Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In the correlation technique, when considering that the intelligent switch is connected with the low-power load in series, the working current of the low-power load is difficult to support the intelligent switch to normally work, and then an energy storage device is provided for the intelligent switch, and the energy is supplied to the intelligent switch through the energy storage device. Therefore, the energy storage state of the energy storage device is related to whether the intelligent switch can work normally or not.
The operation of the intelligent switch 100 is described in conjunction with fig. 1. As shown in fig. 1, the intelligent switch 100 is connected in series with a low power LED (Light Emitting Diode) lamp 110. The intelligent switch 100 controls the LED lamp 110 to be turned on or off according to the received task command. Considering that the LED lamp 110 has a small power, a small current is needed to maintain the LED lamp 110 to operate normally. In order to solve the problem that the power of the intelligent switch 100 is not enough due to the fact that the external load power is small in use, an energy storage device (for example, a capacitor) is integrated in the intelligent switch 100 and used for providing electric energy for the intelligent switch 100, and then the intelligent switch 100 can be connected with a low-power load in series and is controlled.
Fig. 2 is a schematic diagram of a possible circuit structure of the intelligent switch according to an embodiment of the present disclosure. The intelligent switch 100 is connected in series with the low-power load 110, the intelligent switch 100 comprises a processor, a single-fire power getting circuit and a power monitoring circuit, the processor is electrically connected with the power monitoring circuit and the single-fire power getting circuit, and the power monitoring circuit is electrically connected with the single-fire power getting circuit. The single live wire power supply circuit is used for supplying power to the processor, and the power supply monitoring circuit acquires the voltage of the single live wire power supply circuit, namely the voltage V of the point C in the figureC. The processor collects the real-time voltage V of the D point through the power supply monitoring circuitD. Wherein, the voltage V of point BBVoltage V at point CCThe sum is the total voltage of the whole system of the intelligent switch, and the real-time voltage VDThe following relation is satisfied with the total voltage:
VD＝1/3(VB+Vc)；
the intelligent switch obtains the real-time voltage of the point D through the processor, and the total voltage of the intelligent switch is obtained through the calculation of the voltage relation. When the electric quantity of the energy storage device is insufficient, the intelligent switch is in an undervoltage state, and the total voltage is lower than the normal working voltage.
In view of the working principle of the intelligent switch, the embodiment of the application provides a device sleeping method, which is applied to electronic devices. The electronic device may be the above-mentioned intelligent switch, and may also be an intelligent device including the intelligent switch. For example, the smart device may be a single fire panel, a single fire LED light, a smart sensor, and the like.
The electronic equipment enters a sleep mode to sleep by detecting the current real-time voltage when the real-time voltage is smaller than a preset voltage threshold. Because the power consumption of the electronic equipment in the sleep mode is less than that in the non-sleep mode, the energy storage device can be quickly filled with electric energy to maintain the normal work of the electronic equipment.
Regarding the electronic apparatus, a hardware structure thereof is exemplarily explained below with reference to fig. 3. The electronic device comprises a power storage device 250, a processor 230, a memory 220 and a communication device 240. The memory 220, processor 230, energy storage device 250, and communication device 240 are electrically connected to each other, either directly or indirectly, to enable the transfer or interaction of data.
The communication means may be a wired or wireless communication means for receiving the task instructions. For example, the processor receives a task instruction for controlling a load through the communication device.
The Memory 220 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like. The memory 220 is used for storing programs, and the processor 230 executes the programs after receiving the execution instructions. The communication device 240 is used for transmitting and receiving data through a network.
With regard to the device sleep method, the following is described in detail with reference to the flowchart of the steps of the device sleep method shown in fig. 4.
And step S101, acquiring a real-time voltage value.
The real-time voltage value represents a current power supply state of the electronic device, and may be a power supply voltage of the whole electronic device or a power supply voltage of one or more devices in the electronic device. Namely, when the real-time voltage is greater than or equal to the preset voltage threshold, the electronic equipment can work normally. When the real-time voltage is smaller than the preset voltage threshold, the electronic device may be down or automatically restarted due to undervoltage.
In a possible implementation manner provided by the embodiment of the application, it is considered that the instantaneous voltage of the electronic device may be influenced by the fluctuation of the power grid, a voltage spike occurs at a certain moment, and then the judgment result of the real-time voltage value is influenced.
Therefore, the step S101 includes:
and S101-1, acquiring the acquisition voltage of the electronic equipment in the current preset sleep cycle.
And S101-2, filtering the acquired voltage to obtain a real-time voltage value.
It should be understood that there are many methods for filtering the voltage, and the average filtering algorithm is taken as an example to illustrate the above steps.
The electronic equipment collects voltage once every 20ms within 100ms, 5 collected voltages collected within 100ms are calculated averagely, and the obtained average value is used as the real-time voltage value. Therefore, misjudgment caused by voltage spikes can be avoided.
Step S102, judging whether the real-time voltage value is smaller than a preset voltage threshold value.
When the real-time voltage of the electronic equipment is greater than or equal to the preset voltage threshold, the electronic equipment can normally work. For example, the electronic device may be capable of task scheduling and execution of device task instructions.
Step S103, if the real-time voltage value is smaller than the preset voltage threshold, entering a sleep mode for sleeping for a first sleep period.
The electronic equipment compares the current real-time voltage value with a preset voltage threshold, and enters a sleep mode to sleep when the real-time voltage value is not enough to normally maintain the electronic equipment to work so as to prevent the electronic equipment from working in an undervoltage state.
In the embodiment of the application, it is considered that the length of the first sleep cycle may affect the response efficiency of the electronic device to the task instruction. It should be understood that, in the sleep mode with a fixed sleep cycle, the electronic device needs to sleep for the same sleep cycle no matter how much power is left in the electronic device, so that the electronic device has a problem of poor efficiency when responding to a task instruction. For example, when the fixed sleep cycle is 300ms, the remaining power of the electronic device is 50%, or 90% of the electronic device needs to sleep for 300 ms. However, compared to the sleep period required by 50% of the remaining power, 90% of the remaining power requires relatively less sleep period to fully store the energy storage device of the electronic device.
Therefore, in one possible implementation manner provided by the embodiment of the present application, the step S103 includes:
and step S103-1, acquiring the number of times of undervoltage.
The undervoltage times represent the undervoltage times of the electronic equipment, and when the real-time voltage value is greater than or equal to a preset voltage threshold, the undervoltage times are cleared; otherwise, the undervoltage times are accumulated and updated.
For example, if the historical undervoltage number is 3 after the electronic device wakes up from the sleep mode, it indicates that the electronic device is in the undervoltage state after 3 times of waking up from the sleep mode.
If the current real-time voltage value of the electronic equipment is smaller than the preset voltage threshold value, accumulating and updating the voltage value 3 to obtain the updated under-voltage frequency of 4.
If the current real-time voltage value of the electronic equipment is greater than or equal to the preset voltage threshold value, clearing the voltage value 3, and then updating the undervoltage frequency to be 0.
Optionally, as a possible implementation, the electronic device may wake up from the sleep mode by a wake-up signal. The wake-up signal may be a timer interrupt signal generated by a timer. That is, the timer generates an interrupt signal after the timing is finished, and the electronic device wakes up the electronic device from the sleep mode after capturing the interrupt signal.
And step S103-2, determining a first sleep cycle according to the undervoltage times.
The undervoltage times can reflect the current energy storage state of the electronic equipment to a certain extent. For example, when the number of times of under-voltage is large, it indicates that the electronic device is still in an under-voltage state after the electronic device passes through a plurality of consecutive sleep modes. Therefore, the condition that the residual electric quantity in the energy storage device of the electronic equipment is less and more sleep cycles are needed for energy storage can be reflected.
In view of this, in an implementation manner provided by the embodiment of the present application, the first sleep cycle is positively correlated to the brown-out times.
It should be noted that there are many cases in the positive correlation between the first sleep cycle and the under-voltage frequency, including a linear positive correlation and a non-linear positive correlation. The following is an exemplary description of a linear positive correlation and a non-linear correlation.
Let the updated under-voltage number be N, and if the updated under-voltage number is a linear positive correlation, the first sleep cycle may be represented as 2 × N. If there is a non-linear positive correlation, the first sleep cycle can be represented as 2N. 2 in the above example is the sleep cycle adjustment cardinality, which is adapted by those skilled in the art based on the needs.
It is obvious that for the above-mentioned positive correlation specific implementation, those skilled in the art can make an adaptive selection based on actual needs, which do not need to make creative contributions based on the technical solutions disclosed in the present application.
And step S103-3, executing a sleep instruction, and entering a sleep mode to sleep for a first sleep period.
Therefore, after the electronic device is awakened from the sleep mode each time, the undervoltage times are updated, and the first sleep cycle is dynamically adjusted according to the updated undervoltage times. Because the first sleep cycle determined by the electronic equipment is positively correlated with the under-voltage times, the electronic equipment can sleep for a longer sleep cycle when the under-voltage times are more. And because the number of times of undervoltage represents the electric quantity situation of the electronic equipment, therefore, the purpose of adjusting the charging sleep cycle based on the electric quantity situation can be achieved, and when the residual electric quantity of the electronic equipment is more, the electric quantity in the energy storage device can be fully stored only by sleeping in the sleep mode for a shorter sleep cycle.
Therefore, the electronic equipment dynamically adjusts the first sleep cycle through the undervoltage times, so that the electronic equipment can obtain sufficient electric quantity and improve the response efficiency of the task instruction.
In addition, referring to fig. 4 again, the sleep method of the device provided in the embodiment of the present application further includes:
and step S104, if the real-time voltage value is greater than or equal to the preset voltage threshold, entering a sleep mode for sleeping for a third sleep period.
For clarity, the intelligent switch of one of the electronic devices is taken as an example and is explained in detail below.
The preset voltage threshold of the intelligent switch is set to be 3.3V, and a formula 150 × N is assumed to determine a first sleep cycle, wherein a unit is milliseconds (ms), N represents the number of times of undervoltage, 150 is a sleep base number, and adaptive adjustment can be performed according to actual requirements. The intelligent switch is awakened from the sleep mode for the 10 th time, and the historical undervoltage times are 3. The undervoltage times represent that the real-time voltage values of the intelligent switch are all smaller than 3.3V after the intelligent switch is awakened from the sleep mode for the 9 th time, the 8 th time and the 7 th time.
In a possible case, after the intelligent switch is awakened from the sleep mode for the 10 th time, the current real-time voltage value is acquired to be less than 3.3V. The intelligent switch is accumulated on the basis of 3, and the updated undervoltage frequency is 4. Based on the updated number of undervoltages, the smart switch calculates the first sleep period to be 600 ms by equation 150 x N.
In another possible case, after the intelligent switch is awakened, the current real-time voltage is greater than or equal to 3.3V. Therefore, the intelligent switch clears the undervoltage times, and determines the initial value of the first sleep cycle to be 250 milliseconds based on the cleared undervoltage times, wherein the 250 milliseconds can be adaptively adjusted according to actual requirements.
And because the electronic equipment wakes up from the sleep mode for the 10 th time, the undervoltage times are cleared, if the electronic equipment wakes up from the sleep mode for the 11 th time and the power supply voltage of the electronic equipment is less than 3.3V, the undervoltage times are accumulated again, namely the electronic equipment wakes up from the sleep mode for the 11 th time, and the updated undervoltage times are 1.
In addition, in the embodiment of the present application, the task instructions executed by the electronic device are divided into two types, which are a high power consumption instruction and a low power consumption instruction respectively. For example, the operation corresponding to the high power consumption instruction may be an operation related to network connection. The low power consumption instruction may correspond to an operation for controlling the load to be turned on and off. The high power consumption instructions are classified into a first category and a second category. The first category may be network entry instructions; the second category may be re-network instructions.
It should be noted that the electronic device needs to be communicatively connected to the gateway, so that the user can send task instructions to the electronic device through the gateway.
Therefore, before step S103, the electronic device receives a task instruction; and judging the category of the task instruction.
The task instruction is a task instruction currently executed by the electronic device. Due to the different power consumption requirements of different task instructions, the different task instructions need to be processed in a targeted manner.
If the task command belongs to the first category, the electronic device shuts down a load electrically connected with the electronic device.
If the task instruction belongs to the second category, the electronic device postpones execution until the real-time voltage is greater than or equal to the preset voltage threshold. And the voltage required for executing the first category of task instructions is greater than the voltage required for executing the second category of task instructions.
For different electronic devices, the high power consumption instruction has a certain difference. The above steps are exemplified by a zigbee (zigbee) protocol based intelligent switch. In the intelligent switch based on the zigbee protocol, the first class of instructions may be network access operation instructions based on the zigbee protocol, and the second class of instructions may be re-network instructions based on the zigbee protocol.
It should be understood that the operation corresponding to the network access operation instruction is a network protocol related operation required when the intelligent switch first joins the zigbee networking. The operation corresponding to the network re-entry instruction is the operation required by the intelligent switch to establish communication connection with the gateway again after the gateway in the zigbee networking is abnormally restarted. Both of the above operations require increased power consumption to search for the zigbee signal in space, and therefore, more energy is required to sustain the above operations. In view of the fact that a large amount of network interaction is required for network access operation, and then more energy is required, in the embodiment of the present application, the load controlled by the electronic device is turned off to further reduce power consumption.
It is worth mentioning that in the network architecture of the zigbee protocol, the gateway is used for forwarding and buffering messages. And after the intelligent switch is awakened from the sleep mode, the communication connection is established on the gateway based on the zigbee protocol. And once the gateway finds that the intelligent switch is connected into the network, the gateway sends the task instruction cached in the sleep mode of the intelligent switch to the intelligent switch. Of course, the task instruction can also be obtained based on the state of the intelligent switch itself. For example, the intelligent switch detects that a network access operation or a network re-access operation needs to be executed currently based on the network state.
Additionally, it is contemplated that the proper operation of the electronic device is dependent upon the amount of power in the energy storage device 250. Therefore, in this embodiment of the present application, the device sleep method further includes:
when the electronic equipment is started for the first time, the electronic equipment is controlled to enter a sleep mode to sleep for a second sleep period. Alternatively, the second sleep period may be 1 s.
Because the electronic device is powered on for the first time, the energy storage device in the electronic device is in a dry state, and therefore, sufficient time is ensured for the energy storage device 250 of the electronic device to be fully charged through the second sleep cycle of the electronic device, so that the electronic device can normally work after being awakened from the sleep mode.
The following also takes the intelligent switch as an example, and provides a possible implementation manner for the device sleep method described above with reference to fig. 5, and the device sleep method is described in detail. Wherein, the preset voltage threshold of the intelligent switch is 3.3V.
When the intelligent switch is powered on and started, the intelligent switch is forced to enter a sleep mode for 1 s. After the intelligent switch sleeps for 1s, the intelligent switch is awakened from the sleep mode in response to an awakening signal, and initialization operation after power-on is carried out.
The initialization operation includes an initialization operation for each device in the intelligent switch and a parameter-dependent initialization operation. For example, the brownout times may be initialized to zero by a parameter initialization operation.
Further, the intelligent switch initializes the power supply voltage monitoring task. And the intelligent switch executes some basic instructions while initializing the power supply voltage monitoring task. The operation corresponding to the basic instruction may include an indicator light display state control operation, an apparatus temperature monitoring operation, and an apparatus key monitoring operation.
The intelligent switch acquires a current real-time voltage value based on the initialized power supply voltage monitoring task and judges whether the real-time voltage value is smaller than 3.3V or not.
If the voltage is greater than or equal to 3.3V, the intelligent switch clears the undervoltage times and executes some received control instructions, such as opening or closing the load; after the execution, the sleep mode is entered to sleep for 250 ms.
If the current task instruction is less than 3.3V, the intelligent switch judges whether the current task instruction is a network access operation instruction or a network re-access operation instruction.
If the network access operation instruction is received, the intelligent switch closes the load so as to further reduce the power consumption of the equipment. Meanwhile, after the intelligent switch executes some initialization operations related to network operations (for example, initializing a zigbee chip), the intelligent switch enters a sleep mode to sleep until the energy storage device is full of electric quantity, and then executes a network access operation instruction.
If the network re-entry operation instruction is the network re-entry operation instruction, the intelligent switch also executes some initialization operations related to network operation, and then postpones the execution of the network re-entry operation instruction until the real-time voltage value is larger than or equal to the preset voltage threshold value.
If the current task instruction is neither a network access operation instruction nor a re-network access operation instruction, the intelligent switch stops the current running task instruction and updates the undervoltage times; and after determining the sleep period of the sleep mode based on the updated under-voltage times, entering the sleep mode for sleeping.
Based on the same inventive concept, the embodiment of the application also provides the equipment sleep device, and the equipment sleep device comprises at least one functional module which is stored in the memory in a software form. When the computer executable instruction corresponding to the equipment sleeping device is executed by the processor, the equipment sleeping method is realized. Referring to fig. 6, functionally, the device sleep apparatus 210 includes:
a voltage obtaining module 1101, configured to obtain a real-time voltage value.
In the embodiment of the present application, the voltage obtaining module 1101 is configured to execute step S101 in fig. 6, and please refer to the detailed description of step S101 for a detailed description of the voltage obtaining module 1101.
The device sleep module 1102 is configured to determine whether the real-time voltage value is smaller than a preset voltage threshold;
