Background technology
The highest level of military training is manoeuvre, and the highest level of manoeuvre is antagonism.The tactical confrontation training is two units, commanding agency or interim training marshalling; Lead under the organizing and coordinating of regulating mechanism at one; Adversary and condition are pressed corresponding each other training problem and unit equipment separately, theories for military operations, to simulate the tactical training that belligerent mode is carried out each other.The tactical confrontation training comprises antagonism operation and maneuvers.Maneuvers is the advanced form of antagonism training, usually by tide of battle, under approximate environmental condition under battle conditions, implements.It has the characteristics such as inspectability of integrality, the continuity of time and the effect of content.Tactical confrontation is trained new theories for military operations of organizational capacity, research and the exploration of the army's tactical training level of can checking, leader office and tactics etc.Tactical confrontation mainly is divided into war game antagonism, computer simulation antagonism and three kinds of forms of armed forces in real combat antagonism.
Along with the modern sensor networks development, wireless sensor network technology moves to maturity, and becomes hot research in recent years based on the third generation personnel positioning tracking system of wireless sensor network technology.Therefore the application of WSN technology aspect the national defence field has more national strategy meaning and social and economic significance.Along with the proposition of wireless sensor network technology, people have had new understanding to the seizure of military exercise and even battle field information.As far back as programme division of U.S. Department of Defense (DARPA) in 1978, begin to subsidize the research that CMU carries out distributed sensor networks.1992, US military employing wireless smoke gas sensor node gps system successfully in the Gulf War was passed to headquarter with enemy battlefield action message, carries out pinpoint bombing in real time, has brought into play crucial use afield.From the beginning in 2002; U.S. Department of Defense and each military service have all given great attention to wireless sensor network; Its C4KISR plan; Stress battlefield information perception, information integration capability and information utilize ability, as an important research field, set up series military sensor network research project to wireless sensor network; " the microsensor network service " of ground force, " the netted sensing system " of naval will make today state-of-the-art ASCM also can be by real-time monitoring and by being hit.
Hence one can see that, and it is a kind of trend that wireless sensor network is applied to military affairs, and really wireless sensor network technology be applied to military exercise ruling auxiliary system just seldom, perhaps corresponding cost is too high and can't realize.Wireless sensor network is based on the wireless communication protocol of IEEE802.15.4, have low in energy consumption, self-organizing, characteristics such as adaptive capacity to environment is strong.Therefore be highly suitable for open-air large area as military exercises.
At present, wireless sensor network is mainly used in medical treatment and nursing, environmental monitoring and protection and military field.Current domestic research institution such as learned societies such as the Chinese Academy of Sciences, Tsing-Hua University, the National University of Defense technology, University of Electronic Science and Technology, Harbin Institute of Technology and Zhejiang University have carried out follow-up study to wireless sensor network.But really wireless sensor network technology be applied to the military confrontation manoeuvre research and realization report seldom.

The real-time display module of military exercise:
At first the army that takes part in a performance is carried out initialization, be sensor node id information that carries the GPS module of unit coupling with the class, and in data memory module, preserve; Obtain data then from the serial data communication module; The decision node id information, army's kind, initiate id information; Be identified on the military exercise map with different icons, and use different color according to army's kind; Existing ID nodal information; Then according to longitude and latitude data message and original icon described point line, the army's services of taking part in a performance that belong to a side together identify with same hue, as the army that takes part in a performance is divided into red and indigo plant side; Red adopts redness to describe military line, and military line is described with blueness by indigo plant side; In time T, the data message (mainly being node ID information and perception data information) that obtains according to serial ports periodically with different color and the Data Update side combat effectiveness of the troops state of taking part in a performance, and shows whole war posture situation in real time.
Military exercise history playback display module:
At first obtain from the initial data in the database, choose the military exercise time period of playback, the military exercise army that selection needs selection to check plays the historical data segmentation of reading, and when avoiding mass data to read, causes and plays slack consequence; In the history playback process; Historical data has been carried out data analysis; Relevant information by longitude and latitude and time; Judge the state of development of whole military exercise situation, in whole military exercise process, be divided into 5 kinds to the army's situation of taking part in a performance: army's travel condition (A), army's coherent condition (B), two armies pitted against each other fight state (C), army surround state (D) and the army state (E) of retreating in defeat; And adopt envelope to describe whole war posture.
A. army's travel condition:
In time T, calculate army's translational speed according to latitude and longitude information, if the direction of advance of army's kept stable, then sign army travel condition on the military exercise map.
B. army's coherent condition:
In time T, judge that according to latitude and longitude coordinates information if certain side has many armies in the same area scope, coordinate does not have too big variation, and near distance B, do not have adversary forces to occur, then on the military exercise map, be designated army's coherent condition.
C. two armies pitted against each other fight state:
In time T, according to the relevant situation analysis of front, and latitude and longitude information, if in the same area scope, there is different services army to occur, and in distance B, latitude and longitude coordinates does not have big variation, then sign two armies pitted against each other fight state on the military exercise map.
D. army surrounds state:
In time T, according to the relevant situation analysis of front, and latitude and longitude information, if both sides' direct of travel basically identical, and distance remains in the D, and latitude and longitude coordinates changes greatly, then on the military exercise map according to direct of travel, identify army and surround state.
E. army's state of retreating in defeat:
In time T, according to the relevant situation analysis of front, and latitude and longitude information, if both sides' direct of travel basically identical, and distance remains in the D, and latitude and longitude coordinates changes greatly, then on the military exercise map according to direct of travel, identify army's state of retreating in defeat.
