Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to solve the problems in the prior art, embodiments of the present invention provide a data line detection method, a terminal device, and a computer-readable storage medium. First, a data line detection method provided by an embodiment of the present invention is described below.

Fig. 1 is a schematic flow chart illustrating a data line detection method according to an embodiment of the present invention. As shown in fig. 1, the data line detection method applied to the terminal device includes:

s101, acquiring a first magnetic flux;

s102, if the first magnetic flux exceeds a first reference range, determining that the data line is a target data line;

In the embodiment of the present invention, the target data line is a non-original data line, that is, if it is determined that the data line is the target data line, it may be determined that the data line is a non-original data line.

Therefore, in the data line detection method according to the embodiment of the present invention, since the data line has the magnetic component, the terminal device can obtain the first magnetic flux of the data line in a state of being connected to the data line, and if the first magnetic flux exceeds the first reference range, it is determined that the data line is the target data line, which indicates that the data line is the non-genuine data line, and the data line does not pass the data line authentication, so that the fast determination of the non-genuine data line is achieved, the influence of the non-genuine data line on the charging and data transmission performance is avoided, the charging and data transmission speed and stability performance are ensured, and the user experience is improved. Meanwhile, the first magnetic flux of the terminal equipment in the connection state with the data line is detected, and only the magnetic part is required to be arranged at the data interface of the data line, so that the production cost of the original data line can be reduced.

In the embodiment of the invention, the magnetic part can be additionally arranged at the data interface of the data line, and the magnetic parts can be additionally arranged at the data interface of the data line and the wired data connection port of the terminal equipment at the same time, so long as the wired data connection port of the terminal equipment is in a magnetic field range under the condition that the terminal equipment is connected with the data line. Wherein, the magnetic part can be a permanent magnet, an electromagnet and the like.

In the embodiment of the invention, after the terminal equipment is connected with the data line, two working modes can be provided. Wherein, the first working mode is as follows: whether the data line is a non-original data line is judged first, and whether charging is carried out through the data line is confirmed according to the judgment result. The second working mode is as follows: the data line is directly charged through the data line, and whether the data line is a non-original data line or not is judged in the charging process. In the following, the two modes of operation will be described in detail:

first mode of operation

In the first operation mode, after the data interface of the data line is connected to the wired data connection port of the terminal device, the terminal device is in a state of being connected to the data line, and the magnetic field in the area near the wired data connection port of the terminal device changes.

At this time, whether the data line is the target data line or not can be quickly determined by judging whether the magnetic field intensity obtained by the terminal device is the same as the magnetic field intensity after the original data line is connected or not when the terminal device is in a state of being connected with the data line, so that quick data line authentication of the data line is realized.

From the hall effect it can be seen that when a current is perpendicular to an external magnetic field through the semiconductor, carriers in the semiconductor are deflected, an additional electric field is generated in the semiconductor in a direction perpendicular to the current and the magnetic field, so that a potential difference can be generated across the semiconductor, and by detecting the magnitude of this potential difference, the magnetic flux at the semiconductor can be determined, and thus the magnetic field strength at the semiconductor.

According to the corresponding relation between the magnetic field intensity and the magnetic flux, when the magnetic field intensity is increased, the magnetic flux passing through a fixed area of the terminal equipment at any position in the magnetic field range is increased; when the magnetic field strength decreases, the magnetic flux through the fixed area of the terminal device at any position within the range of the magnetic field also decreases.

Therefore, in the embodiment of the present invention, the principle of the hall effect may be utilized to detect the first magnetic flux to determine whether the terminal device is in a state of being connected to the data line, and whether the first magnetic flux acquired by the terminal device is the same as the first magnetic flux after the original data line is connected is determined, so as to quickly determine whether the data line is the target data line.

In step S101 of the embodiment of the present invention, a first sampling point for acquiring the first magnetic flux may be disposed near the wired data connection port of the terminal device, and a first magnetic flux sensor may be disposed at the first sampling point to acquire the first magnetic flux, so as to sense whether the first magnetic flux at the first sampling point meets a requirement when the terminal device is in a state of being connected to the data line.

In some embodiments of the invention, the first magnetic flux sensor may be a hall sensor. In other embodiments of the present invention, the first magnetic flux sensor may also be a geomagnetic sensor.

Taking the first magnetic flux sensor as an example, when the data interface of the data line is close to the wired data connector, the hall sensor can sense the magnetic flux change of the magnetic field caused by the approach of the magnetic part at the data interface, and after the data interface is connected with the wired data connector, the magnetic flux of the magnetic field sensed by the hall sensor is not changed any more, and at the moment, the magnetic flux detected by the hall sensor is the first magnetic flux of the terminal equipment in the state of being connected with the data line.

In step S101 of the embodiment of the present invention, the first magnetic flux may be an actual magnetic flux detected by the terminal device, and the first magnetic flux may also be a first difference value between the actual magnetic flux detected by the terminal device and a preset reference magnetic flux.

In step S102 of the embodiment of the present invention, when the first magnetic flux is an actual magnetic flux detected by the terminal device, if the actual magnetic flux is beyond the first reference range, it is determined that the data line is the target data line. When the first magnetic flux is a first difference value between an actual magnetic flux detected by the terminal device and a preset reference magnetic flux, if the first difference value exceeds a first reference range, the data line is determined to be the target data line.

Taking the first magnetic flux as an example of the actual magnetic flux detected by the terminal device, the fact that the actual magnetic flux exceeds the first reference range means that the actual magnetic flux is greater than the maximum value of the first reference range or less than the minimum value of the first reference range, at this time, it may be determined that the magnetic member on the data line is different from the magnetic member of the original data line, and therefore, it may be determined that the data line is the target data line, that is, the data line is the non-original data line.

Taking the first reference range as the reference range corresponding to the actual magnetic flux detected by the terminal device as an example, since the magnetic field intensity of the magnetic member on the original data line is fixed, the actual magnetic flux detected by the terminal device in the state that the terminal device is connected with the data line is also fixed, and before the terminal device leaves the factory, the actual magnetic flux detected by the terminal device in the state that the terminal device is connected with the original data line is calibrated to obtain the first reference range, and the first reference range is preset in the terminal device.

In the embodiment of the present invention, a calibration method of a reference range corresponding to a first difference between an actual magnetic flux detected by a terminal device and a preset reference magnetic flux is similar to a calibration method of a reference range corresponding to an actual magnetic flux detected by a terminal device, and is not described herein again.

In the embodiment of the present invention, after the first magnetic flux is acquired, if it is determined that the first magnetic flux is within the first reference range, it may be determined that the data line is not the target data line.

Specifically, when the first magnetic flux is an actual magnetic flux detected by the terminal device, if the actual magnetic flux is within the first reference range, it is determined that the data line is not the target data line. When the first magnetic flux is a first difference value between an actual magnetic flux detected by the terminal device and a preset reference magnetic flux, if the first difference value is within a first reference range, the data line is determined not to be the target data line.

Taking the first magnetic flux as an example of the actual magnetic flux detected by the terminal device, the fact that the actual magnetic flux is within the first reference range means that the actual magnetic flux is less than or equal to the maximum value of the first reference range and greater than or equal to the minimum value of the first reference range, at this time, it can be determined that the magnetic member on the data line is the same as the magnetic member of the original data line, and therefore, it can be determined that the data line is not the target data line, that is, the data line is the original data line.

Second mode of operation

In the second operation mode, it can be known from the hall effect that the charging current also has a certain influence on the magnetic field intensity when the terminal device is charged through the data line. As can be seen from the correspondence between the magnetic field intensity and the magnetic flux, the change in the magnetic field intensity of the magnetic field can be determined by the change in the magnetic flux, and the charging current of the data line can be obtained.

At this time, in step S101 of the embodiment of the present invention, the first magnetic flux is specifically a magnetic flux acquired by the terminal device when the terminal device is in a connected state with the data line and the terminal device is in a charging state. That is, the first magnetic flux refers to a magnetic flux influenced by the charging current. Specifically, the method for acquiring the first magnetic flux is similar to that in the first operating mode, and is not described herein again.

In step S102 of the embodiment of the present invention, there are various methods of determining whether the data line is the target data line according to the first magnetic flux. For example, whether the data line is a target data line is determined by determining whether the first magnetic flux is within a first reference range. For another example, it is determined whether the data line is the target data line by determining whether a first difference between the first magnetic flux and the magnetic flux generated by the first magnetic member is within a first preset difference range.

In the second working mode, the calibration method for the first reference range is similar to the calibration method in the first working mode, and since the magnetic field strength of the magnetic part on the original data line is fixed and the charging current of the original data line is fixed, the first magnetic flux of the terminal device connected with the data line and in the charging state of the terminal device is also fixed, before the terminal device leaves the factory, the calibration can be performed according to the magnetic flux of the terminal device connected with the data line and in the charging state of the terminal device, so as to obtain the first reference range, and the first reference range is preset in the terminal device, which is not described herein again.

In the second operation mode, the principles of various determination methods for determining whether the data line is the target data line according to the first magnetic flux are similar to those in the first operation mode, and are not described herein again.

In the embodiment of the invention, the data wire is preferably a magnetic data wire.

Magnetism is inhaled formula data line and terminal equipment's connected mode and is inhaled the formula and be connected for magnetism, and its specific principle is: the periphery of the wired data connector of the terminal equipment is provided with the magnetic part, the periphery of the data interface of the magnetic type data line is provided with the magnetic part matched with the position and the size of the magnetic part of the terminal equipment, and when the data interface of the magnetic type data line is close to and contacts with the wired data connector of the terminal equipment, the data interface and the wired data connector are tightly connected and keep the relative position fixed through the attraction force between the two magnetic parts. When the data interface and the wired data connecting port are close to each other, the magnetic field intensity can be increased due to the fact that the two magnetic fields in the same direction are close to each other, and the magnetic field intensity of the wired data connecting port is increased.

In order to reduce the cost, the precision of the manufacturing process of the non-original data line is generally low, and when the magnetic data line is the non-original data line, the adopted material and the size of the element of the magnetic data line are generally different from those of the original data line.

Taking the magnetic part arranged at the data interface as an example, in order to avoid the interference of a magnetic field to terminal equipment, the magnetic part on the original data line is manufactured more finely, and the size of the magnetic part on the original data line can be reduced as much as possible on the premise of ensuring the attraction force between the magnetic part and the magnetic part at the wired data interface. The non-original data line is low in precision of the manufacturing process, and in order to reduce interference of a magnetic field to terminal equipment, the situation that the size is too small may occur, so that the attraction force between the two magnetic parts is insufficient. In addition, the precision of the manufacturing process of the non-original data line is low, so that the situation of overlarge size can occur in order to ensure the attraction force between the non-original data line and the magnetic part at the wired data connection port, and the magnetic field intensity of the magnetic part on the original data line is overlarge.

Therefore, after the non-original data line is connected with the terminal equipment, the magnetic field intensity of the wired data connection port is different from that when the original data line is connected with the terminal equipment, and the magnetic data line can be rapidly detected by utilizing the principle to determine whether the magnetic data line is a target data line, namely whether the magnetic data line is the non-original data line.

When the data line is a magnetic data line, and the first magnetic flux is an actual magnetic flux detected by the terminal device, the actual magnetic flux is a magnetic flux corresponding to a magnetic field formed by superimposing the first magnetic member and the second magnetic member; when the first magnetic flux is a first difference value between an actual magnetic flux detected by the terminal device and a preset reference magnetic flux, the reference magnetic flux may be a magnetic flux corresponding to a magnetic field of the first magnetic member, and the first difference value is a difference value between a magnetic flux corresponding to a magnetic field formed by superimposing the first magnetic member and the second magnetic member and a magnetic flux corresponding to a magnetic field of the first magnetic member.

Because when the data line is for magnetic type data line, only utilize its self magnetism spare both can realize its quick detection, need not additionally to increase magnetism spare, consequently, can further reduce the manufacturing cost of the data line that has data line authentication function.

Further, when the data line is a magnetic-type data line, taking the first magnetic flux as an example of an actual magnetic flux detected by the terminal device, the method for calibrating the first reference range by using the original data line includes:

detecting whether the magnetic type data line connected with the wired data connector is normally connected;

and if the connection is normal, reading the current output value of the first magnetic flux sensor, and generating a first reference range according to the output value and a preset error range. If the connection is abnormal, the magnetic type data line is prompted to be adjusted to enable the magnetic type data line to be connected with normal prompt information.

For example, if the first magnetic flux sensor detects that the magnetic flux generated by the first magnetic member of the terminal device is 80Wb, the first magnetic flux sensor detects that the first magnetic flux of the terminal device in a state of being connected to the data line is 100Wb, and the set error range is ± 5Wb, at this time, the calibrated first reference range is 95-105 Wb.

In the embodiment of the invention, after the data line is determined to be the target data line, the terminal device can be controlled to generate the prompt message, so that the user can know that the data line adopted by the user is the non-original data line. The prompting information may prompt the user only once after the data line is determined to be the target data line, or may prompt the user multiple times after the data line is determined to be the target data line.

Fig. 2 is a schematic flow chart illustrating a data line detection method according to another embodiment of the present invention. As shown in fig. 2, after determining that the data line is the target data line, the data line detecting method further includes:

s103, detecting the charging current passing through the data line;

s104, if the charging current is larger than or equal to a preset current value, controlling the terminal equipment to charge through a data line;

and S105, if the charging current is smaller than the preset current value, controlling the terminal equipment to generate prompt information.

In step S103 of the embodiment of the present invention, in the first operation mode, after determining that the data line is the target data line, it is not directly rejected to perform charging through the data line, but it is determined whether the data line supports a charging protocol corresponding to the terminal device, for example, a fast charging protocol, and then it is determined whether to perform charging through the data line according to a determination result.

Taking a charging protocol corresponding to the terminal device as an example of a fast charging protocol, the charging current passing through the data line may be detected, if the charging current is greater than or equal to a preset current value corresponding to the fast charging protocol, it may be determined that the data line supports the fast charging protocol, and if the charging current is less than the preset current value, it may be determined that the data line does not support the fast charging protocol. The detected charging current may be an instantaneous current value, an average value of current values in a predetermined time period, or a maximum value of current in the predetermined time period, where the predetermined time period may be 1 s.

In step S104 of the embodiment of the present invention, if the charging current is greater than or equal to the preset current value, it may be determined that the data line supports the charging protocol corresponding to the terminal device, which indicates that the terminal device may be temporarily charged by using the charging protocol, so that the terminal device may be controlled to be charged through the data line, so as to meet the requirement of the user for charging the terminal device.

In step S105 of the embodiment of the present invention, if the charging current is less than the preset current value, it is determined that the data line does not support the charging protocol corresponding to the terminal device, which indicates that the terminal device cannot be temporarily charged by using the charging protocol, so that the terminal device is not controlled to be charged, and a prompt message for prompting a user to replace the data line can be generated, so that the user knows that the adopted data line is a non-original data line, and the data line does not have the charging protocol corresponding to the terminal device, and cannot charge the terminal device through the data line.

Therefore, in the embodiment of the present invention, although it is determined that the data line fails to pass the data line authentication according to the first magnetic flux and is the target data line, the terminal device can still be charged as long as the data line supports the charging protocol corresponding to the terminal device, so that it is ensured that the charging requirement of the user on the terminal device is met before the user replaces the original data line, so as to improve the user experience.

In the embodiment of the present invention, the preset current value is preset according to a current value corresponding to a charging protocol supported by the terminal device before the terminal device leaves a factory.

Although the non-genuine data line supports the charging protocol corresponding to the terminal device, since the material and size of the components thereof are different from those of the genuine data line, the charging effect cannot be guaranteed, and for example, a situation in which the charging current is unstable may occur, thereby causing a problem in that the charging speed is unstable or the charging is frequently interrupted.

Fig. 3 is a schematic flow chart illustrating a charge detection method according to an embodiment of the present invention. As shown in fig. 3, after the control terminal device is charged through the data line, the data line detection method further includes:

s201, acquiring charging current passing through a data line at intervals of first preset time;

s202, if the charging current is within a preset current range, continuing to charge;

and S203, if the charging current exceeds the preset current range, generating prompt information.

In step S201 of the embodiment of the present invention, the charging current passing through the magnetic data line may be acquired by the current detection element connected to the wired data connection port at first predetermined time intervals during the charging process (i.e., periodically during the charging process), so that whether the charging current is stable and whether the charging process is interrupted may be monitored in real time.

In step S202 of the embodiment of the present invention, if the charging current is always within the preset current range, it indicates that the charging current is stable, and the charging can be continued without performing other actions.

In step S203 of the embodiment of the present invention, if the charging current exceeds the preset current range, specifically, the charging current may be higher than the maximum value of the preset current range or lower than the minimum value of the preset current range, a prompt message is generated to notify the user that the charging current is not the original data line, and the charging effect is not good, so that the user can timely know and replace the original data line.

In the embodiment of the present invention, the preset current range may be determined based on a preset current value, for example, the preset current range may be determined according to the preset current value and an allowable current floating range.

It should be noted that, if the charging current exceeds the preset current range, the charging may be continued and the prompt message may be generated, and the charging may also be stopped and the prompt message may be generated, so as to prevent the terminal device from being damaged due to the unstable charging current.

Therefore, in the embodiment of the invention, the charging effect of the non-original data line can be detected by regularly detecting whether the charging current passing through the data line always accords with the preset current range corresponding to the charging protocol corresponding to the terminal equipment, so that a user can timely know and replace the original data line when the charging effect is poor, and the damage to the terminal equipment caused by the unstable charging current is avoided.

In the embodiment of the invention, although the data line is determined to be the target data line according to the first magnetic flux, in order to meet the data transmission requirement of the user, data transmission can still be performed through the data line, so as to improve the user experience. However, since the elements of the non-genuine data line are different in material and size from the genuine data line, the data transmission may not be effective, for example, the data transmission speed may not be stable, resulting in problems of long data transmission time, low data transmission efficiency, or frequent interruption of data transmission.

Fig. 4 is a schematic flow chart illustrating a data line detection method according to another embodiment of the present invention. As shown in fig. 4, after determining that the data line is the target data line, the data line detection method further includes:

s106, acquiring the transmission speed of data transmission at intervals of a second preset time interval in the process of data transmission of the terminal equipment through the data line;

s107, if the transmission speed is within the preset speed range, continuing data transmission;

and S108, if the transmission speed exceeds the preset speed range, generating prompt information.

In step S106 of the embodiment of the present invention, the transmission speed of data transmission may be obtained every second predetermined time interval during the data transmission (i.e. periodically during the data transmission), so as to monitor whether the data transmission is stable and whether the data transmission is interrupted in real time.

In step S107 in the embodiment of the present invention, if the transmission speed is always within the preset speed range, it indicates that the data transmission is stable, and the data transmission can be continued without performing other actions.

In step S108 of the embodiment of the present invention, if the transmission speed exceeds the preset speed range, specifically, the transmission speed may be higher than the maximum value of the preset speed range or lower than the minimum value of the preset speed range, a prompt message is generated to notify the user that the data line is not an original data line, and the data transmission efficiency is low, so that the user can timely know and replace the original data line.

In the embodiment of the present invention, the preset speed range may be determined based on the preset transfer speed, and for example, the preset speed range may be determined according to the preset transfer speed and the allowable current floating range. Wherein, the preset transmission speed is the transmission speed of the original data line.

It should be noted that, if the transmission speed exceeds the preset speed range, the data transmission may be continued and the prompt information may be generated, or the data transmission may be stopped and the prompt information may be generated.

In the embodiment of the invention, the preset speed range is obtained by utilizing the calibration of an original data line and is preset in the terminal equipment before the terminal equipment leaves a factory. Specifically, the calibration method of the preset speed range is similar to the first reference range, and is not described herein again.

Therefore, in the embodiment of the invention, the data transmission effect of the non-original data line can be detected by regularly detecting whether the transmission speed of the data transmission always accords with the preset speed range, and when the data transmission effect is not good, a user can timely know and replace the original data line, so that the user experience is improved.

Although, in the aforementioned first operation mode, the data line may be authenticated to some extent by using the first magnetic flux to determine whether the data line is the target data line, since the magnetic member of some non-genuine data lines may be the same as the magnetic member of the genuine data line, it may not be possible to accurately determine whether the data line is the genuine data line based on only the first magnetic flux.

Fig. 5 is a schematic flow chart illustrating a data line detection method according to still another embodiment of the present invention. As shown in fig. 5, after determining that the data line is not the target data line in step S109, the data line detecting method further includes:

s110, acquiring a second magnetic flux;

s111, if the second magnetic flux is in a second reference range, determining that the data line passes through load current verification;

and S112, if the second magnetic flux exceeds the second reference range, determining that the data line fails to pass the load current verification.

As can be seen from the above analysis, when the terminal device is charged, the charging current also affects the magnetic field in the vicinity of the wired data connection port. Therefore, the charging current of the data line can be determined by detecting the second magnetic flux by utilizing the principle of the hall effect, so that whether the data line passes the load current verification can be determined, and whether the data line is the original data line can be further judged.

In step S110 of the embodiment of the present invention, a second sampling point for collecting a second magnetic flux may be disposed near the wired data connection port of the terminal device, and a second magnetic flux sensor may be disposed at the second sampling point to collect the second magnetic flux, so as to determine whether the maximum load current of the data line meets a preset requirement. In order to improve the detection precision and accuracy, the second sampling point may be disposed at a position close to the charging wire of the data line.

In some embodiments of the invention, the second magnetic flux sensor may be a hall sensor. In other embodiments of the present invention, the second magnetic flux sensor may also be a geomagnetic sensor.

In step S110 of the embodiment of the present invention, the second magnetic flux may be an actual magnetic flux detected by the terminal device, and the second magnetic flux may also be a second difference value between the actual magnetic flux detected by the terminal device and a preset reference magnetic flux.

In step S111 of the embodiment of the present invention, when the second magnetic flux is an actual magnetic flux detected by the terminal device, the second magnetic flux is an actual magnetic flux detected by the terminal device in a charging state, and if the actual magnetic flux is within a second reference range, it is determined that the data line passes the load current verification. And when the second magnetic flux is a second difference value between the actual magnetic flux detected by the terminal equipment and a preset reference magnetic flux, the second magnetic flux is a difference value between the actual magnetic flux of the terminal equipment in a charging state detected by the terminal equipment and a calibration magnetic flux of the preset terminal equipment and the original data line in a connection state, and if the second difference value is within a second reference range, the data line is determined to pass load current verification. If the data line is confirmed to pass the load current verification, the data line can be further judged to be the original data line.

In step S112 of the embodiment of the present invention, when the second magnetic flux is the actual magnetic flux detected by the terminal device, the second magnetic flux is the actual magnetic flux detected by the terminal device in the charging state, and if the actual magnetic flux exceeds the second reference range, it is determined that the data line fails the load current verification. And when the second magnetic flux is a second difference value between the actual magnetic flux detected by the terminal equipment and a preset reference magnetic flux, the second magnetic flux is a difference value between the actual magnetic flux of the terminal equipment in a charging state detected by the terminal equipment and a calibration magnetic flux of the preset terminal equipment and the original data line in a connection state, and if the second difference value exceeds a second reference range, the data line is determined not to pass the load current verification.

In this case, a prompt message may be generated to prompt the user that the data line is a non-original data line and needs to be replaced.

Specifically, taking the second magnetic flux as an actual magnetic flux detected by the terminal device as an example, the fact that the second magnetic flux exceeds the second reference range means that the second magnetic flux is greater than a maximum value of the second reference range or less than a minimum value of the second reference range; that the second magnetic flux is within the second reference range means that the second magnetic flux is less than or equal to the maximum value of the second reference range and greater than or equal to the minimum value of the second reference range

In the embodiment of the present invention, the second reference range is obtained by calibration using an original data line and is preset in the terminal device before the terminal device leaves a factory.
