How does a smart locker work?

What is the principle of intelligent locker lock? Introduction of working principle of intelligent two-dimensional code locker lock. Lockers are common items, which are often used in supermarkets, bathing places, hotels, hotels, homes and other occasions. Lockers have also experienced the development stage of mechanical lock-mechanical coded lock-intelligent lock. At present, smart electronic locks are more common, and some lockers use two-dimensional code locks, which is more convenient to use. The principle is still an electronic lock, which is unlocked according to the user's fingerprint, password or mobile APP scan code.

Working principle and process of intelligent locker lock

The intelligent locker system takes the single chip microcomputer as the core, and realizes management functions such as monitoring and historical archiving by controlling the computer at the main service desk, which together constitute intelligent modern storage equipment. It has the function of information storage and reading. When the single chip microcomputer completes an access action, it transmits the information to the upper computer. After receiving the information, the upper computer analyzes it and takes appropriate measures.

It mainly includes: display update, historical archiving, alarm, etc. In addition, smart lockers also have functions such as historical inquiry and data statistics.

The locker smart lock is opened by password, fingerprint, QR code, etc. And requires power to maintain lock operation. The basis of unlocking in various ways is different, and the internal working principle is similar.

Password-type intelligent locker lock: to unlock by password, you need to enter the user password, remember the digital password, and the password is used as the original matching basis. When the user enters the password again, the system model matches, it will be unlocked automatically if it is completely correct, and it will be closed automatically if it is entered incorrectly.

Fingerprint smart locker lock: the lock is unlocked by the user's fingerprint and the fingerprint is recorded. Fingerprints are stored in a system database that supports multiple fingerprint entries. When the lock needs to be unlocked, finger recognition is put in, and the sensor obtains fingerprint information to model and compare it with the original fingerprint of the database. If the matching degree meets the requirements, unlock the lock.

The basis of unlocking passwords and fingerprints is uniqueness. Digital passwords and fingerprints have unique characteristics. Only when it meets the requirements can it be unlocked, and the types of QR codes are different.

Two-dimensional code smart locker lock: the user scans the code through the mobile phone and clicks unlock. The mobile phone obtains the information of the locker and sends an unlocking request to the server. The server receives the request, analyzes the use of lockers, allocates available lockers and sends an unlocking instruction. After receiving the instruction, the mobile phone transmits it to the electronic lock chip of the locker through Bluetooth, and the chip receives the unlocking instruction to realize automatic opening.

There is also a supermarket bar code locker lock, and its unlocking method is not exactly the same as the above introduction.

Unlocking principle of supermarket locker bar code: Press the "Save" button, and the built-in chip of the locker will automatically generate a bar code, which will be printed by a micro bar code printer. At the same time, the internal chip will record this barcode, and there are many rules for generating this barcode. For example: 0 1000 1, one ***6 digits. The first two digits represent the code of each sub-cabinet in the locker, and 0 1 represents the first cabinet. The last four bits are random check codes.

When the customer comes to pick up the goods, the barcode is scanned by the scanner. The scanner will input the data recorded on the barcode into the built-in chip. For example, 0 1 000 1 barcode number, the internal chip will start proofreading. Match the check code of teller 0 1, whether it corresponds to the number just entered.

If yes, the chip controls the cabinet door 1 to open automatically. Otherwise, prompt ". . . . . . . "

Supermarket lockers take MCS5 1 single chip microcomputer as the core, the door of the automatic control cabinet is opened, and the liquid crystal displays the empty box number; The cabinet lock is controlled by solenoid valve. When customers need it, they can directly press the "open door" button in front of the locker. After receiving the pulse signal, the single chip microcomputer sends out the corresponding signal through the I/O port line. The solenoid valve of the control cabinet door lock opens the empty cabinet, allowing customers to store their bags and close the cabinet door. The printer will receive the signal and print out a bar code, which is the customer's password to open the cabinet.

When the customer needs to pick up the bag, the bar code locker does not need to enter the password on the keyboard, but only needs to lean the bar code face of the password receipt against the bar code reader. The bar code reader collects the bar code information, outputs the corresponding high and low level signals to the single chip microcomputer system, and after comparing the passwords, sends a unpacking signal to the solenoid valve to open the door, so that customers can take out the bags.
