Description

New energy street lamp full-flexible production line based on multiple robots Technical Field The invention relates to the technical field of automatic production, in particular to a new energy street lamp full-flexible production line based on multiple robots. Background In the technical field of automatic production, particularly for products with multiple specifications and customized requirements such as new energy street lamps, a flexible production line is a key for realizing efficient manufacturing. Existing flexible manufacturing lines typically rely on a central control system, such as a Manufacturing Execution System (MES), to uniformly plan, schedule, and assign production tasks to various automated equipment on the line, such as robots or automated guided vehicles. However, such highly centralized control architecture is increasingly subject to its inherent technical drawbacks when dealing with highly dynamic and personalized production needs. The central control system needs to process the real-time state of all the devices and conduct global path and task planning, which is very easy to form calculation and communication bottlenecks, and results in response delay of the system when facing sudden working conditions or frequent order change, so that the real flexibility and self-adaption capability of the production line are limited. In order to overcome the above limitation of centralized control, the industry has sought a more distributed control architecture, which gives the production units some autonomous decision-making ability. But this in turn introduces new technical challenges, namely how to ensure operational safety and overall reliability of the system in a distributed environment. When the production unit can make an autonomous decision, how to effectively prevent unauthorized key operation caused by interception of communication or decision errors of the unit itself becomes a technical problem to be solved. It is difficult to completely circumvent the risk of physical execution level by relying only on authentication or instruction encryption at the software level. Furthermore, the prior art is also deficient when multiple robots cooperatively perform complex tasks. For example, when performing high-precision cooperative assembly tasks, each robot mainly relies on its own vision sensor and attitude synchronization through network communication, which is susceptible to network delays and sensor errors, limiting the final cooperative precision. When high-energy-consumption tasks such as laser welding are executed, the energy supply system is generally global, dynamic and accurate power allocation is difficult to carry out according to local and instantaneous task demands, so that the energy utilization efficiency is reduced, and the bearing capacity of a production line on complex tasks is limited. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a full-flexible production line of a new energy street lamp based on multiple robots, which solves the problems of communication bottleneck, response delay and insufficient system robustness caused by relying on centralized control when the flexible production line faces to highly dynamic and personalized production tasks in the prior art. The novel energy street lamp full-flexible production line based on the multiple robots comprises at least one product information body, a modularized intelligent production platform and at least one intelligent production unit. The product information body is used for bearing a product to be processed and comprises a distributed digital file and a first communication module. The distributed digital archive is used for recording and updating the state information of the product information body. The status information indicates the currently required production operation of the product to be processed. The first communication module is used for outputting a state signal to the outside according to the current state information. The modular intelligent production platform is the physical foundation that carries the product information body and the intelligent production unit. The inside of the wireless energy transmission module comprises a wireless energy transmission module and a second communication module. The second communication module is configured to receive the status signal from the product information body. The wireless energy transfer module generates a modulated wireless energy field upon receiving the status signal. The modulated wireless energy field has its physical characteristics modulated by the state information, thereby carrying the state information itself. The intelligent production unit is located above the modularized intelligent production platform. The device comprises an energy receiving module, a state decoding module, an operation executing module and a third communication module. The energy receiving module continuously receives the modula
