Position is simultaneously sent to information collection unit.Described information collection unit is by the position of the fire extinguisher main body tank body and nozzle exit area
Information, trainee position be converted to digital signal, and assign id information for the digital signal, generate the fire extinguisher master
The status information of body and the location information of trainee.Again by the first wireless transmit/receive units by the state of the fire extinguisher main body
The location information of information and trainee are sent.At this point, the state of the fire extinguisher main body is the fire extinguisher main body tank
The position of body and nozzle exit area, draw ring bolt are not extracted, press handle is not pressed.
Second wireless transmit/receive units receive the location information of the status information and trainee of the fire extinguisher main body.Data
Processing unit unpacks the status information of the fire extinguisher main body according to preset protocol, and identifies the ID of the fire extinguisher main body.
The state updating unit is corresponding to fire extinguisher main body described in the state information updating according to the fire extinguisher main body by unpacking
Virtual ejecta state, and preset virtual item and virtual flame are updated according to the virtual ejecta state synchronized.Enhancing
The information that real unit is exported according to the state updating unit will virtual ejecta state corresponding with the fire extinguisher main body,
Preset virtual item and virtual flame are superimposed upon on realistic space.It obtains the movement of trainee's hand-held fire-extinguisher but fire extinguisher does not have
There are ejecting extinguishing substance, fire always in the scene of burning.
When holding the movement of fire extinguisher main body in the trainee, and carrying out fire-extinguishing operations：
The position of fire extinguisher main body tank body and nozzle exit area described in the location tracking cell tracks, and by the fire extinguisher
The position of main body tank body and nozzle exit area are sent to information collection unit.The position of human body collecting unit acquires the trainee
Position and be sent to information collection unit.When the trainee pulls up draw ring bolt, the acquisition of draw ring plug-in switch amount is single
Member collects draw ring bolt and is unplugged, then the information that draw ring bolt is pulled up to state is sent to information collection unit.It is described by
When instruction personnel press press handle, press handle analog acquisition unit acquires the degree of pressing of the press handle, and press handle is pressed
The information of lower degree is sent to information collection unit.Described information collection unit is by the position of the fire extinguisher main body tank body and spray
The mouth information of position, the position of trainee, draw ring bolt pulls up state and the degree of pressing of press handle is converted to digital signal, and
Assign id information for the digital signal, then by the first wireless transmit/receive units by the status information of the fire extinguisher main body and
The location information of trainee is sent.At this point, the state of the fire extinguisher main body is the position of the fire extinguisher main body tank body
It is pressed with nozzle exit area, the extraction of draw ring bolt, press handle.
Second wireless transmit/receive units receive the location information of the status information and trainee of the fire extinguisher main body.Data
Processing unit unpacks the status information of the fire extinguisher main body according to preset protocol, and identifies the ID of the fire extinguisher main body.
The state updating unit is corresponding to fire extinguisher main body described in the state information updating according to the fire extinguisher main body by unpacking
Virtual ejecta state, and preset virtual item and virtual flame are updated according to the virtual ejecta state synchronized.Enhancing
The information that real unit is exported according to the state updating unit will virtual ejecta state corresponding with the fire extinguisher main body,
Preset virtual item and virtual flame are superimposed upon on realistic space.Obtain trainee's hand-held fire-extinguisher ejecting extinguishing substance with
And the scene of respective change occurs for flame and stage property.
Further, when trainee is less than given threshold with a distance from virtual fire, vital values can be reduced constantly, until being
0, the trainee exits training after being 0；When there is multi-person synergy training, state update module will be distinguished by the ID of fire extinguisher
Update.
Embodiment 3
Present embodiment discloses the teaching scene of above-mentioned fire extinguisher teaching of use system, the scene is as follows：
After trainee dresses AR glasses, trainee can penetrate the change in location that AR glasses are immediately seen fire extinguisher main body
And state change；When carrying out fire extinguishing training, trainee first has to pull out the draw ring bolt in fire extinguisher main body, when scene is reappeared
After module receives the data of draw ring plug-in switch amount collecting unit acquisition, fire extinguisher can be switched to sprayable virtual extinguishing material
State, then trainee press the press handle in fire extinguisher main body again, adopted when scene rendering module receives press handle analog quantity
After the data for collecting unit acquisition, the initial velocity for the virtual extinguishing material injection of extent control that can press according to trainee and greatly
It is small, and be superimposed upon in current scene, and the respective change that the virtual flame of real-time update and stage property occur.Trainee can be after
Continuous mobile fire extinguisher, repeated presses operation, until putting out burning things which may cause a fire disaster, or fire extinguishing failure.
