In order to make the purpose, the technical solutions and the advantages of one or more embodiments of the present disclosure clearer and more understandable, embodiments of the present disclosure are further described in detail below with 10 reference to accompanying figures and embodiments. It should be understood that the specific embodiments described herein are only intended to illustrate but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention below can be combined as long as they don’t conflict with each other.

As an embodiment of the present invention, this method can be applied in the collection of light energy, wind energy, fluid energy and pressure kinetic energy, and is
2019100389 09 Apr 2019 especially suitable for management of micro-ampere level micro-energy collection with smaller electric quantity, and data statistics and remote control can be performed in combination with the internet of things or a carrier.
The power management method based on micro-energy collection is performed by the SOC which is built in a MCU (Micro Control Unit), and the method includes following steps:
In step 101, selecting a collection mode to collect micro-energy according to current power supply electric quantity and the current collected electric quantity, the collection mode at least includes a low-power-consumption collection mode and a highefificiency collection mode;
In this embodiment of the present disclosure, the SOC can be built in the MCU and is used to collect micro-energy, it is worth noting that, the SOC herein includes a universal MCU, a system built in the MCU and external components that are necessary for the chip, the SOC establishes the system on the universal MCU to enable the universal MCU to have a specific function, besides, an optimization function is much easier, and a development period is shorter.
Since the collected electric quantity is weak, a corresponding collection mode needs to be started for micro-energy collection. For example, when the current collected electric quantity is much lower, and the current electric quantity of the power supply is insufficient, a low-power-consumption collection mode with lower power consumption is used for collection; and when the current collected electric quantity is higher, a highefficiency collection mode with higher collection efficiency can be selected, so that an accumulation of electric quantity can be performed more quickly.
The low-power-consumption collection mode works in a working mode in which the MCU is slept, and an awakening frequency is set by controlling the number and the width of collected boost pulses;
the high-efficiency collection mode may use MPPT (Maximum Power Point Tracking) to control collection, select an optimal parameter and an optimal power 5
2019100389 09 Apr 2019 consumption balance voltage point through the MPPT, and collect the micro-energy according to the optimal parameter and the optimal power consumption balance voltage point.
As a preferable embodiment of the present disclosure, in the step 101, the current power supply electric quantity can be determined by detecting the current power supply voltage, the current collected electric quantity can be determined by detecting an input current, an input voltage or an input charge.
For example, the current collection mode can be determined by a table look-up according to the voltage in the current electric energy storage unit, a detection 10 frequency can be reduced if the current electric quantity is low, in other words, the collection mode is not changed frequently, so that the power consumption is reduced.
If the current electric quantity is high, the detection frequency can be increased, that is, collection modes which are more suitable for the current environment are continuously replaced, so that collection efficiency is improved.
In step 102, setting a communication threshold value and a load threshold value;
In step 103, determining whether the current power supply electric quantity is greater than the communication threshold value regularly according to a time stamp, and communicating with a server when the current electric quantity of the power supply is greater than the communication threshold value;
In the embodiment of the present disclosure, the current power supply electric quantity can be determined at regular time according to the time stamp, the current power supply electric quantity can also be determined at regular time according to a preset frequency, communication is performed with the server and a data interaction is performed when the current electric quantity meets a communication condition; the data interaction includes uploading collected data to the server, identifying an update instruction on the server, sending an update request to the server and downloading the update data from the server so as to reconfigure a collection standard according to acquired update data.
2019100389 09 Apr 2019
Of course, regarding the time stamp, before an agreement between two parties is made, for example, when the communication is performed for the first time, the communication can be performed according to default time stamp.
In step 104, determining whether the current power supply quantity is greater than the load threshold value or not at regular time, and supplying electric power to the load in the event that the current electric quantity of power supply is greater than the load threshold value.
In the embodiment of the present disclosure, the power supplying priority is sequentially as follows: collection, communication, and power supplying of the load. Power is supplied for communication when the current electric quantity meets the power consumption of collection task, and supplied power is output to load only when the current electric quantity meets the power consumption requirement of communication, either. When the current electric quantity is not sufficient to meet the power consumption requirement of current communication, the communication can be delayed by prolonging the time stamp or reducing the frequency of communication.
Preferably, in step 103, whether the current power supply electric quantity is lower than a preset communication lower limit threshold value is further determined when communicating with the server, where the communication lower limit threshold value is lower than the communication threshold value;
the communication is interrupted if the current power supply electric quantity is lower than the preset communication lower limit threshold value, and the breakpoint data is recorded, so that data can be continuously transmitted according to the breakpoint data when the communication is performed again;
the communication is kept if the current power supply electric quantity is equal to or greater than the preset communication lower limit threshold value.
In the embodiment of the present disclosure, in the event that the electric quantity of the power supply suddenly drops below a preset value in the communication process, the current communication requirement cannot be ensured, the communication is 7
2019100389 09 Apr 2019 interrupted, and the breakpoint data is stored; data interaction is continued to be completed according to the breakpoint data when the electric quantity is restored to be greater than the preset value.
According to the embodiment of the present disclosure, a power management system is built in the SOC based on the existing IC, and the power consumption is further reduced by setting a power supplying priority, which is suitable for constraint of power supplying of micro-energy collection, a power management of microampere level power consumption is achieved, the application range of energy collection is broadened, an environmental constraint of energy collection is broken through, and an application field of clean energy is expanded.
FIG. 2 illustrates a flow structural diagram of step 101 in the power management method based on micro-energy collection according to the embodiment of the present disclosure, for convenience of description, the part related to the present disclosure is merely illustrated.
The specific steps of selecting a collection mode to collect micro-energy collection according to the current power supply electric quantity and the current collected electric quantity in step 101 are as follows:

executing step 202 of selecting a high-efficiency collection mode, if the current collected electric quantity is greater than the first collection threshold value;

executing step 204 of selecting a low-power-consumption collection mode, if the current electric quantity is lower than or equal to the second collection threshold value.

executing step 206 of entering a sleep state with only the low-power-consumption collection mode being maintained, if the current electric quantity of power supply doesn’t continuously exceed the second collection threshold value in the preset time period or at multiple time interval points;
executing step 207 of switching from the sleep state to an awaken state with the high-efficiency collection mode is selected being selected, if the current electric quantity of power supply continuously exceeds the second collection threshold value in the preset time period or at multiple time interval points.
In the embodiment of the present disclosure, when the current electric quantity floats up and down at an unstable critical value (i.e., the second collection threshold value), more power can be consumed if the collection state is frequently switched, therefore, the sleep state can be temporarily started at this moment, and the low-power9
2019100389 09 Apr 2019 consumption collection mode is kept, so that micro-energy is continuously collected until the electric quantity of the power supply is greatly increased, and the electric quantity of the power supply no longer floats up and down at the vicinity of the critical value, the system is awaken and enters the high-efficiency collection mode, because that there are much electric quantities at this moment, it is possible to perform the collection by switching to a collection mode with higher collection efficiency.
