The invention relates to an engine high-altitude
simulation test, and provides a distributed measurement
system for an engine high-altitude
simulation test in order to solve the problems that in an existing test, the laying cost of a cable connection mode is high, and the stability of
system transmission cannot be guaranteed, and the like, and the distributed measurement
system comprises a front-end test system, a
relay point and a rear-end measurement and control center. The front-end test system comprises a plurality of sensors, at least one collector and a power supply
assembly, the collector is a multi-channel collector, and each channel is correspondingly connected with one sensor; the power end of each sensor is connected with the positive
electrode of the power supply
assembly through a cable, the
signal end of each sensor is connected with the
signal input positive end of the corresponding channel of the collector through a cable, and the
signal input negative end of the corresponding channel of the collector is connected with the negative
electrode of the power supply
assembly through a cable. A communication port of the collector is connected with a communication port of the
relay point through a cable, the communication port of the
relay point is connected with the rear-end measurement and control center through an optical cable, and the rear-end measurement and control center is used for
processing data information transmitted by the relay point.
