The embodiments of the application provide a method for measuring equivalent omnidirectional radiation power of equipment, aiming at the problems that in the related art, the measurement result of EIRP of wireless equipment has certain error, is not consistent with the actual measurement result, and has inaccurate measurement result and poor reliability.
The method for measuring the equivalent omnidirectional radiation power of the equipment according to the embodiment of the application determines the target position of the equipment to be tested when the signal power received by the testing equipment is the maximum value by adjusting the position of the equipment to be tested, then replaces the equipment to be tested with the omnidirectional antenna, enables the omnidirectional antenna to be positioned at the target position, and drives the output power value of the signal transmitter of the omnidirectional antenna when the signal power received by the testing equipment reaches the maximum value, thereby determining the actual equivalent omnidirectional radiation power of the equipment to be tested according to the output power value of the signal transmitter and the gain value of the omnidirectional antenna. Therefore, the equivalent omnidirectional radiation power of the equipment to be measured is measured, the measurement result has no error and conforms to the actual measurement result, and the accuracy and the reliability of the measurement result are improved.
The following describes in detail an apparatus equivalent omni-directional radiation power measurement method, apparatus, device, and medium according to embodiments of the present application with reference to the accompanying drawings.
First, a detailed description is given to the device equivalent omni-directional radiation power measurement method proposed in the embodiment of the present application with reference to fig. 1.
Fig. 1 is a flowchart illustrating an equivalent omni-directional radiation power measurement method of a device according to an embodiment of the present application.
As shown in fig. 1, the device equivalent omni-directional radiation power measurement method of the present application includes the following steps:
Specifically, the method for measuring the equivalent omnidirectional radiation power of the device provided by the embodiment of the present application may be executed by the electronic device provided by the embodiment of the present application, and the electronic device may be configured with a device equivalent omnidirectional radiation power measuring apparatus, so as to accurately measure the equivalent omnidirectional radiation power of the device to be measured. The types of electronic devices are many and can be selected according to application requirements, such as mobile phones, computers, and the like.
The Device Under Test (DUT) may be any Device with a radio frequency function, such as a wireless router, a smart phone, and a tablet computer.
In specific implementation, according to the measurement scenario shown in fig. 2, data transmission between a device Under Test (wireless DUT in fig. 2) and an accompanying device (System Under Test, abbreviated as SUT) may be set, and a receiving antenna of the testing device (spectrometer in fig. 2) receives a transmission signal, so that a target position of the device Under Test when a signal power received by the testing device is a maximum value may be determined by adjusting a position of the device Under Test.
The accompanying equipment can be a smart phone, a tablet computer or a notebook computer. The test device may be a spectrometer or any other instrument capable of studying the spectral structure of an electrical signal, and is not limited herein. In the drawing of this embodiment, the device to be tested is taken as a wireless router, the accompanying device is taken as a notebook computer, and the testing device is taken as a spectrometer.
In an exemplary embodiment, the position of the device to be tested and the orientation of the antenna in the device to be tested at each position may be adjusted to determine the signal power values received by the testing device at each position of the device to be tested and when the antenna is oriented in different directions, and further determine the position of the device to be tested as the target position of the device to be tested when the signal power received by the testing device is the maximum value.
For example, assume that the location of the device under test includes A, B, C three locations, and the antenna in the device under test includes 1, 2, and 3 orientations. Then by locating the dut at position A, B, C and adjusting the orientation of the antenna in the dut at each position, the values of the signal power received by the dut when the dut is located at position a and the antenna is oriented 1, 2, and 3, respectively, when the dut is located at position B and the antenna is oriented 1, 2, and 3, respectively, and when the dut is located at position C and the antenna is oriented 1, 2, and 3, respectively, can be determined. If the signal power value received by the test equipment is the maximum when the equipment to be tested is at the position A and the antenna faces 2, the target position where the equipment to be tested is located can be determined to be the position A.
It should be noted that, in this embodiment of the present application, when the position of the device to be tested is adjusted to determine that the signal power received by the test device is the maximum value and the target position of the device to be tested is located, it is further required that the data transmission speed between the device to be tested and the accessory device meets the following conditions: and the data transmission speed between the equipment to be tested and the accompanying equipment is the data transmission speed of the equipment to be tested under the maximum transmitting power.
Correspondingly, before step 101, the method may further include:
acquiring the maximum transmitting power and a corresponding target rate mode of the equipment to be tested;
and controlling the accompanying equipment and the equipment to be tested to perform data transmission in a target rate mode.
The target rate mode includes parameters such as data transmission speed of the device to be tested.
Specifically, the radio frequency circuit of the device to be tested can be directly installed in the radio frequency test seat, the maximum transmitting power of the device to be tested is obtained by testing the transmitting power of the radio frequency test seat, and the data transmission speed of the device to be tested when the transmitting power of the device to be tested is maximum is recorded, so that the accompanying device and the device to be tested in the measurement scene shown in fig. 2 can be controlled, and data transmission is performed at the data transmission speed corresponding to the device to be tested when the transmitting power is maximum.
Specifically, when the power of the signal received by the test device is determined to be the maximum value, after the target position of the device to be tested is located, the device to be tested may be replaced with an omnidirectional antenna, that is, as shown in fig. 3, the wireless DUT shown in fig. 2 is replaced with an omnidirectional antenna, the omnidirectional antenna is located at the target position of the device to be tested determined in step 101, and meanwhile, the omnidirectional antenna is connected to an external signal transmitter, and a signal transmitted by the signal transmitter is received by a receiving antenna of the test device after passing through the omnidirectional antenna. Then, the output power of the signal emitter is adjusted to change the power of the signal received by the testing equipment, so that the output power value of the signal emitter is detected when the power of the signal received by the testing equipment reaches the maximum value.
The maximum value reached by the signal power received by the test equipment refers to the maximum value of the signal power received by the corresponding test equipment when the equipment to be tested is at the target position in step 101.
And 103, determining the actual equivalent omnidirectional radiation power of the equipment to be tested according to the output power value of the signal transmitter and the gain value of the omnidirectional antenna.
The gain value of the omnidirectional antenna can be determined according to the size, shape and other characteristics of the omnidirectional antenna.
In an exemplary embodiment, after determining the output power value of the signal transmitter, the actual equivalent omnidirectional radiation power of the device under test can be determined by the following formula (1):
EIRP＝P+G (1)
the EIRP is the actual equivalent omnidirectional radiation power of the equipment to be tested, P is the output power value of the signal transmitter, and G is the gain value of the omnidirectional antenna.
It is understood that, through the measurement scenario shown in fig. 3, when the output power value of the signal transmitter is determined, the signal transmitter and the omnidirectional antenna may be connected through a radio frequency coaxial cable. The loss value of the radio frequency coaxial cable may exist, and when the loss value of the radio frequency coaxial cable is small, the loss value of the radio frequency coaxial cable may be ignored, and the actual equivalent omnidirectional radiation power of the device to be tested is determined only according to the output power value of the signal transmitter and the gain value of the omnidirectional antenna, as described in the foregoing embodiment. When the loss value of the radio frequency coaxial cable is large, in order to make the obtained result of the actual equivalent omnidirectional radiation power of the device to be tested more accurate, the loss value of the radio frequency coaxial cable needs to be considered when determining the actual equivalent omnidirectional radiation power of the device to be tested.
That is, before step 103, the method may further include:
obtaining a loss value of the radio frequency coaxial cable;
correspondingly, step 103 may be specifically implemented by:
and determining the actual equivalent omnidirectional radiation power of the equipment to be tested according to the output power value of the signal transmitter, the gain value of the omnidirectional antenna and the loss value of the radio frequency coaxial cable.
In an exemplary embodiment, the actual equivalent omni-directional radiation power of the device under test may be determined by the following equation (2):
EIRP＝P+G-loss (2)
the EIRP is the actual equivalent omnidirectional radiation power of the equipment to be tested, P is the output power value of the signal transmitter, G is the gain value of the omnidirectional antenna, and loss is the loss value of the radio frequency coaxial cable.
It should be noted that, in practical applications, since the electromagnetic environment is complex, there is a lot of unstable interference of radio electromagnetic waves, and thus the whole measurement efficiency and the measurement result may be affected. Therefore, in order to avoid the interference of wireless electromagnetic waves, in this embodiment, when performing the equivalent omnidirectional radiation power measurement of the device, as shown in fig. 2, the device to be measured, the test accompanying device, and the receiving antenna of the test device may be placed in a shielded environment, and as shown in fig. 3, the omnidirectional antenna and the receiving antenna of the test device may be placed in a shielded environment, so as to ensure the stability and reliability of the measurement result.
Further, after the actual equivalent omnidirectional radiation power of the device to be tested is determined, the actual equivalent omnidirectional radiation power of the device to be tested can be compared with a limit value specified by the equivalent omnidirectional radiation power defined by the regulation, so as to judge whether the actual equivalent omnidirectional radiation power of the device to be tested exceeds the regulation limit. For example, after determining the actual equivalent omnidirectional radiation power of the device under test, it may be determined whether the actual equivalent omnidirectional radiation power of the device under test exceeds a limit specified by the European Compliance of Europe (CE) or the Federal Communications Commission (FCC). If the actual equivalent omnidirectional radiation power of the device to be tested is greater than the equivalent omnidirectional radiation power defined by the regulations, the form of the antenna in the device to be tested or the impedance in the radio frequency circuit needs to be adjusted until the actual equivalent omnidirectional radiation power of the device to be tested is less than the equivalent omnidirectional radiation power defined by the regulations.
It can be understood that, the method for measuring the equivalent omnidirectional radiation power of the device provided by the embodiment of the application determines that the device to be measured is under the actual working condition, after the maximum value of the signal power received by the test equipment, the transmitting power of the equipment to be tested under the actual working condition is simulated by adopting a mode of an omnidirectional antenna and a signal transmitter, the signal transmitted by the signal transmitter is received by the receiving antenna of the test equipment after passing through the omnidirectional antenna, further, by adjusting the output power of the signal transmitter, the signal power received by the test equipment in the mode of the omnidirectional antenna plus the signal transmitter, the maximum value of the signal power received by the testing equipment is the same as that of the signal power received by the testing equipment under the actual working condition of the equipment to be tested, and then according to the output power value of the signal transmitter and the gain value of the omnidirectional antenna, the EIRP value of the equipment to be tested under actual work can be obtained, and whether the EIRP value of the equipment to be tested exceeds the regulation limit or not can be further judged.
In the mode for measuring the EIRP, the transmitting power of the equipment to be measured under the actual working condition is simulated by adopting the mode of the omnidirectional antenna and the signal transmitter, so that the measured EIRP is the EIRP value of the equipment to be measured under the actual working condition, and the result of the EIRP value measured by the mode has no error and is consistent with the actual measurement result, thereby being more accurate and more reliable.
The method for measuring the equivalent omnidirectional radiation power of the equipment comprises the steps of firstly adjusting the position of the equipment to be measured to determine the target position of the equipment to be measured when the signal power received by the test equipment is the maximum value, then replacing the equipment to be measured with the omnidirectional antenna, enabling the omnidirectional antenna to be located at the target position, then driving the output power value of a signal transmitter of the omnidirectional antenna when the signal power received by the test equipment reaches the maximum value, and finally determining the actual equivalent omnidirectional radiation power of the equipment to be measured according to the output power value of the signal transmitter and the gain value of the omnidirectional antenna. Therefore, the equivalent omnidirectional radiation power of the equipment to be measured is measured, the measurement result has no error and conforms to the actual measurement result, and the accuracy and the reliability of the measurement result are improved.
Through the analysis, the method for measuring the equivalent omnidirectional radiation power of the equipment, provided by the embodiment of the application, can simulate the transmission power of the equipment to be measured under the actual working condition in a mode of the omnidirectional antenna and the signal transmitter, so as to accurately measure the equivalent omnidirectional radiation power of the equipment to be measured. Further, the method for measuring the equivalent omnidirectional radiation power of the device provided in the embodiment of the present application may further determine whether the impedance of the radio frequency circuit of the device to be measured matches the impedance of the antenna, and the method for measuring the equivalent omnidirectional radiation power of the device provided in the embodiment of the present application is further described below with reference to fig. 4.
Fig. 4 is a flowchart illustrating an equivalent omni-directional radiation power measurement method of a device according to another embodiment of the present application.
As shown in fig. 4, the method for measuring equivalent omni-directional radiation power of the device may include the following steps:
And step 202, controlling the accompanying equipment and the equipment to be tested to perform data transmission in a target rate mode.
And 204, detecting an output power value of a signal transmitter when the power of the signal received by the testing equipment reaches a maximum value, wherein the signal transmitter is used for driving the omnidirectional antenna located at the target position.
And step 206, determining the actual equivalent omnidirectional radiation power of the equipment to be tested according to the output power value of the signal transmitter, the gain value of the omnidirectional antenna and the loss value of the radio frequency coaxial cable.
The detailed implementation process and principle of the steps 201-206 can refer to the detailed description of the above embodiments, and are not described herein again.
Specifically, the radio frequency circuit of the device to be tested can be directly installed in the radio frequency test seat, and the maximum transmission power of the device to be tested can be obtained by testing the transmission power of the radio frequency test seat. In addition, the nominal value of the antenna gain of the antenna specification in the device under test may be used as the gain value of the antenna in the device under test.
In an exemplary embodiment, the reference equivalent omnidirectional radiation power of the device under test may be determined by the following equation (3):
EIRP’＝P’+G’ (3)
the EIRP ' is a reference equivalent omnidirectional radiation power of the equipment to be tested, P ' is the maximum emission power of the equipment to be tested, and G ' is a gain value of an antenna in the equipment to be tested.
It can be understood that, in practical applications, a feeder loss usually exists between a transmitter of the device to be tested and an antenna feed source, and when the feeder loss value is small, the feeder loss value can be ignored as in formula (3), and the reference equivalent omnidirectional radiation power of the device to be tested is determined only according to the maximum transmission power of the device to be tested and the gain value of the antenna in the device to be tested. When the feeder loss value is large, in order to make the obtained result of the reference equivalent omnidirectional radiation power of the device to be tested more accurate, the feeder loss value also needs to be considered when determining the reference equivalent omnidirectional radiation power of the device to be tested.
That is, before step 207, the method may further include:
obtaining the feeder loss between the output end of the equipment to be tested and the antenna feed source;
accordingly, step 207 may be implemented by:
and determining the reference equivalent omnidirectional radiation power of the equipment to be tested according to the maximum transmission power of the equipment to be tested, the gain value of the antenna in the equipment to be tested and the feeder loss between the output end of the transmitter of the equipment to be tested and the antenna feed source.
In an exemplary embodiment, the reference equivalent omnidirectional radiation power of the device under test may be determined by the following equation (4):
EIRP’＝P’+G’-loss’ (4)
the EIRP 'is the reference equivalent omnidirectional radiation power of the equipment to be tested, P' is the maximum transmission power of the equipment to be tested, G 'is the gain value of an antenna in the equipment to be tested, and loss' is the feeder loss between the output end of a transmitter of the equipment to be tested and an antenna feed source.
Step 209 determines that the impedance of the rf circuit of the device under test matches the impedance of the antenna.
Specifically, a range may be preset, and after the actual equivalent omnidirectional radiation power and the reference equivalent omnidirectional radiation power of the device to be tested are determined, the actual equivalent omnidirectional radiation power may be subtracted from the reference equivalent omnidirectional radiation power. If the difference value between the actual equivalent omnidirectional radiation power and the reference equivalent omnidirectional radiation power is within the preset range, the impedance of the radio frequency circuit of the device to be tested can be determined to be matched with the impedance of the antenna.
If the difference value between the actual equivalent omnidirectional radiation power and the reference equivalent omnidirectional radiation power is not within the preset range, the impedance of the radio frequency circuit of the device to be tested can be determined to be not matched with the impedance of the antenna. At this time, the form of the antenna in the device to be tested or the impedance of the radio frequency circuit in the device to be tested may be adjusted, or the form of the antenna in the device to be tested and the impedance in the radio frequency circuit may be adjusted at the same time, and then the actual equivalent omnidirectional radiation power and the reference equivalent omnidirectional radiation power of the device to be tested may be re-determined until the difference between the measured actual equivalent omnidirectional radiation power and the reference equivalent omnidirectional radiation power is within the preset range.
The preset range may be determined arbitrarily according to needs, for example, the preset range may be set to be less than 3 decibels (dB). The form of the antenna may include the shape, size, and the like of the antenna.
In an exemplary embodiment, the impedance in the radio frequency circuit may be adjusted by adjusting a parameter such as a capacitance value or an inductance value in the radio frequency circuit.
It should be noted that, by adjusting the form of the antenna in the device to be tested, or adjusting the impedance of the radio frequency circuit in the device to be tested, or simultaneously adjusting the form of the antenna in the device to be tested and the impedance in the radio frequency circuit until the measured actual equivalent omnidirectional radiation power is within the preset range from the reference equivalent omnidirectional radiation power, the last determined actual equivalent omnidirectional radiation power of the device to be tested can be used as the final effective equivalent omnidirectional radiation power of the device to be tested.
Through the process, the impedance in the radio frequency circuit of the equipment to be tested can be matched with the impedance of the antenna, so that the influence on the wireless performance of the equipment to be tested is avoided when the impedance in the radio frequency circuit of the equipment to be tested is seriously mismatched with the impedance of the antenna, and the wireless performance of the equipment to be tested is improved.
In addition, in the embodiment of the application, the orientation of the antenna in the device to be tested when the device to be tested is configured can also be determined.
Specifically, in the process of measuring the actual equivalent omnidirectional radiation power of the device to be tested, the position of the device to be tested and the orientation of the antenna in the device to be tested at each position may be adjusted, so as to determine the power value of each signal received by the testing device at each position of the device to be tested and when the antenna is oriented in different directions. Therefore, when the impedance of the radio frequency circuit of the equipment to be tested is matched with the impedance of the antenna, in the corresponding measuring process, when the signal power received by the testing equipment is the maximum value, the direction of the antenna in the equipment to be tested is determined as the final direction of the antenna in the equipment to be tested when the equipment to be tested is configured.
That is, the method for measuring equivalent omnidirectional radiation power of a device provided in the embodiment of the present application may further include:
at each position, adjusting the orientation of an antenna in the equipment to be tested to determine the target orientation of the antenna in the equipment to be tested when the signal power received by the test equipment is the maximum value;
correspondingly, after step 209, the method may further include:
and determining the orientation of the target as the orientation of the antenna in the device to be tested.
Specifically, the device to be tested can be placed on the automatic rotating table, so that the orientation of the antenna in the device to be tested is adjusted by controlling the rotation of the rotating table.
During specific implementation, in the actual equivalent omnidirectional radiation power measurement process of the device to be tested, when the target position of the device to be tested is determined, the orientation of the antenna in the device to be tested can be adjusted at each position of the device to be tested, and the target orientation of the antenna in the device to be tested when the signal power received by the testing device is the maximum value is recorded. After the actual equivalent omnidirectional radiation power and the reference equivalent omnidirectional radiation power of the device to be tested are determined, if the impedance of the radio frequency circuit of the device to be tested is determined to be matched with the impedance of the antenna, the recorded target orientation of the antenna in the device to be tested can be determined as the orientation of the antenna in the device to be tested when the device to be tested is configured. If the impedance of the radio frequency circuit of the device to be tested is determined not to be matched with the impedance of the antenna, the form of the antenna in the device to be tested, or the impedance in the radio frequency circuit, or the form of the antenna in the device to be tested and the impedance in the radio frequency circuit are adjusted until the difference value between the measured actual equivalent omnidirectional radiation power and the reference equivalent omnidirectional radiation power is within the preset range, and the target orientation of the antenna in the device to be tested, which is recorded at the last time, can be determined as the orientation of the antenna in the device to be tested when the device to be tested is configured.
Through the process, the orientation of the antenna in the equipment to be tested can be determined when the equipment to be tested is configured.
In order to implement the above embodiments, the present application further provides an apparatus equivalent omni-directional radiation power measurement device.

The types of electronic devices are many and can be selected according to application requirements, such as mobile phones, computers, and the like.
It should be noted that the foregoing explanation of the embodiment of the method for measuring equivalent omnidirectional radiated power of a device is also applicable to the device for measuring equivalent omnidirectional radiated power of a device in this embodiment, and the implementation principle is similar, and is not repeated here.
