Another object of the present invention is to provide a kind of Intellgence navigation device for carrier booster, is equiped with a dynamic display in the base, and cooperates the high speed graphic display interface so that map and carrier place coordinate position to be provided, so that observe.

For reaching aforementioned projects, the present invention is made up of a navigation device for carrier booster and base station apparatus, this base station system by a global positioning system antenna, a hi-Fix receive with reference to device, a central controlling computer, a large-scale projector equipment, a high speed graphic man-machine interface, a dynamic display, answers the inquiry machine and an antenna is formed; And should central authorities' controlling computer include a Control Software, a numerical digit map and a memory;

This navigation device for carrier booster by an electronic type gyroscope, an odometer, a global location sensor, an antenna, answer inquiry machine, a small-sized graphical human-machine and a map display and form; Wherein, this register control comprises a Control Software and a numerical digit electronic chart;

This is answered the inquiry machine and is formed by a bus-bar, an address decoding circuit, a first in first out controller, an impact damper, a photo-coupler, a phase-locked loop, a modulation circuit and tandem register control arranged side by side; Mainly be to utilize the global location sensor, cooperate the numerical digit electronic chart, answer inquiry machine and register control and make location signal error correction with the base, can reach 3-5 meter accurate localization degree, and in position control device, install an electronic type gyroscope additional and can effectively solve the city high building and stop the problem of locating signal, and answer the inquiry machine in the neutral time of making error correction by one, traffic information, meteorological data are broadcasted on the carrier at whole networking, make it to obtain correctly and fast information, simultaneously by the usefulness of a large-scale projector equipment as the monitoring of carrier.

Below by specific embodiment, conjunction with figs. is done a detailed description to the present invention.

Description of drawings:

Fig. 1 is a base station block schematic diagram of the present invention.

Fig. 2 is a carrier device block schematic diagram of the present invention.

Fig. 3 is that the present invention answers inquiry machine block hardware diagram.

Fig. 4-1,4-2 are that the present invention answers inquiry machine circuit figure.

The present invention utilizes X.25 networking specification, reaches CSMA(Carrier Sense Maltiple Access csma to answer the inquiry machine) structure, increase the capacity of channel in the mode of time-frequency division.Because the position sensor satellite still is US military control at present, in order to separate military and civilian different on purposes, US military is designed CA-Code use among the people is provided, just SA(Selec-tive Availability selects availability), yet its degree of accuracy but significantly reduces, for improving degree of accuracy, the present invention adopts the mode of error correction, consult Fig. 1, shown in 2: promptly receive with reference to device 16(Receive Referncer at base station installing hi-Fix) receive via global positioning system antenna 17, can utilize long-time accumulation and calculate own exact position (less than 5 meters), when the antenna 21 of carrier receives the positioning system satellite signal, can receive same group of satellite signals with base station by answering inquiry machine 22; Wherein, this is answered inquiry machine 22 and is not sent out signal at ordinary times, only after accepting instruction, just begin to send signal, and this function is the Control Software 13 control settings by the central controlling computer of this base station, compare with the reference position and calculate error and demarcate on the central controlling computer numerical digit ground of this base station Figure 14 in the position that this Control Software 13 receives itself, and with the carrier data storage in the central controlling computer memory 15 of this base station, and by a large-scale projector equipment 20 and via a high speed graphic man-machine interface 18 and dynamic display 19 signal of demarcating is manifested respectively, and cooperate and to answer inquiry machine 12 error correction values is sent on the carrier via antenna 11, can obtain the high precision position information of 3-5 meter.

If when in the city, using, location sensing satellite is influenced by covering of building or buildings, sometimes can't finish the minimum standard of three satellite dual space location, for overcoming installing electronic type gyroscope 28 and odometer 29 on this difficulty carrier of the present invention, the position sensor Control Software 23 of register control receives the navigation data that position sensor transmits via antenna 21 on the carrier when normal operation, again with answer the error amount that inquiry machine 22 is sent here, retrieve simultaneously numerical digit electronically Figure 24 with the location position of carrier own on the numerical digit map, by a small-sized graphical human-machine 27 with the position display of demarcating on a map display 26.Suppose that the location signal is blocked, the sensor Control Software 23 of carrier monitors out that global location sensor 25 can't correctly be located or signal quality is too poor, immediately with last point positioning system navigation data, direction and distance with gyroscope 28 and odometer 29 are extrapolated present longitude and latitude, just can separate the bad problem of decision bit signal; Again, the inquiry machine of answering 12,22 of this base station and carrier can all give encipherment and make it receive and dispatch signal, with confidentiality and the security that communication is provided via Control Software 13,23 setting codes.

The present invention of being shown in Figure 3 answers and askes the device block hardware diagram.As shown in the figure: when antenna send signal to come in (modulation input end 39), through optically coupled circuit 31, pin phase place with phase-locked loop 32, convert data arranged side by side to and send into bus-bar 34, receive by the position sensor Control Software again via a tandem, converter 33 arranged side by side.And modulation output terminal 40 is also delivered to modulation circuit 35 by tandem converter 33 arranged side by side and signal is exported.The signal that reception is come in is delivered to the external world by address decoding circuit 36 via a first in first out controller 37 and an impact damper 38 after software processes.

Another characteristics of the present invention, consult shown in Figure 1: base station installing one location receives with reference to device 16, and not only carrier carries out error correction, and base itself have maneuverability at any time mobile carrier and base relative bearing, distance and reach the time.

Consult Fig. 4, for answering, the present invention askes the device circuit diagram, as shown in the figure: the upper left corner of drawing is bus-bar 34, and be address decoding circuit 36, first in first out register control 37 and impact damper 38 from left to right in regular turn, the below then is positioned at the tandem register control 33 arranged side by side in centre position from left to right for photo-coupler 31, phase-locked loop 32, modulation circuit 35 and.Because the present invention cooperates the numerical digit electronic chart, answer inquiry machine and register control and make location signal error correction with the base, and can reach 3-5 meter accurate localization degree, and in position control device, install an electronic type gyroscope additional, thereby can solve the city high building effectively and stop the problem of locating signal, and answer the inquiry machine by one and making the time dead of error correction, with traffic information, meteorological data is broadcasted on the carrier at whole networking, make it to obtain correctly and fast information, simultaneously by a large-scale projector equipment with monitoring as carrier, thereby have the effect of carrier control robotization.
