Surveillance of dining records in canteen
When I went to get off work, the Canteen Malaysia gave me a call and learned that the canteen data was incorrect.
I immediately logged in the computer's computer for viewing. It turns out that the card card is not running. For specific reasons, I estimate is because the password is modified during the debugging process.
It turns out that in my card reader, I also sent me another information every day, I will send me a message, which can be invalid because the company's current network has been broadcast through VLAN. This instruction has been invalid.
It seems that I have to be a monitor, how do you know if the data is normal?
My current idea is this:
1. Master a daily meal situation by monitoring the dining database of the database.
2, run the program at regular time on my computer
3, the program runs after the card is recorded in the cafeteria
4, the program sequence statistics database of cards passing in the database
This way, I can understand the work of the cafeteria card through this program.
