为解决流体输送管道投产前的密闭性检测问题，提出了一种基于无线通信技术和双检测定位方法的解决方案。该方案利用无线通信模块控制管道中两台检测车的行进动作，同时利用搭载在检测车上的气压检测模块完成管道中密封性的测试。当出现气压值突变时，检测车进行实时定位并通过无线方式将检测结果发送至管道一端的终端模块进行显示和记录。试验表明，该方案定位准确，且可实时显示检测结果，在流体输送管道密闭性检测过程中具有很高的应用价值。

In order to solve the problems in airtightness inspection for pre-production of fluid transportation pipelines, the solution based on wireless communication technology and twofold inspection plus positioning method is proposed. With this method, the movements of two inspection vehicles are controlled by wireless communication module, and the test of airtightness in pipeline is conducted by using the air pressure detection module equipped on the inspection vehicles. When abrupt change of air pressure occurs, positioning is accomplished in real time by the inspection vehicle, and the result is sent to the terminal module at the end of the pipeline for display and record. The tests show that the method is precise in positioning and the inspection result can be displayed in real time;it possesses higher applicable value in airtightness inspection process for fluid transportation pipelines.
