树莓派：基于物联网做的指纹打卡器

　　今天我就分享一波自己的成果。

　　心心念念的想做一个物联网的东西出来，终于在上个月搞定了，虽说肯定是有些漏洞（目前我是没有找出来的），但是效果看起来还不错。学了这么久的Python、Qt、liunx命令总算派上用场了。

材料：

• 树莓派一台
• 指纹模块（AS608光学指纹识别模块）
• OLED液晶屏
• usb转TTL
• 杜邦线

先说明一下

博客园无法分享附件就只能这样分享了

如果想要附件可以点击下面 链接，我在csdn上注册了一个号可以去下载：

树莓派上的源码下载

电脑上的上位机源码下载

oled上的字体

先上个最终成果的图

           

看起来感觉还可以，基本完成了电脑和手机都可以获得日志的效果

大家最期待的过程了

　　现在我来说是我的想法和思路

　　刚开始看到隔壁实验室的指纹打卡机时好像是那种用usb读取数据的（好像是节约成本吧），我就想能这也太不智能了吧，就想着能不能让它智能些，比如通过电脑看到它的日志啊，或者用手机看到它的日志啊什么的（后来我才知道淘宝上TM已经出现这种完善的成品指纹考勤机了）。光想没用啊，还是要靠实践来检验真理。于是我就想到了手上的树莓派，想想就有些兴奋，可以向网上那些大佬一样DIY一个东西出来了，由于我的知识有限，无法自己搞个指纹打卡模块，就到网上买了一个，先开始买的正点原子的指纹模块，原子哥不愧是我原子哥，和他讨论问题时真是尽心尽力。文档很好，不过他那个和模块通信的程序不是很全，就几个，可以能是直接储存在模块里的缘故，可是我不想储存在模块里啊，我学了Python加上Mysql，我想直接存在数据库里，这样更加安全可靠。于是我就开始解决通信问题，将他发回来的数据解码，捣鼓了2天才完成，有点心酸。

先把配置文件分享了，下面代码会用到

# 用户root 给电脑连接的
[root]
pwd = 123

# 数据库
[db]
db_port = 3306
db_user = root
db_host = 127.0.0.1
db_pwd = 123456
db_database = finger
db_table = test1

# smtpServer 发送请求服务
# popServer 接收请求服务
# smtpSrcAddr 服务端的地址
# smtpSrcAddrPwd 服务端的密码
# smtpDstAddr 发送的目的邮箱
# smtpPort 端口号  qq端口号为 465
[email]
smtpServer = smtp.qq.com
popServer = pop.qq.com
smtpSrcAddr = 发送请求的你的邮箱
smtpSrcAddrPwd = 允许的密码
smtpDstAddr = 目的邮箱
smtpPort = 465

# TCP服务
[TCP]
ip = 192.168.137.249
port = 9090

# 串口服务
[serial]
port = /dev/ttyAMA0  （先不用这个串口，这个是我配置过的，你可以先用usb转ttl连接树莓派的usb口和指纹模块）
baudrate = 57600
timeout = 10

# 乐联网 网关信息
[lewei]
ip = tcp.lewei50.com
port = 9960
userKey =  你自己的userKey
gatewayNode = 02

1.首先要在电脑上调通指纹发送数据的所有命令

 分享一波代码

要用电脑和指纹模块通信首先要装

python要serial模块，在cmd命令行中用命令 pip install serial 就可以下载serial 了

    0x03: 103,  # 表示录入指纹图像失败；

 注意：

1. 可以先在串口调试助手上输入命令，看看数据是怎么样子的然后在分析数据，最后写程序处理数据
2. 按照说明书提示最好不要改 模块的地址和密码，不然可能会成为砖头
3. 非常重要！！！本人是吃了亏的，真是日了狗， 指纹模块中有个设置波特率的，说明书上是说波特率可以设置为9600倍数，其实并不是这样的，我先开始觉得速度太慢了就设置了先开始是12倍，觉得可以用还是太慢，就设置了24倍，还是可以用，但是还是慢，我一冲动就设置成了96倍，我的个乖乖，然后就是不管怎么唤它都没反应，为此我还和原子哥讨论了很久，结果就是这东西成板砖了。 然后不得已就又买了个便宜的（原子哥虽然服务好，技术支持好，就是东西太贵了，弄懂原理了就不用再买贵的了）。

2.就是写一个服务器和客户端啦

我是用Qt写的客户端，用python写的服务器，模拟两个电脑通信（虽然只要一个自己的电脑）

 先来一波服务器的代码

里面用到了mySql, 用来存储指纹数据

 同时为了上传图像到客户端还要下载numpy, PIL 模块，其中python3中没有PIL 要下pillow

用到的cmd命令 pip install numpy，  pip install pillow
