In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In practical application, as shown in fig. 1, a terminal device may be connected to an RRU through a BBU (Building Base band unit), a transmission process of data of a 5G radio remote unit is divided into an uplink transmission process and a downlink transmission process, and the data uplink transmission process of the 5G radio remote unit includes: the 5G remote radio unit converts the time domain data received from the electric port into frequency domain data and transmits the frequency domain data to the base station unit through the optical fiber, and the data downlink transmission process of the 5G remote radio unit comprises the following steps: the base station unit transmits the frequency domain data to the remote radio unit through the optical fiber, and the remote radio unit converts the frequency domain data into time domain data and then sends the time domain data to the terminal through the electric port.

In the development stage and the problem location stage of the radio remote unit, a user needs to verify the function of the radio remote unit, for example, an Uplink Channel of the radio remote unit can be detected, as shown in fig. 2, the radio remote unit is connected with a baseband processing unit, the radio remote unit includes an electrical port, a path processing module connected with the electrical port, a Physical Random Access Channel (PRACH) and an Uplink front-end processing module connected with the path processing module, a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH) and a Sounding Reference Signal Channel (Sounding Reference Signal, Signal) connected with the Uplink front-end processing module, frequency domain data compression processing channels respectively connected with the PRACH, PUSCH, PUCCH and SRS, the frequency domain data compression processing channels are connected with the Uplink Channel group processing Channel, the uplink channel group package processing channel is connected with the optical port transmission channel.

When detecting the uplink channel, a user can set an uplink channel source in a channel processing module of the radio remote unit, and the radio remote unit can control the uplink channel source to send a simple test file, such as a constant source, an incremental source and a single sound source, and guide the test file into the uplink channel of the radio remote unit to complete detection of the uplink channel of the radio remote unit.

However, in the above manner, the used test data is pre-stored in the remote radio unit, the test data is relatively simple and inflexible, and cannot be detected in a complex manner, so that the accuracy of detection is insufficient, and the same test data is used for different communication channels, so that the different communication channels cannot be verified accurately in function, and whether the uplink channel of the remote radio unit meets the development requirement cannot be verified reliably and sufficiently.

In the embodiment of the invention, a group of random test Data is driven into a Double Rate synchronous dynamic random access memory (DDR) through external operation and maintenance software, after a piling condition is met, the field programmable gate array continuously writes the test Data in the DDR SDRAM into an uplink communication channel of a radio remote unit, and when outlet Data comparison is needed, only the actually output Data in the field programmable gate array is compared with corresponding Data generated from the outside, so that whether the transmission of each communication channel is correct can be judged.

After receiving the test data, the DDR may send the test data to the array of programmable logic gates in a bus protocol format, and specifically, the DDR may send the test data to the array of programmable logic gates in a Burst (Burst) mode of 512 bits each time.

After the DDR sends the test data, the DDR connector interaction module obtains the test data aiming at the target communication channel in the radio remote unit through the external interface.

Step 302, the field programmable gate array determines the clock frequency corresponding to the target communication channel;

the clock frequency refers to a fundamental frequency of a clock in the synchronous circuit, a measurement unit adopts SI unit hertz (Hz), and the clock frequency corresponding to the target communication channel can be pre-stored in the array of programmable logic gates, such as 491.25 MHz.

After obtaining the test data, the field programmable gate array may first determine a clock frequency corresponding to the target communication channel. Specifically, as shown in fig. 5, after receiving test data sent by the DDR, the DDR piling module may determine a clock frequency corresponding to the target communication channel by acquiring a clock frequency pre-stored in the array of programmable logic gates.

Step 303, the field programmable gate array sends the test data to the target communication channel according to the clock frequency, so as to detect the target communication channel.

After receiving the test data, the target communication channel may generate corresponding test result data based on the test data and transmit the test result data to the terminal.

After receiving the test result data, the terminal can compare the test result data with simulation result data generated in advance based on the test vector, and when the test result data is the same as the simulation result data, the terminal can show that a target communication channel is normal to a user; when the test result data is different from the simulation result data, the terminal can extract the difference data of the test result data and the simulation result data; after the difference data is extracted, the terminal can acquire the problem information corresponding to the difference data from the problem information stored in advance, and then can quickly judge the problems existing in the communication channel.

601, the field programmable logic gate array acquires test data aiming at a target communication channel in the radio remote unit through the external interface;

step 602, the field programmable gate array determines a clock frequency corresponding to the target communication channel;

step 603, the field programmable gate array determines the current data duration;

after determining the clock frequency corresponding to the target communication channel, the field programmable gate array may determine a data duration of the currently received test data.

Specifically, as shown in fig. 4, after receiving test data sent by the DDR, the DDR connector interaction module may determine a duration of currently received data.

Step 604, the field programmable gate array judges whether the current data duration meets a preset piling condition;

after the duration of the current test data is determined, the field programmable gate array can judge whether the duration of the current data meets a preset piling condition or not;

specifically, as shown in fig. 4, after the duration of the current test data is determined, the DDR connector interaction module may determine whether the duration of the current test data meets a preset piling condition.

In an embodiment of the present invention, step 504 may further include the following sub-steps:

a substep S11, determining whether the current data duration is greater than or equal to a preset data duration;

the preset data duration may be 10 ms.

In the judging process, the field programmable gate array can compare the current data duration with the preset data duration so as to judge whether the current data duration is greater than or equal to the preset data duration;

specifically, as shown in fig. 4, after the duration of the current data is determined, the DDR connector interaction module may determine whether the duration of the current test data is greater than or equal to a preset data duration, and for example, the DDR connector interaction module may determine whether the duration of the current test data is greater than or equal to 10 ms.

The write address may be a write address generated from a write RAM state machine.

2. After adding the frame header to the test data, the DDR interface interaction module may send the test data to the frame header switch register.

3. After receiving the test data, the frame header switching register may obtain a corresponding identifier in the test data, where the identifier is used to indicate that the test data is uplink data or downlink data, generate a corresponding enable signal according to the identifier, and send the enable signal and the test data to the data transceiver state machine.

4. After receiving the test data added with the frame header, the AXI data conversion module may convert the format of the test data, for example, convert the test data written with 512bit width into 512 depth into 32bit width 8192 depth data.

5. After converting the format of the test data, the AXI data conversion module may store the converted format test data in the RAM.

6. After generating the write address for storing the test data, the field programmable logic gate array may further generate a read address for reading the test data corresponding to the write address, and send the read address to the AXI control word conversion module.

7. After the AXI control word conversion module receives the read address, the AXI control word conversion module may output a clock corresponding to a target communication channel for data from the RAM according to a RAM read enable signal and a RAM read address signal generated by the RAM state machine.

In the embodiment of the invention, the field programmable gate array acquires test data aiming at a target communication channel in a radio remote unit through an external interface, determines the clock frequency corresponding to the target communication channel, determines the current data duration, judges whether the current data duration meets a preset piling condition or not, sends the test data to the target communication channel according to the clock frequency when the current data duration meets the piling condition so as to detect the target communication channel, and caches the test data when the current data duration does not meet the piling condition, so that the detection of the radio remote unit communication by adopting the field programmable gate array is realized, the operation is simple and efficient, the logical characteristics of the field programmable gate array are fully utilized, and the resource utilization rate is high.
