The first power supply battery pack 100 and the second power supply battery pack 200 are electrically connected to the control system 500 in parallel, respectively, and are configured to supply power to the electronic device under the control of the control system 500; the first power supply battery 100 is mainly used as a backup power source of the electronic device, and may be a dry battery. The dry battery is an electrochemical cell for generating direct current by using a paste electrolyte, and is called a "dry battery" because the electrolyte is an immobile paste, and functions to provide a backup power in a state where the second power supply battery 200 is not charged or is short of capacity. When the power is supplied as a backup power, the power is not always supplied, and therefore the power display is not necessarily the actual power.
The second power supply battery 200 may be a lithium battery as a main power supply of the electronic device. Lithium batteries generally use manganese dioxide as a positive electrode material, metal lithium or an alloy metal thereof as a negative electrode material, and a nonaqueous electrolyte solution.
In practical circuit application, the first power supply battery pack 100 and the second power supply battery pack 200 refer to a device having two power sources, which are independent of each other, the first power supply battery pack 100 is used as an alternative power source for the second power supply battery pack 200, and in case that the second power supply battery pack 200 is not in place or is insufficient in power, the circuit automatically switches from a main power source to a standby power source for power supply. Of course, the electronic device may also include a third power supply battery.
The detection circuit 300 and the power detection circuit 400 are connected in parallel between the first power supply battery pack 100 and the control system 500;
the detection circuit 300 and the power detection circuit 400 are independent circuits when either circuit is in an off state, and the other circuit is independently operable. The detection circuit 300 and the power detection circuit 400 are located between the first power supply battery pack 100 and the control system 500 in the entire circuit configuration diagram.
The detection circuit 300 is configured to be in a connected state or a disconnected state under the control of the control system 500, and trigger the first power supply battery pack 100 to be in a simulated operation state when in the connected state;
the detection circuit 300 performs circuit detection on the first power supply battery pack 100, the detection circuit 300 and the first power supply battery pack 100 form a complete circuit diagram through the control system 500, when the control system 500 transmits an enabling signal to the detection circuit 300, the detection circuit 300 is in a connected state, the detection circuit 300 carries out pull load on the first power supply battery pack 100, and the first power supply battery pack 100 supplies current to the detection circuit, so that detection is achieved.
The power detection circuit 400 is configured to detect the power of the first power supply battery pack 100 under the control of the control system 500;
the power detection circuit 400 mainly detects the power of the first power supply battery pack 100. The power detection circuit 400 transmits an enable signal to the power detection circuit 400 through the control system 500 to perform power detection on the first power supply battery pack 100.
The control system 500 starts the first power supply battery pack 100 to supply power to the electronic device, and determines whether the first power supply battery pack 100 is in a virtual power state according to the power detection result of the power detection circuit 400.
The control system 500 is an operation performed to bring the object to be controlled to a predetermined ideal state, and at the same time, the control system 500 is caused to bring the object to be controlled to a desired stable state. When the second power supply battery pack 200 does not satisfy the condition and cannot supply power to the electronic device, the control system 500 may transmit an enable signal to the first power supply battery pack 100 to supply power to the electronic device, and at the same time, the control system 500 may trigger the power detection circuit 400 to detect the power of the first power supply battery pack 100, and determine the state of the first power supply battery pack 100 according to the result of the power detection circuit 400.
The specific connection modes between the first power supply battery pack 100, the second power supply battery pack 200 and the detection circuit 300, the power detection circuit 400 and the control system 500 are not limited herein.
Adopt the electronic equipment of above-mentioned structure, detection circuit carries out the pulling load to first power supply group battery, carries out the electric quantity to first power supply group battery again and detects to can effectively distinguish whether first power supply group battery is in the virtual electric state, can exert first power supply group battery and provide the effect of effective power supply as stand-by battery for electronic equipment then.
Based on the control of the control system to the power supply battery pack, the detection circuit and the electric quantity detection circuit, the technical scheme is implemented, and therefore, the following further detailed description is given to the working process of the control system, and the technical scheme specifically comprises the following steps:
1. to control system based on electric quantity detection circuit's electric quantity testing result, confirm whether first power supply battery group is in virtual electric state, its concrete implementation includes:
and determining whether the first power supply battery pack is in a virtual electricity state or not according to a first electricity value detected by the electricity detection circuit when the detection circuit is in an off state, a second electricity value detected by the electricity detection circuit when the detection circuit is in a on state and the time difference of two detections.
The control system 500 determines whether the first power supply battery pack 100 is in a virtual power state by detecting the power amount of the first power supply battery pack 100 in different states. The virtual electricity state generally means that the electricity value detected by the power supply battery pack is false, for example, the actual electricity of the power supply battery pack is 5V, but the detection result is 20V. The result of the electric quantity detection may be an actual electric quantity value, or may be a result based on electric quantity value conversion, such as percentage. To avoid a virtual electrical state, two electrical measurements are thus introduced by detecting a change in state of the circuit. If the power of the first power supply battery pack 100 suddenly drops before and after the state change of the detection circuit, the first power supply battery pack 100 is considered to be in a virtual power state. The sudden drop specifically means that the electric quantity detection result is greatly changed in a short time.
For example, the control system detects a difference of 50 percent in a state where the detection circuit is in an off state and the first electric quantity value obtained by the electric quantity detection circuit is 60 percent, and then detects a second electric quantity value obtained by the on state and the second electric quantity value is 10 percent, and the state transition time of the detection circuit is short, namely, the state where the electric quantity is suddenly reduced.
2. For when the detection circuit is in a connected state or an disconnected state, the specific way is as follows:
the control system is specifically configured to control the detection circuit to be in a connected state after the first power supply battery pack is started to supply power to the electronic device; and when the first power supply battery pack does not supply power to the electronic equipment, controlling the detection circuit to be in an off state.
The detection circuit 500 is not in an operating state at ordinary times, and is in a simulated operating state only when it is necessary to determine whether the electric quantity of the first power supply battery pack 100 is in a virtual state, and the detection circuit 300 needs the first power supply battery pack 100 to provide the electric quantity for the detection circuit in the operating state, and consumes the electric quantity all the time if the first power supply battery pack is in the operating state all the time. Due to the design of the above manner, the detection circuit 300 is in the working state only when the first power supply battery pack 100 needs to be powered and the first power supply battery pack 100 needs to be subjected to electric quantity detection.
3. For a subsequent work flow that the first power supply battery 100 set is not in a virtual power state, the specific method is as follows:
and the control system controls the detection circuit to be in an off state and determines the switching time of the detection circuit in the next on state according to the electric quantity detection result.
When the first power supply battery pack 100 is not in the virtual state, the operation of the detection circuit 300 is finished, and the control system 300 controls the detection circuit 300 to be in the off state, because the first power supply battery pack 100 consumes the electric quantity all the time when being in the on state.
The switching time for the next communication state is determined according to the electric quantity detection result. Specifically, the first power supply battery pack has a working power consumption and a standby power consumption in a working state and a non-working state respectively, an average value can be obtained according to the working power consumption and the standby power consumption, the electric quantity value at the moment is measured according to the electric quantity detection circuit, and the quotient of the average value and the electric quantity value is the conversion time interval.
For example, the average value is 6.4 according to the specific operating power consumption and standby power consumption, the electric quantity value is 80 percent, the quotient of the two is 8, the unit is day, so that after the next measurement is 8 days, the time interval is a reference, and the electric quantity detection can also be performed in a connected state in advance.
4. When the detection result shows that the device is in the virtual power state, the specific operation is as follows: as shown in fig. 2, fig. 2 is a schematic diagram of an internal architecture of another electronic device according to an embodiment of the present invention.
The electronic device further includes a plug detection circuit 600 connected between the first power supply battery pack 100 and the control system 500;
the plug detection circuit 600 is a circuit for detecting whether or not the battery is replaced when the first power supply battery pack 100 is in a virtual state.
The control system 500 is further configured to, when it is determined that the first power supply battery pack 100 is in a virtual state, send a prompt message until a pull-out instruction sent by the pull-plug detection circuit 600 is received; the pull-out indication is used for representing that the first power supply battery pack is pulled out of the electronic equipment.
After the control system 500 detects that the first power supply battery pack 100 is in the virtual power state, the plug detection circuit 600 detects whether the first power supply battery pack 100 is replaced with a battery. When the plugging signal is detected, the battery is replaced, and when the plugging signal is not detected, the plugging signal is continuously waited.
5. The control system controls the plug detection circuit and is embodied in that:
the control system is further configured to control the detection circuit to be in a connected state when receiving the insertion instruction sent by the plug detection circuit.
After the first power supply battery pack 100 is replaced, the replaced first power supply battery pack 100 needs to be detected again, so that it can be determined whether the replaced first power supply battery pack 100 is not in a virtual power state. When the plugging signal is detected, the control system needs to make the detection circuit 300 be in a connected state, pull the first power supply battery pack 100, and then perform power detection on the first power supply battery pack 100 based on the power detection circuit 400.
