Description

The utility model relates to the field of fire-fighting equipment and can be used as fire-fighting technical equipment when conducting fire reconnaissance in a smoky environment.

The technical result is an increase in reconnaissance efficiency due to partial restoration of visibility using a software-processed digital elevation model obtained from ultrasonic and infrared sensors.

The essence of the utility model: a sensing fire and rescue device consists of a fireproof housing attached to a fire helmet, which houses a microcontroller that processes signals from a phased ultrasonic array and IR sensors, temperature and humidity sensors. Based on the obtained digital heights of obstacle distances, at the software level, sensor data is compared, erroneous values of sensor heights are eliminated and the height map is simplified to highlight differences, visualize the outline of obstacles with a display of the distance to them. Visualization is carried out using a display or projecting an image onto the visor of a helmet or visor of a breathing apparatus. In addition to displaying the outline of the obstacle and the distance to it, the ambient temperature is displayed in the corners of the information display field, which helps to more quickly detect the source of the fire.

The closest in technical essence and achieved effect is a fire helmet [fire helmet: utility model patent No. 192698 U1 Russian Federation, IPC A62C 99/00. fireman's helmet: No. 2019103280: app. 07/21/2017: publ. 09.26.2019 / K.K. Barykin, R.I. Murtazin, D.D. Kislitsyn, A.I. Irkabaev; applicant: Federal State Budgetary Educational Institution of Higher Education "Ufa State Aviation Technical University". - EDN MTBTDR.], which is a fire helmet including a helmet with a visor and position sensors located on the helmet and protected by a fire-resistant casing. The device also contains a screen for displaying graphic information, a microprocessor for processing the received information, and position sensors are made of ultrasonic ones.

The disadvantage of this device design is the low probing ability of a single ultrasonic sensor and the lack of correlation data on ambient temperature and humidity for the operation of the ultrasonic sensor. The proposed solution's operational capabilities are limited to providing only the distance to the obstacle. Execution using only ultrasonic sensing technology limits the reliability of indicators in the aggressive environment of convective flow during a fire. The design of the helmet as a finished device in the helmet body limits the possibility of retrofitting existing firefighter helmets.

Similar in technical essence and achieved effect is an obstacle detection device [obstacle detection device: utility model patent No. 59208 U1 Russian Federation, IPC F21V 33/00. Obstacle detection device: No. 2006118249/22: application. 05/26/2006: publ. 12/10/2006 / S.O. Ershov, A.T. Bezuglov, V.N. Tishchenko; applicant State educational institution of higher professional education Baltic State Technical University "VOENMEH" named after. D.F. Ustinova (BSTU "VOENMEKH"). - EDN CUYURT.], which is a lighting lamp, an ultrasonic locator, an information processing unit and a signaling device, characterized in that the lighting lamp and the ultrasonic locator are combined in one device, and the directions of the central axes of the lighting lamp and the ultrasonic locator coincide.

The disadvantage of this device design is the low probing ability of the ultrasonic sensor and the absence of any information to increase the efficiency of reconnaissance except the sound signal.

The technical objective of the utility model is to increase the efficiency of reconnaissance by gas and smoke protection service units in a smoky environment.

The technical task of the utility model is achieved by the fact that a microcontroller that processes signals from the receivers of a phased ultrasonic array and an infrared sensor, a temperature sensor, based on the obtained values, creates a model of digital obstacle distance heights; at the software level, the sensor data is compared, the erroneous values of the sensor heights are eliminated and simplified height maps for highlighting differences, visualizing the outline of obstacles with displaying the distance to them. Visualization is carried out using a display or projecting an image onto the visor of a helmet or visor of a breathing apparatus. In addition to displaying the outline of the obstacle and the distance to it, the ambient temperature is displayed in the corners of the information display field, which helps to more quickly detect the source of the fire.

In fig. 1 and fig. Figure 2 shows a diagram of a probing fire and rescue device. The probing fire and rescue device consists of a fireproof housing with a folding projection part 1, a phased ultrasonic array consisting of receivers 2, an ultrasonic transmitter 3, a temperature sensor 4, a lidar sensor 5, a focal lens 6, a processor 7.

The general view of the probing fire and rescue device is clearly presented on a three-dimensional model. In fig. 3 is a general top view, FIG. 4 shows a general side view of the device, FIG. 3 General view from the front side.

The probing fire and rescue device operates as follows.

The ultrasonic transmitter 3 sends a signal, which, reflected from obstacles, returns and is processed by a phased ultrasonic array consisting of receivers 2, the obtained distance data of the digital elevation model (taking into account the value of the ambient temperature 4) to the obstacle is correlated with the distance readings received from the lidar sensor 5. Data pass through a filtration program for processing digital height models obtained from 2.5 sensors and are then displayed through a focal lens on the working surface of the visor or visor of a personal respiratory protection mask.

The use of a probing fire and rescue device allows you to:

partially restore visibility in smoky environments;

reduce the time required to search for victims and the source of a fire when conducting reconnaissance in a smoky environment;

increase the level of safety of the gas and smoke protection service units in the area of limited visibility.
