Problems solved by technology

However, the great risk of this measure is that once the protective device fails, the PHY chip will be completely in a strong interference environment. At this time, if there is no good method in the software, it may cause the PHY chip to work. Disorder, affecting the normal communication of Ethernet

Abstract

The invention relates to a method for improving stability of a concentrator Ethernet PHY chip. The method comprises the following steps: 1, configuring parameters of an MAC controller of a main control chip of a concentrator; 2, setting a periodic monitoring function, inquiring a value of a connection state register of a PHY chip with frequency f, and judging a connection state of the current linkby adopting a slip judging form; 3, if the connection state of the current link is disconnected, turning to the step 2, and if the connection state of the current link is accessed, checking parametervalues of all the working registers of the PHY chip; and 4, if the connection state of the current link is accessed and a reset tag of the PHY chip is 1, renegotiating an Ethernet working mode, and otherwise turning to the step 2. The method provided by the invention has the advantages that accuracy of judgment is improved, real-time control of the main control chip on working condition of the PHY chip is guaranteed, response speed of the main control chip when the PHY chip is abnormal is improved, communication reliability is guaranteed, and working efficiency of the main control chip is increased.

Description

technical field [0001] The invention belongs to the technical field of electricity consumption information collection systems, and in particular relates to a method for improving the stability of an Ethernet PHY chip of a concentrator in a complex electromagnetic environment. Background technique [0002] With the continuous advancement of power system information transformation, the use of concentrators in centralized copying systems is constantly increasing. Ethernet is widely used in concentrators as an efficient means of communication. Due to the complex and changeable environment of concentrators in actual work, most of them are in the environment of strong magnetic field and high static electricity. As the key core component of Ethernet communication, how the PHY chip works stably in such a complex electromagnetic environment on site directly determines the communication quality of Ethernet communication. [0003] At present, the stability of the PHY chip is generall...
