摘要
为满足考场通讯设备作弊的排查检测的需要,提出一种可实现自动定位锁定通讯作弊者的算法.它的实现方式是:在计算机接受到4个信号源测距感应器反馈的距离数据基础上;首先,通过运用平面三角几何的数学工具,将4个距离数据转化为2个三角形面积数据;然后,通过使用函数转化将2个面积数据映射为一组坐标数据;最后,将坐标数据输出显示,从而实现作弊信号源的定位与锁定.
In order to solve the problem of cheating in the examination room communication equipment, an algorithm for automatic localization and locking of cheaters is proposed. It is implemented on the basis of the distance data received by the computer when the 4 signals are located from the sen- sots ; Firstly, by using the mathematical tools of plane trigonometry, 4 distance data are transformed into 2 triangle area data; Secondly, 2 area data are mapped into a set of coordinate data by using function transformation; Finally, coordinate data is output and displayed so as to realize the lock- ing and positioning of cheating signal source.
