Embodiment Construction

[0015] A kind of launch vehicle launch control signal measurement method of the present invention is described in further detail in conjunction with accompanying drawing, the concrete process of this method is:

[0016] Step 1. Initialize at the moment of starting collection, and initialize all data to a state of 0;

[0017] Step 2. After the initialization is completed, the power supply module of the conditioning circuit provides a +12V detection voltage for the input terminal of the dead emission control signal. It means that the emission control signal is not connected. When there is an uncharged emission control signal input, the circuit is connected, and the detection signal voltage of the detection terminal is +12V, and it is judged that the emission control signal is connected;

[0018] Step 3: Rectify and filter the voltage at the detection terminal, and at the same time, use the voltage conversion device of the conditioning circuit to perform voltage conversion on the...

Abstract

The invention discloses a carrier rocket launch and control signal measurement method, which realizes high-precision detection of uncharged launch and control signals of a carrier rocket in the test and launch process and flexible setting of effectiveness determination threshold of the uncharged launch and control signals, and meanwhile, can finish high-precision timing of valid and invalid statesof the launch and control signals, thereby ensuring accuracy of signal acquisition and accuracy of judgment, and providing the high-precision launch and control signals for the test and launch process of the carrier rocket.

Description

technical field [0001] The invention belongs to the field of launch vehicle testing, and relates to a high-precision and high-reliability detection method for a launch control signal of a launch vehicle without electricity. Background technique [0002] With the successful development of a new generation of digital launch vehicles and their entry into active service, the launch and control equipment of new launch vehicles based on digital signals have gradually replaced the original analog launch and control equipment. Gas, ignition, flight, and key action control play a very important role. Therefore, the high-precision measurement of the launch control signal of the launch vehicle is very important. At present, the detection of the launch control signal of the launch vehicle can only achieve high and low levels. It is impossible to achieve high-precision detection of the validity and duration of the uncharged contact type control signal. Contents of the invention [000...
