characters displayed by men, women and children) corresponding to the equipment.
It should be noted that the above device is also effective without the positioning module. Early warning can be completed. Early warning information lacks pertinence, and supervisors need more time to verify. And a positioning module is added, so that a supervisor can see the position of a drowner at the same time, and the condition can be verified and rescued more quickly.
