Description

Technical Field

[0001] The present invention relates to the technical field of data cables, and particularly to a safe data cable for intelligently detecting the communication state of a mobile terminal and a detection method therefor. Background Art

[0002] With the continuous increase in the number of mobile phone products, events such as short circuits, explosions, and burns caused by mobile phone charging occur every year, and mobile phone charging safety has also become a problem that attracts public attention. In order to reduce the aforementioned risks, safe data cables with temperature detection, overcurrent control, and power-off when fully charged have emerged in the prior art. However, these methods do not well solve the scenario where the user's head is closest to the mobile phone when the mobile phone is in a call state. In addition, during thunderstorms, using a mobile phone while it is charging significantly increases the risk of being struck by lightning, which affects the physical health of the user.

[0003] Therefore, in this patent application, the applicant has carefully studied a safe data cable for intelligently detecting the communication state of a mobile terminal and a detection method therefor to solve the above problems. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned prior art, the main purpose of the present invention is to provide a safe data cable for intelligently detecting the communication state of a mobile terminal and a detection method therefor, which has a high degree of intelligence, reduces misjudgment, has good safety, and effectively avoids damage to the mobile terminal or harm to the physical health of the user when the mobile terminal is in a call state during charging.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A safe data cable for intelligently detecting the communication state of a mobile terminal includes

[0007] a charging module for charging the mobile terminal;

[0008] a detection module for detecting the corresponding frequency of the current communication band if an incoming call or an outgoing call is detected for the mobile terminal being charged;

[0009] a main control module for coordinating and controlling the operation of the charging module, the comparison module, and the counting module;

[0010] a comparison module for comparing the corresponding frequency of the current communication band with a preset communication band threshold;

[0011] a counting module for counting the number of judgment times of the comparison module and counting the number of communication times when the corresponding frequency of the current communication band is within the preset communication band threshold;

[0012] When the cumulative number of judgment times recorded by the counting module does not reach the preset number of judgment times, the main control module outputs a corresponding delay signal. The detection module increases the corresponding number of detections according to the delay signal. When the cumulative number of judgment times recorded by the counting module reaches the preset number of judgment times, the delay signal is not output.

[0013] The main control module is respectively connected to the charging module, the comparison module and the counting module, and the detection module is connected to the comparison module.

[0014] As a preferred solution, the detection module is a radio frequency signal receiver with a receiving antenna and a signal processing circuit;

[0015] The radio frequency signal receiver is used to detect the frequency signal corresponding to the current communication frequency band when there is an incoming call access or an outgoing call in the mobile terminal, and send it to the signal processing circuit;

[0016] The signal processing circuit is used to receive the signal from the radio frequency signal receiver and send it to the comparison module after processing;

[0017] The signal processing circuit is respectively connected to the radio frequency signal receiver and the comparison module.

[0018] A detection method based on a safety data line for intelligently detecting the communication state of a mobile terminal includes:

[0019] When the mobile terminal is in the charging state, if there is an incoming call access or an outgoing call in the mobile terminal, the detection module detects the frequency corresponding to the communication frequency band;

[0020] The comparison module compares the frequency corresponding to the current communication frequency band collected by the detection module with the preset communication frequency band threshold. If the frequency corresponding to the current communication frequency band is within the preset communication frequency band threshold, the main control module controls the detection module to start the first delay detection. If the frequency corresponding to the current communication frequency band is not within the preset communication frequency band threshold, continue charging;

[0021] In the first delay detection, if the frequency corresponding to the communication frequency band is still within the preset communication frequency band threshold, the counting module accumulatively counts the number of judgment times and the number of communications, the main control module outputs a corresponding delay signal, and the detection module increases the corresponding number of detections according to the delay signal;

[0022] When the cumulative number of judgment times recorded by the counting module reaches the preset number of judgment times and the cumulative number of communications reaches the preset number of judgment times, the main control module controls the charging module to stop charging the mobile terminal; at the same time, the main control module controls the detection module to start the second delay detection; if the frequency corresponding to the communication frequency band is not within the preset communication frequency band threshold, continue charging again;

[0023] In the second delay detection, if the frequency corresponding to the communication frequency band is still within the preset communication frequency band threshold, the main control module controls the charging module to maintain the stopped charging state.

[0024] As a preferred solution, when the cumulative judgment times recorded by the counting module reach the preset judgment times, the counting of the counting module is cleared.

[0025] As a preferred solution, the preset communication frequency band threshold is 800 MHz to 1800 MHz.

[0026] As a preferred solution, the time interval range of the first delay detection is 20 seconds to 70 seconds.

[0027] As a preferred solution, the time interval of the first delay detection is 20 seconds, and the cumulative judgment times are 3 times. If the cumulative communication times reach the cumulative judgment times, the main control module controls the charging module to stop charging the mobile terminal.

[0028] As a preferred solution, the time of the second delay detection is greater than the time of the first delay detection.

[0029] As a preferred solution, the time interval range of the second delay detection is 5 minutes to 20 minutes.

[0030] As a preferred solution, the time interval of the second delay detection is 5 minutes. If the frequency corresponding to the communication frequency band is within the preset communication frequency band threshold, the main control module controls the charging module to maintain the stopped charging state.

[0031] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, when it is detected that the frequency corresponding to the current communication frequency band is within the preset communication frequency band threshold, after delay detection, it is further determined whether the mobile terminal enters the communication state, and then the charging is controlled to be maintained or stopped. The degree of intelligence is relatively high, the misjudgment is reduced, the safety is good, and it effectively avoids damage to the mobile phone or harm to personal health caused by the mobile terminal being in a call state during charging.

[0045] The present invention will be further described below in conjunction with the accompanying drawings and the detailed embodiment.

[0046] As Figure 1 and Figure 2 shown, a secure data cable for intelligently detecting the communication status of a mobile terminal includes

[0047] a charging module 12 for charging the mobile terminal; it should be noted that the mobile terminal can be a mobile phone, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), or an in-vehicle computer, etc. In this embodiment, the charging module 12 includes a power manager 121 and a mobile terminal power supply module 122. The power manager 121 is connected to the main control module 11, and the power manager is connected to the mobile terminal power supply module 122. The mobile terminal power supply module has a charging power maintenance sub-module for maintaining the charging power of the mobile terminal when the corresponding frequency of the communication band during an incoming call access or outgoing call of the mobile terminal is not within the preset communication band threshold;

[0048] a main control module 11 for coordinately controlling the operation of the charging module 12, the comparison module 14, and the counting module 15;

[0049] a detection module 13 for detecting the corresponding frequency of the current communication band if it detects an incoming call access or outgoing call of a mobile terminal that is being charged;

[0050] a comparison module 14 for comparing the corresponding frequency of the current communication band with the preset communication band threshold;

[0051] a counting module 15 for counting the number of judgments of the comparison module 14 and counting the number of communication times when the corresponding frequency of the current communication band is within the preset communication band threshold;

[0052] It should be noted that the number of communications is determined by the result of comparing data, with an initial value of 0. When it is determined that the frequency corresponding to the current communication frequency band is within the preset communication frequency band threshold, the count is incremented by 1.

[0053] When the cumulative judgment count recorded by the counting module 15 does not reach the preset judgment count, the main control module 11 outputs a corresponding delay signal. The detection module 13 increases the corresponding detection count according to the delay signal. When the cumulative judgment count recorded by the counting module 15 reaches the preset judgment count, no delay signal is output.

[0054] In this embodiment, the main control module 11 is disposed in the end housings of the data line. Preferably, the main control module 11 is an IC chip and is disposed in the output end housing, that is, in the housing at the end where it is connected to the mobile terminal. The main control module 11 is respectively connected to the charging module 12, the comparison module 14, and the counting module 15, and the detection module is connected to the comparison module.

[0055] In this embodiment, the detection module 13 is a radio frequency signal receiver 131 with a receiving antenna and a signal processing circuit 132; the signal processing circuit 132 is respectively connected to the radio frequency signal receiver 131 and the comparison module 14.

[0056] The radio frequency signal receiver 131 is configured to detect the frequency signal corresponding to the current communication frequency band when there is an incoming call access or an outgoing call from the mobile terminal, and send it to the signal processing circuit 132; the receiving antenna of the radio frequency signal receiver 131 can be integrated on the main control module 11 or disposed on the back of the mobile phone.

[0057] The signal processing circuit 132 is configured to receive the signal from the radio frequency signal receiver 131 and process it and then send it to the comparison module 14.

[0058] After the data line is powered off, the records in the counting module 15 will be automatically cleared.

[0059] A detection method, which is based on the aforementioned safe data line for intelligently detecting the communication state of a mobile terminal, includes:

[0060] As Figure 2 shown, in the state of charging the mobile terminal, when there is an incoming call access or an outgoing call from the mobile terminal, the detection module detects the frequency corresponding to the communication frequency band.

[0061] The comparison module 14 compares the frequency corresponding to the current communication frequency band collected by the detection module 13 with the preset communication frequency band threshold. In this embodiment, the preset communication frequency band threshold is from 800 MHz to 1800 MHz.

[0062] If the frequency corresponding to the current communication frequency band is within the preset communication frequency band threshold, the main control module 11 controls the detection module 13 to start the first delay detection. If the frequency corresponding to the current communication frequency band is not within the preset communication frequency band threshold, continue charging.

[0063] In the first delay detection, if the frequency corresponding to the communication frequency band is still within the preset communication frequency band threshold, the counting module 15 accumulatively counts the number of judgments and the number of communications. The main control module 11 outputs a corresponding delay signal, and the detection module 13 increases the corresponding number of detections according to the delay signal. It should be noted that when the cumulative number of judgments recorded by the counting module 15 has not reached the preset number of judgments, the main control module 11 controls the charging module 12 to maintain the charging state.

[0064] When the cumulative number of judgments recorded by the counting module 15 reaches the preset number of judgments and the cumulative number of communications reaches the preset number of judgments (at the same time, the count of the counting module is cleared), the main control module 11 controls the charging module 12 to stop charging the mobile terminal. At the same time, the main control module 11 controls the detection module 13 to start the second delay detection. If the frequency corresponding to the communication frequency band is not within the preset communication frequency band threshold, continue charging again.

[0065] In the second delay detection, if the frequency corresponding to the communication frequency band is still within the preset communication frequency band threshold, the main control module 11 controls the charging module 12 to maintain the charging stop state. It should be noted that when the charging module 12 maintains the charging stop state, the main control module 11 will still start the cyclic second extension detection until the frequency corresponding to the communication frequency band is within the preset communication frequency band threshold, and the main control module 11 controls the charging module 12 to resume the charging state again.

[0066] In this embodiment, the time interval range of the first delay detection is 20 seconds to 70 seconds. Preferably, the time interval of the first delay detection is 20 seconds, and the cumulative number of judgments is 3 times. If the cumulative number of communications reaches the cumulative number of judgments, the main control module 11 controls the charging module 12 to stop charging the mobile terminal. The time of the second delay detection is greater than the time of the first delay detection.

[0067] The second delay detection is used to determine whether the call state has ended. The time interval range of the second delay detection is 5 minutes to 20 minutes. Preferably, the time interval of the second delay detection is 5 minutes. If the frequency corresponding to the communication frequency band is within the preset communication frequency band threshold, the main control module 11 controls the charging module 12 to maintain the charging stop state.

[0068] The key design point of the present invention is that when it is detected that the frequency corresponding to the current communication frequency band is at the preset communication frequency band threshold, after a delay detection, it is then determined whether the mobile terminal enters the communication state, and then the charging is controlled to be maintained or stopped. It has a high degree of intelligence, reduces misjudgment, has good safety, and effectively avoids damage to the mobile phone or harm to personal health caused by the mobile terminal being in a call state during charging.

[0069] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
