What is the difference between ai intelligent light box access control system and display screen access control system?
1. Different design concepts: Traditional access control products are mainly characterized by PC concept architecture in terms of superior concepts, while smart access control products are characterized by Internet architecture in terms of design concepts.
2. Different management platforms: The main feature of traditional access control products in terms of management platform is PC software, which needs to be installed locally, while the feature of smart access control products in terms of management platform is a cloud management platform, web login, and is not restricted by region. Restrictions, support mobile phone management, more convenient.
3. Difference in integration: Traditional access control products are basically difficult to integrate in terms of integration, while the integration feature of smart access control products is to provide SDK and API, which can easily connect to third-party platforms.
4. Different identification methods: Traditional access control products use IC as the main identification method, which is relatively single, while smart access control products use multiple identification methods such as QR code, face, CPU, Bluetooth, NFC, and IC. Way.
5. Different security: IC cards of traditional access control products are easy to be copied, and there are problems of being lost or forgotten to carry them. Smart access control products use mobile phones or faces as carriers, are unique and cannot be copied: CPU encryption to pre vent copying.
6. Different networking methods: Traditional access control products use offline or LAN networking methods, while smart access control products use Ethernet, WiFi, and 4G as the networking methods.

If the red one is connected to a 3K resistor, there will be about 86-95 resistors along the way.
If the blue one is connected to a 3K resistor, there will be about 51-55 resistors along the way.
The green one will be connected to a 3K resistor. If so, there are about 56-60 along the way.
The controller refers to a master device that changes the wiring of the main circuit or control circuit in a pre determined sequence and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse direction of the motor. Composed of program counter, instruction register, instruction decoder, timing generator and operation controller, it is the "decision-making mechanism" that issues commands, that is, it completely coordinates and directs the operation of the entire computer system.
Principle:
Electromagnetic chuck controller: After the AC voltage 380V is stepped down by the transformer, it is rectified by the rectifier and becomes 110V DC, and then enters the sucker through the control device. At this time, the sucker is magnetized and demagnetized. When the reverse voltage line is connected, the controller achieves the demagnetization function.
Access control controller: The access control controller works in two modes. One is the inspection mode and the other is the recognition mode. In the inspection mode, the controller continuously sends query codes to the card reader and receives reply commands from the card reader. This mode will remain until the card reader senses the card. When the card reader senses the card, the card reader generates different replies to the controller's inspection command. In this reply command, the card reader transmits the read internal code data of the proximity card to the access control controller, allowing access control. The controller enters identification mode. In the recognition mode of the access control controller, the access control controller analyzes the code number in the proximity card, compares it with the card data stored in the device, and implements follow-up actions. After the access control controller completes the action of receiving data, it will send a command to reply to the card reader to restore the card reader status. At the same time, the access control controller returns to the inspection mode.
