Research And Implementation Of Battlefield Situation Information System Based On GIS

With the development of computer technology,the development of information technology in various fields has become a trend.In the military field,turning to informationized warfare has become the main direction of current research in various countries.In the early days,people can only understand the general information of the terrain through the plane map or the sand table model.The real-time dynamics of the front battlefield cannot be grasped for the first time,which affects the correctness of the decision.In today’s world,the introduction of geospatial information system(GIS)into the battlefield situation system can transform the real environment geographic information into digital information.The rear commander can obtain the battlefield situation information without being in the front battlefield.The situation information is represented on the electronic map.Realistic information reflected by the military standards of various entities.In view of the fact that the traditional battlefield situation system can only read abstract information and easily cause ambiguity,this paper combines multimedia information with situational information,and can view the real situation of the battlefield in front through pictures or videos.The military standard on the map is divided into static military standard and dynamic military standard.The static military standard is the commander’s deployed on the map to simulate various resources of the operation,and the dynamic military standard can transmit the multimedia information of the individual soldier terminal.The posture of the soldier terminal changes and changes.This greatly improves the readability of situational information and supports decision making.The work done for this article is as follows:1)Introduced the implementation of vector graphics plotting on the map and the geometric principle of the two-dimensional transformation of the military standard.The paper proposes the movement and scale problem that the military standard needs to solve on the GIS map,and proposes solutions.Finally,the practicality and correctness of the vector graphics plotting technique are verified by experiments.2)Calculate the posture information of the individual soldier terminal.The attitude angle is calculated from the magnetic field strength and angular velocity measured by the gyromagnetic compass of the individual soldier terminal.Aiming at the problem that the magnetic compass is easily affected by external factors,this paper proposes a twenty-four point compensation correction algorithm,which inversely calculates the magnetic field distribution when the interference is not disturbed,and obtains the corrected data.After obtaining the data,the quaternion method is used to calculate the attitude angle,and the fourth-order Runge-Kutta method is used to solve the differential equation to improve the accuracy and speed of the calculation.Finally,the reliability of the algorithm is verified by simulation experiments.3)System design and function realization of the system.In this paper,the overall architecture of the system is designed.Four subsystems are designed for the requirements of the system: situation processing subsystem,text communication subsystem,remote monitoring subsystem,and reconnaissance equipment monitoring subsystem.The four subsystems were implemented and some of the technical details were presented.After actual testing and operation,the system has been applied in national defense projects and achieved good results.
