What are the advantages of hotel electronic door locks?

Abstract: The hotel electronic lock is a comprehensive product that uses electromagnets and lock bodies as executive components and integrates electronic technology and Internet technology. Most hotel electronic locks are centered on 51 series microcontrollers and equipped with corresponding hardware circuits to complete functions such as password setting, storage, identification and display. They have strong anti-interference capabilities, strong confidentiality, and greatly reduce replicability. , let’s take a look with the editor next. The basic structure of hotel electronic locks

At present, most hotel electronic locks are centered on the 51 series microcontroller (AT89051) and equipped with corresponding hardware circuits to complete the setting, storage, identification and display of passwords, and drive electromagnetic execution device, and detects its driving current value, receives alarm signals from sensors, sends data and other functions.

The microcontroller receives the entered code and compares it with the password stored in the EEPROM. If the password is correct, it drives the electromagnetic actuator to unlock; if the password is incorrect, the operator is allowed to re-enter the password. At most It can be entered three times; if it is incorrect three times, the microcontroller will alarm the intelligent monitor through the communication line. The microcontroller sends each unlocking operation and the driving current value of the electromagnetic actuator at that moment to the smart monitor as status information. At the same time, the alarm information received from the sensor interface is also sent to the smart monitor as a basis for intelligent analysis.

What are the advantages of hotel electronic door locks

1. The 16-bit processor is more powerful and program efficient than the traditional 8-bit processor.

2. It has a reset protection circuit, which ensures normal operation even if there is strong interference.

3. Built-in FLASH as memory will have a very big leap in performance compared to the usual use of EEPROM as memory. The data storage speed is increased by 1 order of magnitude. It has strong confidentiality and cannot be modified. 1 million times of data Erase and write life, the erase and write life of EEPROM memory is only 100,000 times at most.

4. Built-in clock. Traditional circuits use external clock circuits. However, external clock circuits are more likely to stop the clock when the battery power supply is abnormal. With a built-in clock, the clock will run slowly for a period of time at most. , there will be no large error.

5. Using industrial-grade crystal and high-quality components ensures high-quality products.

6. Unique decoding circuit, built-in 2 sets of decoding programs, any swipe of the card can ensure correct card reading. Even if the card comes into contact with the metal shell of the door lock, the door can still be opened.

7. Unique frequency locking technology can guarantee a frequency of 125kHz in any environment, and card reading is not affected by the environment. When the temperature difference changes, it can cause thermal expansion and contraction of the coil, resulting in frequency changes, which often affects card reading, and in severe cases, the door cannot be opened. Our technology has completely solved this problem.

8. Low power consumption design, 4 AA alkaline batteries, which can ensure the normal operation of the door lock for about one year. Using microwave induction technology, battery power consumption is completely solved.
