How AGVs Maintain High Safety During Automatic Operation

 Efficient and low-cost material transportation is a significant measure for many manufacturing plants and warehouses to improve operations. AGVs can achieve efficient and low-cost material transportation, and in terms of safety, AGVs are very safe compared to other material transportation methods, especially when compared to manual handling.

 

 

How is such high safety achieved by AGVs? Below, we will explain that AGVs are equipped with many safety devices to prevent accidents, such as flashing lights, audio devices, physical emergency bumpers, infrared sensors, and ultrasonic devices.

 

How to avoid collisions between AGVs running on the same path? This involves traffic control. For example, a flexible manufacturing system with multiple AGVs requires traffic control to ensure that AGVs do not collide with each other. Traffic control can be executed locally on the AGVs or through software on a fixed computer elsewhere in the factory

 

 

1. Zone Control

 

Zone control is the most preferred method in most environments because it is simple to install and easy to expand. Zone control uses wireless transmitters to send signals within a fixed area. Each AGV contains a sensor to receive the signal and respond to the transmitter. If a zone is empty, the signal is set to "clear," allowing any AGV to enter and pass through the zone. If an AGV is in the zone, a "stop" signal is sent, and all AGVs attempting to enter the zone will stop and wait for their turn.

 

Once the AGV in the zone has moved out, a "clear" signal is immediately sent to one of the waiting AGVs. Another way to establish zone control traffic management is to equip each robot with its own small transmitter/receiver. Each AGV sends its own "do not enter" message to all AGVs approaching its spatial area. A problem with this method is that if a zone fails, all AGVs are at risk of colliding with each other. Zone control is a low-cost and effective method for managing AGVs in specific areas.

 

 

2. Sensor Control

 

Sensor control uses obstacle avoidance sensors to prevent collisions with other AGVs in the area. Sensors include ultrasonic sensors, which work similarly to radar; optical sensors, which use infrared sensors; and bumpers, which are physical contact sensors. Most AGVs are equipped with some form of bumper sensor as a fail-safe. Ultrasonic sensors emit chirps or high-frequency signals and then wait for a response. The AGV determines whether there is an object ahead by analyzing the response signal and takes necessary actions to avoid collisions. Optical sensors use infrared transmitters/receivers to emit an infrared signal, which is then reflected back, operating on a similar concept to ultrasonic sensors. The issue with these methods is that they can only protect the AGV within a limited angle.

 

 

3. Integrated Control

 

Integrated control combines collision avoidance sensors and zone control sensors. The combination of the two helps prevent collisions in any situation. Under normal operating conditions, zone control is used, while obstacle avoidance serves as a fail-safe. For example, if the zone control system fails, the obstacle avoidance system will protect the AGV from collisions.

 

Integrated control combines sensor control and zone control to manage traffic between AGVs. Each AGV in the system is equipped with two infrared obstacle avoidance sensors: one at the front to detect obstacles ahead and another at the front-right to detect oncoming vehicles from the side. For added safety, the system also uses zone control. The dispatch center sets a mutual exclusion signal in areas where collisions are likely to occur. When an AGV enters the area, it occupies the mutual exclusion signal, and the dispatch center sends a stop signal to other AGVs attempting to enter the area. Once the first AGV leaves the area, the mutual exclusion signal is released, allowing the next AGV to enter.

 

 

AGVs are not only a key technology in modern logistics and manufacturing but also a symbol of technological advancement for enterprises. They enhance production efficiency, reduce labor costs, enable refined management, and increase logistics flexibility. With continuous technological development and innovation, AGVs are expected to play a broader role in more fields, bringing greater value to enterprises and industries. Let us look forward to the surprises and transformations that AGVs will bring in the future!

What is the difference between AGV and LGV?

 

Understanding the Core Differences Between AGV and LGV

When selecting the right automated material handling system, many businesses face the choice between Automated Guided Vehicles (AGVs) and Laser-Guided Vehicles (LGVs). Both technologies are pivotal in modern warehouses and factories, but understanding the differences can help make the right decision for specific operational needs.

AGV: Overview and Applications

AGVs are unmanned vehicles designed to transport materials and goods throughout a facility. They use various guidance systems, such as magnetic strips, wires, or sensors embedded in the floor, to navigate predefined paths. This makes AGVs particularly useful in industries that have repetitive tasks with fixed routes, such as manufacturing or logistics facilities.

Common Uses of AGVs

• Transporting raw materials in production plants.

• Moving products in warehouses with fixed storage zones.

• Repetitive tasks such as loading and unloading cargo.

AGVs are widely recognized for their flexibility in layouts and ability to easily integrate into existing operations without significant infrastructure changes.

LGV: An Evolution of AGVs

LGVs are a specialized subset of AGVs that use laser-guided technology for navigation. Instead of following physical lines or magnetic tracks, LGVs use reflective strips placed throughout the facility. The laser system on the vehicle detects these reflectors to guide its movements with high precision.

Key Advantages of LGVs

• Flexibility in route changes without needing to modify the facility’s floor layout.

• Improved accuracy in navigation, especially in environments where obstacles or layout changes occur frequently.

• Efficient in large, complex environments with varying paths and destinations.

LGVs are more adaptable than traditional AGVs, especially in dynamic settings where routes or storage zones may change frequently. This advanced guidance system makes them ideal for larger, high-traffic facilities where flexibility is paramount.

Cost and Scalability Considerations

The cost difference between AGVs and LGVs primarily stems from the guidance system. AGVs tend to have a lower upfront cost because they use simpler, more fixed guidance methods. However, they require changes in the facility layout for each new route. On the other hand, LGVs, although more expensive upfront, offer better scalability as they don’t require physical modifications to the environment when routes change.

Which One Should You Choose?

For facilities with predictable, repetitive tasks and a fixed layout, AGVs can be an excellent cost-effective option. They are well-suited for operations where scalability is not a major concern, and changes to the environment are minimal. However, for larger operations, or industries with frequent layout changes or variable tasks, LGVs provide better flexibility, precision, and long-term scalability, despite the higher initial cost.

Maintenance and Reliability

Both AGVs and LGVs require regular maintenance, but the type of maintenance differs based on the guidance system. AGVs, which rely on physical tracks or wires, may experience more wear and tear due to interactions with these elements. Conversely, AGV Pallet Trucks, which use laser guidance, typically require less physical maintenance as there is no direct contact with the guidance infrastructure. However, ensuring the reflectors are clean and correctly positioned is crucial for optimal performance.

Conclusion: Making the Right Choice

The decision between AGVs and LGVs depends largely on the operational needs of your facility. If you're running a smaller operation with minimal variability, AGVs may be the right choice for their cost-efficiency. However, for larger, more dynamic environments, LGVs offer greater flexibility, precision, and scalability, making them a better investment in the long run.

What are the pain points of electric forklifts?

 As an important equipment in the field of modern logistics and warehousing, electric forklifts have the advantages of environmental protection, no emissions, and low noise compared to traditional internal combustion forklifts. However, there are also some pain points in the use and development of electric forklifts:

Limitations of charging infrastructure: Specialized charging stations need to be established and maintained. For warehouses or factories that use a large number of forklifts, this may be a significant initial investment.

Adaptability and diversity issues: Electric forklifts may not perform as well as internal combustion forklifts in extreme weather conditions (especially extremely low temperatures). In addition, the adaptability of electric forklifts in handling overweight loads or in special working environments may also be a problem.

Technical and standardization issues: The technical standards of the Electric Stacker industry have not yet been fully unified, which may lead to compatibility issues, such as batteries and charging facilities of different brands may not be universal.

Analysts at Forklift.com said that despite these pain points, the development prospects of electric forklifts are still widely optimistic:

Environmental regulations and policy support: With the global emphasis on reducing carbon emissions and pollution, more and more countries and regions are implementing strict environmental regulations to encourage or force the use of electric forklifts.

Technological progress: The continuous progress of battery technology (especially lithium batteries) is gradually solving the problems of battery life and life. At the same time, innovations in charging technology (such as fast charging, battery swap stations, etc.) are also improving the efficiency of electric forklifts.

Reduction in operating costs: In the long run, the maintenance cost and energy cost of electric forklifts are lower than those of internal combustion forklifts, which makes electric forklifts competitive in terms of total life cycle cost.

Social responsibility and brand image: Using electric forklifts can help companies enhance their environmental image and meet the requirements of consumers and partners for sustainable development.

Overall, despite many challenges, the development prospects of electric AGVS are positive, driven by technological progress, policy support and market demand, and its market share is expected to continue to grow.
