Question

这是我的光束传感器代码：

#!/usr/bin/python

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BOARD)

GPIO.setup(12, GPIO.IN) #Right level-1

GPIO.setup(16, GPIO.IN) #Right level-2

GPIO.setup(18, GPIO.IN) #Right level-3

while True:

    if (GPIO.input(12) == 1 or GPIO.input(16) == 1 and GPIO.input(18) == 0):  
        print("lying down")
        time.sleep(1)
    elif (GPIO.input(12) == 1 or GPIO.input(16) == 1 and GPIO.input(18) == 1):
        print("Sitting/Crawling")
        time.sleep(1)
    elif (GPIO.input(12) == 0 or GPIO.input(16) == 0 and GPIO.input(18) == 1):
        print("Almost out")
        time.sleep(1)
    else:
        print("Out of the crib")
        time.sleep(1)

这是我的数据库代码：

#!/usr/bin/env python

import MySQLdb


db = MySQLdb.connect("localhost", "root", "raspberry", "cribdb")
curs=db.cursor()

curs.execute ("""INSERT INTO tbstatus values(NOT NULL, 'STATUSHERE')""")

db.commit()

number_of_rows= curs.execute("SELECT * FROM tbstatus")

if (number_of_rows <= 5):
   print(number_of_rows)

else:

    curs.execute("""DELETE FROM tbstatus order by id LIMIT 1""")
    db.commit()
    print("\n Record Deleted successfully ")

如何获取传感器打印的状态（躺下，坐姿/爬行，站立等）并将其放在此处

(curs.execute ("""INSERT INTO tbstatus values(NOT NULL, 'STATUSHERE')"""))

存储在我的数据库中。

除非我对事情有误解，否则您可以简单地合并这两个脚本，例如

jrepl.bat /?

顺便说一句，我建议您在#!/usr/bin/python import RPi.GPIO as GPIO import time import MySQLdb db = MySQLdb.connect("localhost", "root", "raspberry", "cribdb") GPIO.setmode(GPIO.BOARD) GPIO.setup(12, GPIO.IN) # Right level-1 GPIO.setup(16, GPIO.IN) # Right level-2 GPIO.setup(18, GPIO.IN) # Right level-3 last_status = None while True: input_12 = GPIO.input(12) input_16 = GPIO.input(16) input_18 = GPIO.input(18) if input_12 == 1 or input_16 == 1 and input_18 == 0: status = "lying down" elif input_12 == 1 or input_16 == 1 and input_18 == 1: status = "Sitting/Crawling" elif input_12 == 0 or input_16 == 0 and input_18 == 1: status = "Almost out" else: status = "Out of the crib" time.sleep(1) if status != last_status: print(status) last_status = status curs = db.cursor() curs.execute( """INSERT INTO tbstatus values(NULL, %s)""", (status,) ) db.commit()表中添加某种类型的时间戳列，除非您已经有一个时间戳列。

~~另一个改进可能是仅记录状态更改时的状态。~~

编辑：我添加了跟踪最后状态的功能，并且仅按照评论的要求记录更改。
