Technical Field
The invention belongs to the field of life-saving articles, and relates to an automatic detonation type life-saving air cushion based on millimeter wave radar detection.
Background
Along with the increase of the survival pressure of the modern society, the number of the people who jump the building and live gently is increased, meanwhile, the high-rise building erected in the forest also has the risk of high-altitude falling, the frequency of high-altitude falling events under the combined action of multiple factors is gradually increased, and the high-altitude falling rescue method has higher requirements. The lifesaving air cushion is a common high-altitude rescue device at present, and is suitable for ground rescue of people in danger in high-rise buildings and people who jump building and are light. Although there have been many successful rescue cases for life saving air cushions, there are some limitations. The existing rescue air cushion has longer inflation time due to larger size, and accidents happen already when the existing rescue air cushion is not unfolded frequently in emergency. Meanwhile, when the judgment of the falling place has a large error, the rescue of the people in danger cannot be effectively carried out, and even the rescue personnel can be injured.
Disclosure of Invention
In view of the above, the present invention provides an automatic detonation type rescue air cushion based on millimeter wave radar detection.
In order to achieve the purpose, the invention provides the following technical scheme:
an automatic detonation type lifesaving air cushion based on millimeter wave radar detection comprises a millimeter wave radar, an air bag gas generator, a safety air bag and an air cushion outer fabric;
the millimeter wave radar is in signal connection with the gas generator of the air bag;
the safety airbag is in signal connection with the airbag gas generator;
the safety airbag is externally coated with an air cushion outer fabric;
the millimeter wave radar is fixedly connected with the outer fabric of the air cushion, so that when the outer fabric of the air cushion is in a folded state, the millimeter wave radar is positioned above the outer fabric of the air cushion, the connecting position of the radar and the air cushion is positioned on the bottom surface of the air cushion, part of the air cushion at the connecting position is positioned above after being folded, and the millimeter wave radar naturally moves to the lower part of the air cushion after being unfolded, so that secondary damage to falling personnel caused by hard objects is avoided;
a falling target is found by transmitting and receiving electromagnetic wave signals through a millimeter wave radar, and the position and the speed of the target are measured; when the millimeter wave radar detects that the target is in a free falling body state, an electric signal is generated and transmitted to the gas generator, and the purpose of detonation is achieved.
Optionally, the airbag is an airbag array formed by a plurality of point-explosion airbags.
The invention has the beneficial effects that:
the air cushion can be inflated to achieve the rescue condition in a short time, and high-altitude falling personnel and building-jumping suicide personnel can rescue in time in emergency. The preparation time required by rescue is shortened, the rescue success rate of the building-jumping light life personnel and the people in danger is greatly enhanced, and the rescue pressure of the firefighters is reduced.
Further, if the target is not in a falling state within a certain time, the airbag cannot explode to inflate the airbag, so that the traditional airbag is prevented from being continuously inflated and replenished.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Firstly, the life-saving air cushion based on millimeter wave radar detection adopts a detection mode that a falling target is found by transmitting and receiving electromagnetic wave signals through the millimeter wave radar, and parameters such as the position, the speed and the like of the target are measured. When the millimeter wave radar detects that the parameter of the target reaches a certain threshold value, an electric signal is generated and transmitted to the gas generator, and the purpose of detonation is achieved.
② the novel fire-fighting air cushion comprises an inner layer explosion air bag, an outer layer air cushion and a millimeter wave radar. The air cushion structure is characterized in that a millimeter wave radar and an air bag array consisting of a plurality of explosion air bags are arranged in a typical lifesaving air cushion, the millimeter wave radar is a sensing device and a signal transmitting device, and the air bag array is used as an internal filler of the lifesaving air cushion. The action principle is that falling personnel are induced by the millimeter wave radar, an electric signal is sent out to explode all internal air bags, and the external air cushion is rapidly unfolded.
Connecting relation and functional action among all parts:
the inner air bag gas generator is fixedly connected with the outer air cushion fabric and used for fixing the relative positions of the air bag and the air cushion so as to ensure that the air cushion can be filled to an expected shape after all the air bags are unfolded; the line connection between the gas generator and the millimeter wave radar is used for transmitting an explosion signal sent by the radar so that the gas generator works normally; the fixed connection between the millimeter wave radar and the surface of the air cushion ensures that the radar is positioned above the air cushion in a folded state and naturally moves to the lower part of the air cushion after being unfolded, so that the secondary injury of falling personnel caused by the hard object is avoided;
in the above structure, some of the following alternatives may be made:
firstly, the millimeter wave radar can be replaced by other similar detective devices as long as the detection and signal transmission functions of the millimeter wave radar are met; secondly, the lattice arrangement of the airbag position arrangement can be replaced, and only the unfolding state of the air cushion is required to be met;
the cross section of the invention is shown in figure 1, wherein 1 is millimeter wave radar, 2 is airbag gas generator, 3 is safety airbag, and 4 is outer fabric of air cushion.
The working principle of the invention is shown in figure 2, the structure comprises three parts, namely an induction radar, a gas generator, an air bag and fabric outside an air cushion, and the main functional characteristics of the invention are that falling personnel above a fire-fighting air cushion are automatically detected and an explosion signal is sent out, the fire-fighting air cushion is rapidly inflated in a short time, and the falling of the falling personnel is buffered to achieve the rescue purpose.
Further, the connection between the components. The induction radar is fixed on the outer side of the air cushion fabric, the air cushion is positioned above the air cushion before being unfolded, and the induction radar moves to the lower part of the air cushion after being unfolded; the detonation signal generated by the induction radar is transmitted to the gas generator through a lead; the gas generator is an inflation source of the air bag, and is uniformly arranged on the inner side of the fire-fighting air cushion in a lattice mode, and the relative positions of the rest air cushions before and after the explosion do not change.
The usage effect of the invention is shown in fig. 3 and 4. The fire-fighting air cushion in a folded state is placed near an estimated falling point of falling personnel, and the millimeter wave radar is placed above the air cushion to detect the falling personnel. When falling personnel appear in the radar sensing area, the radar transmits a signal to the gas generator to ensure that the air bag in the fire-fighting air cushion is exploded, so that the air cushion is rapidly unfolded to accept the falling personnel above.
Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
