AGV Cart Full-Duplex Communication Application – Low Latency, 8-Channel Concurrent Full-Duplex Communication

With the continuous development of intelligent manufacturing and the logistics industry, AGV carts (Automated Guided Vehicles) are increasingly being used in factories, warehouses, and logistics centers. AGV carts, with their automation, efficiency, and flexibility, are gradually becoming key equipment in material handling. In such complex and dynamic environments, the reliability, real-time performance, and anti-interference capability of data transmission are crucial.

AGV Characteristics and Data Communication Requirements

AGV carts typically perform material handling tasks in complex factory or warehouse environments. They require real-time data exchange with central control systems or other devices via wireless communication to ensure real-time updates for path planning, task scheduling, and environmental awareness. In this process, the quality of communication directly impacts the efficiency and safety of AGV operations. Traditional half-duplex communication, which requires taking turns to send and receive data, may lead to transmission delays, especially when multiple AGVs are working simultaneously. This increases the likelihood of data collisions and retransmissions, potentially affecting the overall system's stability. Therefore, introducing full-duplex communication technology is essential for optimizing AGV system performance.

Full-duplex communication allows AGV carts to send and receive data simultaneously, significantly reducing communication delays and ensuring real-time command execution and task responsiveness. In complex environments where multiple AGVs operate in parallel, full-duplex communication helps avoid data collision issues common in traditional half-duplex systems, greatly reducing the need for data retransmission and enhancing system stability and reliability.

Additionally, full-duplex communication supports high-frequency, low-latency data interaction between AGVs and central control systems or other devices, which is crucial for dynamic adjustments in path planning, real-time task status feedback, and precise transmission of environmental awareness data. In factories or warehouses, real-time responsiveness is key to ensuring safety. Full-duplex communication ensures that AGVs can efficiently and accurately execute tasks in complex environments, effectively reducing the risk of collisions and accidents.

Application of Full-Duplex Communication in AGV Carts

The SA618F30-FD is a highly integrated, high-power 8-channel full-duplex data transmission module, supporting dynamic changes among 8 parties. The module is equipped with electrostatic protection (ESD) and supports OTA and serial port upgrades. In terms of transmission performance, it features low latency, high reception sensitivity, and a transmission range of 3 to 4 kilometers in open areas, making it ideal for large-scale full-duplex applications such as multi-AGV cart systems.

The full-duplex capability of the SA618F30-FD module enables AGV carts to send and receive data simultaneously during communication, providing robust support for efficient and safe operation of multiple AGVs in the same working environment. Beyond just two-way full-duplex communication, the SA618F30-FD offers the following additional advantages:

Low Latency:Full-duplex communication eliminates the wait time for switching between sending and receiving data, reducing latency to 50ms, greatly enhancing real-time response efficiency. In the application of AGV carts, this significantly improves their real-time responsiveness, ensuring that the carts can quickly receive and execute commands from the central control system in complex environments. This fast data transmission enables AGVs to promptly adjust their paths, avoid obstacles, and dynamically allocate tasks, reducing operational errors caused by communication delays. Additionally, low latency effectively enhances the efficiency of multiple AGVs working together, preventing conflicts and delays in task scheduling, thereby improving the overall system's operational efficiency and safety.

 Simultaneous Multi-Device Communication:The SA618F30-FD supports up to 8 transmitting devices communicating simultaneously without interference. This is crucial for multiple AGVs working together in the same environment. With multiple AGVs able to communicate with the central system at the same time without having to take turns, the system's concurrent processing capability is greatly improved, ensuring the efficiency of task scheduling.

Support for ESD Protection:The module supports electrostatic discharge (ESD) protection, preventing system malfunctions and enhancing safety. It provides protection against system crashes, reverse polarity, and overvoltage. This feature ensures a more reliable AGV system in factory and warehouse environments.

Long-Distance Transmission:With a high reception sensitivity of -117 dBm, the SA618F30-FD module enables long-distance wireless communication, covering up to 3-4 kilometers in open areas. This is a significant advantage for AGV systems that need to operate across large factories or logistics centers. Stable long-distance transmission reduces the need for dense deployment of communication base stations, lowering overall system costs.

Low Power Consumption Design:The SA618F30-FD adopts a low-power design in both receive and sleep modes, which is essential for AGV carts. Low power consumption extends the AGV's operational time, reducing the need for frequent recharging and improving overall efficiency.

Highly Integrated and Compact for Easy Embedding:The SA618F30-FD module'shigh integration and compact design make it easy to embed directly into AGV carts. This provides manufacturers with more design flexibility, allowing for better optimization of the cart's structure and improving the overall performance of the end product.

Support for OTA and Serial Upgrades:The module also supports Over-the-Air (OTA) and serial upgrades, ensuring that AGV carts can quickly and conveniently update firmware or adjust parameters during operation without the need to shut down and disassemble equipment. This feature significantly enhances the system's maintenance efficiency.
