Method, system and device for automatically configuring time delay parameters and storage medium

Abstract

The invention provides a method, a system and equipment for automatically configuring time delay parameters and a storage medium, which are used for solving the technical problem that experimental parameters of a network interface cannot be automatically adjusted and configured in the prior art, and the method for automatically configuring the time delay parameters comprises the following steps of: sequentially sending a plurality of different delay durations which can be used by a PHY (Physical Layer) chip to the PHY chip in different time periods, enabling the PHY chip to delay a time sequence signal in the PHY chip by using the corresponding delay duration in the corresponding time period; receiving test data sent by the PHY chip in each time period, and recording the number of error frames generated by communication between the MAC and the PHY chip in the corresponding time period; and setting the delay duration corresponding to the time period generating the minimum number of error frames in all the time periods as the delay duration finally used by the PHY chip.

Description

technical field [0001] The invention relates to the technical field of network interfaces, in particular to a method, system, device and storage medium for automatically configuring delay parameters. Background technique [0002] At present, network devices such as NVR (Network Video Recorder) and Ethernet links of IP Camera (IPC) are generally composed of central processing unit (Central Processing Unit, CPU), Media Access Control layer (Media Access Control, MAC), physical Layer (Physical Layer, PHY) consists of three parts. Since the MAC is a typical digital circuit and the PHY contains a large number of analog devices, the MAC is generally integrated inside the CPU, while the PHY is left outside the CPU. Between MAC and PHY through media independent interface (Media Independent interface, MII), simplified media independent interface (Reduced Media Independent Interface, RMII), gigabit media independent interface (Gigabit Media Independent Interface, GMII), simplified gi...
