Analyze the various components of the automatic barrier

Automatic barriers, also known as blockers, are widely used in highway toll gates, parking lots, residential areas, and entrances of enterprises and institutions to manage the entrance and exit of vehicles, including frequency conversion motors, boxes, travel control systems, integrated movements, and electrical control units. , torque balance mechanism and matching devices and other components. This article discusses these components separately.

Variable frequency motor: The speed of the motor can change with the input frequency, and the torque is constant when the speed changes greatly. When the power and the rotation speed are the same, compared with other common motors, the starting impulse current and the volume are the smallest, but the torque is 2 to 3 times that of other motors, and when the motor is locked for a long time, the operating current of the motor is not Will rise. As a result, the lift of the gate can be made very smooth, and the timing for opening (or closing) can be precisely controlled. The theoretical accuracy can reach 1/1000 second, and the motor will never be damaged in any case (excluding the use of overvoltage). .

Box: Pickling, phosphating, electrostatic spraying of polyester powder into a 295Â°C high temperature drying room, followed by two hours of hot melt and other surface treatment processes to obtain excellent weather resistance, scrub resistance, UV resistance, and no fading Performance.

Stroke control system: The coded positioning system and the above-mentioned self-encoded variable-frequency motor constitute a unique mechanism that bans all existing mechanical, optoelectronic, electromagnetic and other travel switches, so that the trip automatically learns, memorizes and repairs. There are no parts that need to be adjusted, maintained, and possibly damaged.

Integrated movement: The movement integrates the worm gear reducer, torque-changing mechanism, spindle support and main bracket into one. After 45# steel integral casting is formed by a large-scale CNC machining center, the number of internal parts is greatly reduced, and the overall reliability and batch quality consistency of the equipment are greatly improved.

Electric control unit: High reliability, highly integrated control system with microchip as the core. In addition to the internal integrated infrared encoder controller, airbag sensor controller, torque sensor, infrared radiation controller, ground-sensing controller, all-solid-state motor drive controller, gate position controller, power supply system and high-frequency head.

Moment balancing mechanism: Using a unique balancing mechanism, only one spring is used to easily balance the length of 1-6 meters of horizontal railings or articulated crank rails.

Optional equipment: pressure wave anti-smashing car device, remote control device, infrared detection protection device or ground detection protection device, ID/IC card intelligent parking management system and other configurations.
