Embodiment Construction

[0007] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0008] see figure 1 , the method for processing track information by wire control software of the present invention comprises the steps of: first receiving track information; then, judging whether the track information exists, if the track information does not exist, then setting up a two-way linked list to store the track information, establishing The track information includes allocating a certain length of continuous space in the dynamic storage space of the memory, let X= * malloc(unsigned int size); then, let X->next=Null, X->pre=Null, tail=head that is Complete the establishment of the empty linked list.

[0009] If the track information exists, then judge whether the track information is new track information, if it is new track in...

Abstract

The invention provides a display control software track information processing method. The implementation principle of the method is that the fact that a new chain table is created for storing track information through creating operation of the chain table; a new track is established through inserting operation of the chain table; a target track is located through checking operation of the chain table; updating of the track is achieved through inserting operation and deleting operation of the chain table; revocation of the track is achieved through chain table deleting operation; and internal storage releasing is achieved through chain table releasing operation. The problem that large continuous-internal-storage space needs to be occupied for radar display control software track information processing is solved, internal storage space using is lowered, the phenomena of border crossing and overflowing are avoided, the probability of system collapse is lowered, the speed of deleting and inserting of the track information is improved, and system operation efficiency is improved. The display control software track information processing method can be widely used in development of various radar display control systems.

Description

technical field [0001] The invention relates to the technical field of radar display and control software development, in particular to a new method for processing track information with display and control software. Background technique [0002] In the existing radar models, the processing of the track information of the radar by the display and control software is generally realized by means of an array. The specific steps of the method are as follows: firstly, the length of the array should be estimated according to the number of tracks; then, corresponding memory space should be opened according to the length of the array; finally, track storage and deletion operations should be carried out for the array variables. The disadvantages of this method are: a. Opening up an array requires a continuous memory space, which will cause many memory fragments and a large waste of space. The memory space that an embedded system can provide is often limited, so it will seriously affe...
