Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0017] Currently, with technological advancements, more and more high-altitude recreational projects and high-altitude exploration missions are emerging. For safety reasons, parachutes are typically used to protect users or objects during these activities. However, current high-altitude safety parachutes only consider the scenario of a smooth descent upon deployment, neglecting the possibility of landing on water. When landing on water, the surface cannot stably support the user or object, thus compromising safety.

[0018] To address one or more of the above-mentioned problems, the water-triggering circuit of this application includes a first power input port, a second power input port, a first output port, a second output port, a first detection copper pillar, a second detection copper pillar, a first resistor, a second resistor, a first transistor, a second transistor, and an NMOS transistor. The first power input port and the first detection copper pillar are connected to a first node, which is connected to the first transistor, the second transistor, and the first output port. The second power input port is connected to the first resistor, the second resistor, and the NMOS transistor. The first transistor is connected to the second detection copper pillar, the first node, and the first resistor. The second transistor is connected to the first node, the first transistor, the first resistor, the second resistor, and the NMOS transistor. The NMOS transistor is also connected to the second output port, the first resistor, and the second resistor. The first output port and the second output port are connected to an external load. When the water-triggering circuit is triggered by water, the external load is controlled to operate accordingly through the first output port and the second output port.

[0019] The water-activated automatic triggering circuit described in the preferred embodiment of the present invention, such as... Figure 1 As shown, the water-triggering circuit includes a first power input port H1H1, a second power input port H4H4, a first output port H5H5, a second output port H6H6, a first detection copper pillar H2H2, a second detection copper pillar H3H3, a first resistor R24R24, a second resistor R25R25, a first transistor Q2Q2, a second transistor Q4Q4, and an NMOS transistor Q3Q3; Wherein, the first power input port H1 and the first detection copper pillar H2 are connected to the first node, and the first node is connected to the first transistor, the second transistor Q4 and the first output port H5 respectively; the second power input port H4 is connected to the first resistor R24, the second resistor R25 and the NMOS transistor Q3 respectively; the first transistor is connected to the second detection copper pillar H3, the first node and the first resistor R24 ​​respectively, and the second transistor Q4 is connected to the first node, the first transistor, the first resistor R24, the second resistor R25 and the NMOS transistor Q3 respectively; the NMOS transistor Q3 is also connected to the second output port H6, the first resistor R24 ​​and the second resistor R25; The first output port H5 and the second output port H6 are connected to an external load. When the automatic water-triggering circuit is triggered by water, the external load is controlled to operate accordingly through the first output port H5 and the second output port H6.

[0020] Furthermore, the second power input port H4 is connected to the first resistor R24 ​​at the second node and to the second resistor R25 at the third node. The second node is connected to the third node, and the third node is connected to the NMOS transistor Q3. The second transistor Q4, the first transistor, and the first resistor R24 ​​are connected to the fourth node, and the second transistor Q4, the second resistor R25, and the NMOS transistor Q3 are connected to the fifth node.

[0021] In the water-triggering circuit, the base of the first transistor Q2 is connected to the second detection copper pillar H3, the collector of the first transistor Q2 is connected to the first node, and the emitter of the first transistor Q2 is connected to the fourth node; the base of the second transistor Q4 is connected to the fourth node, the collector of the second transistor Q4 is connected to the connection node between the first node and the first output port H5, and the emitter of the second transistor Q4 is connected to the fifth node; the gate of the NMOS transistor Q3 is connected to the fifth node, the drain of the NMOS transistor Q3 is connected to the second output port H6, and the source of the NMOS transistor Q3 is connected to the third node.

[0022] Furthermore, in this invention, one end of the third node is grounded.

[0023] In this invention, the automatic water-triggering circuit will not output the corresponding negative power supply at the first output port H5 and the second output port H6 when it is not exposed to water under normal conditions. That is, the external load connected to the first output port H5 and the second output port H6 will not be triggered. Specifically, when the automatic water-triggering circuit is not exposed to water under normal conditions, the first detection copper pillar H2 and the second detection copper pillar H3 are not conducting, the base of the first transistor Q2 is floating, so the first transistor Q2 is cut off, the base of the second transistor Q4 is at a low level, and the corresponding Vbe is not greater than the conduction voltage, that is, the voltage between the base and the emitter is not greater than the conduction voltage. Therefore, the third transistor Q4 is cut off, and the gate of the corresponding NMOS transistor Q4 is at a low level, and the Vgs voltage, that is, the voltage between the gate and the source of the NMOS transistor Q4, is not greater than the threshold voltage. Therefore, the NMOS transistor Q4 is in the off state and will not output the negative power supply.

[0024] Furthermore, the first output port H5 and the second output port H6 are connected to the external load; The external load is a device that is pre-configured according to requirements.

[0025] Specifically, in this invention, the external load is a device that the user pre-sets according to their needs.

[0026] In this invention, when the first detection copper pillar H2 and the second detection copper pillar H3 in the water-triggering circuit encounter water, the first detection copper pillar H2 and the second detection copper pillar H3 are turned on, the base of the corresponding first transistor Q2 is at a high level, and the corresponding Vbe is greater than the conduction voltage, so the first transistor Q2 is turned on. When the first transistor Q2 is turned on, the base of the second transistor Q4 is set to a high level, so the second transistor Q4 is turned on. When the second transistor Q4 is turned on, the gate of the NMOS transistor Q3 is set to a high level, so the NMOS transistor Q3 is turned on. Then the corresponding first output port and second output port output the negative terminal of the power supply, and the external load will be triggered accordingly.

[0027] The automatic water-triggering circuit of this invention includes a first power input port H1, a second power input port H4, a first output port H5, a second output port H6, a first detection copper pillar H2, a second detection copper pillar H3, a first resistor R24, a second resistor R25, a first transistor Q2, a second transistor Q4, and an NMOS transistor Q3. The first power input port H1 and the first detection copper pillar H2 are connected to a first node, which is connected to the first transistor, the second transistor Q4, and the first output port H5. The second power input port H4 is connected to the first resistor R24, the second resistor R25, and the NMOS transistor Q3. The first transistor is connected to the second detection copper pillar H3, the first node, and the first resistor R24. The second transistor Q4 is connected to the first node, the first transistor, the first resistor R24, the second resistor R25, and the NMOS transistor Q3. The NMOS transistor Q3 is also connected to the second output port H6, the first resistor R24, and the second resistor R25. The first output port H5 and the second output port H6 are connected to an external load. When the automatic water-triggering circuit is triggered by water, the external load is controlled to operate accordingly through the first output port H5 and the second output port H6. This invention, through the automatic water-triggering circuit, enables the user or object to safely land on water using a parachute. The circuit detects the current environment and controls the external load accordingly to achieve safe rescue of the user or object, thereby ensuring the safety of the parachute landing.

[0028] Furthermore, such as Figure 2 As shown, based on the above-mentioned water-triggering automatic system circuit, the present invention also provides a water-triggering automatic system, wherein the water-triggering automatic system includes a water-triggering automatic circuit module 21 and a load module 22; The water-triggering circuit module 21 is used to implement the function of the water-triggering circuit, and after the water-triggering circuit is automatically triggered, it controls the first output port H5 and the second output port H6 to output the negative power supply. The external load module 22 is used to trigger the external load correspondingly after receiving the negative power output from the first output port H5 and the second output port H6. Specifically, in this invention, the water-triggering system includes a corresponding water-triggering circuit module and an external load module. The water-triggering circuit module detects whether the device is currently in water, and when it is in water, it triggers the external load module to achieve safety protection.

[0029] Furthermore, the external load includes one or more of the following: an airbag system, an automatic parachute detachment device, a positioning beacon, and an inflatable life-saving device. The airbag system includes an inflation device and a corresponding airbag. Upon triggering, the inflation device inflates the airbag to prevent the user or item from falling into the water, thus providing safety protection. The automatic parachute detachment device, upon triggering, separates the parachute from the person or item carrying it, preventing the parachute from being dragged by the water current and causing danger. The positioning beacon, upon triggering, acquires the current location information and sends it to a pre-set device. The inflatable life-saving device includes an inflation device and a life-saving device. In one embodiment of the invention, the inflation device is a lifebuoy. Upon triggering, the life-saving device is inflated by the inflation device, thus providing safety protection.

[0030] Furthermore, such as Figure 3 As shown, based on the above-described automatic parachute release circuit, the present invention also provides a method for protecting a parachute from water exposure, the method specifically including: Step S100: When the water-triggering circuit is triggered, the water-triggering circuit outputs the negative terminal of the power supply to trigger the external load. Step S200: Run the external load.

[0031] Furthermore, the automatic water-triggering circuit is triggered, specifically including: When the first detection copper pillar H2 and the second detection copper pillar H3 are shorted, the first detection copper pillar H2 and the second detection copper pillar H3 are turned on, correspondingly turning on the first transistor; Based on the conducting first transistor Q2, the second transistor Q4 is turned on; Based on the conducting second transistor Q4, the NMOS transistor Q3 is turned on, and the water-triggering circuit is triggered.

[0032] Specifically, in this invention, when the water-triggering circuit is placed in water, the first detection copper pillar H2 and the second detection copper pillar H3 are shorted, thereby turning on the first transistor Q2, the second transistor Q4, and the NMOS transistor Q4, thus triggering the water-triggering circuit. Furthermore, the operation of the external load specifically includes: When the external load is an airbag system, the airbag system's inflation device is activated to inflate the airbag; When the external load is an automatic parachute release device, the automatic parachute release device is activated to release the parachute; When the external load is a positioning beacon and an inflatable life-saving device, the positioning beacon is controlled to send positioning information to the pre-set device, and the inflatable life-saving device is operated.

[0033] Specifically, in this invention, the external load is a pre-set device or equipment for protection. Further, the external equipment may be an airbag system, an automatic parachute release device, a positioning beacon, and an inflatable life-saving device.

[0034] Furthermore, based on the above-mentioned water-triggering circuit, system, and parachute water protection method, the present invention also provides a parachute, which includes a water-triggering circuit.
