Abstract

The invention provides a portable measuring and controlling system for rocket engine ground tests, relating to the field of measurement and control of rocket engine tests. The system mainly comprises a computer, a data acquisition and control card and a measuring and controlling box, wherein the measuring and controlling box mainly comprises an alternating current power supply interface, a measuring and controlling box power switch, a measuring power switch, a signal isolator, a power amplifier chip, an emergency stop switch, relays and the like. The system mainly solves the problem that the existing measuring and controlling systems for rocket engine tests have low integration level and poor portability and the measuring system and control system are mutually independent. The system has the following advantages and beneficial effects: the system realizes integration of various measuring and controlling components by adopting the portable measuring and controlling box and integrates the measuring system and the controlling system; based on development of the data acquisition and control cards in National Instruments (NI), the system has high data sampling rate and multiple measuring and controlling channels; by adopting a shunt circuit switchable power supply system, the system has good safety and strong expansibility; and the system has universality and can meet the requirements of various rocket engine tests on measurement and control.

Description

technical field [0001] The invention belongs to the technical field of rocket engine test measurement and control, in particular to a portable rocket engine ground test measurement and control system. Background technique [0002] The rocket engine ground test has the characteristics of high cost and high risk, and requires a large amount of information to be obtained. At the same time, the supporting measurement and control system is required to have high reliability and precision to ensure the success and effectiveness of the test. The existing rocket engine ground test measurement and control systems are mostly fixed, with poor portability, and are often only used for specific tests, resulting in a serious waste of funds and resources. In the document Solid Rocket Technology-2001-24(4) "Solid Rocket Ramjet Ground Test Device and Measurement and Control System", Northwestern Polytechnical University established a ground test system for solid rocket ramjet based on PXI bus ...
