python-SQL从串行连接插入数据

我一直在谷歌上搜索，但我似乎无法正确地找到它。

目的：创建功能数据库。我已关闭模式，并将来自COM3的数据插入到测试2数据库表中。

import sqlite3
import serial
import time

#
con = sqlite3.connect('Sensors Database.db')
cur = con.cursor()
# # Create table Scheme-MESSDATA
#
# cur.execute('''CREATE TABLE Test2
#                (MESSID TEXT NOT NULL,gps_date TEXT NOT NULL,latitude REAL NOT NULL ,longitude REAL NOT NULL,alt REAL NOT NULL,actual_date TEXT NOT NULL,standard_pm1_0 INTEGER,standard_pm2_5 REAL,standard_pm10 REAL,atmospheric_pm1_0 REAL,atmospheric_pm2_5 REAL,atmospheric_pm10 REAL ,pm1_gt_3 REAL,pm1_gt_5 REAL,pm1_gt_10 REAL,pm1_gt_25 REAL,pm1_gt_50 REAL,pm1_gt_100 REAL,Temperature REAL, Humidity NUB,Pressure REAL ,Voc NUB)''')
con.commit()

ser = serial.Serial(
    port='COM3',  # /dev/ttyUSB0', for Linux systems
    baudrate=57600,
    parity=serial.PARITY_NONE,
    stopbits=serial.STOPBITS_ONE,
    bytesize=serial.EIGHTBITS,
    timeout=1
)

while True:
    try:
        ser.flushInput()
        podDdataIn: bytes = ser.readline()
        print(podDdataIn)
        if podDdataIn[:9] == "MESSKIT0R":
            print(podDdataIn)
        if podDdataIn[:9] == "MESSKIT02":
            print(podDdataIn)
        cur.execute(
            '''INSERT INTO Test2 VALUES ('%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s')''')
        con.commit()
        time.sleep(1)
        ser.flushInput()
        ser.write(podDdataIn)
    except KeyboardInterrupt:
        ser.close()
        break
con.commit()
#
con.close()

问题：它提交“字符串”数据，但不是实际的串行数据。是正确的运算符，或者必须将列映射到串行接口的值。可能是操作员搞错了？
