Description
Technical field
The present invention relates to the technical fields such as Signal coding, signal transacting, calibration array organization, computer graphics, utilize the infrared signal generating means after coding to form honeycomb array in particular to a kind of, thus realize the location position techniques and methods of position resolution power about a socket bore.
Background technology
Intelligent terminal provides positioning service have many methods, now more general method is that satnav and AGPS method are to determine the current location of holder terminal.But above technology, due to positioning error and environment for use restriction, can not use easily in (location within 10 meters of scopes) and indoor environment (gps signal generally cannot receive in indoor) more among a small circle.But, how in less scope (such as in 10 meters), in indoor environment, provide enough accurate positioning service to be expand and one of the key link going deep into IT application.Infrared generator is formed honey-comb shape array, and different Signal codings is adopted to different socket bore.Like this, when intelligent terminal for reception is to signal, by steps such as signal transacting, decoding, geography information mappings, just can determine current position.
Summary of the invention
The present invention will relate generally to three partial contents:
1, infrared signal generating means and calibration array organization mode;
This device comprises with lower component and function.1. infrared transmitter and interlock circuit, for generation of infrared signal; 2. MCU or CPU, for the realization of the functions such as Signal coding process and online programming; 3. this device should have applicable infrared emitting power, thus realizes good positioning function.
According to the characteristic (emissive power, frequency, coded system etc.) of infrared generator, device is set in the center of regular hexagon (community).Device in adjacent regular hexagon adopts different transmission frequencies.The community that next with current regular hexagon frequency is identical can be determined like this, after any regular hexagon chain moves i community, be rotated counterclockwise 60 degree in a mobile j community.Like this, the neighbor cell with different frequency forms a district group, and group small area, district quantity is: N=i
2+ ij+j
2.As accompanying drawing 1 and accompanying drawing 2.
2, infrared receiver and functional description
Infrared receiver generally should possess following key element and function, the infrared receiver ability of certain frequency and interlock circuit, certain signal handling capacity, wireless network access and communication capacity, geographic information processing and display capabilities.General intelligent terminal has possessed or will possess above-mentioned functions after doing simple extension.
When receiving trap is in the array of the infrared generator composition in work, the peak signal received can be decoded and this information is delivered to geographic information server by wireless network, relevant geography information and positioning result just can return in receiving trap by server, and receiving trap shows after doing suitably process.As accompanying drawing 3.
3, the implementation method of electronic chart:
Electronic chart is for representing the positional information of geography information and holder terminal.Electronic chart can be that the contracting ratio of actual scene reproduces, namely according to fixed object position and size in scene, and the corresponding figure of scaled foundation or image; Also can according to the error size of actual location, the details in the scene that can not accurately locate is given up, and forms brief and concise electronic chart; Further, in conjunction with feature and the pros and cons of computer graphic image treatment technology, that design is simplified, that expression layers is clearly demarcated electronic chart, thus the schematic map that realization more effectively uses on intelligent terminal.
Accompanying drawing explanation
The district group schematic diagram that Fig. 1 infrared generator of the present invention is formed
In the honeycomb array that Fig. 2 infrared generator of the present invention is formed, homogeneous frequency adjacent area looks for method
The component drawings mainly comprised in Fig. 3 device of the present invention
Note: due to limited conditions, content shown in legend, only plays signal effect, the corresponding functional structure in kind of non-critical.
Embodiment
Concrete implementation content comprises, geographic information server and geography, locator data tissue; In place to be positioned, use infrared generator to mark different geographic position; Wireless network access point is affixed one's name in the middle part of place; On infrared receiver, (on intelligent terminal) writes the display of software simulating geography information and positioning function.
Geographic information server and geography, locator data tissue
The hardware device of geographic information server because of locator data number, the terminal quantity of simultaneously serving etc. and determine its performance, and and then select the type that is applicable to.After type is determined, by runtime database service software on it.Geographical, locator data will press certain organize in a database.Locator data mainly refers to described by the honeycomb array that is made up of infrared generator and the positional information determined, geography information and infrared generator must be mapped the position in honeycomb array in geographic information server.Utilize this corresponding relation set up just can realize positioning function.
Infrared generator is disposed in place to be positioned
In principle, infrared generator should be arranged in orthohexagonal mid point, but should suit measures to local conditions in actual deployment process, and according to place actual conditions, the conditions such as signal intensity arrange the position of infrared generator flexibly.After arranging, the coded message that infrared generator need be sent associates to the corresponding geographic information data in geographic information database.
Wireless network access point is affixed one's name in the middle part of place
The laying of wireless network access point should be taken into account that co-channel interference, terminal use the factors such as density.When co-channel interference is large, reduce the emissive power of access point, increase access point and lay quantity; When terminal uses density height, then increase access point and lay quantity.
Intelligent terminal is write the display of software simulating geography information and positioning function
Intelligent terminal should have infrared receiver component and interlock circuit; Wireless network access ability should be had, the database that can be wireless on geographic information server, thus obtain the information needed.In addition, also display element should be had, button or touch control component, processor, the elements such as storer.
This software functionally comprises infrared receiver and process, position enquiring and display, point-to-point transmission shortest path calculate and show, the best access path of multi-point calculates and show.
When holder terminal is arranged in the array of infrared generator composition and uses corresponding geographic information services software, the signal that this terminal meeting real-time reception infrared generator sends, after doing signal transacting, and being sent to geographic information server by position encoded by wireless network, server returns corresponding geography information and positioning result after doing respective handling.
When inputting destination key message, returning the geography information such as shortest path from current location to destination and locator data after terminal device inquiry geographic information server and being presented in terminal.
The best access path of multi-point calculates and display.After terminal user inputs multiple destinations key message, the best access order and the path of these points can be inquired about or calculate to terminal device.
