The invention relates to an automatic flow measurement system and an automatic flow measurement method of an aircraft fuel oil main pipe. An optical fiber liquidometer is arranged on each of both sides of a glass pipe of an original measurement tester; data lines of the optical fiber liquidometers are connected with an industrial personal computer through an anti-explosion safety grating and a communication converter. The automatic flow measurement method comprises the following steps: mounting the fuel oil main pipe to be tested on the measurement tester; starting a computer and starting the automatic flow measurement system of the fuel oil main pipe; calibrating the optical fiber liquid level in the automatic flow measurement system of the aircraft fuel oil main pipe; connecting an MES (Manufacturing Execution System) after calibration is finished, and receiving tasks from the MES system; selecting a certain task and setting the measurement time; starting the tester, calling an automatic data acquisition subprogram after the liquid level is stabilized, and carrying out data acquisition and processing; and exiting from the program after the task is finished and ending the measurement of one fuel oil main pipe. According to the automatic flow measurement system and the automatic flow measurement method, the flow of the aircraft fuel oil main pipe is automatically measured, data can be accurately read in, the measurement accuracy is ensured, errors caused by artificial read is avoided, the labor intensity is reduced and the working efficiency is improved.
Description
technical field [0001] The invention relates to an automatic measurement technology of an aero-engine, in particular to an automatic measurement system and a measurement method for the flow of an aviation fuel main pipe. Background technique [0002] Fuel costs are one of the main components of flight costs. The fuel used in aviation is a separate type of fuel independent of gasoline, kerosene, and diesel that people usually see. Aviation fuel is commonly called aviation kerosene because its combustion characteristics are closer to kerosene. At present, in the existing technology, the information management of the flow of aviation fuel main pipe has been realized, but the flow measurement of fuel main pipe nozzle still adopts the old-fashioned manual operation method, and the flow measurement is carried out by a set of volumetric method oil flow verification standard device, and the circulating medium is aviation kerosene. The device uses the static volume method, and the...
