Specific embodiment
Below with reference to attached drawing, the present invention is described in more detail, it should be noted that lower reference attached drawing is to this
The description that invention carries out is only illustrative, and not restrictive.It can be combined with each other between each difference embodiment, with
Constitute the other embodiments not shown in the following description.
Embodiment 1
Present embodiments provide a kind of power compensating method for radio-frequency module, it is intended to the case where being not connected to test equipment
Under, simplify connection type when radio-frequency module test, thus realize the fast power test and automated power compensation of radio-frequency module,
Suitable for batch testing, batch testing efficiency can be improved, and is had the advantages that easy to operate and at low cost.
According to above-mentioned principle, the power compensating method for radio-frequency module is introduced, as shown in Figure 1, being directed to radio frequency
The power compensating method of module, specifically includes the following steps:
Receive calibration of power instruction；
Control radio-frequency module is instructed to export RF signal according to the frequency offset correction；
The RF signal of radio-frequency module is received, and is converted into actual signal intensity value, is repaired based on the actual signal intensity value
Change register value, to complete power compensation.
Wherein, modification register value refers to the value that power data is stored in modification register.
Signal strength indication, that is, RSSI value as mentioned in the embodiments of the present invention indicates the instruction of received signal intensity, for sentencing
Determine the link quality of radio-frequency module, and determines whether to increase broadcast transmission intensity.
Preferably, calibration of power instruction is received by standard test panel, and controls radio-frequency module output RF signal, wherein on
The standard test panel connection end PC and radio-frequency module is stated, for carrying out sampled data and frequency offset correction, internal installation fpga chip,
And setting signal receives circuit, which includes configurable logic blocks, input/output module and memory.The standard is surveyed
Test plate (panel) connects the end PC by USB interface, and standard test panel receives the calibration of power instruction that the end PC is sent, and passes through UART and radio frequency
Module interacts, that is, realizes the control to radio-frequency module, instructs radio-frequency module according to the calibration of power and exports its RF signal, and
Modify the register value of radio-frequency module.
Preferably, RF signal is exported by way of presetting output interface to radio-frequency module, in the present embodiment, is penetrated
Frequency module presets GPIO mouthfuls as output interface.
Preferably, the RF signal is received using conduction pattern by the signal receiving circuit of standard test panel, and be based on
The RF signal is converted into the actual signal intensity value, passes through the fpga chip of standard testing intralamellar part in the present embodiment
RF signal calculates actual signal intensity value to configurable logic blocks based on the received, uses conduction pattern by RF in the present embodiment
Signal is transferred to standard test panel, and conduction pattern, which refers to, is transferred to standard test panel for RF signal by conductive metal line, can keep away
Exempt from environmental disturbances (Electromagnetic Interference in such as air), to guarantee the accuracy of RF signal.Certainly in other realities of the invention
It applies in example, if coupling plate transmission RF signal can also be used, but according to coupling plate transmission in the environment of no Electromagnetic Interference
The fluctuation for the signal strength indication that RF signal obtains can be higher than conduction pattern, the situation not high suitable for calibration of power required precision.
Preferably, before receiving calibration of power instruction, the radio-frequency module for meeting power standard will be chosen, passes through the radio frequency
Module outputting standard RF signal, and standard RF signal is converted into standard signal intensity value, to obtain standard signal intensity value；
After receiving calibration of power instruction, by actual signal intensity value convert according to practical RF signal and standard signal intensity value into
Row compares, and then modifies register value according to comparison result, to complete power compensation, the calibration of power is realized, to guarantee mould
The consistency of the calibration of power of block.
It is by hardware circuit producer that the present embodiment Plays RF signal, which is converted into RSSI value (i.e. above-mentioned signal strength indication),
Formula go to convert, none reduction formula fixed can directly go the deposit for the ready-made RSSI value of IC for calling producer
Device value goes to control this variable as long as being ensured of same model device, can go to measure a radio-frequency module by relative value
The difference of RSSI value goes to adjust corresponding parameter further according to RSSI value, realizes power compensation.
It is preferably based on actual signal intensity value, actual signal intensity value and above-mentioned standard signal strength indication are compared
It is right, comparison result is obtained, comparison process is completed by the configurable logic blocks of the fpga chip of standard testing intralamellar part.According to than
Pair as a result, standard test panel standard test panel modifies the register value of radio-frequency module by the way of serial ports interaction: when the reality
When border signal strength indication is greater than standard signal intensity value, reduce register value；When the actual signal intensity value is believed less than standard
When number intensity value, increase register value.
Radio-frequency module can directly measure received signal intensity with RF energy dBm, can also use RSSI value；And RSSI
Value is a relative value, it is by space, the influence of the variables such as distance.
In actual operation, the definition of RSSI value oneself is determined by radio-frequency module producer, and a such as producer can define RSSI
=80 corresponding -65dBm；Another can define corresponding -60dBm of RSSI=80 etc..So being to pass through control in practical applications
The intensity of unified one signal of variable dereaction, the difference of these certain signal strengths, I needs the acceptable of a standard
Range float value, if it is regarded as qualification within the scope of the float value, such as: A:RSSI:-62, B:RSSI:-61,
C:RSSI:-55, D:RSSI:-65, E:RSSI:-50 etc..
Therefore RSSI value range is required to be satisfactory -55~-62 in some embodiments of the present invention, so being directed to
Above-mentioned D and E just needs to adjust the register value of corresponding power, and when testing again, the RSSI value of the module will require model
In enclosing, when RSSI value is smaller, illustrates that received signal intensity is weaker, illustrate that radio-frequency module transmission power is less than normal, conversely, explanation connects
The signal strength of receipts is stronger, illustrates that radio-frequency module transmission power is bigger than normal.Such as the RSSI value of above-mentioned E is -50, indicates that power is inclined
Greatly, need to reduce the power of radio-frequency module, and the RSSI value of D is -65, indicates that power is less than normal, needs to increase the function of radio-frequency module
Rate.And increasing or reducing power is exactly to go to realize by the value of the register of modification storage power data.The present invention passes through increase
Power compensation is completed with register value is reduced, this process is to automatically control, and does not need artificially to control, and above-mentioned serial ports interactive mode
Using UART (Universal Serial Bus).
After completing power compensation, then the calibration of power is completed, calibration result is returned to the end PC by logical standard test panel, by PC
The power calibration results of end record radio-frequency module.
