Detailed ways

Specific Embodiment 1. This embodiment will be described with reference to Figures 1 and 2. The electronic control device of the inflatable lifejacket includes a plug-in switch 1, a control unit 2, an electric and manual dual-purpose inflatable head 3 and a lifejacket light 4;

The control unit 2 is electrically connected to the plug-in switch 1, the electric and manual inflatable head 3 and the life jacket light 4 respectively;

The control unit 2 includes a single-chip microcomputer 2-10, a positioner 2-11, a pressure sensor 2-5, a battery 2-1, a first water immersion sensor 2-3, and a second water immersion sensor 2-1 integrated in the housing. 4. Magnetic charging contacts 2-7 and ten-pin connector 2-9; the single-chip computer 2-10 is connected with the positioner 2-11, the pressure sensor 2-5, the battery 2-1, and the first water immersion sensor respectively. 2-3. The second water immersion sensor 2-4, the magnetic charging contact 2-7 and the ten-pin connector 2-9 are electrically connected;

The housing is equipped with mounting ears 2-2 connected to the lifejacket body; as well as magnetic charging contacts 2-7, contacts 2-12 of the first water immersion sensor, and second water immersion sensor contacts provided on the housing. Contact two of the water immersion sensor 2-13, standby status indicator light 2-6 and charging status indicator light 2-8;

The standby status indicator light 2-6 and the charging status indicator light 2-8 are connected to the microcontroller 2-10.

In this embodiment, the model of the electric and manual dual-purpose inflating head is: 9002-3. Since it executes the inflation instructions of the controller, it also has a manual function.

The life jacket light 4 is used for calling for help at close range. Includes waterproof housing, high-brightness lamp, circuit board and related connection harness.

In this embodiment, the buckle is a must-install part of the lifejacket. When the lifejacket is put on, the buckle must be inserted. The system switch is installed in the buckle. When the buckle is inserted, the device automatically turns on and enters the standby state. When taking off the life jacket, pull out the buckle and the device will automatically shut down. This setting can avoid missing power on and save power to the maximum extent.

The plug-in switch includes a male end with a permanent magnet, a female end with a reed switch and a related wire harness connection device.

Specific Embodiment 2: This embodiment will be described with reference to Figures 1 to 4. This implementation is implemented using the electronic control device of the inflatable lifejacket described in Specific Embodiment 1. The control unit 2 is the core of the entire device. As shown in Figure 2, the control unit is mainly composed of the self-test of the life jacket controller, the inflation control part and the positioning part.

The self-test function mainly checks the reliability of the pressure sensors 2-5, the inflating head starting assembly, and the relevant wiring harness connections. The specific process is:

When the buckle is plugged in, the device automatically turns on and starts self-test, as shown in Figure 4. The microcontroller starts to initialize, and then starts the pressure sensor communication self-test. After the self-test, it starts the self-test of the electric manual dual-purpose inflatable head micro gas generator. After success, the green light will light up, indicating that the device is available; if there is a problem, the red light will light up to report a fault, indicating that the device is unavailable. When the device's standby indicator light turns green, the controller enters the sleep state (power saving mode) at the same time.

As shown in Figures 3 and 4, when the first water immersion sensor 2-3 and the second water immersion sensor 2-4 recognize water at the same time, the microcontroller 2-10 wakes up immediately and enters the water immersion alarm state. Pressure sensor 2-5 starts to read data, once every 10 milliseconds. When the pressure change is greater than 1KPa and 50 consecutive data are greater than 1KPa, the inflation start signal is immediately output to the electric manual dual-purpose inflation head.

The electric manual dual-purpose inflating head receives the start signal and immediately starts to generate gas, pushing the striker with the piston. The striker pierces the sealing diaphragm of the CO2 cylinder and releases the gas to inflate the life jacket.

The electric and manual dual-purpose inflatable head also has its own manual function. When other unexpected situations require manual inflation, you can use the manual function and pull the rope to inflate.

When the controller outputs the inflation start signal, it also outputs the lighting signal of the life jacket light, and at the same time starts to send the location information for help.

Life jacket lights are used to alert nearby rescuers that someone has fallen into the water. This allows rescuers to clearly observe the location of the person who fell into the water in dark weather or night.

In this embodiment, the control unit has its own positioning function and starts sending distress information when it falls into the water. It can be sent to the mobile phone in the form of a short message, indicating that someone fell into the water at X degrees east longitude and north latitude. It can also display the specific location of the person who fell into the water on the background display or on the mobile phone of the rescuer through the network.

The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Within the spirit and principle of the invention, any modifications, equivalent substitutions, improvements, etc. shall be included in the protection scope of the invention.
