How does the bidirectional parallel automatic escalator change the pattern of building traffic? ​

The working principle of the bidirectional parallel automatic escalator​
As the name suggests, the bidirectional parallel automatic escalator is an escalator system that can transport passengers in two directions at the same time. Its core structure is based on the principle of traditional escalators. The motor drives the chain to drive a series of steps to circulate. In the bidirectional parallel automatic escalator, two sets of steps are arranged in parallel, one set runs upward and the other runs downward, like two parallel moving channels, which do not interfere with each other but work closely together. ​
As the power source of the entire system, the motor provides continuous and stable power for the operation of the escalator. Through the reduction device, the high-speed rotational motion output by the motor is converted into a low-speed, high-torque motion suitable for the operation of the steps. The chain is like the skeleton of the human body, transmitting power to each step to ensure that they move smoothly according to the predetermined track. During the operation of the steps, the handrail belt runs synchronously with the steps to provide reliable support and guidance for passengers to prevent accidents. ​
In order to ensure the safe and stable operation of the bidirectional parallel automatic escalator, it is also equipped with a series of sophisticated control systems. These systems can monitor the operating status of escalators in real time, including parameters such as speed, direction, and load. Once an abnormal situation is detected, such as step jamming, overspeeding, or overloading, the control system will immediately trigger the safety protection device to automatically stop the escalator to avoid accidents. ​
Application scenarios of bidirectional parallel escalators ​

Advantages of bidirectional parallel escalators​
Efficient transportation capacity​
Bidirectional parallel escalators can realize passenger transportation in two directions at the same time, greatly improving transportation efficiency. In the same time, the number of passengers that can be transported by bidirectional parallel escalators is twice or even more than that of one-way escalators, which is of vital importance for places with large personnel flow, such as shopping centers, transportation hubs, etc. It can effectively alleviate congestion, reduce passengers' waiting time, and ensure the rapid evacuation and flow of personnel.​
Save space​
Compared with traditional one-way escalators, the parallel arrangement of two-way parallel escalators can achieve greater transportation capacity while occupying the same building area. This means that in architectural design, precious space resources can be saved by adopting two-way parallel escalators, providing more possibilities for the setting of other functional areas. At the same time, the parallel arrangement of steps also makes the appearance of the escalator more concise and neat, which is in line with the aesthetic concept of modern architecture. ​
Improve user experience​
Two-way parallel escalators provide users with a more convenient and comfortable travel experience. Passengers no longer need to choose the up or down escalator according to their direction of travel like using one-way escalators, but can easily choose the direction they need at the same location, greatly reducing the inconvenience and confusion of travel. At the same time, the synchronous operation of the handrail and the steps and the smooth operation mechanism also provide passengers with reliable safety protection, making them feel more at ease and comfortable when riding the escalator. ​
Flexible design options​
Two-way parallel escalators have strong design flexibility and can be customized according to the spatial layout and functional requirements of different buildings. Its parameters such as slope, step width, and running speed can be adjusted according to actual conditions to adapt to the flow of people and usage requirements of different places. In addition, the appearance design of the two-way parallel escalator can also be integrated with the overall style of the building. By using different materials, colors and shapes, a unique visual effect can be created, adding a unique charm to the building. ​
Technical development of two-way parallel escalators ​
Application of energy-saving technology ​
Today, as energy issues are becoming increasingly prominent, energy conservation has become one of the important directions for the development of two-way parallel escalator technology. In order to reduce energy consumption and reduce the impact on the environment, more and more two-way parallel escalators have adopted advanced energy-saving technologies. For example, the frequency conversion drive system is used to automatically adjust the motor speed according to the actual load of the escalator, and the running speed is reduced when the passenger flow is small, thereby reducing energy consumption; using high-efficiency and energy-saving motors and lighting systems to improve energy utilization efficiency; using intelligent control systems to realize the automatic start and stop of the escalator to avoid idling waste when no one is using it. ​
Intelligent monitoring and management ​
The application of intelligent technology has brought revolutionary changes to the monitoring and management of two-way parallel escalators. Through the sensors and intelligent monitoring equipment installed in various parts of the escalator, the operation data of the escalator can be collected in real time, including speed, temperature, vibration, load and other parameters, and these data can be transmitted to the central control system for analysis and processing. Once an abnormal situation is found in the escalator, the control system can immediately issue an alarm, and quickly locate the cause of the fault through remote diagnosis technology, and provide accurate maintenance guidance for maintenance personnel. At the same time, the intelligent monitoring system can also analyze the operation history data of the escalator, predict the risk of equipment failure, arrange maintenance work in advance, and improve the reliability and service life of the equipment. ​
Upgrade of safety technology ​
Safety has always been the top priority of the development of bidirectional parallel escalator technology. In order to ensure the safety of passengers, bidirectional parallel escalators have made a lot of innovations and upgrades in safety technology in recent years. In addition to traditional safety protection devices, such as handrail entrance protection devices, step chain break protection devices, overspeed protection devices, etc., some new safety functions have also been added. For example, light curtain protection technology is adopted, and light curtain sensors are set at the entrance and exit of the escalator. When an object blocks the light curtain, the escalator will stop running immediately to prevent passengers from being pinched; an inclination detection device is installed to monitor the inclination angle of the escalator in real time, and measures are taken immediately once an abnormality is found to ensure the smooth operation of the escalator; an emergency braking system is introduced. In case of an emergency, passengers can press the emergency brake button to quickly stop the escalator and avoid accidents. ​
Application of new materials​
The continuous emergence of new materials has brought more possibilities for the design and manufacture of bidirectional parallel escalators. In terms of the structural components of the escalator, the use of high-strength and lightweight materials such as aluminum alloy and carbon fiber composite materials can not only reduce the weight of the escalator and reduce energy consumption, but also improve the load-bearing capacity and operation stability of the escalator. In the manufacture of steps and handrails, new materials that are wear-resistant, anti-slip and fire-resistant are used to improve their service life and safety. In addition, some materials with self-cleaning and antibacterial functions have also begun to be used in the surface decoration of escalators to provide passengers with a more hygienic and comfortable riding environment.​
Safety considerations for two-way parallel escalators

Passengers' own safety awareness is one of the key factors to ensure riding safety. Therefore, it is necessary to strengthen safety education for passengers through various channels to improve their safety awareness and self-protection ability. Clear and clear safety reminder signs should be set up at the entrances and exits of escalators and in conspicuous locations to inform passengers of the correct riding methods and precautions, such as standing firmly and holding on, not running and playing on escalators, and not carrying oversized or heavy items. At the same time, the broadcasting systems and electronic display screens in shopping malls, transportation hubs and other places are used to play safety publicity videos and reminder information in a loop to deepen passengers' impression of safety knowledge. ​
Daily maintenance and care
Regular and professional maintenance is an important guarantee to ensure the safe and reliable operation of two-way parallel escalators. Maintenance work should include comprehensive inspection, cleaning, lubrication, adjustment and repair of the mechanical parts, electrical systems, safety protection devices, etc. of the escalator. Maintenance personnel should have professional skills and qualifications, strictly follow the operating procedures and maintenance standards to work, and promptly discover and eliminate potential safety hazards. In addition, a complete maintenance record file should be established to record the time, content, problems found and handling results of each maintenance in detail for traceability and analysis. ​
Emergency rescue plan formulation and drills​
In order to deal with possible sudden safety accidents, such as escalator failures and passengers trapped, a scientific and reasonable emergency rescue plan must be formulated. The emergency rescue plan should clarify the organization, division of responsibilities, response procedures, rescue methods and precautions of emergency rescue, and regularly organize relevant personnel to conduct drills to ensure that rescue work can be carried out quickly and effectively when an accident occurs, minimizing casualties and property losses. Emergency rescue equipment and materials should be fully equipped, and regularly inspected and maintained to ensure that they are in good standby condition. ​
