Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

An attenuator (attenuator) is an electronic component providing attenuation, and is widely applied to electronic equipment, and its main uses are: (1) adjusting the size of a signal in the circuit; (2) in the comparison method measuring circuit, the attenuation value of the measured network can be directly read; (3) the impedance matching is improved, and if some circuits require a relatively stable load impedance, an attenuator can be inserted between the circuit and the actual load impedance, so that the impedance change can be buffered.

In the test work of wireless communication products, the programmable attenuators can be used in a large amount, and with the continuous and abundant enhancement of test environments, the programmable attenuators with stronger capacity can be added and used together with the existing attenuators.

The programmable attenuators in the market have a plurality of brands, the automation control principle of each brand of attenuator is basically the same, control software is provided, and the control software sends Socket communication commands to remotely control the corresponding attenuators, but because the formats of the control commands of the programmable attenuators of each brand are different, even if the programmable attenuators of the same brand are used, the command formats of the attenuators of different models are different, and the attenuation ranges are also different.

Therefore, when multiple brands and models of attenuators are used in the working environment, control software for controlling multiple brands is needed, and the operation complexity is high.

Specifically, each brand of programmable attenuator generally provides an installation program, when multiple brands and types of attenuators are used, multiple control software needs to be installed, the operation is complex, and along with software and hardware upgrading, an original version program needs to be uninstalled, new version software needs to be reinstalled, and the maintenance cost is high.

Further, when multiple brands and types of programmable attenuators are combined to serve signal power adjustment of multiple CELLs, an operator needs to control multiple pieces of software, and the manual operation complexity is high, fig. 1 is a schematic diagram of controlling the attenuators, as shown in fig. 1, when a tester needs to change the attenuation of antenna power of multiple CELLs (CELLs), multiple types of software need to be controlled to change the power (power) of the relevant CELLs, and the process is complex. For example, when changing the antenna power of CELL1, CELL lx, CELL2, and CELL ly, since CELL1 and CELL lx are controlled by the type 1 attenuator and CELL2 and CELL ly are controlled by the type x attenuator, when controlling the type 1 attenuator and the type x attenuator, switching back and forth between the type 1 control software and the type x control software is required, which is cumbersome and error-prone.

On the other hand, when some characteristics are tested, the existing attenuator control method cannot meet the test requirement well, for example, fig. 2 is a schematic diagram two of controlling the attenuator, as shown in fig. 2, a cell has four antennas, where

antennas

1 and 2 are main antennas, and

antennas

3 and 4 are auxiliary antennas, and each antenna is connected to a certain channel of the programmable attenuator. Wherein, attentuator _ type (1in/2out) is brand name and configuration model of the attenuator, wherein 1in/2out represents that 1 input signal is split into 2 output signals, so that the same CELL signal can be multiplexed to a plurality of Test environments (such as Device Under Test, DUT). The control software of the current programmable attenuator supports direct issuing of a control command, for example, if a tester wants to modify the attenuation values of the antenna 1 and the antenna 2 to be 20dbm, the tester needs to manually write a command: A1P20A2P20, A1 and A2 represent channel numbers, P20 represents attenuation values, and then a down button is clicked to send the attenuation values to the attenuator, which means that in a test step that the power of a main antenna or an auxiliary antenna needs to be adjusted at the same time, a tester must determine the connection relationship between a cell antenna and the attenuator to write corresponding attenuation commands, so that the use complexity is increased. The more times of operation, the more complex the combination relationship and the more difficult it is to use.

In order to solve the above problem, in the embodiment of the present application, the control device may store configuration information of multiple attenuators of different brands and different types in advance, and then after receiving request information of a unified preset format, convert the request information for requesting to attenuate a signal into a control instruction according to different target formats corresponding to different attenuators, and then issue the control instruction to the corresponding attenuator, so as to respond to the request information and control the attenuator to attenuate the signal. Therefore, the control method of the attenuator provided by the application can realize direct control of a plurality of attenuators of different brands and different types based on the request information of the unified preset format, greatly simplifies the flow of control processing, and effectively improves the control efficiency and control precision of the attenuator.

Further, according to the control method of the attenuator, the control device can achieve cloud control over multiple brands and types of attenuators, specifically, the control device can store control command message format specifications supported by different brands and types of attenuators in advance, and meanwhile, can store connection relations between cell signals and the attenuators in advance, so that control over the attenuators can be achieved directly, the flow of control processing is simplified greatly, and control efficiency and control accuracy of the attenuators are improved effectively.

Therefore, by adopting the control method of the attenuator, on one hand, different control software corresponding to different attenuations does not need to be installed in a test environment, and correspondingly, the different control software does not need to be updated and upgraded; on the other hand, in the process of controlling the attenuator, the connection relation of the cell signals needing to be attenuated is not acquired in advance.

That is to say, the control method of the attenuator provided by the application does not need to pay attention to what kind of the attenuator is used when the control of the attenuator is executed, does not need to pay attention to the format specification of the control command message supported by the attenuator and the connection relation between the cell signal and the attenuator, but only needs to pay attention to the test service, and further saves the time cost and the labor cost on the basis of improving the control efficiency and the control precision.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

An embodiment of the present application provides a method for controlling an attenuator, fig. 3 is a schematic implementation flow diagram of the method for controlling an attenuator provided in the embodiment of the present application, as shown in fig. 3, in the embodiment of the present application, the method for controlling an attenuator by a control device may include the following steps:

step 101, analyzing the received request information according to a preset format, and obtaining a signal identifier and an attenuation parameter corresponding to the request information.

In the embodiment of the application, after receiving the request information, the control device may perform parsing processing on the request information according to a preset format, so that a signal identifier and an attenuation parameter corresponding to the request information may be obtained.

It should be noted that, in the embodiment of the present application, the preset format may be a unified message format predefined by the control device. Specifically, the preset format used by the control device to parse the request message is uniform no matter whether the sending end of the request message is the same or not and whether the attenuator used for controlling the request message is the same or not.

It will be appreciated that in embodiments of the present application, the request message is a request for attenuation processing of one or more signals.

Further, in the embodiment of the present application, after the control device analyzes the received request message according to the preset format, a signal identifier and an attenuation parameter carried in the request message may be determined, where the signal identifier may indicate a signal that needs to be attenuated by controlling the attenuator, and the attenuation parameter may be used to quantify the degree of attenuation.

In the embodiment of the present application, the request information may be a request for performing attenuation processing on one signal or a request for performing attenuation processing on a plurality of signals. Accordingly, after the control device analyzes the request information, it may determine the signal identifier and the attenuation parameter corresponding to one signal to be attenuated, or determine a plurality of signal identifiers and a plurality of attenuation parameters corresponding to a plurality of signals to be attenuated.

For example, in the present application, the signal identifier corresponding to the request information may include a cell identifier and an antenna identifier, and the attenuation parameter corresponding to the request information may include an attenuation value.

Further, in the embodiment of the present application, after the control device analyzes the received request message according to the preset format, the test environment name carried in the request message may also be determined.

It can be understood that, in the embodiment of the present application, the control device may receive the request message before parsing the request message, where the control device may receive the obtaining request message through a Graphical User Interface (GUI) or an automation control Interface when receiving the request message.

For example, in the present application, the control device may receive a request message from a World Wide Web (Web) GUI, and may also receive an http service request from automation (automation). Therefore, the control method of the attenuator can be multiplexed in different scenes of manual testing and automatic testing.

It is understood that, in the embodiment of the present application, fig. 4 is a schematic diagram of generating the request information, as shown in fig. 4, each tester may directly access the web address of the fader cloud service and enter the GUI control page without installing the control software of the fader. Information such as a CELL name, a signal number, a connection state, a current attenuation value and the like is contained in a page, and a tester can generate request information by dragging a control node to adjust left and right, so that the power of the CELL is controlled in real time.

It can be understood that, in the embodiment of the present application, fig. 5 is a schematic diagram ii for generating request information, and as shown in fig. 5, after the automation framework completes assembling the request message, an http service request is initiated, and automation does not need to install control software of the attenuator.

It can be seen that in the present application, the control device does not need to rely on the control software of the attenuator in either a manual control process or an automated control process.

For example, in the present application, the control device receives an http service request message (request message) generated by a tester through a GUI, where a data format of the request message satisfies a preset format, and the request message may carry a test environment name, a CELL name (CELL identifier), an antenna number (antenna identifier), and an attenuation value (attenuation parameter). For example, the request message is expressed based on a preset format as:

[ { 'test _ rack _ name': test _ rack _1',' Signal _ index ': Signal _3', 'value': 39',' CELL _ name ': CELL _ name _2' }, … ], wherein test _ rack _ name indicates a test environment name, CELL _ name indicates a CELL name (CELL identification), Signal _ index indicates an antenna number (antenna identification), and value indicates an attenuation value (attenuation parameter).

Correspondingly, after the control device analyzes the request message according to the preset format, the test environment name corresponding to the request message is determined to be test _ rack _1, the CELL name is CELL _ name _2, the antenna number is signal _3, and the attenuation value is 39 db.

It is to be understood that, in the present application, the request message may be a list structure, where each element is a dictionary structure, and the dictionary interface may be configured to determine the CELL identifier, the antenna identifier, and the attenuation parameter, that is, each dictionary may record the attenuation information of a certain antenna of a certain CELL.

And 102, determining an attenuator to be controlled in the plurality of attenuators based on the signal identification.

In the embodiment of the application, after the control device parses the received request information according to a preset format and obtains the signal identifier and the attenuation parameter corresponding to the request information, the control device may further determine, based on the signal identifier, an attenuator to be controlled from the connected attenuators.

It is understood that in the embodiment of the present application, a plurality of attenuators may be connected to the control device, wherein the types and brands of the plurality of attenuators may not be identical. Specifically, one or more attenuators of the plurality of attenuators, that is, the attenuators to be controlled, may perform attenuation processing of the signal in response to the request information received by the control device.

It can be understood that, in the embodiment of the present application, since the control device analyzes the request information to determine that the signal identifier corresponds to one signal that needs to be attenuated, the signal identifier may also be multiple signal identifiers corresponding to multiple signals that need to be attenuated. Therefore, the attenuator to be controlled determined by the control device based on the signal identification may be one attenuator for which a connection has been established, or may be a plurality of attenuators for which a connection has been established.

It should be noted that, in the embodiment of the present application, a configuration relation mapping table may be stored in advance in the control device, where the configuration relation mapping table may determine a connection relation between the attenuator and the cell and the antenna, that is, the attenuator performing attenuation processing on a certain signal may be determined by the configuration relation mapping table.

For example, in the present application, the configuration relation mapping table may store the signals and the identifications of the attenuators having the configuration relation, for example, table 1 is a configuration relation mapping table one, as shown in table 1, for different signals, the attenuators configured to perform the signal attenuation processing may also be different, where, based on the configuration relation between the signals and the attenuators, the signal identifications and the attenuator identifications may be stored correspondingly, and the attenuator, for example, the attenuator identification a, may perform the attenuation processing on the signal of the signal identification 3.

TABLE 1

That is to say, in the embodiment of the present application, when determining an attenuator to be controlled among a plurality of attenuators based on the signal identifier, the control device may first determine an attenuator identifier corresponding to the signal identifier based on a configuration relationship mapping table; the attenuator to be controlled can then be determined further on the basis of the attenuator identification.

It can be understood that, in the embodiment of the present application, since the signal identifier may include a cell identifier and/or an antenna identifier, the configuration relationship mapping table may also store identifiers of cells and/or antennas and attenuators having a configuration relationship, for example, table 2 is a configuration relationship mapping table two, as shown in table 2, for different signals, attenuators configured to perform the signal attenuation processing may also be different, where, based on the configuration relationship between the cell and the antenna and the attenuator corresponding to the signal, the cell identifier and the antenna identifier may be stored in correspondence with the attenuator identifier, and for example, the attenuator of the attenuator identifier a may perform the attenuation processing on the signal of the antenna 2 in the cell identifier b.

TABLE 2

That is to say, in the embodiment of the present application, when determining an attenuator to be controlled in a plurality of attenuators based on the signal identifier, the control device may also determine, based on a configuration relationship mapping table, an attenuator identifier corresponding to the cell identifier and/or the antenna identifier; the attenuator to be controlled can then be determined further on the basis of the attenuator identification.

Further, in an embodiment of the present application, fig. 6 is a schematic view of an implementation flow of a control method of an attenuator provided in the embodiment of the present application, and as shown in fig. 6, after a controller parses received request information according to a preset format and obtains a signal identifier and an attenuation parameter corresponding to the request information, that is, after step 101, the method for controlling a control device to control the attenuator may further include the following steps:

and 105, determining a channel identifier of the attenuator to be controlled, which corresponds to the signal identifier, based on the configuration relation mapping table.

And step 106, determining an input channel and an output channel of the attenuator to be controlled according to the channel identification.

In the embodiment of the application, after the control device analyzes the received request information according to a preset format and obtains the signal identifier and the attenuation parameter corresponding to the request information, the control device may further determine, based on a configuration relationship mapping table, the channel identifier of the attenuator to be controlled, which corresponds to the signal identifier. Then, the control device may determine, by using the channel identifier, an input channel and an output channel of the attenuator to be controlled, which correspond to the signal to be attenuated.

It is understood that in the embodiments of the present application, the channel identification of the attenuator to be controlled may include an identification of an input channel and an identification of an output channel.

Further, in the embodiments of the present application, for the multi-channel attenuator, the attenuator may perform attenuation processing on a certain signal by using a part of the input channels and a part of the output channels, that is, a certain signal may be input from one of the output channels and then output from one of the output channels. Therefore, in order to control the attenuator based on the request information, the control device needs to determine the input channel and the output channel of the attenuator to be controlled corresponding to the signal identifier in the request information.

It should be noted that, in the embodiment of the present application, the control device may determine, through a pre-stored configuration relationship mapping table, not only the attenuator that performs the attenuation processing on a certain signal, but also an input channel and an output channel of the attenuator corresponding to the signal through the configuration relationship mapping table.

For example, in the present application, the configuration relationship mapping table may store the signal and the identifier of the attenuator and the identifier of the channel of the attenuator, which have the configuration relationship, for example, table 3 is a configuration relationship mapping table three, as shown in table 3, for different signals, the identifier of the attenuator or the channel of the attenuator performing the signal attenuation processing may also be different, wherein, based on the configuration relationship between the signal and the attenuator, the signal identifier may be stored in correspondence with the identifier of the attenuator and the identifier of the channel of the attenuator, for example, a path formed by the input channel of the channel identifier 1 and the output channel of the channel identifier 6 of the attenuator identifier a, and the signal of the signal identifier 3 may be subjected to the attenuation processing.

TABLE 1

				1	A	2	3
2	B	2	1
				3	A	1	6
4	E	5	2
				……	……	……	……

Therefore, in the embodiment of the present application, after determining the signal identifier of the signal to be attenuated, which is carried in the request information, the control device may further determine, based on a pre-stored configuration relationship mapping table, the attenuator to be controlled, that is, the attenuator to be controlled, and the channel of the attenuator to be controlled, that is, the input channel and the output channel of the attenuator to be controlled.

Further, in an embodiment of the present application, fig. 7 is a schematic flow chart illustrating an implementation process of a control method of an attenuator provided in the embodiment of the present application, as shown in fig. 7, before the control device determines an attenuator to be controlled among the plurality of attenuators based on the signal identifier, that is, before step 102, the method for the control device to control the attenuator may further include the following steps:

step 107, establishing connection with a plurality of attenuators; wherein the plurality of attenuators includes an attenuator to be controlled.

Step 108, establishing a plurality of service objects corresponding to a plurality of attenuators; wherein one attenuator corresponds to one service object.

In an embodiment of the present application, the control device may first establish a connection with a plurality of attenuators of which brands and types are not completely the same, wherein the attenuator to be controlled corresponding to the request information also belongs to at least one of the plurality of attenuators with which the connection has been established.

Then, the control device may establish a service object for each of the plurality of attenuators, that is, establish a plurality of service objects corresponding to the plurality of attenuators, where one attenuator corresponds to one service object.

It should be noted that, in the embodiment of the present application, a message queue is set in each service object established by the control device, and the message list is used for buffering messages. When the control device uses the message list to cache the message, the control device needs to cache the message according to the message format applicable to the corresponding attenuator.

And 103, generating a control instruction according to the target format and the attenuation parameter corresponding to the attenuator to be controlled.

In the embodiment of the application, after determining the attenuator to be controlled in the plurality of attenuators based on the signal identifier, the control device may further determine a target format corresponding to the attenuator to be controlled, and then generate a control instruction corresponding to the request information according to the target format and the attenuation parameter.

It can be understood that, in the embodiment of the present application, when the control device generates the control instruction, the attenuator identifier and the attenuation parameter may be formatted based on the target format, that is, the control device may format the attenuator identifier of the attenuator to be controlled and the attenuation parameter in the request message according to the target format corresponding to the attenuator to be controlled.

For example, in the embodiment of the present application, if it is determined that the attenuator identifier of the attenuator to be controlled is 2, such as attenuator _2, and the attenuation parameter is 39db, the control instruction generated by the control device based on the target format of the attenuator to be controlled may be:

attenuator_2:P39；…；

the control command may indicate that the path loss bit 39db is set for the attenuator identified as 2.

It can be understood that, in the embodiment of the present application, when the control device generates the control instruction, the attenuator identifier, the channel identifier, and the attenuation parameter may further be formatted based on the target format, that is, the control device may format the attenuator identifier of the attenuator to be controlled, the channel identifier of the attenuator to be controlled, and the attenuation parameter in the request message according to the target format.

For example, in the embodiment of the present application, if it is determined that the attenuator identifier of the attenuator to be controlled is 5, such as attenuator _5, the channel identifier of the input channel is 3, the channel identifier of the output channel is 1, and the attenuation parameter is 39db, the control instruction generated by the control device based on the target format of the attenuator to be controlled may be:

attenuator_5:IN3_OUT1_P39；…；

the control command may indicate that the attenuator is designated 5 and the path loss is set to 39dB for the path with 3 inputs and 1 output.

It is understood that, in the embodiment of the present application, the attenuator to be controlled, which is determined by the control device based on the signal identification, may be one attenuator of the established connection, or may be a plurality of attenuators of the established connection. Therefore, when the control command is generated, one control command may be generated to control one attenuator to be controlled, or a plurality of control commands may be generated to control a plurality of attenuators to be controlled.

Further, in an embodiment of the present application, fig. 8 is a fourth schematic implementation flow chart of the control method of the attenuator provided in the embodiment of the present application, as shown in fig. 8, after the control device generates the control instruction according to the target format corresponding to the attenuator to be controlled and the attenuation parameter, that is, after step 103, the method for the control device to control the attenuator may further include the following steps:

and step 109, storing the control instruction into a message queue in the service object corresponding to the attenuator to be controlled.

In the embodiment of the application, after the control device completes the analysis of the request information based on the preset format and completes the generation of the control instruction based on the target format of the attenuator to be controlled, the control instruction may be stored in the message queue in the service object of the corresponding attenuator to be controlled.

It will be appreciated that in the present application, different control instructions for attenuating different signals may be buffered in a message queue in the service object of a particular attenuator in the control device.

And step 104, sending a control instruction to the attenuator to be controlled.

In the embodiment of the application, after the control device generates the control command according to the target format and the attenuation parameter corresponding to the attenuator to be controlled, the control device may send the control command to the corresponding attenuator to be controlled.

It can be understood that, in the present application, if different control instructions for attenuating different signals are cached in a message queue in a service object of a certain attenuator, the control device may issue the control instructions to the attenuator in sequence, so as to perform attenuation processing on different signals in sequence.

It should be noted that, in the embodiment of the present application, since the control device may generate one control instruction to control one attenuator to be controlled, or may generate a plurality of control instructions to control a plurality of attenuators to be controlled. Therefore, when sending the control instruction to the faders, the control apparatus needs to send each control instruction to a corresponding one of the faders.

Further, in an embodiment of the present application, fig. 9 is a schematic view of an implementation flow of a control method of an attenuator provided in the embodiment of the present application, as shown in fig. 9, after the control device sends the control instruction to the attenuator to be controlled, that is, after step 104, the method for the control device to control the attenuator may further include the following steps:

and step 110, sending a query instruction to the attenuator to be controlled.

And step 111, receiving a control result returned by the attenuator to be controlled.

In the embodiment of the application, after the control device generates the control instruction and sends the control instruction to the attenuator to be controlled, the control device may also send an inquiry instruction to the attenuator to be controlled, and then may receive a control result returned by the attenuator to be controlled. Wherein the control result can represent the working state of the attenuator to be controlled.

It should be noted that, in the embodiment of the present application, the request information received by the control device is used to perform attenuation processing on one or more signals, and after generating one or more control instructions based on the request information and issuing the one or more control instructions to the one or more attenuators, the control device may further query, for the one or more attenuators, an attenuation result of the attenuation processing performed on the one or more signals by the one or more attenuators based on the control instructions, so that whether the corresponding attenuation processing is completed may be determined by the one or more attenuation results returned by the one or more attenuators.

Further, in the embodiment of the present application, after the attenuator obtains the control result of the signal attenuation processing by sending an inquiry instruction to the attenuator to be controlled, the control result may be subjected to feedback processing, for example, the control device may return the control result to a user.

Further, in an embodiment of the present application, the method for controlling the attenuator by the control device may further include the steps of:

and step 112, receiving an updating instruction.

And 113, updating the configuration relation mapping table based on the updating instruction.

In the embodiment of the present application, the control device may further receive an update instruction, and then may perform update processing on the pre-stored configuration relationship mapping table by using the update instruction. Namely, the configuration relation between the attenuator and the signal is updated in response to the updating instruction.

That is to say, in the present application, there is no need to install different types of control software in the test environment, and when executing the control of the attenuator, it is no longer necessary to pay attention to what kind of attenuator is used, and it is no longer necessary to pay attention to the control command message format specification supported by the attenuator, and the connection relationship between the cell signal and the attenuator, but only to the test service, and then on the basis of improving the control efficiency and the control accuracy, the time cost and the labor cost are also saved, 1) the workload of the attenuator control service maintenance is reduced.

The control device can have more abundant customized functions, for example, a cell signal change process configuration file can be established, and a user can automatically modify signals of a plurality of cells according to the content of the configuration file by opening the change process file, so that the working efficiency is further improved.

Based on the foregoing embodiments, in yet another embodiment of the present application, fig. 10 is a first schematic diagram of a control method of an attenuator, and as shown in fig. 10, a specific framework for implementing control of the attenuator may include a three-layer structure, where the first layer structure includes multiple-brand and multiple-model attenuators, the second layer structure includes control equipment, and the third layer structure includes a test line.

Specifically, in the embodiment of the present application, in the multi-brand and multi-model attenuators in the first layer structure, each attenuator is configured with a socket communication interface for establishing a communication connection with the control device in the second layer structure.

It is understood that in the embodiments of the present application, the attenuators (such as the attenuator 1, the attenuator 2, and the attenuator 3) in the first layer structure may be of different brands or different types of attenuators, that is, if a common technology is used, the control of the attenuators needs to be performed depending on the control software 1, the control software 2, and the control software 3 corresponding to the attenuator 1, the attenuator 2, and the attenuator 3, respectively.

Specifically, in the embodiment of the present application, the control device in the second layer structure can run a cloud service that controls attenuators of different types and brands.

It should be noted that, in the embodiment of the present application, the control device may establish corresponding fader service objects for each of the connected faders, for example, establish the service object 1 corresponding to the fader 1, the service object 2 corresponding to the fader 2, and the service object 3 corresponding to the fader 3.

Further, in the embodiment of the present application, a message queue is disposed in the service object corresponding to each attenuator, where the message queue may be used to buffer messages of the corresponding attenuator, such as a control instruction.

Specifically, in the embodiment of the present application, the test line in the third layer structure may be used for issuing a request message, that is, the control device in the second layer structure may receive the request message through the test line in the third layer.

It should be noted that, in the embodiment of the present application, the request message may be manually issued by a tester, for example, the tester issues the request message to the control device through a WEB GUI interface; the request message can also be automatically issued by the automatic test system.

That is, the control device runs cloud services that control attenuators of different types and brands, and can be reused in a manual test environment and an automatic test environment.

It should be noted that, in the embodiment of the present application, the request message received by the control device in the second layer is written according to a uniform data format, for example, a preset format, and accordingly, the control device may analyze the request message based on the preset format to determine the signal that needs to be attenuated. Then, the pre-stored configuration relation mapping table is utilized to further determine the attenuator for executing the attenuation processing of the signal, so that the data obtained by analysis can be formatted according to different target formats corresponding to different attenuators, corresponding control commands are generated, and finally the control commands corresponding to different attenuators can be issued to the message queues of corresponding service objects, so that the control commands are respectively sent to the corresponding attenuators, and the control of the attenuators is realized.

For example, in the present application, if the control device analyzes the request message to determine a signal to be attenuated, and then determines, based on the configuration relationship mapping table, that an attenuator that performs attenuation processing on the signal to be attenuated is an attenuator 2, the control device may format data obtained by analysis according to a target format 2 corresponding to the attenuator 2 to generate a corresponding control command 2, and finally may issue the control command 2 to a message queue of a corresponding service object 2 to send the control command 2 to the corresponding attenuator 2, so as to implement control of the attenuator 2.

Further, in an embodiment of the present application, fig. 11 is a schematic diagram of a control method of an attenuator, as shown in fig. 11, when determining that antenna power of CELL1, CELLx, CELL2, and CELLy needs to be changed, a tester may directly send a request message to a control device, the control device may analyze each request message using a uniform preset format, determine an attenuator to be controlled that performs attenuation processing and corresponds to each request message, then generate a corresponding control instruction according to a target format corresponding to each attenuator to be controlled, and issue the control instruction to the corresponding attenuator to be controlled.

In contrast to fig. 1 described above, when changing the antenna power of CELL1, CELLx, CELL2, CELLy, there is no need to switch back and forth between the control software of type 1 and the control software of type x. That is, when the attenuation of the antenna power of a plurality of CELL is changed, the power (power) of the relevant CELL does not need to be changed by depending on a plurality of types of software, and the control flow is simplified.

Therefore, according to the control method of the attenuator, the control device stores specific parameters, configuration relations and the like of the plurality of attenuators in advance, when the attenuator is controlled, the control device only needs to receive a request message including specific information (such as corresponding cell identification, antenna identification and other related information) of a signal to be attenuated, and can control the corresponding attenuator, so that cloud control can be achieved for the plurality of brands and types of attenuators, control software does not need to be installed in a test environment, the brand and type of the attenuator does not need to be concerned, and control command message format specifications supported by the attenuator and the connection relations between the signal and the attenuator do not need to be concerned.

It can be understood that, in the embodiment of the present application, the attenuator cloud service provided by the control device may be reused for manual testing and automated testing, which may provide a friendly GUI interface for manual testing and also provide a compact control interface for automated testing, so that a tester no longer needs to write a bottom-layer control command for controlling the attenuator.

Further, in the embodiments of the present application, the control device may further customize the control service according to the test requirement, for example, the main antenna set and the auxiliary antenna set may contain multiple signals, and when the test requires to adjust the main antenna set and the auxiliary antenna set to different values, the control scheme based on the antenna set may be customized, and the customization requirement of other automation adjusting schemes may be met.

The control method of the attenuator provided by the present application can also provide customizable functions. Specifically, on the user equipment side, when a user needs to adjust a signal of a certain cell, if the cell is configured with multiple antennas, the user may select antennas and attenuation values that need to be uniformly adjusted, and generate corresponding request information, and after receiving the request information, the control device may control corresponding attenuators based on the request information, so as to implement attenuation of the antennas that need to be uniformly adjusted in the cell according to the attenuation values.

Fig. 12 is a schematic diagram showing implementation of a customized function on a client device side, as shown in fig. 12, in a WEB GUI interface, a cell further includes multiple antennas, when a user needs to adjust a signal of the cell, a tab bar in the WEB GUI interface may be used to tag four antennas that need to be uniformly adjusted, then any one antenna may be adjusted to adjust the same attenuation value of all antennas, and the user does not need to adjust each antenna four times.

Based on fig. 12, fig. 13 is a schematic diagram illustrating implementation of a customized function on the client device side, as shown in fig. 13, after the unified adjustment of the four antennas is completed, when a user needs to adjust one of the two antennas, the tags on the two antennas are removed, and if the tags of the third and fourth antennas are removed, the attenuation of the three antennas can be controlled, without affecting the other antennas.

In the embodiment of the application, after receiving the request information, the control device may perform parsing processing on the request information according to a preset format, so as to obtain a signal to be attenuated corresponding to the request information, and a signal identifier and an attenuation parameter of the signal to be attenuated.

For example, in the present application, the client device may send an http service request message to the control device, where the request message conforms to a uniform data format predefined by the control device, such as a preset format, and the request message includes a name of the test environment, a name of the CELL, an antenna number, and an attenuation value.

The preset format may be:

[{'test_rack_name':'test_rack_1','Signal_index':'signal_3','value':'39','CELL_name':'CELL_na me_2'},…]

the request message may be in a list structure, where each element is in a dictionary structure, each dictionary recording attenuation information for a certain antenna of a certain CELL.

And 203, determining an attenuator to be controlled corresponding to the signal to be attenuated based on the configuration relation mapping table.

Further, in the embodiment of the present application, the control device may further analyze the attenuator number, the input channel, and the output channel of the attenuator to be controlled according to a well-defined configuration relationship mapping table, such as the above tables 1, 2, and 3.

For example, the map may also be a well-defined configuration relationship file, where the configuration relationship file is convenient for a user to plan and adjust a connection relationship between the CELL and the faders, and basic information, ip addresses, etc. of some faders, and the configuration relationship file may be represented as follows:

and step 204, generating a control instruction according to the target format corresponding to the attenuator to be controlled.

In the embodiment of the application, after determining the attenuator to be controlled corresponding to the signal to be attenuated in the plurality of attenuators based on the configuration relationship mapping table, the control device may further determine a target format corresponding to the attenuator to be controlled, and then generate the control instruction corresponding to the request information according to the target format and the attenuation parameter.

For example, in the embodiment of the present application, the control instruction after the formatting process may be represented as:

attenuator_2:IN3_OUT1_P39；…；

wherein the control command represents an attenuator with the control name of attenuator _2, and the path loss of a path with an inlet of 3 and an outlet of 1 is set to 39 dB.

And step 205, sending a control instruction to the attenuator to be controlled.

And step 206, acquiring a control result corresponding to the control instruction.

And step 207, feeding back a control result.

In the embodiment of the application, after obtaining the control result corresponding to the control instruction, the control device may feed back the control result to the client device.

Exemplarily, in an embodiment of the present application, fig. 15 is a schematic diagram of a control method of an attenuator, as shown in fig. 15, a control device capable of providing an attenuator control cloud service may receive an http service request (request message) sent from a tester through a WEB GUI and/or an http service request (request message) sent from an automation, where the request message includes an attenuation request for a certain CELL signal or certain CELL signals, and it should be noted that a format of the request message is well defined by the control device, that is, the control device receives the request message according to a well-agreed and uniform preset format. After the request message is obtained, the control device may convert the unified message format into the dedicated message format for attenuators of different brands, that is, the control device generates the control instruction by using different target formats corresponding to different attenuators, and then sends the control instruction to the attenuator.

Specifically, in the embodiment of the present application, the request message received by the control device is written according to a uniform data format, such as a preset format, and accordingly, the control device may analyze the request message based on the preset format to determine that the CELL signal needs to be attenuated. Then, the pre-stored configuration relation mapping table is utilized to further determine the attenuator for executing the attenuation processing of the CELL signal, further format the data obtained by analysis according to different target formats corresponding to different attenuators to generate corresponding control commands, and finally the control commands corresponding to different attenuators can be issued to the message queues of corresponding service objects so as to respectively send the control commands to the corresponding attenuators to realize the control of the attenuators.
