Bus topology network ad hoc network method

Abstract

The invention provides a bus topology network ad hoc network method. Thus, a non-host network, automatic time slot allocation and time slot and ID separation can be realized. During the ad hoc networkprocess, a networking structure is automatically established, fault points are automatically diagnosed and positioned, and automatic networking can be completed in the case of fault. The position ofeach device in the network can be quickly positioned, and when a system device or a line fails, the fault can be positioned without manual involvement. The networking configuration process is more intelligent and efficient, the tedious and repetitive workload of an engineer is saved, and the problems of repetitive configuration and confusion caused manually can also be avoided.

Description

technical field [0001] The invention relates to a bus topology network ad hoc network method Background technique [0002] The network constructed based on the bus topology often adopts time-division multiplexing, and the arbitration between modules adopts token, polling, time-division multiplexing and other methods. Generally, a main control module is used for token management, polling, and time slot allocation. In conventional applications, the allocation basis is taken from the device ID or physical MAC. For example, the FlaxRay bus divides time into periodic communication slots and non-periodic communication slots based on the time slot allocation method, and the time slot allocation is performed by the master node. When there are multiple master nodes, it is not applicable, and an additional negotiation process is required. , to ensure that there is only one master node in the system at any time. When the master node fails, it takes time to re-establish the time slot a...

For wired networks, CN201710963166.7’s multi-node automatic networking method based on the CAN bus utilizes the arbitration mechanism of the CAN bus. CAN nodes produce CAN IDs through monitoring, random sending, and competition. During this period, a certain CAN finally determines its own ID. CAN ID may need to go through multiple conflicts and competitions to determine. When the node scale is large, the conflict will be more obvious and the efficiency is low. And this method is only applicable to the network of bus or star structure, not suitable for ring network structure
