Embodiment

As shown in Figure 1, a kind of communication means of location, comprises three base stations, the first base station 2, base station 1, second, the 3rd base station 3; First base station 2, base station 1, second and the 3rd base station 3 form a detectable plane space, in detectable plane space 8, there is multiple moving target perceptron, as the first moving target perceptron 4, second moving target perceptron 5, n-th moving target perceptron 6; Each moving target perceptron destination determined is this purpose relevant to the internal information of moving target perceptron record, as air ticket has boarding gate; When a person in the plane obtains air ticket, by application moving target perceptron, undertaken navigating to boarding gate by moving target perceptron.

Therefore, whole navigation, will by following process implementation, the coding of Network Capture moving target perceptron is passed through in first base station 2, base station 1, second, the 3rd base station 3, one of them base station timing of first base station 2, base station 1, second, the 3rd base station 3 sends wireless synchronization information to the moving target perceptron obtaining coding, replys response message after the first moving target perceptron 4, second moving target perceptron 5 or the n-th moving target perceptron 6 receive synchronizing information with audio frequency to the first base station 2, base station 1, second, the 3rd base station 3; The first moving target perceptron 4, second moving target perceptron 5 or the n-th moving target perceptron 6 position is determined in first base station 2, base station 1, second, the 3rd base station 3, and being sent their coordinate and navigation information to the first moving target perceptron 4, second moving target perceptron 5 or the n-th moving target perceptron 6 by wireless network, the first moving target perceptron 4, second moving target perceptron 5 or the n-th moving target perceptron 6 move to destination according to navigation direction information 9.

Because audio frequency and radio propagation velocity ratio comparatively want slow many, signal transacting is easy, can obtain the degree of precision being better than 5cm, accurate positioning.

As shown in Figure 2, in order to reach above-mentioned effect, moving target perceptron comprises wireless receiver 202, processor 201, memory 205, sound transmitter 204, orientation detection circuit 206, display 203 and battery 207, wireless receiver 202, processor 201, memory 205, wireless receiver 202, processor 201, sound transmitter 204, orientation detection circuit 206, display 203 and battery 207 are fixed in housing 208, wireless receiver 202, sound transmitter 204, orientation detection circuit 206, display 203 is electrically connected with processor 201 respectively, processor 201 controls wireless receiver 202 and receives wireless signal, processor 201 controls sound transmitter 204 and sends acoustic signals, the azimuth information determination coordinate that processor 201 receives according to wireless receiver 202, by transferring the cartographic information that memory 205 stores, changing coordinates is shown, obtain azimuth information by orientation detection circuit 206 to show simultaneously, conjunction orientation detection circuit 206 information and cartographic information lead eventually, go to destination under making not need inquiry route situation.

As shown in Figure 3, each base station comprises radio transmitters 301, base station processor 302, base station memory 303, acoustic receiver 304, power supply 305, clock circuit 306 and frequency select circuit 307, radio transmitters 301, base station processor 302, base station memory 303, acoustic receiver 304, power supply 305, clock circuit 306 and frequency select circuit 307 to be fixed in the spacious housing of screen, radio transmitters 301, base station memory 303, acoustic receiver 304, power supply 305, clock circuit 306 and frequency select circuit 307 to be electrically connected with base station processor 302 respectively by interface, each base station is electrically connected to each other.

One of them base station is dominant base, and dominant base processor obtains synchronous clock by clock circuit, and makes standard to moving target perceptron transmission signal with this clock signal.

As shown in Figure 4, when moving target perceptron receives clock signal t0, moving target perceptron sends audio signal to space, and moving target perceptron sends the frequency of audio signal to base station and the time is determined by the coding of himself; Coding gives frequency and the start-up time of moving target perceptron, can work to make multiple moving target perceptron simultaneously, base station receives the signal of multiple moving target perceptron by timesharing, frequency division, after base station receives signal, its distance is measured according to time t0, t1, t2, t3, t0 is wireless reference time, moving target perceptron is when receiving t0, send audio signal or time delay immediately and send audio signal, the moving target perceptron frequency of operation audio frequency time of the difference of t0 and t1 to be audio frequency be f1; The moving target perceptron frequency of operation audio frequency time of the difference of t0 and t2 to be audio frequency be f2; The moving target perceptron frequency of operation audio frequency time of the difference of t0 and t3 to be audio frequency be f3; The distance signal received with three points calculates its locus.

Only so adopt, different frequency is to have the work of more moving target perceptron with space at one time, can not form co-channel interference between them simultaneously.
