According to the near field communication terminal, near field communication can be completed under the condition of bypassing the information processing module through the cooperation of the acquisition module, the judgment module and the transmitting module, the recognition efficiency of the 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 invention, the receiving module further includes a conversion module, and the receiving module includes a first receiving unit and a second receiving unit, where the first receiving unit is configured to receive the radio frequency signal and transmit the radio frequency signal to the conversion module, and the conversion module is configured to convert the radio frequency signal into radio frequency information and transmit the radio frequency information to the second receiving unit.
In this embodiment, the conversion module may extract voltage information of the received radio frequency signal, and generate radio frequency information according to the voltage information and the calibration voltage. The first receiving unit of the receiving module firstly receives the radio frequency signal transmitted by the external equipment, and transmits the radio frequency signal to the conversion module for conversion, the conversion module converts the radio frequency signal to obtain radio frequency information, and transmits the radio frequency information to the second receiving unit, and the second receiving unit transmits the radio frequency information to the information processing module.
In some embodiments of the present invention, the transmitter is further included, and the conversion module is further configured to convert the feedback information transmitted by the transmission module into a feedback signal, and transmit the feedback signal to the transmitter for transmission.
In this embodiment, the radio frequency information transmitted by the transmitting module is converted into a radio frequency signal by the converting module and transmitted by the transmitter.
In some embodiments of the invention, a signal amplifier is also included for enhancing the feedback signal and the radio frequency signal.
In this embodiment, the signal amplifier is capable of enhancing both the feedback signal and the radio frequency signal.
In some embodiments of the invention, the transmitting module includes a pre-transmitting unit and a transmitting unit;
the pre-transmitting unit is used for receiving and storing feedback information sent by the judging module;
the judging module is further used for judging whether the radio frequency information received by the receiving module is identical to the radio frequency information in the transmitting file when the feedback information is stored in the pre-transmitting unit, if so, the transmitting unit transmits the feedback information in the pre-transmitting unit, and if not, the starting information processing module generates the feedback information according to the radio frequency information and transmits the feedback information to the transmitting unit for transmission.
In this embodiment, when the receiving unit receives the radio frequency information, the wake-up judging module immediately judges whether the received radio frequency information is the same as the radio frequency information in the transmitting file, and the step only needs one comparison of the two files, so that the comparison can be completed instantaneously with low consumption, and if the two radio frequency information are the same, the feedback information of the pre-transmitting unit can be directly transmitted through the transmitting unit; if the feedback information is different, the restarting information processing module generates feedback information according to the radio frequency information and transmits the feedback information to the transmitting unit for transmission.
When receiving radio frequency information to perform near field communication, the judging module is used for comparing two files which are almost free of consumption and instantaneous at one time, and if the files are the same, feedback information can be directly transmitted to complete communication; unlike the prior art, the present application also only provides a number of nearly consumable comparative operations.
In some embodiments of the present invention, the system further includes a wake-up module, the wake-up module is electrically connected with the determination module and the information processing module, when the determination module determines that the radio frequency information received by the receiving module is different from the radio frequency information in the transmission file, the determination module sends a wake-up instruction to the wake-up module, the wake-up module wakes up the information processing module after receiving the wake-up instruction, and when the wake-up module does not wake up the information processing module, the information processing module is in a sleep state.
In this embodiment, in order to avoid that the receiving module receives the radio frequency information, the determining module and the information processing module work simultaneously, if both modules obtain respective feedback information, the transmitting module may not know which feedback information to transmit, and meanwhile, the information processing module consumes a relatively large amount of power during working, which may also cause the terminal to be blocked or scalded. Therefore, the wake-up module is arranged, when the receiving module receives the radio frequency information, the judging module with low consumption and high speed works preferentially, only when the judging module judges that the radio frequency information received by the receiving module is different from the radio frequency information in the transmitting file, the judging module sends a wake-up instruction to the wake-up module, the wake-up module wakes up the information processing module after receiving the wake-up instruction, and when the wake-up module does not wake up the information processing module, the information processing module is in a dormant state.
In some embodiments of the present invention, the pre-transmit unit has an update function to delete old feedback information in the pre-transmit unit each time the pre-transmit unit receives new feedback information.
In this embodiment, the pre-transmitting unit only needs to store one feedback information, 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 invention, the storage file further includes current time information, the determination module includes a time determination unit and a position determination unit, the time determination unit is used for comparing the current time of the SOC chip with the time information in each storage file, and the position determination unit is used for comparing the current position of the SOC chip with the position information in each storage file;
when the time difference between the current time of the SOC chip and the time information in the storage file is smaller than the preset time, starting the position judging unit, otherwise, judging the dormant position unit, after the position judging unit is started, 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 the preset distance, transmitting feedback information in the transmitting file to the transmitting module, and when the receiving module receives the radio frequency information which is the same as the radio frequency information in the transmitting file, transmitting the feedback information in the transmitting file by the transmitting module.
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. The determination module needs to continuously perform position determination in order to determine in time whether the position of the SOC chip is close to the external device. Therefore, in order to save consumption, the acquisition module also needs to acquire time information when the information processing module works, and the judging module comprises a time judging unit and a position judging unit, wherein the time judging unit is associated with the time information stored in the file by the acquisition module, and only when the current time is close to the time information stored in the file, the position judging unit is awakened. 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 unit which continuously acquires and refreshes the current position information is awakened after the fixed time periods are entered.
In some embodiments of the invention, the acquisition module comprises a marking unit and a storage unit;
the marking unit is used for collecting current data to form a storage file when the information processing module works each time, the marking unit is used for comparing the new storage file obtained by each time with the storage file collected before, deleting the new storage file if the new storage file is the same as the storage file data collected before, marking the previous storage file once, and storing the new storage file in the marking unit if the new storage file is different from the storage file data collected before;
when the marking times of the stored files in the marking unit reach the preset times, the marking unit transmits the stored files reaching the preset times to the storage unit, and the storage unit is used for providing the stored files for the judging module.
In order to reduce the times of comparison and judgment of the judging module, the collecting module comprises a marking unit and a storage unit, the marking unit firstly collects the data of the information processing module during working, and the collected storage file is firstly stored in the marking unit. When a new storage file is collected by the marking unit each time, the new storage file is required to be compared with the storage file stored before, if the new storage file is the same, the storage file is marked once, and when the marking times of the storage file reach a preset value, the near field communication is proved to have higher and fixed use frequency. Storing the storage file with the marking times reaching the preset value into a storage unit, and comparing and judging only with the storage file in the storage unit when the judging module judges. The number of times of judgment by the judgment module is reduced through screening of the marking unit.
It should be noted that, when the marking unit collects a new storage file 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 invention, the storage unit is provided with a collection period, when the storage file enters the storage unit, the timing is started, the timing is refreshed each time the storage file is marked as the emission file, if the storage file is not refreshed in the collection period, the storage file is deleted in the storage unit, and the storage file with the same data as the storage file in the marking unit is deleted.
In this embodiment, if the life scene of the end user changes, the marking unit and the storage file in the storage unit may not be used any more in a short time, so in order to clean the storage space, the comparison frequency is reduced, the storage file in the storage unit which is not marked as the transmission file for a long time is deleted, and the storage file in the marking unit which is the same as the data of the storage file is deleted.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention 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 invention.
