Barrier systems are devices used to control vehicle access in parking lots. When a vehicle enters or exits, the barrier automatically raises and lowers after the vehicle leaves. However, due to substandard technology, some barriers on the market fail to identify vehicles or pedestrians passing through them, or are unable to do so in time. This can lead to the barrier striking vehicles or pedestrians, causing damage and injury. Consequently, there is increasing attention being paid to the safety of parking lot barrier systems and their anti-smashing technologies. Today, we will discuss several anti-smashing technologies for barrier systems.
1. Infrared Anti-Smashing
Infrared anti-smashing technology involves installing infrared beams on both sides of the entry and exit barriers. If a vehicle enters during the barrier's lowering process, the infrared beam is blocked, causing the barrier to automatically raise. However, this technology has a limited infrared range and is easily affected by rain or snow.
2. Pressure Wave Anti-Smash Technology
Pressure wave anti-smash technology is also known as resistance anti-smash technology. When a parking lot barrier is equipped with an resistance return device, if the barrier arm encounters a vehicle or pedestrian during its descent, the rubber strip on the barrier arm experiences resistance. The intelligent resistance return device then switches the barrier arm from the down position to the up position, raising the barrier.
3. Ground Sensor Anti-Smash Technology
Parking lots are generally equipped with ground sensors. When a vehicle detector detects a signal from the ground sensor, the barrier arm rises. When the ground sensor signal disappears, the barrier arm falls. The key to this ground sensor anti-smash technology lies in the stability of the ground sensor coil. External interference with the ground sensor can cause it to malfunction. Furthermore, the ground sensor can only detect vehicles and does not protect against pedestrians.
