Detailed Description
The present invention will be described in detail with reference to the following examples.
Example 1
AR glasses capable of displaying fire conditions comprise a positioning module, a display module and a communication module; the positioning module is used for determining the current position of the AR glasses, and displaying the channel structure of the building where the AR glasses are located and the position of the equipment in the channel structure according to the current position. The building channel structure is displayed in a combined stereoscopic and planar manner, for example, a small stereoscopic view of the whole building channel structure can be displayed, the current position in the stereoscopic view is marked, and a channel route map of the current position and direction, namely a planar map, is displayed at the main viewing angle. The plan view is equivalent to a map and a map of a building, and is correspondingly displayed in real time according to the position and the orientation. To implement the corresponding display, the AR glasses further include a general-purpose memory module, a gyroscope, an inertial navigation device, and the like, which are well known in the industry. The communication module of the AR glasses is wirelessly connected with monitoring equipment in a building to obtain a plurality of sensing data, and the display module superposes the sensing data and sensing positions corresponding to the data in the building channel structure for display.
Wherein, the supervisory equipment is a plurality of sensors of arranging inside the building, and AR equipment is direct with a plurality of sensor wireless connection. The monitoring device is a module of the building central control device for collecting or storing data of each sensor, and the AR device is connected with the module so as to obtain a plurality of sensing data. And displaying the sensing data obtained at each position in the channel, which is updated in real time, at each position or near the current position in the display module. Based on this sensing data, the person of wearing can be more convenient learn position on fire, the fire gas development condition to and the dangerous degree of oneself position, the route of withdrawing etc..
The recommended evacuation route may also be displayed superimposed in the display module according to the building passage structure and the fire.
Wherein the communication module comprises a 5G communication module, which can perform device direct connection (D2D) with the monitoring device having the 5G communication module. In case of fire or serious disaster, the conventional wireless communication method is likely to be damaged, and communication cannot be completed. A feature of 5G communications is that device-to-device (D2D) communications may be implemented between 5G devices without going through a base station or other distributed device. The device provides great convenience for rescue and escape when disasters occur.
In addition, the communication module is also used for receiving specific information, such as help-seeking information, and the help-seeking information comprises position information.
Example 2
A fire condition display system comprising the AR device of embodiment 1 and further comprising a plurality of sensors having 5G communication modules, each sensor being wirelessly connected to the AR device, e.g., 5G-based device direct connection (D2D) via the communication modules. Wherein a plurality of sensors are arranged at a plurality of locations within the building to detect fire in real time. The sensors include various sensors such as smoke sensor and temperature sensor, and each sensor obtains corresponding sensing data such as smoke concentration value and temperature value at each position. And each sensing data is transmitted to the AR equipment through a wireless network, and a display module of the AR equipment superposes the sensing data of each position to the architectural passageway structure chart for display.
In addition, there may be multiple AR devices of embodiment 1 within the system. The AR devices are also connected through a 5G wireless network, for example, the positions of other AR devices are also displayed in the display module of each AR device, and voice communication can be carried out between the AR devices through the communication module. The display system also includes a server and a system display. The server is in wireless connection with the AR equipment and the sensor and is also connected with the system display. In the system display, the location of the AR device may be displayed, as well as the sensed data for each location.
When a fire occurs in a building, internal personnel can know implementation conditions of all channels including personnel density, smoke, temperature values and the like through AR equipment, so that an optimal evacuation route can be selected, and the system server can also perform overall evacuation deployment to organize personnel to evacuate in order. If the channel has an emergency such as open circuit, and the like, and the AR devices and the server can accurately know the field situation in the modes of personnel flow direction, voice communication and the like under the condition of not using corresponding sensor data to react, the server can control the open circuit position to display a corresponding identifier, and the personnel are prevented from continuously moving in the open circuit direction.
Example 3
The AR equipment described in embodiment 1 is used for fire search and rescue. The search and rescue personnel wear the AR equipment and search trapped personnel; when receiving help-seeking information sent by the trapped people, analyzing the position information contained in the help-seeking information; then, the position information is displayed in an overlapping mode; search and rescue personnel comprehensively judge and determine a rescue route according to the building channel structure, the sensing data and the position information, and organize rescue.
When a fire happens, because inside personnel lack lifesaving equipment, often can be stranded inside the building and can't flee, need lifesaving personnel to get into from the outside and search for and rescue the stranded personnel this moment, timely and safe arrival personnel stranded position is the key of rescue, outside rescue personnel can in time know the inside fire of building through AR equipment, know the real-time developments of each route, thereby select the best route of getting into, reach the position of stranded personnel with the fastest speed, rescue. Meanwhile, the condition inside the building is predicted according to the sensing data, and the rescue workers are prevented from being trapped in the fire scene.
Example 4
People always cause panic in case of emergency, and fire exercises performed at ordinary times have poor portability to people participating in exercises due to no actual fire, and the exercise effect is usually not ideal. Based on this, a fire drill method is provided, in which the persons participating in the fire drill wear the AR device described in embodiment 1, and perform the fire drill by using the display system described in embodiment 2.
Firstly, simulating a fire scene by a system, and designing parameters such as a fire occurrence place, a fire diffusion rate and the like; then, controlling a monitoring system to obtain a plurality of simulated sensing data in real time according to the designed parameters; displaying the simulated sensing data in the AR equipment, and overlapping and displaying simulated fire scenes including fire behavior, smoke images and the like; and finally, the personnel participating in the fire drill select a reasonable escape route for evacuation according to the display in the AR equipment.
Through the fire prevention exercise with the real picture, the psychological quality of the personnel facing sudden fire can be exercised, and when the fire happens, confusion is avoided, and the personnel can evacuate quickly.
