基于Phyphox的F-16战斗机座舱模拟Python代码窗口短暂弹出即关闭问题排查请求

Let's break down why your window closes immediately and fix the issues one by one:

1. Critical Syntax Error (Immediate Crash Cause) #

The most obvious culprit is a typo in your HUD print line that breaks valid Python syntax:

print(f" SPD: {speed_knots:3.0f} KTS | V-ANGLE: {data['pitch'] consultancy:+2.0f} | ALT: {alt_ft:5.0f} FT")

The random consultancy word is misplaced here—this will cause an instant syntax error that crashes your script before anything renders. Fix it to:

print(f" SPD: {speed_knots:3.0f} KTS | V-ANGLE: {data['pitch']:+2.0f} | ALT: {alt_ft:5.0f} FT")

2. Stop Swallowing Errors (Debug Visibility) #

Your get_data function uses a bare except: which hides all errors—you can't tell if there's a connection issue, missing sensor data, or other problem. Replace it with specific exception handling to see what's going wrong:

def get_data():
    try:
        url = f"{PHYPHOX_URL}/get?acc&att&light&location"
        r = requests.get(url, timeout=0.5).json()['buffer']
        return {
            "acc": r['acc']['buffer'][0],
            "pitch": r['att']['buffer'][0],
            "roll": r['att']['buffer'][1],
            "lux": r['light']['buffer'][0],
            "lat": r['location']['buffer'][0] if 'location' in r else 0.0,
            "lon": r['location']['buffer'][1] if 'location' in r else 0.0,
            "alt_gps": r['location']['buffer'][2] if 'location' in r else 0.0,
            "speed_gps": r['location']['buffer'][3] if 'location' in r else 0.0
        }
    except requests.exceptions.RequestException as e:
        print(f"Connection error: {e}")
        return None
    except KeyError as e:
        print(f"Missing sensor data: {e}")
        return None
    except Exception as e:
        print(f"Unexpected error: {e}")
        return None

This way, you'll get clear feedback if something fails during data fetching.

3. Run from a Terminal (Not Double-Click) #

If you're launching the script by double-clicking the .py file, any errors will close the window instantly without showing you details. Instead:

• Open a command prompt/terminal
• Navigate to your script's folder
• Run it with python your_script_name.py
  This keeps the window open so you can see error messages or the cockpit display.

4. Verify Phyphox Connection & Permissions #

• Ensure your phone (running Phyphox) and computer are on the same Wi-Fi network
• Double-check PHYPHOX_URL matches the IP shown in Phyphox's web server settings
• Confirm Phyphox has permissions to access all requested sensors (location, accelerometer, etc.)
• Test the URL directly in your browser: http://192.168.1.55:8080/get?acc&att&light&location—you should see JSON data if everything is working.

5. Minor: Fix AOA Calculation (Placeholder Note) #

Right now you're using pitch for Angle of Attack (AOA), which isn't accurate (AOA is the angle between the wing chord and oncoming air). For now, add a note to remind yourself this is a placeholder, or plan to calculate it using accelerometer/gyro data later.

Final Fixed Code #

Here's the script with the syntax error fixed and improved error handling:

import requests
import time
import os

# --- CONFIGURATION ---
PHYPHOX_URL = "http://192.168.1.55:8080"

def get_data():
    try:
        url = f"{PHYPHOX_URL}/get?acc&att&light&location"
        r = requests.get(url, timeout=0.5).json()['buffer']
        return {
            "acc": r['acc']['buffer'][0],
            "pitch": r['att']['buffer'][0],
            "roll": r['att']['buffer'][1],
            "lux": r['light']['buffer'][0],
            "lat": r['location']['buffer'][0] if 'location' in r else 0.0,
            "lon": r['location']['buffer'][1] if 'location' in r else 0.0,
            "alt_gps": r['location']['buffer'][2] if 'location' in r else 0.0,
            "speed_gps": r['location']['buffer'][3] if 'location' in r else 0.0
        }
    except requests.exceptions.RequestException as e:
        print(f"Connection error: {e}")
        return None
    except KeyError as e:
        print(f"Missing sensor data: {e}")
        return None
    except Exception as e:
        print(f"Unexpected error: {e}")
        return None

def main():
    while True:
        data = get_data()
        if data:
            # Convert units
            speed_knots = data['speed_gps'] * 1.94384
            alt_ft = data['alt_gps'] * 3.28084
            
            # Render cockpit
            os.system('cls' if os.name == 'nt' else 'clear')
            print(f"\033[92m") # Green HUD color
            print(f" SPD: {speed_knots:3.0f} KTS | V-ANGLE: {data['pitch']:+2.0f} | ALT: {alt_ft:5.0f} FT")
            print(f" " + "—"*50)
            print(f" Pitch: {data['pitch']:+4.1f}°")
            print(f" Roll: {data['roll']:+4.1f}°")
            print(f" AOA: {data['pitch']:4.1f}°  # Placeholder, not actual AOA")
            print(f" " + "—"*50)
            # MFD Section
            print(f"\n [ G-LOAD ] [ AMBIENT ] [ NAVIGATION ]")
            print(f" ---------- ----------- --------------")
            print(f" {data['acc']/9.81:4.2f} G {data['lux']:5.0f} LUX LAT: {data['lat']:.4f}")
            print(f" LON: {data['lon']:.4f}")
            print(f" ---------- ----------- --------------")
            print(f"\033[0m") # Reset color
        time.sleep(0.1)

if __name__ == "__main__":
    main()

Try these fixes, run the script from a terminal, and you should either see your cockpit display or get clear errors to debug further.
