When we stay in a hotel, we can open the door and light with a room card, which is very different from the smart door lock at home. So what is the working principle of hotel door locks? What are the functional advantages of using smart door locks in hotels? Xiaobian will introduce it to you in the following.
Working principle of hotel door lock
Hotel door lock system is mainly composed of RF circuit, electronic circuit and mechanical control. When an induction card shakes near the induction area of the door lock, the RF circuit in the door lock will immediately start and read the data in the card. If it is a system card, the door lock will compare and check the read data with the data in the lock memory. If it is invalid data or expired data, the door lock will ignore it. If it is valid data, the door lock will immediately start the internal motor to perform the unlocking operation. At this time, the cardholder only needs to gently. If it is not the system card, the door lock will not react at all.
Functional advantages of hotel door lock
1. The 16-bit processor is more powerful and more efficient than the traditional 8-bit processor.
2, with a reset protection circuit, even if there is strong interference, the circuit also ensures normal work.
3. Built-in FLASH as a memory will greatly improve the performance of EEPROM as a memory. The data storage speed is increased by one order of magnitude, and it is highly confidential and cannot be modified. The life of data erasure is 1 million times, and the life of EEPROM memory is only 100,000 times at most.
4. Built-in clock. Traditional circuits all use external clock circuits, but the external clock circuit is easy to stop the clock when the battery power supply is abnormal. With the built-in clock, the clock will slow down for a period of time at most, and there will be no big error.
5, the use of industrial-grade crystal, high-quality components to ensure high-quality products.
6, unique decoding circuit, built-in 2 sets of decoding programs, arbitrary card waving can ensure correct card reading, even if the card touches the metal shell of the door lock, it can still open the door.
7. Unique frequency locking technology can guarantee the frequency of 125kHz in any environment, and the card reading is not affected by the environment. When the temperature difference changes, it can cause the coil to expand with heat and contract with cold, which will lead to the frequency change, which will often affect the card reading, and it will be difficult to open the door seriously. Our technology has completely solved this problem.
8. Low-power design, 4 alkaline batteries of No.5, which can ensure the normal operation of the door lock for about one year. Using microwave induction technology, the battery power consumption is completely solved.
9. Built-in door opening record.
There are many ways to open the door with smart door locks at home, while the smart door locks at hotels are relatively simple, which is beneficial to the management of hotels. Nowadays, it is basically difficult for hotels and guesthouses to see traditional mechanical locks, so the advantages of smart locks are obvious.
