What kinds of hotel electronic door locks are there?

Hotel electronic locks are generally used in hotel management, which can be roughly divided into four types: key electronic locks, touch electronic locks and card recognition electronic locks. At present, most old hotels in China still use IC locks, and newly opened hotels generally use RF induction locks because the design of RF induction locks is sealed, safe and convenient. Next, let's look at Bian Xiao. What kinds of hotel electronic door locks are there?

1, push-button electronic lock

Use the keyboard (or key combination) to enter the unlock password, which is convenient to operate. The internal control circuit of electronic lock often adopts ASIC, and the preset password can be changed by changing the connection between keyboard (or combination button) and internal control circuit. The computer can remember more than 10000 passwords, the numbers can be changed at will, and an alarm can be set.

2. Electronic key electronic lock

Use the electronic key to enter (or act as) the unlocking password. Electronic key is an important part of control circuit. The electronic key can be composed of components or unit circuits composed of components, and made into a small handheld unit. The connection between the electronic key and the main control circuit can be acoustic, optical, electromagnetic and other forms.

Step 3 Touch the electronic lock

The unlocking password is entered by touching, and the operation is simple. Compared with the key switch, the touch switch has longer service life and lower cost, so the control circuit of the electronic lock is optimized. Using bimetallic contact to input password has good concealment and strong confidentiality. It has the function of pseudo-key locking 5S, which can drive the alarm.

4. Card identification electronic lock

Card identification electronic locks use various cards (including magnetic cards, ic cards, etc. ) as a password carrier, the electronic lock is controlled by reading the card by the corresponding card reader.

Magnetic Card Electronic Lock After the magnetic card is inserted into the card reader, the card reader reads the information in the magnetic stripe and sends it to the electronic lock controller, which performs functions such as judging, executing and recording according to the law. The working principle of ic card electronic lock is basically the same as that of magnetic card electronic lock, but because IC card will not be magnetized, its service life is longer.

Market development status of hotel locks

There are many products of hotel locks, and most of the hotel locks on the market are card identification electronic locks, including C locks, RF induction locks, TM locks and so on. At present, most old hotels in China are still using IC locks. There are two main reasons for choosing IC locks. First, the technology of IC lock has developed for so many years, and the technology is very mature, so the price is generally low. Secondly, ic card lock used to be the king on the historical stage, because it made a technological revolution compared with the previous electronics, which solved many problems and was also the stage of China's economic take-off, so a large number of hotels used IC card locks until now.

Newly opened hotels generally no longer use IC card locks, because the appearance of radio frequency induction technology has changed the concept of contact. Radio frequency induction technology can read public information through induction, which greatly facilitates the innovation of other related technologies. What we contact most now is the stored-value card of public transport system and our new-generation ID card, which are products brought by radio frequency induction technology. As far as hotels are concerned, the design of general induction locks is sealed, and there is no need to make a slot to read cards like IC locks. Just put it in the sensing area to read it, and the door opening speed is fast, so it is easy for guests to judge whether it is successful or not.

When hotels use IC cards, the IC card chip will be lost or damaged due to incorrect card insertion and long-term use by guests, and the card reader of the door lock will also be damaged, and the consumption is still very large. The induction lock is different, because it is non-contact induction, the lock itself will not be damaged by card reading, and the induction card will not be damaged by contact card reading. As long as the sensor card is not broken or violently damaged, it can basically be used for decades.
