Embodiment 1

[0065] figure 1 A schematic diagram of a field bus system provided by an embodiment of the present application is shown, and the details are as follows:

[0066] The field bus system includes a data communication bus and each node connected to the data communication bus. The data communication bus is specifically a bus for realizing multipoint communication. Each node performs mutual data exchange on the data communication bus based on its own node address. communication. Exemplarily, the data communication bus may be a controller area network (Controller Area Network, CAN) bus, an Ethernet (Ethernet) bus, and the like. Specifically, the data communication bus includes at least a control node and at least one access node; the control node is a node that has a fixed node address and can assign addresses to nodes that are dynamically accessed; the access node is a dynamic access data communication bus, and A node that is also connected to a control node through an address assi...

Abstract

The invention is applicable to the technical field of communication, and provides a node address determination method and device, electronic equipment and a storage medium. The node address determination method is applied to a field bus system, and the field bus system comprises a data communication bus, a control node with a fixed node address and a dynamically accessed target access node. The node address determination method comprises the steps that the target access node sends an address allocation request to the control node through an address allocation line; the control node receives an address allocation request; the control node generates corresponding address allocation information according to the address allocation request, and sends the address allocation information to the target access node through the address allocation line; and the target access node receives the address allocation information, and determines the node address of the target access node in the data communication bus according to the address allocation information. According to the embodiment of the invention, the node address can be accurately and efficiently determined for the dynamically accessed node.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a node address determination method, device, electronic equipment and storage medium. Background technique [0002] The fieldbus system is an all-digital, two-way, multi-station communication system that connects intelligent field devices and automation systems. The field bus system includes multiple nodes (one device can be regarded as a node) and communication bus, among which, each node must have its own node address, so that multi-node communication can be accurately and effectively realized in the field bus system. [0003] However, there are sometimes dynamically connected nodes in the fieldbus system, and corresponding node addresses need to be dynamically assigned to these dynamically connected nodes, so that these nodes can realize subsequent communication in the fieldbus system. Some existing ways to determine node addresses for dynamically ...
