The invention discloses a helicopter VNE automatic test system and method. The system comprises a simulation excitation module which is used for reading a test case from a test case table, obtaining a sensor parameter in the test case, obtaining a VNE value based on the sensor parameter, and representing the VNE value in an air speed dial gauge of a helicopter airborne display device; an image collection module is used for performing image collection on a helicopter airborne display equipment interface by using a camera; a VNE recognition module is used for carrying out VNE parameter analysis according to the collected image; a result judgment and output module is used for reading the truth values of the powered VNE and the unpowered VNE of the test case from the test case table and carrying out result judgment on the truth values and the test values obtained through analysis, and when the difference value of the truth values and the test values obtained through analysis is within a set error range, it is judged that recognition is correct; and when all the test cases in the test case table are executed, outputting a statistical chart according to an execution result.

    本发明公开了一种直升机VNE自动化测试系统和方法,所述系统包括:仿真激励模块,用于从测试用例表中读取测试用例,获取测试用例中的传感器参数,基于传感器参数得到VNE的数值,并将该VNE数值表现在直升机机载显示设备的空速刻度表中;图像采集模块,用于利用相机对直升机机载显示设备界面进行图像采集;VNE识别模块,用于根据采集的图像进行VNE参数解析;结果判别与输出模块,用于从测试用例表中读取测试用例的有动力VNE和无动力VNE的真值,并将该真值与解析得到的测试值进行结果判别,当两者差值在设定的误差范围内,则判别识别正确;当测试用例表中的所有测试用例执行结束,根据执行结果输出统计图表。
