Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
Based on the above problems, embodiments of the present application provide a first SIM card detection method, apparatus, storage medium, and terminal, which can effectively improve the detection efficiency of a terminal SIM card. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a SIM card detection method according to an embodiment of the present disclosure. The SIM card detection method may be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palm computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers.
The terminal can comprise a magnetic sensor for detecting the intensity of magnetic field and a distance sensor for detecting distance, and the magnetic sensor and the distance sensor can be arranged in multiple areas inside the terminal, for example, can be arranged at a terminal SIM card seat. The specific process of the SIM card detection method of the terminal may be as follows:
101. when the magnetic field intensity detected by the magnetic sensor changes, the difference value between the current magnetic field intensity value and the previous historical magnetic field intensity value is obtained.
In this embodiment, the magnetic sensor may be disposed inside the terminal, for example, the magnetic sensor may be disposed at a position near the end of the SIM card holder, and the SIM card holder may be made of a metal material. Specifically, the magnetic sensor is started to work to detect the change of the magnetic field intensity through the magnetic sensor, and the change of the magnetic field intensity in the SIM card seat area is detected. Because the magnetic sensor is arranged near the position of the SIM card installed on the SIM card seat, and one surface of the SIM card is generally made of metal material, the magnetic field can be changed by the slave, when a user replaces the SIM card, the magnetic sensor is inevitably caused to detect the magnetic field intensity change of the position of the SIM card, and thus whether the SIM card is inserted or not can be detected timely and conveniently.
Specifically, the magnetic sensor is a device that converts a change in the magnetic property of the sensor due to an external factor such as a magnetic field, a current, a stress strain, a temperature, or light into an electric signal, and detects a corresponding physical quantity in this manner.
The current magnetic field strength value may be acquired when the magnetic sensor detects that the current magnetic field strength has changed, for example, the current magnetic field strength value may be 300 μ T (magnetic field strength unit: microtlas). After the current magnetic field strength value is obtained, the current magnetic field strength value may be compared with the last detected historical magnetic field strength value, and a difference between the current magnetic field strength value and the last historical magnetic field strength value may be obtained.
The historical magnetic field strength value can be used for triggering the magnetic sensor to detect the magnetic strength change value of the SIM card seat area at preset time intervals, and the historical magnetic field strength value can be stored in the memory. After the change of the magnetic field strength value is detected, the current magnetic field strength value and the last detected magnetic field strength value can be processed to obtain the difference value between the current magnetic field strength value and the last magnetic field strength value.
For example, the current magnetic field strength value may be 300 μ T, and the previous historical magnetic field strength value obtained from the memory may be 200 μ T, and the difference between the current magnetic field strength value and the previous historical magnetic field strength value may be 100 μ T.
In some embodiments, in addition to triggering the magnetic sensor to detect the current magnetic field strength at preset time intervals, there may be a plurality of ways to trigger the magnetic field strength to detect the current magnetic field strength value, for example, when detecting that the position of the SIM card holder changes, the magnetic sensor is triggered to start detecting the current magnetic field strength value. Wherein, the SIM card seat can be detachable, and the SIM card detecting method can further include the following steps:
when the distance sensor detects that the distance between the magnetic sensor and the SIM card holder changes, the magnetic sensor is triggered to detect the magnetic field intensity of the SIM card holder.
Specifically, the position of detecting the SIM card holder can be through distance sensor, and this distance sensor can be set up in each position inside the terminal, and this place is mainly to the detection of the position of the SIM card holder, so the preferred can set up near the SIM card holder region, can more accurate detect the position change of the SIM card holder.
A distance sensor, also called a displacement sensor, is a sensor for sensing a distance between the sensor and an object to perform a predetermined function, and the distance sensor may be classified into an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, and the like according to its operating principle. At present, most of distance sensors used on mobile phones are infrared distance sensors, the working principles of other types of distance sensors are different, the distance of the distance sensors is judged by transmitting and receiving certain substances, and the transmitted substances can be ultrasonic waves, light pulses and the like.
For example, a user may pull out/insert the SIM card socket, and at this time, the distance sensor may detect that the position of the SIM card socket changes, and then may trigger the magnetic sensor to start detecting the magnetic field strength of the SIM card socket area.
102. The difference is compared with a preset difference.
Specifically, the difference value is compared with a preset difference value, the preset difference value can be obtained through a plurality of experiments in advance, the experiment can be that when the SIM card seat is put in or not put in, the magnetic field strength value detected by the magnetic sensor is set to the preset difference value by acquiring the magnetic field strength value after the SIM card seat is put in the terminal for a plurality of times and the magnetic field strength value after the SIM card seat is taken out from the terminal for a plurality of times, and the current state of the SIM card seat can be judged by comparing the difference value with the preset difference value. For example, the preset difference may be 50 μ T.
103. And when the difference value is larger than the preset difference value, sending a communication signal to the SIM card.
Specifically, after comparing the difference between the current magnetic field strength value and the previous historical magnetic field strength value with the preset difference, a comparison result can be obtained, and then corresponding operation is executed according to the comparison result.
When the difference is greater than the preset difference, it can be determined that the SIM card holder is in the terminal internal state, and then a communication signal can be sent to the SIM card. Specifically, sending a communication signal to the SIM card may mean sending a reset signal to the SIM card, where the reset signal refers to sending the reset signal to a hardware-specific interface by a manual or automatic method to restore the operation of software to a specific program segment, and this process is a reset process; in the process, a signal sent to a hardware specific interface by a manual or automatic method is a reset signal.
In some embodiments, when comparing the difference between the current magnetic field strength value and the previous historical magnetic field strength value with the preset difference, the comparison result may further include a plurality of kinds, that is, the following steps may further be included:
and if the difference is less than or equal to the preset difference, detecting that the SIM card does not exist, and prompting the user that the SIM card does not exist.
Specifically, when the difference is less than or equal to the preset difference, it may be determined that the SIM card holder is in a non-terminal internal state, and it may be detected that the SIM card does not exist in the current SIM card holder, and a prompt message may be displayed on the display interface, for example, the prompt message may include contents such as "SIM card not detected, please insert SIM card", and so on, to prompt the user, and the current terminal does not detect the SIM card.
104. And determining the state of the SIM card according to the communication result.
Specifically, after the communication signal is sent to the SIM card, the state of the SIM card can be determined according to the communication result, so that the SIM card can be accurately detected.
In some embodiments, the step of "determining the state of the SIM card according to the communication result" may include the following steps:
and when the communication result is that a response message of the SIM card for the communication signal is received, judging that the SIM card is in a working state.
And when the communication result is that the response message of the SIM card to the communication signal is not received, judging that the SIM card is in a non-working state.
Specifically, after sending the communication signal to the SIM card, if a response message of the SIM card to the communication signal is received, it may be determined that the SIM card is in a working state, and may normally perform other functions such as communication; or after the communication signal is sent to the SIM card, if the response message of the SIM card to the communication signal is not received, the SIM card can be determined to be in a non-working state, i.e. it can be indicated that the SIM card has a fault problem, and the user can be prompted in time, so as to facilitate replacement of the SIM card.
For example, the sending of the communication signal to the SIM card may be sending a command to the SIM card to read a corresponding register value, and if the corresponding register value of the SIM card is successfully read, the SIM card may be in an operating state, and if the corresponding register value of the SIM card is read, the SIM card may be in a non-operating state.
In some embodiments, after detecting that the SIM card is in the inactive state, various operations may be performed, for example, after the step "determining that the SIM card is in the inactive state", the following steps may be further included:
and displaying a prompt message on the current display interface, wherein the prompt message is used for prompting the user that the SIM card works abnormally.
Specifically, after the SIM card is detected to be in the non-working state, a prompt message may be displayed on the current display interface, where the prompt message may be used to prompt other information such as abnormal working of the SIM card, for example, the prompt message may be content such as "abnormal current SIM card occurs, please confirm by pulling the SIM card", and may be used to prompt the user, and the current terminal detects the abnormal working of the SIM card.
The embodiment of the application discloses an SIM card detection method, which comprises the following steps: when the magnetic field intensity detected by the magnetic sensor changes, acquiring a difference value between a current magnetic field intensity value and a previous historical magnetic field intensity value; comparing the difference value with a preset difference value; when the difference value is larger than the preset difference value, sending a communication signal to the SIM card; and determining the state of the SIM card according to the communication result. According to the embodiment of the application, the magnetic sensor is arranged at the SIM card seat of the terminal, the magnetic field intensity of the SIM card seat is detected, the state of the SIM card is detected according to the magnetic field intensity value, and the detection efficiency of the SIM card of the terminal can be effectively improved.
Referring to fig. 2, fig. 2 is a schematic flowchart of a second SIM card detection method according to an embodiment of the present application. The specific scene application of the SIM card detection method can be as follows:
201. and the terminal detects the magnetic field strength value at the SIM card seat every a preset time period.
In this embodiment, when the terminal is in the power-on state, the terminal may supply power to the magnetic sensor, detect the magnetic field strength at the SIM card holder by the magnetic sensor every preset time period, obtain a detected magnetic field strength value, and store the magnetic field strength value in the memory. The magnetic sensor can be arranged at the SIM card seat, and can detect the magnetic field strength value at the SIM card seat more accurately.
For example, the magnetic field strength value acquired by the terminal may be 200 μ T, 300 μ T, 400 μ T, or the like.
202. And the terminal acquires the difference value between the current magnetic field strength value and the previous historical magnetic field strength value.
Specifically, after obtaining the current magnetic field strength value, the terminal may compare the current magnetic field strength value with a previous historical magnetic field strength value, where the previous historical magnetic field strength value may be obtained from the memory.
After determining the current magnetic field strength value and the previous historical magnetic field strength value, a difference between the current magnetic field strength value and the previous historical magnetic field strength value may be obtained. For example, the current magnetic field strength value may be 200 μ T, the previous historical magnetic field strength value may be 100 μ T, and the difference between the current magnetic field strength value and the previous historical magnetic field strength value may be 100 μ T.
203. And the terminal judges whether the difference value between the current magnetic field strength value and the previous historical magnetic field strength value is larger than a preset difference value.
Specifically, after the difference between the current magnetic field strength value and the previous historical magnetic field strength value is obtained, the difference may be compared with a preset difference, and whether the difference is greater than the preset difference is determined.
For example, the difference between the current magnetic field strength value and the previous historical magnetic field strength value may be 100 μ T, the preset difference may be 50 μ T, 100 μ T, or the like, and if the preset difference is 50 μ T, it may indicate that the difference between the current magnetic field strength value and the previous historical magnetic field strength value is greater than the preset difference, step 205 may be performed; if the predetermined difference is 100 μ T, it may indicate that the difference between the current magnetic field strength value and the previous historical magnetic field strength value is equal to the predetermined difference, and step 203 may be executed.
204. And the terminal displays the prompt message on the current display interface.
Specifically, after the difference value is determined according to the current magnetic field strength value and the previous historical magnetic field strength value, when the difference value between the current magnetic field strength value and the previous historical magnetic field strength value is smaller than or equal to a preset difference value, it can be determined that the SIM card does not exist in the current terminal, because the variation range of the magnetic field strength at the SIM card seat is within the preset variation range, it can be indicated that the SIM card is placed in the SIM card seat, at this time, a prompt message can be displayed on the current display interface, the user can be reminded that the SIM card does not exist in the current terminal, and the user can perform other operations and the like.
For example, the display content of the current display interface may be "to detect the SIM card, please insert the SIM card", or other content.
205. And the terminal sends a communication signal to the SIM card.
Specifically, if it is detected that the difference between the current magnetic field strength value and the previous historical magnetic field strength value is greater than the preset difference, it may be determined that the SIM card exists in the current terminal, and the terminal sends a communication signal to the SIM card, where the definition of the communication signal may be found in the foregoing embodiment, and details are not repeated in this step.
206. And the terminal determines the state of the SIM card according to the communication result with the SIM card.
Specifically, after sending the communication signal to the SIM card, the terminal may determine the state of the SIM card according to a response of the SIM card to the communication signal.
For example, after sending the communication result To the SIM card, the terminal may obtain an ATR (Answer To Reset) of the SIM card, where the ATR is an instruction based on ISO7816 (a contact card reading protocol) specification, and when the SIM card interacts with the mobile terminal, and the SIM card receives the Reset signal, the terminal sends an ATR To the mobile phone, which indicates that the SIM card starts To respond, and this is a function of the SIM card; if the acquisition is successful, the SIM card is in place, otherwise, the SIM card is not in place.
The ISO7816 standard is a standard half-duplex interface, the module is used as a master device to control the operation of the SIM card, and the SIM card is used as a slave device to generate response signals only under two conditions: firstly, after receiving RST signal, sending ATR, and secondly: and responding after receiving the command. Therefore, the SIM card driver module, as a master device, mainly performs two operations: the RST is sent waiting for the ATR, the command is sent and the SIM card is waited for an answer.
The initial communication between the ATR (answer to reset) SIM module and the SIM card requires the exchange of some protocol data, which is done by the ATR protocol specified in ISO 7816. The ATR protocol is implemented by the SIM module controlling the SIM _ rst signal.
The SIM card may return an acknowledgement signal during the time when SIM _ rst is low or during the time when SIM _ rst is high. If the ATR answer signal of the SIM card is still not received after SIM _ rst keeps high level 40000 SIM _ clk cycles, the SIM is not existed or the transmission channel is in problem.
The first character of the ATR answer signal returned by the SIM card indicates whether the SIM card supports direct mode or reverse mode transmission, and this character is defined as the initial character. If 11011100 is returned by the SIM, it indicates that the SIM card supports direct mode; if the SIM card returns 11000000, the reverse mode is supported by the SIM card.
By definition, a reset acknowledgement is the value of a series of bytes that are sent by the card to the interface device as a response to a reset command. On the I/O circuit, each byte is transmitted in an asynchronous character.
The embodiment of the application discloses an SIM card detection method, which comprises the following steps: when the magnetic field intensity detected by the magnetic sensor changes, acquiring a difference value between a current magnetic field intensity value and a previous historical magnetic field intensity value; comparing the difference value with a preset difference value; when the difference value is larger than the preset difference value, sending a communication signal to the SIM card; and determining the state of the SIM card according to the communication result. According to the embodiment of the application, the magnetic sensor is arranged at the SIM card seat of the terminal, the magnetic field intensity of the SIM card seat is detected, the state of the SIM card is detected according to the magnetic field intensity value, and the detection efficiency of the SIM card of the terminal can be effectively improved.
