Description
Technical Field
The invention relates to the technical field of filter debugging equipment, in particular to a network division parameter compensation method, a system, a storage medium and a network division compensation management platform.
Background
In the field of radio frequency communication, a filter is widely used as a frequency selection device, and in a base station for performing signal transmission and reception in a communication system, the filter is used for selecting a communication signal and filtering out clutter or interference signals outside the frequency of the communication signal. For a filter adopting a cavity structure, one cavity can be equivalent to an inductor parallel capacitor to form a resonant level, so that the filtering function is achieved.
A cavity of a common filter with a cavity structure is internally provided with a resonant column, a tuning screw rod and a locking nut for locking the tuning screw rod. At present, all the locking nuts used for locking the tuning screw are locked by adopting standard hexagon nuts, and a standard socket wrench can be adopted for debugging or locking in order to facilitate debugging and locking.
The Dielectric filter (Dielectric filter) is designed and manufactured by utilizing the characteristics of low loss, high Dielectric constant, small frequency temperature coefficient and thermal expansion coefficient, high power bearing and the like of a Dielectric ceramic material, and is composed of a plurality of longitudinal multistage series or parallel ladder circuits of long resonators.
The invention patent with publication number CN1160826C discloses a dielectric filter, as shown in fig. 1, which comprises: in a dielectric block 1 of a substantially rectangular parallelepiped shape, inner conductor holes 2a and 2b (inner surfaces of which are coated with inner conductors 3a and 3b, respectively) are provided, and input/ output electrodes 5a and 5b and an outer conductor 4 are formed on the outer surface of the dielectric block 1. As shown in fig. 2, the inner conductor holes 2a and 2b pass through the first end face of the dielectric block 1 to the second end face facing thereto. The first end face of the dielectric block 1 is an open surface, and the outer conductor 4 is formed on the second end face as a short-circuit surface. The inner conductor holes 2a and 2b have a stepped structure in which the inner diameter on the side of the opening surface is larger and the inner diameter on the side of the short-circuit surface is smaller. The inner conductor holes 2a and 2b are coated with inner conductors 3a and 3b, each of which has one end connected to an outer conductor 4 on the short-circuit surface.
When debugging the filter, the cable is usually used to connect the network analyzer, the calibration piece is used to calibrate the data of the network analyzer, and then the filter is connected with the network analyzer to adjust the filter, so that the parameters of the filter meet the preset requirements.
The network analyzer is a comprehensive microwave measuring instrument capable of scanning and measuring in a wide frequency band to determine network parameters, and is called a microwave network analyzer for short. The method is used for measuring network parameters, and can measure complex scattering parameters of active or passive, reversible or irreversible double-port and single-port networks, such as parameters of a filter, and give amplitude and phase frequency characteristics of each scattering parameter in a frequency scanning manner. The automatic network analyzer can correct errors of the measurement results point by point and convert dozens of other network parameters, such as input reflection coefficients, output reflection coefficients, voltage standing wave ratios, impedance (or admittance), attenuation (or gain), phase shift, group delay and other transmission parameters, isolation, orientation and the like.
Due to a series of possible problems such as design problems, hardware processing errors or assembly errors of the network analyzer, parameter indexes of part of the network analyzer cannot meet preset requirements, for example, insertion loss values, return loss values or inhibition values of one or more Marker points when the filter is measured and the like have certain errors with a standard machine (namely, the network analyzer meeting the preset requirements).
It can be seen that the prior art is still in need of improvement and development.

Detailed Description
The invention provides a network allocation parameter compensation method, a system, a storage medium and a network allocation compensation management platform, and in order to make the purpose, technical scheme and effect of the invention clearer and clearer, the invention is further described in detail below by referring to the attached drawings and taking examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a network division parameter compensation method, and it should be noted that, although the detailed content of the invention is described by using a filter as a debugging product, the network analyzer compensated by the scheme of the invention cannot be limited to be used for debugging the filter, and other devices such as a power divider, a duplexer and a combiner can also be debugged. As shown in fig. 3, the network division parameter compensation method provided by the present invention includes the steps of:
s100, receiving or acquiring an insertion loss value error, a return loss value error and/or a suppression value error.
Insertion loss, i.e., insertion loss, refers to the loss of a signal, typically attenuation, between a transmitter and a receiver, caused by the insertion of a cable or component, and is expressed in terms of the corresponding decibel (db) of the received signal level. The insertion loss value is a value of a Marker point set in advance on an insertion loss curve. The most important point of the insertion loss measurement is consistency, and a supplier and a client both adopt the same measurement means (the return loss value and the inhibition value are the same), that is, the network analyzers used in the measurement need to meet the same performance index requirements.
And S300, displaying the display insertion loss value after adding/subtracting the insertion loss value error to the measurement insertion loss value, the display return loss value after adding/subtracting the return loss value error to the measurement return loss value, and/or the display inhibition value after adding/subtracting the inhibition value error to the measurement inhibition value.
Preferably, the step of receiving or acquiring the insertion loss value error, the return loss value error and/or the suppression value error specifically includes:
s110, acquiring a first actual measurement insertion loss value from a standard machine as a standard insertion loss value, a first actual measurement return loss value as a standard return loss value and/or a first actual measurement inhibition value as a standard inhibition value;
s120, acquiring a second actual measurement insertion loss value of the machine to be compensated as an insertion loss value to be compensated, a second actual measurement return loss value as a return loss value to be compensated and/or a second actual measurement inhibition value as an inhibition value to be compensated;
s130, calculating a difference value between the standard insertion loss value and the insertion loss value to be compensated as an insertion loss value error, a difference value between the standard return loss value and the return loss value to be compensated as a return loss value error, and/or a difference value between the standard inhibition value and the inhibition value to be compensated as an inhibition value error.
Only regarding the acquisition of the insertion loss value error, the return loss value error and/or the suppression value error, the present invention provides a plurality of embodiments (there are many available schemes, and the present invention cannot be listed one by one, and those skilled in the art can select and adaptively adjust according to the embodiments disclosed in the present invention), which specifically include:
example one
The step of acquiring the first measured insertion loss value as the standard insertion loss value, the first measured return loss value as the standard return loss value and/or the first measured inhibition value as the standard inhibition value from the standard machine specifically comprises the following steps: the to-be-compensated machine acquires a first actual measurement insertion loss value from the standard machine as a standard insertion loss value, the first actual measurement return loss value as a standard return loss value and/or a first actual measurement inhibition value as a standard inhibition value.
The standard machine is a network analyzer with parameter indexes meeting detection requirements or the pass rate of a debugged filter exceeding a certain value. The machine to be compensated is a network analyzer with parameter indexes not meeting the requirements but being optimized by software compensation values, and at least one parameter of the machine to be compensated after compensation is the same as or similar to that of a standard machine (the error is considered to be similar within an allowable range).
In specific implementation, the to-be-compensated machine may be connected to the standard machine by a data line, and a data reading program installed on the standard machine or the to-be-compensated machine may be run (if a program that automatically enters a data reading mode after the standard machine and the to-be-compensated machine are connected to each other is pre-built in the standard machine and the to-be-compensated machine, it is not necessary to run a data reading program separately), so that the to-be-compensated machine may read current display data from the standard machine.
Further, when the standard machine reads data from the machine to be compensated, the standard machine is in a measurement state, for example, the standard machine is measuring a certain filter, that is, the compensation mode of the machine to be compensated is preferably customized compensation.
In specific operation, a certain debugged filter is firstly connected to a standard machine (the calibration process of the standard machine is not described here, and the standard machine is calibrated by default after being connected to a cable, for example, a cavity filter, cables connected from an input port and an output port of the standard machine are respectively connected to two measurement interfaces of a certain channel of the filter), the standard machine displays standard parameters of the certain channel of the debugged filter (for the cavity filter, an insertion loss curve, a plurality of insertion loss values, a return loss curve, a plurality of return loss values, an inhibition curve and a plurality of inhibition values are generally displayed at the same time), and then a machine to be compensated is connected to the standard machine through a data line so as to read required parameter values. Certainly, the machine to be compensated is connected to the standard machine first, and the machine to be compensated and the product do not need to be connected to the standard machine through the same interface, so that the connection sequence has no influence on reading of the numerical values.
The step of calculating the difference between the standard insertion loss value and the insertion loss value to be compensated as an insertion loss value error, the difference between the standard return loss value and the return loss value to be compensated as a return loss value error, and/or the difference between the standard inhibition value and the inhibition value to be compensated as an inhibition value error specifically comprises the following steps: and the to-be-compensated machine calculates the difference between the standard insertion loss value and the to-be-compensated insertion loss value as an insertion loss value error, the difference between the standard return loss value and the to-be-compensated return loss value as a return loss value error, and/or the difference between the standard inhibition value and the to-be-compensated inhibition value as an inhibition value error.
After the self-parameters are read by the compensating machine, the parameter errors can be obtained by subtracting the standard parameters from the self-parameters (or subtracting the self-parameters from the standard parameters).
In the case of customized compensation, before reading the parameters of the machine to be compensated, the product needs to be accessed first (if the standard machine is accessed with a certain cavity filter, the machine to be compensated is preferably accessed with the same cavity filter to ensure the calculation accuracy of the parameter errors), and then the data is read, and the errors are calculated (the calibration of the machine to be compensated is not counted here).
In addition, it can be understood that the machine to be compensated does not need to be stored in the machine to be compensated after the parameter error is calculated, and the calculated parameter error can be uploaded to a computer or a server and other devices, and when the machine to be compensated is required to be used, the data is called from the devices in a local area network, a network and other modes.
Further, a product debugging parameter program is stored in the device to be compensated, such as the computer, the computer or the server, after the parameter error is calculated, the product debugging parameter program automatically acquires the calculated parameter error (manual filling, receiving the user operation instruction acquisition and the like are also available), and after the parameter error is filled or replaced, the product debugging parameter program becomes a customized debugging configuration file of the product, (preferably, the customized debugging configuration file can automatically or according to the user operation modification name), and the customized debugging configuration file can be called by the network analyzer; when the product is debugged, the network analyzer can debug the product normally by calling the customized debugging configuration file.
That is, after S100, S300 further includes the steps of: and S200, generating a customized debugging configuration file according to the insertion loss value error, the return loss value error and/or the suppression value error.
