[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] For example, see Figure 1 As shown, the present invention provides a mobile phone communication test system based on radio frequency technology, including a communication test module, a data analysis module and a communication judgment module;

[0063] The communication test module is used to perform sensitivity test on the reference mobile phone, and output conversion power and sensitive power based on the sensitivity test result; it is also used to set adjacent channel interference signals with increasing power, perform anti-interference test on the reference mobile phone, record the real-time signal value in the anti-interference test, calculate the real-time signal value, and output the signal disturbance value; the communication test module is also used to test the test mobile phone based on the sensitive power, output the limit strength, disturbance test value and expected disturbance value; calculate and analyze the limit strength, disturbance test value and expected disturbance value, and output the disturbance reference value and the sensitivity reference value;

[0064] The communication test module is configured with a sensitive detection strategy, which includes:

[0065] Get a mobile phone with normal signal reception function and mark it as the reference phone;

[0066] Perform receiving calculation processing, the receiving calculation processing includes:

[0067] Setting the radio frequency signal transmitter to transmit a signal at a first power, controlling the reference mobile phone to connect and transmit the signal, obtaining the signal strength received by the reference mobile phone, and marking it as a first strength;

[0068] Calculating the first intensity using a power conversion formula and outputting a received power;

[0069] The power conversion formula is configured as: Where P1 is the received power, DB1 is the first intensity;

[0070] In the specific implementation, the first power is set to 100mw, corresponding to a signal strength of 20dBm; the power of 100mw is the transmission power of a common wireless router, and the signal strength generated under this transmission power is relatively high, which can maintain the stability of the reference mobile phone receiving signal during the test;

[0071] It should be noted that in this solution, the signal strength of the mobile phone is expressed in dBm, and the calculation method of the mobile phone signal strength is DB1=10×lgP1; where lgP1 represents a logarithmic operation with a base of 10 on P1; and the signal strength of the mobile phone can be obtained using communication test software, and the inverse function operation of the signal strength calculation method, i.e., the power conversion formula, can be used to calculate the received power of the mobile phone;

[0072] For example, if the signal strength of a mobile phone is -30dBm, the received power of the mobile phone is calculated to be 0.001mw; then the ratio of the received power to the first power is calculated to obtain a receiving rate of one in ten thousand; it is normal that the received power is much smaller than the transmitted power, and the communication speed and stability of the mobile phone are both at an excellent level within the signal strength range of 0dBm to -50dBm;

[0073] Calculate the ratio of the received power to the first power, marked as a receiving rate;

[0074] Repeat the receiving calculation process of the first number to obtain the receiving rate of the first number;

[0075] In specific implementation, the first number is set to 3 times, and the reference mobile phone is tested 3 times. The average of the test results can avoid the situation where an accidental situation in one test leads to errors in subsequent analysis;

[0076] Calculate the average value of the received rate, labeled as conversion power;

[0077] Set the signal strength to DB2 of the second strength and the signal strength to DB3 of the third strength;

[0078] Use the limit calculation formula to calculate the conversion power and DB2, and output the limit power;

[0079] The limit calculation formula is configured as: Where P2 is the limit power and ZP is the conversion power;

[0080] The conversion power and DB3 are calculated using conventional calculation formulas, and conventional power is output;

[0081] The general calculation formula is configured as: Among them, P3 is the conventional power;

[0082] In specific implementation, the second strength is set to -70dBm and the third strength is set to -50dBm; the third strength is set to -50dBm because the mobile phone can use the communication function normally when the signal strength received is greater than or equal to -50dBm; when the signal strength is in the range of -50dBm to -70dBm, the communication speed and stability will decrease; when the signal strength of the received wireless signal is less than -70dBm, the communication speed will become slow and the stability cannot be guaranteed, so the second strength is set to -70dBm;

[0083] When the mobile phone receives a wireless signal with a signal strength of -50dBm, the receiving power of the mobile phone is 0.00001mw, and the conversion power of the mobile phone is one hundred thousandth, then the transmission power of the RF signal transmitter is 1mw; when the mobile phone receives a wireless signal with a signal strength of -70dBm, the transmission power of the RF signal transmitter is 0.01mw, which means that when the RF signal transmitter operates at a power less than or equal to the limit power of 0.01mw, the mobile phone cannot perform normal communication functions.

[0084] The communication test module is also configured with an interference detection strategy, which includes:

[0085] The reference mobile phone is tested for anti-interference, including:

[0086] The radio frequency signal transmitter is set to transmit a signal at a normal power, the initial power is set to 0, and the adjacent channel interference signal is incrementally increased by a second power at a first time interval;

[0087] In the specific implementation, the first time is set to 10s and the second power is set to 1mw; the first time is set to 10s in order to allow the mobile phone to stabilize the signal strength of the received signal when the signal strength of the adjacent channel interference signal changes suddenly; the second power is set to 1mw in order to provide an adjacent channel interference signal with a signal strength large enough to significantly interfere with the -50dBm signal strength currently received by the mobile phone;

[0088] Record the current signal strength of the mobile phone at the first interval and mark it as the real-time signal value;

[0089] In specific implementation, the transmission power of the adjacent channel interference signal is increased 1 second after the first real-time signal is recorded, and the second recording is performed 9 seconds after the power is increased, that is, 10 seconds after the first recording, and the subsequent recording operations are similar;

[0090] The real-time signal value is judged. When the real-time signal value is less than or equal to the second strength, the power of the current adjacent channel interference signal is obtained, marked as the maximum disturbance power, and the anti-interference test is stopped;

[0091] It should be noted that under the maximum disturbance power, the reference mobile phone will be disturbed from the normal communication state to the communication jam state. It is of no analytical value to continue the measurement, so the anti-interference test is stopped;

[0092] The absolute value of the difference between each real-time signal value and the first intensity is calculated and marked as the signal disturbance value.

[0093] The data analysis module is used to establish a scatter plot based on the signal disturbance value and the power of the adjacent channel interference signal, perform calculation and analysis on the scatter plot, and output the interference disturbance function;

[0094] See also Figure 3 As shown, Figure 3 It is a scatter plot of a possible situation, in which T1 is the interference disturbance function obtained after fitting a linear function of one variable.

[0095] The data analysis module is configured with function analysis strategies, which include:

[0096] A scatter plot is established with the horizontal axis being the signal disturbance value and the vertical axis being the power of the adjacent channel interference signal;

[0097] A linear function is fitted to the scattered points in the scatter plot, and the fitted function is marked as the interference disturbance function.

[0098] The communication test module is also equipped with a sensitive test strategy, which includes:

[0099] Perform a receiving power test on the test phone. The receiving power test includes:

[0100] Set the RF signal transmitter to transmit signals at the limit power, control the reference mobile phone to connect and transmit signals, obtain the signal strength received by the reference mobile phone, and mark it as the limit strength;

[0101] Calculate the ratio of the ultimate intensity to the second intensity and mark it as the sensitive reference value.

[0102] The communication test module is also configured with a disturbance test strategy, which includes:

[0103] Perform disturbance test on the test phone. The disturbance test includes:

[0104] Set the RF signal transmitter to transmit signals at normal power and control the test mobile phone to connect to the signal;

[0105] Randomly select a power less than the maximum disturbance power, mark it as the test power, substitute the test power into the interference disturbance function, and calculate the expected disturbance value;

[0106] Control the RF signal transmitter to transmit adjacent channel interference signals at the test power, obtain the current signal strength of the test mobile phone, and mark it as the test disturbance value;

[0107] Calculate the difference between the third intensity and the test disturbance value, and mark it as the disturbance phase difference value;

[0108] Calculate the ratio of the disturbance phase difference value to the expected disturbance value and mark it as the disturbance reference value.

[0109] The communication judgment module is used to calculate the disturbance reference value and the sensitive reference value, analyze the calculation results, and output communication judgment information based on the analysis results.

[0110] The communication judgment module is configured with a communication judgment strategy, which includes:

[0111] Calculate the sum of the disturbance reference value and the sensitive reference value, and mark it as the communication judgment value;

[0112] Compare the communication judgment value with the communication test threshold, and when the communication judgment value is greater than or equal to the communication test threshold, output normal communication information; when the communication judgment value is less than the communication test threshold, output bad communication information;

[0113] In the specific implementation, the communication test threshold is set to 1.8; in special cases, the disturbance reference value is 0.9, and the sensitivity reference value is 0.9. At this time, the sensitivity of the mobile phone receiving signal is 90% of the normal mobile phone level, and the anti-interference ability is also 90%. A 10% difference in each performance of the mobile phone is allowed, and the communication test threshold is obtained at this time.
