Description

Self-adaptive embedded printing system of flexible circuit and modularized design printer Technical Field The invention belongs to the technical field of computer control and embedded systems, and particularly relates to a self-adaptive embedded printing system of a flexible circuit and a modularized design printer. Background As core equipment for intelligent manufacturing and personalized production, embedded printing systems have been widely used in recent years in the fields of industrial automation, consumer electronics, medical health, and the like. The system realizes the printing job capability with high precision, small volume and low power consumption by deeply integrating the printing control module, the driving circuit and the mechanical structure. Along with the continuous expansion of application scenes, higher requirements are put forward on the environmental adaptability, maintainability and function expansion capability of a printing system, and particularly under the scene of limited space or complex working conditions, the design of a traditional rigid circuit and a fixed framework is difficult to meet diversified requirements. Among them, printers employing flexible circuit technology and modular design concepts are an important research direction for improving system flexibility. The flexible circuit gives the printing system the ability to stably transmit signals and power under bending, folding or dynamic deformation conditions, while the modular design supports the rapid replacement and reconstruction of functional units, significantly enhancing the configurability and maintenance efficiency of the device. The combination of the two provides a technical foundation for developing the lightweight and high-adaptability embedded printing device, and gradually becomes the development trend of the next-generation intelligent printing terminal. In the prior art, although some printing systems attempt to introduce flexible circuit wiring or modular components, there is still a problem of insufficient system level integration. The layout of the flexible circuit is not optimized in cooperation with the thermal management and electromagnetic compatibility among the modules, so that the long-term operation reliability is reduced, the interface standard among the functional modules is not uniform, the implementation degree of plug and play is restricted, the control system lacks the self-identification and parameter self-setting capability for the topology change of hardware, the module is required to be reconfigured manually after being replaced, and the real self-adaptive operation cannot be realized. In addition, in an embedded environment with limited resources, how to balance real-time performance, power consumption and computational load still constitutes a key bottleneck affecting the response speed and printing quality of the system. Therefore, it is desirable to construct an adaptive embedded printing system that deeply fuses the characteristics of a flexible circuit and the advantages of a modular architecture, so as to solve the above technical problems.

The traditional printer generally adopts a rigid circuit board and a fixed functional module framework, the hardware function of the traditional printer is locked after leaving the factory, the printing capability is difficult to dynamically adjust according to a user scene, meanwhile, the traditional rigid structure cannot realize curved surface fitting and dynamic deformation adaptation to cause the reduction of printing precision and even equipment damage in the face of the new printing requirements of increasingly-growing special-shaped labels, flexible packages, wearable electronics and the like, and in addition, when a certain functional module fails, the whole printer often needs to be stopped for maintenance, the system availability is low, and the operation and maintenance response period is long. The technical scheme of the invention is that a modularized printer system driven by a self-adaptive embedded control core and based on flexible circuit interconnection is constructed, and the system has the capabilities of physical structure reconfiguration, electrical connection self-identification and function configuration dynamic loading. The system integrally comprises a main control processing unit, a flexible circuit transmission network, a plurality of function execution modules, a mechanical coupling interface array and an environment sensing group. The main control processing unit is deployed at the central position of the equip
