中文说明：在500*500的监控区域内，随机部署110个有向传感器节点。其传感半径为60，传感角度为90°。使其位置固定，传感方向可调，在程序中是通过改变50次的传感方向，实现覆盖率最大化，并把覆盖率最大的传感部署图显示出来。
English Description：
In the 500 * 500 monitoring area, 110 directional sensor nodes are randomly deployed. The sensing radius is 60 and the sensing angle is 90 degrees. The position of the sensor is fixed and the sensing direction is adjustable. In the program, the sensing direction is changed 50 times to maximize the coverage, and the sensor deployment diagram with the largest coverage is displayed.
