Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further 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 present application and are not intended to limit the present application.
Referring to fig. 1, in an embodiment of the present application, there is provided an emergency opening method of a door of a sealed cabin, including:
s1, monitoring whether a user pushes a bulkhead inside the sealed cabin, wherein the bulkhead comprises a door and a window of the sealed cabin, and the user is positioned in the sealed cabin;
and S2, if the user is monitored to push the wall of the sealed cabin, starting an escape program to open the door of the sealed cabin.
In the embodiment, the bulkhead in the sealed cabin is uniformly provided with the medium sensor array, wherein the bulkhead comprises transparent positions such as doors and windows of the sealed cabin, and the medium sensor array can clearly display capacitance change generated by partial contact of the sensing surface by materials such as fingers, water drops and conductive rubber. And the control system of the closed cabin monitors whether the user pushes the wall of the closed cabin in real time through capacitance change generated by the medium sensor array on the wall of the inner cabin of the closed cabin. Specifically, the control system collects the touch area of the user limb and the bulkhead in real time through the medium sensor array, and as the skin of the human limb is a soft curved surface, when the user pushes the bulkhead with different force paths, the larger the force path is, the larger the contact area of the skin of the user limb and the bulkhead surface is, namely when the user pushes the bulkhead, the direct proportion relationship between the touch area and the pushing force is realized. Therefore, the control system calculates the pushing force of the user limb acting on the bulkhead according to the proportional relation between the touch area between the bulkheads of the user limb and the pushing force. The control system calls a preset force threshold value and judges whether the current pushing force is larger than the force threshold value. If the pushing force is less than the force threshold, the user may unintentionally touch the bulkhead (e.g., inadvertently touch the bulkhead when the user turns inside the cabin) and not encounter an emergency, and thus the control system determines that the user is not pushing the bulkhead inside the enclosure. If the pushing force is greater than the force threshold value, the behavior mode that the user hurriedly and vigorously beats and pushes the wall of the sealed cabin to escape from the sealed cabin as soon as possible when encountering an emergency is met, and therefore the control system judges that the user is pushing the wall of the sealed cabin. At this time, the control system starts an escape program of the sealed cabin, controls the sealed cabin to execute corresponding necessary actions for opening the cabin door (for example, if the sealed cabin is a hyperbaric oxygen cabin, the hyperbaric oxygen cabin is required to execute a decompression-door opening action, so that healing above atmospheric pressure can be stopped and the cabin door can be opened), so that the cabin door can be opened in time, and a user in the sealed cabin can escape from the inner space of the sealed cabin in time. In the embodiment, the control system can identify the behavior mode of the user in the sealed cabin when the user encounters an emergency and is in a panic state, and the cabin door is opened in time for the user to easily escape from the sealed cabin, so that the potential safety hazard that the user cannot correctly start the escape degree due to panic when the user uses the sealed cabin alone to encounter a critical situation and is trapped in the sealed cabin is avoided, and the safety performance and the intelligent degree of the sealed cabin during use are greatly improved.
Further, a media sensor array is disposed on a side of the bulkhead facing the space inside the enclosure, and the step of monitoring whether the user pushes the bulkhead inside the enclosure includes:
s101, acquiring the touch area of the user limb and the bulkhead in real time through the medium sensor array;
s102, calculating and obtaining the pushing force of the user limb acting on the cabin wall according to the touch area;
s103, judging whether the pushing force is greater than a force threshold value;
s104, if the pushing force is larger than a force threshold value, judging that the user pushes the bulkhead in the closed cabin;
and S105, if the pushing force is smaller than the force threshold, judging that the user does not push the cabin wall in the closed cabin.
In this embodiment, a medium sensor array is uniformly disposed on one side of the cabin wall facing the internal space of the closed cabin, and the control system scans a sensing surface (i.e., the surface of the internal cavity of the closed cabin) formed by the medium sensor array to determine all touch points in the medium sensor array that are in contact with the user's limb to generate capacitance change. And the control system counts the total number of all touch points to obtain the touch area of the sensing surface formed by the user limb and the medium sensor array, namely the cabin wall. Due to the characteristics of the skin of the limbs of the human body, the larger the force of the limbs of the user acting on the cabin wall is, the larger the touch area between the limbs of the user and the cabin wall is, namely, the positive correlation relationship is formed between the touch area and the squeezing force. And (3) the developer constructs a calculation formula according to the positive correlation between the touch area and the extrusion force, wherein the calculation formula represents the positive correlation function relationship between the touch area and the extrusion force, and the calculation formula is recorded into the control system. And the control system substitutes the touch area acquired at the current time into a calculation formula to calculate the pushing force of the user limb acting on the cabin wall. The control system calls a preset force threshold value and judges whether the current pushing force is larger than the force threshold value. If the pushing force is less than the force threshold, the user may unintentionally touch the bulkhead (e.g., inadvertently touch the bulkhead when the user turns inside the cabin) and not encounter an emergency, and thus the control system determines that the user is not pushing the bulkhead inside the enclosure. If the pushing force is greater than the force threshold value, the behavior mode that the user hurriedly and vigorously beats and pushes the wall of the sealed cabin to escape from the sealed cabin as soon as possible when encountering an emergency is met, and therefore the control system judges that the user is pushing the wall of the sealed cabin. In this embodiment, the control system obtains the contact area between the user limb and the bulkhead through the medium sensor array, and then calculates the force of the user limb pushing the bulkhead, so as to avoid the interference influence of the air pressure in the closed cabin. Taking the hyperbaric oxygen chamber as an example, the pressure in the hyperbaric oxygen chamber is much higher than the outside pressure, so the chamber wall can bear huge pressure under the influence of the difference between the inside pressure and the outside pressure of the chamber body. If the pressure acting on the surface of the bulkhead is directly sensed by a pressure sensor or the like, the interference influence of the pressure caused by the difference between the internal pressure and the external pressure cannot be accurately eliminated. The control system of the embodiment indirectly measures and calculates the force of pushing the cabin wall by the limbs of the user through the medium sensor array, the work of the medium sensor array is not influenced by the difference between the internal air pressure and the external air pressure, the identification degree is clear, and the measurement accuracy is high.
Further, the step of acquiring a touch area of a user limb and the bulkhead in real time through the media sensor array includes:
s1011, scanning the sensing surface formed by the medium sensor array to obtain all touch points in the medium sensor array, which are in contact with the user limb;
and S1012, counting the total number of the touch points to obtain the touch area.
In this embodiment, the control system scans the sensing surface formed by the media sensor array to obtain all touch points in the media sensor that are in contact with the user's limb, and a surface formed by the touch points represents the touch surface between the user's limb and the sensing surface (i.e., the surface of the cabin wall). And the control system counts all the touch points to obtain the total number of the touch points, and the total number represents the touch area between the user body and the cabin wall when the user body pushes the cabin wall. Preferably, the control system can identify not only the continuous touch of the user limb on the sensing surface but also the change of the touch area, the area of the outline of the touch surface and the change of the area of the outline by continuously and rapidly scanning. The control system connects the touch points at the outermost periphery, so that the outer contour of the touch surface when the user limb pushes the bulkhead can be outlined, the area of the outer contour also represents the force of the user limb pushing the bulkhead, namely the larger the area of the outer contour is, the larger the pushing force is, and the two touch points are also in positive correlation. Therefore, the control system can also compare the extrusion force corresponding to the area of the outer contour with another set force threshold value, and when the extrusion force corresponding to the area of the outer contour is greater than the other set force threshold value, the cabin door is opened for the user to escape.
Further, the step of scanning the sensing surface formed by the medium sensor array to obtain all touch points in the medium sensor array, which are in contact with the user's limb, includes:
s10111, scanning the sensing surface to obtain a plurality of initial sites causing the capacitance of the dielectric sensor array to change;
s10112, determining a site concentrated region according to the distribution position of each initial site, wherein the site concentrated region represents the maximum region of the user palm touching the induction surface;
s10113, removing the initial points, of which the distance from the center of the point concentration region is greater than a preset distance, from the initial points to obtain the touch points, wherein the preset distance corresponds to the distance between the two farthest end points on the palm of the human body.
In this embodiment, the user limb is a palm of the user (that is, the limb part of the bulkhead pushed by the user is the palm), and the control system scans the sensing surface formed by the medium sensor array to obtain a plurality of initial sites on the sensing surface, which cause capacitance change of the medium sensor array (the capacitance change of the medium sensor array can be caused by contact between materials such as human limbs, water drops, and conductive rubber and the like and the medium sensor array). And the control system determines the initial sites which are adjacently distributed between every two initial sites as being positioned in the same area according to the distribution position of each initial site, so that a plurality of initial concentrated areas are generated. Then, screening out one initial concentration region containing the initial sites with the maximum number of initial sites as a site concentration region from each initial concentration region, wherein the site concentration region represents the maximum region of the touch between the palm of the user and the sensing surface. The control system eliminates initial sites with the distance from the center of the site concentration area larger than a preset distance from each initial site to obtain each touch site corresponding to the palm of the user; wherein the preset distance is the distance between the two farthest end points on the palm of the human body. In this embodiment, the control system determines the site concentration region and performs site screening according to the preset distance, so that other interferences that can cause capacitance change of the media sensor array, such as water droplets, can be effectively avoided (for example, water droplets are attached to the bulkhead, if the region to which the water droplets are attached is not excluded, the touch sites acquired each time also include sites of the region to which the water droplets are located, so that the touch area is increased, after the regions to which a plurality of water droplets are attached are accumulated, a mechanism for opening the cabin door urgently is triggered under the condition that a user does not push the bulkhead, and the possibility of erroneous judgment exists), and the accuracy of measuring and calculating the touch area is improved.
Further, the step of determining a site concentration region according to the distribution position of each of the initial sites includes:
s101121, determining the initial points which are distributed adjacently between every two points as being located in the same region, and generating a plurality of initial concentrated regions;
s101122, screening out one initial concentrated region with the largest number of initial sites from each initial concentrated region as the site concentrated region.
In this embodiment, the initial points that are distributed adjacently between two sensing surfaces are located in the same region, for example, the palm of the user pushes the bulkhead, and the initial points corresponding to the region where the skin of a single finger is in close contact with the sensing surface of the bulkhead should be distributed adjacently between two sensing surfaces; and if there is a certain distance between the two initial sites, the two initial sites should belong to different concentration areas, such as an initial site a on the concentration area corresponding to the skin of the middle finger, and an initial site B on the concentration area corresponding to the skin of the thumb, and there is a certain distance between the initial site a and the initial site B, which are not distributed adjacently. The control system determines the initial points which are distributed adjacently between every two points to be positioned in the same area, and generates a plurality of initial concentrated areas. Then, one initial concentration region containing the largest number of initial sites is selected from the initial concentration regions as a site concentration region. For example, when a user pushes the bulkhead with a palm, even if the area of the bulkhead where the water droplets are attached is identified as the initial concentrated area, the contact area between the palm and the sensing surface is inevitably much larger than the area corresponding to the water droplets when the user pushes the bulkhead with a large force. Therefore, the control system selects the initial concentrated region with the largest area as the locus concentrated region, so that the touch locus corresponding to the whole palm of the user can be determined according to the locus concentrated region, the actual situation is met, and the touch area corresponding to the palm of the user can be accurately positioned.
Further, the step of calculating the pushing force of the user limb acting on the bulkhead according to the touch area includes:
s1021, acquiring age information, gender information and volume information of the user;
s1022, matching corresponding force coefficients according to the age information, the gender information and the volume information;
and S1023, calculating the pushing force according to the touch area and the force coefficient.
In this embodiment, when the user uses the sealed cabin, the personal information (including age information, sex information, and volume information, wherein the volume information is estimated according to the height and the circumference of the user) of the user is input into the control system for storage. And after the control system collects the touch area of the limbs and the bulkhead of the user, matching the corresponding force coefficient according to the age information, the gender information and the volume information of the user. The control system is internally stored with an age, gender, volume and force coefficient mapping table, and the age, gender, volume and force coefficient mapping table comprises a plurality of groups of age, gender, volume and force coefficients in one-to-one correspondence. The human skin of different ages, sexes, volumes (i.e. height, three-dimensional) is different in relaxation degree, for example, the sex is male, the age of user A is 20 years old, the age of user B is 50 years old, user A and user B all push the bulkhead with the same dynamics, because the skin relaxation degree of both is different, the area of touch of user B and response face can be greater than the area of touch of user A and response face. Therefore, users of different ages and sexes need to correspond to different force coefficients, the pushing force obtained by the control system after calculation according to the touch area and the force coefficients can be matched with the users, the accuracy is better, and the reliability of the control system is improved.
Further, a media sensor array is disposed on a side of the bulkhead facing the space inside the enclosure, and the step of monitoring whether the user pushes the bulkhead inside the enclosure includes:
s106, acquiring the touch frequency of the user limb and the bulkhead in real time through the medium sensor array;
s107, judging whether the touch frequency is greater than a frequency threshold value;
s108, if the touch frequency is larger than a frequency threshold value, judging that the user pushes the cabin wall in the closed cabin;
and S109, if the touch frequency is smaller than a frequency threshold, judging that the user does not push the cabin wall in the closed cabin.
In this embodiment, a medium sensor array is disposed on a side of the cabin wall of the closed cabin facing the internal space of the closed cabin, and the control system acquires, in real time, a frequency of a touch between a user limb and the cabin wall through the medium sensor array, where the frequency of the touch represents a number of times that the user limb and the cabin wall touch within a preset time period (for example, a number of times that the user limb and the cabin wall touch within 5S). And then the control system calls a preset frequency threshold, compares the current touch frequency with the frequency threshold and judges the size relationship between the current touch frequency and the frequency threshold. If the touch frequency is less than the frequency threshold value, the situation that the user is unconsciously contacted with the bulkhead with a high probability (for example, the user accidentally touches the bulkhead when turning over in the cabin body) does not belong to an emergency situation, and therefore the control system judges that the user does not push the bulkhead. If the touch frequency is greater than the frequency threshold value, the behavior mode that the user needs to escape by quickly slapping doors and windows and bulkheads of the closed cabin in a confused state when encountering an emergency is met, so that the control system judges that the user pushes the bulkheads in the closed cabin, further executes the next action and opens the bulkheads for the user to escape.

In the emergency opening device for the door of the closed cabin provided by the embodiment, the control system monitors whether a user pushes the cabin wall inside the closed cabin in real time, wherein the cabin wall comprises a door and a window of the closed cabin, and the user is located in the closed cabin. And if the control system monitors that the user pushes the cabin wall of the closed cabin, an escape program is started to open the cabin door of the closed cabin for the user to escape.

Therefore, when the control system identifies that the user pushes the cabin wall, the cabin door is opened in time for the user to escape from the sealed cabin easily, the potential safety hazard that the user cannot start the escape degree correctly due to confusion when the user uses the sealed cabin alone to meet emergency is avoided, and the safety performance and the intelligent degree of the sealed cabin in use are greatly improved.
