The right side of the lower half displays the currently acquired analog signals as a real-time curve; the left side of the lower half displays the historically stored acquired analog signals as a historical curve. Below the historical curve are screen control buttons for adjusting the display time period of the historical curve.

[0088] Furthermore, the control page also includes a data storage display button 186 , and the human-computer interaction screen 18 automatically jumps to the storage page 185 on the control page according to the triggering state of the data storage display button 186 .

[0089] Furthermore, the control system 1 also includes a control panel.

[0092] Furthermore, the control system 1 also includes a digital display, which is arranged on the control panel.

[0093] The digital display is used to receive and display the real-time data of the air chamber 28 and the backup pressure chamber 29 of the bird throwing test device 2 corresponding to the pressure sensor 16 and the temperature sensor 17 collected by the PLC controller 11.

[0094] The digital display is also used to display the received set working air pressure data of the air chamber 28 and the backup pressure chamber 29 of the bird-throwing test device 2.

[0095] Further, such as Figure 5 As shown, the control system 1 also includes a power supply module 19, which is used to provide working power for the bird throwing test device 2, the PLC controller 11, the relay array 12, the solenoid valve 13, the indicator light 14, the signal isolator array 15, the pressure sensor 16 and the temperature sensor 17.

[0097] The 380V AC power supply 191 is converted into a first electrical signal and a second electrical signal after passing through the air switch 192;

[0098] The first electrical signal is sequentially supplied to the air compressor 21 of the bird throwing test device 2 via the motor protection switch 193 and the AC contactor 194;

[0099] The second electrical signal is converted into a third electrical signal and a fourth electrical signal after passing through the circuit breaker 195;

[0103] In the local control mode, the set working pressure data of the air chamber 28 and the backup pressure chamber 29 can be set through the digital display. When the currently detected pressure value is greater than or equal to the set working pressure data, the corresponding solenoid valve 13 is controlled to close.

[0104] In remote control mode, the set working air pressure data of the air chamber 28 and the backup pressure chamber 29 can be set through the human-computer interaction screen 18. When the currently detected pressure value is greater than or equal to the set working air pressure data, the corresponding solenoid valve 13 is controlled to close, that is, when the inflation pressure reaches the set value, inflation is stopped.
