5results about How to "Protect life" patented technology

This invention discloses a vehicle control method, computer device, and storage medium based on the detection of entities left behind in the vehicle. The invention includes steps such as obtaining a detection image of the vehicle's interior space while the driver is away from the vehicle, identifying entities left behind in the detection image, and controlling vehicle components to perform protective actions against the entities when the type information of the left-behind entities meets preset conditions. By analyzing the type information of entities left behind in the vehicle's interior space while the driver is away, and controlling vehicle components to perform protective actions against the entities when the type information meets preset conditions, this invention can automatically protect entities left behind even if the driver negligently fails to remove them from the vehicle. This protects the life or property of the left-behind entities without requiring the driver to return to the vehicle, providing convenience for the driver. This invention has wide applications in the field of automotive technology.

The present application relates to a kind of reentry atmosphere spacecraft safety landing system, comprising: spacecraft on-board system software is configured to detect the power output of spacecraft flight power system, and when detecting no power output, first signal is continuously sent to landing intelligent system;Landing intelligent system is connected with the spacecraft on-board system software communication, and is configured to perform the following actions: receive first signal and time, when the duration of no power output reaches first duration, enter emergency rescue mode, send rescue information and spacecraft positioning information, and when the duration of no power output reaches second duration, start physical self-help system, second duration is greater than first duration;And ground emergency command control center is configured to perform the following actions: after receiving rescue signal and the positioning information of spacecraft, start unmanned aerial vehicle system to find spacecraft according to positioning information.The safe recovery of spacecraft can be realized by the system.

The invention provides a gas detection sound-light alarm device and an alarm state identification method, and relates to the technical field of industrial gas detection.The device comprises a detector host module, a safety barrier module and a sensor sensing component which are arranged in a detector explosion-proof cavity, and a sound-light alarm module assembled outside the detector explosion-proof cavity; the detector host module is electrically connected with the sensor sensing part and the safety barrier module, and the safety barrier module is electrically connected with the sound-light alarm module through a two-wire system. And when the detected gas concentration information reaches a preset alarm threshold value, or the sensor sensing part has a fault and the detection is out of range, the detector host module synchronously realizes power supply on-off and parameter configuration signal transmission to the sound-light alarm module through the safety barrier module. The device has the advantages of low wiring and intrinsic safety cost, compact size, safe and reliable driving scheme and the like, can be widely applied to gas detector alarm devices, and guarantees the safety of personnel life and production equipment.
