Detailed introduction of Bluetooth access control technology

Nowadays, with the arrival of the information society and the continuous development of science and technology, people are aware of safety precautions, so the application of access control system is more and more extensive. On the one hand, with the continuous improvement of the access control system, more and more technologies are applied in the access control system, among which Bluetooth technology has also been successfully applied in the access control system, and there are many kinds of Bluetooth access control, which meet the security requirements in various fields. On the other hand, with the development of intelligence, the access control system has gradually abandoned the card swiping operation and replaced it with Bluetooth access control technology. Let me take a look at the detailed introduction of Bluetooth access control technology.

The types of Bluetooth access control generally include construction site Bluetooth access control system, wireless Bluetooth access control system, remote Bluetooth access control system, community Bluetooth access control system and various buildings and parking lots.

Bluetooth technology is safe and reliable.

Bluetooth access control technology is synonymous with low power and short distance wireless communication technology standards. Its essence is to establish a universal open standard of wireless air interface and its control software, which further combines communication with computer.

So that portable devices produced by different manufacturers can have interoperability and interactive operation performance in a short distance, without wires or cables being connected with each other. Generally speaking, its connection range is between 10 cm and 10 m; If the transmission power is increased, the connection range can be extended to 100 meters. The transmission distance of devices using Bluetooth access control technology is not very far.

In order to solve this kind of problem, a certain relay device is often equipped in the actual use process. In this way, the whole connection can effectively achieve interoperability, and then improve the reliability of the system. In addition, the use of repeaters can also provide a good opportunity for future product upgrades. Using Bluetooth technology, the installation cost of products will be significantly reduced, mainly in two aspects: labor cost and resource cost. The reduction of cost can also promote the sales of products in turn, which in turn will greatly reduce other related expenses. In the access control industry, most systems adopt RS-232 and RS-485 hardware interface standards to connect various card readers and monitoring equipment. If the facilities to be monitored are not wired in advance, then we have to make holes in the building.

Only in this way can appropriate monitoring equipment be installed. Now with Bluetooth technology, we can avoid this phenomenon. Moreover, Bluetooth technology can provide us with more secure communication guarantee. Access control equipment using Bluetooth technology can be used in many fields. The following are some examples: Access control field: As mentioned above, products using Bluetooth technology can greatly reduce the wiring work in smart card system, making it very easy to update products. application area

Industrial automation field: In this field, Bluetooth devices can replace the connection between computers and other devices, making the connection more reliable. In addition, we can also use Bluetooth to build a wireless LAN. Energy, oil and gas fields: There are usually quite a few valves, pipelines and circuits in these fields. We can configure sensors with Bluetooth function in some key parts, so as to know the safety situation of the above parts in time. In case of danger, relevant personnel can respond in the shortest time.

The above is the Bluetooth access control technology for everyone. In fact, security is very important for modern society. After all, many things are expensive now. Without good preventive techniques and measures, it is impossible to ensure everyone's property and life safety. The development of Bluetooth access control technology not only simplifies the process, but also greatly reduces the opening time of residents. With the development of science and technology, more and more technologies will be used in our life and will make our life more convenient and comfortable.

More comfortable.
