As shown in fig. 1, an embodiment of the present application provides a method for improving the NFC identification efficiency of an SOC chip, including:
step 100, receiving a radio frequency signal transmitted by an external device;
step 102, converting the radio frequency signal into radio frequency information;
104, generating feedback information according to the radio frequency information;
step 106, collecting current data to form a storage file when feedback information is generated according to radio frequency information each time; each storage file comprises currently received radio frequency information, current SOC chip position information and current feedback information;
and step 108, comparing the current position of the SOC chip with the position information in each storage file, marking the storage file as a transmitting file if the position of the SOC chip and the position information in the storage file are smaller than a preset distance, and transmitting feedback information in the transmitting file when receiving the radio frequency information which is the same as the radio frequency information in the transmitting file.
In this embodiment, the external device that transmits the radio frequency signal is often fixed in position, and the smart phone terminal that carries the SOC chip and the external device are substantially the same in position when near field communication is performed. When the SOC chip performs near field communication with external equipment each time, data of the communication are collected to form a storage file, and the storage file at least comprises radio frequency information received during the communication, current position information of the SOC chip and feedback information obtained through conversion. The SOC chip compares the position of the SOC chip with the position information in the storage file in real time, and a preset distance is set in advance. When the position of the SOC chip and the position of the position information are smaller than the preset distance, the SOC chip or the mobile phone terminal is proved to be close to the external equipment, and the storage file is marked as the transmitting file by the judging module. The transmitting file contains the feedback information generated by decoding and modulating the radio frequency information last time, and transmits the feedback information, and when the radio frequency information corresponding to the feedback information is received again, the feedback information is directly transmitted to complete near field communication. The setting of preset distance can be increased, so that the SOC chip needs longer time from the preset distance to the external equipment, and longer operation time is provided for comparing position information, so that the requirement on operation speed for comparing the position information is lower, the cost of the chip can be reduced, the occupied area of corresponding functional modules on the chip is reduced, and space is provided for improving the performance of other functional modules. In addition, the process of converting the radio frequency information into the feedback information has higher requirement on the operation speed, more complex operation process and larger operation amount, so that the power consumption and occupation are higher when the SOC chip performs the part of work, and the mobile phone can be blocked. According to the application, by collecting the storage file and comparing the position information, near field communication can be completed under the condition of bypassing the conversion of radio frequency information into feedback information, the identification efficiency of near field communication is improved, the cost of the SOC chip is reduced, and the power consumption of the terminal is reduced.
In some embodiments of the present application, after marking the stored file as a transmitted file, further comprising:
stopping comparing the current position of the SOC chip with the position information in each stored file, and starting timing;
and after the timing reaches the preset time, the current position of the SOC chip is compared with the position information in each stored file again.
In this embodiment, after the marking operation is completed, the process of comparing the position information may be stopped, thereby saving calculation power and energy consumption. After the position information comparison is completed, the position comparison is not needed again in a short time, so that the process can be stopped, and when the position comparison is needed again after the preset time is reached, the position information comparison process is automatically awakened. After the transmitted file is obtained by marking, only when the received radio frequency information is received, judging whether the received radio frequency information is the same as the radio frequency information in the transmitted file, wherein the step only needs to compare two files once, the comparison can be completed instantaneously with low consumption, and if the two radio frequency information are the same, the feedback information of the transmitted file can be transmitted directly; if the information is different, generating feedback information according to the radio frequency information, and transmitting the feedback information.
When receiving radio frequency information to perform near field communication, the two files which are almost free of consumption and instantaneous are compared at one time, and if the files are the same, feedback information can be directly transmitted to complete communication; if not identical, the present application also provides for a number of comparative operations with little consumption compared to the prior art.
In some embodiments of the present application, after marking the stored file as a transmitted file, further comprising:
after receiving the radio frequency information, judging whether the received radio frequency information is the same as the radio frequency information in the transmitting file;
if the feedback information is the same, transmitting the feedback information in the transmitting file;
if the information is different, generating feedback information according to the radio frequency information, and transmitting the feedback information.
In this embodiment, in order to avoid that after receiving the radio frequency information, the process of comparing the position information and the process of converting the radio frequency information into the feedback information are performed simultaneously, and then both processes obtain respective feedback information, which may cause the transmitting module to not know which feedback information to transmit, and meanwhile, the consumption of the converting process is relatively large during operation, which may also cause the terminal to be stuck or scalded. Therefore, when the radio frequency information is received, the position comparison process with small consumption and high speed works preferentially, and the process of generating the feedback information according to the radio frequency information can be performed only when the received radio frequency information is different from the radio frequency information in the transmitting file.
In some embodiments of the application, further comprising:
each time a new transmitted file is marked, the mark of the old transmitted file is deleted to make it a stored file.
In this embodiment, only one transmitting file needs to be marked in one near field communication, and when the SOC chip moves from the vicinity of one external device to another external device, new feedback information may be generated, and at this time, the new feedback information may replace the old feedback information.
In some embodiments of the present application, the stored file further includes time information;
before comparing the current position of the SOC chip with the position information in each storage file, the method further comprises the following steps:
comparing the current time of the SOC chip with the time information in each stored file;
judging whether the time difference between the current time of the SOC chip and the time information in the stored file is smaller than the preset time;
and only when the time difference is smaller than the preset time, the step of comparing the current position of the SOC chip with the position information in each storage file is executed.
Near field communication of mobile phone terminals is mostly applied to scenes such as resident entrance guard, company entrance guard or subway card swiping, so that the service time of the mobile phone terminal is fixed. In order to determine in time whether the position of the SOC chip is close to the external device, the position determination needs to be performed constantly. Therefore, in order to save consumption, each time data is collected to form a storage file, current time information is also required to be collected. Before the position determination is performed, a time determination is required, and the position determination process is awakened only when the current time is close to the time of the time information in the stored file. The time judgment of the SOC chip is basically free from consumption, and is equivalent to an alarm clock with fixed time periods set according to the time information in the stored file, wherein the fixed time periods are preset time, and the position judgment process of continuously acquiring and refreshing the current position information is awakened after the fixed time periods are entered.
In some embodiments of the present application, after collecting current data to form a storage file each time feedback information is generated according to radio frequency information, the method further includes:
each time a new storage file is acquired, comparing the new storage file with the storage file acquired before, deleting the new storage file if the new storage file is the same as the storage file acquired before, marking the storage file before once, and storing the new storage file if the new storage file is different from the storage file acquired before;
when the marking times of the stored files reach the preset times, marking the stored files reaching the preset times as comparison files;
comparing the current position of the SOC chip with the position information in each stored file, wherein the method comprises the following steps:
and comparing the current position of the SOC chip with the position information in each storage file marked as a comparison file.
In order to reduce the number of comparison and judgment of the position information, each time a new storage file is acquired, the new storage file is required to be compared with the storage file stored before, if the new storage file is the same as the storage file stored before, the storage file is marked once, and when the number of marking times of the storage file reaches a preset value, the near field communication is proved to have higher and more fixed use frequency. And marking the stored file with the marking times reaching a preset value as a comparison file, and performing comparison judgment only with the stored file marked as the comparison file when the position information is compared. The number of times of judgment by the judgment module is reduced through screening of the marking unit.
It should be noted that, when a new storage file is acquired and needs to be compared with an old storage file, the compared data may not include time information, or the time information may be subjected to a fuzzy process, that is, the time information of the new storage file and the time information of the old storage file may be considered to be the same within a fixed range.
In some embodiments of the present application, after marking the stored file up to the preset number of times as the comparison file when the number of times of marking the stored file up to the preset number of times reaches the preset number of times, the method further includes:
after marking the comparison file, starting timing the comparison file;
when the comparison file is marked as a transmission file, refreshing and timing;
and deleting the comparison file when the timing reaches a preset period.
In this embodiment, if the life scene of the end user changes, the stored file may not be used any more in a short time, so that in order to clean the storage space and reduce the comparison times, the comparison file which is not marked as the transmitted file for a long time is deleted, and it is noted that the deletion is not the marking of the comparison file, but the marking and the stored file are all deleted.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and are not limiting; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application.
