1. Prospect

Driven by development of global economy and rapid growth of Asian production and sales markets, the automobile industry is growing steadily all over the world. It is predicated that the global automobile output will be 97.2474 million by 2017. With increase in global automobile output and demands for automobiles and parking spaces in developing countries, the demand for parking lots will explode in the future. A total of 1.5 billion of parking lots are needed worldwide in 2017.

Companies have provided solutions for parking lot-related applications one after another to meet the huge market demands. Currently, three types of mainstream solutions are available: the traditional access controller mode, remote RFID mode, and License Plate Recognition mode, among which the traditional access controller mode still prevails in most of foreign countries. Compared with traditional parking access controllers, ZKTeco's remote Radio Frequency Identification (RFID) products are easy to use without requiring car stop before the barrier gate is opened. Besides, compared with the License Plate Recognition mode, ZKTeco's remote RFID products feature few supporting hardware, low cost, mature technologies, and easy to promote locally. In the overseas market, the remote RFID products will be of huge advantages for the deployment in parking lots.

2. Product overview

A remote RFID product, the UHF RFID Reader automatically identifies objects, vehicles, and personnel in different statuses (moving or static) through collecting and processing information of remote moving or static targets in a non-contact mode, realizing automatic management of targets. ZKTeco's UHF RFID Reader is CC- and FCC-certified, eligible for sales extensively around the world. With the IP66 water-and dust-proof certification, it can be used outdoors. Its low current and low power consumption design efficiently ensures its service life. Currently, ZKTeco has launched a complete range of solutions for the application of its UHF RFID Reader in parking lots. The effective reading distance of UHF 10 Readers is 12 m, with an optimum distance of about 10 m, serving as a hardware infrastructure for parking plot application solutions.

5. Solution

UHF RFID Reader is widely applied in parking lots due to its remote RFID features.

1) Register the UHF tag

Connect the 915 MHz card enroller to a computer, start ZKAccess3.5, and click the Personnel Profile tab to register the UHF tag, as shown in the figure below:

2) Install the UHF tag

After registration, install the UHF tag in an appropriate place on the windshield inside the car, as shown in the figure below:

Note: The distance between the UHF tag and the metal frame shall be 80 mm at least. The checked options in the figure above are recommended.

3) Install the reader

Install the reader as illustrated in the following figure:

Note: The left and right angles of the reader shall be adjusted so that the reader faces the coming vehicles.

4) Application

The remote RFID system consists of a trigger, a detector, a controller, and a reader.

• ➤ Trigger: Ground sensing detector. When a vehicle drives into an area in which the ground induction coil is laid, the ground sensing detector is triggered and the UHF Reader reads the card. The ground sensing detector is optional as long as the card can be read within the effective distance.
• ➤ Detector: UHF RFID reader. When a vehicle enters the card reading distance, the reader reads the card and transmits the card information to the controller.
• ➤ Controller: ZKTeco controllers or other common controllers available in the market. The controller verifies the card information and outputs a relay signal for cards passing verification to the barrier gate of the parking lot.
• Executor: Upon receiving the relay signal from the controller, the barrier gate is opened, and the whole remote identification is finished.

6. Note

• The reader cannot be installed in a high-voltage environment, for example, high tension wires and high-voltage transformers.
• The reader cannot be installed near metallic objects.
• If the reader is installed at a T-junction or a 90° corner or in other unfavorable environment, the reader may fail to read the card due to the overlarge reading angle. You can install an additional reader at the corner to solve the problem.
• For such terrains as slopes, adjust where the reader faces, turning it downwards within the effective range of card reading.
• Remote card reading by the UHF Reader is affected by the protective film (explosion-proof film) on car windows to some extent.
• Remote card reading by the UHF Reader is affected on rainy, snowy or windy days to some extent.
