Description

Device, method, storage medium and mobile terminal for detecting SIM card

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a device, a method, a storage medium, and a mobile terminal for detecting a SIM card.

Background

Currently, in order to communicate with the outside, a Subscriber Identity Module (SIM) is usually used in a mobile terminal to adapt to functions such as internet access and telephone. The SIM card is placed in the mobile terminal through the card holder. That is to say, the SIM card is placed at the designated position of the card holder, and the user inserts the card holder into the card slot of the mobile terminal card holder, so that the corresponding contact in the card slot is connected with the corresponding contact of the SIM card, thereby enabling the SIM card to be in an available activation state. In practical use, the SIM card needs to be closely placed in the relevant position of the card slot of the mobile terminal card holder. Because the space that the card slot belongs to is airtight, and the volume of the SIM card is smaller, therefore, the situation such as skew may take place between the contact of the SIM card and the corresponding contact in the card slot in the process of falling, striking. In addition, when the mobile terminal reads and writes large-scale data, the operation of the SIM card is very quick. The above situation may cause the SIM card to locally heat up, if the situation is light, the data operation of the SIM card is disabled, and if the situation is heavy, the SIM card is damaged. In addition, although the size of the card holder is small, the material of the card holder is very exquisite. The material of the card holder is often protected in the form of a trade secret for all large manufacturers. When the card support which is not self-provided by the mobile terminal is used, the SIM card can generate heat further and the heat dissipation is not good because the material of the card support is not selected properly.

In view of the above, how to effectively detect the condition of the SIM card becomes an important issue for the relevant technicians and researchers.

The embodiment of the application provides a device for detecting an SIM card, which is suitable for a mobile terminal. The mobile terminal includes: a pin connector 110 disposed on a main board of the mobile terminal for connecting the SIM card to the main board, a card holder 120 for carrying the SIM card, and a card socket 130 integrally connected to a housing 140 of the mobile terminal and for fixing the card holder 120. The structures of the pin connector 110, the card holder 120 and the card socket 130 are shown in fig. 1 and fig. 2. Specifically, the pin connector 110 is disposed on a main board of the mobile terminal for connecting the SIM card to the main board. The socket 130 is used for receiving and fixing the card holder 120. The card socket 130 and the housing 140 of the mobile terminal are integrated. The card holder 120 is used for carrying a SIM card. The card holder 120 can be inserted into the card socket 130 and fixed on the card socket 130, and can also be pulled out from the card socket 130 to facilitate the replacement of the SIM card.

Referring to fig. 3, a first resistor R1, a second resistor R2, a third resistor R3 and a thermistor RT are respectively disposed on the card holder 120, and one end of the first resistor R1 is connected to one end of the second resistor R2 to form a first connection contact NCC 1. One end of the third resistor R3 is connected with the other end of the first resistor R1, and forms a power supply contact VCC. The other end of the third resistor R3 is connected to one end of the thermistor RT and forms a second connection contact point NCC 2. The other end of the thermistor RT is connected to the other end of the second resistor R2, and forms a ground contact GND.

Referring to fig. 4, the apparatus includes a power supply module 410, a control module 450, a first detection module 420, a second detection module 430, and a comparison module 440.

The power supply module 410 is connected to the power supply contact VCC, and is configured to provide power to the power supply contact VCC on the card holder 120. In this embodiment, the power supply module 410 may be connected to a power supply contact VCC through the pin connector 110 of the mobile terminal to provide power to the power supply contact VCC. In particular, a VCC voltage may be provided to the supply contact VCC. In some other embodiments, the power supply module 410 may also provide power to the power supply contact VCC in other manners.

The first detecting module 420 is connected to the first connection contact point NCC1 and the second connection contact point NCC2, respectively, and the first detecting module 420 is configured to obtain voltage values of the first connection contact point NCC1 and the second connection contact point NCC2, and calculate a card holder temperature of the card holder 120. Optionally, the first detecting module 420 may further include two analog-to-digital converting modules 421, where the two analog-to-digital converting modules 421 are respectively connected to the first connection contact NCC1 and the second connection contact NCC2, and the two analog-to-digital converting modules are configured to respectively obtain voltage values of the first connection contact NCC1 and the second connection contact NCC2 through analog-to-digital conversion. Of course, in other embodiments, the first detection module 420 may directly obtain the voltages of the first connection contact point NCC1 and the second connection contact point NCC2 in other manners, and the voltages are digital signals.

Further, the calculation of the capto temperature is specifically as follows:

formula 1 is VNCC1 ═ R2 × VCC/(R1+ R2), and formula 2 is VNCC2 ═ RT × VCC/(RT + R3). VNCC1 is the voltage value of the first connection contact point NCC1, VNCC2 is the voltage value of the second connection contact point NCC2, R1 is the resistance value of the first resistor R1, R2 is the resistance value of the second resistor, R3 is the resistance value of the third resistor, and RT is the resistance value of the thermistor. The resistances of the first resistor R1, the second resistor R2 and the third resistor R3 are fixed resistances, and the thermistor RT is an ntc (negative temperature coefficient) type resistor. VCC and RT in equations 1 and 2 are non-constant, and VCC may vary slightly according to the power supplied by the power supply module 410. RT will vary with temperature. Therefore, according to the formula 1 and the formula, the resistance value of the thermistor RT can be calculated and obtained by obtaining only the voltage values of the first connection contact point NCC1 and the second connection contact point NCC2 (i.e., VNCC1 and VNCC2), so as to obtain the card holder temperature of the card holder 120. It should be noted that the first detection module 420 can obtain the voltage values of the contact points corresponding to the first connection contact point NCC1 and the second connection contact point NCC2 (the contact points are disposed on the pin connector 110) through the pin connector 110. Of course, the voltage values of the first connection contact point NCC1 and the second connection contact point NCC2 may be directly obtained.

The second detection module 430 is configured to obtain a reference temperature. The reference temperature may be a temperature of a surface of the mobile terminal, or a temperature corresponding to a weather forecast of the current location obtained through a network. The reference temperature is a reference, and the difference between the temperature of the card holder and the reference temperature is not too large. The reference temperature may be a variable.

The comparing module 440 is configured to calculate a difference between the temperature of the card holder and the reference temperature, and compare the difference with a preset threshold. The control module 450 is configured to perform a corresponding operation on the SIM card according to the comparison result. Specifically, when the comparing module 440 determines that the difference between the card holder temperature and the reference temperature is smaller than the preset threshold, the control module 450 performs normal operations on the SIM card, such as identifying the SIM card, reading data in the SIM card, and regarding the card holder 120 as being in a normal state. When the comparing module 440 determines that the difference between the cradle temperature and the reference temperature is greater than the preset threshold, the control module 450 stops performing any operation on the SIM card, and considers the cradle 120 to be in an abnormal state. Therefore, through the structural design, the problems of SIM card data operation failure or SIM card damage and the like caused by too fast temperature change can be avoided, and the problem that the SIM card is easy to damage when a user uses a self-matched card support or a non-standard card support can be prevented, so that the aim of protecting the SIM card is further fulfilled.

The first detection module 420, the second detection module 430, the comparison module 440 and the control module 450 may be disposed in a processor of the mobile terminal, but are not limited thereto, and may also be disposed in other modules of the mobile terminal.

In this embodiment, the apparatus further includes a timing module 460, the timing module 460 is respectively connected to the first detection module 420, the second detection module 430, the comparison module 440, and the control module 450, and the timing module 460 is configured to start the first detection module 420, the second detection module 430, the comparison module 440, and the control module 450 at a preset time. Specifically, the timing module 460 may start the first detection module 420, the second detection module 430, the comparison module 440, and the control module 450 at a fixed time interval of an equal amount, so as to further improve the reliability of the normal operation of the card holder 120. The timing module 460 may include a timer with a preset fixed time of 5 seconds, if the fixed time is set too short, although the SIM card is detected faster, the power consumption of the mobile terminal will increase, and if the fixed time is set too long, the detection process may become too slow. Generally, the card holder 120 with the SIM card is placed in the card socket 130 and the whole time for the SIM card to complete the registration is about 5 seconds, so the fixed time of the timer can be set to 5 seconds, but is not limited thereto. In some other embodiments, the timing module 460 may also activate the first detection module 420, the second detection module 430, the comparison module 440, and the control module 450 at unequal intervals.

In this embodiment, the apparatus further includes a detection module 470, the detection module 470 is connected to the power supply module 410, and the detection module 470 is configured to send a relevant instruction to the power supply module 410 to provide power to the SIM card when it is detected that the card holder 120 with the SIM card is placed in the card socket 130. The detection module 470 can determine that the card holder 120 with the SIM card is placed in the card socket 130 in the following manner. Specifically, when the card holder 120 with the SIM card is not placed in the card socket 130, the voltage at the power supply contact VCC is at a low level, and when the card holder 120 with the SIM card is placed in the card socket 130, the voltage at the power supply contact VCC is at a high level, so that it is determined that the card holder 120 with the SIM card is placed in the card socket 130 by changing the voltage at the power supply contact VCC from low to high. Of course, in other embodiments, the pin of the pin connector 110 may be changed to identify whether the SIM card is placed in the card holder 120.

Referring to fig. 5, an embodiment of the present application provides a method for detecting a SIM card, which uses the apparatus for detecting a SIM card. The specific structure of the apparatus for detecting a SIM card is as described above, and is not described herein again.

The method comprises the following steps:

step S510: and starting the first detection module, the second detection module, the comparison module and the control module.

In this step, the method further comprises: the first detection module 420, the second detection module 430, the comparison module 440 and the control module 450 are started by the timing module 460 at a preset time timing. This can further improve the reliability of the normal operation of the card holder 120.

Step S520: and acquiring voltage values of the first connecting contact point and the second connecting contact point through the first detection module, and calculating to obtain the card support temperature of the card support.

In this step, the voltage values of the first connection contact point NCC1 and the second connection contact point NCC2 may be acquired by the two analog-to-digital conversion modules through analog-to-digital conversion.

The calculation of the capto temperature is specifically as follows: formula 1 is VNCC1 ═ R2 × VCC/(R1+ R2), and formula 2 is VNCC2 ═ RT × VCC/(RT + R3). VNCC1 is the voltage value of the first connection contact point NCC1, VNCC2 is the voltage value of the second connection contact point NCC2, R1 is the resistance value of the first resistor, R2 is the resistance value of the second resistor, R3 is the resistance value of the third resistor, and RT is the resistance value of the thermistor. The resistances of the first resistor R1, the second resistor R2 and the third resistor R3 are fixed resistances, and the thermistor RT is an ntc (negative temperature coefficient) type resistor. VCC and RT are variable in equations 1 and 2, and VCC may vary slightly according to the power supplied by the power supply module 410. RT will vary with temperature. Therefore, according to the formula 1 and the formula, the resistance value of the thermistor RT can be calculated and obtained by obtaining only the voltage values of the first connection contact point NCC1 and the second connection contact point NCC2 (i.e., VNCC1 and VNCC2), so as to obtain the card holder temperature of the card holder 120.

In step S530, a reference temperature is obtained through the second detection module.

The reference temperature may be a temperature of a surface of the mobile terminal, or a temperature corresponding to a weather forecast of the current location obtained through a network. The reference temperature is a reference, and the difference between the temperature of the card holder and the reference temperature is not too large. The reference temperature may be a variable.

Step S540: and calculating the difference value between the temperature of the card holder and the reference temperature through a comparison module, and comparing the difference value with a preset threshold value.

Step S550: and executing corresponding operation on the SIM card through the control module according to the comparison result.

In this embodiment, before step S510, the method further includes step S501: when the detection module 470 detects that the card holder 120 with the SIM card is placed in the card socket 130, it sends a relevant instruction to the power supply module 410 to supply power to the SIM card.
