Next, the power supply device for electronic equipment provided by the present application will be specifically explained.
Fig. 1 shows a schematic structural diagram of a charging control system provided in an embodiment of the present application, and as can be seen from fig. 1, the charging control system includes a charging component 1 and a power receiving component 2, the charging component 1 is disposed in a charging base station, the power receiving component 2 is disposed in a device to be charged, and at least a first connection line, a second connection line, and a third connection line are included between the charging component 1 and the power receiving component 2.
Further, the charging assembly 1 includes a first controller 11, a first communication circuit 12, and a first charging circuit 13, and fig. 2 shows a schematic diagram of the charging assembly 1 provided in this embodiment, where the first controller 11 may be a Micro Controller Unit (MCU) of the charging assembly 1, and may also be another controller connected to the charging assembly 1, and a port of the first communication circuit 12 is denoted by Charge _ RX, and communicates with the outside through the port. Fig. 2 does not show a specific schematic diagram of the first charging circuit 13, and here, the first charging circuit 13 may be a circuit corresponding to an adapter.
The power receiving component 2 according to the embodiment of the present application includes a second communication circuit 21, a second charging circuit 22, and a control circuit 23, fig. 3 shows a schematic diagram of the second communication circuit 21, and fig. 4 shows a schematic diagram of the second charging circuit 22 and the control circuit 23, it should be noted that, for convenience of distinguishing the second charging circuit 22 from the control circuit 23, a dashed-line frame is used for distinguishing in fig. 4, but it should be understood that other devices, such as a second controller 25 and a second diode 27, are also included in the dashed-line frame.
With reference to fig. 1 to 3, the first charging circuit 13 of the charging component 1 and the second charging circuit 22 of the powered component 2 are connected by a first connection line, as an example, a port of the second communication circuit 21 in fig. 3 is represented by COM-SIG, the first communication circuit 12 of the charging component 1 and the second communication circuit 21 of the powered component 2 are connected by ports Charge _ RX, COM-SIG, and a second connection line, and a ground terminal of the charging component 1 and a ground terminal of the powered component 2 are connected by a third connection line, that is, in a state where the charging component 1 and the device to be charged are connected, the charging component 1 and the powered component 2 share one ground terminal and the same signal terminal, so that the charging component 1 and the powered component 2 can communicate through the second connection line, that is, the charging base station and the device to be charged can communicate through the second connection line, so as to implement communication control of the charging base station on the device to be charged.
With continued reference to fig. 2, the charging assembly 1 further includes a first resistor 14, that is, R21 in fig. 2, one end of the first resistor 14 is connected to both the first controller 11 and the first communication circuit 12, the other end of the first resistor 14 is connected to the high-level end (i.e., 5V), the first resistor 14 is a pull-up resistor, and the resistance of the first resistor 14 may be set to 100K Ω. With reference to fig. 3, the power receiving component 2 further includes a second resistor 24, that is, R56 in fig. 3, one end of the second resistor 24 is connected to the second communication circuit 21, the other end of the second resistor 24 is connected to the ground, the second resistor 24 is a pull-down resistor, and the resistance of the second resistor 24 can be set to 1K Ω. Based on this, in the case where the charging base station is connected to the device to be charged, the level signal of the first resistor 14 is a low level signal; in the case where the charging base station is not connected to the device to be charged, the level signal of the first resistor 14 is a high level signal.
In specific implementation, the first controller 11 acquires a first level signal of the first resistor 14, and determines that the charging base station is connected with the device to be charged when the first level signal is a low level signal; and in the case that the first level signal is a high level signal, determining that the charging base station is not connected with the device to be charged.
Further, in the case where the charging base station is connected to the device to be charged, the first controller 11 controls the first communication circuit 12 to switch from the off state to the communication state, and establishes the communication connection between the first communication circuit 12 and the second communication circuit 21 in the power receiving component 2, thereby further communication control of the charging base station to the device to be charged can be realized.
Under the condition that the charging base station is connected with the device to be charged and the first communication circuit is connected with the second communication circuit, the first controller 11 further controls the first charging circuit 13 to start up, so that the first charging circuit 13 supplies power to the second charging circuit 22, that is, the first charging circuit 13 is controlled to transmit electric quantity to the second charging circuit 22, and the purpose that the charging base station supplies power to the device to be powered is achieved.
Therefore, the equipment to be powered transmits the current electric quantity of the battery pack 29 to the charging base station through the first communication circuit 12 and the second communication circuit 21, when the current electric quantity is full, the charging base station controls the first charging circuit 13 to be closed, the problem that power consumption is caused when the charging base station is powered off under the condition that the equipment to be powered does not need to be charged is solved, and the purposes of reducing power consumption and avoiding resource waste are achieved.
Referring to fig. 4, the power receiving component 2 further includes a second diode 27, i.e., D3 in fig. 4, the second diode 27 is used for connecting the second charging circuit 22 and the control circuit 23, and specifically, an anode of the second diode 27 is connected to an output end of the second charging circuit 22, and referring to the example shown in fig. 4, an anode of the second diode 27 is connected to the socket CN21 to receive the power provided by the socket CN21, and a cathode of the second diode 27 is connected to an input end of the control circuit 23, so that the second charging circuit 22 transmits the power to the control circuit 23 through the second diode 27. Meanwhile, the second diode 27 can prevent the power in the control circuit 23 from being lost through the second charging circuit 22. It should be noted that the second charging circuit 22 is connected to the second controller 25 through POWER-EN, so that the second controller 25 determines whether there is POWER in the second charging circuit 22.
Here, when the second charging circuit 22 receives the power provided by the first charging circuit 13, accordingly, the diode D3 in fig. 4 is turned on, so that the second charging circuit 22 transmits the power to the control circuit 23, and the control circuit 23 is powered on.
The power receiving component 2 according to the embodiment of the present application further includes a second controller 25 and a first diode 26, for example, the first diode 26 is D12 shown in fig. 3, and referring to fig. 3 and 4 respectively, the second controller 25 is connected to the anode of the first diode 26 through a port Bottom _ TX/RX, and the cathode of the first diode 26 is connected to the second communication circuit 21, so that the second controller 25 can receive a signal transmitted by the second communication circuit 21 and send a signal to the second communication circuit 21, and the like. Here, since the internal resistance of the second controller 25 of the power receiving component 2 is in an indeterminate state when the device to be charged is in the power-off state, the first diode 26 is provided in the power receiving component 2 to ensure that the charging component 1 can detect a low-level signal when the device to be charged is connected to the charging base station through the first diode 26, and further ensure that the charging base station can supply power to the device to be charged when the device to be charged is connected to the charging base station; and, the influence of the internal resistance of the second controller 25 on the pull-down effect of the second resistor 24 is avoided. As can be understood from fig. 1 to 4, the low-level signal is a level signal of the first resistor 14, the first communication circuit 12, and the second communication circuit 21.
Further, the control circuit 23 supplies power to the second controller 25 and the second communication circuit 21 simultaneously with the charging assembly 1 after being started by power supply, so that the second controller 25 controls the second communication circuit 21 to establish a communication connection with the first communication circuit 12.
When the power receiving component 2 in the embodiment of the present application sends a high level to the second communication circuit 21, the first diode 26 is turned on, and the output of the second communication circuit 21 appears as a high level; when the power receiving component 2 sends a low level to the second communication circuit 21, the first diode 26 is not turned on, and the pull-down resistor makes the output of the second communication circuit 21 appear as a low level; when the charging component 1 sends a high level to the first communication circuit 12, the first diode 26 is not turned on, and the pull-up resistor inside the second controller 25 of the powered component 2 causes the powered component 2 to detect the high level, that is, the powered component 2 defaults to the high level when the first diode 26 is not turned on; when the charging component 1 sends a low level to the first communication circuit 12, the first diode 26 is turned on, and the second resistor 24 connected to the ground enables the pin of the power receiving component 2 to detect a low level, i.e. the power receiving component 2 detects a low level.
Optionally, the control circuit 23 includes a field effect transistor and a POWER switch, referring to fig. 4, the field effect transistor is M3, the POWER switch is represented by a POWER-SW port, a gate of the field effect transistor is connected to one end of the POWER switch, a drain of the field effect transistor is connected to one end of the voltage stabilizing circuit 28, and the other end of the voltage stabilizing circuit 28 is connected to the second controller 25 through the POWER-FD, so that after the field effect transistor M3 is disconnected, the second controller 25 controls the POWER-FD to be at a high level, and further, the electric quantity in the control circuit 23 is transmitted to the outside, and further, the purpose of low POWER consumption of the control circuit 23 during POWER failure is achieved. The voltage stabilizing circuit 28 includes a single chip microcomputer, such as the IC3 shown in fig. 4, to make the power provided by the socket CN21 and/or the battery pack 29 reach the actually required power through the IC 3. The source of the field effect transistor is connected to a battery pack 29 for storing electric power so that when the second diode 27 is turned on, the socket CN21 can charge the battery pack 29, and the other end of the power switch is connected to the second controller 25. In a specific implementation, the second controller 25 receives the Power provided by the second charging circuit 22, so that the second controller 25 is powered on, and the Power-SW is controlled to be at a high level, that is, the Power switch is controlled to be turned on, at this time, the field effect transistor is turned on, and the control circuit 23 supplies Power to the second controller 25 through the field effect transistor. The gate of the field effect transistor shown in fig. 4 is also connected to one terminal POWER-ON of an external switch to enable the switching of the field effect transistor M3 to be manually controlled.
In an implementation, the second controller 25 collects the power information of the control circuit 23 in real time or periodically, the power information includes the current power of the battery pack 29, the voltage/current provided to the battery pack 29, the time period for supplying power to the battery pack 29, and the like, and transmits the power information to the first controller 11 through the second communication circuit 21 and the first communication circuit 12.
After receiving the power information through the first communication circuit 12, the first controller 11 controls, according to the power information, whether the first charging circuit 13 stops supplying power to the second charging circuit 22 based on the power supply rule, so that the charging component 1 controls the communication of the powered component 2 through the first communication circuit 12 and the second communication circuit 21, that is, the communication of the charging base station to the device to be charged is controlled.
Alternatively, upon determining that the current charge of the battery pack 29 is greater than 98% of the rated charge of the battery pack 29, the second charging circuit 22 is powered off; when it is determined that the time period for supplying power to the battery pack 29 is longer than the preset time period, the power supply to the second charging circuit 22 is stopped, and the like.
As an example, the first controller 11 may further receive an operation instruction, and generate first communication information according to the operation instruction, where the operation instruction may be generated by a user performing a preset operation on the charging base station, the preset operation is, for example, pressing a preset button, clicking a preset icon on a touch screen, and the like, the first communication information may instruct the device to be charged to perform another program, and for example, when the device to be charged is a floor washing machine, the first communication information may instruct the floor washing machine to perform self-cleaning, optimize the battery pack 29, automatically dry, replenish clean water, and the like.
The first controller 11 transmits the first communication information to the second controller 25 through the first communication circuit 12 and the second communication circuit 21, and the second controller 25 responds to the first communication information to perform the operation indicated by the first communication information, that is, to realize effective communication between the charging base station and the device to be charged, wherein the charging base station includes the first controller and the first communication circuit, and the device to be charged includes the second controller and the second communication circuit.
In a specific implementation, the second controller 25 transmits the generated second communication information to the first controller 11 based on a preset period, for example, the preset period is 250 ms, that is, one second communication information is generated every 250 ms, and is transmitted to the first controller 11 through the second communication circuit 21 and the first communication circuit 12, so that the first controller 11 determines that the device to be charged and the charging base station still maintain connection, and further, communication connection between the second communication circuit 21 and the first communication circuit 12 is still maintained.
Correspondingly, if the first controller 11 does not receive the second communication information within the preset time period, at this time, the first controller 11 determines that the charging base station is not connected to the device to be charged, and in order to avoid power loss caused by the fact that the first charging circuit 13 is still discharged, the first controller 11 controls the first charging circuit 13 to be closed, so that the purpose of avoiding power consumption waste is achieved; meanwhile, if other programs in execution exist, the execution is controlled to stop.
According to the embodiment of the application, through the first communication circuit 12 in the charging component 1 and the second communication circuit 21 in the power receiving component 2, even if the device to be charged is in a shutdown state, the communication between the charging base station and the device to be charged can be realized, and the functional communication between the charging base station and the device to be charged can be achieved based on the established communication connection, so that the purpose of avoiding power consumption waste is achieved.
