Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a flowchart illustrating a method for controlling a charging indicator lamp of a mobile terminal according to a preferred embodiment of the present invention. The control method of the mobile terminal charging indicator lamp comprises the following steps:
and S100, acquiring the port voltage of the connection end of the mobile terminal and the intelligent terminal, and judging whether the mobile terminal is connected with the intelligent terminal.
Preferably, the step S100 specifically includes:
s101, acquiring port voltage of a connecting end of the mobile terminal and the intelligent terminal every preset time;
step S102, when the port voltage changes from low level to high level, the mobile terminal is judged to be connected with the intelligent terminal;
and step S103, when the port voltage changes from high level to low level, judging that the mobile terminal is not connected with the intelligent terminal.
During specific implementation, because people often forget to take the charger in the daily use process, the intelligent connection is charged on some intelligent terminals. For example, the mobile terminal is connected to a computer for charging. As shown in fig. 2, fig. 2 is a schematic diagram of a current flow when the mobile terminal of the present invention is connected to an intelligent terminal for charging. After the mobile terminal is connected with the intelligent terminal, one part of current output by the intelligent terminal is supplied to the mobile terminal to maintain the use of the mobile terminal, so that the power consumption of the mobile terminal is met (path A in figure 2), and the other part of current is used for charging a battery of the mobile terminal (path B in figure 2). Namely, it isAnd the former part has higher priority than the latter part, i.e. the current is charged in the battery of the mobile terminal only when the current is left after the use of the mobile terminal is maintained, i.e. the current flows from the intelligent terminal to the battery of the mobile terminal, which represents that the mobile terminal is being charged.
If it is notthere are two cases, the first case isit is stated that the current output by the intelligent terminal can only satisfy the power consumption of the mobile terminal, and no extra current is charged in the battery of the mobile terminal, and the mobile terminal is not charged at this time. The second situation is that the battery is fully charged, the battery of the mobile terminal does not need to be charged, the intelligent terminal only needs to meet the power consumption, and the mobile terminal is not charged at the moment. However, many times, the user may play some large games while charging the mobile terminal with the smart terminal, which is very power-consuming, and most of the smart terminals output currentAll are relatively small, for example, the current output by a computer is only 500mA, so that the current output by the intelligent terminal at the momentnot enough to satisfy the power consumption of the mobile terminal, and the battery is needed to participate in the power supply of the mobile terminal, then. As shown in fig. 3, fig. 3 is a second schematic diagram of a current flow direction when the mobile terminal of the present invention is connected to a smart terminal for charging. At this timeas shown by the current direction of the B-path in fig. 3, current is a power consumption from the battery to the mobile terminal, and thus the mobile terminal is not being charged at this time, as opposed to the current direction of the B-path in fig. 2.
Therefore, in order to better judge whether the battery of the mobile terminal is being charged, the present invention sets the direction of current flowing from the intelligent terminal into the battery of the mobile terminal to be a first direction (i.e., the B-path current direction in fig. 2), and when current flows into the battery of the mobile terminal in the first direction, it represents that the mobile terminal is currently being charged. Therefore, the real charging condition of the mobile terminal is judged more accurately.
In specific implementation, the mobile terminal acquires the port voltage of the connection end of the mobile terminal and the intelligent terminal every preset time. That is, a time interval is preset, for example, every half hour, for periodically detecting the port voltage of the intelligent terminal connected with the mobile terminal. When detecting that the port voltage is changed from a low level to a high level, judging that the mobile terminal is connected with the intelligent terminal; and when the port voltage is changed from high level to low level, judging that the mobile terminal is not connected with the intelligent terminal. For example, the output voltage of the computer is 6V, when the mobile terminal is not connected to the computer and the port voltage of the connection end of the mobile terminal and the computer is 0V, when it is detected that the port voltage of the connection end of the mobile terminal and the computer changes from 0V to 6V, it indicates that the mobile terminal and the intelligent terminal are connected at this time. When the voltage of the port of the connection end of the mobile terminal and the computer is detected to be changed from 6V to 0V, the connection end indicates that the mobile terminal and the intelligent terminal are disconnected. By detecting the port voltage change of the connecting end of the mobile terminal and the intelligent terminal, whether the mobile terminal is connected with the intelligent terminal or not can be judged more accurately, and convenience is brought to a user.
and S200, when the mobile terminal is connected with the intelligent terminal, acquiring the voltage of two ends of a resistor preset at the cathode end of the battery of the mobile terminal, and judging the current direction of current flowing through the battery of the mobile terminal.
Preferably, the step S200 specifically includes:
step S201, when the mobile terminal is judged to be connected with the intelligent terminal, acquiring a first voltage and a second voltage at two ends of a resistor preset at the negative electrode end of a battery of the mobile terminal;
and step S202, judging the current direction of the current flowing through the mobile terminal battery through the acquired first voltage and second voltage.
In order to better judge the flow direction of the current flowing through the mobile terminal battery during specific implementation, the invention is characterized in that a resistor is connected in series with the negative end of the mobile terminal battery in advance and is used for judging the current direction of the current flowing through the mobile terminal battery. When the mobile terminal detects that the mobile terminal is connected with the intelligent terminal, a first voltage and a second voltage at two ends of a resistor preset at the negative electrode end of a battery of the mobile terminal are obtained. The first voltage is a voltage close to the negative end of the mobile terminal battery; the second voltage is a voltage far away from the negative end of the mobile terminal battery. And judging the flow direction of the current flowing through the mobile terminal battery according to the acquired first voltage and the acquired second voltage.
and step S300, when the current direction is the same as the preset first direction, controlling a charging indicator lamp on the mobile terminal to be turned on.
preferably, the step S300 specifically includes:
Step S301, when the first voltage is greater than the second voltage, representing that current flows into the mobile terminal battery from the intelligent terminal, and the current is the same as a preset first direction;
and step S302, controlling a charging indicator lamp of the mobile terminal to be on to remind a user that the mobile terminal is currently being charged.
In specific implementation, when the acquired first voltage is greater than the second voltage, it is indicated that current flows into the mobile terminal battery from the intelligent terminal at the moment, and the current is the same as the current in the preset direction, it is indicated that the mobile terminal is charging at the moment, so that the charging indicator lamp of the mobile terminal is controlled to be turned on to prompt the user that the mobile terminal is charging currently. Preferably, if the first voltage is less than the second voltage, it indicates that the current flows from the battery of the mobile terminal, and the current is different from the preset first direction, it indicates that the mobile terminal is not being charged, and therefore the charging indicator lamp of the mobile terminal is controlled to be turned off. Therefore, the user can better and intuitively know the real charging condition of the mobile terminal, and convenience is provided for the user.
