Automatic Barrier Arms: Everything You Need to Know
What Are Automatic Barrier Arms?
Automatic barrier arms are mechanical gates that use a horizontal arm to block or allow vehicle passage. Firstly, they are often seen at toll booths, parking garages, and private entrances. Additionally, these systems are controlled electronically, making them efficient and reliable for managing vehicle access.
How Do Automatic Barrier Arms Work?
Automatic barrier arms operate through an electric motor connected to a control system. For instance, when a vehicle approaches, the system receives a signal to either raise or lower the arm. Additionally, this signal can come from various access control devices, such as keypads, card readers, or RFID systems.
Steps in the Operation of Automatic Barrier Arms:
- Vehicle Approaches: First, a sensor detects the approaching vehicle.
- Access Signal: Secondly, the driver provides access credentials, such as an RFID tag or a key card.
- Signal Processing: Next, the control system verifies the credentials.
- Barrier Movement: Lastly, the motor raises the arm, allowing the vehicle to pass.
- Closure: After the vehicle passes, the arm lowers back to its blocking position.
Types of Automated Barrier Arms
Electromechanical Barrier Arms
These are the most common types and use an electric motor to raise and lower the arm because they are suitable for medium to high-traffic areas. In fact, automatic barrier arms can operate efficiently in various weather conditions.
Hydraulic Barrier Arms
Secondly, hydraulic barrier arms use hydraulic power to move the arm. In fact, they are known for their durability and are ideal for high-security areas where the barrier needs to withstand significant force.
Manual Barrier Arms
While not automated, manual barrier arms are worth mentioning. They require a person to physically move the arm since these are often used as a backup in case of power failures.
Estimated Pricing
The cost of automated barrier arms varies based on the type and features. Here is a pricing overview:
- Electromechanical Barrier Arms: $1,500 – $3,000
- Hydraulic Barrier Arms: $2,500 – $5,000
- Manual Barrier Arms: $500 – $1,000
However, these prices can fluctuate based on features like lighting, speed of operation, and integration capabilities.
Integration with RFID Readers and Transponders
Automated barrier arms often work with RFID systems to enhance security and efficiency. Here’s how they integrate:
RFID Readers
RFID readers are devices that communicate with RFID tags attached to vehicles. For example, when a vehicle with an RFID tag approaches the barrier, the reader sends a signal to the control system to verify the tag’s information.
RFID Transponders
RFID transponders are the tags attached to vehicles. They store data that is read by the RFID reader and these tags can be passive. For instance, they require no power from batteries because their power source comes from the reader.
Working Together
- Tag Reading: Firstly, the vehicle approaches then the RFID reader detects the transponder.
- Data Transmission: Secondly, the reader sends the tag’s data to the control system.
- Verification: Next, The control system checks if the tag is authorized.
- Barrier Operation: Finally, the barrier arm raises, allowing the vehicle to pass.
