The standalone access control is an access control product that combines a card reader and a controller, and there are independent types and networked types. To put it simply, the access control all-in-one machine is a machine that integrates the access control board card, and reader. The high-end ones also include a keyboard and a display screen. It can be used as a complete access control system only by connecting to the power supply.
The access control all-in-one machine is the core control device of the access control system. It has reliable data storage, no data loss when power is off, and integrates management and automatic control. Realizing the automatic management of access control, the data can also be used for attendance, realize the double function of access control and attendance, and can be seamlessly connected with the card system at the same time.
Principle of independent access control system: Independent access control is non-network type, each door lock is independent, and its information reading is usually card type and induction type. The principle is that the card reading head is used to read the smart card information (card number) of the card reader, and then convert it into an electrical signal and send it to the access control controller. It is authorized to enter the gate during this time period and complete the work of unlocking and keeping the lock according to the judgment result.
The principle of the networked access control system: the networked access control system is composed of a controller, a card reader, and an electronic lock to open the door. It uses a computer equipped with access control system software to manage all information analysis and processing in the system. The principle is that the controller accepts the personnel information and corresponding authorization information sent from the management computer, and at the same time transmits the card-swiping record of entering and exiting the door to the computer. A single controller can form a simple access control system to manage one or more doors. Multiple controllers are connected to the computer through the communication network to form the access control system of the entire building.
The capacitive touch chip integrates a high-resolution touch detection module and a dedicated signal processing circuit to ensure that the capacitive touch chip has a sensitive automatic identification and tracking function for environmental changes. In order to facilitate the user to independently control the sensitivity of the touch key in the application, the capacitive touch chip also sets the sensitivity control bit.
The peripheral circuit is simple and easy to debug; the sensitivity of each button can be adjusted individually through programming, and it has passed lead-free certification, and the package (QFN-24L (4.00 x4.00x0.75, e = 0.50)) analog compensation circuit; embedded digital Noise filter; the CTRL pin of GTX314L provides the chip IDI2C bus that can switch two chips in parallel on the same chip.
