The system circuit 303 is an existing system circuit, and at least includes a central processing unit, a memory, a display circuit, a radio frequency circuit, and the like.
As shown in fig. 1, the method includes:
step 101: acquiring an attribute of a control signal, the control signal being determined by a control circuit;
here, the control signal is generated by a control circuit. The properties of the control signal comprise at least a first property and a second property.
Step 102: determining the working state of the switch circuit according to the attribute of the control signal;

Step 103: determining the working state of a system circuit according to the working state of the switch circuit;
here, the operating states of the system circuit include at least: an active state and an inactive state. In the operating state, the system circuit performs normal processing functions. In the non-operating state, this corresponds to the system circuit being in an off state. The operating state of the system circuit is determined in dependence on the operating state of the switching circuit.
The execution subject of steps 101-103 is a control device, and may also be an electronic device provided with a control device.
In the embodiment of the invention, a control circuit and a switch circuit are added between the existing system circuit and a battery (circuit), a control signal determined by the control circuit is used for controlling the working state of the switch circuit, and the working state of the system circuit is determined according to the working state of the switch circuit. The working state of the switch circuit is determined by the attribute of the control signal, when the switch circuit is in the off state, the battery electric quantity is blocked by the switch circuit in the off state and does not flow to the system circuit any more, so that the switch-off of a path of the battery electric quantity to the system circuit is realized, the flow of the battery electric quantity to the system circuit in a shift mode is truly avoided, and the purpose of saving the electric quantity is achieved.
It should be understood by those skilled in the art that the shift mode is a power saving mode, and can be understood as follows: in this mode, most devices such as control circuits, switching circuits, and system circuits operate with less power than in normal operation, i.e., the mode allows for both normal operation of the device and power savings.
As a preferred embodiment, the present solution proposes two methods for controlling a device to enter a shift mode, where the control device may enter the shift mode based on any one of the following methods:
the first method is as follows: and acquiring an operation attribute of a preset operation source, wherein the operation attribute is at least the operation time of the preset operation source, judging whether the operation attribute meets a first preset condition, and if so, entering a shift mode by the control equipment. Based on the shift mode, the control device performs the aforementioned steps 101-103.
The second method is as follows: and acquiring a control instruction, wherein the control instruction is an instruction for instructing the control equipment to enter a shift mode, and the control instruction is responded to enter the shift mode. Based on the shift mode, the control device performs the aforementioned steps 101-103.
In the first method, an operation Key (a predetermined operation source) is preset for the control device to be able to enter a shift mode, and the operation Key can be set independently or can be multiplexed with an existing Key of the control device, such as a Power Key (Power Key); the Power Key Key may be a physical Key or a virtual Key. Taking multiplexing the Power Key as an example, a user performs a pressing operation on the Power Key, when the control device detects the pressing operation of the Power Key, the control device detects the operation time of the operation, judges whether the operation time is more than or equal to 12s (whether the operation attribute meets a first preset condition), if so, determines that the pressing is an operation for indicating the control device to enter a shift mode, the control device enters the shift mode, and the control circuit and the switch circuit both work with less Power than under the normal working condition. If the operation time is not more than 12s, further judging whether the operation time is within 2s-3s or 8s-12s, and if the operation time is within 2s-3s, determining that the pressing is an operation for indicating the start-up or the shut-down of the control equipment. If the pressing is within 8s-12s, the pressing is determined to be an operation for instructing the control device to perform forced on-off. In this scheme, for the situation of key multiplexing, the distinction of different functions of the keys is mainly considered, and different functions are distinguished from the operation duration, and in addition, the different functions can be distinguished from other operation attributes such as the operation times and the operation tracks. Of course, the above times such as 2s-3s, 8s-12s, 12s are only a specific example, and are not limited to the present invention, and different functions of the Power Key can be distinguished.
In the second method, the control instruction may be sent by a central processing unit CPU in a system circuit to a control device through a predetermined interface such as a general purpose input/output (GPIO, general Purpose Input Output) interface, and the control device acquires the control command by receiving the control command and enters a shift mode in response to the control command.
Correspondingly, the embodiment of the invention also provides two methods for exiting the shift mode, which are as follows:
the first exit method: and when the control device is in the shift mode, acquiring the operation attribute of the predetermined operation source, judging whether the operation attribute meets a second predetermined condition, and if so, exiting the shift mode by the control device. After exiting the shift mode, the system circuit and the switch circuit enter a normal working state, and corresponding task processing is carried out with normal power.
The second exit method: and monitoring whether a charging power supply is plugged in, generating an exit instruction when the charging power supply is plugged in, and responding to the exit instruction, and exiting the shift mode by the control equipment.
In the first exit method, similar to the first entry method, taking multiplexing the Power Key as an example, when in the shift mode, a pressing operation of the Power Key by the user is detected, when the control device detects the pressing operation of the Power Key, an operation time of the operation is detected, whether the operation time is equal to or longer than 12s (whether the operation attribute satisfies a second predetermined condition) is judged, if yes, the operation time is determined to be an operation for instructing the control device to exit the shift mode, the control device exits the shift mode, and the control circuit and the switch circuit are switched from adopting smaller Power to adopting larger Power (normal Power) to operate.
In the second exit method, whether a charging source such as a charger is inserted is monitored, and when the detection is on occasion, an exit command is generated, and the control device exits the shift mode in response to the exit command.
The two methods for entering the shift mode are easy to realize, simple and feasible, and the usability of the control equipment is greatly improved.
The present invention provides a second embodiment of a control method, as shown in fig. 2, the method comprising:
step 201: acquiring an attribute of a control signal, the control signal being determined by a control circuit;
here, the properties of the control signal include at least a first property and a second property. For example, a first attribute value of "0" and a second attribute value of "1", the two attribute values representing two processing logics; vice versa. The attribute value of the control signal is determined based at least on the first sub-signal and the second sub-signal.
As shown in fig. 4, the control circuit at least includes a charging sub-circuit and a control sub-circuit;
wherein the first sub-signal is determined by the charging sub-circuit and the second sub-signal is determined by the control sub-circuit. I.e. the value of the property of the control signal is determined by the first sub-signal given by the charging sub-circuit and the second sub-signal given by the control sub-circuit.
Further, performing a predetermined operation, such as a nand operation, on the first sub-signal and the second sub-signal to obtain an operation result; and determining the attribute value of the control signal based on the operation result. This process may be implemented by sub-operation circuitry in the control circuitry, as shown in fig. 4.
For example, the first sub-signal given by the charging sub-circuit may take on a value of "0" or "1", and the second sub-signal given by the control sub-circuit may take on a value of "0" or "1". Taking the first sub-signal and the second sub-signal as '1', and performing NAND operation on the '1' and the '1' to obtain a budget result '0', namely, the attribute value of the control signal is logic '0'. Taking the first sub-signal and the second sub-signal as '0', and performing NAND operation on the '0' and the '0' to obtain a budget result '1', namely the attribute value of the control signal is logic '1'. Taking the example that the first sub-signal is "0" and the second sub-signal is "1", performing NAND operation on the "0" and the "1" to obtain a budget result "1", namely, the attribute value of the control signal is logic "1".
It should be understood by those skilled in the art that "0" and "1" in this embodiment are all logical values, and are not natural values.
Step 202: when the attribute of the control signal is a first attribute, determining that the switch circuit is in a conducting state; when the attribute of the control signal is the second attribute, the switch circuit is determined to be in an off state.
Here, when the attribute value of the control signal is a first attribute value, the switch circuit is controlled to be in a conducting state; and when the attribute value of the control signal is a second attribute value, controlling the switch circuit to be in a closed state.
Step 203: when the switch circuit is in a conducting state, determining that the system circuit is in a working state; and when the switch circuit is in a closed state, determining that the system circuit is in a non-working state.
Here, when the switch circuit is in a conducting state, the path from the battery circuit to the system circuit is not blocked by the switch circuit, the battery circuit can normally supply power to the system circuit, and the system circuit is in a normal working state. When the switch circuit is in a closed state, the path from the battery circuit to the system circuit is blocked by the switch circuit, so that the electricity quantity in the shift mode is successfully prevented from flowing into the system circuit, and at the moment, the system circuit is in the closed state in consideration of electricity quantity saving in the shift mode.
The execution subject of steps 201-203 is a control device, and may also be an electronic device provided with a control device.
In summary, in the scheme, the control signal for controlling the switch circuit to be turned off and turned on is obtained through the nand operation of the first sub-signal given by the charging sub-circuit and the second sub-signal given by the control sub-signal; when the switch circuit is in a closed state, the closing of the switch circuit blocks the inflow of the battery electric quantity to the system circuit, so that the control equipment can avoid the inflow of the battery electric quantity to the system circuit in a shift mode. When the switch circuit is in a conducting state, the battery circuit supplies power to the system circuit normally, so that the control equipment works normally.
The present scheme is described in detail below with reference to fig. 5 and 6.
In this embodiment, the charge sub-Circuit is taken as a charge IC, the Control sub-Circuit is taken as a Control IC, and the nand operation is implemented by a Logic Circuit (which can be regarded as an operation sub-Circuit in the Control Circuit). The switching circuit is realized by a field effect transistor Mosfet. The Mosfet tube can be of N type or P type, in this scheme, taking N type as an example, the Gate electrode Gate of the Mosfet tube is connected with the output of the Logic Circuit, the drain electrode D of the Mosfet tube is connected with the overvoltage protection Circuit, and the Gate electrode S of the Mosfet tube is connected with the system Circuit. Among them, the overvoltage protection circuit has a function of avoiding the problem of device damage caused by excessively high voltage and current when the charger is suddenly inserted. Whether the charger is plugged in is given by the universal serial bus USB Con signal. A battery field effect transistor (battery Mosfet) is an existing part, and can be regarded as a part of a battery circuit, which cannot completely block the electric quantity of a battery to a system circuit.
The overvoltage protection circuit, the USB Con and the battery Mosfet are all existing parts in the prior art, and the scheme is illustrated in the drawings, so that the description is only for better specific implementation of the scheme, and the functions of the above parts are shown in the related description, and are not focused herein. The implementation function of the Control IC in the scheme can be provided by the existing circuit or chip of the Control equipment, and a new circuit or chip is not required to be additionally arranged, so that hardware resources can be effectively saved.
First, the control device detects whether the shift mode can be entered. Taking the Power Key as an entity Key arranged outside the control device as an example, the user presses the Power Key, the control device detects the operation time of the operation, judges whether the operation time is more than or equal to 12s (whether the operation attribute meets a first preset condition), and supposedly presses the Power Key 13s by the user, the control device considers that the pressing is an operation for indicating the user to enter a shift mode, and the control device enters the shift mode. In this mode, the Charger IC, control IC, logic Circuit and system Circuit all operate at a lower power. The above scheme may be implemented as a specific implementation of the first method for entering the shift mode.
The Control device detects a signal value (first sub-signal) given by the Charger IC, a signal value (second sub-signal) given by the Control IC. Assuming that the first sub-signal and the second sub-signal are both Logic '1', the charge IC and the Control IC both give high-level signals, after the Logic Circuit performs NAND Logic operation on the 2 high-level signals, a Logic value '0' is obtained, the Logic value '0' is input to the gate electrode of the Mosfet tube by the Logic Circuit, the gate electrode is pulled down, the drain electrode is connected with the battery, and the Mosfet tube is in a closed state. The Mosfet tube is in a closed state, which is equivalent to the path from the battery to the system circuit being blocked, so that the battery power cannot leak from the battery to the system circuit. In this case, to achieve power saving in the shift mode, the system circuit may be turned off.
If the Control device is to exit the shift mode, a charger may be inserted, when the charger is inserted, the USB Con signal is pulled high (corresponding to giving a Control instruction for instructing the Control device to exit the shift mode), the signal output of the USB Con is Logic "1", the signal is output to the Control IC and the Charge IC respectively, so that the first sub-signal and the second sub-signal are changed from original Logic "1" to Logic "0", the other is Logic "1", or are both Logic "0", no matter which group of Logic values the first sub-signal and the second sub-signal take at this time, after the nand Logic operation of the Logic Circuit, the Logic value "1" is input to the gate electrode of the Mosfet tube from the Logic Circuit, the gate electrode of the Mosfet tube is pulled high, the Mosfet tube is in a conducting state, and the system Circuit is switched from the off state to the working state. All circuits can be in normal working state and execute corresponding task processing. The above scheme may be implemented as a specific implementation of the second exit method described above.
The four groups of values of the first sub-signal and the second sub-signal can be seen to ensure the stability of the power supply path (the path from the battery to the system circuit) of the system because the logic condition that the switch circuit is conducted is far greater than the logic condition that the switch circuit is closed. In fig. 5, the power supply path is a supply path of battery power; the Control Signal (Control Signal) path is a logic processing path of the present embodiment.
It can be seen that the implementation of the additional Mosfet tube is realized: when the switch circuit is in a closed state, the path from the battery circuit to the system circuit is blocked by the switch circuit, so that the electricity quantity in a shift mode is successfully prevented from flowing into the system circuit end; when the switch circuit is in a conducting state, the path from the battery circuit to the system circuit is not blocked by the switch circuit, the battery circuit can normally supply power to the system circuit, and the system circuit is in a normal working state. The switch circuit in the scheme can realize the switching off of the path of the battery flowing to the system circuit, can realize the normal operation of the system circuit, and can not influence the normal operation of the equipment.
