An air cannon launch control system includes an air inlet channel, an air chamber communicated with the air inlet channel, an air outlet channel communicated with the air chamber, and a launch channel. The air inlet channel is provided with an air inlet valve; the air outlet channel is provided with an air outlet valve; the launch channel is provided with a launch valve; the air cannon launch system further includes a PLC; the gas chamber is connected with a pressure sensor for feedback of a pressure in the air chamber; and the pressure sensor, the air inlet valve, the pressure sensor, the air outlet valve and the launch valve are respectively connected with the PLC. The pressure sensor is provided for the feeding the pressure value collected in the real-time manner back to the PLC and the PLC displays the dynamic pressure value on a control interface; and the implementation of the launch program of the air cannon by the PLC is decided based on whether the real-time pressure value displayed by the control interface in the dynamic manner is stable in the set air injection pressure, so that the error by manual operation is avoided and the test precision is greatly improved.
Description
technical field [0001] The invention relates to the field of air cannon launch tests, in particular to a launch control system for air cannon launch tests. Background technique [0002] Existing air cannon launch control systems used for testing and research in the field of impact and collision usually use single-membrane rupture, double-membrane rupture, solenoid valve and other launch control technologies, and these technologies usually require visual pressure gauges, according to the pressure The pressure value on the gauge manually controls the intake pressure, then activates the launch control. Due to the accumulation of manual control errors, the error between the actual launch velocity and the design launch velocity of the projectile is often more than 3%. Therefore, the launch velocity accuracy of the existing air cannon launch control system cannot meet the test requirements. [0003] Therefore, a new technical solution is needed to solve the above problems. Cont...
