Embodiment Construction

[0025] refer to figure 1 , The fast control network structure includes two grouping layers, namely the master station part, and one or more slave station parts.

[0026] The master station includes two standard network communication ports, a real-time data synchronization module, a diagnosis management module, an index number management module, a receiving queue management module and a dual-port redundancy management module, among which, the real-time data synchronization module realizes the real-time data synchronization module. Complete the data transmission between the nodes of each slave station; the main function of the diagnosis management module is to regularly send diagnostic messages to diagnose the operation status and network status of each slave station. If the operation status of the slave station is abnormal, the diagnosis management module will start The configuration function is to reconfigure the slave station; the main function of the index number management ...

Abstract

The invention discloses a design method for rapidly controlling network link access, which is not limited within a specific network medium and physical layer standards. Control nodes are formed by a primary station and a slave station and are connected end to end to form a control network, the main station actively sends a message requesting read-write operation, and the slave station has the main functions of analyzing the message of the main station to carry out the read-write operation on the content of the message, and sending the message back to the main station. The active query mode ofthe primary station avoids carrier wave monitoring conflict in the network, thereby enhancing the real-time property of the network. The primary station timely and periodically sends reading or writing messages to the slave station, which realizes rapid high-precision and high-stability information communicating mechanism.

Description

technical field [0001] The invention belongs to the field of network products, and in particular relates to control network technology for industrial equipment, especially a network control method. This method is a control network transmission design for solving information transmission requirements between controllers and is selected corresponding to different real-time requirements. Different physical layer media have common processing methods. Background technique [0002] The control network is widely used in the field of industrial automation, providing an effective and quick solution for the control information between the controllers of the industrial automation control system. [0003] The conventional network solution has its own shortcomings. During the network transmission process, there are detection conflicts, which will have a great impact on the performance of the network and cannot achieve the real-time performance of the network. In addition, the data volume...
