RFID parking solution for residential parking lot with parking management softwarer parking sensor
Guangzhou Coma Ltd.offers a reliable range of automated access control systems tailored to car park application. The integrated solutions include ticket systems,swipe cards,Automatic Number Plate Recognition(ANPR) or long range RFID tag parking management system. A well designed car parking system can be a successful revenue generator.
This card reader is the combination of antenna and RFID card reader. It is compatible with passive RFID recognition standard ISO18000-6B and 6C/EPC G2. It can read and operate all the RFID tag based on above standard. Power supply interface is DC12V,communication interface RS485. RS232 and USB is optional. It is widely used in car park, access control, ETC, intelligent traffic information system, logistic monitoring, etc
RFID tag parking management system allows a non-stop,hands free vehicle access. The reading distance is more than 8m .The parkers do not need to roll down the window or get off to get a card, then there will be no stop at the entrance which can avoid the trouble of entrance peaks and bad weather.
902-928 MHz,frequency hopping is optional
>8m,it varies for different tag and environment.
standard RS485 interface, weigand 26,weigand 34. RS232,USB are optional
6dBi linear polarized antenna is installed inside
-30℃ to +65℃

Outlook of the reader
RFID tag types
The card reader is generally fixed to the column by a bracket (as below picture)
The column is installed at the road side(next to barrier),height is generally 1.8m, diameter 30-60mm
Car park application
In-out working process
VIP In-out(tag is fixed):it is auto-induction when car goes in and out without stop.
When the car comes to the entry or exit, the barrier will automatically rise up to allow access. After the car passes through the barrier, the barrier will fall down automatically. At the same time, the corresponding car plate No, card No, and entry time stored in the RFID tag will show and the data is stored in the computer.
Swing in-out: If the car anti-explosive film has a great impact for card reading, then the driver can open the window and swing the card at the distance around 2m from the card reader, or driver can slowly move forward at the distance of 5m and simultaneously reach the card out of window for reading. After reading, the barrier will open. After passing through, the barrier will automatically fall down.
About metal film
1. The anti-explosive film is mainly used for preventing people injured caused by broken glass. And there is some metal powder mixed in the film for anti- ultraviolet radiation, car inside light reflection and privacy protection. The glass is electroplated a layer of metal film in some business cars when they are produced.
2. Working principles of passive card. Since there is no battery inside, the tag gains energy for inside circuit working via irradiation from antenna. When there is metal shield between the tag and reader, the energy transmission will attenuate and reflect, causing insufficient power working for tag and the reading distance is also decreased.
3. All the passive long range reader with frequency of 915M in the international market has this problem.
A. Fix the metal tag in the car plate.
B. Open window and swing card. Driver can open the window and swing the card at the distance around 2m from the card reader, or driver can slowly move forward at the distance of 5m and simultaneously reach the card out of window for reading.
C. Cut film. Cut film for the tag, with a reserved space of 3cm around the tag.
