In the context of the rapid development of the logistics industry today, the application of automation technology has become the key to improving efficiency and competitiveness.
The application of the DEKWELL EX series card-type remote I/O in cross-belt sorting systems has brought innovation and breakthroughs to the industry by solving problems such as signal transmission and control system complexity on-site.
1. Industry Analysis
Cross-belt sorting systems, with their unique advantages, are widely used in numerous industries such as e-commerce, express delivery, airports, and distribution centers. They can efficiently and accurately handle various small items, meeting the market's demand for rapid sorting. With technological advancements and market expansion, cross-belt sorting systems are playing an increasingly important role in the field of automated logistics.
It mainly includes a feeding system, a sorting host system, information identification, a motion control system, an unloading system, a control system, a sorting port, and an indicator system.
2. Pain points on site
During the operation of cross-belt sorting systems, challenges often arise in signal acquisition and transmission, which can affect sorting accuracy and efficiency, and increase operating costs and management difficulty.
Pain Point 1: Signal Interference
In complex logistics environments, electromagnetic interference can cause signal distortion or loss, affecting the accuracy of data.
The Dekwell EX module boasts Class A EMC protection, providing strong anti-interference capabilities and effectively resisting external electromagnetic interference to ensure signal accuracy and stability. It remains stable even under electromagnetic interference environments generated by motors, frequency converters, and other equipment in cross-belt sorting systems.
Pain Point 2: Difficulty in Synchronizing Signal Acquisition
The sorting system involves numerous conveyors and sorting ports, and signal acquisition needs to be synchronized across different nodes; otherwise, sorting errors will occur.
The EX series card-type remote I/O can comprehensively ensure the stable and synchronous transmission of field signals:
1. Supports multiple communication protocols to ensure efficient communication with various master station devices, reduce signal transmission problems caused by protocol incompatibility, and achieve stable data interaction.
2. Supports multiple signal types, and can connect to various different devices in cross-belt sorting systems, such as position sensors, speed sensors, cylinders, etc., to fully meet the system's signal acquisition requirements.
3. The use of plug-in terminals and tool-free installation not only simplifies the installation process and improves installation efficiency, but also reduces signal transmission failures caused by loose wiring.
4. Fast response speed, with a response time of 5~10ms, it can collect and transmit field signals in a timely manner, meeting the real-time requirements of application scenarios such as cross-belt sorting systems, and improving the overall operating efficiency of the system.
5. It possesses efficient diagnostic functions, enabling real-time monitoring of the signal acquisition and transmission process. When signal abnormalities or faults occur, it can quickly locate the problem, facilitating timely troubleshooting and repair by maintenance personnel, reducing the impact of faults on system operation, and improving system reliability and maintainability.
Pain Point 3: Signal Attenuation
When transmitting signals over long distances, signal attenuation may occur, leading to a decrease in signal quality.
The DEKWELL EX series modules adopt a distributed installation method, which can distribute multiple remote I/O modules near the signal source or actuator, reducing signal transmission distance and reducing the risk of signal attenuation. At the same time, the modules are small in size, making them easy to install and lay out in the space-constrained cross-belt sorting system without taking up too much space, and facilitating integration with other equipment.
3. The Deckerwell Plan
In this cross-belt sorting project, an industrial computer is used to establish communication with the EX series I/O via a self-developed control system using the Modbus TCP protocol. This allows the computer to collect signals from each conveyor and interact with the host computer to control the various actions of the cross-belt sorter.
