In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the technical solutions should be considered that the combination does not exist and is not within the scope of protection claimed by the present invention.
It should be noted that, at present, the emergency energy storage power supply is widely applied to daily life, for example, when a power grid fails, the emergency energy storage power supply can provide power for important equipment in a family, such as lighting fixtures, communication equipment, refrigerator air conditioners and the like, so as to ensure the basic life demands and the normal operation of electrical equipment; and for example, when the user is camping outdoors or exploring outdoors, the emergency energy storage power supply can provide power support for open illumination, mobile phone charging and the like, and convenience and safety are added for the outdoor activities of the user.
In order to quickly find an emergency energy storage power supply when a user needs, the existing GPS positioning module 3 is generally configured in the emergency energy storage power supply, and the position of the GPS positioning module can be sent to a mobile phone of the user, but the emergency energy storage power supply can always supply power for the GPS module, so that high energy consumption is caused.
Therefore, in order to solve the above-mentioned drawbacks, the present embodiment provides an emergency energy storage power system, which can transmit a generated startup signal to a power supply module through a power supply control module when a mobile device sends a positioning instruction, and the power supply module supplies power to the positioning module after receiving the startup signal so as to send position information to the mobile device. Compared with the existing emergency energy storage power supply which is used for supplying power for the GPS module all the time, the embodiment can supply power when receiving a positioning instruction, and further positioning is achieved, so that energy consumption can be reduced.
For easy understanding, the emergency energy storage power supply system provided in the embodiment of the present application is specifically described below with reference to fig. 1 to 4.
Referring to fig. 1, fig. 1 is a block diagram of a first embodiment of an emergency energy storage power system according to an embodiment of the present invention.
As shown in fig. 1, in this embodiment, the emergency energy storage power supply system includes: a power supply control module 1, a power supply module 2 and a positioning module 3;
the power supply module 2 is respectively connected with the power supply control module 1, the positioning module 3 and the storage battery, and the power supply control module 1 is also connected with the positioning module 3 and the mobile equipment.
It should be noted that, the above-mentioned battery can be used to provide electric energy for the user, i.e. can be configured to connect the power supply interface with the battery, and through the power supply interface, the user can provide power support for, for example, lighting fixtures, mobile phone charging, etc.
It can be appreciated that the emergency energy storage power supply system can be arranged in the emergency energy storage power supply and can be configured with a corresponding APP, namely, a user can install the APP on mobile equipment (such as a mobile phone, a bracelet and the like), can check information such as the current position and the current electric quantity of the emergency energy storage power supply through the APP, and can also support checking information of current charging equipment.
Meanwhile, the APP can also support whether the remote control power supply interface supplies power or not, namely if the user prohibits the power supply of the interface A, when equipment which is not used is connected to the interface A, the emergency energy storage power supply cannot supply power to the equipment, and safety is further improved.
The power supply control module 1 is configured to generate a start signal when receiving a positioning instruction generated by the mobile device, and transmit the start signal to the power supply module 2.
It should be understood that the positioning instruction may be an instruction generated when a user has a positioning requirement, for example, when the user locates a button in an APP interface by using a motor, the mobile device may generate the positioning instruction to the power supply control module 1, or when the APP is automatically detected to be turned on, generate the positioning instruction to the power supply control module 1; of course, the timing of generating the positioning command can be set according to the actual situation, which is not limited in this embodiment.
In actual use, the power supply control module 1 can generate a start signal after receiving a positioning instruction generated by the mobile device, and transmit the start signal to the power supply module 2.
The power supply module 2 is configured to transmit a power supply voltage provided by the storage battery to the positioning module 3 for power supply when the start signal is received.
When the positioning instruction is not received, no starting signal is generated by the power supply control module 1, and therefore the power supply module 2 can not transmit the power supply voltage provided by the storage battery to the positioning module 3 for power supply, the positioning module 3 is in a shutdown state, and when the positioning instruction is received, a user is indicated to have positioning requirements, and the power supply module 2 can transmit the power supply voltage to the positioning module 3 for power supply.
The positioning module 3 is configured to start when the power supply voltage is received, position a current location, and send obtained location information to the mobile device.
The positioning module 3 can establish communication with a base station, and can position an emergency energy storage power supply through positioning signals.
It should be noted that, after receiving the power supply voltage, the positioning module 3 may switch from the power-off state to the normal working state, position the current position to obtain position information, then transmit the position information to the power supply control module 1, and the power supply control module 1 sends the position information to the mobile device, thereby completing positioning.
Further, in this embodiment, after the positioning module 3 completes positioning, the power is still switched back to the off state, so as to further reduce energy consumption, specifically:
the positioning module 3 is further configured to feed back the positioning signal to the power supply control module 1;
the power supply control module 1 is further configured to output a shutdown signal to the power supply module 2 after receiving the positioning signal;
the power supply module 2 is further configured to stop outputting the power supply voltage to the positioning module 3 when the shutdown signal is received.
In actual use, the power supply control module 1 can send to the mobile device after receiving the position information, and can generate a shutdown signal to the power supply module 2, and the power supply module 2 can stop outputting the power supply voltage to the positioning module 3 after receiving the shutdown signal.
In a specific implementation, when the power supply control module 1 does not receive a positioning instruction, the power supply module 2 does not transmit the power supply voltage of the storage battery to the positioning module 3 for power supply, the positioning module 3 is in a shutdown state, when a user has a positioning requirement, the power supply control module 1 receives the positioning instruction and generates a startup signal to the power supply module 2, the power supply module 2 transmits the power supply voltage to the positioning module 3, the positioning module 3 is switched from the shutdown state to the startup state for positioning, and is switched to the shutdown state after positioning is finished. Compared with the existing emergency energy storage power supply which is used for supplying power for the GPS module all the time, the embodiment can supply power when receiving a positioning instruction, and further positioning is achieved, so that energy consumption can be reduced.
Further, considering that if the position of the emergency energy storage power supply is not changed, the positioning is not needed to be performed by restarting, and the position information obtained last time can be directly sent to the mobile device, that is, as shown in fig. 1, in this embodiment, the emergency energy storage power supply system further includes: a pressure detection module 4; wherein, the pressure detection module 4 is connected with the power supply control module 1.
It should be noted that, the pressure detection module 4 may include pressure sensors, and the number of specific sensors may be set according to actual situations, and in this embodiment, the pressure sensors may be set at the bottom of the emergency energy storage power supply, if the position of the emergency energy storage power supply moves, the pressure received at the bottom may change, and of course, other positions may also be used.
The pressure detection module 4 is used for collecting the external pressure and transmitting the generated pressure signal to the power supply control module 1; the power supply control module 1 is further used for judging whether the pressure signal is changed or not; and the power supply control module 1 is further configured to send the last obtained location information to the mobile device when receiving a positioning instruction generated by the mobile device if not.
It can be understood that the pressure detection module 4 can transmit the collected external pressure to the power supply control module 1, the power supply control module 1 can judge whether the external pressure corresponding to the pressure signal changes from the last positioning time to the current time, if not, the position of the emergency energy storage power supply is not moved, and when a positioning instruction is received, the last obtained position information can be sent to the mobile device; if the position of the emergency energy storage power supply is changed, the position of the emergency energy storage power supply can be indicated to be moved, and the power supply control module 1 normally transmits the generated start-up signal to the power supply module 2 so as to switch the positioning module 3 to a start-up state for positioning.
As another implementation manner, in order to ensure the accuracy of the last transmitted position information, the power supply control module 1 of this embodiment may further be provided with a self-positioning policy, that is, corresponding self-positioning frequent degrees may be set according to different positions, and self-positioning may be performed under the self-positioning frequent degrees to check whether the current position is moved, if not, the last position information may still be transmitted, and if moved, the latest position information may be transmitted.
It should be emphasized that, considering that under the self-positioning strategy, the positioning module 3 needs to switch from the off state to the on state, a series of starting processes, such as self-checking, loading, initializing, etc., are required, and these operations consume a certain amount of electric energy, so in order to further reduce the energy consumption, the above power supply control module 1 may record that the corresponding self-positioning frequent degree is set for each position, the corresponding self-positioning frequent degree of each position may be set according to the actual situation, and under the condition that the external pressure corresponding to the pressure signal is not changed, the corresponding self-positioning frequent degree is obtained according to the previous position information, and it is determined whether the energy consumption of restarting the positioning module 3 under the frequent degree is higher or the energy consumption of the positioning module under the low power consumption is higher than the normal energy consumption again, so as to select the mode with lower energy consumption to perform the work.
For example, when the emergency energy storage power supply is in home, the self-positioning frequency is 0.3 times/day, when the self-positioning frequency is 0.7 times/day near a certain reservoir, if the basic energy consumption required by positioning of the positioning module 3 is kW/time, when the one-time power consumption of restarting is mW/time, the standby energy consumption of waiting for one day is nW/day, further, in one day, the energy consumption required by positioning in a restarting mode is 0.3 (m+k), the energy consumption required by positioning in a standby mode is n+0.3k, and by comparing the magnitudes of 0.3 (m+k) and n+0.3k, a mode with lower energy consumption can be selected as the working mode of the self-positioning strategy in home; in the same day, the energy consumption required by positioning in a restarting mode is 0.7 (m+k) near a certain reservoir, the energy consumption required by positioning in a standby mode is n+0.7k, and a mode with lower energy consumption can be selected as a self-positioning strategy working mode near the certain reservoir by comparing the sizes of 0.7 (m+k) and n+0.7k; and further, after the last positioning is finished, a future working mode can be determined to work according to the current position information, so that the energy consumption is further saved.
As another implementation manner, when the self-positioning strategy is executed, if the position is not moved, the self-positioning frequency can be reduced along with the increase of the period of non-movement, for example, the self-positioning frequency is 0.7 times/day when the position is near a certain reservoir, a standby mode is currently adopted, if the position is not moved within one day, the self-positioning frequency can be reduced to 0.5 times/day, and then the working mode of the self-positioning strategy is selected according to the adjusted self-positioning frequency, so that the mode may be switched to a restarting mode.
In a specific implementation, the pressure detection module 4 can be arranged in the emergency energy storage power supply system, whether the emergency energy storage power supply moves or not can be judged through the pressure detection module 4, if so, the positioning module 3 is restarted for positioning, and if not, the power supply control module 1 can send the last position information to the mobile equipment, the positioning module 3 is not needed for positioning, and the energy consumption is further saved.
In this embodiment, when the power supply control module 1 does not receive the positioning instruction, the power supply module 2 does not transmit the power supply voltage of the storage battery to the positioning module 3 for power supply, the positioning module 3 is in a shutdown state, when the user has a positioning requirement, the power supply control module 1 receives the positioning instruction and generates a startup signal to the power supply module 2, the power supply module 2 transmits the power supply voltage to the positioning module 3, the positioning module 3 is switched from the shutdown state to the startup state for positioning, and is switched to the shutdown state after the positioning is finished. Compared with the existing emergency energy storage power supply which is used for supplying power for the GPS module all the time, the embodiment can supply power when receiving a positioning instruction, and further positioning is achieved, so that energy consumption can be reduced.
Referring to fig. 2, fig. 2 is a block diagram illustrating a second embodiment of an emergency energy storage power system according to an embodiment of the present invention.
Under normal conditions, the positioning module 3 can communicate with the base station according to the signal strength of the standard positioning signal, but considering that when the emergency energy storage power supply is close to the base station, the signal strength of the signal can be reduced to further reduce the energy consumption, so in this embodiment, as shown in fig. 2, the power supply control module 1 is further configured to determine the channel characteristic between the mobile device and the target base station when receiving the positioning command generated by the mobile device, and adjust the start signal according to the channel characteristic.
The target base station may be a base station communicating with the positioning module 3, and the channel characteristics may represent characteristics such as a distance of signal transmission between the power supply control module 1 and the target base station, and strength of signal transmission.
The power supply module 2 is further configured to adjust the power supply voltage according to the adjusted start signal; the positioning module 3 is further configured to adjust a signal strength of a positioning signal transmitted to the target base station according to the adjusted power supply voltage, and position the current position according to the adjusted positioning signal.
When in actual use, the power supply control module 1 can determine the channel characteristics between the power supply control module 1 and the target base station when receiving the positioning instruction, adjust the start-up signal transmitted to the power supply module 2 according to the channel characteristics, and the power supply module 2 can control the power supply voltage transmitted to the positioning module 3 after receiving the adjusted start-up signal;
for example, if the distance between the positioning module 3 and the target base station is closer, the power supply module 2 may reduce the power supply voltage transmitted to the antenna in the positioning module 3, so that the transmission power of the positioning module 3 is reduced, the signal strength of the positioning signal is reduced, and the positioning signal can still be positioned through the reduced positioning signal due to the closer distance, so that the energy consumption is further reduced.
It can be understood that the power supply control module 1 may store signal intensities of the startup signals corresponding to different channel characteristics, so that the startup signals can be adjusted to a proper intensity according to the channel characteristics, and the positioning signals can be adjusted to a proper intensity to complete positioning.
Further, in this embodiment, by sending a reference signal to the target base station, when receiving an acknowledgement signal fed back by the target base station, determining the corresponding channel characteristic based on the transmission duration, as further shown in fig. 2, specifically, the emergency energy storage power supply system further includes: a ranging module 5;
wherein, the distance measuring module 5 is connected with the power supply control module 1;
the power supply control module 1 is further configured to transmit, when receiving a positioning instruction generated by the mobile device, a generated ranging signal to the ranging module 5;
the ranging module 5 is configured to transmit the generated reference signal to a target base station and receive a confirmation signal fed back by the target base station when receiving the ranging signal;
the power supply control module 1 is further configured to record a transmission duration between transmitting the reference signal and receiving the acknowledgement signal, and determine a channel characteristic according to the transmission duration.
It should be understood that when the power supply control module 1 receives the positioning instruction, a ranging signal may be generated to the ranging module 5, the ranging module 5 may generate a reference signal after receiving the ranging signal and transmit the reference signal to the target base station, the target base station may feedback an acknowledgement signal to the ranging module 5 after receiving the reference signal, and further the power supply control module 1 may record a transmission duration consumed between transmitting the reference signal and receiving the acknowledgement signal, and determine the channel characteristic at the location according to the transmission duration.
It should be noted that, after each time of measuring the channel characteristic, the channel characteristic and the corresponding position may be saved, so that the signal strength of the corresponding positioning signal may be directly determined according to the channel characteristic for positioning when the position is verified by the self-positioning strategy.
Further, the ranging module 5 includes: a wireless transmitting unit and a wireless receiving unit;
wherein, the wireless transmitting unit and the wireless receiving unit are both connected with the power supply control module 1;
the power supply control module 1 is further configured to transmit, when receiving a positioning instruction generated by the mobile device, a generated ranging signal to the wireless transmitting unit;
the wireless transmitting unit is used for transmitting the generated reference signal to a target base station when the ranging signal is received;
the wireless receiving unit is configured to receive an acknowledgement signal fed back by the target base station, and transmit the acknowledgement signal to the power supply control module 1.
It is understood that the wireless transmitting unit may be a unit for transmitting a ranging signal, for example, an antenna, etc., and the wireless receiving unit may be a unit for receiving an acknowledgement signal, or an antenna may be used.
It is emphasized that the wireless transmitting unit and the wireless receiving unit are separately arranged, so that signal interference between the wireless transmitting unit and the wireless receiving unit can be reduced, and the accuracy of the measured transmission duration is further improved.
According to the embodiment, the startup signal can be adjusted according to the channel characteristics between the power supply control module 1 and the target base station, the adjusted startup signal is transmitted to the power supply module 2, the power supply module 2 can adjust the power supply voltage according to the received startup signal, and the strength of the positioning signal emitted by the positioning module 3 can be changed, so that the purpose of saving energy consumption is achieved.
Referring to fig. 3, fig. 3 is a block diagram of a third embodiment of an emergency energy storage power system according to an embodiment of the present invention.
As shown in fig. 3, in order to accurately adjust the signal strength of the positioning signal, the embodiment may be implemented by using a plurality of positioning units, that is, controlling the number of the working positioning units and controlling the power voltage transmitted to each working positioning unit, so as to find an equalizing point of the number and the total energy consumption, thereby implementing accurate adjustment. In this embodiment, the power supply module 2 includes: at least two adjusting units; the positioning module 3 comprises: at least two positioning units; each adjusting unit is connected with the power supply control module 1 and the storage battery, each positioning unit is connected with the power supply control module 1, and each positioning unit is also connected with the corresponding adjusting unit.
The power supply control module 1 is further configured to adjust the startup signal according to the channel characteristic, and transmit the adjusted startup signal to a corresponding adjusting unit.
Further, the power supply control module 1 is further configured to determine a corresponding mapping relationship according to the channel characteristic, where the mapping relationship is a relationship between the number of the positioning units and an energy saving coefficient of the positioning units;
the power supply control module 1 is further configured to select a target number and a target energy-saving coefficient based on the mapping relationship, and adjust the start-up signal based on the target number and the target energy-saving coefficient.
It should be noted that, the mapping relationship is a relationship between the number of the working positioning units and the energy-saving coefficient of the working positioning units, and the energy-saving coefficient of the working positioning units may be a coefficient of current energy consumption under the adjustment of signal strength and a coefficient of standard energy consumption of the positioning units.
Because of the different relation between the number and the energy-saving coefficient under different channel characteristics, for the convenience of the following description, the transmission distance between the target base station and the target base station is described as the channel characteristic, that is, if the standard energy consumption of a single working positioning unit is P0 and the number of the working positioning units is N and the corresponding energy-saving coefficient under different N is DThe current energy consumption of a further operating positioning unit is +.>The total energy consumption of the N operating positioning units is +.>；
The total energy consumption of the number of differently operated positioning units can be obtained from the measurement, in advance, at the corresponding transmission distance D, and thus the relationship between the number at D and the energy saving coefficient, for example when n=1,further->=100%, when n=2>Further->=60%, when n=3 +.>Further->=30%; and by analogy, the mapping relation between the quantity and the energy-saving coefficient under all channel characteristics is obtained.
When the method is actually used, a mode with the minimum power consumption can be selected according to the determined mapping relation, the quantity corresponding to the mode with the minimum power consumption is used as the target quantity, the corresponding energy-saving coefficient is used as the target energy-saving coefficient, and then the start-up signal is controlled to be adjusted through the target quantity and the target energy-saving coefficient.
The adjusting unit is further used for adjusting the power supply voltage according to the adjusted start-up signal and transmitting the adjusted power supply voltage to the corresponding positioning unit; the positioning unit is also used for adjusting the signal intensity of the positioning signal according to the adjusted power supply voltage and positioning the current position through the adjusted positioning signal.
It can be understood that after the adjusting unit receives the adjusted start signal, the number of the working positioning units and the power supply voltage transmitted to the working positioning units can be controlled, the adjusted power supply voltage is transmitted to the working positioning units, and the positioning units can adjust the signal intensity of the positioning signals after receiving the power supply voltage, so that energy consumption is saved.
Further, in order to reduce circuit loss, the adjusting unit in this embodiment may be implemented by using a MOS transistor, that is, referring to fig. 4, fig. 4 is a schematic circuit diagram of a third embodiment of the emergency energy storage power supply system according to the embodiment of the present invention.
As shown in fig. 4, the adjusting unit includes: a first MOS transistor MOS1 and a second MOS transistor MOS2;
the grid electrode of the first MOS tube MOS1 and the drain electrode of the first MOS tube MOS1 are connected with the power supply control module 1, the source electrode of the first MOS tube MOS1 is connected with the grid electrode of the second MOS tube MOS2, the drain electrode of the second MOS tube MOS2 is connected with the storage battery, and the source electrode of the second MOS tube MOS2 is connected with the corresponding positioning unit.
It should be noted that, the first MOS transistor MOS1 and the second MOS transistor MOS2 may both be N-channel MOS transistors, in this embodiment, three adjusting units and three positioning units are used for performing the description, that is, as shown in fig. 4, signals output from OUT1 to OUT4 of the power supply control module 1 may be the start signal, and the OUT1 pin may output a voltage for adjusting the conduction degree of the second MOS transistor MOS2 to the gate of the second MOS transistor MOS2, where the first MOS transistor MOS1 may control whether the second MOS transistor MOS2 connected to the first MOS transistor MOS1 is turned on, so as to control whether the corresponding positioning unit works.
For example, if the target number is 2 and the target energy saving coefficient is 60%, 60% of the gate voltage corresponding to the complete conduction of the second MOS transistor MOS2 can be output through the OUT1 pin, so that the conduction degree of the second MOS transistor MOS2 is 60%, meanwhile, the conduction number of the first MOS transistor MOS1 can be controlled to be 2 through the OUT2 pin to the OUT4 pin, for example, the voltages can be output through the OUT2 pin and the OUT3 pin, the first MOS transistor MOS1 connected with the OUT2 pin and the first MOS transistor MOS1 connected with the OUT3 pin are controlled to be conducted, the first MOS transistor MOS1 connected with the OUT4 pin is not conducted, further, the positioning unit 1 can receive 60% of the power voltage, the positioning unit 2 can receive 60% of the power voltage, and the positioning unit 3 does not work.
Further, in order to make the working voltages received by the working positioning unit consistent, the embodiment may connect a voltage stabilizing module between the drain of the first MOS transistor MOS1 and the OUT1 pin, where the voltage stabilizing module may include: the voltage stabilizing chip U, the first capacitor C1 and the second capacitor C2;
the input end (VIN in fig. 4) of the voltage stabilizing chip U is connected to the second end of the first capacitor C1 and the power supply control module 1 (OUT 1 in fig. 4), the ground end (GND in fig. 4) of the voltage stabilizing chip U is grounded, the ground end of the voltage stabilizing chip U is further connected to the first end of the first capacitor C1 and the first end of the second capacitor C2, and the output end (VOUT in fig. 4) of the voltage stabilizing chip U is connected to the second end of the second capacitor C2 and the drain electrode of the first MOS transistor MOS 1.
It can be understood that the voltage received by the grid electrode of the second MOS transistor MOS2 can be controlled to be consistent by the power supply control module 1 through the voltage stabilizer, so that the conduction degree of the second MOS transistor MOS2 is controlled to be consistent, and the power supply voltage received by the working positioning unit is controlled to be consistent.
The embodiment can control the number of the working positioning units and the power supply voltage received by each positioning unit, thereby realizing the reduction of power consumption.
