Fig. 3 is at the interior three layers of event trace figure of building.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is specifically described in detail.
As shown in Figure 1, the locating and displaying device of event trace in buildings, main structural components comprises display, processor, storer, baroceptor, GPS locator, gyroscope, passometer and input end, display, storer, baroceptor, GPS locator, gyroscope, passometer and input end are all connected with processor, indoor map imports intelligent terminal by input end and stores in memory, baroceptor, GPS locator, the corresponding data of acquisition is transferred to processor by gyroscope and passometer in real time, and record in memory and store, show in the display after the treated device process of data.
Aforementioned display device can be TFT LCDs, UFB LCDs, STN screen etc.; Processor can be the programmable processor such as arm processor, intel processor; Memory storage capabilities is not less than 10M; Baroceptor can be digital gas pressure sensor; Input end can be mechanical keyboard or tactile keyboard.
Adopt the locating and displaying device of event trace in above-mentioned buildings to carry out the locating and displaying of event trace in buildings, when location starts, import the indoor map information of this buildings in a device; Current location atmospheric pressure P to be positioned is obtained, record initial position point coordinate (X by baroceptor
0, Y
0) and the direction angle of initial position point; Processor calculates buildings basic unit sea level elevation A by formula 1
0with real-time sea level elevation A
1,
formula 1
P
0for standard atmospheric pressure 1013.25hPa, when P is buildings basic unit air pressure, calculates and obtain buildings basic unit sea level elevation A
0, when P is the air pressure of device, calculate the real-time sea level elevation A of obtaining means
1
Processor utilizes formula 2, draws real-time story height F,
F=(A
1-A
0)/H+1 formula 2
In formula, H is the actual floor height of buildings; Result of calculation rounds up, round numbers.
Processor goes out each foot path of intelligent terminal possessor according to following formulae discovery, obtains the track set in conduct process, and by the track display of walking in indoor map;
Direction1 is the angle that previous step is corresponding, direction2 is the angle that a rear step is corresponding, when direction1 is more than or equal to 0 compared with the angle θ that direction2 changes, namely determine that pedestrian there occurs and turn left or craspedodrome action, a rear step trajectory coordinates is:
X
i=X
i-1-dis*scale*sin(pi/2 * angle-θ); Formula 3
Y
i=Y
i-1-dis*scale*cos(pi/2 * angle-θ); Formula 4
When direction1 is less than 0 compared with the angle θ that direction2 changes, namely determine that pedestrian there occurs turning action, for turning right, a rear step trajectory coordinates is:
X
i=X
i-1+ dis*scale*sin(pi/2 * angle-θ); Formula 5
Y
i=Y
i-1+ dis*scale*cos(pi/2 * angle-θ); Formula 6
In formula, azimuth angle theta is by gyroscope Real-time Obtaining, and distance dis is obtained by passometer, and scale is the engineer's scale of indoor map, and i is step number, and i>0, X, Y are position coordinates, angle=0,1,2,3; 0 is north, and 1 is east, and 2 is south, and 3 is west;
The position coordinates point of a step after calculating successively according to above formula, until indoor positioning terminates, location point (x
i, y
i) set be event trace, display on a display screen.
North latitude 32.0938 °, east longitude 118.7894 °, Sectors of Gulou Dis trict, Nanjing central authorities square, road uses the locating and displaying device of event trace in buildings, carries out the actual location test of event trace in buildings.This square totally 17 floors is high, when location starts, imports the indoor map vector of this square 1-17 layer in locating and displaying device.Locating and displaying device possessor carries out activity at Stall, and now, baroceptor obtains the atmospheric pressure P=1014.1hPa of Stall, record initial position point coordinate (X
0, Y
0) and the direction angle of initial position point.Processor calculates one deck A in real time
0=-7.07m.Because this building one deck is basic unit, therefore, A
1=A
0, real-time story height F=1, namely this staff of system identification is positioned at the Stall on this square, and the indoor map vector recalling Stall immediately positions.Processor calculates each foot path of locating and displaying device possessor successively, obtains the track set in conduct process, and by the track display of walking in indoor map; As shown in Figure 2, dotted line is the event trace of staff.
Three layers, Zai Shangdaogai square, obtained the atmospheric pressure P=1012.8hPa of 3rd floors by baroceptor, processor calculates A
1=3.74m.The actual floor height 5.2m in this square, processor calculates real-time story height F=3, and namely this staff of system identification is positioned at 3rd floors of this square, and the indoor map vector recalling 3rd floors immediately positions.Processor calculates position of each step of staff successively, and as shown in Figure 3, dotted line is this staff at the event trace of 3rd floors.
