摘要: 文章基于在航天器地面模擬試驗中的壓力計量測試需求，針對常用的一種壓力變送器，開發(fā)了一套自動校準(zhǔn)系統(tǒng)。通過在LabVIEW平臺上設(shè)計虛擬儀器測控軟件，實現(xiàn)了自動控制校準(zhǔn)設(shè)備、自動生成證書和自動創(chuàng)建壓力變送器參數(shù)登記本及計算校準(zhǔn)費等，提高了壓力變送器的校準(zhǔn)效率和測量精度，滿足了日常工作的需要，保證了航天器地面模擬試驗中壓力測量數(shù)值的準(zhǔn)確性。Abstract: This paper presents a pressure transmitter in the space environment simulator. With its hardware and software, the automatic controlled calibration, the automatic certificate generation, the automatically created parameter registration book and the calculation of the calibration fees are achieved. The efficiency and the measurement accuracy are improved for the pressure transmitter. The accuracy ofthe pressure measurement in the spacecraft environment simulator is ensured.
