Step 202, the network equipment updates the first value in the second chip using optimal first object value.
Second chip is based on optimal first object value, adjusts signal amplitude when sending message.
Step 203, out of preset second value range, the network equipment successively traverses each second target value；From preset
In third value range, the network equipment successively traverses each third target value.
Here, the second value range is the value range for adjusting the pre-add weight values of high fdrequency component.Third value range
For the value range of the pre-add weight values for adjusting edge rate.
It is understood why being known as the second value range, third value range, the second target value, third target
Value is the name to carry out convenient for differentiation, is not intended to limit.
Step 204, the network equipment updates the second value in the second chip using the second target value for currently traversing, using working as
The third target value of preceding traversal updates the third value in the second chip.
Here, second value is to be configured in the second chip for adjusting the pre-add weight values of high fdrequency component.Third value is second
What is configured in chip is used to adjust the pre-add weight values of edge rate.It is understood why it is known as second value, third value,
It is only the name carried out convenient for differentiation, is not intended to limit.
After the update for completing this step, the second chip is adjusted when sending message based on the second target value currently traversed
High fdrequency component, and edge rate when sending message is adjusted based on the third target value currently traversed.
Step 205, if not receiving the crc error of the first chip notice within a preset period of time, network equipment stopping time
It goes through.
In the embodiment of the present invention, the network equipment is in optimal pre-add weight values (the optimal first object for determining adjustment signal amplitude
Value) after, successively traverse each pre-add weight values (the second target value) for adjusting high fdrequency component, for adjusting each pre- of edge rate
Weight (third target value).And after traversing and updating each time, monitoring signals transmission quality.That is, monitoring whether to connect again
Receive the crc error of the first chip notice.
If not receiving the crc error of the first chip notice within a preset period of time, illustrate to configure in current second chip
One group of pre-add weight values, can satisfy signal transmission quality requirement, therefore, stop traversal.
If all second target values and third target value have traversed, but still can not eliminate crc error, illustrate currently to believe
Number transmission quality is bad, may not be since variation of ambient temperature causes, warning information can be provided, externally in order to pipe
Reason person is handled in time.
So far, process shown in Fig. 2 is completed.
Can be seen that in the embodiment of the present invention by process shown in Fig. 2, the network equipment by adjustment signal amplitude can not
In the case where eliminating crc error, continues to traverse the corresponding pre-add weight values of high fdrequency component and the corresponding pre-add weight values of edge rate, intend
Improve signal transmission quality by the corresponding pre-add weight values of high fdrequency component and the corresponding pre-add weight values of edge rate.
The process of optimal first object value, which is described, to be determined to the network equipment in step 201 below.Referring to Fig. 3, for this
A kind of implementation process for determining optimal first object value shown in inventive embodiments.
As shown in figure 3, the process can comprise the following steps that
Step 301, if receiving the crc error of the first chip notice within a preset period of time, the network equipment obtains first
The first quantity and the second quantity of chip statistics.
Here, the first quantity is the quantity for the message that the first chip receives within a preset period of time.Second quantity is the
One chip detects the quantity of the message of crc error within a preset period of time.It is understood why being known as the first number
Amount, the second quantity, are only the name carried out convenient for differentiation, are not intended to limit.
The network equipment execute step 102 (using traversal first object value update the second chip in the first value) it
Afterwards, continue monitoring signals transmission quality (crc error whether monitoring receives the notice of the first chip within a preset period of time).
If receiving the crc error of the first chip notice within a preset period of time, illustrate that the second chip is based on current first
After target value adjustment signal amplitude, it is still unable to satisfy signal transmission quality requirement.At this point, the network equipment obtains the from the first chip
One quantity and the second quantity.
Step 302, the second quantity is accounted for the percentage of the first quantity by the network equipment, is determined as crc error accounting.
The crc error accounting can reflect the transmission quality based on current first object value signal adjusted.
Step 303, the corresponding relationship of the network equipment record crc error accounting and current first object value.
Each corresponding crc error of first object value can be obtained by executing step 301~step 303 in the network equipment
Accounting.
Step 304, if receiving the crc error of the first chip notice within a preset period of time, and in the first value range
First object value traversed, from the corresponding relationship of record, search the corresponding first object value of minimum crc error accounting,
As optimal first object value.
That is, when can not still eliminate crc error, selecting available Optimal Signals after having traversed all first object values
First object value when transmission quality (crc error accounting is minimum), as optimal first object value.
So far, process shown in Fig. 3 is completed.
By process shown in Fig. 3, may be implemented to determine optimal first object value.
Optionally, as one embodiment, before executing step 101, the network equipment can also carry out process shown in Fig. 4.
Referring to fig. 4, process is updated for a kind of pre-add weight values shown in the embodiment of the present invention.
As shown in figure 4, the process can comprise the following steps that
Step 401, if receiving the crc error of the first chip notice, the network equipment detects current environmental temperature.
As previously mentioned, will be considered that there may be environment temperatures when the network equipment receives the crc error of the first chip notice
Variation.
In the embodiment of the present invention, the network equipment directly detects environment temperature when perceiving variation of ambient temperature that may be present
Degree.
Step 402, the network equipment determines current environmental temperature said target temperature section.
Ambient temperature range is divided into multiple temperature sections in advance by the embodiment of the present invention.
When determining current environmental temperature by step 401, can be determined by this step belonging to the current environmental temperature
Temperature section.
Here, target temperature section is the affiliated temperature section of current environmental temperature.It is understood why being known as target
Temperature section is only the name carried out convenient for differentiation, is not intended to limit.
Step 403, from the temperature section of local record and the corresponding relationship of one group of pre-add weight values, the network equipment obtains target
The corresponding one group of target pre-add weight values of temperature section.
The embodiment of the present invention can be previously obtained the corresponding one group of pre-add weight values of each temperature section by test.
For example, the network equipment is put into incubator, the network equipment is set to be in different temperature zones by incubator.In each temperature
It spends under section, by the way that different pre-add weight values, the signal of control the second chip output is arranged.Pass through the eye of oscillograph observation signal again
Figure, is compared with preset eye pattern mask, finds out top-quality eye figure.The corresponding one group of pre-add of the top-quality eye figure
The corresponding one group of pre-add weight values of weight values, as Current Temperatures section.Record pair of the temperature section with the one group of pre-add weight values filtered out
It should be related to.
By the above process, the corresponding one group of pre-add weight values of each temperature section can be obtained.Therefore, when the network equipment passes through
After step 402 determines current environmental temperature said target temperature section, it is corresponding that the target temperature section can be inquired by this step
One group of target pre-add weight values.
Here, one group of target pre-add weight values is the corresponding one group of pre-add weight values of target temperature section.It is understood that institute
To be known as one group of target pre-add weight values, it is only the name carried out convenient for differentiation, is not intended to limit.
Step 404, the network equipment updates one group of pre-add weight values in the second chip using one group of target pre-add weight values.
That is, the network equipment utilizes the corresponding one group of pre-add weight values of the affiliated temperature section of current environmental temperature, the second chip is updated
In one group of pre-add weight values.
Second chip sends message to the first chip according to updated pre-add weight values.Thus at a temperature of realizing varying environment
The adaptive configuration of pre-add weight values.
Certainly, since preset pre-add weight values are determined based on temperature section, for example, temperature section central temperature point will be based on
The pre-add weight values measured, the pre-add weight values as Current Temperatures section.So, the pre-add weight values are as other temperature in same temperature section
The pre-add weight values of point are spent, it is not very accurate, it would still be possible to detect crc error.
For this purpose, the embodiment of the present invention continues to execute step 101~step 103.It should be noted that at this point, the first value
Range can be determined according to pre-add weight values corresponding with two adjacent temperature sections of Current Temperatures section.For example, Current Temperatures section
Corresponding pre-add weight values are 64, and preemphasis corresponding with two adjacent temperature sections of the temperature section is respectively 60 and 68.If utilizing
64 update in the second chip after corresponding pre-add weight values, and there are still crc errors, then can traverse preemphasis in 60~68 ranges
Value, to eliminate crc error.
That is, being finely tuned near preset pre-add weight values, to filter out one group of preemphasis under most suitable current environmental temperature
Value.
