Embodiment 1

[0047] Such as figure 1 As shown, this embodiment provides a device controller reconfigurable system based on the EtherCAT protocol, including an EtherCAT master station, an EtherCAT slave station, a controller kernel reconfiguration and a controller server;

[0048] The EtherCAT master station stably controls the EtherCAT slave station when the system is working. The reconstruction monitoring sub-module, master station reconstruction sub-module, and reconstruction management sub-module are embedded in the EtherCAT master station, but their functions are independent of the EtherCAT master station. They are responsible for monitoring the system. Reconfigurable requirements, start and manage the reconfiguration process of the master station. The refactoring management sub-module is used to manage the refactoring of each part, respectively start the master station refactoring, kernel refactoring, and server refactoring in sequence. The reconfiguration monitoring sub-module is us...

Embodiment approach

[0050] Such as figure 2 As shown, this embodiment provides a reconfigurable implementation method of a device controller based on the EtherCAT protocol, including the following steps:

[0051] S1: The EtherCAT master station periodically sends control messages to control the EtherCAT slave station, the EtherCAT slave station returns the message to the EtherCAT master station, and the reconstruction monitoring sub-module of the EtherCAT master station performs periodic reconstruction monitoring tasks;

[0052] In this embodiment, the real-time monitoring process of the master station reconfiguration monitoring submodule of step S1 works when the equipment is in normal operation, and the EtherCAT master station periodically sends messages to control the work of the slave station. In addition to controlling the operation of each slave station by the read and write) message, a BRW (broadcast read) sub-message is also inserted. This message can monitor the change of the hardware s...

Embodiment 3

[0069] This embodiment provides a storage medium, the storage medium may be a storage medium such as ROM, RAM, magnetic disk, optical disk, etc., and the storage medium stores one or more programs. When the programs are executed by the processor, the above-mentioned embodiment 2 is realized. A reconfigurable implementation method of a device controller based on the EtherCAT protocol.

Abstract

The invention discloses an equipment controller reconfigurable system based on an EtherCAT protocol and an implementation method, and the method comprises the following steps that an EtherCAT master station monitors the change of a hardware topology structure while working periodically, and a controller monitors the change of the hardware topology when a slave station of the controller breaks downor equipment is manually added or stripped, and starts the reconstruction of the whole equipment controller. The reconstruction of the equipment controller comprises hardware reconstruction, master station reconstruction, control kernel reconstruction and server reconstruction. The master station reconstruction process is parallel to the original work period, the configuration work of a new slavestation structure can be completed under the condition of no shutdown, and then the controller sequentially performs kernel and server reconstruction processes. According to the invention, the controller is allowed to carry out online rapid reconstruction without influencing the work of the original normal slave station equipment, the defect of the reconfigurable capability of the existing reconfigurable manufacturing system (RMS) on the hardware level is overcome, the dynamic reconstruction performance of the RMS is improved, the fault response time of the RMS is reduced, and the flexible manufacturing capability of the RMS is enhanced.

Description

technical field [0001] The invention relates to the technical field of EtherCAT device controller reconfiguration, in particular to a reconfigurable system and implementation method of a device controller based on the EtherCAT protocol. Background technique [0002] Reconfigurable manufacturing system (RMS) is an important part of intelligent manufacturing. RMS can quickly respond to changes in production tasks, and adapt to new production tasks and cycles by quickly reorganizing and replacing the manufacturing system structure and its subunits. At present, RMS focuses on the reorganization of the system structure and process levels. Existing RMS involves a wide variety of manufacturing unit equipment, such as machine tools, robots, sensors, etc., usually from different manufacturers, and developers are often only allowed to Based on the existing functions of the provided device controller firmware, limited function expansion (such as integration of custom algorithms) and im...
