Detailed Description
In order to make those skilled in the art better understand the technical solutions in the embodiments of the present specification, the technical solutions in the embodiments of the present specification will be described in detail below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of protection.
When the power supply is wireless, energy is transmitted between the power supply equipment end and the electric equipment end in a near-field induction mode, so that the power supply equipment end and the electric equipment end are not connected by using physical contact points such as electric wires and the like, and the non-conductive contact points can be exposed, so that the power supply equipment end and the electric equipment end are widely applied to equipment charging, especially some intelligent equipment.
Current smart devices have been widely used in various fields. When the intelligent equipment works, the intelligent equipment needs to be moved actively or passively. For a smart device that needs to move, the range of movement that can be performed by the smart device is usually expected, for example, the range of movement of a sweeping robot is usually a certain room; the range of motion of some industrial robots is within a fixed plant. Under the situation, the power consumption of a plurality of devices is high, and if wireless charging is adopted, the charging is carried out after the power is not available, so that the problems of low power and incapability of being fully charged often occur, and the normal requirement cannot be met.
Based on this, the embodiments of the present specification provide a wireless charging scheme, which can perform dynamic charging according to the power consumption of a device, as shown in fig. 1, where fig. 1 is an exemplary schematic diagram of a scenario application related to the embodiments of the present specification. The movable equipment in the schematic diagram can be actively moved, for example, the sweeping robot actively moves within a certain range according to a specified rule; it may also be passive, for example, a smartphone being carried by a user moving in a room. The power supply terminal in the schematic diagram may be a storage battery having an energy storage function, or may be connected to the commercial power through a wire to supply power, and the like. While the power consuming terminal (not shown in figure 1) is fixed to the mobile device and moves with it. In addition, the mobile device in this schematic may be a smart device such as a robot, smart phone, etc., or a generally conventional non-smart device.
The technical solutions provided by the embodiments of the present specification are described in detail below with reference to the accompanying drawings, as shown in fig. 2, fig. 2 is a schematic flow chart of a wireless charging method of a power supply terminal provided by the embodiments of the present specification, and the flow chart specifically includes the following steps:
s201, a power supply terminal generates and broadcasts power supply data, wherein the power supply data comprise power supply handshake data.
When the power supply terminal broadcasts the power supply data, the power supply terminal can be in a normal working state. Furthermore, the device can be in a dormant working state. The sent power supply data only needs to contain power supply handshake data which can be responded by the power utilization end, the format and the related content of the power supply data and the power supply handshake data contained in the power supply data do not need to be fixed, and the power supply data are specifically set by a user according to the environment and the actual situation of equipment. The broadcast range of the powering data does not normally exceed the wirelessly chargeable signal range.
S203, the power supply end receives and analyzes power utilization data fed back by the power utilization end, wherein the power utilization data at least comprise handshake response data representing power supply requirements and energy value data representing energy required by the power utilization end.
The handshake response data is for power supply handshake data, and when the power supply end receives the handshake response data, it indicates that one device in the surrounding environment needs to be charged. And the energy value data represents the required energy of the power utilization end and is used as a relevant basis for charging the power supply end. Then the power supply terminal starts to start charging the device at this time.
S205, determining a first chargeable signal, wherein the larger the energy value data is, the larger the charging power of the first chargeable signal is.
The chargeable first signal may be an electromagnetic wave signal satisfying various standards in wireless charging, including but not limited to Qi standard, pma (power materials Alliance) standard and A4WP (Alliance for WirelessPower) standard, or an electromagnetic signal obtained in a customized manner. The power utilization end can receive the first signal and charge, at the moment, the charging power of the first signal is determined by the power supply end according to the energy value data, and the charging power of the first signal which can be charged is larger when the energy value data is larger, so that the energy transmission is realized according to the requirement of the power utilization end.
S207, the power supply terminal sends the first chargeable signal, so that the power utilization terminal receives the first chargeable signal for charging. Specifically, the power supply terminal can detect the surrounding environment, locate the specific position of the power utilization terminal, and then adjust the transmission direction of the first chargeable signal so as to charge the power utilization terminal, or can broadcast the transmitted energy signal to start energy transmission.
In practical applications, the power supply terminal may generate and broadcast the power supply data, or the power supply terminal may generate a power supply data at regular time (for example, every 30 minutes) in a dormant operating state, and also generate a second signal that can be charged by the power supply terminal, and by loading the power supply data into the second signal that can be charged, generate a second signal that can be charged and carries the power supply data, and broadcast the second signal that can be charged and carries the power supply data. In this way, the energy carried by the second signal can be very weak energy, and the power supply terminal can perform timed broadcasting in a dormant state, so that energy is saved.
As a specific implementation manner, when the power supply terminal supplies power, the waveform of the power supply data sent by the power supply terminal may be implemented as follows, as shown in fig. 3, and fig. 3 is a schematic diagram of generating the power supply data provided in the embodiments of the present specification. The method comprises the steps that a data stream is generated by serial data output at a power supply end, the generated data stream enters an I/O interruption acquisition module, when the data stream is turned from 0 to 1 or from 1 to 0, the data stream is captured by the I/O interruption acquisition module, in a capturing program, the frequency of a timer is updated, two different timer frequencies correspond to two different waveforms, namely a waveform 1 and a waveform 2, after the frequency of the timer is updated, the output end of the timer outputs a corresponding waveform according to a frequency value, the waveform is a modulated data stream signal and can be loaded on energy and transmitted out through a transmitting coil.
In addition, when the power supply end receives the feedback of a certain power utilization end, the broadcasting of the power supply data can be suspended, and the broadcasting can be resumed when the power utilization data fed back by the power utilization end is not received any more. Avoid a plurality of equipment to get into the process of charging simultaneously, avoid the output of first signal disorderly.
The technical scheme of the power utilization end provided by the embodiment of the specification is provided. As shown in fig. 4, fig. 4 is a schematic flowchart of a wireless charging method of a power consumption end provided in the embodiment of the present specification, where the flowchart specifically includes the following steps:
s401, receiving power supply data broadcasted by a power supply end, wherein the power supply data comprises power supply handshake data.
And S403, the power utilization end judges whether charging is needed or not according to the residual capacity of the battery in the mobile equipment, and if so, power utilization data are generated, wherein the power utilization data at least comprise handshake response data representing that power supply is needed and energy value data representing the energy needed by the power utilization end.
The energy value data is data related to the remaining capacity of the battery in the mobile device, and may be an absolute value (for example, power consumption amount 1000mAh) or a relative value (for example, power consumption ratio 70%). The available charge of the battery may be dynamically changed as the operation of the power consuming terminal proceeds and the charging of the charging terminal is performed. Based on this, the energy value data fed back to the power supply terminal by the power consumption terminal may be dynamically changed based on the current battery remaining capacity of the battery, and the power consumption data including the current energy value data may be generated. Therefore, the power supply end can change the output energy according to the analyzed energy value, and the energy output by the power supply end and the energy used by the power utilization end reach dynamic balance.
Of course, if no charging is required, handshake response data including a representation that no power is required may be sent to the power supply terminal, or no power usage data may be sent to the power supply terminal.
S405, the power utilization end sends the power utilization data to a power supply end.
S407, receiving a first signal which is transmitted by a power supply terminal and can be charged, and charging a battery in the mobile equipment.
In practical applications, the power utilization end is not necessarily directly within the range of the power supply end, and the power supply end is not necessarily directly in a normal working state from the beginning, for example, when the power supply end is in a sleep state and intermittently transmits a weak energy signal carrying power supply data (i.e., a second chargeable signal), at this time, the power utilization end may receive the second chargeable signal carrying the power supply data broadcasted by the power supply end during a continuous moving process, and further extract the power supply data carried in the second chargeable signal, so as to perform feedback to start a charging process.
In a specific implementation manner, when receiving and analyzing the power supply data broadcasted by the power supply end, the power consumption end may process the data stream signal, as shown in fig. 5, where fig. 5 is a schematic diagram of analyzing the power supply data by the power consumption end provided in the embodiments of this specification. A square wave as shown in waveform 4 can be obtained first. Sending the waveform shown in the waveform 4 into the hardware timer 1, using the rising edge signal of the waveform as the reset signal of the hardware timer 1, setting the comparison value of the hardware timer 1 between the frequencies of the waveform 1 and the waveform 2 shown in fig. 3, generating the waveform shown in the waveform 5, sending the waveform shown in the waveform 5 into the hardware timer 2, using the rising edge of the waveform as the reset signal of the hardware timer 2, setting the comparison value of the hardware timer 2 to be larger than the larger value of the frequencies of the waveform 1 and the waveform 2, generating the digital signal shown in the waveform 6, which is the restoration of the serial data of the power supply end, sending the data into the serial data input port of the power utilization end, namely analyzing the data sent by the power supply end.
The signal is broadcasted to the periphery through the power supply end, the power utilization end judges whether the power utilization end needs to be charged when receiving the broadcast information number, if yes, corresponding power utilization data are returned to the power supply end according to the power consumption situation of the power utilization end, and therefore the power supply end can conduct dynamic wireless charging on the power utilization end according to the actual situation.
