As an important part of traffic control equipment, the development of the barrier has gone through several stages along with the advancement of technology and changes in application needs. The following is the main development process of the barrier:
1. Mechanical barrier stage
The barrier originated from a purely mechanical design and mainly relied on manual operation. Early barriers were usually used in railways or smaller traffic checkpoints, using levers or manual shaking devices to raise and lower the barrier poles. The operation required manpower, was inefficient, and was easily affected by human factors.
2. Motor barrier stage
With the development of electric technology, the barrier gradually introduced motor drive, and electric barriers began to appear. The motor replaced manual operation and used electricity to drive the barrier pole up and down. The barrier at this stage mainly used AC motors. Although the efficiency was improved, the speed and control accuracy of the motor were limited, and the overall system was relatively bulky.
3. Intelligent control stage
With the development of electronic technology, especially the development of microprocessors and control circuits, the barrier system has entered the intelligent control stage. The intelligent barrier system integrates automatic control, sensors, and wireless communication technologies, so that the barrier can not only be automatically raised and lowered, but also cooperate with vehicle detectors, remote control and other equipment to achieve unmanned management. At this stage, barriers began to be widely used in parking lots, residential areas, shopping malls and other places.
4. Brushless DC Motor Barrier Stage
In recent years, barrier technology has entered the brushless DC motor (BLDC) stage. The introduction of this motor has greatly improved the efficiency and stability of the barrier system. Compared with traditional AC motors, brushless DC motors are more efficient, run more smoothly, have lower noise and longer service life. In addition, brushless DC motors also allow more precise speed control and torque output, making the barrier rise and fall smoother and more responsive.
5. Intelligent networking and cloud control stage
With the development of Internet of Things (IoT) technology, modern barrier systems are increasingly integrating networking functions. Through the network, the barrier can be connected to the central control system and the cloud platform to provide remote monitoring, data analysis, real-time feedback and other functions. For example, the parking lot management system can monitor the parking spaces in real time, manage charges, and perform data statistics through the networked barrier system.
6. Multi-function integration stage
Currently, many barrier systems are not limited to simple vehicle traffic control, but also integrate more functions. For example, technologies such as automatic license plate recognition, QR code scanning, and automatic payment have made the barrier gate more diversified. The barrier gate is no longer just a simple traffic management device, but has become more of a part of smart transportation and smart cities, serving complex applications such as parking management and traffic flow control.
Summary:
The development history of the barrier gate reflects the technological evolution from manual mechanical to intelligent, networked, and integrated. In the future, with the continuous advancement of technologies such as the Internet of Things and artificial intelligence, the barrier gate system is expected to further improve its intelligence level and become a more important part of traffic management and urban management.
