Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 3, an embodiment of the present application provides a power failure processing method, which is described by taking an example that the method is applied to a target device, where the target device may specifically be an intelligent gateway, a routing device with an agent capability, and the like in the intelligent home system. As will be described in detail with respect to the flow shown in fig. 3, the power down processing method may specifically include the following steps:
s1, acquiring the power supply state of the power supply of the target equipment;
the target device refers to a device having a communication function, and may specifically be a device having a data forwarding function. For example, the target device may include a gateway device, a router device, and the like. Specifically, the target device represents a current device that executes the power down processing method.
It is understood that the target device includes a power supply and a first energy consuming module. The power supply means a device that converts energy in other forms into electric energy and supplies the electric energy to a target device. The power supply may be a battery power supply, an ac power supply, or the like, which is not limited in this application.
The power supply state refers to a state that the target equipment obtains required electric energy; wherein the power supply state comprises a normal state and an abnormal state; the normal state indicates that the power supply electric energy meets a preset condition, or the power supply can meet the required electric energy of the target device in the power supply process, and the like. The abnormal state indicates that the power supply electric energy does not meet the preset condition, or the power supply does not meet the required electric energy of the target device in the power supply process, and the like.
The first energy consumption module refers to a device that needs to consume a power supply to execute a corresponding function in the operation process of the target device, and may specifically be a device in the target device for executing a main function. For example, the first energy consuming module may be a master control module, a controller, a processor, etc. of the target device.
The power supply is used for supplying power to the first energy consumption module of the target device when the power supply state is normal. The target equipment can acquire the power supply state of the power supply of the target equipment in real time in the running process.
And S2, when the power supply state is abnormal, controlling the power supply to suspend supplying power to the first energy consumption module, and controlling the energy storage module of the target device to supply power to the second energy consumption module of the target device.
The target device further comprises an energy storage module and a second energy consumption module. It is understood that the energy storage module refers to a module capable of storing electric energy in the target device, and may specifically be a module capable of providing electric energy when the power supply source is powered off. For example, the energy storage module may be an energy storage capacitor capable of storing electrical energy.
The second energy consumption module refers to a module capable of performing external communication in the target device, and may specifically be a module with low power consumption and communication capability, for example, may specifically be a low power consumption controller, a zigbee module, or the like.
When the target device detects that the power supply state is abnormal, because the energy consumption of the first energy consumption module is relatively large, the power supply is controlled to pause to supply power to the first energy consumption module, and the energy storage module of the target device is controlled to supply power to the second energy consumption module of the target device, so that the target device can continue to operate for a period of time.
And S3, under the condition that the energy storage module supplies power to the second energy consumption module, controlling the second energy consumption module to broadcast and early warn to other devices in the same network system so as to indicate at least one other device in the same network system to replace the target device for forwarding proxy.
The target device may include a boost circuit and a comparison circuit, the boost circuit is disposed between the energy storage module and the second energy consumption module, the comparison circuit is disposed between the power supply and the first energy consumption module, and the comparison circuit is connected to the boost circuit.
In one embodiment, the step of obtaining the power supply state of the power supply of the target device specifically includes: acquiring a reference voltage; comparing the voltage of the power supply with the reference voltage to obtain a comparison result; and determining the power supply state of the power supply according to the comparison result.
The reference voltage is a reference source for detecting whether the power supply is normal or not by the target device, i.e. a reference, and is used for comparing whether the current power supply is in an abnormal state or not.
And in the normal working process of the target equipment, the state change of the power supply is monitored in real time through the comparison circuit. Specifically, the reference voltage can be provided by the booster circuit, and the comparison result is obtained by comparing the reference voltage with the voltage of the power supply through the comparison circuit, so as to determine the current power supply state of the power supply according to the comparison result.
In one embodiment, the power-down processing method further includes: when the power supply state is normal, the power supply supplies power to the first energy consumption module through the voltage reduction circuit;
when the power supply state is abnormal, controlling the power supply to suspend supplying power to the first energy consumption module and controlling the energy storage module of the target equipment to supply power to the second energy consumption module of the target equipment, wherein the steps comprise: and when the power supply state is abnormal, controlling the power supply to suspend supplying power to the first energy consumption module, and controlling the energy storage module of the target equipment to supply power to the second energy consumption module of the target equipment through the booster circuit of the target equipment.
The target device can further comprise a voltage reduction circuit, the voltage reduction circuit is arranged between the power supply and the first energy consumption module, and the voltage reduction circuit can be used for supplying power when the target device operates normally.
When the power supply state is normal, the power supply supplies power to the first energy consumption module through the voltage reduction circuit. When the power supply state is abnormal, the energy storage module supplies power to the second energy consumption module of the target device through the booster circuit and does not supply power to the first energy consumption module. Therefore, the energy consumption of the energy storage module can be saved, and sufficient power supply time can be provided for the second energy consumption module to finish broadcasting early warning to other devices in the same network system so as to indicate at least one other device in the same network system to replace the target device for forwarding proxy.
In a specific embodiment, the power failure processing method may be applied to a target device in an intelligent control system, for example, may be applied to an intelligent home system, and the target device may specifically be an intelligent gateway and the like. When being applied to the intelligent gateway among the intelligent home systems, even when the power supply state of intelligent gateway is in abnormal state, still can effectively make and intelligent gateway be in other equipment among the same intelligent home systems can learn the power failure state of intelligent gateway to other equipment in time deal with, take corresponding remedial measure, thereby improve intelligent home systems's stability and reliability, make intelligent home systems more intelligent, show promotion user experience.
In one embodiment, the power-down processing method further includes: when the power supply state is abnormal, outputting a first signal to a booster circuit of the target equipment through a comparison circuit;
the step of controlling the second energy consumption module to broadcast and early-warning to other devices in the same network system comprises the following steps: and controlling the second energy consumption module to broadcast and early warn to other devices under the same network system according to the first signal.
When the power supply state is abnormal, specifically, a first signal is output to the booster circuit by the comparison circuit of the target apparatus. The first signal may specifically be a prompt signal indicating that the power supply state is abnormal, and may specifically be low-voltage information, for example. The target device may then control the power supply to suspend supplying power to the first energy consuming module. And the booster circuit instructs the energy storage module of the target device to supply power to the second energy consumption module of the target device according to the first signal. After the energy storage module supplies power to the second energy consumption module, the target device controls the second energy consumption module to broadcast and early warn to other devices in the same network system.
Further, the power-down processing method further includes: when the power supply state is abnormal, outputting a second signal to the first energy consumption module through a comparison circuit of the target equipment; and after the first energy consumption module receives the second signal, storing the data generated by the target equipment.
The second signal may be a signal for alerting the target device to perform data storage. When the power supply state is abnormal, the target device may be about to be powered off, and at this time, the comparison circuit outputs a second signal to the first energy consumption module to instruct the first energy consumption module to store the data generated by the target device, so as to prevent data loss.
In one embodiment, after the comparison circuit of the target device outputs the first signal, the comparison circuit of the target device may also directly instruct the first energy consumption module to store the data generated by the target device according to the first signal, so as to prevent data loss.
In one embodiment, the step of controlling the second energy consumption module to broadcast the early warning to other devices in the same network system to instruct at least one other device in the same network system to replace the target device for forwarding proxy includes: controlling a second energy consumption module to broadcast power failure early warning signals to other equipment under the same network system; and determining at least one other device with proxy capability from other devices under the same network system as a proxy node corresponding to the target device, and performing information forwarding between the target device and other devices under the same network system by proxy of the proxy node.
Specifically, when the energy storage module supplies power to the second energy consumption module, the second energy consumption module can work, and the target device controls the second energy consumption module to broadcast and early warn to other devices in the same network system. Specifically, the target device sends a broadcast in the current wireless network through the second energy consumption module, where the broadcast may specifically be a message notifying the target device of the impending power failure, so as to notify each of the other devices in the current network system of the broadcast message.
After each other device receives the broadcast message sent by the target device, at least one other device with the proxy capability can be selected. For example, a proxy node mechanism may be specifically adopted, and other devices with proxy capability are selected from the other devices, and a proxy node acting as a proxy target device is made to proxy
The agent node performs information forwarding between the target device and other devices in the same network system by acting on the agent node, and can perform part of intelligent control function by acting on the target device.
In a specific application scenario, the power failure processing method can be applied to an intelligent home system, target equipment can be an intelligent gateway or routing equipment with agent capability, other equipment can be routing equipment, the first energy consumption module can be a main control module of the intelligent gateway, the second energy consumption module can be a communication module of the intelligent gateway, and the communication module includes but is not limited to modules such as ZigBee, bluetooth, WIFI, infrared and the like.
The target device is taken as an intelligent gateway, a first energy consumption module of the intelligent gateway is taken as a gateway master control, a second energy consumption module is taken as a ZigBee module, and an energy storage module is taken as an energy storage capacitor for example. The intelligent home system can comprise a plurality of devices, wherein the devices comprise an intelligent gateway to form a system for working, the devices can communicate with each other through a zigbee wireless network, and in a normal working state, the intelligent gateway not only executes the intelligent home control function of the intelligent gateway, but also always detects the state of a power supply of the intelligent gateway.
Specifically, main power consumption components of the intelligent gateway can be divided into a gateway main control part and a zigbee module, and when the intelligent gateway works normally, the intelligent gateway supplies power to the main control part and the zigbee module through a power supply and a channel corresponding to a voltage reduction circuit. The gateway master control power consumption is relatively large, and the zigbee module is a low power consumption part, so that the energy consumption is very low.
The intelligent gateway detects the abnormal condition of the power supply in real time in the normal working process; the intelligent gateway can monitor the change of the power supply through a comparison circuit of the intelligent gateway.
When the power supply abnormality is detected, a low-voltage alarm signal is sent out through the comparison circuit. The intelligent gateway stores the data of the intelligent gateway and immediately stops power supply to the gateway master control, so that energy is saved; and starting the energy storage capacitor to supply power to the zigbee module with low function. The electric energy stored by the energy storage capacitor is only supplied to a low-power consumption component, namely, the zigbee module supplies power, so that the zigbee module can still work for a period of time.
That is to say, when the circuit of normal power supply can't supply power, intelligent gateway then begins release energy through energy storage capacitor, supplies power to the zigbee module through the passageway that energy storage capacitor corresponds through boost circuit. Because the zigbee module has low power consumption, the zigbee module can continuously work for a period of time, and preparation is made for realizing an intelligent power failure detection mechanism.
At this moment, the intelligent gateway sends out a broadcast in the current wireless network through the Zigbee module, and informs other devices in the same current network of the message about the power failure of the intelligent gateway so as to inform the message about the power failure of the intelligent gateway.
After receiving the power-down message of the intelligent gateway, other devices in the current network can adopt a corresponding mechanism to ensure that the system continues to work under limited conditions. For example, a proxy node mechanism may be specifically enabled, a proxy node with a proxy function is selected from other devices, and the proxy node is made to replace part of the power-down device, for example, the proxy node is made to replace an intelligent gateway to continue to complete a network information forwarding function. For example, a routing device with a proxy function may be selected as a proxy node, which performs part of the intelligent control functions of the intelligent gateway instead of the role of the gateway.
For example, when an intelligent gateway in the intelligent home system is powered off, the detection result of the environment detector can still be forwarded through the proxy, so that the intelligent curtain or the intelligent lamp and the like can perform corresponding operations according to the detection result of the environment detector.
Therefore, in the mode, the intelligent gateway is detected to be powered off in time, remedial measures can be adopted in time, the agent node replaces the intelligent gateway to execute corresponding work, the policy operation of the system is maintained, the system is more intelligent, the stability and the reliability of the whole system are effectively improved, and the user experience can be remarkably improved.

Specifically, the electronic device may be an intelligent gateway, and may execute and implement the power failure processing method provided by the foregoing method embodiment.
As shown in fig. 6, the electronic device 400 includes a power supply 401, a comparison circuit 402, an energy storage module 403, a first energy consumption module 404 and a second energy consumption module 405,
the power supply 401 is configured to supply power to the first energy consumption module 404 of the electronic device 400 when the power supply state of the power supply 401 is normal, and suspend supplying power to the first energy consumption module 404 when the power supply state of the power supply 401 is abnormal;
the comparison circuit 402 is arranged between the power supply 401 and the second energy consumption module 405, and is configured to obtain a power supply state of the power supply 401 and output a first signal when the power supply state of the power supply 401 is abnormal;
the energy storage module 403 is configured to supply power to the second energy consumption module 405 through the boost circuit when the power supply state is abnormal;
the second energy consumption module 405 is configured to, after receiving the first signal, broadcast an early warning to each other device in the same network system to instruct at least one other device in the same network system to replace the electronic device 400 to perform forwarding proxy.
Further, the electronic device 400 further includes a voltage step-down circuit 406 and a voltage step-up circuit 407, where the voltage step-down circuit 406 is disposed between the power supply 401 and the first energy consumption module 404; wherein,
the power supply 401 is configured to supply power to the first energy consumption module 404 through the voltage reduction circuit 406 when the power supply state is normal; the voltage step-down circuit 406 may be a DC-DC voltage step-down circuit;
the boost circuit 407 is disposed between the energy storage module 403 and the second energy consumption module 405, and the boost circuit 407 is connected to the comparison circuit 402 for receiving the first signal and transmitting the first signal to the second energy consumption module 405;
the energy storage module 403 is configured to supply power to the second energy consumption module 405 of the target device through the voltage boost circuit 407 and not supply power to the first energy consumption module 404 when the power supply state is abnormal.
The electronic device 400 may be an intelligent gateway or a routing device, and the other devices may also be intelligent gateways or routing devices, the first energy consumption module 404 may be a main control module of the intelligent gateway or the routing device, and the second energy consumption module 405 may be a communication module of the intelligent gateway or the routing device. The same network system may be a local network system. The communication module includes, but is not limited to, ZigBee, bluetooth, WIFI, infrared, etc.
Further, the voltage boosting circuit 407 of the electronic device is also configured to provide a reference voltage to the comparison circuit 402, and the comparison circuit 402 compares the reference voltage with the voltage of the power supply 401 to obtain the power supply state of the power supply 401.
In a specific application example, the boost circuit 407 may be a DC-DC boost circuit, the principle of the DC-DC boost circuit 407 is that a high-frequency oscillator generates a low-frequency pulse voltage, and the low-frequency pulse voltage is rectified to obtain a direct-current voltage, the power supply 401 may be a 5V power supply, the energy storage module 403 may include a plurality of capacitors connected in parallel, and the DC-DC boost circuit is configured to boost the voltage of the 5V power supply passing through the plurality of capacitors connected in parallel, so as to provide a reference voltage for the comparison circuit 402. The comparison circuit 402 can monitor the power supply status of the 5V power supply by comparing the reference voltage with the voltage of the 5V power supply.
When the comparison circuit 402 monitors that the power supply of the 5V power supply is abnormal, a first signal such as a low voltage signal is sent to the DC-DC boost circuit, and the DC-DC boost circuit sends the first signal to the second energy consumption module 405, such as a ZigBee module. Meanwhile, under the condition that the power supply state of the 5V power supply is abnormal, namely, power failure occurs, the DC-DC boost circuit can also boost the electric energy stored in the energy storage module 403, namely, a plurality of capacitors connected in parallel, and then supply power to the second energy consumption module 405, so that the second energy consumption module 405 can work normally and send a power failure early warning signal to at least one other device, for example, a routing device, so that the routing device starts a power failure coping mechanism according to the power failure early warning signal.
The voltage dropping circuit 406 is configured to drop the 5V power supply to a working voltage required by the first energy consumption module 404 when the power supply state of the 5V power supply is normal, so as to normally supply power to the first energy consumption module 404. When the power supply state is normal, the first energy consumption module 404 may output the required operating voltage to the second energy consumption module 405.
When the first energy consumption module 404 is a main control module of the intelligent gateway and the second energy consumption module 40 is a communication module of the intelligent gateway, the energy consumption of the first energy consumption module 404 is usually much larger than that of the second energy consumption module 40, under the condition that the energy storage module 403 includes a plurality of capacitors connected in parallel, the energy storage module 403 is difficult to store enough electric energy to normally work for the electronic device 400, and due to the limitation of the device space, such as the limitation of the volume of the intelligent gateway, the capacitors with a plurality of large capacities cannot be set.
Therefore, in this embodiment, the energy storage module 403 is configured to, when the power supply state is abnormal, supply power to the second energy consumption module 405 of the target device through the boost circuit 407 without supplying power to the first energy consumption module 404, so that energy consumption of the energy storage module 403 can be saved, and sufficient power supply time can be provided for the second energy consumption module to complete broadcast early warning to each other device in the same network system, so as to instruct at least one other device in the same network system to replace the target device to perform forwarding proxy.
When the electronic device 400 is used as an intelligent gateway or a routing device and normally works, the power supply 401, such as a 5V power supply, simultaneously supplies power to the first energy consumption module 404 and the second energy consumption module 405 through the voltage reduction circuit, and the comparison circuit 402 compares the power supply voltage of the power supply 401 with the reference voltage all the time, so as to monitor the power supply state of the power supply 401.
When abnormal power failure occurs, the power supply voltage drops immediately, and the comparison circuit 402 sends a low voltage signal when finding that the power supply voltage is lower than the reference voltage. When the second energy consumption module 405 receives the low voltage signal, it indicates that the abnormal power outage has occurred, and the energy storage capacitor in the energy storage module 403 starts to release the stored electric energy to supply power to the second energy consumption module 405. Because the power consumption of the second energy consuming module 405 is relatively low, the energy stored in the energy storage capacitor of the energy storage module 403 can be used to continue to operate for a period of time. At this time, by means of the wireless broadcast function of the second energy consumption module 405, for example, the ZigBee module, the electronic device may send a broadcast to other devices, such as a routing device, in a network system where the electronic device is located by using the second energy consumption module 405, and notify other devices in the smart home system network of the message that the electronic device is about to power down.
Further, the comparing circuit 402 is further configured to output a second signal, such as a low voltage alarm signal, to the first energy consumption module 404 when the power supply state is abnormal; the first energy consumption module 404 is configured to immediately store the data generated by the electronic device 400 after receiving the second signal, stop the work task, and exit in a safe manner to prevent data loss or hardware damage caused by sudden power failure.
