Description

Technical Field

[0001] The utility model relates to the technical field of logistics and transportation, and in particular to a peripheral centralized control device for an unmanned delivery vehicle. Background Art

[0002] With the rapid development of industrial automation and intelligentization, material handling using mobile robots (AGVs) / AMRs (Automated Automated Robots) has become a primary method in modern logistics and production lines. Currently, many AGV models use general-purpose controllers such as PLCs, combined with electrical control circuits (such as terminals / terminal blocks, power modules, and communication modules) to connect, wire, and control the AGV's peripheral electrical components. These systems collect and process signals from safety sensors, material sensors, position sensors, and control buttons, while also controlling the travel motors, actuator terminal motors, signal / status lights, slitters, and distributing power to various voltage levels.

[0003] Although these systems can meet engineering requirements in terms of functionality and effectiveness, they have some significant drawbacks. First, high component and manufacturing costs lead to a significant increase in overall costs. Second, system complexity increases and stability is insufficient, which may affect the reliability and safety of the AGV. In addition, these systems take up a large amount of space inside the AGV, which is usually limited. Finally, assembly and operation and maintenance personnel require a high level of technical skills, which increases dependence on professional technicians and limits the competitiveness of AGV products and corresponding logistics projects in the market and with customers. In addition, there are significant limitations in adding / expanding new functions, such as some communication functions, analog functions, and various sensors and output devices with different interfaces and voltage levels. Adding these functions and adapting new components will significantly increase the cost and difficulty. Utility Model Content
