Features of Vehicle Entry and Exit Management System:
1. RFIDRadio Frequency Identification is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets.
2,RFIDThe active radio frequency card is composed of an embedded processor and its software, a transmitting and receiving antenna in the card, a transceiver circuit and a high-energy battery. The special number is pre-stored in the microcontroller, and a unique encrypted identification code radio signal is transmitted intermittently. The high-energy battery in the card provides energy for the normal operation of the active card, and the battery in the card can be replaced.
3. The directional reader/industrial-grade omnidirectional reader is composed of information collection, processing, information transmission, and embedded software. Its main function is to complete the real-time collection and processing of vehicle identification code output signals.
4. Low-frequency activator 125KHZ low-frequency signal transmitter device, used to transmit 125KHZ low-frequency signal to activate, trigger, and wake up the electronic tag working at 2.4GHZ frequency, so that the electronic tag sends a signal.
5. Vehicle sensors are used to detect metal objects such as vehicles and bicycles, and are suitable for parking lots, highway vehicle toll stations and signal light control systems. Adopting the most advanced microprocessor technology, it can meet the application in various use environments. When a metal object passes through a coil buried under the road, because the metal conductor changes the inductance of the coil, the vehicle sensor detects the metal object by detecting the change in the inductance of the coil.
The tag is placed in the car. When the car is near the door of the unit, the tag will be activated by the 125K signal from the ground line of the low-frequency activator.
After activation, the 2.4G signal of the tag is in working state at this time, and 2.4G signal (ID number) is sent out.After receiving the 2.4G signal (ID number) of the tag from the long-distance omnidirectional reader next to it, the relay in the 2.4G long-distance omnidirectional reader device will work and give a switch signal for the control of opening the door. Board, the control board receives 2.4G long-distance omnidirectionalReaderAfter the switch signal is given by the device, it will actively send out voltage to the door-opening motor. At this time, the door-opening motor works to open the door of the entry and exit unit.
After the vehicle leaves the unit door and leaves the 125K low-frequency activation area, the 2.4G signal of the 2.4G electronic tag stops working. After the 2.4G long-distance omnidirectional reader cannot read the 2.4G electronic tag, the 2.4G remote reader The relay will stop sending the switch signal to the control board. At this time, the door opening control board will stop sending the door opening voltage to the unit door motor. The door opening control board will automatically give a door closing voltage, and the unit door will automatically close.
