What is the principle of the locker electronic lock? Supermarket locker electronic lock working principle introduction. The main application scenario of the locker electronic lock is a supermarket, which can facilitate the temporary storage of goods by the customer. The use method is also very simple. Most of the electronic locks are unlocked through a printed paper QR code, and the locker is opened when the shopping is ended. You can remove items. How is this complete process achieved? Locker electronic lock is based on how it works?
The locker electronic lock system is a multi-level management system combined with a locker electronic lock and a non-contact RF card key. It can realize multi-level management of locks and keys, and is applicable to supermarkets, hotels, shopping malls, entertainment and other places.
Locker electronic lock workflow introductionWhen the customer presses the "save" button, the built-in chip of the locker automatically generates a bar code and prints it into a paper bar code through a micro bar code printer. At the same time, the internal chip will automatically record the barcode, and the rules for generating this barcode are more diverse.
For example: 010001, a total of six. The first two represent the code of each sub-bin of the locker, 01 represents the number one, and the last four are random check codes.
When the customer needs to remove the item, the barcode is scanned by the scanner. The scanner will enter the data recorded on the barcode on the built-in chip. For example, 010001. At this time, the internal chip will start to check and match. Check the check code of the No. 01 cabinet and whether it corresponds to the number just entered.
If the match is successful, the chip controls door number 1 to open automatically, and the user can take away the item. Otherwise, the match fails and the electronic lock will prompt ".....".
Supermarket locker with MCS51 single-chip microcomputer as the core, automatic control cabinet door open, liquid crystal display shows no matter box number;
The cabinet lock is controlled by the solenoid valve. When the customer needs it, the “open door†button can be pressed directly before the locker. When the MCU receives a pulse signal, it sends a corresponding signal through the I/O cable to control the cabinet door lock. Solenoid valve will open the empty cabinet, customers can save the package, and close the cabinet door, the printer will receive a signal, print out a bar code, that is, the customer's open cabinet password;
When the customer needs to take the package, the barcode locker does not need to enter the password on the keyboard, just the barcode face of the password ticket on the bar code reader port can be;
The bar code reader collects the bar code information and outputs corresponding high and low level signals to the SCM system. After comparing the passwords, an open box signal is sent to the solenoid valve to open the door and the customer can take out the bag;
The electronic locker of the locker has the advantages of convenience, high confidentiality, high sensitivity, long service life, flexible form, and powerful functions.
