In the process of digital transformation of smart factories, machining centers, as the core production equipment, are upgrading their operation and maintenance mode from traditional on-site operation to remote intelligent operation and maintenance. The interconnection between the lock code panel of the machining center and the remote operation and maintenance system is a key node in achieving this upgrade. By breaking the local operation limitations of the lock code panel and building a "local control+remote collaboration" operation and maintenance system, it not only improves the flexibility of parameter management and permission control, but also realizes the intelligence of fault warning and remote diagnosis, providing core support for the efficient production of smart factories. The core logic of its interconnection practice lies in "data interoperability, controllable permissions, and collaborative operation and maintenance". Through standardized interconnection architecture and functional adaptation, it unleashes the value of digital operation and maintenance.
The establishment of standardized interconnection architecture is a fundamental prerequisite for practice. The interconnection system mainly consists of four parts: lock code panel terminal, communication module, edge gateway, and remote operation and maintenance platform. The locking panel of the machining center is connected to the edge gateway by installing an industrial Ethernet module or wireless communication module; The edge gateway is responsible for data collection, protocol conversion, and local caching functions. It converts the parameter data, operation logs, fault information, etc. of the lock code panel from device private protocols to standardized industrial communication protocols, ensuring that data can be transmitted across systems; The remote operation and maintenance platform achieves centralized interconnection with multiple processing center lock panels through cloud servers, building a three-layer architecture of "terminal gateway cloud" to ensure the stability and security of data transmission. At the same time, an encrypted transmission module is embedded in the architecture to encrypt sensitive data (such as encryption parameters and permission information) of the lock code panel end-to-end, preventing the risk of data leakage.
The implementation of core interconnection functions is the embodiment of the core value of practice. In terms of remote parameter control, operation and maintenance personnel can access the parameter configuration of the lock code panel of each machining center in real time through the remote platform, and remotely issue and calibrate parameters for batch production needs, avoiding the tedious on-site operation of each device and improving the efficiency of parameter adjustment; In terms of remote management of permissions, the platform supports remote configuration and dynamic adjustment of hierarchical permissions. It can remotely open or revoke the operation permissions of lock code panels for different positions according to production task requirements, and record permission operation logs to achieve traceability of permission control. In terms of remote fault diagnosis, when there are problems such as poor contact or abnormal parameters on the lock code panel, the system can collect fault codes and operating data in real time, push them to the remote platform, and trigger an alarm. The operation and maintenance personnel can analyze the cause of the fault remotely through the platform, guide on-site personnel to handle it accurately, or directly reset and repair simple faults through remote instructions, shortening the downtime of the fault.
The key points of Internet practice lie in compatibility and operational collaboration. In terms of compatibility and adaptation, it is necessary to ensure that the communication module of the lock code panel is compatible with the CNC system of the machining center to avoid signal interference; At the same time, the remote operation and maintenance platform needs to support the access of lock code panels for multiple brands and models of machining centers, and adapt to the protocol differences of different devices through standardized interfaces. In terms of operation and maintenance collaboration, a linkage mechanism of "remote warning on-site disposal" will be established. The remote platform will monitor the operation status of the lock code panel in real time, identify potential risks such as parameter drift and line aging in advance, and push warning information to relevant personnel; On site personnel receive warnings and disposal guidance through mobile terminals, cooperate with remote operation and maintenance to complete fault diagnosis, and form a collaborative closed loop of "cloud warning remote guidance on-site landing". In addition, regular communication testing and functional verification of the interconnected system are conducted to ensure that remote operation instructions can be accurately synchronized to the lock code panel, ensuring the reliability of the interconnected functions.
In summary, the interconnection practice between the lock code panel of the machining center and the remote operation and maintenance system is an important component of the digital operation and maintenance of smart factories. Through standardized architecture construction, implementation of core functions, and establishment of collaborative mechanisms, the transformation of the lock code panel from "local isolated operation" to "remote collaborative control" has been achieved. This not only improves operation efficiency and reduces operation costs, but also strengthens the stability and controllability of machining center operation, providing a solid guarantee for the scale and intelligent production of smart factories.
