PyQt5+Serial+pypyodbc+win32com实现监听扫描枪串口，从ACCESS数据库中获取数据写入Excel自动打印

• 项目简介
  我公司是生产制造公司，每切换一个订单，员工需要手动填写生产记录表，填写内容包括 订单号、产品管理编号、产品名称、产品尺寸、产品类别、宽度、厚度、长度、基准重量、订单数量 等等大量信息。人工书写易出错，浪费时间。事实上，设想，我公司产品数据都保存在ACCESS数据库中，只要通过 扫描枪获取产品管理编号 便可从数据库中获取其余信息，之后将所有信息写入Excel自动打印即可。
• 关键代码如下
  ①使用PyQt5创建操作界面（为的是选取日期及核对信息用，其实没有界面也可以。Pyqt不是本次介绍重点，此处代码过于繁琐，省略。）界面如下：
  
  ②使用Serial获取扫描枪数据
  扫描枪淘宝上60几块的带USB串口功能的就可以。参照扫描枪说明书将其设置为USB串口模式。
  在电脑设备管理器中确认扫描枪的端口号，我的是COM3。端口号也可以在设备管理器中更改。

		# 此处需要导入的模块
		import serial
		import sound,winsound
		
		try:
        	# 创建Serial对象，参数为(端口号，波特率，超时时间) 为防止出错此处使用try except
            ser = serial.Serial("com3", 9600, timeout=0.5)
        except Exception as e:
            # 在D盘创建了一个错误日志，如果连接串口失败，则写入此日志。
            f = open('d:/err_info.txt', 'a')
            f.writelines(str(datetime.datetime.now()))
            f.writelines(repr(e))
            f.writelines('\r\n')
            f.close()
            ser = ''
            
            '''此处是我在本地存了一个语音错误播报音频，当出现错误时调用此音频文件,
            有需要的朋友可以到https://app.xunjiepdf.com/text2voice/进行在线转换。'''
            com3_not_found_sound_path = sound_path + 'COM3_not_found.wav'
            sound.play(com3_not_found_sound_path, winsound.SND_ALIAS)

		# 从串口对象中获取数据
        def receive(ser):
            data = ''
            try:
                while ser.inWaiting() > 0:
                	# 因为串口获取的数据类型为byte此处需要decode转换
                    data += ser.read().decode()
                return data
            except Exception as e:
                return data
                # 我设置的条形码格式为 订单号|产品编号|数量 （例：123456|CMF120-19|100）
                # 注意：条形码扫描枪仅支持英文，不支持中文。

③从ACCESS数据库中获取数据存入EXCEL
因为access数据库放在公司服务器中，如果没网的话就无法正常使用，所以我的做法是将所有数据存入到EXCEL中，仅在每次打开pyqt窗体时执行数据更新。这样平时可以使用EXCEL中的数据进行查询

此处需要导入的模块

import pypyodbc
import pandas as pd
import openpyxl
import datetime
import sound
import winsound
import time
import win32com.client

创建方法，用来获取access的数据。（因为我需要的数据在两个表中，要调用两次，所以写此方法方便调用）

# 获取access的数据。
def get_table(product_info_path, sql, names,PWD, sound_path=''):
    try:
        file_path = product_info_path
        # conn = pypyodbc.win_connect_mdb(u'Driver={Microsoft Access Driver (*.mdb, *.accdb)};PWD=8110;DBQ=' + file_path)
        conn_str = 'Driver={Microsoft Access Driver (*.mdb, *.accdb)};PWD=%s;DBQ=%s'%(PWD,file_path)
        conn = pypyodbc.connect(conn_str)
        cursor = conn.cursor()
        cursor.execute(sql)
        data = cursor.fetchall()
        df = pd.DataFrame(data, columns=names)
        return df
    except Exception as e:
        f = open('d:/err_info.txt', 'a')
        f.writelines(str(datetime.datetime.now()))
        f.writelines(repr(e))
        f.writelines('\r\n')

        print(e.args)
        return ""

将两个表的数据连接起来

def link_table(parent_access_path, product_info_path,PWD, sound_path=''):
    try:
        # 获取产品信息表
        parent_access_path = parent_access_path
        sql = "select 管理编号,名称,尺寸 from 产品列表"
        names = ['管理编号', '名称', '尺寸']
        df1 = get_table(parent_access_path, sql, names,PWD)

        # 获取式样书
        product_info_path = product_info_path
        sql = "select 管理编号,[50cm重量],[50cm重量下限],[50cm重量上限],[製品厚み],厚度许可范围下限,厚度许可范围上限,原反幅,原反幅基準下限," \
              "原反幅基準上限,インフレ幅,製品長さ,原反基准重量,原反基准重量上限,原反基准重量下限 from 现有防锈龙 union select 管理编号,'0'," \
              "'0','0',[製品厚み],厚度许可范围下限,厚度许可范围上限,原反幅,原反幅基準下限,原反幅基準上限,インフレ幅,製品長さ,原反基准重量," \
              "原反基准重量上限,原反基准重量下限 from 现有一般PE"
        names = ['管理编号', '50cm重量', '50cm重量下限', '50cm重量上限', '製品厚み', '厚度许可范围下限', '厚度许可范围上限', '原反幅', '原反幅基準下限', '原反幅基準上限',
                 'インフレ幅', '製品長さ', '原反基准重量', '原反基准重量上限', '原反基准重量下限']
        # 数字类型需转换为文本后才可以连接
        df2 = get_table(product_info_path, sql, names,PWD)
        # df2['50cm重量上限'] = df2['50cm重量上限'].apply(str)

        # 连接表
        rs = pd.merge(df1, df2, how='left', on=['管理编号', '管理编号'])
        # 字段为空无法使用contains函数
        # rs['类别'] = rs['类别'].apply(str)
        # rs = rs.loc[rs['类别'].str.contains('卷材', regex=True)]
        # print(rs)
        return rs
    except Exception as e:
        f = open('d:/err_info.txt', 'a')
        f.writelines(str(datetime.datetime.now()))
        f.writelines(repr(e))
        f.writelines('\r\n')
        print(e.args)
        return ''

将数据保存到需要打印的Excel中的data表中

# 从access更新数据库写入excel
def from_access_update_into_excel_xlsx(parent_access_path, product_info_path, database_path, PWD,sound_path):
    try:
        time = datetime.datetime.now().replace(microsecond=0)
        rs = link_table(parent_access_path, product_info_path,PWD)

        rs.to_excel(database_path, sheet_name='data')
        sound_path += 'database_update_successfully.wav'
        sound.play(sound_path, winsound.SND_ALIAS)
        return "数据库更新成功！在: %s" % (time)
    except Exception as e:
        f = open('d:/err_info.txt', 'a')
        f.writelines(str(datetime.datetime.now()))
        f.writelines(repr(e))
        f.writelines('\r\n')

        sound_path += 'database_update_failed.wav'
        sound.play(sound_path, winsound.SND_ALIAS)
        print(sound_path)
        return "数据库更新失败！在: %s" % (time)

③win32api实现自动打印

# 写入扫描信息到Excel
def scan_val_to_excel(print_file_path, jilubiao_sheet_name, jilubiao_area, rukudan_sheet_name, rukudan_area,
                      lis_jilubiao, lis_rukudan, sound_path, print_mode):
    message = ''
    print('开始传输到excel并打印')
    print('mode:'+print_mode)
    try:
        xlApp = win32com.client.Dispatch('Excel.Application')  # 打开EXCEL，这里不需改动
        xlBook = xlApp.Workbooks.Open(print_file_path)  # 将dir改为要处理的excel文件路径
        xlSht1 = xlBook.Worksheets(jilubiao_sheet_name)  # 要处理的excel页
        xlSht2 = xlBook.Worksheets(rukudan_sheet_name)  # 要处理的excel页
        for item in lis_rukudan:
            xlSht2.Cells(item[0][0], item[0][1]).value = ''
            xlSht2.Cells(item[0][0], item[0][1]).value = item[1]

        for item in lis_jilubiao:
            xlSht1.Cells(item[0][0], item[0][1]).value = ''
            xlSht1.Cells(item[0][0], item[0][1]).value = item[1]
        if print_mode == '1':
            xlSht1.PrintOut()
            xlSht2.PrintOut()
        elif print_mode == '2':
            xlSht1.PrintOut()
        else:
            xlSht2.PrintOut()
        xlBook.Close(SaveChanges=0)  # 完成 关闭保存文件
        now = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))
        message = '成功写入Excel。已传送至打印机。在：%s'%now
        sound_path += 'printing.wav'
        sound.play(sound_path, winsound.SND_ALIAS)
        return message
    except Exception as e:
        f = open('d:/err_info.txt', 'a')
        f.writelines(str(datetime.datetime.now()))
        f.writelines(repr(e))
        f.writelines('\r\n')
        print(e.args)
        message = '打印传输未知错误。'
        sound_path += 'printing_failed.wav'
        sound.play(sound_path, winsound.SND_ALIAS)
        if xlBook:
            xlBook.Close(SaveChanges=0)
        return message
    finally:
        print('打印传输完毕')
