1. Plot description of application case
System starting idea:
1. At present, many bicycle rental stores are located in tourist attractions with bicycle lanes, and the procedure for renting bicycles is also quite troublesome. After confirming with the store whether you want to ride a bicycle or a co-drive, the store also needs to write on the receipt paper. Number coding and borrowing time, if you encounter holiday crowds, the waiting time will make consumers feel bored.
2. In store management, there are often some problems, such as the cooperation bicycles in the store are gone, but consumers want to rent bicycles. If this is the case, not only can not solve the customer’s needs immediately, but also spend some time to mobilize the bicycles .
3. Because of the difference in physical strength, some people may get tired from A -> B, and there is no way to return the car from the starting point.
4. Sometimes the number of hours bought may not necessarily take so much time, such as filling in the loan for 2 hours when renting.
But in fact, I only rode for one and a half hours, so I paid an extra half hour for the rental amount.
2. Application case process design
Rent:
1. When entering the store, first go through the membership data with the counter, and after the customer data is established, a membership card will be issued to the consumer. After the reader senses that it is a member of the store after reading the database behind it, the customer will be allowed to pass through the gate.
2. After choosing the bicycle by yourself, there is also a reader on the exit gate to read the tag on the bicycle. At this time, the consumer should put the card on the counter reader and let the bicycle model and the current time read on the exit gate Write it on the card.
3. Go by bike.
return car:
Bring the bicycle to the sensor at the entrance. If Reader reads the tag on the bicycle and determines that it is the bicycle in the store, you can enter the bicycle and put the bicycle in the original rental position, and then go to the exit, do the checkout action, and the card after the checkout The rented field will be CLEAR off. If you leave the store without checking out, after the reader reads it, an alarm will be generated to notify the store personnel.
manage:
In each fixed block, there will be an ultra-high frequency reader. When the number of bicycles reaches a certain lower limit, it will be on the system interface on the counter to remind the service staff in the store to mobilize the bicycles as soon as possible.

System architecture diagram
a. Member system: add member data, modify member data, delete member data
b. Leasing system: The payment and leasing procedures can be done in this system interface.
c. Detection system:
(1) Detection and identification are actions made at two doorways, which can determine whether to authorize the passage
(2) Scanning the number of vehicles, if it is below the lower limit, it will notify the store personnel
