This paper is aimed at studying the issue about coverage and repair of mobile intelligent mines. Under the premise of detailed information about target area and free movement and accuracy location of intelligent mines, a research strategy based on meshing is promoted. According to the practical work process of mobile intelligent mine, taking into account the energy-saving factors, a specific coverage algorithm to form the grid in minefield was given firstly. Then, by adopting the distributed information fusion topology, an information fusion algorithm for minefield gap was provided, in which the threshold of neighbor node number is used as the criterion. Finally, in order to solve the problem of rectangular gap in minefield, designed a meshing repair algorithm according to the degree of minefield damage. The results show that the method is feasible and rational, and it can realize compiling simulation application program under MFC platform.
