Parking Barrier Gate Parts Accessories Technical Details
Boom Arms and Barriers
Boom arms, the primary physical deterrent, come in various configurations including straight, articulated, and fence-type. Material choices typically include aluminum alloy for lightweight and corrosion resistance, or reinforced steel for high security applications. Key specifications involve length, often ranging from 2 to 6 meters, and profile shape, influencing wind resistance and visibility. Some boom arms integrate LED lighting for enhanced visibility, especially during low light conditions. Anti-crash features, such as breakaway connectors or rubber edges, are critical for vehicle and pedestrian safety, minimizing damage upon impact. Articulated arms are specifically designed for low headroom environments like underground parking garages.
Motor and Drive Mechanisms
The motor and gearbox assembly is the core operational component. Common motor types include DC brush or brushless motors for quiet operation and precise control, and AC motors for robust, high-torque applications. Crucial parameters include motor power in watts, operating speed defining opening/closing times, and duty cycle indicating the frequency of operation before overheating. Gearboxes translate motor rotation into the lifting and lowering motion of the boom, with worm gear or planetary gear designs being prevalent, chosen for efficiency and durability. Integrated encoder feedback systems provide precise boom position tracking for smooth operation and safety.
Control Boards and Logic Units
The control board acts as the brain of the barrier gate system, managing all inputs and outputs. Features often include programmable opening/closing speeds, auto-close timers, and pedestrian pass modes. Connectivity options like RS485, TCP/IP, or Wi-Fi enable integration with broader access control and parking management systems. Advanced control boards support loop detector inputs, photocell safety beams, and alarm outputs. Programming interfaces vary, from DIP switches to sophisticated software suites for fine-tuning operational parameters and diagnostic monitoring. Overload protection and surge suppression are standard for electrical system longevity.
Safety and Detection Sensors
Safety sensors are indispensable for preventing accidents. Photoelectric safety beams create an invisible infrared curtain, immediately stopping or reversing the boom if interrupted. Loop detectors sense the presence of vehicles via inductive loops embedded in the ground, triggering opening or preventing closure. Radar sensors offer more advanced presence detection, unaffected by environmental conditions like fog or heavy rain, and can differentiate between vehicles and pedestrians. Traffic light integration and warning sirens enhance site safety and traffic flow management.
Remote Control and Access Peripherals
Remote control transmitters and receivers facilitate wireless operation, with frequencies typically in the 433 MHz or 868 MHz range. Rolling code technology ensures secure communication preventing unauthorized duplication. Other access peripherals include RFID readers for vehicle tags, ANPR (Automatic Number Plate Recognition) cameras, and keypad entry systems, all integrating with the barrier gate's control board. These devices require careful consideration of their read range, encryption protocols, and environmental resilience for outdoor deployment.
