The present specification provides a charging device sharing a power bank, as shown in fig. 1A to 1B.
Fig. 1A to fig. 1B are schematic diagrams of a charging device sharing a charger baby according to the present disclosure.
Fig. 1A is a schematic diagram of the shared power banks on the charging device of the shared power bank being borrowed, and fig. 1B is a schematic diagram of the shared power banks on the charging device of the shared power bank being located in the charging bin for charging. Charging device can include a plurality of storehouses that charge, sharing treasured and the solenoid valve of charging, and every storehouse that charges corresponds a sharing treasured that charges, is equipped with a solenoid valve in every storehouse that charges, and the solenoid valve is used for popping out the treasured storehouse that charges with the sharing, and charging device is equipped with switch, controller and solenoid valve protection circuit, solenoid valve protection circuit connection switch, controller and solenoid valve.
The controller in the charging device can monitor the voltage in the electromagnetic valve protection circuit and can also control the disconnection and the connection of a power switch in the electromagnetic valve protection circuit, the electromagnetic valve protection circuit is electrified after the power switch is closed, the electromagnetic valve can pop the shared charging treasure out of the charging bin, and the electromagnetic valve protection circuit is powered off to protect the electromagnetic valve after the power switch is disconnected.
The following description will be made of a method for protecting a solenoid valve of a shared power bank provided in the present specification, standing on the perspective of a controller.
Fig. 2 is a schematic flow chart of a method for protecting an electromagnetic valve of a shared power bank in this specification, which specifically includes the following steps:
s201: and for each charging bin, responding to a use instruction of the shared charging treasure in the charging bin, and acquiring a voltage value of the electromagnetic valve protection circuit corresponding to the charging bin.
In practical Application, a user can request to use the shared charger bank through a terminal or an Application (APP) installed in the terminal, after receiving a use instruction of the user for a certain shared charger bank, the electromagnetic valve protection circuit of a charging bin where the shared charger bank is located is powered on, the electromagnetic valve starts to work to pop up the shared charger bank, and in order to avoid that the electromagnetic valve or other devices are burnt out due to current overload in the electromagnetic valve protection circuit, the controller can monitor the voltage of the electromagnetic valve protection circuit, and the electromagnetic valve and other devices are protected. The terminal mentioned here can refer to a mobile phone, a notebook computer, a tablet computer, and the like.
Based on this, the controller can respond to the use instruction of sharing the treasured that charges in this storehouse for each storehouse of charging, acquires the voltage value of the solenoid valve protection circuit that this storehouse of charging corresponds to. The term "responding to the use instruction for the shared power bank in the charging bin" means that a request of a user to use the shared power bank in the charging bin is received at this time, the user needs to use the shared power bank in the charging bin, the power switch is turned on at this time, the electromagnetic valve protection circuit is powered on, and therefore the controller needs to obtain the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin at this time.
The voltage values of the electromagnetic valve protection circuits corresponding to the multiple charging bins can be monitored by one controller, or the voltage values of the electromagnetic valve protection circuits corresponding to the multiple charging bins can be monitored by multiple controllers, for example, one controller monitors the voltage value of the electromagnetic valve protection circuit corresponding to one charging bin. The number of controllers is not limited in this specification. The controller mentioned herein may be a Micro Controller Unit (MCU), or other types of controllers.
An Analog to Digital Converter (ADC) may be included in the controller, and the ADC may convert an Analog signal to a Digital signal. Therefore, the controller can acquire the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin through the ADC in a Direct Memory Access (DMA) mode, acquire the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin through the DMA mode, and do not need to occupy a Central Processing Unit (CPU) resource in the controller. The controller can also obtain the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin at regular time, that is, the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin is obtained at intervals, and whether the voltage value is lower than a set threshold value is judged.
It should be noted that in practical applications, the voltage value that the controller can monitor may have an upper limit, for example, assuming that the controller can only monitor voltage values up to 4 volts, the voltage of the power supply in the electromagnetic valve protection circuit is 12 volts, the voltage needs to be divided in the electromagnetic valve protection circuit, the controller determines the voltage value after voltage division, specifically, the electromagnetic valve protection circuit can also comprise at least one sampling resistor, these sampling resistors can be used to divide the voltage in the solenoid valve protection circuit, and the controller, in response to a usage command directed to the shared charger bank in the charging bay, a voltage value obtained by dividing the voltage of the electromagnetic valve protection circuit corresponding to the charging bin through at least one sampling resistor may be obtained as the obtained voltage value of the electromagnetic valve protection circuit corresponding to the charging bin, as shown in fig. 3.
Fig. 3 is a schematic diagram of a protection circuit of a solenoid valve provided in the present specification.
In fig. 3, the solenoid valve protection circuit includes 2 sampling resistors, and the 2 sampling resistors can divide the voltage in the solenoid valve protection circuit, and if the current passing through the solenoid valve is overloaded, the voltage of the power supply in the solenoid valve protection circuit will be sharply reduced, and the voltage value between the two sampling resistors will also be reduced. In this example, the solenoid valve protection circuit includes 2 sampling resistors, and the number and the resistance value of the sampling resistors may be set according to actual requirements in practical applications, which is not limited herein.
S202: and after the voltage value is lower than a set threshold value, determining that the current in the electromagnetic valve protection circuit corresponding to the charging bin is overloaded, and taking a power switch in the electromagnetic valve protection circuit corresponding to the charging bin as a target switch to be switched off.
After the controller obtains the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin, whether the voltage value is lower than a set threshold value or not is determined, after the voltage value is lower than the set threshold value, the current overload in the electromagnetic valve protection circuit corresponding to the charging bin can be determined, and a power switch in the electromagnetic valve protection circuit corresponding to the charging bin is used as a target switch to be switched off.
That is to say, the method determines the current in the electromagnetic valve protection circuit by monitoring the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin, that is, whether the current passing through the electromagnetic valve is overloaded or not, if the current passing through the electromagnetic valve is overloaded, the voltage in the electromagnetic valve protection circuit will drop rapidly, and the controller determines that the voltage value in the electromagnetic valve protection circuit is lower than the set threshold value, that is, the current overload in the electromagnetic valve protection circuit can be determined, and the power supply in the electromagnetic valve protection circuit is disconnected.
In addition to the above, the controller may determine whether the target switch should be turned off in various ways, for example, after a time period in which the voltage value of the solenoid valve protection circuit is lower than the set threshold value exceeds a first set time period, the target switch may be turned off. That is, after the solenoid valve protection circuit is powered on, if the voltage value of the solenoid valve protection circuit is lower than the set threshold value in the first set time period, it indicates that the current of the solenoid valve protection circuit is overloaded in the first set time period, and the controller needs to turn off the target switch. The first set time period and the set threshold mentioned here may be set according to actual requirements.
It should be noted that, in order to determine whether the current in the solenoid valve protection circuit is briefly overloaded, whether the fault in the solenoid valve protection circuit is temporary, and whether the fault disappears automatically afterwards, the controller may try to control the target switch to be closed again, so that the solenoid valve protection circuit is powered on, and determine whether the current is still overloaded. For example, if the solenoid valve is short-circuited due to water inflow, but the water inflow is very small, and the current may be restored to normal after being briefly overloaded and then the controller may control the target switch to be closed to determine whether the current is still overloaded.
Therefore, the controller can close the target switch after determining that the off duration of the target switch reaches the second set duration, and then, if the voltage value of the solenoid valve protection circuit corresponding to the charging bin is still lower than the set threshold, it can be determined that the charging bin has a fault, and send a fault repair request for the charging bin to the preset shared charger maintenance platform, so as to repair the charging bin through the shared charger maintenance platform.
The second set time period mentioned above may be set according to an actual requirement, the disconnection duration time period refers to a duration time after the controller disconnects the target switch, that is, the controller disconnects the target switch, and after the second set time period, the target switch may be closed, so that the electromagnetic valve protection circuit corresponding to the charging bin is powered on, and if the current of the electromagnetic valve protection circuit corresponding to the charging bin is still overloaded, it may be determined that the fault in the charging bin is not recovered, and since the electromagnetic valve may have a fault, and also may be a fault in a part of lines or other devices connected to the electromagnetic valve, the controller may send a fault repair request for the charging bin to the shared charger maintenance platform, and may notify a maintenance person to repair the fault in the charging bin.
The controller can directly try to close the target switch after the off duration of the target switch reaches a second set duration, and can also try to close the target switch for multiple times, and if the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin is still lower than the set threshold value after the target switch is tried to be closed for multiple times, the charging bin needs to be repaired.
Specifically, the controller may close the target switch for the nth time after determining that the duration of opening of the target switch reaches the second set time, and re-determine the first set time, if the re-determined first set time is passed, the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin is still lower than the set threshold, open the target switch, and close the target switch for the (N + 1) th time after the second set time, until the re-determined first set time is lower than the specified time, the voltage value of the electromagnetic valve protection circuit corresponding to the charging bin is still lower than the set threshold, and determine that the charging bin is faulty, wherein the first set time re-determined when the target switch is closed for the (N + 1) th time is shorter than the first set time re-determined when the target switch is closed for the nth time, N is a positive integer, where the specified time mentioned herein may also be set according to actual requirements, as shown in fig. 4.
Fig. 4 is a schematic flow chart of a controller that attempts to close a target switch multiple times according to the present disclosure.
As can be seen from fig. 4, after the target switch is turned off, the controller may control the target switch to be turned on for a plurality of times, after each time the target switch is turned on, the first set time length needs to be determined again, and when each time the target switch is turned off, the first set time length determined by the controller needs to be shorter than the last time. For example, if the first set time period is 1 second after the target switch is closed for the first time, the first set time period may be 0.5 second when the target switch is closed for the second time, and so on, and the first set time period should be shorter when the target switch is closed for the third time.
After each target switch is closed, if the voltage value of the electromagnetic valve protection circuit of the charging bin is still lower than the set threshold after the redetermined first set time length, namely, the current of the electromagnetic valve protection circuit of the charging bin is continuously overloaded, the controller needs to continuously control the target switch to be switched off, and after the second set time length, the target switch is controlled to be switched on again until the redetermined first set time length is lower than the specified time length, namely, the redetermined first set time length is too short, at the moment, the voltage value of the electromagnetic valve protection circuit of the charging bin is still lower than the set threshold, the charging bin can be determined to have an unrecoverable fault, and when the target switch is switched off, the charging bin is determined to have the fault, and a fault repair request for the charging bin is sent to the charger maintenance platform.
Of course, if the voltage value of the electromagnetic valve protection circuit of the charging bin exceeds the set threshold value and is not lower than the set threshold value subsequently in the process of closing the target switch for multiple times, it indicates that the current of the electromagnetic valve protection circuit of the charging bin is recovered to be normal, and it is not necessary to send a fault repair request for the charging bin to the charge pal maintenance platform.
It can be seen from the above method that the method can monitor the voltage value in the solenoid valve protection circuit corresponding to each charging bin through the controller, thereby being capable of quickly determining whether the current passing through the solenoid valve is overloaded or not, and determining whether the current passing through the solenoid valve is overloaded for a long time or not through the method, and the power switch is switched off without short overload.
In the prior art, the electromagnetic valve may be protected by a self-recovery fuse, and whether the current passing through the electromagnetic valve is overloaded may be determined by an electronic load switch and a discrete circuit, so as to achieve the effect of protecting the electromagnetic valve. By the method, a resistor does not need to be connected in series in the circuit to cause power loss, and the set threshold value can be configured in a mode of programming the controller, so that compared with the two prior arts, the method can reduce the power loss and change the condition for judging whether the current of the electromagnetic valve is overloaded.
Based on the same idea, the present specification further provides a corresponding shared charger bank solenoid valve protection device, as shown in fig. 5, in order to provide a charger device and a shared charger bank solenoid valve protection method for one or more embodiments of the present specification.
