step S101, the service system of the monitoring server recognizes the condition of the external equipment of the USB interface, and when recognizing the abnormal condition, the service system determines that the interface signal of the USB interface is abnormal.
Specifically, in the embodiment of the present invention, different numbers of USB (Universal Serial Bus ) interfaces are provided on the motherboard of the server, for plugging in external devices and running through the service system of the motherboard of the server. In the embodiment of the invention, the identification condition of the service system to each USB interface external device can be monitored in real time in the operation process of the external device, and when the abnormal condition occurs in the identification, the abnormal condition of the interface signal of the current USB interface is judged. The abnormal conditions of the embodiment of the invention comprise: the external device cannot be identified, or the identification result is discontinuous (i.e. the external device can be identified, and the external device cannot be identified), but the method is not limited to this.
Step S102, on-line adjustment is carried out on preset parameters of the USB interface based on a preset eye pattern tool which is pre-installed in the service system, an eye pattern signal of the preset eye pattern tool is obtained in the adjustment process, and the eye pattern signal is characterized in that the bit results of the serial signals are accumulated, superimposed and displayed in an afterglow mode.
Specifically, in the embodiment of the present invention, the eye diagram tool is designed in advance according to the layout structure of the USB interface in the server, and is installed in the service system in advance. When judging that the interface signal of a certain USB interface is abnormal, carrying out on-line adjustment on the preset parameters of the USB interface based on the eye pattern tool, and acquiring the eye pattern signal of the eye pattern tool in the adjustment process. The preset parameters of the USB interface comprise: the method comprises the steps that the ID number of the USB interface and the configuration parameters of the internal registers of the USB interface represent different USB interfaces, the configuration parameters of the internal registers of the USB interface are adjusted on line, and the configuration parameters comprise: at least one of the high speed transmission bias parameter (Per Port HS TX Bias), the high speed Pre-emphasis bias parameter (Per Port HS Pre-emergencies bias) and the half-bit Pre-emphasis parameter (Per Port Half Bit Pre-emergencies) is by way of example only, and not limitation. The eye pattern tool reads the ID number of the USB interface in the server and the configuration parameters of the internal register of the USB interface, sets corresponding preset parameter adjustment ranges for each configuration parameter in advance, and when a user performs parameter adjustment according to the preset parameter adjustment ranges of each configuration parameter, obtains the parameter value adjusted by the user. The preset parameter adjustment ranges set for each configuration parameter in this embodiment are as follows: per Port HS TX Bias is bits [10:8] (3 bits (0-7 range)), per Port HS Pre-empsis bias is bits [13:11] (3 bits- (0-7 range)), per Port Half Bit Pre-empsis is bits [14] (1 bits (0-1 range)).

In addition, the characteristic of the receiving filter can be adjusted by using the pattern so as to reduce inter-code crosstalk and improve the transmission performance of the USB interface. The embodiment of the invention judges the eye pattern signal quality through the opening degree, the jitter rate and the duty ratio of the eye pattern, because the opening degree of the eye pattern is related to jitter and BER (bit error probability), the larger the opening degree of the eye pattern is, the larger the allowable error of the noise and the jitter is, which indicates that the better the judging sensitivity of the receiver is, and the duty ratio determined by the eye top, the eye fundus and the conversion area is wide indicates that the judging sensitivity of the receiver is reduced. As shown in fig. 2, if the opening degree of the eye pattern reaches a preset opening degree standard threshold, the jitter rate reaches a preset jitter rate standard threshold, and the duty cycle reaches a preset duty cycle standard threshold, the signal quality of the eye pattern signal reaches a preset condition, and the interface signal corresponding to the USB interface is normal; if at least one of the opening degree of the eye pattern does not reach the preset opening degree standard threshold value, the jitter rate does not reach the preset jitter rate standard threshold value or the duty cycle does not reach the preset duty cycle standard threshold value occurs, the signal quality of the eye pattern signal does not reach the preset condition, and the interface signal corresponding to the USB interface is abnormal. The embodiment of the invention determines the preset standard threshold values of the opening degree, the shaking rate and the duty ratio according to the actual experience of engineering personnel, and takes the adjusted preset parameters as the operation parameters of the USB interface.
