Benefits of technology

This innovation improves upon existing methods for controlling device configurations that only allow certain types of communication networks (such as LANs) or specific parts thereof. It also allows users to monitor various aspects such as how well their equipment works with each other without adding extra components like switches. Overall this makes it more flexible than previous solutions but still provides better performance compared to older options.

Problems solved by technology

Technological Problem addressed in this patents relates to developing a universal monitor solution for all types of electrical devices (vehicles) used within cars without compromising their functionality and usableness. Current methods involve establishing separate networks and proprietors' own software programs, making them difficult to maintain conformance across various models and applications.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Apply the method described in the present invention on a monitoring platform, which is composed of an upper computer (master device) with CAN bus interface and one or more lower controllers with CAN bus ports of the electric vehicle, they They are connected by a CAN bus, and the lower controllers are respectively connected to the nodes of the CAN bus.

[0018] Such as figure 1 Shown, a kind of general-purpose CAN network monitoring method based on network protocol described in the present invention, its specific work flow is as follows:

[0019] 1. Initialize the CAN device, and configure each node with an independent configuration file corresponding to its network protocol. The configuration file includes the information frame ID number, variable name, bit definition, ratio, offset, whether Display, whether to save, trigger and other par

Abstract

The invention provides a general CAN (controller area network) monitoring method based on network protocols. In the method, a configuration file technology is adopted, wherein a configuration file comprises the address, the number, the meaning, the attribute and other information of a lower controller; and an upper computer is used for establishing an interface to monitor the lower controller by calling different configuration files related to the network protocols and displaying or storing information related to equipment. The functions and the information in a software interface of the upper computer are refreshed in accordance with the changes of the configuration files, so that the equipment can be monitored based on the different network protocols by modifying the configuration files only, the monitoring requirements of the equipments with the different network protocols are met and the equipment has better generality.
