it should be noted that if the blank error rate of the first sim card is smaller than the blank error rate threshold, the collected blank error rate information is transmitted to the judging system and is secondarily judged by the main system, the collected blank error rate information is confirmed to be destroyed in the transmission process due to the fact that the signal voltage is not passed, further spot check judgment is carried out by the screening system, and the blank error rate information is confirmed to be correct and smaller than the threshold.
S3: and enhancing the received parameters which are not up to standard through a monitoring program.
Further, if the signal strength of the first sim card is smaller than the threshold value, the signal strength cannot reach the full-lattice signal strength, after the signal strength is primarily judged by the judging system and is transmitted to the main system for secondary judgment, the collected signal strength information is confirmed to be correct, the screening system intervenes in screening the collected signal strength, the condition that the signal strength has signal loss and signal blurring is confirmed, and the fault I1 is judged;
further, if the channel quality of the first sim card is smaller than the threshold value, the channel quality is poor, after the channel quality is primarily judged by the judging system and is transmitted to the main system for secondary judgment, the acquired channel quality is confirmed to be correct, the screening system intervenes in screening the acquired channel quality, the condition that the channel utilization rate of the channel quality is extremely low is confirmed, and the fault I2 is judged;
it should be noted that, if the time delay of the first sim card is greater than the threshold, the time delay is retained or advanced, and after being primarily determined by the determining system and transmitted to the main system for secondary determination, the collected time delay information is confirmed to be correct, the screening system intervenes to screen the collected time delay, and the condition that the time delay has unequal time is confirmed, and the fault I3 is determined;
further, if the blank error rate of the first sim card is greater than the threshold value, the accuracy of the transmitted data is reduced in a specified time, the transmitted data is primarily judged by the judging system and is transmitted to the main system for secondary judgment, the acquired blank error rate is confirmed to be free, the screening system intervenes to screen the acquired blank error rate, the condition that the signal is attenuated and destroyed in the transmission process is confirmed, and the fault I4 is judged.
Further, the enhancing the received parameters which are not up to standard comprises enhancing the signals of the faults I1 and I2 when the faults I1 and I2 occur, wherein the calculation formula is as follows,
K＝P×H+Z s
wherein K is enhanced parameter information, P is optimal parameter information which can be searched in the current scene, H is the optimal parameter information quantity which can be searched in the current scene, Z s,g The g optimal parameters are found at s time.
It should be noted that, if the parameter information is still lower than the parameter threshold after the fault I1 and the fault I2 are enhanced, the signal parameters, the signal strength and the channel quality corresponding to the fault I1 and the fault I2 are assigned.
Further, when faults I3 and I4 occur, the main system sends a maintenance instruction, the upper controller adjusts the internal faults through internal self-checking and enhances parameter information, and if signal parameters corresponding to the faults I3 and I4 are still higher than a parameter threshold value, the signal parameters corresponding to the faults I3 and I4, time delay and blank error rate are assigned.
It should be noted that, the signal intensity < the signal intensity threshold value is 9 minutes; the channel quality is less than the channel quality threshold value and is 7 minutes; the time delay is more than the time delay threshold value is 5 minutes; the air interface error rate is more than 3 minutes of the air interface error rate threshold value; the message parameter threshold is-120, the channel quality threshold is 12, the time delay threshold is 100ms, and the air interface error rate threshold is 10 -8 。
Furthermore, the monitoring program assigns a value to the received unqualified parameter, wherein the value of the signal strength < the signal strength threshold is 9 minutes, if the value of the signal strength is less than 9 minutes, the unknown condition of signal jitter occurs in the signal strength, and if the value of the signal strength is more than 9 minutes, the problem that the frequency difference of the signal occurs due to network deviation is too large, so that the value of the signal strength is set to be 9 minutes preferably.
Furthermore, if the channel quality score is set to be less than 7 minutes, the channel quality will have an extreme value due to channel fluctuation caused by signal reception fluctuation, and if the channel quality score is set to be more than 7 minutes, the problem that the channel quality has an excessive signal-to-noise ratio due to signal reception fluctuation will occur, which seriously affects the preliminary determination of the channel quality by the determination system, so that the score is set to be 7 minutes.
It should be noted that, if the time delay value is set to less than 5 minutes, the time delay will occur, the error rate of the time delay is greater than the time set in the system, and if the time delay value is set to greater than 5 minutes, the time delay will occur as a result of time retention, which is unequal to the time in the system and affects the response time of the determination system, so that it is preferable to set the value to 5 minutes.
Furthermore, if the blank error rate is greater than the air interface error rate threshold value and is 3 minutes, if the blank error rate score is set to be less than 3 minutes, the blank error rate can appear a large-scale signal blank, and if the blank error rate score is set to be less than 3 minutes, the situation that the blank error rate occurs frequently can be caused, and the sim card signal is seriously lost, so the score is set to be 3 minutes and is preferable.
S4: and when the total score is greater than the threshold value, intelligently switching sim cards.
Further, when the total score is greater than the threshold value, the automatic control monitoring program performs intelligent sim card switching, which includes comparing the obtained parameter information with the corresponding parameter threshold value each time, counting the total score of the received parameter information every five rounds, and when the total score is greater than the threshold value 60, satisfying the switching condition, wherein the first sim card is replaced by the second sim card.
It should be noted that, if the total score of the received parameter information is set to be less than or equal to the threshold 59, the transmitted parameter information is determined to be correct by the determining system, and after the parameter information is confirmed to be correct, the condition that the signal strength signal is lost and the quality of the channel is blurred occurs in the information parameter, so that the total score cannot be less than or equal to the threshold 59 score in actual operation.
Furthermore, if the number of detection settings is less than five, the signal parameters are too few to take values, and the values are not taken in a large range, so that the parameter information is inaccurately assigned, the situation of error assignment occurs, and finally the situation of misoperation occurs.
Furthermore, if the multiple rounds of value setting is greater than five rounds, the value time is too long, which affects the correct judgment of the system on the parameter information system, so that the time delay is unequal, the signal blank condition occurs, and finally the signal false alarm condition occurs.
