Specific embodiment
Explanation of nouns：
Radar terminal：Finger operates in the program in the equipment such as computer, signal and cartographic information that the program will be gathered
Connect, and simultaneous display is to user, allows users to judge the geographical position residing for signal target.
In order that the technical problems to be solved by the invention, technical scheme and beneficial effect become more apparent.Hereinafter tie
The present invention will be described in detail by step to close accompanying drawing.
As shown in Figures 2 to 4, the invention provides a kind of mapping module software organization method of radar terminal, the method
Comprise the steps of：
Step 1：Radar terminal and mapping module are run on same machine.Radar terminal can lead to map load-on module
Cross local loopback address transmission data.
Step 2：Map load-on module is in the state that waits for the arrival of news all the time, until receiving the map making from radar terminal
Request.
The library file of the map datum that map datum provider can provide, calls its interface function or direct during map making
The map of a width bitmap format is drawn out by reading data therein.The function of map load-on module is individually to load these storehouses
File, draws out required map.
As can be seen that how separate map load-on module carries out accurately and not influenceing performance with radar terminal
Communication is key content of the invention.In the present invention, the message transmission between radar terminal and map load-on module employs socket
The mode of word communication, i.e., realize the data transfer between process by local loopback address.Communication mould is separately added into two modules
Block simultaneously arranges port numbers, and data frame transfer is carried out by udp protocol.Its advantage is：Sent by local loopback address
Data frame method applicability it is high, its transmission is completed by internal memory, minimum on the influence of the operational efficiency of radar terminal
And will not have any consumption to network.
Step 3：When radar terminal starts or its map state changes, correlation can be sent by mode described in step 1
Parameter gives map load-on module, subsequently into etc. state to be feedback；
When radar terminal starts or operator carries out needing the operation for redrawing map, can be automatically by needed for map making
Parameter (geographical location information, range, center position, map elements) is stored in data frame, and the communication said by step 1
Mode is sent to map load-on module.After being sent, terminal can immediately enter the state of waiting for the arrival of news, until receiving map loading
The feedback message that the mapping that module is sent is finished.
Step 4：After receiving the message from radar terminal, map load-on module reads parameter therein immediately, according to ginseng
Number draws out map and is stored in clipbook, after the completion of the message completed to terminal feedback by way of described in step 1；
The carrier of map datum may have dynamic link library, packaged class file, executable program or simple
The diversified forms such as data file, but map load-on module reads and the mode of map making only has two kinds anyway.It is a kind of
It is to call the interface appointed with carrier to obtain map datum, another kind is by reading file or similar mode from containing
Map datum is directly read in the file of map datum.Concrete implementation method is determined by the provider of map datum.
Between radar terminal and map load-on module view data is transmitted using the built-in clipbook function of system.In system
The clipbook put is one section of memory headroom that can continuously, with storage information size change, and is total to by different application programs
Enjoy.The all built-in function of clipbook of most systems.No matter radar terminal needs to be run under which type of operating system, only
Will the system there is graphical interfaces, the function of clipbook is can be transferred through to realize this demand.
It is a width bitmap images that map load-on module needs the content of transmission, and other local transmission modes are required for a position
Figure is stored in character string by byte and carried out data transmission again, is read out from character string again after reception.And clipbook then can be with
Directly deposited for different application programs and read bitmap data, efficiency is higher than other transmission means.
Clipbook is shared by local application, in order to prevent being subject to other programs or keyboard defeated during process communication
The influence for entering, clipbook after map is stored in clipbook by map load-on module, can be set to read-only status and sent complete
Message to radar terminal, completed until step 5 reads bitmap.
Step 5：Radar terminal reads bitmap after receiving message, and realizes loading the correlation function of map.
After receiving the message of map load-on module transmission, you can read from clipbook and map datum and drawn
Out.The lock-out state of clipbook is released after the completion of reading.It is stored in bitmap extremely short to the time between taking out, does not interfere with substantially
To the operation of other programs.
This method realizes the modularization of map load-on module first, is then communicated with UDP Socket and is mutually tied with clipbook
The mode of conjunction realizes the local communication of map load-on module and radar terminal, so that both are both separate two
Module, flexibly can rapidly carry out data exchange again, reach the modular purpose of map function.Two kinds of present invention selection enter
The mode communicated between journey is that multi-platform multisystem is general, and compatibility is strong and is not easily susceptible to the unusual condition of other programs generation
The influence of (such as internal memory spilling).By test, data transfer is spent in whole process time is few, with modularization before simultaneously
Will not change significantly.The present invention is transformed suitable for the terminal of active service radar, is also applied for the Terminal Design of New Type Radar.
