Detailed Description

In order to make those skilled in the art better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application shall fall within the scope of the protection of the embodiments in the present application.

It should be noted that the first and second values in this application are only for distinguishing names, do not represent sequential relationships, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features, for example, a first preset time threshold, a second preset time threshold, a first time, a second time, a first comparison result, a second comparison result, a first timing circuit, a second timing circuit, a first pair of high and low levels, and a second pair of high and low levels.

The following further describes specific implementations of embodiments of the present application with reference to the drawings of the embodiments of the present application.

The first embodiment,

As shown in fig. 1A, fig. 1A is a flowchart of a power supply control method according to an embodiment of the present application, where the power supply control method includes the following steps:

step S101, monitoring the solar charging state and the order receiving state of the shared bicycle, and correspondingly determining the duration of the current uncharged state and the duration of the current no-order state.

The solar charging state includes two states, one is a state of supplying power to the whole circuit system of the shared bicycle by collecting electric energy converted from solar energy, and the other is a state of not irradiating the sun by the solar panel for collecting solar energy and not supplying power to the whole circuit system of the shared bicycle. The order receiving state includes two types, one is an order state which indicates that the shared bicycle is in idle state, and the other is an order-free state which indicates that the shared bicycle is in use. In this example, the lock switch state of the lock control circuit indicates the order receiving state, and optionally, the lock is closed, the order receiving state is the order-free state, the lock is open, and the order receiving state is the order-available state.

The current uncharged duration represents the duration of the shared bicycle in an uncharged state, and the current order-free state duration represents the duration of the shared bicycle in an idle state.

Step S102, if the current uncharged duration and the current no-order state duration meet a preset silent state condition of the shared bicycle, controlling the power supply system to enter a low-power consumption power supply mode, wherein the preset silent state condition at least comprises: the current uncharged duration is longer than a first preset duration threshold, and the current order-free state duration is longer than a second preset duration threshold.

It should be noted that the first preset duration threshold and the second preset duration threshold may be set appropriately by those skilled in the art according to actual requirements, or determined by analyzing a large number of used range preset duration thresholds in processing meeting a large number of low power consumption power supply modes, and the first preset duration threshold and the second preset duration threshold may be set to be the same or different, which is not limited in this embodiment of the present application. For example, the first preset duration threshold is set to 168 hours (hour, abbreviated as h), and the second preset duration threshold is set to 120 h; for another example, the first preset duration threshold and the second preset duration threshold are both set to 240 h. The first preset time period threshold may also be expressed in units of time such as seconds, minutes, days, months, etc., and the above description is exemplary in units of time such as hours, and does not represent that the embodiment of the present application is limited thereto.

The silent state comprises the scenes of warehouse accumulation, vehicle detaining, long-time no riding and the like. The preset silent state condition represents that the shared bicycle is in a silent state under the condition, and the condition can be understood that the shared bicycle is idle for a long time and has no charge.

More specifically, when the preset silent time duration H is reached, the vehicle automatically enters the low-power-consumption power supply mode, so that unnecessary standby power consumption is reduced, the low power rate and the no-heartbeat rate of the vehicle are effectively reduced, the vehicle timely enters the low-power-consumption power supply mode, and the battery utilization rate is improved. When the vehicle resumes charging or newly-added orders and the like do not meet the silent condition, the whole circuit system of the shared vehicle can automatically exit the low-power-consumption power supply mode through hardware logic, so that the vehicle operation efficiency is improved, and the operation and maintenance cost is reduced.

In other words, in the related art, it is impossible to detect whether the sharing bicycle is in a silent state, so that the power supply system of the sharing bicycle is always in a high power consumption output mode, and the battery utilization rate is reduced. In the embodiment of the application, the solar charging state and the order receiving state of the shared bicycle are monitored, and the duration of the current uncharged state and the duration of the current no-order state are correspondingly determined; if the current uncharged duration and the current order-free state duration meet a preset silent state condition of the shared bicycle, controlling the power supply system to enter a low-power-consumption power supply mode, wherein the preset silent state condition at least comprises: the current uncharged duration is longer than a first preset duration threshold, and the current order-free state duration is longer than a second preset duration threshold, so that the consumption of the battery of the shared bicycle is timely reduced under the background of long-term idling and no charging, the battery utilization rate is improved, and the operation and maintenance cost is reduced.

Specifically, the above power supply control method may be performed by a power supply system, which may include a first timing circuit, a second timing circuit, and a logic control circuit.

The first timing circuit can monitor the solar charging state of the shared bicycle, time the current uncharged duration and output a first comparison result of the current uncharged duration and a first preset duration threshold.

The second timing circuit may monitor an order receiving state of the shared bicycle, time a current order-free state duration, and output a second comparison result between the current order-free state duration and a second preset duration threshold.

The logic control circuit may be coupled to the first timing circuit and the second timing circuit. The logic control circuit can respectively obtain a first comparison result and a second comparison result from the first timing circuit and the second timing circuit, judge whether the first comparison result and the second comparison result meet the preset silent state condition of the shared bicycle, if so, control the power supply system to enter a low-power-consumption power supply mode,

the preset silence state conditions may include at least: the first comparison result indicates that the duration of the current uncharged state is greater than a first preset duration threshold, and the second comparison result indicates that the duration of the current order-free state is greater than a second preset duration threshold.

In some examples, the first preset duration threshold may be equal to the second preset duration threshold.

Example II,

In an embodiment of the present application, optionally, as shown in fig. 1B, in an embodiment of the present application, as a scheme based on the first embodiment, fig. 1B is a flowchart of a power supply control method according to another embodiment of the present application, and the embodiment of the present application may include the following steps S201 to S204. Step S201, acquiring a charging state of a solar charging circuit and a lock switching state of a lock control circuit; and if the charging state is changed into uncharged state at the first moment, starting timing based on the first moment, determining the current uncharged duration, and if the lock switch state is changed into lock closing state at the second moment, starting timing based on the second moment, and determining the current order-free state duration.

In the embodiment of the present application, the timing is started based on the first time and the timing is started based on the second time, and any timer or timing circuit having a timing function may be used.

The charging state of the solar charging circuit comprises charging and non-charging, the charging state of the solar charging circuit comprises charging and non-charging data information, and whether the charging circuit is charged or not can be judged according to the data information. The data information may be, for example, a charging voltage or a charging current. And when the charging state is changed from charging to non-charging, starting timing to obtain the current non-charging duration.

The lock switching state of the lock control circuit comprises lock opening and lock closing, the lock switching state of the lock control circuit comprises data information of lock opening and lock closing, whether the shared bicycle is in an idle state or not can be judged according to the data information, the lock opening corresponds to the fact that the shared bicycle is in a use state and has an order, and the lock closing corresponds to the fact that the shared bicycle is in an idle state and has no order. And when the switch state of the lock is changed from lock opening to lock closing, timing is started to obtain the duration of the current order-free state.

In the embodiment of the application, the charging state of the solar charging circuit and the lock switching state of the lock control circuit are obtained; if the charging state is changed into uncharged state at the first moment, timing is started based on the first moment, the current uncharged duration is obtained in real time, and the accuracy of the current uncharged duration is improved; if the switch state of the vehicle lock is changed to be the vehicle lock closing state at the second moment, timing is started based on the second moment, the duration of the current order-free state is obtained in real time, and the accuracy of the duration of the current order-free state is improved.

Step S202, judging a first comparison result between the current uncharged duration and a first preset duration threshold, and judging a second comparison result between the current order-free state duration and a second preset duration threshold; and performing logical AND operation on the first comparison result and the second comparison result to judge whether the preset silent state condition is met.

Step S202 is configured to determine whether the current uncharged duration and the current no-order state duration satisfy a preset silent state condition of the shared bicycle. The first comparison result comprises a high level and a low level, the high level indicates that the duration of the current uncharged state is greater than a first preset duration threshold, and the low level indicates that the duration of the current uncharged state is less than or equal to the first preset duration threshold. The second comparison result comprises a high level and a low level, the high level indicates that the duration of the current order-free state is greater than a second preset duration threshold, and the low level indicates that the duration of the current order-free state is less than or equal to the second preset duration threshold.

In this example, when performing a logical and operation, an and gate or an and circuit may be used, as long as the and operation can be performed on two comparison results, and the embodiment of the present application is not limited thereto. And performing logical AND operation on the first comparison result and the second comparison result to obtain a logical AND operation result, wherein the logical AND operation result comprises a high level and a low level, the high level indicates that the preset silent state condition is met, and the low level indicates that the preset silent state condition is not met.

In the embodiment of the application, two comparison results are obtained through two times of judgment, and the two comparison results are subjected to logic AND operation, so that whether the preset silent state condition is met or not is judged.

When the preset silent state condition is satisfied in step S202, step S203 is executed, and if the current uncharged duration and the current no-order state duration satisfy the preset silent state condition of the shared bicycle, the power supply system is controlled to enter a low-power-consumption power supply mode.

It should be noted that step S203 is the same as step S102 in the first embodiment, and is not repeated herein.

When the preset silent state condition is not satisfied in step S202, step S204 is executed, for example, in step S204, if the current uncharged duration and the current no-order state duration do not satisfy the preset silent state condition, the power supply system is controlled to enter a normal power supply mode, and the power supply power of the power supply system in the normal power supply mode is greater than the power supply power of the power supply system in the low power consumption power supply mode.

The condition that the preset silence state is not satisfied comprises the following three situations, namely a first situation: the current uncharged duration is less than or equal to a first preset duration threshold, and the current order-free state duration is greater than a second preset duration threshold; the second case: the current uncharged duration is longer than a first preset duration threshold, and the current order-free state duration is less than or equal to a second preset duration threshold; the third situation: the duration of the current uncharged state is less than or equal to a first preset duration threshold, and the duration of the current order-free state is less than or equal to a second preset duration threshold. That is to say, the sharing bicycle starts to charge or has an order, the power supply system enters a normal power supply mode, and the sharing bicycle automatically recovers to a normal standby mode, so that the battery utilization rate is improved, and the operation and maintenance cost is reduced.

the preset silence state conditions include at least: the first comparison result indicates that the duration of the current uncharged state is greater than a first preset duration threshold, and the second comparison result indicates that the duration of the current order-free state is greater than a second preset duration threshold. In some examples, the first preset duration threshold may be equal to the second preset duration threshold.

More specifically, when the preset silent time duration H is reached, the vehicle automatically enters the low-power-consumption power supply mode, so that unnecessary standby power consumption is reduced, the low power rate and the no-heartbeat rate of the vehicle are effectively reduced, the vehicle timely enters the low-power-consumption power supply mode, and the battery utilization rate is improved. When the vehicle resumes charging or newly-added orders and the like do not meet the silent condition, the whole circuit system of the shared vehicle can automatically exit the low-power-consumption power supply mode through hardware circuit configuration, which is beneficial to improving the vehicle operation efficiency and reducing the operation and maintenance cost.

The switch circuit is turned off, the power supply system enters a low-power-consumption power supply mode, the external communication equipment can report the shared bicycle data information to the server at a long time interval, the switch circuit is turned on, the power supply system enters a normal power supply mode, and the external communication equipment can report the shared bicycle data information to the server at a short time interval or in real time.

When the first timing circuit is used for timing, in an implementation manner, the first timing circuit inputs a judgment result of the solar charging state of the sharing bicycle, and the judgment result comprises charging, changing the charging state from charging to non-charging, non-charging and changing the charging state from non-charging to charging; in another implementation manner, the first timing circuit inputs the solar charging state of the sharing bicycle, determines the solar charging state of the sharing bicycle, and starts timing based on the first time when the charging state is changed to be uncharged at the first time. When the second timing circuit performs timing, in an implementation manner, the second timing circuit inputs a judgment result of the lock switch state of the lock control circuit, and the judgment result includes that the lock is opened, the lock switch state is changed from the lock opening state to the lock closing state, the lock is closed, and the lock switch state is changed from the lock closing state to the lock opening state; in another implementation manner, the second timing circuit inputs the lock switch state of the lock control circuit, determines the lock switch state of the lock control circuit, and starts timing based on the second time when the lock switch state changes to lock off at the second time.

The structure of the logic control circuit is not limited in the embodiment of the application, and the logic control circuit can be used as long as whether the first comparison result and the second comparison result meet the preset silent state condition of the shared bicycle can be judged. In an implementation manner when the logic control circuit performs the determination, the first comparison result includes a high level and a low level, and the second comparison result includes a high level and a low level, which are the same as those in step S102 in the first embodiment and are not described herein again.

The second timing circuit is connected with the lock control circuit and specifically used for: acquiring a lock switching state of a lock control circuit (the lock switching state indicates that an order is available when a lock is opened, and the lock switching state indicates that no order is available when the lock is closed); and if the lock switch state is changed to be the lock closing state at the second moment, starting timing based on the second moment, and outputting a high level of a second pair of high and low levels as a second comparison result when the duration of the current order-free state is greater than a second preset duration threshold.

Therefore, the power supply system of the embodiment of the application can be realized through hardware, a timer and a logic circuit are additionally arranged in the hardware circuit, the silent state is automatically judged and identified through hardware logic, software processing control logic is reduced, and the stability and the reliability of the system are improved.

If the state of the lock switch is changed to lock opening, the second timing circuit is refreshed all the time, namely the second timing circuit performs reset operation, namely the current timing duration of the second timing circuit is zero all the time, the current uncharged duration is zero and is less than a second preset duration threshold, and the second comparison result is a low level.

It should be understood that as another example, the first timing circuit is specifically configured to: acquiring the charging state of a solar charging circuit; and if the charging state is changed into uncharged at the first moment, starting timing based on the first moment, and outputting a low level of the first pair of high and low levels as a first comparison result when the current uncharged duration is greater than a first preset duration threshold. The second timing circuit is specifically configured to: acquiring a lock switching state of a lock control circuit; and if the lock switch state is changed to be the lock closing state at the second moment, starting timing based on the second moment, and outputting a low level of a second pair of high and low levels as a second comparison result when the duration of the current order-free state is greater than a second preset duration threshold.

Accordingly, the first timing circuit is further configured to: if the charging state is changed to be charging, clearing the current timing duration of the first timing circuit, and outputting a high level of the first pair of high and low levels as a first comparison result, wherein the second timing circuit is further configured to: and if the lock switch state is changed to be the lock opening state, resetting the current timing duration of the second timing circuit, and outputting a high level of a second pair of high and low levels as a second comparison result.

It is also understood that the first timing circuit may output one of a high level and a low level if the charging state changes to charging; the first timing circuit may output the other of the high level and the low level if the charged state is changed to the uncharged state at the first timing. Correspondingly, if the lock switch state is changed to be the lock closing state at the second moment, the second timing circuit outputs one of the low level and the high level; if the lock switch state changes to lock open, the second timing circuit outputs the other of the low level and the high level.

Optionally, in an embodiment of the present application, the power supply system further includes a switch circuit, and the switch circuit is connected to the logic and circuit and the power supply circuit of the power supply system. The switch circuit carries out switching processing on the power supply of the power supply circuit through the control of the output signal of the output end of the logic AND gate circuit, and controls the power supply mode of the power supply circuit. When the output information indicates that the switching circuit is turned off, the power supply circuit enters a low-power-consumption power supply mode. Optionally, in an embodiment of the present application, when the output information indicates that the switching circuit performs the turn-on process, the power supply circuit enters a normal power supply mode.

Alternatively, the battery in this example may be a lithium battery. The whole circuit system of the shared bicycle comprises a power supply system (a power supply system comprising a solar panel, a charging chip and a battery, a power supply control system comprising a timer A, a timer B, a logic AND gate circuit and a PMOS switching tube, and the like), and the power supply system can also comprise a main control chip. The power supply system can also enable external power supply to an external communication device (alternatively referred to as a networked positioning module, e.g., a GPS device or a bluetooth device, etc.).

(2) The charging chip is connected with the timer A, the charging chip is connected with the timer B through the main control chip, the output end of the timer A and the output end of the timer B are respectively connected with two input ends of the logic AND gate circuit, and the output end of the logic AND gate circuit is connected with the grid G of the PMOS switch tube.

The power supply circuit can also supply power to the main control chip.

Specifically, the timer a, the timer B, and the logic and circuit may all be powered by the entire circuitry of the shared bicycle, i.e., by the charging chip.

(3) When the solar panel shines the sun, the battery is charged, the charging voltage is not 0, the timer A is refreshed all the time, namely the timer A is in a reset state, the timing duration of the timer A is zero, and the timer A outputs a low level; when the solar panel is not sunned, the charging voltage is 0, the charging chip does not charge the battery, and the timer A automatically starts to time. When the time length of the timer A reaches the preset time Mh, the timer A outputs a high level, namely X is a high level. As shown in fig. 6, fig. 6 is a schematic diagram of output levels of a timer according to another embodiment of the present application under different scenarios. And when the time length of the timer A from the last charging is more than M hours, outputting a high level H, and when the time length of the timer A from the last charging is less than or equal to M hours, outputting a high level L.

(6) When the solar panel shines the sun (or the vehicle has an order), the timer A (or the timer B) is automatically reset, the timer A outputs X (or the timer B outputs Y) and is switched to be in a low level, the logic AND gate circuit outputs Z to be in a low level, the PMOS switch tube is switched to be in a conducting state, the networking positioning module recovers power supply, and the whole circuit system of the shared single vehicle is automatically switched to be in a normal standby mode, namely, the normal power supply mode is entered.

In the related art, when the vehicles are actually operated, a considerable proportion of the vehicles are in a silent state for a long time, such as long-time storage, vehicle detaining, no order of the vehicles and other scenes, and the solar panel can not shine the sun all the time, so that the battery can not be charged. Under the scenes of the kind, the vehicle is still in a high-power-consumption standby state under the background of no order and no charging for a long time, the battery power can be exhausted quickly, the vehicle is disconnected, the high low power rate and the no-heartbeat rate are caused, and great troubles are brought to the normal operation and maintenance of the vehicle.

The power supply system provided by the embodiment of the application is realized through hardware, a timer and a logic circuit are additionally arranged in the hardware circuit, and the silent state is automatically judged and identified through hardware logic, so that software processing control logic is reduced, and the stability and reliability of the system are improved.

Based on the power supply system provided in fig. 6, the embodiment of the present application further provides a specific example to describe the power supply control method in the embodiment of the present application, which is specifically as follows. As shown in fig. 7, fig. 7 is a flowchart of a power supply control method according to another embodiment of the present application. This is achieved by the following steps S701 to S705.

Step S701, start timer a, timer B, and logic and gate circuit.

And after the whole circuit system of the shared bicycle is powered on, the timer A, the timer B and the logic AND gate circuit are started. The entire circuit system of the shared bicycle in this example includes a power supply system (a power supply system including a solar panel, a charging chip and a battery, a power supply control system including a timer a, a timer B, a logic and gate circuit and a PMOS switch tube, etc.), and the power supply system may further include a main control chip. The power supply system can also enable external power supply to an external communication device (alternatively referred to as a networked positioning module, e.g., a GPS device or a bluetooth device, etc.).

Step S702, if the charging voltage and the charging current exist, the timer A is emptied; if there is an order, the timer B is cleared.

If the charging chip charges the battery, the charging voltage and the charging current exist, the timer A is refreshed all the time, and the timer B is refreshed if the main control chip has an order.

And step S703, whether the timing duration of the timer A and the timer B is simultaneously greater than H hours.

Step S703 determines whether the shared bicycle is a silent vehicle by determining whether the counted time lengths of the timer a and the timer B are simultaneously longer than H hours. In this example, it is determined whether the timing durations of the timer a and the timer B are simultaneously greater than H hours, that is, M and N in fig. 6 are the same and are both H. When the charging chip is not charged for H hours continuously, the timer A outputs a high level; and when the main control chip continuously has no order H, the timer B outputs high level.

Step S704, if yes, the logic AND gate circuit controls to disconnect the PMOS switch tube, the power supply mode with low power consumption is entered, and the steps S702 to S705 are continuously circulated.

When the output levels of the timer A and the timer B are high levels at the same time, namely the vehicle continuously has H hours and has no order, the solar panel does not charge the battery through the charging chip, the vehicle is in a silent state, the logic AND gate circuit outputs the high levels, the PMOS switch tube is disconnected, the power supply of the networking positioning module is automatically cut off, and the whole circuit system of the shared bicycle enters a low-power-consumption power supply mode, so that the power consumption in the silent state is reduced, the battery utilization rate is improved, and the operation and maintenance cost is reduced.

Step S705, if not, the logic AND gate circuit controls to turn on the PMOS switch tube, enters a normal standby mode, and continues to loop the steps S702 to S705.

When a new order is made for the vehicle or the solar panel recharges the battery through the charging chip, the timer A or the timer B refreshes the timing and returns to zero, the timer A or the timer B outputs a low level, the logic AND gate circuit outputs a low level, the conduction of the PMOS switch tube is recovered, the power supply of the networking positioning module is recovered, namely, the low-power-consumption power supply mode is automatically exited, and the whole circuit system of the shared bicycle enters a normal standby mode.

In the related art, the related system for sharing a bicycle cannot distinguish the silent state through automatic detection by the hardware included in the related system. In the related technical scheme, the vehicle in the silent state (even if no order is provided) is always in a normal standby state, and has high power consumption and high power consumption, and the battery utilization rate is low until the battery is consumed to low power.

The timer A, the timer B and the logic AND gate circuit are additionally arranged on hardware, so that the preset logic relation is realized. When the last charging time and the last order time are both greater than the preset time H, the two timers output high levels, the vehicle is judged to be a silent vehicle, the logic AND gate circuit outputs the high levels, and the PMOS switch tube is controlled to be disconnected, so that the power supply of the networking positioning module is disconnected, and the whole circuit system of the shared bicycle automatically enters a low-power-consumption power supply mode. When the silent vehicle starts to charge or an order is generated, the whole circuit system of the shared bicycle can automatically recover the power supply of the networking positioning module through a hardware circuit, and the whole circuit system vehicle of the shared bicycle can automatically recover a normal standby mode.
