Based on the foregoing problems, embodiments of the present application provide a first positioning control method, a computer-readable storage medium, and a terminal, which can improve efficiency of positioning control of the terminal. 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 of a positioning control method according to an embodiment of the present disclosure. The positioning control method may be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palmtop computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers. The specific flow of the positioning control method can be as follows:
101. when the positioning function is detected to be started, a first temperature value of the terminal is obtained.
In this embodiment, the detection of starting the positioning function may be triggered by detecting whether a positioning start instruction is received, and the positioning start instruction may be triggered in various ways, for example, the positioning start instruction may be triggered by a user executing a corresponding operation for the terminal, entering a terminal system setting interface, and turning on a GPS switch to trigger the positioning function. Further, after the terminal receives the positioning starting instruction, the positioning function is started and the positioning function is judged to be started.
Specifically, after the positioning function is detected to be started, a first temperature value can be obtained, and the first temperature value can be a temperature value of the terminal. The temperature value of the terminal may include various values, for example, the temperature of the terminal may be the temperature of the central processing unit, the temperature of the battery, the temperature of the body, or the like.
The first temperature value can be obtained according to a temperature sensor inside the terminal, for example, the first temperature can be the temperature of the central processing unit, and the first temperature value can be determined according to the temperature value detected by the temperature sensor included in the position of the central processing unit. For example, if the temperature value read by the temperature sensor may be 20 ℃ (celsius), the temperature value that can be obtained to the terminal is 20 ℃.
102. And acquiring a voltage value and a resistance value of the positioning antenna, and determining a second temperature value of the positioning antenna according to the voltage value and the resistance value.
Specifically, the second temperature value may be obtained by obtaining a voltage value and a resistance value of the positioning antenna, processing the voltage value and the resistance value according to a preset rule to obtain a processing result, and processing again based on the processing result to obtain the second temperature value. Wherein, the second temperature value can be the temperature of the GPS.
In some embodiments, the step of "obtaining a voltage value and a resistance value of a positioning antenna, and determining a second temperature value of the positioning antenna according to the voltage value and the resistance value" may include the following steps:
acquiring a first voltage value of the second interface through a first voltage detector;
acquiring a second voltage value of the third interface through a second voltage detector;
acquiring a first resistance value of the first resistor, a second resistance value of the second resistor and a third resistance value of the third resistor;
obtaining a power supply voltage value based on the first resistance value, the second resistance value and the first voltage value;
obtaining a fourth resistance value according to the power supply voltage value, the second voltage value and the third resistance value, wherein the fourth resistance value is the resistance value of the thermistor;
and determining a second temperature value corresponding to the fourth resistor based on a relational correspondence library.
Specifically, the first voltage value of the second interface and the second voltage value of the third interface may be obtained through an ADC (Analog-to-digital converter).
Among them, an ADC is a class of devices for converting a continuous signal in analog form into a discrete signal in digital form. An analog to digital converter may provide the signal for measurement. The opposite device becomes a digital-to-analog converter.
For example, the second interface may be electrically connected to the ADC1, the third interface may be electrically connected to the ADC2, the first voltage value may be obtained through the ADC1, and the second voltage value may be obtained through the ADC 2.
Further, a first resistance value of the first resistor, a second resistance value of the second resistor, and a third resistance value of the third resistor are obtained. The first resistor, the second resistor and the third resistor may be resistors with fixed resistance values, and when the circuit is electrically connected, the first resistance value, the second resistance value and the third resistance value may be stored in the terminal circuit storage module, and the circuit storage module may include information of the terminal circuit component.
Specifically, after the first voltage value U1, the second voltage value U2, the first resistance value R1, the second resistance value R2, and the third resistance value R3 are acquired, the processing may be performed on U1, U2, R1, R2, and R3 based on a preset rule. The power supply voltage value Udd is obtained based on the first resistance value R1, the second resistance value R2 and the first voltage value U1, and the first preset calculation formula can be used for processing R1, R2 and U1.
The first preset calculation formula may be: u1 ═ R2 × Udd/(R1+ R2). For example, R1 may be 1 Ω (ohm), R2 may be 1 Ω (ohm), and U1 may be 5V (volt), based on the first preset calculation formula, it may be found that Udd is 2.5V, and then it may be determined that the power supply voltage is 2.5V.
Specifically, a fourth resistance value R4 is obtained according to the power voltage value Udd, the second voltage value U2 and the third resistance value R3, the fourth resistance value may be a resistance value of the thermistor, and the fourth resistance value may be variable. Wherein Udd, R2 and R3 can be processed by a second preset calculation formula. Wherein, the second preset calculation formula may be: u2 ═ R4 × Udd/(R3+ R4). For example, Udd may be 2.5V, R2 may be 1 Ω, R3 may be 1 Ω, U2 may be 5V according to the above step, and R4 may be 1 Ω.
Specifically, after the fourth resistance value is obtained, the second temperature value may be obtained according to a preset rule, where the relationship correspondence library may be a resistance value and temperature correspondence relation table, and may be obtained through an experimental test. For example, the resistance-temperature correspondence may be: 1 omega-10 ℃, 2 omega-20 ℃ and the like. According to the above steps, if R4 is 1 Ω, the GPS temperature can be determined to be 10 ℃.
103. A temperature difference value is determined based on the first temperature value and the second temperature value.
Specifically, the temperature difference is determined, and the first temperature value and the second temperature value may be subjected to operation processing to obtain the temperature difference. For example, the first temperature value may be subtracted from the second temperature value to obtain a temperature difference, and the first temperature value may be 20 ℃, the second temperature value may be 10 ℃, and then the temperature difference may be 10 ℃.
Specifically, the temperature difference value is compared with a preset threshold value, wherein the preset threshold value can be the maximum difference value between the terminal temperature and the GPS temperature, and can be obtained through actual experimental data, and when the temperature difference value is smaller than the preset threshold value, the heating of the GPS is normal, and the power consumption of the terminal cannot be increased.
For example, the temperature difference may be 5 ℃, 10 ℃, or 15 ℃ or the like, and the preset threshold may be 10 ℃ or the like. If the temperature difference is 5 ℃ and the temperature difference is smaller than the preset threshold, the terminal can start the positioning function, namely the GPS can continue to acquire the positioning information; if the temperature difference is 15 ℃ and is greater than the predetermined threshold, step 105 may be executed.
104. And if the temperature difference is greater than the preset threshold value, closing the positioning function.
Specifically, when the temperature difference is greater than the preset threshold, that is, it indicates that the GPS is abnormal in heating, power consumption of the terminal is increased, and the positioning function may be turned off.
In some embodiments, before the step of turning off the positioning function, the following steps are further included:
acquiring a currently opened application program;
judging whether the application program is a preset application program or not, wherein the preset application program preferentially uses the positioning function;
if not, executing the step of closing the positioning function.
Specifically, the currently started application program is acquired, and the currently running application program can be acquired through a background process. For example, the running applications acquired according to the background process may include application a, application B, application C, and the like.
After determining the currently running application, determining whether the application is a preset application, where the preset application may be an application that preferentially uses the positioning function. Specifically, the preset application program may acquire the positioning information in real time for the user to complete the corresponding positioning event.
For example, the preset application program may be navigation software 1, and when the user starts the navigation software, the user may determine a navigation route according to the positioning information acquired by the navigation software 1, and may reach a destination according to the navigation route. Therefore, the preset application program needs to start a positioning function, so as to acquire positioning information to help the user complete related positioning or navigation, and the like.
Specifically, the preset application may be set by the user, for example, the preset application may be navigation software 1, application software 2, application software 3, or the like.
For example, if the obtained currently running application program may be the application software 4, and the application software 4 does not belong to the preset application program, it may be determined that the currently running application program does not include the preset application program, and the positioning function may be turned off.
After the positioning function is turned off, the temperature of the GPS can be detected, whether the temperature of the GPS is reduced to a preset temperature or not is judged, and if yes, the GPS function can be continuously turned on for use. In some embodiments, turning off the positioning function in the step "may further include the steps of:
acquiring temperature values of the positioning antenna every other preset time period;
comparing the temperature value with a target temperature value to obtain a comparison result;
and if the temperature value is smaller than the target temperature value, triggering an opening instruction, and opening a positioning function according to the opening instruction.
After the positioning function is turned off, the temperature of the GPS may be acquired again after a preset time period. For example, the preset time period may be 1 minute, and the temperature of the GPS may be detected again after turning off the GPS function for one minute. And comparing the acquired temperature of the GPS with a target temperature value, and executing the starting or closing operation of the GPS function according to the comparison result. For example, the temperature of the acquired GPS may be 10 ℃, the target temperature value may be 15 ℃, it may be determined that the temperature of the GPS is less than the target temperature value, at this time, the temperature of the GPS has dropped to a normal temperature, and the terminal may start the GPS function again according to a user demand.
In some embodiments, before the step "trigger the open command", the following process may be further included:
detecting whether a user starts an application program, wherein the application program is associated with the positioning function;
if yes, executing the step of starting the opening instruction.
Specifically, whether the user starts the application program is detected, and the user can use the application program to acquire the positioning message. If the user is detected to start the application program, a start instruction can be triggered, and the positioning function is started according to the start instruction.
According to the scheme, when the positioning function is detected to be started, a first temperature value of the terminal is obtained; acquiring a voltage value and a resistance value of a positioning antenna, and determining a second temperature value of the positioning antenna according to the voltage value and the resistance value; determining a temperature difference value based on the first temperature value and the second temperature value; and if the temperature difference is greater than a preset threshold value, closing the positioning function. According to the embodiment, when the terminal is detected to start the positioning function, the terminal temperature value and the GPS temperature value are obtained, the temperature difference value is determined, whether the temperature difference value exceeds the range or not is judged, the switch of the terminal GPS function is controlled according to the judgment result, the heating condition of the GPS is detected in real time, the power consumption of the terminal can be effectively reduced, and therefore the using efficiency of the energy of the mobile terminal is improved.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a second positioning control method according to an embodiment of the present disclosure. In this embodiment, the specific application scenarios of the positioning control method may be as follows:
201. and the terminal detects a positioning instruction triggered by a user and starts a positioning function according to the positioning instruction.
Specifically, the terminal detects a positioning instruction triggered by a user, the user can open the terminal, enter a GPS setting interface, and trigger the positioning instruction by clicking a switch control button of the GPS interface, and when the terminal detects a click operation executed by the user on the current GPS interface, the positioning function can be started.
202. And the terminal acquires the voltage and the resistance value of the GPS interface.
Specifically, the GPS interface may include a plurality of pins, for example, the pins of the GPS interface may include a pin LDO (Low Dropout Regulator), a pin G-1, a pin G-2, a pin GND (Ground), and so on.
The LDO can be connected with VDD (power voltage), GND can be connected with D (ground), a resistor R1 can be connected between the LDO and G-1, a resistor R2 can be connected between G-1 and GND, a resistor R3 can be connected between the LDO and G-2, and a resistor RT can be connected between G-2 and GND; wherein R1, R2, R3 can be resistors with fixed resistance values, RT can be thermistors, and the resistance values of the thermistors change along with temperature.
In this embodiment, the terminal can obtain the voltage values of the pin G-1 and the pin G-2, for example, the voltage of the pin G-1 can be represented as U1, and the voltage of the pin G-2 can be represented as U2; further, resistance values of the resistor 1, the resistor 2 and the resistor 3 are obtained, for example, the resistance value of the resistor 1 may be represented as R1, the resistance value of the resistor 2 may be represented as R2, and the resistance value of the resistor 3 may be represented as R3.
203. And the terminal processes the voltage and the resistance value according to a preset rule to obtain a first temperature value, wherein the first temperature value is the GPS temperature.
Specifically, after the U1, U2, R1, R2 and R3 are acquired, the U1, U2, R1, R2 and R3 may be processed according to a preset rule. The preset rule may include a plurality of calculation formulas, for example, the preset rule may include formula 1: u1 — R2 × Vdd/(R1+ R2), formula 2: u2 RT × Vdd/(R3+ RT). The terminal can obtain the resistance RT of the thermistor according to the calculation formula 1 and the calculation formula 2. For a specific calculation manner, reference may be made to the above embodiments, which are not described herein in detail. For example, the terminal may obtain the resistance value R4 by processing U1, U2, R1, R2, and R3 according to a preset rule, and then obtain a first temperature value according to the resistance value R4, which may be 20 ℃.
204. And the terminal acquires a second temperature value, wherein the second temperature value is the terminal temperature.
Specifically, the second temperature value is obtained, and the second temperature value may be a temperature value of the terminal. The temperature value of the terminal may include various values, for example, the temperature of the terminal may be the temperature of the central processing unit, the temperature of the battery, the temperature of the body, or the like. For example, the terminal temperature may be a body temperature, and the terminal may detect that the current terminal body temperature is 25 ℃ according to the temperature sensor, and then the terminal temperature is 25 ℃.
205. And the terminal determines the temperature difference value between the first temperature value and the second temperature value, compares the temperature difference value with a preset difference value and judges whether the temperature difference value is smaller than the preset difference value.
After the terminal obtains the first temperature and the second temperature, a temperature difference may be obtained according to the first temperature and the second temperature, for example, the first temperature value may be 20 ℃, the second temperature value may be 25 ℃, the preset difference may be 4 ℃, 6 ℃ or the like, the temperature difference may be 5 ℃, and when the preset difference is 4 ℃, the temperature difference is greater than the preset difference, step 207 may be executed; when the preset difference is 6 ℃, the temperature difference is smaller than the preset difference, and step 206 may be performed.
206. The terminal continues to perform the positioning function.
Specifically, the temperature difference value is smaller than the preset difference value, which can indicate that the temperature value of the GPS is in the normal heating range at the time, and the positioning function of the GPS can be continuously used without affecting the use of the GPS by continuously using the positioning function of the GPS.
207. The terminal stops performing the positioning function.
Specifically, the temperature difference is greater than the preset difference, which may indicate that the temperature value of the GPS is in an abnormal heating range at this time, that is, the current temperature of the GPS affects the use of the GPS. The terminal can close the positioning function, but if the application program started by the current user continues to acquire the current position information through the GPS positioning function. Then, the terminal may detect whether the current user starts the related software, where the related software may be navigation software, and the like, and the user needs to obtain the positioning information in real time.
For example, when the terminal detects that the background application program does not have navigation software, the positioning function of the GPS can be turned off, so that the function consumption of the terminal is reduced.
According to the scheme, when the positioning function is detected to be started, a first temperature value of the terminal is obtained; acquiring a voltage value and a resistance value of a positioning antenna, and determining a second temperature value of the positioning antenna according to the voltage value and the resistance value; determining a temperature difference value based on the first temperature value and the second temperature value; and if the temperature difference is greater than a preset threshold value, closing the positioning function. According to the embodiment, when the terminal is detected to start the positioning function, the terminal temperature value and the GPS temperature value are obtained, the temperature difference value is determined, whether the temperature difference value exceeds the range or not is judged, the switch of the terminal GPS function is controlled according to the judgment result, the heating condition of the GPS is detected in real time, the power consumption of the terminal can be effectively reduced, and therefore the using efficiency of the energy of the mobile terminal is improved.
