[0025] like Figure 1 As shown in the figure, this embodiment proposes a dangerous water area monitoring device, including a human body sensor, an image acquisition device, a power supply circuit, a power processing circuit, a loudspeaker circuit, and a main control circuit; the power supply circuit is connected to the power processing circuit and the image acquisition device, and the power processing circuit is connected to the loudspeaker circuit, the main control circuit, and the human body sensor.

[0026] The device can realize multiple early warning functions: first, for pedestrians on the shore, the human body sensor will immediately issue a voice warning and red and blue warning flashes, and the LED screen will scroll the warning message; second, the image captured by the image collector is uploaded to the cloud platform through the main control circuit, and the anti-drowning intelligent early warning system is used to divide the monitoring area into two regions. The area within 1 meter of the river is divided into region 1, and the area below the water is divided into region 2. Region 1 and region 2 are divided into dangerous areas. In this dangerous area, the intelligent monitoring and intelligent recognition of human body movement detection function is adopted. When someone enters region 1 despite the first sound and light warning, the camera will start the human body detection AI algorithm, and if the real-time video detects that a human body has been in region 1 for more than 10 seconds, it is judged that the person has entered the dangerous area, and real-time detection and warning reminders will be given. The relevant visual recognition software has a relatively mature solution on the market that can be directly applied. Through the anti-drowning intelligent early warning system, the camera cloud platform realizes the effect of 'one picture, one network, and one domain', and realizes intelligent monitoring, intelligent recognition, and real-time warning in key water areas; third, the camera shouting function is installed, which can directly shout to the scene by the office manager, drive the people to get into the water, and send real-time warning to the surrounding personnel to realize risk control and timely disposal of the drowning event.

Early detection and early treatment can be achieved, thereby reducing the harm caused by drowning.

[0028] Further, the main control circuit includes a control chip and a wireless communication chip connected therewith, and a flow card slot is arranged on the main control circuit. The control chip is supplied with a stable 3.8V voltage by a TD1583 step-down circuit, and a more stable 4G main control module L610-CN is used. The main control module L610-CN is connected with a S336 satellite positioning module, a TPA3110 power amplifier module, a human body sensing module, and a flash module in the circuit, and can stably transmit data and instructions. At the same time, the main control module L610-CN is connected with each part in the circuit, detects the state of each part of the circuit, and processes the information obtained by the circuit, and is responsible for controlling the operation of the circuit system. The main control circuit inserts a 4G flow card, and uses the online function to smoothly transmit function instructions and data codes between the device and the cloud platform.

[0029] Specifically, the wireless communication chip adopts an Air724UG master control module, which has the functions of two-way intercom, flexible configuration of multiple playing modes, and data synchronization with the cloud platform.

[0030] Optionally, the master control circuit further comprises a single-chip microcomputer control circuit, which adopts a higher-performance QFN-128P single-chip microcomputer master control module, and is connected with the one-key intercom master control module Air724UG and the paging microphone master control module Air724UG through a RY3430 step-down circuit to provide a stable 3.3V and 1.0V working voltage, control the command transceiving control between them, detect the information obtained by the processing signals of each part, and be responsible for the operation of the control command system.

[0031] Further, the power supply circuit comprises a solar panel, a charging circuit and a storage battery, the solar panel is connected with the charging circuit, and the charging circuit is connected with the storage battery. The charging circuit is configured as a CN3767 circuit, which cooperates with a small amount of peripheral devices to perform PWM step-down on the power input by the solar panel. The CN3767 has two modes of constant current charging and overcharging, after the battery voltage reaches a certain level, the CN3767 enters the constant current charging stage, at this time the charging current is set through an external resistor, to ensure that the battery is charged with a stable current, as the battery voltage rises, the CN3767 gradually reduces the charging current, when the battery voltage reaches the set overcharge voltage 12.6V, it enters the overcharge stage. In this stage, the charging current will gradually decrease until it is reduced to 16% of the constant current charging current, at this time the charging is considered to be completed, and the battery enters the floating charging state. By using more stable and accurate components, the charging is more stable, and a PMOS tube is used instead of a traditional diode to reduce the heat generated during the charging process.

Properly adjusting the device parameters of the circuit makes the entire circuit more stable, the deviation is reduced, and a voltage of 3.8V can be stably output.

[0034] The second voltage reduction circuit: the voltage supplied by the lithium battery is processed by the 78L05S voltage reduction circuit and stably output to a 5V voltage output, which is supplied to the TPA3110 power amplifier module in the rear end to supply power and maintain its playing work.

[0035] The third voltage reduction circuit: a more stable XL1509 voltage reduction circuit is adopted to reduce the 12V voltage provided by the 12V power supply, and the voltage is reduced to 3.8V and supplied to the one-key intercom master control module Air724UG and the paging microphone master control module Air724UG in the rear-end circuit, to provide a stable voltage supply and make it have a stable working environment.

Precise calculation and use of higher precision electronic devices enable the RY3430 voltage reduction circuit to stably output 3.3V and 1.0V two voltages to provide stable power supply for the load in the rear stage, so that it can work stably.

[0037] The voltage stabilizing circuit: the 3.8V voltage processed by the voltage reducing circuit of TD1583 is processed by the voltage stabilizing circuit of SSP7603P33 again, is stabilized to 3.3V, and outputs 3.3V to the S336 satellite positioning module to work.
