Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In the present embodiment, a charging and discharging method of a terminal is provided, and fig. 1 is a flowchart of a charging and discharging method of a terminal according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, detecting whether a wireless signal with a specific frequency meeting the preset signal intensity is received;
step S104, determining the current working mode of the wireless charging and discharging unit according to the wireless signal and a preset identification code, wherein the working mode is a receiving mode or a transmitting mode, and the identification code is used for distinguishing equipment to be charged and wireless charging equipment;
step S106, under the condition that the working mode is the receiving mode, wirelessly charging the self through a charging and discharging coil connected with the receiving unit; and under the condition that the working mode is the transmitting mode, wirelessly supplying power to the equipment to be charged through the charging and discharging coil connected with the transmitting unit.
Through the steps, when the wireless signal of the specific frequency meeting the preset signal strength is received, it can be considered that the equipment capable of being effectively charged or waiting for charging operation exists near the terminal, at the moment, the terminal can determine the working mode of the wireless charging and discharging unit according to the received wireless signal and the agreed identification code in advance, thereby determining whether to wirelessly charge the terminal or wirelessly supply power to the equipment to be charged, so that the terminal has the functions of wireless charging and wireless power supply, the problem that the wireless charging equipment and the wireless power supply equipment in the related technology are single in function and inconvenient for users is solved, the use flexibility of the wireless charging and discharging equipment is improved, and the user experience is improved.
As a preferred embodiment, in order to ensure the reliability of the charging and discharging device of the opposite terminal, before determining the current working mode of the wireless charging and discharging unit, the identity validity of the sender of the wireless signal may be determined; or, whether the sender of the wireless signal is within the effective range is judged. For example, whether the sender is legitimate or not can be determined by the content of the identification code carried in the wireless signal. Through the mode, the possibility that the terminal is in an abnormal condition in the charging and discharging process is reduced, for example, the condition that the terminal sends the limited electric quantity to the incorrect opposite-end device to be charged when power is supplied can be avoided, and therefore resources are saved.
The identification code in step S104 may be set by the user in advance, or may be agreed by other manners, and in specific implementation, one of the charging and discharging ends may send the identification code to the opposite end device in a wireless signal carried by the identification code. For example, the device on the side to be charged may transmit the identification code to the device on the opposite end, or the device on the side to be powered may transmit the identification code. As a preferred embodiment, the device of the active initiator of charging or power supply may also send the identification code, and after receiving the identification code, the terminal may determine, according to the identification code, whether the sender of the wireless signal is the device to be charged or the wireless charging device; under the condition that a sender of the wireless signal is the equipment to be charged, the current working mode of the wireless charging and discharging unit can be determined to be a transmitting mode; in the case that the sender of the wireless signal is the wireless charging device, it may be determined that the current operation mode of the wireless charging and discharging unit is the receiving mode. Through the mode, the terminal can conveniently adjust the working mode of the terminal according to the requirements of charging and discharging the opposite terminal equipment, and the use flexibility of the terminal is improved.
In specific implementation, only one charging and discharging coil can be arranged in the terminal, and the switching of the working mode of the wireless charging and discharging unit between the transmitting mode and the receiving mode is realized by controlling the receiving unit or the transmitting unit at the other end connected with the coil. For example, in the case that the charging and discharging coil is connected to the receiving unit (i.e., the working mode of the charging and discharging unit is the receiving mode), the receiving unit may convert the ac signal from the charging and discharging coil into a dc signal, and charge the battery of the receiving unit through the wireless charging interface; and under the condition that the charging and discharging coil is connected with the transmitting unit (namely, the working mode of the charging and discharging unit is the transmitting mode), the direct current signal from the external power supply can be converted into an alternating current signal through the transmitting unit, and the alternating current signal is transmitted to the equipment to be charged through the charging and discharging coil connected with the transmitting unit.
The alternating current signal source of the charging and discharging coil has two aspects:
in the first situation, when the terminal is used as a device to be charged and operates in a receiving mode, the ac signal is generated by other wireless charging devices, and the specific generation manner includes, but is not limited to, a forward conversion manner or a flyback conversion manner, which is common in a switching power supply, and the like, and is transmitted to the outside through a coil to which a wireless charging device (i.e., the wireless charging device) belongs, and a charging and discharging coil of the terminal receives the ac signal in an induction manner and realizes charging after ac-dc conversion by a receiving unit;
in the second case, when the terminal is used as a wireless charging device and operates in a transmitting mode, the ac signal is generated by a transmitting unit of the terminal, the specific generation mechanism is the same as the first case, the ac signal is transmitted to the outside through a charging and discharging coil of the terminal, and other devices to be charged receive the ac signal through a receiving coil of the terminal and are charged after internal ac-dc conversion processing.
The alternating current signal of the charging and discharging coil can comprise at least two frequencies, wherein the first frequency corresponds to a wireless charging or wireless power supply working mode and is the working frequency for realizing electric energy transmission; the second frequency corresponds to detection and identification of the wireless charging device and is the working frequency of interaction between the wireless charging device and the device to be charged. For example, in a normal wireless charging or wireless power supply process, the ac signal operates at the second frequency to transmit the identification code and the identity confirmation, and after the confirmation is completed, the ac signal operates at the first frequency to realize wireless power transmission. Preferably, during the period that the alternating current signal works at the first frequency, interaction can be realized through the second frequency, the states of the wireless charging device and the equipment to be charged are confirmed, the interaction process can occur at certain time intervals and is completed in a very short time, and the normal operation of wireless charging or wireless power supply is not influenced.
For example, the terminal may include an external power interface, a charging management unit, a wireless charging interface, a wireless power management unit; the external power interface may be connected to an external power source, which includes a Universal Serial Bus (USB) or an adapter; the charging management unit also comprises a charging mode detection unit which is used for identifying the charging mode and feeding back the current charging state information to the user; the wireless charging interface is connected with the charging management unit and the wireless power management unit. Wherein, the external power interface is connected with the radio power management unit, and the radio power management unit works in two modes: a receive mode and a transmit mode; when the wireless power management unit works in a sending mode, the terminal realizes the function of wireless power supply; and the wireless power management unit may further include a receiving unit, a transmitting unit, a wireless power control unit, a device identification unit, and a coil; the receiving unit is operated in a receiving mode of the radio power management unit; the transmitting unit works in a transmitting mode of the radio power management unit; the wireless power supply control unit is connected with the coil and determines whether the coil is connected with the transmitting unit or the receiving unit according to the result fed back by the equipment identification unit; the transmitting unit and the receiving unit share the same set of coils.
At the moment, when the external power supply interface does not have an external power supply and the terminal is in the effective range of the external wireless charging device, the wireless power supply management unit works in a receiving mode and is connected with the charging management unit through the wireless charging interface to realize wireless charging; and when the external power supply interface is connected with an external power supply and simultaneously connected with the wireless power supply management unit, and other legal devices to be charged exist in the effective charging range of the terminal, the wireless power supply management unit works in a sending mode, and the terminal serves as a wireless charging device to realize wireless power supply for the other legal devices to be charged.
Considering that the battery capacity of the terminal is small at present, although the battery of the terminal can be used for supplying power to the outside, in order to supplement the electric quantity of the battery of the terminal as soon as possible, the external power interface can be preferentially monitored before the current working mode of the wireless charging and discharging unit is determined; and when the external power supply interface has external power supply input and does not detect a wireless signal, entering a wired charging mode. And when the external power interface detects that the external power input is available, if the battery of the device to be charged is fully charged or the device to be charged leaves the effective charging range, entering a wired charging mode to charge the battery of the device to be charged in a wired manner. Therefore, the terminal has the functions of wired charging and wireless charging and also has the functions of wireless charging and wireless power supply, and correspondingly, the terminal comprises three states: wired charging, wireless charging, and wireless power supply. Wherein, the mode of realizing wired charging function can be: the external power supply interface is connected with the charging management unit, and when an external power supply is connected, a wired charging function is achieved.
And in the process that the terminal carries out wired charging on the self battery, if the wireless signal is received and the legal device to be charged is confirmed to exist, the self battery is not charged any more, the wireless power supply mode is switched to, and the wireless power supply is carried out on the device to be charged. Through the mode, when the condition that the equipment to be charged needs to be charged is detected, the equipment to be charged is preferentially powered, and the battery is charged after the charging is finished, so that the user experience is improved. For example, when the wireless power management unit works in the sending mode, the terminal is used as a wireless charging device and is powered by an external power supply, and at the moment, if the device identification unit confirms that a legal device to be charged exists, the terminal does not perform self charging any more and is switched to the wireless power supply mode; and when the battery of the external legal device to be charged is fully charged or leaves the effective charging range of the terminal, the terminal is switched to a wired charging mode to charge the battery of the terminal.
Corresponding to the above method, this embodiment further provides a charging and discharging terminal, which is used to implement the foregoing embodiment and preferred embodiments, and the description of the terminal is omitted for brevity. As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function.
