As shown in fig. 1 and 2, a first embodiment of the present application provides an in-situ energy harvesting and information processing system, which includes a sensor 11, a first processing unit 21, an internal source energy management unit 31, and a first control unit 41.

The sensor 11 is used for collecting energy and information input into the system, converting the energy into electric energy, transmitting the electric energy to the internal source energy management unit 31, and transmitting the information to the first processing unit 21. The endogenous energy management unit 31 is used to receive and store electrical energy from the sensor 11 and to detect the output power of the sensor 11. The first control unit 41 is used to turn on the first processing unit 21 and to control the sensor 11 to transmit information to the first processing unit 21. The first processing unit 21 is configured to receive and process the information collected by the sensor 11, and determine whether the processed information satisfies a predetermined condition. The endogenous energy management unit 31 is also used to power the sensor 11, the first control unit 41 and the first processing unit 21.

In some embodiments of the present application, the energy input into the system may be light energy, wind energy, acoustic energy, etc., and different types of sensors 11 may be used to collect different energy. In the present application, the sensor 11 comprises several subunits. For example, for an image sensor with a resolution of one million, which is made up of a 1000 x 1000 array of pixels, a single pixel may be referred to as a sub-unit. For a single microphone transducer, it contains only one subunit that converts the acoustic vibration signal into an electrical signal.

It should be noted that each subunit has functions of Energy Harvesting (EH-Energy Harvesting) and Information Harvesting (IS-Information Sensing), and can switch between the two functions according to actual needs. In this application, in situ means that both energy and information acquisition is performed within the sensor 11.

In particular, when there is only one subunit in the sensor 11, the functionality of that subunit may be configured in a time-multiplexed manner. In one time period, the subunit performs energy acquisition, and in another time period, the subunit performs information acquisition. For example, the subunit performs only information acquisition for the first 100ms and only energy acquisition for the last 900ms within 1 s. By adopting the time division multiplexing mode, the time utilization efficiency of the sensor 11 can be improved.

When a plurality of subunits are included in the sensor 11, the functions of the plurality of subunits may be configured according to a space division multiplexing manner. For example, all subunits are configured for energy harvesting function; or all the subunits are configured to have an information acquisition function; or a part of the subunits are configured to be energy collecting functions, and the other part of the subunits are configured to be information collecting functions. The space utilization efficiency of the sensor 11 can be improved by adopting the space division multiplexing mode.

It should be noted that when all the subunits are configured to be energy harvesting function, the sensor 11 only harvests energy input into the system, specifically, harvests energy input into the plane of the sensor 11. When all subunits are configured as an information gathering function, the sensor 11 only gathers information input into the system, in particular into the plane of the sensor 11. When a portion of the sub-units are configured for energy harvesting functionality and another portion of the sub-units are configured for information harvesting functionality, the sensor 11 harvests energy and information input into the system, specifically into the plane of the sensor 11.

It should be noted that a plurality of sub-units can be arranged in an array. The number and location of subunits configured as energy harvesting and information harvesting functions may be arranged according to actual requirements. In the application, a plurality of subunits are integrated in one array and arranged according to actual needs, and the size of the sensor is favorably reduced while the function of each subunit is flexibly applied, so that the size of the whole system is favorably reduced, and the manufacturing cost is reduced.

In the present application, the sensor 11 may be understood as being configured according to different operating modes of the system. The working mode of the system can be preset into a starting mode, a normally open mode and a triggering mode. Take the example that the sensor 11 includes a plurality of subunits; when the system is in a start-up mode, all subunits in the sensor 11 are configured to function for energy harvesting, and all subunits spontaneously perform energy harvesting in situ; when the system is in a normally open mode, one part of subunits in the sensor 11 is configured to be an energy collection function, and the other part of subunits is configured to be an information collection function, and the subunits configured to be the energy collection function spontaneously collect energy in situ; when the system is in the trigger mode, all subunits in the sensor 11 are configured as information gathering functions.

In some specific embodiments of the present application, the internal source energy management unit 31 includes an internal source auxiliary circuit 311, a cold start circuit 312, an MPPT circuit 313 (maximum power point tracking circuit), and an internal source conversion circuit 314.

Wherein, when a part of the subunits in the sensor 11 are configured to energy collecting function and another part of the subunits are configured to information collecting function; the cold start circuit 312 is used for receiving and storing electric energy from the sensor 11, specifically, electric energy from a sub-unit configured as an energy collection function in the sensor 11; when the power stored by the cold start circuit 312 reaches a certain threshold, the cold start circuit 312 triggers the start of the internal source auxiliary circuit 311, the MPPT circuit 313, and the internal source conversion circuit 314. The internal source auxiliary circuit 311 provides peripheral signals, such as clock signals, sampling signals, reference voltage signals, etc., required for operation to the MPPT circuit 313 and the internal source conversion circuit 314 after normal startup. The MPPT circuit 313 detects the output power of the sensor 11 after the normal start. The internal source conversion circuit 314 converts the electric power from the sensor 11 after normal start-up, and outputs a stable direct-current voltage to power the first control unit 41 and the first processing unit 21, and to power the sub-units configured as the information acquisition function in the sensor 11.

In the present application, the MPPT circuit 313 can also maximize the output power of the sensor 11 by adjusting the load of the energy collection bus after the normal start. Specifically, the MPPT circuit 313 maximizes the output power of the sensor 11 by adjusting the operating parameters of the internal source converter circuit 314, such as adjusting the clock frequency, clock duty ratio, and the like of the operation of the internal source converter circuit 314.

In the present application, the endogenous conversion circuit 314 may be a DC-DC/AC-DC converter. When the internal source auxiliary circuit 311, the MPPT circuit 313 and the internal source conversion circuit 314 are normally started, the sensor 11 provides an operating voltage.

It should be noted that, according to the different types of sensors 11 selected, the sensors 11 may output direct current or alternating current; when the sensor 11 outputs dc power, the internal source auxiliary circuit 311, the cold start circuit 312, the MPPT circuit 313, and the internal source conversion circuit 314 are all directly supplied with operating voltage from the sensor 11. When the sensor 11 outputs ac power, the internal auxiliary circuit 311, the cold start circuit 312, the MPPT circuit 313, and the internal source conversion circuit 314 may each have a built-in rectifier, and the ac power output by the sensor 11 is converted into dc power by the built-in rectifier to provide operating voltages for the internal auxiliary circuit 311, the cold start circuit 312, the MPPT circuit 313, and the internal source conversion circuit 314.

In some embodiments of the present application, after the first control unit 41 is powered, the functions of the sub-units in the sensor 11 may be configured in advance according to actual needs, and the sub-units are brought into corresponding functional states.

In this application, the first control unit 41 may be understood as pre-configuring the functions of the sub-units in the sensor 11 according to different operation modes of the system, and the configuration manner is consistent with the above, and is not described herein again.

In the present application, the first control unit 41 has two power supply ports, one being a power supply port powered by the endogenous energy management unit 31 and the other being a power supply port powered by an external power source. The first control unit 41 may be understood to invoke different power supply ports depending on the different operating modes of the system. That is, the first control unit 41 may be selectively powered by the internal source energy management unit 31 or an external power source. When the system is in a normally open mode, the internal source energy management unit 31 is adopted to supply power to drive the first control unit 41; when the system is in the start mode and the trigger mode, the first control unit 41 is powered by an external power source.

In some embodiments of the present application, the first processing unit 21 may be used to process the information collected from the sensor 11 after the first processing unit 21 is turned on by the first control unit 41. Specifically, when a part of the subunits in the sensor 11 are configured as the information acquisition function, the information acquired by the subunits configured as the information acquisition function is transmitted to the first processing unit 21; after receiving the information, the first processing unit 21 runs a corresponding algorithm to extract the relevant information in the surrounding environment from the received information, and determines whether the extracted relevant information satisfies a predetermined criterion.

In some embodiments of the present application, the in-situ energy harvesting and information processing system further comprises an external source energy management unit 32, the external source energy management unit 32 being configured to convert an external power source, on the one hand, and to receive and store a portion of the electrical energy from the internal source energy management unit 31, on the other hand. It should be noted that the first control unit 41 is a power supply port powered by an external power source, specifically, a power supply port powered by an external power source through the external source energy management unit 32.

Specifically, the external source energy management unit 32 includes a charging circuit 321, an external source auxiliary circuit 322, and an external source switching circuit 323.

When the charging circuit 321 is triggered to be turned on, the charging circuit 321 receives and stores a part of the electric energy from the internal source energy management unit 31, and charges the external power source with the part of the electric energy. After the external source conversion circuit 323 is triggered to be turned on, the external source conversion circuit 323 converts an external power source to output a stable dc operating voltage. The external source auxiliary circuit 322 is used to provide peripheral signals, such as a clock signal, a sampling signal, a reference voltage signal, etc., necessary for the operation of the charging circuit 321 and the external source conversion circuit 323.

In the present application, the external power source may be a direct current power source, and the external source conversion circuit 323 may be a DC-DC converter. The voltage output by the external power supply is converted into a direct current voltage required by the operation of part of units in the system through an external source conversion circuit 323. The external auxiliary circuit 322, the triggered charging circuit 321 and the external switching circuit 323 are all directly supplied with operating voltage by the external power supply.

In other embodiments, the external power source may also be an alternating current power source, and the external source conversion circuit 323 may be an AC-DC converter. The charging circuit 321 and the external auxiliary circuit 322 may both have built-in rectifiers, and the built-in rectifiers convert ac output by the external power supply into dc to provide operating voltage for the charging circuit 321 and the external auxiliary circuit 322.

In some embodiments of the present application, the in-situ energy harvesting and information processing system further comprises a second processing unit 22, wherein the second processing unit 22 can be configured to process the information harvested from the sensor 11 after the second processing unit 22 is turned on by the first control unit 41. Specifically, when all the subunits in the sensor 11 are configured to have the information collecting function, the information collected by all the subunits is transmitted to the second processing unit 22; after receiving the information, the second processing unit 22 runs a corresponding algorithm to process the information.

In some embodiments of the present application, the in-situ energy harvesting and information processing system further includes a second control unit 42, and the second control unit 42 may be configured to pre-configure the working mode of the system and send corresponding working mode signals to the first control unit 41 and the external source energy management unit 32; and for switching the operating mode of the system.

In the present application, the second control unit 42 configures the operation mode of the system to the start mode, the normally open mode, and the trigger mode in advance; after the second control unit 42 sends the corresponding working mode signal to the first control unit 41, the first control unit 41 configures the functions of the sub-units in the sensor 11 according to different working modes; and invokes the first processing unit 21 or the second processing unit 22 according to the different operating modes. After the second control unit 42 sends the corresponding operating mode signal to the external source energy management unit 32, the external source energy management unit 32 adjusts the operating states of the charging circuit 321 and the external source switching circuit 323 according to different operating modes. The second control unit 42 may also switch the operating mode of the system according to the start signal sent by the internal source energy management unit 31, the interrupt signal sent by the first processing unit 21, or the interrupt signal sent by the second processing unit 22.

According to the in-situ energy collection and information processing system provided by the embodiment of the first aspect of the present application, when the sensor 11 includes a plurality of sub-units and the system is in different operation modes, the system has the following working flow.

When the system is in the start-up mode, the external source switching circuit 323 is turned on, and the charging circuit 321 is turned off. As shown in fig. 3, the first control unit 41 is powered by an external power source through an external source switching circuit 323; the first control unit 41 configures all subunits in the sensor 11 to be energy collection function; the sensor 11 spontaneously collects energy, converts the collected energy into electric energy, and transmits the electric energy to the cold start circuit 312 in the internal source energy management unit 31 through the energy collection bus; the second control unit 42 is powered and driven by an external power supply through an external source conversion circuit 323; the cold start circuit 312 receives and stores the electric energy from the sensor 11; when the electric energy reaches a certain threshold (i.e. the voltage of the cold start circuit 312 reaches a predetermined voltage value), the cold start circuit 312 triggers to start the internal source auxiliary circuit 311, the MPPT circuit 313 and the internal source conversion circuit 314; when the internal source auxiliary circuit 311, the MPPT circuit 313 and the internal source conversion circuit 314 are all normally started, the cold start circuit 312 generates an effective start signal and sends the effective start signal to the second control unit 42, so that the system enters a normally open mode.

It should be noted that, after the internal source auxiliary circuit 311, the MPPT circuit 313 and the internal source conversion circuit 314 are all normally started, the operating voltages of the internal source auxiliary circuit 311, the MPPT circuit 313 and the internal source conversion circuit 314 are all provided by the sensor 11.

When the system is in a normally open mode, the external source conversion circuit 323 is turned on, and the charging circuit 321 is turned on. As shown in fig. 4, the first control unit 41 is powered by the internal source energy management unit 31 through one channel of the internal source conversion circuit 314; the first control unit 41 configures one part of subunits in the sensor 11 as an energy acquisition function, and configures the other part of subunits as an information acquisition function; the subunit configured as the energy collection function performs energy collection spontaneously, converts the collected energy into electric energy, and transmits the electric energy to the cold start circuit 312, the internal source auxiliary circuit 311, the MPPT circuit 313 and the internal source conversion circuit 314 in the internal source energy management unit 31 through the energy collection bus to supply power; the subunit configured as the information acquisition function is powered and driven by the internal source energy management unit 31 through the internal source conversion circuit 314 to acquire information; the first processing unit 21 is powered and driven by the internal source energy management unit 31 through the internal source conversion circuit 314 and is controlled to be started by the first control unit 41; sixthly, the second control unit 42 is powered and driven by an external power supply through an external source conversion circuit 323; the first control unit 41 controls the sensor 11 to transmit the acquired information to the first processing unit 21; the first processing unit 21 runs a corresponding algorithm to extract relevant information in the surrounding environment from the received information; when the extracted related information meets the predetermined judgment condition, the first processing unit 21 sends an effective interrupt signal to the second control unit 42, so that the working mode of the system is switched to the trigger mode; and when the extracted related information does not meet the preset judgment condition, the system continues to operate in the normally open mode.

In this mode, the MPPT circuit 313 always detects the output power of the sensor 11, and adjusts the operating parameters of the internal source converter circuit 314 to maximize the output power of the sensor 11. In this mode, the charging circuit 321 receives the electric power output from one channel of the internal source conversion circuit 314 and charges the external power source with the electric power.

When the system is in the trigger mode, the external source switching circuit 323 is turned on, and the charging circuit 321 is turned off. As shown in fig. 5, the first control unit 41 is powered by an external power source through an external source switching circuit 323; the first control unit 41 configures all subunits in the sensor 11 to have an information acquisition function; the sensor 11 is powered and driven by an external power supply through an external source conversion circuit 323 to acquire information; the second processing unit 22 is powered and driven by an external power supply through an external source switching circuit 323 and is controlled to be started by the first control unit 41; the second control unit 42 is powered by an external power supply through an external source conversion circuit 323; sixthly, the first control unit 41 controls the sensor 11 to transmit the acquired information to the second processing unit 22; the second processing unit 22 runs a corresponding algorithm to process the received information, and sends an effective interrupt signal to the second control unit 42 after the processing is completed, so that the operating mode of the system is switched to the start mode.

It should be noted that, when the system is in the normally open mode, only part of the subunits in the sensor 11 are configured as the information acquisition function; and when the system is in the trigger mode, all the subunits are configured as the information collection function. Therefore, the accuracy of the information collected by the sensor 11 in the trigger mode is higher than that in the normally open mode. In the present application, different levels of algorithms may be run for different information accuracies. For example, in the normally open mode, a low power consumption algorithm with low complexity can be run to detect whether a moving object exists or not; in the trigger mode, a highly complex high-level algorithm may be run to identify what the moving object is, and so on.

In the in-situ energy acquisition and information processing system, the processes of energy acquisition and transmission are performed spontaneously, and power supply driving is not needed. And the system adopts the concept of hierarchical processing, and different functional units are called according to different working modes, so that the operating power consumption of the whole system is reduced.

The in-situ energy harvesting and information processing system may be implemented by an integrated circuit or a chip, and is not particularly limited in this application.

By adopting the in-situ energy acquisition and information processing system and the control method thereof in the technical scheme, the processes of energy acquisition and transmission are performed spontaneously without power supply driving; the information acquisition and transmission need to be driven by power supply. Energy collection and information processing are integrated in the system, the operation of the whole system is maintained by means of the energy collected by the system, the self-energy supply of the system is realized, and meanwhile, the reduction of the volume of the system and the reduction of the manufacturing cost are facilitated.
