Description

Power supply device, corresponding Bluetooth device, method, computer device and medium
Technical Field
The present application relates to the technical field of powering bluetooth beacons, and more particularly, to a power supply apparatus for bluetooth beacons, a bluetooth device including the same, a power supply method for bluetooth beacons, and a corresponding computer device and computer-readable storage medium.
Background
With the development of the internet of things market, beacon technology has been widely used. The beacon technology is used for capturing information from and pushing information to mobile devices in a network in a low-cost hardware mode through a low-power consumption Bluetooth mode, and is particularly suitable for being applied to indoor environments with relatively poor signals, such as museums, subway stations, schools, factories, elevators, laboratories and the like. The key advantage of beacon technology is the advantage of bluetooth low energy, which does not require a network connection like WiFi, but only works with two nodes. The bluetooth beacon for signal transmission through bluetooth low energy has low power consumption, but still needs to be powered by a battery.
At present, the power supply mode of the Bluetooth beacon mainly comprises power supply by a disposable dry battery and power supply by charging a solar battery. However, these two power supply methods have their respective problems. Specifically, if a disposable dry battery power supply mode is adopted, the time that the dry battery can be used for the Bluetooth beacon to run is limited, and the problem of replacing the dry battery and maintaining at a later stage exists, so that the use of the Bluetooth beacon is affected. In addition, bluetooth beacons have different power consumption under different operating conditions: when in the dormant state, the power consumption is lower, and when in the broadcast state, the power consumption is higher; therefore, when the bluetooth beacon switches working states, a larger power difference is generated, and the power supply mode of the larger power difference exists between the two working states in a periodical switching manner, so that the power supply of the dry battery is not facilitated, even larger burst current can be generated to break down the dry battery, and the use of the bluetooth beacon is affected. If the solar battery is used for charging and supplying power, the solar battery is necessarily limited by many factors such as illumination intensity, beacon placement position, light energy and electric energy conversion, and the power cannot be supplied stably, so that the stable work of the Bluetooth beacon is affected, and the Bluetooth beacon cannot be used normally.

The terms "comprises," "comprising," and "having" specify the presence of stated features, operations, components, elements, and/or combinations thereof, but do not preclude the presence or addition of one or more other features, operations, components, elements, and/or groups thereof.
The general concept of the application is as follows: unlike the prior art scheme of using a single power supply, a dual power supply is provided, i.e., a first power supply provided by a battery and a second power supply from solar energy, and one of the first power supply and the second power supply is selected as a power supply to power the bluetooth device according to the operating state of the bluetooth beacon.
The application is illustrated below in connection with specific embodiments.
Referring to fig. 1, a bluetooth device using a power supply apparatus 1 according to an embodiment of the present application is shown. The bluetooth device comprises a bluetooth beacon and a power supply means 1 connected to the bluetooth beacon for supplying power thereto. The power supply device 1 includes a battery power supply module 12, a solar power supply module 14, and a power management module 16. Each of the battery power module 12 and the solar power module 14 is connected with its output to an input of the power management module 16. The output of the power management module 16 is connected to the bluetooth beacon to be powered.
The battery power module 12 is configured to provide battery power as a first power source and may include one or more batteries, such as dry cell batteries, other possible batteries (e.g., rechargeable batteries, etc.), or a combination thereof. Herein, a "battery powered module" may be understood broadly to encompass a variety of possible modules, devices or apparatus adapted to be powered by a battery.
In one embodiment, the battery powered module 12 includes only dry cells as the power supply cells; at this time, the battery power supply module 12 may be referred to as a dry battery power supply module. In view of the special functionality of the bluetooth node, the bluetooth node will generally not move after deployment unless a functional disorder occurs, which is advantageous with a dry cell. However, it should be understood that the application is not limited thereto.
The solar power supply module 14 is configured to convert received solar energy into electrical energy and provide photovoltaic power as a second power source according to the converted electrical energy. Herein, a "solar powered module" is to be understood broadly to encompass a variety of possible modules, devices or apparatus adapted to be powered by solar energy. The solar power module 14 includes a photovoltaic module (which may also be referred to as a "solar panel") for converting solar energy into electrical energy. As understood by those skilled in the art, a photovoltaic module converts solar energy into electrical energy at a certain conversion rate (typically not 100%), depending on the photovoltaic material or the like that it employs. The photovoltaic module can be implemented in various possible forms in various possible technologies. In one embodiment, a photovoltaic module includes a plurality of solar cells connected in series and/or parallel. However, it should be understood that the application is not limited thereto. The electrical energy converted by the photovoltaic module may be provided to the bluetooth beacon as a load via the power management module 16.
The power management module 16 is configured to select one of a first power source from the battery power supply module 12 and a second power source from the solar power supply module 14 as a power supply according to an operating state of the connected bluetooth beacon, and supply power to the bluetooth beacon with the power supply.
In one embodiment, the power management module 16 is configured to: selecting the first power source as a power supply source in response to the connected bluetooth beacon being in one of a sleep state and a broadcast state (hereinafter referred to as a "first state"); selecting the second power source as a power supply source in response to the bluetooth beacon being in the other one of the sleep state and the broadcast state (hereinafter referred to as a "second state"); and powering the bluetooth beacon with the power supply.
In view of the low power consumption of the bluetooth beacon in the dormant state and the high power consumption of the bluetooth beacon in the broadcast state, it is advantageous that the first state is the dormant state and the second state is the broadcast state, i.e. the bluetooth beacon is powered with battery power in the dormant state and the bluetooth beacon is powered with photovoltaic power in the broadcast state. Thus, the dry battery can work with relatively low power supply current, which is beneficial to prolonging the service life of the dry battery. However, it should be understood that the application is not limited thereto.
Advantageously, the power management module 16 may be configured to, in case of selecting said second power source as the power supply source: detecting an output current of the second power supply; and selecting the first power supply as the power supply source when the output current of the second power supply is not detected or the output current of the second power supply is detected to be lower than a threshold current. The threshold current may be set appropriately according to circumstances. In this way, it is possible to take into account the fact that the solar power module cannot provide sufficient power, so that the bluetooth beacon can be suitably powered also in such a case.
Further, the power management module 16 may be configured to, in case the second power source is selected as the power supply source: if the abnormal event is continuously detected for a predetermined number of times, it is determined that the solar power module 14 is failed or in an unstable state, and a failure alarm is triggered. For example, the power management module 16 may directly send out a fault signal indicating that the solar power module 14 is faulty, or the power management module 16 may generate a reminder message indicating that the solar power module 14 is faulty, and send the reminder message to the bluetooth beacon, so that the bluetooth beacon sends out a corresponding fault signal. The exception event may be a variety of possible exception events including, for example and without limitation: the output current of the second power supply is not detected; detecting that the output current of the second power supply is lower than a threshold current; etc. The predetermined number of times may be appropriately set according to circumstances, and may be set to 2 times or more, for example. The threshold current may be set appropriately according to circumstances.
The power management module 16 may be configured with other possible functions, as desired. For example, in one embodiment, the power management module 16 is configured with current and/or voltage adjustment functionality to adjust the current and/or voltage received from the power supply to a desired current and/or voltage suitable for provision to the bluetooth beacon. However, this is not necessary. For example, such current and/or voltage regulation may not be necessary, or may be performed outside of the power management module 16, such as within a bluetooth beacon.
The power management module 16 can detect the operational status of the connected bluetooth beacon in a variety of possible ways. For example, in one embodiment, the power management module 16 is configured to: detecting a signal sent by the Bluetooth beacon; when the Bluetooth beacon is detected to send out a broadcast preprocessing signal, judging that the Bluetooth beacon is in a broadcast state; and when the Bluetooth beacon is detected to send out a broadcast completion signal, judging that the Bluetooth beacon is in a dormant state. It should be understood that the application is not limited thereto.
Referring to fig. 2, a power supply device 2 for a bluetooth beacon according to an embodiment of the application is shown. The power supply device 2 includes a battery power supply module 22, a solar power supply module 24, and a power management module 26. The battery powered module 22 includes a dry cell 2202. The solar power module 24 includes a photovoltaic module 2402 and an energy storage element 2404. The photovoltaic module 2402 is configured to receive solar energy and convert the received solar energy into electrical energy. The energy storage element 2404 is connected to the photovoltaic module 2402 for storing electrical energy converted by the photovoltaic module 2402. Specifically, the solar power module 24 stores the converted electrical energy in the energy storage element 2404 by charging the energy storage element 2404 with the converted electrical energy from the photovoltaic module 2402.
Advantageously, the energy storage element 2404 is configured such that: the energy storage element stores at least 1 time the predetermined energy if charged for a predetermined duration in the desired charging mode associated with the solar power module 24. The preset power may be predetermined and may be suitably determined according to circumstances, for example, based on the required power associated with the bluetooth beacon to be powered by the power supply device 2 operating in the second state once. The desired charging mode may be predetermined, may be appropriately determined according to circumstances, and may be determined based on, for example, the desired application environment of the solar power module 24 and the desired operating conditions of the solar power module related to charging the energy storage element 2404 (e.g., without limitation, charging mode (e.g., without limitation, constant current constant voltage (CC/CV), etc.), charging current, rated voltage, etc.). Knowing the desired charging pattern, the amount of energy that can be stored by the energy storage element 2404 being charged for a certain period of time can be determined. The preset duration may be predetermined, may be appropriately determined according to circumstances, and may be determined based on a broadcast interval of the bluetooth beacon or based on a duration in which the bluetooth beacon operates once in the first state, for example. For example, the preset duration may be equal to a broadcast interval of the bluetooth beacon or to a duration for which the bluetooth beacon operates once in the first state. In this manner, it is made possible to achieve that the energy storage element 2404 is charged once enough to store energy for the bluetooth beacon to operate in the second state at least once (e.g., broadcast at least once if the second state is a broadcast state).
Here, the required power associated with the bluetooth beacon operating once in the second state may be determined based on the sum of the power required for each of the related power consuming components involved once to achieve the bluetooth beacon operating once in the second state (e.g., broadcast state), and may be determined to be equal to or greater than the latter, for example. For example, in the case of fig. 2, "related electrical components involved" include the bluetooth beacon itself, the power management module 26, and the solar power module 24; the "required electrical energy" may be based on the sum of: 1) The bluetooth beacon itself operates in the second state once and consumes power, 2) the power management module 26 and the solar power module 24 connected to the bluetooth beacon consume power during the period when the bluetooth beacon operates in the second state once. It is contemplated that "related electrical components" include other possible electrical components, depending on the particular situation. As will be appreciated by those skilled in the art, bluetooth beacons are periodically operated in a broadcast state and a dormant state at a fixed frequency, the duration of the broadcast state, the duration of the dormant state, the broadcast interval, and the time interval between the broadcast state and the dormant state may be fixed and/or predetermined for a given bluetooth beacon, and the power consumption per broadcast, and the power consumption per dormant may be fixed and/or predetermined. In addition, for a given other electrical component involved, such as, but not limited to, a power management module, a solar power module, the electrical energy consumed over a period of time may be predetermined. For example, for a given powered component, such as a bluetooth beacon or power management module, the relevant energy consumption information may be determined by a look-up table or according to a manual.
In one embodiment, a non-sunlight period associated with the solar power module 24 is considered. Specifically, the capacity of the energy storage element 2404 is selected such that the maximum electrical energy that the energy storage element can store is at least M times the preset electrical energy. M may be determined based on the number of times the bluetooth beacon to which the power supply device 2 is connected operates in the second state (e.g., broadcast state) during the non-illuminated period. For example, M may be equal to or greater than the number of times the bluetooth beacon is operated in the second state during the non-illuminated period. In this way, it can be considered to power the bluetooth beacon with photovoltaic power during the non-sunlight period, for example by charging the energy storage element 2404 to its maximum energy storage energy as much as possible when there is sunlight.
The non-sunlight periods and the sunlight periods associated with the solar power module 24 may alternate. In an embodiment, energy storage element 2404 is configured such that: the energy storage element, if charged for a predetermined duration in the intended charging regime associated with the solar power module 24, stores electrical energy that is at least a predetermined multiple of the predetermined electrical energy. For the expected charging manner and the preset duration, reference may be made to the foregoing, and no further description is given here. The preset multiple is determined, for example, such that: the product of the number of times the bluetooth beacon is in the first state and the preset multiple during the sunlit period is at least equal to the sum of the number of times the bluetooth beacon is in the second state during the sunlit period and the number of times the bluetooth beacon is in the second state during the sunless period. As such, it is enabled to realize: the photovoltaic power stored by charging energy storage element 2404 during the sunburn period, in addition to meeting the power demand for the bluetooth beacon to operate in the second state during the sunburn period, can also meet the power demand for the bluetooth beacon to operate in the second state during the next sunless period, such as by charging energy storage element 2404 at a suitable frequency for a suitable time. For example, the solar power module 24 may be configured to: during the daylight hours, the energy storage element 2404 is charged at least each time the bluetooth beacon is in the first state. That is, during periods of sunlight, the solar power module 24 charges the energy storage element 2404 with electrical energy from the photovoltaic module 2402 whenever the bluetooth beacon is in a dormant state.
As described above, the duration of the broadcast state, the duration of the sleep state may be fixed and/or predetermined for a given bluetooth beacon. Thus, given an unoccupied time period, the number of times a given bluetooth beacon is in/operated in a first state and the number of times it is in/operated in a second state during that unoccupied time period are both predictable and determinable; given a period of insolation, the number of times a given bluetooth beacon is in/operated in a first state and the number of times it is in/operated in a second state during the period of insolation are both contemplated and determined.
Each of the above-described non-sunlight periods and sunlight periods may be suitably determined in various ways, such as may be predicted and determined based on various possible factors, which may include, for example and without limitation: season, weather, location of the solar power module 24, etc. In one embodiment, there is a period of sunlight corresponding to a daytime period of the day (e.g., 12 hours), and a period of no sunlight corresponding to a nighttime period of the day (e.g., 12 hours). The application is not limited thereto. For example, it is contemplated that a period of sunlight corresponds to a period of sunlight in a daytime period, a period of no sunlight corresponds to a period of no sunlight or sunlight is weak in a daytime period, or other circumstances.
Considering that the super capacitor has the advantages of long service life, fast charge and discharge speed, high power density (strong energy storage capability), etc., it is advantageous for the energy storage element 2404 to be implemented as a super capacitor, but the application is not limited thereto. Other types of energy storage technologies, such as conventional capacitors, batteries, etc., are possible for energy storage element 2404.
The modules of the power supply of the present application and the bluetooth beacons powered by the power supply may take a variety of possible forms, such as, but not limited to, chips, printed circuit boards, combinations thereof, and the like.
Referring to fig. 3, a power supply method for a bluetooth beacon according to an embodiment of the present application is schematically illustrated. The power supply method includes step S310, step S320, and step S330.
In step S310, in response to the bluetooth beacon being in a sleep state, a first power source provided by a battery is selected as a power supply source.
In step S320, a second power source provided by the solar-converted power is selected as the power source in response to the bluetooth beacon being in a broadcast state.
In step S330, the bluetooth beacon is powered by the power supply.
The power supply method can use the power supply device of the application and is applicable to the power supply device and the Bluetooth equipment of the application. In the case of implementing the power supply method using the power supply apparatus of the present application, each step of the power supply method may be performed by a power management module of the power supply apparatus.

In particular, the power supply method of the present application may include any one of or any suitable combination of the operations (e.g., detection, determination, selection, alarm triggering, etc.) described above as being executable by the power management module of the power supply apparatus of the present application.
