A pedestrian gate is a traffic facility used to control pedestrian passage and vehicle flow. Depending on its structure and function, pedestrian gates can be categorized into various types, including electric gates, manual gates, and smart gates.

Types of pedestrian crossing gates:

1. Electric barrier gate

An electric barrier is a type of barrier powered by an electric motor, which controls the lifting and lowering of the gate rod via a remote control or automatic sensor. With advantages such as convenient operation and high automation, it is one of the widely used traffic facilities in modern urban traffic management.

2. Manual barrier gate

A manual barrier gate is a type of barrier gate powered by human effort, typically operated by a hand crank or chain to raise and lower the gate arm. It features a simple structure and low cost, but requires manual operation, making it suitable for specific locations and temporary traffic management.

3. Smart Barrier Gate

An intelligent barrier gate is a type of barrier gate integrated with smart devices such as sensors, controllers, and cameras, enabling automated control, license plate recognition, and facial recognition functions. It is suitable for high-level traffic management scenarios, such as highway toll stations and parking lots.

The working principle of the pedestrian crossing gate:

The basic working principle of a pedestrian crossing barrier involves utilizing a mechanical transmission system and control system to regulate the raising and lowering of the barrier arm and its stopping position. While different types of pedestrian crossing barriers may vary in structure and function, their operational principles are fundamentally based on similar mechanisms.

1. Mechanical transmission system

The mechanical transmission system of a pedestrian gate primarily consists of a motor, reducer, and chain. The motor serves as the core component that provides power, which is transmitted to the chain via the reducer, subsequently driving the gate arm to raise and lower. In electric gates, a braking device is typically installed to maintain stability during the gate arm's movement.

2. Control System

The control system of a pedestrian gate primarily consists of a controller, sensors, remote control, and other components. The controller serves as the core of the pedestrian gate control system, receiving signals from sensors and remote controls, and controlling the lifting and stopping positions of the gate based on preset programs. In some intelligent gates, the controller can also integrate with other smart devices such as facial recognition and license plate recognition systems to achieve higher-level automated control.

3. Safety Protection System

The safety protection system of the pedestrian crossing barrier primarily consists of a collision prevention device and photoelectric switches. The collision prevention device prevents the barrier arm from colliding with vehicles or pedestrians during its lifting and lowering process, while the photoelectric switches detect the passage of pedestrians or vehicles to avoid causing harm during the barrier's movement.

4. Smart Device Interconnection System

Some intelligent barriers are equipped with smart device interconnection systems, enabling coordination and information exchange with other smart devices. For instance, they can be linked with parking management systems for automated charging and management, or integrated with surveillance cameras for real-time monitoring and security prevention.
